Suppose that a technical system is subject to shocks, e.g. peaks of voltages from a sequence of identically independent voltages having a lower limit value v>0. We propose a new definition for the mean residual life of the records of the sequence and study its various properties. 相似文献

Bureaucratic discretion is a fundamental feature of social provision,one that presents enduring difficulties for management. In general,management reform has taken two, divergent paths. One, utilizingthe familiar public bureaucratic model, seeks to control discretionthrough hierarchical command structures and standardization.The other, utilizing decentralization and privatization, regulatesand relocates discretion, using incentive structures associatedwith market or quasi-market institutions. However, it may bethat discretion will prove to be as problematic for the newpublic management (NPM) as it was for the old. This articleoffers a critical political history of management reformism,reviewing efforts to reorganize the public welfare provisionby applying new public management models to old public bureaucracyproblems. It considers the dynamics of bureaucratic discretionand reform not only as a problem of public management but aspart of the contested politics of social policymaking. 相似文献

This article examines second-generation Asian Americans' explanations of the significant influences on their own religious identities. Data include interviews (N = 73) with college-aged Asian Americans from different religious traditions and ethnic backgrounds. Respondents viewed families as the most significant influence on current religiosity. Mothers and fathers were mentioned most often, followed by extended kin, siblings, and relatives, who acted as what we call "reinforcers,""substitutes," or "contrasts" to the roles that parents played in religious socialization. These roles occurred along two religious configurations within families: heterogeneous or homogeneous degrees of religious commitment and religious affiliation. Directions for future research and contributions to the religious transmission literature follow. 相似文献

Stancetaking and the joint construction of zine producer identities in a research interview 下载免费PDF全文

This article examines the construction of zine producer identities (self and other) during a research interview. Zines are self‐published texts that circulate in mainly underground communities. In this study, I draw on dialogic understandings of the notion of ‘stance’ to show how a zine producer accomplishes a situated identity performance in the interview that also functions as an interdiscursive move in a larger conversation about the role Do‐It‐Yourself (DIY) ethics should play in zine communities. Specifically, I show how this speaker displays stances in relation to recognizable social types within zine communities but also the canonical stances associated with these social types. I unpack the features that work in support of this stancetaking, including discourse markers, constructed dialogue, referring terms, and prosodic cues. The analysis also foregrounds how the interviewer's turns contributed to these emergent stance displays, which furthers our understanding of the dynamic social context of the research interview. 相似文献

The article explores the dynamics of Indian fertility at the district level using a child‐woman index developed from the four Indian censuses, 1961 to 1991. It employs statistical and geostatistical techniques to assess fertility change across districts and periods. Fertility decline is evident in every region, but sizable regional differentials exist. A cluster analysis of fertility profiles indicates that a clear spatial pattern of fertility in India has emerged and the pattern intensified because of the process of fertility decline. 相似文献

We propose a new biclustering method for binary data matrices using the maximum penalized Bernoulli likelihood estimation. Our method applies a multi-layer model defined on the logits of the success probabilities, where each layer represents a simple bicluster structure and the combination of multiple layers is able to reveal complicated, multiple biclusters. The method allows for non-pure biclusters, and can simultaneously identify the 1-prevalent blocks and 0-prevalent blocks. A computationally efficient algorithm is developed and guidelines are provided for specifying the tuning parameters, including initial values of model parameters, the number of layers, and the penalty parameters. Missing-data imputation can be handled in the EM framework. The method is tested using synthetic and real datasets and shows good performance. 相似文献

Infants’ emerging ability to move independently by crawling is associated with changes in multiple domains, including an increase in expressions of anger in situations that block infants’ goals, but it is unknown whether increased anger is specifically because of experience with being able to move autonomously or simply related to age. To examine the influence of locomotion on developmental change in anger, infants’ (N = 20) anger expressions during an arm restraint procedure were observed longitudinally at a precrawling baseline assessment and 2 and 6 weeks after the onset of crawling. Infant age at each crawling stage was unrelated to the frequency of anger expressed in response to arm restraint. At 6 weeks postcrawling onset, infants whose mothers rated them as temperamentally higher in distress to limitations, compared with those rated lower, showed a greater increase in the frequency of anger expressed during the arm restraint relative to earlier assessments and took longer to reduce the frequency of anger expressed when no longer restrained. Findings suggest that experience with autonomous crawling has an effect on anger expression, independent of age, and that a temperamental tendency to become distressed by limitations may exacerbate the effect of crawling on anger expression. 相似文献

An initial test and validation of a model predicting perceived organizational citizenship behaviors (OCBs) of lesbian and gay employees were conducted using structural equation modeling. The proposed structural model demonstrated acceptable goodness of fit and structural invariance across 2 samples (ns = 311 and 295), which suggested that altruistic OCB performance is precipitated by workplace outness. Furthermore, stigmatization salience and organizational climate for heterosexism predict levels of workplace outness. Organizational climate for heterosexism is negatively related to stigmatization salience. When the model was tested on 2 samples, all structural paths except 1 were significant. 相似文献
