Epidemiology is often described as “the basic science of public health” (Savitz, Poole & Miller, 1999; Syme & Yen, 2000). This description suggests both a close association with public health practice, and the separation of “pure” scientific knowledge from its application in the messy social world. Although the attainability of absolute objectivity is rarely claimed, epidemiologists are routinely encouraged to “persist in their efforts to substitute evidence for faith in scientific reasoning” (Stolley, 1985, p. 38) and reminded that “public health decision makers gain little from impassioned scholars who go beyond advancing and explaining the science to promoting a specific public health agenda” (Savitz et al., 1999, p. 1160). Epidemiology produces authoritative data that are transformed into evidence which informs public health. Those data are authoritative because epidemiology is regarded as a neutral scientific enterprise. Because its claims are grounded in science, epidemiological knowledge is deemed to have “a special technical status and hence is not contestable in the same way as are say, religion or ethics” (Lock, 1988, p. 6). Despite the veneer of universality afforded by its scientific pedigree, epidemiology is not a static or monolithic discipline. Epidemiological truth claims are embodied in several shifting paradigms that span the life of the discipline. Public health knowledges and practices, competing claims internal and external to epidemiology, and structural conditions (such as current political economies, material technologies, and institutions) provide important contexts in which certain kinds of epidemiological knowledge are more likely to emerge.

Ponders on whether Abraham Flexner was responsible for the change in medical education in North America in the early 20th century, owing to his report of 1910. Tries to demonstrate that medical education in the USA was part of a greater whole of major changes at that time. Concludes, though there was a philanthropic influence, Flexner (who refused to accept credit for change) was not the father of the medical reform plan.

Interest in psychological resilience has grown rapidly in the last couple of decades (Britt, Sinclair, & McFadden, 2016; King & Rothstein, 2010; Youssef & Luthans, 2007). Psychological resilience occurs when a person can “recover, re-bound, bounce-back, adjust or even thrive” in the face of adversity (Garcia-Dia, DiNapoli, Garcia-Ona, Jakubowski, & O’flaherty, 2013, p. 264). As such, resilience can be conceptualized as a state-like and malleable construct that can be enhanced in response to stressful events (Kossek & Perrigino, 2016). It incorporates a dynamic process by which individuals use protective factors (internal and external) to positively adapt to stress over time (Luthar, Cicchetti, & Becker, 2000; Rutter, 1987). Building on the dual-pathway model of resilience, we integrate adaptive and proactive coping to the resilience development process and add a heretofore unexamined perspective to the ways in which resilience changes over time. We propose that resilience development trajectories differ depending on the type of adversity or stress experienced in combination with the use of adaptive and proactive coping. We outline the need for future longitudinal studies to examine these relationships and the implications for developing resilience interventions in the workplace.

The purpose of this paper is to present the results of a study exploring the emerging field of data science from the library and information science (LIS) perspective.

Content analysis of research publications on data science was made of papers published in the Web of Science database to identify the main themes discussed in the publications from the LIS perspective.

A content analysis of 80 publications is presented. The articles belonged to the six broad categories: data science education and training; knowledge and skills of the data professional; the role of libraries and librarians in the data science movement; tools, techniques and applications of data science; data science from the knowledge management perspective; and data science from the perspective of health sciences. The category of tools, techniques and applications of data science was most addressed by the authors, followed by data science from the perspective of health sciences, data science education and training and knowledge and skills of the data professional. However, several publications fell into several categories because these topics were closely related.

Only publication recorded in the Web of Science database and with the term “data science” in the topic area were analyzed. Therefore, several relevant studies are not discussed in this paper that either were related to other keywords such as “e-science”, “e-research”, “data service”, “data curation”, “research data management” or “scientific data management” or were not present in the Web of Science database.

The paper provides the first exploration by content analysis of the field of data science from the perspective of the LIS.

Cardiovascular diseases (CVDs) are responsible for one-third of global deaths. Work stress is a major risk factor for CVDs in the workforce. Construction professionals endure excessive work stress, yet their vulnerability to CVDs remains underexplored. The study investigated the prevalence of CVDs among construction professionals and its relationships to job stressors, stress coping methods and socio-demographics.

An online survey was conducted among construction professionals in Australia wherein data related to job stressor experiences, stress management methods adopted, and incidents of CVDs were collected. Structural path analysis was conducted to discover associations.

Junior level professionals reported higher incidents of angina and heart muscle weakening than others. Statistically significant positive associations were discovered between the reported CVDs, and job stressors such as excessive workload, unpredictable work hours, lack of support, discrimination and work–life conflict and negative stress coping methods such as consuming alcohol and/or drugs, emotional eating and aggression. However, no evidence was found to support the claim that demographic factors such as age and gender were also risk factors for CVDs.

