Food insecurity in the urban poor is a major public health challenge. The Health, Environment and Development study assessed trends in food insecurity and food consumption over a period of 7 years in an informal settlement in Johannesburg, South Africa (SA). Annual cross-sectional surveys were conducted in the informal settlement (Hospital Hill). The degree of household food insecurity decrease...

This research evaluates the connection between corruption, economic development, and insecurity in several Colombian departments. This chapter explores the dynamics of these variables using two empirical techniques: the Data Envelopment Analysis (DEA) and the Dynamic Panel Data Model (DPDM). DEA is performed to evaluate social performance in terms of corruption, economic development, and insecu...

This paper analyzes the impact of job insecurity perceptions on individual well-being. While previous studies on the subject have used the concept of perceived job insecurity rather arbitrarily, the present analysis explicitly takes into account individual perceptions about both the likelihood and the potential costs of job loss.

Work conditions characterized by uncertainty and ambiguity are potential stressors for employees. One such stressor is job insecurity. This longitudinal study of 207 automobile manufacturing workers indicates that chronic job insecurity is predictive of changes over time in both job satisfaction and physical symptoms. Extended periods of job insecurity decrease job satisfaction and increase phy...

Subjective insecurity is a key determinant of different forms of prosocial behavior. In Study 1, we used field experiments with farmers in Colombian villages exposed to different levels of violence to investigate how individual perceptions of insecurity affect cooperation, trust, reciprocity and altruism. To do so, we developed a cognitive-affective measure of subjective insecurity. We found th...

METHODS Data from a study of adults randomly selected from the membership list of the Mood Disorder Association of British Columbia (n = 97), Canada, were analyzed. ...

Food insecurity is a pressing public health concern in many developing countries. Despite widespread interest in the sociocultural determinants of food insecurity, little is known about whether youths living in food insecure households experience food insecurity. The buffering hypothesis reviewed here assumes that, to the extent possible, adult members of households will buffer younger househol...

BACKGROUND While statistics is increasingly taught as part of the medical curriculum, it can be an unpopular subject and feedback from students indicates that some find it more difficult than other subjects. Understanding attitudes towards statistics on entry to graduate entry medical programmes is particularly important, given that many students may have been exposed to quantitative courses in...
