Visas and work permits: Possible global negotiating initiatives 总被引:1,自引:0,他引:1
We discuss global options for initiatives intended to ameliorate adverse impacts of visa and work permit systems used by national
governments around the world. We first describe and document some of their effects, noting the relative lack of other research
work on these issues. We then discuss proposals for a new and supplemental global visa structure which have been made as part
of the Mode 4 GATS negotiations in the WTO, suggesting that the GATS/WTO may be an imperfect institutional location for negotiating
on these matters. We then evaluate other approaches, including what realistically could be possible if a new body specifically
created for global negotiation in the area were to be used.

The use and non-use of policy appraisal tools in public policy making: an analysis of three European countries and the European Union 总被引:1,自引:0,他引:1

The increasing complexity of policy problems, coupled with the political desire to base new policies on the foundation of firm evidence, has accelerated the development of policy assessment tools. These range from complex computer models and cost benefit analysis through simple checklists and decision trees. In the last decade, many governments have established formal policy assessment systems to harness these tools in order to facilitate more evidence-based policy making. These tools are potentially widely available, but to what extent are they used by policy makers and what becomes of the evidence that they generate? This paper addresses these questions by studying the empirical patterns of tool use across 37 cases in three European countries and the European Commission. It uses a simple classification of tools into advanced, formal and simple types. It finds that even when tools are embedded in policy assessment systems, their use is differentiated and on the whole very limited, in particular when it comes to more advanced tools. It then explores these patterns from contrasting theoretical perspectives to shed light on why, when and how different policy assessment tools are used in the policy process. 相似文献

We investigate the role of Congress in the growth of federal public expenditure since 1930, building on the work of Kau and Rubin (Public Choice, 113:389–402, 2002). The model incorporates majority party strength and the extent of party control of Congress in addition to the median ideological position of elected representatives. We first provide estimates of the relative importance of the state of Congress and of trending supply and demand-side economic factors in the evolution of federal spending. The resulting models are then used to simulate the consequences of the radical and historically unprecedented shift to the right of Congress in 1994/95. 相似文献

Abstract: Governments around the world are spending huge sums of money implementing electronic government. Public‐private partnerships with information and communication technology firms have emerged as the vehicle of choice for implementing e‐government strategies. Concerns are raised about the capacity of governments to manage these complex, multi‐year, often multi‐partner relationships that involve considerable sharing of authority, responsibility, financial resources, information and risks. The management challenges manifest themselves in the core partnering tasks: establishing a management framework for partnering; finding the right partners and making the right partnering arrangement; the management of relationships with partners in a network setting; and the measurement of the performance of e‐government partnerships. The article reviews progress being made by governments in building capacity to deal with these core partnering tasks. It concludes that many new initiatives at the central agency and departmental/ministry level seem designed to centralize control of e‐government projects and wrap them in a complex web of bureaucratic structures and processes that are, for the most part, antithetical or, at best, indifferent to the creation of strong partnerships and the business valuethat e‐government public‐private partnerships promise. 相似文献

The food riots of 2007–2008 jolted authoritarian regimes and international agencies into action. The riots also began to crack neoliberal hegemony over the global food system. Food riots have often driven a politics of provisions, sometimes winning relief, sometimes merely bloody repression, depending on a particular country’s political economy. Such bargaining in the politics of provisions is made possible by existing networks – of solidarity among the common people and reciprocity between them and their rulers – that extend elements of ‘normal’ politics into crises. This paper explores how riotous extensions of such sociopolitical networks shaped food politics in early modern England and China, Famine Ireland, the ‘IMF (International Monetary Fund) austerity riots’ of the 1980s and 1990s, and the food riots of 2007–2008. 相似文献

Towards a Guide for Constructing and Disseminating Counternarratives to Reduce Support for Terrorism
Despite widespread recognition that the use of counternarratives is an important strategic component of countering violent extremism, to date, there are no comprehensive guidelines on how to develop and distribute counternarratives to effectively reduce support for terrorism. To redress this, we offer communication and psychology theory-based procedures for (1) analyzing terrorist narratives, (2) constructing counternarratives that challenge terrorist narratives, and (3) disseminating the counternarratives to overcome barriers to persuasion. Analysts and practitioners can use such guidelines in developing counternarratives to reduce support for violent extremism. 相似文献

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.
Key points
- Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
- Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
- These metrological principles also apply to individuation of unique objects in general.

This study focuses on the role of public capital stock in contributing to interstate differences in productive efficiency in manufacturing. Our motivation is to assess the role of public capital as a source of persistent regional variations in efficiency, and thus determine if public infrastructure policies might reasonably be expected to alter the competitive environment of a state's manufacturing sector. We use a stochastic frontier production function model, explicitly incorporating infrastructure capital, to examine the relative performance of the aggregate manufacturing sector across states and over time. We calculate an index of productive efficiency and estimate the determinants of statewide variations in it. These results show that variations in per capita infrastructure stocks significantly affect manufacturing efficiency. Considering the behavior of public capital as both a direct and an indirect input furthers our understanding of the role of infrastructure and its implications for regional economic development policies. 相似文献
