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

Child protection and welfare have become international issues in a globalized world. Ideas about childhood and the upbringing of children vary widely, depending upon the prevailing economic, socio-cultural, religious, and political contexts. These have had dramatic effects on the way societies value children, and the role acquired by the state in their protection and advancing their well-being. Children, however, remain at risk. They are placed at risk by the breakdown of extended family systems as a result of urbanization, and as a result of impaired functioning of some nuclear families, in the absence of kinship safety nets. Some traditional cultural practices place children at risk, especially girl children. Poverty creates risks for all children but it can create specific catastrophic risks for girls. Countries can enact visionary laws intended to protect children, but they will be ineffective against entrenched social attitudes, especially if only limited resources can be provided to implement and enforce them. This is the ultimate challenge that the world community must address if the vision of the United Nations Convention on the Rights of the Child is to be realized. 相似文献

This article examines the determinants of household gambling expenditures in Ireland and the effects of the recession on these expenditures using a large micro data-set, the Irish Household Budget Survey (HBS). Two gambling expenditures are examined, bookmaker tote betting and spending on the national lottery. Households with an older and a less educated head of household participate in and spend more on both forms of gambling while the presence of children in the households tends to reduce participation and spending in gambling. There is also evidence to suggest that households with an unemployed head of household have a higher likelihood of participation in gambling. The recession has affected the two forms of gambling in different ways. Lottery expenditures appear resilient to the effects of the recession. This is demonstrated in the estimated expenditure elasticities in particular. Bookmaker/tote expenditures have changed from a necessity to a luxury good, while lottery expenditures have increased in their necessity status. This can be explained by the fact that playing the lottery requires less time, knowledge and risk and has potentially greater benefits attached to it in comparison to bookmaker/tote betting. During a recession these factors become much more prevalent. 相似文献

Previous research suggests that parents may be less happy than non-parents. We critically assess the literature and examine parents’ and non-parents’ happiness-trends using the General Social Survey (N = 42,298) and DDB Lifestyle Survey (N = 75,237). We find that parents are becoming happier over time relative to non-parents, that non-parents’ happiness is declining absolutely, and that estimates of the parental happiness gap are sensitive to the time-period analyzed. These results are consistent across two datasets, most subgroups, and various specifications. Finally, we present evidence that suggests children appear to protect parents against social and economic forces that may be reducing happiness among non-parents. 相似文献

Recent advances in mathematical programming methods and computing technology have the potential for overcoming the many formidable barriers to the widespread solution of nonlinear spatial models. In particular, the recent public availability of the software package MINOS/AUGMENTED has major implications for both policy and theoretical research involving spatial models. In this paper, mathematical programming formulations of two highly nonlinear spatial models are provided, model solutions presented, and associated computational experience discussed. In addition, related work is discussed briefly and suggestions are advanced concerning the potential role of the package in furthering the objectives of this related work. Subject Areas: Mathematical Programming, Transportation, and Urban and Regional Planning. 相似文献

We investigate the performance of capacity-sensitive order review and release (ORR) procedures in job shop environments that have not been previously explored. Previous research has ignored the case of job shops which must perform to very tight due-dates because of time-sensitive customers. We propose and test a new capacity sensitive ORR procedure called path based bottleneck (PBB) in such environments, along with the modified infinite loading (MIL) procedure which has been shown to work well in several studies. We compare the performance of these two controlled release rules with that of immediate release rule under different conditions of capacity utilization and customer specified exogenous duedates. Our results indicate that PBB performs well in lowering total costs when due-dates are tight, while MIL is a better procedure with relatively loose to medium due-dates. We also show that in many cases, the shortest processing time (SPT) dispatching rule is a superior performer than a due-date based rule like critical ratio (CR); a conclusion which is contrary to the existing research in this area. In addition, the shop floor control policies recommended are shown to be sensitive to the cost structure of the firm. The managerial implications of this research in providing effective shop floor control in job shops operating under tight due-date conditions are also discussed. 相似文献

ABSTRACT: This paper supplements a simple one period non-shirking efficiency wage model with behavioural assumptions drawn from the social-psychological literature. A model of social interaction is developed in which the status associated with various labour market options yields implications for the shape of the non-shirking constraint and, thereby, for the number and type of labour market equilibria. The significance of such a finding for the existence of unemployment hysteresis is explored. 相似文献
