Engineering practice: Teaching ill-structured problem solving in an internship-like course

Engineering graduates who enter the work environment after finishing their studies are faced with completely different setting compared to the safe academy environment that they are used to. Main differences at the workplace include dealing with uncertainty on a daily basis, solving open-ended and/or ill-structured problems and having to manage teamwork and communication on different educational and professional levels. Students should be faced with these aspects of engineering practice during their studies in order to prepare for work. As conventional engineering curricula often do not provide opportunities for such a practice, we designed the internship-like course with general objective to provide this opportunity for final year students and to define teaching strategies that can support students in the transition from the academy to the workplace. In this paper we describe main issues and challenges of the learning experiences that we found during our action research over four 10 week courses, from 2010/2011 to 2012/2013.

Work Engagement in Serbia: Psychometric Properties of the Serbian Version of the Utrecht Work Engagement Scale (UWES)

Work engagement is defined as a positive, affective-motivational state of work-related well-being characterized by vigor, dedication and absorption. The Utrecht Work Engagement Scale (UWES) is the most frequently used measure of work engagement. The aim of this study was to analyze the psychometric properties of the Serbian versions of the UWES-17 and UWES-9. The sample consisted of 860 employees from a number of organizations and jobs across Serbia. Based on the UWES-17 findings, the data confirm both the three-factor and one-factor solutions by giving a slight advantage to the three-factor solution. As for the UWES-9, based on the PCFA and CFA, the one-factor solution was obtained as the preferred one. Taking into account the UWES-9 reliability and correlation patterns of its subscales with other well-being variables, both one- and three-factor solutions of the UWES-9 are suggested for future research. Serbian versions of both the UWES-17 and UWES-9 have satisfactory psychometric properties with high reliability, factorial structure in line with the theoretical model, and good predictive validity. The study contributes to enhanced understanding of work engagement by offering an insight from the Serbian cultural and economic context, significantly different from the UWES originating setting. There is still a need for exploring how employees from Serbia conceptualize work engagement, as well as for further, more stringent investigating of the cultural invariance of the UWES factorial structure.

Rocking at 81 and Rolling at 34: ROC Cut-Off Scores for the Negative Acts Questionnaire–Revised in Serbia

Researchers are still searching for the ways to identify different categories of employees according to their exposure to negative acts and psychological experience of workplace bullying. We followed Notelaers and Einarsen’s application of the ROC analysis to determine the NAQ-R cut-off scores applying a “lower” and “higher” threshold. The main goal of this research was to develop and test different gold standards of personal and organizational relevance in determining the NAQ-R cut-off scores in a specific cultural and economic context of Serbia. Apart from combining self-labeling as a victim with self-perceived health, the objectives were to test the gold standards developed as a combination of self-labeling with life satisfaction, self-labeling with intention to leave and a complex gold standard based on self-labeling, self-perceived health, life satisfaction and intention to leave taken together. The ROC analysis on Serbian workforce data supports applying of different gold standards. For identifying employees in a preliminary stage of bullying, the most applicable was the gold standard based on self-labeling and intention to leave (score 34 and higher). The most accurate identification of victims could be based on the most complex gold standard (score 81 and higher). This research encourages further investigation of gold standards in different cultures.

Acceptance of Workplace Bullying Behaviors and Job Satisfaction: Moderated Mediation Analysis With Coping Self-Efficacy and Exposure to Bullying

Previous research explored workplace climate as a factor of workplace bullying and coping with workplace bullying, but these concepts were not closely related to workplace bullying behaviors (WBBs). To examine whether the perceived exposure to bullying mediates the relationship between the climate of accepting WBBs and job satisfaction under the condition of different levels of WBBs coping self-efficacy beliefs, we performed moderated mediation analysis. The Negative Acts Questionnaire – Revised was given to 329 employees from Serbia for assessing perceived exposure to bullying. Leaving the original scale items, the instruction of the original Negative Acts Questionnaire – Revised was modified for assessing (1) the climate of accepting WBBs and (2) WBBs coping self-efficacy beliefs. There was a significant negative relationship between exposure to bullying and job satisfaction. WBB acceptance climate was positively related to exposure to workplace bullying and negatively related to job satisfaction. WBB acceptance climate had an indirect relationship with job satisfaction through bullying exposure, and the relationship between WBB acceptance and exposure to bullying was weaker among those who believed that they were more efficient in coping with workplace bullying. Workplace bullying could be sustained by WBB acceptance climate which threatens the job-related outcomes. WBBs coping self-efficacy beliefs have some buffering effects.

The relation of risk-taking propensity, professional preferences and the approach to the selection of future profession

Research has shown that risk-taking individuals choose professions that involve a high level of uncertainty, change or flexibility. The aim of this research was to study the relation between risk-taking propensity and professional preferences, as well as between different indicators of the approach to the selection of future profession and risk-taking propensity. The study was conducted on the sample of 583 students attending the final grade of secondary school. For the assessment of risk-taking propensity we used a modified version of the Evaluation of Risk scale (EVAR), while professional interests were investigated by the Test of Professional Orientation (TPO). In addition, we analysed certain indicators of the approach to the selection of profession that were interesting in the context of career counselling, namely: duration of the selection of profession, the number of professional preferences and readiness to make a professional choice. The results have shown that risk-taking propensity is significantly correlated with professional preferences where risk is an important job feature (such as professions in the field of security) as well as with the professions where risk is an important part of success (such as sports). It has also been shown that risk-taking individuals assess themselves as more ready to make decisions on their own professional choice. Based on the obtained results, it can be concluded that risk-taking propensity is an important characteristic that should be taken into account when studying professional preferences and the approach to the selection of future profession in adolescents.

Colors and geometric forms in the work process information coding

The aim of the research was to establish the meaning of the colors and geometric shapes in transmitting information in the work process. The sample of 100 students connected 50 situations which could be associated with regular tasks in the work process with 12 colors and 4 geometric forms in previously chosen color. Based on chosen color-geometric shape-situation regulation, the idea of the research was to find out regularities in coding of information and to examine if those regularities can provide meaningful data assigned to each individual code and to explain which codes are better and applicable represents of examined situations.
