To give you an idea of how to write an informative speech on a contemporary issue in the U.S. Education system, here is a quick sample for your review. Sample Informative Speech: How to Reduce, Prevent and Control Violence in School School violence is one of the biggest contemporary issues within the U.S. Educational system. However, teachers, parents, community members and even students can work together to make sure that there is no violence altogether. It is important that they all collaborate as there is not only one factor that triggers violent tendencies. Violent actions should be stopped before they happen because controlling them afterwards can become messier. There have been instances where students have carried weapons in schools and went undetected by metal detectors and security measures. This proves that weapons can make their way to campus easily. Therefore, it is time to demotivate students from becoming violent while providing safety guarantees for others before they begin fearing coming to school. There are various alternate solutions provided by Public Health that have more effective results. For starters, students should be encouraged to join extracurricular activities that can assist them to solve their personal issues in a healthier way rather than becoming violent. School based violence prevention programs can help reduce the aggressive behavior amongst students. These prevention programs must teach students about controlling their emotions, self-awareness, self-esteem, teamwork, how to behave in a society, and conflict resolution. However, it is equally important to prepare and inform students about what to do when a violent altercation occurs between peers. Another reality schools need to face is that violent physical episodes cannot just happen between students. There have been instances where school administrations have winded up getting physically hurt as well. Therefore, school-based prevention programs should not just be subliminal. Students should be bluntly told how a small fight can lead to permanent injuries and even deaths. Teachers play an active role in the fulfillment of these awareness and prevention programs. By building healthy and friendly relationships with their students, teachers can listen to children’s struggles outside of the school and be their pillar of support. This way, violent attitude and behaviors have less room to grow. A responsible teacher who listens to his or her students cannot only make the student’s life easier, but also improve the classroom environment, reduce conflicts, and prevent fights from happening in the school premises. There should be an open channel relationship between the parent and the teacher. If both of them are in sync, they can align their strategies if the child has been showing aggressive tendencies. Both teachers and parents need to assume responsibility if the other is showing negligence. As some parents might find it offensive if they are told that they are not being responsible enough, having monthly workshops about the role of parents in reducing children’s stress for the parents generally can be a better solution. The school itself should be physically altered so that there is accountability at all times. This type of security should be obscured because the idea is to teach the children to be nonviolent, not force them to. The staff should also be told to keep a lookout for altercations, hidden cameras should be placed, and the hedges in the play area should be kept to waist height. You can definitely come up with a better speech if you put your heart into it, so get going and begin informative speech writing right away. References: Hankin A, Hertz M, Simon T.

Before Exams 7 Helpful Memory Improvement Tecniques

Before Exams 7 Helpful Memory Improvement Tecniques Exams often cause a lot of anxiety to students because of the amount of information theyre expected to master in a short time. If youre afraid your memory will fail you during your tests, dont worry. There are several ways you can boost your memory and retention before test day. Here are some great practices that will improve your memory: Get Your Zs While pulling an all-nighter to cram the night before an exam may seem like a good idea, allowing you extra hours of studying, it can actually have a negative effect on your exam outcome. Thats because sleep is an important part of brain function. Your brain actually synthesizes the information it learned during sleep. Sleep also aids in memory formation, allowing you to recall information later. Without these hours of rest and rejuvenation, the brains cognitive abilities are inhibited. Its much more effective for you to get a good nights sleep than to push through until dawn looking over information you may not be able to remember anyway. If you have no choice and need to study at night, at least find out how to study for a test the night before without harming your he Diet Give yourself some healthy brain food before an exam. Dont skip any meals. Eat plenty of fruits, vegetables, lean proteins and omega 3 fatty acids. Some high-power brain foods are: Broccoli and cauliflower Walnuts Chickpeas Red meat Blueberries Olive oil Salmon Avocado Eggs Exercise Getting a bit of exercise before a test is a great way to increase the blood and oxygen flow to the brain. A quick run or bicycle ride in the morning or some jumping jacks, yoga or calisthenics should be enough to get your heart rate up and your blood pumping. Physical exercise is also a great way to boost your mood and overall sense of well-being an ideal state of mind and body to be in before you take your exam. Association A lot of exam studying is memorization, but, unfortunately, memorization is short term, meaning youll likely forget the information soon after you take the test. Learning how to make associations can help you to retain the information for longer. For example, you could make up Acronyms or letter associations for certain concepts such as Please Excuse My Dear Aunt Sally which stands for the order of operations for mathematical problems (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction). Creating a rhyme could also help you remember important names or dates (In 1492, Columbus sailed the ocean blue). More tips on memorizing you can find in our post on how to develop photographic memory. Visualization Visualization is a powerful technique that can be used for all subjects. If youre studying for a History exam, try to imagine the events as they take place. If youve watched a documentary or film about the events, try to incorporate those images into your memory. For a Biology exam, recall the slides of the different specimen you studied. Visualize their movements and behaviors and apply that to the concepts you learned in class. For a math exam, you can visualize equations in their most simple forms and use that to apply to more complicated equations on the exam. Also, you should try the technique of building mind palace (like Sherlock, you know?). Divide and conquer Dont study for all of your exams all at once. Instead, focus on one at a time. By taking one subject and reviewing your notes and using some of the techniques mentioned above, youre creating a specific compartment in your brain for you to recall that information. Mixing all of the information up will cause some confusing cross-referencing when its time to take the exams. See your studying through from start to finish on one subject, allowing some time to review your notes before the big test. Relaxation Probably the worst thing you can do to your exam performance is stress out. A little adrenaline is natural, but going into a downward spiral of negative thinking, anxiety and even hyperventilation will only make things worse. Stress causes your blood vessels to constrict, inhibiting the flow of blood and oxygen throughout the body, including to the brain. Without these necessary elements, the brains function also gets reduced. If you have a tendency to stress out before a big test or exam, try taking some time right before the test to relax. Find a quiet spot, or put on some headphones and listen to some soothing music. Take several long, deep breaths. Search for any tension in your body and see if youre able to relax those tense areas. When the time comes to start the exam, maintain that relaxed state of mind and if you feel yourself tensing up, take deep breaths and remember to relax.

