Fall in Elderly

1 The Role of Tai Chi Exercise in Promoting Health Benefits for Older Persons Fuzhong Li, Ph. D. , Oregon Research Institute Tai Chi, or Taijiquan to be exact, originated in China about 300 hundreds years ago (China Sports, 1980) and began as a form of martial arts like boxing. It has continued to evolve from being originally used as a combative and self-defense form to a health-enhancing exercise, practiced by individuals of all ages to maintain health and prevent disease. As an alternative exercise, Tai Chi has drawn increasing research interest, with accumulating evidence showing the therapeutic value of Tai Chi to overall health and well-being. The goal of this paper is to summarize current research findings with a particular focus on geriatric populations, discuss findings with respect to their practical implications, and highlight future research directions. Overview of Research Findings A number of excellent review articles exist showing evidence that Tai Chi generates various health benefits for individuals of varying age groups and patient populations (Fasko & Grueninger, 2001; Lan, Lai, & Chen, 2002; Li, Hong, & Chan, 2001; Verhagen, Immink, va der Meulen et al. , 2004; Wang, Collet, & Lau, 2004; Wayne, Krebs, Wolf, et al. , 2004; Wu, 2002). Without overdue redundancy, the following provides a summary review of research studies that involve randomized controlled trials (RCTs) although results from non-RCTs are reported in the absence of RCTs. With aging processes, declines in physical and mental status in older adults often result in balance control impairments, functional limitations in locomotor activities, disability in particular activities, and decreased quality of life. Therefore, this review also focuses on health outcomes that have been shown to be clinically most relevant to this population. These include balance and falls, musculoskeletal conditions, sleep quality, cardiovascular and respiratory function, and psychosocial wellbeing. Balance Control, Falls, and Fear of Falling Falls are significant public health problem among older adults (Murphy, 2000; Stevens, 2005), making it a major threat to the independence and quality of life of older adults, as well as imposing significant burden to individuals, society, and national health systems (National Action Plan, 2005). As a stand-alone exercise intervention, Tai Chi has been shown to reduce the risk for falls. Wolf and his colleagues (1996) conducted the very first randomized controlled trial comparing the efficacy of two methods of exercise on falls. Community living healthy adults were randomized to one of three groups: Tai Chi training; computerized balance training; and an attention control. Results of this 15-week trial showed that Tai Chi participants experienced significant reductions (by about 47%) in falls compared to the exercise control participants. In a follow-up 48-week RCT, Wolf et al (2003) evaluated Tai Chi with older adults who were less robust (that is, transitioning to frailty). No significant between-experimental group reductions in falls were observed. However, by analyzing fall data from month four through month twelve, the study showed a significantly reduced risk of falls in the Tai chi group compared with the exercise control group. In an independent study, Li et al. (2005) confirmed the general findings of those reported by Wolf and his colleagues. These researchers reported that, at the end of a 6-month Tai Chi intervention, significantly fewer falls (38 versus 73), lower proportions of fallers (28% versus 46%), and injurious falls (7% versus 18%) were observed in the Tai Chi condition, compared to a low-impact stretching control condition. Overall, the risk of multiple falls in the Tai Chi group was 55% lower than that of the stretching controls. In addition, compared to stretching control participants, Tai Chi participants showed significant improvements in measures of functional balance, physical performance, and reduced fear of falling. Of equal importance, intervention gains in these measures were maintained at a 6-month postintervention follow-up in the Tai Chi group (Li et al. 2004). Musculoskeletal Conditions Evidence to date indicates that Tai Chi training preserves or even increases lower-extremity muscle strength. Wolfson et al. (1996) showed that 6 months of Tai Chi training (following their primary interventions) did not improve lower-extremity muscle strength, compared to an exercise control group. However, their data did indicate that Tai Chi training preserved lowerextremity strength gains developed by the intervention. In a 20-week pilot study, Christou et al. 2003) showed that, compared to those in the control condition, Tai Chi participants significantly improved knee extensor strength and force control among older adults. Tai Chi also appears to be safe and beneficial for patients with rheumatoid arthritis. In a randomized trial among older women with osteoarthritis, Song et al (2003) showed a 12-week Tai Chi program resulted in significant improvements in pain and stiffness in joint s, balance, and abdominal strength, and fewer reported perceived difficulties in physical functioning, compared to those of control subjects. Another randomized trial, Hartman et al (2000) showed that a 12week program significantly improved osteoarthritis symptoms such as fatigue, arthritis selfefficacy, feelings of tension, and satisfaction with general health status. More recent evidence points to the potential of Tai Chi as a weight-bearing exercise for retarding bone loss in older women. In a 12-month randomized trial, Chan et al (2004) tested the hypothesis that Tai Chi may retard bone loss in early postmenopausal women. At the end of the trial, bone mineral density (BMD) measurements revealed a general bone loss in both Tai Chi and control subjects at all measured skeletal sites, but with a slower rate in the Tai Chi group. Although the BMD findings were equivocal, the findings lend some support for the potential of Tai Chi to retard bone loss. Cardiovascular and Respiratory Function Although numerous studies have evaluated the effects of Tai Chi on cardiovascular and respiratory function, no RCTs have been reported that involve older adults. A number of Taiwanbased observational studies have shown improvements in cardiorespiratory function resulting from Tai Chi. For example, among long-term older adults practicing Tai Chi, significantly better cardiorespiratory function has been reported (Lai, Lan, Wong, & Teng, 1995; Lan, Lai, Chen, & Wong, 1998), and improvements were also observed among coronary artery bypass surgery patients deemed to be at low risk during their participation in a Tai Chi exercise program (Lan, Chen, Lai, & Wong, 1999). Hypertension Tai Chi is a low-impact activity with self-paced and fluid movements, making it appropriate as a means to reduce blood pressure in people with hypertension. Two intervention trials compared the effects of Tai Chi and aerobic exercise on blood pressure – a surrogate for hypertension. An earlier study by Channer et al (1996) showed that over 11 sessions of exercise, both Tai Chi and aerobic exercise were associated with reductions in systolic blood pressure; Tai Chi was also associated with reductions in diastolic blood pressure in a sample of patients recovering from acute myocardial infraction. In a different study by Young et al. (1999), physically inactive older women with systolic blood pressure 130-159 mmHg and diastolic blood pressure > 95 mmHg were randomized to a 12-week moderate-intensity aerobic exercise program or a Tai Chi program of light activity. At the end of the intervention, the Tai Chi group decreased 7. 0 mmHg of systolic and 2. 4 mmHg of diastolic blood pressure. No significant differences were observed between the two exercise activities. The authored concluded that programs of moderate intensity aerobic exercise and light exercise may have similar effects on blood pressure in previously sedentary older individuals. Quality of Sleep Self-reported sleep complaints are common among older adults (Neubauer, 1999) and it is estimated that up to 50% of elderly persons complain about their sleep (Alessi, 2000). Li et al. (2003) conducted a six-month intervention trial to examine the impact of a simpler Tai Chi program on improving quality of sleep and reducing daytime sleepiness among older adults reporting moderate sleep complaints. Participants were randomly assigned to a Tai Chi group or an exercise control group. At the end of the study, Tai Chi participants reported significant improvements in several sleep-quality related measures in comparison to the control participants; with reduced sleep latency (by about 18 minutes per night) and daytime sleepiness, and improved sleep duration (by about 48 minutes per night). The study provided preliminary evidence linking the benefits of Tai Chi exercise to improved quality of sleep and reduced daytime sleepiness in older adults. Psychosocial Wellbeing and Confidence Li and his colleagues (2001a,b,c,d, 2002a, 2002b) provided a series of reports examining the extent to which Tai Chi enhanced older adults’ multidimensional psychological well-being and health-related quality of life indicators. In a 6-month randomized controlled trial, healthy older adults were randomly assigned to either a control condition or Tai Chi. Results indicated that Tai Chi participants reported higher levels of health perceptions, life satisfaction, positive affect, and well-being, and lower levels of depression, negative affect, and psychological distress (Li et al. 2001a). Participants also showed higher levels of both domain-specific physical self-esteem (Li et al. , 2002b) and exercise self-efficacy relevant to movement confidence (Li et al. , 2001c). Change in the level of movement self-efficacy was found to be significantly related to change in physical functioning (Li et al. , 2001b). Similar profiles have been reported by other researchers (Kutner, Barnhart, Wolf, McNeely, & Xu 1997) in that Tai Chi practice resulted in improved well-being, increased alertness, relaxation, better mental outlook, achievement, and greater confidence. Practical Implications The previous summary and review makes it clear that Tai Chi provides multiple health and therapeutic benefits for older adults. Thus, some discussion of practical implications appears to be in order. Fall Prevention Falls can result in devastating consequences for older adults. Accumulating evidence to date suggest that Tai Chi may be an effective means of improving deficits in balance and functional limitations, and therefore, may serve as a therapeutic exercise for balance and strength, and consequently, reduce the risk of falling and the rate of falls in older adults. Tai Chi may also be considered as an exercise modality that generates confidence building to counteract fear of falling, a common psychological symptom of falls among community adults. However, Tai Chi does not provide a quick fix for the fall problem. Most research in this area has focused on short-term results. Findings from current RCTs show that, however, a minimum of three months training is required before clinically meaningful reductions in risks of falling can be achieved, suggesting the need for long-term, sustained, and frequent practice, perhaps on a day-to-day basis, to obtain the full benefit. Tai Chi as an Alternative, Therapeutic Exercise Tai Chi has been recommended for treating many chronic conditions. For example, as a lowimpact, low-intensity alternative exercise therapy, Tai Chi has also been proposed as a potential option for the management of osteoarthritis (Lumsden, Baccala & Aartire, 1998). As a fall prevention activity, Tai Chi has emerged as an appropriate stand-alone balance training program for older adults to improve balance and prevent falls (JAGS, 2001). But even though Tai Chi appears to have numerous benefits to participants, it is still too early for physicians to begin prescribing Tai Chi as a remedy for chronic health problems because many of the studies have design limitations (Wang et al. , 2004), making it difficult to generalize results to broader patient populations. In this regard, patients with chronic health problems need to take precautions before beginning a Tai Chi program, because for some people Tai Chi could worsen medical conditions or problems/ symptoms. In some cases, appropriate odifications may be needed to better accommodate patients’ special needs or physical limitations. Program Costs, Logistics, and Protocols One of the most desirable aspects of Tai Chi is its absence of a need for high technology in promoting health. Tai Chi is easily distinguished from highly technical computerized balance training protocols, and may be just as successful in achieving fall reduction or balance improvement objectiv es; certainly, Tai Chi is more practical. Tai Chi is a low-cost exercise regimen because special equipment or facilities are not needed (Lan et al. 2002; Li et al. , 2003). Li et al (2001b) reported that, in a 6-month RCT, the total direct cost was approximately $9000 (an average of $3. 