This article reports results of a field experiment in which two hundred e-mails were sent to authors of recent articles in economics that had promised to send the interested reader supplementary material, such as alternative econometric specifications, “upon request.” The e-mails were sent either by a researcher affiliated at Columbia University, New York or the University of Warsaw, Poland; furthermore, the authors' position (assistant professor) was specified in half the e-mails only. Overall, 64% of the approached authors responded to our message, of which two thirds (44% of the entire sample) delivered the requested materials. The frequency and speed of responding and delivering were very weakly affected by the position and affiliation of the sender. Gender or affiliation of the author, number of citations or journal impact factor or the type of object in question seemed to make no difference. However, authors of published articles were much more likely to share than authors of working papers. 相似文献

The recent occurrence of severe major accidents has brought to light flaws and limitations of hazard identification (HAZID) processes performed for safety reports, as in the accidents at Toulouse (France) and Buncefield (UK), where the accident scenarios that occurred were not captured by HAZID techniques. This study focuses on this type of atypical accident scenario deviating from normal expectations. The main purpose is to analyze the examples of atypical accidents mentioned and to attempt to identify them through the application of a well-known methodology such as the bow-tie analysis. To these aims, the concept of atypical event is accurately defined. Early warnings, causes, consequences, and occurrence mechanisms of the specific events are widely studied and general failures of risk assessment, management, and governance isolated. These activities contribute to outline a set of targeted recommendations, addressing transversal common deficiencies and also demonstrating how a better management of knowledge from the study of past events can support future risk assessment processes in the identification of atypical accident scenarios. Thus, a new methodology is not suggested; rather, a specific approach coordinating a more effective use of experience and available information is described, to suggest that lessons to be learned from past accidents can be effectively translated into actions of prevention. 相似文献

Composite materials is an industry where technology selection has major consequences as there is not a standard manufacturing process, nor are there standardised materials with defined or proscribed properties for companies to select as multiple solutions are technically viable. This research aims to identify key factors for manufacturing technology selection in the UK composite materials supply chain. Literature review and managers’ opinions were used to identify 18 factors affecting manufacturing technology selection. This was followed by a survey comprising the multi-tier supply chain of the composite materials industry. The results of the survey show ‘on time deliveries/service level to customers’, ‘improve quality’ and ‘reduce cycle time’ received the highest average ratings. In this study a correlation analysis was performed to identify the underlying dependencies between the factors investigated. The identification and use of underlying dependencies rather than highest average provided a more comprehensive picture of the factors that affect technology selection in the composite materials industry. For this study, experts in composite materials were asked to comment on the findings of the survey and their value to the industry. The results presented may assist companies in the composite materials industry with technology selection decision-making processes. 相似文献

Isuani EA. The Argentine welfare state: enduring and resisting changeInt J Soc Welfare 2010: 19: 104–114 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. It is widely accepted that during the 1990s, the Argentine state experienced a general retrenchment. This article shows that, though this may have been true in the economic realm, this retrenchment did not take place in the diverse arenas of social policy. While privatisations and labour market flexibility dismantled the foundations of Keynesianism, the components of the welfare state experienced substantial growth. At the same time, the changes experienced by the welfare state in the past quarter century have not included a transformation of its basic principles, despite the profound changes experienced by Argentine society during this period. 相似文献

I evaluate the regional and local economic impact of the University of Cardiff, dividing its effects into two major sides:
expenditure impacts and knowledge impacts. I review the major tools and methodologies available in the literature to assess
the two sides. The expenditure impact in the financial year 2000–2001 is measured through a Keynesian multiplier model developed
by the Centre for Advanced Studies in Social Sciences, Cardiff University, in order to compare that same impact in the 1994–1995
financial year. The university’s knowledge impact is assessed through two main variables: (1) employment and destination of
graduates, or people impact, and (2) kind of knowledge produced. Cardiff University’s graduates enjoy full-employment, and
according to our conceptual framework, Cardiff’s higher education system is classified as “nonactive” positional competition
and “social” knowledge production.

With the growing interest worldwide in making communities more age-friendly, it is becoming increasingly important to understand the factors that help or hinder communities in attaining this goal. In this article, we focus on rural and remote communities and present perspectives of 42 experts in the areas of aging, rural and remote issues, and policy who participated in a consensus conference on age-friendly rural and remote communities. Discussions highlighted that strengths in rural and remote communities, such as easy access to local leaders and existing partnerships, can help to further age-friendly goals; however, addressing major challenges, such as lack of infrastructure and limited availability of social and health services, requires regional or national government buy-in and funding opportunities. Age-friendly work in rural and remote communities is, therefore, ideally embedded in larger age-friendly initiatives and supported by regional or national policies, programs, and funding sources. 相似文献

Many SMEs in the Italian fashion industry do not find a fit between strategy and structure able to open them to growth and
new opportunities in emerging international markets. Through an in depth analysis of a successful business case, a contribution
is made to the study of strategy–structure fit in the Italian fashion industry, with particular reference to the international
growth phase. The case confirms the causal link between strategy and structure. However, the development route in the fashion
sector does not follow the historical model analysed by Chandler: Uppsala’s model of incremental and cognitive internationalisation
appears to be the more appropriate reference for Italian “industrial networks”, characterised by creative dynamics that are
constantly evolving, and strong needs for structural flexibility and strategic change. 相似文献

A framework for simplified implementation of the collective model of labor supply decisions is presented in the context of
fiscal reforms in the UK. Through its collective form the model accounts for the well known problem of distribution between
wallet and purse, a broadly debated issue which has so far been impossible to model due to the limitations of the unitary
model of household behavior. A calibrated data set is used to model the effects of introducing two forms of the Working Families’
Tax Credit. We also summarize results of estimations and calibrations obtained using the same methodology on data from five
other European countries. The results underline the importance of taking account of the intrahousehold decision process and
suggest that who receives government transfers does matter from the point of view of labor supply and welfare of household
members. They also highlight the need for more research into models of household behavior.
