What Factors Impact The Effectiveness Of International Non Governmental Organizations (Ingos) In Ethiopia, Ermias Abraham

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1970s Ethiopia has experienced a massive increase of International Non-Governmental Organizations (INGOs) in its territory. The multiplication of these INGOs seems to be the result of the activities of both international donors and governments in Ethiopia. International donors considered INGOs as efficient, flexible or adoptive to the needs of the community and more trustworthy than government agencies in implementing development projects. International donors also believe that the proliferation of INGOs in Ethiopia will stimulate the growth of political democracy and trade liberalization. The government allowed the influx of these INGOs in order to tap the resources they bring …

Estimation Of Travel Time Based On Vehicle-Tracking Models, Anuj Nayyar

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis we study the travel time problem based on the known traffic density model. Using the conservation law, we model the travel time function by a boundary value problem of a non homogeneous linear hyperbolic equation. The equation is transformed into an initial value hyperbolic equation, and the well-posedness of the problem is discussed. The mathematical analysis for both density and travel problems are given. We also derive the analytic solutions for several special cases of traffic density. Numerical schemes are proposed for solving for travel time problem. Several numerical examples are presented and error analysis on the …

An End To End V.M.T Framework With Controlled V.M.T Tax Rate Using Optimal Feedback Control Technique, Pratik Verma

UNLV Theses, Dissertations, Professional Papers, and Capstones

Vehicle Mile Travel (VMT) is a study related to available alternatives for the road

revenue collection system. As per the demand, the existing Gas/Fuel tax based revenue

collection system is not found an appropriate option in the longer run. Due

to existing system constraints like: no eective tax process for vehicles based on alternative

fuel (e.g. electric vehicles), no eective changes in tax due to economical

ination, and more highway expenditure than generated revenue, an alternative revenue

collection mechanism is required. Hence, the objective is to study an alternative

option in detail, which can address the gaps between required revenue …

Can State And Local Revenue And Expenditure Enhance Economic Growth? A Cross-State Panel Study Of Fiscal Activity, Christopher Arthur Clarke

UNLV Theses, Dissertations, Professional Papers, and Capstones

The slow economic recovery since the 2008 financial crisis and Great Recession requires state and local governments to continue to make difficult decisions concerning which taxes to raise and which expenditures to decrease in order to maintain a balanced budget. As expenditures usually raise economic growth and taxes generally hinder it, seeking the optimum combination of tax structures and expenditure options is necessary to encourage prosperity in a state. In this paper I study the effects of various expenditures and revenue combinations on growth in state personal income from 1977-2010 for 49 states and the District of Columbia. I find …

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2010, 51,664 crashes occurred in Nevada. Only about 9% of those crashes occurred in rural areas of the state. However, if only fatal crashes are considered, 41% of those fatal crashes occurred in rural areas. Generally, speed zones are provided in towns along rural highways to reduce speed-related crashes. However, a guideline is necessary for a consistent procedure to setup speed zones throughout the state. The main objectives of this study are to determine factors associated with crashes and to identify the best practices for setting up speed zones in towns along rural highways.