50 per person per session). Others (Wilson & Datta, 2001) have reported that a twice weekly Tai Chi program was cost-saving whether direct benefits alone (hip fracture costs averted) or direct plus indirect benefits were considered, with a total net cost savings of $1274. 43 per person per year. When considering direct cots only, the net cost savings were $8. 04 per participant per year. Lower costs ensure that more community-dwelling older adults have 5 sufficient access to programs, and abundant opportunities to participate, which is likely to have profound public health implications. While costs of learning Tai Chi are potentially low, one should not underestimate the fact that Tai Chi is a complex system of movements that, when performed, requires body awareness, motor coordination, and agility; features that could make Tai Chi less immediately deliverable to community adults (Li et al. 2003). Therefore, even though the benefits of regular Tai Chi exercise are quite clear, the challenge of maximizing the opportunity for older persons remains because certain movements may be beyond the capabilities of some elderly individuals or others with disabilities. Thus, there is a need to modify existing Tai Chi protocols to develop forms that are simple, easy to perform, and enjoyable (Chen, 2002; Li et al. , 2003; Wolf et al. , 1997), and that do not require years of sust ained practice to master. Tai Chi Styles There are several styles of Tai Chi, some of which are historic/traditional and some of which are of more recent origin. The earliest known form can be traced to the Chen style and evolved and progressed into multiple styles or schools. Currently, there are five main schools of Tai Chi (People’s Sports, 1996), each named after the style’s founding family: (a) Chen, (b) Yang, (c) Sun, (d) Wu (Jian Qian), and (e) Wu (He Qin). Each style has a characteristic protocol that differs from other styles in the postures or forms included, the order in which they appear, the pace at which movements are executed, and the level of difficulty. For example, one significant difference between Chen and Yang styles is that Yang style movements are relaxed and evenly paced. By comparison, the Chen style is characterized by alternating slow movements with quick and vigorous movements, including restrained and controlled actions/motions, reflecting its martial origin. Yang Style Tai Chi, which evolved from the Chen school, is probably the most popular Tai Chi style being practiced today (e. g. , Swaim, 1999; Yu & Johnson, 1999). Yang style movements are performed in a relaxed and flowing manner, with the trunk erect as the axis of all movements, making it immediately suitable for elderly, frail, or disabled populations. To date, the Yang style, with its variations, has been used as an therapeutic exercise modality in most medical and behavioral research. Although there are multiple versions of the Yang style (both short and long, covering 24-, 48-, 88-, and 108-Forms) (China National Sports Commission, 1983), the 24-Form, based on the most popular sequences of the Yang Chengfu school (China Sports, 1980; People Sports, 1996), is the most readily adaptable to the lifestyles and living situations of older adult populations. It is also the most accommodating, requiring minimal demands of personal strength, speed, endurance, flexibility, and motor skills for participation. Is Tai Chi Ready for Dissemination? In a 2001 joint communique on the prevention of falls among the elderly, the American Geriatrics Society, the British Geriatrics Society, and the American Academy of Orthopedic Surgeons suggested that Tai Chi â€Å"†¦is a promising type of exercise, although it requires further evaluation before it can be recommended as the preferred balance training† (JAGS, 2001). Since the publication of this joint communique, one large successful RCTs has been published (Li et al. , 2005) providing supporting evidence documented by Wolf et al. ’s earlier work (1996). As a result of these studies, we should be asking questions about how we can most effectively translate and disseminate the Tai Chi program. With this accumulated evidence, the time is near 6 for Tai Chi to be recommended as a preferred exercise for balance training and be routinely prescribed for older patients at risk for falling following appropriate screening. Future Research Directions Despite the increasing interest in studying the effectiveness of Tai Chi training and the resulting evidence of health benefits, there remain areas that require further research. We highlight a few of these. A Need to Understand the Mechanisms of the Benefits Shown Although findings from Tai Chi intervention studies are important from a public health perspective, they provide little information relative to the underlying mechanisms that may produce such effects. In this regard, little attention has been given considering intervention/treatment mediators or moderators that help identify causal pathways between treatment and outcome, and possible mechanisms through which a treatment might achieve its effects. For example, although Tai Chi has repeatedly been shown to improve balance, possible mechanisms by which Tai Chi improves this outcome, and prevent subsequent falls, remains to be determined. Future studies should target specifically older adults with balance impairments, and consider integrated laboratory and/or clinical measures that may help identify specific mechanisms whereby Tai Chi can remedy balance disorders. A Need to Better Understand Effects to Patients with Chronic Conditions A review by Wang et al. (2004) concluded that there is insufficient information to recommend Tai Chi to patients with chronic conditions. For example, the impact of Tai Chi on several important geriatric syndromes such as frailty, dementia, and sarcopenia are worthy of study or further research. Large clinical trials, involving populations with specific medical conditions are needed before health professionals can recommend Tai Chi exercise as an alternative to the more conventional exercise forms that have been shown to produce health benefits. The potential application of Tai Chi to important geriatric issues yet to be studied include: obesity, osteoporosis, diabetes, neurological disorders (e. g. , Parkinson’s disease; peripheral neuropathy). A Need to Study Long-Term Effects Tai Chi intervention studies are typically conducted with a short-duration (e. g. , 3 months, 6 months). Long-term effects of Tai Chi training (e. g. , 12 months up to 2 or 3 years) are largely undetermined. Therefore, questions such as how long the established effects on clinical endpoints will sustain over a longer period of time remains to be determined. Certain outcomes may take a longer time to show an effect. Reductions in falls are a good example. Other outcomes such as BMD, may require up to one year to demonstrate clinically meaningful change because Tai Chi is a low-impact activity. Also, research from the general exercise literature indicates that people who participate in an exercise program often fall back into their older inactive lifestyle after a program ends (van der Bij, Laurant, & Wensing, 2002). Although anecdotal evidence suggest that participants remained active upon program termination (Li et al. , 2001b; Wolf et al. , 1996), critical issues such as getting people to initiate and maintain the Tai Chi activity over a long-term need to be addressed. A Need to Evaluate Programs That Can Be Disseminated in Broader Community Settings Ultimately, for the results of the research-based evidence to have greater public health impact they must be diffused and made accessible to the community. However, it remains unclear whether the general community can readily implement or adopt these Tai Chi training protocols despite evidence of their tested efficacy. To date, there is no widespread, nationally available Tai Chi-based falls prevention program that is based on the effectiveness of scientifically controlled studies. In this regard, program evaluation research is needed to translate effective interventions into a program that is implementable in community settings. The Oregon Research Institute is currently conducting a project to move effective interventions into community practice. The project has identified randomized controlled studies of scientifically-based effective Tai Chi fall interventions and focuses on issues related to â€Å"reach† (i. e. , proportion of older adults who are willing to participate in a given Tai Chi program initiative), â€Å"uptake† (adoption; i. e. , the proportion of settings and service agencies who are willing to initiate a program), and â€Å"implementation† (i. e. the intervention agents' fidelity to the various elements of a Tai Chi training protocol, including consistency of delivery as intended and the time and cost of the intervention). The intended results of this translation and dissemination project will provide an effective, evidence-based falls prevention package that can be implemented in community settings to improve functional ability and reduce fall prevalence among communit y-dwelling older adults. Summary The extant research evidence provides strong support for what was originally considered â€Å"anecdotal evidence† about the health benefits of Tai Chi for older adults. Overall, Tai Chi has been shown to have physiologic and psychosocial benefits and appears to be safe and effective in promoting balance control and muscular strength, and cardiovascular fitness for older adults. More research is needed, with rigorous scientific methodologies, to fully understand the mechanisms whereby Tai Chi produces these health benefits. From a public health perspective, immediate efforts are needed to translate programs that can be disseminated in local settings that target community healthy older adults. Fuzhong Li, Ph.

