This paper reports on a study to compare self-reports during an interview with staff who attended a University health centre in Turkey, with the records of visits to the same health centre over the previous 12 months. Design of the study reflects the effects of importance of the event, duration since the event, frequency of the occurrence of the event, measurement scale of the event, and bounded and unbounded recalling. In order to assess the extent of recall error, responses to retrospective questions on health centre visits are compared with administrative records. Statistical models are proposed for short and long term human memory recall error effects on responses. 相似文献

In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend
hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential
for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment.
To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity
and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same
time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63) 相似文献

This article presents the results of an establishment level investigation carried out late in 1986 and early in 1987 of the extent of flexible manpower resourcing in the Aberdeen local labour market. It is necessary to place these results in the context of the general background of an increasing interest in flexible manning and of certain theoretical developments in labour and industrial economics. The results suggest that whilst a variety of means are used to attain flexibility in manning, few establishments can be regarded as truly ‘flexible firms’ and manpower strategies tend to be largely reactive and ad hoc. 相似文献

Polyhedral combinatorics is a subarea of combinatorial optimization of increasing practical importance. It deals with the application of the theory of linear systems and linear algebra to combinatorial problems. The paper is not intended as a survey on polyhedral combinatorics but it reviews some of the main concepts and proof techniques. 相似文献

Banks were substantially deregulated during the 1980s. This altered the cost-minimizing mix between deposit interest payments and operating expenses (capital and labor for branch convenience and free deposit services). Measured bank output was relatively unaffected by these changes. The proportion of deposits receiving higher interest rates increased more rapidly than factor quantities were reduced, so unit deposit costs rose. Consumers benefited, but the measured net effects for banks were negative, averaging –0.8% to –1.4% a year in net technical change from 1977 to 1988. These influences were measured three different ways and for both equilibrium and disequilibrium factor input specifications. All three approaches—a standard time trend, a time-specific index, and shifts in cross-sectional cost functions—gave consistent results. The results were robust whether measured at the banking firm or branch office level or on the cost frontier. 相似文献

The HIV/AIDS epidemic has focused increased attention on catastrophic illnesses in the workplace, and because of the stigmas associated with HIV/AIDS, it raises three primary concerns for organizations: (1) organizational avoidance of legal sanctions and litigation; (2) the maintenance of organizational legitimacy; and (3) organizational protection of employee rights. Although many organizations adopt legalistic responses to cope with these concerns, the analysis presented in this article suggests that while legalistic approaches function well to protect organizational interests in terms of both legal liability and legitimacy, the are only partially able to protect employee rights. Drawing upon the limited literature on HIV/AIDS in the workplace, this article presents an agenda for future research on organizational responses to HIV/AIDS. 相似文献

Abstract In this paper we propose distribution-free treatments versus control tests for the one- and two-way classifications. The null distribution properties are shown to be equivalent to those of well-known statistics for which critical values have been extensively tabled. Asymptotic relative efficiencies with respect to corresponding normal theory competitors are derived and optimal designs for the allocation of experimental units to the treatments and control are obtained. 相似文献

Summary We consider the problem of making inferences about the parameters of a time series model when there is the possibility of a discrete variance change at an unknown time point. For this we obtain the posterior distributions of the parameters and of the variance ratio. 相似文献

Summary In this paper it is investigated whether robust estimation procedures for the parameters of a regression model are also applicable when the observations are generated by the errors-in-variables model. Specifically, attention is paid to bounded-influence estimators, i.e. estimators that are constructed in such a way that the influence of a single observation on the outcome of the estimator is bounded. Both the classical errors-in-variables model and models with contaminated observational errors are considered.The authors are indebted to a referee for his valuable comments on an earlier version of this paper. 相似文献

A bstract . Developing countries have called for the establishment of a new International Economic Order. New perceptions of development are examined as they relate to haste needs and the transfer of technology within such a framework. The approach seeks to reduce and eventually to eliminate dependence on developed country enterprises, thus allowing developing countries to control their natural resources. It seeks to accelerate self-reliance and to introduce some measure of global management of resources. Technology transferred must be appropriate technology, adapted to local conditions and aimed at meeting specific local needs. 相似文献
