Respiratory Responses in the Freshwater Snail (Pomacea Bridgesii) are Differently Affected by Temperature , Body Mass,and Oxygen Avalability

Description: Pomacea bridgesii is a snail species native to tropical and sub-tropical regions, where it usually faces variability in water, temperature and oxygen level. This study of the effect of temperature on mass-specific oxygen consumption (ṀO2) and its relation to body weight shows that the ṀO2 of juvenile snails in normoxia (18-21 kPa) acclimated at temperature of 25°C ranged from 5 to 58 µMol O2/g/h, with a mean of 41.4 ± 18.3 µMol O2/g/h (n=7). Adult snails in normoxia at 25°C show less variation, ranging from 13 to 23 µMol O2/g/h , with a mean of 24.4± 6.1 µMol O2/g/h (n=12). The Q10 value for juvenile snails was higher in the interval 25-30°C (Q 10=5.74) than in the interval 20-25°C (Q10= 0.286). In adult snails, Q10 was higher in the interval 20-25°C (Q10=3.19). ṀO2 of P. bridgesii in relation to body weight showed a negative linear correlation between metabolic rate and body weight with b values between 0.23 and 0.76. Also, both juvenile and adult snails exhibited weak O2 regulation. In general, the different respiratory characteristics between juvenile and adult snails might be related to the differences of individual life history, which caused them to perform differently in face of temperatures change. Additionally, Pomacean snails species originated in tropical habitats where there is a lack of thermal fluctuation. For this reason, Pomacean snails may be less likely to have evolved effective thermal acclimation capabilities.

Wilderness and Everyday Life.

Description: I challenge the dualistic view of wilderness that has influenced wilderness philosophy, politics and experience in recent years. In its place, I offer an alternative vision that recognizes wilderness areas and working landscapes as complementary elements of a larger, inhabited landscape characterized by a heterogeneous mixture of human-land relational patterns representing various points along an urban-wilderness continuum. In chapters 2 through 4, I explore the philosophical, political and experiential implications of this wilderness-in-context vision. Experienced and understood as part of the landscape we call home, wilderness may engender, renew, and sustain an engaged and integrated wilderness practice involving regular contact with wilderness places, committed activism on behalf of wild lands and their inhabitants, and grounded reflection on the meaning and value of wilderness in our everyday lives.

Practices, Procedures, and Techniques in Auditorium Work at the Elementary Level, with Special Emphasis on the Elementary Schools of Dallas, Texas

Description: The purpose of this study was threefold: (1) to write a narrative account of the meaning, objectives, and functions of -auditorium work in public schools and to note the importance of providing for pupil participation in auditorium classes, and recommended practices in planning for and presenting programs in this phase of the educational situation; (2) to develop in detail the practices, procedures, and techniques contained in printed and mimeographed materials distributed by the Board of Education to auditorium teachers to serve as guides in conducting auditorium work in the elementary schools of Dallas, Texas; and (3) to evaluate these instructional materials in the light of modern practices, procedures, and techniques advocated by authorities in the field of auditorium work. As an outgrowth of these three phases of the study, it was believed that certain conclusions might be evident as to the efficacy of the auditorium work in the elementary schools of Dallas in so far as it could be determined by a careful examination of materials prepared for the use of auditorium teachers in conducting their classes. It was believed, also, that it might be possible to make recommendations for the improvement of auditorium work in the elementary schools of Dallas in the light of the instructional materials now used by auditorium teachers as compared to modern conceptions of auditorium advanced by authorities in the field.

American Response to Military Coups among Her Allies: Greece--The Colonels' Coup

Description: The focus of this thesis is Greece after the 1967 Colonels' Coup. After an analysis of American responses to military coups among allies since 1949, the Greek situation is explored in depth. Emphasis is given to Congressional and Executive infighting and bureaucratic interpretations of policy. The two presidents who dealt with the Colonels are studied for personal reaction. Sources include the New York Times and its Index, the Department of State Bulletins, current Greek history books, Congressional Hearings and other documents relating to Greece. Major conclusions are that Congressional- Executive infighting produced a meandering non-policy toward Greece, and there was a difference in Johnson's and Nixon's reaction with the latter being more pragmatic verbally but less effective factually.

