AbstractPerforming publicly has become increasingly important in a variety of professions. This condition is associated with performance anxiety in almost all performers. Whereas some performers successfully cope with this anxiety, for others it represents a major problem and even threatens their career. Musicians and especially music students were shown to be particularly affected by performance anxiety.Therefore, the goal of this PhD thesis was to gain a better understanding of performance anxiety in university music students. More precisely, the first part of this thesis aimed at increasing knowledge on the occurrence, the experience, and the management of performance anxiety (Article 1). The second part aimed at investigating the hypothesis that there is an underlying hyperventilation problem in musicians with a high level of anxiety before a performance. This hypothesis was addressed in two ways: firstly, by investigating the association between the negative affective dimension of music performance anxiety (MPA) and self-perceived physiological symptoms that are known to co-occur with hyperventilation (Article 2) and secondly, by analyzing this association on the physiological level before a private (audience-free) and a public performance (Article 3). Article 4 places some key variables of Article 3 in a larger context by jointly analyzing the phases before, during, and after performing.The main results of the self-report data show (a) that stage fright is experienced as a problem by one-third of the surveyed students, (b) that the students express a considerable need for more help to better cope with it, and (c) that there is a positive association between negative feelings of MPA and the self-reported hyperventilation complaints before performing. This latter finding was confirmed on the physiological level in a tendency of particularly high performance-anxious musicians to hyperventilate. Furthermore, the psycho-physiological activation increased from a private to a public performance, and was higher during the performances than before or after them. The physiological activation was mainly independent of the MPA score. Finally, there was a low response coherence between the actual physiological activation and the self-reports on the instantaneous anxiety, tension, and perceived physiological activation.Given the high proportion of music students who consider stage fright as a problem and given the need for more help to better cope with it, a better understanding of this phenomenon and its inclusion in the educational process is fundamental to prevent future occupational problems. On the physiological level, breathing exercises might be a good means to decrease - but also to increase - the arousal associated with a public performance in order to meet an optimal level of arousal needed for a good performance.

Allegory is not obsolete as Samuel Coleridge and Johann Wolfgang von Goethe have claimed. It is alive and well and has transformed from a restrictive concept to a concept that is flexible and can form to meet the needs of the author or reader. The most efficient way to evidence this is by making a case study of it with a suitable work that will allow us to perceive its plasticity. This essay uses J.R.R. Tolkien’s The Lord of the Rings as a multi-perspective case study of the concept of allegory; the size and complexity of the narrative make it a suitable choice. My aim is to illustrate the plasticity of allegory as a concept and illuminate some of the possibilities and pitfalls of allegory and allegoresis. As to whether The Lord of the Rings can be treated as an allegory, it will be examined from three different perspectives: as a purely writerly process, a middle ground of writer and reader and as a purely readerly process. The Lord of the Rings will then be compared to a series of concepts of allegorical theory such as Plato’s classical “The Ring of Gyges”, William Langland’s classic The Vision of William Concerning Piers the Plowman and contemporary allegories of racism and homoeroticism to demonstrate just how adaptable this concept is. The position of this essay is that the concept of allegory has changed over time since its conception and become more malleable. This poses certain dangers as allegory has become an all-round tool for anyone to do anything that has few limitations and has lost its early rigid form and now favours an almost anything goes approach.

Using a multi-perspective vignette design, we explored predictors of young peoples' (N = 119) propensity to engage in unfaithful activities while dating. Demographic measures, a datding investment model, and measures of functional and dysfunctional impulsivity were used to predict inclination to engage in each of two extradyadic activities (kissing and sexual activity). The results of moderated multiple regression analyses revealed that a respondent's number of sexual partners, level of dysfunctional impulsivity, satisfaction with current relationship, and quality of relationship alternatives significantly predicted inclination to engage in both of the extradyadic activities. Consistent with previous findings, gender only showed significant predictive value in relation to extradyadic sex inclination. Moreover, the association between sex, love, and marriage interacted with gender in the prediction of both extradyadic activities and interacted with commitment in the prediction of extradyadic sex inclination. Suggestions for future research in this area are offered in light of these new findings.

