This paper explores the application of Self-Concepts, a Semantic-Differential Scale-based methodology, to evaluate a Serious Game designed for cognitive impairment assessment using the MoCA test and augmented reality (AR) for mobility analysis. A case study involved seven elderly participants. Despite some challenges in navigating the AR environment and cognitive tests, self-concept evaluations consistently demonstrated high user expectations and positive experiences with the digital artifact. This study validates the process and highlights the potential of Self-Concepts in assessing product acceptance within user groups.

Background: The aim of this study is to validate a newly developed nurses' self-efficacy sources inventory. We test the validity of a five-dimensional model of sources of self-efficacy, which we contrast with the traditional four-dimensional model based on Bandura's theoretical concepts. Methods: Confirmatory factor analysis was used in the development of the newly developed self-efficacy measure. Model fit was evaluated based upon commonly recommended goodness-of-fit indices, including the χ2 of the model fit, the Root Mean Square Error of approximation (RMSEA), the Tucker-Lewis Index (TLI), the Standardized Root Mean Square Residual (SRMR), and the Bayesian Information Criterion (BIC). Results: All 22 items of the newly developed five-factor sources of self-efficacy have high factor loadings (range .40-.80). Structural equation modeling showed that a five-factor model is favoured over the four-factor model. Conclusions and implications: Results of this study show that differentiation of the vicarious experience source into a peer- and expert based source reflects better how nursing students develop self-efficacy beliefs. This has implications for clinical learning environments: a better and differentiated use of self-efficacy sources can stimulate the professional development of nursing students.

Purpose – Against the background of current leadership theory, this research paper analyses and compares the leadership approaches of two outstanding leaders: Daniel Vasella, chairman of the leading Swiss pharmaceutical organization Novartis and Ricardo Semler, owner of the Brazilian conglomerate Semco. In contrast to many rather abstract, unpractical and pointlessly theoretical papers on leadership this analysis provides a more applied view of leadership by means of the life history approach delivering insight into both leaders’ development and leader personality. Methodology/approach – First, this paper locates the ideas and practices associated with the term “leadership” as a concept through theories that have developed over time and shows how the practices of leading can be derived and understood through chosen theories. Based on this, the specific characteristics and career paths of both leaders are presented and compared so that a final analysis of their leadership approach can be done. The paper is based on secondary sources such as peer-reviewed business journals and literature on leadership. Information about both leaders and their approach to leadership is gathered mainly from published interviews with them. Additional information on Semler is taken from his autobiography. Conclusions – It is difficult to identify an “essence” of leadership, whether that takes the form of personality characteristics or traits, charisma, the ability to transform people or organizations or a brain function. All presented theories of leadership seem to have their raison d’être. Both Vasella and Semler apply a combination of different attitudes and behaviours that characterize their leadership style containing elements of transformational, charismatic, ethical, servant and authentic leadership.
