Elections and Authoritarian Rule: Causes and Consequences of Adoption of Grassroots Elections in China (open access)

Elections and Authoritarian Rule: Causes and Consequences of Adoption of Grassroots Elections in China

This dissertation investigates the relationship between elections and authoritarian rule with a focus on the case of China's adoption of elections at the grassroots level. In this dissertation, I look at the incentives facing Chinese local governments in choosing between holding competitive elections or state-controlled elections, and how the selection of electoral rules shapes the public's preferences over political institutions and influences the citizens' political behaviors, especially voting in elections and participation in contentious activities. The overarching theme in this dissertation proposes that the sources and consequences of Chinese local elections are conditioned on the state-owned resources and the governing costs. When the amount of state-owned resources to rule the local society is limited, the paucity of resources will incentivize authoritarian governments to liberalize grassroots elections to offset the governance costs. The various levels of election liberalization will lead to different consequences in the public's political behavior. An abundance of state-owned resources not only discourages rulers from sharing power with the local society, but also supplies the rulers with strong capacity to obtain loyalty from voters when elections are adopted. As a result, elections under authoritarian governments with an abundance of state-owned resources will see more loyalist voters than elections …

The Power of One Reinforcer (open access)

The Power of One Reinforcer

Animal trainers use shaping to teach many behaviors. However, during shaping, the organism may engage in behaviors other than the target behavior or approximations to the target behavior. If the animal is engaged in other behaviors, the rate of reinforcement may decrease and the trainer may resort to what is sometimes referred to as a “desperation click.” That is, the trainer delivers one reinforcer for a behavior that is not a successive approximation to the target response. Anecdotal reports from trainers suggest that sometimes the animal continues to repeat this other behavior that received only one reinforcer, even in the absence of further reinforcement for that behavior. This study compared whether, during a one minute extinction period, participants spent more time engaged in a behavior that had been reinforced only once after a brief period of no reinforcement or in a behavior that had been reinforced multiple times. Participants, who were university students, played a tabletop game that involved touching and manipulating small objects. Five conditions were repeated twice for each participant: reinforcement for interacting with a training object alone, reinforcement for interacting with a training object with other objects present, reinforcement for interacting with a target object, one reinforcer …

"Looking into the Heart of Light, the Silence": The Rule of Desire in T.S. Eliot's Poetry (open access)

"Looking into the Heart of Light, the Silence": The Rule of Desire in T.S. Eliot's Poetry

The poetry of T. S. Eliot represents intense yet discriminate expressions of desire. His poetry is a poetry of desire that extenuates the long tradition of love poetry in Occidental culture. The unique and paradoxical element of love in Occidental culture is that it is based on an ideal of the unconsummated love relationship between man and woman. The struggle to express desire, yet remain true to ideals that have deep sacred and secular significance is the key animating factor of Eliot's poetry. To conceal and reveal desire, Eliot made use of four core elements of modernism: the apocalyptic vision, Pound's Imagism, the conflict between organic and mechanic sources of sublimity, and precisionism. Together, all four elements form a critical and philosophical matrix that allows for the discreet expression of desire in what Foucault calls the silences of Victorianism, yet Eliot still manages to reveal it in his major poetry. In Prufrock, Eliot uses precisionism to conceal and reveal desire with conflicting patterns of sound, syntax, and image. In The Waste Land, desire is expressed as negation, primarily as shame, sadness, and violence. The negation of desire occurred only after Pound had excised explicit references to desire, indicating Eliot's struggle …

An Assessment of Fruit Offerings for 7Th and 8Th Grade Students in Texas (open access)

An Assessment of Fruit Offerings for 7Th and 8Th Grade Students in Texas

Childhood obesity in America is reaching epidemic proportions. This study explored whether daily online lunch menu information was sufficient to enable parents to advise their children about healthy and unhealthy menu choices in 350 Texas middle schools and whether online menu information strongly correlated with the descriptions of the offerings given by 52 school cafeteria managers in telephone interviews. Although schools are making efforts to describe their offerings, they are not vigorously taking advantage of the opportunity to aggressively inform or educate. They are not coding their descriptions in such a way as to explicitly brand food as healthy or unhealthy. They are also not labeling food as generally required by law for consumer services that provide food (except for the fresh produce that lines supermarket shelves). Instead, they only briefly describe what they are serving in the way of fruit in one or two word snippets. Finally, cafeteria managers’ online descriptions were inconsistent with what they described in interviews. Online and verbal descriptions were sometimes contradictory, raising questions about the accuracy of either type of description.

