Linking masculinity to negative drinking consequences : the mediating roles of heavy episodic drinking and alcohol expectancies

This study extends previous research on masculinity and negative drinking consequences among young men by considering mediating effects of heavy episodic drinking (HED) and alcohol expectancies. We hypothesized that masculinity would have a direct relationship with negative consequences from drinking as well as indirect relationships mediated by HED and alcohol expectancies of courage, risk, and aggression.

MicroRNAs: biogenesis, roles for carcinogenesis and as potential biomarkers for cancer diagnosis and prognosis

MicroRNAs (miRNAs) are short non-coding RNAs of 20-24 nucleotides that play important roles in carcinogenesis. Accordingly, miRNAs control numerous cancer-relevant biological events such as cell proliferation, cell cycle control, metabolism and apoptosis. In this review, we summarize the current knowledge and concepts concerning the biogenesis of miRNAs, miRNA roles in cancer and their potential as biomarkers for cancer diagnosis and prognosis including the regulation of key cancer-related pathways, such as cell cycle control and miRNA dysregulation. Moreover, microRNA molecules are already receiving the attention of world researchers as therapeutic targets and agents. Therefore, in-depth knowledge of microRNAs has the potential not only to identify their roles in cancer, but also to exploit them as potential biomarkers for cancer diagnosis and identify therapeutic targets for new drug discovery.

Uncovering multiple champion roles in implementing new-technology ventures

This article reports the findings of a field study of a new venture electronic network enterprise from a business-to-business perspective. Network theory and the literatures of process innovation management and strategic marketing are used to generate theory about how new venture electronic network enterprises are created, and the roles champions play in their creation. Network champion roles and their relationships with other network participants are not well understood. The case study reveals how (a) network champions have both direct and indirect involvement in creating and commercializing new venture electronic networks, (b) champions within the venture rather than network champions strategically encourage or discourage supplier and buyer firms in joining, and (c) the accumulated knowledge of all champions, rather than the network champion alone, enhances successful implemented strategies. The findings provide researchers with a theoretical understanding of the role of the network champion in creating new ventures. Network champions filling multiple roles appear necessary for the successful creation of new hightech ventures.

Roles of civil society in nation-building and post-conflict reconstruction in Iraq

 This thesis aims to provide a nuanced typology of post-2003-war Iraqi CSOs that reflect their functions, rather their manifestations, by analysing and examining their roles in socio-economic service provisions and active citizenship; the impact of their roles in nation-building; and the geographic field (rural or urban) of their activities.

Gender roles and the education gender gap in Turkey

Using nationally representative data on individual subjective views on gender roles, we examine the gender gap in educational achievement in Turkey and show that the cultural bias against the education of girls is a fundamental factor behind their low educational attainment in socially conservative societies. The 1997 education reform in Turkey extended compulsory schooling from 5 to 8 years. Using the reform as a natural experiment, we investigate the impact of the reform on the effects of mothers’ traditional views in determining children’s educational attainment. We find that the reform helped reduce school dropout rates across the country. Nevertheless, regardless of the mother’s view on gender roles, the reductions in school dropout rates were similar for boys and girls, failing to eliminate the gender gap against girls. Turkey is an excellent environment to study the effects of societal gender roles since it combines modernity with traditionalism and displays a wide spectrum of views on gender roles. It is also one of the few developing countries where a gender gap to the detriment of females still exists in educational achievement

Crystals in Antheraea assamensis silkworm cocoon: their removal, recovery and roles

Brick shaped mineral deposits or crystals are found in the shell of semi-domestic silk cocoon of Antheraea assamensis (A. assamensis). Effective removal and recovery of these crystals are important to understand their roles in the cocoon's protective function towards pupae. In this study, chemical and physical (ultrasonication) demineralisation methods were investigated for A. assamensis. It was found that the physical demineralisation method could effectively separate crystals without changing their shape and size and not effecting other components of the silk cocoon. The efficient recovery of the crystals, without any change in their chemical composition was confirmed based on FTIR, XRD and EDX techniques. Chemical demineralisation method was optimised and performed under milder conditions than reported in the past. It helped reeling of silk without much loss of strength or natural colour of silk fibre.

How servant leadership influences organizational citizenship behavior: the roles of LMX, empowerment, and proactive personality

© 2015 Springer Science+Business Media Dordrecht While the link between servant leadership and organizational citizenship behavior (OCB) has been established, the individual-level mechanisms underlying this relationship and its boundary conditions remain poorly understood. In this study, we investigate the salience of the mediating mechanisms of leader–member exchange (LMX) and psychological empowerment in explaining the process by which servant leaders elicit discretionary OCB among followers. We also examine the role of followers’ proactive personality in moderating the indirect effects of servant leadership on OCB through LMX and psychological empowerment. Analysis of survey data collected from 446 supervisor–subordinate dyads in a large Chinese state-owned enterprise suggests that while servant leadership is positively related to subordinate OCB through LMX, psychological empowerment does not explain any additional variance in OCB above that accounted for by LMX. Moderated mediation tests confirm the moderating effect of proactive personality through LMX. By providing a nuanced understanding of how and when servant leadership leads followers to go above and beyond their job role, our study assists organizations in deciding how to develop and utilize servant leaders in their organizations.

