Data Collection and Analysis Essay Example | Topics and Well Written Essays - 1000 words
Data Collection and Analysis - Essay Example Depending on the need, availability of information and expected outputs one or combination of more than one methods for data collection and analysis needs to be adopted. Following are some of the methods for data collection - 1. Primary Research - this method involves collecting information from first hand research done by other individuals / teams / groups and using it to draw inferences with due references to the original research work. 2. Secondary Research - this method involves collecting information which has been derived or inferred from some other primary research work. This may involve articles, secondary research reports, published opinions, etc. among others. 3. Survey - this is a widely known method of data collection by conducting a survey over a sample target population and analyzing the results in order to get first hand information on the research work. 5. Interviews - interviews are another form of collecting information from relevant target population and use the information captured to satisfy the research objectives. Interviews can be structured or unstructured and can be conducted in person or on phone or video conference. 6. Delphi Method - this is a method for collection of expert opinion in the area in which research is being conducted. Experts consulted should be credible and knowledgeable people in the area of the research. For each of the data collection met... However, the above list captures the most commonly used data collection methods. Pros and Cons For each of the data collection methods stated above, there are pros and cons of adopting them in a research project as well as appropriateness for specific type of research projects. Following is a brief discussion on the same - 1. Primary Research - this is a good method of data collection as it provides valuable data points for the research without actually conducting a firsthand research. This method is useful where there are constraints on either time or resources for conducting fully fledged research activities. However, this is still a substitute for actual research. Information available may not exactly match the conditions needed for the research. Hence, there may be compromises or assumptions to be made while using this form of research. This may lead to inaccuracies in research results. 2. Secondary Research - similar to primary research, secondary research may also used in cases of constraints on resources or time. Many times, this form of research is used as a literature review for first step in a research project to provide rough idea on the research topic. This provides important data points which may be useful for designing the actual research, tools used and analysis of data. Again, the disadvantages are that the secondary source information may have inherent inaccuracies introduced while drawing inferences and conclusions from the primary research sources. 3. Survey - this is a popular data collection tool used while conducting business research or market research. The survey results and their analysis provide first hand information directly from the main sources and are not dependent on inferences or

WEEK 8 journal 6500 - Essay Example n for errors to occur during practice, but failure to report these errors could lead a habit that may end up causing serious problems in the future especially when patient safety is concerned. When the nursing students were checking blood sugars, the nurse on the hall wanted them to dry their finger that had been wiped with alcohol by fanning it finger using their hand. According to patient safety, procedure in preventing that would be a wrong technique. The finger should air-dry. The nursing students did it the way the nurse wanted them to even though it was wrong so as not to upset the nurse on the hall. Nursing students need to understand that patient safety comes first, and it is okay to report an error or raise concern if they notice an error being committed by a senior nurse or physician. Having an error-reporting system is one important strategy for improving the healthcare system. Apart from offering safety through reporting and tracing underlying causes, it further offers information about potential future errors and problems (Kim, Kim, Kim, & Kim, 2007). According to Wolf & Hughes, (2008) ââ¬Å"ethical principles of beneficence (doing well) and non-maleficence (preventing harm) are violated when errors are not reported or disclosedâ⬠. The situation I observed at the practicum site mirrors what research has found to be key reasons that lead to medication administration errors, which is a real world problem.

The wide use of CCTV and effects on the Public
The wide use of CCTV and effects on the Public In the year 2000, Philips reviewed the studies that evaluated the effectiveness of closed circuit television (CCTV) in reducing crime, disorder and the fear of crime in a variety of places by using a guiding procedure from Tilleys model (1993a), which focused on the operational mechanisms used in closed circuit television. After his review, he then concluded that CCTV can be very efficient in deterring property crime, but his findings were more restricted to personal crime, public offences and the fear of crime. He also examined the public attitudes towards the use of CCTV in public places. Armitage (2002), in his own review of recent researches into the effectiveness of CCTV on community safety and the practitioners, he observed that CCTV was not always as successful at reducing crime as it was claimed to be. Although he confirmed that CCTV coverage and the governments funding of new systems have increased dramatically over the previous decade, in his findings, he strongly believed that CCTV has been more effective in deterring crime rather than being crime preventive. On the whole, he strongly believed that very little substantial evidence would suggest that CCTV worked. Short and Ditton (1998) noted that researchers in Scotland had concluded that CCTV cameras work to prevent criminality most of the time, unless the offenders were under the influence of alcohol. Obviously, alcohol would hinder proper reasoning and correct decision options. Some CCTV evaluation workers e.g. Gill et al (2005) have interviewed offenders regarding their attitudes towards the installation of CCTV cameras and the possible effects on crime. Although in those studies Gill et al (2005), many offenders felt that CCTV installation has been beneficial to the society, a few people still believe that it was a waste, failing to acknowledge its effectiveness at reducing crime. It was then speculated that offenders would normally wait for the CCTV cameras to move away from their direction before committing the intended crime. It was concluded therefore, that CCTV might have little or no effect in preventing the offenders from committing a crime but rather it would make them aware tha t they were being watched, thereby rendering them to be more careful when committing crimes. 