Early career consequences of temporary employment in Germany and the UK
This article investigates the effects of temporary employment at labour market entry on subsequent individual careers, drawing on data from the British Household Panel Study (BHPS) and the German Socio-Economic Panel (GSOEP) from the period 1991 to 2007. The results show that German temporarily employed entrants suffer from higher initial wage penalties and risks of temporary employment cycles but that all differences compared to entrants with permanent contracts diminish after five years. The integration scenario works more effectively in the UK, where disadvantages are less pronounced and employment losses are primarily related to further education. Moreover, these tendencies vary by education groups and gender. Disadvantages of initial temporary employment are weaker for women in Germany, while gender differences in the UK apparently have less impact. Across borders, temporary contracts are associated with greater initial but vanishing wage penalties and temporary employment cycles for tertiary graduates.

Changes in Income Poverty Risks at the Transition from Unemployment to Employment: Comparing the Short-Term and Medium-Term Effects of Fixed-Term and Permanent Jobs
Unemployment is a major risk factor of poverty and employment is regarded key to overcoming it. The present study examines how the income poverty risk of unemployed individuals changes in the short and medium term, when they take up work, and whether the effects differ according to the type of employment. The focus is on permanent and fixed-term job contracts, as the political promotion of fixed-term employment has often been framed as an effort to reduce long-term unemployment and poverty. Drawing on longitudinal data from the German panel study ‘Labour Market and Social Security’ (PASS) 2010–18, we apply a first difference estimator with asymmetric effects to examine the effect of starting a job out of unemployment on income poverty risks in the subsequent four years. Strikingly, starting in a fixed-term and permanent contract have similarly strong and lasting poverty-reducing effects in the short and medium term. Thus, with regard to risks of income poverty, starting a permanent job does not appear more beneficial than starting a fixed-term job for unemployed persons. We discuss the reasons for this finding and also explore how the poverty-reducing effects of transitions from unemployment to fixed-term versus permanent employment vary by household type, occupation, working time and firm size.

Young Women’s Transition from Education to Work in the Caucasus and Central Asia
This article analyzes the individual- and family-level factors that pave the way to the labor market and to formal sector jobs for young women in the Caucasus and Central Asia. Retrospective life history data from a 2017 survey in Azerbaijan, Georgia, and Tajikistan show that higher education attainment has a strong positive impact on labor market activity and getting a formal sector job. Early family formation drives young women into inactivity, but it does not limit the chances of getting access to the formal sector. The chances of getting a formal sector job are positively influenced by the social resources of parents in Georgia and Tajikistan and by parents’ economic resources in Azerbaijan and Georgia. Evidence about the role of economic need and of traditionalism for women’s labor market participation is mixed.

Does Deregulation Help? The Impact of Employment Protection Reforms on Youths' Unemployment and Temporary Employment Risks in Europe
Rigid employment protection legislation (EPL) has been blamed as the root of youths' labour market integration problems in Europe. Many European countries have reacted by deregulating employment protection laws, often targeting youths as a group. However, doubts about the effectiveness of EPL reforms have arisen. Against this background, this article investigates whether EPL reforms succeeded in integrating youths into labour markets or whether they were ineffective and just promoted temporary employment as a crucial new social inequality in Europe. Based on two-step, three-level analyses using micro-data from the European Labour Force Survey for 19 European countries for the period from 1992 to 2012, our results show that deregulating the use of temporary contracts increased temporary employment risks of youths but did not reduce (for low-educated young men, even increased) unemployment risks. In contrast, we find some evidence that decreasing the protection of permanent jobs was successful in decreasing risks of inequality/insecurity (in terms of temporary jobs) without affecting the risks of labour market exclusion.

Use of Monitoring Approaches to Verify the Predictive Accuracy of the Modeling of Particle-Bound Solid Inputs to Surface Waters
For particle-bound substances such as phosphorus, erosion is an important input pathway to surface waters. Therefore, knowledge of soil erosion by water and sediment inputs to water bodies at high spatial resolution is essential to derive mitigation measures at the regional scale. Models are used to calculate soil erosion and associated sediment inputs to estimate the resulting loads. However, validation of these models is often not sufficiently possible. In this study, sediment input was modeled on a 10 × 10 m grid for a subcatchment of the Kraichbach river in Baden-Wuerttemberg (Germany). In parallel, large-volume samplers (LVS) were operated at the catchment outlet, which allowed a plausibility check of the modeled sediment inputs. The LVS produced long-term composite samples (2 to 4 weeks) over a period of 4 years. The comparison shows a very good agreement between the modeled and measured sediment loads. In addition, the monitoring concept of the LVS offers the possibility to identify the sources of the sediment inputs to the water body. In the case of the Kraichbach river, it was found that around 67% of the annual sediment load in the water body is contributed by rainfall events and up to 33% represents dry-weather load. This study shows that the modeling approaches for calculating the sediment input provide good results for the test area Kraichbach and the transfer for a German wide modeling will produce plausible values.

