Combining Bottom-up and Top-down Generation of Interactive Knowledge Maps for Enterprise Search

Our research project develops an intranet search engine with concept- browsing functionality, where the user is able to navigate the conceptual level in an interactive, automatically generated knowledge map. This knowledge map visualizes tacit, implicit knowledge, extracted from the intranet, as a network of semantic concepts. Inductive and deductive methods are combined; a text ana- lytics engine extracts knowledge structures from data inductively, and the en- terprise ontology provides a backbone structure to the process deductively. In addition to performing conventional keyword search, the user can browse the semantic network of concepts and associations to find documents and data rec- ords. Also, the user can expand and edit the knowledge network directly. As a vision, we propose a knowledge-management system that provides concept- browsing, based on a knowledge warehouse layer on top of a heterogeneous knowledge base with various systems interfaces. Such a concept browser will empower knowledge workers to interact with knowledge structures.

Applying Fuzzy Ontologies to Implement the Social Semantic Web

Because the knowledge in the World Wide Web is continuously expanding, Web Knowledge Aggregation, Representation and Reasoning (abbreviated as KR) is becoming increasingly important. This article demonstrates how fuzzy ontologies can be used in KR to improve the interactions between humans and computers. The gap between the Social and Semantic Web can be reduced, and a Social Semantic Web may become possible. As an illustrative example, we demonstrate how fuzzy logic and KR can enhance technologies for cognitive cities. The underlying notion of these technologies is based on connectivism, which can be improved by incorporating the results of digital humanities research.

The positive effects of protean career attitude for self-initiated expatriates: Cultural adjustment as a mediator

Purpose – The authors sought to explain why and how protean career attitude might influence self‐initiated expatriates' (SIEs) experiences positively. A mediation model of cultural adjustment was proposed and empirically evaluated. Design/methodology/approach – Data from 132 SIEs in Germany containing measures of protean career attitude, cultural adjustment, career satisfaction, life satisfaction, and intention to stay in the host country were analysed using path analysis with a bootstrap method. Findings – Empirical results provide support for the authors' proposed model: the positive relations between protean career attitude and the three expatriation outcomes (career satisfaction, life satisfaction and intention to stay in the host country) were mediated by positive cross‐cultural adjustment of SIEs. Research limitations/implications – All data were cross‐sectional from a single source. The sample size was small and included a large portion of Chinese participants. The study should be replicated with samples in other destination countries, and longitudinal research is suggested. Practical implications – By fostering both a protean career attitude in skilled SIE employees and their cultural adjustment, corporations and receiving countries could be able to retain this international workforce better in times of talent shortage. Originality/value – This study contributes to the scarce research on the conceptual relatedness of protean career attitude and SIEs, as well as to acknowledging the cultural diversity of the SIE population.

Gender-fair language use in online job advertisements - relations to job status and gender equality

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.

Vocational Interests and Career Goals: Development and Relations to Personality and Middle Adolescence

Cross-sectional research implies a close relation of vocation interests, goals, and traits, yet little is known about their reciprocal development over time. This longitudinal study examined development of Things/People (T/P) and Data/Ideas (D/I) vocational interests and career goals in relation to Big Five personality traits among 292 Swiss adolescents with a cross-lagged panel design with two measurement points over 1 year from seventh to eighth grade. Interests and goals were significantly related within time and showed significant interactions across time. Traits related significantly and equally to interests and goals within time and predicted their development across time except for T/P goals. Goals and interests possessed incremental validity above traits in affecting each other. Implications include the need to account for dynamic processes in the development of goals and interests and their systematic relation to traits in theory and practice.

Career adaptivity, adaptability, and adapting: A conceptual and empirical investigation

The literature on career adaptation is vast and based on a range of different measurement approaches. The present paper aims to explore how different operationalizations of career adaptability in terms of concern, control, curiosity, and confidence are related from a conceptual and empirical standpoint. Based on a cross-sectional analysis with 1260 German university students, we established that the adaptability resources of concern, control, curiosity, and confidence are significantly related to, but empirically distinct from, measures representing adapting in terms of career planning, career decision-making difficulties, career exploration, and occupational self-efficacy. In a follow-up survey six months later, we found that the career adaptability dimensions partially mediated the effects of adaptivity (i.e., core self-evaluations and proactivity) on planning, decision-making difficulties, exploration, and self-efficacy. Interestingly, in both analyses, there was no clear match between adaptability resources and theoretically corresponding aspects of career adapting in terms of behaviors, beliefs, and barriers. The results suggest that psychological career resources in terms of concern, control, curiosity, and confidence partially mediate the effects of more context-general, trait-like adaptivity on different career-specific behavioral forms of adapting.

Conceptual design and simulation of a water Cherenkov muon veto for the XENON1T experiment

XENON is a dark matter direct detection project, consisting of a time projection chamber (TPC) filled with liquid xenon as detection medium. The construction of the next generation detector, XENON1T, is presently taking place at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy. It aims at a sensitivity to spin-independent cross sections of 2 10-47 c 2 for WIMP masses around 50 GeV2, which requires a background reduction by two orders of magnitude compared to XENON100, the current generation detector. An active system that is able to tag muons and muon-induced backgrounds is critical for this goal. A water Cherenkov detector of ~ 10 m height and diameter has been therefore developed, equipped with 8 inch photomultipliers and cladded by a reflective foil. We present the design and optimization study for this detector, which has been carried out with a series of Monte Carlo simulations. The muon veto will reach very high detection efficiencies for muons (>99.5%) and showers of secondary particles from muon interactions in the rock (>70%). Similar efficiencies will be obtained for XENONnT, the upgrade of XENON1T, which will later improve the WIMP sensitivity by another order of magnitude. With the Cherenkov water shield studied here, the background from muon-induced neutrons in XENON1T is negligible.