2.2 CCTV and the CCTV Operator. But from the operators perspective according to Smith (2004), limited empirical research has been carried out on the dynamics and social interactions that make up a typical CCTV control rooms operational routine. He believed that the human element has been completely ignored and neglected. His study questioned the accuracy of a central assumption made in most of the written literatures on CCTV (Gill et al 2005). He believed that surveillance cameras were not only controlled and monitored constantly, but are also handled effectively and efficiently by the operators. In order to reduce the effects of tiredness and boredom, the operators often result into extra-curricular activities such as game playing while on duty. Indeed, the findings from the research of Smith (2004) suggested that the operators often felt imprisoned by their job within the confines of the CCTV control room. Based on these findings, he concluded that the human factor has undermined the effectiveness of CCTV surveil lance system. 2.3 CCTV and transport Regarding traffic accidents, Conche and Tight (2006) in their recent research, assessed the potential use for images collected through the increasingly use of CCTV cameras in urban areas as a means of understanding the causes of road traffic accidents and ensuring public safety of all road users. However, they thought that apart from CCTV being used to ensure public safety, it also provided records of accidents which could be used by safety researchers to increase both the quality of life and safety of road users. An area in central Leeds, which was studied showed that an existing CCTV camera network, used for monitoring urban traffic and managing surveillance, has the potential of recording about a quarter of the accidents which occured in the area. This was based on the pattern of past occurrences. Furthermore, majority of the High Streets in the United Kingdom will possibly have more camera set-ups placed in strategic places in order to reduce traffic accidents. The study also con sidered how resourceful the camera and video records could be as a means of collecting contributory factor information on a camera-captured accident. It was expressed as a general belief that the effectiveness of CCTV can only be assessed in terms of how visible each of the factors was likely to appear on video and its relative frequency of occurrence as well as how many crime issues it could resolve. The report concluded that CCTV has a high potential in providing adequate evidences about many of the most commonly occurring factors that contribute to traffic accidents, and in throwing further light on the causes of traffic accidents ( ). 2.4 CCTV and Crime. In the field of environmental criminology, we can not but mention Paul and Patricia Brantingham (2003) who studied extensively the models of crime with theories of the spatial and temporal patterns of human activities to predict the patterns and likelihood of criminal events. By modelling the movement patterns of offenders and the victims, in relation to the distribution and concentration of other people, criminal targets can make it possible to anticipate patterns in the potential displacement of crime from one location to another. The analysis of the movement patterns of criminals utilizing particular crime attractors can provide information on likely crime locations. The behavioural pattern of criminals can be used to predict their activities and the environments of crime, as well as their next-line of actions. Their opinion was that crime prevention and intervention, undertaken in displacement areas, bearing in mind the times and situations that stimulate the occurrence of crime, could have the potential of increasing any crime preventive measure. That article explained how the development of a conceptual model can be used to quantify and predict crime displacement within the concept of time and space. 2.5 Crime Indicators and Attractors The threat of crime to the community is threat to the safety of the society and the sense of security of the residents; and it is also believed to have major impacts on neighbourhood stability, urban and economic development, education, social integration and the perceived quality of life. Today, crime and disorder are often viewed as the main cause of the declining effect of many inner city neighbourhoods. The Fear of crime is sometimes regarded as being detrimental to the society as crime itself. Most crimes can be prevented if the signs are clearly understood and read, and indeed all crimes show crime indicators and signs before they occur. Some of the known crime indicators include: à ¢Ã¢â ¬Ã ¢ Level of crime. à ¢Ã¢â ¬Ã ¢ Fear of crime. à ¢Ã¢â ¬Ã ¢ Crime victims as per cent of population. à ¢Ã¢â ¬Ã ¢ The safety of pedestrians walking alone at night. à ¢Ã¢â ¬Ã ¢ Crime rate. à ¢Ã¢â ¬Ã ¢ Property crimes. à ¢Ã¢â ¬Ã ¢ Percentage that decreased park use due to fear. à ¢Ã¢â ¬Ã ¢ Number of Neighbourhood Watch groups. à ¢Ã¢â ¬Ã ¢ Domestic assault reported per 100,000 populations. (http://www.sustainablemeasures.com/Database/PublicSafety.html) The above are just a few crime indicators; crime indicators are also influenced by location, economic activities, weather conditions and the level of security, etc. According to Spellman (1993), in an economically distressed neighbourhood, the abandoned houses and apartments can become hangouts for thieves, drug dealers, and prostitutes. Inquisitively, does CCTV surveillance recognise these indicators? 2.6 CCTV and the fear of crime. Gafarole (1981), in a paper presented more than twenty years ago supporting Furstenberg (1972), made an observation that has proven to be the understatement of the decade for researchers studying the fear of crime. It was observed thatthe relationship between a crime and its consequences is neither obvious nor simple. His observation was more correct than it was twenty years earlier, despite the fact that the knowledge about the causes and consequences of fear of crime has increased steadily over the years. Every advance that was made, whether by refining concepts, specifying and testing relationships, obtaining more comprehensive data or by some other means, seemed to generate more questions than it answered. After a preliminary discussion of concepts and indicators, a model of the causes and consequences of fear of crime was presented while the components of the model were described in the light of what was already known about the fear of crime. Although the question about the fear of crime has been a major issue with the policy makers and the public (Farrall et al. 2000). The concept of safety can be influenced by a range of different factors so is it with the fear of crime .e.g. Sarno et al., (1999) stated that the presence of CCTV does instil an atmosphere of safety while Ditton (2000) found that one of the positive impact of CCTV is linked to the positive views about CCTV (e.g. Spriggs et al., 2005) Surette (2004) reviewed and discussed the shift to computer enhanced self-monitoring CCTV surveillance systems of public spaces and the social implications. His findings showed the main differences between the first and second generation surveillance i.e. the change from a dumb camera (requiring the human eye for evaluating its images) to a computer-linked camera system which evaluates its own video images. Second generation systems therefore would reduce the human factor in surveillance and address some of the basic concerns associated with the first generation surveillance systems such as data swamping, boredom, voyeurism and profiling. Although additional research is needed to assess CCTV surveillance, the adoption of computer-enhanced CCTV surveillance systems should not be an automatic response to a public space security problem neither should their deployment be decided simply on the availability or cost. In summary, the report has provided a concise overview of the concerns associated with the first generation CCTV surveillance and how the evolution of computer-enhanced CCTV surveillance systems will alter and add to these concerns before a system adoption or installation. 