World Records

The differences between male and female performance in athletic track events at which both compete are compared. It is found that the difference between male and female performance as measured by world records is declining in all events and declining most rapidly in those events in which the differences at the present time are largest. Analysis of national track records for these same events shows considerable differences between different countries in average male/female differentials and the differences between males and females for some events in some countries is much smaller than world record differences.It is concluded that social factors such as differing degrees of encouragement and differing levels of expectation are important factors in limiting female athletic performance.

Competition For Resources

Selection to obtain mating opportunities is hypothesized to be a major factor in dispersal. Thus, if individuals move to another group or switch nests to maximize their reproductive opportunities, they should move to groups or sites where they minimize competition for resources or mates and where they can find potential mates. We examined movement of pine voles (Microtus pinetorum) in an orchard habitat. Males dispersed later than females, but the two sexes showed similar patterns of movement with respect to conspecifics. Males and females immigrated to territories that contained some opposite-sex conspecifics; they also immigrated to territories without same-sex conspecifics. The latter suggests that they may avoid competitors and move to territories where an opening exists. When female breeders were removed from a social group, a replacement female arrived and began to breed relatively rapidly. In control groups where breeding females were not removed, no replacement females appeared. These results suggest that pine voles, at least females, may monitor vacancies and immigrate if a vacancy appears.

Relative to the general population, Native Americans (NA) bear a disproportionate burden of suicide-related mortality rates. NA males and females aged 15 to 24 years experience suicide rates nearly 3 times than the U.S. all races rates in this age group. Although efforts have been made to understand and reduce suicide in tribal communities, a large portion has focused on individual characteristics with less attention given to social factors that may also inform suicide. This article aims to build on a local conceptual model of NA youth suicide by examining additional potential social factors through qualitative interviews. Findings from the thematic analysis resulted in the identification of seven perceived social influences: contagion, violence and abuse, discrimination and bullying, negative expectations, spirituality, social support, and cultural strengths. Public health approaches to reduce suicide should consider local social factors that resonate with tribal communities to build resilience.

The objective of this study was to test the reactions of domestic guinea pigs to the presence of aerial and terrestrial predators in a laboratory setting. We measured the behavioural reactions of 27 adolescent guinea pigs to the presence of a dog, imitation of a bird of prey and an unknown human as control. Kruskal-Wallis ANOVA and Mann-Whitney U Test were used to analyse the differences in duration and frequency of responses (freezing, fleeing, and vigilance) to predators. When confronted with the dog, guinea pigs reacted for the longest time and most frequently by freezing. In presence of the bird of prey, they responded for the longest time and most often by freezing and fleeing. In presence of a human, they showed mostly vigilance. When comparing reactions to the dog and human, there were differences in duration and frequency of freezing and fleeing. When comparing reactions to the bird of prey and control test, we observed differences between fleeing and vigilance. The durations and frequencies of freezing, fleeing and vigilance to the dog and bird of prey were different. The only differences in reactions of males and females occurred in duration and frequency of fleeing in presence of the bird of prey. No vocalization was observed except for two occurrences, of a “drrr” and a “chirrup”. Our results indicate that domestic guinea pigs tested under laboratory conditions can discriminate between a terrestrial and an aerial predator, when exposed to them individually. Their antipredator behaviours remained functional, although their vocalizations may have been affected by the absence of signal receivers.

Eurycea Nana

AbstractSocial interactions of conspecifics are a function of complex relationships involving resource defense, antipredatory tactics, and mate acquisition. Consequently, individuals often associate non-randomly with conspecifics in their habitats, with spatial distributions of adults ranging from territorial spacing to aggregations. Site tenacity and cohabitation patterns have been well studied in many species of terrestrial salamander; however, less is understood about these behaviors in aquatic species. We examined the cohabitation patterns of intrasexual and intersexual pairs of the federally threatened, paedomorphic San Marcos salamander (Eurycea nana) under artificial shelters in a laboratory setting over a 20-day period. We found that intrasexual female pairs and intersexual pairs were found cohabiting more often than intrasexual male pairs. We also assessed site tenacity by examining shelter affinity and found that both males and females inhabited one of the two shelters more often than expected from random habitation, regardless of whether they were in intersexual or intrasexual pairings. Our results indicate that although both sexes of Eurycea nana exhibit site affinity, the sex of individuals is an important determinant of cohabitation patterns.

Ultrastructural Findings

Ultrastructural defects of ciliary structure have been known to cause recurrent sino-respiratory infection concurrent with Kartagener's syndrome. (1,2,3) These defects are also known to cause infertility in both males and females. (4) Overall, the defects are defined as the Immotile, or Dyskinetic Cilia Syndrome (DCS). Several ultrastructural findings have been described, including decreased number of cilia, multidirection orientation, fused and compound cilia, membrane blebs, excess matrix in the axoneme, missing outer tubular doublets, translocated doublets, defective radial spokes and dynein arms. A rare but noteworthy ultrastructural finding in DCS is the predominance of microvilli-like structures on the luminal surface of the respiratory epithelium. (5,6) These permanent surface modifications of the apical respiratory epithelium no longer resemble cilia but reflect the ultrastructure of stereocilia, similar to that found in the epidydimal epithelium. Like microvilli, stereocilia are devoid of microtubular ultrastructure in comparison with true cilia.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.

Prior studies have proven the existence of the "hearing aid effect" when photographs of Caucasian males and females wearing a body aid, a post-auricular aid (behind-the-ear), or no hearing aid were judged by lay persons and professionals. This study was performed to determine if African American and Caucasian males, judged by female members of their own race, were likely to be judged in a similar manner on the basis of appearance, personality, assertiveness, and achievement. Sixty female undergraduate education majors (30 African American; 30 Caucasian) used a semantic differential scale to rate slides of preteen African American and Caucasian males, with and without hearing aids. The results of this study showed that female African American and Caucasian judges rated males of their respective races differently. The hearing aid effect was predominant among the Caucasian judges across the dimensions of appearance, personality, assertiveness, and achievement. In contrast, the African American judges only exhibited a hearing aid effect on the appearance dimension.
