The Effect of Linkages on Science and Technology at Historically Black Colleges and Universities

Brice, Kathryn T. 01 September 2006 (has links)
Historically Black Colleges and Universities (HBCUs) face the 21st century with questions about change and adaptation to an increasingly science and technology oriented society. They face the challenge of finding a strategy by which they can utilize current resources and energy to maximize their science and technology development. Using a mixed methods research design, this study conducted an analysis of science and technology at HBCUs. The primary objective was to determine what theories (when implemented they are termed strategies) account for the development of science and technology at successful research oriented HBCUs. This was accomplished through a secondary objective – to assess productivity outputs at HBCUs using various science and technology indices. The results and findings can be summarized by stating that the selection of strategy is dependent on the maturity of the HBCU’s science and technology program. An HBCU that is seeking to initiate a science and technology program should pursue a strategy of federal or state policy supportive of introductory efforts. HBCUs with established science and technology programs that are seeking growth strategies should look toward collaborations and partnerships for the purposes of forming networks and clusters. The formation of joint ventures, partnerships, and networks will further develop their science and technology programs. Leadership is a sustaining factor that enhances the effectiveness of both policy and linkages.

Toward an Understanding of the Revenue of Nonprofit Organizations

Horne, Christopher Scott 01 September 2006 (has links)
Understanding the composition and distribution of the revenue of nonprofit organizations (NPOs) is key to understanding NPOs themselves. This research uses revenue data for 87,127 charitable NPOs to draw three main conclusions. First, revenue structures of NPOs vary widely by subsector and organizational size, with many NPOs demonstrating revenue structures that might be considered uncharacteristic of the nonprofit sector. Second, despite the concerns of many nonprofit scholars, heavy dependence on either government funding or charitable contributions is atypical of NPOs. And third, nonprofit revenue is highly concentrated in relatively few NPOs. The description of revenue expands to examine the relationship between two important sources of revenue, charitable contributions and government subsidies. Nonprofit scholars have long theorized that government funding diminishes charitable giving. This research finds that the effect of subsidy on charity varies substantially among the nonprofit subsectors, but, contrary to widely accepted theory, these effects are more often positive than negative: More than half of government funding of the nonprofit subsectors appears to spur an increase in charitable giving, whereas only 6 percent of government funding is associated with decreased giving. This research suggests that effects of subsidy on charity are less likely due to the decisions of donors than to the decisions of NPOs themselves. These findings assuage some concerns about the future of the nonprofit sector but substantiate others. As government increasingly relies on NPOs to deliver government-funded services, it appears unlikely that NPOs will suffer decreases in charitable giving, and government funding may even enable NPOs to increase revenue from charitable giving. But marginal changes in charitable giving will not mitigate what many see as a distressing move away from reliance on charity toward generating fees for services and generally becoming more business-like. Whether these findings represent a nonprofit sector betraying its charitable roots, diluting its power to effect social change by "corporatizing," emphasizing service delivery at the expense of advocacy, or becoming more efficient, financially stable, and responsive to market demands remains a matter of debate, but debate better informed by the understanding of nonprofit revenue provided by this research.

Two Essays on Corporate Income Taxes and Organizational Forms in the United States

Hu, Zhenhua 01 September 2006 (has links)
Corporate income taxation has a profound impact on economic behavior in the United States. This dissertation focuses on two aspects: the impact of dividend taxation on investment and the impact of corporate income tax exemption on nonprofit organizations activity. The first essay compares dividend payout ratios of C and S corporations to test the validity of the traditional and the new views on dividend taxation. Average corporate income tax rate is used as an instrumental variable. The results support the traditional view. The second essay focuses on whether the exemption of nonprofit organizations from the corporate income tax affects the competition between for-profit and nonprofit hospitals. Time series and panel data analysis show that tax subsidies to nonprofit organizations have a positive impact on nonprofit hospitals’ market share.

The Effect of Proximity to Commercial Uses on Residential Prices

Matthews, John William 01 September 2006 (has links)
As distance from a house to retail sites decreases the price of a house should increase, ceteris paribus, because of increased shopping convenience. On the other hand, as distance decreases price should also decrease because the house is exposed to increased spillover of disamenities – noise, light, traffic, etc. – from the retail use. The study uses Computer Assisted Mass Appraisal data and a parcel level Geographic Information system map from King County (Seattle) Washington. An hedonic process is used to estimate the price effects of both the expected positive and negative price effects. Travel distance is a proxy for convenience and Euclidian distance is a proxy for negative spillovers. Standard hedonic housing price variables are used for control along with distance to other classes of non-residential uses and indexes of neighborhood street layout and connectivity. In traditional gridiron neighborhood, both convenience and negative spillovers have the expected effect on housing price. The net effect is a price effect curve with a net decrease in price at very short distances between houses and retail sites. But, beyond a short distance to the extent of convenient walking distance (about ¼ mile) the net effect is positive. In a non-traditional edge city type neighborhood, there is no effect, either positive or negative. This is due to the much greater distances between residential uses and retail uses in this type neighborhood that result from zoning that segregates land uses and long travel distance resulting from curvilinear street layout.

