In the last two decades, a concern on how federal forests in the United States are managed has provoked concerns among different stakeholders, including NGOs. The purpose of this thesis is to contribute to the understanding of NGO influence on forest management legislation. Eight aspects were selected and compared in different study cases referring to legislative proposals dealing with forest management in order to define success criteria for a legislative initiative. The study indicates that the following criteria are particularly important to fulfill in order to influence forest management legislation:- The issue to address should be on the political agenda and have high public interest.- Environmental and social aspects should not be at the expense of economic aspects.- The legislative initiative should be prepared in multi-stakeholder processes, including local government and organizations.- The supporters of the initiative should take part in all decision-making processes and advise the Government in aspects related to their areas of expertise.NGOs would likely improve their chances of influencing forest management legislation if they hold a flexible position regarding legislative proposals containing similar or even less strict measures than their own initiatives, look at market oriented schemes as alternatives to legislation, and maintain good relationships with other major stakeholders.

This study examines the results of multiple evaluations of the Cleveland Scholarship and Tutoring Grant Program (CTSP), a state-funded voucher program, by exploring extant evaluations and literature. Attention will be given to the following research question: Does participation in the Cleveland Scholarship and Tutoring Grant Program have the hypothesized positive effect on traditional public school students' academic achievement? Cleveland's voucher program provides an ideal contextualized setting for ascertaining the extent to which school choice programs afford poor families the same educational options available to affluent families. This study concludes that overall there are no statistically significant gains in voucher students' academic achievement. In fact, it appears that some voucher students performed slightly worse in math. The program does, however, afford low-income students the opportunity to attend private secular or religious schools in accordance with the program's initial design and intent.

In Germany, political foundations (Stiftungen) play an important role in shaping civil society through political democracy education. The foundations, however, have also committed themselves to strengthening democratic political and societal structures abroad. Their joint mission abroad is the contribution to democratic structures, information and debate in the countries and regions they are working in. They complement the official German foreign policy, but choose their own priorities and strategies. The focus of this thesis is the German political foundations as actors in democracy assistance. 'Democracy assistance' focuses less on the aspects of technical assistance but much more on political parties and the promotion of civil society as the backbone of democracy. Democracy assistance is a relatively recent international development activity of governments and international organizations. In recent years the international community has come to realize the importance of political parties and a well-functioning political party system for the process of democratisation. Here the German political foundations are working internationally as actors in democracy assistance - independent from the German government but at the same time fully state-funded. The objectives of this dissertation are to understand the work and strategies of the German political foundations as actors in the context of democracy assistance abroad, research their partner spectrums on selected countries, to identify their short comings and to give an outlook of the foundations work in the future in the fast-changing global political environment.

The thesis has one main focus, the purity laws of a religious group in Europe, an original piece of research never done before in the UK. The thesis uses diasporic theories of identity; theories of women and the body; theories of women, their bodies and patriarchal religion and theories of women, purity and pollution in religion, to explain why European Zoroastrian women continue to support six of the purity laws of Zoroastrianism in the year 2003. Purity and pollution are at the heart of the Zoroastrian religion and the research demonstrated that Zoroastrians belief in and knowledge of the six purity laws was strong in 2003.Zoroastrians are a diasporic religious group whose modern origins are in Iran and the sub-continent of India. They have been visiting and settling, from the sub-continent, in Europe, and especially in London, in small numbers since the middle of the nineteenth century.There have been three quantitative surveys of the Zoroastrian community in Europe, in 1976, 1985 and 2003, with each survey building on the last one. Thus, the analytical, quantitative research leading up to the thesis covers a period of nearly 30 years. In the 2003 survey, new questions, never posed before in academic research, were asked about six of the Zoroastrian purity laws, which yielded data for the main focus of the thesis. The women support the six purity laws more than the men and the majority of both women and men affirmed four of the purity laws and rejected two of them.The conclusion of the thesis is that the six Zoroastrian purity laws examined in this research are used in the creation of a hybrid, immanent and liminal religious identity and in some cases ethnic identity, by the women of the European Zoroastrian community; purity laws are known about and matter to these women in Europe in 2003.

The United States government spends billions of dollars on home ownership programs in low and moderate income communities. However, there is paucity of academic research to assess the socioeconomic impacts of these programs. The purpose of this empirical research was to assess their possible impacts. The key research question explored the relationship between low and moderate income home ownership, the independent variable, and the dependent variables of the rates of crime, unemployment, high school graduation, and standardized test scores in the communities concerned. The research design was quantitative-causal. Welfare economic theory formed the theoretical foundation for the study. Using public records, data were collected from four low and moderate income communities in major Midwestern metropolitan areas. The proposed relationships were tested through independent sample t-tests and regression analyses. Results indicated no significant relationship between low and moderate home ownership rate and the rates of the studied socioeconomic indicators. A significant social change implication of this finding would be to relocate federal dollars from housing schemes to more socially and economically relevant programs, such as those geared toward improving educational opportunities in low and moderate income communities.

