The Future Impact Of Adoption Of Soil Conservation Strategy At Family Level In The Highlands Of Ethiopia, Senait Regassa, Werner Doppler

International Conference on African Development Archives

In the highlands of Ethiopia, soil erosion is a bottleneck to maintain land productivity. In order to mitigate the problem of land degradation, the Soil Conservation Research Project (SCRP) developed and disseminated a number of soil conservation techniques. The studies done so far dealt with the impact of these techniques on yield and profitability of farming. However, poor farmers take not only yield and profitability into consideration but also many other factors. This study was initiated to assess the future impact of adoption of bund construction on family income, external labour requirement, cash balance, credit need, and dependence on purchased …

Market Incentives, Farmers’ Response And A Policy Dilemma: A Case Study On Expansion Of Chat Production As A Cash Crop In The Eastern Ethiopian Highlands.\, Tesfaye Lemma Tefera, Johann Kirsten, Sylvain Perret

International Conference on African Development Archives

This paper discusses the reasons for and effects of the dramatic expansion of chat production as a cash crop in the Hararghe Highlands of Ethiopia. Despite the Ministry of Agriculture’s deliberate attempt to marginalize and openly discourage chat production, farmers continue shifting their scarce resources to chat production. Using data generated by a rural livelihood survey from 197 randomly selected households, economic and non-economic factors contributing to the expansion of chat production are identified and its food and nutritional security impact was analyzed. The case study confirms once more again the power of market incentives in encouraging agricultural activity of …

Parallel Simulation Of Microflows By Dsmc And Burnett Equations, Yichuan Fang

Dissertations

The primary objective of this dissertation is to numerically simulate and study the heat transfer and flow characteristics in fluidic microelectromechanical system (MEMS). In typical microfluidic MEMS applications, the ratio of the gas mean-free-path to the characteristic length scale, or the Knudsen number, can be large. The traditional mathematical models of continuum fluid based on the Navier-Stokes equations may become invalid because of their constitutive relations of viscous stress and heat flux.

In this study, the direct simulation Monte Carlo (DSMC) method and the conventional Burnett equations are applied to model the microflows in microchannels from molecular and continuum point …

Stratigraphy Of Lake Michigan Lobe Deposits In Van Buren County, Michigan, Steven P. Beukema

Masters Theses

The surficial glacial deposits and landforms of Van Buren County were recently mapped at a 1:24,000 scale as part of a STATEMAP project. Several borings were drilled to supplement the surface data. Six of these borings were characterized in detail by means of gamma ray logging, textural analysis, and X-ray diffraction of the clay-sized fraction of the diamicton units.

Results from this study reveal two diamicton units at stratigraphically distinct positions that can be correlated across the county and that are separated by a thick sequence of lacustrine sediments. Correlation of diamicton and lacustrine units was accomplished by analyzing several …

Changing Women: An Ethnographic Study Of Homeless Mothers And Popular Education, Lorna Rivera

The Journal of Sociology & Social Welfare

This article discusses ethnographic research conducted between 1995 and 1998 that studied the impact of popular education on the lives of fifty homeless and formerly homeless mothers. Data collection involved indepth interviews and participant observation in a family shelter located in one of Boston's poorest neighborhoods. The article argues that popular education increased the women's self-esteem, they were inspired to help other low-income women, they learned to advocate for their rights and they became more involved in their children's education. The findings suggest that popular education can best address the academic, personal, and community goals of very poor women.

Understanding On Concepts Of Force Of Thai Freshmen, Chokchai Usawinchai

Dissertations

The central concept of Newtonian mechanics is force. Without this concept, the students would find the rest of mechanics very difficult to master. Based on this hypothesis, the understandings and misconceptions of Newtonian mechanics were investigated.

