Three experiments investigated the effects of positive mood on perceptions of variability within and between groups. Participants formed impressions of two different and highly variable groups under a neutral or positive mood. When participants expected to learn about both groups, positive mood increased perceived intergroup similarity but did not affect perceived intragroup variability. In contrast, when participants expected to learn about only one group, judgments of intergroup and intragroup similarity were both affected by mood. Mood and the intergroup context influenced the nature and degree of information processing and resultant judgments of variability in social groups.

The current study compared the factor structures of the construct of organizational commitment between two samples of financial employees, one from the U.S. ( n = 103) and one from South Korea ( n = 109). Participants completed a 26-item questionnaire. Two factors (an affective component and a normative component) emerged for the U.S. sample; only one factor for the Koreans. Results suggest that culture should be considered when trying to assess organizational commitment.

This article examines the clash between stakeholder- and shareholder-based business systems resulting from an increase in foreign portfolio investment in the Japanese economy during the 1990s. An analysis of 1,108 firms between 1991 and 2000 shows that as foreign institutional investors, who were more interested in investment returns than in long-term relationships, replaced domestic shareholders, one fundamental pillar of Japan's stakeholder capitalism began to crack. Japanese firms began to adopt downsizing and asset divestiture, practices more characteristic of Anglo-American shareholder economies. The influence of foreigners, however, was weaker in firms more deeply embedded in the local system through close ties to domestic financial institutions and corporate groups. Thus, foreign investors were influential primarily in firms less embedded in the existing stakeholder system. This research contributes to debates on globalization and convergence of business systems, institutional change, and corporate governance systems.

The purpose of this prospective study was to determine if fiberoptic endoscopic evaluation of swallowing (FEES) maintains high intra- and interrater reliability in detecting pharyngeal dysphagia and aspiration without the addition of FD&C Blue No. 1 to food. Twenty consecutive adults referred for a swallow evaluation participated. Nine subjects received blue-dyed food and 11 subjects received regular nondyed food, i.e., yellow pudding and white skim milk. Four variables were rated: (1) the stage transition characterized by depth of bolus flow to at least the vallecula prior to the pharyngeal swallow; (2) evidence of bolus retention in the vallecula or pyriform sinuses after the pharyngeal swallow; (3) laryngeal penetration defined as material in the laryngeal vestibule but not passing below the level of the true vocal folds either before or after the pharyngeal swallow; and (4) tracheal aspiration defined as material below the level of the true vocal folds either before or after the pharyngeal swallow. Three speech–language pathologists experienced in interpreting FEES results independently and blindly reviewed the digitized videotape three times. Intrarater agreements for the four variables with blue-dyed and non-blue-dyed food trials were 100% and monochrome trials ranged from 95% to 100%. Average kappa values for interrater reliability ranged from moderate to excellent agreement (0.61–1.00) for all viewing conditions. Kappa values for blue-dyed trials versus monochrome trials were 0.83 and for non-blue-dyed trials versus monochrome trials were 0.88, indicative of excellent reliability under both viewing conditions. FEES maintains both high intra- and interrater reliability in detecting the critical features of pharyngeal dysphagia and aspiration using either blue-dyed or non-blue-dyed foods. The endoscopist, therefore, can be assured of reliable FEES results using regular, non-dyed food trials.

Results from sabbatical resulted in grants, peer review and extensive exhibitions. Several paintings were done examining the traditions of food as a subject in still life using genetically modified food.

"Race, Ethnicity, and the American Urban Mainstream uses history, biography, and sociological analysis to examine the achievements and struggles of racial and ethnic groups in American cities. This text is organized around social systems (politics, housing, education, economics, and work) rather than groups or concepts such as prejudice and discrimination. A group of in-depth profiles of minority communities, in cities such as Oakland, Detroit, Los Angeles, and Chicago, help to illustrate major concepts."--BOOK JACKET.

"In a series of influential essays that appeared in Harper's, W.D. Howells argued for literature as a vehicle for social change. Literature could and should, Howells suggested, mediate across divisions of class and region, fostering cross-cultural sympathies that would lead to comprehensive social and ethical reform." "Paul R. Petrie explores the legacy of Howells's beliefs as they manifest themselves in his fiction and in the works of three major American writers - Charles W. Chesnutt, Sarah Orne Jewett, and Willa Cather. Each author struggled to adapt Howells's social-ethical agenda for literature to his or her own aesthetic goals and to alternative conceptions of literary purpose. Jewett not only embraced Howell's sense of social mission but also extended it by documenting commonplace cultural realities in a language and vision that was spiritual and transcendent. Chesnutt sought to improve relations between Anglo readers and African Americans, but his work, such as The Conjure Woman, also questions literature's ability to repair those divides." "Finally, Petrie shows how Cather, as she shifted from journalism to fiction writing, freed herself from Howells's influence. Alexander's Bridge (1912) and O Pioneers! (1913) both make reference to social and material realities but only as groundwork for character portrayals that are mythic and heroic. The result of Petrie's exploration is a refreshing reassessment of Howell's legacy and its impact on American literature and social history at the turn of the century."--Jacket.