OBJECTIVE: To explore patients' and physicians' experiences of atrial fibrillation consultations and oral anticoagulation decision-making. DESIGN: Multi-perspective interpretative phenomenological analyses. METHODS: Participants included small homogeneous subgroups: AF patients who accepted (n=4), refused (n=4), or discontinued (n=3) warfarin, and four physician subgroups (n=4 each group): consultant cardiologists, consultant general physicians, general practitioners and cardiology registrars. Semi-structured interviews were conducted. Transcripts were analysed using multi-perspective IPA analyses to attend to individuals within subgroups and making comparisons within and between groups. RESULTS: Three themes represented patients' experiences: Positioning within the physician-patient dyad, Health-life balance, and Drug myths and fear of stroke. Physicians' accounts generated three themes: Mechanised metaphors and probabilities, Navigating toward the 'right' decision, and Negotiating systemic factors. CONCLUSIONS: This multi-perspective IPA design facilitated an understanding of the diagnostic consultation and treatment decision-making which foregrounded patients' and physicians' experiences. We drew on Habermas' theory of communicative action to recommend broadening the content within consultations and shifting the focus to patients' life contexts. Interventions including specialist multidisciplinary teams, flexible management in primary care, and multifaceted interventions for information provision may enable the creation of an environment that supports genuine patient involvement and participatory decision-making.

Tämä teorialähtöinen, hermeneuttinen tutkimus sijoittuu käännöstieteen sekä uskonnon- ja kielifilosofian rajapintaan. Tutkimuksessa kuvataan kristinuskon tekstimaailmaa relevantin tulkintakehyksen kautta sekä esitetään tekstimaailman tulkintaan soveltuva lähestymistapa ammattikääntäjän eli välittävän vastaanottajan näkökulmasta. Tutkimus pureutuu käännösprosessin hermeneutiikkaan eli lähdetekstin ja sen maailman tulkintaan, ymmärtämiseen ja selittämiseen liittyviin aspekteihin. Tutkimuksessa ei esitetä käännösratkaisuja. Tutkimus nostaa esiin filosofisen ja teologisen hermeneutiikan peruskysymyksiä. Niitä ovat Raamatun tekstien vaikutushistoria, erilaiset todellisuus- ja kielikäsitykset, kirkon oppi, teologian pääsuuntaukset, uskonnolliset yhteisöt ja niiden perinteet, inhimillinen kulttuuri ja aika. Ne ovat ulottuvuuksia, jotka vaikuttavat kääntäjän tekstin- ja maailmantulkintaan ja vaativat laajojen kontekstien huomioonottamista sekä lähestymistä monista eri näkökulmista. Ludwig Wittgensteinin myöhäisfilosofiaan liittyvän kielipelin idea tarjoaa ajatusmallin, jonka avulla uskonnon käsite-, merkki- ja tekstimaailmalle voidaan luoda moninäkökulmainen tulkintakehys. Kielipelin käsitettä käytetään tässä tutkimuksessa tekstien samankaltaisuutta ja erilaisuutta kokoavana järjestelmänä, joka toimii intratekstuaalisesti eli sillä on omat pelisääntönsä, tulkinnan lähteensä sekä tunnistettava identiteetti. Järjestelmän keskiössä ovat uskonnon konstituioivat käsitteet ja kertomukset, jotka ovat muiden tulkintojen eli metatekstien lähde. Kääntäjän varsinaisina tulkintakohteina ovat metatekstit, eivät raamatunkääntämiseen liittyvät kysymykset suoranaisesti. Tutkimuksessa luodaan kuitenkin tulkintamalli, jonka mukaan metatekstejä ja raamatun tekstejä luetaan rinnakkain. Ymmärtäminen ja ongelmanratkaisu rakentuvat tekstuaalisen kommunikaation pohjalta. Tekstejä luetaan sekä sääntöteorian että narratiivisen teorian valossa. Kertomus puhuttelee vastaanottajaa eri tavalla kuin sääntö. Tulkintamallissa yhdistyvät sekä analyyttinen että luovan mielikuvituksen sallima lukutapa. Molemmat toimivat yhdessä kääntäjän tekstin- merkin- ja maailmantulkinnan apuna. Tutkimuksessa pohditaan myös tekstiteorettisia kysymyksiä, tekstin ja merkin käsitteitä sekä niiden toimintadynamiikkaa. Tulkinnan mekanismi esitetään semioosin käsitteen avulla. Teksti määritellään heuristiseksi ja eksemplaariseksi kuvaukseksi maailmasta, ja se edustaa vain osaa tulkintakokonaisuudesta. Kääntäjän hermeneuttinen kenttä ulotetaan tekstinulkoiseen maailmaan, käytäntöön ja elämänmuotoon.