Three hundred eighteen Thai freshmen participated in this study. The freshmen were divided into two groups according to their high school locations, Bangkok and other cities of Thailand. The Force Concept Inventory was used to probe the freshmen's understandings and misconceptions. The SPSS and EXCEL programs were used to analyze the data. The translation of the FCI into Thai and its subsequent validation is …

A Comparison Of Different Schemes For Selecting And Estimating Score Functions Based On Residuals, Ali A. Al-Shomrani

Dissertations

In a linear model when the errors follow a normal distribution, least squares methodology is most powerful. However, when the assumption of normality of the error distribution is not met then there exist methods which are more powerful than least squares methods. Rank-based methods form one such class. These methods depend on the selection of a score function [varphi]( u ). The correct choice of [varphi] leads to an optimal (efficient) analysis, but its selection depends on the error distribution which is not known.

In this thesis, we explore different schemes for score selection. Some of these schemes are functions …

Cellular Proliferation, Death And Histology In Gambusia Affinis Livers After Exposure To 2-Aminofluorene And Benzidine, Susan J. Lentz

Dissertations

A fundamental need exists for aquatic animals in the biomonitoring of aquatic ecosystems for environmental carcinogens. G. affinis, a small fish species, is selected for this study due to its hardiness, non-migratory nature, geographic diversity and ability to develop tumors. Molecular tools for cellular proliferation and death are examined for use with G. affinis. Additionally, these tools are used to investigate the early carcinogenic effects of 2-aminofluorene and benzidine, both individually and combined, on G. affinis livers.

Antibodies to proliferating cell nuclear antigen (PCNA), p53, cleaved caspase-3 and cleaved poly(ADP-ribose) polymerase (PARP) were examined for use in G. …

New Graphical Approach On The Analysis Of Experimental Data, Suha Sari

Dissertations

This study presents a new graphical method to identify significant effects in factorial experiments. The proposed methods are obtained for the different cases in which the design can be of full factorial or fractional factorial and the factor levels can be pure or mixed.

We focus on the different decomposition methods, for example orthogonal components system and orthogonal contrast method, to make use of the chisquare plot which requires that the sums of squares are of the same degrees of freedom. Examples and simulations illustrating the different cases of the procedure are presented.

The Avifauna Of Bawwab Al-Ghazal: A Zooarchaeological Analysis, Elissa A. Kinzelman

Masters Theses

In 1998 the Neolithic archaeological site of Bawwab al-Ghazal (ca. 11,500- 7,500 BP) was excavated by a team of researchers from the University of California, Riverside and Whitman College. Among the many artifacts recovered from the site, ranging from stone and shell beads to stone tools and related debitage, were an abundant sample of bird bones. Excavators shipped the sample, consisting of some 407 specimens, to the Anthropology Department of Western Michigan University for a faunal analysis.

This study seeks to illustrate the importance of bird remains in the archaeological record. The avifaunal analysis of Bawwab al-Ghazal began with identifying …

Optical Solitons In A Three-State Medium, Talal Ghannam

Masters Theses

When a beam of light propagates within a typical medium, absorption is a common phenomenon. This happens when the frequency of the light is close to a resonant frequency of the atoms composing the medium. But in the past few decades, it has been shown that in certain circumstances, carefully chosen pulse shapes are able to propagate without significant absorption even when the frequency of the light is close to an atomic resonant frequency. It was called Self Induced Transparency (SIT).

This phenomenon was intensively studied in the two-state systems. On the other hand, the three-state systems seems not to …

Reform Mathematics, Melissa Sue Vegter

Honors Theses

Why would the National Council of Teachers of Mathematics want to adopt a set of standards? Normally, groups adopt standards in order to state goals, promote change, and ensure quality. Therefore the NCTM (National Council of Teachers of Mathematics) wanted to state these new goals. Schools, teachers, students, and parents, at that time, had no protection from poor education. In 1989, the Board of Directors and the Commission believed that if students are to be adequately prepared to live in the twenty-first century, new standards should be created in order to achieve this. At this time in history, the economic …

The Use Of Quality Indices For Successful Programs For Students With Emotional/Behavior Disorders In The State Of Michigan, Alice Brouwer Hoekstra

