Search And Rescue Missions On The Rise In U.S. National Parks, Sahalie Donaldson

Capstones

Across the country the number of search and rescue missions in national parks has been creeping up since 2018. While the number of missions being undertaken are up overall, some parks in particular have seen a dramatic spike in the number of people requiring rescue services, straining a patchwork, often volunteer-based search-and-rescue system. Some parks like Maine’s Acadia National Park, Zion National Park in Utah and the Grand Canyon National Park even experienced their busiest years to date in regards to the number of search and rescue calls they received.

Both former and current park rangers who go on search …

Nature-Based Solutions In Environmental Planning: Ecosystem-Based Adaptations, Green Infrastructures, And Ecosystem Services To Promote Diversity In Urban Landscapes, Lorena Alves Carvalho Nascimento

Dissertations and Theses

Nature-based solutions encompass strategies that explore ecosystem-based adaptations, green infrastructures, and ecosystem services in environmental planning and landscape management. However, nature-based solutions do not always consider ecological values and perspectives from Black, Indigenous, and Global South population. This dissertation has three independent papers that explore the application of ecosystem-based adaptations, green infrastructures, and ecosystem services in communities unheard by environmental planning agencies. The first paper is a conceptual framework that used literature review and observations of current human-nature interactions to reflect how the criminalization, acculturation, and cultural appropriation of cultural ecosystem services have burdened Black and Indigenous identities. Recommendations for …

Employees' Expectations Of Leadership Development Programs And Their Effects On Anticipated Voluntary Employee Turnover And Organizational Commitment, Candace Johnson

Dissertations

Employee retention and commitment have gained attention over the past years (Mutsuddi, 2016). Commitment is the link that connects an individual to their organization, thereby decreases the probability of turnover (Allen & Meyer, 1990; Hague et al., 2019). According to Mutsuddi (2016), decreasing employee turnover remains a critical element for sustainment in any organization. However, most organizations invest in policies and practices to increase employee commitment; those same practices can lead to employee turnover (Mutsuddi, 2016). This study explores the effects of leadership development programs and their impact on organizational commitment and anticipated voluntary employee turnover. A qualitative research design …

Barriers And Facilitators Of Nonprofit Community Involvement, Claire Galvin

School of Professional and Continuing Studies Nonprofit Studies Capstone Projects

Community-facing organizations have recently been critiqued for catering to donors instead of prioritizing community involvement. This lack of community engagement can lead to organizations not being as effective at the work they aim to do within these communities. Studies also show that organizations that have a more equal distribution of power engage more with their communities. This research project investigated how power distribution in Richmond- area nonprofits impacted the way that their communities were involved within their organizations. Findings from this study suggest that nonprofit fundraisers are more invested in creating community representation within their organization rather than cultivating a …

Who Mediates Matters: The Impact Of Individual Mediator Competency Skills On Individual And Civil Conflict Mediation, Erin V. Rowland

Doctoral Dissertations

Until this point, research in the field of conflict mediation concerning how third-party entities impact mediation outcomes has largely focused on the macrolevel factors of those entities and the disputing parties – geographic proximity of the mediating states to the disputants, the presence of alliances, the existence of enduring rivalries, etc. However, even when macrolevel factors are relatively similar, differences still exist in mediation outcome. This research proposes that some differences in mediation outcome are due to the impact of individual mediator factors, more specifically individual mediator competency skills in the form of Knowledge, Know-how, and Behavioral competencies. Borrowing from …

Racing The Machine: Automation-Induced Inequality Through The Lens Of The Fourth Industrial Revolution, Evelyn Martin

Economics Theses

This paper analyzes the scope and velocity of automation-induced inequality as a result of the Fourth Industrial Revolution. We find that, when left unchecked by intentional government policy, the direct impacts of inequality will affect virtually all demographic groups and occupational skill levels, as well as, be hastened by future recessions and noticeable skill biases. We find that unconditional cash transfers in the form of a universal basic income have the potential to address the aforementioned scope and velocity due to their cash transfer modality and universal qualities. As we are living through the start of the Fourth Industrial Revolution, …

Collateral Damage: How Expanding Public Charge Policy Influences Adult Esl Enrollment, Allison M. Eckert

Master's Theses

This study used statistical analysis of enrollment records for ESL programs at community colleges throughout California from 2015-2019 to determine whether adult immigrants’ participation in public ESL programs was reduced under President Donald Trump. Immigrant families’ lesser use of public education services and means-tested federal benefits has been widely documented in the wake of Trump’s expansion of the public charge rule, which counted immigrants’ use of a wider array of public benefits against their case for residency in the United States than had any previous iteration of the rule. Failing the public charge test can block an immigrant’s entry into …