Die stereoskopische 3-D-Darstellung beruht auf der naturgetreuen Präsentation verschiedener Perspektiven für das rechte und linke Auge. Sie erlangt in der Medizin, der Architektur, im Design sowie bei Computerspielen und im Kino, zukünftig möglicherweise auch im Fernsehen, eine immer größere Bedeutung. 3-D-Displays dienen der zusätzlichen Wiedergabe der räumlichen Tiefe und lassen sich grob in die vier Gruppen Stereoskope und Head-mounted-Displays, Brillensysteme, autostereoskopische Displays sowie echte 3-D-Displays einteilen. Darunter besitzt der autostereoskopische Ansatz ohne Brillen, bei dem N≥2 Perspektiven genutzt werden, ein hohes Potenzial. Die beste Qualität in dieser Gruppe kann mit der Methode der Integral Photography, die sowohl horizontale als auch vertikale Parallaxe kodiert, erreicht werden. Allerdings ist das Verfahren sehr aufwendig und wird deshalb wenig genutzt. Den besten Kompromiss zwischen Leistung und Preis bieten präzise gefertigte Linsenrasterscheiben (LRS), die hinsichtlich Lichtausbeute und optischen Eigenschaften den bereits früher bekannten Barrieremasken überlegen sind. Insbesondere für die ergonomisch günstige Multiperspektiven-3-D-Darstellung wird eine hohe physikalische Monitorauflösung benötigt. Diese ist bei modernen TFT-Displays schon recht hoch. Eine weitere Verbesserung mit dem theoretischen Faktor drei erreicht man durch gezielte Ansteuerung der einzelnen, nebeneinander angeordneten Subpixel in den Farben Rot, Grün und Blau. Ermöglicht wird dies durch die um etwa eine Größenordnung geringere Farbauflösung des menschlichen visuellen Systems im Vergleich zur Helligkeitsauflösung. Somit gelingt die Implementierung einer Subpixel-Filterung, welche entsprechend den physiologischen Gegebenheiten mit dem in Luminanz und Chrominanz trennenden YUV-Farbmodell arbeitet. Weiterhin erweist sich eine Schrägstellung der Linsen im Verhältnis von 1:6 als günstig. Farbstörungen werden minimiert, und die Schärfe der Bilder wird durch eine weniger systematische Vergrößerung der technologisch unvermeidbaren Trennelemente zwischen den Subpixeln erhöht. Der Grad der Schrägstellung ist frei wählbar. In diesem Sinne ist die Filterung als adaptiv an den Neigungswinkel zu verstehen, obwohl dieser Wert für einen konkreten 3-D-Monitor eine Invariante darstellt. Die zu maximierende Zielgröße ist der Parameter Perspektiven-Pixel als Produkt aus Anzahl der Perspektiven N und der effektiven Auflösung pro Perspektive. Der Idealfall einer Verdreifachung wird praktisch nicht erreicht. Messungen mit Hilfe von Testbildern sowie Schrifterkennungstests lieferten einen Wert von knapp über 2. Dies ist trotzdem als eine signifikante Verbesserung der Qualität der 3-D-Darstellung anzusehen. In der Zukunft sind weitere Verbesserungen hinsichtlich der Zielgröße durch Nutzung neuer, feiner als TFT auflösender Technologien wie LCoS oder OLED zu erwarten. Eine Kombination mit der vorgeschlagenen Filtermethode wird natürlich weiterhin möglich und ggf. auch sinnvoll sein.

