Latino success stories in higher education: A qualitative study of recent graduates from a health science center.

This study used qualitative research, particularly life history analysis, to determine the personal pathways of success for Latino students who chose to enter a health science center for graduate study and who graduated. By giving voice to individual success stories of Latino students, some of the influences on the life pathways of these graduates were determined. For the purposes of this study, success was defined as graduation from a health science center with either a doctor of philosophy, doctor of public health or doctor of osteopathic medicine degree. Four research subjects agreed to participate in this study from a possible 11 students from the graduating class of 2004-2005 at this health science center. Data were gathered through multiple in-depth interviews of the students themselves over a period of no more than one month for each participant. Data were analyzed using the mind mapping technique and Padilla's unfolding matrix. Findings indicate that each participant traveled a different pathway to achieve educational success although similarities did exist across participants. The influences of family background, cultural background, educational background and personal perceptions and goals did affect the pathways of these four Latino graduates. While three of four participants indicated that family was the …

Hindrance of the Myosin Power Stroke Posed by the Proximity to the Troponin Complex Identified Using a Novel LRET Fluorescent Nanocircuit (open access)

Hindrance of the Myosin Power Stroke Posed by the Proximity to the Troponin Complex Identified Using a Novel LRET Fluorescent Nanocircuit

A novel luminescence resonance energy transfer (LRET) nanocircuit assay involving a donor and two acceptors in tandem was developed to study the dynamic interaction of skeletal muscle contraction proteins. The donor transmits energy relayed to the acceptors distinguishing myosin subfragment-1 (S1) lever arm orientations. The last acceptor allows the detection of S1's bound near or in between troponin complexes on the thin filament. Additionally, calcium related changes between troponin T and myosin were detected. Based on this data, the troponin complex situated every 7 actin monomers, hinders adjacently bound myosins to complete their power stroke; whereas myosins bound in between troponin complexes undergo complete power strokes.

Bridging the Gap: Finding a Valkyrie in a Riddle (open access)

Bridging the Gap: Finding a Valkyrie in a Riddle

While many riddles exist in the Anglo-Saxon Exeter Book containing female characters, both as actual human females and personified objects and aspects of nature, few scholars have discussed how the anthropomorphized “females” of the riddles challenge and broaden more conventional portrayals of what it meant to be “female” in Anglo-Saxon literature. True understanding of these riddles, however, comes only with this broader view of female, a view including a mixture of ferocity and nobility of purpose and character very reminiscent of the valkyrie (OE wælcyrige), a figure mentioned only slightly in Anglo-Saxon literature, but one who deserves more prominence, particularly when evaluating the riddles of the Exeter Book and two poems textually close to the riddles, The Wife's Lament and Wulf and Eadwacer, the only two poems with a female voice in the entire Old English corpus. Riddles represent culture from a unique angle. Because of their heavy dependence upon metaphor as a vehicle or disguise for the true subject of the riddle, the poet must employ a metaphor with similar characteristics to the true riddle subject, or the tenor of the riddle. As the riddle progresses, similarities between the vehicle and the tenor are listed for the reader. Within …

Interest Differentiation and Profile Elevation: Investigating Correlates of Depression, Confidence, and Vocational Identity (open access)

Interest Differentiation and Profile Elevation: Investigating Correlates of Depression, Confidence, and Vocational Identity

Using a correlational design, this study examined relationships among and between differentiation, profile elevation, gender and educational level (predictors) and depression, confidence, and vocational identity (criterion). Clients presenting for counseling services (n = 90) with a career concern at a large, metropolitan university were included in the study. Six assumptions were examined using three single hierarchical regression analyses to reveal relationships among and between variables. Two research assumptions were confirmed at the .05 level of significance. Bivariate correlations were computed to examine the structure coefficients. Beta weights and structure coefficients were examined to determine the relative contribution of the predictors in the regression model. Results indicated that differentiation, profile elevation, gender and educational level did not predict significant variance in depression and vocational identity. However, differentiation, profile elevation, and educational level did significantly predict confidence (p< .0001).

Dem Schwerte Muss Der Pflug Folgen: Űber-Peasants and National Socialist Settlements in the Occupied Eastern Territories during World War Two

German industrialization in the nineteenth century had brought forward a variety of conflicting ideas when it came to the agrarian community. One of them was the agrarian romantic movement led by Adam Műller, who feared the loss of the traditional German peasant. Műller influenced Reichdeutsche Richard Walther Darré, who argued that large cities were the downfall of the German people and that only a healthy peasant stock would be able to ‘save' Germany. Under Darré's definition, “Geopolitik” was the defense of the land, the defense with Pflug und Schwert (plow and sword) by Wehrbauern, an ‘Űberbauer-fusion' of soldier and peasant. In order to accomplish these goals, new settlements had to be established while moving from west to east. The specific focus of this study is on the original Hegewald resettlement ideas of Richard Walther Darré and how his philosophy was taken over by Himmler and fit into his personal needs and creed after 1941. It will shed some light on the interaction of Darré and Himmler and the notorious internal fights and power struggles between the various governmental agencies involved. The Ministry for Food and Agriculture under the leadership of Darré was systematically pushed into the background and all previous, …

