Purpose: To analyze the pacing profiles of the world’s top 800-m annual performances between 2010 and 2016, comparing men’s and women’s strategies. Methods: A total of 142 performances were characterized for overall race times and 0-to-200-m, 200-to-400-m, 400-to-600-m, and 600-to-800-m split times using available footage from YouTube. Only the best annual performance for each athlete was considered. Overall race and split speed were calculated so that each lap speed could be expressed as a percentage of the mean race speed. Results: The mean speed of the men’s 800-m was 7.73 (0.06) m·s−1, with the 0-to-200-m split faster than the others. After the first split, the speed decreased significantly during the 3 subsequent splits (P < .001). The mean speed of the women’s 800-m was 6.77 (0.05) m·s−1, with a significative variation in speed during the race (P < .001). The first split was faster than the others (P < .001). During the rest of the race, speed was almost constant, and no difference was observed between the other splits. Comparison between men and women revealed that there was an interaction between split and gender (P < .001), showing a different pacing behavior in 800-m competitions. Conclusions: The world’s best 800-m performances revealed an important difference in the pacing profile between men and women. Tactics could play a greater role in this difference, but physiological and behavioral characteristics are likely also important.

Thomas Aquinas offers for his time a novel take on human sexual difference, in that he grounds human sexuality in what we might term a metaphysical biology and accords it a privileged role in the moral life. Though his biology is drawn from Aristotle, which leads Aquinas to make problematic statements on sexual difference, he nonetheless offers a perspective that remains deeply relevant and significant for today. His method or approach of tethering sexual difference first and foremost to our animal-like biological design remains perennial, particularly at a time when many seek to dismiss biology as irrelevant to sexual identity and gender difference. The latest findings of the emerging field of neurobiology, which have uncovered structural differences between the male and female brains, offer key support to Aquinas’s approach. Even more important, he holds, in an unprecedented move, that sexual design and inclination provide a veritable source of moral excellence. He goes so far as to locate the mean of virtue in our sexual design and appetites.

The relative contribution of sex and situation has become a contested issue in the understanding of sex differences in behavior. In the present study, 20 male and 20 female undergraduates were asked to describe their behavior and thoughts in six everyday college situations. Three of the situations were constructed to be typically male and three typically female in content. The results indicate that men and women demonstrate sex-specific characteristics in their responses regardless of the type of situation presented. Men exhibited concern with separateness from others, while women exhibited concern with sustaining connection to others, even when faced with situations described to present demand properties that might be expected specifically to elicit the concern characteristic of the other sex. However, for these students the situation also made a difference: female-defined situations elicited the most masculine responses for both male and female subjects.

Eating behaviour can vary with age, experience, and gender, as well as food hardness. This variation can contribute to intraspecific dietary differences and may result in variable definitions of optimal foraging and decreased intraspecific competition. We quantified feeding behaviour of insectivorous bats eating hard and soft mealworm-based food items based on the bats’ ability to consume and manipulate food items, consumption time, chew frequency, and total chews to consume. Adult Myotis lucifugus (LeConte, 1831) were more successful at both consuming and manipulating mealworms and consumed mealworms more quickly, with greater chew frequency and in fewer chews, than did subadults. Adults chewed mealworm viscera more frequently than did subadults but showed no differences in the other variables. Adult Eptesicus fuscus (Beauvois, 1796) consumed mealworms more quickly and with fewer chews than did subadults but showed no differences in the other variables. There were no differences between adult and subadult E. fuscus when consuming mealworm viscera. Male and female M. lucifugus did not differ significantly when eating either mealworms or mealworm viscera. There was no change in subadult consumption time of mealworms over the summer. Age-based differences in eating abilities may play a role in defining optimal foraging and dietary composition in insectivorous bats.

The flight activity and flight muscle of the melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae) were observed. The Tethered technique was used to observe the flight activity in this study. The flight activity, and wing and flight muscles were compared between male and female melon flies. The results indicate that the female was relatively better and strong flier than the male. The mean duration of the flight activity of the females was 13.90 min/hour and of the males was 7.12 min./hour. The mean length, width, volume of wings of the males were 6.07 mm, 2.67 mm and 10.99 mm³, respectively. On the other hand, the mean length, width and volume of the wings of females were 7.07 mm, 2.87 mm and 15.60 mm³, respectively. In case of wing muscles, the mean volume of dorsal longitudinal muscle (DLM) in male and female was found 5.20 mm³ and 5.67 mm³, respectively. The mean length of flight wing muscle of male and female was 2.22 and 2.23 mm, respectively and the mean breadth of male and female was 1.65 and 1.77 mm, respectively. Dhaka Univ. J. Biol.

