The purpose of this study is to explore the extent to which teamwork (developed either during an initial training phase or during a subsequent deployment phase) is influenced by the nature of the team’s environment (extreme vs non-extreme) and the extent to which teamwork is one of the explaining mechanisms for team performance.

Data was collected from 60 teams at 2 time-points: training phase in The Netherlands or Germany and deployment phase (in locations such as Afghanistan and Bosnia-Herzegovina).

This study’s results indicate that when teams consider working in extreme environments, they develop higher levels of teamwork as compared to teams expecting to work in non-extreme environments. These differences remain stable also during the deployment phase, such that teams operating in extreme environments will continue to have higher levels of teamwork as compared to teams operating in non-extreme environments.

With this study, the authors contribute to the teamwork quality research stream by empirically studying how teamwork quality develops in unique military contexts such as extreme environments. Studies in such contexts are relatively rare.

This paper focuses on social innovation dynamics in extreme contexts where institutional volatility is deeply rooted and enduring. In other words, the authors focus their discussion on the challenges that social innovators are facing in their endeavor of solving wicked social problems within an extreme institutional environment. This research is guided by the following question: How does an extreme institutional environment influence social innovation processes?

This qualitative research builds on the unique case of the Palestinian non-governmental organization (NGO) sector, a rarely studied context in organizational studies. The authors combine archival sources with 24 semi-structured interviews with Palestinian NGOs.

The authors theorize three barriers that hinder social innovation in such contexts: institutional trap, effectiveness trap and sustainability trap. The authors also theorize five mechanisms through which these barriers influence each other dynamically: mingling, surviving, undermining, binding and reinforcing. Taken together, these barriers and mechanisms shed light on social innovation processes taking place within extreme institutional environments.

The main limitation of this study is the methodological design, based on an extreme single case-study which, on a bunch of features, is quite unique in the world. The authors argue that the results are all the same transferable to other relatively similar contexts.

By theorizing the institutional barriers to social innovation in an extreme institutional context, the research thus sheds light on how social innovation could be sustained and stimulated in Palestine and other contexts that face similar institutional challenges.

From an engaged scholarship perspective, studying Palestine cannot be more relevant than today considering the turmoil in which Palestinians are. The research thus provides a deeper understanding of organizational and institutional dynamics with crucial social repercussions.

The social innovation literature has overemphasized success stories to the detriment of the struggles that hinder social innovations in extreme institutional environments. By focusing on the barriers that social innovators experience in these contexts, the authors provide novel empirical insight. Furthermore, this study enriches the understanding of the institutional dynamics of social innovations by proposing a process model that elucidates how an extreme institutional context can influence social innovations.

This study investigates the mediating role of organizational change capacity (OCC) in the relationship between the perception of extreme contexts and firm product and process innovation, which was not empirically investigated in the literature. In addition, this study explores the moderating role of the perception of extreme contexts-related variables, which were not operationalized in ordinary firms, on the relationship between OCC and firm product and process innovation.

A questionnaire-based research was conducted to test the suggested hypotheses. The data were gathered from 90 firms during the peak period of COVID-19.

This study shows that OCC, which covers contexts, process and learning dimensions, fully mediates the relationship between the perception of extreme contexts and firm product and process innovation. Also, this study discovers that the perception of extreme contexts, including temporal ordering of extremity, the magnitude of consequences, proximity among people and operational deficiencies, positively moderate the relationship between OCC and firm product innovation.

This study has constraints inherited in survey design, primarily sampling and country context.

This study identifies, conceptualizes and operationalizes the term extreme context, conceptually argued for particular organizations/units in ordinary/mundane organization settings so far. In addition, this study extends the current understanding of how the perception of extreme contexts interacts with a firm's capability to increase innovation efforts. Further, this study shows how OCC mediates the relationship between extreme contexts and firm product and process innovation.

The purpose of this paper is to examine emergency medical service (EMS) personnel’s perceptions and experiences of managing underground mining injury incidents.

In total, 13 EMS personnel were interviewed according to a semi-structured interview guide. The interviews were transcribed verbatim and analyzed using qualitative content analysis.

An underground mining environment was described as unfamiliar and unsafe and, with no guidelines for operational actions in an extreme environment, such as underground mines, the EMS personnel were uncertain of their role. They therefore became passive and relied on the rescue service and mining company during a major incident. However, the medical care was not considered to be different from any other prehospital care, although a mining environment would make the situation more difficult and it would take longer for the mine workers to be placed under definitive care.

This study complements earlier studies by examining the EMS personnel’s perceptions and experiences of major incidents.

Disasters are growing in frequency and scale, unmasking the systemic vulnerabilities of modern supply chains and highlighting the need to understand how to respond to such events. In the context of an extreme event such as the COVID-19 pandemic, this research focuses on how networks of organizations leverage their combined resources and capabilities to develop, manufacture and deliver new products outside their traditional markets.

Following a theory elaboration process, the authors build on resource orchestration theory to develop data collection and analysis protocols to support a multi-case study research design. This research investigates four cases of newly formed networks that emerged in four different countries – Colombia, Italy, the United States and the United Kingdom–in response to the COVID-19 pandemic.

These four networks in the investigation share common characteristics in terms of motivation and approach, creating patterns from which theoretical generalizations are developed into a series of propositions regarding the process of network-level resource orchestration under extreme uncertainty.

The research shows how networks and the organizations within them can streamline processes, swiftly build new relationships and develop a balanced risk management approach to extreme uncertainty.

