Competitive pressure, high development costs, long lead times, rapidly changing technologies and the risks inherent in projects combined with the delays seen in the latest aircraft models (with the rise in costs that these have entailed) highlight the need to reorganise the supply chain in the aeronautics sector paying special attention to an improvement in inter- and intra-organisational integration. The aim of this study is to analyse the situation of supply chain integration (SCI) in the aeronautics sector using three dimensions (information integration, coordination and resource sharing and organisational relationship linkage), considering both internal integration and external integration with customers and suppliers. A group of first-tier supplier experts analyse the dimensions and assess the degree to which the factors that define SCI have been achieved. The results enable strengths and weaknesses to be determined and indicate possible improvements to the situation that is detected with clear managerial implications. 相似文献

The number of individuals with Alzheimer's disease or a related dementia is growing at a staggering rate. Thus, it is essential that social workers in geriatric settings are knowledgeable about this disorder and the appropriate interventions to use at all stages of the disease. The purpose of this article is to examine the types of non-pharmacological, psychosocial treatments that are used to manage the behavioral manifestations and changes in the mood of individuals with Alzheimer's disease or a related dementia. While great strides have been made in pharmacological treatments of Alzheimer's disease, less attention has been given to the types of psychosocial interventions that are readily employed in community-based and long-term care settings to assist in the care of these individuals. This article provides an overview of psychosocial interventions, as well as identifies the direction for future evidence-based treatment studies, for individuals with Alzheimer's disease and related dementia. 相似文献

We exploit Bayesian criteria for designing M/M/c//r queueing systems with spares. For illustration of our approach we use a real problem from aeronautic maintenance, where the numbers of repair crews and spare planes must be sufficiently large to meet the necessary operational capacity. Bayesian guarantees for this to happen can be given using predictive or posterior distributions. 相似文献

AbstractGrowing dependence on suppliers for production and innovation, together with increasing consumer demands, has prompted recent discussions of the importance of purchasing–marketing functional integration. However, empirical studies are needed to understand how to manage this interface within a new product development (NPD) context. This study, grounded in information processing theory, proposes a new model to classify integrating mechanisms as either information-sharing forums or optimizers. This model further postulates the greater capacity of optimizer mechanisms for improving NPD commercial and financial performance, as well as speed. The empirical results, obtained from a sample of 141 firms, show that forums only improve NPD speed, whereas optimizer mechanisms evoke better commercial and financial performance. This study therefore highlights the potential of different integrating mechanisms and contributes to the on-going debate about the very concept of functional integration itself. 相似文献

The aim of this article is twofold: to demonstrate the actuarial imbalance in the Spanish pension system in its current form; and to measure the degree of aggregate economic risk to which pensioners are exposed when applying formulas for the calculation of retirement pensions based on notional accounts. The model used generates scenarios for various periods encompassing some 10,000 different permutations of the macroeconomic indices needed to calculate such parameters as initial pension, earnings replacement rate, or internal rate of return and value at risk. The findings are analysed both objectively and subjectively. The main conclusions are that if the projections for the macroeconomic indices used bear only a minimal resemblance to reality, the pension system will accumulate further financial imbalance in the future that will force it either to reduce initial pensions considerably or to make some radical adjustments to the parameters. In terms of risk, for beneficiaries with high risk aversion the preferred formulas would be those based on future variations in wages with a constant pension amount in real terms; on the other hand, those less averse to risk would prefer formulas that generate a smaller initial pension but one which grows in real terms with subsequent changes in wage levels. 相似文献

The present study integrates theory and researchon power, politics, and social constructionism toinvestigate how human resource (HR) departments inorganizations gain influence. Survey results from 242 organizations demonstrated that symbolicactions are stronger predictors of HR department powerthan unionization, HR performance, and top managementattitudes. Implications of the results are discussed as are directions for futureresearch. 相似文献

A modification of the proportional solution for bargaining problems with claims is proposed. This solution is constructed
by considering an endogenous reference point. Characterization results of the aforementioned solution are provided.

We consider the problem of allocating a finite set of indivisible goods and a single infinitely divisible good among a group of agents, and we study a solution, called the Identical Preferences Lower Bound solution, in the presence of consistency properties. This solution is not consistent. We prove that its maximal consistent subsolution is the No-envy solution. Our main result is that the minimal consistent extension of the intersection of the Identical Preferences Lower Bound solution with the Pareto solution is the Pareto solution. This result remains true in the restricted domain when all the indivisible goods are identical, but not when there is a unique indivisible good.This paper was developed during my stay at Rochester University in the summer of 1992. I would like to express my special thanks to Professor William Thomson for all his help and advice. Iam also grateful to my supervisor Luis Corchón, to Koichi Tadenuma and to the anonymous referees for their helpful comments. The remaining errors are my exclusive responsibility.

Abstract The relationship between three different performance measures and burnout was explored in 20 Dutch Intensive Care Units (ICUs). Burnout (i.e. emotional exhaustion and depersonalization) proved to be significantly related to nurses' perceptions of performance as well as to objectively assessed unit performance. Subjective performance measures relate negatively to burnout levels of nurses, whereas an objective performance measure relates positively to burnout. Furthermore, subjectively assessed personal performance (i.e. personal accomplishment) is more strongly related to burnout than subjectively assessed unit performance. A model test of the relationship between both types of subjective performance and burnout reveals that nurses' perception of unit performance is indirectly related to burnout through perception of personal performance. This model holds similarly for objectively well- and poor-performing ICUs. 相似文献

The aim of this qualitative study is to identify the dimensions people used to assess the risk of smoking and then compare them with those used by health professionals in primary healthcare. Five discussion groups were conducted. The field work was carried out in Barcelona (Spain), from February 2005 to January 2006. Data were analyzed following a semantic‐thematic categorical content analysis (ACC‐ts). Results showed that people tend to employ stereotypical discourses when evaluating the risk of smoking. Similarly, they reassess the risk in the context of their life experience and incorporate new nuances to the arguments sustaining their behavior. Once this reassessment takes place, the decision to continue smoking emerges, and smokers come up with additional arguments justifying their habit (i.e., age, benefits related to costs). Professionals are aware of this process and its multidimensional nature. Nevertheless, their discourse loses this multidimensional feature when discussing the strategies they use at smoking cessation interventions. This qualitative study increases the understanding of various meanings that people attribute to their life experience. These assumptions may be useful for developing health practices that are closer to people. As a practical utility of these results, it would be interesting to apply a preliminary assessment of the different meanings that people attribute to smoking from their life context in risk communication. 相似文献
