Home gardens have been an integral part of the recent food-based interventions aimed at stimulating changes in dietary patterns and improving nutrition. However, evidence of their effects on food security, dietary quality, child anthropometry and incomes is limited, particularly among vulnerable populations groups. Using panel data from a sample of approximately 1900 households from vulnerable population groups in Odisha, India, difference-in-differences and other econometric techniques, we analyse the effects of home gardens on food security, dietary quality, child anthropometry and income. On average, home gardens contribute to better household food security, higher dietary quality of men and women but do not contribute to higher children's dietary quality and anthropometry. Also, home gardens increase monthly per adult equivalent incomes by 37% and reduce the prevalence of poverty by 11.7 percentage points. Quantile regression results suggest that home gardens enhance food security and incomes in all quantiles, but richer farmers benefit more than poorer farmers. Overall, home gardens can enhance household food security, dietary quality of men and women, and income gains among vulnerable farming population groups, but they may not suffice to improve child dietary quality and anthropometry.  相似文献

The economic incentives facing people making decisions about infectious disease control have been given due theoretical consideration in the literature, based on principles of economic rationality. Such deductive models provide important tools for generating hypotheses. However, the application of such models in a predictive capacity has been criticised. Simultaneously, empirical studies aimed at quantitative exploration of farmer behaviour have relied heavily on social cognitive models, such as the theory of planned behaviour, without exploration of the epidemiological consequences of variability in behaviour within populations. Advances in other social sciences have revealed systematic biases in human reasoning which cast doubt on the validity of the rational economic model as a generalisation of human decision making. We review the characteristics of infectious disease and disease‐control interventions and the potential for bias in implementation decision making at primary producer level. Specific focus is given to the generation of externalities, both positive and negative; the perception of risk, relating to disease incidence, technology adoption and time preference; and finally uncertainty, and its potential to be moderated by trust in information sources. This information is then used to summarise supplemental psychological constructs which taken holistically may strengthen our ability to quantitatively explore human behaviour in this complex decision‐making environment.  相似文献

This paper applies Albert Hirschman's exit-voice framework to the problems of education coverage and quality in Latin America. It argues that the combination of low direct taxation and high levels of private primary enrolment provides exit options for the wealthy and reduces their incentive to exercise their “voice”, or protest mechanisms, in the face of poor education performance. It also argues that fragmented and clientelist political party structures limit the provision and monitoring of public education, and also reduce the political capacity of the poor to exercise their voice regarding public education coverage and quality. The main policy implication of the paper is that good governance in education cannot realistically be addressed without analysing how the structure of power and voice, and of conflicts of interest within civil society, affect the actual political pressures that state institutions face.  相似文献

Abstract

This paper explores the linkages between structural adjustment and the liberalization of agricultural marketing in sub‐Saharan Africa (SSA). It examines the nature of structural problems, which have been manifested in stagnating output and balance of payments difficulties. Policy responses are described, in terms of short term macroeconomic stabilization and longer term growth‐oriented adjustment policies. The process of structural adjustment in Africa is surveyed, and policies and stages in the liberalization of markets are considered. Debates on agricultural marketing in SSA are reviewed. This leads into an analysis of the specific issues which arise while marketing policy reform proceeds as an integral part of structural adjustment strategies.  相似文献

Nanotechnologies and nanoscience have generated an unprecedented global research and development race involving dozens of countries. The understanding of associated environmental, ethical, and societal implications lags far behind the science and technology. Consequently, it is critical to consider both what is known and what is unknown to offer a kernel that future work can be added to. The challenges presented by nanotechnologies are discussed. Some initial solutions such as self-regulation and borrowing techniques and tools from other fields are accompanied by a call for further research.  相似文献

The ongoing cynicism about leaders and organizations calls for a new standard of ethical leadership that we have labeled ??transformative leadership.?? This new leadership model integrates ethically-based features of six other well-regarded leadership perspectives and combines key normative and instrumental elements of each of those six perspectives. Transformative leadership honors the governance obligations of leaders by demonstrating a commitment to the welfare of all stakeholders and by seeking to optimize long-term wealth creation. Citing the scholarly literature about leadership theory, we identify key elements of the six leadership perspectives that make up transformative leadership, suggest leaders who exemplify each perspective, describe the ethical foundations and message of each perspective, and offer ten propositions that scholars and practitioners can use to test the dimensions of this new transformative leadership model.  相似文献

With cach successive generation of management, managers have been faced with different goals dictated by that current society's needs and mores. For example, in the early 1900's, industrial growth was essential to society's needs; at the same time, such growth would not be hampered by social costs that were perceived as unimportant. Those social costs viewed as unimportant have not been properly factored into the cost of goods produced. Therefore, the products sold were underpriced, failing to reflect their true social costs. Additionally, this miscalculation or misappropriation of such costs caused a misallocation of resources, such as the manufacturing of asbestos without regard to future health costs. Finally, the payment for the miscalculation of these social costs is due: present day management is now forced to provide a viable solution for payment of debts incurred by previous management. The most notable examples of such misappropriation are provided in the Manville, A. H. Robins and Continental cases. Unfortunately, the choice is often limited to a Chapter 11 bankruptcy.This article views the solution of Chapter 11 bankruptcy from three perspectives: legal, managerial, and moral. The legal review consists of the law and the current jurisprudence. Particularly emphasized are cases dealing with the discharge of executory contracts, tort claims and debts both secured and unsecured. Additionally, an examination of implementing a Chapter 11 bankruptcy plan from the viewpoint of current management is made. Closely associated with both the legal and managerial aspects of this issue is the moral facet of using bankruptcy as a management tool. The broad question is: how prevalent and how reasonable is it for management to declare Chapter 11 bankruptcy to manipulate the corporation's creditors, employees, and stockholders to achieve management's desired end.Professor Hogg currently teaches Managerial Perspectives and Business Law at the A. B. Freeman School of Business, Tulane University. In addition, he is an adjunct faculty member at the Joseph A. Butt, S. J. College of Business Administration, Loyola University, New Orleans, Louisiana, where he teaches courses on Business Ethics and the Legal and Regulatory Environment of Business. Also, he has received several awards for excellence in teaching. His primary research is in the field of Business Ethics.Dinah Payne is licensed to practice law in the state of Louisiana. She has given a number of presentations, including a recent Continuing Legal Education Program on the use of bankruptcy as a management tool. Dr. Payne has also published articles in a number of journals, includingJournal of Business Ethics, Labor Law Journal, Managerial Accounting, andAccounting Today. She has been teaching at UNO since 1988.  相似文献
