Malawi is one of the poorest countries in Africa. There is widespread, though not universal, agreement about the shape of poverty in the country and the policy challenge this sets. Agriculture continues to be the most obvious means to stimulate broad-based rural growth and to provide levels of food security and income needed for the majority rural population. A longitudinal study over a decade during which radical policy and political changes occurred provides the data and basis for discussing the appropriate policy directions for reducing poverty.  相似文献

Drawing on interviews with 24 correctional practitioners who use risk assessment instruments daily, we examine barriers to the use and implementation of these instruments. Findings reveal that practitioners have confidence in the state of risk assessment generally, but are skeptical about risk assessment on the job due to limited resources. They also point to barriers that inhibit their effectiveness including recognition of population heterogeneity, predictive misspecification due to data lags and overemphasis on stable predictors, and lacking guidance on appropriate use of vast available data. Instruments for measuring risk serve purposes beyond those intended by the social scientists who developed measures. We conclude with lessons for increasing the utility and legitimacy of risk assessments and with a call for incorporating latent uses of assessments into design.  相似文献

One component of the increasing emphasis on management in the public sector is an emphasis on serving the “customer” of public sector agencies. Although it is difficult to argue that the clients of the public agencies should not be served courteously and efficiently, there are a number of questions about whether they should be thought of as customers in the same way as in the private sector. Some of those questions are empirical, related to difficulties in clearly identifying the customers of agencies. Other questions are normative, related to the proper definition of the role of the clients of public agencies and the definition of the public interest. These problems require serious rethinking of any simplistic adoption of a customer orientation in government.  相似文献

Barium and antimony levels from selected areas of the left and right hands of 269 nonshooters provide a database for interpretation of gunshot residue swab analysis results. The database represents a variety of activities of individuals sampled by collectors throughout the United States. Nonshooting exposure to barium and antimony can generally be distinguished from firearms-associated exposure by considering the relative levels of the elements, location on the hands, and condition of the swabs. Consistent definition of sampling procedures and accurate analytical results make this database applicable for interpretation of data generated by most gunshot residue swab examiners.  相似文献
