Physical activity counteracts some of the negative consequences associated with chronic neurological diseases. Here, we describe the levels of physical activity and sports activity in patients with multiple sclerosis and chronic stroke and test compliance with the recommendation for health-promoting physical activity of the World-Health Organization. Secondly, we tested for differences between the groups of patients, and thirdly, we examined relationships between PA and Sport with psychological indicators of perceived energy and self-beliefs. Psychological constructs were assessed with validated measures from (...) different disciplines in Psychology. A statistical aim was to describe interpretations gained by parametric Bayesian and Null-Hypothesis-Significance Testing statistics on the example of the conducted tests for differences and relationships. Descriptive analyses revealed that pMS and pStroke complied with recommendations of the WHO, but with large variance indicating that patient groups are not homogenous. Tests for differences showed that the PA difference between pMS and pStroke can be attributed to the higher proportion of women in the pMS sample as they engage more in household chores. Tests for relationships showed that for pStroke, vitality, self-control, and self-efficacy were positively related to the level of sports activity. Furthermore, pStroke who were sport active had lower fatigue and higher self-control and self-efficacy scores than sport inactive people. Although they address slightly different questions, the Bayesian and the NHST approach led to similar general conclusions. (shrink)

Academic leaders in management from all over the world—including recent calls by the Academy of Management Shaw (Academy of Management Journal 60(3): 819–822, 2017)—have urged further research into the extent and use of questionable research practices (QRPs). In order to provide empirical evidence on the topic of QRPs, this work presents two linked studies. Study 1 determines the level of use of QRPs based on self-admission rates and estimated prevalence among business scholars in Indonesia. It was determined that if the (...) level of QRP use identified in Study 1 was quite high, Study 2 would be conducted to follow-up on this result, and this was indeed the case. Study 2 examines the factors that encourage and discourage the use of QRPs in the sample analyzed. The main research findings are as follows: (a) in Study 1, we found the self-admission rates and estimated prevalence of business scholars’ involvement in QRPs to be quite high when compared with studies conducted in other countries and (b) in Study 2, we found pressure for publication from universities, fear of rejection of manuscripts, meeting the expectations of reviewers, and available rewards to be the main reasons for the use of QRPs in Indonesia, whereas (c) formal sanctions and prevention efforts are factors that discourage QRPs. Recommendations for stakeholders (in this case, reviewers, editors, funders, supervisors, chancellors and others) are also provided in order to reduce the use of QRPs. (shrink)

Nowadays, almost everyone seems to agree that science is facing an epistemological crisis – namely the replicability crisis – and that we need to take action. But as to precisely what to do or how...
