Companies are increasingly encouraging employees to use Facebook and other social media to interact with coworkers in order to empower collaboration and knowledge sharing. Yet, there is a hidden problem that has been neglected by managers. The more employees interact with coworkers through social media to facilitate their work in the organization, the more likely they are to learn about and become interested in other companies via social media, form new work connections outside the organization, and engage in job search behaviors. The use of social media to facilitate work and benefit organizations could paradoxically risk fostering withdrawal intentions and turnover, which damage organizations. This article provides evidence of this paradox from an empirical study. After having identified the problem, the article proposes both the solutions to avoid and the solutions to adopt, illustrating best practices from successful companies, comparing their benefits and costs, and indicating the situations in which each solution is best implemented. To conclude, I offer 10 recommendations to turn the problem into an opportunity and use social media as an innovative recruitment tool. 相似文献

Postponement is a well-known organizational concept and usually relates to the deferment in time of manufacturing and/or logistics operations. In the current global competitive landscape, situations where postponement can be applied are rapidly increasing. Faced with the wide range of customs duties and free-trade agreements currently in place, companies need to (re)design their postponement strategies to customize their products appropriately, and to the proper degree, in each market. As the actual location where operations take place has a major impact on a company’s overall performance, the spatial perspective must also be taken into account when designing global postponement strategies, alongside the conventional temporal perspective. Heretofore, the academic literature does not offer any comprehensive framework on a global scale either for handling what is known as the postponement boundary problem, or for conceptualizing the related postponement strategies. Building on previous research, the aim of the present study was to investigate the postponement concept in a global environment with a downstream focus. The intended purpose is twofold: first, to review and expand previous studies on the subject and, second, to provide some guidelines for conceptualizing global postponement strategies. A structured literature review was first conducted, followed by the development of a framework that combines both the temporal and the spatial dimensions. Finally, the framework was applied to a group of 28 business cases taken from the literature, to act as a bridge between academic theories and practitioners’ current business operations. 相似文献

I provide an alternative explanation for why societies exhibit varied environmental behaviours. I use a Kantian moral approach at a microeconomic level. I show that two identical societies (in terms of income level and political system) might follow different paths with respect to their “green” behaviour. Additionally, I identify tipping points that could nudge a society from a polluting behaviour to a green one. I find that the perception of environment within the society can be an important factor in this shift. 相似文献

As a result of the financial crisis, ethical banking has become a visible phenomenon that has aroused the interest of those clients that are disappointed with conventional banking, as well as that of the scientific community. However, research on ethical banking has just started, with several subjects pending consensus, such as the proper definition or identification of banks considered to be ethical. In view of the above, the objective of this study is, first and foremost, to define the common characteristics of all banks affiliated to the movement; empirically, we shall quantify the level of commitment with the same and, thus, as a result of this quantification, obtain a ranking that classifies the selected banks according to the scores obtained. Regarding the methodology used, the quantification of the level of commitment with ethical banking is done through a new index called SEBI (Social and Ethical Banking Index), designed from the characteristics defined in the study and applied to the banks identified as ethical due to being a part of the main network of this type of banking: The Global Alliance for Banking on Values (GABV). 相似文献

ABSTRACTThis article explores the relationships among employee moral efficacy, coworker emotional support, coworker instrumental support, and employee voice behavior regarding abusive supervision in the hospitality industry in Ecuador: a high power distance culture. The results indicate that employees’ moral efficacy predicted their voice behavior with regards to abusive supervision and that coworker emotional support strengthened this relation. However, an interaction effect between moral efficacy and coworker instrumental support on voice behavior was not found. This study provides a theoretical extension of the voice literature by introducing the roles of moral efficacy and coworker support, and has practical implications for the hospitality workplace. 相似文献

This paper develops an estimation and testing framework for a stationary large panel model with observable regressors and unobservable common factors. We allow for slope heterogeneity and for correlation between the common factors and the regressors. We propose a two stage estimation procedure for the unobservable common factors and their loadings, based on Common Correlated Effects estimator and the Principal Component estimator. We also develop two tests for the null of no factor structure: one for the null that loadings are cross sectionally homogeneous, and one for the null that common factors are homogeneous over time. Our tests are based on using extremes of the estimated loadings and common factors. The test statistics have an asymptotic Gumbel distribution under the null, and have power versus alternatives where only one loading or common factor differs from the others. Monte Carlo evidence shows that the tests have the correct size and good power. 相似文献

Lateral transshipment has been studied lately as a promising policy for increasing the performances of multi-echelon spare parts inventory system. By lateral transshipment spare parts can be moved from one location with excess inventory to another location, at the same echelon, in shortage, with the aim of reducing supply delays of spare parts. This paper will examine the relative effectiveness of two lateral shipments approaches in reducing the mean supply delay (MSD) of a non-repairable item, with respect to a classical policy of no lateral shipments. A simulation model of a two echelon supply network has been implemented and an experiment has been performed by varying different parameters of the supply network, such as the number of warehouses (locations at the lower echelon), the supply lead time from the central depot, the spare parts demand uncertainty, and the size variability of the warehouses. Results show appreciable reductions of MSD when lateral shipments are allowed with respect to the classical policy, in almost every network configuration. 相似文献

This research investigates the relationship between Web site design and the Web site end-user experience of a vast number of English tourism destinations, both local and regional ones. Following recent research in the field, this paper evaluates destinations’ online communication based on the implemented Web site features and on the effectiveness of the communication itself, borrowing its research methodology from different domains. After content and functionality analysis, a user-experience, scenario-based investigation has been carried out, which demonstrated that complex Web sites do not always serve end-users’ needs properly; in other words, Web site complexity is not directly related with good user experience. This research may help destination managers to foster their online communication if they have fewer content and functionalities but are better focused and clearly user-oriented. 相似文献

In this paper we use a continuous-time general equilibrium model to analyze the problem of evaluating new irreversible investment
opportunities that take the form of technological changes. Being a new technology, by definition, not perfectly correlated
with the existing ones, the traditional spanning assumption invoked by the Real Option literature is not applicable in this
context and a general equilibrium approach provides a more suitable framework. We analyze the problem of optimal consumption
and investment of the representative individual in the context of the Cox Ingersoll and Ross (1895) model. We characterize
the solution of the model under different assumptions about the utility function of the representative individual and about
the parameters describing the technologies in the economy. A major result obtained from the model is the possibility of jumps
in the equilibrium rate of return at the time in which technological changes are implemented. This is particularly interesting
considering the fact that such jumps are obtained endogenously from the solution of the optimization problem and not imposed
by “ad hoc” assumptions on the evolution of some variables.

Riassunto Un modello di equilibrio economico generale in tempo continuo è utilizzato per analizzare il problema di valutare una nuova, irreversibile, opportunità di investimento che si presenta sotto forma di innovazione tecnologica. Essendo, per definizione, la nuova tecnologia non perfettamente correlata con le tecnologie esistenti, la letteratura delle “opzioni reali” non è applicabile ed un modello di equilibrio economico generale fornisce un ambiente più adatto allo studio del problema. Facendo uso del modello di Cox Ingersoll and Ross (1985) si fornisce una soluzione sotto diverse ipotesi riguardanti la struttura delle preferenze e la natura dell'innovazione tecnologica. Un interessante risultato è la derivazione di possibili discontinuità nel tasso di interesse di equilibrio in corrispondenza dell'adozione della nuova tecnologia.