An Analysis of Changes in Perceptions of Certified Athletic Trainers from 1996 to 2006 on the Women in Athletic Training Survey (open access)

An Analysis of Changes in Perceptions of Certified Athletic Trainers from 1996 to 2006 on the Women in Athletic Training Survey

This study investigates how perceptions vary in athletic trainers regarding issues pertaining to women in the profession. Subjects included 1500 male and 1500 female certified athletic trainers who responded to 44 demographic and perceptions survey items used to determine whether perceptions were different based on the respondent's gender. Results were compared to a previously disseminated survey in 1996 to also determine if perceptions had changed from 10 years earlier. Results regarding the presentation of awards and the attainment of leadership positions in the organization were also compared to actual data collected. The data suggested that males perceptions had not changed, but females' perceptions had changed, in that females perceived that opportunities had improved. Data regarding the number of females who had ascended to leadership positions or had received awards did not support these perceptions, however, and female athletic trainers continue to struggle to obtain equality in both of these areas. Additionally, homosocial reproduction continues to influence the decreased number of women who are hired into various jobs, or advance into leadership positions, maintaining patriarchy in the athletics arena and in the athletic training organizations. Results suggested that because athletic training has been dominated by men since its inception, patriarchy continues …

A Comparison of the Effects of Errorful and Errorless Teaching Methods on the Acquisition, Generalization, and Retention of Letter Sound Discriminations in Young Children. (open access)

A Comparison of the Effects of Errorful and Errorless Teaching Methods on the Acquisition, Generalization, and Retention of Letter Sound Discriminations in Young Children.

The present study compared the effects of an errorless stimulus shaping procedure to an errorful fluency based procedure for teaching difficult letter sound discriminations using a counterbalanced multielement experimental design. For 2 participants, letters fsteai were taught using the errorless procedure and letters bpdvou were taught using the errorful procedure. For the other 2 participants the conditions were reversed. All participants had considerably fewer errors and fewer trials to criterion with the errorless than with the errorful procedure. Tests of retention and generalization indicate that the errorful procedure generalized and was retained at a higher frequency than the errorless procedure. For 3 participants preference for the errorless procedure over the errorful procedure was demonstrated; whereas, the fourth participant demonstrated preference for the errorful procedure.

Distances (open access)

Distances

I provide in my preface a brief account of my development as a creative writer. Through this development I draw an analogy to the evolution of modern science by stating that my need for personal clarity is analogous to the charge for empirical clarity of modern science. Furthermore, I contrast the objectivism of modern science to the subjectivism of creative writing. The four short stories in my thesis range from a semi-autobiographical story, to two short stories that stem out further and further from the subjective origin of the first story. The story of greatest distance is “Fireflies,” which is not semi-autobiographical, but pure fiction. The final short story returns to the subjective origin of the first. The drive of Distances is thereby to create a sort parabola: a subjective, semi-autobiographical origin, to an objective, purely fictional crest, then a return to that subjective, semi-autobiographical origin. The entire collection is a holistic, ultimately subjective, and therefore personal experience; yet, through the use certain tropes,metaphors others can relate to, the stories are paradoxically sharable.

Metals in Chemistry and Biology: Computational Chemistry Studies

Numerous enzymatic reactions are controlled by the chemistry of metallic ions. This dissertation investigates the electronic properties of three transition metal (copper, chromium, and nickel) complexes and describes modeling studies performed on glutathione synthetase. (1) Copper nitrene complexes were computationally characterized, as these complexes have yet to be experimentally isolated. (2) Multireference calculations were carried out on a symmetric C2v chromium dimer derived from the crystal structure of the [(tBu3SiO)Cr(µ-OSitBu3)]2 complex. (3) The T-shaped geometry of a three-coordinate β-diketiminate nickel(I) complex with a CO ligand was compared and contrasted with isoelectronic and isosteric copper(II) complexes. (4) Glutathione synthetase (GS), an enzyme that belongs to the ATP-grasp superfamily, catalyzes the (Mg, ATP)-dependent biosynthesis of glutathione (GSH) from γ-glutamylcysteine and glycine. The free and reactant forms of human GS (wild-type and glycine mutants) were modeled computationally by employing molecular dynamics simulations, as these currently have not been structurally characterized.

