Using performance level box-office receipts from the PacificConservatory of the Performing Arts over eight years, we analyzeperformance-level demand for live theater. The disaggregated data allowsus to estimate demand at a particular venue and to characterize theseasonality of demand for live theater. We examine whether the supply ofshows matches the differentiated tastes of theater-goers at each of thethree locations and the sensitivity of demand to critical reviews andprior attendance. 相似文献

There is a growing need for qualified online instructors to teach the expanding population of online K-12 students. To meet this need, teachers must be provided learning opportunities to acquire the specific types of knowledge and skills necessary to teach online. In this systematic review of the literature, we utilize the TPACK framework to aggregate the types of knowledge and skills required to teach online and examine both the extent to which these elements are addressed in existing programs and are based on empirical research. Findings suggest that the types of knowledge and skills based on empirical research originate from few studies and that most programs address only a small subset of knowledge and skills, varying greatly without uniformity in content or learning experiences. 相似文献

The reverse-reward contingency (RRC) task involves presenting subjects with a choice between one plate containing a large amount of food and a second plate containing a small amount of food. Subjects are then required to select the smaller of the two options in order to receive the larger-magnitude reward. The RRC task is a commonly used paradigm for assessing complex cognition, such as inhibitory control, in subjects. To date, the RRC task has not been tested with pet dogs as subjects, and it may provide insights to their ability to perceive quantities of differing magnitudes. Nine dogs were tested in an RRC task involving three conditions. In Condition 1, plates of food were presented, and the dogs were allowed to consume their choice. In Condition 2, plates with different-sized symbols resembling the quantities of food in Condition 1 were presented, and dogs received food quantities of the same size as their choice (e.g., a larger-magnitude reward for selecting the plate with the larger shape). In Condition 3, the same plates were presented, but dogs received a reverse-sized quantity of food, relative to their choice (e.g., a smaller-magnitude reward for selecting the plate with the larger shape). A novel addition here to the traditional RRC task was the inclusion of a third, empty (control) plate that was present throughout all conditions, and no programmed consequences were provided when that plate was selected. Our results were consistent with the previous RRC literature: All dogs developed and maintained a preference for the larger stimulus option across conditions. The use of symbolic representations did not ameliorate performance on the RRC task. Applied implications are discussed. 相似文献

This study examined precursors and correlates of sexual intercourse patterns (e.g., earlier/later onset, persistence across time) among tenth and eleventh graders. Data regarding intercourse were collected for lifetime and for 6-month periods at 4 occasions of measurement over a 2-year span. Significant differences in behavioral (e.g., delinquency) and emotional (e.g., depression) problems were indicated via repeated-measures MANOVA analyses. Significant interactions among intercourse patterns, gender, and time on emotional and behavioral problems indicated synergistic relations. Planned comparisons indicated that the transition to the onset of sexual intercourse was associated with increases in delinquency and a slower rate of increase for school grades. Earlier onset and a more persistent pattern of sexual intercourse were associated with more childhood problem behaviors, earlier alcohol use, and higher levels of preadolescent antisocial behavior. 相似文献

This retrospective chart review study examined the factor structure of the Career Futures Inventory-Revised (CFI-R; Rottinghaus et al. in J Career Assess 20:123–139, 2012) and its utility as a career counseling outcome measure using a sample of 332 clients from a university career center. The CFI-R examines career agency and other career adaptability dimensions germane to clients’ career concerns. Confirmatory factor analysis results supported the proposed factor structure. Changes in CFI-R scale scores are reported for 116 clients who received counseling. The use of the CFI-R as an effectiveness outcome measure for individual, group, and classroom career interventions is addressed. 相似文献
