  The purpose of this chapter is to review qualitative research on user experiences with internet interventions for depression and present original results from in-depth interviews from a preventive unguided intervention for postpartum depression. The first part reviews the literature on qualitative studies of client experiences and perceptions of internet interventions for depression. The next part describes original data from a study investigating participants' experiences using semi-structured interviews, following the modified SWOT-format (i.e., strengths, weakness, opportunities, and threats). In total, 10 pregnant and postpartum women aged 28 to 41 were interviewed. Insights from the current review and study are used as a point of departure for discussing future directions in research on internet interventions for depression. This chapter should be valuable for clinicians, researchers, and other health professionals interested in the applicability of internet interventions for their clients, design of future studies, and development of internet interventions.

  Chatbots are predicted to play a key role in customer service. Users’ trust in such chatbots is critical for their uptake. However, there is a lack of knowledge concerning users’ trust in chatbots. To bridge this knowledge gap, we present a questionnaire study (N = 154) that investigated factors of relevance for trust in customer service chatbots. The study included two parts: an explanatory investigation of the relative importance of factors known to predict trust from the general literature on interactive systems and an exploratory identification of other factors of particular relevance for trust in chatbots. The participants were recruited as part of their dialogue with one of four chatbots for customer service. Based on the findings, we propose an initial model of trust in chatbots for customer service, including chatbot-related factors (perceived expertise and responsiveness), environment-related factors (risk and brand perceptions), and user-related factors (propensity to trust technology).

  Chatbots are increasingly offered as an alternative source of customer service. For users to take up chatbots for this purpose, it is important that users trust chatbots to provide the required support. However, there is currently a lack in knowledge regarding the factors that affect users’ trust in chatbots. We present an interview study addressing this knowledge gap. Thirteen users of chatbots for customer service were interviewed regarding their experience with the chatbots and factors affecting their trust in these. Users’ trust in chatbots for customer service was found to be affected (a) by factors concerning the specific chatbot, specifically the quality of its interpretation of requests and advise, its human-likeness, its self-presentation, and its professional appearance, but also (b) by factors concerning the service context, specifically the brand of the chatbot host, the perceived security and privacy in the chatbot, as well as general risk perceptions concerning the topic of the request. Implications for the design and development of chatbots and directions for future work are suggested.

  The present study aimed to identify organizational climate dimensions that are salient for police investigation performance and to explicate the mechanisms of the relationship between organizational climate and investigation performance. We conducted 38 semistructured interviews with participants at three job levels of police investigative work (chiefs of police, n = 11, senior investigating officers, n = 14, detectives, n = 13) in 11 Norwegian police districts. We analyzed the interview data by using a model of organizational climate based on the competing values framework (Quinn & Rohrbaugh, 1983). Two types of climate, human relations climate and rational goal climate, were perceived to enhance investigation performance. The findings indicate that a human relations climate enhances investigation performance by developing collective human capital and by supporting internal and external cooperation and coordination of resources. Moreover, the findings suggest that a rational goal climate increases investigation performance by encouraging planning, goal setting, and task focus.

  Background: Depression is one of the most common mental health problems among adults, but effective treatments are not widely accessible. The Internet holds promise as a cost-effective and convenient delivery platform of interventions for depression. However, studies suggest that Internet interventions are not widely available in routine settings. Objective: The aim of this study was to review the literature and examine whether there are systematic differences in reporting of the various implementation components on Internet interventions for depression, and then to examine what is known about and is characteristic of the implementation of these Internet interventions in regular care settings. Methods: We performed a scoping review, drawing upon a broad range of the literature on Internet interventions for depression in regular care, and used the active implementation framework to extract data. Results: Overall, the results suggested that knowledge about the implementation of Internet interventions for depression in regular care is limited. However, guided support from health professionals emphasizing program adherence and recruitment of end users to the interventions emerged as 2 main themes. We identified 3 additional themes among practitioners, including their qualifications, training, and supervision, but these were scarcely described in the literature. The competency drivers (ie, staff and user selection, training, and supervision) have received the most attention, while little attention has been given to organizational (ie, decision support, administration, and system intervention) and leadership drivers. Conclusions: Research has placed little emphasis on reporting on the implementation of interventions in practice. Leadership and organizational drivers, in particular, have been largely neglected. The results of this scoping review have implications for future research and efforts to successfully implement Internet interventions for depression in regular care.

