Getting What (Employers Think) You’re Worth – Evidence on the Gender Gap in Entry Wages among University Graduates

Since the early 1970s, wage differentials between men and women have attracted the research interest of labor economists. However, up to now empirical evidence on gender differentials of labor market entrants and the determinants of their starting wages is scarce. To fi ll this gap, we make use of a unique dataset on graduates in economics from a large representative German university, to investigate whether – even for such a homogeneous group of labor market entrants – a gender gap in earnings exists. Concentrating on a highly homogeneous sample limits the problem of unobserved heterogeneity, which results in an overestimation of the unexplained component of standard decompositions analyses. The results reveal that women’s entry wages are significant lower than those of their male counterparts. Blinder-Oaxaca decompositions suggest that the major part of this gap remains unexplained by gender differences in observable characteristics.Entry wage; gender wage gap; decomposition; university graduates

Methods for Evaluating Educational Programs – Does Writing Center Participation Affect Student Achievement?

This paper evaluates the eff ectiveness of the introduction of a Writing Center at a university. The center has the purpose to provide subject-specifi c courses that aim to improve students‘ abilities of scientifi c writing. In order to deal with presumed selfperceptional biases of students in feedback surveys, we use diff erent quantitative evaluation methods and compare the results to corresponding qualitative student surveys. Based on this evaluation, we present and discuss the validity of the approaches to evaluate educational programs. Although almost all students reported the writing courses to be helpful, we fi nd no signifi cant eff ect of course participation on students‘ grades. We attribute the diff erence in the results between quantitative methods and qualitative surveys to the inappropriateness of student course evaluations for assessing the eff ectiveness of educational measures.Performance evaluation; educational programs; student evaluation; empirical methods

The Role of Source- and Host-Country Characteristics in Female Immigrant Labor Supply

Using data from the European Social Survey 2002-2011 covering immigrants in 26 European countries, this paper analyzes the impact of source- and host-country characteristics on female immigrant labor supply. We find that immigrant women’s labor supply in their host country is positively associated with the labor force participation rate in their source country, which serves as a proxy for the country’s preferences and beliefs regarding women’s roles. The effect of this cultural proxy on the labor supply of immigrant women is robust to controlling for spousal, parental, and a variety of source-country characteristics. This result suggests that the culture and norms of their source country play an important role for immigrant women’s labor supply. Moreover, we find evidence for a strong positive correlation between the host-country female labor force participation rate and female immigrant labor supply, suggesting that immigrant women assimilate to the work behavior of natives

The Role of Source- and Host-Country Characteristics in Female Immigrant Labor Supply

Using data from the European Social Survey (ESS) 2002-2011 covering immigrants in 26 European countries, this paper analyzes the impact of source- and host-country characteristics on female immigrant labor supply. We find that the labor supply of immigrant women in Europe is positively associated with the female-to-male labor force participation ratio in their source country, which serves as a proxy for the country's preferences and beliefs regarding women's roles. This suggests that the culture and norms of their source country play an important role for immigrant women's labor supply. We further find evidence for a strong positive correlation between the labor force participation ratio in the host country and female immigrant labor supply, suggesting that immigrant women assimilate to the work behavior of natives

Diet-induced weight loss alters hepatic glucocorticoid metabolism in type 2 diabetes mellitus

Context: Altered tissue-specific glucocorticoid metabolism has been described in uncomplicated obesity and type 2 diabetes. We hypothesized that weight loss induced by diet and exercise, which has previously been shown to reverse abnormal cortisol metabolism in uncomplicated obesity, also normalizes cortisol metabolism in patients with type 2 diabetes. Objective: Test the effects of a diet intervention with added exercise on glucocorticoid metabolism. Design: Two groups followed a Paleolithic diet (PD) for 12 weeks with added 180 min of structured aerobic and resistance exercise per week in one randomized group (PDEX). Setting: Umea University Hospital. Participants: Men and women with type 2 diabetes treated with lifestyle modification +/- metformin were included. Twenty-eight participants (PD, n = 15; PDEX, n = 13) completed measurements of glucocorticoid metabolism. Main outcome measures: Changes in glucocorticoid metabolite levels in 24-h urine samples, expression of HSD1181 mRNA in s.c. adipose tissue and conversion of orally administered cortisone to cortisol measured in plasma. Body composition and insulin sensitivity were measured using a hyperinsulinemic-euglycemic clamp, and liver fat was measured by magnetic resonance spectroscopy. Results: Both groups lost weight and improved insulin sensitivity. Conversion of orally taken cortisone to plasma cortisol and the ratio of 5 alpha-THF + 5 beta-THF/THE in urine increased in both groups. Conclusions: These interventions caused weight loss and improved insulin sensitivity with concomitant increases in the conversion of cortisone to cortisol, which is an estimate of hepatic HSD11B1 activity. This suggests that dysregulation of liver glucocorticoid metabolism in these patients is a consequence rather than a cause of metabolic dysfunction

A Comparison of Different Matrices for the Laboratory Diagnosis of the Epizootic American Foulbrood of Honey Bees

American Foulbrood (AFB) of honey bees caused by the spore-forming bacterium Paenibacillus larvae is a notifiable epizootic in most countries. Authorities often consider a rigorous eradication policy the only sustainable control measure. However, early diagnosis of infected but not yet diseased colonies opens up the possibility of ridding these colonies of P. larvae spores by the shook swarm method, thus preventing colony destruction by AFB or official control orders. Therefore, surveillance of bee colonies for P. larvae infection followed by appropriate sanitary measures is a very important intervention to control AFB. For the detection of P. larvae spores in infected colonies, samples of brood comb honey, adult bees, or hive debris are commonly used. We here present our results from a comparative study on the suitability of these matrices in reliably and correctly detecting P. larvae spores contained in these matrices. Based on the sensitivity and limit of detection of P. larvae spores in samples from hive debris, adult bees, and brood comb honey, we conclude that the latter two are equally well-suited for AFB surveillance programs. Hive debris samples should only be used when it is not possible to collect honey or adult bee samples from brood combs

Structural analysis of a genetically encoded fret biosensor by SAXS and MD simulations

Inspired by the modular architecture of natural signaling proteins, ligand binding proteins are equipped with two fluorescent proteins (FPs) in order to obtain Förster resonance energy transfer (FRET)-based biosensors. Here, we investigated a glucose sensor where the donor and acceptor FPs were attached to a glucose binding protein using a variety of different linker sequences. For three resulting sensor constructs the corresponding glucose induced conformational changes were measured by small angle X-ray scattering (SAXS) and compared to recently published single molecule FRET results (Höfig et al., ACS Sensors, 2018). For one construct which exhibits a high change in energy transfer and a large change of the radius of gyration upon ligand binding, we performed coarse-grained molecular dynamics simulations for the ligand-free and the ligand-bound state. Our analysis indicates that a carefully designed attachment of the donor FP is crucial for the proper transfer of the glucose induced conformational change of the glucose binding protein into a well pronounced FRET signal change as measured in this sensor construct. Since the other FP (acceptor) does not experience such a glucose induced alteration, it becomes apparent that only one of the FPs needs to have a well-adjusted attachment to the glucose binding protein