Core and periphery of Brazil

With reference to your selected region; locate and account for the emergence of a core, of relative wealth and a periphery of relative poverty. Discuss the relationship between the core and periphery, and note why the core is over-heating. What strategies have been initiated to tackle these regional inequalities? Brazil is the largest of the Latin American countries, located in the South American continent. Brazil's unequal development has given rise to two areas of spatial inequality. These are called the Core and the Periphery. The core is a relatively wealthy area, and is seen as the industrial hub of economics and industry. The Periphery however is less economically developed, and is characterised by a declining or stagnant economy. This prominent division has been caused by many reasons. The Core's success has resulted in it overheating, and outward migration has resulted in the periphery's problems getting worse. Government Strategies were then designed to improve the spread of development across Brazil. John Friedmann's model, shown above, shows us how Brazil has developed and its inequalities. The Core is in the South East of Brazil and is an area of industry, with high levels of technology, capital and investment. Unlike the North the South is fortunate to have a warm, temperate climate with a distinct cooler season along the coast. Development is easier in these Southern conditions, compared to the difficult climates of areas such as Sertio, in the North, where there are frequent droughts. Also the Core's location is beneficial too, being near the coast; large ports are possible and ports such as Santos in Sio Paulo are very important for importing and exporting for Brazil. These ports are built close to mineral resources and industry, for products to be exported. The core is home to huge reserves of iron and sizeable reserves of gold and gemstones, including emerald, topaz and aquamarine. These are mainly found in Minas Gerais, and rich minerals such as these are very beneficial to an area and they bring great revenue. Sio Paulo, Belo Horizonte and Rio de Janeiro are three cities that make up Brazil's industrial triangle, which is the centre of its industry. Sio Paulo is home to approximately one-third of the Brazilian GDP, with its economy based on machinery and automobile industry. Rio de Janeiro had the second largest economy after Sio Paulo and is home to the country's largest bank – Banco de Brazil. Belo Horizonte has become an international reference in information technology and Biotechnology. The Core has a good infrastructure, with efficient roads and railways that attract development. There is a large market for consumer goods and services, with a thriving work force, created by the large population. The South East of Brazil was the centre of trade in the country's colonial history too. Brazil was a Portuguese colony for over 300 years and the Portuguese exploited the land and exported minerals to Europe. The Southeast of the country was their centre of trade, so ports began to grow to export raw materials e. g. Santos and Rio de Janeiro. This was the start of the core's advanced development that left the peripheral areas behind in development. Foreign investment has accelerated the Core's development, with Germany as an example. Germany has invested $10 billion in Brazil, as 15% of its total foreign investment. There are now 1,024 German companies present in Brazil. Now German executives are being replaced by Brazilians to take over and run the companies. This will benefit the country even further, as its people become wealthier. As well as Germany, the united States have invested too, and Sio Paulo is considered to headquarter more American Companies than any other city outside of the U. S. The Car Industry has been a catalyst for development. With Ford, General Motors and VW in Brazil, hundreds of component suppliers have been attracted. Near to VW's plant for bus and trucks, is Volta Redonda, Brazil's main steel industry. This thrives from the car industry in Brazil and brings 1800 more jobs and $250 million of investment to Brazil. The Periphery is quiet different, located in the Centre West of Brazil. The Peripheral areas often suffer from declining industries, creating a negative image, which is unfavourable to new development in relation to the core. Low productivity and reduced demand for minerals has left the periphery less favourable in comparison with the core. Young and ambitious workers often leave the periphery to move the core, where there are greater job opportunities. This adds to the problems that the periphery faces, with a reduced work force and an aging population. The North has never been prosperous and has always been thinly populated. The development of Brazil's peripheral region has been stunted by its many problems. Environmentally, the peripheral areas in the North- East suffer epic droughts. This area is struck by mild droughts every 3years and a severe one every 12. Any remaining water is unsafe to drink and cholera strikes in epidemics. The temperatures through the dry season can reach 42iC and the temperatures and dry conditions make development very difficult and slow. The land available for growing crops is scarce and the soil is generally poor, thus meaning farmers that are dependant on one crop can't grow it, are struggle for food for their livestock. The people often have no or little education and can only get jobs in unskilled sectors and industry is mainly in agriculture. Most people are dependant on cottage industries and specific crops. The Northeast is the poorest region of Brazil, with the worst HDI rates of the country, mainly in the rural areas, which suffer from long periods without rain. This is somewhat ironic since the Northeast, during Brazil's colonial era when sugar production was higher, was the most prosperous region in all of South America. Health care is very bad, malnutrition is common in people living in these areas and child labor is a concern, as is child prostitution in major cities. Prostitution in the major cities has become an enormous problem, caused largely by the low Brazilian minimum wage as well as sexual tourism. In contrast to the situation occurring in the other Brazilian regions where social problems are worse in bigger cities, social problems in the Northeast regions are worse in the rural and small communities of the interior, lessening in bigger cities near the coast. With a lack of mineral resources and a poor infrastructure the Northeast of Brazil's development was very slow, especially with little energy resource to aid it. The quality of life in the Peripheral areas was low and the higher wages in the core appear much more favourable. The Core has its Problems too, overcrowding of people and competition for business, resulted in the core overheating. People move to the Southeast to improve their quality of life. However so many people now live and work in the big cities of the core that this begins to create its own problems. Since not enough housing can be provided for all these people or indeed afforded, people make their homes on unreclaimed public land. This resulted in a high occurrence of Shanty Towns or Favelas. These areas of irregular and poor quality housing are often crowded onto hillsides. Landslides in such areas, caused primarily by heavy rainfall but worsened by deforestation, are frequent. In recent decades, favelas have been troubled by drug-related crime and gang warfare. There are rumors that common social codes in favelas forbid residents from engaging in criminal activity while inside their own favela. Favelas are often considered a disgrace and an eyesore for local people within Brazil. The overcrowding caused by in-migration in the cities results in congestion and air pollution. This is worsened by the industrial pollution from manufacturing companies and from petrochemicals. Competition from other companies has resulted in closures of existing ones, meaning jobs are lost. Also wage rate were seen to be lower elsewhere so some businesses have chosen to move, to pay lower rates. The port of Santos had noticeably higher holding charges than other major ports; commerce was lost here as companies left. Under Unemployment is an issue in Brazil, this is where people hold jobs that don't contribute to the country's productivity. These are jobs in the informal sector such as, camelos, street vendors and prostitution. The minimum Monthly wage is R$200, although about 30million people in Brazil are not even making that much. The Brazilian government designed strategies to spread development across Brazil, with the Amazon region and the Northeast as the main problem areas. To begin the alterations a nationwide transport network was built, this included the Amazonian Highway. This re-encouraged mining and other economic activities to develop in the Amazon region. Two main approaches were used to tackle regional differences. These were the top-down and the bottom-up approaches. The top down approach is central around the government's decisions and doesn't really involve the people. Governments often concentrate their development resources in Growth poles, such as Brasilia and Recife, with the hope that economic growth will take place and spread to surrounding areas. Also growth corridors are often designated, that are designed to encourage industrial investment. These are often positioned along major roads that connect major urban areas and provide good access. In the Northeast there has now been heavy investment from new industries using power from the Sao Francisco River and the capital city was moved from Rio de Janeiro to a new city Brasilia. These are Top-down approaches, where government decisions try to overcome the disparity between the rich and the poor. Bottom-up approaches are centered on the people, helping them to help themselves. Local communities are consulted about the best ways to improve their quality of life, and they together plan the best methods. The government offered incentives to encourage businesses like Grendene to move away from the core. In this case the shoe company Grendene, worth $100billion, moved to the North East. The Capital of Brazil used to be Rio de Janeiro but in 1960 the Brazilian government decided to build a new capital inland, Brasilia, in an effort to develop the interior of Brazil. Brasilia acted like a magnet and changed migration patterns, and encouraged economic development in different areas. Many specific strategies were also implemented. Two regional development agencies were set up in 1959 called SUDENE and SUDAM, and they were responsible for managing the economic and social development of the country. SUDENE in the Northeast and SUDAM in the North; organized programmes such as; road building, the installation of power stations, building schools and developing ports. The work of SUDENE linked with the Northeastern pact of 1996 many improvements were made. The infrastructure in terms of irrigation, energy supply, transport and communications were improved. Canals were formed to link up rivers, dams were built and the drinking water was improved. Also efforts were made to modernise agriculture, to promote subsistence farming and cottage industry, to avoid the worst effects of droughts. Beer brewing plants were moved from Rio de Janeiro to Ceari, the Antarctica and Kaiser breweries created new jobs and revenue. This followed other industries moving to the northeast to lower labour costs and tax breaks. Also the state Maranhao has begun to attract companies from Taiwan, with and expected benefit of $1 billion. This move is to find cheaper labour and the abundance of raw materials in the area. Brazil now has a good tourism industry set up, with visitors coming to the beautiful locations along the north east coasts especially. Although progress has certainly been made, the regional programmes have not lived up to their entire expectations. Sustainable growth wasn't always considered and tax incentives made quick short term solutions. Further development in the Northern areas of Brazil has meant huge areas of forest land have been cleared under the grounds of land improvement, but deforestation is posing a larger threat. Global climate change has resulted in stricter rules, which could hinder their progress. The increasing debt of the country has meant that there is less and less capital available for investment. The gap between the core and the peripheral regions in Brazil has certain closed a little but there is certainly more to be done.

