你为何如此忙碌?是忙那些能让你、团队和组织奔向愿景的重要事务吗?还是仅仅为忙碌而忙碌?在《要事第一》中,斯蒂芬·柯维、罗杰·梅里尔和丽贝卡·梅里尔写道:“人们期望我们忙碌,超负荷工作。在当今社会,‘忙’已逐渐成为身份的象征一如果忙,我们就是重要人物;如果不忙——我们简直羞于承认……通过忙碌,我们会得到安全感。忙,是种流行病,也让人上瘾。忙,更为我们没时间处理要事找了个好借口。” 相似文献

The post-war generation of baby boomers has witnessed major transformations in family life as well as being at the vanguard of them. A study undertaken in Paris and London in 2006 among 90 individuals born between 1945 and 1954 reveals, however, strong relationships with ageing parents and adult children. Family groups based on local or dispersed entourages, with regular contact and the exchange of support, are clearly identified. Other configurations include families where affective ties persist but contact between the baby boomers and their entourage is less frequent. Few baby boomers have replaced family members with friends or remain socially isolated. These results show that the rise of individualism associated with the baby boomers has not weakened inter-generational ties, although tensions exist between the demands of family solidarity and individual projects. 相似文献

Interpersonal relationships within and outside the family have been a central part of alcohol and substance use research. Many studies have focused on the role of parents and peers; fewer studies have focused on siblings. This article examines siblings’ roles in alcohol, tobacco, and other drug (ATOD) use patterns and trajectories in the context of familial and nonfamilial factors across time. First, intraclass correlations were used to examine the degree to which older siblings’ ATOD use was associated with younger siblings’ ATOD use. Second, hierarchical regression analyses were conducted to examine the degree to which individual, parent, sibling, and peer factors over time were associated with adolescents’ and young adults’ ATOD use. It should be noted that developmentally proximal predictors were utilized in these models and within-family replication was also examined. Results demonstrate strong associations between older and younger siblings’ ATOD use. Moreover, the developmentally proximal sibling variables were predictive of younger sibling ATOD use in the context of other variables across all substances. Study findings are discussed in terms of identifying promising and potentially malleable points of intervention for future investigators. 相似文献

We present an analysis and discussion of the tanda, a multiperson pooled credit and savings scheme (a rotating credit association or RCA), as described by two informants from Mexican immigrant communities in California. In the tanda, participants contribute regularly to a common fund which is distributed to participants on a rotating basis. We analyze the tanda at multiple levels (as a mathematical, cultural, and distributed practice) and identify points of intersection and conflict. Contrary to many formal or school-based conceptions of mathematics, mathematical work in the context of the tanda is in service of, and intimately tied up with, cultural goals and values. Likewise, cultural means and mathematics are employed to personal ends. We argue that the tanda should be of enduring interest, particularly among educators interested in bringing more authentic, culturally-relevant mathematics into classroom settings, because it so clearly illustrates how mathematical and cultural processes can interact in the context of personal goals, and provides a potentially valuable template for engaging, consequential, and successful mathematics. 相似文献

The paper reports secondary analysis of data from the 2010 British Gambling Prevalence Survey, a household survey of a representative sample of the population aged 16 years and over (N = 7756). Responses to questions about frequency of gambling and average monthly spend on each of 15 forms of gambling, and responses to two different problem gambling screens (DSM-IV and PGSI), were used to derive estimates, for each form of gambling separately, of the percentage of (1) all days play (two estimates), and (2) all spend (four estimates), attributable to problem gamblers. Although these estimates must be treated as approximations only, they demonstrate that problem gamblers make a far greater contribution to total gambling attendances and losses than problem gambling prevalence figures would suggest. There are certain forms of British gambling to which problem gamblers may be contributing as much as 20–30% of all days play and spend, and moderate risk gamblers a possible further 10–20%. 相似文献

ResumenEl presente estudio supone una aplicación tentativa de la técnica del autoinforme a la codificación y decodificación de las manifestaciones corporales y expresivas asociadas al comportamiento emocional. El interés en el uso de dicha técnica radica, no tanto en la posibilidad de determinar los cambios reales asociados a la emoción, como de conocer el modo en que los sujetos recuerdan y categorizan su experiencia emocional. 相似文献

Many prior efforts have examined the personal characteristics of workers or the structural features of an organization that impact job satisfaction. By contrast, we examine organizational culture in the context of "high-performance work systems." We analyze the organizational culture of the United States Postal System, as it is presented in key organizational documents and perceived by workers. It is argued that a viable theory of job satisfaction in the modern workplace must treat worker perceptions, which spring from an organizational culture that is both prescribed and lived. 相似文献

In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios. 相似文献

Scour (localized erosion by water) is an important risk to bridges, and hence many infrastructure networks, around the world. In Britain, scour has caused the failure of railway bridges crossing rivers in more than 50 flood events. These events have been investigated in detail, providing a data set with which we develop and test a model to quantify scour risk. The risk analysis is formulated in terms of a generic, transferrable infrastructure network risk model. For some bridge failures, the severity of the causative flood was recorded or can be reconstructed. These data are combined with the background failure rate, and records of bridges that have not failed, to construct fragility curves that quantify the failure probability conditional on the severity of a flood event. The fragility curves generated are to some extent sensitive to the way in which these data are incorporated into the statistical analysis. The new fragility analysis is tested using flood events simulated from a spatial joint probability model for extreme river flows for all river gauging sites in Britain. The combined models appear robust in comparison with historical observations of the expected number of bridge failures in a flood event. The analysis is used to estimate the probability of single or multiple bridge failures in Britain's rail network. Combined with a model for passenger journey disruption in the event of bridge failure, we calculate a system‐wide estimate for the risk of scour failures in terms of passenger journey disruptions and associated economic costs. 相似文献
