Although flag burnings today rarely draw the amount of attention they received in the late 1980s, efforts to protect the flag have persisted for nearly a decade. Accordingly, the flag protection campaign has captured the interest of intellectuals from various academic backgrounds, including political scientists, egal scholars, and journalists. Conspicuously absent from the literature on flag desecration, however, are sociologists and criminologists. Combining historical evidence with recent cases, this article unveils key sociological aspects of social control, including formal and informal responses to flag desecration.  相似文献

This study examined the pharmacological and psychological effects of alcohol on women’s recognition of and response to dating sexual aggression. Female participants completed measures of prior sexual victimization experiences, sex related alcohol expectancies, general alcohol expectancies, and drinking habits. Using a 2 (alcohol) × 2 (expectancy) balanced placebo research design, women were exposed to an audiotape date rape vignette and asked to press a button when the man’s sexual advances had gone to far. Upon pressing the button, the tape was stopped and participants were instructed to imagine themselves in the same situation and generate a response describing what they would say and/or do at that point. Results indicated that although alcohol and expectancy were not related to risk perception, individuals who consumed alcohol displayed significantly less resistant role play refusals. A significant interaction between expectancy set and pre-existing sex-related alcohol expectancies was observed indicating participants believing alcohol affects sexual behavior generated less resistant refusal responses when they expected to receive alcohol. Moreover, for those who expected to receive alcohol, stronger pre-existing sex-related alcohol expectancies predicted less resistant refusal responses over above the effects of blood alcohol level and general alcohol expectancies. The implications of these findings are discussed.  相似文献

This article presents an overview of the Ojibwa family over the past three centuries, from early European contacts to the present. It emphasizes the extent to which Ojibwa familial relations have long been embedded in extensive networks of kin that played major roles in the family lives of individuals of all ages. The article traces the effects of historical change on the Ojibwa family and examines continuity within Ojibwa kinship relations. The changes of the last century have taken a heavy toll on these relationships, yet, where they persist or are being revived, they are sources of strength and renewal.  相似文献

Human blood is the body fluid most commonly encountered at crime scenes, and blood detection may aid investigators in reconstructing what occurred during a crime. In addition, blood detection can help determine which items of evidence should be processed for DNA-STR testing. Unfortunately, many common substances can cause red-brown stains that resemble blood. Furthermore, many current human blood detection methods are presumptive and prone to false positive results. Here, the developmental validation of a new blood identification test, Rapid Stain Identification™-Blood (RSID™-Blood), is described. RSID™-Blood utilizes two anti-glycophorin A (red blood cell membrane specific protein) monoclonal antibodies in a lateral flow strip test format to detect human blood. We present evidence demonstrating that this test is accurate, reproducible, easy to use, and highly specific for human blood. Importantly, RSID™-Blood does not cross-react with ferret, skunk, or primate blood and exhibits no high-dose hook effect. Also, we describe studies on the sensitivity, body fluid specificity, and species specificity of RSID™-Blood. In addition, we show that the test can detect blood from a variety of forensic exhibits prior to processing for DNA-STR analysis. In conclusion, we suggest that RSID™-Blood is effective and useful for the detection of human blood on forensic exhibits, and offers improved blood detection when compared to other currently used methods.  相似文献
