Interdisciplinarity among Academic Scientists: Individual and Organizational Factors

Xiao, Fang 01 May 2014 (has links)
Drawing on a wide variety of social science theories, this study investigates the effects of tenure system, university climate for interdisciplinary research (IDR), gender, and industry experience on academic scientists’ engagement in IDR in different disciplines. Using survey and bibliometric data, two dependent variables are generated to measure production aspects of IDR: the self-reported percentage of IDR papers which is from researchers’ own estimate of their IDR papers responding to one survey question, and the calculated percentage of IDR papers which is a combination of two bibliometric indicators of scientists’ borrowing and boundary crossing activities. Results find that our conventional wisdom about the effects of some individual and organizational factors on scientists’ propensity to engage in IDR is outdated, and their effects depend on the disciplinary contexts. These findings suggest science policy makers, funding agencies and university administrators to keep fresh and informed about scientists’ research activities and underlying context and take full into account of distinct characteristics of different disciplines when they make or reform policies to encourage IDR work.

Is Targeted Testing and Treatment for Latent Tuberculosis Infection Cost-effective? The Experience of Tennessee

Ferroussier-Davis, Odile 09 May 2014 (has links)
Preventative interventions often demand that resources be consumed in the present in exchange for future benefits. Cost-effectiveness analysis is a tool to understand these trade-offs, and inform decision-making under resource constraints. Targeted testing and treatment (TTT) for latent tuberculosis infection (LTBI) consists in identifying people at high risk for LTBI for preventive treatment to decrease the risk of active tuberculosis disease (ATBD). The state of Tennessee began conducting TTT statewide in 2001. This study uses a decision tree to evaluate the cost and outcomes of TTT for LTBI in Tennessee, compared to passive ATBD case finding (PACF). Key probabilities were obtained from the Tennessee TTT program and the literature. Outcomes are measured in terms of Quality Adjusted Life Years (QALY). The cost-effectiveness threshold was $100,000/QALY saved. One-way sensitivity analyses around factors related to study design, the program’s environment, and program performance were conducted, as was probabilistic sensitivity analysis (PSA) which takes into account the uncertainty in multiple parameters simultaneously. The base case, with a 25-year analytic horizon and 3% discount rate, shows that TTT prevents 47 ATBD cases, and saves 31 QALYs per 100,000 patients screened at a societal cost of $12,579 per QALY saved. Sensitivity analyses identified value thresholds that would trigger a change in preferred policy. PSA shows that the likelihood that TTT would be cost-effective is low. Decision makers should carefully assess the characteristics of the local TB epidemic and expected program performance to determine whether TTT is preferable over PACF from a cost-effectiveness viewpoint.

Performance Management System Design and Implementation in Police Agencies: Is Following Recommended Practices Worth It?

Pasha, Obed 09 July 2014 (has links)
As interest in and concerns about performance management systems continue to grow, scholars have increasingly suggested methods to better design and implement these systems in the public sector organizations, with the underlying assumption that they will help public organizations perform better. These suggestions include approaches to design and implement performance management activities, including target selection, indicator adoption, data collection and analysis, and reporting of results. These recommendations are available in the form of books and research articles that cover a wide variety of performance management systems and their respective usage settings. Scholars argue that by using their recommendations (termed as “recommended practices” from here onwards) in designing and implementing performance management systems, system designers and managers can improve organizational performance; a claim I intend to examine in this paper. There are scores of recommended practices spread out in the literature, which not only lack theoretical foundations, but also might be contradictory to each other. The results from this study suggest do not suggest a link between the recommended practices and police performance, as only the practices of using performance information and providing discretion to officers were found to be supporting the hypotheses for only one out of the eight crime categories. These two significant results might be attributed to chance alone. The results, hence, raise questions about the effectiveness of the recommended practices in improving organizational performance. Justification of the use of recommended practices, however, can still be traced to goal-setting theory.

