Research has shown that gender references in job advertisements play an important role for gender (in)equality in personnel selection. In advertisements gender is referred to in different ways, for instance, by using grammatically masculine and feminine human nouns (e.g., German Mechaniker/Mechanikerin 'mechanic, masc./fem.'), by mentioning typically feminine or typically masculine traits (e.g., kind and friendly versus determined and independent) as well as by showing pictures of women and men. The present study addresses the questions which forms of gender references occur in job advertisements, how these forms are distributed across different lines of business and across different countries. We collected job advertisements published online in four countries with different rankings of gender equality (i.e., Switzerland, Austria, Poland, and Czech Republic; World Economic Forum, 2011). We randomly selected 100 advertisements per country from four lines of business that are characterized by different proportions of female and male employees: (1) steels/metals, (2) science, (3) restaurants/food services, and (4) health care. The advertisements were analyzed with regard to the linguistic form of the job title and of the remaining text as well as reference to gender-typical traits. We also examined indicators of job status and other information (e.g., equal opportunity policies) which might be related to the use of gender references in job advertisements. The results show that, in general, gender-fair language occurs much more often in job ads from Switzerland and Austria than in those from Poland and the Czech Republic, where job titles are mostly masculine. While exclusive use of feminine forms are almost never used in Switzerland and Austria, they are more frequently used in Poland and Czech Republic. In general, gender-fair forms are more common when there are many women in a line of business, whereas more masculine forms are used where the proportion of women is low. In Switzerland and Austria, masculine forms are mostly combined with the supplement m/f to indicate that both women and men are addressed. The present data provide a sound basis for future studies on gender references in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality.

Research has shown that gender references in job advertisements play an important role for gender (in)equality in personnel selection. The use of pair forms (masculine and feminine form) in German-language job advertisements, for example, was found to reduce the lack of fit between women and leadership roles (Horvath & Sczesny, 2013). Therefore the present study addresses the question which forms of gender reference are used in job advertisements, how these forms are distributed in different countries and how language use is related to gender typicality and status of the job. We collected job advertisements published online in four countries with different rankings of gender equality (i.e., Switzerland, Austria, Poland, and Czech Republic; World Economic Forum, 2011). We randomly selected 100 advertisements per country from four branches that are characterized by different proportions of female and male employees: steels/metals, science, restaurants/food services, and health care. The advertisements were analyzed with regard to gender references as well as different indicators of job status. The results show that, in general, men and women are addressed more equally in Swiss and Austrian job advertisements compared to Polish and Czech job advertisements. The results also show that women and men are addressed more equally in branches where the proportion of women is high than where the proportion of women is low. We thus can conclude that the use of gender references is associated with the degree of gender equality achieved in a country and with the gender typicality of a profession.

Arguably, job satisfaction is one of the most important variables with regard to work. When explaining job satisfaction, research usually focuses on predictor variables in terms of levels but neglects growth rates. Therefore it remains unclear how potential predictors evolve over time and how their development affects job satisfaction. Using multivariate latent growth modeling in a study with 1145 young workers over five years, we analyzed how well job satisfaction is predicted a) by levels of situational (i.e., job control) and dispositional (i.e., Core Self-Evaluations (CSE)) factors and b) by growth per year of these predictors. Results showed both intercepts and slopes to be related to each other, suggesting a joint growth of job control and CSE during early careers. Job satisfaction after five years was best predicted by the slopes of job control (β = .31, p < .001) and CSE (β = .34, p < .01). These findings provide further longitudinal evidence for the role of situational as well as dispositional factors for predicting job satisfaction. In addition, growth rates per year were better predictors than initial levels. Furthermore, a lack of change in job control or CSE went along with a drop in job satisfaction, implying that young workers need to perceive things to be improving in order to increase, or at least maintain, their level of job satisfaction. In terms of theory, the relative importance of levels versus changes deserves more attention. In terms of practical implications, our results suggest a double emphasis on job design (i.e., granting sufficient, and increasing, control) and on personal development (e.g., through training) so that people experience a match between both. Finally, negative associations between initial levels and growth rates suggest that people are quite successful in achieving a reasonable fit between their job characteristics and their needs and goals.

