The labor force of the future.

In the decades ahead, the US labor force will reflect changes in the industrial structure, with declines in some manufacturing industries and expansion in service industries. The services sector is so diverse that the jobs within it cannot be categorized as either high wage or low wage. The service-producing sector employs 85% of professional specialty workers in the US. In general, information on compensation trends indicates that greater increases in compensation have occurred for workers in service-producing as opposed to goods-producing industries. The increase in service sector jobs has created opportunities for women to enter the labor force and, at present, 5 out of 6 women work in this sector compared to fewer than 2 out of 3 men. Productivity growth rates in the service-producing industries vary substantially and are strongly affected by the business cycle. Central to employment opportunities in the years ahead will be the effect of new technology. To date, the aggregate effect of new technology has been increased employment and higher living standards. Although retraining programs should be in place, the scenario of a huge technology-created labor surplus seems unlikely. In fact, a more likely problem is a shortage of labor resulting from earlier labor force withdrawal and demographic aging of the population. Those in the 25-54-year age group will represent a larger share of the labor force in the years ahead. In addition, blacks are expected to account for 20% of the labor force growth in the next decade. Finally, given increasing labor force participation rates among mothers, employers may have to provide more flexible work schedules, assistance with day care, and more attractive benefits packages.     

Shared meal preparation in residential kitchens: implications for kitchen planning

A comparison was made of the use of residential kitchen work centres by one worker and by two workers during a dinner meal preparation in which a microwave oven was utilized. When the meal was prepared by two workers they divided the work load by menu item and utilized separate work stations; typically, only one worker prepared the menu items requiring actual cooking. However, whether the meal preparation was individual or shared, the sink and preparation centres were the most frequently used.     

Identifying the gaps in ethical perceptions between managers and salespersons: A multidimensional approach

This research examines, in a general manner, the degree and character of perceptual congruity between salespeople and managers on ethical issues. Salespeople and managers from a diversity of organizations were presented with three scenarios having varying degrees of ethical content and were asked to evaluate the action of the individual in each scenario. Findings indicate that, in every instance, the participating managers tended (1) to be more critical of the action displayed in the scenarios, (2) to view the action as violating a sense of contract or promise, and (3) to view the action as less culturally acceptable than did the salespeople.Tony L.

The road to a market economy

The ongoing conversion of the economies of former socialist countries into market economies has so far suffered from the lack of a theory of system transformation (policy) which indicates the means of achieving the desired objectives and makes it possible to evaluate the transformation policies of individual countries. The following article outlines the essential aspects of such a theory.     

用于高频的新颖开关电容积分器

本文研究了用于开关电容(SC)滤波器的离散积分器,所推荐的积分器是由无耗离散积分器(LDI)和双线性离散积分器的最佳线性结合而成,因此,称之为组合离散积分器(CDI)。由于这个积分器使正常转折频率增加一倍,并使高频离散积分器误差减少到最低限度,所以它对高频应用是理想的。文中给出了组合离散积分器的几种SC实现,并且还给出了以组合离散积分器为基础,模拟一般一阶和二阶的模拟滤波器单元的SC电路。     

Creating a Testable, Estimable Model to Inform Our Response to the Test-Score Gap Crisis

The test-score gap between black and white students should be seen as a crisis. We propose a testable model based on readily available data that will allow us to estimate the impact and interrelationships of a multitude of factors that may be partially responsible for the problem. The estimation of this model will require the joint efforts of experts in many areas of education as well as of experts in multilevel structural equation modeling.     

Répercussions de la Pension Protection Act de 2006 sur la valeur boursière

Les auteurs étudient les répercussions de la Pension Protection Act de 2006 (PPA 2006) sur la valeur boursière des actions. La PPA 2006 contient deux dispositions principales : 1) les entreprises doivent assurer la capitalisation intégrale de leur régime de retraite en sept ans (alors qu’une période de trente ans leur était auparavant accordée pour capitaliser 90 pour cent de leur passif au titre du régime) et 2) elles peuvent se prévaloir d’une déduction fiscale à l’égard des cotisations à concurrence de 150 pour cent du passif au titre du régime (alors que le plafond de la déduction était antérieurement de 100 pour cent). Une fois contrôlés l’incidence de la norme SFAS 158, les possibilités de croissance, le coût du financement externe et les autres informations publiées au cours de la période d’échantillonnage, les auteurs examinent les rendements anormaux des entreprises ayant un régime de retraite, à proximité des dates marquantes du processus législatif ayant menéà l’adoption de la PPA 2006. Premièrement, ils observent un rendement anormal moyen négatif de – 4,20 pour la période au cours de laquelle la PPA 2006 a fait l’objet d’un premier vote au Congrès. La capitalisation boursière de l’entreprise moyenne (médiane) de l’échantillon a enregistré un déclin de 310 millions de dollars (60 millions de dollars). Deuxièmement, les auteurs constatent que les répercussions sur la valeur boursière sont plus négatives dans le cas des entreprises présentant des passifs non capitalisés plus importants au titre du régime et devant faire face à des dépenses en immobilisations plus substantielles, alors que les entreprises dont les taux d’imposition marginaux sont plus élevés enregistrent des répercussions positives. Troisièmement, les auteurs ne relèvent aucun élément permettant d’affirmer que les répercussions sur la valeur boursière varient selon les différentes catégories de risque définies par la PPA 2006. Enfin, ils recensent un nombre appréciable de cas de blocage du régime au cours de la période soumise à l’étude. Les résultats sont plus marqués encore lorsque ces entreprises sont retirées de l’échantillon.
