Show moreThe prevalence and importance of humor in the workplace has been well-documented over the past several decades, with research consistently revealing its significant impact on employee well-being and effectiveness. During this same time period, organizations worldwide have begun embracing team-based work designs as a means for achieving success. As a result, the degree to which employees are engaging in both frequent and intensive interactions with their coworkers is rapidly increasing. Despite these trends, little research has been dedicated to investigating the ways in which employees' well-being and effectiveness are influenced by the humor of their coworkers or the ways in which employees' own humor interacts with that of their coworkers to determine these outcomes. The current study answered the need for such research by investigating the impact of coworker-employee humor interactions on employee strain and performance using a sample of undergraduate-level students engaged in a high-fidelity work simulation. In the current study, coworker humor was experimentally manipulated by pairing each participant with a study confederate who was trained to act as either a non-humorous coworker or a humorous coworker throughout the duration of the work simulation. Results of a pilot study provided empirical evidence supporting the validity of this manipulation; showing that participants' paired with a humorous confederate coworker rated their coworker significantly higher on positive humor, but no different on negative humor, than participants' paired with a non-humorous confederate coworker. Based on theory and prior findings drawn from multiple streams of science, it was expected that positive coworker humor would have a significant impact on employees' strain and performance, but that the nature of its influence on these outcomes would be contingent upon employees' own dispositional humor. Specifically, it was hypothesized that employees paired with humorous coworkers would experience a lesser degree of perceived, affective, cognitive, and physical strain than employees paired with non-humorous coworkers if their own sense of humor was high but a greater degree of perceived, affective, cognitive, and physical strain than employees paired with non-humorous coworkers if their own sense of humor was low. In addition, it was expected that employees paired with humorous coworkers would demonstrate a higher level of interpersonal and task performance than employees paired with non-humorous coworkers if their own sense of humor was high but a lower level of interpersonal and task performance than employees paired with non-humorous coworkers if their own sense of humor was low. Finally, it was hypothesized that employees' strain would partially mediate the effects of coworker-employee humor interactions on employee performance.In support of these hypotheses, analyses revealed that several indicators of employees' perceived, affective, cognitive, and physical strain were in fact each significantly influenced by interactions between employees' own humor and that of their coworkers. Specifically, high sense of humor employees who worked with a humorous coworker experienced a lesser degree of perceived, affective, cognitive, and physical strain than did those who worked with a non-humorous coworker. This was evidenced by their lower self-reported perceived strain (an indicator of perceived strain), higher state-level positive affect and lower state-level negative affect (indicators of affective strain), higher anagram task performance and lower perceived task difficulty (indicators of cognitive strain), as well as their lower systolic blood pressure and lower state-level somatic anxiety (indicators of physical strain). In contrast, low sense of humor employees who worked with a humorous coworker experienced a greater degree of perceived, affective, cognitive, and physical strain than did those who worked with a non-humorous coworker. This was evidenced by their higher self-reported perceived strain, lower state-level positive affect and higher state-level negative affect, lower anagram task performance and higher perceived task difficulty, as well as their higher systolic blood pressure and higher state-level somatic anxiety. Consistent with expectations, results revealed that the degree to which employees experienced job strain typically varied based on the degree to which there was a match between employee sense of humor and coworker positive humor levels. Similar levels of coworker and employee humor generally resulted in relatively low levels of employee strain whereas dissimilar levels of coworker and employee humor most often resulted in relatively high levels of employee strain. Contrary to expectations, however, coworkers' positive humor and employees' sense of humor did not interact to predict employees' interpersonal or task performance. Instead, positive coworker humor had a significant positive main effect on both forms of employee performance. Although these findings are consistent with the study hypotheses in that positive coworker humor was expected to enhance high sense of humor employees' performance, they run counter to the expectation that positive coworker humor would hinder low sense of humor employees' performance. Because the interaction between coworker humor and employee humor was not a significant predictor of either type of employee performance, analyses were not conducted to test for mediated moderation.Findings from the current study offer a number of contributions to organizational science and, in addition, hold several implications for practice. Specifically, these results have relevance for and greatly expand the workplace humor, individual differences, PE fit, occupational health, and workgroup/team composition literatures. In addition, results contribute to the literature by elucidating the need for future research dedicated to exploring the direct and interactive effects of coworker characteristics, including humor, on employee well-being and effectiveness. Finally, results of this study serve to inform researchers and practitioners in matters related to several critical human resource functions, including matters in personnel selection, placement, and training, as well as in workgroup/team composition.

