Communication Theories Matrix Essay

Instructions: Complete the following matrix by filling in the box for each of the five communication theories with the following four items: the theory definition, the main principles of the theory, a real-world theory example, and an application of each theory to virtual communication. Theory definition Main principles of the theory Real-world theory example Application of each theory to virtual communication Social Exchange Theory Theory that attempts to explain human behavior in terms as behavioral psychology. The main principle of this theory is social relationships are the outcome of an exchange process with the purpose of maximizing the benefits and minimizing costs. An example of this theory is asking someone out on a date, but you dislike the fact that he/she lacks money or good looks, but he/she is caring and fun to hang out with the therefore you go because the benefits outweigh the cost. The rewards of virtual communication include freedom from the constraints of time and space but the costs is the possibility for misunderstanding when we are not able to see each other’s facial expressions or tone of voice. Systems Theory Systems theory is an open system of interdependent elements, employing input variables and process variables to yield output. The main principle is to receive input, process input and yield an output An example would be in a group you collectively develop a task from input and expect productivity as a output. Connection through the internet can alter patterns in many ways making the system more open. Symbolic Convergence Theory Theory of communication that explains how certain  types of communication shape a group’s identity and culture, which in turn influence other dynamics. Share group fantasies create symbolic convergence.  In a business symbolic convergence is used to determine what the customers like about the business and that allows the business to cater to the customer. In, virtual communication the possibilities for visual, verbal, or auditory communication can make new avenues for fantasy themes and group identity. Structuration Theory Theory that provides a general framework  and explains how people structure their groups by making active use of rules and resources. The main function of this theory is to focus attention on individuals’ behaviors in groups rather than on dynamics of groups. Basketball team is a example of structuration theory, because it has structure and rules that all members must follow. The coach is the leader and implements the rules for the team to follow. use of computers, e-mail,  and the internet as resources can expand the repertoire of structures available to group members. Functional Theory Communication in groups that functions to promote sound reasoning, prevent errors, and build relationships among all members. Focus on results and outcomes of group behaviors and structure. In a group where members use this theory to make decisions and to solve problems. Use of virtual group communication to enhance areas of group interaction by extending dialogue beyond a meeting room.

Person Centred Approach Essay

The definition of person centred values is treating and seeing people in a care setting as equals, who are involved in decision making to promote an independent way of life and to ensure that the care that is provided is appropriate to their needs. It takes into account service users views and needs and places them, along with their family at the centre of all decision making. Working in a way that embeds person centred values is important to meet the needs of my service user. With my clients it helps to build relationships with them and their family members to ensure a good quality of life and provide the best possible quality of care. This ranges from me attending to my service users personal care needs in a respectful way and to support them to achieve tasks on their own, to choices of what activities they would like to do that can help them to express their individuality or help them to create new relationships and overcome any feelings of social exclusion or devaluation. I also believe it’s important to respect any religious or cultural beliefs that they may have and support the individual to follow their chosen faith. Read more:  Person Centred Care Firstly I would look at the way in which I communicate with my service user. If they are verbal the simplest way I find out about the individual is to talk directly to them as it allows them to fully express themselves and make their own decisions. If non verbal then I would communication methods such as makaton, picture cards and visual aids to learn of their likes and dislikes. Another way is to speak with siblings as they could provide information the client may be unaware of or may have forgotten but also so they are included in the building of the care plan and it helps me build an understanding and a relationship with them. Talking with social workers, previous support workers, doctors or any other professional involved in the clients care an also provide information about their preferences and anything that may be important to the individual. With these methods it helps me find as much information as possible about my service user. In order to take into account the history, preferences, wishes and needs of an individual when planning care and support I would refer to the principles of person centred care. Rather than just supplying a service, each person should be treated as an individual by offering a personalised service specific to their needs and preferences. For example if an individual enjoyed an activity such as walking but needed support to do so I would plan a time for a walk so that the individual would get enjoyment from doing activities they choose and feel valued. Also, they should be treated them with the same dignity and respect you would want for a member family of your own. Refer to support plans to ensure the highest level of person centred care is maintained. Each individual’s care plan outlines and details the service user’s preferences and day to day requirements so that they receive the specific care and daily support they require from the level of support required with an individual’s personal hygiene and how to do it in a respectful way to what food and activities they like. The information is centred on the individuals wants and needs to ensure independence and choice rather than control, choice should always be offered regardless of importance of the activity or task, therefore each individual’s care plan contributes to working in a person centred way. The term consent means giving permission to do something or agreement to an action and in a care setting consent is needed for a number of things. With my clients I need to ask for consent for administering medication, for help with bills, finances and banking, help with certain type of care such as bathing and personal hygiene. It’s important to gain consent for all activities as lack of it could be deemed as abuse as I would forcing someone to perform or to take part in a task or an activity they don’t want to be involved in. Consent however should not just be gained, but the client must fully understand what they are consenting to and any possible implications that the action or task can imply. It is also essential for protecting myself from any legal challenge. There are a few ways to establish an individual’s consent but it depends upon the individuals preferred communication. The methods I use with my clients are verbal, written notes, visual aids such as picture cards, makaton, some individuals communicate physically with body movements such as a nod or through a representative or advocate. Any of these are forms establishing consent that i would look to use with my clients. Establishing consent will vary as each individual’s capacity to consent is assessed. If consent cannot be established first steps would be to not carry out the task and document the information. If a person is mentally incapable of providing consent then you should refer to the individuals care/support plan that may have been established at a time when they were capable of making informed decisions. If this fails, consent can be given by next of kin or an advocate however I would ensure my client must be involved as much as possible to adhere to person centred values. Active participation is a way of working that allows an individual to be completely involved in every aspect of their lives. This could be what my service users have to eat, what they wear when they go out or go to work in, or it could be planning tasks and activities for the week ahead, deciding on where to go such as day trips out or holidays, arranging appointments to the doctors or the dentists and active participation in services that relate to their own care. Helping to be in control of their lives rather that a passive recipient. Active participation helps individuals by benefitting them in a number of ways. I believe it gives them independence and makes the service user feel in control of their own lives rather than having decisions made for them or having few choices. There are many benefits I’ve noticed such as growth in confidence in social situations, a sense of well being, a sense of achievement of taking control of their lives and I’ve noticed the mental and physical stimulation it also brings. Also encouraging individuals to participate in the planning and arranging of their own care increases their self confidence, independence and it is empowering. There are many ways to reducing barriers of active participation. In order to reduce any barriers to active participation you have to look at what the barriers could be. They could be lack of confidence or self esteem, a lack of opportunity to activities, difficulty in communication and lack of patience of others. To overcome these barriers I support my service users by offering them choices and in every aspect of their day to day lives and offering them opportunity to plan and do activities they enjoy which improves their confidence. I think it’s very important to have the patience to listen to service users and take time to understand how they feel and I find by discussing why they feel like this and talking through it can increase their feeling of self esteem. Communication barriers can be overcome by staff development and training, language and makaton are tools that can be learnt, but there other ways like picture cards and hand gestures I use with some service users to offer choices and to make decisions when they are non verbal. The method I find best to encourage active participation is by communicating and offering choices and then giving praise and encouragement to service users to increase their confidence to then go on to make more decisions in different aspect of their lives for themselves. I find it’s good to look for local events or if they show an interest in a hobby you could find out about local groups that would be prepared to support the individual to participate. You should always highlight the benefits of the activity and getting family members to join in with activities can make a big difference to encouraging participation from individuals. I would support an individual to make informed choices by giving the individual the full information regarding that decision. I would explain the positive and the negative effects of that decision regardless of my beliefs or views as my personal view should not influence an individual’s choice. The choices and decisions can be as simple offering the full information on items when supporting individuals with shopping, giving information on price and helping to find offers or decisions that may require risk assessments to make the individual fully aware of the any risks that may be involved. I believe all staff in a care setting should help to  empower their client by offering the information, knowledge and confidence to make informed decisions. I think risk taking can be part of an individual’s choices because there is risk in many day to day things that we do. Due to the nature of an individual’s disability, a simple task could be deemed a risk and would need risk assessing to make them fully aware of any potential dangers or threats to the individual’s safety. It’s important to make individuals aware of any risks or hazards Risk assessment processes are used to make an individual aware of the positive and negative consequences involved when for example taking part in an activity, we look at and record the risks and hazards involved and then decide if the risk is worth taking. However there are benefits that have to be taken in to consideration as new activities promote confidence and empowers individuals to live more independent lives. Having choice is an individual’s right, risk assessments provide support for them to make decisions in the safest way possible. I believe a worker’s personal views should not influence an individual’s choices because that is taking away their right to make informed choices. My views for example are not fact and should not be used to influence any decisions or life choices. I could inform an individual if a certain food was bad for them and suggest a healthier option however whatever they decide is their choice. Another example is religious or cultural choices and beliefs, my views are my own and I would support them to attend religious or cultural services and acknowledge religious holidays.

