I.Introduction
On June 25th, 2013, news reported that heavy metal pollution of vegetables in Pearl River Delta was worrying. Excessive heavy metals not only affect the plants’ normal growth, but also accessed into the food chain by getting through enrichment of plants’ bodies, and affected human health. Vegetables’ heavy metal pollution is already a common topic, the crowd grew pale,and were very concerned about the contaminated vegetables will bring huge healthy hidden trouble. At the same time, according to the World Health Organization, the numer of the global cancer patients increase more than 14 million each year, and China has become the most serious country affected by the cancer all over the world. Also, the national cancer registry released every minute six people were diagnosed with cancer. With the advent of high incidence of cancer, in recent years, the word "LiuGan" in Chinese also gradually hots up. Scientists have found out thioglycoside is the key factor that affects the ability of the cruciferous vegetables’cancer resistance.…...

Cultural Impact and Cultural Sensitivity on Breast Cancer Screening

...The disparities between African American women and other races in regard to the incidences of and mortality from breast cancer are alarming. Studies have shown that minority communities are less likely to take advantage of preventative and detection care like breast cancer screening. Other studies find that a number of factors, outside of race and ethnicity play a role in this. Ultimately, approaching the topic from a holistic understanding and acknowledgement of the ways in which a person’s full background influence their values, beliefs, and decisions and present barriers to action – cultural sensitivity, namely – is essential to reversing these disparities. In “African-American Women, Self-Breast Examination and the Health Belief Model: Implications for Practice,” author Josephine McCaskill, PhD., APN, FNP, BC examines the fact that African American women, despite having lower incidence rates of breast cancer have a higher mortality rate, and the fact that findings show that “the adherence to recommended breast cancer screening guidelines is frequently reported to be lower in the African American population” (McCaskill p. 33). McCaskill begins by discussing the epidemiology of breast cancer, noting that it is “the most common form of cancer, resulting in significant deaths among African American women.” She discusses its origins, cell growth, and disparities among populations. Particularly, among women who are ages fifty and older, the mortality rate for......

Green Growth

..."Green Growth": A Necessity Green growth is a new buzzword among the policymakers around the world. For many policymakers it's a new magical word that can play a very significant role in the development of a country. Green growth is viewed as a key to sustainable growth. It has been recognized that there is an urgent need of transition towards green growth to achieve sustainable development and prosperity. As per Asian Development Bank "... green growth is an imperative not a luxury, for developing Asia". It is still not clear whether 'green growth' is a new transitional shift or just another gimmick to cover up inconsistencies between economic and environmental objectives of governments. There is no universally accepted definition of green growth. But normally it is being treated as a synonym to sustainable development. "Green growth is fostering economic growth and development, while ensuring that natural assets continue to provide resources and environmental services on which our well-being relies"-OCED. So green growth basically emphasizes on the efficient use of natural resources that minimizes pollution and environmental impacts at the same time it also plays role of environmental management and natural capital in preventing physical disasters. Main focus of green growth is low carbon growth that promotes growth with the help of creation of new environment friendly products. Green growth is matter of both economic policy and sustainable development. Politicians......

The Impacts of Population Growth

...Running Head: THE IMPACTS OF POPULATION GROWTH 1 The Impacts of Population Growth INR2012 THE IMPACTS OF POPULATION GROWTH At the beginning of the first millennium A.D., the world’s population stood at 300 million people. The Industrial Revolution in the 18th century raised living standards and spurred growth; in the year 1800 the world’s population reached one billion. The 20th century was marked by health advances that improved life expectancy and increased the number of children that would reach adulthood and bear their own children; in 1927 the two billionth baby was born, in 1960 the third, in 1974 the fourth, in 1987 the fifth, and in 1999 the sixth. We now stand in the year 2012 with a world population of 7 billion. The exponential rate at which population is increasing is a global concern. Economist and demographer Thomas Malthus voices that population will naturally exceed its resources and then famine, war, and disease will put a check on its growth (Malthus, 1798). In the face of these concerns, various states are formulating and implementing policies to control their population growth in order to achieve socioeconomic sustainability and ensure a better quality of life for future generations. “Population is determined by the interplay of two factors. One is the birth rate, or the number or people being born, and the other is death rate, or the number who......