Assessing the Prevalence, Participants, and Predictors of Coproduction: The Case of Atlanta, Georgia

Uzochukwu, Kelechi 17 December 2014 (has links)
In municipalities across the globe, traditional forms of governance are being supplemented by collaborative arrangements between governments and their constituencies toward jointly produced public services. Since the late 1970s, this phenomenon known as coproduction has been utilized in efforts to survive severe budget cuts, improve performance, increase accountability, and welcome traditionally silenced voices. However, no study to date has undergone a citywide assessment of coproduction to determine its breadth and depth in a city. Additionally, there is practically no empirical study that examines what citizen characteristics and perceptions are associated with participation in coproduction. The present study represents a first attempt to begin to fill these gaps in the literature. Specifically, this dissertation analyses: (1) How prevalent is coproduction? (2) Who engages in coproduction? and (3)What motivates coproducers? I employ a mixed-method case study of Atlanta, Georgia via its Neighborhood Planning Unit system, using focus groups, citizen questionnaires, census and GIS data, and direct observations. Overall, the coproduction classifications developed in this dissertation enable more systematic research on coproduction. The dissertation findings also contribute to our understanding of (1) how much this service delivery strategy is being utilized in an urban municipality, (2) which forms are most utilized, (3) what triggers participation in each form, and (4) who utilizes coproduction the most – even challenging the longstanding perception that African Americans and low-income groups do not participate in such activities. Lastly, study findings suggest a need to reconceptualize the current theory of coproduction as a public service delivery strategy.

Nonprofit and Foundation Behavior in Competitive Markets for Grants

Faulk, Lewis H. 11 August 2011 (has links)
This dissertation analyzes competition for foundation grants in the nonprofit sector. First, I examine how inter-organization competition and foundation activity in local grants markets affect organization behavior through institutional pressure on (1) firm fundraising expenses, (2) program expense ratios, and (3) revenue diversification. Second, I explore the impacts of nonprofit program expense ratios and fundraising expenses on foundation grantmaking. This analysis focuses on the relative "prices" of donations to competing nonprofit organizations, represented by these expense ratios, and the impact prices have on foundation grant decisions relative to the impact that nonprofit marketing has. Finally, I examine whether greater competition in grants markets increases the importance of program expense ratios and firm marketing behavior for grant selection. Overall, this dissertation contributes to our understanding of organization behavior and foundation influence in grant-seeking markets and competition's role in the distribution of charitable grants.

Three Essays on the Formation and Finance of Local Governments

Brien, Spencer T. 06 January 2012 (has links)
This dissertation follows a three-essay format. Each essay evaluates a different fiscal institution from a public administration perspective. In the first essay I examine whether state-funded property tax exemptions are effective in reducing the property taxes. This class of exemption is characterized by a grant from state to local governments that is intended to replace property tax revenue and lower property tax payments. Two separate theories of local fiscal behavior predict that that price effects and fiscal illusion will reduce the effectiveness of this type of tax relief. I test these predictions using panel regression analysis on county-level data from Georgia. I find that only two thirds of the revenue allocated to this program is actually used for tax relief. In the second essay I test a model of the property tax in which the levy is set to balance the difference between budgeted expenditures and expected receipts from all other revenue sources. This model demonstrates how the property tax can be used to offset unexpected changes to other revenues given a change in personal income. This model is contrasted with an alternative model in which expenditures are budgeted after expected total revenues have been determined. I will estimate both models for local governments in Georgia and test which more accurately describes local fiscal performance. I will also use both to predict changes to the property tax over a period of time and measure which model generated the more accurate forecast. Unlike the first two papers, which are quantitative analyses of fiscal data, this chapter is a case study of the contract city model of governance as implemented in the newly incorporated city of Sandy Springs, Georgia. I investigate whether the scope of outsourcing in contract cities creates additional challenges for city officials that manage contractor performance. I evaluate the incentive structures in the contract agreements that influence the principal-agent relationship using a textual analysis research method. I find that certain combinations of municipal functions in a single public-private partnership creates the potential for negative synergies to arise which would increase the difficulty of monitoring and managing the private partner.