Changes And Urban Expansion In Greater Dhaka Environmental Sciences Essay

The analysis revealed that significant growing of built-up countries in Greater Dhaka over the survey period resulted important lessening in the country of H2O organic structures, cultivated old termland, following term flora and wetlands. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Rapid old termurban expansionnext term through infilling of low-lying countries and glade of flora resulted in a broad scope of environmental impacts, including habitat quality. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms. Urbanization is one the most widespread anthropogenetic causes of the loss of cultivable old termlandnext term ( Lopez, Bocco, Mendoza, A ; Duhau, 2001 ) , habitat devastation ( Alphan, 2003 ) , and the diminution in natural flora screen. The transition of rural countries into old termurbannext term countries through development is presently happening at an unprecedented rate in recent human history and is holding a pronounced consequence on the natural operation of ecosystems ( Turner, 1994 ) . Although old termurbannext term countries presently cover merely 3 % of the Earth ‘s old termlandnext term surface, they have marked effects on environmental conditions at both local and planetary graduated tables ( [ Herold etA al. , 2003 ] and [ Liu and Lathrop, 2002 ] ) , including clime old termchangenext term ( Grimm, Grove, Pickett, A ; Redman, 2000 ) . Since ecosystems in old termurbannext term countries are strongly influenced by anthropogenetic activities, well more attending is presently being directed towards supervising old termchangesnext term in old termurban landnext term usage and old termlandnext term screen ( LULC ) ( Stow A ; Chen, 2002 ) . Such surveies are peculiarly of import because the spacial features of LULC are utile for understanding the assorted impacts of human activity on the overall ecological status of the old termurbannext term environment ( Yeh A ; Li, 1999 ) . LULC old termchangenext term due to human activities is presently continuing more rapidly in developing states than in the developed universe, and it has been projected that by the twelvemonth 2020, most of the universe ‘s mega metropoliss will be in developing states ( World Bank, 2007 ) . Increasing population in developing metropoliss has caused rapid old termchangesnext term in LULC and increased environmental debasement ( Holdgate, 1993 ) . The consequence of population is peculiarly relevant given that the planetary old termurbannext term population is proj ected to about duplicate by 2050 ( UN, 2008 ) . In order to extenuate the damaging effects associated with old termurbannext term growing on the environment and to keep optimum ecosystem operation ( Fang, Gertner, Sun, A ; Anderson, 2005 ) , spacial and temporal LULC forms, and the factors impacting these old termchangesnext term ( Serra, Pons, A ; Sauri , 2008 ) , are well of import in developing rational economic, societal and environmental policies ( Long, Tang, Li, A ; Heilig, 2007 ) . Bangladesh has experienced rapid old termurbannext term population growing in recent decennaries ; the population numbered 14.1 million in 1981, 22.5 million in 1991, 31.1 million in 2001 ( BBS, 2001 ) and 35 million in 2005 ( CUS, NIPORT, A ; MEASURE, 2006 ) . Rapid urbanisation has led to the transmutation of rural countries into developed countries, and it has been estimated that more than 809A km2 of agricultural old termlandnext term is converted to metropoliss, roads and substructure yearly ( BBS, 1996 ) . The lessening in agricultural activities, the largest sector of the Bangladeshi economic system, and the attendant loss of cultivated old termlandnext term is likely to lend to landlessness, nutrient deficits and endanger the economic system ( Ahmad, 2005 ) . Dhaka, the capital of Bangladesh, is expected to be the 3rd largest metropolis in the universe by 2020 ( World Bank, 2007 ) and the rapid old termurbannext term growing experienced by the metropolis in recent decennaries is one of the highest in the universe ( [ Islam, 1999 ] and [ Islam, 2005 ] ) . old termUrban expansionnext term of Dhaka was slow in the 1950s, but strong growing followed the independency of Bangladesh in 1971 ( Chowdhury A ; Faruqui, 1989 ) . The considerable growing observed in the population of Dhaka is thought to hold occurred in response to large-scale rural-previous termurbannext term migration, which has contributed, significantly to the increased rate of urbanisation ( Islam, 1996 ) . To day of the month, the environmental and socio-economic sustainability of Dhaka, which is indispensable for development planning, has received comparatively small attending. This has resulted in widespread environmental jobs across the metropolis, mostly stemming from unpla nned urbanisation, extensive old termurbannext term poorness, perennial episodes of implosion therapy, significant growing of slums, development of resources, and the misdirection of limited old termlandnext term resources ( Hasan A ; Mulamoottil, 1994 ) . Geographic Information Systems ( GIS ) and distant detection ( RS ) are powerful and cost-efficient tools for measuring the spacial and temporal kineticss of LULC ( [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Lambin etA al. , 2003 ] and [ Serra etA al. , 2008 ] ) . Distant feeling informations provide valuable multi-temporal informations on the procedures and forms of LULC old termchange, following term and GIS is utile for function and analysing these forms ( Zhang etA al. , 2002 ) . In add-on, retrospective and consistent synoptic coverage from orbiters is peculiarly utile in countries where old termchangesnext term have been rapid ( Blodget, Taylor, A ; Roark, 1991 ) . Furthermore, since digital archives of remotely sensed informations provide the chance to analyze historical LULC old termchanges, following term the geographic form of such old termchangesnext term in relation to other environmental and human factors can be evaluated. Numerous old termchangenext term sensing methods have been developed to measure fluctuations in LULC utilizing satellite informations ( [ Coppin etA al. , 2004 ] , [ Lu etA al. , 2004 ] and [ Singh, 1989 ] ) . Of these techniques, the pre- and post-classification comparings have been extensively used ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) . In the pre-classification attack, processs such as image differencing ( Toll, Royal, A ; Davis, 1980 ) , band rationing ( Nelson, 1983 ) , old termchangenext term vector analysis ( Johnson A ; Kasischke, 1998 ) , direct multi-date categorization ( Li A ; Yeh, 1998 ) , flora index differencing ( Townshend A ; Justice, 1995 ) and principle constituent analysis ( Fung A ; LeDrew, 1987 ; Hartter, Lucas, Gaughan, A ; Aranda, 2008 ) have been developed ( [ Hardin etA al. , 2007 ] , [ Jensen, 1996 ] and [ Singh, 1989 ] ) . The basic premiss of these processs is that old termchangesnext term in LULC consequence in differences in the pel c oefficient of reflection values between the day of the months of involvement. However, while these techniques are effectual for turn uping old termchange, following term they can non place the nature of old termchangenext term ( Ridd A ; Liu, 1998 ) . Conversely, post-classification comparings examine old termchangesnext term over clip between independently classified old termlandnext term screen informations. Despite the troubles associated with post-classification comparings ( [ Coppin etA al. , 2004 ] and [ Singh, 1989 ] ) , this technique is the most widely used for placing LULC old termchangesnext term ( [ Jensen, 1996 ] and [ Lu etA al. , 2004 ] ) , peculiarly in old termurbannext term environments ( Hardin etA al. , 2007 ) . However, one of the disadvantages associated with this attack is that the truth of the end point LULC old termchangenext term maps depends on the truth of the single categorization, intending that such techniques are capable to error extension ( Yuan, Sa waya, Loeffelholz, A ; Bauer, 2005 ) . However, such post-classification techniques are peculiarly utile for bring forthing ‘from-to ‘ maps ( Jensen, 1996 ) , which can be used to clear up the magnitude, location and nature of the old termchangesnext term shown ( Howarth A ; Wickware, 1981 ) . In add-on, the technique can be employed utilizing informations acquired from detectors with different spatial, temporal and spectral declarations ( [ Alphan, 2003 ] and [ Coppin etA al. , 2004 ] ) . RS is really effectual for exemplifying the interactions between people and the old termurbannext term environments in which they live ( Gatrell A ; Jensen, 2008 ) . Space-borne orbiter informations are peculiarly utile for developing states due to the cost and clip associated with traditional study methods ( Dong, Forster, A ; Ticehurst, 1997 ) , and these techniques have become feasible options to conventional study and ground-based old termurbannext term mapping methods ( Jensen, Hodgson, Tullis, A ; Raber, 2004 ) . Several surveies have demonstrated the pertinence of RS to developing sourcing information and for back uping decision-making activities in a broad scope of old termurbannext term applications ( [ Gatrell and Jensen, 2008 ] , [ Jensen and Cowen, 1999 ] and [ Zeilhofer and Topanotti, 2008 ] ) . In the country of old termurbannext term planning, of import RS research has been conducted to day of the month, peculiarly in old termurban changenext term analysis and the m old of growing ( [ Bahr, 2004 ] , [ Hardin etA al. , 2007 ] , [ Hathout, 2002 ] , [ Herold etA al. , 2003 ] , [ Jat etA al. , 2008 ] , [ Jensen and Im, 2007 ] , [ Liu and Lathrop, 2002 ] , [ Maktav and Erbek, 2005 ] , [ Ridd and Liu, 1998 ] , [ Yang, 2002 ] and [ Yuan, 2008 ] ) , LULC rating ( [ Alphan, 2003 ] , [ Lopez etA al. , 2001 ] , [ Xiao etA al. , 2006 ] , [ Yang and Lo, 2002 ] and [ Yuan etA al. , 2005 ] ) , and old termurbannext term heat-island research ( [ Kato and Yamaguchi, 2005 ] and [ Weng, 2001 ] ) . In peculiar, RS-based multi-temporal old termlandnext term use old termchangenext term informations provide information that can be used for measuring the structural fluctuation of LULC forms ( Liu, Gao, A ; Yang, 2003 ) , which can be applied to avoiding irreversible and cumulative effects of old termurbannext term growing ( Yuan, 2008 ) and are of import to optimise the allotment of old termurbannext term services ( Barnsley A ; Barr, 1996 ) . In add-on, accurate an d comprehensive old termlandnext term use old termchangenext term statistics are utile for inventing sustainable old termurbannext term and environmental planning schemes ( [ Alphan, 2003 ] and [ Jensen and Im, 2007 ] ) . It is hence really of import to gauge the rate, form and type of LULC old termchangesnext term in order to foretell future old termchangesnext term in old termurbannext term development. Small is known about the spacial and temporal dimensions of the LULC old termchangesnext term that have shaped the old termurban expansionnext term of Greater Dhaka. Although most developed states have both recent and extended LULC information, the comparative deficiency of geospatial informations or entree thereto, is prevailing in developing states, peculiarly in Bangladesh. For case, aerial exposure are classified for the populace. The metropolis does non hold any official statistics on old termlandnext term usage forms, and the Master Plans do non incorporate either a map or quantitative information on the bing forms of old termlandnext term usage in the metropolis ( [ Islam, 1996 ] and [ Islam, 2005 ] ) . The old termlandnext term usage forms of Greater Dhaka were officially categorized in 1991 utilizing land observation informations ( Flood Action Plan ( FAP ) 8A, 1991 and [ Islam, 2005 ] ) . Due to the easiness of entree and recent nature of nose count records, the local autho ritiess of Dhaka often use nose count informations to construe old termlandnext term use old termchanges.next term As a consequence, the kineticss of development are non clear and frequently deceptive ( Talukder, 2008 ) . Numerous factors, including fiscal restraints, restricted entree to informations, bureaucratism and deficiency of geospatial expertness in the planning bureaus account for the absence of historical and current old termlandnext term usage informations. Furthermore, every bit many as 18 ministries are involved in the development and planning of Dhaka, and there is a general deficiency of coordination between these organic structures ( Mohit, 1991 ) . This empirical survey will try to place the spatio-temporal form of LULC old termchangesnext term for Greater Dhaka utilizing geospatial informations so that both the scientific community and determination shapers can measure the assorted kineticss impacting LULC old termchangesnext term in this old termurbannext term en vironment. The aims of this survey were therefore to research the features of LULC old termchangesnext term and qualify the underlying drive forces in the Greater Dhaka country by doing usage of remotely sensed informations and socio-economic information. Specifically, the aims are: ( a ) to clarify and measure the LULC old termchangesnext term between 1975 and 2003 ; ( B ) to research the spacial and temporal features of old termurban expansionnext term in this period ; and ( degree Celsius ) to analyse the drive forces of old termlandnext term use old termchange and urban expansion.next term Study country As shown in Fig.A 1, the survey country of Greater Dhaka is located in the centre of Bangladesh between 23A °68aˆ?N ( BTM 533233.91A m ) , 90A °33aˆ? E ( BTM 619052.83A m ) and 23A °90aˆ?N ( BTM 550,952.57A m ) , 90A °50aˆ? E ( BTM 642511.56A m ) , severally. Topographically, the country is level with a surface lift runing from 1 to 14A m ( Fig.A 1 ) , with most old termurbannext term countries located at lifts runing from 6 to 8A m ( FAP 8A, 1991 ) . The metropolis is situated chiefly on an alluvial patio, popularly known as the Modhupur patio dating from the Pleistocene period. The survey country is surrounded by four major river systems: the Buriganga, Turag, Tongi and the Balu, which flow to the South, west, north and east, severally. These rivers are chiefly fed by local rainfall and besides receive overflow from the well larger Ganges, Brahmaputra and Meghna rivers. The metropolis has a humid sub-tropical monsoon clime and receives about 2000A millimeter s of rainfall yearly, more than 80 % of which falls during the monsoon season from June to September. Life-size image ( 137K ) – Opens new window Life-size image ( 137K ) Fig.A 1.A Location of survey country. River webs, embankment and administrative units are draped over a digital lift theoretical account. Brightest countries represent higher lift ; bright grey represents average lift while dark pels show the lowest lift. Position Within Article The happening of heavy monsoon rainfall combined with floodwater overflow from the rivers environing the metropolis mean that Dhaka is really prone to monsoon implosion therapy. The metropolis has experienced a figure of lay waste toing inundations in recent times, with the inundations in 1988, 1998 and 2004 being the most terrible ( Alam A ; Rabbani, 2007 ) . Quantitative appraisals of the countries inundated by these flood events revealed that in 1988, 47.1 % of greater Dhaka were flooded, while in 1998 and 2004, about 53 % and 43 % countries were inundated ( [ Dewan etA al. , 2007 ] , [ Dewan and Yamaguchi, 2008 ] and [ Dewan etA al. , 2006 ] ) . The inundations caused harm to lodging and substructure amounting to US $ 2.2A m in 1988, 4.4A m in 1998 and 5.6A m in 2004 ( Ahmed, Gotoh, A ; Hossain, 2006 ) . The badness of inundation harm was considerable, even in 2004, which was considered more moderate of the three inundations, and which was believed to be the consequence of hapl ess old termurbannext term planning and renewal and development of natural countries, such as wetlands and low-lying countries, that would otherwise hold attenuated the implosion therapy. A survey utilizing hydrological record and RS-based LULC information has shown that inundation continuance and extent has increased well as a consequence of the extended old termurbannext term development on Lowlandss and flood plains of natural river channels ( Dewan A ; Yamaguchi, 2008 ) . It has been suggested that the exposure of Dhaka to deluge harm will increase due to continued unplanned old termurban expansionnext term ( Faisal, Kabir, A ; Nishat, 1999 ) and the consequence of clime old termchangenext term ( Alam A ; Rabbani, 2007 ) , and that these in bend will increase the agony to the dwellers of Dhaka and do extended harm to belongings in the part. Data and methodological analysis Data acquisition and readying Landsat informations ( MSS, TM and ETM+ ) were acquired and used to measure LULC old termchanges and urban expansionnext term in Dhaka. Geometric rectification was performed on all the images utilizing a Landsat TM image of the same country from 1997 as mention. At least 45 land control points ( GCPs ) were used to register the images to the Bangladesh Transverse Mercator ( BTM ) system. GCPs were dispersed throughout the scene, giving a RMS mistake of less than 0.5 pels. A first order multinomial tantrum was applied and images were resampled to 30A m end product pels utilizing the nearest neighbour method. All brooding sets were used in image categorization and the thermic set was excluded. In add-on, geospatial informations including municipal boundaries, route webs, geomorphic units and lift units were used to bring forth GIS beds from beginnings such as Survey of Bangladesh ( SOB ) topographical maps ( sheet no. 79 I 5 A ; 6 ) , municipal boundary map and geomorphic map ( Asaduz zaman, Nasreen, A ; Olsen, 1999 ) . Multi-year socio-economic informations were obtained from Bangladesh Bureau of Statistics ( BBS ) and published literature ( [ Islam, 1996 ] , [ Islam, 2005 ] and [ Siddiqui etA al. , 2000 ] ) . Reference informations, which varied given the retrospective nature of the survey ( Table 1 ) , were used for both developing country choice and for the rating of map truth. In add-on to utilizing high-resolution imagination, intensive fieldwork was conducted in the survey country from 6 February to 22 March 2003 to roll up land truth information for the analysis of the 2003 image. A hardcopy false colour composite ETM+ ( RGB 432 ) image picturing different LULC types was used in the field to place bing old termlandnext term screen characteristics, with particular attending given to spectrally similar characteristics. Based on this fieldwork, a land truth map was prepared for turn uping preparation pels on the image and 200 mention informations points were collected utilizing a planetary placement system ( GPS ) . This GPS information was so overlaid with the image in GIS to choose developing countries and for accuracy appraisal ; 100 of the GPS points were used for trying and the ot her 100 were used for measuring the truth of the categorization.

