This study utilized the community structure approach to analyze newspaper coverage of posttraumatic stress (PTS) in veterans in 26 U.S. cities. The study examined whether media placed responsibility for PTS treatment on government or society through a review of 353 articles from March 20, 2003, to March 20, 2013. Researchers coded articles for “prominence” and “direction” to produce a “Media Vector” for each paper, ranging from 0.8403 to ?0.3592. Results showed that 25 of 26 Media Vectors (96%) supported government responsibility. Pearson correlations yielded nine significant findings. Results disconfirmed buffer hypotheses linking privilege with support for government responsibility (privilege defined by percentage of college educated, percentage of family income $100,000 or more, and percentage of professional/technical occupational status; r = ?.486, ?.524, ?.553, respectively, significant at the .006 level). Stakeholder hypotheses were also disconfirmed; greater percentages of age 65 and older correlated with more emphasis on government responsibility (r = .340, p = .048), whereas greater percentages of age 25 to 44 correlated with less emphasis (r = ?.342, p = .047). The only confirmed hypothesis linked percentage of age 45 to 64 with less emphasis on government responsibility (r = ?.559, p = .002). A regional finding was noteworthy: Media in the Midwest supported government responsibility more than other regions. Regression analysis revealed three variables influencing coverage most significantly: Family Income $100K+ (26% of variance), Percentage of Hispanic (8%), and Professional/Technical Occupational status (5%). It must be noted that nearly all newspapers yielded positive Media Vectors. This indicates that coverage in major cities generally favors government responsibility for veterans' PTS treatment, and Pearson correlation results may represent differences in the degree of support and demographic characteristics influencing this support. 相似文献

Whatever Happened to Drama? A Configurational–Comparative Analysis of Genre Trajectory in American Cinema, 1946–2013 下载免费PDF全文
Although usually conceived of and studied as individual types, genres are frequently combined in practice. This research examines how genres are combined in popular American films, and how the popularity of particular combinations changed between 1946 and 2013. Distinguishing between “contextual genres” (which identify a film's subject matter) and “affective genres” (which identify a film's intent), we find marked differences between the postwar and blockbuster eras of the Hollywood film industry. The blockbuster era exhibits less generic diversity than the earlier postwar era. Furthermore, the popular postwar‐era films dealt with serious subjects and were set in realistic settings. The blockbuster era replaced these with intense, nonrealistic films. We also find that the relationship between contextual and affective genres changes within industry eras, with affective genres dominating at the beginning of new periods and the popularity of contextual genres growing as the period progresses. 相似文献

Les relations entre les centres de recherche ou groupes de réflexion et leurs bailleurs de fonds sont importantes dans les théories et les discours publics abordant la question de l'orientation politique de la recherche sur les politiques publiques. Pourtant, très peu d'études examinent systématiquement ces relations à travers un ensemble de cas. Cet article, avec des méthodes comparatives et relationnelles, teste les théories élitiste, pluraliste et de terrain, en analysant des données portant sur le financement et l'orientation politique de 30 groupes de réflexion de 2000 à 2011. Les résultats démontrent que les dons provenant de l'étranger contribuent à soutenir certains groupes de réflexions conservateurs, mais ce financement demeure tout de même marginal dans l'ensemble. Au niveau national, les groupes de réflexion sont financés de manière contrastée: les groupes conservateurs sont financés principalement par des donateurs privés, alors que les groupes de réflexion centristes sont financés principalement par l'état. Depuis 2005, les liens entre l'ensemble des groupes de réflexion conservateurs, financés par des donateurs privés, sont devenus plus serrés. En revanche, les liens entre l'ensemble des groupes de réflexion centristes se sont relâchés et leur financement dépend de plus en plus de leurs propres revenus et des intérêts de leurs investissements. Ces résultats laissent planer un certain doute sur les prédictions qui découlent des théories élitiste et pluraliste et confirment en partie les suppositions de la théorie de terrain. The relationships between think tanks and their funders are central to theory and public discourse about the politics of policy knowledge, yet very little research systematically examines these relationships across cases. This article evaluates elite, pluralist, and field theories by analyzing original data on funding and politics for 30 think tanks from 2000 to 2011 with comparative and relational methods. I find that foreign donations help support some conservative think tanks, but that it is a small amount of money relative to other funding sources. Domestically, think tank funding is structured by an opposition between donor‐funded conservatives and state‐funded centrists. Since 2005, the cluster of conservative think tanks funded by private donors has become tighter, while the cluster of think tanks supported by the state has become looser and more reliant on self‐generated revenue and interest and investments. These findings cast doubt on predictions derived from elite and pluralist theories, and offer some support for field theory. 相似文献

