Abstract: The application of RPD decision analysis to R & D tactics is discussed and the role of the technique as an aid to self-consistent decision making is enaphasized. RPD decision analysis is used to define limits to its own cost effectiveness.
Two example problems are analysed in detail. Simple priority ratings are defined for two special cases: the sequence of independent tests all of which must succeed, and the sequence of independent problem solving attempts, any of which may succeed. The compromise between project duration and project cost is analysed in terms of time dependence of the value of success.
The discrimination study is defined as an investigation which aims to provide information for an improved assessment of project success probability.
It is shown that such a study is never worth more than one quarter of the total expected benefits of the project.  相似文献

We identify three types of information from bank examinations—auditing information from verifying the honesty and accuracy of the bank's books, regulatory discipline information about the treatment of the bank by regulators, and private information about bank condition. We estimate these information effects by comparing the cumulative abnormal market returns associated with examinations in which the CAMEL rating remained unchanged, improved, and worsened. All three information effects are found to be greater for banks entering the examination process with unsatisfactory ratings from prior examinations. The only consistently strong effect found is that examination downgrades appear to reveal unfavorable private information about bank condition. The evidence also suggests that the information may reach the market in part through loan quality data released in quarterly financial statements.  相似文献

Everyone is talking about accountability but it is a hard concept to pin down. The Audit Commission commends some of the Governments’ reforms, but believes that ultimately it will be people who will determine whether a better system of accountability emerges.  相似文献

Abstract

Parents play a critical role in promoting fruit and vegetable consumption, for eating patterns established early in life tend to persist into adulthood. Despite this, the factors that facilitate or inhibit parents’ capacity to socialise fruit and vegetable consumption into their children’s daily diets remain poorly defined. Thirty-eight semi-structured interviews with residents, allied healthcare professionals, community leaders, community programme leaders and a local government leader living or working in two low socioeconomic suburbs were consequently conducted to ascertain factors exogenous and endogenous to the family unit that shaped parental food socialisation practices. Budgetary and time constraints emerged as exogenous factors that constrained fruit and vegetable socialisation. Constraining effects were also found for a range of endogenous factors, including commensal experiences, children’s food fussiness and the feeding styles employed by parents. As such, while many caregivers may wish to socialise fruit and vegetable consumption into their children’s daily diets, their capacity to do so is often inhibited by factors beyond their volitional control. Failure to take heed of these factors could therefore result in the development of social marketing campaigns that are ineffective at best or give rise to unintentionally harmful outcomes at worst.  相似文献

The Effects of Bilateral Tax Treaties on U.S. FDI Activity   总被引:1,自引:0,他引:1  
The effects of bilateral tax treaties on FDI activity have been unexplored, despite significant ongoing activities by countries to negotiate and ratify these treaties. This paper estimates the impact of bilateral tax treaties using both U.S. inbound and outbound FDI over the period 1980–1999. Robust to a wide variety of alternative specifications, we find little evidence that bilateral tax treaties increase FDI activity, contrary to OECD-stated goals for such treaties.  相似文献

Using a unique primary dataset for the UK, we estimate the effect of individual teachers on student outcomes, and the variability in teacher quality. This links 7,305 pupils to the individual teachers who taught them, in each of their compulsory subjects in the high‐stakes exams at age 16. We use point‐in‐time fixed effects and prior attainment to control for pupil heterogeneity. We find considerable variability in teacher effectiveness, a little higher than the estimates found in the few US studies. We also corroborate recent findings that observed teachers’ characteristics explain very little of the differences in estimated teacher effectiveness.  相似文献

We review three alternative approaches to modelling survey non‐contact and refusal: multinomial, sequential, and sample selection (bivariate probit) models. We then propose a multilevel extension of the sample selection model to allow for both interviewer effects and dependency between non‐contact and refusal rates at the household and interviewer level. All methods are applied and compared in an analysis of household non‐response in the United Kingdom, using a data set with unusually rich information on both respondents and non‐respondents from six major surveys. After controlling for household characteristics, there is little evidence of residual correlation between the unobserved characteristics affecting non‐contact and refusal propensities at either the household or the interviewer level. We also find that the estimated coefficients of the multinomial and sequential models are surprisingly similar, which further investigation via a simulation study suggests is due to non‐contact and refusal having largely different predictors.  相似文献

This article examines the enactment of new public management (NPM) in public service professional organizations, the nature of professional/managerial subjectivities promoted within the NPM discourse, and the implications for male and female professionals/managers. The article has two aims. First, taking a gender ing organization perspective, it explores the gendered meanings of NPM and the promotion of new professional/managerial subjectivities. Second, focusing on gender in organizations, the article then considers the implications of the enactment of NPM for male and female professionals/managers. The article illustrates the complex, manifold and fluid nature of both the meanings ascribed to NPM and individual responses. It is argued that a gender lens offers a more nuanced and sophisticated understanding of NPM enactment and the implications of this for public service professionals/managers are considered.  相似文献
