Pre-Hire Factors and Workplace Ethnic Segregation

In addition to neighbourhoods of residence, family and places of work play important roles in producing and reproducing ethnic segregation. Therefore, recent research on ethnic segregation and contact is increasingly turning its attention from residential areas towards other important domains of daily interethnic contact. The key innovation of this paper is to clarify the role of immigrants' pre-hire exposure to natives in the residence, workplace and family domains in immigrant exposure to natives in their current workplace. The study is based on Swedish population register data. The results show that at the macro level, workplace neighbourhood segregation is lower than residential neighbourhood segregation. Our micro-level analysis further shows that high levels of residential exposure of immigrants to natives help to reduce ethnic segregation at the level of workplace establishments as well.neighbourhood effects, residential segregation, workplace segregation, intermarriage, longitudinal analysis, Sweden

Avulsion fractures of the ischial tuberosity-thorough diagnostics for complications prevention

Złamania awulsyjne stanowią jedno z możliwych następstw nadmiernej eksploatacji narządu ruchu. Powstają w wyniku silnego skurczu mięśnia lub niefizjologicznego ruchu stawu, gdy ścięgno lub więzadło wyrywa fragment kostny. Objawy złamania awulsyjnego guza kulszowego obejmują wystąpienie silnego bólu w miejscu uszkodzenia z uczuciem trzasku oraz ograniczeniem mobilności kończyny. Ze względu na zbliżone objawy kliniczne, złamanie to jest często nieprawidłowo diagnozowane jako uszkodzenie mięśni kulszowo-goleniowych. Postawienie błędnej diagnozy może wiązać się z podjęciem nieprawidłowego planu terapeutycznego, co może skutkować przedłużonym okresem rekonwalescencji czy gorszą końcową sprawnością kończyny. Studium przypadku* opisuje młodocianego piłkarza u którego złamanie awulsyjne guza kulszowego zostało początkowo rozpoznane jako naciągnięcie mięśnia dwugłowego uda. Ze względu na brak zadowalających wyników leczenia oraz przewlekłe dolegliwości bólowe okolicy pośladkowej u pacjenta, 12 miesięcy po urazie wykonano RTG miednicy, które uwidoczniło przemieszczony odłam nasady guza kulszowego bez cech zrostu. Po 16 miesiącach od urazu, zdecydowano się na operacyjne zespolenia złamania. Przypadek ten podkreśla wagę prawidłowo wykonanego badania fizykalnego oraz przeprowadzenia dokładnej diagnostyki różnicowej uszkodzeń aparatu ruchu, szczególnie u osób młodych. Celem pracy jest przedstawienie współczesnego postępowania diagnostycznego i terapeutycznego złamań awulsyjnego w obrębie guza kulszowego.Avulsion fractures are one of the potential illnesses that may be a result of the overexploitation of the locomotor system. They are caused by excessive stretching forces present during uncoordinated muscle spasm or non-physiological articular movement when tendon or ligament pull the bone fragment. The main symptoms of avulsion fracture of the ischial tuberosity include a sudden onset of strong pain accompanied by a feeling of crackling or the decreased mobility of the limb. Due to similar clinical indicators, it is often misdiagnosed as damaged ligaments of the two-headed thigh muscle. This may lead to the introduction of a suboptimal treatment plan, with a prolonged convalescence period or deprived limb ability. This study describes a case of a young soccer player who suffered from an ischial tuberosity avulsion fracture that was misdiagnosed as a torn of the two-headed thigh muscle. Due to the prolonged recovery period, an MR scan was performed 12 months after the incident revealing a non-union displaced avulsion fracture of the ischial tuberosity. After 16 months of unsuccessful conservative treatment, surgical fixation of the fracture was performed. This case underlines the value of both physical examination and thorough differential diagnosis of motor system injuries, especially in cases of younger patients. Proper and quick implementation of treatment minimizes the effects of an injury. Chronic hip pain, especially in young athletes, cannot be underestimated. The article aims to present the current state of knowledge about the diagnosis and treatment of avulsion fracture of the ischial tuberosity

SHEER “smart” database: technical note

The SHEER database brings together a large amount of data of various types: interdisciplinary site data from seven independent episodes, research data and those for the project results dissemination process. This concerns mainly shale gas exploitation test sites, processing procedures, results of data interpretation and recommendations. The smart SHEER database harmonizes data from different fields (geophysical, geochemical, geological, technological, etc.), creates and provides access to an advanced database of case studies of environmental impact indicators associated with shale gas exploitation and exploration, which previously did not exist. A unique component of the SHEER database comes from the monitoring activity performed during the project in one active shale gas exploration and exploitation site at Wysin, Poland, which started from the pre-operational phase. The SHEER database is capable of the adoption of new data such as results of other Work Packages and has developed an over-arching structure for higher-level integration

Global maps of soil temperature

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic variables at a 1-km2 resolution for 0–5 and 5–15 cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1-km2 pixels (summarized from 8519 unique temperature sensors) across all the world\u27s major terrestrial biomes, and coarse-grained air temperature estimates from ERA5-Land (an atmospheric reanalysis by the European Centre for Medium-Range Weather Forecasts). We show that mean annual soil temperature differs markedly from the corresponding gridded air temperature, by up to 10°C (mean = 3.0 ± 2.1°C), with substantial variation across biomes and seasons. Over the year, soils in cold and/or dry biomes are substantially warmer (+3.6 ± 2.3°C) than gridded air temperature, whereas soils in warm and humid environments are on average slightly cooler (−0.7 ± 2.3°C). The observed substantial and biome-specific offsets emphasize that the projected impacts of climate and climate change on near-surface biodiversity and ecosystem functioning are inaccurately assessed when air rather than soil temperature is used, especially in cold environments. The global soil-related bioclimatic variables provided here are an important step forward for any application in ecology and related disciplines. Nevertheless, we highlight the need to fill remaining geographic gaps by collecting more in situ measurements of microclimate conditions to further enhance the spatiotemporal resolution of global soil temperature products for ecological applications

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