Scheduling university examinations is often done with the objective of spreading a student's required examinations over an examination week. That is the equivalent of the problem of minimizing the number of examinations a student must take on any one day. An approach to scheduling exams which relates the problem to the classical assignment problem is discussed. The model developed is a symmetry-constrained assignment model, and the solution method requires use of a branch-and-bound algorithm. Results from application of the algorithm to six semesters of actual data are presented. 相似文献

Implications of a probabilistic “random walk” model of incremental sales response to advertising are developed for various timing patterns of advertising expenditures. Maximum likelihood procedures for assessing advertising effectiveness and for estimating a decay (forgetting) rate are developed and applied to artificial data of known configuration and are used to assess the impact over time of a brochure program on mail-order sales. Results are also compared to those from alternative models involving various lag patterns in advertising effects. 相似文献

We use a sample of CEO appointments at US corporations over the years 1992–2004 to test the 'glass cliff' hypothesis, which posits that females are appointed to leadership positions at firms that are in a precarious financial condition. Our analysis utilizes three measures of stock-price-based financial performance and two distinct control samples of appointments of males to the CEO position. We find that corporate performance preceding CEO appointments tends to favor females, implying that females (males) are appointed to the CEO position largely at times when the firm is in relatively better (worse) financial health. Disaggregating the data by appointments in up versus down markets, at high-risk versus low-risk firms, and by calendar time yield similar conclusions. There appears to be no glass cliff facing female CEOs at US firms. Our findings suggest a need for additional research to identify where and for what types of positions this phenomenon is prevalent. 相似文献

This article provides an analysis of my personal experience and research on the need for sub-Saharan African economic transformation. It contains relevant references to econometric modeling which are consistent with this analysis. After presenting the causes of African failures, ranging from the alleged role of slavery and colonization, to trade composition and relative decline, to present day problems of governance, low level of foreign investment in Africa, and mass unemployment, the article concludes with an agenda for the transformation of sub-Saharan Africa. 相似文献

Using data from 7272 adolescent US girls, we explore how girls’ race/ethnic group status affects their bodyweight, perceptions of overweight, and weight control practices. We hypothesize that a girl’s race/ethnic status influences her basic identity which in turn prompts her to adopt or reject a “drive for thinness.” After controlling for family and peer support, school engagement, family SES, maturation, and family structure, we find that girls’ race/ethnic status influences their susceptibility to the thinness ideals of mainstream culture. African American girls weigh more than Asian, Hispanic, or White girls, but at any given weight they perceive themselves as overweight and attempt to control their weight less. Asian American and White girls invest most in thinness dynamics. Some evidence also suggests girls from lower SES families are less driven to be thin. Our results affirm the utility of viewing material bodies as “situations” that are experienced and interpreted in accord with identity group relations and dynamics. 相似文献

The anthropology of development seeks to understand the complex encounter between international and national development regimes and local patterns of livelihood and being. As science and development move objects, at once material and discursive, through the networks of the social to reach “impoverished” others, local groups reach out to development actors to evaluate and appropriate their resources and accept or redirect those efforts. In a political interplay of disciplinary measures and localizing translations, development projects are re-invented, or aspects thereof refused, just as development actors strain to keep projects on track. With input from science and technology studies, this article explores the participatory, authoritative, and distributive dimensions to agricultural development in East Timor. Across four cases studies—a dairy, a greenhouse, a seed development program, and a permanent farming initiative—the politics of projects are compared and discussed within the broader context of colonial and postcolonial development. The article is based on a total of 1 year of fieldwork conducted in 2003, 2008, and 2009. 相似文献
