<p>This essay examines a small selection of Swedish newsreel and documentary short films, primarily travelogues, produced shortly before and after the second world war. The general aim is to expose differences in the representation of “The Other” and the “ethnic Swede” by applying a critical discourse analysis. The purpose is to illuminate how the material positions the latter as the norm and then contextualize this with xenophobic currents that had developed up until the middle of the twentieth century. Theoretical and methodological framework is drawn from the field of cultural studies as well as the nonfiction film. The analysis shows that the Swedish newsreel and travelogue indeed, to a high degree, possessed these currents even though part of them, mainly the anti-Semitic ideas, seems to relapse after the Holocaust.</p>

This study explored the relationship between how students are taught to write in first-year English composition classes and what they are expected to read as part of the general education requirements at a publically-funded large university in the southeast (PLUS), and then to determine whether a gap exists. If a gap is found to exist between the preparation of students and their ability to read material that has been assigned by the teaching faculty, these students are less likely to be considered information literate by any rubric. This study uses a mixed-methods approach. Content analysis is employed to examine the assigned readings students encounter, and interviews are conducted to explore how students make sense of the academic writings assigned in general education classes. Research questions included (1) What are the overall structures of both (a) instruction composition and (b) scholarly journal articles assigned for reading in subsequent general education classes in the disciplines of psychology and history at PLUS? (2) How can these structures be identified? (3) What are the top-level structural patterns of composition within these two academic disciplines and how do they differ? and (4) Do these differences create contradictions in how students are taught to write in freshmen composition courses and the composition of the journal articles they are expected to read in their required general education classes? Thirty-one texts taken from general education syllabi were analyzed for incidence and placement of specific structural elements such as topic sentences and signal words. This study also explored perceptions of these differences from the standpoint of college students. Interviews of twenty-two students were conducted using Dervin’s Sense Making Methodology. These interviews were analyzed in terms of situations, gaps, bridges, outcomes, as well as thematic concepts that consistently arose during the interviews. Significant differences existed between readings from English Composition classes and assigned scholarly journal articles in history and psychology in incidence and placement of topic sentences, use of signal words or phrases, and readability. In addition, thematic analysis of the interviews of students found that they experienced gaps between their expectations of text composition and their experience reading assigned journal articles.

The ISI provides librarians with tools such as the Journal Citation Reports (JCR) and the institution specific Local Journal Utilization Report (LJUR) to aid in the management of serials collections. These tools enable librarians to respond quickly to changes in publishing practices and purchasing options. While available literature often criticizes ISI data, few studies provide concrete recommendations for improvement. This study explores two extensions to LJUR: (1) adding citation date and (2) creating institution specific impact factors. In addition, I explore the degree to which self-citations influence the ISI impact factor. Publication and citation calculations are made for three prominent southern universities’ research chemists using a corpus of full text articles drawn from 27 American Chemical Society (ACS) journals and stored in an Oracle database. The ACS research corpus impact factor simulation and ACS research corpus self-citation omission impact factor are also created and compared with current JCR data.

The journal cited frequency is usually an index to weigh an academic research achievement and may provide useful information for the academic society. However, it is spectulated that it may be influenced by factors such as the citing frequencies of other journals, the price of the journal and so on. In this work, as an initial attempt we will investigate the correlation between the citing frequency and cited frequency in the same journal. The data is taken the JCR (Journal Citation Reports) annually published by ISI (Institute for Scientific Information) to understand the relationship between citing and cited patterns. Moreover, Impact Factor from the JCR has also been used as a basis of ranking, we will discuss about the variation in journal ranking in all fields based on Markov chain modeling. The ranking based on a modified impact factor will be used to compare with that by the original impact factor provided by the JCR.

