The Appearances of Power： Its Violent and Popular Geneses According to Machiavelli and La Bo6tie

This paper develops a phenomenology of power in its various forms based on the account of the relationship between domination and freedom given by Niccol6 Machiavelli and ttienne de La Bo6tie. These authors are read in such a way as to extract the contemporary meaning of power in relation to the concept of appearance. Both authors link domination to other forms of violent power （oppression, exploitation, and exclusion）, and while they recognize the inevitable role of appearances in politics, they oppose the tendency of rulers to use appearances to maintain their power over the people. The sharing of intellectual power is then the most likely way for popular power, once it makes its appearance in society, to lead to transformations in governmental and economic power.

Economics of the plant species used in homestead agroforestry on an offshore Sandwip Island of Chittagong District, Bangladesh

This study was performed in five villages of Sandwip Upazila, Chittagong district with a view to identify the tree resources, utilization pattern and economic return of major fruit and timber tree species. Information collected from a total of 60 households ranging from marginal, small, medium and large categories. Number of plant species increased with the increase of homestead area. A total of 33 plant species were recorded from the homegarden, of which 19 were fruit and 14 were timber tree species. Considerable number of vegetables was also planted under the shade of the homestead trees. The investment analysis showed that average benefit-cost ratios were greater than one, net present values were positive and internal rate of returns were more than 10%. Long term investment on horticulture and timber tree species is highly profitable if species like Artocarpus heterophyllus, Cocos nucifera, Tectona grandis and Swietenia macrophylla are planted.

Evaluating Economic and Environmental Benefits of Integrating Solar Photovoltaics within Future Residential Buildings in Saudi Arabia

Renewable energy options, including solar power, are becoming increasingly viable alternatives to conventional sources of energy, such as oil, coal and natural gas. Solar Photovoltaic （PV） technology is one type of solar energy technologies that has recently received substantial attention because it offers the possibility of providing clean power sources for buildings. The aim of this paper is to examine the economic viability of using solar PV within future residential buildings in the oil-rich Saudi Arabia. Strictly speaking, the prospects of using the PV in order to provide 10% of the electricity to be consumed in the houses, which are going to be built in Sandi Arabia over the period 2010-2025, are examined. The study reveals that significant economic and environmental benefits could be realized as a result of such an endeavor.

Economic efficiency in fish farming: hope for agro-allied industries in Niagara

The challenge to increase the efficiency in food production level in Nigeria appears to be more urgent now than it has ever been in the history of the country. This is in view of the rapidly increasing population, the imminent decline in international economic and food aid and the need to conserve foreign exchange earnings through the production of raw materials to feed the growing industrial sector calls for urgent attention. The study was carded out in Ogun State. The descriptive statistics was used to determine the socio-economic characteristics of the respondents. The stochastic frontiers production analysis was applied to estimate the technical, allocative efficiency and economic efficiency among the fish farmers in the state. The results of economic efficiency revealed that fish farming is economically efficient with a range of between 55% and 84% efficiency level suggesting a favourable hope for the agro-allied industry such as poultry and cottage industries etc in the state. The result of hypothesis of inefficiency sources models showed that years of experience of fish farmers is significant at 1% probability level indicating the factor contributing to the fish farming experience in the state. Thus, the efficiency is due to the fact that farmers are experienced and fairly educated. On the basis of findings, policy is suggested to be directed towards the encouragement of entrepreneurs in fish farming in the state by providing enabling environment like credit facilities, public enlightenment programme and provision of social amenities like feeder roads, pipe-born water etc and given the fact that an increase in the level of formal education variable leads to less inefficiency, government policy should be focused on adopting the best technology （e.g. fast growing species and equipment ） so as to improve the level of efficiency and investment which shall eventually lead to growth in output of fish fanning and a lead to the establishment of agro-allied industries in the state.

