Humean dispositionalism

Humean metaphysics is characterized by a rejection of necessary connections between distinct existences. Dispositionalists claim that there are basic causal powers. The existence of such properties is widely held to be incompatible with the Humean rejection of necessary connections. In this paper I present a novel theory of causal powers that vindicates the dispositionalist claim that causal powers are basic, without embracing brute necessary connections. The key assumptions of the theory are that there are natural types of causal processes, and that manifestations of powers are identified with certain kinds of causal processes. From these assumptions, the modal features of powers are explained in terms of internal relations between powers themselves and the process-types in which powers are manifested.     

Relevant Restricted Quantification

The paper reviews a number of approaches for handling restricted quantification in relevant logic, and proposes a novel one. This proceeds by introducing a novel kind of enthymematic conditional.     

A Test of Two Positive Psychology Interventions to Increase Employee Well-Being

Purpose

Despite an abundance of organizational research on how contextual and individual difference factors impact well-being, little research has examined whether individuals themselves can take an active role in enhancing their own well-being. The current study assessed the effectiveness of two simple, self-guided workplace interventions (“gratitude” and “social connectedness”) in impacting well-being.

Design/Methodology/Approach

Sixty-seven university employees participated in one of the two self-guided interventions for 2 weeks and completed self-report measures prior to the intervention, immediately following the intervention, and one-month post-intervention. Growth curve modeling was used to examine the effects of each intervention.

Findings

Partially supporting hypotheses, the gratitude intervention resulted in significant increases in positive affective well-being and self-reported gratitude but not did significantly impact negative affective well-being or self-reported social connectedness. The social connectedness exercise did not significantly impact any of those four outcomes. However, both interventions related to a reduction in workplace absence due to illness.

Implications

The study suggests that self-guided, positive psychology interventions (particularly gratitude) hold potential for enhancing employee well-being. Because the interventions are short, simple, and self-guided, there is little in the way of costs or drawbacks for organizations. Thus, these types of interventions seem like a potentially useful component of workplace wellness initiatives.

Originality/Value

This study is one of the few to examine whether self-guided, positive psychology interventions can enhance well-being. Moreover, this is the first study to examine a social connectedness workplace intervention and the first to demonstrate effects on illness-related absence.     

Moral credentialing by association: the importance of choice and relationship closeness

People express more prejudice if they have established their "moral credentials." Five studies explored the acquisition of moral credentials through associations with racial minorities, particularly close relationships that are personally chosen. Participants choosing to write about a positive experience with a Black person (Study 1) or Hispanic person (Study 2) subsequently expressed more preference for Whites and tolerance of prejudice than did other participants. In Study 3, the credentialing effect of choice was diminished when participants were given an incentive for that choice. Participants in Study 4 who wrote about a Black friend were more credentialed than those who wrote about a Black acquaintance, regardless of whether the experience was positive or negative. Study 5 suggested that participants strategically referred to close associations with minorities when warned of a future situation in which they might appear prejudiced.     

Homogeneity of Personality in Occupations and Organizations: A Comparison of Alternative Statistical Tests

Purpose

The attraction?Cselection?Cattrition (ASA) model has served as the foundation for numerous investigations. However, the generally supportive evidence for ASA??s homogeneity hypothesis has often been based on statistical tests (e.g., MANOVA) that rely on between-group differences to evaluate within-group agreement. The primary purpose of this article was to discuss advantages of direct statistical tests of homogeneity??average deviation (AD) and r _wg??when testing ASA??s homogeneity hypothesis, and advantages of other statistical tests for testing other aspects of ASA theory. A secondary goal was to evaluate the extent to which occupational homogeneity is distinct from organizational homogeneity.

Design/Methodology/Approach

Data were obtained from the Center for Creative Leadership (CCL) and included scores on the Myers-Briggs Type Indicator^? (MBTI) personality measure for 1,103 managers from 25 organizations and 17 occupations.

Findings

Results were generally supportive of the homogeneity hypothesis. AD values showed that most groups were homogeneous on most assessed personality dimensions. A comparison analysis using traditional statistical tests (i.e., MANOVA) indirectly suggested within-group homogeneity by revealing a significant between-groups effect. In addition, results suggested possible boundary conditions to ASA; notably, meaningful heterogeneity was observed for the S?CN (sensing-intuition) MBTI^? dimension.

Implications

The current study provides direct support for ASA??s homogeneity hypothesis for both organizations and occupations and offers guidance for future research on ASA theory and its possible boundary conditions.

Originality/Value

This is one of the first studies to test the predictions of ASA in both organizations and occupations using a direct index of agreement.