The Impacts of Economic Growth

...The Impacts of Economic Growth Economic growth is the increase in the amount of the goods and services produced by an economy over time. It is conventionally measured as the percent rate of increase in real gross domestic product, or real GDP. There are many positives and negatives with economic growth. Economic growth improves standard of living through sustained GDP growth, it improves tax revenues and provides the government with more money to spend on healthcare, education etc. Growth boosts business profits, a stronger economy increases consumer confidence therefore allowing people to purchase luxuries and once again improve their standard of living. Economic Growth will also increase employment, as growth increases as do business profits, therefore companies have more available finances to be able to pay wages and therefore levels of employment increase. Economic Growth can help protect the environment, as business profits increase, companies have more finance and can therefore invest in carbon investment, innovation and research and development to reduce the amount of harmful substances released during the production stages, therefore reducing their effect on the environment. On the other hand, economic growth poses as a threat of inflation risk. Increase in demand may be more than available supply and will therefore cause prices to rise, so consumer confidence decreases along with standard of living and business profits. Economic growth can have a......

Vegetables and Fruits

...VEGETABLES AND FRUITS INTRODUCTION: High intakes of fruits and vegetables are protective against many forms of cancers. Vegetarians are less likely to contract cancer of the colon than meat eaters. A vegetarian diet is typically high in fibre, low in saturated fat and includes plenty of fruit and vegetables. Dietary fibre may help to protect against all the ‘Western’ cancers such as cancers of the colon, rectum, prostate, uterus and breast. We all know that fruits, vegetables, grains, legumes and nuts are healthy. There are a number of studies that show that consuming more of these plant-based foods reduces the risk for a long list of chronic maladies (including coronary artery disease, obesity, diabetes, and many cancers). This is probable factor in increased longevity in the industrialized world. On average, we eat two fruits and vegetables and too much saturated fats of which meat and dairy are prime contributors. A predominantly vegetarian diet may have beneficial effects for kidney and nerve function in diabetics, as well as for weight loss. Eating more fruits and vegetables can slow, and perhaps reverse, age-related declines in brain function and in cognitive and motor performance at least in rats. However, low protein diets associated with vegetarians, reduce calcium absorption and have a negative impact on skeletal health. Vegetarians’ avoidance of meat, eggs and dairy products can lead to deficiencies in iron, calcium and Vitamin B12. Infants who are......

The Impact of Tax Revenue on Economic Growth

...purpose of this research therefore, is to examine the empirical impact of tax revenue on economic growth. 1.2 STATEMENT OF RESEARCH PROBLEM Nigeria is a monoculture economy, over depending on the oil sector. This has also been seen to be responsible for deficiency in investment capital in the country. Amadi 2002 (cited in Adofu, 2009) opined, “With oil as the main source of foreign exchange, a one-product mono-cultural economy must be continuously deficient in investment capital. Oil is subject to the vagaries of international capitalism. Therefore, revenue from it must be subject to serious fluctuations”. The above situation in the country has created savings and foreign exchange gap. This culminates to a wide gap between the actual domestic investment fund and the required infrastructural investment for accelerating economic growth. So, urgent aggressive tax drive and prudent spending on the part of the government will be regarded as an alternative to bridge the gap. This research will be geared towards the impact of taxes generated on the growth of the Nigeria economy. 1.3 OBJECTIVES OF THE STUDY The study will focus on the following objectives: * To examine the impact of direct tax on economic growth. * To examine the impact of indirect tax on economic growth. * To examine the impact of other forms of revenue on economic growth. * To examine the impact of lagged tax revenue on economic growth. 1.4 RESEARCH HYPOTHESES The hypotheses of this......

Cancer Cell Growth

...Cancer is a group of 200 or more diseases of controlled cell growth. The treatment of cancer can be very difficult process. Breast Cancer is most prevalent form of cancer among women and second leading cause of death. From a clinical standpoint radiation chemotherapy not only made strides in preventing the reoccurrence in cancer but also has some side effects that needed to be treated in order for a women to return to a healthy lifestyle. For example chemotherapy cause substantial weight loss, diaria, vomiting, anorexia and nausea after chemotherapy. The person may develop anemia, skin disorders, be sun sensitivity and become more vulnerable to every day common infections. The person will most likely lose their hair and substantially loss muscle tone and energy. Another fact about chemotherapy is along with killing cancer cells it may also kill healthy white blood cells that prevent common infections that lead to a weaker immune system. The person will need to take extra caution to avoid any kind of infections. They will also need to be washing their hands frequently, having excellent oral care, avoiding large crowds in areas with pore circulation, staying away from people with infection diseases and just the common cold. Thus returning to a healthy lifestyle will already be extremely challenging process for this person. Nutrition will be at the forefront at helping this person recover rapidly and prevent the reoccurrence of cancer. The person will need to have a relativity...

Australian Initiatives Designed to Reduce the Impact of Testicular Cancer.

