Difficulties have been encountered in attempting to apply benefit-cost analysis to the problem of determining resource allocations among social programs, especially when there are multiple outcomes associated with each of the programs. Further complications result when program outcomes are characterized as counteractive: a specific allocation of resources to a program is likely to achieve a favorable impact regarding certain objectives while that allocation is also likely to have an unfavorable impact regarding other objectives. A model which promises to be useful in determining optimal resource allocations among programs having counteractive outcomes is presented. Two steps are required for the use of the model: (1) values, reflecting priorities, need to be assigned to the various objectives that programs are intended to accomplish and (2) an ensemble of probabilistic functions relating resources to program outcomes needs to be specified and combined to reflect the value of an ensemble of programs. In addition to determining optimal resource allocations, the model provides insights into the consequences of resource decisions based on noneconomic considerations. An example illustrates the major features of the model. 相似文献

A decade of spectacular progress in functional magnetic resonance imaging (fMRI) technology and systems neuroscience research has so far yielded few changes in our daily lives. The dearth of clinical applications of this prolific and academically promising research tool began raising the eyebrows of the public and the research funding agencies. This may be one of the reasons for the enthusiasm and interest paid to the growing body of literature suggesting that blood oxygenation level‐dependent (BOLD) fMRI of the brain could be sensitive to the differences between lie and truth. The word ‘differences’ is critical here since it refers to the often‐ignored core concept of BOLD fMRI: it is only sensitive to differences between two brain states. Thus, available studies report using fMRI to discriminate between lie and truth or some other comparative state rather than to positively identify deception. This nuance is an example of the extent to which applied neuroscience research does not lend itself to the type of over‐simplification that has plagued the interpretation of fMRI‐based lie detection by the popular press and the increasingly vocal academic critics. As an early contributor to the modest stream of data on fMRI‐based lie detection, I was asked by Dr Aldert Vrij to write a piece in favour of fMRI‐based lie detection, to be contrasted with a piece by Dr Sean Spence presenting an opposite point of view ( Spence, 2008 ). This seemingly straightforward task presented two hurdles: having to respond to the popular as well as scientific view of what lie detection with fMRI is and present a wholly positive view of evolving experimental data. 相似文献

The demise of the USSR led to the collapse of its centrally organised retail system. With this collapse the supply of consumer goods dried up, especially in the remote parts of the former USSR. At the same time the advent of capitalism offered a new institutional framework for independent retail activities. In the Kyrgyz Republic, where the economic liberalisation followed strictly the Washington Consensus, a large number of small shops emerged in both urban and rural areas. This study analyses the reasons for this boom in retail start-ups as well as the constraints the mainly inexperienced merchants encounter. As will be shown, any success in retail activities depends greatly on the performance of other economic sectors. The main goal of starting a retail business is to minimize risks within the overall livelihood strategies of households in rural Kyrgyzstan. 相似文献