2.7 CCTV Evaluations. Welsh and Farrington (2009) gave a recent review and analysis on the effectiveness of CCTV on crime in public spaces. He evaluated forty-four cases which met the inclusion criteria and the results showed that CCTV caused 16% decrease in crime within the experimental areas when compared with the control areas. The research was motivated by the quest to measure the effectiveness of CCTV schemes in car parks, which caused a 51% decrease in car park crime. CCTV schemes in most other public areas had a small but non-significant impact on crime with a 7% decrease in the city centres and in public houses. Public transport schemes had greater effects with a 23% decrease in total, but these were relatively insignificant. Conclusively, the evaluation showed that CCTV Schemes in the United Kingdom were more effective than other countries such as the USA, based largely on the studies in the car parks. Although Tilley et al (2004) suggested that the use of CCTV increased the risks of being identified and captured as a criminal, Wright and Gibson (1995) added that having the local police and CCTV operators working hand in hand would further help in tracking down suspects and offenders. In the Early years, Ekblom (1986) emphasized that CCTV should be targeted on craved items and pocket-able goods in retail stores to supplement the effort of store detectives. Using the HMV store in Oxford Street as a case study, he discovered that store detectives can cub store theft with the joint effort of CCTV operators. Several studies noted that crime often declined in the months prior to the installation of cameras. After cameras were fully operational, crime might continue to drop for a period as long as two years ( ). Crime would then begin to increase again. As suggested in the literature, this phenomenon is due to publicity or a lack of publicity. The greatest amount of publicity often occurred prior to the installation of the cameras. This was the time when crime levels begin to drop. If CCTV programs were continuously publicized, their effect on crime would remain steady otherwise crime and criminal behaviors would begin to increase as the effect of CCTVs disappeared. According to a brief on the effect of CCTV in 2002 at the Parliament Office of Science and Technology, there was a debate on the changes in recorded crime before and after CCTV camera installation. It was concluded that CCTV was unlikely to reflect crime accurately since not all offences are reported to or recorded by the polic e. Local surveys of crime may provide more accurate measures. 2.8 CCTV and crime displacements. Repetto (1976) speculated that one or more displacements can occur together at the same time while he identified six types of displacements (tactical, situational, spatial, temporal and perpetrator). He defined spatial displacement as the movement of the same crime from one location to another. This is quite different from his definition of tactical displacement when an offender uses a different strategy to commit the same crime. He also defined temporal displacement as when the same offence is committed in the same area but at a different time. This type of displacement is time-oriented. Target displacement was explained when an offender becomes selective in choosing different victims within the same area. Finally, functional displacement operates when the offender changes from a particular crime to another within the same area. Reppetto (1976) then concluded that Displacement refers to the shift of crime either in terms of space, time, or type of offence from the original targets o f crime prevention or interventions. Weisburd et al (2006) argued that crime has the potential to occur when three factors suitable for a crime are present within the available time and space (Cohen and Felson, 1979). However to further expatiate; neglecting the causes of crime such as unemployment and illegal drug would render any intervention ineffective. On the contrary, if the issues of unemployment and drug misuse are addressed, offenders may look elsewhere for a different target area in most cases areas without interventions and thereby leading to crime displacement. Alternatively however, diffusion of benefits to surrounding areas may occur as a result of the intervention. This would depend on the success of the intervention in apprehending offenders. Young et al (2006) researched into crime displacements in Kings cross where views from the streets were used to highlight the impacts of CCTV and policing activities on visible street behaviours. The presence of CCTV surveillance cameras created the fear of being caught on camera thereby contributing to a change in street behaviours by the pedestrians. The data used in this research reflected the cessation of criminal behaviours on the streets. However, the presence of blind spots (areas not accessible to CCTV) are often the areas with high rates of anti-social behaviours. It was concluded that CCTV surveillance cameras do not actually deter crime but rather they are more effective in providing visual evidences in the prosecution of criminals. Such information is handled by law enforcement agencies. Gill and Turbin (1999) studied the effect of CCTV and its effectiveness in a retail store, concluding that this may lower the attitude and vigilance of shop staff where CCTV is seen as th e all- perfect panacea against shop theft or crime, as further buttressed by Beck (2006) on reduction in the degree of vigilance within the store. Nevertheless, the absence of CCTV in local areas was a pre-requisite for crimes such as stealing (Beck, 2006). Gill and Spriggs (2005) wrote a review on the significant crime movements that could be observed clearly from the report on the evaluation of 13 out of the numerous CCTV projects that were put in place by the Crime Reduction Programme (CRP) initiative. The focus was to identify any form of spatial displacement in the schemes that were evaluated. Two techniques, which involved an experimental approach and GIS in assessing any changes in crime trends. The primary aim was to identify any form of displacement and if any could it be as a result of CCTV intervention?. The results showed little proof of displacement. Getis et al (2000) however reviewed the modern techniques of crime analysis with regard to the research and educational challenges outlined by the University Consortium for Geographic Information Science. More attention was devoted to the role that crime analysis currently and potentially played in reducing crime and improving the efficiency of police activities. The main aim w as to stimulate an interest in promoting crime analysis in the advancement of crime mapping and visualization. 