      • Bioremediation of hydrocarbons in soil by immobilized mixed cells on menefee humate

        김상용 New Mexico University 1994 해외박사

        RANK : 232975

        The application of immobilized mixed culture was considered for bioremediation of hydrocarbon-contaminated soil. The Menefee Humate was co-immobilized in alginate gel to enhance the microbial activity. The characteristics and kinetic parameters of the immobilized system were investigated in slurry batch reactors as well as soil beds. Biodegradation rates and patterns were obtained from BOD and shake bed experiments using a variety of solutes such as lubricating oil, benzene, toluene, dodecane, heptane, cyclohexane, and glucose. The effect of humate content, immobilization, recycling, and bead size on biodegradation rate, microbial activity, and pH were obtained. The results of the immobilized system's performance and unique features lead to a better understanding of the novel co-immobilized system with mixed culture and Menefee Humate, and show a promising capability on soil bioremediation.

      • Reconstructing the cause and origin of structural fires in the archaeological record of the Greater Southwest (Mexico, New Mexico)

        Lally, James R The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200526

        Archaeologists frequently assume ancient structural fires are intentional incendiary fires. This assumption has become a foundation for behavioral arguments suggesting motives for these supposed intentional fires. The basic assumption that most, if not all ancient structural fires were intentional has not been subjected to rigorous testing. In this research principles of fire science, arson investigation and fire protection engineering, including mathematical computer fire modeling, were applied to the archaeological record of the Greater Southwest. This was done to determine if ancient structural fires were providential, accidental or intentional incendiary fires. Prehistoric sites in Chihuahua and New Mexico were excavated to obtain artifacts and other evidence of fire. A full scale model of a prehistoric room was constructed. After a fire in this room was modeled using a mathematical computer fire modeling program, it was then filled with fuel and burned. This experience, as well as a basic understanding of the chemistry, physics and behavior of fire, was applied to the prehistoric structures that were excavated in Chihuahua and New Mexico. Standards were articulated by which ancient structural fires could be classified as providential, accidental or incendiary. These standards were applied to the excavated sites. Considerations of the room size, construction material, configuration, use and expected fuel load were compared to the physical evidence that was recovered from the ancient structural fires. A prehistoric room fire in Chihuahua was determined to be accidental. An ancient structural fire in New Mexico was classified as being an incendiary fire. The motives behind this intentional fire remain a mystery. Future investigations of structural fires in the archaeological record should take advantage of readily available tools to reach valid conclusions.*. *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).

      • Culturally Responsive Leadership in Bilingual Education: An Exploration of the Practices Implemented by Elementary School Principals in Southern New Mexico

        Peterson, Gabriela New Mexico State University ProQuest Dissertations 2022 해외박사(DDOD)

        RANK : 200511

        This qualitative study identified the culturally responsive school leadership practices implemented by principals serving in elementary schools with bilingual education programs in Southern New Mexico. By utilizing a phenomenological approach, this research revealed four major themes. These themes include (1) use of parental voice in school structures, (2) development of teacher capacity for culturally responsive pedagogy, (3) promotion of inclusive classroom environments, and (4) implementation of meaningful language accommodations for families. These findings suggest that school principals serving in elementary schools with bilingual education programs in Southern New Mexico work with parents, students, teachers, and staff to create elementary schools that recognize the importance of the culture, language, values, beliefs, practices, and traditions of their English language learner students to effectively meet their social, emotional, linguistic, and academic needs. These findings also suggest that school principals serving in elementary schools with bilingual education programs in Southern New Mexico have a comprehensive understanding of the concepts of culturally responsive education and use that understanding to transform their schools into learning spaces where their English language learner students embrace and feel the value of their home culture and language.

      • Compensating college athletes: NCAA Division I-A athletic directors' and university presidents' perceptions

