Aging Performance

Aging behaviours differ in females and males. Females are weaker but survive longer. We report gender decay of skeletal muscle performance by comparing World Records of Master athletes. Master athletes compete in age groups of 5 years till 100 years. The Master World Records are lists of 16 data that, after normalization, show trends of aging decline of muscle performance indicating only minimal gender differences in the process. All trend-lines tend to zero at about 110 years. Since hormons poorly influence aging performance decay, other fundamental bioregulators, e.g., those of cell energy metabolism, seems to be relevant.

Background and Aim: Major depression in both women and men is a debilitating disorder that disrupts relationship and daily lives and affects nearly 10% of general populations. The aims and objectives of this study were to determine the gender differences in major depression with respect to following: Demographic characteristics, Clinical manifestations, Stressful life events, Risk factors. Materials and Methods: Total of 100 patients was included in the study. All the included patients meet the criteria for DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) diagnosis of major depression. The included patients were interviewed at the department of Psychiatry, B. J. Medical College & civil hospital Ahmedabad. Based on the Life Events Scale by Holmes and Rahe (1967), its Indian adaptation PSLE (Presumptive stressful life events scale) was done by Gurmeet Singh (1983). The statistical analysis was done by using SPSS IX version. Results: Their ages range from 18 to 70 years. Most of the patients were married, were from urban background, and nuclear family. On Hamilton Depression rating scale when the statistical analysis was done, there was no significant difference between males and females. Men had higher mean life events score than women but this was not statistically significant. In female, there was significant positive correlation between number of life events in one year and severity of depression as well as impact score during one year prior to onset of depression and Hamilton rating scores. Conclusion: Male and female major depression patients did not differ as regards demographic characteristics, except that most women were homemakers and men were employed. Number of stressful life events experienced during 1 year prior to onset of MDD was similar. Early insomnia, middle insomnia and somatic symptoms general were more severely present in female patients.

Allocation Of Time

<p><em>Thesis as one of the requirements to obtain a bachelor degree, ideally it can be completed in one semester, but many students finish the thesis more than the allocated time. This condition is caused by many factors including gender differences, male and female students have many differences especially in the allocation of time to finish a thesis. This research aimed to find out the factors that influence the time needed to finish a thesis and the classification of these factors based on their gender. The factors observed were GPA, gender and competence of the supervisor, types of research used, source of the data  and technique of the data collection. The statistical analysis used was the CHAID method. The result of this study showed that out of 387 male students who have graduated in period I to VI, it was found that the factors which influence them to finish their thesis were GPA. While for female students, out of 1150 data, three factors that influence them were major, sources of data and expertise areas of the main supervisors. Moreover, three characteristics of students who finish thesis longer than 6 months were male students with a GPA less than 3,34, female students from Islamic Education/English Department/Math Department  with the source primary/ secondary data or others, and female students from guidance and couceling department by the psychologist’s/ others as main supervisor.</em><em></em></p><p align="left"><strong><em>Keywords:</em></strong><em> </em><em>thesis, allocated time to finish thesis, </em><em> </em><em>CHAID method.</em></p>

The objective of this study was to find out whether there are gender differences regarding socio-demographic characteristics and associated risk factors in adults monitored in an outpatient hypertension facility. Retrospective analysis of records of patients seen at the outpatient hypertension clinic in 2009-2010, in a hospital specialized in cardiology, in southern Brazil. All patients were beneficiaries from the Brazilian Unified Healthcare System (SUS). The variables considered were socio-demographic profile, anthropometric measurements and risk factors for hypertension. For statistical analysis, a significance level of 5% (p ≤ 0.05) was adopted. Of the 209 patient records assessed, most belonged to female patients (66%), 65.9% of them were married, 71.6% were white, with mean age 53.5 ± 13.8 years, and 70.1% had a sedentary behavior. Regarding risk factors, waist circumference and alcohol use were higher among men (p=0.04). It was concluded that there was no gender difference concerning the assessed variables, except for the use of alcohol.