A Way To Tackle Poverty In Indonesia Economics Essay

A Way To Tackle Poverty In Indonesia Economics Essay Some indicators can be used to measure the development of a country. One of them is the rate of the poverty. Not only how this measurement be used in a developed country but also in a developing country. In other hand, many policies to reduce poverty have been made by the government or the multinational organization such as World Bank or United Nation. The big question is why it is that important to overcome poverty. Then the next question would be whether the policies have significant impact to decrease the rate of poverty. If the answer is ‘not’, are there any other solutions to help people who are still in the poverty lines? Therefore, this paper will provide descriptive issues about the recent condition of poverty and how social entrepreneurship can becomes the solution to tackle the poverty in developing countries specifically Indonesia. Keyword: Social Entrepreneurship, Poverty SOCIAL ENTREPRENEURSHIP PARADIGM: A WAY TO TACKLE POVERTY IN INDONESIA By: Huda Jamilah Poverty at Glance United Nation (1998) defines poverty as violation of human dignity. Usually, the poor does not have sufficient basic capacity to participate effectively in society. In addition, poverty is pronounced deprivation in well-being (World Bank, 2000). Poverty is the deprivation of food, shelter, money and clothing that occurs when people cannot satisfy their basic needs. We can say someone who earns under $2 a day is face absolute or extreme poverty. The proportion of the developing world’s population living in extreme economic poverty fell from 28 percent in 1990 to 21 percent in 2001. Most of this improvement has occurred in East and South Asia. In East Asia the World Bank reported that â€Å"The poverty headcount rate at the $2-a-day level is estimated to have fallen to about 27 percent [in 2007], down from 29.5 percent in 2006 and 69 percent in 1990.† In Sub-Saharan Africa extreme poverty went up from 41 percent in 1981 to 46 percent in 2001, which com bined with growing population increased the number of people living in extreme poverty from 231 million to 318 million   [ 1 ]   . Poverty can be understood simply as a lack of money, or more broadly in terms of barriers to everyday life. But the truth is poverty rate cannot be decreased until zero condition so that policymakers always have poverty on their development agenda for some reasons. Many studies show some aspects that have caused poverty. Specially, economic factor is the main cause of poverty. Chen and Ravallion (2001) revealed that from 150-country level data, the change in mean income can affect poverty rate. It indicates that at least 80% of people earn less than $10 a day   [ 2 ]   . The total wealth of the top 8.3 million people around the world, rose 8.2 percent to $30.8 trillion in 2004, giving them control of nearly a quarter of the world’s financial assets. In other words, about 0.13% of the world’s population controlled 25% of the worldâ⠂¬â„¢s financial assets in 2004 (World Bank, 2008). In Indonesia, although the rate of poverty decrease to 12,49% this year, the sum of pauper still 20 until million people. Besides, they should face the high rate of inflation year to year. There are several majors causes poverty in Indonesia. Low rate of minimum wage, unemployment, difficult to access information, and lack of entrepreneur.

Global warming is it real or not Research Paper

Global warming is it real or not - Research Paper Example Due to the rise in temperature, much of the living organisms are affected most of which die. Researchers suggest that the rise in the concentration of these greenhouse gases results in the Earth getting warmer gradually. This concentration occurs, for example, by the release of gases like CO2 in the atmosphere through natural processes and also by industries and factories that burn fossil fuels. Deforestation is another cause of increase in CO2 concentration in the atmosphere since trees are the most important absorbers of CO2 and when they are cut down, CO2 increases and thus concentrates the atmosphere. The debate whether global warming is real or not is going on and it is being researched whether increase in the level of greenhouse gases like CO2 will eventually lead to man’s death by warming up the Earth to an unacceptable level. In my view, global warming is as important an environment issue as air pollution or ozone depletion is, and needs serious consideration so as to save the Earth and the life. Reason 1 Now, I discuss the reasons behind my thesis statement. I believe that global warming is real because the stakeholders are many. Humans are being affected by this problem and will continue to get affected if it is not solved. Human beings are the most important stakeholders of global warming and are also the cause of it. They will have to understand that their communities are at stake due to abrupt rise in sea level, massive storms and hurricanes, and heat and cold waves. For example, the year 2007 brought worst floods in the history of many countries like Malaysia, UK, North Korea, and other African countries. Pakistan saw the worst flood in 2010 that took millions of lives and took the shelter of thousands of people. After human beings, the next important stakeholders are the animals and plants. Some animals are able to move to places of acceptable temperature but some are not able to cross the mountain barriers and waters. Plants cannot move, so they die. Another stakeholder is the global governments whose vision toward solving the issue of global warming depends upon the views of their citizens. Many of these governments have not taken satisfactory moves toward the solution of global warming but there are other examples like Kyoto Protocol of 1997 which planned to counter the climate change issue. The Southern Baptist Convention of June 2007, which was considered as the country’s largest Protestant denomination (Miller, 2008, p.128), raised concerns about the fact that global warming will continue to affect the poor of the country because even if steps are taken to counter global warming by reducing the number of factories that emit CO2, this will result in an increase in the cost of energy that will ultimately affect the poor. Businesses are the only stakeholders that will not make movements against the global arming issue so much so that they will even try to stop the decrease in global warming. This is because businesses tend to run such factories and industries that emit CO2 into the atmosphere and no business would want to end his business. But not all businesses work in this manner. For example, FedEx is such a company that tends to decrease global warming by shifting its entire fleet of delivery trucks to hybrids. Reason 2 I believe that global warming is real also because it is resulting in many climate changes. Everybody will

The Important Key Principles for Developing Reading Skills Essay - 1

The Important Key Principles for Developing Reading Skills - Essay Example A number of methods and techniques that demonstrate the implementation of these theoretical perspectives in the classroom are also articulated, including methods for specific class environments. Contemporary research into foreign language reading instruction notes that teaching models are greatly varied. Teaching models in first language reading have served foundationally as models in teaching second-language reading. Stahl and Hayes (1997) have discussed the ways that academic models influence and help shape approaches that teacher’s adept in the classroom. The types of models also change with practitioners’ age and experience.The main concern is that the difference between first language reading teaching and second language reading teaching is that the students have already developed first language reading skills that are influencing the second-language reading process. The different orthographies of the first-language also affect the second-language reading ability a nd researchers argue that this must be taken into consideration when developing lesson plans. Second language reading theory dates back to the inception of psychology as a formal discipline with cognitive theorists such as William Wundt. This research focused mainly on investigating perceptual issues. Beginning in the 1880s researchers fore-grounded the foundations of what came to represent the predominant focus of studies for the next century. In 1908 Huey published Psychology and Pedagogy of Reading which shifted focus in a more behaviorist slant until the 1960s. With Syntactic Structures and further attacks on behaviorist processes, academic attention shifted back to perceptual issues, with researchers investigating reading speed and eye focus. Notably, it was around this time that reading comprehension became a major issue for teachers. Today there are a number of key principles that are crucial to teaching reading in the foreign language classroom.  

