Entropy,semantic relatedness and proximity

Although word co-occurrences within a document have been demonstrated to be semantically useful, word interactions over a local range have been largely neglected by psychologists due to practical challenges. Shannon’s (Bell Systems Technical Journal, 27, 379–423, 623–665, 1948) conceptualization of information theory suggests that these interactions should be useful for understanding communication. Computational advances make an examination of local word–word interactions possible for a large text corpus. We used Brants and Franz’s (2006) dataset to generate conditional probabilities for 62,474 word pairs and entropy calculations for 9,917 words in Nelson, McEvoy, and Schreiber’s (Behavior Research Methods, Instruments, & Computers, 36, 402–407, 2004) free association norms. Semantic associativity correlated moderately with the probabilities and was stronger when the two words were not adjacent. The number of semantic associates for a word and the entropy of a word were also correlated. Finally, language entropy decreases from 11 bits for single words to 6 bits per word for four-word sequences. The probabilities and entropies discussed here are included in the supplemental materials for the article.     

Antecedents and consequences of the frequency of upward and downward social comparisons at work

The current paper examines the dispositional and situational antecedents, as well as the attitudinal and behavioral consequences, of the frequency of upward and downward social comparisons. We predicted social comparison frequency would be influenced by uncertainty-related antecedents, and that social comparisons in organizations would be characterized by contrast, not assimilation, effects. A large and occupationally diverse sample of 991 employed adults was surveyed at three separate points in time over a 12–16 week period. Our results, based on structural equation modeling, indicated that (a) role ambiguity, task autonomy, and core self-evaluations were significant predictors of upward social comparison, (b) upward social comparison was significantly negatively related to job satisfaction and affective commitment, (c) downward social comparison was significantly positively related to job satisfaction and affective commitment, and (d) upward and downward social comparisons had significant positive and negative indirect effects on the frequency of job search behaviors, respectively. The findings are discussed in terms of their general implications for understanding the importance of directional social comparison processes in organizational settings.     

Organizational supports and organizational deviance: The mediating role of organization-based self-esteem

Drawing upon belongingness theory, we tested organization-based self-esteem (OBSE) as a mediator of the relation between organizational supports and organizational deviance. Data from 237 employees were collected at three points in time over one year. Using structural equation modeling, we found that OBSE fully mediated the relation between organizational supports and organizational deviance. Controlling for preexisting predictors of deviance, including personality traits (agreeableness, neuroticism and conscientiousness) and role stressors (role conflict, ambiguity, and overload), did not eliminate the relation between OBSE and organizational deviance. The implications for the OBSE and deviance literatures are discussed.     

The Influence of Work Personality on Job Satisfaction: Incremental Validity and Mediation Effects

ABSTRACT Drawing from recent developments regarding the contextual nature of personality (e.g., D. Wood & B. W. Roberts, 2006 ), we conducted 2 studies (1 cross-sectional and 1 longitudinal over 1 year) to examine the validity of work personality in predicting job satisfaction and its mediation of the effect of global personality on job satisfaction. Study 1 showed that (a) individuals vary systematically in their personality between roles— they were significantly more conscientious and open to experience and less extraverted at work compared to at home; (b) work personality was a better predictor of job satisfaction than both global personality and home personality; and (c) work personality demonstrated incremental validity above and beyond the other two personality measures. Study 2 further showed that each of the work personality dimensions fully mediated the association between its corresponding global personality trait and job satisfaction. Evidence for the discriminant validity of the findings is also presented.     

Inez Beverly Prosser and the education of African Americans

Inez Beverly Prosser (ca. 1895-1934) was arguably the first African American woman to earn a doctorate in psychology. Her dissertation, completed in 1933, examined personality differences in black children attending either voluntarily segregated or integrated schools and concluded that black children were better served in segregated schools. This research was one of several studies in the 1920s and 1930s that was part of the debate on segregated schools as maintained in the United States under the "separate but equal" doctrine of Plessy v. Ferguson (1896). This article examines the life and career of Prosser in the context of educational barriers and opportunities for African Americans in the early part of the twentieth century and explores the arguments that pitted African Americans against one another in determining how best to educate black children, arguments that eventually led to the desegregation decision of Brown v. Board of Education (1954).     

The Power of Persuasion: Lessons in Personal Selling from the White House

Those Presidents who historians agree have been most successful have been able to sell themselves and their programs to many different constituencies. They have recognized that effective leadership requires many of the same skills as effective personal selling. The experiences of those who have worked in the Oval Office underscore some of the simple but often forgotten lessons of personal selling, and this article catalogs some of the most important of these.
