Body image satisfaction and anxiety of a Turkish sample of university students with skin diseases

The aim of this study was to evaluate perception of body image and anxiety of 221 university students presenting to the dermatology outpatient clinic with a skin disease and 205 students without skin disease. Analysis of anxiety and body image scores yielded differences by sex and age in both groups. The group with skin disease had lower scores on body image. Acne vulgaris seems to be the most disturbing among the skin diseases, and this was more prominent in younger patients.     

The influence of language and socioeconomic status on children's understanding of false belief

Study 1 investigated whether differences in the lexical explicitness with which languages express false belief influence children's performance on standard false belief tasks. Preschoolers speaking languages with explicit terms (Turkish and Puerto Rican Spanish) were compared with preschoolers speaking languages without explicit terms (Brazilian Portuguese and English) on questions assessing false belief understanding either specifically (the think question) or more generally (the look for question). Lexical explicitness influenced responses to the think question only. Study 2 replicated Study 1 with groups of both speakers differing in socioeconomic status (SES). A local effect of explicitness was found again as well as a more general influence of SES. The findings are discussed with regard to possible relations among language, SES, and understanding of mind.     

Relations among hand preference,craniofacial asymmetry,and ear advantage in young subjects

The relations for hand preference with craniofacial asymmetry and ear advantage, and between craniofacial asymmetry and ear advantage were investigated in young healthy subjects. Ear advantage was recorded as duration of hearing, craniofacial asymmetry by computerized tomography in 44 right-handed and 38 left-handed male and female high school students. Right-handers had a right ear advantage and a larger left craniofacial region, whereas left-handers had a left ear advantage and a larger right craniofacial region. These results are consistent with the speculation that hand preference may be related to craniofacial and consequently aural asymmetries.     

Personality or Role? Comparisons of Turkish Leaders Across Different Institutional Positions

Personality approaches to politics are often criticized for not examining the effect that institutional role constraints have on individual beliefs and preferences. When leaders appear to change their stance when they change roles, it is assumed that roles have a determining influence. Modern personality theory and contemporary sociological role theory, however, view the effects of roles as interacting with agents’ personalities. In this article, we investigate this question by comparing personality profiles of three Turkish leaders (Özal, Demirel, and Gül) during their tenure as prime minister and during their subsequent time as president. For Gül, we perform an additional comparison during his time as foreign minister. The personality profiles are in the form of quantitative scores generated from machine‐coded content analysis of leaders’ words using the Leadership Trait Analysis method. We hypothesize that different leaders will be more susceptible to changing role contexts, depending on core personality traits, and that different traits are more likely to change with new roles. Overall, our results suggest that leaders’ traits are fairly resistant to changes across roles and that task orientation is the most likely trait to change as leaders adapt to different role demands and expectations. This study makes a contribution to our understanding of the interaction between personality and political contexts by offering specific theoretically derived hypotheses and by empirically and statistically examining a preliminary set of expectations that could be applied more broadly to other leaders.     

Farewell to the world: suicide notes from Turkey

There has been limited study of suicide in Islamic countries. This paper marks the first study of suicide notes in Turkey, an Islamic country. Using a classification scheme, 49 suicide notes (a rate of 34.5%) were studied. The results show that note writers do not differ greatly from other suicides. Further analysis of younger (<40) and older (>40) suicide note writers reveal few significant differences. Our results, together with the results of classification studies in different countries, suggest that caution is in order in transposing findings from one country to other countries. Future study of suicide notes should, in fact, focus on cross-cultural investigation.     

Incidence of depression related to isotretinoin treatment in 100 acne vulgaris patients

The incidence of depression in acne patients using isotretinoin was assessed in 100 patients with moderate and nodulocystic acne. All patients received 0.75-1.00 mg/kg/day of isotretinoin for 20-28 weeks after acne was assessed. All patients' acne lesions were improved at the end of the treatment period. Psychological state was evaluated at baseline, at Month 3, and Month 6 by a psychiatrist using a Turkish version of the Hamilton Depression Rating Scale. Only one patient's score increased to the clinical level of depression at Month 3 of treatment and declined to subclinical levels at Month 6. Although Hamilton scores increased at Month 3 over baseline scores, except for one patient, others' scores remained below the subclinical level for depression. At the end of Month 6, the mean score decreased below that at Month 3. These changes in means might be related to the onset of clinical effect of isotretinoin.     

A Developing Approach to Studying Students’ Learning through Their Mathematical Activity

We discuss an emerging program of research on a particular aspect of mathematics learning, students’ learning through their own mathematical activity as they engage in particular mathematical tasks. Prior research in mathematics education has characterized learning trajectories of students by specifying a series of conceptual steps through which students pass in the context of particular instructional approaches or learning environments. Generally missing from the literature is research that examines the process by which students progress from one of these conceptual steps to a subsequent one. We provide a conceptualization of a program of research designed to elucidate students’ learning processes and describe an emerging methodology for this work. We present data and analysis from an initial teaching experiment that illustrates the methodology and demonstrates the learning that can be fostered using the approach, the data that can be generated, and the analyses that can be done. The approach involves the use of a carefully designed sequence of mathematical tasks intended to promote particular activity that is expected to result in a new concept. Through analysis of students’ activity in the context of the task sequence, accounts of students’ learning processes are developed. Ultimately a large set of such accounts would allow for a cross-account analysis aimed at articulating mechanisms of learning.
