On diagnostic checking of the autoregressive conditional intensity model

The autoregressive conditional intensity model proposed by Russell (1998) is a promising option for fitting multivariate high frequency irregularly spaced data. The authors acknowledge the validity of this model by showing the independence of its generalized residuals, a crucial assumption of the model formulation not readily recognized by researchers. The authors derive the large‐sample distribution of the autocorrelations of the generalized residual series and use it to construct a goodness‐of‐fit test for the model. Empirical results compare the performance of their test with other off‐the‐shelf tests such as the Ljung–Box test. They illustrate the use of their test with transaction records of the HSBC stock.     

A new Method of Estimating the Asymptotic Standard Error of the Hodges-Lehmann Estimator Based on Generalized Least Squares

A method of estimating the asymptotic standard error of the Hodges-Lehmann estimator based on generalized least squares is described. The results of a Monte Carlo study comparing the new method with existing ones are given.     

ANALYSIS OF DOUBLY CENSORED DATA AND THE HIV INCUBATION PERIOD DISTRIBUTION IN WESTERN AUSTRALIA

The paper analyses the distribution of times from HIV seroconversion to the first AIDS defining illness for a subcohort of the Western Australian HIV Cohort Study for whom the seroconversion date is known to fall within a calendar time window. The analysis is based on a generalised gamma model for the incubation times and a piecewise constant distribution for the conditional times of seroconversion given the seroconversion windows. This allows flexible hazard shapes and also allows comparison of goodness of fit of the gamma and Weibull distributions which are often used for modelling incubation times. Computational issues are discussed. In these data, neither age at seroconversion, nor calendar time of seroconversion, nor the identification of a seroconversion illness appears to afFect incubation distributions. The Weibull distribution appears to provide a reasonable fit. The distribution of times from seroconversion to an HIV-related death is also briefly considered.     

Respect,equality, and power: A social psychological perspective

In this article I outline a principled social psychological approach to respect. As a first definitional approximation, I suggest that respect for someone involves the willingness to include that person as a factor in the psychological equation underlying self-regulation. I then review and discuss the fairly recent, but thriving, career of the notion of respect in social psychological research, with particular emphasis on intragroup respect. Next, I turn to conceptual specification and purification necessary for a principled approach to respect and discuss promising efforts to identify the critical social psychological principle or active ingredient of respect. In particular, I make out a case for an equality-based conception of respect in which recognition as an equal plays a central role. The final section examines further theoretical and practical implications of this conception including its relation and relevance to issues of social power.

He studied psychology, sociology and philosophy at the University of Münster (Germany) and the University of Kent at Canterbury (England). In his research, Bernd Simon investigates inter-and intragroup processes, with particular emphasis on issues of identity, power, politicization and respect. He is author/co-author of a number of research articles in international journals and books, including Identity in Modern Society (Blackwell Publishing).

Barriers to returning to work for people with spinal cord injuries: a focus group study

The rate of employment for people with spinal cord injuries is relatively low, especially among Asians. To help individuals with spinal cord injuries return to work or retain employment, rehabilitation professionals must understand the barriers to employment and intervene to reduce or remove them. Hence, a focus group study was administered to 16 people with spinal cord injuries to explore return to work barriers. Various ideas, beliefs, responses, and values at different stages of work resettlement were elicited from both employed and unemployed participants, and then summarized. According to the results, several modifications of existing forms of rehabilitation intervention are necessary, as are further research directions.     

Seizing the means of reproduction: An illegal feminist abortion collective—How and why it worked

This paper describes an illegal feminist abortion collective [the Service] through whose efforts 11,000 abortions were performed between 1969 and 1973 when abortion was legalized. An analysis of interviews from 32 members of this lay group indicates how and why the collective was so effective in providing what is usually a physician-controlled medical procedure. After describing the structure of the organization and the process by which women obtained the abortion, including pre-abortion counseling and post-abortion follow-up, two sets of reasons for the collective's effectiveness are presented. The first five reasons derive from the interview themselves; they deal with the organization's social and historical context, its illegality, its charismatic leaders, its member satisfaction and its financial self-sufficiency. The next nine reasons deal with factors that make The Service a relatively typical democratic collective organization. The most important of these factors is its lack of concern for organizational survival per se. This account supports the Rothschild-Whitt model for collective democratic organizations. It also suggests that counseling is important both for the providers and for the receivers of abortions.
