South Africa’s Psychiatric training capacity in 2008 and in 2018. Has training capacity improved?

Background: There is a deficit of psychiatrists in South Africa, and to our knowledge, there is no situational analysis of training posts for psychiatrists in the country. Aim: To compare the number of specialists and subspecialists in training and training posts available in 2008 and 2018. Setting: South African medical schools with departments of psychiatry. Methods: A situational analysis involving data collection through a survey completed by eight heads of academic psychiatric departments followed by a comparative analysis of the two aforementioned years. Results: Data shows an 11% increase in funded and unfunded posts combined and a 9.3% increase in funded posts. The occupancy of funded posts decreased (92% in 2008 to 82% in 2018). When considering both funded and unfunded posts, only three more psychiatrists were being trained in 2018. Supernumeraries appointed in unfunded posts can be expected to return to their countries of origin. As such, a decrease in filled funded posts likely reflects a decrease in training psychiatrists destined to work in South Africa. While child and adolescent psychiatry was the only sub-speciality with accredited training posts in 2008, all sub-specialities included on the questionnaire had accredited training posts in 2018, and the number of accredited training posts in child and adolescent psychiatry doubled. That said, many of the posts were unfunded and vacant. Conclusion: While there was an increase in posts from 2008 to 2018, many posts remained unfilled. As such, not only are additional funded training posts required but also strategies to increase post-occupancy and successful completion of training. Contribution: This study is the first situational analysis of specialist and subspecialist training posts in Psychiatry in South Africa, at two time points over a 10 year period, that draws on academic heads of departments of psychiatry as respondents. The study highlights the nominal increase in funded training posts over this period, especially subspecialist training posts. The majority of Health Professions Council of South Africa (HPCSA) accredited subspecialities in Psychiatry have no funded training posts which is particularly concerning

Persistence of Monopoly and Research Specialization

We examine the persistence of monopolies in markets with innovations when the outcome of research is uncertain. We show that for low success probabilities of research, the incumbent can seldom preempt the potential entrant. Then the efficiency effect outweighs the replacement effect. It is vice versa for high probabilities. Moreover, the incumbent specializes in safe research and the potential entrant in risky research. We also show that the probability of entry has an inverted U-shape in the success probability. Since even at the peak entry is rather unlikely, the persistence of the monopoly is high

What Every Business Student Needs to Know About Information Systems

Whether Information Systems should or should not be part of the core business school curriculum is a recurring discussion in many universities. In this article, a task force of 40 prominent information systems scholars address the issue. They conclude that information systems is absolutely an essential body of knowledge for business school students to acquire as well as a key element of the business school\u27s long-run strategic positioning within the university. Originally prepared in response to draft accreditation guidelines prepared by AACSB International, the article includes a compilation of the concepts that the authors believe to be the core information systems knowledge that all business school students should be familiar with

Roadmap on Photovoltaic Absorber Materials for Sustainable Energy Conversion

Photovoltaics (PVs) are a critical technology for curbing growing levels of anthropogenic greenhouse gas emissions, and meeting increases in future demand for low-carbon electricity. In order to fulfil ambitions for net-zero carbon dioxide equivalent (CO2eq) emissions worldwide, the global cumulative capacity of solar PVs must increase by an order of magnitude from 0.9 TWp in 2021 to 8.5 TWp by 2050 according to the International Renewable Energy Agency, which is considered to be a highly conservative estimate. In 2020, the Henry Royce Institute brought together the UK PV community to discuss the critical technological and infrastructure challenges that need to be overcome to address the vast challenges in accelerating PV deployment. Herein, we examine the key developments in the global community, especially the progress made in the field since this earlier roadmap, bringing together experts primarily from the UK across the breadth of the photovoltaics community. The focus is both on the challenges in improving the efficiency, stability and levelized cost of electricity of current technologies for utility-scale PVs, as well as the fundamental questions in novel technologies that can have a significant impact on emerging markets, such as indoor PVs, space PVs, and agrivoltaics. We discuss challenges in advanced metrology and computational tools, as well as the growing synergies between PVs and solar fuels, and offer a perspective on the environmental sustainability of the PV industry. Through this roadmap, we emphasize promising pathways forward in both the short- and long-term, and for communities working on technologies across a range of maturity levels to learn from each other.Comment: 160 pages, 21 figure

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Status, Happiness and Relative Income

Models of status based on Frank\u27s (1985) count of the number of people with lower conspicuous consumption are inconsistent with the extensive empirical literature on happiness and well-being. The alternative approach to consumption interaction which uses some form of relative income has been developed in various contexts. These predict that a representative agent\u27s well-being will increase with real income or consumption. However, this is again inconsistent with the time-series evidence for advanced economies. In this paper we combine a simple model of relative income with a distribution of ability that correctly predicts both time series results of near constant utility, and the positive, concave crosssectional relation between income, working time and happiness