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language (open access)

An Analysis of the Overt Teaching of the Monitor to Students of English as a Second Language

The overt teaching of the Monitor, or conscious rule awareness, to native Spanish-speaking ESL students was examined to note possible benefits to the students' oral English production. Native Spanish-speaking students of English (the experimental group) were taught an awareness of their ability to self-correct their spoken English. They were then compared to another group of native Spanish-speaking ESL students (the control group) in four areas: Ilyin Oral Interview score, total words produced, errors produced, and interference errors produced. The results of the study lend support to the theory that overt Monitor teaching could be beneficial to native Spanish-speaking students of English. The experimental group showed a significant gain in Ilyin scores and a significant reduction in the number of errors produced.

A Description and Analysis of the Channels of Distribution for Food Products in the State of Kuwait (open access)

A Description and Analysis of the Channels of Distribution for Food Products in the State of Kuwait

This study is intended, first, to describe and analyze the channels of distribution for food products in the State of Kuwait, second, to pinpoint the problems that exist in the food-distribution system, and, third, to make specific recommendations for the alleviation of the problems. Consistent with the objectives of the study and based on the description and analysis of the food-distribution system in the country, it is concluded in the study that Kuwait depends on imports for virtually all of its food; the government plays a major role in the food-distribution system; and the majority of food wholesaling and retailing establishments are small, inefficient, and lack modern marketing and physical distribution techniques. Product shortages and rising food prices plague the food-distribution system in the country. Also, the findings indicate that consumers in Kuwait are generally ignorant and uninformed in the areas of food nutrition and food shopping, and the lack of standardization and grading of food products makes the shopping task of the consumer more difficult.

A Systematic Analysis and Critical Comparison of the Educational Provision for Students in Nigeria with the Available Educational Opportunity for Handicapped Students (open access)

A Systematic Analysis and Critical Comparison of the Educational Provision for Students in Nigeria with the Available Educational Opportunity for Handicapped Students

The problem of the study was the inadequate education of handicapped students in Nigeria. The primary purpose of the study was to develop a construct based on the United States models and research on special education, and to compare educational provisions for Nigerian students with the available educational opportunity for handicapped students. In order to achieve the stated objectives of the study, two methodological approaches were utilized: (1) Likert scale for opinion questionnaires, and (2) personal interviews. Both of these instruments included demographic information about the participants. The questionnaire was categorized into three areas (differences between educational opportunities for non-handicapped and handicapped students, formal learning opportunities for handicapped Nigerian students, and factors for being attentive or not being attentive to special education). The interview instrument focused on special education constraints, responsibility for special education provision, and improvement in education for the handicapped. Based on the findings of the study, the following conclusions were reached. 1. Handicapped Nigerian students do not have equal educational opportunities, as compared to non-handicapped students. Therefore, equal instructional opportunities should be provided for handicapped and non-handicapped students. 2. The federal and state governments of Nigeria should be financially responsible for special education. Therefore, the administration of …

Comparison of Learning Performance Between Students Who Do and Students Who Do Not Use Mobile Technology-based Activities (open access)

Comparison of Learning Performance Between Students Who Do and Students Who Do Not Use Mobile Technology-based Activities

This study examined if using mobile technology-based activities would increase student performance in biological science courses. The study compared two groups of students in lectures and labs. Each group had about 20 students. The mobile group had mobile technology-based activities and the non-mobile group received conventional instruction. The mobile group used links to the website, or a QR Code to access the activities. The non-mobile group had handouts and worksheets over the same content. The research methodology for this study was mixed method. The study was a quasi-experimental design that used instruction method as the independent variable between two groups. The study used formative and summative assessment to compare the performance of the mobile group and non-mobile group in lecture and lab. The student in the mobile group had statistically significantly higher lab exam scores than students in the non-mobile group. Additionally, Students were surveyed about their performance expectancy and effort expectancy using mobile technology for learning, and they were asked about their self-management of learning. Analysis indicated that both groups had similar performance and effort expectancy using mobile technology for learning, but the two groups differed on self-management of learning responses to the survey. Focus groups from the mobile …

Choice for All? Charter Schools and Students with Disabilities

In order to assess the extent and quality of special education services in charter schools in north Texas, the researcher examined data submitted to Texa Public Education Information Management System (PEIMS), and conducted qualitative interviews with selected charter school administrators. Five cornerstones of the Individuals with Disabilities Education Act (IDEA): zero reject, individualized education program (IEP), appropriate assessment, free appropriate public education (FAPE), and least restrictive environment (LRE), were utilized in the assessment of quality. Levels of expertise in federal disability law and fiscal barriers were explored, as well.

