A Comparison of Bayes Factors for Separated Models: Some Simulation Results

Some alternative Bayes Factors: Intrinsic, Posterior, and Fractional have been proposed to overcome the difficulties presented when prior information is weak and improper prior are used. Additional difficulties also appear when the models are separated or non nested. This article presents both simulation results and some illustrative examples analysis comparing these alternative Bayes factors to discriminate among the Lognormal, the Weibull, the Gamma, and the Exponential distributions. Simulation results are obtained for different sample sizes generated from the distributions. Results from simulations indicates that these alternative Bayes factors are useful for comparing non nested models. The simulations also show some similar behavior and that when both models are true they choose the simplest model. Some illustrative example are also presented.     

Comparing ‘deep’ insider knowledge: developing analytical strategies for cross-national qualitative studies

ABSTRACT

One overarching question in scholarly methodological discussions on qualitative comparative approaches concerns how it is possible to compare and generalise deep insider knowledge across (nationally) specific contexts. The aim of this article is to propose a research strategy that both facilitates the comparison and theorisation of such knowledge across nations and limits the risks of reproducing naturalised national ‘truths’. The strategy is developed within a feminist, cross-national, qualitative comparative analysis of how European countries addressed military deaths in connection with the ISAF mission in Afghanistan. The article underlines the importance of collective analytical work and of strategies that allow continuous movement between insider and outsider positions throughout the research process. A number of analytical strategies are presented: collective project design, alternating between analytical closeness and distance, and de-familiarising writing practices.     

Age group differences in political activism in Malaysia

ABSTRACT

There is a dearth of studies on age-related patterns of political activism in Malaysia, specifically on young people’s patterns of political participation relative to their elders, and in relation to the rich literature that has developed in Western democracies. By analysing survey data from Wave 6 (2010–2014) of the World Values Surveys (WVS), this study aims to investigate the differences in political engagement between younger and older people in Malaysia, including new repertoires outside the mainstream politics, by addressing the question of whether young Malaysians are more active in political activities compared to older groups. The findings conform to the expected patterns in the literature that young people are less likely to participate in conventional political activities than their respective elders. However, we find no significant differences for unconventional political participation. The study further shows that demographic indicators such as the levels of education, gender and ethnic group belonging do not appear to be linked to the age gap between youth and their elders in political activism. As such, the study provides evidence that young people in Malaysia are less likely to be politically active than their elders and that this is not clearly attributable to the socio-demographic factors analysed.     

Working precarious careers trajectories: tracing neoliberal discourses in younger workers’ narratives

ABSTRACT

The aim of this article is to explore how, in the context of the post Global Financial Crisis (GFC), some Italian younger workers in a specific geographical region in Italy recount their work trajectories. Drawing on narrative interviews with ten participants (aged between 24 and 30) as part of a research project carried out in the Autonomous region of Aosta Valley in Italy, the article traces discourses closely associated with neoliberalism – the discourses of the entrepreneurial self, employability and self-responsibilisation – through which subjects’ work experiences take shape. Moreover, the analysis highlights how locality, one’s personal relation with the geographical territory, makes more complex the younger people’s negotiations in crafting themselves vis-à-vis precarious employment opportunities and wider socio-economic dynamics in respect of precarious employment opportunities.     

Putting women back in their place. Reflections on slut-shaming,the case Asia Argento and Twitter in Italy

ABSTRACT

Compared to racist and ethnicist discourses, literature on sexist discourses – both off and on-line – as hate speech is relatively underinvestigated. This is partly due to the tendency to minimise accusations of sexism and to reframe misogyny as ‘acceptable’ by constructing it as a form of humour. We decided to focus on slut-shaming, one of the most virulent forms of hate speech, which has always existed but was boosted by social media, becoming a stable low-cost ingredient of today’s rape culture. We propose to consider online slut-shaming as a form of ‘technology-facilitated sexual violence’, where digital technologies are used to facilitate both virtual and face-to-face sexually based harms. According to feminist analysis of sexual violence, this would be a matter of power rather than sex: sex would be the weapon, not the motive. We have tested this research hypothesis by focusing on the Italian reception of the MeToo campaign, triggered by Asia Argento’s denunciation. More specifically, two Different Twitter corpora produced within the same five months period were examined by means of a quantitative and a qualitative methodology.     

Your work may be killing you! Workaholism,sleep problems and cardiovascular risk

This study tests the relationships between workaholism (i.e. working excessively and compulsively), sleep problems and cardiovascular risk in 537 employees from five Spanish hospitals. Four types of worker (i.e. workaholics, positive workers, compulsive workers and hard workers) were distinguished, and their health indicators were compared. The results showed that workaholics experienced significantly more sleep problems (i.e. morning tiredness, sleeping while driving and sleeping fewer hours both on weekdays and at weekends, with poorer quality), had higher relative risk scores, and consumed more caffeine and alcohol than the other patterns of worker (positive, compulsive and hard workers). Further analyses revealed that sleep problems fully mediated the relationship between workaholism (i.e. working excessively and compulsively) and cardiovascular risk. The study emphasizes the fact that being a workaholic might be a significant risk factor for having sleep problems and cardiovascular disease.     

The effects of the interactive use of management control systems on process and organizational innovation

This study examines how the interactive use of management control systems (iMCS) affects process and organizational innovation. Firstly, it is postulated that iMCS directly influences the development of process and organizational innovations. Secondly, we argue in favor of a moderating role of iMCS in the relationship between innovation and financial performance. Most studies of MCS and innovation have focused on new product development. However, process and organizational innovations follow innovation patterns that clearly differ from product innovation. The research model is empirically examined using data collected from a survey of 230 firms. Results from a structural model tested applying Partial Least Squares regression, controlling for size, family ownership, R&D, and product innovation, reveal that iMCS fosters process and organizational innovation. Results also suggest that iMCS could play a moderator role in the relationship between process innovation and financial performance. These findings highlight the role of iMCS in process and organizational innovation, expanding previous literature on Simons’ Levers of Control and innovation. The results are also discussed with regard to their managerial implications.     

HOW DOES PRODUCT MARKET COMPETITION SHAPE INCENTIVE CONTRACTS?

This paper studies the effect of product market competition on the explicit compensation packages that firms offer to their CEOs, executives and workers. We use a large sample of both traded and nontraded UK firms and exploit a quasi‐natural experiment associated to an increase in competition. The sudden appreciation of the pound in 1996 implied different changes in competition for sectors with different degrees of openness. Our difference in differences estimates show that a higher level of product market competition increases the performance pay sensitivity of compensation schemes, in particular for executives.