        Wood, Brian D The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200510

        There has been a movement to compensate college athletes beyond the NCAA permitted limits. Some state lawmakers have initiated legislative action that could substantially impact the operations of college institutions and their athletic departments. The purpose of the study was to determine whether or not, NCAA Division I-A athletic directors and university presidents, support legislative measures to provide compensation (beyond the permitted limits of NCAA bylaws) to college athletes. Additionally, the study explored issues related to compensating athletes such as compensation structures, employee status, and possible measures/actions a university may choose to implement. The sample population (N = 231) consisted of NCAA Division I-A athletic directors (n = 117) and university presidents (n = 114). Three universities had two athletic directors, hence the additional three participants in the athletic director population. A total of 63 surveys were returned, which equated to a response rate of 27.27%. Data revealed that 96.8% of study participants felt that college athletes should receive the traditional athletic grant-in-aid (tuition, room, board, and books), while 63.5% indicated that athletes should receive the cost of attendance. Athletic directors and university presidents overwhelmingly did not support and were uncomfortable with actions of some state lawmakers' that would require compensation of college athletes. Participants indicated that compensated athletes would misalign with the missions of the athletic department and the university. Data showed that respondents felt that compensated athletes do not belong in the university environment. Athletic directors agreed that compensated athletes would be classified as university employees. All participants perceived unionized athletes as a threat to college sports. Many participants recognized that they would be unable to finance such an initiative. If compensation was required by law, at least 53.6% of respondents would recommend the reduction or elimination of sports at their university. Participants' perceptions on nine different compensation structures that an institution could possibly implement were assessed. Analysis of data revealed that no definitive compensation structure was favored amongst study participants.

      • Home schooling in New Mexico: A case study of one family's experience

        Higgins, James Brian The University of New Mexico 2002 해외박사(DDOD)

        RANK : 200510

        The purpose of this study is to investigate and interpret the home schooling experience of one family in the state of New Mexico. In addition to capturing the lived experiences of these four family members, a brief history of the home schooling movement in New Mexico is offered in an attempt to frame the context in which current home schooling practices are situated. Themes which emerged from this qualitative study of home schooling include: issues of identity, learning through relationship, the independence in learning that comes as a result of home schooling, a review of teacher practices, a critique of the public school experience from a home schooling perspective, the identification of the aporias in public schools, and a discussion of the benefits that educating at home can offer. This case study which progressed over a period of more than thirteen months, compliments existing information on home schooling by focusing on the child's voice in home schooling practice. Previous studies have interpreted child experiences through an adult lens, which may distort or compromise their thoughts and emotions. This study attempts to capture this child voice in a desire to represent home schooling practice from the major stakeholder's point of view. This study also addresses the transition process of moving from the public school to the home school setting. As this family made its transition, they identified issues of identity, self-concept, and relationship, as areas of concern. Finally, this study contributes to existing knowledge by pointing out the importance of relationship in learning in the home school environment. Previous studies have mentioned home schooling's effect in the building of positive relationships within the family. Though this study supports the findings of the positive bonding which home schooling can offer, it provides a deeper interpretation of the learning process itself and documents the richness of the relational dynamic of teaching and learning in both home school and public school environments. This paper calls for continued qualitative research in the area of home schooling in order to capture the complex dynamics of the thoughts and emotions that are inherently linked to all human interaction. With this new knowledge, government educational agencies, school districts, and local schools may be more informed about the nature of this viable educational alternative.

      • Evaluation of over the counter sales as a syndromic surveillance method for waterborne disease in New Mexico

        Bustamante, Camilla M The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200510

        This research evaluates the use of Over-the-Counter anti-diarrheal medications as a potential syndromic indicator and surveillance mechanism for waterborne disease in New Mexico. The purpose was to determine the usefulness of such data for either supplemental or stand alone use in a system for waterborne disease surveillance. The use of syndromic indicators for waterborne disease was elevated in 1993 after an outbreak of cryptosporidium was detected in Milwaukee Wisconsin by an alert pharmacist who noticed increased sales of over-the-counter medications over a period of time. In 2001, terrorist threats for anthrax exposure to U.S. populations further prompted funding and research for the use of syndromic indicators as early detection mechanisms. Waterborne disease, as related to six reportable pathogens of concern, is suspected to be underreported nationally and in the State of New Mexico, and adults are more likely to self medicate rather than seek medical attention. Though not typically fatal to the general population, some disease strains such as cryptosporidiosis and shigellosis have proven deadly to vulnerable populations. This study utilizes special mapping and evaluates seasonality, temporality and measures of association in order to determine the potential value of OTC anti-diarrheal sales data as part of an overall surveillance program for waterborne disease in New Mexico.

