Physician Involvement in Torture: An Ethical Perspective

Evidence proves that physician involvement in torture is widely practiced in society. Despite its status as an illegal act as established by multiple international organizations, mandates are routinely unheeded and feebly enforced. Philosophies condemning and condoning torture are examined as well as physicians’ professional responsibilities and the manner in which such varying allegiances can be persuasive. Physician involvement in torture has proven detrimental to the core values of medicine and has tainted the field’s commitment to individuals’ health and well-being. Only when this complex issue is addressed using a multilevel approach will the moral rehabilitation of medicine begin.

Dimensions of the Turkish version of the Psychological Empowerment Scale

The purpose of the present study was to examine the dimensions of Spreitzer's Psychological Empowerment Scale for Turkish-speaking people. The scale was tested with a group of undergraduate students in Turkey (N = 214; M age = 22.6 yr., SD = 1.5, range = 19-27). Cronbach coefficient alpha was .84. By using maximum likelihood analysis with oblique rotation, three factors emerged and were labeled Influence, Meaning, and Competence.     

A new driver behavior model to create realistic urban traffic environment

This paper presents a new driver behavior model, which emulates various driving styles (i.e. behaviors) for different categories of drivers. The model was highly parametric and was developed based on a two-layer Hierarchical Concurrent State Machines (HCSM) programming framework. Our study has been specifically oriented to create a realistic urban traffic environment with hazardous situations typical of real life in a driving simulator, and let the novice drivers to practice in a safe environment. In our study, we used TRAFIKENT driving simulator as a test-bed. Experiments and evaluations demonstrated satisfactory results in terms of behavioral validity of our model.     

An Early History of Multiple Criteria Decision Making

This historical note is based on a plenary talk ‘A History of Early Developments in Multiple Criteria Decision Making’, presented by Stanley Zionts at the 21st International Conference on Multiple Criteria Decision Making held in Jyväskylä, Finland, June 2011. It draws heavily on our book, Multiple Criteria Decision Making: From Early History to the 21st Century, published by World Scientific, Singapore, 2011. Copyright © 2013 John Wiley & Sons, Ltd.     

Associations between procrastination,personality, perfectionism,self-esteem and locus of control

To date, many variables but particularly trait-like psychological constructs have been found to strongly contribute to procrastination but the complex relations among these variables collectively have received almost no attention. The purpose of the study was to provide a more profound understanding of the relations between procrastination, perfectionism, big five personality, locus of control and self-esteem. Young adults (162 women, 80 men: M?=?20.98) completed measures of academic procrastination, self-esteem, big five personality, perfectionism and locus of control. Parental criticism was a significant correlate of procrastination, while personality traits of conscientiousness, agreeableness and organisation were inversely associated with procrastination behaviour. These findings suggest that personality-based intervention approaches with the inclusion of family can be more influential in procrastination prevention and treatment.     

Cognitive control of a simple mental image in patients with obsessive--compulsive disorder

The nature of obsessions has led researchers to try to determine if the main problem in obsessive-compulsive disorder (OCD) is impaired inhibitory control. Previous studies report that the effort to suppress is one of the factors that increase the frequency of obsessive thoughts. Based on these results and those of the present study that suggest inferior parietal lobe (IPL) abnormality in OCD and findings of a recent study that reported the importance of the right posterior parietal cortex in cognitive control of a simple mental image, the present cognitive control paradigm study aimed to determine whether there is a difference in brain dynamics between OCD patients and non-obsessive controls while performing tasks that necessitate cognitive control of a simple mental image, and whether the right posterior parietal region is one of the regions in which a difference in activity between the OCD patients and controls would be observed. Functional brain imaging was performed while the participants attempted to suppress, imagine, or manipulate a mental image. The general linear model showed that there was a main effect of group and main effect of task. Accordingly, in all contrasts (suppression minus free-imagination, erasing minus free-imagination, and imagination minus free-imagination), the right IPL, right posterior cingulate cortex, and right superior frontal gyrus activity were lower in the OCD patients than in the healthy controls. These results and the observed correlations between activity levels, and symptom and subjective performance scores are discussed. In conclusion, the results of the present study and those of previous studies suggest that the main problem in OCD might be difficulty activating the right frontoparietal networks during tasks that require cognitive control, which might result in the intrusiveness of obsessive thoughts.