Dissertations

Recent research studies have determined that students with emotional and behavior disorders (EBD) are the most difficult to integrate into the general education environment. Students with EBD are most likely to be educated in separate settings and least likely to be found in traditional education environments. However, the mandate of the Individuals with Disabilities Education Act reauthorized in 1997 (IDEA '97) and the Least Restrictive Environment (LRE) regulation indicates all educators, including administrators, have the responsibility to challenge teachers and schools to be more inclusive regarding students with EBD and to provide services that better support students in this setting. …

The Tragedy Of The Rivers: Building Authority Over The British Water Environment, Kevin B. Vichcales

Dissertations

"The Tragedy of the Rivers: Building Authority over the British Water Environment" examines the problem of rivers as common public resources in modern Britain. Viewed historically, the enduring problem of environmental pollution control in Britain has been the establishment of regulating authority over aspects of nature that are regarded simultaneously as economic resources, public utilities, and public amenities. Legislators, subject to pressure from industrial polluters, political parties, and advocates for environmental quality, sought at different times to locate authority at local, regional, national and extra-national levels. Each effort failed to resolve the issue of authority over the environment, because administrative …

The Extent To Which Teachers And Principals Perceive High Schools As Learning Organizations, Scott Kemple

Dissertations

The purpose of the study was to conduct an assessment of the culture and leadership of a sample of Michigan high schools as perceived by their teaching staff and principals.

The variables of culture and leadership are primary indicators of whether a school is viewed as a learning organization by the faculty, staff and administration of the school (Leithwood et al., 2001). Five primary questions were examined: (1) To what extent are high schools perceived as learning organizations by their principals? (2) To what extent are high schools perceived as learning organizations by their teachers? (3) Is there a difference …

Development Of Kohonen Neural Network Application As A Pattern Recognition System For An Electronic Nose, Lori Lynn Evesque

Masters Theses

Electronic noses are used to identify and characterize unknown odors in industry. Chemometrics and neural network algorithms are used as pattern recognition systems for these devices. Experimentation with Kohonen clustering as the pattern recognition system for electronic noses was not noted prior to 1997. [BEG] This thesis investigated the use of a Kohonen neural network algorithm as a clustering algorithm for electronic nose data using the chemometrics algorithms built into the electronic nose as a performance standard. A secondary aim was to improve the clustering and identification capabilities of the Kohonen network.

The unsupervised Kohonen network was not able to …

Multiobjective Optimal Control Problems With Endpoint And State Constraints, Kirsty J. Eisenhart

Dissertations

In this thesis we consider nonsmooth multiobjective optimal control problems in terms of a general preference on [Special characters omitted.]. The optimal control problems considered involve differential inclusion, endpoint constraints and state constraints. No convexity assumption is needed on the differential inclusion. Examples of common preferences are given, and the idea of approximating a preference is introduced. Euler-Lagrange necessary conditions and a form of the maximum principle are developed for closed preferences (and those that can be approximated by closed preferences) in terms of the limiting subdifferential. As a consequence, this is the first result in the literature for lexicographical …

Student Ecosystems Problem Solving With Computer Simulation, Melissa A. Howse

Dissertations

Computer simulations, such as the BioQUEST Environmental Decision Making (EDM) program, represent a viable supplement or alternative to traditional science teaching approaches. This study concentrated on the manner in which knowledge is acquired and then disseminated through the use of the simulations. In addition, the study took into account the nature of science by revealing what notions of ecosystems and simulation were revealed when students encountered concepts imparted to them via this method. The following research questions guided this study: (1) What content knowledge do students use to solve ecology problems? (2) What procedural knowledge do students use to solve …

"For The Family": Asian Immigrant Women's Triple Day, Kamini Maraj Grahame

The Journal of Sociology & Social Welfare

This article examines how Asian immigrant women manage the demands of family,job training, and paid work in their new society. Using institutional ethnography, a feminist research strategy developed by Dorothy Smith, the study begins with the women's experiences to explore the extended social relations which give shape to them. The study argues that among those extended relations are the organization of the labor market in the contemporary period, immigration legislation, and the ideological practices embedded in developing, managing, and administering public policies such as job training. A critical eye is turned to social science discourses on family which penetrate the …
