The reliability of eyewitness identification

This study examines the effects of 14 estimator variables (e.g., disguise of robber, exposure time, weapon visibility) and system variables (e.g., lineup instructions, exposure to mugshots) on a number of measures of eyewitness performance: identification accuracy, choosing rates, confidence in lineup choice, relation between confidence and identification accuracy, memory for peripheral details, memory for physical characteristics of target, and time estimates. Subjects viewed a videotaped reenactment of an armed robbery and later attempted an identification. Characteristics of the videotape and lineup task were manipulated. Prominent findings were as follows: identification accuracy was affected by both estimator and system variables including disguise of robber, weapon visibility, elaboration instructions, and lineup instructions. Memory for peripheral details was positively correlated with choosing on the identification task but negatively correlated with identification accuracy.     

STATE LEGISLATORS AND ECONOMIC DEVELOPMENT: UNIVERSITY-INDUSTRY RELATIONSHIPS AND THE ROLE OF GOVERNMENT IN BIOTECHNOLOGY

This article presents a detailed examination of some key political dimen- sions underlying cooperative research in agricultural biotechnology among state land-grant universities, state legislatures, and biotechnology corpora- tions. Factor analysis and path analysis methods are employed to assess differences in the perceptions of university administrators, biotechnology corporation researchers, and state legislators, using national and state survey data. Two attitudinal dimensions, one regarding cooperation among university and corporate researchers, and the other regarding barriers to joint research, are extracted. Generally similar attitudes are shared by university and legislative respondents, who are concerned over the prospects of market-oriented university research. In contrast, corporate respondents are more concerned with reducing barriers to cooperative research and the need for more open communication between academia and industry, and with issues of patent rights. Extensions of this work to other states and to other high-technology industries are considered.     

Oxaliplatin: a 'basic' patent problem

In an application for a declaration of non-infringement withrespect to a patent claiming a method of preparation for a drug,a claim specifying that the pH is adjusted to be between 3.0and 6.0 by adding an alkali solution required a distinct additionof alkali and was not infringed by use of a reagent that yieldeda pH within the specified range without the need for separateaddition of alkali.     

Perceived Support and Internalizing Symptoms in African American Adolescents: Self-Esteem and Ethnic Identity as Mediators

Existing research leaves a gap in explaining why African American adolescents do not exhibit more anxiety and depression than other youth, at the same time that they experience more contextual risk factors. The current study examined the roles of social support as well as possible mediators self-esteem and ethnic identity (sense of belonging to one’s ethnic group) in reducing internalizing symptoms in 227 African American adolescents (mean age = 12.55). Structural equation models indicated that self-esteem and ethnic identity partially mediated the relation between social support and depression. For depression, ethnic identity accounted for more of the social support effect for males, whereas self-esteem had more impact for females. The mediation model for anxiety was supported in females, with self-esteem more important than ethnic identity. The results suggest that ethnic identity and self-esteem function as important links in how social support reduces internalizing symptoms in African American youth.
