Much work is carried out in short, interrupted segments. This phenomenon, which we label task juggling, has been overlooked by economists. We study the work schedules of some judges in Italy documenting that they do juggle tasks and that juggling causally lowers their productivity substantially. To measure the size of this effect, we show that although all these judges receive the same workload, those who juggle more trials at once instead of working sequentially on few of them at each unit of time, take longer to complete their portfolios of cases. Task juggling seems to have no adverse effect on the quality of the judges' decisions, as measured by the percent of decisions appealed. To identify these causal effects we estimate models with judge fixed effects and we exploit the lottery assigning cases to judges. We discuss whether task juggling can be viewed as inefficient, and provide a back‐of‐the‐envelope calculation of the social cost of longer trials due to task juggling. 相似文献

Despite the numerous benefits of physical activity, older adults continue to be more sedentary than their younger counterparts, and sedentary behavior is more prevalent among older racial and ethnic minorities than among Whites. This study used the nominal group technique (NGT) to examine participants' perceptions of what neighborhood environmental changes would encourage greater physical activity for older African American and Hispanic women. Participants age 50-75 years were recruited from 2 urban community health clinics. Nine NGT sessions (45 participants) were conducted. The women were asked what changes in their neighborhood environment would encourage them to become more physically active. Responses to the research question were tabulated, and qualitative analysis was used to identify themes and categories. Major categories were physical environment changes, safety, and activities/social support. Although the physical environment received the greatest number of points, concerns for personal safety cut across categories. Participants indicated the need for more facilities in which to be active. 相似文献

Wind power is becoming an increasingly important part of the global energy portfolio, and there is growing interest in developing offshore wind farms in the United States to better utilize this resource. Wind farms have certain environmental benefits, notably near‐zero emissions of greenhouse gases, particulates, and other contaminants of concern. However, there are significant challenges ahead in achieving large‐scale integration of wind power in the United States, particularly offshore wind. Environmental impacts from wind farms are a concern, and these are subject to a number of on‐going studies focused on risks to the environment. However, once a wind farm is built, the farm itself will face a number of risks from a variety of hazards, and managing these risks is critical to the ultimate achievement of long‐term reductions in pollutant emissions from clean energy sources such as wind. No integrated framework currently exists for assessing risks to offshore wind farms in the United States, which poses a challenge for wind farm risk management. In this “Perspective”, we provide an overview of the risks faced by an offshore wind farm, argue that an integrated framework is needed, and give a preliminary starting point for such a framework to illustrate what it might look like. This is not a final framework; substantial work remains. Our intention here is to highlight the research need in this area in the hope of spurring additional research about the risks to wind farms to complement the substantial amount of on‐going research on the risks from wind farms. 相似文献

Analysis of quality-of-life adjusted failure time data in the presence of competing, possibly informative, censoring mechanisms 总被引:1,自引:1,他引:0
We derive estimators of the mean of a function of a quality-of-life adjusted failure time, in the presence of competing right
censoring mechanisms. Our approach allows for the possibility that some or all of the competing censoring mechanisms are associated
with the endpoint, even after adjustment for recorded prognostic factors, with the degree of residual association possibly
different for distinct censoring processes. Our methods generalize from a single to many censoring processes and from ignorable
to non-ignorable censoring processes. 相似文献

In two social perception experiments, we explore the relationship between the social meaning and the semantic/pragmatic properties of the intensifier totally in American English. In Experiment 1, we show that totally is perceived as a more salient index of social identity categories – measured in terms of Age, Solidarity and Status attributes – when it targets a scalar dimension grounded in the speaker's attitude, as opposed to when it occurs in contexts where the scale is provided by the subsequent predicate. In Experiment 2, we show that the social indexicality of totally is even more salient in contexts in which the intensifier, by virtue of its pragmatic contribution, invites a stance of heightened proximity and convergence between the interlocutors. These results point to a principled connection between the semantic, pragmatic and personality‐based social meanings of totally, providing new insights into the dynamics whereby different layers of meaning conspire to determine what an expression ‘says’ when deployed in interaction. 相似文献

We submit that offshoring research focused mostly about an empirical phenomenon and extending our understanding about it, rather than expanding our understanding of the underlying theory as illuminated by empirical evidence. To theoretically frame the implications of offshoring strategy and practice for organizational design, this paper centers on the interplay between coordination and geographical distance. Distance strains the traditional approaches to coordination – i.e. decomposability and communication – as it impacts on knowledge boundaries created by the decomposition scheme. This increases the inherent complexity of the international division and coordination of innovative labor and knowledge and calls for new organizational practices. 相似文献

This paper investigates the relationships of the choice of philanthropic strategy with board capital (diversity and networks), board activities (board processes, internal board committees, and board effectiveness), and CEO leadership. Using a sample of 110 Italian foundations, the research shows that board processes have the strongest positive association with an evolved strategic approach to philanthropic institutional grant-giving, while board diversity and strong CEO leadership are associated with the strategic approach only under certain conditions. In particular, good governance processes (e.g., training the board, self-evaluation of trustees, setting the stage for effective board and committee meetings, implementing control software, and steering meetings to improve the board’s analysis) are positively associated with evolved strategic approaches to philanthropy (e.g., signaling other funders for the best grantees, improving the performance of grant recipients, and advancing selected social fields’ state of knowledge and practice). 相似文献

This article examines the representations of men and masculinities in contemporary crime narratives featuring a female protagonist. These “chick dick” stories (which adapt elements from the hardboiled detective novel, film noir, chick lit, and chick flicks) repeatedly engage with the gendered power dynamics made visible and problematic through the intersection of “chick” and crime genres, most particularly the sexualization of violence. In these narratives, popular masculinities operate as deployable concepts to dramatize contemporary gender relations. By tapping into the popular sentiment of a “crisis in masculinity,” chick dick texts also mobilize a rhetoric of unrepresentable male victimization and individual male pathologies. This strategy highlights the spaces and places in which masculinities are made vulnerable at the same time as it offers simplistic and individualized explanations for the systemic sexualized violence that dominate these narratives. 相似文献
