Jewish quotas in clinical psychology?: The Journal of Clinical Psychology and the scandal of 1945.

In 1945 Frederick Thorne, editor of the Journal of Clinical Psychology, proposed to limit the acceptance of Jewish applicants to clinical psychology graduate schools. A public scandal erupted over this proposed limit, which was modeled on Jewish quotas in medical education. Criticized by the mass media and most psychologists, Thorne’s proposal was repudiated by the Eastern Psychological Association and the Society for the Psychological Study of Social Issues. Using private correspondence, oral histories, and published articles, this mostly forgotten episode in the history of clinical psychology is recreated. It is argued that the 1945 campaign against Jewish quotas prepared activists for the 1950s campaign against racial segregation and the Brown v. Board of Education Supreme Court case. Because the participants in 1945 came from all specialties in psychology, it is suggested that this story is of significance to the field as a whole, rather than just to historians of social issues.

Prognostics and Health Management of PEMFC – State of the art and remaining challenges

Fuel Cell systems (FC) represent a promising alternative energy source. However, even if this technology is close to being competitive, it is not ready for large scale industrial deployment: FC still must be optimized, particularly by increasing their limited lifespan. This involves a better understanding of wearing processes and requires emulating the behavior of the whole system. Furthermore, a new area of science and technology emerges: Prognostics and Health Management (PHM) appears to be of great interest to face the problems of health assessment and life prediction of FCs. According to this, the aim of this paper is to present the current state of the art on PHM of FCs, more precisely of Proton-Exchange Membrane Fuel Cells (PEMFC) stack. PHM discipline is described in order to depict the processing layers that allow early deviations detection, avoiding faults, deciding mitigation actions, and thereby increasing the useful life of FCs. On this basis, a taxonomy of existing works on PHM of PEMFC is given, highlighting open problems to be addressed. The whole enables getting a better understanding of remaining challenging issues in this area.     

矿业权价款评估管理问题与对策研究

论文采用专家访谈、实地调研和问卷调查等方法,揭示出当前我国矿业权价款评估管理过程中存在的突出问题,包括评估管理的依据标准化不够、评估管理的流程不尽完善、评估管理的程序规范化不够、监督管理模式不适宜等。改革矿业权价款评估管理的主要措施包括:回归矿业权价款法定概念,规范矿业权价款征收与评估范围;简政放权、转变职能,处理好中央与地方、政府与市场的关系;优化矿业权价款评估管理流程;完善矿业权价款评估管理程序;改革、完善矿业权价款评估监督管理模式。     

Bridge management issues in a large agency

With over 20,000 employees, an annual budget of approximately US$10 billion and the Maintenance and Operations responsibility for over 58,000 lane-miles of highway and over 12,000 bridges, the California Department of Transportation is by most measures a large agency. To be effective, management decisions must constantly assess the tradeoffs between many competing interests and conform to numerous constraints. This paper discusses many of these issues and their effects on decisions made to manage the state bridge inventory from a practitioner's point of view.     

Environmental health concepts and issues — a viewpoint

The quality of our environment and the effect of environmental agents on our health depend largely on the policies adopted by the international community and governments. Global environmental problems pose a threat to human health and well‐being; but all the world's countries which must act co‐operatively to find measures to address such issues have their particular conceptual and diverse environmental challenges. Several concepts have been developed worldwide to show how environmental issues are increasingly central to our health. This paper addresses some of these concepts as they are relevant to us today and in the future.     

Challenges and future developments in proton exchange membrane fuel cells

Fuel cell system is an advanced power system for the future that is sustainable, clean and environmental friendly. The importance of fuel cell as the future power system is discussed in the light of future fossil fuel depletion, impending international law on green house gases control and the national renewable energy policy. The modern development of the proton exchange membrane fuel cell (PEMFC) for the last 20 years is then briefly reviewed and the current status of international and national research and development of this type of are established. The review also discuss the remaining research and development issues that still need to be resolved before these fuel cells are available for commercial application. The main thrust in PEMFC research and development is to lower the cost of the fuel cell by reduction in membrane and electrocatalyst costs. Although Europe, USA, Canada and Japan are leading fuel cell research and development as commercialization, it is not too late for Malaysia to master this technology and to apply it to niche markets in the future.     

The SPSSI Statement on Academic Freedom.

In September 19S3 the SPSSI Council approved the formation of a committee to develop a policy statement which might serve as a guide for the Society's efforts in behalf of academic freedom. In February 1954 the Council adopted a statement (Statement on the Relation of Investigating Committee to Academic and Scientific Freedom), which was then mailed to all members for a referendum vote.

The ethical challenges and issues of online journalism practice in Nigeria: What do professionals and academics think?

This study evaluated the ethical challenges and issues of online media in Nigeria. The study used a mixed research method. Data were collected from journalists in Jalingo and lecturers of Mass Communication in one public University. The quantitative data were analysed using SPSS version 25. While the qualitative data collected via interviews were analysed thematically. Both data suggest there is a high rate of unethical practices in online media in Nigeria. Fake news was ranked first, while other issues such as a lack of objectivity, lack of decency, invasion of privacy, hate speeches and sensationalism were found to be common in online media practice. Furthermore, the study found that desire to break news, lack of professional training and regulation, and political interest were key factors encouraging unethical practices in online media. The study also established that unethical practices among online media can be checkmated if online media practitioners are also regulated by licensing and exposed to training. Thus, the study recommended among others that the Nigeria Communication Commission should work with internet service providers and Telecommunication companies to design a model that will ensure that online media are registered before they can operate. Telecommunication companies and service providers should block online media that are known for perpetrating unethical practices.
