Although much has been learned about the role firms play in the labor market, whether establishments within the same firm adopt similar labor-market practices is an open question. This question is particularly relevant for firms with establishments in different locales and industries. For example, a finding that wages within a firm have a common component across unrelated workers and industries...

background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...

Background: Based on the studies which have investigated conscious and unconscious processes, simple arithmetic operations such as addition and multiplication can be automatically processed in the brain and affect subsequent responses. However, most studies have focused on addition and multiplication of one-digit numbers. In this research we used subliminal priming paradigm to assess automatic ...

Abstract This study aims to identify critical consumer-demographic characteristics associated with the consumption of products containing hemp and investigate their effect on total expenditure in USA. To estimate likelihood market participation level, Heckman selection model is employed utilizing Nielsen consumer panel data from 2008 2015. Using a model, this finds that socio-demographic charac...

Prenatal sex steroids play a vital role in the development of the whole organism, and therefore also the brain. Exposure of the fetus to testosterone seems to be of special importance both for typical development and pathology. The key factor impacting offspring development (including prenatal androgen levels) appears to be diet, both in terms of shortage and excessive intake of certain food pr...

Sexual dimorphism in ventrally measured digit ratios (2D:4D and other) has been related to prenatal sex-hormone levels. In the present series of three studies, we measured all digit lengths (excluding the thumb) on the dorsal, rather than the ventral, side of left and right hands and investigated the sexual dimorphism in digit ratios in three independent samples, two of them comprising adults (...

Little is known about the effect of normal-range blood pressure (BP) on cognitive function. In previous studies investigating the relationship between BP and cognitive function in elderly subjects, underlying cerebrovascular damage has complicated the interpretation of results. To reveal the relationship between BP levels that were within an absolutely normal range and cognitive function, we ex...

A growing body of literature suggests that the ratio of the lengths of the second to fourth digits (2D:4D) on human hands is sexually dimorphic and associated with prenatal exposure to gonadal hormones, circulating serum testosterone, and a number of psychological and behavioral measures. Little research has investigated digit ratios in nonhuman species. In the present study, we investigated se...