2.9 CCTV and Geographical Information System (GIS) Williamson et al. (2000) took an experimental approach and regression analysis as a statistical procedure for analysing temporal crime trends over different periods. Few years later, Ratcliffe (2005) used the nearest neighbour test to identify crime pattern movements between two periods. Both scholars, Williamson et al (2000) and Ratcliffe (2005) used GIS and statistics in their research to provide a powerful tool for understanding the spatial characteristics and the impact of crime reduction measures. Levine (2008) added some other techniques based upon the analysis that could be valuable in hotspot detection. Generally therefore, it appeared that some crime types were predicted more successfully by using the Kernel density which was used for predicting crime hot spots (Chainey et al.,2008a). General comments Note that et al is always written in italics 2. Note that any significant result statement must have the appropriate reference(s) quoted against it Note that person pronouns (I or We) are rarely used in dissertation reports, this is often avoided by employing indirect tenses, e.g. the CCTV coverage zones were studied on two consecutive days should be written instead of I studied the CCTV coverage zones on two consecutive days See under your Introduction: consider whether it was wise to have introduced cctv at all. Has it removed th anxiety of 1980s that originally necessitated cctv era? You can discus your personal opinion from your findings Gather from your literature review the main findings of previous workers that closely resemble your work and identify and relate their own achievements to clearly bring out what you have contributed to the literature of this field. Discuss the appropriateness of the methodology you adopted in comparison with similar others (if any) from your literature review and why you chose it and not the others. You may talk about what you would have better achieved if all the camera spots data were released to you by the Sheffield Information Dept. What else can you discuss from your own intelligence and as a UK licensed driver on cctv traffic offences. Find relevant references that you can use within your results and discussion section to support your findings e.g. on the crime displacements from central /darnall wards 7/9 to wards 6, 13, 2, etc., or deprivation-linked crime environments, etc. Well-done and good luck, my dear; dont look at the work but focus at the Glory-to-God praises on that day and the peace-covenant future awaiting you and your family. 1.3 Closed Circuit Television in Sheffield. The first cameras were installed in 1996 prior to the Euro 96 football competition for which Sheffield was a host city; the cameras were primarily installed to monitor transport links within the city centre rather than to monitor crime scenes. It was not until four years later that more cameras were installed to help prevent and detect crime, in consultation with other services such as the South Yorkshire Police (SYP) and the South Yorkshire Passenger Transport (SPT). They were installed in areas that were potential crime hotspots. It is also clear that the major camera network is extensively installed in the city centre and along the major transport links into the city. Presently, Sheffield City Council has 133 Cameras as at the 1st of July 2010 compared with only 60 cameras in July 2000 indicating an increase of 73 cameras installed in 10 years. In 2001and 2003, 11 Cameras each were installed while in 2002, 26 Cameras were installed at each tram stop; in 2004, only 1 Camera was ins talled in Burn greave while in 2005, 5 Cameras at Eyre Street were installed and in 2006, none was installed. In 2007, 2008 and 2009, a total of 17 cameras (10, 4 and 3 Cameras, respectively) were installed at Millennium Square/ Bus Lane/ Exchange Gateway, Ring Road Urban Traffic Control (UTC), and Granville Square/Bus Lane respectively. Currently in 2010, a few more cameras were installed using funds from the Governments Street Crime Initiative (Devonshire Green/The Wicker), the New Deal for Communities Board (Burn greave), Manor/Castle Development Trust (Park Hill) and Charter Row in the city centre (Single Regeneration Budget, Round 6). And cameras were also installed at Super tram stops from the city centre to Meadowhall terminus, parts of Tinsley and parts of Darnall and the city centre (Sheffield City Council, 2010). More developments are expected in Eyre Street and Sheaf Square. The cost of maintaining and monitoring these cameras are ridiculously high, a summary is detailed below; The total Monitoring Costs = à £474,600.00 The total Maintenance Costs = à £198,037.00 Therefore the maintenance Costs per Camera is à £1,489 per year i.e. each camera costs à £3,568.42 to monitor per year. Despite the high cost of maintenance of CCTV, one of the most sophisticated and digital closed circuit television system in Sheffield is known as Sheffield Wide Image Switching System (SWISS), shown in Fig 2 which is still being used at an advantage in crime reduction. Fig. 2: SWISS IN ACTION IN SHEFFIELD. (Courtesy Sheffield Town Hall). Although the objective of creating SWISS , some of which include the prevention of crime and the provision of evidences against offenders to support crime tracking and prevention and then to help the traffic management or assist in the Automatic Number Plate Recognition initiatives to track vehicles used in criminal activities. However, in view of the cost of maintaining and monitoring these CCTV cameras, incorporated into a system known as SWISS, it would be useful to know if the Big Brother is actually watching the streets. 1.4 Crimes in Sheffield. It was recorded that there was approximately 90% reduction in the number of steel workers employed between 1971 (45,100 workers) and 1993 (4,700 workers). According to Taylor et al (1996), about 10, 000 jobs were lost into the mining industry between 1994 and 1996. With this rapid increase in unemployment, crime rate has increased in certain areas in and around Sheffield , already identified by the SYP force as High Intensity Crime Areas, largely more to the part of the northeast of the city. It is estimated that about 60 000 people live in this area which includes the wards of Manor, Darnall, Brightside, a large area of Burngreave, and parts of Castle, Firth Park, Intake, and Nether Shire. These are, in fact, some of the most deprived wards in England. These wards are known to lack good health, educational awareness, and lack good housing facilities. Notwithstanding the presence of High Intensity Areas, according to Simmons et al. (2003), Sheffield is still believed to be one of the safest areas in the United Kingdom. (National Statistics, 2003). 