To address agility in public administration, we have developed a knowledge acquisition infrastructure for legal knowledge, based on an implementation‐oriented conceptualization of the legal system. Our objective is to reframe legal knowledge as a knowledge source in a design‐oriented task ontology, building on insights from the CommonKADS methodology for intelligent system design. The main result is to make case law and legal expert knowledge of critical incidents in organizations, two diagnostic knowledge sources underutilized in modern management and engineering, more accessible as a resource for design of agile organizational structures and intelligent systems.

Abstract The objective of this paper is to investigate dynamic properties of age trajectories of physiological indices and their effects on mortality risk and longevity using longitudinal data on more than 5,000 individuals collected in biennial examinations of the Framingham Heart Study (FHS) original cohort during about 50 subsequent years of follow-up. We first performed empirical analyses of the FHS longitudinal data. We evaluated average age trajectories of indices describing physiological states for different groups of individuals and established their connections with mortality risk. These indices include body mass index, diastolic blood pressure, pulse pressure, pulse rate, level of blood glucose, hematocrit, and serum cholesterol. To be able to investigate dynamic mechanisms responsible for changes in the aging human organisms using available longitudinal data, we further developed a stochastic process model of human mortality and aging, by including in it the notions of “physiological norms,” “allostatic adaptation and allostatic load,” “stress resistance,” and other characteristics associated with the internal process of aging and the effects of external disturbances. In this model, the persistent deviation of physiological indices from their normal values contributes to an increase in morbidity and mortality risks. We used the stochastic process model in the statistical analyses of longitudinal FHS data. We found that different indices have different average age patterns and different dynamic properties. We also found that age trajectories of long-lived individuals differ from those of the shorter-lived members of the FHS original cohort for both sexes. Using methods of statistical modeling, we evaluated “normal” age trajectories of physiological indices and the dynamic effects of allostatic adaptation. The model allows for evaluating average patterns of aging-related decline in stress resistance. This effect is captured by the narrowing of the U-shaped mortality risk (considered a function of physiological state) with age. We showed that individual indices and their rates of change with age, as well as other measures of individual variability, manifested during the life course are important contributors to mortality risks. The advantages and limitations of the approach are discussed. 相似文献

The analysis of diffusion processes in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A new model for a stock market index process is proposed in which the index is decomposed into an average growth process and an ergodic diffusion. The ergodic diffusion part of the model is not directly observable. A methodology is developed for estimating and testing the coefficient functions of this unobserved diffusion process. The estimation is based on the observations of the index process and uses semiparametric and non-parametric techniques. The testing is performed via the wild bootstrap resampling technique. The method is illustrated on S&P 500 index data. 相似文献

In this paper, we study how risk-shifting incentives and the design of debt covenants are affected by the pattern of temporal resolution of uncertainty (TRU) in the underlying technology of the firm. We show that the extent of risk-shifting as well as the yield demanded on corporate debt are larger the later the resolution of uncertainty (thus providing one explanation for the empirical evidence of Reisz and Perlich (2006)). We allow for contracting based on verifiable information disclosed by the manager. In this context, we characterize optimal covenants restricting investment. The effects of these covenants on the firm's investment policy and corporate bond yields under different disclosure policies and patterns of TRU are studied. Empirical implications are derived and discussed. 相似文献

Research on senior executive reward has typically explored the connection between pay, performance and the alignment of interests of executives and shareholders. This article examines the relationship between reward and motivation, drawing on the psychological, behavioural economics and decision‐making literatures. Based on an empirical study of FTSE 350 senior executives, the research examines whether long‐term incentive plans are an effective and efficient way of motivating executives, taking into account risk, time discounting, uncertainty and fairness. The article concludes that the way executives frame choices, perceive value, assess probability, evaluate temporal effects and respond to uncertainty means that long‐term incentive plans (LTIPs) are generally not efficient and are often not effective in meeting their objectives. It proposes that, in its current form, agency theory does not provide a sound basis for modelling senior executive reward, and suggests five areas for development. 相似文献

The notion of empowerment has been used in the management discourse since at least the 1980s. As a normative model for the distribution of decision-making mandate and administrative and operative responsibilities, empowerment serves as a new shopfloor model or ideology for decentralized organizations of the new workplace. The practice of empowerment is, however, not very often empirically researched, causing a confusion about what empowerment implies in terms of shopfloor activities. This paper presents an extensive organization development programme at a Swedish telecommunication company. Rather than being an easily implemented model, empowerment appears as a complex, heterogeneous process in which the empowering of employees is embedded in local practices and workplace cultures. 相似文献

We study how the sequence of financing of R&D varies according to the ease with which property rights over knowledge can be defined. There are two financiers: a venture capitalist (VC) and a corporation. The knowledge acquired in costly research becomes embodied in the researcher's human capital, and she may hold up the financier and walk away with the project to develop it elsewhere. The main results are: (1) When property rights are strong, research is always funded by the VC, development is performed efficiently, and breakaways from the VC to the corporation are observed in equilibrium. (2) When property rights are weak, projects may be financed by the VC or the corporation, or may remain unfunded. (3) When property rights are weak, no breakaways occur in equilibrium; local spillovers and strong product market competition increase the likelihood that research projects will get funding. (4) The equilibrium sequence of R&D finance need not be first-best efficient. (5) In equilibrium, and controlling for the strength of property rights, VCs finance projects that are more profitable on average. 相似文献

Policy debates suggest a future role for geologic carbon sequestration. As geologic sequestration (GS) evolves from enhanced oil recovery operations to an emissions‐mitigation option, regulations must evolve to manage the risks of carbon dioxide (CO2) migration. We develop an engineering‐economic model to understand the key deployment pathways in this transition. Major results reveal that dedicated CO2 storage in aquifers is associated with the greatest net revenues under only a limited number of scenarios. This finding suggests that regulators should anticipate GS operations in reservoirs that were not initially intended as GS operations and, therefore, may have higher leakage rates.

The open innovation approach has been one of the most discussed topics in innovation management literature in the 2000s. Over the past few years, academic publications on open innovation have increased substantially. This paper attempts to summarize and review the state-of-the-art of empirical open innovation research and develop new opportunities for open innovation research in the future. In order to make the papers more comparable, a clear focus on large-scale quantitative-oriented studies was set. From a total of 282 documents, 30 studies were analyzed in detail along four key dimensions: Firstly, different methods of measuring open innovation adoption are compared. Then, the level of open innovation adoption is analyzed on a general basis. Thirdly, the level of adoption is compared at the level of the open innovation mode (inbound and outbound). Finally, the study results regarding the variables that influence open innovation adoption are compared and conclusions for future research directions are drawn. 相似文献
