Multidimensional Behaviour

Laboratory experimentation was once considered impossible or irrelevant in economics. Recently, however, economic science has gone through a real ‘laboratory revolution’, and experimental economics is now a most lively subfield of the discipline. This study attempts to examine answers to questions of the changing behaviour of opposite sexes under conditions of both anonymity and knowledge of gender by playing the ultimatum game in Pakistan. It is observed that the behaviour of males and females in Pakistani society is quite different from that found in earlier studies. Insights from the previous experiments have already shown that normative economic theory had failed in its predictions of human behaviour. Currently, the ultimatum game is widely discussed in behavioural economic literature, and this paper will adjust the traditional ultimatum game into a new form wherein it will be tested in the country (Pakistan) with multidimensional behaviour of subjects. With regard to gender effect specifically, all previous studies came up with somewhat mixed results, since results do not always point in the same direction and it is rather early to draw far-reaching conclusions regarding the behavioural differences of men and women. More facts are required in order to move towards the development of a systematic theory. This work is a small attempt to investigate the changing behaviour of opposite sexes under different controlled conditions.

And Gender

Females’ performance in a gender-stereotyped domain is impaired when negative gender stereotypes are activated (Nguyen & Ryan, 2008). “Stereotype threat” affects the gender difference in adults’ mental-rotation performance (e.g., Moè & Pazzaglia, 2006). Our study investigated this effect in fourth graders. Two hundred sixteen males and females solved two mental-rotation tests. In between, a gender-difference instruction was given (“boys better,” “girls better,” “no gender difference”). A significant interaction of time and gender was found in the “girls better”-condition and in the “no gender difference”-condition: As expected, the male performance advantage disappeared after these two instructions, because girls improved and boys deteriorated. Thus, the study suggests that the gender effect in mental rotation is affected by stereotype threat and stereotype lift from the very beginning of its occurrence. Results are discussed within a biopsychosocial framework and seem to play an important role with regard to the “hidden curriculum” in schools.

Probability Of Cancer

Introduction: Computer Tomography (CT) scans can deliver a relatively high radiation dose to the patient, therefore radiation protection for this modality is paramount. The present study determined the frequency of no abnormality detected (NAD) brain CT scans and probability of cancer induction in different age groups and genders. Methods: In this study, brain CT reports were used to identify any findings as abnormality detected (AD) and others as NAD. Then probability of future leukemia and brain cancer was estimated for different age and gender groups. Results: On average, in 65% of the cases the results were NAD (56% and 76% among males and females, respectively). Among children, 79% of the reports were NAD. The total number of projected brain cancers was 1.8 and 1.3 for males and females, respectively. The number of projected leukemia cases was 0.75 and 0.7 for males and females, respectively. For pediatric patients, brain CT scans can lead to leukemia cases about 4.5 times more often than adults. Conclusion: Brain CT scans can lead to additional cases of brain cancer and leukemia. A significant fraction of brain CTs were NAD (non-pathologic) and could practically be replaced by other radiation-free imaging modalities, especially in pediatric and young patients.

ABSTRACTObjectives: The aim of this study is to determine retrospectively the presence of carotid artery calcifications (CACs) detected on panoramic radiographs (PRs) in a group of Turkish population. Further, the relationships between CACs and gender, life style, and medical history were evaluated.Methods:During the years 2004 to 2006, a random sample of 1282 PRs was collected from patients older than 40 years who were being treated by the School of Dentistry, Erciyes University. Of these 1282 PRs, 750 PRs were included in this study. Medical data was collected from the archival records of the dental school.Results: About 38 (5.06%) CACs were found on the PRs of 12 (4.5%) males and 26 (5.4%) females. The CAC prevalence was not significantly different between the males and females (P=0.583). These calcifications were unilateral in 26 (68.4%) and bilateral in 12 (31.6%) subjects. Of those in the positive group, there were 12 subjects (31.58%) with hyperlipidemia, 12 subjects (31.58%) with hypertension, 7 subjects (18.4%) with diabetes mellitus, 6 subjects (15.8%) with cardiovascular disease, and 6 subjects (15.8%) with smoking history.Conclusions: This study has the highest CACs prevalence in comparison to the other studies. Therefore, dentists caring for subjects with dental problems should carefully evaluate their PRs for the evidence of CACs, and refer them for medical evaluation as indicated. So, incidental findings could provide life-saving information. (Eur J Dent 2007;1:132-138)

Melanotic Encapsulation

A few studies have shown that male and female invertebrates differ in immunity and that these differences appear related to differences in sexual dimorphism and gender differences in life histories. Melanotic encapsulation of foreign objects in insects is one form of immunity. The damselfly Lestes forcipatus Rambur is moderately sexually dimorphic, and much is known about patterns of mass gain in congeners relating to differences in life history between males and females. In this study, females were more immunoresponsive than males under controlled temperatures, following emergence, and at a time when parasitic mites were challenging these hosts. However, males and females that overlapped in mass at emergence did not differ in their immune responses. Males in better condition at emergence were more immunoresponsive than lighter males, but this relation was not found in females. Sex differences in immune expression may have implications for how females versus males are able to deal with challenges from parasites, under varying environmental conditions.

This study uses data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) project to assess the relationships between childhood physical abuse/sexual abuse and adolescent substance use. Whether these relationships are mediated by externalizing problems, internalizing problems, parent–child attachment, or anger and gender differences in these direct and indirect relationships is also addressed. Results indicate that there is a direct relationship between physical abuse and substance use and that mediating pathways between maltreatment and substance use are different for males and females. These results suggest that gender-responsive services should be provided to prevent and address adolescent substance use.

The Relationship

The Psychological Skills Inventory for Sport (PSIS; Mahoney, 1988) identifies certain psychological skills or characteristics possessed by successful athletes. However, little has been done to connect the PSIS with other variables that may have an impact on the athletes’ psychological skills. Therefore the purpose of this study was twofold. First, the psychometric properties of the PSIS for all subjects and by gender were determined. Second, the relationship between the PSIS, experience, practice commitment, and gender of collegiate skiers was examined. A random sample of 131 male and female collegiate skiers responded to the 45-item PSIS. Overall, the six PSIS subscales (anxiety, concentration, confidence, mental preparation, motivation, and team emphasis) demonstrated acceptable internal reliability (coeff. alpha = .69−.84). Results of a 4 × 3 × 2 (Experience × Practice Commitment × Gender) MANOVA and follow-up univariate F tests revealed a significant gender effect on the team emphasis subscale. Female collegiate skiers were more team oriented than male collegiate skiers and placed more importance on the social and affiliative aspects of being on a team than did their male counterparts.

The aim of this study was to reveal and to describe the structure of the verbalized concept of «flirting». The main method of the research was a psycholinguistic experiment. The sample comprised 400 young people (aged 18-35), males and females being equally represented. The concept of «flirting» is represented by eleven clusters, four of them are core: «verbal and non-verbal ways of communication», «forms and ways of interaction», «emotions, feelings, states», and «gender». Two psycholinguistic meanings of «flirting» concept were described: «The stage of courtship with no intimate relation», «Sexual relationship». The semantic content of the concept of «flirting» does not depend on gender identification. The general attitude of the respondents to the stimulus «lightness» is quite positive.
