This paper highlights the interaction between intended human resource (HR) practices as perceived by supervisors and status similarity between supervisors and employees as a key source of variation in employee work engagement among 298 employees reporting to 54 supervisors at a luxury Chinese hotel. Using a multi-level, process-oriented approach to examine the relationship between intended HR practices by supervisors and engagement as perceived by employees, we show (1) that the interaction of supervisor perceptions of HR practices and supervisor–subordinate hukou (place of origin) status similarity is positively related to employee reports of Leader–member exchange (LMX), HR practices and work engagement; (2) that the interaction of supervisor perceptions of HR practices and hukou status similarity influences employee perceptions of HR practices through LMX; and (3) that the interaction of supervisor perceptions of HR practices and hukou status similarity influences work engagement through employee perceptions of LMX and HR practices. Theoretical and practical implications are discussed. 相似文献

When applied to solving real-world problems in the public sector, managerial techniques are likely to evolve over time in response to the context of their implementation. The temporal dynamics of this evolution and its underlying processes, however, remain under-researched. To address this gap, we present a qualitative longitudinal case study of a UK-based knowledge mobilization programme utilizing “facilitation” as a service improvement approach. We describe the processes underpinning the distortion of facilitation over time and argue that an uncritical and uncontrolled adaptation of managerial techniques may mask the unsustainable nature of the resulting improvement outcomes captured by conventional performance measurement. 相似文献

We propose a valuation method for financial assets subject to default risk, where investors cannot observe the state variable
triggering the default but observe a correlated price process. The model is sufficiently general to encompass a large class
of structural models and can be seen as a generalization of the model of Duffie and Lando (Econometrica 69:633–664, [2001]). In this setting we prove that the default time is totally inaccessible in the market’s filtration and derive the conditional
default probabilities and the intensity process. Finally, we provide pricing formulas for default-sensitive claims and illustrate
in particular examples the shapes of the credit spreads.

We consider a model for interest rates where the short rate is given under the risk-neutral measure by a time-homogeneous
one-dimensional affine process in the sense of Duffie, Filipović, and Schachermayer. We show that in such a model yield curves
can only be normal, inverse, or humped (i.e., endowed with a single local maximum). Each case can be characterized by simple
conditions on the present short rate r
t
. We give conditions under which the short rate process converges to a limit distribution and describe the risk-neutral limit
distribution in terms of its cumulant generating function. We apply our results to the Vasiček model, the CIR model, a CIR
model with added jumps, and a model of Ornstein–Uhlenbeck type.

We analyze the two goals behind the European Bologna process of increasing student mobility: enabling graduates to develop
multi-cultural skills and increasing the quality of universities. We isolate three effects: (1) a competition effect that
raises quality, (2) a free-rider effect that lowers quality, and (3) a composition effect that influences the relative strengths
of the two previous effects. The effects lead to a trade-off between the two goals. Full mobility may be optimal only when
externalities are high. In this case, student mobility yields inefficiently high educational quality. For moderate externalities,
partial mobility is optimal and yields an inefficiently low quality of education.

We present a dual-process risk perception model that integrates cognitive and emotional as well as consequentialist and deontological components by distinguishing between two modes of evaluative processing: (a) a consequentialist evaluation that focuses on potential consequences and (b) a deontological evaluation that focuses on moral values. Each of these two modes is assumed to trigger specific cognitive evaluations, specific emotions, and specific behavioral tendencies concerning a perceived risk. We conducted an experiment (N = 270) that tested whether the relative dominance of the two evaluative modes would depend on the causal structure of the environmental risk being evaluated and on the social role of the evaluator. Three types of causal structure were varied by providing scenario information: (a) anthropogenic risks that endanger only nature, (b) naturally caused risks with potential harmful consequences for humans, and (c) anthropogenic risks that may harm humans. Participants evaluated each scenario from the perspective of one of three social roles: mayor, expecting parent, and environmental activist. For each scenario, participants specified their focus and evaluated the event’s morality and perceived risk, the intensity of specific emotions, and their preferences for prospective behaviors. Results showed that the consequentialist evaluation was generally stronger than the deontological evaluation and was less affected by the experimental manipulations. The deontological evaluation was substantially affected by the risk’s causal structure. It was stronger for anthropogenic than for natural causation; risks caused by humans were associated with greater perceived moral blameworthiness, more intense morality-based emotions (e.g. outrage), and a stronger tendency to perform agent-related behaviors (e.g. aggression) than naturally occurring risks. The effect of the social role was less pronounced than that of the causal structure. Furthermore, the effect of an evaluative focus on behavior was fully mediated by emotions for deontological evaluations and partially mediated for consequentialist evaluations. The implications for environmental risk perception and communication are discussed. 相似文献

为了维持长期的竞争优势,企业需要不断进行技术创新和产品创新。如何在有限的研发资源下使创新项目组合的绩效最大化是企业进行创新管理中面临的主要问题。本文从创新项目组合的战略一致性、平均项目绩效和业务协同3个指标来度量创新项目组合管理绩效,并从流程和管理者的视角研究其关键影响因素。通过实证研究发现,高管参与和项目组合管理流程的设计与实施对项目组合的战略一致性有显著的正向影响;高管参与、项目经理胜任力和项目终止质量对平均项目绩效有显著正向影响;项目经理胜任力、项目组合管理流程的设计与实施和项目中止质量对业务协同有显著正向影响。 相似文献

In this paper we analyse if specific R&D cooperation partners are related to an increase in the probability of innovation failures in terms discontinuing innovation projects. We distinguish between seven different R&D cooperation partner types, and we discriminate between product innovation failures and process innovation failures. Using German Community Innovation Survey data we find that, firstly, each type of R&D cooperation partner has a different effect on innovation failures. Secondly, we show that product innovation failures and process innovation failures are not affected in equal measure by the same type of R&D cooperation partner. Our results suggest that while R&D cooperation with public research institutes is significantly and negatively related to the probability to cancel a process innovation project, the coefficient is positive but insignificant for product innovation failures. Firms conducting partnerships with suppliers, however, run the risk of both product and process innovation failures. In turn, cooperation with competitors is positively correlated only to process innovation failures. 相似文献