Marxist and Funtionalist Perspectives on Inequality of Educational Essay

Marxist and Funtionalist Perspectives on Inequality of Educational Achievement Due to Social Class - Essay Example At the least, the democratic socialist countries would be expected to have achieved greater educational equality among citizens of distinct class backgrounds. It was found that the Soviet Union has not achieved educational equality to a noticeable extent, based on its characterization as a state capitalist country, deeply divided by class distinctions, and with the state bureaucracy at its core (Liston, 1988). Ramirez (2006) argues that cross-nationally, family background is clearly related to academic achievement; however, there is extensive cross-national variation in the correlation between achievement and aspirations. According to Ream and Palardy (2008), ‘social capital’ forms one of the components of social class which includes material and human capital. The researchers examined how parental social networks divided by class increase educational inequality among school children. Further, the authors used survey data to determine whether â€Å"certain forms of pare ntal social capital create educational advantages for socioeconomically privileged students vis-a-vis their less economically fortunate peers† (Ream and Palardy, 2008, p.238). Distinguishing between the availability of social capital and its convertibility, while greater extents of parental social capital was found to be concurrent with higher rungs in the social class ladder; the utility value of social capital for education was not clearly related to class status. A possible exception to this tendency could be the collective influence of middle-class parents’ ideas on beneficially changing school policies and practices. It is important to investigate whether the economic and sociological reasons for inequality can promote â€Å"educationally useful... As the paper stresses distinguishing between the availability of social capital and its convertibility, while greater extents of parental social capital was found to be concurrent with higher rungs in the social class ladder; the utility value of social capital for education was not clearly related to class status. A possible exception to this tendency could be the collective influence of middle-class parents’ ideas on beneficially changing school policies and practices. It is important to investigate whether the economic and sociological reasons for inequality can promote â€Å"educationally useful social exchange among parents across social boundaries†. This discussion explores that social justice and equity in connection with higher education is an important area of research towards policy formulation. These concepts help to create a more impartial, courteous, and just society for everyone. This conceptualization focuses on society as a whole; however â€Å"higher education research literature looks inward towards higher education itself†. In the social composition of higher education’s staff and student populations, it is found that equity and social justice agendas are imported from the wider society. This approach considers the rules of the competition as unfair if particular social groups are excluded or placed in a disadvantageous position in the competition for higher education. Functionalism is characterised as a set of three interrelatedd theses about the social world.

Gherkin and Pomegranate Cultivation

Gherkin and Pomegranate Cultivation Abstract Horticulture is an important component of agriculture accounting for a very significant share in the Indian economy. Rising consumer income and changing lifestyles are creating bigger markets for high-value horticultural products in India as well as throughout the world. Among these, the most important high-value export products are fruits and vegetables. This study was conducted to analyze the comparative advantage and competitiveness of pomegranate and gherkin which are the important foreign exchange earner among fruit and vegetable crops exported from India. The primary data was collected from Tumkur and Bijapur district of Karnataka, India and secondary data was collected from concerned government institutions, APEDA and also from exporters of fruits and vegetables. The Policy Analysis Matrix (PAM) was selected as the analytical tool to analyse the export competitiveness, comparative advantage, and the degree of government interventions in the production and export of gherkin and pomegranate. The policy distortions were measured through indicators of PAM. Garret ranking technique was used to analyse the constraints in the production and export of the selected crops. EPC of Gherkin (0.5) and pomegranate (0.45) values which found to be less than one indicates that producers are not protected through policy interventions. Whereas DRC (0.27 0.28) and PCR (0.43 0.59) values of Gherkin and Pomegranate respectively shows positive, social as well as private profit which indicates that, India has a competitive and comparative advantage in their production. The result for Garret ranking in case of gherkin shows that skilled labour and lack of superior quality are the major constraints in production and export of gherkin respectively. In case of pomegranate non availability of skilled labour, high incidence of pest and diseases, lack of transportation facilities, high residual effect of pesticide are the major constrain in production and export. The overall result shows that the cultivation as well as export of gherkin and pomegranate is economically profitable and efficient.

