The number of free or open access articles is increasing rapidly, and their retrieval with library indexes and OpenURL link resolvers has been a challenge. In June 2014, the SFX MISCELLANEOUS_FREE_EJOURNALS target contained more than 24,000 portfolios of all kinds. The SFX KnowledgeBase Advisory Board (KBAB) carried out an international survey to get an overview of the usage of this target by the SFX community and to precisely identify what could be done to improve it. The target is widely used among the community. However, many respondents complained about three major problems: (a) incorrect links, (b) full texts actually not free, and (c) incorrect or missing thresholds (years and volumes information). 相似文献

Studies reporting sociometric assessments based on nominations have been characterized by important methodological inconsistencies when conducted in the middle school context. The purpose of this study was to examine (1) the possibility of a response bias when participants are provided with a long roster sorted alphabetically, (2) the impact of including or not other‐sex peers in the voting population, and (3) the impact of including or not all the grademates in the voting population. Participants were 664 sixth graders from three middle schools. Peer nominations for sociometric items (i.e., like most and like least), as well as teacher ratings of antisocial behavior and records of academic performance, were collected. A sequence effect in peer nominations was found, suggesting that students whose names were listed higher on the rosters received more nominations than did students whose names were listed lower on the list. Moreover, results indicated that the nominations received from the other‐sex grademates and from the grademates outside the classroom improved the predictive validity of the sociometric measure. The implications of these results for the use of sociometric assessment in middle schools are discussed. 相似文献

This paper discusses a research agenda that arises from unanswered questions and unresolved issues considered in the World
Bank’s World Development Report 2006: Equity and Development. After formalizing the key concepts of equity; equality of opportunity; and efficiency, and proposing a definition for an
equitable development policy, the paper discusses the concept of inequality traps, around which the research agenda is structured.
Four broad groups of research questions are highlighted: those revolving around the measurement of inequality of opportunity
and the diagnostics for the existence of an inequality trap; those dealing with the causes of inequality traps; the quantification
of their efficiency costs; and those related to how institutions (including governments) evolve to overcome inequality traps.
Bourguignon and Ferreira are in the Development Economics Vice-Presidency, The World Bank. Michael Walton is at the John F.
Kennedy School of Government, Harvard University. Together, they led the team that produced the World Bank’s World Development Report 2006: Equity and Development. 相似文献

Irregular migrants and asylum seekers have died and continue to die attempting to cross the external borders of the EU without authorisation, seeking to enter the territories of its Member States. Yet, remarkably little is known about these ‘border deaths’. In 2015, the Human Costs of Border Control project published the Deaths at the Borders Database for the Southern EU, an open-source ‘evidence base’ of individualised information about people who have died border deaths between 1990 and 2013, sourced from the death management systems of Spain, Gibraltar, Italy, Malta and Greece. It is the first database on border deaths in the EU to be based on official sources as opposed to the news media. The project involved searching 563 state-run death registry archives and deductively selecting the death certificates of persons who died border deaths. This paper describes, in detail, the making of the Deaths at the Borders Database: from the systematic, multi-sited, quantitative data collection and qualitative case studies, to the construction and final results of the Database itself. 相似文献

How is it that catastrophes always seem predictable ex post but never ex ante? The paradox is recurrent. Our study of the warnings issued prior to one of the last major natural disasters in France – the tempest of December 27, 1999 – focuses on the organizational factors accounting for the surprise effect of the catastrophe, to try and understand why, though the phenomenon had been predicted and announced by the French weather bureau, the protagonists of Civil Defense said the magnitude of the event took them by surprise. A multi-level, qualitative analysis of the inter-organizational meteorological alert system shows that a combination of factors pertaining to structure, context and individuals transformed the warnings into routine messages. The case of the 1999 storm allows us to introduce a particular, ideal-type of risk, the treacherous risk, which, though clearly announced, was disregarded because seemingly so familiar. 相似文献

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations
of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated
on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and
Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared.
We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other
topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments,
in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.

The aim of this paper was to validate the Brazilian-Portuguese version of the Satisfaction With Life Scale (SWLS), presenting
evidence of its reliability and construct and criterion-related validity. A large Brazilian sample (2,180 participants), from
five different populations (undergraduate and high school students, general population, elementary school teachers, and physicians),
was considered. The results confirmed the single factorial structure and reliability (0.77 < Cronbach’s α < 0.88, mean α = 0.81)
of the SWLS. Supporting its criterion-related validity, the SWLS correlated positively with positive affect and negatively
with both negative affect and psychological distress across all five samples. The findings indicate that the Brazilian-Portuguese
version of the SWLS is a valid instrument to use with diverse Brazilian samples. 相似文献