Show moreThe purpose of this study is to determine the possibility of the occupational interview utilizing tests that prove to be bias towards one particular race or another. This study is a pilot study and represents the first step in developing a more extensive research design to examine testing bias within the occupational employment interview setting. Ten black students and ten white students are asked to complete two types of occupational interview samples. Those samples are then reviewed by two black hiring managers and two white hiring managers. The results are examined to determine if one test had a greater impact on the manager's hiring decisions. The findings indicate that when compared to the unstructured interview, the structured interview was associated with less bias in the hiring selection. From the data reviewed, possible limitations and future research was discussed.

Show moreThe primary purposes of this study were (a) to investigate the relationship between counseling interns' site supervisors' experience and training in supervision and their own levels of ego development and (b) to investigate the relationship between supervisors' levels of ego development and the ego functioning and occupational stress of their intern-supervisees. The theoretical framework for this investigation included cognitive developmental models of supervision (e.g., Blocher, 1983; Stoltenberg, 1981), ego development (Loevinger, 1976, 1997) and the Person-Environment Fit theory of occupational stress (French, Rogers, & Cobb, 1974). The findings of this study contribute to an understanding of (a) the levels of ego development and post-degree clinical supervision experiences of internship site supervisors in different areas of counseling specialty; (b) the relationship between social-cognitive developmental levels and levels of perceived occupational stress in counseling interns; and (c) cognitive development theory and counseling supervision. Ninety-six counseling internship students in three master's level counseling programs accredited by the Council for Accreditation for Counseling and Related Educational Programs (CACREP) in Central Florida as well as 58 (73% response rate) of their internship site supervisors participated in the study. The site supervisors completed the Supervisors Experience Questionnaire (Walter, 2008) and the Washington University Sentence Completion Test--Form 81 (WUSCT; Hy & Loevinger, 1996). The participating counseling internship students completed a demographics questionnaire, the WUSCT--Form 81, and the Occupational Stress Inventory – Revised (OSI-R; Osipow, 1998). The statistical procedures used to analyze the data included chi-square, ANOVA, simultaneous multiple regression, and MANOVA procedures. The primary research hypotheses for the study were (1) that formal training in supervision and participation in post-graduate clinical supervision would predict supervisor ego development and (2) that supervisor ego development would predict supervisee ego development and occupational stress levels; these were not supported for these data. However, the results identified statistically significant relationships between supervisor participation in post-graduate clinical supervision and area of counseling specialty, with school counselor supervisors less likely to have participated in supervision than other supervisors. Additionally, the findings identified a negative correlation between interns' levels of perceived occupational stress and their ego development levels (14.6% of the variance explained), as well as a negative correlation between interns' levels of satisfaction with their internship site supervision and their levels of occupational stress (40% of the variance explained). The data from this investigation suggested that school counseling interns experienced higher levels of occupational stress due to occupational roles and lower levels of personal resources than interns in other counseling tracks, with the track accounting for 25.6% of the variance in the occupational stress levels. Implications for counseling supervisors and counselor educators are presented, along with areas for future investigation.