Position Within Article Image categorization A alteration of the Anderson Scheme Level I method was used to measure LULC old termchangesnext term in this survey ( Anderson, Hardy, Roach, A ; Witmer, 1976 ) . Specifically, extra factors such as the major old termlandnext term usage classs within the survey country and differences in the spacial declaration of the images, which varied from 30 to 79A m, were considered in planing the categorization strategy. Six separate LULC types were identified: H2O organic structures, wetlands/lowlands, built-up countries, cultivated old termland, following term flora and bare soil/landfill ( Table 2 ) . Table 2. old termLandnext term use/cover categorization strategy. old termLandnext term use/Cover Types Description Built-up Residential, commercial and services, industrial, transit, roads, assorted old termurban, following term and other old termurbannext term Bare soil/landfill sites Exposed dirts, landfill sites, and countries of active digging Cultivated old termlandnext term Agricultural country, harvest Fieldss, fallow old termlandsnext term and vegetable old termlandsnext term Vegetation Deciduous forest, assorted forest old termlands, following term thenars, conifer, chaparral and others Water organic structures River, lasting unfastened H2O, lakes, pools and reservoirs Wetland/lowlands Permanent and seasonal wetlands, low-lying countries, marshy old termland, following term rivulets and gully, swamps Full-size tabular array Position Within Article All orbiter informations were studied utilizing spectral and spacial profiles to determine the digital Numberss ( DNs ) of different LULC classs prior to categorization. Training samples were selected from the mention informations and accessory information ( Table 1 ) . Sixty to seventy preparation sites, runing in size from 286 to 7800 pels, were used to develop the images. Training samples included 5-10 subclasses for each category except for bare soil/landfill. The preparation samples were so refined, renamed, merged, and deleted after rating of the category histogram and statistical parametric quantities. A supervised upper limit likeliness categorization ( MLC ) algorithm, antecedently demonstrated to obtain the best consequences from remotely sensed informations if each category has a Gaussian distribution ( Bolstad A ; Lillesand, 1991 ) , was so applied to each image. However, several of the categories were falsely classified in the supervised categorization of LULC, with certain old termurbannext term colonies being misclassified as landfill sites due to their holding similar spectral features. Similarly, the wetland category was merged with the lowland category as it was non possible to divide them due to similar spectral belongingss, and the wetland/lowland class and cultivated old termlandnext term were besides falsely classified. Post-classification polish was hence used to better the truth of the categorization as it is a simple and effectual method ( Harris A ; Ventura, 1995 ) . In add-on, since the old termurbannext term surface is heterogenous and composed of a complex combination of characteristics ( e.g. edifices, roads, grass, trees, dirt, H2O ) ( Jensen, 2007 ) , assorted pels are a common job when utilizing medium-spatial declaration informations such as Landsat ( Lu A ; Weng, 2005 ) . The job of assorted pels was addressed in several ways. For illustration, thematic information ( e.g. H2O organic structures, flora, and bare dirt ) was foremost extracted from the Landsat informations utilizing the V-S-W index ( Yamagata, Sugita, A ; Yasuoka, 1997 ) , before a rule-based technique utilizing thematic information and GIS informations ( e.g. DEM, municipal maps and H2O organic structures, etc. ) was employed in ERDAS spacial modeller to rectify antecedently misclassified old termlandnext term screen c lasss. Although this rule-based technique greatly improved the MLC categorization, some misclassification between wetland and cultivated old termlandsnext term was still observed, chiefly because of the geographical adjacency of these classs. GIS tools, such as Area of Interest ( AOI ) were so applied to the informations utilizing ocular analysis, mention informations, every bit good as local cognition, to divide and recode these screens so that they more closely reflected their true categories. By using these techniques, the consequence obtained utilizing the supervised algorithm could be well improved. Finally, to cut down the salt-and-pepper consequence, a 3A A-A 3 bulk filter was applied to the classified old termlandnext term screens ( Lillesand A ; Kiefer, 1999 ) . Accuracy appraisal By and large, categorization truth refers to the extent of correspondence between the remotely sensed informations and mention information ( Congalton, 1991 ) . In order to measure the truth of old termlandnext term screen maps extracted from Landsat informations, a sum of 125 graded random pels were generated for the 1975 and 1992 informations and 100 pels for the 2003 old termlandnext term screen map. Accuracy appraisal of the LULC maps was so performed utilizing field informations and the geographical characteristics on old termlandnext term usage maps, high-resolution images, and SOB topographic maps, and the consequences were recorded in a confusion matrix. A non-parametric Kappa trial was besides used to mensurate the categorization truth as it accounts for all the elements in the confusion matrix instead than merely the diagonal elements ( Rosenfield A ; Fitzpatirck-Lins, 1986 ) . The entire truth of the Landsat-derived LULC information was 85.6, 89.6 and 90 % with matching Kappa statistics of 82.7, 87.5 and 87.9 % for MSS, TM and ETM+ , severally, confirming the standard truth of 85-90 % for LULC mapping surveies as recommended by Anderson etA Al. ( 1976 ) . The application of rule-based post-classification polish was found to be effectual and improved truth by 10-12 % . The MSS image had the lowest overall truth, which may be due to its harsh spacial declaration ( Haack, 1987 ) . Yang and Lo ( 2002 ) besides noted that the jobs associated with right sorting assorted pels additions with diminishing image declaration, ensuing in spectral confusion. In this survey, spectral confusion was higher in the MSS image than in the TM/ETM+ images. old termChangenext term sensing This survey employed the post-classification old termchangenext term sensing technique, which is efficient in observing the nature, rate and location of old termchanges, following term and has been successfully used by a figure of research workers in the old termurbannext term environment ( Hardin etA al. , 2007 ) . An overlay process utilizing the GIS was adopted in order to obtain the spacial old termchangesnext term in LULC during three intervals: 1975-1992, 1992-2003 and 1975-2003. Application of this technique resulted in a bipartisan cross-matrix, depicting the chief types of old termchangenext term in the survey country. Cross tabular matter analysis on a pixel-by-pixel footing facilitated the finding of theA measure of transitions from a peculiar old termlandnext term screen category to other old termlandnext term usage classs and their corresponding country over the period evaluated. A new thematic bed incorporating different combinations of â€Å" from-to † old termc hangenext term categories was besides produced for each of the three six-class maps. LULC old termchangesnext term and kineticss of old termurban expansionnext term Spatial forms of LULC old termchangesnext term in the Greater Dhaka country for 1975, 1992 and 2003 are shown in Fig.A 2. In 1975, lowlands, cultivated countries and H2O organic structures were the dominant old termlandnext term usage types, and the way of old termurban expansionnext term ( herein referred to as the built-up class ) was northerly. In 1992, the built-up class replaced most of the H2O organic structures and depressions within the metropolis every bit good as the cultivated old termlandnext term along the peripheral zone. Surveies of historical maps and the available literature suggest that the depressions and H2O organic structures within the metropolis disappeared comparatively rapidly after independency as countries were developed for residential, commercial, academic and concern intents ( Siddiqui etA al. , 2000 ) . Between 1975 and 1992, when route transit from Dhaka to the backwoods was improved by the building of Bridgess over the rivers ( Islam, 1996 ) , old ter murban expansionnext term extended further to the North, north-west and to the West. Consequently, the country of cultivated old termlandnext term and H2O organic structures declined markedly during the period 1975-1992 ( Louis Berger A ; BCL, 2005 ) . In 2003, the forms of LULC old termchangenext term revealed that Dhaka started to spread out in all waies, chiefly at the disbursal of vegetated and wetland/lowland countries. The rate of old termurbannext term invasion ( Fig.A 2 ) on other old termlandnext term utilizations increased significantly following the readying of a new Master Plan in 1995 and the development of substructure ( Siddiqui etA al. , 2000 ) . The building of a span over the Buriganga River accelerated old termurban expansionnext term in the southern and northwesterly waies. The spacial distribution of the exposed soil/landfill class is besides seeable in the maps produced ( Fig.A 2 ) , clearly exemplifying the transmutation of lowland countries to landfills on t he outskirts of Dhaka.