Heterosexist Harassment and Rejection, Emotional Social Support and Perceived Stress in a Lesbian, Gay and Bisexual Sample

Description: The minority stress theory suggests LGBs experience greater stress levels due to their sexual minority identities; thus, they are more prone to psychological distress. Poor mental health is linked to internalized homophobia and heterosexism. However, affirmative social support may mitigate the stress response via the buffering hypothesis. My model posits that LGBs are more likely to report perceived stress; however, affirmative social support can mitigate stress. I investigated the relationship between perceived stress and sexual minority identity. I explored the relationship between heterosexism, emotional support and perceived stress and the moderating role of social support in my LGB sample. I conducted a hierarchical linear regression to test my model, which accounted for 29% of the variance in perceived stress. Heterosexism and emotional support were significantly associated with perceived stress. I failed to find a moderating role of emotional support. Limitations, strengths, future research and implications are discussed.

Evaluation of Agreement among Respondents to Anecdotal Assessments and Correspondence between Anecdotal and Experimental Analysis Outcomes

Description: Study 1 evaluated agreement among five respondents using the Functional Analysis Screening Tool (FAST), the Motivation Assessment Scale (MAS) and Questions About Behavioral Function (QABF). Respondents provided ratings for 20 target behaviors exhibited by 10 individuals. At least 4/5 raters agreed on the primary maintaining variable in 80% of cases with the FAST, 70% of cases with the MAS, and 55% of cases with the QABF. Study 2 evaluated correspondence between results of anecdotal assessments and experimental functional analysis for 10 target behaviors selected from Study 1. Correspondence between the experimental functional analyses was 60% with the FAST and the MAS, 50% with the QABF.

Nixon's Program of Wage and Price Controls

Description: This investigation analyzes the government's current attempt at wage and price controls; and covers only Phases I, II, and III--with primary emphasis on Phase II. The sources of data used are current periodicals. The study is composed of five major chapters. Chapter I presents a brief summary of prior attempts at wage and price controls, both in this country and abroad, plus-a thumbnail sketch of economic conditions in this country preceding Phase I. The next three chapters deal with the three phases themselves. In each case, the guidelines are presented along with the mechanism of execution, enforcement, and actual cases of operation. As the overall program is still in operation, final conclusions are not appropriate at this time.

The Effect of a Change Facilitator on Project-Based Learning Curriculum and Design

Description: This study sought to understand concerns and levels of use of a group of teachers in the process of developing a project-based learning (PBL) program, and the effect of a change facilitator on these processes. The research was guided by the following research questions: One, what are the concerns of teachers regarding the planning of a PBL curriculum? Two, what are the levels of use of teachers in the process of planning the PBL curriculum? Three, how does a change facilitator affect the process of change in the planning of a PBL curriculum? The population of this study consisted of seven subject area high school teachers and one district level administrative staff member. This study used the concerns-based adoption model (CBAM) to study the PBL innovation. CBAM is a conceptual framework that describes, explains, and predicts teachers' concerns and behaviors throughout the change process in education. In this study, the teachers progressed through the levels of use on a timeline at a rate that was much more rapid that what is typical for implementation of an innovation in an educational setting. This rapid progression was the function of the teacher population studied and the change facilitator that led the PBL curriculum design process. With the leadership of the change facilitator, the goals of the PBL curriculum innovation were realized, and the team created a PBL curriculum with multidisciplinary PBL products that could be implemented after the development phase.