Testosterone-receptor positive hepatocellular carcinoma in a 29-year old bodybuilder with a history of anabolic androgenic steroid abuse: a case report
Background
Continuous use of anabolic androgenic steroid in high-doses is associated with substantial health risks, including hepatocellular adenoma. Malignant transformation from hepatocellular adenoma to hepatocellular carcinoma after anabolic androgenic steroid abuse has been rarely reported. The morphological distinction of adenoma from well-differentiated hepatocellular carcinoma is challenging and requires elaborated imaging techniques and histology.
Case presentation
We report about a 29-year old male professional bodybuilder who presented with mid-epigastric pain at the emergency unit. Ultrasound showed a severe hepatomegaly with multiple lesions. Contrast-enhanced ultrasound revealed a heterogeneous pattern with signs of hepatocellular carcinoma. CT scan of the abdomen confirmed multiple hypervascular lesions and central areas of necrosis without contrast enhancement. Subsequent diagnostics included fine needle aspiration (FNA) of suspicious lesions and mini-laparoscopy to establish the diagnosis of a β-catenin and testosterone-receptor positive hepatocellular carcinoma embedded in multiple adenomas. The patient was subsequently treated by liver transplantation and remains tumor-free 27 month after surgery.
Conclusion
Hepatocellular carcinoma occurring in association with anabolic androgenic steroid abuse should sensitize physicians and especially professional bodybuilders for the harmful use of high doses of steroids.

Use of Doppler Ultrasonography to Predict the Outcome of Therapy for Renal-Artery Stenosis
The use of Doppler ultrasonography in patients with hypertension has led to an increase in the diagnosis of renal-artery stenosis. Patients with stenosis of more than 50 percent of the luminal diameter of a renal artery are usually treated with angioplasty (with or without stenting) or surgery to lower blood pressure or preserve renal function. However, in 20 to 40 percent of patients, treatment does not improve blood pressure or renal function. There is no reliable way to identify these patients prospectively.

School-related Subjective Well-being of Children with and without Special Educational Needs in Inclusive Classrooms
Given the importance of schools as socializing institutions, a key dimension of children’s subjective well-being (SWB) is their perception of school-related aspects. This study complements previous literature on various determinants of children’s SWB by focusing on students with special educational needs (SEN). Due to academic challenges, stigmatization, and exclusion, they are at risk of experiencing reduced SWB. With the implementation of inclusive education around the globe, students with SEN are more frequently enrolled in regular schools, and a question arises regarding how students with SEN assess their school-related SWB in inclusive settings. Drawing on longitudinal data from the National Educational Panel Study in Germany (NEPS) we systematically investigate the effect of the SEN status on various facets of school-related SWB measured in Grade 4 of primary school. Applying a propensity score matching approach, we contrast children with SEN status to children without SEN status who are comparable in a rich set of observed confounding variables. We find that at the end of primary school, students with SEN report being less
satisfied with life in general
, being less
satisfied with school
and their
friends
than their comparable counterpart without SEN. Moreover, they experience more
tiredness
and feelings of
loneliness
, and show lower levels of
learning enjoyment
and
task mastering
. The potential mechanisms leading to lower school-related SWB are discussed.

Editorial: Consequences of the Corona crisis for social inequalities in Germany
The possible consequences of the Corona crisis for social inequalities have received a lot of attention in public as well as scientific debates. On the one hand, concerns have been raised that the pandemic intensified pre-existing patterns of social inequality. On the other hand, the crisis has also been seen as an opportunity for social change and a renegotiation of social relationships. Complementing previous research that focused on the immediate consequences of the pandemic, this Special Issue is devoted to its longer-term effects. It unites six theory-guided empirical studies that use qualitative and quantitative longitudinal data to study changes in social inequality in the course of the pandemic in different life domains. Overall, the results do not show a universal trend of increased inequalities. While changes in different life domains occurred, such as better grading for students, intensified strong ties in families or increased social trust, there is only limited evidence of changes in social inequalities. In general, a complex picture of effects, consequences and concomitants of the pandemic appears.