Among a variety of learning conceptions, David Kolb´s Experiential Learning Theory proposes four different learning styles: diverging, characterized by orientation towards people and multi-perspective vision; assimilating, concerned with ideas and abstract concepts as well as theory formulation; converging, expert in dealing with technical tasks and problem solving; and accommodating, risk taker and good at getting things done. Interesting correlations have been pointed out between Kolb s learning styles, professional careers and genders. With respect to behaviors, specific cognitive skills and interests, sex differences are widely known, and explained by Evolutionary Psychology as the result of distinct selective pressures acting on each gender. The aim of this research was to assess adolescents learning styles and their relation with interests on school and career choices, analyzing possible gender differences. We distributed questionnaires to 221 senior high school students to research their preferences for school disciplines, professional activities and career choices. The Learning Style Inventory specified the learning style of each individual. Our results showed a high frequency of reflective styles, with predominance of females as diverging and males as assimilating. Concerning school and professional interests, there were correlations between styles oriented towards the abstract and technical interests. Moreover, females preferred disciplines related to languages and interpersonal activities while males preferred disciplines related to science and technical activities. There were more males in exact science and engineering careers, and more females in social science and applied social science. Correlations found between learning styles, school and professional interests corroborate Kolb´s propositions, and the findings about gender differences are supported by Evolutionary Psychology theories

This article offers an account of the 50th Ghanaian independence-day celebrations during March 2007. The multi-perspective approach examines how celebrations were experienced in the Ghanaian capital Accra by the political elite and the grass roots at a variety of official and unofficial events that took place on 5 and 6 March 2007. During the festivities the authors accompanied Ghanaian friends from different political factions and thus provide close-hand accounts of political controversies over issues regarding how the nation ought to organise and celebrate its Independence Day, controversies which provide important insights into Ghanaian political culture. From this it is clear that the celebrations not only serve as expressions of national pride but also moments of critical reflection on the nation, national values and socio-political unity. These reflections, manifest as disputes about national and ethnic symbols, centre on the conditions and limits of political, social, ethnic and regional inclusiveness. At the same time, underlying such disputes are commonalities resting not on substantive symbols, cultural traits or other objectifiable characteristics, but on a Ghanaian consensus to agree on the issues at stake and on the rules of debate. Controversy thus functions not to divide but rather to strengthen national consciousness and deepen a sense of commonality that Ghanaians generally express as their commitment to ‘unity in diversity’.

This thesis is devoted to the study of the properties of high-redsfhit galaxies in the epoch 1 < z < 3, when a substantial fraction of galaxy mass was assembled, and when the evolution of the star-formation rate density peaked. Following a multi-perspective approach and using the most recent and high-quality data available (spectra, photometry and imaging), the morphologies and the star-formation properties of high-redsfhit galaxies were investigated. Through an accurate morphological analyses, the built up of the Hubble sequence was placed around z ~ 2.5. High-redshift galaxies appear, in general, much more irregular and asymmetric than local ones. Moreover, the occurrence of morphological k-­correction is less pronounced than in the local Universe. Different star-formation rate indicators were also studied. The comparison of ultra-violet and optical based estimates, with the values derived from infra-red luminosity showed that the traditional way of addressing the dust obscuration is problematic, at high-redshifts, and new models of dust geometry and composition are required. Finally, by means of stacking techniques applied to rest-frame ultra-violet spectra of star-forming galaxies at z~2, the warm phase of galactic-scale outflows was studied. Evidence was found of escaping gas at velocities of ~ 100 km/s. Studying the correlation of inter-­stellar absorption lines equivalent widths with galaxy physical properties, the intensity of the outflow-related spectral features was proven to depend strongly on a combination of the velocity dispersion of the gas and its geometry.

The development of the Web 2.0 led to the birth of new textual genres such as blogs, reviews or forum entries. The increasing number of such texts and the highly diverse topics they discuss make blogs a rich source for analysis. This paper presents a comparative study on open domain and opinion QA systems. A collection of opinion and mixed fact-opinion questions in English is defined and two Question Answering systems are employed to retrieve the answers to these queries. The first one is generic, while the second is specific for emotions. We comparatively evaluate and analyze the systems’ results, concluding that opinion Question Answering requires the use of specific resources and methods.

