The Use and Validation of Preintervention Diagnostic Tools in Organizational Behavior Management

Functional analyses and assessments have become the accepted gold standards in many applied areas of behavior analysis, including Organizational Behavior Management (OBM), in recent years. Despite their acceptance, OBM data on such tools have been largely absent. There are several assessment alternatives in OBM (e.g., ABC, PIC/NIC, Behavior Engineering Model), but two assessment approaches most common in the Journal of Organizational Behavior Management are Behavioral Systems Analysis (BSA) and the Performance Diagnostic Checklist (PDC). To date there have been no comprehensive reviews of BSA or the PDC from which one might draw ideas for application, research, and the advancement of the field. The goals of this paper are to (a) provide a review of the BSA and PDC literature within the Journal of Organizational Behavior Management (JOBM), (b) discuss the implications of the results of the review, and (c) provide suggestions for future research utilizing BSA and the PDC.     

A Psychometric Evaluation of the DSM-IV Pathological Gambling Diagnostic Criteria

Specific diagnostic criteria for pathological gambling (PG) have been available for 25 years, since the publication of DSM-III. Little research has examined the psychometric performance of the diagnostic criteria. The goal of the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project was to examine the sensitivity, specificity and predictive values of the DSM-IV PG criteria for psychiatric outpatients who screened positive for a gambling problem. A total of 1709 psychiatric outpatients were evaluated with a semistructured diagnostic interview for PG. Of all patients 88 screened positive for PG, 40 of whom met DSM-IV diagnostic criteria for a lifetime history of PG. All ten DSM-IV criteria were significantly more frequent in the PG group. The sensitivity of the criteria ranged from 25.0% to 90.0% (mean = 67.8%), whereas specificity ranged from 62.5% to 100% (mean = 81.9%). Positive predictive values ranged from 64.1% to 100% (mean = 78.9%), and negative predictive values ranged from 61.5% to 90.7% (mean = 77.1%). Guidelines are recommended for determining whether a diagnostic criterion should be retained as part of the set of diagnostic criteria, and our results suggested that two of the DSM-IV PG criteria are candidates for elimination (criterion 8—commitment of illegal acts; criterion 10—reliance on others for financial assistance to relieve a desperate financial problem).     

Controversies in Sexuality Courses at Colleges and Universities in the 1990s

Summary

Sexuality educators have always had to face issues not typically encountered by those teaching other subjects. Over the past 25 years, the general social climate at colleges and universities has been supportive of sexuality education and has had a role in shaping sexuality courses. However, contemporary higher education and the sociopolitical climate of North America now present major challenges to sexuality education, greatly complicating the role of the sexuality educator. Among the many changes in climate, the single most significant difference may be a shift away from an emphasis on providing a personally enriching experience to an emphasis on providing a personally safe environment for all students. The implications of this are briefly discussed and illustrated.     

A note on diagnostic checking of the double autoregressive model

The double autoregressive model finds its use in the modelling of conditional heteroscedasticity of time series data. In view of its growing popularity, the goodness-of-fit of the model is examined. The asymptotic distributions of the residual and squared residual autocorrelations are derived. Two test statistics are then constructed which can be used to measure the adequacy of the conditional mean and conditional variance components of a fitted model. Our goodness-of-fit tests out-perform other benchmark tests such as the Ljung–Box test in simulation studies. To illustrate the testing procedure, the model is fitted to the weekly log-return series of the Hang Seng Index.     

Regression Analysis of Longitudinal Data with Time‐Dependent Covariates and Informative Observation Times

Abstract. Longitudinal data frequently occur in many studies, and longitudinal responses may be correlated with observation times. In this paper, we propose a new joint modelling for the analysis of longitudinal data with time‐dependent covariates and possibly informative observation times via two latent variables. For inference about regression parameters, estimating equation approaches are developed and asymptotic properties of the proposed estimators are established. In addition, a lack‐of‐fit test is presented for assessing the adequacy of the model. The proposed method performs well in finite‐sample simulation studies, and an application to a bladder tumour study is provided.     

Adjusting ROC curves for covariates in the presence of verification bias

The ROC (receiver operating characteristic) curve is frequently used for describing effectiveness of a diagnostic marker or test. Classical estimation of the ROC curve uses independent identically distributed samples taken randomly from the healthy and diseased populations. Frequently not all subjects undergo a definitive gold standard assessment of disease status (verification). Estimation of the ROC curve based on data only from subjects with verified disease status may be badly biased (verification bias). In this work we investigate the properties of the doubly robust (DR) method for estimating the ROC curve adjusted for covariates (ROC regression) under verification bias. We develop the estimator's asymptotic distribution and examine its finite sample size properties via a simulation study. We apply this procedure to fingerstick postprandial blood glucose measurement data adjusting for age.     

论保险人的调查义务

在实践中,我国保险业时常出现保险人自身未尽相关调查义务而以投保人未尽告知义务为由恶意拒赔的现象,我国保险法却没有对保险人调查义务作出相应的规定。因此,我国保险法律应对保险人调查义务的相关问题予以明确规定,这对于平衡保险合同双方当事人的权利义务关系以及促进我国保险事业健康有序发展都有着至关重要的意义。