Growing an Industrial Cluster?: Movie Production Incentives and State Film Industries

Kolenda, Richard S 08 August 2017 (has links)
After witnessing the success of Canadian strategies to attract U.S. film production in the 1990s, states and localities began offering financial incentives in an effort to lure film and video production away from their traditional hubs in California and New York (Christopherson & Rightor, 2010). This effort increased dramatically in the 2000s, both in scope and in scale. Production activity can now locate in states offering rebates of up to 40 percent of costs, even if this exceeds their actual tax bills, and all but a handful of states offer some form of tax incentives (Christopherson & Rightor, 2010; Katz & Rosenthal, 2006; National Conference of State Legislatures, 2011; Vock, 2008). While some states may be reducing incentive packages in the current climate of fiscal austerity, others are doubling down on that strategy as an effort to stimulate job growth and increased economic activity. And while most states tout many successes from these programs in both metrics, the question of whether such policies promote long-term sustainable economic development has not been fully answered. First I use theoretical literature to construct a model of sustainable industrial development. I will then test this model using a variety of methods and data sets at the national, and state and county levels. In the following two analytical chapters, I will evaluate the impacts of incentives on state-level employment and firm growth, followed by an assessment of the economic effects of incentives in one such state: Georgia. By using this variety of approaches and units of analysis, I hope to shed light on both the macro- and micro-level impacts such incentives have on the industrial economic development of states. In the first study, I use data from the County Business Patterns (CBP) over the years 2002-2013 to view changes in economic activity by state by the level of incentives offered. Using panel data for industry employment, establishment and occupational employment, I use a fixed and random effects regression models to view the relationship between the presence of incentives and the levels of employment and firms in the film industry of each state. Next, I use Georgia as a case study with which to evaluate the degree to which financial incentives for the motion picture industry can create a sustainable network of local firms and workers. I test these theories by using confidential QCEW data to analyze establishment-level activity and relative locations. The results neither completely confirm nor disprove the hypothesis that attracting mobile productions with state tax incentives can establish a nascent industry and generate long-term employment in a region. However, there is some evidence that the number of years the MPIs are in effect does have a positive impact, especially on establishments and occupations. Additionally, the states’ climate and transportation access relative to Los Angeles and other locations are important factors in building a local industry.

Evaluation of the Effect of Rail Intra-Urban Transit Stations on Neighborhood Change

Wyczalkowski, Christopher K 13 June 2017 (has links)
Development of heavy rail intra-urban public transportation systems is an economically expensive policy tool for State and Local Governments that is often justified with the promise of economic development and neighborhood revitalization around station areas. However, the literature on the effects of rail intra-urban transit stations on neighborhoods is relatively thin, particularly on the socioeconomic effects. This quasi-experimental study evaluated the effect of heavy rail intra-urban transit stations on surrounding neighborhoods, using Atlanta, Georgia and its transit authority, the Metropolitan Atlanta Rapid Transit Authority (MARTA), as a case study. Atlanta is an expansive American city, with a large public transportation system, but low population density and no large-scale policies promoting growth around MARTA rail stations. The study period, 1970 to 2014, covers the entire period of MARTA’s existence – stations opened between 1979 and 2000. Neighborhood change was operationalized with a neighborhood change index (NCI), built on the Neighborhood Life-Cycle framework, with an adaptation that incorporates both the filtering (negative NCI) and gentrification (positive NCI) models of neighborhood change. The study differentiates between an initial effect of new MARTA rail stations, and a long-term effect. Control groups were formed using one and three mile buffers, as well as a matching strategy. Difference-in-difference (DID) models find very little evidence of a positive relationship of NCI with the opening of new MARTA rail stations. The economic recovery that began in 2010 is of special interest for housing research. To address this time-period this study utilized two models, with mixed results. The DID model suggested a negative effect of stations on the NCI. To control for selection bias in the 2010 to 2014 economic time-period, this study utilized propensity score matching to balance the treatment and control group on observed characteristics. A time and tract fixed effects model using the matched treatment and control groups found a significant positive effect of stations on neighborhood change. To test the long-term effect, a time and tract fixed effects model (1970-2014) with the NCI as the dependent variable found a positive NCI effect of MARTA stations on neighborhoods. Therefore, overall, positive neighborhood change (on the NCI scale) can be attributed to MARTA transit stations. Since 2002 MARTA ridership has slightly declined; therefore, the study concludes that given stagnant ridership, lack of supporting policy, and the finding of a positive relationship between MARTA transit stations and gentrification, the stations are a positive amenity, and are a significant contributor to neighborhood change. However, neighborhoods are heterogeneous on many dimensions, and the effect of rail intra-urban transit stations on neighborhoods may depend on the tract’s location, service characteristics, accessibility, and many other unobserved characteristics. Future research will supplement this methodology with additional data and compare the effect of intra-urban transit stations on neighborhood change in other cities to better address potential neighborhood heterogeneity.