  The internet seems promising for delivering interventions to enhance well-being in a normal population. The aim of this study was to test the effects of an internet-based positive psychology intervention targeting gratitude, pleasant activities, strengths, mastery, acts of kindness, optimism, flow, attributions, and mindfulness. One-hundred and twelve participants were randomized to the intervention and 94 to the control group, and data were collected at baseline, one, two, and six months after intervention onset. The balance of positive to negative affect increased over time among participants in the intervention group (unstandardized beta coefficient [B] = 0.07, p < 0.01), as compared to the controls (B = 0.02, p = 010). The intervention worked equally well regardless of participants’ gender, age, or education. However, optimism did not mediate the effect of the intervention on affect balance. In conclusion, the intervention had a small, but significant effect on affect balance among healthy adults.

  The aim of the present study was to identify central dimensions and develop a model of organizational climate in large-scale project organizations in the oil and gas industry. Interviews with 18 employees (15 men, 3 women) in a project organization in the Norwegian oil and gas industry were content-analyzed on two models: The global instrument, the Organizational Climate Measure (OCM) based on the Competing Values Framework, and the domain-specific instrument, Project People Survey (PPS). The findings indicate that a climate characterized by a strong focus on a) communication and cooperation with actors in the external environment such as vendors, and b) internal cooperation and communication with other projects and with the line organization, is perceived as critical to success in large-scale projects in the oil and gas industry. We propose a new model called the Organizational Climate Measure for Large-Scale Project Organizations in the Oil and Gas Industry (OCMP).

  What is it that designers talk about as mattering in their professional competencies? In this article, we empirically investigated industrial designers’ own assumptions on their design practice in relation to innovation. In applying a method potentially suitable for design research, interview statements from design professionals (n=17) were categorised according to 12 pre-selected categories of potential design core competencies. Of a total of 2,267 statements, 1,990 were classified as related to design competence. A qualitative classification of the statements revealed that 1,259 (63.3%) of these could be classified under the pre-set categories. The results showed that out of the 12 categories, ‘creativity’, ‘particular design methods and techniques’ and ‘user’ were emphasised. From the remaining statements, two additional categories were revealed: ‘teamwork’ and ‘project management’. These results can be used to reveal design professionals’ self-understanding of their contributions to innovation processes.

  Background: Stress is commonly experienced by many people and it is a contributing factor to many mental and physical health conditions, However, few efforts have been made to develop and test the effects of interventions for stress. Objective: The aim of this study was to examine the effects of a Web-based stress-reduction intervention on stress, investigate mindfulness and procrastination as potential mediators of any treatment effects, and test whether the intervention is equally effective for females as males, all ages, and all levels of education. Methods: We employed a randomized controlled trial in this study. Participants were recruited online via Facebook and randomly assigned to either the stress intervention or a control condition. The Web-based stress intervention was fully automated and consisted of 13 sessions over 1 month. The controls were informed that they would get access to the intervention after the final data collection. Data were collected at baseline and at 1, 2, and 6 months after intervention onset by means of online questionnaires. Outcomes were stress, mindfulness, and procrastination, which were all measured at every measurement occasion. Results: A total of 259 participants were included and were allocated to either the stress intervention (n=126) or the control condition (n=133). Participants in the intervention and control group were comparable at baseline; however, results revealed that participants in the stress intervention followed a statistically different (ie, cubic) developmental trajectory in stress levels over time compared to the controls. A growth curve analysis showed that participants in the stress intervention (unstandardized beta coefficient [B]=–3.45, P=.008) recovered more quickly compared to the control group (B=–0.81, P=.34) from baseline to 1 month. Although participants in the stress intervention did show increases in stress levels during the study period (B=2.23, P=.008), long-term stress levels did decrease again toward study end at 6 months (B=–0.28, P=.009). Stress levels in the control group, however, remained largely unchanged after 1 month (B=0.29, P=.61) and toward 6 months (B=–0.03, P=.67). Mediation analyses showed nonlinear (ie, cubic) specific indirect effects of mindfulness and a linear specific indirect effect of procrastination on stress. In simple terms, the intervention increased mindfulness and decreased procrastination, which was related to lower stress levels. Finally, the effect of the stress intervention was independent of participants’ gender, age, or education. Conclusions: The results from this randomized controlled trial suggest that a Web-based intervention can reduce levels of stress in a normal population and that both mindfulness and procrastination may be important components included in future eHealth interventions for stress.