A Study of the Correlates of Vocational Bias in Elementary Students (open access)

A Study of the Correlates of Vocational Bias in Elementary Students

The purpose of this study was to determine if any correlation exists between the presence of vocational bias in elementary students and (1) the presence of bias in the textbooks they use, (2) father's occupation, (3) student grade level, (4) level of intelligence, and (5) sex of the student. The population for the study consisted of 368 kindergarten, third-grade, and sixth-grade students from two North Texas school districts. The instrument used to measure student vocational bias was the Were I a Worker attitude inventory developed by P. K. Yonge Laboratory School at the University of Florida under the direction of the Fusion of Applied and Intellectual Skills Research Project. The instrument used to categorize the father's occupations into professional and non-professional groups was the "Two-Factor Index of Social Position" developed by A. B. Hollingshead. The data were collected by having each student respond to the attitude inventory under the supervision of the participating classroom teacher. In addition, the student's I.Q., grade level, sex, and father's occupation were recorded on the test booklet. A notation was also placed on each instrument indicating the type of textbook used by that student. After all the data were collected, the attitude inventory was hand …

Essential Competencies for Entry-Level Management Positions in the Food and Beverage Industry in Taiwan and Mainland China (open access)

Essential Competencies for Entry-Level Management Positions in the Food and Beverage Industry in Taiwan and Mainland China

The purpose of this study was to identify the essential competencies for entry-level management positions in the food and beverage (F&B) industry based on the perspectives of Taiwanese industry professionals across three groups: work experience in Taiwan and/or mainland China, two F&B sectors (Hotel F&Bs and restaurants), and three management levels (first-line, middle, and top). A total of 515 Taiwanese F&B industry professionals participated in this study with 104 participants currently employed in mainland China, some of whom worked previously in Taiwan, and 411 participants working in Taiwan, without work experience in mainland China. Factor analysis produced four dimensions of important competencies: leadership, F&B management, interpersonal skills, and communication skills. Results indicated that communication skills was the only dimension that showed significant difference between participants with and without work experience in mainland China. The findings of this study indicated that 14 of 41 competency items were ranked in the top 10 based on the responses of the three groups. Participants from all three groups ranked "high level of personal integrity" as the most important competence and "ability to communicate orally in proper English" was ranked as the second most important competence by all groups except the restaurant sector. The results …

Inquiry-based science for high school students: a forensic unit

Access: Use of this item is restricted to the UNT Community
This project constitutes an instructional unit for honors biology that involves the use of science in the field of criminal investigation and forensics. Before beginning the unit, the learners should have mastered basic laboratory skills, including use of the microscope. They should also have an understanding of the basic structure and function of DNA and its role in heredity and protein synthesis. The standard time frame is 24 days with 70-minute periods, but can be easily adjusted to meet classroom needs. Several instructional strategies enhance student learning and make science fun. The unit is inquiry-driven and activity-based. Students are surprised by the crime, gather and analyze evidence, and work towards proposing an explanation. This real world problem involves the use of cooperative learning and a variety of assessment techniques.

A Proposed Plan to Teach College Students How to Tune Pianos (open access)

A Proposed Plan to Teach College Students How to Tune Pianos

It is the belief of many tuners that the best education for the young tuner is to do apprentice work in a piano factory where he must learn all the construction of the piano from the frame work of the case to the final setting of the tuning pins. It appears that most tuners are men now in the late forties to late fifties and were either factory-trained or apprentice-trained by an experienced tuner. The situation has changed and the apprenticeship method of training professional men such as lawyers and physicians has long since been discarded as a method of education. It is now the generally accepted plan to go to a college or university where such specialized training is given or offered under the direction and tutelage of specialists, and where students learn other essential subjects, the knowledge of which is necessary to the success of any educated man or woman.

