Major contributors to the obesity epidemic are societal and result from sedentary lifestyles and consumption of high-calorie diets. Previous studies suggest that food choice behavior is socially transmissible. Hence, knowledge of the impact of social influence on calorie intake is critical to improve the understanding about the outcomes of policies related to healthful diets. There is the need to analyze the influence of social networks on choosing food in a public place. Thus, we interviewed groups of food court patrons in an all-you-can-eat college dining hall. Results show individuals dining in a group with at least one obese group member are consuming more calories from high-calorie foods and fewer calories from low-calorie foods. Food-related interactions in a group influenced food consumption. Hence, dining with obese peers likely increases calorie intake. 相似文献

This study explores how supervisor career mentoring contributes to contemporary organizational career development, which strives to foster employees' promotability while strengthening their intention to stay. Specifically, we focus on the implications of career mentoring in team contexts. Applying a multilevel framework, we distinguish between individual‐level differentiated mentoring (i.e., an employee's mentoring perceptions as compared to those of other team members) and group‐level career mentoring climate (i.e., the average perception across all group members). In a workplace setting, we collected data from vocational job starters (N ranged from 230 to 290) and their company supervisors (N ranged from 56 to 68). We find that career mentoring climate positively relates to promotability, more so than differentiated career mentoring. Both career mentoring climate and differentiated career mentoring are positively related to the intention to stay. At the individual level, this relationship is mediated by job satisfaction. We discuss theoretical and practical implications of differentiated and group‐level mentoring. 相似文献

Kalyanam and Shively [1998. Estimating irregular pricing effects: a stochastic spline regression approach. Journal of Marketing Research 35 (1), 16–29] and van Heerde et al. [2001. Semiparametric analysis to estimate the deal effect curve. Journal of Marketing Research 38 (2), 197–215] have demonstrated the usefulness of nonparametric regression to estimate pricing effects flexibly. The empirical results of these two studies, however, also revealed that nonparametric regression may suffer from too much flexibility leading to nonmonotonic shapes for price effects. In this paper, we show how the problem of nonmonotonicity can be dealt with without losing the power of flexible estimation techniques. We propose a semiparametric approach based on Bayesian P-splines with monotonicity constraints imposed on own- and cross-price effects. In an empirical application, we illustrate that flexible estimation of own- and cross-price effects can improve the predictive validity of a sales response model substantially, even when price response curves were constrained to show a monotonic shape, as suggested by economic theory. We also discuss the consequences from an unconstrained estimation of price effects. 相似文献

The American current account deficit has once more become the subject of public debate. The size of the deficit is seen by some observers as the main cause of the recent decline in the exchange rate of the dollar. Can the latter be taken as confirmation of the increasing warnings that, in view of the dependence of the US economy on capital imports, adjustment processes such as a dramatic slump in the dollar exchange rate are imminent? What fundamental developments lie behind the US current account deficit, and do they give cause for significant adjustment reactions? 相似文献

Bei der Organisation ihrer Marktbearbeitungsaktivit?ten stehen Zeitschriftenverlage vor einer besonderen Herausforderung.
Sie agieren auf zwei interdependenten M?rkten: dem Lesermarkt und dem Anzeigenmarkt. Hinzu kommt, dass sich die Rahmenbedingungen
des Wettbewerbs in der Branche in den vergangenen Jahren stark ver?ndert haben. Auf Grundlage von mehr als 50 Experteninterviews
zeichnet der vorliegende Beitrag ein Bild vom Status Quo der Organisation der Marktbearbeitung in Zeitschriftenverlagen. Ausgehend
von einer Betrachtung wichtiger Marktentwicklungen wird aufgezeigt, mit welchen organisationalen Ver?nderungen die Verlage
auf das ver?nderte Marktumfeld reagieren. 相似文献

Appropriate real‐time forecasting models for the US retail price of gasoline yield substantial reductions in the mean‐squared prediction error (MSPE) at horizons up to 2 years as well as substantial increases in directional accuracy. Even greater MSPE reductions are possible by constructing a pooled forecast that assigns equal weight to five of the most successful forecasting models. Pooled forecasts have lower MSPE than the US Energy Information Administration gasoline price forecasts and the gasoline price expectations in the Michigan Survey of Consumers. We also show that as much as 39% of the decline in gas prices between June and December 2014 was predictable. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
