Elite formation in the higher education systems of Ireland and the UK: Measuring, comparing and decomposing longitudinal patterns of cabinet members.

The role of higher education systems in the formation and reproduction of governing elites, and their countervailing potential for the creation of a more egalitarian, or meritocratic, society has been an enduring subject of concern, debate and research. Many of these debates are made all the more difficult by our inability to directly compare elite formation systems within and between countries and over time. To resolve these problems, this paper employs elite formation quantitative indices to directly and transparently compare elite formation systems, namely the role of higher education systems in political elite formation over three quarters of a century in two countries. Specifically, the paper compares the influence, exclusiveness and eliteness of the Irish and British higher education systems in the production of their respective governing political elites in the 75 years between 1937 and 2012

The Self and Other: Portraying Israeli and Palestinian Identities on Twitter

The conflict between Israel and Palestine has lasted over half a century, with both sides enduring military and political turmoil. This paper explores how Twitter is being used as a medium to portray identities in the conflict. We examine the tweets contained in the @IDFspokesperson and @ISMPalestine Twitter accounts between late 2015 and early 2016. Using textual analysis, we gain an insight into how these Twitter accounts, defined by the conflict, are used in portraying the self and the other

Autofluorescence in eleocytes of some earthworm species.

Immunocompetent cells of earthworms, coelomocytes, comprise adherent amoebocytes and granular eleocytes (chloragocytes). Both cell populations can be expelled via dorsal pores of adult earthworms by exposure to an electric current (4.5 V) for 1 min. Analysis by phase contrast/fluorescence microscopy and flow cytometry demonstrated that eleocyte population of several species exhibits a strong autofluorescence. A high percentage (11-35%) of autofluorescent eleocytes was recorded in Allolobophora chlorotica, Dendrodrilus rubidus, Eisenia fetida, and Octolasion sp. (O. cyaneum, O. tyrtaeum tyrtaeum and O. tyrtaeum lacteum). In contrast, autofluorescent coelomocytes were exceptionally scarce (less than 1%) in representative Aporrectodea sp. (A. caliginosa and A. longa) and Lumbricus sp. (L. castaneus, L. festivus, L. rubellus, L. terrestris). Thus, this paper for the first time describes profound intrinsic fluorescence of eleocytes in some--but not all--earthworm species. The function (if any) and inter-species differences of the autofluorescent coelomocytes still remain elusive

A comparison of on-line and off-line bioaerosol measurements at a biowaste site

An air measurement campaign was carried out at a green-waste composting site in the South of Ireland during Spring 2016. The aim was to quantify and identify the levels of Primary Biological Aerosol Particles (PBAP) that were present using the traditional off-line, impaction/optical microscopy method alongside an on-line, spectroscopic approach termed WIBS (Wideband Integrated Bioaerosol Sensor), which can provide number concentrations, sizes and “shapes” of airborne PBAP in real-time by use of Light Induced Fluorescence (LIF). The results from the two techniques were compared in order to validate the use of the spectroscopic method for determining the releases of the wide-range of PBAP present there as a function of site activity and meteorological conditions. The seven-day monitoring period undertaken was much longer than any real-time studies that have been previously performed and allowed due comparison between weekday (working) activities at the site and weekend (closed) releases. The time-span also allowed relationships between site activities like turning, agitation or waste delivery and the WIBS data to be determined in a quantitative manner. This information cannot be obtained with the Andersen Sampling methods generally employed at green-waste management sites. Furthermore, few specific bioaerosol types other than Aspergillus fumigatus, are identified using the traditional protocols employed for site licensing purposes. Here though the co-location of WIBS with the impaction instrument made it possible to identify the real-time release behaviour of a specific plant pathogenic spore, Ustilago maydis, present after green-waste deliveries were made by a local distillery

Life after lockdown: Zooming out on perceptions in the post-videoconferencing era

