The More Things Change, The More They Stay the Same: Educational and Disciplinary Backgrounds of American Librarians, 1950-2015

Discussions of diversity in American librarianship usually focus on gender or ethnicity, but historical studies also show a lack of diversity in educational and disciplinary backgrounds. Librarians traditionally hail from the humanities, especially English and history. But as current educational attention shifts to science, technology, engineering and math (STEM) fields, are librarians reflecting this change? Anonymized data from ALA-accredited graduate programs from the last five years was collected, coded, and classified to determine librarians’ educational and disciplinary backgrounds and in what ways, if any, they differ from the past 65 years and from the contemporary U.S. general population. Unsurprisingly, we found that contemporary librarians still hail predominantly from English and history—a stark contrast from the business and health undergraduate degrees earned by the general U.S. population. Backgrounds in STEM fields remain lacking in librarianship, but librarians with undergraduate education in the arts are on the rise, perhaps supporting the creativity, flexibility, innovation and risk-taking necessary in 21st century libraries

Training, status and migration of general practitioners / family physicians within Europe

The survey intended to explore and identify the training background and status of general practitioners/ family physicians (GPs) in member countries within EURACT (European Academy of Teachers in General Practice/Family Medicine), and to gain an overview of processes involved when GP-trained doctors migrate to work in another member country. A questionnaire, with closed and open-ended questions, was sent to representatives of all 39 EURACT-member countries in 2009. The main outcome measures were the training background and status of GPs in public/private settings in each country and the requirements of additional training and testing when migrating to another country. Forty-one completed questionnaires were received from 31 (79%) of the EURACT countries. The data indicate that specialist training for General Practice/ Family Medicine (GP/FM) is well established throughout and generally required for appointment to public career posts. The data also indicate that European Uniontrained GPs can move freely to most countries with usually no tests of medical knowledge or language proficiency. Orientation to the healthcare system in the destination country is usually not provided. work in public/private GP/FM posts in many European countries, although new appointments to public posts RESEARCH ARTICLE Training, status and migration of General Practitioners/Family Physicians within Europe in nearly all countries require specialist GP training. It was not possible to identify a uniform or agreed approach applied by employing agencies to confirm the medical competence and language skills of migrant doctors and to provide them with orientation to healthcare systems. In the high-context dependent discipline of GP/FM this is of concern.peer-reviewe

Bioavailability of Glucoraphanin and Sulforaphane From High-Glucoraphanin Broccoli

Scope: Broccoli accumulates 4-methylsulphinylbutyl glucosinolate (glucoraphanin) which is hydrolyzed to the isothiocyanate sulforaphane. Through the introgression of novel alleles of the Myb28 transcription factor from Brassica villosa, broccoli genotypes have been developed that have enhanced levels of glucoraphanin. This study sought to quantify the exposure of human tissues to glucoraphanin and sulforaphane following consumption of broccoli with contrasting Myb28 genotypes. Methods and results: Ten participants were recruited into a three-phase, double-blinded, randomized crossover trial (NCT02300324), with each phase comprising consumption of 300 ml of a soup made from broccoli of one of three Myb28 genotypes (Myb28B/B, Myb28B/V, Myb28V/V). Plant myrosinases were intentionally denatured during soup manufacture. Three-fold and five-fold higher levels of sulforaphane occurred in the circulation following consumption of Myb28V/B and Myb28V/V broccoli soups, respectively. The percentage of sulforaphane excreted in 24 h relative to the amount of glucoraphanin consumed varied amongst volunteers from 2% to 15%, but did not depend on the broccoli genotype. Conclusion: This is the first study to report the bioavailability of glucoraphanin and sulforaphane from soups made with novel broccoli varieties. The presence of one or two Myb28V alleles results in enhanced delivery of sulforaphane to the systemic circulation

3D UK? 3D History and the Absent British Pioneers

The recent television ‘rediscovery’ of a small cohort of 1950s British 3D films (and the producers who made them) has offered a new route into considering how the historical stories told about 3D film have focused almost exclusively on the American experience, eliding other national contexts. This article challenges both the partiality of existing academic histories of 3D, and the specific popular media narratives that have been constructed around the British 3D pioneers. Offering a rebuttal of those narratives and an expansion of them based around primary archival research, the article considers how the British 3D company Stereo Techniques created a different business and production model based around non-fiction short 3D films that stand in contrast to the accepted view of 3D as an American feature film novelty. Through an exploration of the depiction (and absence) of these 3D pioneers from existing media histories, the article argues for a revision to both 3D studies and British cinema history

A descriptive survey study of violence management and priorities among psychiatric staff in mental health services, across seventeen european countries.

