汉语成语中数字模糊性的理解及其行文翻译   总被引:3,自引:0,他引:3  
汉语成语中的数字所表达的数量概念具有模糊性.在数词构成的汉语成语的行文翻译时,既要考虑结构的形式,更要注重数字所蕴含的模糊表意功能,处理好形与意之间的关系.  相似文献

We propose the notions of mixed and behavioral Ellsberg strategies for extensive form games and prove that these strategies are outcome-equivalent if and only if mixed Ellsberg strategies satisfy a certain rectangularity condition. In addition, we show that not only the profile of Ellsberg strategies must be appropriately chosen but also the extensive form must satisfy further restrictions beyond those implied by perfect recall in order to ensure that each player will respect his ex ante strategy choice with the evolution of play.  相似文献

This study examines how and why entrepreneurial passion for founding changes over time. In particular, we propose that in the founding phase of a venture's lifecycle entrepreneurs’ founding identity centrality will remain stable over time. We also propose, however, that in our sample and time period studied, entrepreneurs’ intense positive feelings for founding will decrease over time. On the basis of theories of positive illusion, self‐regulation and role theory, we further hypothesize that venture idea change, change in role ambiguity and entrepreneurs’ feedback‐seeking behaviour are factors that help explain the rate of change in entrepreneurs’ intense positive feelings for founding. Using a three‐wave longitudinal research design, we find that among a sample of 112 entrepreneurs’ identity centrality does not change over time, whereas intense positive feelings for founding decrease over time. Moreover, the more entrepreneurs change their venture ideas, the weaker their decrease in intense positive feelings. Further, we show that entrepreneurs who frequently seek feedback suffer less from reduced positive feelings in response to higher increases in role ambiguity as compared to entrepreneurs who seek less feedback.  相似文献

This paper investigates whether familiarity induced by ambiguity aversion can help explaining the local bias phenomenon among individual investors. Using geographic closeness as a proxy for investor familiarity, we find that investors pull out of (unfamiliar) remote stocks and pour into (familiar) local stocks during times of increased market uncertainty. Moreover, the magnitude of this ‘flight to familiarity’ increases in the spread of an investor's ambiguity (about expected returns) between local and remote stocks. Our results prove robust to a number of alternative explanations of local bias. Specifically, we rule out a ‘home-field advantage’, where investors are able to translate information advantages about nearby companies into excess returns on their local stockholdings. We conclude that individual investors’ local bias is induced by ambiguity aversion in the portfolio selection process rather than a trading strategy based on superior information about local companies.  相似文献

We study the impact of ambiguity on the pricing and timing of the option to invest. There is a funding gap to undertake the investment, which is covered by entering into an equity-for-guarantee swap. Our model predicts that the more ambiguity-averse the agents, the less the option value, the later the investment and the higher the guarantee cost and the leverage. If the entrepreneur is more ambiguity-averse than the insurer, the investment threshold slightly rises as the perceived ambiguity increases, and on the contrary, if the entrepreneur is less ambiguity-averse than the insurer, the investment threshold increases sharply as the perceived ambiguity rises.  相似文献

Standard finance theory suggests that managers invest in projects that, in expectation, produce returns that justify the use of capital. An underlying assumption is that managers have the information necessary to understand the distributional properties of the pay‐offs underlying the decision. This paper examines firm investment behavior when managers are likely to find it more challenging to develop expectations of pay‐offs, namely during periods of increased macroeconomic ambiguity. In particular, we examine how macroeconomic ambiguity – proxied by the variance premium (Drechsler, 2010 ) and the dispersion in forecasts of corporate profits from the Survey of Professional Forecasters (Anderson et al., 2009 ) – impacts managerial capital investment and cash holdings. Consistent with ambiguity theory, we find that macroeconomic ambiguity is negatively associated with capital investment and positively associated with cash holdings. These results are robust to alternative explanations related to risk, investor sentiment and economic conditions. Moreover, consistent with recent theoretical real options literature, we find that ambiguity reduces the value of investment opportunities, while risk increases the value of such opportunities. Overall, these findings provide initial empirical evidence on the economic distinction between ambiguity and risk with respect to managerial investment and cash holdings.  相似文献

Under what conditions does a collective strategy exist among organizational members? Where should a scholar look for one? To offer one way to start solving these puzzles I propose a view of organizational strategy as a language game that governs the use of strategy labels at the level of the organization. Organizational strategy exhibits a division of linguistic labour, where responsibility for key concepts is assigned to particular individuals or organizational functions. Such linguistic experts oversee the proper use and maintenance of strategy language. The language‐based view helps to understand linkages between institutional, network, organizational, and micro level views on strategy. It also problematizes widely held intuitions regarding the relationship between strategy and organizational outcomes.  相似文献

This work investigates the equilibrium investment and reinsurance strategies for a general insurance company under smooth ambiguity. The general insurance company holds shares of an insurance company and a reinsurance company. The claims of the insurer follow a compound Poisson process. The insurer can divide part of the insurance risk to the reinsurer. Besides, the insurer and reinsurer both participate in the financial market and invest in cash and stock. However, the general insurance company is ambiguous about the insurance and financial risks and is an ambiguity-averse manager (AAM). The uncertainties over the insurance and financial risks are described by second-order distributions. The AAM aims to maximize the average performance of the weighted sum surplus process of the insurer and reinsurer under the mean–variance criterion and smooth ambiguity. We present the extended Hamilton–Jacobi–Bellman (HJB) system for the optimization problem combining the mean–variance criterion and smooth ambiguity. In the case that the second-order distributions are Gaussian, we obtain the closed-forms of the equilibrium reinsurance and investment strategies. At the end of this work, sensitivity analyses are presented to show the economic behaviors of the AAM.  相似文献