Show moreThe purpose of this research study was to examine the current use of clinical practice by full-time occupational therapy faculty members. Clinical practice, including faculty clinical practice and moonlighting were addressed. The seven research questions addressed were: (a) the perceived benefits of clinical practice as identified by occupational therapy faculty members; (b) the perceived barriers to clinical practice as identified by occupational therapy faculty; (c) if perceived benefits and barriers of clinical practice as identified by occupational therapy faculty differ as a function of their academic institution's Carnegie Classification (The Carnegie Foundation, 2000); (d) if perceived benefits and barriers of clinical practice differ among respondents according to tenure at the institution, tenure status, doctoral degree, rank, administrative duties, and gender; (e) the incidence of clinical practice in occupational therapy faculty members; (f) the relationship between participation in clinical practice and the Carnegie classification of the occupational therapy member's academic institution; (g) the characteristics (tenure status, doctoral degree, rank, administrative duties, and gender) of faculty members that participate in clinical practice either within or outside the faculty role; and (h) the characteristics of clinical practice as described by faculty members and how these differed if the clinical practice is conducted as part of the faculty role or outside the faculty role. Data were collected using an on-line survey that contained 43 questions designed to elicit information that addressed the research questions. The surveys were electronically mailed to the population of full-time occupational therapy faculty members obtained from a search of each academic program's website. A total of 224 responses were obtained. Descriptive statistics, ANOVAs, and Chi Square Test of Associations were used to analyze the data for the independent variables. The results showed that 60 respondents indicated that they participated in some type of faculty clinical practice as part of their faculty role. Most of this work was in a facility that was associated with the academic institution. Most of these respondents were not tenured, did not have a doctoral degree, and did not participate in administrative tasks. Most of these respondents worked in Doctoral-Extensive universities and held the Assistant Professor rank. Most worked two to four hours per week and did not receive release time or financial benefits. There were 99 respondents that indicated that they participated in moonlighting in a wide variety of settings. Most worked in their area of clinical expertise. Most of these respondents were not tenured and did not participate in administrative tasks. Only 37% had a doctoral degree. Over half had the rank of Assistant Professor. Almost 42% worked in Masters I academic institutions. Most worked less than 2 hours per week outside the faculty role and they received full financial benefits. The top three benefits for participating in clinical practice were to maintain clinical skills, enhance teaching, and improve credibility with students. The top three barriers for participating in clinical practice were teaching responsibilities, not a component in tenure decisions, and the additional responsibilities of practice. There were no statistically significant differences between the benefits or barriers to clinical practice and the Carnegie Classification of the respondent's academic institution. One ANOVA was significant between the barriers to clinical practice and if the respondent had a doctoral degree. There were no statistically significant differences between the benefits or barriers and tenure at the institution, the respondent's tenure status, the respondent's degree status, faculty rank, administrative duties, and gender except the respondents that had a doctoral degree had significantly higher barrier scores than those that did not have a doctoral degree. In general, less than five percent of the variance was explained by any of the independent variables. None of the Chi Square analyses revealed any significant differences between the academic institution's Carnegie Classification and if clinical practice was required, if a faculty participated in faculty clinical practice, or if a faculty member participated in moonlighting. In conclusion, although many faculty members recognize the benefits to participation in clinical practice, the barriers to clinical practice may be too great to outweigh the benefits for some faculty members. Most reported that clinical practice carried little weight in promotion or tenure decisions. In order for the scholarship of practice to flourish, active support from all academic institution administration is critical.

Show moreA significant body of writing and rhetoric research focuses on the literate practices that reflect or construct the professional self, particularly in disciplines that rely heavily on the use of forms to categorize or identify customers, clients, or patients. Many of these studies examine the influence of discipline-specific genres on the creation of a professional self for healthcare practitioners. Occupational therapy, a nearly 100-year-old yet little understood profession, is significantly different from many other healthcare disciplines, in part, because the genres used by occupational therapists reflect the profession's careful attention to the whole life of a patient. These genres are built around an understanding of a patient's occupation as the object of the profession's activity system. (")Occupation(") (commonly defined too narrowly by those outside of the profession as (")work(")), is, quite simply, anything that meaningfully and purposefully occupies a person's time. This broadly defined object invites an expansive professional vision that includes the patient's life and history outside of a diagnosis. This study presents the narratives of four occupational therapists and the literate activities that inform their practice. Their voices, as excerpted in this case study, join a strong, ongoing conversation in writing and rhetoric studies about the relationship between genre and identity. Using the lens of activity theory, this is one account of a healthcare profession that pays unusual attention to patients' whole lives through genres that mediate shared agency between the caregiver and patient. It is also, however, the story of the ways in which this identity, as a uniquely occupation-based discipline, becomes obscured as therapists translate their work to genres created and controlled by other, more powerful activity systems.