This research contributes to theory by extending the resource orchestration model to a network level and showing how extreme uncertainty can lead to the emergence of networks and alter the motivations and goals of the member organizations, allowing them to be more responsive.

The purpose of this paper is to explore how male and female leaders define effective leadership in an extreme context.

The authors conducted in-depth interviews with leaders working in an extreme context (a matched sample of female and male Majors and Colonels in the Canadian Armed Forces) and analysed military training materials.

In the military, male and female leadership looks much more similar than might be expected. Further, surprisingly this is not occurring because women are leading in more masculine ways, but rather the opposite; men are leading in more feminine ways.

There is a need for organizations to recognize and acknowledge the role of feminine leadership behaviours. This may also give women a better opportunity to succeed in these types of leadership roles.

This study contributes to the leadership literature by furthering our understanding of the boundary conditions for transformational leadership in relation to gender stereotypes, situational strength, and social identity.

This paper aims to present the design and experimental tests of an active circulating cooling system for the Experimental Advanced Superconducting Tokamak in-vessel inspection manipulator, which will help the current manipulator prototype to achieve a full-scale in-vessel high temperature environment compatibility.

The high-temperature effects and heat transfer conditions of the manipulator under in-vessel environment were analyzed. An active circulating cooling system was designed and implemented on the manipulator prototype. A simulative in-vessel inspection task in a high temperature environment of 100°C was carried out to evaluate the performance of the active circulating cooling system.

The proposed active circulating cooling system was proved effective in helping the manipulator prototype to achieve its basic in-vessel inspection capability in a high temperature environment. The active circulating cooling system performance can be further improved considering the cooling structure coefficient differences in different manipulator parts.

For the first time, the active circulating cooling system was implemented and tested on a full-scale of the in-vessel inspection manipulator. The experimental data of the temperature distribution inside the manipulator and the operating status of the circulating system were helpful to evaluate the current active circulating cooling system design and provided effective guidance for improving the overall system performance.

Highly deprived urban contexts, such as informal settlements in the global south, can turn into niches of extreme innovation and sparkle ingenuity out of necessity. But what are the rationales behind the participation of disadvantaged communities in social innovations? Why do they engage in grassroots innovations? What is it that makes these grassroots try novelties and continue experimenting with them, even when the perceived benefits are not clear yet? This paper aims to examine and conceptualize the rationales for engaging in grassroots financial innovations in the context of extremely deprived urban settings.

This paper is based on the case of grassroots organizations which have started experimenting with the development of a community currency in Kisumu, Kenya. This paper is informed by in-depth interviews with members of three grassroots organizations involved in the community currency, together with observations and meeting participation since 2019.

The rationales argued by the participants for engaging in this grassroots innovation are framed in various ways: as a means for seeking poverty alleviation (the development framing); as a challenge to conventional imaginaries of innovations (the digital framing); and as an innovation embedded in community and trust relations (the community framing). These framings have a mobilizing effect that initially draws participants into the innovation. Yet, what explains persistent participation despite the decreasing influence of these framings over time is the organizational space and strategies of incompleteness accommodating these experiments.

This paper contributes to the emerging body of grassroots innovations movements literature. While research has progressed in its understandings of the challenges of scaling up innovative practices, the examination of the grassroots initiatives stemming from extremely deprived settings, and the rationales and framings behind, have been under examined. This paper comes to bridge this gap.

The purpose of this paper is to report the results of a recent project of complex tests on the survival of structural health monitoring (SHM) technology with piezo wafer active sensors (PWAS) and electromechanical impedance spectroscopy (EMIS) at simulating the concomitant action of harsh conditions of outer space: extreme temperatures, radiations, vacuum.

The tests were conducted on PWAS, consists in adhesive and aluminium discs as structural specimens, with PWAS bonded on them. The substantiating of PWAS-EMIS-based SHM technique consists the fact that real part of the PWAS electromechanical impedance spectrum follows with fidelity the resonance behaviour of the structure vibrating under the PWAS excitation. This EMIS signature is very sensitive to any structural changes and, on this basis, can be monitored the onset and progress of structural damages such as fatigue, cracks, corrosion, etc.

The conclusion of the tests is that the cumulative impact of severe conditions of temperature, radiation and vacuum has not generated decommissioning of sensors or adhesive, which would have meant the compromise of the methodology. A second important outcome is linked to the capability of this methodology to distinguish between the damages of mechanical origin and the false ones, caused by environmental conditions, which are, basically, harmless.

The question of transfer of PWAS-EMIS-based SHM technology to space vehicles and applications received, as a novelty, a first and encouraging response.

The purpose of this paper is to enable autonomous door-opening with unknown geometrical constraints. Door-opening is a common action needed for mobile manipulators to perform rescue operation. However, it remains difficult for them to handle it in real rescue environments. The major difficulties of rescue manipulation involve contradiction between unknown geometrical constraints and limited sensors because of extreme physical constraints.

A method for estimating the unknown door geometrical parameters using coordinate transformation of the end-effector with visual teleoperation assists is proposed. A trajectory planning algorithm is developed using geometrical parameters from the proposed method.

The relevant experiments are also conducted using a manipulator suited to extreme physical constraints to open a real door with a locked latch and unknown geometrical parameters, which demonstrates the validity and efficiency of the proposed approach.

This is a novel method for estimating the unknown door geometrical parameters with coordinate transformation of the end-effector through visual teleoperation assists.
