Defending truth values for indicative conditionals

Philosophical Studies - There is strong disagreement about whether indicative conditionals have truth values. In this paper, I present a new argument for the conclusion that indicative conditionals...     

Enhancing social diffusion theory as a basis for prevention intervention: A conceptual and strategic framework

Social diffusion theory has recently been recognized as a promising approach for large-scale disease prevention and health promotion efforts. This paper describes how principles and tactics from social cognitive theory, operant psychology, social psychology, social marketing, and the overarching stages of change model can be used to further develop the conceptual and strategic (technological) bases of social diffusion theory. Within an integrative framework, we discuss in detail more effective ways to train peer mediators of behavior change as one example of how social diffusion theory can benefit from this conceptual and strategic reformulation. We then further illustrate the use of peer mediators of change in human immunodeficiency virus (HIV) and cancer prevention intervention studies with both interventions training peer mediators to diffuse information, norms, and risk reduction strategies. Although the results of these studies showed reductions in high-risk behaviors across population segments, more closely following the framework discussed in this article should further increase the behavior change potential of future interventions based on social diffusion theory.     

Reexamining the demand for HR certification in the United States

Given the addition of new Human Resources (HR) certification offerings by the Society for Human Resource Management and the increase in HR certifications being awarded by the HR Certification Institute, it is necessary to investigate the current rate of demand for HR certification and explore practical implications for those within the field. The current study analyzed over 5,300 HR job announcements and found 20.7% demanded (preferred and/or required) HR certification with more requiring HR certification than before. Additionally, HR certification demand was positively related to salary, experience, education level, and job title with demand reaching 33.7% for managerial HR roles.

Posttraumatic Stress Disorder Symptom Clusters and Acquired Capability for Suicide: A Reexamination Using DSM-5 Criteria

This study used the interpersonal–psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS.     

Automaticity in reading and the Stroop task: testing the limits of involuntary word processing

We investigated the parameters of involuntary word reading in the Stroop task in 7 experiments. Experiments 1-4 varied response modality and the presence of congruent word trials in a test of the claim that presenting a Stroop color word with only one letter in the target color eliminates the Stroop effect. Experiments 5 and 6 addressed the roles of spatial attention and orthographic processing as possible mechanisms behind the reduction of Stroop effects with the single-letter format. Experiment 7 investigated the limits of involuntary reading under optimal conditions for selective processing of rectangular color patch targets. We found that the single-letter format reduced but never eliminated Stroop effects, spatial attention but not orthographic processing plays a role in the effect of the single-letter format, and word reading is not completely prevented even with austere presentation conditions. We conclude with a defense of the involuntariness criterion for automaticity in the Stroop task, particularly when word reading is viewed in the context of a skilled performance.     

Examination of residuals to Vancouver crisis call data by using hidden Markov models

Three years of daily crisis calls (N=2,513,478) were examined in a regression analysis with terms for effects for weekday, end and beginning of the month, holiday, seasonal trend, and long-term linear trend. This was followed by an analysis of residuals using hidden Markov models, with three states best fitting the residuals. These states may reflect economic or environmental variables which researchers should clarify in further work.     

Bulimic symptomatology,body-image,and personality characteristics of university men

This study examined the relationships, using regression analysis, among bulimic symptomatology, body-image characteristics, and personality factors in a nonclinical sample of 46 undergraduate university men. They completed the Bulimia Test-Revised (a measure of bulimic symptomatology), the Eysenck Personality Questionnaire-Revised (a measure of personality characteristics), and the Multidimensional Body-Self Relations Questionnaire (a multidimensional measure of body-image parameters). Statistically significant relationships were identified among Appearance Evaluation, Neuroticism, and Psychoticism, and the BULIT-R scores.