Show moreWithin the United States, more than a million jobs in science and engineering (S(&)E) are projected over the next few years; yet, the Nation lacks the workforce to meet these demands. Despite the need for a more diverse, qualified workforce, African Americans/Blacks remain disproportionately underrepresented in science occupations, science degree attainment, and in science postsecondary majors. The lack of science participation is reflective of how minority secondary students view science and science occupations as many consider the pursuit of a science career as unfavorable. Moreover, minority secondary students, who do choose to pursue science occupations, seem to possess inaccurate (or a lack of) occupational knowledge necessary to do so successfully. Therefore, an understanding of antecedents to career choice will assist educational professionals in addressing the underrepresentation of diverse populations, such as African Americans/Blacks, within the science workforce. The purpose of this study is to garner insight into the science occupational images, occupational and educational aspirations of African American/Black fourth and five grade students. Gottfredson's Theory of Circumscription and Compromise, in conjunction with extant empirical literature, serves as the foundation for the study's conceptual framework. A qualitative case study design was used. The qualitative data provided a contextual understanding of science occupational images, occupational and educational aspirations. Participant-produced drawings, questionnaires, and semi-structured interviews served as sources for data collection. Overall, participants lacked some occupational knowledge. Participants viewed scientists as mostly male and Black. Additionally, the occupation of scientist was perceived as a dangerous and of high status. Lastly, half of the participants expressed aspirations to be a scientist, while a majority expressed college educational aspirations.

Show moreThis study investigates the relationship between professional identity and professional status by exploring the quest for professionalization within technical communication. An established professional identity is crucial to an occupation's professionalization process, as it enables members of a given field to create a common sense of being and facilitates a recognizable personal and collective identity. Such recognition is vital to an occupation's rise to professional status, as it creates a distilled image of the ideal practitioner for outsiders and forms the basis upon which claims of expertise may be made. By constructing the meaning surrounding their profession, members are able to portray an image which designates their knowledge as a scarce expertise and their profession as the appropriate source for the services they provide.A lack of professional identity constitutes the primary factor hindering technical communication from realizing the professionalization process, as it prevents the formation of practitioners' common sense of being, promotes the absence of identifiability and precludes the possibility of recognition by larger society. Without an established professional identity, the field cannot formulate a culturally-relevant perception of its role, claim professional expertise or jurisdiction over their work, or achieve the social and cultural legitimacy necessary in order to increase its professional status. By implementing processes of occupational branding within the professional project, efforts involving the construction of collective professional identity will increase professional status by enabling a group's management of professional meaning, facilitating the creation of an occupational brand and assisting in value production.

Show moreThe purpose of this research was to determine the effect work environment has on occupational commitment and intent to leave the profession for bedside registered nurses. Subscales of autonomy, control over the practice setting, nurse-physician relationship, and organizational support were incorporated into the analysis to determine which aspect of work environment most directly effects occupational commitment and intent to leave the profession. The research was undertaken in order to help administrators determine the ways in which work environment can be improved upon in order to retain bedside registered nurses in the profession. An explanatory cross sectional survey was distributed to 259 direct care bedside registered nurses employed at a rural, system affiliated hospital in Central Florida. Human subject protection was assured through the University of Central Florida Institutional Review Board. A 77 item questionnaire containing 9 demographic questions, 57 questions from the Nursing Work Index- Revised (NWI-R), 8 questions from Blau's occupational commitment scale, and 3 questions from Blau's intent to leave scale was distributed to all direct care nurses. Subjects were also given the opportunity to complete 3 short answer questions. A 32.8 percent response rate was achieved for a total of 85 complete and usable surveys. Data analysis showed that the work environment is positively related to occupational commitment and negatively related to intent to leave. In addition each of the four subscales (autonomy, control over the practice setting, relationship with physicians, and organizational support) were also positively related to occupational commitment and negatively related to intent to leave the profession. Implications for organizations, public policy and future research are discussed.

Show moreThe purpose of this thesis was to examine the effects of occupational therapy rehabilitation on geriatric patients by reviewing studies conducted on motivation in occupational therapy. In occupational therapy it is important that you set goals for your patients (Creek & Lougher, 2008). It is also important to understand what motivates a patient to achieve those goals because goals and valued activities are intimately connected to motivation. Motivation deals with why we perform certain behaviors. It can predict physical performance and how well a person might recover from an illness and has been suggested to be predictive for rehabilitation success (Carlson, 1997). Because the geriatric population has more longevity, it is important to ensure that they receive the appropriate care necessary to improve and maintain their quality of life (Mason, 1994). After reviewing multiple studies the results reinforced the importance of motivation in occupational therapy treatment. Self-efficacy was found to highly influence a person�s motivation and was a recurring theme throughout this review (Peralta-Catipon & Hwang, 2011). One key to understanding and studying motivation in older adults was to identify what occupations matter to them (Teitelman, Raber, & Watts, 2010). It is important that occupational therapists understand how occupations become meaningful for the geriatric population as participation in those occupations plays an important role in promoting productive aging. When the occupational therapist was able to understand how occupations became meaningful to the patient, they were more equipped to help motivate the patient to participate in their rehabilitation (Janssen & Stube, 2013).

