Leaders’ Responsiveness To Creating Ethical Climate For Whistleblowing And Implicit Retaliation In The Public Sector, Oluwatoyin Olusegun

Walden Dissertations and Doctoral Studies

Whistleblowing is reporting unethical or illegitimate practices witnessed by a member of an organization. Despite the laws and policies protecting whistleblowers in the public sector, many employees who report observed wrongdoings face retaliation. Creating an ethical climate impacts the responsiveness of organizational leaders to whistleblowing, yet little is known about how middle-level managers navigate organizational factors, situational factors, and personal beliefs to create an ethical climate. The current study aimed to bridge the knowledge gap by exploring how middle-level managers in government organizations in California described how organizational and personal factors influence their ability to create an ethical climate that …

Readability And Suitability Of Local Disaster Preparedness Materials In Predominantly Hispanic Border Communities: A Case Study Of Cameron County, Texas, Katarzyna Sepielak, Dawid K. Wladyka

Sociology Faculty Publications

Community awareness is a key component of disaster resilience and numerous agencies developed a plethora of preparedness materials. Previous studies evaluated national-level resources and social media content indicating that these efforts are not effectively reaching vulnerable populations, as the information is provided at or above the secondary education level. However, the local-specific content has been mostly overlooked in the analyses, subsequently neglecting the needs of areas with specific demographics and hazards, like predominantly Hispanic border communities. Thus, this study turns to local preparedness and mitigation materials, rather than general internet searches or national level documents. We analyze information provided on …

Adopt: An Environmentally-Friendly System For Alerting Drivers To Occluded Pedestrians Traffic, Abrar Abdulrahman Alali

Computer Science Theses & Dissertations

The emergence of sensing technologies and vehicular communications has brought significant opportunities for enhancing pedestrian safety on city streets. However, existing solutions rely on costly technologies such as computer vision and trajectory prediction to detect crossing pedestrians, while they have limits in detecting pedestrians who are occluded by parked cars. Despite the presence of collaborative perception by surrounding vehicles and infrastructure, there is a notable absence of incorporating existing parked cars themselves due to their insufficiency in detecting pedestrians and communicating with other cars while they are turned off. Furthermore, accommodating pedestrians on streets has been linked to an additional …

Private Management Of African Protected Areas Improves Wildlife And Tourism Outcomes But With Security Concerns In Conflict Regions, Sean Denny, Gabriel Englander, Patrick Hunnicutt

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Protected areas can conserve wildlife and benefit people when managed effectively. African governments increasingly delegate the management of protected areas to private, nongovernmental organizations, hoping that private organizations’ significant resources and technical capacities actualize protected areas’ potential. Does private sector management improve outcomes compared to a counterfactual of government management? We leverage the transfer of management authority from governments to African Parks (AP)—the largest private manager of protected areas in Africa—to show that private management significantly improves wildlife outcomes via reduced elephant poaching and increased bird abundances. Our results also suggest that AP’s management augments tourism, while the effect on …

Criticizing The Asset Repatriation Policy For Tax Amnesty In Indonesia: An Interpretive And Comparative Study, Nidya Hapsari

Jurnal Vokasi Indonesia

Indonesia finds tax amnesty as a reliable funding alternative to develop a sustainable economy. Since 1964, Indonesia has implemented five tax amnesty programs. The latest two programs would offer lower amnesty compensation rates if taxpayers repatriated offshore assets back to Indonesia. However, the tax amnesty repatriation policy merely contributed minimal amounts of repatriated assets and low number of participants. Consequently, it failed to raise sufficient liquidity, fiscal revenues, tax compliance and economic growth. Hence, the study aims to (1) determine the justification and mechanism for the asset repatriation policy and (2) criticize the repatriation policy implementation. Applying interpretive and comparative …

A Comparative Review Of Soil Carbon Sequestration Methods In Brazil’S Agriculture, Skylar Cheng

Discussions

Brazil is under unique pressure to adopt sustainable agricultural practices due to its intricate biodiversity and globally dominant agricultural sector. Increasing soil degradation, agricultural land expansion, and rising levels of atmospheric carbon are nationwide concerns that require multifaceted solutions. Integrated agricultural systems, which rehabilitate soils through crop, forage, and livestock rotation as well as biochar—a carbon-rich soil amendment—can address such concerns. These sustainable farming practices improve carbon sequestration and soil fertility; however, uptake remains minimal due to environmental, economic, and policy barriers. Accordingly, this paper proposes a comprehensive model of integrated systems and biochar, in which the benefits of one …

Don’T Get Lost In The Numbers: An Analytic Framework For Nuclear Force Requirements Debates, Patrick Mckenna, Dylan Land

Joint Force Quarterly

This article proposes an approach to nuclear force sizing debates based on a framework built on four analytic dimensions: overarching risk management approaches; deterrence and assurance objectives; strategic force employment guidance; and operational constraints. The answers to key questions across these dimensions provide a structure to inform debates about the appropriate size and characteristics of U.S. nuclear forces. Only after clarifying U.S. objectives across these dimensions and focusing on key considerations therein should policymakers enter nuclear force sizing debates. The resulting analysis does not advocate for any policy position or hypothesize the “correct” number of nuclear forces. Instead, the purpose …

Preventing The Nuclear Jungle: Extended Deterrence, Assurance, And Nonproliferation, Jennifer Bradley

Joint Force Quarterly

Today, most people do not remember a time when the United States was not allied with the North Atlantic Treaty Organization (NATO), Australia, Japan, and the Republic of Korea. As these alliances span over seven decades, it is easy to take for granted that the relationships will continue as they always have into the future. The changing security landscape and the emergence of the two-peer nuclear environment will challenge extended deterrence in ways not yet well understood. This requires reexamining deterrence strategies and potentially acquiring new capabilities to effectively assure allies and close the growing “assurance gap.”

An Interview With Anthony J. Cotton, William T. Eliason

Joint Force Quarterly

Our threats are not isolated to one command or nation. These global challenges require a concerted effort to strengthen not only deterrence but also partnerships with our allies and partners. For the first time, the United States faces two major nuclear powers that could operate at any level or domain of conflict to meet their national objectives. We are now in a multipolar world with potential adversaries that could threaten the United States, our allies, and our partners with nuclear weapons and nonnuclear capabilities that could have devastating impacts.
