Sexual decision making, perceptions of responsibility for birth control and pregnancy, and knowledge of contraception and the consequences of teenage pregnancy were assessed among 251 high-risk seventh- and eighth-grade black, inner-city adolescents to determine these young peoples' need for information. Survey results indicated that these adolescents were aware of contraceptive methods, but lacked practical information about requirements for obtaining them or method effectiveness. Many students were uninformed about the circumstances under which pregnancy can occur. Males indicated a willingness to have intercourse, regardless of the contraceptives used, if any, and believed responsibility for use of a birth control method belonged to females. Females believed themselves to be responsible for contraceptive utilization and preferred intercourse with adequate protection. Both genders endorsed the notion of mutual responsibility for an unplanned pregnancy and related decisions. Implications for school-based family life education programs for young adolescents are discussed.This research was supported by grants from the Illinois Department of Children and Family Services and the Pittway Charitable Trust, to the Center for Health Services and Policy Research of Northwestern University; the project was administered by the Ounce of Prevention Fund. Portions of this paper were presented at the 112th annual meeting of the American Public Health Association at Anaheim, California, November 1984.

The report presents the case of a 33-year-old man under the primary assumption of homicide in which the court-ordered autopsy revealed death as a result of bleeding due to a spontaneous rupture of the urinary bladder. The article gives a short summary of the pathomorphological findings and their respective causes, for example the typical location of the rupture at the posterior wall and roof of the bladder and the common concomitant drunkenness. Furthermore, obligatory forensic investigations--beside the autopsy--are mentioned and discussed.  相似文献

This work presents a novel collection method for gunshot residues (GSR) using a sampling procedure based on ethylenediaminetetraacetic acid (EDTA) solution as a complexing agent on moistened swabs. Detection was via a sector-field inductively coupled plasma mass spectrometry (HRICP-MS). The proposed collection and analytical method allowed detection of antimony (Sb), barium (Ba) and lead (Pb) after .38 shot tests. at detection limits of less than 1 microg L(-1) in four different areas of the hands of volunteers. This paper includes a discussion concerning hand areas near the thumb and forefinger as being more suitable for GSR collection as well as a comparison between differences observed using 2% diluted EDTA. 2% nitric acid solution, and simple deionized water as collecting solutions, proving the superior efficiency of EDTA in GSR recoveries.  相似文献

Since 1960, it has been demonstrated by various analytical procedures that high concentrations of arsenic were present in Napoleon's hair. Various authors, indicating that the detected arsenic levels are a consequence of external contamination, have challenged the results of these examinations. We have tested two strands of hair, referenced as Noverraz and Grand Maréchal Bertrand. Samples were incubated 6 h in water at 90 °C, and arsenic speciation was carried out by HPLC–ICP/MS. The residue was injected on a cation-exchange PRP-X200 column that allows the detection of arsenobetaine and on an anion-exchange PRP-X100 column to test for the mineral forms. In these conditions, the inorganic species As(III), As(V) and their metabolites (DMA and MMA) were separated. Analysis of hair samples highlighted massive amounts of total arsenic (42.1 and 37.4 ng/mg). Arsenical species found in the two samples of analyzed hair are distributed in the following: As(III) 31.1 and 44.7%; As(V) 66.3 and 53.2%; DMA 0.42 and 0.15%. Traces of MMA were detected, and 2% of the species could not be identified. These results prove that more than 97% of the arsenic found in the hair of Napoleon is in inorganic form, which is consistent with a chronic intoxication to arsenic.  相似文献

In northern Uganda, children and youth once abducted by the notorious Lord's Resistance Army now live in internally displaced persons camps, facing challenging social, economic and security conditions. Within this context, former combatants state they would prefer to rearm than face a ‘painful’ and inevitable death. Drawing on qualitative interviews and focus group discussions with over 300 former combatants, we apply a socio-ecological lens to determine the push/pull factors that influence their decision to rearm or disarm. A lack of personal security, levels of stigmatisation and poor economic and educational opportunities are among the highest push factors toward rearmament. These findings point to a broad range of causes and actors responsible for child and youth militarisation and call for more holistic DDR approaches.  相似文献

ABSTRACT

Under what conditions are Disarmament, Demobilization and Reintegration (DDR) programs successfully implemented following intrastate conflict? Previous research is dominated by under-theorized case studies that lack the ability to detect the precise factors and mechanisms that lead to successful DDR. In this article, we draw on game theory and ask how the number of veto players, their policy distance, and their internal cohesion impact DDR implementation. Using empirical evidence from Nepal and the Democratic Republic of Congo, we show that the number of veto players, rather than their distance and cohesion, explains the (lack of) implementation of DDR.  相似文献

This series of studies extended procedural justice research to the informal domain of dispute resolution in intimate same-sex friendship. The first study identified the types of disputes that occur between friends and the concerns that friends have when choosing dispute resolution procedures. Seven dispute types and 11 procedural criteria were found relevant to dispute resolution in friendship. Study 2 assessed the importance of procedural criteria for resolving several dispute scenarios. As expected, ratings of criterion importance were affected by subject and disputant sex. Females rated four criteria as more important than did males, and one criterion was rated as more important in disputes involving a male and a female than in disputes involving two females. The importance of procedural criteria was also influenced by the type of dispute, but this effect was qualified by an interaction with the dispute version. It was suggested that the importance of procedural criteria is generally defined by the context of friendship and specifically defined by the dispute topic. In Study 3, the relations among subject sex, traditional fairness variables, and criterion-based measures of process control were examined. Consistent with studies in other domains, process control predicted procedural justice, and decision control predicted distributive justive. Moreover, the hypothesized fair process effect emerged as a function of speed, a criterion-based measure of process control.  相似文献

Nearly all relationships have power imbalances, none more so than age-dissimilar ones. Women writers of the early twentieth century addressed the issues of sexual innocence and ignorance in literary same-sex relationships with differing levels of perception and tangents of criticism. This article examines how innocence is portrayed, deployed and perceived in Clemence Dane’s Regiment of Women (1917), Rosamond Lehmann’s Dusty Answer (1927), Radclyffe Hall’s The Well of Loneliness (1928) and Mary Renault’s The Charioteer (1953) and how the idea of queerness complicates the issue of childhood innocence. It explores to what extent characters cast as innocent become vehicles for their female authors to express sexually and socially transgressive desires at a time when feminism was publicly and scientifically linked to lesbianism.  相似文献
