In this article, we build on Stigler and Becker’s (1977) “consumption capital theory” and propose a novel conceptualization of film quality for the analysis of motion picture franchises. Generally, this theory predicts that the utility consumers derive from a particular good or service increases with prior consumption. We test our theoretical conjectures by drawing on the population of sequels that were running in the US between 1992 and 2011. The empirical results point to the explanatory power of the proposed framework. Film executives may use our findings to improve the profitability of their sequel productions. From a theoretical point of view, consumption capital theory allows for a more refined analysis of sequel performance along different dimensions. Moreover, it may provide a fruitful basis for the analysis of other serial media content, including books, TV, music, and games.  相似文献

ABSTRACT

This article explores some of the key impacts that Google and new technologies such as Web 2.0 have had on the way people see information and information professionals and presents the argument that much of what is typically seen as negative about Google is, in fact, positive.  相似文献

Hurricane Katrina exposed to the world the side of America that is often ignored or forgotten—the side of America where people live in poverty and struggle to meet their most basic needs. This article focuses primarily on children in Mississippi and highlights the effect that poverty has on children’s well-being at an early age and future academic success. It also provides evidence for the importance of funding high-quality pre-k programs and parental training to ensure they begin the process of preparing their children for success, not only in Mississippi but in the other states that are leaving their children behind. Finally, with the reauthorization of No Child Left Behind in 2007, recommendations are made for refocusing the premise of the law from accountability and high stakes testing to meeting the needs of all children so they can truly be successful in school.  相似文献

THIS LIMITED REVIEW of research on the social integration of children with disabilities in mainstreaming programs showed that there are several factors which may explain the apparent inconsistencies within the research literature. The diverse groups of individuals involved necessitate that attention be paid to pertinent variables and that care must be taken when findings are generalized to other groups of children with disabilities. An issue of particular concern was the simplistic measuring techniques employed in some research, particularly where studies relied on a single technique such as sociometry. There is limited evidence to support the increased use of multivariate statistical procedures as a means of producing more consistent findings. While most studies reviewed did not incorporate special treatments, that is other than integrated settings, invariably such treatments produced positive outcomes. Studies involving research designs which used the social acceptance of normal children as the basis for assessing social integration frequently resulted in negative findings.  相似文献

In 2004, a professional delegation of multicultural educators visited the People's Republic of China to explore how diversity issues are addressed and how students are prepared for entry into the international workforce. The delegation, sponsored by the People to People Ambassador Programs, observed numerous parallels to the American system of education, including the challenge of providing equity for students of minority cultures, especially those in poor rural areas, and the conflict between modernization and preservation of cultural heritage.  相似文献

This paper describes differences in mathematical problem-solving performance of third-grade gifted and fifth-grade average students observed during an eight week period. Results indicated that such factors as attitude, motivation, and belief systems were important to performance. In addition there were major differences in problem-solving behavior between the girls and boys in this study. Because these results were incidental to the original questions of the study (Buchanan, 1984), they were deemed especially significant. Four groups, one of third-grade gifted boys, one of third-grade gifted girls, one of average boys and one of fifth-grade average girls met with the experimenter twice a week for eight weeks to solve a variety of mathematical problems. In the global analysis of video tapes of all sessions and post hoc statistical analysis of selected quantifiable variables, differences in problem-solving performance were best described in terms of motivation, beliefs about mathematics, problem-solving strategies, and means of achieving satisfaction. In addition, the girls' groups were more ego-involved and social; they completed fewer problems and had longer solution times than the boys' groups. Further holistic research is needed to describe the complex interaction that occurs during mathematical problem solving in group situations. Then, appropriate intervention might be designed to assure that both boys and girls have an opportunity to perform at optimum levels.  相似文献

Self-Regulatory Mechanisms Governing Gender Development   总被引:5,自引:0,他引:5  
This study tested predictions about development of gender-related thought and action from social cognitive theory. Children at 4 levels of gender constancy were assessed for their gender knowledge, personal gender standards, and gender-linked behavior under different situational conditions. Irrespective of gender constancy level, all children engaged in more same-sex than cross-sex typed behavior. Younger children reacted in a gender stereotypic manner to peers' gender-linked behavior but did not regulate their own behavior on the basis of personal gender standards. Older children exhibited substantial self-regulatory guidance based on personal standards. They expressed anticipatory self-approval for same-sex typed behavior and self-criticism for cross-sex typed behavior. Their anticipatory self-sanctions, in turn, predicted their actual gender-linked behavior. Neither gender knowledge nor gender constancy predicted gender-linked behavior. These results lend support to social cognitive theory that evaluation and regulation of gender-linked conduct shifts developmentally from anticipatory social sanctions to anticipatory self-sanctions rooted in personal standards.  相似文献

Researchers from Goldsmiths College were asked to undertake an evaluation of a three year curriculum initiative introducing technology education, through a learner-centred, problem solving and collaborative approach. The program was developed in a group of high schools in the North West Province of South Africa. We visited ten schools involved in the project and ten parallel schools not involved who acted as a control group. We collected data on student capability (demonstrated through an innovative test activity) and on student attitudes towards technology (demonstrated in evaluation questionnaires and in semi-structured interviews). Collectively the data indicate that in areas of knowledge and skill and in certain aspects of procedures (most notably problem solving) the project has had a marked impact. We also illustrate that greater consideration could have been given in the project to developing skills in generating and developing ideas and in graphic communication. Gender differences are noted, particularly in terms of positive attitudes illustrated by both boys and girls from schools involved in the project. Attention is drawn to the critical impact the project has had on transforming the pedagogy of the teachers from a teacher-centred didactic model, to a learner-centred, problem solving model. Some wider implications of the successes of this project are debated.  相似文献

This study examined sleep-wake habits and subjective jet-lag ratings of 55 German junior rowers (n = 30 male, 17.8 ± 0.5 years) before and during the World Rowing Junior Championships 2015 in Rio de Janeiro, Brazil. Athletes answered sleep logs every morning, and Liverpool John Moore’s University Jet-Lag Questionnaires each evening and morning. Following an 11-h westward flight with 5-h time shift, advanced bedtimes (?1 h, P < .001, ηp2 = 0.68), reduced sleep onset latency (P = .002, ηp2 = 0.53) and increased sleep duration (P < .001, ηp2 = 0.60) were reported for the first two nights. Jet-lag symptoms peaked upon arrival but were still present after 6 days. Sleep quality improved (P < .001, ηp2 = 0.31) as well as some scales of the Recovery-Stress Questionnaire for Athletes. Participation was successful as indicated by 11 of 13 top 3 placings. Overall, the initial desynchronisation did not indicate negative impacts on competition performance. As travel fatigue probably had a major effect on perceptual decrements, sleep during travel and time to recover upon arrival should be emphasised. Coaches and practitioners should consider higher sleep propensity in the early evening by scheduling training sessions and meetings until the late afternoon.  相似文献

In this paper I explore how a woman secondary school headteacher and her colleagues talk about her gendered headship. To facilitate and contextualise the semi-structured interviews, participants were asked to categorise a range of attributes and qualities that have been seen as 'masculine' or 'feminine'. They attempted to plot their perceptions of her gendered headship on a continuum from 'extremely masculine' to 'extremely feminine' in relation to her appearance and interactions in various contexts. Their talk, as they explained and illustrated their thinking, reveals that even from a dualist starting point many have an understanding of the fluid nature of complex, subjective, gendered identities. The rejection of binary notions of gender by some participants disrupts the perpetuation of gender as a dualist concept. In particular, the headteacher forces open a space in which to consider the complexity of her own gendered headship.  相似文献