Show moreThis thesis intends to prove that Stephen V. Ash's model of occupation from his work, When the Yankees Came: Conflict and Chaos in the Occupied South, is applicable to St. Augustine's occupation experience in the Civil War. Three overarching themes in Ash's work are consistent with Civil War St. Augustine. First, that Union policy of conciliation towards southern civilians was abandoned after the first few months of occupation due to both non-violent and violent resistance from those civilians. Second, that Ash's "zones of occupation" of the occupied South, being garrisoned towns, no-man's-land, and the Confederate frontier apply to St. Augustine and the surrounding countryside. Finally, Ash's assertions that the southern community was changed by the war and Union occupation, is reflected in the massive demographic shifts that rocked St. Augustine from 1862 to 1865. This thesis will show that all three of Ash's themes apply to St. Augustine's Civil War occupation experience and confirms the author's generalizations about life in the occupied South.

Show moreThe purpose of the study is to explore the accuracy of the Input-Output model and its derivative, the Occupation-Based model in investigating the impacts of the 2007 economic crisis on the tourism-related industries and the local economy in the Metro Orlando Area, Florida. The 2007-2008 total visitor expenditure change is taken as an initial shock from the economic crisis on the region's tourism-related industries, and the total impacts are measured in terms of industry output (sales), employment and annual occupational wage. The estimation results are compared with the actual data to verify the accuracy of the modeling results. Paired-sample T tests are performed to determine whether the difference between the actual and estimated results are statistically significant or not. The findings suggest that the Input-Output model tends to overestimate the negative effects from the 2007 economic crisis in terms of output and employment, especially on the tourism-related industries. While the estimation results indicate the 2007 economic crisis greatly damaged the local tourism-related industries between 2007 and 2008, the actual data show that most of these industries experienced output and employment growth in that one year period. Moreover, the study findings also indicate that the Occupation-Based model has the tendency of overestimating the annual wage loss, especially for the occupations which take up large employment ratio in an industry. By investigating the local economic activities during the study period, this study made some explorative efforts in explaining such discrepancies. Theoretical and practical implications are then suggested

Show moreIntroduction: Lower extremity (LE) work-related musculoskeletal disorders (WMSDs) are known to occur with cumulative exposure to occupational and personal risks. The objective of this dissertation study was to find if creating a quantifiable risk detection model for the LE was feasible. The primary product of the literature review conducted for this study resulted in focusing the attention of the model development process onto creating the initial model of the LE for assessing knee disorder risk factors. Literature Review: LE occupational disorders affect numerous industries and thousands of people each year by affecting any one of the musculoskeletal systems deemed susceptible by the occupational and personal risk factors involved. Industries known to be affected tend to have labor intensive job descriptions. Some of the numerous industry examples include mining, manufacturing, firefighting, and carpet laying. Types of WMSDs noticed by the literature include bursitis, osteoarthritis, stress fractures, tissue inflammation, and nerve entrapment. In addition to the occupationally related disorders that may develop, occupationally related discomforts were also taken into consideration by this study. Generally, both the disorders and the discomforts can be traced to either a personal or occupational risk factor or both. Personal risk factors noted by the literature include a person's physical fitness and health history (such as past injuries). Meanwhile, occupational risks can be generalized to physical postures, activities, and even joint angles. Prevalence data over a three year interval (2003-2005) has found that LE WMSDs make up on average approximately 7.5% of all the WMSD cases reported to the US Occupational Safety and Health Administration (OSHA). When the literature is refined to the information pertaining to occupational knee disorders, the mean prevalence percentage of the same three year range is about 5%. Mean cost for knee injuries were found to be $18,495 (for the year between 2003 and 2004). Methodology: Developing a risk model for the knee meant using groups of subject matter experts for model development and task hazard analysis. Sample occupational risk data also needed to be gathered for each of a series of tasks so that the model could be validated. These sample data were collected from a sample aircraft assembly plant of a US aerospace manufacturer. Results: Based on the disorder and risk data found in the literature, a knee risk assessment model was developed to utilize observational, questionnaire, and direct measure data collection methods. The final version of this study's knee model has an inventory of 11 risk factors (8 occupational and 3 personal) each with varying degrees of risk exposure thresholds (e.g., high risk, moderate risk, or minimal risk). For the occupational risk assessment portion of the model, the results of task evaluations include both an occupational risk resultant score (risk score) and a task risk level (safe or hazardous). This set of results is also available for a cumulative (whole day) assessment. The personal risk assessment portion only produces a risk resultant score. Validation of the knee risk model reveals statistically (t (34) = 1.512, p = 0.156), that it is functioning as it should and can decide between hazardous and safe tasks. Additionally, the model is also capable of analyzing tasks as a series of cumulative daily events and providing an occupational and personal risk overview for individuals. Conclusion: While the model proved to be functional to the given sample site and hypothetical situations, further studies are needed outside of the aerospace manufacturing environment to continue testing both the model's validity and applicability to other industrial environments. The iterative adjustments generated for the occupational risk portion of the model (to reduce false positives and negatives) will need additional studies that will further evaluate professional human judgment of knee risk against this model's results. Future investigations must also make subject matter experts aware of the minimal risk levels of this knee risk assessment model so that task observational results are equally comparable. Additional studies are moreover needed to assess the intimate nature between variable interactions; especially multiple model defined minimal risks within a single task.