The Characteristics of Play Therapy Sessions with Children: A Preliminary Investigation

Description: This research study investigated various characteristics of children in play therapy and their play behaviors during sessions. Specifically, this research investigated how gender, age, ethnicity, household and presenting problem of children impacted the play therapy process. Thirty-two cases of children who received ten or more sessions of play therapy at the Child and Family Resource Clinic, University of North Texas, Denton, Texas between the years of 1998-2002 and met specified criteria were coded and entered into a computer spreadsheet for analysis. The background information provided by the parent/guardian of each child was analyzed using various measures of central tendency to summarize and describe the data sets. The session summary data completed by play therapists at the CFRC was examined using analysis of variance and multivariate analysis of variance. Analysis of variance and multivariate analysis of variance revealed statistical significance between the following variables: a) males and use of dolls (.01), animals (.007) and weapons (.014), and males and expression of happy (.048), confident (.042) curious (.007) and flat (.029) during play therapy sessions; b) young children and use of vehicles (.050) during play therapy sessions; c) Caucasian children and expression of happy (.011), and confident (.008) during play therapy sessions; d) children residing in single parent households and use of hammer (.049) and puppets (.048) during play therapy sessions; and e) a variety of presenting problems and toy use/play behavior, feelings expressed and themes played out during play therapy sessions. Frequency of toy use and emotional expression were also investigated as well as session peaks of toy use, emotions expressed and themes. Analysis revealed that the toys used most often during play therapy sessions included the following categories: sandbox, easel/paints, dolls, weapons, crafts and money. Feelings expressed most often in play therapy sessions included excited, pleased, focused, interested, proud, curious, ...

An Annotated Bibliography of Selected Chamber Music For Saxophone, Winds and Percussion with Analyses Of Danses Exotiques by Jean Françaix, and Nonet by Fisher Tull

Description: An expansive repertoire of original chamber works is available for ensembles comprised of saxophone, wind and percussion instruments. Many musicians, including saxophonists and conductors, are unaware of this enormous body of literature. This produces a compelling need for sources of identification available to conductors, performers and teachers. This study begins to provide such a source through the presentation of selected works and the accompanying annotated bibliography. The lack of awareness of available scores for chamber music with saxophone, winds and percussion among conductors and many performers often contributes to the absence of these works in concert halls. The objective of this lecture-recital document is to make available a tool that includes only original works for the saxophone in a variety of chamber ensemble settings. The nature of this study will be descriptive. The literature chosen for this project reveals varying levels of performance difficulty, compositional techniques, form, and instrumentation. Chosen works employ an ensemble size that requires a conductor or are more successfully performed with a conductor. Selected compositions are illustrated in which the saxophone is identified as a vital ingredient in an already existing repertoire of serious chamber literature. Works in this study include original compositions using from seven to seventeen musicians. Some of the works discussed in this study include double bass and piano. Chapters include information on the Parameters of Study (Introduction, Historical Perspective, Sources, Criteria, Selection of Works for Analysis), composer Jean Françaix, a Historical Overview and Detailed Study of Danses Exotiques, composer Fisher Tull, a Historical Overview and Detailed Study of Nonet and an Annotated Bibliography of compositions matching the established criteria. Appendices include List of Works of Fisher Tull and Jean Françaix.

A status and vision investigation of US university piano pedagogy programs.

Description: The two major research questions were: “What is the current status of 20 prominent piano pedagogy programs?” and “what is the vision of an ideal future piano pedagogy program from the perspective of 20 piano pedagogy leaders?” Subjects were the leaders of the top 20 US university piano pedagogy programs. A survey study with interview questions was used as the instrument for the study. The results showed that faculty, curriculum, and teacher training were three top factors that contributed to the quality of the programs. Most interviewed subjects held a doctoral degree in music. The curricular content and degree options were diverse across the selected programs. The content of teacher training included private and group teaching. The perceived best qualifications of a piano pedagogy instructor were to have a balanced education. Most programs had small or little to no budget, however, the preparatory program was perceived to be an enhancement to teacher training program finances. The greatest challenges were faculty acquisition and financial limitations. Gaining more money was the most common improvement priority for programs. To envision an ideal future piano pedagogy program, most leaders stated that an ideal program should contain encourage: (1) collaborating with other divisions' faculty members for developing a diverse curriculum, (2) providing multiple types of teacher training, (3) offering knowledge that is highly pertinent to students' future careers, (4) continually adjusting topics in the curriculum, and (5) utilizing all the possible resources to establish up-to-date facilities. The chief obstacle was a lack of money. However, finding a major donor, and developing a preparatory program to generate money may help to overcome the obstacles. Having administrators with positive attitudes toward pedagogy could help programs to gain more resources. Encouraging students to participate in workshops and conferences could enrich the training. Several recommendations may help emerging pedagogy ...

