Transistor bonding pad configuration for uniform injection and low inductance

Modification of process for fabricating transistors, which comprises a metallization-pattern design for emitter and base areas together with a double bonding configuration for each emitter and base-bonding lead, improves uniformity of carrier injection in transistors and of reducing lead inductances at base-emitter terminals

High-temperature durability considerations for HSCT combustor

The novel combustor designs for the High Speed Civil Transport will require high temperature materials with long term environmental stability. Higher liner temperatures than in conventional combustors and the need for reduced weight necessitates the use of advanced ceramic matrix composites. The combustor environment is defined at the current state of design, the major degradation routes are discussed for each candidate ceramic material, and where possible, the maximum use temperatures are defined for these candidate ceramics

Congressional Testimony on the Effectiveness oof the Employment Service in Aiding UI Claimants

This testimony describes the results of a study of the Employment Service (ES) conducted by Dr. Jacobson and Prof. Arnold Katz of the University of Pittsburgh using data on over 100,000 individuals who registered with the Pennsylvania ES between 1978 and 1987, and an even larger sample of non-registrants. One major finding is that much of the decline in the ES's performance over the past thirty years can be explained by changes in: funding, characteristics of registrants, and characteristics of job vacancies. Thus, we concluded that criticism of the ES often ignores changes in crucial factors outside of the ES's control that reduced its effectiveness. A second major finding is that most criticism of the ES is based on the inappropriate assumption that the primary goal of the ES should be to maximize placements. The proper measure of ES benefits is how well it reduces joblessness, increases earnings, and reduces UI and welfare payments. We found that the ES reduced the average duration of unemployment of long-term UI claimants by nine weeks. This was for UI claimants who were unemployed for at least 30 weeks. But the ES reduced joblessness of claimants unemployed for 12 weeks by less than two weeks. This is evidence that the ES is most effective in aiding claimants who had substantial trouble finding work on their own. But we suspect that the jobs found with the help of the ES do not compare favorably with jobs held prior to becoming unemployed. Thus, we believe the ES primarily acts as a backstop preventing large earnings losses. Finally, although savings in UI benefits and increases in earnings created by the ES may be modest, the cost of ES service is so low, $75 on average, that modest benefits would more than offset those costs. We believe our results, coupled with similar findings from related studies, is sufficiently strong to warrant increasing the funding of the ES. That measure is favored because it would be at least budget neutral. In contrast, other measures to assist the long-term unemployed, such as providing extended UI benefits or training, would not come close to being budget neutral. In addition,$1 spent on job search assistance is likely to be more effective in helping claimants than $1 spent on training.unemployment, insurance, employment, service, displaced, dislocated, Jacobson

Core-periphery analysis: a tale of two nations

Bias, unreliability and omission have been documented in traditional sources of trade data; the lack of service data in trade statistics is the most frequently cited shortcoming. Current trade liberalization is likely to exacerbate these deficiencies. This paper develops and applies a location quotient based methodology for analysing core-periphery dualism, thus obviating the use of trade data. Our application to the European Union shows agglomeration in core areas of high technology, large scale manufacturing, and producer service industries. Peripheral countries are shown to specialize in agriculture, extractives, low technology manufacturing, and standardized production. Detailed examination of two peripheral economies, Ireland and Denmark, finds that each departs from the mean of peripheral nations. A comparison of proxied trade data to actual trade data indicates that the location quotient method is a statistically viable means of proxying trade patterns

What do peer support workers do? A job description.

BackgroundThe extant literature suggests that poorly defined job roles make it difficult for peer support workers to be successful, and hinder their integration into multi-disciplinary workplace teams. This article uses data gathered as part of a participatory evaluation of a peer support program at a psychiatric tertiary care facility to specify the work that peers do.MethodsData were gathered through interviews, focus groups, and activity logs and were analyzed using a modified grounded theory approach.ResultsPeers engage in direct work with clients and in indirect work that supports their work with clients. The main types of direct work are advocacy, connecting to resources, experiential sharing, building community, relationship building, group facilitation, skill building/mentoring/goal setting, and socialization/self-esteem building. The main types of indirect work are group planning and development, administration, team communication, supervision/training, receiving support, education/awareness building, and information gathering and verification. In addition, peers also do work aimed at building relationships with staff and work aimed at legitimizing the peer role. Experience, approach, presence, role modeling, collaboration, challenge, and compromise can be seen as the tangible enactments of peers' philosophy of work.ConclusionsCandidates for positions as peer support workers require more than experience with mental health and/or addiction problems. The job description provided in this article may not be appropriate for all settings, but it will contribute to a better understanding of the peer support worker position, the skills required, and the types of expectations that could define successful fulfillment of the role
