Drought-induced inflation of cereal prices and the consequent turning of the terms of trade against livestock upset existing exchange entitlements and contributed to higher than normal mortality rates among the rural Beja populations in Red Sea Province in the early to mid-1980s. The Beja are agropastoralists who raise goats and sheep, and sow some sorghum. Their staples of consumption are goat milk and a prepared dish made with sorghum called asayda. They do not grow enough sorghum for household consumption, but they sell male goats in local markets in order to purchase sorghum. They also engage in a variety of minor activities to generate income for the purchase of sorghum.
In this article, data from two markets on cereal and livestock prices for the years 1980 to 1989 are examined. The objectives of the study were to examine market performance, especially that associated with the drought and famine in the mid-1980s in Red Sea Province, and to examine how the inflationary period from 1988 to 1990 differed from or resembled the early to mid-1980s. 相似文献

Since 1979, the potent narcotic analgesic fentanyl and its analogs have been synthesized in clandestine laboratories and sold as heroin substitutes. At least 112 overdose deaths have been associated with their use. In this study, toxicology data, autopsy findings, and coroners' investigative reports were reviewed in order to construct a profile of the typical fentanyl overdose victim and to identify any factors that might heighten the risk of death from fentanyl use. The "typical" fentanyl overdose victim was 32.5 +/- 6.7 years of age (range, 19 to 57 years), male (78%, compared with 22% female), and Caucasian (50%, compared with 29% Hispanic, 20% Black, and 0.9% Asian). With the exception of his or her age, the typical fentanyl overdose victim is quite similar to the typical heroin user. Nearly all the deaths (94%) occurred in California, yet within the state they were widely distributed throughout 17 counties and 44 cities. Pulmonary edema and congestion and needle puncture sites were consistent postmortem findings. No preexisting medical conditions were identified as possible risk factors. Although most of the fentanyl victims had a prior history of intravenous drug use, morphine or codeine were not commonly found, which suggests that the victims had little or no opiate tolerance. Ethanol was present in 38% of the cases and is thought to be a significant risk factor. Mean fentanyl concentrations in the body fluids were quite low: 3.0 +/- 3.1 ng/mL (0.3 +/- 0.31 micrograms/dL) in blood and 3.9 +/- 4.3 ng/mL (0.39 +/- 0.43 micrograms/dL) in urine, measured by radioimmunoassay. Although the potency of the analogs and the purity of street samples varies considerably, it is probably the general availability of the drug rather than the potency of a particular analog that determines the incidence of overdose deaths. 相似文献

This article identifies and describes the development of three parallel streams of literature about network theory and research: social network analysis, policy change and political science networks, and public management networks. Noting that these traditions have sometimes been inattentive to each other's work, the authors illustrate the similarities and differences in the underlying theoretical assumptions, types of research questions addressed, and research methods typically employed by the three traditions. The authors draw especially on the social network analysis (sociological) tradition to provide theoretical and research insights for those who focus primarily on public management networks. The article concludes with recommendations for advancing current scholarship on public management networks. 相似文献

Most past research on the effects of early pubertal timing on girls’ depressive symptoms and delinquent behavior has focused on either age of menarche or has combined multiple indicators of development into a single index of puberty. Past research has rarely examined both the onset of puberty such as age of menarche, as well more psychologically mediated impressions of puberty (i.e., perceived pubertal timing) within the same study. This study extends past research on racial differences and pubertal related effects on girls’ depressive symptoms and delinquent behavior by examining the independent influence of different indicators of puberty (age of menarche, development of breasts, and perceived pubertal timing). Two waves of data (100 % females) were used from African Americans (N = 481) and European Americans (N = 1259) who were enrolled in seventh- and eighth-grade during the first wave of data collection in the National Longitudinal Study of Adolescent Health. Early age of menarche was associated with high levels of depressive symptoms at Wave 1. Additionally, both early and late perceived pubertal timing were associated with high levels of depressive symptoms and high delinquent behaviors at Wave 1. The structural relationships among these variables were similar for African Americans and European Americans. Age of menarche and perceived pubertal timing influenced depressive symptoms and delinquent behavior at Wave 2 through depressive symptoms and delinquent behavior reported at Wave 1. The implications of these findings are discussed with an emphasis on how the specific indicator used to assess puberty is important in efforts to understand pubertal timing effects. 相似文献

Perceptions of racial discrimination constitute significant risks to the psychological adjustment of minority youth. The present study examined the relationship between perceived racial discrimination and peer nominations of victimization among 173 (55 % female) African American, European American and Latino youth. All respondents completed peer nominations of victimization status whereas the African American and Latino youth completed subjective measures of racial discrimination. The results indicated that African American and Latino’s subjective perceptions of racial discrimination were linked to nominations of overt and relational victimization when rated by their European American peers. The results suggest that there is consistency between African American and Latino youth’s perceptions of racial discrimination and nominations of peer victimization by their European American peers. 相似文献