Position Within Article Three sectors, viz. the populace, private, and individual-household sectors, are responsible for all of the old termlandnext term developments in Dhaka. Most of the old development undertakings were undertaken on an ad hoc footing by the populace sector, chiefly in countries that were antecedently used for agribusiness and that were free from flood ; illustrations of such developments include Gulshan Model Town, Banani, Uttara Model Town and Dhanmondi ( Chowdhury, 2003 ) . In recent old ages, belongings development has proliferated in Dhaka, and belongings developers have developed both wetlands and agricultural countries without any consideration of the attendant environmental costs. In add-on, single families have started to develop the peripheral countries ( Islam, 1996 ) . In the fieldwork conducted in this survey, old termlandnext term guess was observed to hold had a pronounced influence on the development of suburban countries. In response to increasing old termlandnext term m onetary values and turning demand for lodging, Lowlandss and agricultural countries in the periphery zone are quickly going built-up by the person and belongings developers. While suburban development is a really complex procedure that is known to be influenced by a assortment of factors, including guess and old termlandnext term monetary values, these factors may non adequately explicate the procedure of suburban development in the survey country. A more elaborate survey is hence required in order to understand the assorted factors act uponing suburban development in the greater Dhaka country. Furthermore, hapless coordination among executive bureaus is besides responsible for the decrease observed in natural resources in the survey country. For illustration, in the Dhaka-Narayangonj-Demra ( DND ) undertaking, despite about 6000A hour angles being set aside for agricultural production in the 1960s, the country has been used by local and migratory people for residential intents sinc e 1990s without any blessing from the governments concerned. Cases such as this illustrate the deficiency of effectual coordination among the organisations involved in the planning and development of Dhaka. Analysis of the LULC old termchangesnext term in Dhaka over clip revealed a considerable addition in the built-up countries over the survey period ; built-up countries increased by 6132A hour angle between 1975 and 1992, which is an norm of more than 360A haA yra?’1. Similarly, built-up countries increased in size by 4422A hour angle from 1992 to 2003, more than 400A haA yra?’1, and the net addition of old termurbannext term countries over the survey period was 10554A hour angle ( Table 3 ) . When compared with other metropoliss in the part, such as Ajmer City in India, the rate of the old termurban expansionnext term in Ajmer City was 29.2A haA yra?’1 over the period 1977-1989 and 32.4A haA yra?’1 from 1989 to 2002 ( Jat, Garg, A ; Khare, 2008 ) . Although urbanisation is by and large related to demographic old termchangenext term and economic growing ( Li, Sato, A ; Zhu, 2003 ) , the nature of old termurban expansionnext term in the survey country may besides be associated with other factors such as topography, old termlandnext term usage, and transit. Close scrutiny of the old termchangenext term sensing statistics revealed that about 6132A hour angle of the urbanised country in Dhaka were antecedently either agricultural countries or H2O organic structures between 1975 and 1992. Conversely, 4422A hour angle of the freshly urbanized countries were antecedently flora or wetlands during the same period. By and large, two factors were observed to hold promoted old termurbannext term growing: ( 1 ) increased economic activity associated with the constitution of economic zones ( e.g. export treating zone ) and ( 2 ) redefinition of the metropolitan country. Between 1975 and 1992, reclassification of old termurbannext term countries every bit good as infrastructural development played a important function in the old termexpansion of urbannext term countries. For case, the nor’-west and southerly old termexpansionnext term of th e metropolis occurred in response to building of a inundation embankment in 1992 ( Fig.A 1 ) and a span on the Buriganga River in 2001. The spacial features of built-up countries have besides been shaped by the building of a figure of transit paths in the same period, as understood from historical map analysis and field visit. The old termexpansionnext term to the E and nor’-east led to the development of unplanned suburbs in the Lowlandss and agricultural countries that were antecedently located in those countries.

