Rubenstein, C.D. (author), den Hartog, E.A. (author), Deaton, A.S. (author), Bogerd, C.P. (author), de Kant, S. (author)A major concern for responders to hazardous materials (HazMat) incidents is the heat strain that is caused by fully encapsulated impermeable chemical protective suits. In a research project, funded by the US Department of Defense, the thermal strain experienced when wearing these suits was studied. One particular area of interest was the fluid...article 2017

(author)Background: Obesity frequently associates with the development of non-alcoholic fatty liver disease (NAFLD) and atherosclerosis. Chronic inflammation in white adipose tissue (WAT) seems to be an important driver of these manifestations.

Ly, V. (author), Roijendijk, L.L.M. (author), Hazebroek, H. (author), Tonnaer, C. (author), Hagenaars, M.A. (author)Freezing is a defensive response to acute stress that is associated with coping and alterations in attentional processing. However, it remains unclear whether individuals in high risk professions, who are skilled at making rapid decisions in emergency situations, show altered threat-induced freezing. Here we investigated the effect of incident...article 2017

Willemse, C.J.A.M. (author), Toet, A. (author), van Erp, J.B.F. (author)Social touch forms an important aspect of the human non-verbal communication repertoire, but is often overlooked in human–robot interaction. In this study, we investigated whether robot-initiated touches can induce physiological, emotional, and behavioral responses similar to those reported for human touches. Thirty-nine participants were...article 2017

Kallen, V.L. (author), Stubbe, J.H. (author), Zwolle, H.J. (author), Valk, P. (author)Background/aimIt is well known that physical strain is associated with increased cortisol production. And although mental stress elevates cortisol concentrations as well, little is known of the independent and/or combined effects of both on the secretion of cortisol. Aim of the study was to investigate the day-to-day cortisol dynamics associated...article 2017

Binsch, O. (author), van Wietmarschen, H. (author), Buick, F. (author)Optimism and perseverance are 2 important assets for soldiers to be able to perform competently in high-risk environments and to complete complex and stressful tasks. Traditionally, optimism is measured using questionnaires and most frequently in a retrospective manner, for example, after a mission is completed. As such, ability to persevere in...article 2016

Effects of different real-time feedback types on human performance in high-demanding work conditionsCohen, I. (author), Brinkman, W.P. (author), Neerincx, M.A. (author)Experiencing stress during training is a way to prepare professionals for real-life crises. With the help of feedback tools, professionals can train to recognize and overcome negative effects of stress on task performances. This paper reports two studies that empirically examined the effect of such a feedback system. The system, based on the...article 2016

Koldijk, S. (author), Neerincx, M.A. (author), Kraaij, W. (author)Employees often report the experience of stress at work. In the SWELL project we investigate how new context aware pervasive systems can support knowledge workers to diminish stress. The focus of this paper is on developing automatic classiers to infer working conditions and stress related mental states from a multimodal set of sensor data ...article 2016

Bernaards, C. (author), Hildebrandt, V.H. (author), Hendriksen, I.J. (author)Background. Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). Methods. The study sample consisted of...article 2016