Current Status of Population Density of Mediterranean Fruit Fly （Ceratitis capitata） in Fruit Orchards in Central Iraq

In the recent years The Mediterranean Fruit fly Ceratitis capitata is distributed in the orchards of central Iraq and caused highly economic losses. This study was conducted in orchards in central Iraq during 2009 and 2010 and made field survey of the insect in four types of orchards （Citrus, Apricot, Figs ＆ Citrus and A mixture of fruit trees） and used for this purpose Tephri Traps supplied with Q-Lure and dimethyl dichloroviny phosphate （DDVP）. The present preliminary study has shown that the Mediterranean fruit fly C. capitata has a year round presence in fruit orchards in central Iraq and reached its highest ntunerical density of the pest in citrus orchards during of November and December were 345 and 363 insect/trap per month in citrus orchards and the least numerical density during of January and February while the highest numerical density of the insect in orchards of Apricot in March 2010, Figs ＆ Citrus in August 2009 and a Mixture of fruit trees in November 2009 were 45, 116, 311 insect/trap per month respectively. The population density of the pest was highest is started 2010 compared with 2009, but the high temperature degree （46-51℃） in August 2010 caused decreasing the population density of this pest. C. capitata caused highly economic losses in citrus reached 68% and 71% of the Mandarin and Kaki fruits respectively Currently in Iraq to fight no control method to reduce the economic losses caused by this pest except the use of pesticides GF-120.

The Future of Sustainability

The focus of the present research is not on expected developments that are by one means or another linked to the concept of sustainability and to questions, whether current sustainability-models are fit for the future, so that they can be employed as corrective or functional factors applicable to the planning and governance of predictable scenarios in the field of ecology, economy, and social issues. But the focus lies on questions like： How does the concept of sustainability relate to the future？ How is the future as such affected and conditioned by the concept of sustainability？ To what extent is the concept of sustainability open to the future and how can the concept of sustainability conceive of something like the future？ The aim of the paper is therefore to clarify and better understand what is at stake when we address a sustainable future, i.e. a future under the conditions of an economy, of a technology, of a science that is supposed to be sustainable. The paper is based on a distinction that has its part in the tradition of ethics with far-reaching consequences for what throughout this tradition was called into question namely： the ethos （the dimension of the human being）. It is the distinction between two aspirant principles. In terms of form, the one allows and sustains accomplishment, whereas the other doesn＇t. As for the former, the reference is mainly to classical ethical positions （on the one hand Plato and Aristotle, on the other hand Kant）. As for the latter, on which the focus of this research lies, a phenomenological analysis of the concept of sustainability might help in its comprehension as well as in the understanding of the way in which we, today, by complying with it, conceive of something like an open future.

Social and Ecological Constraints on Decision Making by Transhumant Pastoralists: A Case Study from the Moroccan Atlas Mountains

Transhumant pastoralism is an important activity in southern Morocco. Migration pattern of transhumant pastoralists can be affected by physical factors (e.g. droughts and diseases) or socioeconomic factors (e.g. schooling options for children and migration costs). We studied the spatio-temporal rangeland usage of the three tribes Ait Mgoun, Ait Zekri, and Ait Toumert in the south-central Atlas region with a two-fold approach. First, we tracked the migration movements of one representative transhumant herd using the Advanced Research and Global Observation Satellite (ARGOS) collars, which record coordinates from satellite signals. Second, we interviewed herders to obtain information about general grazing practices of the respective tribe and to gain more direct information on motivations underlying decisions. For each tribe we observed small-, medium- and large-scale movements. We found that the most important drivers of migration decisions were seasonal fodder availability and weather conditions in combination with herd-specific risk and cost assessment, as well as personal factors. In conclusion, general migration patterns vary in time, both between and within the tribes, but according to a regulatory framework. Moreover, it appears that both the customary rules and its flexible adaptation to physical constraints are generally beneficial in terms of conservation of the arid and semiarid rangeland resources.

Ecological and economical significance of homestead forest to the household of the offshore island in Bangladesh

An explanatory survey was conducted to assess the contribution of plant diversity to the ecological and socio-economic condition of the rural household in the offshore island of Bangladesh. Assessment was done by means of multistage random sampling. The homestead sizes of the study area were classified into 3 groups viz, large （〉0.25 ha）, medium （0.05-0.25 ha） and small （〈0.05 ha） based on the result obtained from a preliminary survey, and a total of 45 homesteads, 15 from each group, were selected randomly for the study. The average annual income from homestead＇s plant diversity varied from Tk 5730.00 （US$95.5） to Tk 17500.00 （US$291.67）. The rural people were mainly dependent on their homegarden for woodfuel and nutritional requirement as forest was unavailable in the island. The rural people here also cultivated the plant species as a safety measure from frequent cyclone. Constraints hindering the development of homestead plantation were identified and suggestions were given such as the adequate supply of seedlings of fast growing native species and conservation of endangered species to meet the demand of the household as well as to keep ecological balance.