1.5 Crime Indicators and Attractors. The threat of crime to the community is threat to the safety of the society and the sense of security of the residents; and it is also believed to have major impacts on neighbourhood stability, urban and economic development, education, social integration and the perceived quality of life. Today, crime and disorder are often viewed as the main cause of the declining effect of many inner city neighbourhoods. The Fear of crime is sometimes regarded as being detrimental to the society as crime itself. Most crimes can be prevented if the signs are clearly understood and read and indeed all crimes show crime indicators and signs before they occur. Some of the known crime indicators include: à ¢Ã¢â ¬Ã ¢ Level of crime. à ¢Ã¢â ¬Ã ¢ Fear of crime. à ¢Ã¢â ¬Ã ¢ Crime victims as per cent of population. à ¢Ã¢â ¬Ã ¢ The safety of pedestrians walking alone at night. à ¢Ã¢â ¬Ã ¢ Crime rate. à ¢Ã¢â ¬Ã ¢ Property crimes. à ¢Ã¢â ¬Ã ¢ Percentage that decreased park use due to fear. à ¢Ã¢â ¬Ã ¢ Number of Neighbourhood Watch groups. à ¢Ã¢â ¬Ã ¢ Domestic assault reported per 100,000 populations. (http://www.sustainablemeasures.com/Database/PublicSafety.html) These are just a few crime indicators mentioned above; crime indicators are also influenced by location, economic activities, weather conditions and the level of security, etc. According to Spellman (1993), in an economically distressed neighbourhood, the abandoned houses and apartments can become hangouts for thieves, drug dealers, and prostitutes. Inquisitively, does CCTV surveillance recognise these indicators? 1.6 CCTV Surveillance and the Human Error. However, to start with, does CCTV identify crimes? The long hours spent monitoring CCTV surveillance cameras and reviewing the tapes allow the human error factor to set in. No one seems to be an exception to the vulnerability of the unconscious influences and causes of a tired eye. Fig.3 shows a CCTV operator gazing consciously on a camera at close range. For how long can he gaze without missing the most vital indicator to show a crime as just occurred? Fig. 3: CCTV OPERATOR IN CCTV CONTROL ROOM. (Courtesy, Google Images, 2010). Heather (2005) has explained that the police rarely use the Public CCTV to immediately react to crime but only use it as hard evidence for prosecution and prediction. At the Urban eye expert conference few years ago, it was clear that the UK police officers had other priorities than reacting to CCTV nuisance calls for antisocial behaviours. The huge number of cameras in the UK and the broadcasting of these images on television have made petty crime and antisocial behaviours visible to the public. However because most criminal behaviours were recorded and made live, they became impossible to ignore. However Virilio (1998) explained that visual image is easily forgotten due to the speed of the visual image and the excitement of visual information and acquisition. The use of CCTV by the Police is for evidence collection and to search relevant clues for other crimes committed in the area e.g. suspects arriving and parking their cars or other movements linked to another neighbouring crime. As the police employ CCTV image for prosecution, others are exploring how CCTV can be linked into a predictive or preventive system, which is beyond the established practice of making a video camera visible for deterrence. It is correct to say that mobile CCTV has been very useful in acquiring hot spots images. Though it has been assumed that CCTV displaces crime, it is quite subjective if we could base our facts on mere assumptions (Surveillance-and-society,2010).

Physics of Dipnetting :: physics dip net netting
The Physics of Dip Netting Introduction to Dip Netting Dip netting for salmon in the Copper River is a lot of fun but is also a lot of work.ï ¿ ½ During the summer months salmon will leave their home in the ocean and travel upstream in the Copper River to spawn in its many tributaries.ï ¿ ½ Near the small town of Chitna the Copper River flows through a narrow canyon which greatly increases the speed of the river.ï ¿ ½ This makes it harder for the salmon to swim upstream.ï ¿ ½ However the canyon also creates back eddies near the shore in which the river will actually flow the opposite direction.ï ¿ ½ This is good and bad news for the salmon.ï ¿ ½ Good news because the back eddies are flowing the direction the salmon want to go which makes their trip a lot easier.ï ¿ ½ And bad news (from the salmons point of view of course), it makes the salmon easier to catch because the water is flowing the ideal direction for dip netters as shown in the pictures below. ï ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½ Notice that the back eddie makes it really easy for the dip netter.ï ¿ ½ If there was no back eddie the current would push the net the other direction, which makes dip netting a lot harder. The Physics The physics of dip netting is really quite simple.ï ¿ ½ All a person has to do is find a back eddie with a nice constant current and hold the net underwater in the hopes a salmon will swim into it.ï ¿ ½ The physics then becomes a static equilibrium problem which means that none of the parts are moving in any way either in translation or in rotation (applies only to reference frame used) (Halliday 307).ï ¿ ½ This is illustrated in the picture below. The dip net pole can be compared to a lever of class 1 and the lever principle can be applied, similar to the applet at http://www.walter-fendt.de/ph11e/lever.htm.ï ¿ ½ As stated in the applet from the Contemporary College Physics Simulation Library a lever is in balance if the total left side torque is equal to the total right side torque.ï ¿ ½ Applying that statement to the picture above the person must apply a much greater force on the pole in order to maintain torque equilibrium because the distance from the pivot point is much less than the distance from the force of the current to the pivot point.ï ¿ ½ This can be expressed mathematically. ï ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½ F1D1 = F2D2.ï ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½Ã¯ ¿ ½ ï ¿ ½(where F is each force, and D is the distance each force is from the pivot point)

Middle East Democracy
