Revenue and attendance simultaneous optimization in performing arts organizations

Performing arts organizations are characterized by different objectives other than revenue. Even if, on the one hand, theaters aim to increase revenue from box office as a consequence of the systematic reduction in public funds; on the other hand, they pursue the objective to increase its attendance. A common practice by theaters is to provide incentives to customers to discriminate among themselves according to their reservation price, offering a schedule of different prices corresponding to different seats in the venue. In this context, price and allocation of the theater seating area is decision variables that allow theater managers to manage their two conflicting goals to be pursued. In this paper, we introduce a multi-objective optimization model that jointly considers pricing and seat allocation. The framework proposed integrates a choice model estimated by multinomial logit model and the demand forecast, taking into account the impact of heterogeneity among customer categories in both choice and demand. The proposed model is validated with booking data referring to the Royal Danish theater during the period 2010–2015.     

Women,torture, & spectacle on Chilean television

ABSTRACT

In the years since the fall of the civil–military dictatorships in the Southern Cone, considerable attention has been paid to first-person testimonies of human rights victims. A great number of these have been by women who narrated sexual political violence. However, while there has been work done on the relation between terror, trauma, and spectacle in postdictatorial television shows, rarely has this also included a gendered perspective. In this article we seek to open this area of discussion by evaluating the manner in which women’s televised testimonies of political sexual violence have been constructed on late night talk shows in Chile, using recent history and memory theory, as well as feminist theory on the representation of sexual violence in mass media.     

Salivary Testosterone Levels in Intellectually Gifted and Non-Intellectually Gifted Preadolescents: An exploratory study

There are suggestive data to link salivary testosterone concentrations (ST) to cognitive abilities in humans. Saliva reflects the plasma-free fraction of ST, which is biologically active, available for uptake by tissues including the brain. In the present study, therefore, salivary testosterone levels in healthy preadolescent children of both sexes, 6 to 9 years old, were determined. Among a total of 215 participants, 122 were intellectually gifted, attending special classes for gifted in primary school (IQ 130 or more in two independent standard tests of general intelligence). Their ST levels were compared with ST levels of 93 non-gifted children attending regular primary school. In general, results show there are no changes in ST concentrations between ages 6 and 9. However, there are significant differences between gifted and non-gifted participants. ST levels in gifted children were lower (p < 0.01) in all age categories. This also holds for both sexes separately (p < 0.01).     

The Benefits of Fixed Item Parameter Calibration for Parameter Accuracy in Small Sample Situations in Large‐Scale Assessments

Large‐scale assessments such as the Programme for International Student Assessment (PISA) have field trials where new survey features are tested for utility in the main survey. Because of resource constraints, there is a trade‐off between how much of the sample can be used to test new survey features and how much can be used for the initial item response theory (IRT) scaling. Utilizing real assessment data of the PISA 2015 Science assessment, this article demonstrates that using fixed item parameter calibration (FIPC) in the field trial yields stable item parameter estimates in the initial IRT scaling for samples as small as n = 250 per country. Moreover, the results indicate that for the recovery of the county‐specific latent trait distributions, the estimates of the trend items (i.e., the information introduced into the calibration) are crucial. Thus, concerning the country‐level sample size of n = 1,950 currently used in the PISA field trial, FIPC is useful for increasing the number of survey features that can be examined during the field trial without the need to increase the total sample size. This enables international large‐scale assessments such as PISA to keep up with state‐of‐the‐art developments regarding assessment frameworks, psychometric models, and delivery platform capabilities.     

Generational perceptions of promotion and tenure expectations by faculty in a striving university: A quest for legitimacy?

Striving universities seek to gain prestige in the academic market. One characteristic of striving universities is a change in the faculty reward system. In this study, we examined historical promotion and tenure criteria in five disciplinary units at one striving university and then conducted interviews with senior faculty and recently tenured faculty in each unit to better understand the striving dynamics at play. Findings demonstrated that pressures to seek legitimacy were a result of the faculty themselves, the institution’s desire to gain legitimacy through an increased research profile and the disciplinary ties outside the university.
