The end of post-enlargement migration from Poland?
Authors: Grabowska Izabela , Czeranowska Olga , Wermińska-Wiśnicka Iga 
Published: March 2023

Abstract

Intro: The main aim of this article is to discuss a change in a post-enlargement migration picture of the European Union (EU) through analysing migrant selectivity from households remaining in an origin of Central and Eastern Europe (CEE), in Poland. We link the properties of selectivity to various socio-demographic and economic characteristics, which helps us sub-stratify the population of migrants with special focus on young adult migrants who dominated in the phenomenal post-accession migration flows from CEE for many years after the EU enlargement in May 2004, especially to the UK which was the key destination.
Method: Applying the concept of migrant selectivity requires datasets for general populations, such as the Labour Force Survey, in which both migrants and non-migrants can be identified.
Results: We established, contrary to our initial hypothesis about sustaining a positive post-enlargement selectivity of highly educated young adult migrants from Poland, that in a post-Brexit EU, men with intermediate education from rural areas select positively for going to work abroad, predominately to Germany, as it used to be in the pre-EU enlargement period of 2004.
Conclusion: With the help of the concept of migrant selectivity and with the data of Labour Force Survey which covers both migrant and non-migrant population, we were able to explain the phasing out of the social phenomenon of ‘post-enlargement migration’ as young adults with tertiary education are no more overrepresented in migration flows. It means that EU East-West migration normalises.

Abstract
Interannual variability and spatial synchrony of seed production, known as masting, have far-reaching ecological impacts including effects on forest regeneration and the population dynamics of seed consumers, predators, parasites, and diseases. Because the relative timing of management and conservation efforts in ecosystems dominated by masting species often determines their success, there is an urgent need to study masting mechanisms and develop anticipatory forecasting tools for seed production. In this study, we aim to establish seed production forecasting ("mast casts") as a new branch of the discipline. To assess the current state of the ability to model intrinsic and extrinsic drivers of masting, we evaluate the predictive capabilities of three models -foreMast, ΔT, and a sequential model based on the developmental steps of seed production - designed to predict seed production in trees using a pan-European dataset of Fagus sylvatica seed production as a case study. Our hindcasting analysis indicates that the models are moderately successful in recreating seed production dynamics, with the best-performing model achieving R2 = 0.66. The availability of high-quality data on prior seed production significantly improved the model's predictive power, with R2 = 0.78 in the sequential model, suggesting that effective seed production monitoring methods are crucial for creating reliable forecasting tools. In terms of extreme events, the models were better at predicting crop failures than bumper crops, likely because the factors preventing seed production are better understood than the processes leading to large reproductive events. To create widely applicable tools, we need models that can make forecasts over large areas with readily available data. We summarize the current challenges and provide a roadmap to help advance the discipline and encourage the further development of mast forecasting.
The CpG-dependent plant immune response to self-DNA triggers defence hormone signalling and improves fitness
Authors: Durán-Flores Dalia , Heil Martin 
Published: March 2023

Abstract

The accumulation of DNA in the cytoplasm or extracellular space is a signal of danger. Plants respond to this signal with a self/non-self-specific activation of early immune signalling events. Here, we asked whether this specificity translates to fitness-relevant resistance to natural enemies. We treated common bean (Phaseolus vulgaris) plants with self-DNA and with non-self-DNA from other plant species. Self-DNA treatment induced jasmonic acid and decreased feeding by a chewing herbivore (Spodoptera frugiperda), while self- and non-self-DNA induced salicylic acid and reduced the population densities of two fungal pathogens (Botrytis cinerea and Sclerotinia sclerotiorum) and of four bacterial pathogens (Enterobacter sp. strain FCB1, Pseudomonas syringae pv. phaseoli and pv. syringae, and Xanthomonas axonopodis pv. phaseoli). Strikingly, a single self-DNA-treatment increased seed production under field conditions in two seasons ca. 1.5-fold and 3.2-fold, while non-self-DNA had lower or no detectable effects. Stronger responses to self- than non-self-DNA seemingly contradict immunological theory. In mammalian immune cells, toll-like receptor 9 (TLR9) is activated by microbial DNA but also by mitochondrial (mt)DNA that is rich in unmethylated CpG motifs. Using bean suspension cells, we observed stronger immunogenic effects of genomic DNA than chloroplast DNA or mtDNA. Moreover, in vitro methylation or cleavage of CpG motifs reduced – without eliminating – the H2O2-inducing properties of DNA. We conclude that the plant immune response to DNA comprises a self/non-self-specific induction of major defence hormones that can be adaptive under natural enemy pressure and that unmethylated CpG motifs contribute to the immunogenic effects of DNA in plants.
The Effect of Stereotype Threat on the Interview Performance of Women
Authors: Shantz Amanda 
Published: March 2023