Since the turn of the century the use of computer-mediated-communication (CMC) has become more widespread in educational contexts and weblogs (blogs), one of the more popular forms of CMC (Bloch, 2007), have been the focus of numerous studies. However, whilst these studies have listed the potential benefits of blog use for language learners, few studies have offered any practical tips for educators who wish to implement the use of writing blogs in the EFL classroom. Moreover, the vast majority of studies have focused on the use of blogs with relatively high-level learners in academic contexts.This small-scale study focuses on how the use of blogs impact on the writing of a group of low-level learners in a tertiary EFL context in Chile. Moreover, it presents a tentative model to explain the different factors that contribute to writing development using weblogs as these learners grapple "not only with a written code but with a linguistic code that is still being acquired" (Raimes, 1985: 232). The findings report that blogs have the potential to aid low-level learners develop their L2 writing, and a number of suggestions are made that may help practitioners facilitate the process.

This study attempts to examine the impact of a trade decontrol policy on food output within the Nigerian macroeconomic context. In other words, the study relates trade liberalization to the national food security situation between 1970 and 2000, by employing descriptive statistics and error correction model (ECM) as the research methodologies.Regional and multilateral trade agreements seem to reduce barriers to the flow of commodities across borders, thus fostering a more efficient allocation of scarce resources as well as raising gross output with positive implications for food security at various levels. Though the trend analyses revealed considerable fluctuations, there existed greater improvements during the trade decontrol era than during the period of trade restriction. The production statistics for both agricultural exports and food showed substantial diversity of performance. Deregulation of the exchange rate and abolition of commodity boards were partly responsible for the significantly positive changes in the cash crop market and enhanced farmers' earnings during the trade decontrol era.One positive development during the trade liberalization era is the emerging trend as well as remarkable improvement in the production of agricultural tradables (cocoa, cotton, groundnut, palm kernel, palm oil and rubber), although this was at the expense of the food crop sub sector.Consumer Price Indices recorded high and increasing values during liberalization as compared to before deregulation. That is, the price situation of foods items was particularly more favourable before deregulation than thereafter. By implication, the purchasing power of most Nigerians, especially wage earners, declined, thereby making them to be less food secured.More specifically, beans appeared to be the most expensive of all the selected food items. The price of beans more than doubled that of guinea corn, maize and millet during the liberalization period under study. This made Nigerians more dependent on less nutritious but cheaper food items, such as cassava meals.The EPC analysis showed that food crops enjoyed adequate level of protection even during liberalization. The protection accorded to agriculture during liberalization resulted in a movement of resources to agriculture in general and non-food crops in particular.Since input subsidy and tariffs are crucial ingredients in the computation of EPCs which recorded some differences between the regulated and liberalized periods, Nigerians were less food secured during the liberalization era. The reason adduced for this is that supportive policies and programmes were not put in place to curtail the rising food prices and generally high inflation rate during the period. In view of this, desirable and workable policies are therefore required to reform as well as improve the efficiency of market process, in order to moderate marketing costs and eliminate undue mark ups.

This thesis focuses on iterative methods for the treatment of the steady state neutron transport equation in slab geometry, bounded convex domain of Rn (n = 2,3) and in 1-D spherical geometry. We introduce a generic Alternate Direction Implicit (ADI)-like iterative method based on positive definite and m-accretive splitting (PAS) for linear operator equations with operators admitting such splitting. This method converges unconditionally and its SOR acceleration yields convergence results similar to those obtained in presence of finite dimensional systems with matrices possessing the Young property A. The proposed methods are illustrated by a numerical example in which an integro-differential problem of transport theory is considered. In the particular case where the positive definite part of the linear equation operator is self-adjoint, an upper bound for the contraction factor of the iterative method, which depends solely on the spectrum of the self-adjoint part is derived. As such, this method has been successfully applied to the neutron transport equation in slab and 2-D cartesian geometry and in 1-D spherical geometry. The self-adjoint and m-accretive splitting leads to a fixed point problem where the operator is a 2 by 2 matrix of operators. An infinite dimensional adaptation of minimal residual and preconditioned minimal residual algorithms using Gauss-Seidel, symmetric Gauss-Seidel and polynomial preconditioning are then applied to solve the matrix operator equation. Theoretical analysis shows that the methods converge unconditionally and upper bounds of the rate of residual decreasing which depend solely on the spectrum of the self-adjoint part of the operator are derived. The convergence of theses solvers is illustrated numerically on a sample neutron transport problem in 2-D geometry. Various test cases, including pure scattering and optically thick domains are considered.