The workers' compensation system provides financial protection to injured employees. It extends similar protection for work-related illnesses; however, it is more difficult to prove work-related causes for illnesses. The study provides scientific evidence to support the recognition of CVDs among construction professionals as work-related diseases, mediated by work stress.

Drawing on the scientific literature, the purpose of this paper is to elucidate the harmful effects of toxic stress on the developing brain. It explains how severe, chronic adversity during development, in the absence of responsive caregiving, can impair brain architecture. It also outlines policy implications for preventing or mitigating the effects of toxic stress in early childhood.

The National Scientific Council on the Developing Child, based at the Center on the Developing Child at Harvard University, is a multidisciplinary, multiuniversity panel of scholars that seeks to bring science to bear on public decision making. Council members selected excessive stress as a topic meriting translation for a general audience and conducted extensive peer review in drafting the paper's key scientific concepts.

The paper discusses how healthy development can be derailed by excessive or prolonged activation of the biological stress response systems and how that increases lifetime risk for certain behavioural and physiological disorders. It finds that supportive relationships with caregivers can help buffer the negative consequences of toxic stress.

The paper calls for improvements to family support programmes, mental health services, and the quality and availability of early care and education.

This paper describes an original taxonomy of positive, tolerable, and toxic stress and demonstrates the need to translate scientific knowledge about the developing brain into actionable strategies for the prevention and treatment of the effects of adverse childhood experiences.

The purpose of this paper is to explore in what way gradually increasing teachers’ theory-based instruction affects the students’ learning outcomes, illustrated by the example of learning how to regulate body tension in the upper secondary school.

In total, 72 students from four classes participated in the study. The way the students were offered to understand “regulation of tension” was designed by variation theory, and the method used was learning study, an iterative process whereby the results from the first lesson are the basis for the design of the next implementation in a new group of students.

There is a significant increased learning outcome in all four lessons, but in Lesson D, where the highest increase (129 percent) was found, all students improved their results. The use of the theoretical framework had effect on the teachers to vary only the most important aspects in the instruction in the last cycle, where the features chiselled out during the study (e.g. heart rate, respiration, muscle tension) were contrasted more clearly, which had an impact on the students’ learning. Based on the theoretical framework, the teachers got more skilled at experiencing what should vary and what should be kept invariant in order to facilitate the students’ learning. In the last intervention, the teachers found one pattern of variation which was more powerful than the previous. In this one, the physical activities were kept invariant, but different responses of the sympathetic nervous system were contrasted, one at a time, to establish knowledge of different bodily responses to tension.

Learning study has mainly been used in subjects such as Mathematics or other theoretical issues but this paper describes in what way learning study can be used in PE. So second, the result of this study contributes to knowledge about how students’ learning outcome in PEH can increase by directing focus on an object of learning rather than actual learning activity. The object of learning in this study is to learn to regulate tenseness and the learning outcomes have been analyzed in the perspective of variation theory.

The purpose of this paper is to explore whether challenging experiences on development programmes would simulate leadership challenges and therefore stimulate the body’s autonomic nervous system response. The authors also aimed to determine whether increase in autonomic arousal would be related to learning, and/or moderated by personality variables.

The research used heart rate (HR) monitors to measure HR continuously over a two-day simulated learning experience. This was used to calculate autonomic arousal which was taken to be the difference between resting HR measured during sleep and HR during critical incidents (CIs) (HR). The authors correlated this with self-reports of learning immediately after, and one month after, the programme to assess the impact of autonomic arousal on perceived learning, as well as with variety of psychometric measures.

The research found significant correlations between (HR) during CIs and perceived learning which were not related to personality type. The research also found a significant correlation between (HR) and learning during a control event for individuals with “approach” personalities.

Whilst a significant result was found, the sample size of 28 was small. The research also did not empirically assess the valence or intensity of the emotions experienced, and used only a self-report measure of learning. Future research should replicate the findings with a larger sample size, attempt to measure these emotional dimensions, as well as obtain perceptions of learning from direct reports and line managers.

The findings from the research help clarify the mechanisms involved in the effectiveness of experiential learning, and contribute to the understanding of the influence of personality type on perceived learning from experiential methodologies. Such understanding has implications for business schools and learning and development professionals, suggesting that development experiences that challenge leaders are likely to result in learning that is longer lasting.

The research extends the literature regarding the value of learning through experience, the role of autonomic arousal on learning, and the impact of negative emotions on cognition. The research makes a unique contribution by exploring the impact of experience on arousal and learning in a simulated learning experience and over time, by demonstrating that simulated experiences induce emotional and physiological responses, and that these experiences are associated with increased learning.