BACKGROUND: In mental health services what is commonplace across international frontiers is that to prevent aggressive patients from harming themselves, other patients or staff, coercive measures and foremost, violence management strategies are required. There is no agreement, recommendations or direction from the EU on which measures of coercion should be practiced across EU countries, and there is no overall one best practice approach. METHODS: The project was conceived through an expert group, the European Violence in Psychiatry Research Group (EViPRG). The study aimed to incorporate an EU and multidisciplinary response in the determination of violence management practices and related research and education priorities across 17 European countries. From the EVIPRG members, one member from each country agreed to act as the national project coordinator for their country. Given the international spread of respondents, an eDelphi survey approach was selected for the study design and data collection. A survey instrument was developed, agreed and validated through members of EVIPRG. RESULTS: The results included a total of 2809 respondents from 17 countries with 999 respondents who self-selected for round 2 eDelphi. The majority of respondents worked in acute psychiatry, 54% (n = 1511); outpatient departments, 10.5% (n = 295); and Forensic, 9.3% (n = 262). Other work areas of respondents include Rehabilitation, Primary Care and Emergency. It is of concern that 19.5% of respondents had not received training on violence management. The most commonly used interventions in the management of violent patients were physical restraint, seclusion and medications. The top priorities for education and research included: preventing violence; the influence of environment and staff on levels of violence; best practice in managing violence; risk assessment and the aetiology and triggers for violence and aggression. CONCLUSION: In many European countries there is an alarming lack of clarity on matters of procedure and policy pertaining to violence management in mental health services. Violence management practices in Europe appear to be fragmented with no identified ideological position or collaborative education and research. In Europe, language differences are a reality and may have contributed to insular thinking, however, it must not be seen as a barrier to sharing best practice

The market efficiency in the stock markets

We study the temporal evolution of the market efficiency in the stock markets using the complexity, entropy density, standard deviation, autocorrelation function, and probability distribution of the log return for Standard and Poor's 500 (S&P 500), Nikkei stock average index, and Korean composition stock price index (KOSPI). Based on the microscopic spin model, we also find that these statistical quantities in stock markets depend on the market efficiency.Comment: 8 pages, 5 figure

Bmi-1 is required for maintenance of adult self-renewing haematopoietic stem cells

A central issue in stem cell biology is to understand the mechanisms that regulate the self-renewal of haematopoietic stem cells (HSCs), which are required for haematopoiesis to persist for the lifetime of the animal(1). We found that adult and fetal mouse and adult human HSCs express the proto-oncogene Bmi-1. The number of HSCs in the fetal liver of Bmi-1(-/-) mice(2) was normal. In postnatal Bmi-1(-/-) mice, the number of HSCs was markedly reduced. Transplanted fetal liver and bone marrow cells obtained from Bmi-1(-/-) mice were able to contribute only transiently to haematopoiesis. There was no detectable self-renewal of adult HSCs, indicating a cell autonomous defect in Bmi-1(-/-) mice. A gene expression analysis revealed that the expression of stem cell associated genes(3), cell survival genes, transcription factors, and genes modulating proliferation including p16(Ink4a) and p19(Arf) was altered in bone marrow cells of the Bmi-1(-/-) mice. Expression of p16(Ink4a) and p19(Arf) in normal HSCs resulted in proliferative arrest and p53-dependent cell death, respectively. Our results indicate that Bmi-1 is essential for the generation of self-renewing adult HSCs.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62508/1/nature01587.pd

The impact of predation by marine mammals on Patagonian toothfish longline fisheries

Predatory interaction of marine mammals with longline fisheries is observed globally, leading to partial or complete loss of the catch and in some parts of the world to considerable financial loss. Depredation can also create additional unrecorded fishing mortality of a stock and has the potential to introduce bias to stock assessments. Here we aim to characterise depredation in the Patagonian toothfish (Dissostichus eleginoides) fishery around South Georgia focusing on the spatio-temporal component of these interactions. Antarctic fur seals (Arctocephalus gazella), sperm whales (Physeter macrocephalus), and orcas (Orcinus orca) frequently feed on fish hooked on longlines around South Georgia. A third of longlines encounter sperm whales, but loss of catch due to sperm whales is insignificant when compared to that due to orcas, which interact with only 5% of longlines but can take more than half of the catch in some cases. Orca depredation around South Georgia is spatially limited and focused in areas of putative migration routes, and the impact is compounded as a result of the fishery also concentrating in those areas at those times. Understanding the seasonal behaviour of orcas and the spatial and temporal distribution of “depredation hot spots” can reduce marine mammal interactions, will improve assessment and management of the stock and contribute to increased operational efficiency of the fishery. Such information is valuable in the effort to resolve the human-mammal conflict for resources

Gender (in)equity in global mental health research: A call to action.

In this commentary, we build on work by Gurung and colleagues which highlighted gender inequity in the global mental health research workforce in Nepal (Gurung et al., 2021). We seek to increase awareness of the under-representation of women in global mental health research and its consequences, and we call for change. By women, we refer to all people who identify as women, including trans people. The commentary is informed by conversations with women who are global mental health researchers in the Global North and South at various stages of their careers

Light-Driven H2 Evolution and C═C or C═O Bond Hydrogenation by Shewanella oneidensis : A Versatile Strategy for Photocatalysis by Nonphotosynthetic Microorganisms

Photocatalytic chemical synthesis by coupling abiotic photosensitizers to purified enzymes provides an effective way to overcome the low conversion efficiencies of natural photosynthesis while exploiting the high catalytic rates and selectivity of enzymes as renewable, earth-abundant electrocatalysts. However, the selective synthesis of multiple products requires more versatile approaches and should avoid the time-consuming and costly processes of enzyme purification. Here we demonstrate a cell-based strategy supporting light-driven H2 evolution or the hydrogenation of C═C and C═O bonds in a nonphotosynthetic microorganism. Methylviologen shuttles photoenergized electrons from water-soluble photosensitizers to enzymes that catalyze H2 evolution and the reduction of fumarate, pyruvate, and CO2 in Shewanella oneidensis. The predominant reaction is selected by the experimental conditions, and the results allow rational development of cell-based strategies to harness nature’s intrinsic catalytic diversity for selective light-driven synthesis of a wide range of products