Introduction 1.1 Background Indian agriculture is vested with the herculean responsibility of feeding over more than one billion people. Out of total, 72% of Indias population live in rural areas, further three-fourth of the rural populations depend on agriculture and allied activities for their livelihoods. The present growth in agriculture in India is hassle with problems most importantly, agricultural growth slowed down to 2.1% between 1998-99 and 2004-05. It is largely due to a decline in the food grain sector that grew at merely 0.6%. Given the high dependence of the poor on agriculture, the stagnation in this sector is currently threatening to stall poverty reduction in India (Reddy, 2007). Given the present scenario, the immediate question to be addressed is how agricultural growth can be accelerated. The question can be answered through by diversifying the consumption pattern towards high value agricultural commodities in general and high value horticultural products in particular such as fruits and vegetables. In recent years there has been a great deal of interest among policymakers and trade analysts in the role of horticultural products as a principle means of agricultural diversification and foreign exchange earnings in developing countries. Horticultural products have high income elasticity of demand as income goes up the demand raises rapidly. It grows especially in middle and high income developing countries. As people are more cautious on health and nutrition, there is a paradigm shift from high fat, high cholesterol foods such as meat and live stock products to low fat and low cholesterol foods such as fruits and vegetables. As a result, the world has change d its attention towards high value agricultural products. Hence, it is crucial to be competitive in the world market to reap the potential gains of increased and growing world demand for horticultural products such as fruits and vegetables. Thus, the purpose of the present study attempts to evaluate the consequences of international trade and competitiveness of Indian horticulture with special reference to pomegranate and gherkin crops. In the recent past, these two crops got high export potential and earned good foreign exchange. 1.2 Studies on export of fruits and vegetables There are many studies related to export of horticultural crops especially fruits and vegetables from India. Chiniwar (2009) explained the numerous opportunities and challenges of the horticulture sector and observed that there is a tremendous potential for Indian pomegranates in the global market. He examined the growth of pomegranate exports from India. The study revealed that the growth of pomegranate exports from India is moderate in comparision to the potential for its exports. Tamanna et al. (1999) examined the export potential of selected fruits from India by using Nominal Protection Coefficient (NPC). The results indicate that the exports of Indian fruits are highly competitive in the world market. Nalini et al. (2008) observed that India has made tremendous progress in the export of cucumber and gherkin products during the past 15 years (1990-2005). The export has increased by about 129 times with an impressive annual compound growth rate of 37.46 percent, as against only 4. 38 percent in the world market. An increasing and high value of Revealed Comparative Advantage (RCA) and a positive and increasing value for Revealed Symmetric Comparative Advantage (RSCA) have indicated high potential for their export. One percent increase in volume of international trade in cucumber and gherkin may increase the demand from India by 5.96 percent. This indicates that India is highly competitive in the export of cucumber and gherkin. It has ample scope to further increase its export. Gulati et al. (1994) analyzed the export competitiveness of selected agricultural commodities and identified the constraints in the export of fresh fruits, vegetables, processed fruits and vegetables. The above studies are related to export performance, growth, and constraints of fruits and vegetables. Most of these studies focused on aspects pertaining to export of fruits and vegetables. There are no studies on export policy especially related to efficiency and comparative advantage in world market. Therefore, the aim of the present study is to analyze the export competitiveness of pomegranate and gherkin by using Policy Analysis Matrix (PAM). The study has a high scope because competitiveness has become a key issue in the international market for export development of fruits and vegetables. 1.3 Research objectives In the present study, the export competitiveness of high value horticultural crops of India is analyzed. To be very precise, the study analyzes the competitiveness of gherkin and pomegranate in the world market. It also compares the advantages and constraints in the export of these crops with the following objectives and proposed hypothesis, which will be tested based on the results and conclusion. Specific objectives To assess the export competitiveness of Gherkin and Pomegranate To examine the production and export constraints of Gherkin and Pomegranate Hypothesis Export of gherkin and pomegranate are competitive in international markets 1.4 Structure of the thesis The study contains the results of the analysis of export competitiveness of horticultural crops in India. In the present study, opportunities are analyzed, constraints in production and export of gherkins and pomegranates from India. We further analyze the competitiveness and comparative advantage of these two crops in international market. The detailed information of this analysis is discussed in the following sections of the study. The first section of the thesis gives us an introduction and background on the nature of the problem, facts on the dynamics and underlying causes diversifying the consumption pattern of high value horticultural commodities. Further, a brief overview of existing studies on Indian agricultural and horticultural growth, export performance, and constraints will be discussed. The research question is broken down into specific objectives and a possible hypothesis has been put forth. The second section of the thesis will give a general overview of fruit and vegetable scenario in the world as well as in India. The section also explains the importance of selected fruit and vegetable by considering production, export and foreign exchange earnings which will help us to understand the export competitiveness of these crops from India. The third section deals with methodological framework which deals with the concepts and competitiveness of high value horticultural crops from India focusing on the application of PAM model for the study. In the same chapter, the current literature and outline of the major definitions for competitiveness and comparative advantage are studied. The above proposed model will be used as a tool to address the research objectives followed by data description. Fourth section highlights the findings of the research from the proposed model using collected information on pomegranate and gherkin cultivation, and their export. Finally, the proposed hypothesis is tested and the results inferred. The final section summarizes the whole research findings and provides meaningful policy implications. 2. Scenario of fruits and vegetables in India and the world 2.1 World scenario of fruits and vegetables 2.1.1 High value agricultural production Rising consumer income and changing lifestyles are creating bigger markets for high value agricultural products throughout the world. Among these, the most important high value export sector is horticulture, especially fruits and vegetables. The growing markets for these products present an opportunity for the farmers of developing countries to diversify their production out of staple grains and raise their income. Annual growth rates on the order of 8 to 10 percent in high value agricultural products is promising development (Fig.1), as the production, processing and marketing of these products create a lot of needed employment in rural areas. The rapid growth in high value exports has been part of fundamental and broad reaching trend towards globalization of the agro food system. Dietary changes, trade reform and technical changes in the food industry have contributed to the growth of high value agriculture and trade (World Bank, 2008). 2.1.2 World production of fruit and vegetables The production of fruit and vegetables all over the world grew by 30 percent between 1980 to 1990 and by 56 percent between 1990 to 2003. Much of this growth occurred in China where production grew up by 134 percent in 1980 and climbed to 200 percent by 1990 (UNFAO 2003). At present the world production of fruits and vegetables reached to 512 MT and 946.7MT respectively (Table 1 5). Vegetables: China is currently the worlds largest producer of vegetables, with the production 448.9 MT with an area of 23.9 MHA (47%) (Table 1), whereas India is in the 2nd position with the production of 125.8 MT with an area of 7.8 MHA (13%) followed by USA (4%), Turkey (3%) etc (Indian Horticulture Database, 2008) (Fig.2). Among the vegetable crops gherkin is considered for the study as it is one of the most important vegetable all over the world. Table 2 shows the international production of cucumber and gherkin from different parts of the world during 2007-08. China, Turkey, Iran, Russia and USA are the world largest producers of cucumber and gherkin (Table 3), whereas India position in the production is 34th but it reached 1st (Table 3) and 55th (Table 4) position in export of provisionally preserved and fresh cucumber gherkin respectively.