Another important old termchangenext term was the diminution in wetlands and flora from 1992 to 2003. In 1992, wetlands and flora occupied 28 % and 13.7 % of the entire survey country, but by 2003, these countries had declined to 21.7 % and 5.5 % , severally. Conversely, built-up countries increased in size by 37.9 % in the period from 1992 to 2003. A little addition in cultivated old termlandnext term ( 6.7 % ) was besides observed in this period. The diminution of flora and wetlands was clearly due to intensification of old termurbannext term development in the greater Dhaka country, peculiarly through the procedure of suburban development. As shown in Table 4, there has been a pronounced old termchangenext term in LULC over the 28-year survey period. Table 4.

Table 4 shows a sum-up of the major LULC transitions, viz. ‘from-to ‘ information, which occurred during the survey period. As indicated, the bulk of old termurban landnext term was acquired by change overing countries that were antecedently agricultural old termland, following term flora, H2O organic structures or low-lying countries, proposing the being of increased force per unit area on natural resources in Greater Dhaka to run into the increasing demand for old termurban land.next term Life-size image ( 247K ) – Opens new window Life-size image ( 247K ) Fig.A 3.A Major old termlandnext term use/conversions in Greater Dhaka ( a ) 1975-1992 ( B ) 1992-2003. Position Within Article The survey revealed that the old termurban expansionnext term in Dhaka has been comparatively rapid and has resulted in widespread environmental debasement. The procedure of old termurban expansionnext term in Dhaka was observed to change markedly over the old ages examined in this survey ; specifically, the metropolis expanded by 6131.9A hour angle during the 17-year period from 1975 to 1992 and 4422.2A hour angle in the 11-year period from 1992 to 2003. Landsat images revealed that old termurban expansionnext term in two periods examined in this survey did non happen equally in all waies ; new developments were observed along the fringe of old termurbannext term countries every bit good as in the countries that had already been urbanized. The rapid gait of urbanisation in Dhaka means that it has non been possible for the municipal authorities to supply basic old termurbannext term comfortss to the population, which has led to a broad scope of environmental jobs. For illustration, old termurbannext term development facilitated by old termlandnext term filling has been shown to hold a negative impact on natural home ground and biodiversity ( [ Alphan, 2003 ] and [ Dewidar, 2002 ] ) . Vulnerability to temblor related jeopardies has besides increased since a major part of Dhaka ‘s recent development has taken topographic point in landfill sites ( Kamal A ; Midorikawa, 2004 ) . In southern Dhaka, landfills have contributed to dirt y pollution, ensuing in reduced flora ( Khatun A ; Hoque, 1994 ) . Uncoordinated urbanisation and the creative activity of landfill sites have intensified the extent of flood in the metropolis during the moisture season ( Alam A ; Rabbani, 2007 ) , which is peculiarly critical in the western parts of Dhaka ( Maathuis, Mannaerts, A ; Khan, 1999 ) . Flood hazard potency has been elevated due to continued infilling of H2O organic structures, wetlands and low-lying countries ( Dewan A ; Yamaguchi, 2008 ) . In add-on, the speed uping growing of slums is impacting the metropolis ‘s physical and human environment. Harmonizing to CUS etA Al. ( 2006 ) , the slum population of Dhaka ( about 37 % of the metropolis ‘s population ) has doubled in a decennary, to make 3.4 million in 2006 from 1.5 million in 1996. The environment of these informal colonies is highly unhygienic as they are in close propinquity to solid waste mopess, unfastened drains and cloacas, embankments, and al ong railroad lines ( Islam, 1999 ) . Consequently, the people populating in slums are highly vulnerable to inundations ( Rashid, 2000 ) and they besides suffer from an acute deficit of drinkable H2O ( Akbar, Minnery, Horen, A ; Smith, 2007 ) . Driving forces analysis LULC old termchanges and urban expansionnext term of Greater Dhaka is governed by a combination of geographical, environmental and socio-economic factors. Although population growing is the primary cause for rapid urbanisation, the part of other causes such as economic development and physical factors besides needs to be assessed. To measure the mechanisms underlying the old termchangesnext term in LULC and subsequent old termurban enlargement, following term we performed a arrested development analysis of built-up countries utilizing selected physical and socio-economic variables ( lift, incline, population and GDP ) , and presented the consequences in Table 5. old termUrbannext term country informations were extracted from one-year BBS statistics since RS informations merely cover three old ages. To analyze the effects of incline and lift on old termurban enlargement, following term average values of incline, and lift of both developed and developing countries in the metropolis wer e calculated from a digital lift theoretical account. Socio-economic informations, such as population and GDP values were obtained from the decadal and annually one-year tabular arraies of the Bangladesh Bureau of Statistics ( Table 1 ) . Table 5.

Position Within Article Census informations indicate that the old termurbannext term population of Dhaka was merely 0.34 million in 1951, increasing to 2.6 million in 1974 with an one-year growing rate of 9.32 % during 1961-1974 ( Islam, 1999 ) . By 1981, the population had reached 3.44 million. The population reached 6.92 million in 1991 and 10.7 million by 2001 ( BBS, 2001 ) . Presently, the population of Dhaka is more than 12 million with an one-year mean growing of 5 % , compared to the national growing of 2.1 % ( Bangladesh Bureau of Statistics ( BBS ) , 2005 and [ The World Bank, 2007 ] ) . The rapid growing of the old termurbannext term population has chiefly resulted from rural-previous termurbannext term migration and estimates show that more than 60 % of people in Dhaka have migrated from rural countries ( Islam, 1991 ) . Intelligibly, this addition in the population had the consequence of increasing force per unit area on the limited resource-base, and significantly contributed to the old termexp ansion of urbannext term countries by glade of natural flora and infilling of low-lying countries. Table 5 clearly shows that old termurban expansionnext term is positively related to population growing. Dhaka ‘s economic development is another factor that has contributed to rapid urbanisation. For illustration, Dhaka ‘s gross domestic merchandise ( GDP ) was about 11,312 million Taka1 in 1976, 129,665 million Taka in 1992 and 162,490 million Taka in 1995. Presently, the GDP of Dhaka is 354,240 million Taka and the metropolis ‘s portion of the national economic system is 19 % ( BBS, 2005 ) . The economic development associated with the roar in ready-made garments since the 1980s has had a important impact on old termexpansionnext term of the metropolis country. This economic activity has besides resulted in a big inflow of rural-previous termurbannext term migrators in the same period ( Islam, 1996 ) . In add-on, Dhaka supports more than 40 % of Bangladesh ‘s industry, farther suggesting that the economic development and industrialisation has led to a higher rate of old termurban expansion.next term The arrested development analysis revealed that GDP exercised positive effects on old termurban land expansionnext term ( Table 5 ) . As in other old termurbannext term centres, the way of old termurban expansionnext term in Dhaka has been extremely influenced by its physical scene, peculiarly its topography. The four major rivers, swamps and depressions within and around the metropolis have ever played a polar function in the development of built-up countries in the metropolis. Urbanization ab initio occurred in the elevated countries that were non affected by inundation. Once all the elevated places had been developed, the lifting demand of old termurban landnext term has been met by the transmutation of low-lying countries, vegetated countries and wetlands. The development of wetlands, for case, has led to a significant loss of natural resources and an addition in habitat debasement. The growing of belongings developers has accelerated invasion of old termurbannext term countries on wetlands and threatens biodiversity. Two geophysical indexs were used in the arrested development analysis ( Table 5 ) and found th at lift has major influence on old termurban expansionnext term while incline has non passed the important trial. Decisions This survey has assessed LULC old termchangesnext term and the kineticss of old termurban expansionnext term in Greater Dhaka, Bangladesh utilizing RS informations in concurrence with socio-economic variables. old termUrban expansionnext term was quantified for the last 28 old ages utilizing the post-classification comparing technique. Greater Dhaka was found to hold experienced rapid old termchangesnext term in LULC, peculiarly in built-up/previous termurbannext term countries. Analysis revealed that old termurbannext term countries increased by 6131A hour angle during 1975-1992 and 4422A hour angle from 1992 to 2003, which resulted in a significant decrease in the country of H2O organic structures, flora, cultivated countries and wetlands/lowland. The dramatic old termexpansion of the urbannext term countries of Dhaka exhibited clear spatio-temporal differences. The transition of H2O organic structures, flora and low-lying countries to old termurban landnext term has caused extende d and varied environmental debasement in the survey country, and the exposure to implosion therapy and the growing of slums have been the chief negative results associated with the rapid old termurbannext term development. old termUrban land expansionnext term has been mostly driven by lift, population growing and economic development. Integrated usage of GIS, RS and socio-economic informations could therefore be efficaciously used to understand the spatial and temporal kineticss of LULC old termchanges.next term The reading and categorization of RS informations were utile for gauging the rate and spacial form of the old termurban expansionnext term in Greater Dhaka of Bangladesh. As dependable and current informations are missing for Bangladesh, the old termlandnext term usage maps produced in this survey will lend to both the development of sustainable old termurban landnext term usage planning determinations and besides for calculating possible hereafter old termchangesnext term in growing forms.

