Abstract One of the defining elements of a profession is its capacity to generate and transmit knowledge about practice. This paper reviews and assesses the state of scholarship and research in social work through diverse perspectives, among them research methods found in the core literature, the scholarly productivity of faculty and doctoral graduates, the research curricula in graduate programs, and the use of scholarship by practitioners. Finally it posits challenges for improving the profession's research training, scholarly production, and knowledge transmission. 相似文献

Pansexuality, characterized by attraction to people regardless of their gender, is an emerging sexual identity. Research has started to explore the differences between those who identify as pansexual and those who identify as bisexual, typically defined as being attracted to both men and women. This article extends past research by testing for differences between those who identify as pansexual (n = 52) and bisexual (n = 497) in a nationally representative sample. We used the New Zealand Attitudes and Values Study (NZAVS) to test for differences in demographic variables, psychological well-being, and political ideology. We found that pansexual participants were younger, more likely to be gender diverse (transgender or nonbinary), and more likely to be from the indigenous Māori ethnic group than bisexual participants. Pansexual participants also reported higher psychological distress and were more politically liberal than bisexual participants. These results suggest that people who identify as pansexual are, on average, quantifiably different from those who identify as bisexual; this study adds to a new but growing body of research on emerging plurisexual identities. 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

The demographic study of aboriginal populations in Australia has been somewhat neglected until the last two decades. The historical study of aboriginal groups, from either the perspectives of epidemiology, morbidity or longevity, as a consequence has received little attention by health, education or welfare professionals until more recently. Some of the current studies, reviewed in this article, link historical approaches made in earlier studies in documenting the ‘dwindling’ presence of Australia's original inhabitants. Recent research highlights a gradually increasing public interest in a supposedly or even theoretically ‘contracting minority group’ with some disturbing implications for government policy‐makers. 相似文献

“Chasing” behavior, whereby individuals, driven by a desire to break even, continue a risky activity (RA) despite incurring large losses, is a commonly observed phenomenon. We examine whether the desire to break even plays a wider role in decisions to stop engaging in financially motivated RA in a naturalistic setting. We test hypotheses, motivated by this research question, using a large data set: 707,152 transactions of 5,379 individual financial market spread traders between September 2004 and April 2013. The results indicate strong effects of changes in wealth around the break‐even point on the decision to cease an RA. An important mediating factor was the individual's historical long‐term performance. Those with a more profitable trading history were less affected by a fall in cash balance below the break‐even point compared to those who had been less profitable. We observe that break‐even points play an important role in the decision of nonpathological risk takers to stop RAs. It is possible, therefore, that these nonpathological cognitive processes, when occurring in extrema, may result in pathological gambling behavior such as “chasing.” Our data set focuses on RAs in financial markets and, consequently, we discuss the implications for institutions and regulators in the effective management of risk taking in markets. We also suggest that there may be a need to consider carefully the nature and role of “break‐even points” associated with a broader range of nonfinancially‐focused risk‐taking activities, such as smoking and substance abuse. 相似文献

Game theory has provided many tools for the study of social conflict. The 2 × 2 game has been found to be a particularly useful model. This paper describes the enumeration and analysis of all 726 distinct 2 × 2 games. A computer is used to generate the complete set, and a wide variety of maximin, equilibrium and stability calculations is performed for each player for every outcome in every game. The resulting data set is of great value for both the modeling and analysis of social conflict. 相似文献

Approximate conditional inference for a real parameter in the presence of nuisance parameters was examined from a sample-space
differential viewpoint in Fraser and Reid (1988) and a conditional inference procedure was proposed. Conditional likelihood-based
inference in the same setting was discussed in Cox and Reid (1987), where emphasis was placed on orthogonalizing the nuisance
parameter to the parameter of interest. In this paper the sample-space partitions of the two methods are examined for the
case that the minimal sufficient statistic has the same dimension as the parameter space. The methods are identical if observed
and expected information gives the same orthogonality; an example indicates how they can differ more generally. A specially
chosen reparameterization provides some geometrical insight to the methods and allows a comparison in terms of score functions
and locally defined orthogonal parameters. 相似文献

The concept of distribution form developed in Brenner and Fraser (1980) is modified and extended to cover the more general context involving a class of distribution for form. This extension underlies the choice of a particular structural model for the three-parameter Weibull in Evans, Fraser and Massam (1982). The extended definition of distribution form is based on the requirement of objectivity in modelling (Fraser 1979). Three characterizations of this objectivity each require that the class of response presentations have closure under composition and thus be expressible in terms of a group. In particular, this implies that empirical support would not observationally be available for that generalization of a structural model called astructured model (Fraser 1972; the term functional model has been used inappropriately by Bunke, 1975 and Dawid and Stone, 1982). 相似文献
