Organizations working in high-hazard environments contribute significantly to modern society and the economy, not only for the valuable resources they hold but also for the indispensable products and services they provide, such as power generation, transportation and defense weapons. Therefore, the main purpose of this study is to develop a framework that outlines future research on systems safety and provides a better understanding of how organizations can effectively manage hazard events.

In this research, we developed the high hazard theory (HHT) and a theoretical framework based on the grounded theory method (GTM) and the integration of three established theoretical perspectives: normal accident theory (NAT), high reliability theory (HRT) and resilience engineering (RE) theory.

We focused on the temporal aspect of accidents to create a timeline showing the progression of hazard events and the factors contributing to safety and hazards in organizations. Given the limitations of the previous theories in providing a coherent explanation of hazard event escalation in high-hazard organizations (HHOs), we argue that the highlighted theories can be more complementary than contradictory regarding their standpoints on disasters and accident prevention.

A proper appreciation of the hazard nature of organizations can help reduce their susceptibility to failure, prevent outages and breakdowns of systems, identify areas for improvement and develop strategies to enhance performance.

By developing HHT, we contribute to systems safety research by developing a new, refined theory and enrich the theoretical debate. We also expand the understanding of scholars and practitioners about the characteristics of organizations working in high-hazard environments.

The motivation to participate in crowdsourcing (CS) platforms is an emerging challenge. Although researchers and practitioners have focused on crowd motivation in the past, the results obtained through such practices have not been satisfactory. Researchers have left unexplored research areas related to CS pillars, such as the evolution of the crowd’s primary motivations, seekers applying effective policies and incentives, platform design challenges and addressing task complexity using the synchronicity of the crowd. Researchers are now more inclined to address these issues by focusing on sustaining the crowd’s motivation; however, sustaining the crowd’s motivation has many challenges.

To fill this gap, this study conducted a systematic literature review (SLR) to investigate and map the challenges and factors affecting sustained motivation during CS with the overcoming implications. Studies that satisfied the inclusion criteria were published between 2010 and 2021.

Important sustainable factors are extracted using the grounded theory that has sustained participation and the factors' cohesion leads to the identification of challenges that the pillars of CS face. Crowds being the most vital part of CS contests face the challenge of engagement. The results reported the factors that affect the crowd’s primary and post-intentions, perceived value of incentives and social and communal interaction. Seekers face the challenge of knowledge and understanding; the results identify the reason behind the crowd’s demotivation and the impact of theories and factors on the crowd's psychological needs which helped in sustaining participation. Similarly, the platforms face the challenge of being successful and demanding, the results identify the latest technologies, designs and features that seekers proclaim and need the platforms designer's attention. The identified task challenges are completion and achievement; the authors have identified the impact of trait of task and solving mechanisms that have sustained participation.

The study identifies, explores and summarizes the challenges on CS pillars researchers are facing now to sustain contributions by keeping participants motivated during online campaigns. Similarly, the study highlights the implication to overcome the challenges by identifying and prioritizing the areas concerning sustainability through the adoption of innovative methods or policies that can guarantee sustained participation.

COVID-19 has profoundly shaped human interactions, and, within public healthcare systems, care relations. Through the lens of social suffering, this study explores how employee innovation is shaped by the pandemic crisis and different managerial approaches in the context of public geriatric care in Northeast Italy.

This study adopts a qualitative methodology. A total of 29 semi-structured, open-ended interviews were conducted with 23 healthcare professionals involved in geriatric care, with managerial and without managerial positions. Observation was integrated as auxiliary research to further capture on an operational level the interactions among the actors involved.

The COVID-19 crisis significantly shaped employee innovation for healthcare professionals, as the suffering it provoked in the system motivated and urged them to engage in innovative initiatives. Where employees’ engagement in innovation was recognized by the management, it was found that the suffering was mitigated, and creativity and solidarity emerged in the innovation process. Where top-down approaches did not recognize employees’ efforts and innovative initiatives, need-driven innovation and greater tensions came forward, enhancing the overall suffering in care relations and resulting in some employees considering leaving their profession.

This study is based on a single case study.

This study further highlights the employee participation in innovation as a crucial practical implication for sustaining the quality of public care and assistance. A practical implication emerging from this study suggests that “ordinary” healthcare professionals’ engagement in innovative initiatives and in their operationalization should be encouraged by the organization. In a system as complex as the public healthcare one, valuing the bottom-up, clinical inputs appears fundamental if innovation is to move away from mere technological adaptation to embrace a more comprehensive process, involving the professionals who are engaging in innovative endeavors. From a managerial point of view, adopting an approach that recognizes, supports and provides coordination to employee innovation seems instrumental to nurture an environment where employee voices feel heard, and creativity, solidarity and overall positive collaboration can occur. Thus, another significant practical implication includes the retention of healthcare professionals in the public sector in times of crisis.

With the outbreak of the COVID-19 pandemic, the necessity to explore the “human side” of innovation and its connection to emerging human needs during a crisis is growing. This study focuses on employee participation in innovation processes due to COVID-19, thus contributing to the employee-driven innovation (EDI) literature. Through the lens of social suffering, it scrutinizes the interactions between bottom-up perceptions and responses and top-down strategies in a public healthcare setting. Hence, this study addresses two major gaps present in EDI literature, for the most part focused on the private sector and on the managerial structures, tools and interventions.

Prior research suggests that collaboration is key to sustainable community development and environmental management, and peer-to-peer learning (P2PL) may facilitate community building and collaborative learning skills. This study aims to examine the effect of P2PL on the enhancement of environmental management and sustainable development skills, community building and social capital (i.e. connectedness) and understanding of course learning objectives.

Quantitative and qualitative longitudinal survey data was collected in a sustainable development focused course offered at a large American public university that uses P2PL to explicitly facilitate community building and collaborative skills. Safety precautions and changing locational course offerings due to the COVID-19 pandemic in years 2020, 2021 and 2022 provided an opportunity to evaluate the impact of P2PL on these skills during both virtual and in-person formats. Additionally, this study compared in-course student evaluations with students taking other sustainable development-related courses with collaborative learning aspects to understand the wider effectiveness of this course structure.

This study finds that course format (virtual vs in-person) overall made no difference in either connectedness or conceptual understandings, and that students in both formats felt more connected to others than students taking other courses with P2PL. Scaffolding P2PL and supplemental peer support can yield improved connectedness and learning among students taking environmental coursework.

Sustainable development requires group collaboration and partnership building skills. Issues are consistently raised about the challenges to teaching these skills in higher education. The students and instructors in this research study identify P2PL strategies to address these challenges for in-person and virtual classroom settings.
