We discuss higher-order adjustments for a quasi-profile likelihood for a scalar parameter of interest, in order to alleviate some of the problems inherent to the presence of nuisance parameters, such as bias and inconsistency. Indeed, quasi-profile score functions for the parameter of interest have bias of order O(1), and such bias can lead to poor inference on the parameter of interest. The higher-order adjustments are obtained so that the adjusted quasi-profile score estimating function is unbiased and its variance is the negative expected derivative matrix of the adjusted profile estimating equation. The modified quasi-profile likelihood is then obtained as the integral of the adjusted profile estimating function. We discuss two methods for the computation of the modified quasi-profile likelihoods: a bootstrap simulation method and a first-order asymptotic expression, which can be simplified under an orthogonality assumption. Examples in the context of generalized linear models and of robust inference are provided, showing that the use of a modified quasi-profile likelihood ratio statistic may lead to coverage probabilities more accurate than those pertaining to first-order Wald-type confidence intervals. 相似文献

This article analyses four cases of governance in Italian local welfare systems. Following Law 328/2000, the design and management of the social services system in Italy involve different public responsibility levels, mainly regional and municipal. In order to manage social policies, Italian municipalities have to join in new inter‐municipal groupings called ‘Piani di Zona’ (Area Plans). Moreover, the law provides for engaging in these Plans even local third‐sector organizations and citizens. The article attempts to highlight the implications of this complex system that is leading local authorities to open new governance arenas. We hereby present the results of a research project on two Piani di Zona in the Region of Lombardy (Northern Italy) and on two in the Region of Campania (Southern Italy), carried out by means of institutional analysis. We particularly focus on the dynamics of participation triggered by the Piani di Zona. Our hypothesis is that the role of public administration is a fundamental variable to understand the different ways of participating. In this sense, we discuss the dynamics of local governance by relaying them to four main questions: who participates in what, where and how? 相似文献

The authors examine the literature with respect to the pricing of initial public offerings and focus upon the relationship
of pricing to the structure and conduct of the investment banking industry. Using a data base of all share offerings undertaken
in the United States over a two and a half year period, the authors find that there is considerable evidence for the proposition
that large, prestigious, and well capitalised investment banks tend to price their share offerings at a higher absolute level
than those not meeting such characteristics. Using classical statistical methods, the authors find that the pricing strategy
of investment banks is connected to their affiliation with investment funds and unit trusts. The motives for such pricing
strategies, the authors argue, lie with the affiliation of investment banks with investment funds, suggesting that the pricing
of new share offerings may be a means of excluding retail investors from participating in the strong returns such issues exhibit. The authors raise legal and regulatory implications
of their findings in the context of the general consolidation observed within the investment banking industry.

Private organizations increasingly wield public authority, with substantial impact on the lives of individual persons. Such authority is often paired with enhanced public scrutiny and decreased trust in the relevant organization, leading to a loss of legitimacy. This paper uses sports governing bodies to contribute to the literature on governance by developing theory on the interaction between organizational legitimacy and pathological internal structures. It takes a nuanced view of legitimacy and extends a model of organizational pathology. While primarily conceptual, the paper uses the well‐documented cases of the International Olympic Committee and, to a lesser extent, FIFA to illustrate how organizational pathology can not only undermine an organization's legitimacy, but can also interfere with its ability to perceive a path to legitimacy repair, even when it recognizes the necessity of doing so. The paper concludes with recommendations for practice and suggestions for future research looking beyond sports governing bodies. 相似文献

Communication scholars conceptualize communication as constitutive of meaning, arguing that we must place communication first as a primary, fundamental explanation, not as a secondary phenomenon to be explained by psychological antecedents (Cooren, 2012; Craig, 1999; Hecht, 1993; Luhmann, 1992; Manning, 2014). The present study uses a constitutive communication approach to model the relationship of listening to the cognitive states of hope, emotional intelligence, stress, and life satisfaction. A path analysis model lends support to the constitutive communication perspective, indicating that listening styles are predictive of hope, emotional intelligence, stress, and life satisfaction. 相似文献

This article conceptualises the role of emotion in social work home visits. It draws on findings from a qualitative study of initial child protection home visits in the United Kingdom. The research used narrative interviews and focus groups to examine how emotions arising from visits were registered in social workers' narratives. These visits were often challenging; social workers needed to manage their own emotions and those of the family, while at the same time investigating concerns and assessing need. This article identifies seven key emotional experiences associated with the home visit from the perspective of the social worker: going into the unknown; being intrusive; being disliked; fear of harm to self; fear of causing or allowing harm; pain, disgust, and distress; and “absorbing” emotion. It is argued that emotion plays a central role in home visiting and that professionals' emotional responses have important implications for the way they make sense of, and manage, home visits. Emotion is therefore conceptualized as both a potential resource and risk for social workers' professional judgement and practice. 相似文献

This paper reviews the past 28 years of scholarship on management consulting to synthesize the field and establish more broadly its contribution to management research. Through a systematic review of 219 articles, we identify three core conceptual themes – knowledge, identity, and power – that have dominated the literature to date. Through a thematic inductive analysis of a subsection of articles, we then investigate how these themes have been defined, used, and linked. This allows us to uncover and problematize the relationships between these themes. In making explicit underlying theoretical assumptions and relationships between knowledge, identity, and power, we induce a unique framework that can guide and support future studies, instigate metaparadigmatic dialogue, and thus help consolidate the field. 相似文献

This study examined the psychometric properties of the Self-Appraisal of Change Scale, a measure designed to capture domains that are subjectively relevant to caregivers, associated with overall well-being, and amenable to change upon engaging in an intervention. Data from 107 caregivers of veterans with dementia enrolled in a randomized controlled trial of a telephone-delivered caregiver psychoeducation and support group program (the Telehealth Education Program (TEP)) were analyzed. The TEP, which was delivered by master’s prepared social workers and a nurse dementia care manager, targeted caregivers’ dementia-related knowledge, attitudes, and self-management skills. Analyses were conducted to determine the factor structure, reliability, validity, and measurement invariance of the scale. Factor analyses yielded a single-factor solution for the scale’s nine items. The reliability and construct validity of the scale were also supported by the analyses. Multi-group analyses suggested that meaningful comparisons of scale items and total raw scores can be made across usual care (UC) and intervention groups. The findings offer preliminary support that the scale may represent a valid and reliable instrument that captures perceived changes in key domains (e.g. caregiving knowledge, attitudes, and skill) following participation in a psychoeducational and support intervention trial. 相似文献

An examination of the history of suburbanization in the United States shows that the suburban ideal has, from its beginnings, been associated with a vision of family togetherness, meaning that husband, wife, and children choose to spend their leisure time with one another. While the migration to the suburbs has been in part fueled by a desire to escape the mix of classes and ethnic groups of urban areas, and by government- and market-shaped economic incentives, the suburban ideal has stressed finding an environment in which family ties can be strengthened. The social and spatial structure of suburbia promotes familial isolation through a lack of public space and through an emphasis on home maintenance and home-centered entertainments. It is argued that by providing such optimal conditions for togetherness, suburbia may actually undermine familial harmony by exacerbating the strain of trying to live up to an essentially unattainable ideal. 相似文献