Background: The COVID-19 pandemic has deeply disrupted daily life across the globe, with profound effects on mental and physical health. After more than a year of isolation and communication via videoconferencing, people are returning to in-person activities. Objective: This study aimed to investigate worsening self-perception, mental health, and anxiety with the return to in-person activities, with a focus on the influence of videoconferencing, social media, and the use of filters. Methods: An anonymous survey was distributed online through social media platforms and student network pages. Results: A total of 7295 participants responded to the survey. Seventy-one precent reported anxiety or stress related to returning to in-person activities, and nearly 64% sought mental health support services. Thirty-percent stated they plan to invest in their appearance as a coping strategy to deal with the anxiety of returning to in-person, and \u3e 30% plan to take action in changing their appearance. The most reported dermatologic concerns were skin discoloration (32.36%), wrinkles (24.45%), and acne (14.85%). The prevalence of anxiety and mental health services increased relative to the use of filters in 18- to 24 year-olds. Conclusion: This survey study of \u3e 7000 participants across the country elucidates worsening self-perception, anxiety, and mental health as we return to in-person activities in relation to increased videoconferencing, social media usage, and the use of filters. Physicians should be aware of these effects to better serve their patients

False positive HIV diagnoses in resource limited settings: operational lessons learned for HIV programmes

Access to HIV diagnosis is life-saving; however the use of rapid diagnostic tests in combination is vulnerable to wrongly diagnosing HIV infection when both screening tests give a false positive result. Misclassification of HIV patients can also occur due to poor quality control, administrative errors and lack of supervision and training of staff. Médecins Sans Frontières discovered in 2004 that HIV negative individuals were enrolled in some HIV programmes. This paper describes the result of an audit of three sites to review testing practices, implement improved testing algorithms and offer re-testing to clients enrolled in the HIV clinic

ICON 9-an international phase III randomized study to evaluate the efficacy of maintenance therapy with olaparib and cediranib or olaparib alone in patients with relapsed platinum-sensitive ovarian cancer following a response to platinum-based chemotherapy

BACKGROUND: Two novel biological agents-cediranib targeting angiogenesis, and olaparib targeting DNA repair processes-have individually led to an improvement in ovarian cancer control. The aim of ICON9 is to investigate the combination of cediranib and olaparib maintenance in recurrent ovarian cancer following platinum-based therapy. PRIMARY OBJECTIVE: To assess the efficacy of maintenance treatment with olaparib in combination with cediranib compared with olaparib alone following a response to platinum-based chemotherapy in women with platinum-sensitive ovarian, fallopian tube or peritoneal cancer during first relapse. STUDY HYPOTHESIS: Maintenance therapy with cediranib and olaparib in combination is associated with improved patient outcomes compared with olaparib alone. TRIAL DESIGN: International phase III randomized controlled trial. Following a response to platinum-based chemotherapy patients are randomized 1:1 to either oral olaparib and cediranib (intervention arm) or oral olaparib alone (control arm). MAJOR INCLUSION CRITERIA: Patients with a known diagnosis of high grade serous or endometrioid carcinoma of the ovary, fallopian tube or peritoneum, progressing more than 6 months after first-line platinum-based chemotherapy, who have responded to second-line platinum-based chemotherapy. PRIMARY ENDPOINTS: Progression-free and overall survival. Co-primary endpoints to be assessed using a fixed-sequence gatekeeping approach: (1) progression-free survival, all patients; (2) progression-free survival, BRCA wild type; (3) overall survival, all patients; (4) overall survival, BRCA wild type. SAMPLE SIZE: 618 patients will be recruited. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Accrual is expected to be completed in 2024 with presentation of results in 2025. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03278717

Early Ultraviolet Observations of Type IIn Supernovae Constrain the Asphericity of Their Circumstellar Material

© 2020. The American Astronomical Society. All rights reserved.. We present a survey of the early evolution of 12 Type IIn supernovae (SNe IIn) at ultraviolet and visible light wavelengths. We use this survey to constrain the geometry of the circumstellar material (CSM) surrounding SN IIn explosions, which may shed light on their progenitor diversity. In order to distinguish between aspherical and spherical CSM, we estimate the blackbody radius temporal evolution of the SNe IIn of our sample, following the method introduced by Soumagnac et al. We find that higher-luminosity objects tend to show evidence for aspherical CSM. Depending on whether this correlation is due to physical reasons or to some selection bias, we derive a lower limit between 35% and 66% for the fraction of SNe IIn showing evidence for aspherical CSM. This result suggests that asphericity of the CSM surrounding SNe IIn is common - consistent with data from resolved images of stars undergoing considerable mass loss. It should be taken into account for more realistic modeling of these events
