Managers predict the sales of new entertainment products prior to their release using comparables, such as similar books from the same author or movies with the same actors. In this study, the authors analyze whether diffusion models for media products provide helpful support in the management task of predicting prelaunch sales of the first distribution channel for three different product categories. They compare the performance of predictions based on (a) simple success factor regressions (OLS) and (b) diffusion models against real management predictions. Based on samples covering the German music, film, and the literary market, we show that model-based forecasts outperform the forecasts of management teams for the majority of the products. In contrast, management is superior in forecasting top sellers. This is due to unobserved factors arising from more management attention attached towards super stars. The authors do not find substantial prediction differences between simple success factor regressions and more complex diffusion models. Thus, managers interested in total sales estimates can easily rely on OLS based success factor predictions. Advertising and product differentiation factors with respect to quality (e.g., star power, critics, or country of origin) are across all 3 industries highly relevant for sales predictions, whereas others variables (e.g., price, distribution power, season, or competition) differ across industries. 相似文献
ABSTRACTThis article describes a program session about licensing electronic resources. The speakers discussed a range of licenses in the current electronic resources landscape and described current trends in the negotiation and management of licenses. They also explored the impact of workflow design on the accessibility of electronic resources at any institution. 相似文献

How can school mathematics prepare citizens for a democratic society? Answers to this question are not static; they change as society and its problems change. The SARS-CoV-2 pandemic with its corresponding disease COVID-19 presents such a problem: what is needed to navigate this complex situation that involves, among other things, mathematics? Using the essay genre, we use three narratives from three countries—Italy, the USA (California), and Germany—to reflect on the goals of teaching mathematics during this crisis and examine aspects of each country’s standards for mathematics education. These three stories are framed by the authors’ backgrounds, experiences, interests, their country’s situation, and response to the pandemic. We first present the three narratives and then examine common issues across them that might provide insights beyond this current crisis, for preparing students to become active citizens. In particular, we focus on three issues: (1) developing a positive mindset toward mathematics to engage with and reflect on real-world problems, (2) improving interdisciplinary connections to the sciences to better understand how science professional practices and insights are similar or different from everyday practices, and (3) considering interpersonal and collective matters beyond the individual.

ABSTRACTSchools have a key role in promoting student social and emotional development and are encouraged to serve as a primary source of support, especially for those learners in need of special attention for addressing their needs. Young people’s subjective emotional-social well-being is a general indicator of their mental health status. In this article, we present an assessment of the emotional, psychological and social well-being of Greek adolescent students, determine whether they are flourishing or languishing and investigate whether well-being varies by gender, age and year level. Analysis of data from over 500 Greek adolescent students (year levels 6–10) who completed the Mental Health Continuum (MHC) scale indicated that over half of the participants were flourishing, while only a small proportion were languishing and the remainder had moderate mental health. Gender differences were identified with female students reporting more challenges to their well-being than their male peers. Additionally, younger students were more likely to be flourishing than older students. 相似文献