Part 2 Essay Example | Topics and Well Written Essays - 1250 words

Part 2 - Essay Example the Floor Mosaic Fragment Depicting Bacchus was merely created through stitch or other form of material, but I discovered that this extraordinary piece of art was created before the 5th century ( 325-330 CE) using tiny pieces of limestone tesserae. The Floor Mosaic Fragment Depicting Bacchus is a piece of art that has left many astonished for many years. It clearly portrays the amount of work the artist put in to come up with this remarkable sculpture. It is made up of carefully placed limestone tesserae with well-defined dimensions of 117.5 x 117.5 Cm. According to the RISD Museum, this particular piece of art was created before the 5th Century in Antioch modern day Antakya, Turkey. The entire form of this figurine is a perfect square. This square bounds a circle with a series of waves, which further portray the image of Bacchus. Orange is the dominant color, and it creates the image of a pure nature of Bacchus due to its drenched form. One is emotionally drawn to the art as it has this tender and soft appearance. It is also evident that Bacchus is among the elite in the roman society due to the fact that he is wearing classic roman attire with laurels on his head. The artistic style itself has common features with that of a more recent artist, Rembrandt, who manifest thick marks of brushes as seen in the Floor Mosaic Fragment Depicting Bacchus. Both of these artistic works may look rough when closely analyzed, but it is not until one examines them from a distance that they really appreciate the way the colors blend to distinctively bring out the true nature of both works of art. Some of the most outstanding individual features can also be seen from a distance. These are the signatures of the artists that really endorse the art. For instance, a close examination of Bacchus cannot reveal the roman leaves in his head as they are seen as mere pebbles or just limestones. However, the elaborate detail of this particular artwork can be generally appreciated from

The History of Oil and Gas in China Essay Example | Topics and Well Written Essays - 1250 words

The History of Oil and Gas in China - Essay Example China was the first country to discover the presence of oil accumulations in salt wells. The Chinese identified beforehand the significance and the possible use of oil and gas in boundless applications. Early on in history, about 500 B.C., consistent with some historical accounts about China, the old Chinese express about wells with the depth of 100 feet holding a significant volume of water and natural gas. Also, the Chinese were pioneers in conceptualizing the use of bamboos to serve as pipelines to draw natural gas and oil from wells. These recovered gas and oil were originally used for lighting (Business Reference Services, "History of Oil and Gas Industry"). In addition, the Chinese eventually ventured in searching and excavating wells with depths of over 2000 feet (American Petroleum Institute, "All about Petroleum - As Old as History").While China was the first country to venture in the exploration and excavation of oil and natural gas reserves, it was not the first country to take innovative approaches in developing petroleum products like kerosene, gasoline, etc. It commenced adopting a modernistic method in developing oil and gas products only during the 1950s. Even up to the present, China is comparatively fresher in modern oil and gas discovery and production compared to the US. Initially, China was an oil importer but later managed to become independent; and even became an exporter between 1965 and 1993; however, it went back to being an importer in 1993.

Compare the role of women in Caroyl Churchill's top girls and Essay

Compare the role of women in Caroyl Churchill's top girls and Shakespeares taming of the shrew - Essay Example It revolves around the theme of mistaken identity of two sisters Katharine and Bianca. Katharine is apparently rude, ill tampered and defiant while Bianca is meek and nice with moderate manners. Both girls fight for gaining their father’s attention. Katherine’s jealousy and selfishness is due to Bianca’s approval by everyone as she says, â€Å"She is your treasure, she must have a husband; I must dance bare-foot on her wedding day† (The Taming of the Shrew. 2.1.35-36).1 Katherine is independent and has free will, but at the same time she is bitchy and her father want her to get married at any cost. On the other hand, Bianca pretends to be obedient and portrays the image of innocent girl who submit to her elder’s will. Shakespeare’s woman is wild, rebellious, ruler or suppressed by the male dominated society. He reassigned the role to women who independently operate in a social structure which is not favorable for her. However, right role for woman in Shakespeare’s point of view is submission to man’s will; be it her father or husband. Initially Bianca is showed as right and good because of her humble behavior towards orders, irrespective of what is going on inside her. Katherine on the other hand is rejected due to her insolent doings besides her independent and free spirit. At the end of play, role of both sisters shift just because of submission to their husband’s will, irrespective of what is going on inside their heads. The word taming reminds me of animals who need to be trained in order to be ready to serve better. Katherine is resembled with many animals and objects, for example, title itself suggests her to be a shrew, a mouse like animal. She is also compared with asses, horses and hawks. This idea can be observed in Act III, Scene II clearly when Petruchio says: Male domination over woman is obvious in the

Monopolies - Gas and Electric Essay Example | Topics and Well Written Essays - 250 words

Monopolies - Gas and Electric - Essay Example Government’s intervention leading to monopolization of the gas and electric sectors of the given country will have positive and negative implication to the general economy. Government’s intervention in such businesses will ensure that consumers receive better services from the traders of the particular product (Tucker, 2011). Government will also help consumers exercise maximum sovereignty without any form of manipulation by the individual traders. In addition, government’s intervention in monopoly of gas and electricity will help in ensuring that consumers get quality products and that traders comply with the safety standards. According to Rittenberg, et al (2008), the negative experience that will occur when government intervenes, forming monopolies in gas and electricity sectors will include high cost of production as the producer will be unable to pass the costs to consumers. When costs of production rises, producers will strive to limit the use of raw materials and this may compromise innovation. Furthermore, government’s intervention in monopoly of gas and electricity may lead to skyrocketing of prices of the products due to the raised standards of services, which will have adverse effects to the lower economic class (Rittenberg, 2008). Moreover, government’s intervention in monopoly trade of gas and electricity will also derail research process and spirit that a company may have to develop other ways of producing the particular

Democracy and Development - Research Paper Example   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Globalization has become the dominant factor in the development of civilization of the world in the XXI century. Globalization is the process of market-driven, rather than government forces. Globalization is a fusion of national economies into a single, global system based on ease of movement of capital, on transparency, on the technological revolution. The contours of global consolidation are business in the distant future. In this context, the role of national states to regulate economic and social processes will continue for many years.( Acemoglu,Robinson 2006) A testament of the nation-state activity is the activity of the "Group of Eight" - the U.S., UK, France, Germany, Italy, Canada, Japan, Russia. At its annual meeting of leaders of the "Group of Eight" the global economy is discussed, poverty and wealth, and environmental problems. In the past three years, the leaders of the "Group of Eight" discussed the issues of nuclear security and disarmament, i nternational terrorism. Polar position in relation to a group of rich countries have the least developed countries (LDCs). Since the beginning of the 70s that number had increased to 40 in 1986. The countries LDCs are characterized by extremely low standard of living. Geographically, the majority of poor countries are a countries in Asia and Africa. But a number of states in Asia managed to make significant progress. In 80-90s were often mentioned the so-called Asian dragons (Taiwan, South Korea, Hong Kong, Brunei, Singapore, Malaysia). A whole group of Asian and African countries can not escape from the clutches of poverty. Among these countries there are Afghanistan, Bangladesh, Bhutan, Gambia, Djibouti, Mali, Tanzania, Togo, Chad, Ethiopia, etc. The question of Romania and Poland After the Revolution of National Salvation Front, led by Ion Iliescu, took partial multi-party democratic arrangements and the free market. There were revived several major political parties, of the pre- war era, such as the Christian-Democratic National Peasants, the National Liberal Party and the Romanian Social Democrat Party. After several major political rallies, in April 1990, a protest sit-in, challenging the results of the recent parliamentary elections began in University Square, Bucharest accusing the Front to be composed of former Communists and members of the Securitate. The protesters did not recognize the election results, considering them as undemocratic and requested exclusion from the political life of former high-ranking participants of the Communist Party. The protest quickly grew to become an ongoing demonstration (known as Golaniad). Peaceful demonstrations deteriorated into violence, and strong intervention of miners from Jiu Valley has led to what is remembered as the June 1990 Mineriad. (Iliescu, Tismaneanu 2006) Subsequent decay of the Front has made several political parties including the Romanian Democrat Social Party (later the Social Democratic Party), D emocratic Party, and (the Union for Romania). First Romania run from 1990 until 1996 through several coalitions and governments with Ion Iliescu, and as head of state. Since then there have been three democratic changes of government: in 1996, the democratic-liberal opposition and its leader Emil Konstentinesku took power, in 2000 the Social Democra

Kerala Essay Example for Free

Kerala Essay Kerala, the ‘God’s Own Country’, lies in the extreme Southern part of India. It has an area of 38863 sq. km and a population of 3. 18 crores. Kochi, or more familiarly, Cochin is a city of many parts. Around for a long, long time, Kochi played a pivotal role in the development of shipping and trade in the region. Kochis prime location on the west coast, its fine bay and protected harbor made it popular with seafarers and merchant ships who made frequent stops to stock up on spices, coffee and wood enroute to the rich markets of Europe and West Asia. And so down the ages, Kochi prospered as a busy port city and commercial centre. Its seafront is still extremely relevant to Cochin and to India: it houses a Naval Base and one of India’s busiest ports. It’s twin city, Ernakulam, is an important railhead and industrial centre. Kerala – God’s own Country tagline has been used because of its location, landscaping and its surroundings. It is the amalgamation of lush and tropical Malabar Coast on the west along with verdant backwaters in the centre ranging from Cochin to Kollam and Nilgiri mountain range covered with tea plantations in the east. Kerala The God’s own country Kerala, meaning â€Å"land of coconut trees†, is one of the relatively well kept secrets of all the exotic destinations in the world. However, Kerala’s popularity has increased over recent years. National Geographic† travel magazine lists Kerala among the fifty must see locations in the world. Not surpirisingly, the State Tourism Department promotes Kerala’s natural beauty, breathtaking lush landscape and tropical beaches as â€Å"God’s own country†. The result has been a signifiant influx of tourists and foreign visitors. The Sanskrit saying â€Å"athithi devo bhava†( treat your guest like God, with respect and honour) is ingrained in the collective ethos of the people of Kerala.