Consumers Perspectives of Mental Health Care Essay

Consumers Perspectives of Mental Health Care - Essay Example This is known as consumer participation and simply refers to participation of consumers (mental illness patients) in the formal or informal development of plans, models of delivery, implementation and appraisal of the entire realm of activities that form mental health care. What really are the benefits and limitations of consumer participation in provision of mental health care? This study seeks to provide the answers to this question and the approach undertaken will be a review of literature focusing on the perspectives of researchers, policy makers, nursing text and relevant consumer accounts. This will be followed by a summary of the findings which will inform the conclusion of the essay. Benefits and Disadvantages of Consumer participation in Mental Healthcare The best way to study this is to establish the perspectives of the various stakeholders in mental healthcare i.e. consumers, carers, researchers, policy makers and health professionals. Timimi (2011, p. 4) weighs the import ance of the psychotherapeutic model adopted by healthcare professionals in terms of positive outcomes and indicates that the outcome is not significantly related to the psychotherapeutic technique selected instead stating that a strong therapeutic alliance with the patient is of primary importance. This is evidence-based as opposed to traditional expertise that places primary importance on mental healthcare under the paradigms of making a diagnosis and implementing treatment. Of particular note is that both biomedical and psychological aspects (for instance use of antidepressants and cognitive behaviour therapy respectively) have been studied and found to bear similar improvements on patients and no significant differences in terms of outcomes regardless of the technique used. One such study involved groups of depression patients treated with CBT, Interpersonal Therapy, antidepressants and placebos and the results indicated significant improvements in all the cases and no significan t differences between the first three versus the placebo group. The underlining factor evidenced by this study was the quality of the relationship between the therapist and the patient as perceived by the patient in the early phases of treatment. The conclusions from such studies and meta-analyses is that the treatment is important in placing the consumer in a given psychological state that is important for their healing especially as evidenced by the fact that such treatments are efficacious across several conditions regardless of diagnosis. The important cross-cutting factor during treatment instead lies in the therapeutic alliance between the patient and the therapist. Hence a good relationship with the prescribing doctor is far more important for a positive response to the treatment implemented than just merely offering the drug (Timimi 2011, p. 5). This study importantly points us to the role of the patient in treatment and thus participation. Griffith and Jenkins (2004, pp. 41 -50) conducted a study to find out the perceived advantages and disadvantages of consumer participation in mental healthcare research and inferred a number of pros and cons based on the views of the various stakeholders. The general view across all groups was an agreement that consumer participation led to improved health outcomes and improved services to the patients. Involving consumers was found to result in consumer empowerment through acknowledgement of their expertise,

Did the psychological support affect the pain of cancer patient and Essay - 1

Did the psychological support affect the pain of cancer patient and cure - Essay Example Cancer patients encounter pain while undergoing their treatment and this may affect them psychologically. Pain is noted to occur to an estimate of 70% of the patients who suffer from advanced cancer. However, research has concluded that there are measures, which can be taken to ensure that the patients manage their pain after treatment. In such cases, the patients are identified as the appraisers of their pain and they are usually encouraged to embark on an active role so that they can effectively manage their pain. A doctor is important in the scenario since they spend time educating the patients and their families on effective measures of minimizing the pain. Cancer patients encounter pain and it prevails based on the emotional context in which it is carried on, Spiegel and Classen (2008). In such cases that involve pain, psychological support is important for individuals especially if the diseases are life threatening. The psychological distress of cancer patients persists based on the clinical courses of illness such as symptom severity, and poor diagnosis, which usually have an effect of psychological welfare. However, the identification of the disease and its treatment are the major steps in the management of psychological distress of the cancer patients. Psychological support is essential on individuals who encounter psychological stress such as cancer patients. Psychological stress happens when individuals suffer from mental and emotional pressure from different diseases. Psychological stress can be because of the daily activities and upset from health conditions. When individuals feel that they cannot manage the effects of cancer, they become distressed. This has been noted to decrease the life span of the cancer patients. In Rosenbaum (2001), it is evident that distress can occur because of poor clinical outcomes. The clinical guidelines enable the doctors to asses the amount of distress on the patients and

According to research, Uniplus has specifically been developed to enhance management of University data, which is for a number of top institutions in Africa such as Egerton University. Uniplus has been of great significance particularly in promoting the business need of many institutions. For instance, at Egerton University, Uniplus was regarded as a very crucial tool for ensuring that the University efficiently managing its revenues. As a result of its use, the university attained higher fee collection since it introduced self-service for students and improved access to information. Financially, the system is needed to ensure that all the institution’s financial data is protected from any unauthorized access. This is a very crucial requirement in maintaining the financial stability of any business organization. The system has also been considered to be of great significance in ensuring the integrity of student performance data. As aforementioned earlier, Uniplus has been of great significance in the day-to-day operations of a University. The development of this project at Egerton University had been scheduled to be conducted within a period of six months. It is important to acknowledge that Uniplus Company was very successful in ensuring that it delivered the project within the allocated time frame. In general, Uniplus, which is an integrated University management system, was finished on schedule (Petrides 60). A significant number of key stakeholders were involved in the development of this project. The top one

3D Graphing Engine Term Paper Example | Topics and Well Written Essays - 10000 words

3D Graphing Engine - Term Paper Example Nowadays geometry engines are called Vertex Shaders since they are programmable and can run so-called (vertex) shader programs to compute and animate the geometry of a scene. Every vertex that needs to be calculated can contain a lot of information, such as an x, y, z coordinate (a 3-dimensional position), texture coordinates, Normal Information (what direction the vertex faces), an identifier (which triangle it belongs to), Skinning parameters, lighting values or just about anything else. However, vertex processing alone does not result in a visible picture.   So as to see all the triangles made up of all the vertices that the vertex shaders have calculated, they need to be colored. Certainly, the invisible object that is a result of the geometry processing needs to be â€Å"wallpapered† so it becomes visible.   To be able to do this, the polygons need to be converted into pixels; this is done during the triangle setup. The pixels are then dealt with in the pixel shaders and pixel pipelines. The color value of a pixel is looked upon a texture; this texture exists in graphics memory as a bitmap that was designed by the 3D artist.   Textures can be available in different resolutions. Higher resolution textures look better; however, use more memory space and more memory bandwidth than lower resolution textures.   For far away objects, this would not only result in wasted processing cycles, but it could also lead to display anomalies. As a result of this, t extures are usually available in different resolutions.   If textures of different resolutions are combined on one object then this is referred to as mip-mapping. This mip-mapping can produce visible borders between the two textures of different resolutions, called mipmap banding.   Moreover, this mipmap banding can be minimized using different filtering techniques. Filtering means that for every pixel to be colored, more than one texel on the texture is looked up and the average is calculated and applied to the pixel.