The Implementation Of Tribal Provisions From The Vawa 2013 Reauthorization, Deejay E. Chino

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recent changes in VAWA allows tribes – for the first time – to prosecute non-Indians for intimate partner violence. In order to do so, however, tribes have to first meet specific federal mandates. Implementation of federal regulatory policy by American Indian tribes is a dynamic and complex process but there is a dearth of information on the challenges tribes face or on factors that would facilitate successful implementation at the tribal level. This legislation has filled a serious gap in tribal jurisprudence but not all tribes are able to meet requirements, which include having specific legal codes and justice resources. …

Improving Pedestrian Safety With The Implementation Of The Demand-Responsive Transverse Rumble Strip As A New Traffic Safety Countermeasure, Md Shakhawat Hossen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The traditional TRS has been extensively used as a traffic calming device to provide cognitive alerts in the form of sound and vibration to drivers. However, TRS always remains fixed on the road and thus exerts cognitive alerts, irrespective of any potential downstream hazards. Moreover, the continuous exposure to rumble strips has been identified as a source of discomfort and annoyance for drivers, which limits its application to potentially useful scenarios. This study explores a rumble strip design with dynamic behavior named as Demand-Responsive Transverse Rumble Strip (DRTRS) in order to address the limitations of static TRS. The study incorporates …

Factors Influencing The Usage Of Shared E-Scooters : A Case Study Of Chicago, Farzana Mehzabin Tuli

Graduate Theses and Dissertations

The rapid popularity growth of shared e-scooters creates the necessity of understanding the determinants of shared e-scooter usage. This thesis estimates the impacts of temporal variables (weather data, weekday/weekend, and gasoline prices) and time-invariant variables (socio-demographic, built environment, and neighborhood characteristics) on the shared e-scooter demand by using four months (June 2019- October 2019) period of data from the shared e-scooter pilot program in Chicago. The study employs a random-effects negative binomial (RENB) model that effectively models shared e-scooter trip origin and destination count data with over-dispersion while capturing serial autocorrelation in the data. Results of temporal variables indicate that …

Level Of Service For Parking Facilities Based On Search Time, Fernie Briones

Open Access Theses & Dissertations

Level of Service (LOS) is a term used by transportation engineers to identify the quality of service of transportation facilities to the public. The Highway Capacity Manual has yet to provide guidance on LOS analysis for parking facilities. Parking search time has been proposed by several researchers as the indicator for the LOS criteria for parking facilities. This thesis investigated the use of search time for LOS analysis for on street and off-street parking facilities. The analysis of LOS for off-street parking focused on the measurement of parking search time. Three search time measurement methods have been proposed: the license …

Determination Of Faculty And Staff Parking Permit Prices On University Campuses, Rodrigo Garcia

Open Access Theses & Dissertations

University campuses are the origins and destinations of a variety of trips generated by faculty, staff, students, and visitors. The vast number of trips that are attracted to university campuses result in parking congestion issues. In order to manage campus parking demand, universities establish Transportation and Parking Offices (TPO). This research has developed a two-stage procedure that can be used by TPOs as a tool for determining faculty and staff parking permit prices on university campuses. The first stage of the procedure is the determination of a single campus-wide base price (which may be regarded as the reference price or …

“You Can’T Hide Behind Being A House”: Examining The Policy Process, Design, And Implementation Of Short-Term Rental Regulations, A Case Study Of Nashville, Tn, Jamie L. Cathey

All Dissertations

Following the economic crash of 2008, the rapid expansion of platform capitalism and the recruitment of others to work for themselves using a company’s platform, has led to a ‘paradigm shift’ in which a sharing economy business model has enabled small entrepreneurial endeavors to become industry giants (Srnricek, 2017). One such platform, Airbnb, has created a new, informal tourism accommodation sector that is bringing with it questions of regulation and community impact. Airbnb regulation thus is a growing national and international trend affecting cities of all sizes and forcing policy response and change at the local government level. Current trends …

Human Capital In The Knowledge Economy : A 3-Country Case Study In Healthcare, James Scott Mccallum

Theses and Dissertations

During the present knowledge economy there appear to be labor shortages at the same time and in the same regions in which there is an excess of labor supply. Such a pattern would run counter to previous major economic disruptions, as well as questioning traditional free market economic theory of supply and demand principles. Implications for policy where there are global labor shortages along with surplus labor availability in a market economy, are significant. It will likely indicate a drag on economic growth for business sectors, for regions and perhaps globally. It would indicate an accompanying growing disparity of income. …