The Modernization of Japan Essay Example for Free

The Modernization of Japan Essay According to Contemporary Japan: A Teaching Workbook in Columbia University and East Asian Curriculum Project: â€Å"the arrival of United States naval fleet commanded by Commodore Matthew C. Perry has ended the seclusion of Japan from the outside world, particularly western. Perry then instructed to open Japan to foreign trade and diplomatic contact†. The Edo bakufu, recognizing United States military superiority, signed a treaty of friendship during a second visit by Perry in 1854. In 1868, the Meji restoration was successful and totally isolated from westerners influence. A new government was installed composed and led by rank and file samurai from the domains of Satsuma and Choshu. The newly restored government pledged to restore a new nation that shall be modernized and independent. As further cited by the Contemporary Japan: A Teaching Workbook in Columbia University, East Asian Curriculum Project: â€Å"it meant finding a new symbol around which Japanese people could rally (the Meiji Emperor), a new sense of investment in the modern society being built, the opportunity to make a â€Å"success† of oneself, and the dismantling of the old feudal order†. Subsequently over the period, in favor of a modern centralized government, the old feudal domains were abolished. The old feudal class distinctions were notably the samurai class. Resistance and contradiction in the newly restored government, as Saigo Takamori led a rebellion in 1878, were repelled. The Meji government proved its imperial power to rebuild its cultural heritage, society and the way of life. The government, as led by the Meji Oligarchs, has paved its governmental system into parliament. A constitution was enacted and the exercises of election that has finally outlined the parliament proceedings like modern states.

Indirect Realism: A Plausible Theory Of Perception?