This brave act is a show of patriotism and his commitment towards accomplishing change in a fundamentalist religious

Mousetrap dump truck and separation system project Essay

Mousetrap dump truck and separation system project - Essay Example The goal of the minor project is establishing innovation and creativity by using a critical way of problem solving. It aims at designing a dump truck –truck used for transportation of loose material. A distinctive dump truck is characterised by an open-box bed hinged at the back, the front can be lifted allowing deposition of the contents on the ground at the delivery site. The core concept of task two is to utilize energy of a mousetrap to make the device mobile for 5 metres in a straight line. The second section of the project is the separation box which is supposed to separate the different sizes of the balls when hit. However, the description of the project is to utilize light, simple, flexible, inexpensive and available materials. There are various materials that the group used to design a lightweight truck model e.g. light carton, disks, BBQ sticks, light fishing line, bottle tops, mouse trap, rubber band and small pieces of cloth hangers. In addition, the group used three materials in designing the separation box: cartoon, BBQ sticks and wooden sticks. Tools involved: glow gun, balloons and tape. In a nutshell, the project should demonstrate innovation of a lightweight truck in the simplest way possible. The concept is to capture energy from a mouse trap to allow it to move for 5minutes along a straight path. The box holding the balls is strateg ically placed high above the body to allow the balls to drop in the separation box. Pieces of cloth hangers are used to improve flexibility. Initially, the project had three possible designs. Numerous factors had to be considered to adopt one as the final plan. Figure 4.1 shows the first design –mouse trap car-the second design consisted of a large coca cola bottle. Figure 4.2 is an illustration of the final design. Before settling for the design in figure 4.2, several tests were directed to eradicate all flaws

Jonathon Swift’s Concern for Ireland Essay Example for Free

Jonathon Swift’s Concern for Ireland Essay In the essay â€Å"A Modest proposal’ Jonathon Swift shows an obvious concern for the conditions of Ireland at that time. He expresses this in a number of ways. Although his proposal may have then and of course in today’s society have seemed completely out of the realm of realistic, he very effectively demonstrated how the proposal would have significantly benefited the overall economy of the country at that time. His concern was expressed first through an obvious concern for the women who were forced to beg for food in order to feed their children, secondly he was concerned about the children growing up and being unable to provide for themselves, and thirdly he showed concern for the lack of sufficient food supply for the country. The proposal he presented was well thought out and designed to solve all three of these problems. First, the proposal would help the women who were unable to care for their children, by providing them with some extra money. He figured how much it would cost to feed a new infant for the first year of life and subtracted that from the amount a woman could be paid for the child when she sold it. This amount would give her enough extra money to buy some food and even clothing for her remaining children. By selling the younger of her children, she is better off not only financially, but she has fewer children to worry about feeding and clothing. This makes her quality of life and that of her remaining children much better. Swift’s second concern for the children, who grow up in poverty remaining in poverty, is easily solved by his proposal. In the proposal, the children would no longer be a drain on the economy and in fact would actually contribute to the overall improvement of society. By being introduced to the food supply of the country, they would benefit a large number of people, which would prove to be a much better way of spending a life than growing up and resorting to begging or stealing in order to continue to survive. The third concern was for the lack of sufficient food supply for the people in the country. His proposal of selling the infants born into poverty as food would greatly increase the amount of available food on the market and thus make it possible for a larger number of people to be sufficiently nourished. In addition to increasing the amount of food available, by eating the poor people’s, or the majority of the population’s children, the population would not grow as quickly and the increased need for food would be greatly lessened. Although most people would find this proposal to be shocking and completely unacceptable, it did reflect his concerns for the condition of the country and proposed a way to solve the problem. If people took the time to look past the shock value of the proposal, it becomes obvious that he was upset with the society and wanted to see change. He goes into great detail on how this proposal would be good for the society and the economy. It would greatly reduce the number of people living in poverty, reduce the amount of people begging on the streets and the crime rate, and help the poor women become more productive members of society. The children would not be forced to grow up and continue the poverty cycle, and the wealthy people in the country would have many more options available for the evening meals and entertaining guests.

Examining the strategic location of South Face Mine

Examining the strategic location of South Face Mine The strategic location of the South Face Mine, owned by Mountain Mining Canada Ltd (MMCL), catches the attention of Can-Do to make an offer for purchasing the mine. If our company successfully acquires it, the combination of better surface logistics and optimal location of new drift mines could provide an annual cost saving of up to $1.5 million for 20 years. However, MMCL has closed the mine and currently been spending on closure and reclamation of it; undoubtedly MMCL would like to transfer those costs to us. The purpose of this memorandum is to determine the walk-away point, which is the highest amount Can-Do would agree to offer in the negotiation with MMCL, with the use of data from the management budget provided by MMCL, the discounted cash flow model and sensitivity tests on various assumptions. Given the data in the MMCL management budget with removal of costs which are not transferred to Can-Do or can be internalized  [1]  , and assuming a 6% interest rate for discounting, the 15% contingency allowance used in MMCL implies an inflation rate of 2.55%. Having studied various assumptions, the sensitivity tests indicate the variance of short-term duration is the most important risk underlying as a 1-year extension of short-term costs reduces the value of acquisition by $6.6 million from $15.5 million to $8.9 million (58% of original value). A 2-year extension further reduces the value by 6.4 million to $2.5 million (16% of original value).  [2]   The recommended walk-away point would be $14 million, a value lower than the net values of acquisition calculated in most sensitivity tests excluding those with respect to short-term duration and estimated cost saving. It also means that an efficient cost control should be performed to avoid an extension of short-term cost and a failure to realize the estimated cost saving. It is also worth noting that there are large discrepancies of cost items between the 2006 and 2005 budgets. A detailed review on financial data is suggested so as to find out any hidden problems or risks. Introduction The purchase of the South Face Mine, currently owned by Mountain Mining Canada Limited (MMCL), can provide Can-Do a very large reduction in operating cost of North Fork Mine, located adjacent to South Face Mine, by an estimated amount up to $1.5 million annually for the next 20 years, attributed to the optimal location of new drift mines and the improved logistics. However, it is expected that MMCL would require us to bear the closure and reclamation costs. Therefore, the net value of the acquisition is the value of cost saving net of the value of those additional costs. By considering the data provided and computing the net value of acquisition, it comes up with the walk-away point, which is critical and crucial to our negotiation with MMCL. The remaining parts of this memorandum explain the determination of the walk-away point. In particular, the purpose of this study is to: Review the financial data provided Do sensitivity tests for assumptions with respect to the closure and reclamation costs Set a reasonable walk-away point Identify other possible risks for the determination of the walk-away point There are different types of costs, including short-term costs which will be incurred within five years and long-term costs which will be incurred during the whole reclamation period. There are also salvage values of equipments remaining on site (i.e. Inventory Disposition), and they will accrue to Can-Do. Moreover, MMCL has included a 15% contingency allowance in its calculation. From the table above, it is clearly observed that large discrepancies exist for most cost items between 2006 and 2005 budget, and this indicates a deficiency of the contingency allowance in 2005 to cover the adverse development of costs estimated from 2005 to 2006. It concerns us about the accuracy and reliability of the predictions. It is suggested a detailed review of financial data as well as other information related to the situation of the mine be conducted in order to discover any potential problems which may put our company at risk. Data Adjustment The data provided is subject to adjustments so as to calculate a more reasonable walk-away point. They include: Removing costs not to be transferred from MMCL to Can-Do (e.g. severance costs) Removing costs which could be realized from internalizing them in Can-Do (e.g. inspection costs) Analysis: Methods Assumptions Contingency Allowance Inflation Rate MMCL has included a 15% contingency allowance in its budget while has not considered the time value of cost items. Assuming the allowance is totally for the inflation, the implied inflation rate that is equivalent to the 15% contingency allowance is found to be 2.55% (using the Excel function à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"goal seekà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚ ), after the data adjustment aforementioned. Sensitivity Tests, Risks Walk-away Point To investigate the risks underlying, sensitivity tests have been performed to examine the uncertainties associated with the assumptions of cash flow projections (all with 0% contingency allowance). Table 3: Sensitivity Tests The table consists of the net value of the acquisition under different combinations of short-term duration, long-term duration, inflation rate and discount rate (Scenario Base and #1-10). From the table, it shows that under most scenarios the value of acquisition is around $14-15 million. Therefore, it would be appropriate and conservative to set $14 million as the walk-away point. In addition, an extra sensitivity test on estimated cost saving are conducted (Scenario #11-12). When compared to Scenario #4, it demonstrates that a 10% decrease in cost saving causes the value of acquisition below $14 million. It implies a strong control is needed to monitor that the realized cost saving is close to the estimated one. As shown in the tables, the short-term duration should be the key risk factor as an increase in it leads to a tremendous decrease in value (by comparing Scenario Base to Scenario #1-2 or Scenario #4 to Scenario #5-6). Can-Do should therefore pay much attention to the extension of short-term cost projections. Conclusions and Recommendations Based upon the modified cost budget and assuming a 6% discount rate, a 15% contingency allowance implies an inflation rate of 2.55%. Also, after a study of various assumptions by sensitivity tests, a walk-away point of $14 million will be sufficient for the acquisition of South Face Mine. However, a few issues have to be highlighted: The large variances between the 2006 and 2005 budget raise concerns of the validity and reliability of the estimated values in the budget. The implied inflation rate of 2.55% is less than the lower bound of inflation rate projected by our economists. The net value of acquisition is very responsive to the duration of short-term costs according to the results of sensitivity tests. The determination of walk-away point is based on the assumption that $1.5 million can be saved annually over 20 years. A slight decrease in it can be enough to cause an overall loss for the acquisition provided that the final purchase price of South Face Mine is close to the walk-away point. For some costs including water treatment operation/maintenance costs and salaries of accountant/environmental person, they may be internalized to a certain extent; yet they are not removed for the determination of walk-away point due to their specialty. This also provides a relatively conservative walk-away point implicitly. It is recommended that a detailed investigation should be carried out to verify the estimated costs in the budget as well as to locate any other problems. It is also proposed that an efficient cost control should be established in order to keep the cost be aligned with the prediction if Can-Do successfully purchases the South Face Mine from MMCL