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens) (open access)

Evaluation of the Economic, Social, and Biological Feasibility of Bioconverting Food Wastes with the Black Soldier Fly (Hermetia illucens)

Food waste in the waste stream is becoming an important aspect of integrated waste management systems. Current efforts are composting and animal feeding. However, these food waste disposal practices rely on slow thermodynamic processes of composting or finding farmers with domestic animals capable of consuming the food wastes. Bioconversion, a potential alternative, is a waste management practice that converts food waste to insect larval biomass and organic residue. This project uses a native and common non-pest insect in Texas, the black soldier fly, which processes large quantities of food wastes, as well as animal wastes and sewage in its larval stage. The goal of this research is to facilitate the identification and development of the practical parameters of bioconversion methods at a large cafeteria. Three major factors were selected to evaluate the practicality of a bioconversion system: (1) the biological constraints on the species; (2) the economic costs and benefits for the local community; (3) the perception of and interaction between the public and management agencies with respect to the bioconversion process. Results indicate that bioconversion is feasible on all levels. Larvae tolerate and consume food waste as well as used cooking grease, reducing the overall waste volume by 30-70% …

Effects of Citizenship Curriculum Training on Ninth-Grade Discipline-Problem Students (open access)

Effects of Citizenship Curriculum Training on Ninth-Grade Discipline-Problem Students

This study was conducted to measure the effects of classroom instruction entitled Citizenship curriculum Training on high school discipline. Data for this study were collected and analyzed for fifty-eight ninth-grade students who had been referred to the principal's office three or more times the semester prior to the experimental treatment. An experimental group of twenty-nine students received citizenship curriculum instruction. The control group of twenty-nine students received only the school's traditional curriculum during second period class. Two teachers presented the citizenship curriculum training which included instructional units on beliefs, attitudes, emotions, anger, decision-making, communications, confrontation, positive attention, stress, peer pressure, authority figures, getting along in school, and the society game. Data were collected relative to grade-point average, absences, discipline referrals, and attitude toward high school as measured by the Remitters High School Attitude Scale. T-tests for correlated samples and analysis of covariance examined the effects of the Citizenship Curriculum Training on the four variables measured. The .05 level of significance was used to test the four hypotheses. The results of the study indicate that Citizenship Curriculum Training does not improve the students' gradepoint averages, absentee rate, lower the number of discipline referrals, and does not improve students' attitude as measured …

Students' and Teachers' Perceptions of Mathematics through Their Lived Experiences in Classrooms and Communities

This dissertation includes background on influences of mathematics, mathematics education, and who is viewed as a mathematician leading into three articles exploring students' and teachers' perceptions of mathematics through their lived experiences in both mathematics classrooms and their communities. Using interpretative phenomenological analysis for the methodology, all three articles analyze mathematics autobiographies and semi-structured interviews with five student participants enrolled in the same Algebra I course; Paper 3 also includes the Algebra I teacher. Paper 1 focuses on how students describe their lived experiences in mathematics classrooms. Three themes emerged from the participant data: 1) lack of autonomy and access, 2) feelings hinge on performance in mathematics, and 3) the need for support in mathematics. Each participant shared different experiences, but these experiences can help inform educators how to improve students' experiences in the classroom. Paper 2 sought to understand how middle grade students make sense of what it means to do mathematics in their community. The three themes include: 1) navigating the usefulness of mathematics outside of school, 2) who directs mathematics outside of school, and 3) the need for mathematics in future plans. Connections students made between mathematics and the lives outside of school varied suggesting how broad …

Narratives on College Access and Academic Undermatch: Understanding Latinx Students and Their Families (open access)

Narratives on College Access and Academic Undermatch: Understanding Latinx Students and Their Families

When students are academically qualified to attend a four-year college or university but instead enroll at a community college, they are considered academically undermatched. Research suggests that Latinx students are more likely to academically undermatch than their peers yet they remain the least likely to complete an upward transfer to a university and earn a baccalaureate degree. The purpose of this study was to explore the enrollment decisions of, and familial influences on, Latinx students who were admitted to a university but who initially enrolled at a community college. Using community cultural wealth and funds of knowledge as theoretical frameworks, I examined the narratives of 13 Latinx students and the parents of five of those students. Nine student participants were female and four were male, ranging from 19 to 31 years old. Parent participants were four females and two males, ranging from 43 to 52 years old. Findings from this study are divided into two parts. Student findings revealed navigating the pathway to college was fraught with limited information, even though students acknowledged they had access to resources and their high school counselors and teachers helped in the college search process. However, students still did not feel that crucial information …
