A large body of SES-Attainment studies has established the relationship between student’s socioeconomic background and academic achievement, making SES a single powerful predictor of student’s performance. Typically SES is measured as a composition of parental education, occupation and income. However, a variety of alternative measurement of SES has also been developed (White, 1982; Sirin, 2005...

background: disparities in health may relate to differences in nutrition. among dietary determinants, socioeconomic status (ses) plays an important role. therefore, this study was aimed to investigate the association between ses and cooking pattern and consumed food among rural and urban iranian households.     methods: overall, 14,136 households were selected through single-stage cluster sampl...

Emergence of green supply chain management could be attributed to the rising public awareness of environmental problems. Consumers say they increasingly prefer to purchase products that are produced with a minimum of pollution and with minimal environmental impact. Therefore, companies that successfully adopt a green policy can generate profits, reduce environmental impact, and provide positive...

The relationship between socioeconomic status (SES) and health changes as a society develops. In developed countries, high SES is associated with better health, but in developing countries, high SES is associated with poorer health. However, measuring SES is difficult in countries like India, where the traditional class and caste system are interwoven and complex. The current study explored the...

Low socioeconomic status (SES) during childhood confers risk for adverse health in adulthood. Accumulating evidence suggests that this may be due, in part, to the association between lower childhood SES and higher levels of pro-inflammatory cytokines. Drawing from literature showing that low childhood SES predicts exaggerated physiological reactivity to stressors and that lower SES is associate...

Research demonstrating that socioeconomic status (SES) differentials in health are smaller at older ages often considers only individual SES measures (e.g., income, education) but not community SES measures (e.g., community poverty rate), although the gerontological literature suggests that community context may be particularly salient in the lives of older adults. This study uses two national ...

Un anneau est un ensemble A muni de deux lois de composition internes + et × telles que (A,+) est un groupe commutatif d’élément neutre noté 0 et la loi × est associative et distributive à gauche et à droite par rapport à +. Si × admet un élément neutre 1 on dit que l’anneau est unitaire. Si × est commutative on dit que l’anneau est commutatif. L’anneau des matrices d× d pour d ≥ 2 est unitaire...

OBJECTIVES Few studies have explored the impact of neighbourhood socioeconomic status (SES) on health behaviours in youths in Germany. Our aim was to investigate the association of individual and neighbourhood SES with physical activity (PA) and screen time (ST) in students aged 12-13 years in Berlin. DESIGN Cross-sectional study. SETTING Secondary schools (high schools and integrated secon...

We demonstrate a negative relationship between pro-market reforms and the sustainability of superior profits in an emerging economy. The decline in sustainability of superior profits shows that pro-market reforms bring significant threats in addition to the various opportunities such as greater availability of production factors and greater freedom to enter and operate businesses highlighted in...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult to collude during periods of decreasing demand. We find that this prediction can be overturned if firm...
