Development of a carpal tunnel syndrome screening method using structured interviews and vibrotactile testing

Carpal tunnel syndrome (CTS) is a debilitating and expensive health problem. An inexpensive screening method that would differentiate between people who do not have CTS and those that may have CTS would be useful. The screening methodology investigated here had two phases: a structured interview and provocative vibrotactile testing (VT). The control group (n = 36) was composed of asymptomatic college students and faculty, the case group was composed of patients currently visiting an occupational medicine clinic for symptoms consistent with CTS. The case group was subdivided into positive and negative for nerve conduction latency, NCL+ (n = 21) and NCL- (n = 13), respectively. Using a scored, structured interview, 33 of the controls and none of the symptomatic cases were identified as non-CTS. The results from the provocative flexion VT indicated that if the difference between the age corrected baseline and the threshold at 15 minutes is 15 microm or more, the subject was likely to be NCL+ (odds ratio 12.6, 95% CI 3.8 to 41.8). Further research may improve this screening methodology to not only determine whether or not a person has CTS, but also to determine the level of median nerve impingement or damage.     

Bootstrap Determination of the Co‐Integration Rank in Vector Autoregressive Models

This paper discusses a consistent bootstrap implementation of the likelihood ratio (LR) co‐integration rank test and associated sequential rank determination procedure of Johansen (1996). The bootstrap samples are constructed using the restricted parameter estimates of the underlying vector autoregressive (VAR) model that obtain under the reduced rank null hypothesis. A full asymptotic theory is provided that shows that, unlike the bootstrap procedure in Swensen (2006) where a combination of unrestricted and restricted estimates from the VAR model is used, the resulting bootstrap data are I(1) and satisfy the null co‐integration rank, regardless of the true rank. This ensures that the bootstrap LR test is asymptotically correctly sized and that the probability that the bootstrap sequential procedure selects a rank smaller than the true rank converges to zero. Monte Carlo evidence suggests that our bootstrap procedures work very well in practice.     

Exploring the role of supervisor trust in the associations between multiple sources of relationship conflict and organizational citizenship behavior

We develop and test a model that builds directly on social exchange theory to predict different roles for supervisor trust in the relationships between organizational citizenship behavior and relationship conflict occurring between supervisors and subordinates and between peers. Specifically, we posit that the association between citizenship behavior and relationship conflict between employees and supervisors is mediated by supervisor trust, while the association between citizenship behaviors and relationship conflict occurring between peers is moderated by supervisor trust. We test our dual role for supervisor trust in a field study of 160 supervisor–employee dyads. Results support the different roles played by supervisor trust. We close by discussing the implications of our results for theory and practice in the relationship conflict and citizenship domains.     

Monitoring Optimism in South Africa

The last two decades have been the most crucial and eventful ones in South Africa's history. During this time, the empirical research and knowledge provided by opinion polls yielded much-needed insight into the grass roots of a society in transition, providing an instrument with which to measure the political climate, to observe trends and developments, and to give input into the decision-making process of companies and political parties. Although the process of change and political transition still remains difficult to define properly, this article will provide some insight into the attitudes, perceptions and values of the South African public, by giving attention to trends that have transpired over the years. Special attention is devoted to perceptions on pertinent issues such as the mood in the country, optimism, economic well-being, social harmony and trust – all essential elements in an emerging democracy. Extensive use is made of data and findings of Markinor's bi-annual Socio-Political Trends surveys, the World Values Studies and the annual Gallup End-of-Year Poll.     

The best-laid schemes: An analysis of discrepancies between migration intentions and behavior

A longitudinal survey approach is used in a largely rural area in the Philippines to examine consistency between migration intentions and subsequent migration behavior. Inconsistencies in movement behavior, the timing of a move, and the destination are analyzed. Discrepancies between intentions and behavior are explained in terms of unanticipated constraints and facilitators as well as changes in the conditions that precipitated the migration intention in the first place. Intended international movers who did not actually move in a 2-1/2 year period were thwarted mainly by legal hurdles that could not be overcome. Intended internal migrants who did not actually move remained in their origin area primarily because of changes in job opportunities or family relationships. Methodological and theoretical implications of the findings are discussed.The best laid schemes o' Mice an' Men Gang aft agley, An' la'e us nought but grief an' pain, For promis'd joy! we must bear in mind the distinction between direct and facilitating factors involved in migration processes . migration analysis should consider some factors that facilitate or impede migration rather than determine migration directly (Goldscheider, 1971:38).This article was originally presented at the annual meetings of the Population Association of American in Minneapolis, Minnesota, May 2–5, 1984.

Correlates of gay and lesbian couples' relationship satisfaction and relationship dissolution

A sample of committed gay and lesbian cohabiting couples engaged in two conversations after being apart for at least 8 hours: (a) an events of the day conversation and (b) a conflict resolution conversation. Physiological data were collected during the conversations and a videotape record was made. Couples viewed the videotapes and rated their affect during the interaction. The video records were coded with a system that categorized specific affects displayed. Models derived from physiology, from the perception of interaction, and from specific affective behavior were related to relationship satisfaction, and to the prediction of relationship dissolution over a 12-year period. Results supported previous findings that satisfaction and stability in gay and lesbian relationships are related to similar emotional qualities as in heterosexual relationships.     

Things visible and invisible: the Leather Archives and Museum

This paper explores the reasons underlying the relative absence of research on the leather/levi community in gay and lesbian studies and summarizes the history and special collections of Chicago's Leather Archives and Museum.
