Observers argue that the business of news is responsible for worsening the coverage of terrorism, but exactly how economic considerations influence coverage is controversial. Based on an analysis of over 1600 articles from The Washington Post and USA Today, we find that concerns about the effects of economic pressures on terrorism reporting are exaggerated. The business climate affects coverage, but the long-term impact of market pressures on coverage is modest. Articles about terrorist violence are increasingly prominent, but coverage of counterterrorism remains robust. Efforts to inoculate the press against the worst excesses of the market are unnecessary. 相似文献

Abstract Three hypotheses seek to explain the persistence of residential segregation between blacks and whites in the United States: economic differentials, discrimination in housing and lending markets, and neighborhood preferences. The preferences hypothesis posits that both races wish to live in racially homogeneous neighborhoods. This article examines the preferences hypothesis by using recent interview data from metropolitan Atlanta, Boston, Detroit, and Los Angeles. Race continues to be significant in the residential decision‐making process. Whites’ willingness to move into a neighborhood is inversely related to the density of blacks living there. Blacks prefer integrated neighborhoods, but ones with a substantial representation of blacks. Preferences differ significantly from one metropolis to another, with Detroit representing the extreme. In the other three metropolises, the preferences of blacks and whites do overlap sufficiently to offer hope for a decline in segregation, provided that the influence of other forces, particularly discrimination, also declines. 相似文献

Infant death scene investigation and the assessment of potential risk factors for asphyxia: a review of 209 sudden unexpected infant deaths 总被引:1,自引:0,他引:1
At the Wayne County Medical Examiner Office (WCMEO) in Detroit, Michigan, from 2001 to 2004, thorough scene investigations were performed on 209 sudden and unexpected infant deaths, ages 3 days to 12 months. The 209 cases were reviewed to assess the position of the infant at the time of discovery and identify potential risk factors for asphyxia including bed sharing, witnessed overlay, wedging, strangulation, prone position, obstruction of the nose and mouth, coverage of the head by bedding and sleeping on a couch. Overall, one or more potential risk factors were identified in 178 of 209 cases (85.2%). The increasing awareness of infant positions at death has led to a dramatic reduction in the diagnosis of sudden infant death syndrome at the WCMEO. This study suggests that asphyxia plays a greater role in many sudden infant deaths than has been historically attributed to it. 相似文献

There is a world of difference between teaching negotiation theory, which pertains to conceptual understanding, and teaching negotiation skills, which pertain to actual behavior in real‐world situations. The principle of reflective practice is widely used for theoretical instruction. Deliberate practice, however, is a more powerful model for skills training. Cognitive scientists have discovered that subjects will learn skills best when they perform well‐defined tasks at appropriate levels of difficulty, and when they are given immediate feedback, an opportunity to correct their errors, and an opportunity to practice until the tasks become routine. To satisfy the deliberate practice conditions for large graduate‐level negotiation courses (some as large as seventy students), students were assigned to use webcams with their laptop computers to video record their negotiation exercises. Before each exercise, students were assigned to prepare for and to concentrate on performing two or three well‐defined tasks. Students reviewed these recordings and commented on their performances in a journal before uploading the videos and journals to an assigned network folder. The instructor and teaching assistants then reviewed the journals and specified portions of the videos and provided individual written feedback to the students. The instructors found that student negotiating skills have improved significantly using this new system. In comparison with earlier semesters, students also felt they were involved in a more intense and personal learning experience. A majority of students reported they intend to apply the principles of deliberate practice in their professional lives after graduation. The authors have found this method continues to challenge their ability to identify and describe the skills used by expert negotiators. As an addition to this new methodology, two of the authors have spearheaded the development of video annotation software, known as “MediaNotes,” to help students and instructors review, comment upon, and learn from video recordings of negotiations. Based on their experiences using the software to support deliberate practice, the authors expect this tool to initiate a significant advance in our ability to recognize and describe expert negotiation behavior and in students’ ability to improve their negotiating skills. 相似文献