The idea of installing a full scale democratic government in Iran is something that has undoubtedly crossed the mind of many prominent American politicians, but it has yet to come to fruition because of a number of reasons. For the most part, the promotion of democracy in the Middle East has been a well tried, but failed venture. While many nations in other parts of the world have been especially quick to pick up democracy, those people in Iran and other parts of the Middle East have not been so willing to embrace the idea yet. This has occurred because of the fundamental problems that seem to get lost in translation when western nations try to impose a government on the people in the Middle East. In order for democracy to ever work in Iran or elsewhere in that area of the world, these basic, fundamental differences must be addressed appropriately and ultimately be bridged, so that a common accord can be reached in the best interests of the Iranian people. The primary obstacles to democratic reform in Iran are many and they are tall obstacles. In short, these are basic problems that the people of Iran have with western governments and they are the sort of problems that will keep democracy from coming to Iran at this point. The main thing standing in the way is a difference in religious theory. Though democracy itself purports to support all religions and in effort to promote religious freedom, it is built upon Christian principles and has been a primarily Christian outfit since its inception. When the founding fathers designed the documents that started the nation, they opened up their Bibles for consultation. This is not a fact that is lost on the Iranian people, nor is it lost on the Iranian government. According to NationMaster.com, the statistics on religion in Iran are staggering. According to that website, 98% of the people in Iran are practicing Muslims (NationMaster.com). This in itself is something that creates major issues with democracy and stands as a barrier in the way of every having an active democracy in that country. Of that 98% clip, more than 89% of the Muslims are Shiââ¬â¢a, which creates an added problem. That sect of Islam has been particularly harsh in regards to American policy and democracy. In addition to the problem surrounding religion, there is a problem that exists over control of the country. The controlling party in Iran worked very hard to gain control of the country and they now have a system in place that rewards those who support them and cracks down on those that oppose them. This is done because the country is set up to allow this theocracy to have full and complete control over just about every aspect of the country, including the economy. Since their control is so widespread, there is lots of vested interest in keeping the controlling party in office. If they were to be booted out of office in favor of some new leaders, lots of angry people would be missing out on the benefits that they were used to receiving. According to MapsoftheWorld.com, ââ¬Å"The chief of the state is Supreme Leader Ayatollah Ali Hoseini-Khomeini. The head of the Iran government is President Mahmud Ahmadi-Nejad. The Cabinet consists of Council of Ministers selected by the president with legislative approvalâ⬠(MapsoftheWorld.com). This alone shows the near complete control that the leader of the government has over the country. Though the head of the government is an elected official, there is little to suggest that any elections are conducted in a fair manner. Though the government in Iran is technically considered a democracy because of the fact that they hold elections, one would be hard pressed to find anyone that would consider their system a clear representation of the peopleââ¬â¢s rights. A former American government official has even said in the last month that the democracy effort in Iran is one that will be tough to come by given the current state in the country and Americaââ¬â¢s current relationship with the leaders of that country. In a New York Sun article by Eli Lake, a former presidential assistant is quoted as saying, ââ¬Å"There is not the expertise, there is not the energy for it. The Iran office is worried about the bilateral policy. I think they are not committed to this anymoreâ⬠(Lake). If that quote is any indication, then the democracy effort in Iran has a tough future ahead of it. Overcoming the barriers to democracy will not be easy in Iran, but they are doable with the right policy. One thing to consider is that the religious preferences of the Iranian people are longstanding and they are not likely to change any time in the near future. As such, Western nations must understand that they are going to be dealing with an Islamic nation and they must make allowances for that. Though pure democracy in an American sense will never come off as being an Islamic idea, the proponents of such an Iranian democracy movement must make sure to bridge the gap that exists within perception between the two nations. They must paint democracy in its most positive light to the people of Iran, to make them understand that it is not something to be feared, but rather something to be embraced. If the basic differences in religious preference are going to be conquered, then democracy must appear to them as something that can be incorporated with their Islamic values. Having them adopt Judeo-Christian values is not an option, so if democracy is going to head to Iran, then it must be taken closer to their preferences. As far as power is concerned, this looks like a problem that might not have a solution. Given the fact that the controlling party is not likely to give up any of their stake in the nation regardless of what the American government has to say, a new democratic creation must take this into account. Though there is no way to truly overcome this obstacle, some progress can be made by insuring that the people in control right now understand that they will not be thrown to the dogs in a new democracy program. They will still have the chance to be in power if they are elected fairly by the people of their country. This will not likely be enough to pacify those in power, but that might not be possible in the long run. The primary supporters of democratic reform in Iran are mostly from Western nations and their interest is two fold. For American leaders, the establishment of democracy in Iran helps promote that sort of movement all over the world, and it helps to protect American interests abroad as much as possible. The hope of such a government would ultimately be to get rid of the tyrannical leader that runs that government. When tyrants are eliminated from office, the entire world is better off for it, according to American policy. According to a 2005 New York Times article, the American government is taking great measures to help this happen. They are being helped by leaders in other democratic governments. In an article by Steven R. Weisman, it is stated, ââ¬Å"The Bush administration is expanding efforts to influence Iran's internal politics with aid for opposition and pro-democracy groups abroad and longer broadcasts criticizing the Iranian government, administration officials sayâ⬠(Weisman). This widespread support from the American government has been continued, although it has been reformed since to meet its goals more effectively. The main opponents of democratic reform in Iran are fairly predictable, given the current set of circumstances in that country. The controlling party that runs the government has no interest in changing their ways, as it was the old system that allowed them to gain power and influence. They are the most powerful and influential group standing in the way. Almost as important in this stance against democracy are the religious leaders in Iran. They have a huge measure of control over the population since it is their job to give clarity on religious matters. Under the current theocracy, which is run with a great deal of religious emphasis, they