The overarching purpose of this research program was to describe how intervening for academic deficits may be accompanied by changes in mental health. This multi-dimensional, multi-perspective, and iterative research program was developed to report on two distinct but related studies that addressed the same issue: in what ways does the mental health of students change as they transition from being struggling readers to more able readers? To describe the changes, these studies used a number of qualitative research methodologies—focus groups, individual interviews, and ethnographic case studies. Themes that emerged from the focus group and interview data in the first study were used to create a model that guided observations and interview questions in the second study. The first study described what parents, classroom teachers, and two reading instructors of nine previously struggling readers reported as the outcomes of becoming a more proficient reader. Data from this study indicated three broad domains in which change, as perceived by participants, occurred―cognitive/learning, behavioural/social, and psychological/emotional. Within these three domains, six dimensions were identified as having changed as reading improved: (a) academic achievement, (b) attitude, (c) attention, (d) behaviour, (e) mental health, and (f) empowerment. These domains, dimensions, and 15 constituent elements were used to create the model to guide the subsequent study. The purpose of the second study was to validate and refine this model by using an ethnographic case study approach to explore the ways in which the model accounted for the changes in reading and mental health seen in three boys over the months they participated in the intervention. By investigating the relationship between learning to read and mental health, this research aimed to enhance our understanding of how gains in reading may also improve the mental health of struggling readers. The model was found to be robust and a convenient conceptual framework to further our understanding of this relationship. Importantly, gains made in the cognitive/learning domain through an effective reading intervention, offered in a supportive learning environment, were shown to be accompanied by concomitant gains in both the behavioural/social and psychological/emotional domains—all of which enhance student thriving.

This thesis reports a cross-national study carried out in England and India in an attempt to clarify the association of certain cultural and non-cultural characteristics with people's work-related attitudes and values, and with the structure of their work organizations. Three perspectives are considered to be relevant to the objectives of the study. The contingency perspective suggests that a 'fit' between an organization's context and its structural arrangements will be fundamentally necessary for achieving success and survival. The political economy perspective argues for the determining role of the social and economic structures within which the organization operates. The culturalist perspective looks to cultural attitudes and values of organizational members for an explanation for their organization's structure. The empirical investigation was carried out in three stages in each of the two countries involved by means of surveys of cultural attitudes, work-related attitudes and organizational structures and systems. The cultural surveys suggested that Indian and English people were different from one another with regard to fear of, and respect and obedience to, their seniors, ability to cope with ambiguity, honesty, independence, expression of emotions, fatalism, reserve, and care for others; they were similar with regard to tolerance, friendliness, attitude to change, attitude to law, self-control and self-confidence, and attitude to social differentiation. The second stage of the study, involving the employees of fourteen organizations, found that the English ones perceived themselves to have more power at work, expressed more tolerance for ambiguity, and had different expectations from their job than did the Indian equivalents. The two samples were similar with respect to commitment to their company and trust in their colleagues. The findings also suggested that employees' occupations, education and age had some influences on their work-related attitudes. The final stage of the research was a study of structures, control systems, and reward and punishment policies of the same fourteen organizations which were matched almost completely on their contextual factors across the two countries. English and Indian organizations were found to be similar in terms of centralization, specialization, chief executive's span of control, height and management control strategies. English organizations, however, were far more formalized, spent more time on consultation and their managers delegated authority lower down the hierarchy than Indian organizations. The major finding of the study was the multiple association that cultural, national and contingency factors had with the structural characteristics of the organizations and with the work-related attitudes of their members. On the basis of this finding, a multi-perspective model for understanding organizational structures and systems is proposed in which the contributions made by contingency, political economy and cultural perspectives are recognized and incorporated.

Sustainable development is notoriously difficult to grasp for students and professionals. Multidimensional, encompassing social, ecological and economic theories, policies and practice, it can be a maze of complexity and contradiction. This powerful new textbook, by a topic instructor in the field, is the first to unravel sustainable development and provide readers with the deep understanding so often missing in other texts. The book adopts a multi-perspective approach designed specifically to allow access to the topic from a wide range of educational and professional backgrounds and to develop understanding of a diversity of approaches and traditions at different levels. It features multiple entry points, explains jargon and explores controversies. Also offering boxed examples from the local to the global, Understanding Sustainable Development is the most complete guide to the subject for course leaders, students and self-learners.
