Employee engagement in environmental behaviors is an important topic in operations management. Drawing upon stakeholder, commitment, and organizational support theories, this study creates and tests an empirical model of how store managers (i.e., supervisors) influence their direct reports (i.e., subordinates) to become engaged in environmental behaviors. Based on a dataset derived from supervisors and their subordinates who are employed at the same grocery store location across a large retail grocery chain, we test our study's nomological model and find support for the linkages proposed. Key research and managerial implications are discussed. 相似文献

The purpose of this research is to describe and analyze the residential mobility of senior citizens, between 2006 and 2011, among different residential forms in rural and metropolitan areas in the province of Quebec (Canada). A systematic analysis of residential form variability in territories that include both metropolitan and rural areas is performed. First, a typology of residential forms is proposed using a principal component analysis and a hierarchical cluster analysis on environment-related and housing variables. Second, the residential mobility of seniors among these different residential forms is analyzed. The results reveal a certain amount of residential stability among seniors, except where specific conditions are met, such as the death of a spouse or the onset of health problems limiting day-to-day activities. For those who moved, high-rise habitat areas and mixed areas with older rental apartments held the greatest attraction. However, suburban areas attracted the largest number of seniors because these areas account for a sizeable portion of the real estate market. 相似文献

Partially linear models (PLMs) are an important tool in modelling economic and biometric data and are considered as a flexible generalization of the linear model by including a nonparametric component of some covariate into the linear predictor. Usually, the error component is assumed to follow a normal distribution. However, the theory and application (through simulation or experimentation) often generate a great amount of data sets that are skewed. The objective of this paper is to extend the PLMs allowing the errors to follow a skew-normal distribution [A. Azzalini, A class of distributions which includes the normal ones, Scand. J. Statist. 12 (1985), pp. 171–178], increasing the flexibility of the model. In particular, we develop the expectation-maximization (EM) algorithm for linear regression models and diagnostic analysis via local influence as well as generalized leverage, following [H. Zhu and S. Lee, Local influence for incomplete-data models, J. R. Stat. Soc. Ser. B 63 (2001), pp. 111–126]. A simulation study is also conducted to evaluate the efficiency of the EM algorithm. Finally, a suitable transformation is applied in a data set on ragweed pollen concentration in order to fit PLMs under asymmetric distributions. An illustrative comparison is performed between normal and skew-normal errors. 相似文献

We study a particular restitution problem where there is an indivisible good (land or property) over which two agents have rights: the dispossessed agent and the owner. A third party, possibly the government, seeks to resolve the situation by assigning rights to one and compensate the other. There is also a maximum amount of money available for the compensation. We characterize a family of asymmetrically fair rules that are immune to strategic behavior, guarantee minimal welfare levels for the agents, and satisfy the budget constraint. 相似文献

Our study examines risk factors for metabolic syndrome on admission to an acute psychiatric facility and the incidence of medical referrals at discharge. Data on demographics, risk factors for metabolic syndrome, other health risk factors, medications, related diagnoses, and primary care providers and referrals were collected from 125 psychiatric patient charts. Comparison analysis was done for two groups: those with two or more risk factors for metabolic syndrome and those with less than two risk factors. Differences between groups were statistically significant for age, waist circumference, body mass index, high-density lipoprotein, triglycerides, and fasting glucose levels. Few patients were referred to their primary care provider for follow-up care. This study has clinical implications for improving assessment of psychiatric patients at risk for developing metabolic syndrome, for designing interventions to help patients adopt lifestyle changes to mitigate these risks, and for working toward fuller integration of psychiatric and primary care. 相似文献

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with different door handles by Portuguese subjects of both genders and different ages. This transversal study agreed with ethical aspects. 180 subjects of both genders pertaining to three age groups have participated. Five door handles with different shapes were evaluated. A subjective numeric rating scale of 5 levels was used to evaluate the effort. For statistical analysis it was applied the Friedman non-parametric test. The results have showed no significant differences of effort perception in door handles "A" and "B"; "A" and "D"; and "D" and "C". Door handle "E" presented the lowest values of all. In general, there's an inverse relationship between the results of biomechanical studies and the effort perception of the same task activity. This shows that door handles design influence directly these two variables and can interfere in the accessibility and usability of these kinds of products. 相似文献

The customization of a secretary workstation at a drama school was the objective of this case study. The investigation involved a 25-year-old illiterate woman with intellectual disabilities and low vision that had been been attending, for over 12 years, a state school for people with disabilities. The customization process, operationalized after a diagnosis was made, focused on environmental rearrangements, with the purpose of meeting the physical and social demands of the workstation. The results of this research are configured in an ergonomic analysis of work associated with an inventory of social skills, applied to people living directly with the participant. Preliminary evaluations indicated the degree of adjustment of labor demands to the personal characteristics of the participant in the customized job. 相似文献
