The article responds to a critical discussion of sociological world society research and our article “What makes globalization possible?” (KZfSS 63/2011) by Markus Holzinger in the present issue of this journal. We repeat the central point made in our earlier article: that world society theories should be seen and used as a heuristic device to develop a historical sociology of globalization, rather than transferring obsolete controversies within sociological theory to yet another research field. To make this point, we (2) recapitulate our article, showing where and how we see it as being misrepresented in Holzinger’s article. Against this background, we (3) discuss a typical research interest of world society theories—the relationship between global structures (expectations, institutions) and the local appropriation of (or dissociation from) them—using the example of the decoupling-thesis by the Stanford School. 相似文献

Recent literature has suggested that population aging may shape energy demand and related emissions. Recent scholarship also
suggests that emissions play a role in contemporary climate change and, as such, understanding the effect of population compositional
change has considerable environmental policy importance. The purpose of this paper is to empirically investigate the macro-level
relationship between population aging and emissions of sulfur dioxide. We extend a standard macroeconomic estimation function
by including the age composition of the population. In doing so, we separate, for the first time in the literature on aging
and the environment, the life-cycle dimension of the age structure from its cohort dimension. We utilize data representing
a balanced panel of 25 OECD countries during the period from 1970 to 2000. Consistent with our expectations, we find that
societies with a low proportion of young and a high proportion of senior citizens emit more sulfur dioxide. At the same time,
our results suggest that a high proportion of individuals born before 1960 is positively correlated to national sulfur dioxide
emissions. Our study contributes to understanding of past emission patterns in OECD countries and the findings may allow for
improvements in future emission projections. 相似文献

The sustainability challenges society faces call for firms to manage their use of natural resources wisely. Prior work on firm responses to sustainability challenges has largely focused on explaining and enhancing economic rather than environmental performance. We build on recent developments to extend resource dependence theory to include natural resources and seek to explain how business- and environment-related firm activities influence the use of natural resources. Using a configurational approach, we develop a conceptual model that explains the return on natural resources of firms based on four distinct sets of business- and environment-related comparative advantages. An illustrative application to the car-manufacturing sector demonstrates the practical applicability of our model and provides first insights into configurations we are likely to observe in practice. Our model and its application show that economic success is neither necessary nor sufficient to enhance a firm's return on natural resources. 相似文献

Industry trends such as product customization, radical innovation, and local production accelerate the adoption of mixed-model assembly lines (MMALs) that can cope with a widening gap between model processing times and true build to order capabilitiy. The existing high work content deviations on such assembly lines stress production planning, especially the assembly line sequencing. Most manufacturers set the launching rate for all assembly line products to a fixed launching rate resulting in rising utility work and idle time when system load increases. We present an “ideal” variable rate launching (VRL) case resulting in minimal computation and achieving 100% productivity (full elimination of idle time and utility work) for balanced assembly times and homogeneous station lengths. Managers should foster the ideal circumstances where operators need not wait for a preceding task to be completed and product sequence restrictions are eliminated, thus enabling unmatched production flexibility. Furthermore, we present a mixed-integer model to analyze both closed and open workstations on an MMAL for fixed rate launching and VRL. This model incorporates costs not only for labor inefficiencies but also for extending the line length. We present a heuristic solution method when process times and station lengths are heterogeneous and demonstrate that the variable takt dominates the fixed takt. In a numerical, industrial benchmark study, we illustrate that a VRL strategy with open stations has significantly lower labor costs as well as a substantially reduced total line length and thus lower throughput time. 相似文献

External validity is an important parameter that needs to be considered for decision making in health research, but no widely accepted measurement tool for the assessment of external validity of randomized controlled trials (RCTs) exists. One of the most limiting factors for creating such a tool is probably the substantial heterogeneity and lack of consensus in this field. The objective of this study was to reach consensus on a definition of external validity and on criteria to assess the external validity of RCTs included in systematic reviews. A three-round online Delphi study was conducted. The development of the Delphi survey was based on findings from a previous systematic review. Potential panelists were identified through a comprehensive web search. Consensus was reached when at least 67% of the panelists agreed to a proposal. Eighty-four panelists from different countries and various disciplines participated in at least one round of this study. Consensus was reached on the definition of external validity (“External validity is the extent to which results of trials provide an acceptable basis for generalization to other circumstances such as variations in populations, settings, interventions, outcomes, or other relevant contextual factors”), and on 14 criteria to assess the external validity of RCTs in systematic reviews. The results of this Delphi study provide a consensus-based reference standard for future tool development. Future research should focus on adapting, pilot testing, and validating these criteria to develop measurement tools for the assessment of external validity. 相似文献

Festivals are an important sub‐field within event studies which, until recently, have not been studied as separate experiences. A systematic review of the emerging literature on festivals reveals several key characteristics. While festivals are diverse in nature and geographical location, scholarly interest focuses on five main themes: the motivations for organizing, funding and attending festivals; the experiences of festival attendees; the relationship between festivals and their local environments; the economic and sociocultural impacts of festivals; and the management of festivals. Despite growing interest in festivals as research sites, little attention has been afforded to investigating festival processes. In particular, considerations of how festivals are established, and which individuals are involved in their initiation and regular staging, offer opportunities for research. This paper highlights the significant role festivals play within their local communities, including their facilitation of social cohesion and regional identity. Our study reveals that the literature rarely discusses the development of festivals over time and the wider networks in which festivals are embedded. This critical review of festival research identifies various research gaps and directions for future research to develop theory and practical understanding of festivals. 相似文献

Sensitive responding to eye cues plays a key role in human social interactions. Pupil size provides subtle cues regarding a social interaction partner's arousal states. The current study assessed infants’ sensitivity to and preference for differences in pupil size. Specifically, we examined White 14-month-old infants’ pupillary responses when viewing own-race and other-race (Asian) eyes with dilating, constricting, and static medium-sized pupils. Our results show that, independent of race, infants’ pupils dilated more when viewing eyes with dynamically changing (dilating and constricting) pupils than when viewing eyes with non-changing, static, and medium-sized pupils. We also measured infants’ looking preferences, showing that, independent of race, infants preferentially attended to eyes with dilated pupils. Moreover, our results show that infants orient more quickly to pupillary changes in own-race eyes than in other-race eyes. These findings demonstrate that infants detect, but do not mimic, changes in pupil size in others and show a preference for eyes with dilated pupils. 相似文献

ABSTRACTWhile the fact that the implementation of migration policies fails to perfectly manage migration is well known, the actual dynamics of policy implementation have received little attention to date. A serious engagement with this phenomenon requires a move beyond policy texts and political intentions, and towards a ‘migration regime’ perspective that pays attention to the inherent contradictions, conflicts of interest and competing logics within migration control practices. This collection posits a multi-actor perspective that includes state agents, migrants and non-state actors alike and proposes three key factors that require a closer examination: competing institutional logics, discretionary practices and migrants’ agency. Based on original empirical research, the contributions of this collection ‘zoom in’ on specific asymmetrical negotiations over the right to enter or remain in Europe, and focus on the institutional logics and interplay between the different actors involved. 相似文献