When women are in a situation whereby they are at risk of being judged by a negative stereotype, they underperform relative to men. This quandary is called stereotype threat. The present study examined whether stereotype threat affects the performance of men versus women in a simulated job interview. The stereotype that women are not suitable for managerial jobs was unobtrusively embedded in a job description presented to interviewees (n = 50) prior to the interview. The interviews were evaluated by four HR managers, two male and two female. The results showed that stereotype threat disadvantages females vis- -vis those in the control group, and it disadvantaged them relative to men in the stereotype threat condition. This occurred regardless of whether the HR manager was male or female
Occupational and Mental Health Consequences of Women's Experiences of Gender Discrimination and Negative Workplace Acts in the Legal Profession
Authors: Eansora Donna M. , Lafreniereb Kathryn D. 
Published: March 2023

Women have been entering the legal profession increasingly over the last three decades, yet continue to leave the profession at significantly greater rates than men. Previous research has documented the influence of workplace discrimination in influencing women's entry and retention in the legal profession, but less research attention has been directed toward the occupational and mental health consequences for these women. The present study examined whether negative acts in the workplace, gender discrimination, and work-life conflict were associated with negative occupational and mental health consequences for women lawyers. Questionnaires containing measures of negative acts in the workplace, gendered elements of the work environment, work-family conflict, job satisfaction, burnout, and mental health symptoms were mailed to a stratified random sample of Canadian women lawyers, resulting in a sample of 277 women lawyers from Alberta, Ontario, New Brunswick, and Nova Scotia. Findings supported our hypothesis that negative workplace experiences, including gender discrimination, would predict lower levels of job satisfaction and greater levels of burnout in women lawyers. In terms of mental health outcomes, work-life conflict emerged as the strongest predictor of perceived stress and anxiety, while negative workplace acts significantly predicted depression. The findings of this study highlight the importance of addressing negative acts and gender discrimination in the legal profession in order to increase women's job satisfaction and to safeguard their health and well-being.

This paper examines the role of mentoring among African American accountants to contribute to our knowledge in using mentoring as a potential tool to increase diversity in the accounting profession. First, we test whether African American women have lower number of beneficial mentors than African American men to see whether they both have enough access to beneficial mentors. We then compare the supports received and the perceived benefits from mentoring between African American women and men. We test the impact of type of mentoring (formal, informal, or both) on current job positions to see which type of mentoring is more beneficial. We also test the impact of the quantity of beneficial mentors on current job positions to see whether quantity matters. In general, we find that African American women are less likely to have beneficial mentors than African American men. However, our results suggest that African American women perceived similar or better supports and perceived similar benefits from their mentors. Lastly, we find that having informal mentors and having a greater number of beneficial mentors have positive impact in the current job positions.

Published: March 2023

This research aims to (1) evaluate the application of the teaching factory (Tefa) in the field of machining expertise in Vocational High Schools (VHSs) and (2) identify the obstacles to the implementation of Tefa. The research uses the CIPP (Content, Input, Process, and Product) evaluation method. This research was carried out in four vocational schools on the competence of machining expertise with the criteria of having implemented Tefa for more than five years and as a pioneer in implementing Tefa. The four schools are Vocational High School (VHS) Mikael Surakarta, State Vocational High School (SVHS) 1 Magelang, SMK Warga Surakarta, and SMK Karya Teknika Colomadu Karanganyar. The research respondents are principals, vice principals, heads of competency skills, and managers of Tefa. The data collection was through interviews, observation, and document scrutiny. The instruments used are an interview guide, observation sheet, and document analysis guide. The qualitative data analysis used qualitative data processing software. The results are as follows. (1) The application of Tefa in VHSs based on the evaluation is the context component 98%, the input component 89.25%, the process component 87%, and the product component 82.5 %. The percentage of evaluating the implementation of Tefa as a whole for the CIPP component is 89.2%, or very good; and (2) The obstacles faced in implementing Tefa in vocational high schools include rules for product sales, rules for working hours for public teachers, setting practicum schedules, working hours that were not flexible, rapid technological changes, understanding of block schedules, and lack of human resource competence. The results of this study imply that schools that implement Tefa are expected to be well-managed because it impacts the progress of VHS processes and products.