Mama D's 2 Blocks: A Documentary Film

Mama D's 2 Blocks tells the story of a neighborhood home in New Orleans that was transformed into a distribution center and used to assist residents impacted by Hurricane Katrina's devastation in 2005. Mama D stayed at her home throughout the storm and remained there until the floodwaters had subsided. After the water had drained, socially minded youth from all over the country were drawn to Mama D's home and stayed there while supporting local renewal efforts. The film documents their joining together, without electricity or running water, and assisting in the rebuilding process undertaken by Mama D and other neighborhood residents. This film captures a community in action, how it survived, and the first steps taken towards the rebuilding of New Orleans.

Around the Fibonacci Numeration System

Let 1, 2, 3, 5, 8, … denote the Fibonacci sequence beginning with 1 and 2, and then setting each subsequent number to the sum of the two previous ones. Every positive integer n can be expressed as a sum of distinct Fibonacci numbers in one or more ways. Setting R(n) to be the number of ways n can be written as a sum of distinct Fibonacci numbers, we exhibit certain regularity properties of R(n), one of which is connected to the Euler φ-function. In addition, using a theorem of Fine and Wilf, we give a formula for R(n) in terms of binomial coefficients modulo two.

May 1856: Southern Reaction to Conflict in Kansas and Congress

This thesis examines southern reactions to events that occurred in May 1856: the outbreak of civil war in Kansas and the caning of Senator Charles Sumner of Massachusetts. I researched two newspapers from the upper South state of Virginia, the Richmond Enquirer and the Richmond Daily Whig, and two newspapers from the lower South state of Louisiana, the New Orleans Times-Picayune and the New Orleans Bee to determine the extent to which political party sentiment and/or geographic location affected southern opinion towards the two events. Political party ties influenced the material each newspaper printed. Each newspaper worried that these events endangered the Union. Some, however, believed the Union could be saved while others argued that it was only a matter of time before the South seceded.

Predicting Weight Loss in Post Surgical Laparoscopic Banding Patients (open access)

Predicting Weight Loss in Post Surgical Laparoscopic Banding Patients

The present study was a retrospective chart review (N=128) that investigated the efficacy of profiles derived from the three factors of the Eating Inventory® test (EI) - cognitive restraint, disinhibition, and hunger - to predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this population. Based on restraint theory, 7 profiles (high CR, super high CR, high D, super high D, high H, super high H, and null) were derived from the raw scores on the subscales of the EI and tested for weight loss predictive ability using direct logistic regression. Results were mixed with high CR, super high CR, and null profiles accurately predicting successful weight loss. Raw scores on the three factors (cognitive restraint, disinhibition, and hunger) were tested individually for predictive ability using direct logistic regression. Overall results indicated that the profile model accurately predicted more cases than the general factor model. This study significantly contributes to both the bariatric presurgical assessment literature and the restraint theory literature. Suggestions for future research are offered.

Culture and Mental Health Help-Seeking Attitudes in Mexico. (open access)

Culture and Mental Health Help-Seeking Attitudes in Mexico.

This study was designed to investigate 1) the cultural factors involved with Mexican citizens' attitudes toward seeking professional psychological help and 2) Mexican citizens' explanatory models of mental distress. Questionnaire data from 110 Mexican college students indicate that those who report a higher tolerance for stigma report lower endorsement of both the construct of personalismo and the machismo. Respondents who reported more interpersonal openness also reported a lower endorsement of the machismo construct. Participants from a large city reported significantly more stigma tolerance than those from a small city. Regression analyses reveal machismo as a significant predictor of stigma tolerance. Qualitative data was collected to provide additional in-depth information. Study results could be used to provide culturally appropriate mental health services.

Influence of parental swimming stamina on the cardiac and metabolic performance of larval zebrafish (Danio rerio). (open access)

Influence of parental swimming stamina on the cardiac and metabolic performance of larval zebrafish (Danio rerio).

Superior swimming stamina in adult fish is presumably passed on to their offspring, but the ontogeny of the appearance of superior stamina and the requisite enhanced cardio-respiratory support for locomotion in larval fishes has not been determined. Is the expression of the suite of parental traits enabling superior swimming stamina in their offspring dependent upon their achieving juvenile/adult morphology, or does it appear earlier in their larvae? To answer this, adults were classified into three groups based on swimming stamina, followed by measurement of length, mass, and width. Larval offspring from the two parental groups -high stamina larvae (HSL) and low stamina larvae (LSL)- were reared at 27°C in aerated water (21% O2). Routine and active heart rate, routine and active mass specific oxygen consumption were recorded through 21dpf, and cost of transport (COT) and factorial aerobic scope were derived from oxygen consumption measurements. Routine heart rate at 2dpf of LSL was 164 ± 1 b·min-1, compared to only 125 ± 2 b·min-1 for HSL. Routine heart rate subsequently peaked at 203 ± 1 b·min-1 at 5dpf in the HSL group, compared to 207 ± 1 b·min-1, at 4dpf in the LSP larvae. Active heart rate at 5 dpf of …