have lots of control and economic swing in the country. This group is probably more important to influence, since it is their interpretation of the Islamic gospel that helps create the prevailing thought of the Iranian people. Given the fact that the deep rooted Christian values in democracy are no secret, it is highly unlikely that the Islamic leaders of Iran are going to relent on their position. In order to influence these political leaders in Iran, there is only one real solution that the American government can use. Since economic sanctions and threats of war do not seem to be working, the U.S. government has to take the initiative to establish some rewards for the leaders if they were to go along with democracy. Economic rewards are very powerful bargaining tools, because the Iranian leaders can get rich if they play their cards right. If the Western governments made it clear that they would provide clear support to any democratic reform, it may influence the Iranian leaders to make some changes to their current working system. Though the basic premise of democracy would indicate that any group should be allowed to jockey for position atop the government, Iran has to be handled somewhat differently. Given the previously mentioned statistics on religion in the country, it would be extremely unwise to allow any anti-Islamic groups to push for control of the nation. It would be unwise for a couple of different reasons. On one hand, they would have no chance of gaining control of the country and would therefore just be stirring the pot. This leads to the second conclusion, which indicates that such pot stirring would only have a negative impact on the reception of democracy. Since democracy has to be brought to Iran in conjunction with Islam, this is a recipe for disaster. One thing that must be considered when a person thinks about American influence in Iran is what kind of broad impact it will have on a number of different people. If America and other western nations were to make a push for democracy in Iran, it might endanger those people in the country that are there in order to do other good in the country. According to an article in the Washington Post by Karl Vick and Daniel Finkel, ââ¬Å"Prominent activists inside Iran say President Bush's plan to spend tens of millions of dollars to promote democracy here is the kind of help they don't need, warning that mere announcement of the U.S. program endangers human rights advocates by tainting them as American agentsâ⬠(Vick, Finkel). This means that the mere announcement of any such effort would immediately put people in danger within Iran. This is not important on the basis that it would endanger a few human rights workers. It is important on the basis that if such widespread distaste for America exists among the people, then there is virtually no chance of American-led policy to stick in the country. Other factors must be considered, though. If America wants to keep Iran from becoming the next big Middle Eastern super power, then something must be a done. While the foreign policy of the United States should not include the right and prompting to go to war on a whim, it should help protect American interests. The United States has spent countless dollars and thousands of lives in establishing a semblance of normalcy in Iraq. According to some people, any action in Iran would destroy the work already done in its neighboring country. A United Press International article by Claude Salhani reads, ââ¬Å"However, any attack on Iran would reverse any gains made in Iraq. This point was repeated to the U.S. secretary of defense by various Gulf officialsâ⬠(Salhani). The government of the United States has to be very careful in this case, as they are playing with fire, to an extent. The only way that the American government should put dollars and effort forward in an attempt to reform Iran is if they have a clear idea of how to get things done. Any plan that is devoid of such a clear objective would fail miserably. The objectives must be to help end tyranny in Iran and to protect American interests on a security level. They must be handled diplomatically, as a military conflict in Iran at this time would be a recipe for disaster, given the nuclear implications that exist. A Steven Erlanger article in the New York Times indicates the thinking of Israel on the matter of nuclear weapons in Iran. In his article, Erlanger writes, ââ¬Å"Israel thinks that an American National Intelligence Estimate about Iran's nuclear weapons program, published in an unclassified version last week, is unduly optimistic and focuses too narrowly on the last stage of weapons development ââ¬â the fashioning of a bomb out of highly enriched uraniumâ⬠(Erlanger). This means that some uncertainty exists over whether or not the country has any real, threatening weapons. If they were to possess advanced nuclear capability, then America and other nations must make sure to tread very lightly in enemy territory. Works Cited Erlanger, Steven. New York Times.

The Rainforest
Rainforest's are a tropical forest that are found around the earths equator. The rainforest is found in Idonesia, South America and west and central Africa. The average temperatures are about 25-30 degrees. The rainforests are important because they provide homes for animals, plants and human, they also stabilise the climate by absorbing carbon dioxide. However in the 21st century they are under threat because of logging for timber, mining, road building, pasture for cattle ranching, crops and settlements. This essay will be researching 4 statements on the valuable resources that the rainforest offers and if sustainable devlopment can truly be introduced in the rainforest. ââ¬Å"The rainforest is a valuable resource and its preservation is important to us allâ⬠The rainforest provides homes for about 70 million people, it also provides habitats for over 50% of the earths species of plants and animals. It also contains many plants which could provide new drugs and medicines in the furture e.g. Curae is a poison on Waorani hunting arrows which we also use as a relaxant in modern surgery. The rainforest also stablise's the climate by absorbing carbon dioxide this also helps reduce the rate of global warming and they reduce soil erosion by intercepting the rainfall and also keep water courses free from sediment. If deforestation was to continue millions of animals and plants would lose their habitats and possibly become extinct. Thousands of indigenous people of the rainforest would lose their homes and their way of life. We would also lose many cures for dieases and medicines that we could discover in the furture. Lots of damage to the climate and the enviorment could also mean that global warming would increase at a quicker rate. ââ¬Å"The indigneous people of the rainforest respond positively to the challenges of their natural enviorment and act as stewards of the forestâ⬠Their are about 250 million indigenous people and about 5 thousand tribes, two of the tribes are Maorani and Kayapo. They live of the forest by using it to make food medicines and products to sell to make money such as brazil nuts. The indigenous people should be stewards of the forest because they live there, it is their home and they lived there for thousands of years which gives them historical rights to the Rainforest, they also want to protect it from damage and the dieases people have brought in. ââ¬Å"There are some people who wish to exploit the rainforest. Explotation of the forest has positive and negative effects.