  Several studies have documented the occurrence of high ventilation rates during cardiopulmonary resuscitation, but to date, there have been no scientific investigation of the causes of hyperventilation. The objective of the current study was to test the effects of socio-emotional stressors on lay rescuers’ ventilation rate in a simulated resuscitation setting using a manikin model. A within-subjects experiment with randomized order of conditions tested lay rescuers’ ventilation rate on an intubated manikin during exposure to socio-emotional stressors and during a control condition where no external stressors were present. Ventilation rates and subjective workload were significantly higher during exposure to socio-emotional stressors than during the control condition. All but one of the nine participants ventilated at a higher ventilation rate in the experimental condition. All nine participants rated the subjective workload to be higher during exposure to socio-emotional stressors. Hence, exposure to socio-emotional stressors is associated with increased ventilation rates performed by lay rescuers during simulated cardiac arrest using a manikin model. These findings might have implications for the understanding of the type of situations which hyperventilation may occur. Awareness of these situations may have implications for training of lay rescues.

  The aim of this article was to investigate the generalizability of existing research on the relationship between organizational climate and innovation in the service sector. The study was carried out in four large departments in an international service organization (N=409), representing different industries in the service sector. The Norwegian Organizational Climate Measure (NOCM) was administered as a measure of the climate of the organization. Encouragement and support of new ideas were positively related to innovation, whereas holding on to established ways of performing work was negatively related to innovation. The results indicate that certain dimensions of the organizational climate are related to innovation, and of importance for innovation in service sector organizations. The present study discusses the generalizability of prior findings, the relationship between climate and innovation in the service sector, and suggests how organizations within the service sector can promote innovation.

  This article investigates the relationship between the control situation framework, as presented by Bjørkli et al. (Cogn Technol Work 9:67–80, 2007), and observed operator action and communication in high-speed craft operation in the Norwegian Royal Navy. The reported data include two series of events during sailing in the Norwegian archipelago where uncertainty of ship position, challenges of manoeuvring and navigation strategies are addressed. The results indicate that the navigators perform actions and communicate in accordance with the key features of the control situation framework, and thus adapt to the interrelation between control possibilities and control requirements. The navigators were guided by explicit knowledge of the functional characteristics of psychical and temporal dynamics, which were actualized in manoeuvring. It indicates that the control situation framework can be used to describe the models the operators use.

  The idea behind M-SWOT is to assess the organization by way of mapping the participants’ responses to open and general questions onto specific, research based models in a particular domain; in this case innovation climate. The present article attempts to conceptually validate SWOT by way of providing a link to the Organizational Climate Measure (OCM), and to demonstrate discriminatory validity of SWOT towards other related, but unspecific models (the Job Characteristics Model (JCM)), based on SWOT interviews with 15 managers in two highly innovative Norwegian companies. The hypotheses are that there will be a positive correlation between the OCM dimensions and the SWOT statements; that the four quadrants of OCM will cover the SWOT statements in a particular order, and that more SWOT statements will be aligned with OCM than JCM. All hypotheses were confirmed. The results indicate that an M-SWOT approach to innovation climate development is viable with respect to the type of content that the SWOT interviews elicit.