A Study to Develop Strategies for Proactive Water-Loss Management

Park, Hyun Jung 26 June 2007 (has links)
Water conservation is one of the important policy concerns. However, most water conservation practices have focused primarily on reducing use by customers. Since a large amount of water lost in supply systems causes water providers to lose money, resources, and reliability, and the current passive approach cannot deal with water losses effectively, a proactive approach is necessary for water-loss management. The goal of this study is to help policymakers and water utilities develop strategies that proactively solve water losses. To develop strategies for water-loss management, it is essential to identify key factors that determine the level of water losses as well as the factors that encourage the adoption of the innovative control practices. Using three different datasets and statistical methodology, this study analyzed the factors associated with water losses and utilities responses to the problems. Based on case studies, this study explored managers perceptions about the adoption of water-loss management and identified organizational characteristics that may influence managements decisions to adopt such strategies. Operational and Maintenance (O and M) factors had the most significant impacts on water losses. In particular, system size, represented by total production or population served, and infrastructure rehabilitation were crucial factors. The effects of some internal factors on water losses were predicted but those of several internal factors were rather unclear and relatively complicated. This study confirmed that utilities were more likely to be motivated to combat water losses if certain external conditions, such as higher water demand, limited resource availability, and institutional pressure exist. This study found several internal and external factors associated with the adoption of proactive water-loss management; however, internal factors seemed to dominate in the decision-making processes over such adoption. The utilities that have already adopted proactive water-loss management seem to be more amenable to adopt new practices because they have certain characteristics and their managers have more positive perspectives. The findings suggest several policy implications and recommendations for the water industry. Finally, this study discussed limitations of the study, and suggestions for further studies.

Do Different Expenditure Mechanisms Invite Different Influences? Evidence from Research Expenditures of the National Institutes of Health

Kim, Jungbu 01 October 2007 (has links)
This study examines 1) whether the different expenditure mechanisms used by the National Institutes of Health (NIH) invite different sources of influences on the budget process and thus on the expenditure outcomes and 2) whether the frequent use of omnibus appropriations bills since 1996 has changed budget levels of the institutes under the NIH. The NIH uses two major expenditure mechanisms with very different beneficiary groups: the principal investigator-initiated Research Project Grants and Intramural Research. Drawing on theories of motivations of public officials and of political clout of agency heads and considering empirical studies of the effect of omnibus legislation, this study reveals the following: 1) directors with more public service experience are more successful in securing a higher budget for their institutes; 2) while the directors are found to be driven by public service motivation, when it comes to expenditure allocation between two different mechanisms, they behave in a self-interested manner, representing the interests of the institutional sectors where they have developed close relationships; 3) with ever-increasing budgets between 1983 and 2005, the institute directors have chosen to seek higher budgets rather than merely avoid the risk of budget cuts; 4) although the advisory boards are purportedly used to seek private input for the priority setting, they tend to increase intramural more than external research project grant expenditures; 5) the practice of omnibus appropriations bills significantly benefits the institutes under the NIH such that with omnibus legislation the institutes' total expenditures have more than doubled controlling the other factors; and 6) there are significant differences in the effects of the director's public experience and the number of advisory boards and their membership both (i) between disease-focused institutes and nondisease institutes and (ii) with and without omnibus legislation. The effects of the director's public service experience and the advisory boards have more budgetary impact in the general science-focused institutes than in their disease-focused counterparts. The influence of the advisory board and of the institute director's public service experience on the individual institute's expenditure level is significantly diminished by the frequent use of omnibus appropriations bills.

Overcoming the "Do-Gooder Fallacy": Explaining the Adoption of Effectiveness Best Practices in Philanthropic Foundations

Ashley, Shena Renee 01 October 2007 (has links)
An adoption model was proposed to examine the influence of four types of organizational factors- organizational capacity, organizational structure, operating environment and grantmaking orientation- on the adoption of four effectiveness best practices, formal evaluation, knowledge management, leadership development and operating grants in philanthropic foundations. Data were collected from a national survey of foundations and the Foundation Center database. The results indicate that the grantmaking orientation of a foundation is the greatest indicator of adoptive behavior. Furthermore, capacity constraints are most relevant to the adoption decision when the adopting practice requires significant investments of time, money and expertise. Given the social and political context in which the effectiveness best practices are associated, this dissertation research has broad relevance for the ways in which foundation behavior is perceived and the means by which that behavior is shaped through policy and practice.

