Too Many People and Too Few Livestock in West Africa? An Evaluation of Sandford's Thesis

We examine whether Stephen Sandford's (2006 Sandford, S. 2006b. “Too many people, too few livestock: the crisis affecting pastoralists in the Greater Horn of Africa”. Accessed at: http://www.future-agricultures.org/pdf%20files/Sandford_thesis.pdf [Google Scholar]b) ‘too many people, too few livestock’ thesis for the Greater Horn of Africa applies to West Africa. In a comparative study of seven pastoral systems across West Africa we found that pastoralists have generally successfully adapted to pressures on grazing resources. We describe three adaptive strategies: 1) integration and intensification in the Sudanian zone; 2) movement to the Sub-Humid zone; and 3) extensification in the Sahelian zone. We end by proposing four interrelated factors that account for the differences in pastoral systems between West Africa and the Greater Horn of Africa.     

The making of a public in a political campaign: A participant observation study

Abstract

The author served as a press assistant in the 1978 gubernatorial campaign of Ohio Lieutenant Governor Richard F. Celeste. This article examines the evolution of campaign strategy in the 1978 Democratic primary. Faced with token opposition, Celeste used the primary to introduce policies and establish themes for his general election campaign against incumbent James E. Rhodes. This study focuses on the Celeste campaign's efforts to identify and reach a particular constituency within the Ohio electorate. The “making of a public,” influenced by demographics and the results of opinion surveys, became a tentative, reactive process. The candidate's public identity and strategy were negotiated during the course of the primary campaign. Pressed by events and criticism from the press, the candidate eventually deemphasized the specifics of issues as he sought to redefine himself for a public of voters.     

Error Rates in Forensic Child Sexual Abuse Evaluations

When mental health, medical, and social work professionals and paraprofessionals make false positive or false negative errors in their judgments about the validity of allegations of child sexual abuse, the consequences can be catastrophic for the affected children and adults. Because of the high stakes, practitioners, legal decision makers, and policy makers should have some idea of the magnitude and variability of error rates in this domain. A novel approach was used to estimate individual error rates for 110 professionals (psychologists, physicians, social workers, and others) who conduct or participate in forensic child sexual abuse evaluations. The median estimated false positive and false negative error rates were 0.18 and 0.36, respectively. Estimated error rates varied markedly from one participant to the next. For example, the false positive error rate estimates ranged from 0.00 to 0.83. These estimates are based on participants’ self-reported substantiation rates and on their subjective frequency distributions for the probability of truth for the abuse allegations they evaluate.