Table 5 shows the largest fresh fruit producers from different countries during 2007-08. China is the worlds largest fruit producer, producing 19 percent of the world fruits. India ranks second in the list of world producer accounting 12 percent of the worlds production followed by Brazil, where 7 percent of the worlds fruit was grown. (Figure 3) As production is increasing in China at alarming rate compare to other top producing countries. Production growth almost averaged 6 percent per year in China, while production growth in India averaged 2.73 percent per year. The EU experienced the lower annual growth rate of 0.89 percent. Whereas, the production in USA and Brazil has been relatively constant over the period, with average annual growth rates of 0.61 percent for the former and 0.34 percent for the later. Other countries Mexico, South Africa and Chile have experienced slightly higher av erage annual production growth rates of 2.12, 2.56 and 1.3 percent respectively over the same period (FAOSTAT 2008). Among all fruits pomegranate is considered for the present study. Figure 4 shows India is the world largest producer of pomegranate with 900 MT (36%) followed by Iran (31%), Iraq (3%), USA (4%) etc. Over the years Indias export rate for pomegranate has grown steadily to worth of INR0.61 million (US$13741) in 2007-08 with the share of 1.2 percent (Table 6).

Horticulture is an important component of agriculture accounting for a very significant share in the Indian economy. It is identified as one of the potential sector for harnessing Indias competitive advantage in international trade. Further it prepares India to achieve an overall trade target of 1% or more in the share of world trade. Meanwhile, making the country self-sufficient in the last few decades, horticulture has played a very significant role in earning foreign exchange through export. Horticultural crops cover approximately 8.5 percent of total cropped area (20 MHA) (Table 7) with annual production of 207 MT, and productivity of 10.3 MT per hectare during the year 2007-08 (FAO Indian Horticulture Database 2008). Among the horticultural crops fruits and vegetables play an important role, whereas exports of fruits and vegetables have increased over the years (Table 8).

Indias export of gherkin has been steadily increased since 1997-98. It accounts for 24,490 tonnes of gherkins having an export potential of INR 50.27 crore as against 35,242 tonnes worth of INR 69.86 crore in 1999-2000 (Venkatesh, 2003). In recent year gherkin export has been increased to 61.5 million tonnes with a trade value of INR1465.5 million during 2007-08 (UNFAO Export Data, 2009). 2.2.1 Production and export importance of gherkin in India Gherkin crop is being selected for the present study. It is regarded as HEIA crop especially a hybrid crop. Gherkin cultivation and processing started in India in the early 90s and presently cultivated over 19,500 acres in the three southern states of Karnataka, Tamil Nadu and Andhra Pradesh. Although gherkin can grow virtually in any part of the country, the ideal conditions required for growth prevail in these three states where the growing season extends throughout the year. It requires adequate water and temperature between 15-36 degree centigrade and the right type of soil. The crop takes 85 days to reach the required maturity level. Productivity is approximately four to five tonnes per acre and the best months are from February to March followed by June to August. India is a major exporter of provisionally preserved gherkin. Table 10 11 shows the cucumber and gherkin export from India. In India, Karnataka stands first in export, where cultivation is steadily growing since 2001 -02 accounting for a worth of INR 1200 million. During 2006-07 gherkins accounts to INR 3133 million which has been exported (Table 12).

