The published literature has produced several definitions for the sense of presence in a simulated environment, as well as various methods for measuring it. The variety of conceptualizations makes it difficult for researchers to interpret, compare, and evaluate the presence ratings obtained from individual studies. Presence has been measured by employing questionnaires, physiological indices, behavioral feedbacks, and interviews. A systematic literature review was conducted to provide insight into the definitions and measurements of presence in studies from 2002 to 2019, with a focus on questionnaires and physiological measures. The review showed that scholars had introduced various definitions of presence that often originate from different theoretical standpoints and that this has produced a multitude of different questionnaires that aim to measure presence. At the same time, physiological studies that investigate the physiological correlates of the sense of presence have often shown ambiguous results or have not been replicated. Most of the scholars have preferred the use of questionnaires, with Witmer and Singer's Presence Questionnaire being the most prevalent. Among the physiological measures, electroencephalography was the most frequently used. The conclusions of the present review aim to stimulate future structured efforts to standardize the use of the construct of presence, as well as inspire the replication of the findings reported in the published literature.

Virtual reality (VR) offers novel ways to develop skills and learning. This technology can be used to enhance the way we educate and train professionals by possibly being more effective, cost-efficient, and reducing training-related risks. However, the potential benefits from virtual training assume that the trained skills can be transferred to the real world. Nevertheless, in the current published scientific literature, there is limited empirical evidence that links VR use to better learning. The present investigation aimed to explore the use of VR as a tool for training procedural skills and compare this modality with traditional instruction methods. To investigate skill development using the two forms of training, participants were randomly divided into two groups. The first group received training through an instructional video, while the second group trained in VR. After the training session, the participants performed the trained task in a real setting, and task performance was measured. Subsequently, the user's experienced sense of presence and simulator sickness (SS) was measured with self-report questionnaires. There were no significant differences between groups for any of the performance measures. There was no gender effect on performance. Importantly, the results of the present study indicate that a high sense of presence during the VR simulation might contribute to increased skill learning. These findings can be used as a starting point that could be of value when further exploring VR as a tool for skill development.

Modern head-mounted displays (HMDs) are a promising technology. Thanks to their affordable cost and versatility, HMDs are gaining attention from different sectors. However, the experience reported by the users of these technologies is sometimes negative. A number of people, when using an HMD, complain of various types of physical discomfort as well as symptoms like headache, disorientation, and nausea. These symptoms, developed during or after exposure to virtual environments, are commonly referred to with the term simulator sickness. Some scientific studies have shown that women are commonly more sensitive to simulator sickness. However, a gender imbalance in the susceptibility to simulator sickness has not been widely studied in the context of modern HMDs, and the studies that have been done have reported heterogeneous findings. The present systematic review aims to gather the pieces of evidence that support and oppose a gender difference in the susceptibility of simulator sickness in the framework of modern HMDs. We also aim to individuate other gender differences in the experience of the use of these technologies to establish whether there is sufficient evidence to support a gender discrepancy in the user experience.

Due to increased outsourcing in many industries, organizations are becoming larger and more interorganizationally complex and numerous operations now require cooperation among employees from different organizations. This paper presents a review of empirical literature addressing safety issues in complex interorganizational systems wherein the potential for major organizational accidents is present. Thematic analysis of the literature resulted in four main themes: economic pressures, disorganization, dilution of competence and organizational differences. The themes were viewed in light of different theoretical perspectives on organizational accident risk. The findings suggest that issues due to interorganizational complexity can hinder efficient safety management and thereby elevate the risk of organizational accidents. It is emphasized that further research is needed to better understand the implications of interorganizational complexity on safety management.

The aim of this study was to explore how human factors were taken into account in the development of a new type of drilling equipment. This study is part of a larger project on the understanding of human factors in the design and implementation of automated drilling technology. The principal study was a longitudinal study lasting 4 years that involved 43 interviews, offshore and onshore observations, and 2 surveys. MethodThe analysis in this paper is based on 7 informants who were either part of the design team or the paramount project team developing new automated drilling technology for an offshore oil-and gas-producing installation in the same development project, in addition to project documents. The informants were interviewed using semi-structured interviews, and grounded theory based on the coding process of Corbin and Strauss (1990) was used to analyse the data. 2 ResultsThe core category was found to be insufficient human factor analyses performed in the development phase due to the two main categories, namely 1) insufficient information coordination and 2) narrow focus in different phases of the project. This was found to contribute to increased costs, low user friendliness, and end users' insufficient knowledge of safe usage and potential risks. ConclusionOur conclusion was that homogenous top competence involving technical aspects contributed to developers' lack of understanding of the need for sufficient analyses of end user requirements and of the tasks that would be affected by the new technology. Hence, we argue that technological development could benefit from including human factors experts from the project's outset to bridge the gap between the lack of relevant information and sufficient information on which to base development decisions. In addition, we contend that performing human factors analyses throughout the development of a project would be beneficial due to the potential of hindering cultural aspects such as a non-questioning culture, which is viewed as a hazard in high-risk organizations.Keywords: human factors, human reliability, automated technology, safety, petroleum industry, technology development 3 IntroductionThe offshore oil and gas industry is considered a high-risk industry where minor incidents can lead to major accidents; thus, safety is a main priority (Årstad et al., 2010).Consequences of non-successful development and implementation of new technology have the potential of resulting in unwanted incidents and, in worst-case scenarios, major accidents.Because studies from the nuclear industry show that between 20 and 50% of incidents involve design mistakes (Taylor, 2007), it is important to involve strategies that ensure safety in technological development projects. Traditionally, the focus on safety in the development of new technology has been on technical aspects. Although lately there has been a growing focus on the human end users of the technology (ISO 11064, 2000;NORSOK, 2004 Saetren and Laumann (2015a) conducted a study where they found that too much trus...
