To analyse corporate social responsibility (CSR) as a business tool and as a way to promote food security in the global South, this article draws on 65 interviews with supply chain personnel and a 2013 survey of 250 smallholder farmers in Nicaragua. Contrary to private governance literature, Walmart's efforts to control supply chains in Nicaragua are not advancing rural sustainability; feelings of mistrust and unfairness persist among farmers, and many are returning to local markets to regain independence. This analysis extends our understanding of why CSR is failing to help agrarian societies and confirms CSR as principally a business strategy.  相似文献

Current challenges in medical practice, research, and administration demand physicians who are familiar with bioethics, health law, and health economics. Curriculum directors at American Association of Medical Colleges-affiliated medical schools were sent confidential surveys requesting the number of required hours of the above subjects and the years in which they were taught, as well as instructor names. The number of relevant publications since 1990 for each named instructor was assessed by a PubMed search. In sum, teaching in all three subjects combined comprises less than two percent of the total hours in the American medical curriculum, and most instructors have not recently published articles in the fields they teach. This suggests that medical schools should reevaluate their curricula and instructors in bioethics, health law, and health economics.  相似文献

By looking at the autoplay videos posted and shared on Hillary Clinton’s Facebook account during the 2015 Facebook. 2015. “The Value of Video for Brands.” Webpage Accessed 28 April 2017. https://www.facebook.com/business/news/value-of-video [Google Scholar]/2016 Clinton, H. 2016. “A Special Moment during a Meeting with the Union of Peasants. Yes You Can! Watch the Video. Facebook Status Update.” Retrieved 20 November 2016. https://www.facebook.com/hillaryclinton/posts/1090969694292892 [Google Scholar] primary election season, this article offers much needed insight into the communication aspect of campaign targeting. Using data analysis extracted from the leading social media platform, the article examines what groups of Hispanic Facebook users were attracted to Clinton’s targeted autoplay videos, what elements within these videos best enticed these people into liking the videos, and if the Clinton campaign appeared to learn what types of autoplay videos were most effective over the course of the primary season.  相似文献

This article seeks to examine the area characteristics that act as determinants of area property crime levels, namely, incidence and prevalence. The crime figures are extracted from the 1984 British Crime Survey. Area characteristics are taken from the 1981 UK census. Initial exploratory analysis considers the non-Gaussian nature of the crime data, the statistical implications of this, and the transformations used to overcome these problems. In addition, possible regional and inner-city/non-inner-city variations are considered. The later stages move from simple individual correlations to multiple regression models. Three regression models are considered and the reasons for refining these are explored, with the results indicating that both area characteristics and regional influences play a role as determinants of the area crime level. In particular, population density and the area population age profile have significant roles to play. The conclusions support the recent revival of the application of ecological concepts in the analysis of crime levels.  相似文献

Stressful transitions in adolescence increase depressive symptoms, especially among girls. However, little is known about this risk as adolescents mature into young adulthood, especially about how parental support affects depression trajectories during this period. Using the National Longitudinal Study of Adolescent Health, this analysis investigates the role of gender in structuring the associations among stressful life events, parental support, and depression. Females reported more depressive symptoms at the outset of the study, a rank order that persisted along declining depression trajectories into young adulthood. In addition, stress accounts for the decline in trajectories for females but not males. Support from both parents has a salubrious effect on mental health, regardless of gender, but this effect dissipates as adolescents age into adulthood.  相似文献

The relationship between economic hardship and adolescent aggression has been explored from various perspectives. Using survey and observational data on two-parent families in a midwestern rural county, the study identifies four important mechanisms that link economic hardship to the aggressive behavior of adolescents. Economic pressure stemming from low income, financial loss, and unstable work, adversely affects the marital relationship through the negativity of fathers. Negative marital interactions increase irritable parenting, making adolescent aggression more likely.This paper is based on collaborative research involving the Iowa Youth and Families Project at Iowa State University, Ames, and the Social Change Project at University of North Carolina — Chapel Hill. The combined research effort is currently supported by the National Institute of Mental Health (MH43270), the National Institute on Drug Abuse (DA05347), the John D. and Catherine T. MacArthur Foundation Program for Successful Adolescence, the Bureau of Maternal and Child Health (MCJ-109572), and a Research Scientist Award (MH00567).Ph.D. in sociology from University of North Carolina at Chapel Hill.

Sexual harassment has been investigated mostly in developed countries. The authors examined frequency rates and consequences of sexual harassment among female domestic workers in Brazil. Twenty-six percent had been sexually harassed at work during the past year. Live-in workers were at significantly greater risk for experiencing sexual harassment than those residing in their own homes, when controlling for participants' age, race, and social class. Women residing in their employers' residences used more alcohol and drugs than their counterparts. Harassed women had significantly higher self-esteem impairment and anxiety and depression than nonharassed women. Nonharassed women residing in their own homes had the best physical well-being. Concerning participants' worst sexually harassing experiences, the perpetrators were likely to be men (75%), who also engaged in more severe types of sexual harassment than female perpetrators. The emotional reactions to such incidents were significantly more negative when perpetrated by men than by women. Implications for foreign in-home workers employed by Europeans and North Americans are discussed.  相似文献
