In Section I of this paper we present an analytical paradigm by which to evaluate health and medical care services in underdeveloped countries. In Section II, we apply this framework to an analysis of the health policies of one developing country, China. In Section III, we evaluate the Chinese health and medical care policies within the framework of a cost‐benefit analysis and argue that these policies are appropriate to China's factor proportions and health needs. Finally, in Section IV, we raise a number of questions to be considered in any more detailed studies on the transferring of the Chinese services to other developing countries.  相似文献

An on-site oral fluid drug screen, Oratect®, was used to investigate the effects of adulterants and foodstuffs on oral fluid test results. Common foods, beverages, food ingredients, cosmetics and hygienic products were demonstrated not to cause false positive results when tested 30 min after their consumption. Evaluations of two commercial oral fluid adulterants, “Clear Choice® Fizzy Flush™” and “Test’in™ Spit n Kleen Mouthwash” suggest their mechanism of action is the clearing of residual drugs of abuse compounds through rinsing of the oral cavity. They do not directly destroy the drug compounds or change the pH of the oral fluid. It is also suggested that a common mouthwash would perform similar action.  相似文献

Are career politician members of parliament (MPs) more or less likely to vote against the party line than their peers? Despite growing interest in the behavior of career politicians across parliamentary systems, answers to this question are marked by considerable theoretical and empirical uncertainty. I derive the two most common (but opposing) behavioral predictions before testing them over all legislative votes of two UK House of Commons terms (2005–15) using multilevel modeling of new and disaggregated data on MPs' occupational backgrounds. The finding that career politicians are more likely to rebel challenges conventional wisdom and provides an important empirical foundation for the ongoing debate.  相似文献

Debates about optimal farm structure and size have a long history in agricultural economics. Agricultural and development economists argue for an inverse relationship between farm size and productivity, but debates around this remain inconclusive. This article provides a case from maize production in Babati District, Tanzania. The efficiency level of 122 sampled smallholder farmers was estimated and found to be 62.3%, suggesting 37.7% of inefficiencies. A U-shape relationship between plot size and efficiency scores was found. There was high efficiency at plots <2?ha, compared to 2?ha and 3?ha, followed by efficiency at plots >4?ha. Policies stimulating small- and large-scale farms in the country are imperative.  相似文献

The primary aims of this article are (a) to examine the importance of cultural norms and what part they play in requiring us to tolerate others out of respect, and (b) to formulate some guidelines designed to prescribe boundaries to liberty and tolerance conducive to safeguard the rights of individuals and, in turn, democracy. I argue that a liberal democracy can interfere in the business of its sub‐cultures when some cultural norms subvert the basic principles upon which a liberal society is founded. I proceed by making a further radical claim that democracy may prevent cultural groups from entering society if their conceptions of the good essentially conflict with its norms. My basic argument is that considerations of context and intentions must be taken into account, and that they may require the introduction of constraints. I conclude by considering the question whether or not the intolerant group has any right to complain, arguing that it does not.1  相似文献