Explaining the intention-behaviour gap in gluten-free diet adherence: the moderating roles of habit and perceived behavioural control

Adherence to a strict gluten-free diet is the only treatment for coeliac disease. Nonetheless, many individuals with the disease struggle to achieve and maintain strict adherence. While the theory of planned behaviour is useful for predicting gluten-free diet adherence, an intention-behaviour gap remains. The aim of this study was to investigate the roles of habit and perceived behavioural control in moderating the intention-behaviour relationship in gluten-free diet adherence. A significant three-way interaction was found such that the association between intention and adherence was dependent on both perceived behavioural control and habit. Implications for both theory and intervention design are discussed.

Explaining psychological insulin resistance in adults with non-insulin-treated type 2 diabetes: the roles of diabetes distress and current medication concerns. Results from diabetes MILES-Australia.

AIMS: To investigate the contribution of general and diabetes-specific emotional wellbeing and beliefs about medicines in the prediction of insulin therapy appraisals in adults with non-insulin-treated type 2 diabetes. METHODS: The sample included Diabetes MILES-Australia cross-sectional survey participants whose primary diabetes treatment was oral hypoglycaemic agents (N=313; 49% women; mean±SD age: 57±9 years; diabetes duration: 7±6 years). They completed validated measures of beliefs about the 'harm' and 'overuse' of medications in general (BMQ General); 'concerns' about and 'necessity' of current diabetes medications (BMQ Specific); negative insulin therapy appraisals (ITAS); depression (PHQ-9); anxiety (GAD-7), and diabetes distress (DDS-17). Factors associated with ITAS Negative scores were examined using hierarchical multiple regressions. RESULTS: Twenty-two percent of the variance in ITAS Negative scores (52±10), was explained by: number of complications (β=-.15, p=.005), DDS-17 subscale 'emotional burden' (β=.23, p<.001), and 'concerns' about current diabetes treatment (β=.29, p<.001). General beliefs about medications and general emotional wellbeing did not contribute significantly to the model. CONCLUSIONS: Psychological insulin resistance may reflect broader distress about diabetes and concerns about its treatment but not general beliefs about medicines, depression or anxiety. Reducing diabetes distress and current treatment concerns may improve attitudes towards insulin as a potential therapeutic option.

Reasons and remedies for under-representation of women in medical leadership roles: a qualitative study from Australia

OBJECTIVE: To elicit medical leaders' views on reasons and remedies for the under-representation of women in medical leadership roles.

DESIGN: Qualitative study using semistructured interviews with medical practitioners who work in medical leadership roles. Interviews were transcribed verbatim and transcripts were analysed using thematic analysis.

SETTING: Public hospitals, private healthcare providers, professional colleges and associations and government organisations in Australia.

PARTICIPANTS: 30 medical practitioners who hold formal medical leadership roles.

RESULTS: Despite dramatic increases in the entry of women into medicine in Australia, there remains a gross under-representation of women in formal, high-level medical leadership positions. The male-dominated nature of medical leadership in Australia was widely recognised by interviewees. A small number of interviewees viewed gender disparities in leadership roles as a 'natural' result of women's childrearing responsibilities. However, most interviewees believed that preventable gender-related barriers were impeding women's ability to achieve and thrive in medical leadership roles. Interviewees identified a range of potential barriers across three broad domains-perceptions of capability, capacity and credibility. As a counter to these, interviewees pointed to a range of benefits of women adopting these roles, and proposed a range of interventions that would support more women entering formal medical leadership roles.

CONCLUSIONS: While women make up more than half of medical graduates in Australia today, significant barriers restrict their entry into formal medical leadership roles. These constraints have internalised, interpersonal and structural elements that can be addressed through a range of strategies for advancing the role of women in medical leadership. These findings have implications for individual medical practitioners and health services, as well as professional colleges and associations.

Transforming roles to support student development of academic literacies: a reflection on one team’s experience

Abstract: Social work is a discipline that attracts students from diverse academic backgrounds. Many are first in family to attend university, and come to university through alternative pathways such as vocational education. As a result, there are higher levels of attrition compared to other disciplines, especially in the first year. To address this, and in keeping with a commitment to provide accessible education, one school of social work undertook a project to embed academic literacies into the curriculum. This paper used Gibb’s reflective process to explore how this was experienced by team members. Data were collected via staff focus groups at two different points in time across the project and compared. The reflection unpacked a number of tensions experienced by team members, including concerns about potential loss of resources as a result of academics adopting new roles, and concerns about implementing what was seen as Westernised academic skills which may not fit with students’ ways of thinking and creating knowledge. Overfull curricula and constant change also appeared to be of concern. The reflection highlighted that to achieve effective and sustainable change, action was required at multiple levels.

Cognitive cultural intelligence and life satisfaction of migrant workers: the roles of career engagement and social injustice

This paper examines the mediating effect of career engagement on the relationship between cognitive cultural intelligence (CQ) and life satisfaction among international migrant workers in Australia. It also examines the moderating effect of perceived social injustice on the cognitive CQ–career engagement relationship, as well as on the indirect cognitive CQ–life satisfaction relationship via career engagement. Using survey data from four hundred and sixty-two migrant workers in Australia, it was found that cognitive CQ was positively related to life satisfaction and that career engagement mediated this relationship. Social injustice moderated the impact of cognitive CQ on career engagement such that the impact was stronger among those perceiving a higher rather than a lower level of social injustice. Furthermore, the indirect effect of cognitive CQ on life satisfaction via career engagement was also stronger for those perceiving higher social injustice. These findings provide new insights regarding the antecedents of life satisfaction as well as reveal a vocationally relevant mechanism underlying the relationship between cognitive CQ and life satisfaction. The results inform potential practical strategies to enhance the career progression and life satisfaction of international migrant workers.