  The present article attempts to conceptually validate two established surveys for measuring psychosocial work environment; The General Nordic Questionnaire for Psychological and Social Factors at Work (QPSNordic), and the Organizational Climate Measure (OCM). Five respondents in a financial institution were asked to reflect freely on the topic of the psychosocial work environment of the company, only guided by the SWOT format. The main hypothesis was that even though QPSNordic is comprehensive and developed specifically for measuring psychosocial work environment, the thematically broader OCM – with less items – would capture more of the statements from the transcribed interviews. In addition, it was assumed that the SWOT format would provide statements not covered by any of the statements. Both hypotheses were confirmed, and OCM proved to be more sensitive to the statements than did the QPSNordic. The SWOT format turned out to be even more sensitive, but this might be due to the nature of the SWOT questions, rather than the conceptualizations of the respondents.

  The control situation framework presented by Petersen (Cogn Technol Work 6(4):266–274, 2004) is elaborated upon in the context of military high-speed craft navigation. An observational study was done on a military navigational exercise in Indre Folda, a stretch of particularly demanding confined waters in Norway. The concept of control strategies is presented as a term related to how navigators choose to take out the control possibilities present in the system. Control actions are viewed as actions that fix the control demands and control possibilities over longer time-scales. Control strategies are different from control actions in that they continuously alter the control demands and control possibilities through its execution.

  A comparison of high-speed craft navigation in simulated and real settings was performed. Three route-segments differing in complexity was analyzed by comparing the speed and trajectory variance between the simulator-based navigation and the real navigation. Significant differences in speed and trajectory variance was found, but these differences were not consistent over the segments. However, the differences in speed and trajectory variance could be understood by taking into an interaction between the lack of risk involved in simulator navigation relative to real navigation, and the complexity of the segments analyzed.

  Natural (unconstrained) learning can be described as an integral interaction between internal and external mental representations. On the other hand, constrained learning (e.g. traditional teaching in schools and universities), draw heavily on processing of internal mental models. This is a fundamental problem, because mental models can be expanded first and foremost through a process of externally imposed conflicts. Instead of focusing on developing memory-enhancing techniques, such as chunking or mnemonics, cognitive psychology should turn its focus into studying ways to avoid normative rationalistic scripts. Several techniques for script expansion are suggested. All focus on the same issue; how to impose external conflict into rationalised internal mental models.

  The deep integration of technology in our modern society forces us to rethink the relationship humans have to their surroundings. The rise of complex sociotechnical systems denotes how humans and technology have entered a symbiotic relationship where the coordinated and fluent interaction between us and technology is a crucial condition for modern societies to function. The disharmony in the relationship between humans and technology has immediate and serious consequences. Accidents and failed operations in transport, incomprehensible user interfaces, and failure to learn from experience are all examples from everyday life suggesting that the understanding of human-technology relationships is not sufficient. This book investigates how humans relate to technology in our modern society, and how our basic assumption of human thought and behaviour guide our efforts to improve and control technology. The fact is that the skilled use of technology in expert systems and everyday life challenges the traditional conception of humans and technology as two separate elements in the analysis of work. This book shows how this dualism is evident and problematic in a wide range of areas, such as investigation of human error in accidents, case studies of innovative interface solutions, simulator training strategies, analysis of work practices in complex systems, and traffic safety research. This book is written for researchers, students and professionals, to supplement the ongoing effort to understand how technology can be integrated with more confidence in modern society.

  Treating and preventing postpartum depression is related to a number of attitudinal and practical barriers. Addressing these barriers are web-interventions using persuasive technology, aiming to identify women at risk, prevent development of depressive symptoms, and increase subjective well-being. The purpose of this study was to investigate persuasive features and acceptability among users of “Mamma Mia”; a web-intervention for perinatal depression. Based on mixed-model design, semi-structured interviews were conducted on ten perinatal well-educated, employed women with partners (age 28-41). The statements derived from the interviews were unitized and coded into two theoretical and methodological frameworks; SWOT and Persuasive Systems Design (PSD) Model. Results from content and thematic analyses show that the PSD-model and SWOT framework capture significant aspects and qualities of persuasive features in explaining information systems’ interaction with its users. Thematic analysis indicates that the “Mamma Mia” intervention is perceived as acceptable, and professional, which are qualities predicting adherence. The study contributes support for assessing persuasive features to develop successful persuasive systems, utilizing specific persuasive features that predict adherence, and qualities of features to enhance user satisfaction, and effectiveness of mental health interventions.

