Sociolinguistic research has demonstrated that gossip is a co‐constructed phenomenon, which allows participants to establish solidarity and build alignments with each other, while evaluating an absent party. Gossip can also serve important social functions, such as helping to establish and reconfirm group norms and values. The present study provides a detailed analysis of an extended gossip episode that occurred within an institutional context: a study group interaction at a U.S. university. Our analysis shows how, in gossip, constructed dialogue both prompts and legitimizes pejorative evaluations towards an absent third party, and is actually the pivot around which group members negotiate values and norms in the process of arriving at a shared moral stance. Our analysis also demonstrates that alignment in gossip interactions is tenuous and must be continuously renewed. 相似文献

This article deals with a stochastic optimal control problem for a class of buffered multi-parts flow-shops manufacturing system. The involved machines are subject to random breakdowns and repairs. The flow-shop under consideration is not completely flexible and hence requires setup time and cost in order to switch the production from a part type to another, this changeover is carried on the whole line. Our objective is to find the production plan and the sequence of setups that minimise the cost function, which penalises inventories/backlogs and setups. A continuous dynamic programming formulation of the problem is presented. Then, a numerical scheme is adopted to solve the obtained optimality conditions equations for a two buffered serial machines two parts case. A complete heuristic policy, based on the numerical observations which describe the optimal policies in system states, is developed. It will be shown that the obtained policy is a combination of a KANBAN/CONWIP and a modified hedging corridor policy. Moreover, based on our observations and existent research studies extension to cover more complex flow-shops is henceforth possible. The robustness of such a policy is illustrated through sensitivity analysis. 相似文献

Video recording provides an objective record of the content of medical interactions. However, there is concern that cameras
may be reactive measurement devices that alter what normally transpires during interactions. This study addressed potential
reactivity of cameras in medical interactions. Interactions between 45 patients and 14 medical oncologists were video recorded
and coded for camera-related behaviors. Eleven of 45 patients performed none of the behaviors. Among the other patients, camera-related
behaviors were infrequent and, on average, constituted about 0.1% (one-tenth of one percent) of total interaction time. Behaviors
occurred most often in very early stages of interactions, and when physicians were absent from the room. Seven physicians
showed camera-related behaviors, comprising less than 0.1% of the time they were in the interaction. Results suggest video
recording can provide nonreactive means of studying medical interactions.

Social networks are complex systems composed of interdependent organizations and people with diverse network structures. Understanding network dynamics, such as exchange commitment, requires a methodological toolkit that does not assume away complexity. In this study, we extend a technique for analyzing longitudinal, multilayer network data called network alignment. We introduce a novel metric – intersect proportions – for analyzing similarity between divergent graphs. We demonstrate the application of network alignment and intersect proportions to the context of investor commitment to startups and entrepreneurs. Using this technique, we are able to disentangle exchange commitment across complex networks. 相似文献

In the context of heightened interest in social business and a renewed focus on the performance of international aid, this article explores the role and place of aid in addressing poverty in relation to the rapidly growing social business regime. Research on the subject is surprisingly limited. The article begins by operationalizing the key concepts, and developing a conceptual framework by exploring the possible nexus points between aid alignment and social business. It then addresses a number of key dimensions of aid; notably, a comparative account of possible aid investment in social business vis‐à‐vis conventional projects and private sector enterprises; an examination of the realities on the ground of the social business projects; and policy implications of the study together with some recommendations. 相似文献

为了向分布式实时嵌入式系统(DRES)的运行过程提供可信保障服务,方便上层应用程序的开发,提出了一种针对DRES的可信构件服务模型QUOCCM。该模型将系统功能实现与性能确保分离开,把应用程序的性能确保模块抽象成通用的服务确保构件,为运行于动态环境下的应用程序提供自适应的可信保障服务。该文以一个模拟实现的飞行控制系统验证了QUOCCM模型的可行性和灵活性。 相似文献