Rising consumer income and changing lifestyles are creating bigger markets for high-value horticultural products in India as well as throughout the world. Among these, the most important high-value export products are fruits and vegetables. This study was conducted to analyze the comparative advantage and competitiveness of pomegranate and gherkin which are the important foreign exchange earner among fruit and vegetable crops exported from India. The primary data was collected from Tumkur and Bijapur district of Karnataka, India and secondary data was collected from concerned government institutions, APEDA and also from exporters of fruits and vegetables. The Policy Analysis Matrix (PAM) was selected as the analytical tool to analyse the export competitiveness, comparative advantage, and the degree of government interventions in the production and export of gherkin and pomegranate. The policy distortions were measured through indicators of PAM. Garret ranking technique was used to analyse the constraints in the production and export of the selected crops. EPC of Gherkin (0.5) and pomegranate (0.45) values which found to be less than one indicates that producers are not protected through policy interventions. Whereas DRC (0.27 0.28) and PCR (0.43 0.59) values of Gherkin and Pomegranate respectively shows positive, social as well as private profit which indicates that, India has a competitive and comparative advantage in their production. The result for Garret ranking in case of gherkin shows that skilled labour and lack of superior quality are the major constraints in production and export of gherkin respectively. In case of pomegranate non availability of skilled labour, high incidence of pest and diseases, lack of transportation facilities, high residual effect of pesticide are the major constrain in production and export. The overall result shows that the cultivation as well as export of gherkin and pomegranate is economically profitable and efficient.

