Occupational status attainments of university graduates: individual attributes and labour market effects compared

Ce document analyse le processus de realisation d'un statut professionnel pour cinq cohortes de diplômés d'université, hommes et femmes, durant la période s'étendant de 1960 à 1976. Après avoir reçu leurs diplômés, les hommes, comparés à leurs homologues féminins, sont parvenus, en general, à un statut professionnel plus élevé, réparti sur une échelle plus large. Les conséquences des differences socio-économiques sur la réalisation d'un statut professionnel se sont avèrées minimes ou insignifiantes pour les deux sexes. Les effets des différences de l'enseignement reçu sur le statut professionnel sont plus grands. Les rendements pour l'étudiant avec une moyenne académique élevée sont les mêmes pour les hommes que pour les femmes. Les hommes qui ont poursuivi de hautes études supérieures ont éprouvé un meilleur rendement de méme que les femmes qui se sont spécialisées en sciences. La condition du marché du travail au moment ou ces étudiants ont obtenu leurs diplômes s'est avérée le facteur le plus déterminant dans la réalisation d'un statut professionnel. L'on maintient que la recherche sur la réalisation d'un statut professionnel a largement négligé les facteurs structurels tels que les conséquences du marché du travail, et sa concentration sur le prestige professionnel a entretenu le déguisement des differences entre les sexes dans la réalisation d'un statut professionnel. This paper analyzes the occupational status attainment process for five cohorts of male and female university graduates spanning the time period 1960 to 1976. When compared to their female counterparts, males on the whole achieve higher occupational status after graduation and experience a wider distribution of status. The effect of socioeconomic variables on occupational attainment are found to be either small or insignificant for both sexes. The effects of educational variables on occupational attainment are greater. The returns to a high undergraduate academic average are similar for males and females; males experience a higher return to graduate study while females experience a larger return to majoring in science. The state of the labour market at time of graduation is found to have the largest effect on occupational status attainment. It is argued that occupational status attainment research has largely neglected such structural factors as labour market effects, and its focus on occupational prestige has tended to mask sex differences in occupational status attainment.     

Marital relationships as a cause of death: an analysis of occupational mortality and the hidden consequences of marriage--some U.K. data.

The relationship between a married woman's life expectancy and the occupation of her husband is explored using official data for the United Kingdom for 1959-1963 and 1970-1972. The author notes that not only are there large and specific effects of employees' occupations on life expectancy and mortality rates, but that these mortality differentials also affect the spouses of those in high-risk occupations. It is suggested that such occupational risks are transmitted via the domestic psychological environment to the married women concerned, and thus the males' job risks affect the life expectancy of both partners.     

IMPOSED HEALTH INSURANCE IN MONOPOLISTIC MARKETS: A THEORETICAL ANALYSIS

The impact of public health insurance on price and output of medical care is analyzed within the context of monopolistic markets for health services. An important result, which is not obtained in competitive markets, is that indemnity benefits cause smaller price increases than service benefits, both directly and indirectly through the effect of benefit structure on the production of information. Various types of price regulation are considered, including limitation to "usual, customary, and prevailing" levels, a frequently used technique. With a simple dynamic model this type of regulation is shown to cause chronic price inflation.     

Conservative linear programming with mixed multiple objectives

In an ordinary linear program a single objective vector is constructed and one attempts to choose a decision vector to optimize this objective. Often multiple criteria exist or exact estimates for the components of a single objective vector are not entirely clear. For these cases a conservative decision-maker may want to choose an alternative that maximizes the objective value under the worst foreseeable circumstances. Herein we develop a unified framework for applying the maximin criterion to problems with various degrees of uncertainty attached to the objective vector. Three cases are solved via linear programming: (1) Complete Information, (2) Partial Information, and (3) Total Ignorance. It is shown that the functional value of the maximin solution decreases in a convex manner with increasing uncertainty. In addition certain relationships between maximin and efficient solutions are provided. Finally, an extension to integer constrained decision variables is presented.     

天线罩覆盖的波束近轴场

本文根据复射线法对通过介质天线罩的高斯波束场进行近轴近似分析。实空间的轴向复射线追综大大简化了计算过程,而复相位差、反射-传输系数和曲面扩散系数的进一步校正则提供了相当精确的结果。所得数字结果表明,在波束的近轴区域内为获得同样的计算精度,近轴近似法所需要的计算机时间远小于复射线追综法的时间。     

Venture management—success or failure?

The considerable amount of published literature on venture management is reviewed in an attempt to see how successful this technique is in promoting new products. It was found that earlier articles were optimistic but later articles were more realistic with several describing failed projects.

An attempt is made to relate this with the published literature on the failure of traditional Research and Development but little published evidence is available. The role of New Towns in innovation is briefly mentioned. Finally the reasons for failure are identified and guidelines are established as a means of making venture groups more successful.