Indirect Realism: A Plausible Theory Of Perception? In this essay I am going to be examining some of the main claims made by indirect realism as well as looking at some of the fundamental problems these claims cause for the theory, such as the epistemological problem, the ontological problem, and the fact that the theory inevitably leads to solipsism. Indirect realism first arose in an attempt to resolve some of the problems faced by common sense realism, where it became apparent that the assumption that our senses almost always give us true information about the nature of the external world is implausible. Indirect realism therefore modifies the ideas presented by common sense realism, by suggesting that what we perceive directly and are immediately aware of is not the world or the objects within it, but sense data. Indirect realists are far from denying the existence of the physical world, but simply claim that the physical objects in the world cause our sense data, and that the sense data we experience represents the external world, to an extent. For example, when I see a horse, I do not perceive it directly, as common sense realism would suggest. I have no sensory contact with the horse, and what I am aware of is only a mental representation, sort of like an inner picture, of the horse. My visual experience is not directly of the horse; however indirect realism claims that it is caused by the horse. What I am aware of is the representation of the horse, which my senses produce. As Dancy explains, Indirect Realism argues that in perception people are indirectly aware of the physical worldà ¢Ã¢â€š ¬Ã‚ ¦in virtue of a direct awareness of internal, non physical objects.  [1]  This means that although someones idea of an object may resemble the object itself, a person can only ever be aware of their idea and never the object itself. Indirect realism also seems to provide a response to the objections to common sense realism, raised but the Illusion Argument. In the instance of colour, for example, one jacket can look completely different colours when viewed in different lights. If we were to then examine the fibres of the jacket material in more detail, we would probably find them to be a variety of different colours. The way it is perceived also depends on the viewer, for example, someone who is colour-blind may see the jacket differently to someone with full colour vision. In view of this, it doesnt seem to make sense to say that the jacket is really yellow, or that its yellowness is independent of the perceiver. In an attempt to explain this kind of phenomenon, indirect realism introduces the notion of primary and secondary qualities. Primary properties resemble the real properties of the object. John Locke, describes them as being utterly inseparable from the body  [2]  and necessary for conception of it. Primary qualities exist both in the world and in sense experiences, and can be experienced by more than one sense. They are measured by physics and are qualities which the object actually has, regardless of the conditions in which it is being perceived or whether it is being perceived at all. Primary qualities include shape, size, position solidity, extension, motion and rest, and number. Locke argues that secondary qualities are nothing in the objects themselves but powers to produce various sensations in us,  [3]  and conceptually inessential. These qualities exist only in sense experiences and can only be experienced by one sense, but objects in the physical world have the power to produce these experiences in us. It may seem as though these properties are really in the objects we perceive, for example, that the yellowness is somehow part of the yellow jacket, however the yellowness that we experience is simply the objects power to produce yellow images in a normal viewer, under normal conditions. The ideas we have of secondary qualities dont resemble the actual objects but are simply a product of the kind of sensory system that we have. Secondary properties include colour, temperature, smell, taste and sound. One major objection to indirect realism is that it seems to make the real world unknowable. It only makes sense for us to say that A resembles B, if it is possible for us to be directly aware of both A and B, in order for us to compare the two. This creates a rather fundamental epistemological problem for indirect realism because the theory states that our sense experiences of the primary qualities of objects resemble the actual qualities of objects in the external world, however, it also states that we can never be directly aware of the external world, so we therefore have no way of checking whether our sense experiences do in fact resemble the external world at all. For example, if my sense experience of a ball is round, I have no way to check that this corresponds with the actual shape of the ball in the external world. We are entirely limited to the evidence of our senses, and since these work by means of mental representations, it seems as though we can never gain any direct inf ormation about the actual properties of the ball, or any other object in the external world. Indirect realism has also led to a problem related to what is known as the veil of perception, which refers to things that are seen indirectly, and not as they are in themselves. This is because there is a veil that we cannot penetrate, because the things that are being perceived (in this case, objects in the external world) exist independent of sensation. This creates a rather fundamental ontological problem for indirect realism, because it only seems to make sense to say that A is caused by B if it is possible for us to know what B is, however the veil of perception seems to prevent us from doing this. Since we are unable to directly access any physical objects in the external world, it is possible that our sense experience could be caused by something entirely different, for example, Descartes evil demon, God, a mad scientist, the matrix, or ourselves. We have no way of getting outside of our own perception to find out what is causing our sense experiences, if there is in fact anything causing them at all. This is another serious problem for indirect realism; it can lead to solipsism, which is the belief that nothing exists beyond oneself and ones immediate experiences. It suggests that since we cannot know the external world and other minds directly, they may well not exist at all. Solipsism is argued to be philosophically absurd for two reasons; the first being the phenomenological reason, which claims that if we were the only beings that existed, we would not feel emotions such as shame, embarrassment and guilt, which require the existence of another person or being in order to have any effect. The second reason is that logically, solipsism just doesnt seem to make sense, and therefore any theory that leads to or allows for this view point, the way indirect realism does, is also argued to be absurd. In conclusion, it seems that although indirect realism does manage to overcome many of the problems faced by common sense realism, it also seems to create many more serious problems of its own. Although the theory at first seems quite plausible, the fact that it allows for solipsism makes it pretty much irredeemable. Indirect realism also fails to account for the causal relation between the external world and our sense experiences, and as we have seen through the veil of perception objection, we have no real reason to believe that our sense experience bare any resemblance to the external world at all. I think indirect realism would be much more plausible if it could offer some form of explanation of the interaction between our sense experiences and the external world. Mn0.5Zn0.5Fe2O4 Nano-material: Hydrothermal Synthesis Mn0.5Zn0.5Fe2O4 Nano-material: Hydrothermal Synthesis Title: Hydrothermal synthesis and photocatalytic application of Mn0.5Zn0.5Fe2O4 nano-material for degradation of Reactive Blue H5R dye In the proposed research work Mn0.5Zn0.5Fe2O4 nano material will be synthesized using hydrothermal technique for the degradation of reactive blue H5R dye. The chlorides of manganese, iron and zinc will be used for the synthesis of the Mn0.5Zn0.5Fe2O4 nano material. Then synthesized material will be used in water treatment for the degradation of reactive blue H5R dye through photocatalysis using visible light. The examination of the size of the particles and structural properties of the synthesized material will be carried out by using X-ray diffraction (XRD) technique and the morphology of material will be evaluated by scanning electron microscopy (SEM). Particle or grain size of prepared samples of Mn0.5Zn0.5Fe2O4 nano material will be computed using the Scherer’s formula. The photo-catalytic behavior of Mn0.5Zn0.5Fe2O4 nano material will be investigated by measuring the photo degradation rate of the dye. The stability of the nano-photo catalytic material will also be investi gated by the repeated use of Mn0.5Zn0.5Fe2O4. INTRODUCTION Synthetic dyes and different chemicals used in textile industries play significant role in environmental pollution. Some of these industrial chemicals and synthetic dyes decompose aerobically and anaerobically resulting in the formation of carcinogenic compounds (Neill et al., 1999). In the past few decades, there has been huge attention between scientists in increasing semiconductor photo-catalysts with great prospective for environmental protection applications like water disinfection (Ullah et al., 2012; Shahid et al., 2013). Most of the ferrite materials are known to show exciting photocatalytic capabilities for hydrogen or oxygen generation from water upon irradiation with visible light. Such visible light absorption properties, and their proper band edge positions with respect to redox levels essential for water splitting, are desirable for a water splitting photocatalyst to work under sunlight (Dom et al., 2014). Ferrite materials technology has now extended to a very progressive stage, in which the properties to a large extent are designed and controlled by engineers, to garb the particular function of the device. Because of their outstanding magneto-transport properties the mixed valence ferrites have involved huge scientific attention in the recent years (Ahmed and Bishay 2005). In the beginning works the ferrites were attained by soft chemistry and mechano-synthesis (Millotet al., 2007). Hydrothermal strategy is a promising synthetic method because of the low process temperature and very easy to manage the particle size. The hydrothermal procedure has several benefits over other growth methods such as the use of simple devices, catalyst-free growth, low cost, large area uniform production, environmental friendliness and less harmful (Aneesh et al., 2007). Moreover, no post-heat behavior is needed for the created nanoparticles, which makes this method extremely suitable as heat treatment might result in particle collection. (Haw et al., 2002) OBJECTIVE The objective of present research work is to produce Mn0.5Zn0.5Fe2O4 nano-sized particles by hydrothermal technique specifically for catalysis of reactive blue H5R dye. The structural properties of synthesized nano-photocatalyst will be studied by using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Photo-catalytic behavior of the Mn0.5Zn0.5Fe2O4 nanoparticles will be investigated by determining the photo degradation rate of the reactive blue H5R dye under visible light irradiation. Review of Literature Rath et al. (1999) synthesized Mn0.65Zn0.35Fe2O4 particles in nanosize (9–12nm) using metal chlorides via hydrothermal precipitation. The characterization was done with TEM, XRD, and VSM. The concentration of chloride ion and pH of precipitate played a vital role in retaining the preliminary stoichiometry of the solution of the nano-material. Whereas at low pH, incomplete precipitation of Mn was observed. Zn loss in the nano-particles at higher pH of precipitation was noted. Bujoreanu et al. (2000) investigated the structure of manganese ferrite in powder form which was prepared by co-precipitation method using MnO2 and FeSO4.7H2O. The powder material then was co-precipitated and aged at temperatures ranging from 55 to 59 oC, then washed and dried in the air at room temperature. By the addition 15% sodium hydroxide solution in the 2N cation solution the stoichiometric amounts of MnO2, FeSO4.7H2O and H2SO4 were precipitated Kosak et al. (2004) prepared nanocrystalline MnZn-ferrite with different morphology through single water-in-oil micro-emulsion comprising of n-hexanol, surfactant CTAB and an mixed metal sulfates solution. The mixture was precipitate with sodium hydroxide solution and oxidized with hydrogen peroxide. The prepared nano materials were characterized by using X-ray diffraction (XRD), BET surface analyzer, magnetometry and transmission electron microscope (TEM). Abdollahi et al. (2004) synthesized various compositions of manganese Mn doped ZnO. using precipitation method. XRD, TEM, SEM, EDX, BET techniques were used for characterization. The band gap measurement was done with UV-visible reflectance. XRD pattern showed no impurity peaks, indicating Mn-related secondary phases. The EDX showed the slightly lower amount of Mn doped on ZnO than the theoretical value and SEM showed that 1% Mn-doped ZnO well ordered morphology, homogeneous distribution of slightly lower particle size and low aggregation. Vaidyanathan et al. (2004) compared Mn0.9Zn0.1Fe2O4 synhesized through double sintering method and chemical co precipitation method in order to find the magnetic properties. The precipitated ferrites showed altered magnetic properties like magnetization (Ms), coercive field (Hc) and Curie temperature (Tc). The particles were reduced in size as compared to co-precipitated nano-sized particles. Arulmurugan et al. (2006) prepared by Mn1−xZnxFe2O4 used for ferro-fluid preparation.TG-DTA, XRD, TEM, VSM and Mossbauer spectroscopy was used for description. The ultimate approximated cation contents decided with the initial degree of substitution. The particle size and curie temperature (Tc) reduced with the rise in zinc substitution. The particles with greater zinc concentration, showed ferrimagnetic and super paramagnetic behavior at room temperature. Yimin et al. (2007) synthesized Mn1-xZnxFe2O4 using metal sulfate in aqueous ammonia. The TEM, XRPD, VSM and TGA were appled to demonstrate the material properties. The classification of the nanoparticles was evaluated and discussed. The effects of the reacting components and preparation methods on the Curie temperature, the magnetization and the size distribution of Mn Zn ferrite nanoparticles. Hejase et al. (2012) produced hyperthermia inducing agents manganese zinc iron magnetic nanoparticles. The structure was recongnized using scanning electron microscopy, X-ray diffraction, and a superconducting quantum interference device. The curie temperature, saturation magnetization, remnant magnetization, coercive field, and hysteresis were analyzed which showed that adapting the Mn contributed to the modification of properties of the magnetic complex. Shahid et al. (2013) synthesized high effective ZrFe2O5 nanoparticles using co-precipitation method. By (EDX) the chemical composition of nano-materials were analyzed. (FE-SEM) was used to study the morphology. The structural properties of the produced material were appraised by XRD technique. By evaluating the degradation rate of TBO dye in aqueous solution the photo-catalytic action of ZrFe2O5nano-particles was examined under visible light irradiation in the presence of ZrFe2O5nano-particles. By increasing time of exposure under visible light irradiation a steady decrease in absorption peak was noticed. As after 140 min of contact to visible light the 92% degradation effectiveness was detected. Besides, ZrFe2O5nano-photocatalyst could be recaptured and reprocessed purely. The rate of TOC elimination and TBO was decreased by only 10% and 5% respectively, afterward seven cycles of use, representing the more photo-stability of the synthesized nano-photo-catalyst material.

Cuban Situation :: Cuba Politics Economy Economics Essays

Cuban Situation Cuba needs cows. In January of 2004, a Cuban delegation visited Florida to inspect beef and dairy cows to repair Cuba’s languishing cattle industry. Moreover, under the auspices of the U.S. Trade Sanctions Reform and Export Enhancement Act in 2000, the United States exported $350 million dollars worth of American agriculture products to its island neighbor in 2000 (Bussey 1). This budding trade relationship is symptomatic of a broader move by Cuba to fully re-insert itself in the global economy. Deprived of the protective cocoon of Soviet trade agreements and faced with economic crisis and stagnation, Cuba’s leaders have responded with limited economic reforms. It is clear, however, that Cuba will not emulate the rapid liberalization of much of Eastern Europe and Latin America. A brief review of Cuba’s economic performance since the fall of the Soviet Union reveals a trend of liberalization bred of necessity. Nevertheless, the mixed performance of the Export-Pro cessing Zones and the government’s grudging acceptance of tourism reveal a tension between Cuba’s need for foreign currency and direct foreign investment and a desire to insulate and preserve Cuba’s existing domestic apparatus. This tension underlies Cuba’s ongoing economic transition and has prevented wholesale market liberalization. Cuba’s future movement towards market reforms will be carefully managed by the Castro government to protect Cuba’s revolutionary legacy and to maintain control of political opposition. The fall of the Soviet Union devastated the Cuban economy. Cuba’s GDP contracted by 35-50% from 1989-1993 (LeoGrande quest 5). As a percentage of total Cuban trade, the Soviet Union’s share fell from 66% in 1990 to 15% in 1994 (5). Moreover, Russia reneged on its oil agreement, and fitful exports caused energy shortages in Cuba. Production and consumption plummeted. From 1986-1991, Castro undertook a rectification campaign to stabilize the economy as the Soviet Union decreased its support and eventually collapsed. The plan â€Å"focused on re-centralizing economic planning authority, dismantling the [Soviet-sponsored socialist management system] and market mechanisms, abolishing the free farmers markets launched in 1980, and combating corruption† (4). In addition, Castro tried to address the massive trade imbalance by reducing imports and reinvigorating the export sector. This program was a resounding failure. More domestic and far-reaching reforms were necessary to save the economy from crisis. Economic disaster had erected a serious challenge to Cuba’s socialist program. In 1991, Castro’s announcement of a â€Å"Special Period in a Time of Peace† marked the beginning of Cuba’s new era of liberalization.

