The ETTO Principle: Efficiency-Thoroughness Trade-Off
Accident investigation and risk assessment have for decades focused on the human factor, particularly 'human error'. Countless books and papers have been written about how to identify, classify, eliminate, prevent and compensate for it. This bias towards the study of performance failures, leads to a neglect of normal or 'error-free' performance and the assumption that as failures and successes have different origins there is little to be gained from studying them together. Erik Hollnagel believes this assumption is false and that safety cannot be attained only by eliminating risks and failures.

The Oxford handbook of music and the body
The presence of the phenomenological body is central to music in all of its varieties and contradictions. With the explosion of scholarly works on the body in virtually every field in the humanities, the social as well as the biomedical sciences, the question of how such a complex understanding of the body is related to music, with its own complexity, has been investigated within specific disciplinary perspectives. The Oxford Handbook of Music and the Body brings together scholars from across these fields, providing a platform for the discussion of the multidimensional interfaces of music and the body. The book is organized into six sections, each discussing a topic that defines the field: the moving and performing body; the musical brain and psyche; embodied mind, embodied rhythm; the disabled and sexual body; music as medicine; and the multimodal body. Connecting a wide array of diverse perspectives and presenting a survey of research and practice, the Handbook provides an introduction into the rich world of music and the body.

Job engagement, perceived organizational support, high-performance human resource practices, and cultural value orientations: A cross-level investigation
Drawing on social exchange theory, we developed and tested a cross-level model of organizational-level predictors of job engagement. Specifically, we examined the impact of high-performance human resource (HR) practices on employee engagement and work outcomes. Based on a sample of 605 employees, their immediate supervisors, and HR managers from 130 companies, our results indicated that high-performance HR practices were directly related to job engagement as well as indirectly related through employees’ perceived organizational support. In turn, job engagement was positively related to in-role performance and negatively related to intent to quit. Culture was found to act as a critical contextual factor, as our results also revealed that the relationship between HR practices and perceived organizational support was stronger when collectivism was high and when power distance orientation was low. Overall, the findings shed new light on the processes and conditions through which employee work-related outcomes are enhanced owing to high-performance HR practices.

Is CO2 an Indoor Pollutant? Direct Effects of Low-to-Moderate CO2 Concentrations on Human Decision-Making Performance
Associations of higher indoor carbon dioxide (CO2) concentrations with impaired work performance, increased health symptoms, and poorer perceived air quality have been attributed to correlation of indoor CO2 with concentrations of other indoor air pollutants that are also influenced by rates of outdoor-air ventilation.
We assessed direct effects of increased CO2, within the range of indoor concentrations, on decision making.
Twenty-two participants were exposed to CO2 at 600, 1,000, and 2,500 ppm in an office-like chamber, in six groups. Each group was exposed to these conditions in three 2.5-hr sessions, all on 1 day, with exposure order balanced across groups. At 600 ppm, CO2 came from outdoor air and participants' respiration. Higher concentrations were achieved by injecting ultrapure CO2. Ventilation rate and temperature were constant. Under each condition, participants completed a computer-based test of decision-making performance as well as questionnaires on health symptoms and perceived air quality. Participants and the person administering the decision-making test were blinded to CO2 level. Data were analyzed with analysis of variance models.
Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06-0.56), but performance on the focused activity scale increased.
Direct adverse effects of CO2 on human performance may be economically important and may limit energy-saving reductions in outdoor air ventilation per person in buildings. Confirmation of these findings is needed.

Digital bodies : creativity and technology in the arts and humanities
This book explores technologies related to bodily interaction and creativity from a multi-disciplinary perspective. By taking such an approach, the collection offers a comprehensive view of digital technology research that both extends our notions of the body and creativity through a digital lens, and informs of the role of technology in practices central to the arts and humanities. Crucially, Digital Bodies foregrounds creativity, the interrogation of technologies and the notion of embodiment within the various disciplines of art, design, performance and social science. In doing so, it explores a potential or virtual new sense of the embodied self. This book will appeal to academics, practitioners and those with an interest in not only how digital technologies affect the body, but also how they can enhance human creativity.

Bioenhancement Technologies and the Vulnerable Body
The field of biomedical technology has experienced rapid growth in recent years. New technologies promise to diagnose, treat, and prevent human diseases. Increasingly, however, the ability of these technologies to \"enhance\" normal human functioning beyond what is necessary to restore or sustain health has raised considerable debate about the proper limits of biotechnology. Whereas the public-facing proponents of bioenhancements tend to come from privileged positions in society, Bioenhancement Technologies and the Vulnerable Body seeks to analyze the nuances of bioenhancement from the perspective of those who are often marginalized in bioethical discussions. Any moral assessment of technology must consider its effects on all people, principally those who have not benefited equally from technological advancements. From the premise that minority perspectives yield new insights into biomedical enhancements, this volume centers the bodies of persons who are vulnerable to health disparities--particularly persons with disabilities and persons of color. Contributors critically examine bioenhancement technologies with two key questions in mind: What does it mean to be human? and What does it mean to be vulnerable? Each chapter uses distinct Christian theological methods and ontological suppositions to reflect on the distinctiveness of human creatureliness in relation to technology and what difference bioenhancement might make for our conceptions of vulnerability. Bioenhancement Technologies and the Vulnerable Body is aimed primarily at Christian scholars and graduate students already conversant in bioethics but will also appeal to contextual theologians and others not well-versed in these debates.