Introduction 1.1 Background Indian agriculture is vested with the herculean responsibility of feeding over more than one billion people. Out of total, 72% of Indias population live in rural areas, further three-fourth of the rural populations depend on agriculture and allied activities for their livelihoods. The present growth in agriculture in India is hassle with problems most importantly, agricultural growth slowed down to 2.1% between 1998-99 and 2004-05. It is largely due to a decline in the food grain sector that grew at merely 0.6%. Given the high dependence of the poor on agriculture, the stagnation in this sector is currently threatening to stall poverty reduction in India (Reddy, 2007). Given the present scenario, the immediate question to be addressed is how agricultural growth can be accelerated. The question can be answered through by diversifying the consumption pattern towards high value agricultural commodities in general and high value horticultural products in particular such as fruits and vegetables. In recent years there has been a great deal of interest among policymakers and trade analysts in the role of horticultural products as a principle means of agricultural diversification and foreign exchange earnings in developing countries. Horticultural products have high income elasticity of demand as income goes up the demand raises rapidly. It grows especially in middle and high income developing countries. As people are more cautious on health and nutrition, there is a paradigm shift from high fat, high cholesterol foods such as meat and live stock products to low fat and low cholesterol foods such as fruits and vegetables. As a result, the world has change d its attention towards high value agricultural products. Hence, it is crucial to be competitive in the world market to reap the potential gains of increased and growing world demand for horticultural products such as fruits and vegetables. Thus, the purpose of the present study attempts to evaluate the consequences of international trade and competitiveness of Indian horticulture with special reference to pomegranate and gherkin crops. In the recent past, these two crops got high export potential and earned good foreign exchange. 1.2 Studies on export of fruits and vegetables There are many studies related to export of horticultural crops especially fruits and vegetables from India. Chiniwar (2009) explained the numerous opportunities and challenges of the horticulture sector and observed that there is a tremendous potential for Indian pomegranates in the global market. He examined the growth of pomegranate exports from India. The study revealed that the growth of pomegranate exports from India is moderate in comparision to the potential for its exports. Tamanna et al. (1999) examined the export potential of selected fruits from India by using Nominal Protection Coefficient (NPC). The results indicate that the exports of Indian fruits are highly competitive in the world market. Nalini et al. (2008) observed that India has made tremendous progress in the export of cucumber and gherkin products during the past 15 years (1990-2005). The export has increased by about 129 times with an impressive annual compound growth rate of 37.46 percent, as against only 4. 38 percent in the world market. An increasing and high value of Revealed Comparative Advantage (RCA) and a positive and increasing value for Revealed Symmetric Comparative Advantage (RSCA) have indicated high potential for their export. One percent increase in volume of international trade in cucumber and gherkin may increase the demand from India by 5.96 percent. This indicates that India is highly competitive in the export of cucumber and gherkin. It has ample scope to further increase its export. Gulati et al. (1994) analyzed the export competitiveness of selected agricultural commodities and identified the constraints in the export of fresh fruits, vegetables, processed fruits and vegetables. The above studies are related to export performance, growth, and constraints of fruits and vegetables. Most of these studies focused on aspects pertaining to export of fruits and vegetables. There are no studies on export policy especially related to efficiency and comparative advantage in world market. Therefore, the aim of the present study is to analyze the export competitiveness of pomegranate and gherkin by using Policy Analysis Matrix (PAM). The study has a high scope because competitiveness has become a key issue in the international market for export development of fruits and vegetables. 1.3 Research objectives In the present study, the export competitiveness of high value horticultural crops of India is analyzed. To be very precise, the study analyzes the competitiveness of gherkin and pomegranate in the world market. It also compares the advantages and constraints in the export of these crops with the following objectives and proposed hypothesis, which will be tested based on the results and conclusion. Specific objectives To assess the export competitiveness of Gherkin and Pomegranate To examine the production and export constraints of Gherkin and Pomegranate Hypothesis Export of gherkin and pomegranate are competitive in international markets 1.4 Structure of the thesis The study contains the results of the analysis of export competitiveness of horticultural crops in India. In the present study, opportunities are analyzed, constraints in production and export of gherkins and pomegranates from India. We further analyze the competitiveness and comparative advantage of these two crops in international market. The detailed information of this analysis is discussed in the following sections of the study. The first section of the thesis gives us an introduction and background on the nature of the problem, facts on the dynamics and underlying causes diversifying the consumption pattern of high value horticultural commodities. Further, a brief overview of existing studies on Indian agricultural and horticultural growth, export performance, and constraints will be discussed. The research question is broken down into specific objectives and a possible hypothesis has been put forth. The second section of the thesis will give a general overview of fruit and vegetable scenario in the world as well as in India. The section also explains the importance of selected fruit and vegetable by considering production, export and foreign exchange earnings which will help us to understand the export competitiveness of these crops from India. The third section deals with methodological framework which deals with the concepts and competitiveness of high value horticultural crops from India focusing on the application of PAM model for the study. In the same chapter, the current literature and outline of the major definitions for competitiveness and comparative advantage are studied. The above proposed model will be used as a tool to address the research objectives followed by data description. Fourth section highlights the findings of the research from the proposed model using collected information on pomegranate and gherkin cultivation, and their export. Finally, the proposed hypothesis is tested and the results inferred. The final section summarizes the whole research findings and provides meaningful policy implications. 2. Scenario of fruits and vegetables in India and the world 2.1 World scenario of fruits and vegetables 2.1.1 High value agricultural production Rising consumer income and changing lifestyles are creating bigger markets for high value agricultural products throughout the world. Among these, the most important high value export sector is horticulture, especially fruits and vegetables. The growing markets for these products present an opportunity for the farmers of developing countries to diversify their production out of staple grains and raise their income. Annual growth rates on the order of 8 to 10 percent in high value agricultural products is promising development (Fig.1), as the production, processing and marketing of these products create a lot of needed employment in rural areas. The rapid growth in high value exports has been part of fundamental and broad reaching trend towards globalization of the agro food system. Dietary changes, trade reform and technical changes in the food industry have contributed to the growth of high value agriculture and trade (World Bank, 2008). 2.1.2 World production of fruit and vegetables The production of fruit and vegetables all over the world grew by 30 percent between 1980 to 1990 and by 56 percent between 1990 to 2003. Much of this growth occurred in China where production grew up by 134 percent in 1980 and climbed to 200 percent by 1990 (UNFAO 2003). At present the world production of fruits and vegetables reached to 512 MT and 946.7MT respectively (Table 1 5). Vegetables: China is currently the worlds largest producer of vegetables, with the production 448.9 MT with an area of 23.9 MHA (47%) (Table 1), whereas India is in the 2nd position with the production of 125.8 MT with an area of 7.8 MHA (13%) followed by USA (4%), Turkey (3%) etc (Indian Horticulture Database, 2008) (Fig.2). Among the vegetable crops gherkin is considered for the study as it is one of the most important vegetable all over the world. Table 2 shows the international production of cucumber and gherkin from different parts of the world during 2007-08. China, Turkey, Iran, Russia and USA are the world largest producers of cucumber and gherkin (Table 3), whereas India position in the production is 34th but it reached 1st (Table 3) and 55th (Table 4) position in export of provisionally preserved and fresh cucumber gherkin respectively.

Table 5 shows the largest fresh fruit producers from different countries during 2007-08. China is the worlds largest fruit producer, producing 19 percent of the world fruits. India ranks second in the list of world producer accounting 12 percent of the worlds production followed by Brazil, where 7 percent of the worlds fruit was grown. (Figure 3) As production is increasing in China at alarming rate compare to other top producing countries. Production growth almost averaged 6 percent per year in China, while production growth in India averaged 2.73 percent per year. The EU experienced the lower annual growth rate of 0.89 percent. Whereas, the production in USA and Brazil has been relatively constant over the period, with average annual growth rates of 0.61 percent for the former and 0.34 percent for the later. Other countries Mexico, South Africa and Chile have experienced slightly higher av erage annual production growth rates of 2.12, 2.56 and 1.3 percent respectively over the same period (FAOSTAT 2008). Among all fruits pomegranate is considered for the present study. Figure 4 shows India is the world largest producer of pomegranate with 900 MT (36%) followed by Iran (31%), Iraq (3%), USA (4%) etc. Over the years Indias export rate for pomegranate has grown steadily to worth of INR0.61 million (US$13741) in 2007-08 with the share of 1.2 percent (Table 6).