Racism: Past, Present and Future Essay -- Racial Issues

Prologue While coming up with a topic for this paper, one of my questions dealt with war and cultural groups. I will be the first to admit, Racism was the last thing on my mind. The original question being, â€Å"How does war affect a Social Culture and how does it stand today?† When I started thinking about Cultures that had been so deeply affected by war, one of the first that came to mind were the Japanese in World War II. Then I recalled what one person had told me of their younger days at college, when they were attending school. Their name will remain anonymous; I do not want to make the victim’s name public as it has a very personal nature. They had told me that they had been beaten because they were Japanese. They told me how the group of people, mostly military brats had called them â€Å"Jap†. How they had beaten them up, some restraining them, some throwing punches or much worse. Knowing this person’s experience made me understand why they acted in the manner that they do now. I was shocked initially, the only types of racism that I had heard of and witnessed firsthand was between Whites and African Americans as well as Whites vs. Hispanics. So to hear that another cultural group had been discriminated against in the past, here in the Mountains where I was attending school was an eye opening experience. While I was hearing this story, my mind kept querying, but my mouth remained silent. The question that has pestered me since then and before when witnessing these acts of hatred was â€Å"Why?† My family, especially the female members are very suspicious of Hispanics. One close family member in particular would interrupt rudely while I was teaching my sisters some Spanish phrases I would say them and they would repeat, â€Å"you a... ...e A. Ito.

A Lustful Seduction in To His Coy Mistress :: essays research papers

Seduction most commonly refers to the use of sexual desire in order to persuade an object of affection to change their behavior and meet the desire of their seducer. Andrew Marvell’s ever so passionate poem, â€Å"To His Coy Mistress†, entirely implies the motive to bed a young lady (531). The question raised however, is just what is the attitude of the speaker towards his mistress? Is he acting out of love or lust? And who indeed is the narrator? Could it possibly be Andrew Marvell or an imaginary character that readers can be swept away into the magical enchantment of his lyrical poetry? The foremost indication as to who the narrator may be is in the title. The title is: To Coy His Mistress, not: To Coy My Mistress. For in that case, the word â€Å"my† in the title would portray that Marvell was writing a personal piece, and as it is known, it is not. Perhaps it was Marvell’s intent to satisfy readers by creating an immortal imaginary lover as the protagonist. Therefore, allowing readers to be in awe of his magnificent language and take pleasure in the intentions behind it (531). But just what are those intentions? Is this dominant male’s intention toward the mistress out of love or lust? What the narrator does clearly portray to the audience is that this is a straight forward poem. The male says that, if immortal, he would with pleasure spend all the time on heavens and earth wooing his mistress. But, time is not immortal and nor are they, that he suggest she willingly give herself to him and fulfill his seize the day urgency (531). Using clever literary devices and enchanting imagery the scene is set for him to go forth with his seduction. The persuasive seduction begins in the narrators high remarks of his mistress, An hundred years should go to praise Thine eyes, and on thy forehead gaze, Two hundred to adore each breast, Bust thirty thousand to the rest. An age at least to every part, And the last age should show your heart. (13-18) Such a whimsically beautiful description, could only be written out of love, correct? If he loved her for all of her entirety why would he write the following stanza? For, Lady, you deserve this state, Nor would I love at lower rate. (19-20) It is here that it can begin to be questioned if he truly means all he declares? If he speaks so highly of his mistress why would he not love her at any lower rate and love her for all that she is?

Free Essay on Conrads Heart of Darkness - Human or Humane? :: Heart Darkness essays

Heart of Darkness: Human or Humane?  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Upon reading Heart of Darkness we are immediately struck with the issue of the â€Å"nature of man†, and what it means to be human or humane. To be human means to have a mind, to be living, and function as a primate. To be humane on the other hand means to be tender, compassionate, affectionate, kindhearted, and empathetic. It is often assumed that to be human means to be humane, but as Marlow learned on his excursion through the dark jungle of the Congo, one has nothing to do with the other. Marlow’s first taste of man’s true self as he saw it, began when he saw the six man chain gang, as was referred to in the book, six black men chained together obviously being treated as inferiors, almost as slaves. â€Å"I could see every rib, the joints of their limbs were like knots in a rope;each had an iron collar on his neck, and all were connected together with a chain whose bights swung between them, rhythmically clinking.† (Conrad, pg. 81) Upon seeing this atrocious sight of men being treated as savages, Marlow compares the white men who are leading these chained up men, to devils, by remarking that he had seen devils, but never devils who drove other men like cattle. Men who were no different then themselves, except in the color of their skin. As Marlow continues down the Congo, he begins to reflect upon the river, as the river of truth and reality, because as he transcends down it, his ability to find the truth in any situation grows. With every turn, he learns that mans inhumanity to his own kind is man’s greatest sin. On page 106 Conrad talks about how Marlow felt when he was proceeding towards Kurtz’s station, and he explains that he{Marlow} can feel the past, among the overwhelming realities brought upon by the river, the trees, and the silence. â€Å"There were moments when ones past came back to one, as it will sometimes when you have not a moment to spare to yourself;but it came in the shape of an unrestful and noisy dream,remembered with wonder amongst the overwhelming realities of the strange world of plants,and water, and silence....When you have to attend to things of that sort, to the mere incidents of the surface, the reality- the reality, I tell you-fades.

Returning to School at 29: My Experience Essay

Revised Returning to School Returning to school at this time in my life has been a great challenge, I’m 29 years old and I know I have a long ways to go but I’ve had so many dreams ans aspiration that I wanted to complete before I turn 29. I plan to be done with college at 23 years old but ended up becoming pregnant at 22 years old and a mother at 23 years old so that shifted things for me with returning to school fully committed to my studies. During that time I just stayed working and making me and my son’s life a little easier. So when the time was right to start school again I will be fully ready. I’ve always planned to go to college right after high school which I did at Los Angeles Southwest Community College located in California and then drop out because of family issues and continue to tried to find my way back into college enrolling and dropping out not staying focus on my education. And now I’m at a point where I have to finish this time. Returning to college has had it’s moments like when I started school I was afraid of returning because it has been a while since I’ve been in school over 10 years and returning I felt was going to be challenging for me learning new things and grasping new learning materials and being able to complete assignments especially online which was some what new to me because I’ve never went to school online before and didn’t know what to expect. I remember when I was taking my first course I had got a little overwhelm with the homework assignments being due and adjusting to my new post at the Senior Center and my job as a Security Guard and was at a point of wanting to withdraw form school because it. But after getting some guidance form my admission counselor and how he explained to me how dedicated I was in the beginning before returning to school made me realize how unfortunate it would have been to end my education journey just because I got timid and scared and wanted to stop. But has I look back on it I also realize that I was trying to take the easy way out from fears of returning to school. Since that time me returning to school has been a blessing and has giving me a new purpose to my life meaning for me it’s never to late to go back to college no matter how old you get, and I feel good about myself that I’m accomplishing something I’ve always wanted which is graduating from college and earning my degree. Being in college has always been my dream to finish and actually have a good paying job with benefits for me and my son which has always been a goal of mind to not depend on public assistance for healthcare for my son and to be able to do it on my own. In closing I now appreciate my decision on returning to college again and finally reaching my goal that I’ve always wanted. I will continue to stay encourage and positive through my journey to success.

Competency Statement Essay

To ensure a well-run, purposeful program that is responsive to participants needs. The observation tool that I have provided for Resource V is used to assess the developmental growth in Discovery Preschool children. It is designed to assist teachers in observing, recording and understanding a child’s skills, knowledge, behavior and accomplishments. It allows both parents and teachers to understand what children know and can do. Assessments are completed every fall, winter and spring with parent-teacher conferences to follow. Parents and teachers use these conferences to discuss the assessment. Observation and documentation are important parts of program management because it allows parents and teachers to discuss what children are learning and understanding. There are five areas that are assessed; physical and motor development, social and emotional development, approaches toward learning, language and communication skills and cognition/ general knowledge. Teachers use these assessments to record progress over time. It allows them to see how each child is developing which area, if any, parents and teachers need of focus more on. It also helps teachers provide developmentally appropriate lessons and materials for the children. I ensure that I am accurately and objectively observing and tracking each child’s developmental and learning progress by providing lesson plans that are developmentally appropriate. The assessment is not completed by testing the children. I use my observations and collect classwork don by the children to assess them. I also constantly interact with the children and set up activities that enable the children to demonstrate specific skills and integrate them into everyday activities. For example, while outside with the children, I will play catch with the children. I will observe if they  can catch, throw, and kick a ball. I also ask them various questions throughout the day like, â€Å"What color is the school bus?† or â€Å"Can you tell me what shape this cracker is?† I record all my observations on index cards and place each one in the child’s portfolio. Assessments are a very important tool for both parents and teachers to monitor a child’s know ledge and development. With this documentation parents and teachers can work together to guide children into becoming well- rounded individuals.