Growth Associated Protein 43 (GAP-43), isolated from rat brain and considered a neuronal marker, is involved in neurite branching, cytoskeleton remodelling, neuronal development and protection. However, GAP-43 mRNA was found in embryonic chicken cells positive to meromyosin, as well as in human satellite cells, myoblasts and myotubes deriving from healthy or dystrophic muscles. Despite these findings, there is no clear evidence about its localization or relationship with other muscle proteins.The aim of this study was to investigate GAP-43 protein expression and localization in C2C12 cells and mice skeletal muscle fibers, using immunoblot and immunofluorescence protocols for confocal mycroscopy.Immunoblot analyses show the presence of GAP-43 in C2C12 cell homogenates as well as in mature muscle fibers. Immunofluorescent images reveal that the protein is localized nearby the external nuclear membranes in C2C12 myoblasts, while in C2C12 myotubes, it has been detected on muscular streaks, in a regular double strand pattern. This localization has been found also in Extensor Digitorum Longus fibers isolated from 1 week, 1 and 24 months old mice. In isolated adult mouse fibers, GAP-43 localization appears to be in relationship with crucial proteins such as triadin, alfa-actinin, RyR, DHPR, as well as mitochondria.In addition, cross-specimen analyses on skeletal muscle cells and mature fibers from Xenopus Laevis (amphibian), rat and human were performed, in order to interpret the results from an evolutionary point of view.In conclusion, these preliminary data confirm the presence of GAP-43 in all the analyzed skeletal muscles, and its localization supports the hypothesis of a possible new functional role in the muscle excitation-contraction coupling process.

A great deal of literature confirms the fact that small family-owned businesses rarely extend beyond the founder of the business. This study explored and identified factors that helped to create a successful family business transition for two African American family-owned businesses in the San Antonio area. One family experienced working through a well thought-out succession plan that successfully passed the mantel from one generation to the next, while the other family experienced going through an unexpected, unplanned business succession that was also successful. Understanding the factors that help create a successful family business transition is difficult because there is very little scholarly research that has an in-depth focus on the African American family business. The research design used was a Phenomenological Qualitative Historical Case Study.The findings revealed that both families' success may be attributed to factors such as being raised by both of their parents and being taught family values, hard work, responsibility, and accountability. Self-preservation, the first law of nature, was taught to make them aware of the importance of taking care of self first, so they could take care of others. As children, they watched their parents at work, which gave them the opportunity to shape and mold their own work ethic with a strong family influence.Most of the children in both families were socialized into the family business and never worked elsewhere. Both families were very active in church and made the church the center of their social life. All of the family members had mentors and/or role models as a child, at school, and at work. The researcher concludes that it is important to note a plan for succession should consist of three elements, all of which must precede the actual succession by a few months. A plan for succession occurred in one case; however, in the second case, it occurred several months after succession took place.

The economic and human costs of diabetes in the U.S. population place an enormous burden on its healthcare system as well as on employers, diabetics, and their respective families. Many Medicare Advantage plans have responded to this burden by implementing diabetes case management programs (DCMPs) aimed at reducing inappropriate health services utilization, improving health outcomes, and containing costs. While the use of DCMPs is common to many health plans, the research regarding their effectiveness has been sparse or inconclusive. The purpose of this study was to help fill a critical gap in the research literature by evaluating the effect of a diabetes case management program known as CareContact on a Medicare population in Texas. The study population consisted of 2,972 confirmed diabetic members who were continuously enrolled in SelectCare of Texas, a Medicare Advantage plan, for the two-year period between January 1, 2005 and December 31, 2006. To be eligible for this study, diabetic members had to have a minimum of 6 months without exposure to CareContact and 6 months of exposure to CareContact after the initial exposure. Twelve separate cohorts, defined by date of initial program exposure, were evaluated using a one group interrupted time series design. Cross sectional time series analysis, which combines ordinary least square regression techniques and time series analyses, was used to evaluate program effectiveness. After controlling for confounders and the effects of time, the data indicated that membership in the DCMP was associated with increased costs and increased utilization over the two-year study period. The study points to the need for further research into the effectiveness of diabetes case management programs, especially for participants of Medicare Advantage health plans.
