This study proposed to morphologically analyze the adult human occipital condyle, estimate the bilateral differences, sexual dimorphism and compare with the available data. We conducted this study on hundred occipital condyles in fifty dry human skulls. The measurement was performed by the means of the vernier’s caliper on both sides of the skull. The parameters measured are length, width, heig...

A study of tooth size was carried out on medieval skeletal material from Aebelholt and Naestved in Denmark. Measurements of all suitable permanent teeth were made in both mesiodistal and buccolingual dimensions with a sliding caliper with vernier reading to 0.1 mm. The material was divided according to sex and place of excavation; statistical preparation of the data provided mean values and sta...

Recent applications of social capital theories to population health often draw on classic sociological theories for validation of the protective features of social cohesion and social integration. Durkheim's work on suicide has been cited as evidence that modern life disrupts social cohesion and results in a greater risk of morbidity and mortality-including self-destructive behaviors and suicid...

a r t i c l e i n f o Youth in the foster care system are at greater risk for a host of aversive outcomes including diminished educational performance and attainment. While these issues are well-documented, less is known about gender differences on academic outcomes for these students. Over the past three decades, women have overtaken men in college attendance and post-secondary degree attainme...

Animals often interact non-randomly with conspecifics, and association preferences can differ across life-history stages to maximize individuals' fitness. Mongolian gerbils (Meriones unguiculatus) are a social rodent that live in highly seasonal habitats and display seasonal fluctuations in population density, growth rate and the size of overlapped home ranges. Nevertheless, whether gerbils mod...

Skeletal characteristics vary among populations; therefore each population should have specific standards to optimize the accuracy of identification. Although many bones of skeleton present size related sexual differences, those of the hip bone usually displayed marked differences in morphology independent of size due to different reproductive functions mainly influenced by sex hormones. The di...

Sexual dimorphism is an important component of morphological variation and has been associated with a range of socioecological and cultural variables. Comparing patterns of dental sexual dimorphism in two Central European samples, Krapina and Pr fedmostí, may shed light on sexual differences in biocultural adaptation. However, studying sexual dimorphism in ancient populations needs to address m...

www.aafp.org/afp AMERICAN FAMILY PHYSICIAN 615 Epidemiology Based on the makeup of most studies published to date, oral burning appears to be most prevalent in postmenopausal women. It has been reported in 10 to 40 percent of women presenting for treatment of menopausal symptoms. These percentages are in contrast to the much lower prevalence rates for oral burning in epidemiologic studies (0.7 ...

1. The female-limited colour polymorphic damselfly Ischnura elegans has proven to be an interesting study organism both as an example of female sexual polymorphism, and in the context of the evolution of colour polymorphism. The study of colour polymorphism can also have broader applications as a model of speciation processes. 2. Previous research suggests that there exist correlations between ...

Can evolutionary and ecological dynamics operating at one level of the biological hierarchy affect the dynamics and structure at other levels? In social insects, strong hostility towards unrelated individuals can evolve as a kin-selected counter-adaptation to intraspecific social parasitism. This aggression in turn might cause intraspecific competition to predominate over interspecific competit...