Aging behaviours are significantly different in females and males, e.g., the former have a longer life expectancy, but consistently a weaker muscle force. Our purpose is to analyse possible gender-differential declines of skeletal muscle performance. The method to find out the decline of performances with aging is based on a parametric analysis of the World Records of Master athletes in different Track and Field events. The analysis is a transformation (normalization) of sports results into dimensionless parameters ranging from the maximum value of 1 (for the absolute world record) to decreasing values with decreasing performances. Master athletes compete in age groups of 5 years till the age of 100 years, thus their World Records are lists of up to 16 data. Results of the normalization procedure are trend-lines indicating that the decline starts not later than the age of thirty years for both women and women. The decline with aging of the muscle performances indicates only minor gender differences in the aging process and all trend-lines tend to zero at about the age of 110 years. The approach, making use of a homogeneous cohort of testers, gets rid of the main confounding factors biasing other kind of studies of the muscle performance decline with aging, in particular clinical studies. Comparing normalized female and male World Records of Master athletes, a surprise emerged: aging decline is very similar, if not identical, the unique exception to the general rule of gender differences in sports activities. The substantial identity of decline trends among females and males suggests that neuro-hormonal differences among genders poorly influence the aging decline, being conceivably related to fundamental cell bioregulators, such as those of cellular energy metabolism and/or their epigenetic regulatory mechanisms.

Research in the field of emotions has highlighted that men and women differ as regards the perception and reaction to disgust. The aim of our study was to analyse, by means of a questionnaire on disgust, any gender differences regarding this feeling in its various dimensions, viewed both individually and globally. For this purpose a synthetic indicator was developed to evaluate the expression of disgust and identify any individual differences. The sample of 1587 subjects were given a questionnaire on disgust that contained items to elicit disgust. Statistical analysis was performed on the items and on the scores via a synthetic indicator, the Synthetic Disgust Index (SDI).The analysis revealed a different trend in different types of disgust for age and sex. In males. The oral disgust and contamination showed a reduction of SDI in the age group between 18 and 39 years (p<0.05) and a maximum score in the group of subjects 40-64 years. In females the maximum score was present in the first group (0-17 ) for all dimensions of disgust except for disgust for aggressive content (p<0.05). The oral disgust and contamination showed a reduction of SDI in the age group between 18 and 39 years (p<0.05) with a general tendency to decrease with age.

Introduction: Orthodontists have relied on cephalometric radiographs for orthodontic diagnosis and treatment planning since the advent of cephalometric radiography. The variations in different ethnic groups within the same country creates a need for cephalometric norms for each of such ethnic groups. McNamara’s analysis is the most commonly used and most suitable for diagnosis and treatment planning. Aim: The study aims to formulate cephalometric norms for Gujarati boys and girls using McNamara’s analysis. Materials & Method: The sample of children for the study was selected from the government funded primary schools of Gujarat. The sample size consisted of 250 school going Gujarati children (125 boys and 125 girls) with age ranging from 9 to 12 years. Materials & Method: A digital lateral cephalograph was taken under standard conditions for all children and manual tracings were done for identifying all cephalometric landmarks. The analysis was done using McNamara’s analysis and statistical analysis was done Statistical Analysis: Gender differences were calculated using student’s t test. The software was utilized to calculate the mean value, standard deviation, range, maximum and minimum values for all parameters of McNamara’s analysis for Gujarati boys as well as girls. The inter examiner variability was tested using Karl Pearson correlation test. Results: The mean and standard deviation with minimum values, maximum values and range for each of 11 parameters were calculated for all male and female subjects. The gender differences were also calculated for all subjects. Conclusion: This study introduces cephalometric norms for the mixed dentition period using McNamara Analysis for Gujarati children residing in Ahmedabad – Gandhinagar districts of Gujarat which can be utilized for orthodontic treatment in the future.

Marvel superhero movies have a wide audience. Many of these movies contain romance, and therefore it may be valuable to analyze the content of this romance, given its success and influence. This led to the question: Are there differences in expression of romantic ideals and challenges between men and women in Marvel superhero movies? This study addressed this question by performing a content analysis of 23 Marvel superhero movies from Iron Man to Spider-Man: Far From Home. Gender differences were assessed on the frequency of romantic ideals expressed and on the frequency of challenges expressed. Statistical analysis showed there was a significant difference in frequency of romantic ideal expression between men and women. There was no significant difference in frequency of challenges between men and women. There is not a current body of literature that examines gender differences in expression of romantic ideals and challenges between men and women in Marvel superhero movies, and therefore this study can contribute to the current body of work. Implications of the current analysis and suggestions for future investigation are discussed.