SUBSISTENCE URBAN MARKETS AND IN-COUNTRY REMITTANCES: A SOCIAL NETWORK ANALYSIS OF URBAN STREET VENDORS IN GHANA AND THE TRANSFER OF RESOURCES TO RURAL VILLAGES

Zook, Sandy 08 August 2017 (has links)
This dissertation uses a mixed method approach to examine the determinants of internal remittances that are connected to the social networks of urban migrant street vendors. Urban street markets are a point of entry for many migrants moving from rural areas to cities in the Global South. The qualitative portion of the dissertation uses an ethnographic approach including participant observation, interviews and focus groups to examine the social networks of street vendors in a market in the municipality of Madina, Ghana. The quantitative analysis codes data from the ethnography in order to conduct a social network analysis using quadratic assignment procedure and logistic regression quadratic assignment procedure to analyze the relationship between attributes of street vendors and remittance behavior. Findings lead to several policy recommendations for the international community, as well as locally based non-governmental organizations, microfinance organizations, national and local governments providing funding or designing interventions affecting street markets or working with individual street vendors.

Essays on Fiscal Institutions, Public Expenditures, and Debt

Pathak, Rahul 08 August 2017 (has links)
This three-essay dissertation focuses on the political economy of fiscal rules in a comparative context and highlights their unintended consequences – an issue that has received relatively little attention in public financial management literature. The first essay examines whether numerical limits on deficits, or balanced budget rules, influence the composition of public spending, particularly in the social sector. Using a combination of fixed effects and GMM regressions on a large panel of developed and developing economies, this essay finds that while deficit targets are effective in improving fiscal balances, they also tend to reduce social spending on health and social protection. This effect is particularly prominent in democratic countries, which often witness overspending problems. Countries that are considering adoption of such rules should carefully examine the effects of these requirements on expenditures that may have long-term positive externalities. Policymakers should explore mechanisms to minimize the distortionary effects of fiscal limits on spending composition. The second essay focusses on whether the adoption of deficit targets by subnational governments in India influenced the composition of public spending. Using a combination of fixed effects and GMM regressions, this essay finds that the adoption of Fiscal Responsibility and Budget Management (FRBM) legislation by Indian states improved their budget balances significantly. However, the post-FRBM period also witnessed significant cuts in development spending. Furthermore, states have reduced their capital outlay and social spending after the adoption of fiscal responsibility laws. Reduced expenditure on development, and capital projects may affect long-term economic growth, therefore future amendments to the FRBM law should explore mechanisms to minimize the distortionary impacts of fiscal targets on the composition of subnational spending. The third essay shifts attention to the effect of supermajority voting requirements on credit ratings and borrowing costs in the subnational debt market in the United States. Using a combination of generalized ordered logit and linear regression analyses on a sample of general obligation bonds issued by American state governments between 2001 and 2014, this essay finds that states with supermajority voting requirements for tax increases are more likely to receive a lower credit rating on their bonds. Furthermore, on average, the states with a supermajority voting requirement pay a premium of 18 to 21 basis points in true interest cost for their bonds. States that are considering adopting supermajority requirements should consider the unintended effects in terms of lower credit ratings and higher borrowing costs while adopting or designing such fiscal rules. The findings of this dissertation inform the policy debate on the subject and improve our understanding of the impact of fiscal institutions that are being increasingly adopted to regulate the behavior of governments across the world.