  Background: Evidence for the efficacy of web-based treatments for depression has increased substantially the last few years. However, many of these programs obtain poor effect sizes or fail to become a part of routine practice. Such issues could be due to a knowledge gap on how these interventions should be implemented. Objective: The primary aim of this study is to examine what is known from the existing literature about implementation of internet interventions for depression. Method: A systematic scoping review of English and Scandinavian-language articles was carried out on 12 databases. Additional papers were identified by contacting relevant societies, as well as hand-searching journals and reference lists. Only empirical studies on internet-based interventions for depression were included. Relevant articles were subjected to a directed content analysis, using May and Finch’s (2009) Normalization Process Theory (NPT) as a theoretical framework to identify implementation information. Results: 7 076 citations were identified and screened for relevance, resulting in 255 full-text articles on internet interventions for depression, of which 51 % were relevant to the implementation framework (N = 130). Content analysis revealed that there was a substantial lack of reporting on implementation. Furthermore, researchers tend to use a non-systematic approach when reporting on implementation and often fail to consider the different organizational levels involved in putting an intervention into practice. Conclusion: The review identified considerable knowledge gaps in the literature. These findings indicate that the field of internet interventions for depression require a great deal of research on implementation, especially in areas that relate to other levels than intervention users.

  Implicit leadership theories have been shown to be potent in the development of global leadership models that accommodate the challenges posed to leadership efforts in a globalized world. Furthermore, the rise of women to leadership positions warrants investigations of whether individuals hold differing implicit leadership theories for men and women. The purpose of this study was to investigate whether implicit leadership theories differ for male and female leaders, and whether the difference was greater in a neutral versus masculine work- context. The present research project utilized a short version of project GLOBE’s leadership questionnaire that was administered to 579 students (311 women and 268 men) at Norwegian universities and University colleges. Observations were analyzed with a GLM repeated measure model in SPSS 22. Results revealed no significant relationship between leaders’ gender and the rated importance of leadership attributes, contrary to the hypothesized expectations. Furthermore, a significant but very small interaction-effect (ηp2 = .015) between leader gender and work-context was found to affect ratings of leader attributes. Methodological limitations as well as theoretical and practical implications of the results are discussed. The present project was initiated and carried out by two master students under supervision by Professor Kjell Ivar Øvergård at the University College of Buskerud and Vestfold (HBV) and Associate Professor Cato Alexander Bjørkli at the University of Oslo (UiO). The investigated data were collected by the students. Furthermore, the data were analyzed by the students with extensive assistance from Professor Øvergård. Separate theses were written since the students attend differing master courses.

  Depression is one of the most frequently diagnosed mental health disorders among adults, and appropriate treatment are not widely accessed. The Internet holds promise as a cost-effective and convenient delivery platform of interventions for depression. However, a common finding in health services is the failure to transfer interventions found effective in research, to routine settings. This finding has called for an emphasis of implementation among scholars. This scoping review aims to investigate the existing literature of implementation of internet interventions for depression, as coded onto the active implementation components. Quantitative and qualitative analyses were used to investigate the amount of knowledge of implementation in the field of internet interventions for depression, and what that knowledge entailed. The results suggested that there exists limited knowledge of implementation of internet interventions and that there is a tendency not to report on implementation-relevant factors in the literature of internet interventions. Overall, the competency drivers have received the most attention, while little to no attention have been placed on the organization and leadership drivers. Furthermore, the qualitative analysis revealed that staff selection was not concerned with the selection of practitioners, rather reflect reporting standards in empirical reports. The results of this scoping review provide implications for future efforts in the successful dissemination internet interventions for depression. Implications and recommendations for future research are discussed.