Learning From Each Other: Narrative Explorations of Art Museum Self-guided Materials

Description: By engaging in collaborative arts-based and arts-informed narrative inquiry with my six-year-old daughter, we explored self-guided materials in art museums in the North Texas area. Though the field of art museum education is becoming increasingly participatory, most academic research related to self-guided materials has fallen short of exploring visitors' experiences with these materials. Furthermore, the perspectives of children have been long overlooked in academic and, at times, institutional research about family experiences in museums. Over the course of nine months, my daughter and I visited art museums and engaged with their self-guided materials, ranging from audio tours to interactive galleries. During this time we created collaborative works of art based on our experiences, which acted as both data collection and analysis in preparation for writing narratives. Our narrative explorations allowed us each to better understand our collective experiences. Though this research specifically targets self-guided materials in art museums, any educator interested in intergenerational or collaborative family learning may find both our methodologies and our conclusions to be helpful in better understanding how narratives are essential to this type of learning.

Theories Contrasted: Rudy's Variability in the Associative Process (V.A.P.) and Martin's Encoding Variability

Description: A paired-associate list of three-word stimuli and one-word responses comprised the first list of an A-B, A-Br paradigm. Each of the three words from the first-list three-word stimuli was singly re-paired with first-list responses to make up three of the second-list conditions. The fourth second-list condition used the first-list stimuli plus re-paired first-list responses. Results obtained were that: (a) nine of the sixteen subjects spontaneously shifted encoding cues from first to second lists, (b) evidence of significantly greater negative transfer occurred only in the A-B, A1 2 3-Br condition, and (c) although not attaining significance level, across all A -Br conditions there were more errors on second-list learning for those not shifting encoding cues from first to second list. For those who did shift, performance was only slightly lower than the A-B, C-B control condition. Neither the encoding variability nor the associative variability theory was entirely supported. A gestalt interpretation was suggested.

Op. 34: Evidence of Arnold Schoenberg's Musikalische Gedanke

Description: Composition for Arnold Schoenberg is a comprehensible presentation of a musical idea (musikalische Gedanke); the totality of a piece represents the idea. For tonal works, he defines Gedanke as a process of resolving the "tonal relation" or "tonal problem." Contrary to the numerous tonal examples illustrating the notion of Gedanke, Schoenberg hardly expounds on the Gedanke principle for his atonal and twelve-tone repertoires. This study reevaluates Schoenberg's compositional philosophy and aesthetics including Gedanke, comprehensibility, Grundgestalt, and developing variation in light of his compositional practices in Begleitungsmusik zu einer Lichtspielszene, Op. 34. Although Schoenberg denies the existence of a tonal problem and hierarchy among pitches in twelve-tone compositions, the registral placement found in Op. 34 indicates certain functionality assigned to each pitch-class, producing a sense of "departure and return." The approach here elucidates the "idea" of Op. 34, in which the large-scale formal organization unfolds through contextually emphasized tonal relations. This study also explores Schoenberg's concept of the multi-dimensional presentation of a musical idea. Even though Schoenberg's discussion of musical coherence is usually limited to the immediate musical surface, I believe that he was also aware of an extended realization of foreground motives in the sense of Heinrich Schenker's "concealed motivic repetition." This analysis of Op. 34 demonstrates how the enlargement of a surface motive facilitates an understanding of the relation between the parts and the whole, which is perceived as the totality of Gedanke.