...5. Describe the current Australian initiatives designed to reduce the impact of testicular cancer. As my team member has mentioned previously, Australia has very high rate of testicular cancer compared to other developed countries according to Blueseptember.org.au website. Australians are aware of this fact and they have initiatively designed many effective strategies to reduce the impact of testicular cancer on Australians. Apparently, people often feel overwhelmed, scared, anxious and upset after a diagnosis of cancer. These are all normal feelings. Having practical and emotional support during and after diagnosis and treatment for cancer is extremely important. Support may be available from family and friends, health professionals or special support services. There are many hundreds of consumer support and advocacy groups, and cancer charities across Australia. At canceraustralia.gov.au, a website is designed by Australian government, they provide information on Cancer Council Australia which is the nation’s peak non-government cancer control organisation. They work across the cancer spectrum to reduce the impact of cancer on Australians by: • Providing information and support services for patients and families affected by cancer, and advocating for the rights of cancer patients for best treatment and supportive care • Raising awareness and educating Australians about cancer prevention and early detection • Working with and providing information to health......

The Impact on Wealth Growth from Globalization

... The Impact on Wealth Growth from globalization: critical thinking #2 The Impact on Wealth Growth from globalization: critical thinking #2 The Impact on Wealth Growth from Globalization There are a lot of concerns for today’s economy. One of them being wealth distribution. There is the poor, middle class, and the rich. It is evident from the graph shown that the poor are getting richer, the rich are getting richer, and the middle class is getting poorer. So, what is the cause of this? The big answer economist will say is “It Depends”. It depends what factor you look at because there are many. The one I want to focus on is globalization. Is globalization a factor in wealth growth? How is it a factor? Is globalization positive or negative for wealth growth? If anything, what should be done? These are all the question I will try my best to answer in this essay. Globalization VS Wealth Growth Back to the previous question, does globalization effect wealth growth? My answer is, yes. It absolutely effects wealth growth for all nations. Globalization effects a lot of economic studies. For an explanation, let me first define globalization. TechTarget.com defines Globalization as the tendency of businesses, technologies, or philosophies to spread throughout the world, or the process of making this happen. The global economy is sometimes referred to as a globality, characterized as a totally interconnected marketplace, unhampered by time zones or national boundaries.......

Economic Impacts of Going Green

...The Economic Impacts of Going “Green” Mike Miller Economics 201 Professor Gary Reinke University of MD University College May 9, 2007 Abstract The U.S. economy is dependent upon nonrenewable fossil fuels (oil, natural gas and coal) to thrive. Because of this, it faces big problems due to that economy failing and an environment that is being devastated by carbon emissions. This dependency has to stop. Consumer demands for greener products and services are putting increased pressure on businesses and the federal government to be the catalyst in ensuring the change efforts succeed and at the same time help to grow the economy. The environment has become a scarce resource and with that scarcity come impacts to the economy of the United States. According to Van Jones, founder and president of Green for All, two of the biggest problems facing the United States are “a failing economy and a devastated environment.” (Van Jones, 2008, pg 5). Focusing on how the environment is impacting the economy is key to getting on the right track toward solving these problems. The U.S. economy is dependent upon fossil fuels (oil, natural gas and coal) to thrive. All of these fossil fuels, unfortunately, are nonrenewable resources that are in high demand by the American people. When you apply the laws of supply and demand into the equation, scarcity of resources with increasing demand means higher prices to consumers. ......

Corrosion and Biofouling Resistance Evaluation of 90-10 Copper-Nickel

...Corrosion and Biofouling Resistance Evaluation of 90-10 Copper-Nickel Carol Powell Consultant to Copper Development Association, UK. Square Covert, Caynham, Ludlow, Shropshire, UK. Tel 0044 (0)1584 872805, Fax 0044 (0)1584 876632. carol.powell@btinternet.com Abstract Copper-nickel alloys for marine use were developed for naval applications in the early part of the 20th century with a view to improving the corrosion resistance of condenser tubes and seawater piping. They still enjoy widespread use today not only for many navies but also in commercial shipping, floating production, storage and offloading vessels (FPSOs), and in multistage flash desalination. The two popular alloys contain 90% or 70% copper and differ in strength and maximum sea water velocity levels they can handle but it is the 90-10 coppernickel (CuNi10Fe1Mn) which is the more economic and extensively used. An additional benefit of this alloy is its high resistance to biofouling: in recent years this has led to sheathing developments particularly for structures and boat hulls. This paper provides a review of the corrosion and biofouling resistance of 90-10 coppernickel based on laboratory test data and documented experience of the alloy in marine environments. Particular attention is given to exposure trials over 8 years in Langstone Harbour, UK, which have recently been completed by Portsmouth University on behalf of the Nickel Institute. These examined four sheathing products; plate and......
