A review of the US ‘program evaluation standards’ (PES), undertaken in a series of workshops and meetings of networks of evaluators in Africa, resulted in modifications to those standards. The result was presented to a plenary session of the Inaugural Conference of the African Evaluation Association in September 1999, attended by over 300 evaluators from 35 countries. The AfrEA Conference decided that a systematic effort should be made to produce a list of African evaluation guidelines, similar to the PES, and that this checklist should be reviewed by national evaluation associations and networks in Africa and field tested in several countries. Ten national and regional networks and associations suggested modifications to the text and endorsed the final version of the guidelines. 相似文献

In light of use by airline unions of partial-strike tactics, such as concerted refusals to bid for overtime work and so-called
” CHAOS” tactics involving unannounced refusals to fly after passengers have been ticketed and are ready to board, the authors
examine whether the Railway Labor Act (RLA) should be interpreted to permit employers to discipline employees for engaging
in such tactics, or whether these are a protected form of economic pressure. Although in many respects bargaining duties and
economic weapons under the RLA are read consonant with precedents under the National Labor Relations Act (NLRA) (which governs
all industries other than rail and air transport), there are a few decisions suggesting that during the period when self-help
may be resorted to, employees can engage in partial strike activities as long as they violate no court order but are subject
to permanent replacement in limited circumstances. These decisions, the authors submit, fail to take account of Supreme Court
decsions since the 1930s that some economic pressures by unions, such as slowdowns and sitins, may not violate the labor laws
but nor are they protected by those laws so as to immunize partial strikers from employer discipline. These decisions are
not based on unique features of the NLRA. Rather, they give recognition to the background assumptions of Congress that employers
may act to protect their property interests as long as they do not run afoul of NLRA or RLA protections and that employees
who engage in partial-strike activities are subject to employer discipline even where not strictly necessary to maintain operations.
Moreover, these tactics skew the bargaining process by giving employees an essentially risk-free gambit to pressure their
economic position through planned disruption of carrier operations.

Ninna Nyberg–Sørensen Nicholas Van Hear & Poul Engberg–Pedersen 《International migration (Geneva, Switzerland)》2002,40(5):3-47
In September 2001, the Danish Ministry of Foreign Affairs commissioned a study of the present and potential links between migration and development. In January 2002, the new Danish Government announced a decision to enhance the links between its aid and refugee policies as part of the overall focus on poverty reduction. The present paper provides a state–of–the–art overview of current thinking and available evidence on the migration–development nexus, including the role of aid in migrant–producing areas. It offers evidence and conclusions around the following four critical issues: Poverty and migration People in developing countries require resources and connections to engage in international migration. There is no direct link between poverty, economic development, population growth, and social and political change on the one hand, and international migration on the other. Poverty reduction is not in itself a migration–reducing strategy. Conflicts, refugees, and migration Violent conflicts produce displaced persons, migrants, and refugees. People on the move may contribute both to conflict prevention and reconciliation, and to sustained conflicts. Most refugees do not have the resources to move beyond neighbouring areas, that is, they remain internally displaced or move across borders to first countries of asylum within their region. Aid to developing countries receiving large inflows of refugees is poverty–oriented to the extent that these are poor countries, but it is uncertain what effect such aid has in terms of reducing the number of people seeking asylum in developed countries. Furthermore, such aid may attract refugees from adjacent countries experiencing war or political turmoil. Migrants as a development resource International liberalization has gone far with respect to capital, goods and services, but not to labour. International political–economic regimes provide neither space nor initiatives for negotiations on labour mobility and the flow of remittances. There is a pressing need to reinforce the image of migrants as a development resource. Remittances are double the size of aid and target the poor at least as well; migrant diasporas are engaged in transnational practices with direct effects on aid and development; developed countries recognize their dependence on immigrant labour; and policies on development aid, humanitarian relief, migration, and refugee protection are internally inconsistent and occasionally contradictory. Aid and migration Aid policies face a critical challenge to balance a focus on poverty reduction with mitigating the conditions that produce refugees, while also interacting constructively with migrant diasporas and their transnational practices. The current emphasis on aid selectivity tends to allocate development aid to the well performing countries, and humanitarian assistance to the crisis countries and trouble spots. However, development aid is more effective than humanitarian assistance in preventing violent conflicts, promoting reconciliation and democratization, and encouraging poverty–reducing development investments by migrant diasporas. The paper is a synthesis of current knowledge of migration–development dynamics, including an assessment of the intended and unintended consequences of development and humanitarian policy interventions. We examine whether recent developments in the sphere of international migration provide evidence of a “crisis”, as well as the connections between migration, globalization, and the changing nature of conflicts. We summarize current thinking on the main issues at stake and examine available evidence on the relations between migration and development. Then the consequent challenges to the aid community, including the current debates about coherence and selectivity in aid and relief are discussed and, finally, we elaborate on the four conclusions of the overview. 相似文献

Service-learning programs are not free from challenges brought about by lack of financial support, lack of widespread commitment from professors, community agencies, and recipients of service, and lack of knowledge and insight in students directly involved in such programs. While service-learning initiatives and programs serve positive functions for organizations and individuals, rhetorical accolades for service learning can distort or omit the realities of program implementation and sustained delivery. This paper specifically explores the following challenges connected to service-learning programs: (1) pedagogical difficulties; (2) student limitations; (3) time constraints; and (4) community cooperation. 相似文献

Multiparameter evidence synthesis in epidemiology and medical decision-making: current approaches 总被引:1,自引:0,他引:1

Summary. Alongside the development of meta-analysis as a tool for summarizing research literature, there is renewed interest in broader forms of quantitative synthesis that are aimed at combining evidence from different study designs or evidence on multiple parameters. These have been proposed under various headings: the confidence profile method, cross-design synthesis, hierarchical models and generalized evidence synthesis. Models that are used in health technology assessment are also referred to as representing a synthesis of evidence in a mathematical structure. Here we review alternative approaches to statistical evidence synthesis, and their implications for epidemiology and medical decision-making. The methods include hierarchical models, models informed by evidence on different functions of several parameters and models incorporating both of these features. The need to check for consistency of evidence when using these powerful methods is emphasized. We develop a rationale for evidence synthesis that is based on Bayesian decision modelling and expected value of information theory, which stresses not only the need for a lack of bias in estimates of treatment effects but also a lack of bias in assessments of uncertainty. The increasing reliance of governmental bodies like the UK National Institute for Clinical Excellence on complex evidence synthesis in decision modelling is discussed. 相似文献