Horticulture is an important component of agriculture accounting for a very significant share in the Indian economy. It is identified as one of the potential sector for harnessing Indias competitive advantage in international trade. Further it prepares India to achieve an overall trade target of 1% or more in the share of world trade. Meanwhile, making the country self-sufficient in the last few decades, horticulture has played a very significant role in earning foreign exchange through export. Horticultural crops cover approximately 8.5 percent of total cropped area (20 MHA) (Table 7) with annual production of 207 MT, and productivity of 10.3 MT per hectare during the year 2007-08 (FAO Indian Horticulture Database 2008). Among the horticultural crops fruits and vegetables play an important role, whereas exports of fruits and vegetables have increased over the years (Table 8). During 2004-05 export of fruits and vegetables was INR 13637.13 million as against INR 24116.57 million during 2006-07 (APEDA, 2008) Table 7 Area, production and productivity of horticultural crops in India Year Area (MHA) Production (MT) Productivity (MT/ha) ) 2001-02 16.6 145.8 8.8 2002-03 16.3 144.4 8.9 2003-04 19.2 153.3 21 2004-05 21.1 170.8 8.1 2005-06 18.7 182.8 9.8 2006-07 19.4 191.8 9.9 2007-08 20.1 207.0 10.3 Source: FAO Indian Horticulture Database (2008) Table 8 Export of horticultural produce in India Products 2004-05 2005-06 2006-07 Quantity Value Quantity Value Quantity Value Floriculture seeds 34496 2871 42659 3922 50048 7713 Fresh Fruits vegetables 1296530 13637 1465040 16587 1983873 24117 Processed fruits vegetables 325293 9614 501826 13595 549949 17316 Total 1656319 261227 2009525 341051 258387 491459 Source: APEDA, India Note: Qty: MT, value : Million INR Vegetables: In vegetable production, India is next to China with a production of 125.8 million tonnes from 7.8 million hectares with a share of 13 percent in relation to world production (Table 9).