â⬠Explotation of the rainforest can be negative and positive. Cattle ranching is positive because it helps feed the countrys own people and they can sell it to other countrys to make money, the negative side of it is the grass that grows in rainforest area is of poor quality and cattle do not thrive, also milk yields tend to be low and after a few years the land is no good. Logging is good because it gets us useful materials such as mahogany, sapele and lauan, which grow no where else in the world, the negative of this is one hactare of rainforest is cut down just to log one mahogany tree. The positive of mining is that we get many good and useful metals such as gold, silver, aluminium, iron ore, copper and zinc. The negative of it is many trees get chopped down and mercury which is used in gold mining causes contamination. Road building does not cause much deforestation but the settlements in its way do get destroyed, it does do a lot of good it allows people to get in and out of the forest easily and quickly. Oil exploration does alot of damage to the forest, many trees have to be chopped down for the pipe lines and disturbs the wild life. The toxic chemicals do alot of contamination to the rivers and soil. the positive of it is oil is a very useful resource. Farming is one of the largest causes of forest loss. Huge plantations of banana and African oil palm now stand where rainforest once did, often farmers form other places who do not the farming techniques needed for forest enviorments, which means the soil soon becomes depleted, requiring further forest to be cleared. Hydro-electric dams are enviormentally friendly but to build them a lot of forest is destroyed. The positive of all these things is that it means money for the devloping countries and also opens up lots of jobs for the local people. The negative of these things is that they all do at least some damage to the rainforest. ââ¬Å"A balance can be achieved between sustained devlopment and conservation of the rainforestâ⬠National park areas would make money from visiting tourists and would protect an area of the rainforest. Brazil nut trade is a good way for the indigenous people to make money, they pick them with out harming the trees and then turn them into an oil, which they sell to the body shop and the body shop turns the oil into a conditioner. Rubber tapping is where a liquid called latex is extrated from plantation trees, the latex is then processed to make a solid material called rubber, it is then sold and exported to other countrys. Enviormentally friendly logging is where only the trees that they want are cut down with out damaging the surrounding enviornment. The definition of eco tourism is ââ¬Å"responsible travel to natural areas that conserves the environment and improves the well-being of local people.â⬠there are seven principles to this: * Minimize impact * Build environmental and cultural awareness and respect * Provide positive experiences for both visitors and hosts * Provide direct financial benefits for conservation * Provide financial benefits and empowerment for local people * Raise sensitivity to host countries' political, environmental, and social climate * Support international human rights and labor agreements Eco tourism is something everybody can participate in.

Positive Degree of Adjectives and Adverbs in English
Positive Degree of Adjectives and Adverbs in English In Englishà grammar, the positive degree is the basic, uncompared form of an adjective or adverb, as opposed to either the comparative or superlative. Also called the base formà or the absolute degree. The concept of positive degree in the English language is one of the simplest to grasp. à For example, in the phrase the big prize, the adjective big is in the positive degree (the form that appears in a dictionary). The comparative form of big is bigger; the superlative form is biggest. C. Edward Good notes that the raw adjectivein its positive statemerely describes the noun modified; it doesnt care about how this particular person or thing stacks up against other members of the same noun class (Whose Grammar Book Is This Anyway? 2002) Etymology From the Latin, to place Examples and Observations Yertle the turtle was king of the pond.A nice little pond. It was clean. It was neat.The water was warm. There was plenty to eat.(Dr. Seuss,à Yertle the Turtle. Random House, 1958)There were three nice, fat little pigs.à The first wasà small, the second was smaller, and the third was the smallest of all.(Howard Pyle, The Three Little Pigs and the Ogre. The Wonder Clock, 1988)It was a large heart with lots of hearts growing smaller inside, and piercing from the outside rim to the smallest heart was an arrow.(Maya Angelou,à I Know Why the Caged Bird Sings. Random House, 1969)Fewà things are harder to put up with than the annoyance of aà goodà example.(Mark Twain,à Puddnhead Wilson, 1894)The tone of the trombone is allied in quality to that of the French horn. It also possesses a noble andà majestic sound, one that is even larger and rounder than the horns tone.(Aaron Copland,à What to Listen For in Music, 1939)Humanity has advanced, when it has advanced, not because it has beenà sober, responsible, andà cautious, but because it has beenà playful, rebellious, andà immature.(Tom Robbins, Still Life with Woodpecker. Random House, 1980) Marys parentsà traveled farà to trade and to search for food.(Shannon Lowry, Natives of the Far North. Stackpole, 1994)The inspirational value of the space program is probably of far greater importance to education than any input of dollars.(Arthur C. Clarke,à Profiles of the Future: An Inquiry into the Limits of the Possible,1962) Three Degrees to Consider à Adjectives change form to show degree of comparison. There areà three degrees of comparison: positive, comparative, and superlative. . . .Theà positive degreeà describes one item or one group of items. The positive form is the form used in dictionary definitions. (A.C. Krizan et al., Business Communication, 8th ed. South-Western, Cengage, 2011)Adjectives change form or add more or most to show comparison. Almost all one-syllable adjectives- as well as many of two syllables- add er to their positive (noncomparative) form to show comparison with one thing; this form is called the comparative form. To showà comparisonà with two or more things, these adjectives add est; this is called the superlative form. Some two-syllable adjectives and almost all adjectives with three or more syllables show comparison with one item by placing the word more before the adjective; they show comparison with two or more items by placing the word most before the adjective.(Peder Jones and Jay Farness, College Writing Skills, 5th ed. Collegiate Press, 2002) Pronunciation: POZ-i-tiv