A longitudinal cross-country study of entrepreneurial orientation

As recent research documents, there has been an impressive effort of studying the entrepreneurial orientation construct and its nomological role. However, most research has been very context specific and based on the analyses of cross-sectional information. We study causal performance effects from entrepreneurial orientation and its key dimensions in two economic contexts–developed and emerging markets. Gathering data on a sample of 94 firms in developed market context and 108 in emerging market context at two time-points we explore our hypotheses. The results suggest that in a developed economy entrepreneurial orientation has a positive impact on firm performance, whereas in the emerging market context this effect is negative. Furthermore, we assess the contribution of each dimension to the aggregate construct and reveal the importance of risk-taking in both contexts. Finally, we highlight the role of environmental dynamism and explain its varying effect

Institutions for sustainable governance of forests: Equity, robustness and cross-level interactions in Mawlyngbna, Meghalaya, India

This study adopts Ostrom’s Social-Ecological Systems (SES) framework in empirical fieldwork to explain how local forestry institutions affect forest ecosystems and social equity in the community of Mawlyngbna in North-East India. Data was collected through 26 semi-structured interviews, participatory timeline development, policy documents, direct observation, periodicals, transect walks, and a concurrent forest-ecological study in the village. Results show that Mawlyngbna's forests provide important sources of livelihood benefits for the villagers. However, ecological disturbance and diversity varies among the different forest ownership types and forest-based livelihood benefits are inequitably distributed. Based on a bounded rationality approach, our analysis proposes a set of causal mechanisms that trace these observed social-ecological outcomes to the attributes of the resource system, resource units, actors and governance system. We analyse opportunities and constraints of interactions between the village, regional, and state levels. We discuss how Ostrom’s design principles for community-based resource governance inform the explanation of robustness but have a blind spot in explaining social equity. We report experiences made using the SES framework in empirical fieldwork. We conclude that mapping cross-level interactions in the SES framework needs conceptual refinement and that explaining social equity of forest governance needs theoretical advances.

Adolescents’ willingness for intergenerational support: Relations to maternal expectations and mothers’ life satisfaction in 14 cultures

How is adolescents’ willingness for intergenerational support affected by parents’ expectations and parenting behavior? Does youths’ willingness for intergenerational support in turn affect parents’ well-being? The current study addresses these questions from a cross-cultural perspective, using data from connected samples of mother-adolescent dyads (N = 4162) from 14 diverse cultural contexts as part of the “Value of Children and Intergenerational Relations Study” (Trommsdorff & Nauck, 2005). The results are based on mixed model analyses (with culture as a random factor). Associations were investigated between family norms (expectations of support by adult children), parenting goals (obedience, independence) and parenting behavior (acceptance, control) reported by mothers and adolescents’ reports on willingness to support (help in household tasks, willingness to tolerate burdens in order to help their parents in case of accident, emotional support given to mothers and fathers). Across cultures, maternal expectations of adult children were positively related to adolescents’ reported household help and their current emotional support to mothers and fathers. Obedience, and control were positively related to the amount of adolescent help in the household, while independence and acceptance were related to a higher willingness to tolerate burdens as well as to higher emotional support given to the mother. Regarding associations between adolescents’ actual and intended intergenerational support with mothers’ life satisfaction, adolescents’ willingness to tolerate burdens was related to a higher maternal life satisfaction while adolescents’ reported household help was not. Adolescents’ current emotional support to fathers (but not to mothers) was also related to higher maternal life satisfaction. While most of the effects were stable across cultures (no significant random slope variance across cultural groups), some effects did significantly vary across cultures. Traditional-vs.-secular values as culture-level characteristics will be discussed as explanation for these culture-specific relations among mothers’ expectations, adolescents’ intergenerational support, and mothers’ life satisfaction.

Perceived gender relations and sexual relations among undergraduate female students in the Mekong Delta of Vietnam

Background. Literature worldwide has documented associations between gender-based relationship inequity, sexual communication self-efficacy, and actual use of condoms and contraceptives among young women. However studies that have rigorously tested these associations in southern Vietnam are extremely rare. This study aimed to examine these associations and other current sexual practices among undergraduate female students in the Mekong Delta. Method. A qualitative study was conducted to examine the operationalization of the Theory of Gender and Power and to obtain salient and culture-relevant dimensions of perceived gender relations in the Mekong Delta of Vietnam. Sixty-four undergraduate female students from two universities participated in eight group discussions focusing on their viewpoints regarding national and local gender equity issues. A subsequent cross-sectional survey consisting of 1181 third-year female students from Can Tho University and An Giang University was conducted. Latent variable modeling and logistic regression were employed to examine the hypothesized associations. Results. Dimensions of perceived gender relations were attributable to theoretical structures of labor, power, and cathexis. Perceptions about gender inequities were comparable to findings from several reports, in which women were still viewed as inferior and subordinate to men. Among students who had ever had a boyfriend(s) (72.4%), 44.8% indicated that their boyfriend had ever asked for sex, 13% had ever had penile-vaginal sex, and 10.3% had ever had oral sex. For those who had ever had penile-vaginal sex, 33% did not use any contraceptive method at first sex. The greater a student’s perception that women were subordinate to men, the lower her self-efficacy for sexual communication and the lower her actual frequencies of asking for contraceptive or condom use. Sexual communication self-efficacy was marginally associated with actual contraceptive use (p=.039) and condom use (p=.092) at first sex. Conclusion. Sexual health promotion strategies should address the influence of perceived unequal gender relations on young women’s sexual communication self-efficacy and the subsequent impact on actual contraceptive and condom use.^
