Temporary staffing services: a data mining perspective

Research on the temporary staffing industry discusses different topics ranging from workplace safety to the internationalization of temporary labor. However, there is a lack of data mining studies concerning this topic. This paper meets this void and uses a financial dataset as input for the estimated models. Bagged decision trees were utilized to cope with the high dimensionality. Two bagged decision trees were estimated: one using the whole dataset and one using the top 12 predictors. Both had the same predictive performance. This means we can highly reduce the computational complexity, without losing accuracy

The relationship evolutionary process change practices, role stressor and internal customer satisfaction in Jordan’s telecommunication companies

This study investigates the moderating effect of the role stressor on the relationship between evolutionary process change (EPC) practice factors (leadership change, behavioural change, structural change, technological change, and cultural change) and internal customer satisfaction (ICS). Self-reported surveys were carried out among 354 respondents from three telecommunication companies in Jordan. Both multiple and a three-step hierarchical regression analysis were used to test the hypotheses. Overall, the findings revealed that leadership change, behavioural change, structural change, technological change, and cultural change are significant predictors of internal customer satisfaction. However, mixed results were found on the moderating role of the role stressors. While the study found support for the moderating effect of role conflict on the relationship between structural change and technological change on internal customer satisfaction, role ambiguity moderated only the relationship between cultural change and internal customer satisfaction. The study contributes to the body of knowledge by providing insight into the key factors that affect internal customer satisfaction. It also provides additional insight into the moderating role of the role stressor, in particular role conflict and role ambiguity, in enhancing internal customer satisfaction in the telecommunication industry. The study also highlights the limitations and offers recommendations for future researc

Cartoons as interdiscourse : a quali-quantitative analysis of social representations based on collective imagination in cartoons produced after the Charlie Hebdo attack

The attacks against Charlie Hebdo in Paris at the beginning of the year 2015 urged many cartoonists – most professionals but some laymen as well – to create cartoons as a reaction to this tragedy. The main goal of this article is to show how traumatic events like this one can converge in a rather limited set of metaphors, ranging from easily recognizable topoi to rather vague interdiscourses that circulate in contemporary societies. To do so, we analyzed 450 cartoons that were produced as a reaction to the Charlie Hebdo attacks, and took a quali-quantitative approach that draws both on discourse analysis and semiotics. In this paper, we identified eight main themes and we analyzed the five ones which are anchored in collective imagination (the pen against the sword, the journalist as a modern hero, etc.). Then, we studied the cartoons at figurative, narrative and thematic levels thanks to Greimas’ model of the semiotic square. This paper shows the ways in which these cartoons build upon a memory-based network of events from the recent past (particularly 9/11), and more generally on a collective imagination which can be linked to Western values.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