Show moreABSTRACTAmyloids are highly ordered cross-? sheet aggregates that are associated with many diseases such as Alzheimer's, type II diabetes and prion diseases. Recently a progress has been made in structure elucidation, environmental effects and thermodynamic properties of amyloid aggregates. However, detailed understanding of how mutation, packing polymorphism and small organic molecules influence amyloid structure and dynamics is still lacking. Atomistic modeling of these phenomena with molecular dynamics (MD) simulations holds a great promise to bridge this gap. This Thesis describes the results of MD simulations, which provide insight into the effects of mutation, packing polymorphism and molecular inhibitors on amyloid peptides aggregation. Chapter 1 discusses the structure of amyloid peptides, diseases associated with amyloid aggregation, mechanism of aggregation and strategies to treat amyloid diseases. Chapter 2 describes the basic principles of molecular dynamic simulation and methods of trajectory analysis used in the Thesis. Chapter 3 presents the results of the study of several all-atom molecular dynamics simulations with explicit solvent, starting from the crystalline fragments of two to ten monomers each. Three different hexapeptides and their analogs produced with single glycine replacement were investigated to study the structural stability, aggregation behavior and thermodynamics of the amyloid oligomers. Chapter 4 presents multiple molecular dynamics (MD) simulation of a pair polymorphic form of five short segments of amyloid peptide. Chapter 5 describes MD study of single-layer oligomers of the full-length insulin with a goal to identify the structural elements that are important for insulin amyloid stability, and to suggest single glycine mutants that may improve formulation. Chapter 6 presents the investigation of the mechanism of the interaction of polyphenols molecules with the protofibrils formed by an amyloidogenic hexapeptide fragment (VQIVYK) of Tau peptide by molecular dynamics simulations in explicit solvent. We analyzed the trajectories of the large (7(&)#215;4) aggregate with and without the polyphenols.Our MD simulations for both the short and full length amyloids revealed adding strands enhances the internal stability of wildtype aggregates. The degree of structural similarity between the oligomers in simulation and the fibril models constructed based on experimental data may explain why adding oligomers shortens the experimentally observed nucleation lag phase of amyloid aggregation. The MM-PBSA free energy calculation revealed nonpolar components of the free energy is more favorable while electrostatic solvation is unfavorable for the sheet to sheet interaction. This explains the acceleration of aggregation by adding nonpolar co-solvents (methanol, tri?uoroethanol, and hexa?uoroisopropanol). Free energy decomposition shows residues situated at the interface were found to make favorable contribution to the peptide -peptide association.The results from the simulations might provide both the valuable insight for amyloid aggregation as well as assist in inhibitor design efforts. First, the simulation of the single glycine mutants at the steric zipper of the short segments of various pathological peptides indicates the intersheet steric zipper is important for amyloid stability. Mutation of the side chains at the dry steric zipper disrupts the sheet to sheet packing, making the aggregation unstable. Thus, designing new peptidomimetic inhibitors able to prevent the fibril formation based on the steric zipper motif of the oligomers, similar to the ones examined in this study may become a viable therapeutic strategy. The various steric zipper microcrystal structures of short amyloid segments could be used as a template to design aggregation inhibitor that can block growth of the aggregates. Modification of the steric zipper structure (structure based design) with a single amino acid changes, shuffling the sequences, N- methylation of peptide amide bonds to suppress hydrogen bonding ability of NH groups or replacement with D amino acid sequence that interact with the parent steric zipper could be used in computational search for the new inhibitors. Second, the polyphenols were found to interact with performed oligomer through hydrogen bonding and induce conformational change creating an altered aggregate. The conformational change disrupts the intermolecular amyloid contact remodeling the amyloid aggregate. The recently reported microcrystal structure of short segments of amyloid peptides with small organic molecules could serve as a pharamcophore for virtual screening of aggregation inhibitor using combined docking and MD simulation with possible enhancement of lead enrichment. Finally, our MD simulation of short segments of amyloids with steric zipper polymorphism showed the stability depends on both sequence and packing arrangements. The hydrophilic polar GNNQQNY and NNQNTF with interface containing large polar and/or aromatic side chains (Q/N) are more stable than steric zipper interfaces made of small or hydrophobic residues (SSTNVG, VQIVYK, and MVGGVV). The larger sheet to sheet interface of the dry steric zipper through polar Q/N rich side chains was found to holds the sheets together better than non Q/N rich short amyloid segments. The packing polymorphism could influence the structure based design of aggregation inhibitor and a combination of different aggregation inhibitors might be required to bind to various morphologic forms of the amyloid peptides.

