The last picture show? Timing and order of movie distribution channels

Abstract: Movies and other media goods are traditionally distributed across distinct sequential channels (e.g., theaters, home video, video on demand). The optimality of the currently employed timing and order of channel openings has become a matter of contentious debate among both industry experts and marketing scholars. In this article, the authors present a model of revenue generation across four sequential distribution channels, combining choice-based conjoint data with other information. Drawing on stratified random samples for three major markets—namely, the United States, Japan, and Germany—and a total of 1770 consumers, the empirical results suggest that the studios that produce motion pictures can increase their revenues by up to 16.2% through sequential distribution chain timing and order changes when applying a common distribution model for all movies in a country and that revenue-optimizing structures differ strongly among countries. Under the conditions of the study, the authors find that the ...

Good deeds and misdeeds: A mediated model of the effect of corporate social performance on organizational attractiveness

Abstract: Previous research has suggested that corporate social performance is positively related to firms’ attractiveness as employers. The authors propose and test an alternative model whereby job applicants’ familiarity with employers mediates the relationship between corporate social performance and organizational attractiveness. Applicants’familiarity with firms may serve as a signal of firms’suitability as employers, with more familiar firms considered more attractive. Furthermore, a firm’s overall level of corporate social activity (whether “good deeds” or “ misdeeds”) may contribute directly to firm familiarity and indirectly to attractiveness through familiarity. The authors’ results support this model; firm familiarity completely mediates the relationship between corporate social performance and organizational attractiveness.

Channel adjustments of the lower Trinity River, Texas, downstream of Livingston Dam

Abstract: Channel cross-sectional changes since construction of Livingston Dam and Lake Livingston in 1968 were studied in the lower Trinity River, Texas, to test theoretical models of channel adjustment, and to determine controls on the spatial extent of channel response. High and average flows were not significantly modified by the dam, but sediment transport is greatly reduced. The study is treated as an opportunistic experiment to examine the effects of a reduction in sediment supply when discharge regime is unchanged. Channel scour is evident for about 60 km downstream, and the general phenomena of incision, widening, coarsening of channel sediment and a decrease in channel slope are successfully predicted, in a qualitative sense, by standard models of channel response. However, there is no consistent channel response within this reach, as various qualitatively different combinations of increases, decreases or no change in width, depth, slope and roughness occur. These multiple modes of adjustment are predicted by the unstable hydraulic geometry model. Between about 60 km and the Trinity delta 175 km downstream of the dam, no morphological response to the dam is observed. Rather than a diminution of the dam's effects on fluvial processes, this is due to a fundamental change in controls of the fluvial system. The downstream end of the scour zone corresponds to the upstream extent of channel response to Holocene sea level rise. Beyond 60 km downstream, the Trinity River is characterized by extensive sediment storage and reduced conveyance capacity, so that even after dam construction sediment supply still exceeds transport capacity. The channel bed of much of this reach is near or below sea level, so that sea level rise and backwater effects from the estuary are more important controls on the fluvial system than upstream inputs.

Interleukin-6 Expression After Repeated Bouts of Eccentric Exercise

Abstract: Plasma interleukin-6 (IL-6) is known to increase in response to eccentric exercise due to an acute-phase immune response. However, the severity of muscle injury is reduced with repeated bouts of eccentric exercise, possibly as a result of decreases in plasma IL-6. This study determined the response of IL-6 mRNA and IL-6, troponin-I (sTnI), muscle strength, and soreness as a result of repeated bouts of eccentric exercise. Eight males underwent two eccentric exercise bouts (3 wk apart) involving 7 sets of 10 repetitions at 150 % of the isotonic 1-RM of the dominant knee extensors. Blood samples were taken before, after and 2, 4, 6, 24, 48 and 96 h post-exercise. Strength and soreness ratings were assessed before and at 24, 48 and 96 h-post. Data were analyzed with 2 x 4 and 2 x 8 ANOVAs and the non-parametric Friedman test (p < 0.05). Both IL-6 mRNA and IL-6 underwent peak increases (p < 0.05) at 4 h-post and 6 h-post, respectively, but were not different between bouts. However, there were significant changes (p < 0.05) in sTnI, strength, and soreness that were greater after the first bout than the second, characteristic of the repeated bout effect. These results indicate that changes in sTnI, strength and soreness were less with the second eccentric exercise bout whereas the changes in both IL-6 mRNA and protein were not effected between bouts.

Evaluating Animal-Assisted Therapy in Group Treatment for Child Sexual Abuse

Abstract: This study evaluates and compares the effectiveness of three group interventions on trauma symptoms for children who have been sexually abused. All of the groups followed the same treatment protocol, with two of them incorporating variations of animal-assisted therapy. A total of 153 children ages 7 to 17 who were in group therapy at a Child Advocacy Center participated in the study. Results indicate that children in the groups that included therapy dogs showed significant decreases in trauma symptoms including anxiety, depression, anger, post-traumatic stress disorder, dissociation, and sexual concerns. In addition, results show that children who participated in the group with therapeutic stories showed significantly more change than the other groups. Implications and suggestions for further research are discussed.
