This introductory article argues that the current state of debate on television within cultural studies is marked by considerable areas of theoretical and political uncertainty. The spread of deregulatory and privatizing public policies in relation to television, and the disarticulation of television from the idea of the national community and from the role of the citizen, have posed new problems for theorizing the relation between television and its audiences. In this article I survey a number of key areas of debate: the relation between television, the nation and the state; television and the citizen/consumer, television content and performance, and the likely future(s) of television.

Cytokines produced by T-cells in periodontal lesions may determine the nature of the adaptive immune response. Since different antigen-7 presenting cells (APC) may direct the Th1/Th2 response, P. gingivalis-specific T-cell lines were established by different APC subpopulations, and their cytokine profiles were determined. Peripheral blood mononuclear cells induced similar percentages of IL-4+ and IFN-gamma+ T-cells and lower percentages of IL-10+ T-cells, Epstein-Barr virus-trans formed B-cells (LCL) induced higher percentages of IL-4+ cells than IFN-gamma+ cells, with lower percentages of IL-10+ cells. Peripheral blood mononuclear cells induced a higher percent of IFN-gamma+ CD8 cells than LCL (p = 0.004). Purified B-cells, monocytes, and dendritic cells induced similar percentages of IL-4+ and IFN-gamma+ cells, although again, the percentage of IL-10+ cells was lower. The results of the present study have demonstrated that, as measured by FACS analysis of intracytoplasmic cytokines, P. gingivalis-specific T-cells produce both Th1 and Th2 cytokines, regardless of the APC population.

The adoption of the incorporated form of ownership in preference to partnership is linked to the shift to a more modem organizational archetype in professional firms. Yet existing empirical research offers insufficient insight into the organizational processes of this transformation in different professional arenas. Where ownership and control become separated, there is a clearer theoretical explanation of the implications for the way the firm is run. Where ownership and control remain inside, the firm, however, the consequences are not so clear and have not been well explored. Using survey and interview materials derived from a study of architecture practices, we examine the processes by which differences based on ownership emerge. Then, by drawing on Weberian theories, where they are concerned with professionalization as a project with material and social rewards, we specify more clearly the context for change in professional firms' archetypes. This, we conclude, provides a stronger basis for understanding the change trajectories of firms within professions and comparative organizational analysis between professions.

Leadership is a perennially popular topic in the academic and practitioner literature on management. In particular, the past twenty years have witnessed an explosive growth of interest in what has been termed 'transformational leadership' (henceforth, TL). The theory is closely linked to the growth in what has been defined as corporate culturism - an emphasis on the importance of cohereat cultures, as a means of securing competitive advantage. This article outlines the central components of TL theory, and subjects the concept to a critical analysis. In particular, similarities are identified between the components concerned and the characteristics of leadership practice in organizations generally defined as cults. This connection has been previously unremarked in the literature. These similarities are comprehensively reviewed. Trends towards what can be defined as corporate cultism in modem management practice are also discussed. We conclude that TL models are overly concerned with the achievement of corporate cohesion to the detriment of internal dissent Such dissent is a vital ingredient of effective decision-making. It is suggested that more inclusive and participatory models of the leadership process are required.

The motivation for concern about the environment beyond one's neighborhood is still relatively poorly understood. This article examines the determinants of feelings of responsibility at a regional watershed level. Using demographic, attitudinal, self-reported behavior and neighborhood mapping measures from four cities in Australia, five hypotheses were derived. These were that wider environmental concerns would depend on (a) the physical and social characteristics of the respondents' neighborhoods, (b) the size of their perceived neighborhoods, (c) the length of residence at their localities, (d) educational level and attitudes toward environmental moral responsibility (and the interaction between them), and (e) the level of reported environmentally friendly behavior. Support was gained for all hypotheses except length of residence and the role of general moral attitudes toward the environment. It is concluded that to explain community action at the regional level, it is important to include both spatial and psychological insights and methodologies in research.

Recently, the behavior of senior travelers has become an important area of interest because of its market size and potential for growth. This study describes a study profiling senior travelers according to their demographic and psychographic characteristics. Six market segments were used to highlight the differences that exist in terms of holiday attractions, travel motivations, and information sources used among senior travelers when planning and choosing a holiday. Seniors are shown not to be a uniform conservative market, which has implications for marketing and product development.
