BACKGROUND This study is the first to examine the relationship between gender and self-assessed health (SAH), and the extent to which this varies by socioeconomic position in different European welfare state regimes (Liberal, Corporatist, Social Democratic, Southern). METHODS The EUROTHINE harmonised data set (based on representative cross-sectional national health surveys conducted between 1...

Facial cues contribute to attractiveness, including shape cues such as symmetry, averageness, and sexual dimorphism. These cues may represent cues to objective aspects of physiological health, thereby conferring an evolutionary advantage to individuals who find them attractive. The link between facial cues and aspects of physiological health is therefore central to evolutionary explanations of ...

In a recent study, Amsalem, Orlova & Grozinger (2015) performed experiments with Bombus impatiens bumblebees to test the hypothesis that saturated cuticular hydrocarbons are evolutionarily conserved signals used to regulate reproductive division of labor in many Hymenopteran social insects. They concluded that the cuticular hydrocarbon pentacosane (C25), previously identified as a queen pheromo...

Depression debilitates the lives of millions and is projected to be the second leading disease burden worldwide by 2020. At the population level, the causes of depression are found in the everyday social and physical environments in which people live. Research has shown that men and women often experience neighbourhood environments differently and that these variations are often reflected in he...

Research into the detrimental effects of excessive exercise has been conceptualized in a number of similar ways, including 'exercise addiction', 'exercise dependence', 'obligatory exercising', 'exercise abuse', and 'compulsive exercise'. Among the most currently used (and psychometrically valid and reliable) instruments is the Exercise Addiction Inventory (EAI). The present study aimed to furth...

Theory suggests that frequency-dependent resource competition will disproportionately impact the most common phenotypes in a population. The resulting disruptive selection forms the driving force behind evolutionary models of niche diversification, character release, ecological sexual dimorphism, resource polymorphism, and sympatric speciation. However, there is little empirical support for the...

Nowadays, “Smart City” is a very growing and promoting concept. Unlike other concepts related to cities, like digital or green city, it encompasses all technological, human and institutional factors. However, there are too many different viewpoints and definitions of this concept in the literature. The problem statement of this research is that despite the existence of many points of view and d...

Three novel families of transposable elements, Wukong, Wujin, and Wuneng, are described in the yellow fever mosquito, Aedes aegypti. Their copy numbers range from 2,100 to 3,000 per haploid genome. There are high degrees of sequence similarity within each family, and many structural but not sequence similarities between families. The common structural characteristics include small size, no codi...
