Profiles of doctoral students’ experience of ethics in supervision:an inter-country comparison

Abstract The purpose of this study was to examine variation in doctoral students’ experiences of ethics in doctoral supervision and how these experiences are related to research engagement, burnout, satisfaction, and intending to discontinue PhD studies. Data were collected from 860 doctoral students in Finland, Estonia, and South Africa. Four distinct profiles of ethics experience in doctoral supervision were identified, namely students puzzled by the supervision relationship, strugglers in the ethical landscape, seekers of ethical allies, and students with ethically trouble-free experiences. The results show that the profiles were related to research engagement, satisfaction with supervision and studies, and burnout. Not experiencing any major ethical problems in supervision was associated with experiencing higher engagement and satisfaction with supervision and doctoral studies and low levels of exhaustion and cynicism. Similar profiles were identified across the countries, yet with different emphases. Both Estonian and South African PhD students were overrepresented in the profile of students with ethically trouble-free experiences, while the Finnish students were underrepresented in this profile. The Finnish PhD students were overrepresented among the seekers of ethical allies. Profiles provide information that can alert supervisors and administrators about the extent of the risk of burnout or discontinuing of PhD studies based on students’ negative experiences of the ethics in supervision

Mixed methods in sustainable tourism research: an analysis of prevalence, designs and application in JOST (2005–2014)

This article analyses the use of mixed methods in papers published in the Journal of Sustainable Tourism over the 10 years, 2005–2014. First, a content analysis of the articles shows that mixed methods are used primarily for expansion and development of results, and less often for triangulation or complementarity. Sequential designs are slightly more popular than simultaneous designs, with qualitative research preceding the quantitative element. In the majority of cases, both the quantitative and qualitative methods have equivalent importance, yet where one is dominant, this is usually the quantitative part. Second, we contextualise the content analysis by exemplifying the use of mixed methods in selected papers, using commentary from authors who have recently published mixed methods papers. We reflect on the reasons for, strengths and weaknesses of using mixed methods, and we argue that mixed methods provide sustainable tourism academics with more opportunities for pragmatic transformative research for societal change, and increasing research reliability in relation to social desirability bias, stakeholder comparisons and transdisciplinarity. The paper notes the need for greater understanding of mixed methods by researchers, its special value and growing importance in sustainable tourism research, and its challenges and strengths for authors and editors

Prelamin A causes aberrant myonuclear arrangement and results in muscle fiber weakness.

Physiological and premature aging are frequently associated with an accumulation of prelamin A, a precursor of lamin A, in the nuclear envelope of various cell types. Here, we aimed to underpin the hitherto unknown mechanisms by which prelamin A alters myonuclear organization and muscle fiber function. By experimentally studying membrane-permeabilized myofibers from various transgenic mouse lines, our results indicate that, in the presence of prelamin A, the abundance of nuclei and myosin content is markedly reduced within muscle fibers. This leads to a concept by which the remaining myonuclei are very distant from each other and are pushed to function beyond their maximum cytoplasmic capacity, ultimately inducing muscle fiber weakness