Show moreStudies of postwar Germany, from 1945-1955, have concentrated on the American influence as a military occupier, the development of German reconstruction and national identity, and memory of this period from the German perspective. Within the memory analyses, firsthand accounts have been analyzed to understand the perspectives of Germans living through the postwar period. Absent from this historiography is an account of American memories and firsthand perspectives of the occupation, particularly during the 1950-1955 period. This thesis employs oral histories of American veterans stationed in postwar Germany, American propaganda and popular cultural mediums during the early 1950s, and modern historiographical trends to provide an understanding of how Americans remember the German postwar decade. American veterans remembered this period, and their encounters with local Germans, as a positive experience. These positive memories were mediated by 1950s Cold War rhetoric and propaganda and were subsequently predicated upon the men's perspective as occupying soldiers. Their recollections align with American popular memory delineating the military occupation as ending in 1949 upon the creation of the Federal Republic of Germany, therefore overshadowing the 1950-1955 period of occupation. The ways in which Americans remember the postwar occupation in Germany, particularly from 1950-1955, inform broader memory and historical narrative trends of this era.

Show moreThe jaguar (Panthera onca) is a widely distributed large carnivore and the focal species of a range-wide connectivity initiative known as the jaguar conservation network (JCN). Comprised of ~83 Jaguar Conservation Units (JCUs) and ~75 corridors from northern Mexico to Argentina, the JCN functions as a conduit for jaguar movement and gene flow. Key linkages in the network are imperiled by human population growth, large-scale agriculture, highway expansion, and other infrastructural development. Labeled (")corridors of concern,(") these vulnerable linkages are imperative to the maintenance of connectivity and genetic diversity throughout jaguar distribution. I take a multi-faceted approach to analyze conservation issues and identify potential solutions in three of the most vulnerable connections of the JCN. I estimate densities and assess local residents' perceptions of jaguars in a fragmented JCU in western Mexico, analyze 3 years of data from 275 camera-trap sites to evaluate jaguar habitat use in a corridor of concern in Colombia, and quantify the umbrella value of jaguars for endemic herpetofauna in Nuclear Central America, a ~ 370,000 km(&)#178; sub-region of the Mesoamerican biodiversity hotspot. My research produces the first jaguar density estimate in a JCU containing human population densities (>)50 people/km2 and provides the strongest support for jaguar association with wetlands collected to date. In Nuclear Central America, one of the most important yet vulnerable areas of the JCN, I demonstrate the umbrella value of this wide-ranging felid. I conclude with a discussion on the need to reevaluate extirpation thresholds of jaguars in human-use landscapes, to direct more research on wetlands as keystone habitats for jaguars, and to further assess the utility of umbrella analyses using jaguars as focal species to support holistic conservation planning.