Bangladesh Economic Development Model （BED Model）

Bangladesh economy has experienced some stable growths with regard to major macroeconomic indicators, significant progress in social development indicators, rural infrastructure, investment in industrial agricultural sector, and poverty alleviation since the 1990s. Bangladesh has made major strides in its human development index （HDI）, population growth rate achieved to 1.3%, gross domestic product （GDP） over the last five years achieved more than 5% growth consecutively; as a result, it mooted the Brazil, Russia, India, China （BRIC） successors, otherwise known as the Next-11. The success has come through the miracle activities of micro finance （MF： Grameen Bank and non-governmental organizations （NGOs））, remittance from migrant worker （RMW）, and export of readymade garment （ERMG） products. These three （MF, RMW, and ERMG） as the ＂prime powers＂ or engines have been achieving to ＂bottom up＂ of social economic development. This paper reviews aspects of economic development in Bangladesh, analyzes three prime powers, and tries to find out a development pattern, vis-a-vis construct Bangladesh economic development model or BED model. Finally, this paper examines Bangladesh＇s development experience in light of the BED model. It has recognized MF model for poverty alleviation in the worldwide.

Economic Feasibility of Simultaneous Production of Pine Sawlogs and Meat Goats on Small-Sized Farms in Alabama

The objective of this study were to conduct economic evaluations of silvopasture farming system to enable landowners, extension personnel, and other decision makers to correctly assess its potential among the many land-use options; and to determine the most profitable animal stocking rate on small farms in Alabama. The analysis draws on data from a silvopastoral experiment conducted in the Alabama Black Belt region, on the property of the Federation of Southern Cooperatives in Epes, Alabama, between June 2006 and July 2010. Economic and financial ratio analyses were used to compare profitability, management feasibility, and risk considerations of simultaneous production of pine sawlogs and meat goats on small-sized farms in Alabama. The results suggest that silvopasture technology is profitable and financially feasible under specified assumptions. The Net Present Value model suggested that investing in silvopasture system would be considered acceptable at the 6 percent discount rate at a high stocking rate of 8 meat goats per acre. These findings were reaffirmed by the financial feasibility analysis.

A Cost-Benefit Analysis of China＇s Trade Relations With Sub-Saharan Africa

Trade and economic relations between China and Africa have a protracted history and have developed incrementally over the course of time. Consequently, increasing numbers of Chinese businesses and entrepreneurs have sought partnerships with African companies with the aim of establishing strategic partnerships, collaborations, and joint ventures. In recent years, these Sino-African trading relations have been the subject of consistent debate and scrutiny, attracting positive and negative analyses from scholars and practitioners across disciplines. Some studies questioned China＇s motives in Africa＇s markets, and others viewed with suspicion the structure of Sino-Africa＇s bilateral trading engagements. Conducting an extensive literature survey of related sources and employing content analysis of recent and current data （2000-2009）, the paper examined institutional and academic publications pertaining to Sino-African relationship. It determines imbalance in the structure of Sino-African bilateral trade, negative impact on domestic economic development, and competitive disadvantage in African marketplaces. Policy implications of these findings were provided as well as recommendations for mutual trade benefits and global strategic investments

The Relative Deprivation Theory and Yemen＇s Uprising

The political upheavals in the Arab world during 2011 challenged the political status quo and have irrevocably paved the way toward transformation in the Middle East and North Africa （MENA）, The longstanding structural impediments to equitable growth and social justice afflicting the Arab world came to a head through a combination of persistently poverty, high unemployment, particularly among educated youth, rampant corruption, deficit of democratic governance, and essential freedoms. Yemen is the third country of the Middle Eastern countries which turmoil sparked in. All the uprisings connote of social, political and economic discontent and frustration. The main question and issue of this paper is to answer： What conditions breed change to Yemen？ The paper spotlights ＂relative deprivation＂ of Ted Robert Gurr as the most relevant theory to illustrate roots of the Yemen uprising. Relative deprivation theory holds that instead of an absolute standard deprivation, a gap between expectations and reality leads men to political violence. Therefore, this study is to utilize relative deprivation theory to explain how socio-economic shortages （such as high unemployment and education, along with poverty） and political inefficiencies of the Yemen＇s authoritarian regime led to public and collective discontent and upheaval. The intervened variables such as ＂ethnicity, race, religion, and sexuality＂ and international parameters have not been considered,
