Future costs and revenues in capital investment opportunities can seldom be predicted with certainty. As a result, there is usually some doubt as to the outcome of an investment. The chance that an investment may not prove profitable represents the investor's risk. This paper considers the problems which uncertainty and risk present in the evaluation of capital investments. Several traditional methods of dealing with uncertainty and risk are considered and shown to be deficient. A relatively new evaluation technique, which utilizes probability theory and computer simulation, is then described and its advantages highlighted. It is suggested that this technique will prove valuable in the evaluation of future marine capital investments. 相似文献

In this research the impact of two types of end anchors on the linearity of the category rating scale is studied. Two functional
measurement experiments were carried out, each requiring a different kind of judgement, i.e., job satisfaction ratings and
attractiveness ratings. One group of participants rated the stimuli using a category rating scale with fixed anchors, while
another group was presented with a self-anchoring category rating scale. The results indicate that researchers can be confident
in the ability of both category rating scales to provide linear data. This implies that the different end anchors do not impact
on the linearity of the category rating scale. 相似文献

Daily diaries are a widely used measurement tool in studies on the use of social time. However, while their high level of
accuracy is supported by a lot of research, scholars often voice doubts regarding the validity of the estimates obtained if
the characteristic rhythm of the events in question is not completed within a 24-h period. This study attempts to explain
why, although these statistics are not wrong, they need to be understood correctly before proceeding with research based on
them. To overcome the problem we will propose a solution for new surveys where use of diaries of this type is scheduled. Although
this solution is not without limitations, they are much less restrictive than those imposed by traditional daily diaries. 相似文献

The paper investigates cross-country differences in wage mobility in Europe using the European Community Household Panel.
We examine the impact of specific wage-setting institutions, such as the collective bargaining and the trade union density,
the employment protection regulation and the welfare state regime on wage mobility. We apply a log-linear approach that is
very much similar to a restricted multinomial logit model and much more flexible than the standard probit approach that is
typically applied in the research on wage mobility. It is shown that the macro-economic context and the aforementioned specific
institutions explain a substantial part of the cross-country variation that is larger than the part that regime type explains.
The findings also confirm the existence of an inverse U-shape pattern of wage mobility, showing a great deal of low-wage and
high-wage persistence in all countries. 相似文献

In this paper a fuzzy quality function deployment to identify service management requirements for customer quality needs is
developed. First, customer quality needs with importance degree have been investigated followed by development of service
management requirements for satisfying the observed customer quality needs. Furthermore, construct a fuzzy relation matrix
to link service management requirements and customer quality needs based on cross-functional expertise. The aggregated fuzzy
assessments of various service management requirements are ranked to determine their importance priority. Finally, an empirical
study for identifying the service management requirements for customer quality is used to demonstrate the proposed approach. 相似文献

Our study investigated the follower perceptions of leader–member exchange (FPLMX) as a mediator between leader political skill (LPS) and follower morale and tested these relationships using data obtained from casino dealers in Korea. Social astuteness, interpersonal influence, networking ability, and apparent sincerity are the indicators of LPS, while follower morale is composed of job satisfaction and affective organizational commitment. The results from structural equation modeling suggest that the research model we have proposed is viable. Broadly speaking, FPLMX is a partial mediator between LPS and follower morale. 相似文献

We study the economic and non-economic sources of stock return comovements of the emerging Indian equity market and the developed equity markets of the US, UK, Germany, France, Canada and Japan. Our findings show that the probability of extreme comovements in the economic contraction regime is relatively higher than in the economic expansion regime. We show that international interest rates, inflation uncertainty and dividend yields are the main drivers of the asymmetric return comovements. Findings reported in the paper imply that the impact of interest rates and inflation on return comovements could be used for anticipating financial contagion and/or spillover effects. This is particularly critical since during extreme market conditions, the tail return comovements can potentially reveal critical information for active portfolio management. 相似文献
