Governments throughout the world are requiring greater use of economic analysis as a way of informing policy decisions. This paper provides a comprehensive analysis of the use of impact assessment in the European Union, using US assessments as a benchmark. We find that recent EU impact assessments include more economic information than they did in the past, although important items are still missing. We also provide evidence that the quality of EU impact assessment increases with the expected cost of a proposal. Furthermore, we find that the quality of EU assessments that report high total costs is similar to that of US assessments.  相似文献

In recent years, interest has soared in the development potential of well‐designed cash transfer programs. One particular application is the use of transfers by resource‐rich countries (as recently initiated by Iran) to distribute rents across their populations. An emerging body of research suggests that the development impact of such programs tends to be positive and that, especially when received by poor individuals or households, they can unlock constraints on economic activities, allowing a further increase in income. This paper considers the use of biometric technology to underpin transfer programs and how new technology is opening up possibilities for effective transfer programs that, up to now, have only been a theoretical option in the institutional conditions that prevail in many developing countries. Once implemented, biometric identification systems can be used to support a wide range of other development initiatives including banking, voting, health care, and general identification systems. The paper reviews some of the programs using these technologies and how it is enabling poor countries to leapfrog rich ones in the area of identity, much as the cellphone revolution did in the area of communications.  相似文献

This paper reviews the literature on poverty dynamics in the U.S. It surveys the most prevalent data, theories, and methods used to answer three key questions: How likely are people to enter, exit, and reenter poverty? How long do people remain in poverty? And what events are associated with entering and exiting poverty? The paper then analyzes the combined findings of the literature, discussing overarching patterns of poverty dynamics, differences among demographic groups, and how poverty probabilities, duration, and events have changed over time. We conclude with a discussion of the policy implications of these findings and avenues for future research. © 2008 by the Association for Public Policy Analysis and Management.  相似文献

Abstract

This study explored some of the factors involved in parking violations, using as a framework the model of tax evasion developed by Weigel, et al. (1987). Two groups of parkers were observed, offenders (N = 121) and non-offenders (N =128). Two questionnaires were employed. An initial questionnaire was used at the time of the observed behaviour to ascertain situation-specific factors followed by the main questionnaire which measured attitudes, moral beliefs, social norms and controls, perceived risk and severity of punishment and personal characteristics. Results revealed that the Weigel et al. model was a good predictor of parking violation with both economic and psychological factors being important determinants. There was also a significant correlation between observed and self-reported behaviour. Implications for understanding rule-breaking behaviour in general are also discussed.  相似文献

With continual advances in Internet capability the child pornography market is experiencing a boom in demand and supply. Attempts to reduce the market challenge legislators, law enforcement agencies, practitioners and researchers alike – due in large part to the decentralised and global nature of the Internet. Much research has focused on frequent users of child pornography and whether such behaviour is interrelated with child sexual assaults. This article instead draws attention to onset, the first deliberate viewing of child pornography. It presents the results of a three-month study of a global Peer-to-Peer network, isoHunt. Analysis of the site’s Top 300 search terms indicated that child pornography is consistently shared. Risk factors for onset are discussed, including the potential normalisation of child pornography among Internet subcultures. Strategies are discussed to encourage subcultures to inhibit child pornography use and to increase understanding of the harms associated with such material. Implications for legal systems, policy and research are explored.  相似文献

Nanotechnologies are reshaping the boundaries between industries, combining two aspects of innovation—both enhancing competences based on cumulative knowledge and experience and destroying competences by forcing the renewal of the firm’s knowledge base. To analyze how worldwide R&D leaders adapt to this new technology, we conduct an econometric analysis of about 3,000 subsidiaries of the largest R&D spenders. We find that large groups are creating medium size subsidiary companies to explore nanotechnologies. Knowledge circulates mostly amongst subsidiaries within the same group and scientific clusters do not affect their involvement in nanotechnologies. Nanotechnologies remain marginal within these subsidiaries’ knowledge bases and are distributed within corporate groups, stimulating recombination between nanotechnology and other technologies.  相似文献

A calibration test is described for monitoring the operation of equipment used to develop latent fingerprints on thermal paper by the application of either controlled or uncontrolled heat. A working solution of a water/glycerol emulsion and butylene glycol is applied to thermal paper by means of either a vinyl stamp and pad, or a marker pen. Varying the amount of butylene glycol enables the thermal paper to change color at different temperatures between approximately 40 and 60°C, which is below the normal color change temperature of the paper. The described test may be used to verify the correct operation, at different temperatures, of a controlled heat source during and after fingerprint development (such as the Hot Print System) or to monitor the paper temperature with an uncontrolled heat source (such as a warm air blower), thereby avoiding unintentional coloring of the entire paper surface.  相似文献

Abstract: One hundred Korean adults (50 men, 50 women) were scanned in the upright position using a cone‐beam CT (CBCT) scanner. The soft tissue (ST) thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral landmark sites, and the means and standard deviations were obtained for male and female subjects. While 18 of 31 landmarks showed sex differences, the majority showed higher values for male subjects with the exception of a few landmark sites corresponding to the zygoma area, which showed smaller values in men than in women. The mandibular area showed greater differences between the right and left sides. Overall, the ST thickness measurements obtained in this study can be used as a database for the forensic craniofacial reconstruction of Korean adult faces.  相似文献

This note considers the Supreme Court decisions in Manchester CC v Pinnock and Hounslow LBC v Powell. It is argued that there are a number of remaining outstanding questions around proportionality, including: deference; section 89, Housing Act 1980; procedural issues; ‘publicness’; and the future landscape.  相似文献
