Over the course of 30 years of academic work, the late educational anthropologist John Ogbu had an enormous influence on educational research, and on educational anthropology in particular. In this paper, I lay out the tenets of his cultural-ecological (CE) theory of minority student responses to schooling. I also offer critical commentary and point out ways in which CE theory can be sharpened ...

OBJECTIVE Although the sociodemographic characteristics of food-insecure households have been well documented, there has been little examination of neighbourhood characteristics in relation to this problem. In the present study we examined the association between household food security and neighbourhood features including geographic food access and perceived neighbourhood social capital. DES...

The Nannochloropsis genus contains oleaginous microalgae that have served as model systems for developing renewable biodiesel. Recent genomic and transcriptomic studies on Nannochloropsis species have provided insights into the regulation of lipid production in response to nitrogen stress. Previous studies have focused on the responses of Nannochloropsis species to short-term nitrogen stress, b...

BACKGROUND Glasgow's low life expectancy and high levels of deprivation are well documented. Studies comparing Glasgow to similarly deprived cities in England suggest an excess of deaths in Glasgow that cannot be accounted for by deprivation. Within Scotland comparisons are more equivocal suggesting deprivation could explain Glasgow's excess mortality. Few studies have used life expectancy, an ...

BACKGROUND There is scant research that simultaneously analyzes the joint effects of long-term unemployment, poverty and public expenditure policies on poorer self-perceived health during the financial crisis. The aim of the study is to analyze the joint relationship between long-term unemployment, social deprivation, and regional social public expenditure on one side, and self-perceived health...

BACKGROUND Association between deprivation and health is well established, particularly among unemployed or fixed-term contract or temporary contract subjects. This study aimed to assess if this relationship existed as well in full-time permanent workers. METHODS Biometrical, biological, behavioural and psychosocial health risk indicators and an individual deprivation score, the Evaluation of...

Each sleep phase is characterized by specific chemical, cellular and anatomic events of vital importance for normal neural functioning. Different forms of sleep deprivation may lead to a decline of cognitive functions in individuals. Studies in this field make a distinction between total sleep deprivation, chronic sleep restriction, and the situation of sleep disruption. Investigations covering...

Even short periods of early monocular deprivation result in reduced cortical representation and visual acuity of the deprived eye. However, we have shown recently that the dramatic deprivation effects on vision can be prevented entirely if the animal receives a brief period of concordant binocular vision each day. We examine here the extent to which the cortical deprivation effects can be count...

Two recent studies have independently demonstrated that short periods of visual deprivation early in human development can have long-term functional consequences on sensory perception and on the balance between auditory and visual attention.
