Strong, effective communication may be the single most important key to success for any type of executive. Leaders of health care organizations must be able to promote ideas that others will implement, help staff see the value of their work, and have the vision to overcome limitations that stand in the way of progress.  相似文献

Leadership — an underestimated profession. From a greenhorn of leadership to a qualified manager The author presents an empirical inquiery, basing on interviews with 10 recently appointed managers. She demontrates, that managers hardly ever are prepared for her job in advance. This may lead to several problems, up to a demotivation of all persons envolved. The author proposes a procedure of personal development with three elements: seminars to impart knowledge, employment of internal mentors and of external coaches.  相似文献

This simulation study compares three operational measures of performance through the exploration of three work-in-process (WIP) inventory drive systems and their associated inventory buffer characteristics. The three drive systems under study are a push, a pull and a hybrid push-pull system. While these systems have many aspects in common, their buffer management systems do not. The data analysis was based on information gathered from three computer-simulated flow shop assembly lines all operating in the same environment. Hypotheses concerning the operational performance measurements were established, independent variables were controlled and manipulated and a conclusion was drawn as to which system would afford the operation optimum results. While inventory has traditionally been considered and is currently being shown as an asset from an accounting point of view, it is obvious from the findings of this study, that excess WIP inventory, above the minimal requirements for production, may have a negative effect on the operational measurements evaluated.  相似文献

In this paper it is argued that although labelling can lead to stigmatisation, this is not always the case. Evidence is presented to demonstrate that stigmatisation can take place in the absence of formal labelling or stigmatisation can precede labelling. Most of the evidence presented is from two interview studies one with 27 children and the other with 16 adults. It is suggested that further deconstruction of the labelling process is necessary, and that factors such as whether labels are formal or informal, private or public need to be taken into account. Finally, it is proposed that labelling can be considered at many levels of analysis from the personal to the political and that a coherent framework that integrates these different levels of analysis is needed.  相似文献

We describe a quasi-experimental trial of time-limited family therapy with veterans and families of veterans who served in Europe, outside the war zone, during Operation Desert Storm (ODS). Family systems therapy was provided both to individuals and conjointly to couples or families during the acute postwar readjustment period. The intervention adapted strategies from structural, strategic, intergenerational, and behavioral family therapies in a brief-treatment protocol for systemic stressor resolution. Veterans given family system therapy were able to resume functional levels of psychosocial adjustment and reduce the risk of long-term (Chronic or delayed) psychosocial impairment. Based on these preliminary findings, controlled evaluation of family systems therapy appears warranted for indi-  相似文献

Each day for five days, 79 fifth‐grade children reported on events that occurred at school and they and their parents described their interactions with each other each evening. Consistent with previous research, it was found that on days when children reported more academic or peer problems during the day at school, they later described more aversive interactions with their parents. As hypothesized, increases in anxiety and drops in children's state self‐esteem partially mediated this link. However, parents did not report any differences in their interactions with the target child on days when the child experienced problems at school. This study suggests that negative events experienced by children while at school lead to short‐term changes in mood and self‐esteem, which influence their perceptions of subsequent interactions at home with parents.  相似文献

Protecting riparian corridors is a commonly applied environmental policy in urban landscapes. However, empirical data demonstrating their efficacy for biodiversity conservation outcomes is scarce. In this study we investigated whether riparian corridor width influences the diversity and community structure of ant (Hymenoptera: Formicidae) and vascular plant assemblages therein. Eighteen corridors of differing widths were selected from within the Ku-ring-gai Local Government Area, Sydney Australia. Ants were sampled using pitfall traps positioned within rectangular vegetation transects (30 × 10 m). Both ant and plant species richness, when standardised for sampling effort, were unrelated to riparian corridor width. However, significant compositional differences between sites were evident with increased width up to ~50 m. Narrow corridors contained greater abundances of opportunistic ant species and higher proportions of exotic plants. We interpret this to be the result of the greater disturbance/edge influence derived from adjacent upland urban environments. Site beta diversity did not increase with corridor width, suggesting that the exclusion of novel upslope habitats in narrow riparian corridors is not a significant cause of community assemblage modification at these sites. To minimise the impact of deleterious edge effects on ant fauna, environmental managers should seek to retain riparian corridors wider than ~50 m. However, we observed substantial between-site variability of biotic assemblages, irrespective of corridor width. Therefore we recommend that environmental management practice needs to take a catchment-wide approach and consider other parameters that may contribute to riparian health so as to optimise the protection of riparian biodiversity.  相似文献

Formalized planning is currently applied to planning for operations and capital investment, planning for products and markets, and occasionally for manpower. However, there is little evidence that companies are producing formal plans and programmes to deal with social and political change. Unfortunately, public opinion is moving against business, action groups inside and outside companies are challenging the authority of management, and public officials and politicians are already framing new laws and regulations. Unless managers begin to get more involved in the framing of these controls they are likely to find laws enacted and enforced by people who have little knowledge or sympathy with business. In this article the author points up the necessity to assess the social and political challenge to their business, and formulate and implement social and political strategies and plans aimed at ensuring the survival and prosperity of their organisations.  相似文献