The aim of this project is to investigate the use of gender-fair language from a cross-linguistic perspective. Specifically, we are interested in whether the use of gender-fair language correlates with socio-economic rankings of gender equality and with structural features of a language. We decided to analyze online job advertisements, as they reflect common language use and can easily be compared across languages. Moreover, formulations in job advertisements have been shown to impact personnel selection via the way target groups are addressed and referred to. In the present study we examined to what extent job advertisements are formulated in a gender-fair way and how this correlates with factors such as language, culture as well as status and gender-typicality of the job advertised. The data consisted of job advertisements published online in four European countries which occupy different positions in socio-economic rankings of gender equality (World Economic Forum, 2011): Switzerland (10), Austria (rank 34), Poland (42), and Czech Republic (75). We randomly selected 100 job advertisements from four lines of business characterized by different proportions of female employees – steels/metals, science, restaurants/food services, and health care. The advertisements were analyzed with regard to the linguistic form of the job title and the remaining text; we also noted indicators of job status, reference to gender-typical traits, pictures of women/men and other information which might be relevant to the use of gender-fair language (e.g., equal opportunity policies). A first analysis of the data indicates that the phrasing of job titles is closely related to the gender-typicality of a profession. While mainly gender-fair forms are used in healthcare, masculine forms are used more often in the domain of steels and metals. Feminine forms only, however, are almost never used. Cultural differences as well as correlations with associated variables will be discussed.

Purpose Gender fair language use in job advertisements has been shown to impact the outcome of personnel selections. It is thus important to assess, to what extent gender fair language is used in job advertisements and with which factors it is associated, e.g., language, culture, status, and gender typicality of profession. Design/Methodology In the present research we investigated gender fair language use in job advertisements published online in four European countries with different socio-economic rankings of gender equality (World Economic Forum, 2011), namely Austria (rank 34), Czech Republic (75), Poland (42), and Switzerland (10). From four lines of business with different percentages of female employees – steels/metals, science, restaurants/food services, and health care –we randomly selected 100 job advertisements, summing up to 1600 job advertisements in total. Results A first analysis of the Swiss data indicates that the phrasing of job advertisements is closely related to a profession’s gender typicality (e.g., merely masculine forms are used in steels and metals, gender-fair forms in healthcare). Feminine forms however are almost never used. Cross-cultural comparisons will be presented. Limitations We analyzed job advertisements of four specific lines of business in four European countries. To what extend results can be generalized remains an open question. Research/Practical Implications The present data provide a sound basis for future studies on gender fair language use in job advertisements. Furthermore it sheds a light on how companies comply with national guidelines of gender equality. Originality/Value This is the first time that gender fair language use in job advertisements is investigated (a) across different countries and languages and (b) considering status and gender typicality of professions.

Metabolomics as one of the most rapidly growing technologies in the "-omics" field denotes the comprehensive analysis of low molecular-weight compounds and their pathways. Cancer-specific alterations of the metabolome can be detected by high-throughput mass-spectrometric metabolite profiling and serve as a considerable source of new markers for the early differentiation of malignant diseases as well as their distinction from benign states. However, a comprehensive framework for the statistical evaluation of marker panels in a multi-class setting has not yet been established. We collected serum samples of 40 pancreatic carcinoma patients, 40 controls, and 23 pancreatitis patients according to standard protocols and generated amino acid profiles by routine mass-spectrometry. In an intrinsic three-class bioinformatic approach we compared these profiles, evaluated their selectivity and computed multi-marker panels combined with the conventional tumor marker CA 19-9. Additionally, we tested for non-inferiority and superiority to determine the diagnostic surplus value of our multi-metabolite marker panels. Compared to CA 19-9 alone, the combined amino acid-based metabolite panel had a superior selectivity for the discrimination of healthy controls, pancreatitis, and pancreatic carcinoma patients [Formula: see text] We combined highly standardized samples, a three-class study design, a high-throughput mass-spectrometric technique, and a comprehensive bioinformatic framework to identify metabolite panels selective for all three groups in a single approach. Our results suggest that metabolomic profiling necessitates appropriate evaluation strategies and-despite all its current limitations-can deliver marker panels with high selectivity even in multi-class settings.

With more experience in the labor market, some job characteristics increase, some decrease. For example, among young employees who just entered the labor market, job control may initially be low but increase with more routine and experience. Job control is a job resource that is valued in itself and is positively associated with job satisfaction; but job control also helps dealing with stressors at work. There is little research on correlated changes, but the existing evidence suggests a joint development over time. However, even less is known about the relevance of such changes for employees. Usually, research tends to use mean levels to predict mean levels in outcomes but development in job control and stressors may be as relevant for job satisfaction as having a certain level in those job characteristics. Job satisfaction typically is regarded as a positive attitude towards one’s work. What has received less attention is that some employees may lower their expectations if their job situation does not reflect their needs, resulting in a resigned attitude towards one’s job. The present study investigates the development of job control and task-related stressors over ten years and tests the predictive value of changes in job control and task-related stressors for resigned attitude towards one’s job. We used data from a Swiss panel study (N=356) ranging over ten years. Job control, task-related stressors (an index consisting of time pressure, concentration demands, performance constraints, interruptions, and uncertainty about tasks), and resigned attitude towards one’s job were assessed in 1998, 1999, 2001, and 2008. Latent growth modeling revealed that growth rates of job control and task-related stressors were not correlated with one another. We predicted resigned attitude towards one’s job in 2008 a) by initial levels, and b) by changes in job control and stressors, controlling for resigned attitude in 1998. There was some prediction by initial levels (job control: β = -.15, p < .05; task-related stressors: β = .12, p = .06). However, as expected, changes in control and stressors predicted resigned attitude much better, with β = -.37, p < .001, for changes in job control, and β = .31, p < .001, for changes in task-related stressors. Our data confirm the importance of having low levels of task-related stressors and higher levels of job control for job attitudes. However, development in these job characteristics seems even more important than initial levels.

