Abstract

As the frequency and severity of disasters continue to increase, the need for collaboration amongst all humanitarian stakeholders in humanitarian supply chain activities during all aspects of the disaster cycle has become more critical to the success of relief operations. Humanitarian non-governmental organizations (NGOs) are voluntary organizations operating in highly dynamic and chaotic environments to provide aid to people in need. But as the impact of disaster increases and the funding becomes more limited and competitive, they face mounting pressures from stakeholders to improve the quality of their operations. Similarly, private organizations are also under higher levels of scrutiny to become more socially responsible. In response, literature has turned to service operations and corporate social responsibility research, focusing on customer service and integration improvements as a path toward more effective disaster relief outcomes. Therefore, this dissertation aims to build upon this humanitarian service research stream. This dissertation examines how the humanitarian supply chain's operational characteristics affect the workforce and community integrative behaviors, operational activities in the wake of disasters, and collaborative efforts between relief actors. Essay 1 employs approach-avoidance theory to examine the effects of trauma exposure on aid worker behaviors and supply chain integration activities. It also examines the moderating effects of various forms of supervisor support. Utilizing a scenario-based vignette experiment, results indicate that trauma exposure induces both approach and avoidance behaviors. As such, it simultaneously hinders cooperative commitment and improves organizational commitment among aid workers. Furthermore, we find that supervisor support strengthens these relationships. As such, this study contributes to disaster management, integration, and leadership literature streams. It highlights environmental mechanisms to aid worker integrative behaviors and provides decision-making guidance to NGOs regarding where to direct support investments. Essay 2 combines religion with volunteer management. It employs both social capital and person-organization fit theory to examine the effects of NGO religiousness and volunteer religious fit, on volunteer behaviors and operational performance. Utilizing two scenario-based video experiments, results indicate that NGO religiousness lessens social capital, negatively impacting volunteer behaviors and operational performance. Conversely, when NGOs and volunteers experience religious fit, it helps to minimize the negative effects of NGO religiousness and improve their operational performance. As such, this study contributes to the Humanitarian Operations literature by advising strategy around religious alignment and volunteer behaviors, retention, and operational performance. Essay 3 focuses on the vital role of private organizations in disaster relief and the importance of private-NGO collaboration. Employing resource dependence and matching theory, it examines mechanisms of private organization attitudes toward private-NGO partnerships. It also examines how the influence of these mechanisms may differ across disaster relief stages. Utilizing a scenario-based vignette experiment, results indicate that NGO resource capabilities motivate private organizations and their willingness to engage in private-NGO partnerships. As such, this study contributes to the private-NGO partnership literature and informs NGOs’ strategy around private organization motivations, decision-making, and alliance formation. This dissertation produces insights across the humanitarian supply chain, informing important curiosities involving NGOs, private organizations, aid workers, and the customers/communities they serve.
