This study examined the criteria news media use to evaluate the newsworthiness of homicide incidents occurring between the years of 1997 to 2005. By examining how particular race, gender, and race/gender intersections of offender-victim combinations affect news coverage decision-making, this study attempted to identify the most important criteria of newsworthiness. This article contributes to the growing body of newsworthiness of crime research by examining how cultural typification of victims and offenders affects news media coverage of homicides in Newark, New Jersey, a unique research location in which Blacks make up the majority of the population and Hispanics are the dominant population minority. The results provide partial support for Lundman's (2003) conclusion that cultural typification based on race and gender is an important criterion of newsworthiness. 相似文献

Understanding human aggression: New insights from neuroscience 总被引:1,自引:0,他引:1
The present paper reviews and summarizes the basic findings concerning the nature of the neurobiological and behavioral characteristics of aggression and rage. For heuristic purposes, the types of aggression will be reduced to two categories — defensive rage (affective defense) and predatory attack. This approach helps explain both the behavioral properties of aggression as well as the underlying neural substrates and mechanisms of aggression both in animals and humans. Defensive rage behavior is activated by a threatening stimulus that is real or perceived and is associated with marked sympathetic output. This yields impulsivity with minimal cortical involvement. Predatory attack behavior in both animals and humans is generally planned, taking minutes, hours, days, weeks, months, or even years (with respect to humans) for it to occur and is directed upon a specific individual target; it reflects few outward sympathetic signs and is believed to require cortical involvement for its expression. Predatory attack requires activation of the lateral hypothalamus, while defensive rage requires activation of the medial hypothalamus and midbrain periaqueductal gray (PAG). Both forms of aggressive behavior are controlled by components of the limbic system, a region of the forebrain that is influenced by sensory inputs from the cerebral cortex and monoaminergic inputs from the brainstem reticular formation. Control of aggressive tendencies is partly modifiable through conditioning and related learning principles generated through the cerebral cortex. 相似文献

The location, type, and local mechanism of tibial shaft fracture were determined for 66 drivers injured in frontal automobile crashes. The results from the analyses showed that the distal third is the most common fracture location (p<0.05) and that bending is responsible for the majority of these fractures regardless of the fracture site. These findings indicate that the current injury criterion for predicting the occurrence of tibial shaft fracture in crash tests with anthropometric test devices is appropriate in terms of accounting for the primary mechanism of fracture but that increased protective effectiveness could be achieved by redefining the criterion for the distal third shaft section instead of the currently specified mid-shaft section of the tibia. 相似文献