Public School Responses to Charter School Presence

Ertas, Nevbahar 01 October 2007 (has links)
As charter schools continue to proliferate across United States, their impact on the public education system is becoming an increasingly important public policy question. Charter school proponents argue that combined pressures of consumer choice and market competition will induce traditional public schools to respond by providing higher quality education and promoting innovation and equity. Skeptics worry that charter schools pose risks of segregating students by race and economic level, and reducing per-pupil resources available to traditional public schools. This dissertation provides a comprehensive evaluation of the effects of charter schools on regular public schools by addressing the following questions: 1) How do the charter schools affect the racial, ethnic and cosio-economic distribution, student-teacher ratios and achievement of traditional public schools? 2) How do the size and scope of competitive effects vary according to different measures of competition? Using two-period panel data from the National Center of Education Statistics (NCES) Common Core Data (CCD) for traditional public schools in Florida, New Jersey, Texas and Ohio, I compare changes in racial and ethnic distribution, student-teacher ratios and achievement in public schools that do and do not face competition. I use a variation of the difference-in-differences (DD) estimation strategy to study the effect of charter schools on the outcome measures. The findings from the study suggest that introduction of charter schools in the educational landscape has affected student distributions, and at least in some cases, student-teacher ratios and the performance of traditional public schools. Charter schools seem to contribute to declines in the share of non-Hispanic white students in traditional public schools in all four states. The results show variation in other outcome areas across states and competition measures. The findings highlight the importance of monitoring what will happen to non-choosers in traditional schools as well as the role of considering state context and empirical measures while generalizing from charter school studies.

Mitigating and Preparing for Disasters: A Survey of Memphis Organizations

Sadiq, Abdul-Akeem Ademola 19 December 2009 (has links)
Disaster researchers have established the determinants of preparedness and mitigation at the household level of analysis. However, at the organizational level, there is limited research and no theory to guide research on the determinants of preparedness and mitigation. The main goal of this study is to answer the question "what are the determinants of mitigation and preparedness at the organizational level?" The data come from a survey of 227 organizations in Memphis, Tennessee. This study uses Tobit regression technique to identify the determinants. This study finds that organizational size and concern over disaster impact are strong positive determinants of mitigation and preparedness in organizations. In addition, there is a significant and non-linear relationship between organizational obstacle and mitigation and preparedness activities. The study concludes with policy implications and recommendations for future studies.

Uses and Nonuses of Patented Inventions

Jung, Taehyun 19 December 2009 (has links)
Innovation comprises the processes of invention and commercialization. While the importance of innovation, especially commercialization, has been widely recognized, existing studies have largely overlooked the commercialization process. By examining the determinants of uses and nonuses of patented inventions from firms at the levels of technology, organization, and project/invention, this study attempts to help fill a critical gap in the literature. In doing so, it enriches theoretical understandings of innovation and, in particular, builds on the evolutionary explanation of technology development, the Teecian framework on profiting from innovation, Transaction Cost Economics (TCE), the Knowledge-Based View (KBV), and open innovation and innovation network perspectives. It also reveals an empirical reality of commercial use and strategic nonuse of patents. The study is based on a novel dataset constructed from multiple sources: inventor surveys, the United States Patent and Trademark Office online database, and COMPUSTAT, among others. After examining the factors affecting overall propensity to commercialize patented inventions, this study explores the factors that affect the organizational paths of commercialization. The empirical estimation indicates that technological uncertainty and a strong internal position of complementary assets raise the propensity for internal commercialization. The study argues that openness of innovation processes and network relationships should affect the choice of commercialization paths. Consistent with the hypotheses, empirical estimations show that external industrial knowledge increases the propensity of internal commercialization. The study also indicates that collaboration has diverging effects on the choice of commercialization paths. While collaboration with firms in vertical relationships tends to favor internal commercialization, collaboration with firms in horizontal relationships tends to favor external commercialization (licensing, start-up). Finally, the study reports findings on the strategic use of patents and then tests hypotheses about the factors driving strategic nonuse. It concludes that a significant portion of U.S. patents are indeed filed for strategic reasons. It also finds that characteristics of technology and firms are significantly associated with different strategies. In particular, firms are more likely to use a patent for strategic defensive purposes when they have larger amounts of assets. The study concludes with discussing managerial and policy implications.