The Pact Analysis Essay -- Essays Papers

The Pact Analysis Friendship is the support for most great inspiration. Friendship creates peer pressure, both positive and negative, and it is nearly unavoidable in everyday life. The author’s of The Pact were raised in the streets of Newark, New Jersey. They were faced with many dangerous decisions. Despite many tremendous distractions, they were able to apply knowledge gained from friendship and experience to help them through their lives to propel them to where they are today. As a child, I felt that having friends was the most significant cause in who I am today. Throughout my life I have had many friends who have influenced me in numerous ways, but now most of them have become distant acquaintances. Although the majority of these people have very little communication with me now, only a few childhood friends continue to still be a part of my life now. The most frequent is my first and best friend, Matt. Somehow this name creates a pattern that continues to show up all over my life. It seems that all of the closest friends that I have had in my life have this name. The communication between Matt and I was amazing and our connection was extraordinary. Matt and I were ten years old and we spoke to each other in a language that only we knew. The language was created out of personal words or phrases that we created to describe situations. Our understanding of life was endorsed by rare bonds, and close family relationships. The two of us became undividable when we first met in kindergarten. Matt’s parents were older in age than my parents. I thought his father to be a strict family figure, because of his experience as a retired PA State Policemen, and his hat that he wore proudly all the time displaying in large words â€Å"Vietnam Veteran†. His mom was very opposite in comparison with his father. She was pleasant and she seemed to take on situations with ease. Matt was a full year older than me, he was the last child in a family of four. His siblings were twofold his age, and I feel this significantly impacted the two of us. Much like Sam, Rameck, and George, the authors of The Pact, I was able to see and understand at a young age much of what could become of me by observing and learning what much of what my family, Matt’s family, and many of the neighbors around me had to teach. George, one of the authors of The Pact, tells how h... ... my old school that had now been taken away from me in my new school. Students wore more fashionable clothes, and their attitude was different from what I was used to. They were more arrogant and I didn’t know why. This new atmosphere was challenging, and because I hadn’t grown up in the area, I became lost. I remained alone, only talking to Matt over the internet, but after a couple years we simply grew distant. I was without a stable friendship, and because of this I was almost easily manipulated. George, one of the authors of The Pact, explains this situation by stating â€Å"[i]n my experience, friends have more influence on one another’s lives than most anyone else does especially in those teenage years when kids are trying to discover who they really are† (107). I, like the author’s of The Pact, gave in to peer pressure and in time learned many lessons. In order to be successful in life, you need to have positive influences, whether it is friends, nature, or family. Everyone at some point in time will suffer from not having these influences. The reality is that no matter what the circumstances, with the right attitude and determination, you can succeed and be successful.

Biblical Illusions in Toni Morrisons Song of Solomon Essay -- Song So

Biblical Illusions in Toni Morrison's Song of Solomon Song of Solomon, by Toni Morrison, is about a man named Macon Dead. Throughout this novel, however, he is known by all except his father as Milkman because his mother breastfed him until he was in his teens. The novel centers on Milkman's attempt to find himself. His family is a wealthy black family living in a poor black neighborhood, where Milkman's father prohibits Milkman from interacting with most of them, including his aunt. However, he ends up visiting her, and while there, he learns a little about his family's mysterious past and decides to look deeper into it. Throughout his journey into his past, one may notice a large amount of biblical allusions. The first and most noticeable of these allusions is the title of the novel itself. _Song of Solomon_ is not only the title of this novel, but also a biblical book. This book in the Bible is also known as the Song of Songs and the Canticles. It is a collection of songs telling the story of a conversation between King Solomon and his beautiful Shulamite Bride, who happe...

Police Personality Essay

The issue regarding the phrase â€Å"police personality† has acquired great debate. Arguably this has been primarily over the problem of definition and development. What is a police personality? How does it form? Is it a pre-existing condition, thus predisposing certain individuals to police work, or whether it is just a product of occupational socialization (on the job experiences). Perhaps the issue is not as simply dichotomous as that; conceivably it is an amalgam of both predispositions and experiences that shapes this intangible personality. Does this personality make them any different from the general population which they vowed to â€Å"serve and protect†? How do these attitudes and affect not only himself and the department he belongs to but also the police-community relation in general? These are some questions relating to the issue of police personality that will be answered along the way. To start with, how do we define â€Å"police personality†? There are a few who made several models or theories about this idea. According to G.A. Kelly (1955), personality is our abstraction of the activity of a person and our ensuing simplification of this abstraction to all matters of his relationship to other persons, known and unknown, as well as to anything else that may seem particularly valuable. His theory is based on the vantage point of personality as a personal construct model. G. Alport (1937), another theorist describes this as a three-pronged task for a certain individual: (1) self-objectification, (2) extension of self, (3) unifying philosophies of life. According to him, it can be further understood as a mixture of major and minor â€Å"traits† by which a single life is known and that a personality â€Å"trait† is a biological, psychological and social mixture that disposes a person toward specific kinds of action under specific circumstances. (Monte, 1999). With respect to the development of the police personality, Allport can be said to be adhering to the predisposition model-that a certain type of person becomes a police officer as opposed to the notion that job experiences shape the personality construct. A third psychologist, H. Kohut (1977) describes that normal development was a process of interaction between the growing infant and his mirroring and idealizing self-objects. This assumption tends to support the view that police personality is a mixture of the predisposition model and the experience model. But regardless of the process by which this certain personality has developed from, what are these traits that make up a police personality?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The characteristics usually associated with police personalities in present times are machismo, bravery, authoritarianism, cynicism and aggression. Additional characteristics have been associated with police personalities as well: suspicious, solidaristic, conservative, alienated and thoroughly bigoted (Balch, Skolnick 1977). In movies like â€Å"Lethal Weapon† which stars Mel Gibson, we see an image of a cop that is not only brave and proficient—but a super cop, who can handle almost anything that goes in his way. The movie â€Å"Training Day† by acclaimed actor Denzel Washington also depicts a vicious, sadistic cop. Gone are the days when people picture cops as men in uniform, walking around the neighborhood helping children to get their pet cat down from a tree (a Boy Scout persona). Modern pop culture and the media have greatly helped the public’s perception of today’s policemen.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Little is known about how these men undergo series of screenings in order to be accepted though. Before being hired, aspiring policemen go through several personality tests that determine whether they are capable enough to handle the job. Only men who display particular personality profiles (e.g. bravery, honesty, punctuality) are accepted to the force. But these screening, even with the help of psychologists, does not give us a clear picture of what police personality is all about. In contrast, it tells us what the police persona is NOT. There certain traits that make entry-level policemen unfit for the job. Examples are tardiness, excessive absences, alcoholism, and lack of assertiveness among many others.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   From the successful ones however we can gather some commonalities in their traits that may help us define police personality. People who enter the force turn out to be psychologically healthy and competent young men who display common personality features. They are generally assertive and restless, with a high degree of physical energy. One trait that stands out from this however, is cynicism. Some professionals view cynicism as counterproductive and in due course, harmful not only to the individual but to the department as well. It said to that for the most part, it is a precursor to corruption, brutality, and misconduct for men in uniform. However, some also believe that, in recent years, findings show that cynicism is to be considered a police survival tool (Caplan, 2003).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The police personality based on Skolnick’s (1977) idea of the â€Å"working personality† is composed of three main elements: danger, authority, and efficiency. The dangerous nature of being a police officer not only draws officers closer together but also makes them alienated from the general population. The sense of authority by police officers, experienced by interacting with the public, further makes them feel isolated. So is the notion of efficiency in which the use deception as a means of getting the job done. Some experts believe though, that the idea of alienation is not intrinsic to police officers, it rather lies in the community’s perceptions of the policemen. It is important that the community and the force work hand in hand in trying to rid the locale of criminality. In countries that are just developing, criminal cases are usually very high. Thus, the police force must be able to transform their image as a widely feared and despised organization to a friendly and service-driven institution that works in close partnership with the community. This is especially hard when the image of a certain department for example is a corrupt and brutal one. People tend to generalize that idea, and view the force being corrupt and all as a whole.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Examining the psychological and sociological paradigms on police personality we get a clearer view of what makes the police men different from the rest of the population. The psychological paradigm posits that people with certain personalities are drawn to join the force (predisposition model). On the other hand, the sociological model suggests that these traits are developed along the way (based from the day to day experiences of police officers). Police personality, as a distinct entity, does exist. It exists as a result of the convergence of a specific baseline set of desirable personalities and work-related socialization. It is also a utility of, and is strongly characterized by, a police culture, shaped by the needs of officers to uphold personal safety and augment their professional potentials.