      • Adjusting to economic integration with the United States: Mexico's exchange rate policy and business cycle features since 1980

        Valenzuela, Manuel Valenzuela The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200495

        Mexico is in the middle of a long lasting process of economic integration with its NAFTA partners, especially with the United States. This process started in the 1980s with unilateral trade liberalization and was reinforced in 1994 by the enactment of NAFTA. For more than two decades the Mexican government has adjusted institutions and public policies to achieve economic stability and sustainable economic growth in the new context of globalization and economic integration. In addition to trade liberalization, the Mexican government has implemented successive economic reforms including deregulation of economic activity, privatization of the banking system and state-owned enterprises, restructuring of external debt, and legal reform of rural property. These reforms have contributed to economic stability in the country. However, sustainable economic growth is still to come. In this study we investigate two important issues related to the process of economic integration: Mexico's exchange rate policy and features of the business cycles of Mexico and the United States. Chapter I presents a brief overview of the Mexican economy. Chapter 2 analyzes the role of two different kinds of exchange rate policies (pegged and floating) for the behavior of inflation and economic growth using a vector error correction approach. The main conclusion is that the exchange rate regime does matter for inflation during the 1980--2004 period. With respect to economic growth, however, our findings are not conclusive. Chapter 3 examines the main characteristics of the Mexican and U.S. business cycles and some of their interactions using the classical approach based on second moment statistics as well as modern time series tools. We also investigate the effect of NAFTA on business cycle synchronization in the two countries and the nature of the long-run relationship among them. Our findings indicate that Mexican and U.S. gross domestic products have shared a long-run equilibrium relationship since 1980, with the U.S. driving the Mexican business cycle. It is also clear that the Mexican economy has strengthened its ties with the U.S. economic activity since the enactment of NAFTA. Chapter 4 presents some concluding remarks and suggests some pending tasks for Mexico's economic policy.

      • Acting to learn: The place of performance in university retention for African Americans, Native Americans and Latinos

        Piper Price, Linda The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200494

        The purpose of this research is to examine how performance in the arts effects college admission, success, and retention for African Americans, Native Americans and Latino students. For the purposes of the study, the arts are defined as a performative act of culture. The fields of inquiry investigated are: culture and performance, acting and learning, aesthetics and artistic production. This study also examines the cultural indicator used to identify at-risk students; the nature of institutional education; the social and emotional lives of the students while attending school; choice, freedom, and identity in academic study; motivation and self-regulated learning and the empowering and transforming aspect of the arts. The study was conducted primarily during the Fall 2003 and Spring 2004 school terms. A survey in the Spring of 2003 was given to a random sampling of fifty students from the target groups. Seven students were selected from those completed surveys for the study---three African-Americans, two Native Americans and two Latinos. Another group of six students in the target cultures were interviewed once for the purpose of triangulation. I completed the group as researcher-participant bringing the total number of actors in the study to fourteen. All participants currently attend or have attended Southwestern University in New Mexico. This research follows an arts-based qualitative methodology called "portraiture." This methodology captures the reflective nature of the arts to magnify human understanding and focuses the study on participant expertise. Acting to Learn explores the roles the arts play in the successful education of people from these three cultures and as a means of self-advocacy at university.

      • Alternative public land management: Judging the economic, regional, and institutional context of the charter forest experiment on the Valles Caldera National Preserve (New Mexico)

        Little, Joseph Mikel The University of New Mexico 2005 해외박사(DDOD)

        RANK : 200494

        Tucked away in the 2003 Budget Report of the President is a general proposal for legislative action to establish pilot charter programs on the nation's public lands. The proposal has generated considerable debate and many do not yet fully understand the concept or how it will be applied. However, a charter forest experiment is already underway in northern New Mexico. The 89,000-acre Valles Caldera National Preserve (VCNP) represents the first federal land acquisition to create a charter forest. As a unique public land management experiment, the VCNP merits close scrutiny by land managers, policy makers, and researchers. The objective of this dissertation is to provide an economic, institutional, and policy analysis of the recreation program at VCNP, with particular attention to initial efforts at revenue generation, public access, and program design of the Mature Bull Elk permit auction and raffle. An institutional assessment of the VCNP and initial economic analysis of the elk-hunting program are given in Chapter 2. The economic analysis draws on permit auction and mature bull permit raffle (MBR) ticket sales data to scope-out resource ownership, market structure, revenue generation, and equity issues. In Chapter 3 hunting transactions data is used in a hedonic pricing analysis of the big game hunting market that exists in the four corners region. The primary purpose of the chapter is to identify where the VCNP mature bull elk hunts fit within the context of the regional market. In Chapter 4 stated and revealed preference mature bull permit raffle (MBR) ticket purchase data are used to estimate raffle ticket demand equations with the purpose of analyzing price elasticity of demand, revenue generation, and consumer welfare under alternative policy scenarios. The dissertation concludes with a fifth chapter that briefly summarizes the research presented herein and provides suggestions for future research. The VCNP is a unique landscape and the VCT a unique management institution. The findings provide insight into the applicability and efficacy of the charter forest concept in general and serve to highlight what the VCT can do to ensure its success.
