Human versus spatial dimensions of crowding perceptions in retail environments: A note on their measurement and effect on shopper satisfaction

Abstract: Perceived retail crowding was originally conceptualized as having two dimensions, but subsequent empirical work in marketing has treated the construct unidimensionally. This paper reports a series of lab and field studies that examine the dimensionality of the construct and its relationship to store satisfaction. Two alternative crowding measures are tested. Results suggest that perceived retail crowding has distinct human and spatial dimensions that affect satisfaction differently.

Accuracy of energy intake data estimated by a multiple-pass, 24-hour dietary recall technique.

Abstract: Objective This study examined the accuracy of a multiplepass, 24 hour dietary recall method for estimating energy intakes of men and women by comparing it with energy intake required for weight maintenance. Design Threeday, multiplepass, 24-hour recalls were obtained on randomly selected days during a selfselected diet period when subjects were preparing their own meals and during a controlled diet period when all meals were provided by the study. During the dietary intervention, weight was maintained; body weight and dietary intake were monitored closely, thereby allowing estimation of the energy intake required for weight maintenance. Subjects/setting Seventyeight men and women (22 to 67 years old) from the Dietary Effects on Lipoprotein and Thrombogenic Activity (DELTA) study participated in this study. All 24-hour recalls were collected using a computerassisted, interactive, multiplepass telephone interview technique. Energy requirements for each individual were determined by the energy content of the DELTA study foods provided to maintain weight. Statistical analysis Paired and independent t tests were conducted to examine differences among study variables. Agreement between recalled energy intake and weight maintenance energy intake was analyzed using the BlandAltman technique. Results Compared with weight maintenance energy intake, during the selfselected diet period men and women underestimated energy intake by 11% and 13%, respectively. During the controlled diet period, men underestimated energy intake by 13%, whereas women overestimated energy by 1.3%. Applications/conclusions Men had a tendency to underestimate energy intake irrespective of the recording period. The accuracy of the recalled energy intake of women may be influenced by recording circumstances. Researchers should examine the factors influencing underreporting and overreporting by individuals and their impact on macronutrient and micronutrient intakes. Also, strategies need to be developed to minimize underreporting and overreporting. J Am Diet Assoc. 2000; 100:303-308,311.

The Mortality and Medical Costs of Air Pollution: Evidence from Changes in Wind Direction.

Abstract: We estimate the causal effects of acute fine particulate matter exposure on mortality, health care use, and medical costs among the US elderly using Medicare data. We instrument for air pollution using changes in local wind direction and develop a new approach that uses machine learning to estimate the life-years lost due to pollution exposure. Finally, we characterize treatment effect heterogeneity using both life expectancy and generic machine learning inference. Both approaches find that mortality effects are concentrated in about 25 percent of the elderly population.

Introduction to Special Topic Forum Privatization and Entrepreneurial Transformation: Emerging Issues and a Future Research Agenda.

Abstract: Privatization has become a popular strategy to promote economic development in emerging, developing, and developed economies. Despite its popularity, little attention has been devoted to examination of the organizational and managerial implications of privatization or to the effect of privatization on companies' ability to innovate and engage in entrepreneurial activities. In this article the authors discuss privatization's increasing importance and present a model that links privatization to a firm's entrepreneurial activities. The authors conclude with a discussion of issues that they believe deserve scholars' attention in theory development and subsequent empirical examination.

Long-Term Effects of the Death of a Child on Parents’ Adjustment in Midlife

Abstract: The death of a child is a traumatic event that can have long-term effects on the lives of parents. This study examined bereaved parents of deceased children (infancy to age 34) and comparison parents with similar backgrounds (n = 428 per group) identified in the Wisconsin Longitudinal Study. An average of 18.05 years following the death, when parents were age 53, bereaved parents reported more depressive symptoms, poorer well-being, and more health problems and were more likely to have experienced a depressive episode and marital disruption than were comparison parents. Recovery from grief was associated with having a sense of life purpose and having additional children but was unrelated to the cause of death or the amount of time since the death. The results point to the need for detection and intervention to help those parents who are experiencing lasting grief.
