ASYMPTOTIC TESTS FOR GROWTH CURVE MODELS WITH AUTOREGRESSIVE ERRORS

This paper presents the limit distribution (as the number of time points increase) for the score vector of a growth curve model assuming both stationary and explosive autoregressive (A.R.) errors. Limit distributions of the score statistic and the likelihood-ratio statistic for testing composite hypotheses about the regression parameters of several growth curves, when the autocorrelation parameters are treated as nuisance parameters, are presented.     

Ergonomics in a hospital and a university setting: The effect of worksite analysis on upper extremity work-related musculoskeletal disorders

OBJECTIVES: The purpose of this study was to determine whether individuals with work-related injuries receiving worksite analysis would have less lost workdays than individuals not receiving worksite analysis. Therapeutic management of work-related injuries in a hospital and a university setting were also compared. STUDY DESIGN: Over a one-year period, employees who sustained an upper extremity work-related injury were issued questionnaires regarding their injury, treatment, functional status and pain level. Participants were divided into three groups: group 1 consisted of hospital employees (N=14) who underwent worksite analysis, group 2 included university employees (N=15) who underwent worksite analysis whereas group~3 included university employees (N=14) who underwent no analysis. RESULTS: All groups were similar in demographics, functional status, and pain level. Satisfaction with the worksite analysis was similar for groups one and two. CONCLUSION: A pattern of less absenteeism but greater modified duty days was associated with those individuals undergoing worksite analysis.     

Seeing the Case Clearly: File‐Work,Material Mediation,and Visualizing Practices in a Dutch Criminal Court

In Dutch criminal courts, judges and their assisting clerks spend significant amounts of time doing file‐work in preparation for the court hearing: a practice they often call “visualizing the case.” This practice is distributed over clerks and judges and materially mediated: the legal case file enters into face‐to‐file interaction as both a text and a material object. This article aims to unpack what techniques clerks and judges draw on in order to come to “see the case clearly,” while at the same time it elaborates on the renegotiations of these largely paper‐based practices when court workers are confronted with the digitization of case files.     

The Re-Creation Of Gender In A Male Workplace

This paper draws on participant observation in a male-dominated blue-collar job to understand how the concepts of masculinity and femininity are re-created through coworker interactions on the shopfloor and the effect of this on women. Men typecast women in these jobs as either feminine or unfeminine and treated them differently, but in both cases, women's presence was useful for defining–and in the case of sex-role appropriate women–enforcing masculinity. Such treatment isolated women from the on-going work culture and constrained them to certain behaviors.     

Uncommon Priors Require Origin Disputes

In standard belief models, priors are always common knowledge. This prevents such models from representing agents’ probabilistic beliefs about the origins of their priors. By embedding standard models in a larger standard model, however, pre-priors can describe such beliefs. When an agent’s prior and pre-prior are mutually consistent, he must believe that his prior would only have been different in situations where relevant event chances were different, but that variations in other agents’ priors are otherwise completely unrelated to which events are how likely. Due to this, Bayesians who agree enough about the origins of their priors must have the same priors.     

Agricultural Restructuring and the Spatial Dynamics of U.S. Women's Employment in the 1970s1

Abstract The spatial rearrangement of women agricultural workers' employment across 380 labor market areas is examined during the period of agricultural transformation in the 1970s. Labor market maps of women's employment changes show regional declines and increases in accord with the dynamics of agricultural industrialization. Case studies selected from the maps demonstrate the gender-specific and locality-specific ramifications of these transformations.     

Individualism and conformity in the 1950s vs. the 1980s

If the 1950s are remembered for conformity, the 1960s for rebellious individualism, and the 1970s for narcissistic individualism, images of the 1980s contain an ambiguous mixture of individualism and conformity, with similarities to the 1950s. But if the 1980s resemble the 1950s in some respects, are portraits of individualism and conformity in the later decade nevertheless different from their earlier incarnations? A comparative analysis of best-selling self-help books in the 1950s and the 1980s reveals the following changes: from “maturity” as a desirable end to an ever-changing self; from determinism about the self to antideterminism and constructionism; from institutional constraints and joys to interpersonal ones. These changes reflect the incorporation of ideas from the counterculture of the late 1960s and early 1970s, and may also stem from perceptions of a simultaneous increase in structural determinism and individual empowerment.