Motivation plays a key role in successful entry into working life. Based on a cross-sectional and a one-year longitudinal study, we used a person-centered approach to explore work-related motivation (i.e., autonomous goals, positive affect, and occupational self-efficacy) among 577 students in 8th grade (Study 1) and 949 adolescents in vocational training (Study 2). Based on latent profile analysis, in both studies we identified four groups that were characterized by different levels of overall motivation and one group characterized by low positive affect and mean levels in autonomous goals and self-efficacy. Profiles characterized by high levels of motivation showed the highest levels of positive work expectations and goal engagement and the lowest levels of negative work expectations in Study 1 and the highest levels of person-job fit, work engagement, and job satisfaction in Study 2. Moreover, latent difference score analysis showed that motivational profiles predicted changes in person-job fit and work engagement across one year but not in job satisfaction. The results imply that career counselors should be aware of characteristic motivational patterns of clients that may require specific counseling approaches.

Purpose When applying for leadership positions or acting as leaders, women are still perceived with a ‘lack of fit’, thus hired less likely and evaluated less favorably than their male counterparts. In many languages, different language forms can be used to refer to both women and men: masculine forms (e.g., CEO in German: ‘Geschäftsführer’) and alternative forms (e.g., feminine‐masculine word pairs, CEO in German ‘Geschäftsführerin/Geschäftsführer’). We assumed that the use of masculine forms endorses the ‘lack of fit’ for women in leadership, whereas alternative forms reduce it. Design/Methodology Two studies tested the hypotheses by manipulating language forms (masculine forms vs. alternative forms) and gender of the target to hire/evaluate (female vs. male). Results The results indicated as predicted that masculine forms lead to the ‘lack of fit’ for women in the leadership context, whereas alternative forms reduce it. Women were less likely to be employed for leadership positions (Study 1) and evaluated less favorably as leaders (Study 2) than their male counterparts with masculine forms. However, with alternative forms no differences in employment decisions and evaluations of women and men were found. Limitations These two studies were conducted with student‐samples. Further research is needed to replicate effects with relevant samples as HRmanagers and to investigate underlying mechanisms. Research/Practical Implications Organizations may use alternative forms instead of masculine forms in job advertisements for leadership positions to overcome barriers for women in leadership. Originality/Value These are the first studies in testing the effects of language forms in the leader selection and evaluation.

Indirect plant-mediated interactions between herbivores are important drivers of community composition in terrestrial ecosystems. Among the most striking examples are the strong indirect interactions between spatially separated leaf- and root-feeding insects sharing a host plant. Although leaf feeders generally reduce the performance of root herbivores, little is known about the underlying systemic changes in root physiology and the associated behavioral responses of the root feeders. We investigated the consequences of maize (Zea mays) leaf infestation by Spodoptera littoralis caterpillars for the root-feeding larvae of the beetle Diabrotica virgifera virgifera, a major pest of maize. D. virgifera strongly avoided leaf-infested plants by recognizing systemic changes in soluble root components. The avoidance response occurred within 12 h and was induced by real and mimicked herbivory, but not wounding alone. Roots of leaf-infested plants showed altered patterns in soluble free and soluble conjugated phenolic acids. Biochemical inhibition and genetic manipulation of phenolic acid biosynthesis led to a complete disappearance of the avoidance response of D. virgifera. Furthermore, bioactivity-guided fractionation revealed a direct link between the avoidance response of D. virgifera and changes in soluble conjugated phenolic acids in the roots of leaf-attacked plants. Our study provides a physiological mechanism for a behavioral pattern that explains the negative effect of leaf attack on a root-feeding insect. Furthermore, it opens up the possibility to control D. virgifera in the field by genetically mimicking leaf herbivore-induced changes in root phenylpropanoid patterns.
