Arbeitsschutz als Führungsaufgabe - Eine kurze Unachtsamkeit oder unglückliche Verkettung von Ereignissen und schon ist es
passiert: Die Kanüle trifft das Pflegepersonal. Aber: Nadelstichverletzungen lassen sich durch die Verwendung sicherer Produkte
und Injektionstechniken reduzieren. Dabei ist die Verbesserung des Arbeits- und Gesundheitsschutzes des medizinischen und
pflegerischen Personals eine wichtige Aufgabe der Führungskr?fte. 相似文献

Research on the organization of innovation projects suggests that increased project flexibility is a common reaction to high levels of technological turbulence. However, existing definitions of project flexibility are inconsistent and sometimes unclear, and empirical evidence is limited. This article makes an important distinction between flexible project planning and flexible project specifications. A negative relationship is found between flexible project planning and innovation project performance, whereas flexible product specifications are found to contribute positively.This article also examines how technological turbulence contributes to the choice of flexible or inflexible strategies. Technological turbulence can be present in the external environment or can be internal to the firm, when radically new products are developed. The findings suggest that when businesses perceive technological turbulence in the environment they are more likely to adopt flexible approaches to innovation in an attempt to adapt to external pressures. In technologically innovative projects, product specifications are likely to remain fixed while project organization is likely to be adapted to the needs of the project.Taken together, the findings suggest that innovation projects should maintain stable organization, schedules and budgets, but stay flexible about product specifications. Vigilance with regards to external and internal conditions of technological turbulence, which may lead organizations to be more flexible in terms of project planning, is needed. 相似文献

We study a dynamic version of Meltzer and Richard's median‐voter model where agents differ in wealth. Taxes are proportional to income and are redistributed as equal lump‐sum transfers. Voting occurs every period and each consumer votes for the tax that maximizes his welfare. We characterize time‐consistent Markov‐perfect equilibria twofold. First, restricting utility classes, we show that the economy's aggregate state is mean and median wealth. Second, we derive the median‐voter's first‐order condition interpreting it as a tradeoff between distortions and net wealth transfers. Our method for solving the steady state relies on a polynomial expansion around the steady state. 相似文献

The aim of this study was to model and characterize the psychologicalprocesses that underlie the dynamics of global self-esteem and physicalself over time. Twice a day for 228 consecutive days, seven participantscompleted a short inventory (PSI-6, Ninot et al., 2001) measuring sixsubjective dimensions: global self-esteem, physical self-worth, physicalcondition, sport competence, physical strength, and attractive body.Each series was modeled by means of ARIMA procedures. The resultsshowed that a simple moving average model provided a satisfactoryaccount for the dynamics of all series. This model suggests that acombination of two opposite processes underlies the dynamics ofself-concept: preservation, which tends to restore the previousvalue after a disturbance, and adaptation, which tends to inflectthe series in the direction of the perturbation. 相似文献

Recent studies have analysed the economic benefits of belongingto high-trust networks and the biological foundations of individualtrust, but much scepticism remains regarding the precise roleof trust in economic transactions, as well as gaps between microand macro concepts of trust. This paper links individual andinstitutional trust by modelling the costs associated with accessingmarket, law and trust-based intermediation systems, and identifiesthe conditions under which one of the three systems may be moreadvantageous for rational actors, and thus more likely to emerge.The discussion concentrates on examples drawn from developmentpolicy to illustrate how the three systems operate together,and how the failing of the trust system affects the legal andmarket systems. 相似文献

After the disintegration of the Soviet Union, the problems encountered early in the reforms made it obvious that understanding the system and structure of the economy during the Soviet period was crucial for predictions and recommendations. The present study analyzes the production of the republics of the former Soviet Union, by grouping them into the regions defined by common geographical and historical conditions, and by estimation of cost functions that represent the two major theories of international trade: the Heckscher-Ohlin and Ricardo-Viner models. The estimated parameters of the cost functions allow us to draw conclusions about the achievement of cost minimization and to calculate the elasticities that represent the comparative statics of both models. As a result of the analysis, it is demonstrated that the achievement of the cost-minimization goal depends on local conditions. 相似文献

Financing constraints have been found to play an important role in several aspects of firm behavior, but no attention has been given to their effects on credit ratings. In this paper we analyze a unique and comprehensive data set for US firms rated by Fitch over the period 2001–07. We employ Fitch's market implied ratings derived from bond and equity prices. The analysis finds evidence that financial variables are more important in predicting credit ratings for firms likely to face financing constraints. We conclude that the financing constraint is an important dimension in the market implied ratings process. Our findings are of relevance to managers, investors and rating agencies seeking to understand the mechanism through which financing constraints affect credit ratings. 相似文献