  The purpose of this study was to identify important aspects of the work at an emergency call centre during large-scale incidents, according to the operators who work there. As communication has been regarded as an important factor in complex situation, this study will also investigate to what extent the work at the call centre can be understood as communication. To determine this, semi-structured interviews have been conducted, asking 14 operators about their work at the emergency call centre. The recorded interviews were transcribed, unitized and coded on a content model and a tool for communication, ISBAR. The content model was developed on the basis of a bottom-up thematic analysis, and consists of 12 sub-themes arranged into six themes. The content model accounted for 93.6% of the total amount of statements, and the remaining 6.4% were irrelevant statements for the work at the call centre during large-scale incidents. Hence, this may imply that the content model still present all the important aspects of the work at the emergency call centre during large-scale incidents according to the operators who work there. ISBAR tool of communication account for 10% of the total amount of statements, which imply that the work at the emergency call centre is complex and consist of several factors in addition to communication. This implies that the work at the call centre during large-scale incidents is more complex than just dealing with communication. This study contributes to understand the work at emergency call centre during large-scale incidents, and elaborate the complexity of this work.

  A key feature of civil safety is the ability to respond to unwanted incidents. The first link in the response chain is usually the emergency call centers, and the purpose of this study was to investigate the work at an emergency call center in connection with large scale incidents. The delivery of the study is two-fold: firstly, a bottom-up analysis was performed in order to outline work at the emergency call center during large scale incidents. This approach resulted in a content model depicting the features of work during large scale incidents. Secondly, a theory driven top-down analysis was performed based on the same data in order to investigate whether a resilience perspective on safety is an appropriate framework for work at the emergency call center during large scale incidents. The data consisted of emergency call center operators’ reflections around their own work during large scale incidents, and was gathered through semi-structured interviews. Statistical comparisons between the resilience model and the content model revealed that the former was not able to account for all the statements captured in the content model, and hence it does not provide a complete framework for understanding work at the emergency call center during large scale incidents. This study provides insight to a field that has received little attention from previous research and contributes to a better understanding of the role emergency call centers play with regard to emergency management and hence to civil safety.

  Emergency response efforts usually involve several teams from different agencies who are working to save lives or property. It is becoming more usual that the commander responsibilities are being performed in a context of multi-agency and multi-jurisdictional response. This paper explores the interdisciplinary collaboration between emergency response leaders. This is done through examining to which extent a practical check-list and a theoretical model of interdisciplinary collaboration were able to account for interview statements from operative leaders in the three emergency units in Norway regarding collaboration Semi-structured interviews were performed with 17 operational leaders with experience from working in Incident Command Post (ICP). Based on a mixed-model approach, the interviews were transformed into quantitative data and analyzed in SPSS. The results revealed that neither the practical frameworks nor the theoretical model were able to account for all the statement. When the two frameworks were combined they accounted for 1516 of the 1649 statements that were identified in this study. The 133 remaining statements were analyzed with the help of a content analysis, which identified 6 new categories. This implies that a framework for collaboration in the emergency response domain cannot be based entirely on the studied models.

  Operational commanders have to collaborate across emergency units and make several time-critical decisions in order to quickly and effectively handle emergency incidents. The purpose of this study was to empirically test whether a domain-specific joint checklist and a theoretical team decision-making model were able to account for reflections shared by operational commanders regarding decision-making in Incident Command Post (ICP). Based on a mixed models design, semi-structured interviews were first conducted with 17 operational commanders from the three emergency units in Oslo and the surrounding districts in south-east Norway. The interviews were then unitized into 1626 statements and coded into categories in the FORSTÅTT checklist (Vigerust, Andersen & Vollebæk, 2009) and the Intuitive team Decision Making (ITD) model (Kline, 2005). The results indicate that neither of these two models could account completely for reflections shared by operational commanders on decision-making in ICP. The two models combined could account for 86.6% of all the statements. A thematic analysis of the statements not captured by either models uncovered six themes relevant to decision-making. An alternative model combining the two models and the residual themes was suggested. This study contributes to an increased understanding of which elements affect the decision-making process in ICP, and has both theoretical and practical implications.