Nano Chemistry Essay

1.1 Definition Nanochemistry is concerned with generating and altering chemical systems, which develop special and often new effects as a result of the laws of the nanoworld. The bases for these are chemically active nanometric units such as supramolecules or nanocrystals. Nanochemistry looks set to make a great deal of progress for a large number of industry sectors. Nanotechnology exists in the realm where many scientific disciplines meet. Achievements in physics are getting progressively smaller – from valves to electronics, down to microelectronics and quantum computing. It mirrors the downsizing in focus in the biological sciences, from cells to genomics. Conversely, achievements in chemistry have been converging into the nanometre range from below – from atoms and molecules to supramolecular chemistry. Nanochemisty focuses on the unique properties of materials in the 1–100 nm scale. The physical, chemical, electrical, optical and magnetic properties of these materialsare all significantly different from both the properties of the individual building blocks (individual atoms or molecules), and also from the bulk materials.Nanochemistry is a truly multidisciplinary field, forming a bridge between nanotechnology and biotechnology, spanning the physical and life sciences. The Nanochemistry Research Institute (NRI) at Curtin carries out world-class research to provide innovative solutions to – energy and resources – materials and manufacturing – electronics – agricultural – environmental management, and – health and medical industries Nanochemistry applications in the materials, resources and energy sectors range from the design of crystalline catalysts and the control of crystal size, morphology, phase and purity, to the design and use of additives to control crystallization and inhibit scale formation. In the biological field, control of chemistry at the supramolecular level can lead to the development of a wide variety of new and improved biomaterials, such as artificial bones and tissues, as well as new pharmaceuticals and improved methods of drug delivery.1 ENGINEERING, SCIENCE ‘‘We are like dwarfs on the shoulders of giants, so that we can see more than they.’’ Bernard of Chartres, 12th century with nanoscience being the discipline concerned with making, manipulating and imaging materials having at least one spatial dimension in the size range 1–1000 nm and nanotechnology being a device or machine, product or process, based upon individual or multiple integrated nanoscale components, then what is nanochemistry? In its broadest terms, the de.ning feature of nanochemistry is the utilization of synthetic chemistry to make nanoscale building blocks of different size and shape, composition and surface structure, charge and functionality. These building blocks may be useful in their own right. Or in a self-assembly construction process, spontaneous, directed by templates or guided by chemically or lithographically de.ned surface patterns, they may form architectures that perform an intelligent function and portend a particular use.2 1.2 Objective of nanochemistry – Creating nanoparticles – Allowing properties of nanosystems to evolve, manipulating and controlling them – Encapsulating and transporting materials (e.g. deodorant with nanodroplets)4 1.3 Nanochemistry used in: – – Cosmetics, e.g. sunscreen, toothpaste, skincare products – Sanitary ware – Built-in ovens and baking trays – Gas-tight packaging – Screens, photographic films – Separating technology for waste water treatment and food production – Catalysers for chemical reactions – Exhaust purification5 It is also used in formation of :- – Commercialization of nanochemicals – Nanooxides of precious, ferromagnetic, rare metals (Ti, Zr etc.) Nanopolymers and membranes – Nanomaterials (cement, fertilizers) – Nanopowders in chemical applications – Nanogreen chemistry – Nano energy applications – Environmental applications of nanotechnology When thinking about self-assembly of a targeted structure from the spontaneous organization of building blocks with dimensions that are beyond the sub-nanometer scale of most molecules or macromolecules, there are five prominent principles that need to be taken into consideration. These are: (i) building blocks, scale, shape, surface structure, (ii) attractive and repulsive interactions between building blocks, equilibrium separation, (iii) reversible association–dissociation and/or adaptable motion of building blocks in assembly, lowest energy structure, (iv) building block interactions with solvents, interfaces, templates, (v) building-blocks dynamics, mass transport and agitation. A challenge for perfecting structures made by this kind of self-assembly chemistry is to .nd ways of synthesizing (bottom-up) or fabricating (top-down) building blocks not only with the right composition but also having the same size and shape. No matter which way building blocks are made they are never truly monodisperse, nless they happen to be single atoms or molecules. There always exists a degree of polydispersity in their size and shape, which is manifest in the achievable degree of structural perfection of the assembly and the nature and population of defects in the assembled system. Equally demanding is to make building blocks with a particular surface structure, charge and functionality. Surface properties will control the interactions between building blocks as well as with their environment, which ultimately determines the geometry and distances at which building blocks come to equilibrium in a self-assembled system. Relative motion between building blocks facilitates collisions between them, whilst energetically allowed aggregation deaggregation processes and corrective movements of the self-assembled structure will allow it to attain the most stable form. 6 Providing the building blocks are not too strongly bound in the assembly it will be able to adjust to an orderly structure. If on the other hand the building blocks in the assembly are too strongly interacting, they will be unable to adjust their relative positions within the assembly and a less 1 ordered structure will result. Dynamic effects involving building blocks and assemblies can occur in the liquid phase, at an air/liquid or liquid/liquid interface, on the surface of a substrate or within a template co-assembly. As this text describes, building blocks can be made out of most known organic, inorganic, polymeric, and hybrid materials. Creative ways of making spheres and cubes, sheets and discs, wires and tubes, rings and spirals, with nm to cm dimensions, abound in the materials self-assembly literature. They provide the basic construction modules for materials self-assembly over all scales, a new way of synthesizing electronic, optical, photonic, magnetic materials with hierarchical structures and complex form, which is the central theme running throughout this chapter. A .owchart describing these main ideas is shown in igure 1. Nano-, a pre.x denoting a factor, its origin in the Greek nanos, meaning dwarf. The term is often associated with the time interval of a nanosecond, a billionth of a second, and the length scale of a nanometer, a billionth of a meter or 10 A  ° . In its broadest terms, nanoscience and nanotechnology congers up visions of making, imaging, manipulating and utilizing things really small. Feynman’s prescient nano world ‘‘on the head of a pin’’ inspires scientists and technologists to venture into this uncharted nano-terrain to do something big with something small.7 1.4 Large and Small Nanomaterials It was not so long ago in the world of molecules and materials that 1 nm (1 nm  ¼ 10 A  ° ) was considered large in chemistry while 1 m m (1 m m  ¼ 1000 nm  ¼ 10,000 A  ° ) was considered small in engineering physics. Matter residing in the ‘‘fuzzy interface’’ between these large and small extremes of length scales emerged as the science of nanoscale materials and has grown into one of the most exciting and vibrant fields of endeavor, showing all the signs of having a revolutionary impact on materials as we know them today. In our time, ‘‘nano’’ has left the science reservation and entered the industrial technology consciousness and public and political perception. Indeed, bulk materials can be remodeled through bottom-up synthetic chemistry and top-down engineering physics strategies as nanomaterials in two main ways, the first by reducing one or more of their physical dimensions to the nanoscale and the second by providing them with nanoscale porosity. When talking about finely divided and porous forms of nanostructured matter, it is found that ‘‘nanomaterials characteristically exhibits physical and chemical properties different from the bulk as a consequence of having at least one spatial dimension in the size range of 1–1000 nm’’.

The Problem And Its Impact On Teen Pregnancy - 3184 Words

THE PROBLEM AND ITS IMPACT Teen Pregnancy in the United States Teen pregnancy in the United States has been an ongoing issue for well over 50 years. The United States ranks first amongst developed countries in teen pregnancy rates (See Table 2). Approximately 750,000 teenage girls between ages 15 and19 will become pregnant every year (Do Something.org, 2014). Statistics show that of the teen population that will become pregnant annually, only a small percentage complete their high school education, much less fulfill a college degree. In fact, about 38% of teenage mothers who have a child before the age of 18 will obtain a high school diploma (The National Campaign, 2014). In addition, less than 2% of young mothers (those who had a child before age 18) will obtain a college degree by age 30 (Why it Matters, 2012). Contributing Factors of Teen Pregnancies There are various factors that contribute to increased teenage pregnancies in the United States such factors include: race, ethnicity and socioeconomic status. However, low socioeconomic status corresponding with single marital status is determined to be a frequent risk factor for teenage pregnancy. Teenage pregnancy has also been correlated with increased poverty rates for young mothers; this is especially true for single mothers. Studies have determined that un-wed-single teenage mothers are more likely than their childless peers to be impoverished during their lifetime. Overall, population studies have estimated thatShow MoreRelatedTeen Pregnancy1426 Words   |  6 PagesIntroduction Teen pregnancy is often unplanned and challenging for the future life of mother and child.
