This paper reports the results of a study of managerial and leadership effectiveness carried out within an Egyptian public sector hospital in which concrete examples of ‘effective’ and ‘least effective/ineffective’ manager and managerial leader behaviour, as observed by superiors, peers and subordinates, were collected using the critical incident technique. These critical incidents were then content analyzed to identify a smaller number of discrete behavioural statements and criteria of effectiveness. The paper also reports the results of a subsequent comparative analysis of these Egyptian findings against equivalent behavioural criteria that emerged from studies in two different British NHS Trust hospitals. This latter multi-case/cross-nation study revealed high degrees of overlap, commonality, and relative generalization across all three organizations. The results lend strong empirical support to those who believe in ‘generic’ and ‘universalistic’ explanations of the nature of managerial and leadership effectiveness.  相似文献

The world of work has regularized the practice of people moving from one country to another to accept job assignments. Travel and relocation are stress-laden endeavours. For LGBT people, the risks can be more complicated than they are for heterosexuals. This article explores particular challenges that LGBT people face when they travel and relocate for business, both domestically and internationally. The article is contextualized with a literature review on sexual minorities and workplace issues, and uses auto-ethnographic stories of three of the authors’ lived experiences as sexual minorities relocating for professional reasons in order to examine issues related to LGBT relocation. These issues include legal, social, cultural and familial considerations. Implications and suggestions for human resource developers are presented, which include acquiring awareness around the psychological and physiological reactions to new and diverse ecologies, or ‘eco-shocks’.  相似文献

The objective of this study is to examine the impact of a short-term international experience, which is designed to address the conditions outlined in Allport’s (Allport, G.W. 1954. The Nature of Prejudice. New York: Perseus Book Group) contact hypothesis, on each of the four factors which make up cultural intelligence (CQ). A sample of 135 university students was broken up into test and control groups. The results for the test group suggest that the short-term experience ranging from 7 to 12 days within a structured study abroad service programme, including modest pre-trip preparation, found a significant increase in each of the four factors of CQ. At the same time, there was no significant change in the control group. Implications for human research development research and practice as well as limitations and suggested areas for future research are discussed.  相似文献

This article explores the inventory model with a general demand rate function in which both the Weibull distributed deterioration and partial backlogging are considered. The inventory model discussed here is based on the important finding by Wu [Wu, K.S., 2001. An EOQ inventory model for items with Weibull distribution deterioration, ramp type demand rate and partial backlogging. Production Planning and Control, 12, 787–793]. There are four parts in our research. First, we derive the analytical framework of the inventory model for a general demand rate function1 1.?Based on detailed suggestions of Professor Wafik H. Iskander, Email: . Second, for the ramp type demand, we improve Wu's model to find the criterion to guarantee the existence and uniqueness of the optimal solution. Third, we develop a new model to compensate for the missing case in Wu's article. Fourth, we combine our results to show that our findings are applicable to the ramp type demand inventory model, so that the optimal solution is independent of the demand function. Finally, some numerical examples and graphs are provided to illustrate our discovery and demonstrate the application of our analytical framework.  相似文献

Infants are attentive to third-party interactions, but the underlying mechanisms of this preference remain understudied. This study examined whether 13-month-old infants (N = 32) selectively learn cue–target associations guiding them to videos depicting a social interaction scene. In a visual learning task, two geometrical shapes were repeatedly paired with two kinds of target videos: two adults interacting with one another (social interaction) or the same adults acting individually (non-interactive control). Infants performed faster saccadic latencies and more predictive gaze shifts toward the cued target region during social interaction trials. These findings suggest that social interaction targets can serve as primary reinforcers in an associative learning task, supporting the view that infants find it intrinsically valuable to observe others’ interactions.  相似文献

Marketing practices that promote calorie-dense, nutrient-poor foods directly to children and adolescents present significant public health risk. Worldwide, calls for government action and industry change to protect young people from the negative effects of food marketing have increased. Current proposals focus on restricting television advertising to children under 12 years old, but current psychological models suggest that much more is required. All forms of marketing pose considerable risk; adolescents are also highly vulnerable; and food marketing may produce far-reaching negative health outcomes. We propose a food marketing defense model that posits four necessary conditions to effectively counter harmful food marketing practices: awareness, understanding, ability, and motivation to resist. A new generation of psychological research is needed to examine each of these processes, including the psychological mechanisms through which food marketing affects young people, to identify public policy that will effectively protect them from harmful influence.  相似文献

In a recent issue of The New Republic, Martha Nussbaum singled out Judith Butler for a particularly venomous attack. Nussbaum's criticism was very simple: good theory leads to practical political action, and Butler's theories do not. Nussbaum's criticism of Butler echoes a general criticism leveled against the emerging field of queer theory. Many advocates of sexual rights have suggested that poststructuralist approaches do not have practical political application. In this essay, the authors argue that Butler's work points to a new political pragmatism. In the past, many advocates of sexual rights have focused on essentialized notions of sexual identity. A politically pragmatic approach, informed by Butler's theories, can shift the debate so that the issue of homophobic discrimination, rather than sexual identity, becomes a primary focus of the sexual rights movement.  相似文献
