Characteristics of on Organizational Environment which Stimulate and Inhibit Creativity*

The study investigated the characteristics of Brazilian organizations which affect creativity. A sample of 25 workers were interviewed. The respondents answered several questions about the characteristics of a work environment which promote and inhibit creativity, and about factors in their own work environment that contribute to the promotion or inhibition of creativity. Content analysis of the transcribed interviews indicated 10 categories of stimulants and 11 categories of obstacles to creativity. Among the most mentioned stimulant factors to creativity were organization support, organization structure, support from the boss, and colleagues' support. On the other hand, some of the most prevalent obstacles to creativity were organization structure, boss characteristics, personal relationships, and organization culture. Results are discussed in terms of the similarity with data obtained in other contexts.     

The Effect of Selective Serotonin Releasing Agents in the Chronic Mild Stress Model of Depression in Rats

Chronic exposure to mild unpredictable stress has been found to depress the consumption of, and preference for, highly palatable sucrose solution in rats. Stress-induced behavioral deficits may be maintained for a long time, however chronic administration of clinically effective antidepressants can restore normal behavior. This is the first report showing that Sprague-Dawley rats can be used in this model. A preference deficit in this strain of rats took at least 7 weeks to develop; about twice the time required when hooded Lister or Wistar rats are used in this model. Water consumption was not effected by chronic exposure to the mild stress regime and/or by chronic administration of the selective serotonin (5-HT) releasing agent MMAI (5-methoxy-6-methyl-2-aminoindan). The stress-induced deficit in sucrose intake was completely reversed by chronic treatment with MMAI (5 mg/kg, 2 x day) over 3 weeks in the two-bottle tests. In single-bottle tests, chronic treatment with the selective 5-HT releasers, MMAI (5 mg/kg, 2 x day) or MTA (p-methylthioamphetamine; 5 mg/kg, 2 x day), reversed the deficit in rewarded behavior (anhedonia) measured as a decrease in the consumption of 1% sucrose solution in the chronic mild stress model of depression in rats. With the experimental procedure employed, and at a dose of 10 mg/kg/day of 5-HT releasers, the magnitude and onset of this effect were greater than observed following similar administration of the selective 5-HT reuptake inhibitor (SSRI) sertraline (10 mg/kg/day), used as a standard anti-depressant drug.     

INTRODUCTION: GLOBAL DEMOCRACY AND EXCLUSION

Abstract: Does democracy or popular sovereignty imply exclusion and drawing borders? And if so, what type of exclusion and borders, and what kind of justification can we give for them? Moreover, if democracy really requires some kind of exclusion, is global democracy then a paradoxical union of two contradictory ideals? Can we create a demos on the global level? The focus of this collection of essays is on this potential conflict and its underlying values.     

Machiavellian flexibility in negative mate retention

Among the Dark Triad traits (psychopathy, narcissism, and Machiavellianism), Machiavellianism is uniquely associated with flexibility. This flexibility should result in the use of aggressive short‐term tactics only when they do not interfere with long‐term goals. Study 1 found that individuals high in Machiavellianism differed from those high in psychopathy with respect to retrospective accounts of negative mate retention tactics. Study 2 found an interaction between Machiavellianism and relationship type such that individuals high in Machiavellianism tempered the use of negative tactics for long‐term (but not short‐term) relationships. The findings highlight the flexibility of the Machiavellianism construct and its relevance to mating strategies among the Dark Triad.     

A Cross Cultural Examination of Creative Problem Solving Style: The Dutch Translation of VIEW

Creativity and Creative Problem Solving are globally important. This study examined the cross‐cultural applicability of creative problem solving styles by translating VIEW: An Assessment of Problem Solving Style from its native English into Dutch and examining its psychometric properties and preliminary validation evidence. In general, support was found for the Dutch translation of VIEW in that it performed similarly to its original with regard to item performance on factor analysis, had acceptable levels of internal consistency and stability over time, and correlated in a similar manner with two alternative measures of style. Implications for future translations were identified.     

Science as Structured Imagination

This paper offers an analysis of scientific creativity based on theoretical models and experimental results of the cognitive sciences. Its core idea is that scientific creativity — like other forms of creativity — is structured and constrained by prior ontological expectations. Analogies provide scientists with a powerful epistemic tool to overcome these constraints. While current research on analogies in scientific understanding focuses on near analogies, where target and source domain are close, we argue that distant analogies — where target and source domain differ widely — are especially useful in periods of intense conceptual change. To argue this point, we discuss three case studies from the history of science: early physiologists like Harvey, early evolutionary biologists like Darwin, and recent theorists on the evolution of the human mind like Mithen.