And Control

Inspired by sexual scripting theory, this article analyses intimacy and control in prostitution. The authors identify two strategies for maintaining control among male and female sex sellers. The first strategy is to restrict prostitution to relationships with as much sexual reciprocity as possible. The other is to maintain sexual/emotional distance from customers – yet often acting the opposite. The article questions prevailing stereotypes about male sex sellers being more agentic and autonomous than female sex sellers, arguing that control in prostitution can be achieved (and lost) in different ways. The analysis shows how scripting theory – with its differentiation between the cultural, interpersonal and intrapsychic levels of scripting – may be used to understand variations and contradictions in prostitution experiences. The article is based on 36 qualitative interviews with men and women in escort services, clinic prostitution and prostitution in private apartments in Denmark.

Using Riedel and Zahn's 1994 reformatted version of an FBI database, the mean age of homicide victims in 2,175 homicide–suicides (4,350 deaths) was compared with that of all other victims of homicides reported for the USA from 1968 to 1975. The overall mean age of homicide victims in homicide–suicides was 1 yr. greater than for victims of homicides not followed by suicides, whereas the mean age for both male and female homicide–suicide victims was, respectively, 3 yr. less and greater than the other homicide victims. The mean age of Black homicide victims of homicide–suicides was 2.4 yr. less than that for Black victims of other homicides, whereas the means for Black and White male homicide victims in homicide–suicides were, respectively, about 4 and 5 yr. less than for victims of other homicides. Also, the mean age of White female homicide victims in homicide–suicides was more than two years greater than for female victims of homicides not followed by suicides. When both sex and race were considered, the mean age for those killed in homicide–suicides relative to those killed in homicides not followed by suicides may represent subpopulations with different mean ages of victims.

Aim. To evaluate the dynamics of obesity and mean body mass index (BMI) in Russia and USA in various age and gender categories during 1975-2014.Material and methods. By a repeat analysis of one-moment studies of Russian and US population in 1975-1982 and 2007-2014, the values of obesity and BMI were assessed in men and women age 25-64 y. o. Into analysis, the data was included from Russian part of the Lipid Clinics study and multicenter ESSE-RF study (Epidemiology of cardiovascular diseases and risk factors in various regions of Russian Federation). American data acquired from the studies NHANES (National Health And Nutrition Examination Survey), open access. Total number of observations 48974.Results. In the 80s of XX century in all age groups of women the mean BMI levels were lower in USA comparing to Russia, in men there were no significant differences. For the following 30 years in Russia the situation improved for men and women <45 y. o. — differences with USA changed modality, and currently BMI in Russia is lower than in USA.Conclusion. Russia was below the US 30 years ago by the mean BMI in females of all ages, with no differences for males. For the following 30 years in the US there was significant increase of BMI in all age strata of men and women, and in Russia dynamics was the same, but lesser. Comparison of the prevalence of obesity in men 30 years ago showed some predominance of obesity in American males, especially young, but not statistically significant. Russian women had higher prevalence of obesity regardless of age. Currently, obesity in young age is more prevalent in men and women of USA, and >45 years old — in Russia.

Today's women's issues are still very important to pay attention to because women's rights have not been fully fulfilled. The marginalization of women's rights often stems from local religious and cultural beliefs. This is where the importance of the thinking of figures like Asghar Ali Engineer is reviewed in the present. This paper discusses the thoughts of Asghar Ali Engineer about liberation theology in the matter of women's rights in Islam. Asghar Ali Engineer in many of his works has offered various kinds of deconstruction of discourses. In the matter of women's rights in Islam, he presents his opinion on inheritance, wealth, testimony, the position of women in the family, polygamy and divorce which are considered as examples of inequality. With its hermeneutic interpretation, Asghar Engineering rejects the existence of a patriarchal concept that is inherent in the classical interpretation of the Quran, which is considered discriminatory against women. Then he applies the verses of the Quran into two, namely normative and contextual, with the hope that the verses of the Quran can be reinterpreted, so that it truly becomes a universal verses of “das solen” on one side and contextual verses of “das sein” on the other. Thus, the equality of men and women can be realized and gender-based justice can be manifested.

It is readily apparent that many Melanesian societies maintain a distance between men and women. Some ethnographers working in Melanesia have posited reasons for this dichotomy, for example, fear of contamination from menstrual blood, or the importance of male solidarity in social organization. These theories do not adequately explain gender concepts and the range of social interaction between the sexes. By focussing on the belief surrounding male homosexual behaviour in initiation ritual, this paper attempts to demonstrate that gender concepts in Melanesia, like attitudes towards homosexuality, cannot be explained in terms of Western categorizations of male and female, or in terms of Western concepts of sexuality. A comparison of the correlation between homosexuality and gender beliefs among North Americans and among Melanesians indicates that the apparent separation of the sexes in Melanesia is not due to the inherent distinctness of male versus female, as reflected in the Western dichotomies that colour such ethnographic descriptions of gender. It is suggested that in Melanesian societies men must be differentiated from women, and that mutable gender categories must be maintained by social sanctions that delineate the sexes during the reproductive years.