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

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 …

Personality and Rater Leniency: Comparison of Broad and Narrow Measures of Conscientiousness and Agreeableness (open access)

Personality and Rater Leniency: Comparison of Broad and Narrow Measures of Conscientiousness and Agreeableness

Performance appraisal ratings provide the basis for numerous employment decisions, including retention, promotion, and salary increases. Thus, understanding the factors affecting the accuracy of these ratings is important to organizations and employees. Leniency, one rater error, is a tendency to assign higher ratings in appraisal than is warranted by actual performance. The proposed study examined how personality factors Agreeableness and Conscientiousness relate to rater leniency. The ability of narrower facets of personality to account for more variance in rater leniency than will the broad factors was also examined. The study used undergraduates' (n = 226) evaluations of instructor performance to test the study's hypotheses. In addition to personality variables, students' social desirability tendency and attitudes toward instructor were predicted to be related to rater leniency. Partial support for the study's hypotheses were found. The Agreeableness factor and three of the corresponding facets (Trust, Altruism and Tender-Mindedness) were positively related to rater leniency as predicted. The hypotheses that the Conscientiousness factor and three of the corresponding facets (Order, Dutifulness, and Deliberation) would be negatively related to rater leniency were not supported. In the current sample the single narrow facet Altruism accounted for more variance in rater leniency than the broad Agreeableness …

Exploring Fear and Freud's The Uncanny

Fear is one of the oldest and most basic of human emotions. In this thesis, I will explore the topic of fear in relation to literature, both a staple of the horror genre as well as a device in literary works, as well as in my own writings. In addition, I will use Sigmund Freud's theory of the “uncanny” as a possible device to examine the complexities of fear and its effects both on the mind and body through the medium of literature, and, more specifically, where and how these notions are used within my own short stories. By exploring how and why certain fears are generated, we may be able to better examine our own reactions in this regard.

Faculty training and professional development programs designed to impact Web-based instruction in higher education: A faculty perspective.

Web-based instruction has fast become a common component of higher education. Although such instruction began as a supplemental form of interaction, it has now become a basic aspect of many college courses and degree programs. If teacher and student are not in the same place at the same time, it becomes necessary to introduce a communications medium that will not only deliver information but also provide a channel of interaction between them. This study focused on faculty training and development programs designed to impact Web-based instruction in higher education at the five largest state-funded universities in Texas within a college of education. The instrument used in this study was developed by the research to collect data relating to faculty perception of training and development opportunities available to them at their institutions, perceptions of administrative support, and technical support. The objective was to determine if there was a relationship between these items listed above and faculty members' levels of confidence and perceptions of effectiveness when teach Web-based courses.

Assessment of Sediment Runoff from Natural Gas Well Development Sites. (open access)

Assessment of Sediment Runoff from Natural Gas Well Development Sites.

Storm water sediment runoff from disturbed landscapes has the potential to impair aquatic environments. Small construction sites of 1-5 acres in the United States are currently regulated by the United States Environmental Protection Agency to minimize storm water runoff damages to the environment. Gas well construction sites are similar to other construction sites in how the landscape is altered, but are not similarly regulated. This study identified sediment runoff from gas well development sites by collecting it in traps and weirs, and by measuring sediment debris lobes. Sediment primarily consisted of silt and clay sized particles. Sediments from two gas well sites formed five debris lobes that ranged in size from 325 to 3,290 square feet. Sediment loadings estimated from the debris lobes averaged 57.1 tons per year/acre. Future studies should focus on further quantification of sediment movement off of gas well sites and identify effective erosion control methods.

Coyote Ugly Librarian: A Participant Observer Examination of Lnowledge Construction in Reality TV.

Reality TV is the most popular genre of television programming today. The number of reality television shows has grown exponentially over the last fifteen years since the premier of The Real World in 1992. Although reality TV uses styles similar to those used in documentary film, the “reality” of the shows is questioned by critics and viewers alike. The current study focuses on the “reality” that is presented to viewers and how that “reality” is created and may differ from what the participants of the shows experience. I appeared on two reality shows, Faking It and That's Clever, and learned a great deal as a participant observer. Within the study, I outline my experience and demonstrate how editing changed the reality I experienced into what was presented to the viewers. O'Connor's (1996) representation context web serves as a model for the realities created through reality television. People derive various benefits from watching reality TV. Besides the obvious entertainment value of reality TV, viewers also gather information via this type of programming. Viewers want to see real people on television reacting to unusual circumstances without the use of scripts. By surveying reality TV show viewers and participants, this study gives insight …
