Semi-parametric extended Poisson process models for count data

A general framework for the analysis of count data (with covariates) is proposed using formulations for the transition rates of a state-dependent birth process. The form for the transition rates incorporates covariates proportionally, with the residual distribution determined from a smooth non-parametric state-dependent form. Computation of the resulting probabilities is discussed, leading to model estimation using a penalized likelihood function. Two data sets are used as illustrative examples, one representing underdispersed Poisson-like data and the other overdispersed binomial-like data.     

Heterosexually married men who have sex with men: marital separation and psychological adjustment

There have been few investigations of sexual identity and psychological adjustment among behaviorally-bisexual married men. A critical issue is whether such men experience increased psychological adjustment if they exit their primary heterosexual relationship and assume a gay identity. Two hundred and one ever-married men (n = 201) with same-sex sexual interests and behaviors were administered the Brady and Busse (1994) gay identity development questionnaire (GIQ) and the symptom check list-90 (SCL-90) as part of a larger investigation of sexual identity development. The measurement of homosexual identity formation (HIF) using the original nominal scoring criteria for the GIQ did not adequately detail processes of HIF among respondents, and an alternative scoring system that allowed continuous, rather than stage, measurement of HIF was utilized. Psychological adjustment was found to be significantly correlated with HIF among ever-married gay-identified men. Within bisexual-identified men, no relationships between HIF and psychological adjustment were found. Future studies of HIF should clearly differentiate between gay and bisexual men. The findings suggest significant psychological gains accompany public affirmation of gay identity among self-identified gay men who have been in a previous heterosexual relationship.     

The average likelihood and a fiducial approximation: one parameter members of the generalized gamma distributions

The average likelihood, defined as the integral of the like-lihood function over the parameter space, has been used as a criterion for model selection The form of the average likelihood considered uses a uniform prior. An approximation is presented based on fiducial distributions. The sampling distributions of the average likelihood and its fiducial approximation are derived for cases of sampling from one parameter members of the general-ized gamma distributions.     

Ballot theorem and lattice path crossings

We consider lattice paths which cross the diagonal exactly r times, and by a simple method determine the number of such paths when the endpoint is given. Then as a byproduct we easily obtain Feller's (1968, p.84) result for crossings when the length is given.     

Powerless Children—Powerful Systems

This article looks at the needs of children and families now that there is increasing inter-agency conflict. The situation is considered from the perspective of one agency, educational psychology and it is suggested that the pressures on one agency are common to all agencies. It is argued that the impact of the changes imposed upon agencies conspires to enhance the power of systems and diminish opportunities for children and families to be in control. Examples of effective inter-agency support and a model of working that facilitates positive outcomes for children and their families are discussed.     

Representation elections in higher education: Occurrence and outcomes

This study examines factors related to the occurrence of union representation elections in four-year universities and colleges and the outcomes of those elections (i.e., whether or not faculty opt for collective bargaining). In general, the results indicate that the probability of union victory in an election depends on economic conditions, the structural characteristics of the institution, and union density in higher education. For the most part, however, such indicators of institutional vulnerability are not found to be significant determinants of election occurrences. A major implication of this study is that there is a need to investigate more thoroughly the intraorganizational processes of faculty unions with regard to the allocation of organizing resources in order to understand the spread of faculty unionism. It is also suggested that the findings of this study may cast light on the growth of unionism in other white-collar and professional sectors. The authors are grateful to James L. Perry, Jeffrey Pfeffer, Claudia Bird Schoonhoven, and an anonymous reviewer for comments on an earlier version. The research assistance of Ken Bergstrom is also acknowledged.     

Critical Commentary: Happy Shopper? The Problem with Service User and Carer Participation

This critical commentary assesses the consequences and impactof forms of seemingly widespread, constructive and altruisticservice user and carer participation (SUCP) within social work.In particular, and whilst drawing from Gramsci's understandingof hegemony and Levitas's critical interpretation of socialexclusion, it is proposed that SUCP serves the interests ofgovernment, affiliated organizations, including those withinsocial work and social care, and, perhaps more generally, thedisparate needs generated by the neo-liberal-inspired socialcare market. Arguably, there are also related substantive aspectsof SUCP that are problematic on ethical grounds—includingthe possibility that participation inadvertently increases socialinequalities by justifying and promoting hegemonic agendas.Some suggestions are briefly made regarding how to move SUCPforward, including difficult questions that must be asked aboutwhether or not SUCP can confront forms of structural disadvantageand oppression.     

UK Competition Policy and Shareholder Value: The Impact of Merger Inquiries

Some previous studies have suggested that competition régimes can destroy shareholder value. This study examines data on 50 mergers in the UK between 1989 and 2002. The study confirms the finding from earlier studies of greater gains to shareholders in target than bidding companies, but does not find evidence supporting overall loss of shareholder value to target company shareholders when a merger is prohibited. It finds evidence that when the regulatory régime is stable and well understood the capital market behaves efficiently in response to new information. However, for a subgroup of the mergers involving companies with a new regulatory régime, where the industry and the stock market had little or no experience with respect to mergers, the capital market operated less efficiently.