  BACKGROUND: Studies suggest that trained medical personnel deliver manual ventilations at excessive rates while performing advanced cardiac life support (ACLS). We seek to uncover the root causes of hyperventilation during ACLS. HYPOTHESIS: We hypothesized that the presence of socio-emotional stressors would increase the ventilation rate during simulated cardiac arrest in a manikin model. METHOD: A within-subject study involved two conditions presented in randomized order. Ten students at the University of Oslo participated in the study. In the control condition the participants ventilated an intubated manikin while being alone in the room. The other condition involved in addition the presence of six more people and a telephone conversation with a simulated 911 dispatcher. All participants were instructed to ventilate the manikin ten times per minute in both conditions. Ventilation rate was measured by the interval between the initiation of each ventilation (Inter-Response-Interval; IRI). RESULTS: The ventilation rate was higher during exposure to socio-emotional stressors (Mean IRI = 5.55, SD = 2.57) than during the control condition (Mean IRI = 7.28, SD = 2.51; t(9) = -3.205, 95% CI -2.95, -.51; Cohen's d = 1.04; p = .011). Five participants ventilated faster than the recommended rate of 10 bpm during the socio-emotional scenario (range 11.5-22 bpm). Only two persons ventilated faster than the recommended rate of 10 bpm in the control condition. CONCLUSIONS: Socio-emotional pressure increases ventilation rate during advanced cardiac life support in a manikin model. This may have consequences for the organization and training of ACLS providers.

  BACKGROUND: Studies suggest that trained medical personnel deliver manual ventilations at excessive rates while performing advanced cardiac life support (ACLS). Excessive ventilation rates may contribute to increased mortality among these patients. We seek to uncover the root causes of hyperventilation during ACLS. HYPOTHESIS: We hypothesized that the presence of socio-emotional stressors would increase the ventilation rate during simulated cardiac arrest in a manikin model. METHOD: A within-subject study involved two conditions presented in randomized order. Ten students at the University of Oslo participated in the study. In one condition all participants ventilated a standard intubated manikin while being alone in the room. Another condition involved in addition the presence of six more people and a telephone conversation with a simulated 911 dispatcher. All participants were instructed to ventilate the manikin ten times per minute in both conditions. Ventilation rate was measured by the interval between the initiation of each ventilation event (Inter-Response-Interval; IRI). RESULTS: The participants had a higher ventilation rate during exposure to socio-emotional stressors (Mean IRI = 5.55, SD =2.57) than during the alone condition (Mean IRI = 7.28, SD = 2.51; t(9) = –3.205, 95&percnt; CI –2.95, –.51; Cohen’s d = 1.04; p = .011). Five participants ventilated much faster than the recommended rate of 10 bpm during the socio-emotional scenario (range 11.5–22 bpm for these four people). Only two persons ventilated faster than the recommended rate of 10 bpm in the alone condition. CONCLUSIONS: Socio-emotional pressure increases ventilation rate during advanced cardiac life support in a manikin model. This may have consequences for the organization and training of ACLS providers.

  The control situation-framework is being elaborated with respect to the notion of control strategies. Control strategies are the contextually guided adaptation of control behaviours within the constraints set by current control possibilities and control demands. An experimental pursuit sine-wave tracking setup is currently being adapted to test how humans control and adapt to technical systems. This paper presents some of the interim analyses of a recent experiment. General findings are the presence of non-white ‘noise’ in operator behaviour remnant which may be explained by differences in the operators’ control styles. Comments on the modelling of operator control strategies are presented.

  This study reports on the use of Activity Theory as a supportive framework in a design process. Crews on Fast Patrol Boats in the Royal Norwegian Navy were observed during high speed navigation in coastal waters. The unit of analysis was the navigation team of five persons in their work. Activity was regarded as situated actions shaped by tools, objects and constraints. The framework of Activity Theory was used to form a design language that encompassed the aspects relevant to design and navigation. Based on the findings, a prototype of a automated steering system was built. We suggest that in design process, Activity Theory moves the focus from the technical qualities of artefacts towards how artefacts are used as tools to mediate activity.