This dissertation deals with three research topics; i) the catcher bearings life prediction method, ii) the Morton effect, and iii) the two dimensional modified Reynolds equation. Firstly, catcher bearings (CB) are an essential component for rotating machine with active magnetic bearings (AMBs) suspensions. The CB's role is to protect the magnetic bearing and other close clearance component in the event of an AMB failure. The contact load, the Hertzian stress, and the sub/surface shear stress between rotor, races, and balls are calculated, using a nonlinear ball bearing model with thermal growth, during the rotor drop event. Fatigue life of the CB in terms of the number of drop occurrences prior to failure is calculated by applying the Rainflow Counting Algorithm to the sub/surface shear stress-time history. Numerical simulations including high fidelity bearing models and a Timoshenko beam finite element rotor model show that CB life is dramatically reduced when high-speed backward whirl occurs. Secondly, the theoretical models and simulation results about the synchronous thermal instability phenomenon known as Morton Effect is presented in this dissertation. A transient analysis of the rotor supported by tilting pad journal bearing is performed to obtain asymmetric temperature distribution of the journal by solving variable viscosity Reynolds equation, energy equation, heat conduction equation, and equations of motion for rotor. The tilting pad bearing is fully nonlinear model. In addition, thermal mode approach and staggered integration scheme are utilized in order to reduce computation time. The simulation results indicate that the temperature of the journal varies sinusoidally along the circumferential direction and linearly across the diameter, and the vibration envelope increased and decreased, which considers as a limit cycle that is stable oscillation of the envelope of the amplitude of synchronous vibration. Thirdly, the Reynolds equation plays an important role to predict pressure distribution in the fluid film for the fluid film bearing analysis. One of the assumptions on the Reynolds equation is that the viscosity is independent of pressure. This assumption is still valid for most fluid film bearing applications, in which the maximum pressure is less than 1 GPa. In elastohydrodynamic lubrication (EHL) which the lubricant is subjected to extremely high pressure, however, the pressure independent viscosity assumption should be reconsidered. With considering pressure-dependent viscosity, the 2D modified Reynolds equation is derived in this study. The solutions of 2D modified Reynolds equation is compared with that of the classical Reynolds equation for the plain journal bearing and ball bearing cases. The pressure distribution obtained from modified equation is slightly higher pressures than the classical Reynolds equations. / PDF file replaced 10-21-2012 at the request of the Thesis Office.

Aim: This paper is a report on a study that explored the professional development of intensive care unit nurses in journal clubs. Background: Evidence-based practice is important in nursing care (Krom, Batten, & Bautista, 2010). However few nurses feel comfortable using evidence to guide their practice (Pravikoff, Tanner, & Pierce, 2005). Journal clubs are a way to establish science as conversation (Wright, 2004) and foster knowledge translation for evidence-based nursing practice (Goodfellow, 2004). Methods: Monthly journal club meetings were held with the participation of a total of 71 healthcare professionals (65 nurses, 2 physicians, 2 pharmacists, 1 physiotherapist, and 1 respiratory therapist), who worked in two intensive care units of an Ontario hospital. After six months of meetings, 21 individual interviews were conducted with nurses, physicians, pharmacists, and nurse educators. Additional data collection included two focus groups, surveys, a review of staff meeting minutes, and researcher field notes. Findings: Journal clubs provided nurses with incentive to read research articles, improved nurses’ confidence in reading research, created a community of peers who worked collaboratively to improve clinical practice, provided a structure for nurses to reflect-on-practice, and led to reported changes in clinical practice. However, the data suggests that any gains in competence of nurses with the critical appraisal of research articles were probably modest. Barriers to participating in journal clubs and evidence-based practice are also identified. Conclusion: Journal clubs can foster knowledge translation and evidence-based practice through creating a community of practice and by providing nurses with motivation, structure, and confidence to read research articles. However, nurses reported a lack of critical appraisal skills and uncertainty about how to implement evidence into practice. Journal clubs may have a greater impact when implemented alongside other knowledge translation strategies such as working with clinical nurse specialists in order to enhance evidence-based practice.

A grounded theory methodology, justified by the logic of methodical hermeneutics, was employed to guide both the collection and analysis of data produced from interviews with 11 psychotherapy clients who reported having unsuccessful experiences. Ultimately, I put forth the Clients Helical Path as a theoretical model grounded in clients' unsuccessful therapy experiences. The theory subsumes four subcategories: three cyclically-related subcategory processes (Embarking, Evaluating, and Ending), and a fourth category (Familiarity) that provides a temporal/experiential dimension. Clients embark upon a course of therapy with certain expectations; they later evaluate their experience on the basis of these expectations, and then end therapy when they adjudicate it as not sufficiently successful. Clients' familiarity with the enterprise of therapy is enhanced with each successive therapy experience, and this familiarity implicates clients' subsequent expectations, evaluations, and endings. The theory contextualizes clients experiences of unsuccessful therapy at the level of the individual, rather at the level of the course of therapy, thereby providing an understanding for how past therapy experiences influence future ones. This feature of the theory represents a significant departure from and contribution to the existing psychotherapy research literature. I discuss the unique nature and utility of the theory, its overlap with existing empirical findings, as well as its limitations. I suggest directions for future research, and I provide multiple credibility checks.
