Social Safeness and Psychological Vulnerability in Turkish Youth: The Mediating Role of Life Satisfaction

The present study examined whether life satisfaction mediated social safeness and psychological vulnerability in Turkish youth. The participants included 261 university students who completed a questionnaire package that included the Turkish versions of the Social Safeness and Pleasure Scale, the Satisfaction with Life Scale, and the Psychological Vulnerability Scale. To test the proposed mediation model, authors employed hierarchical regressions. Furthermore, the authors tested mediation model using the Sobel Z-test and bootstrapping method to examine any indirect effects. Consistent with our hypotheses, the results indicated that there was a positive relationship between social safeness and life satisfaction, and a negative relationship between social safeness and psychological vulnerability. The results of the Sobel Z-test and bootstrapping revealed that life satisfaction significantly, yet partially, mediated the relationship between social safeness and psychological vulnerability. The findings highlight the importance of life satisfaction in enhancing perceptions of social safeness and decreasing psychological vulnerability among Turkish college students.     

A Research Note on the Incremental Validity of Job Knowledge and Integrity Tests for Predicting Maximal Performance

In a sample of industrial job applicants, relationships among scores on an integrity test, a job knowledge measure, and maximal performance as assessed by a work sample measure were investigated. The observed correlation between the personality-based integrity test and maximal performance was .27, indicating that integrity tests can be predictive of maximal performance. Furthermore, integrity test scores correlated .14 with job knowledge and job knowledge scores had a validity of .36 for maximal performance. Theoretical implications for the maximal/typical performance distinction are discussed.     

Understanding the Effects of Cognition in Creative Decision Making: A Creativity Model for Enhancing the Design Studio Process

ABSTRACT

The essential components of creativity—persons, processes and products—were investigated inside a creative environment by deeply focusing on the cognitive stages of the creative decision making process. Mental imagery and external representation were considered as the implicit parts of creativity for enhancing design studio process. An experiment was conducted with 15 subjects who designed the public area of a train as the task in design studio. Observation, protocol analysis, and rating scales were used as assessment tools. Considering the components of creativity, it was found that the highest correlation was between process and overall creativity. Person and product followed process, respectively. However, no significant relationship was observed between imagery and creativity in design process. Three-dimensional representations were found to lead to more creativity compared to 2-dimensional depictions.     

Age,Emotion Regulation Strategies,Temperament, Creative Drama,and Preschoolers' Creativity

Based on Yeh's (2004) Ecological Systems Model of Creativity Development, this study investigated the effects that age, the use of emotion regulation strategies, temperament, and exposure to creative drama instruction have on the development of creativity among preschool children. Participants were 1164‐ to 6‐year‐old preschool children. This study categorized the emotion regulation strategies used by preschool children and developed a creativity test which includes the measurement of usefulness, an indicator of creativity that has, until now, been ignored. The main findings are that (a) 6‐year‐olds outperform 4‐ and 5‐year‐olds in terms of creativity; (b) emotion regulation strategies as well as a positive temperament have positive effects on children's creativity; (c) creative drama instruction contributes to children's creativity; and (d) age group, emotion regulation strategies, temperament, and creative drama instruction can collectively predict children's creativity.     

Methods of punishment used by Turkish mothers of preschoolers

The goal of this study was to describe the punishments that Turkish mothers use with their preschool-aged children. 129 mothers with children between 3 and 6 years old were included in the study. Mothers completed a data collection form prepared by the researcher. Punishments mothers applied and mothers' age and education and children's age and sex were examined by chi-squared analysis. Mothers used various punishments with children. Some punishments were used with high frequency. Mothers' age and education and children's age and sex were not related to types of punishment used.     

Viral vector mediated overexpression of human alpha-synuclein in the nigrostriatal dopaminergic neurons: a new model for Parkinson's disease

Parkinson's disease is predominantly a dopamine deficiency syndrome, which is produced in the brain by the loss of cells located in a small area in the ventral midbrain called the substantia nigra. Complete unilateral dopamine lesions, based on the administration of toxic substances (ie, 6-hydroxy-dopamine in rats and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine in mice and primates) have been extremely useful in testing strategies of replacement. For example, the functional and biochemical impact of the transplanted ventral mesencephalic dopaminergic progenitors has been characterized to a large extent, using the complete lesion model in rats. Over the last decade, however, studies addressing the ability of neurotrophic factors to protect injured dopamine cells prompted researchers to make available partial and progressive lesion models to allow a window of opportunity to interfere the disease progression. Recent findings relating alpha-synuclein with Parkinson's disease pathology have opened new possibilities to develop alternative models based on the overexpression of this protein using recombinant adeno-associated viral vectors, which is valuable not only for helping to better understand its involvement in the disease process, but also to more closely resemble the neurodegeneration found in Parkinson's disease.
