Den utvärdera(n)de staten : Utvärderingens institutionalisering på den högre utbildningens område

In recent years evaluation has become a very important element in the public administration. The Swedish state administration to a significant extent both evaluates and is evaluated. This means that the evaluating state is at the same time the evaluated state. In this dissertation the institutionalization of evaluation is studied in a field within which this development has been particularly lively and interesting, namely the field of higher education. The dissertation focuses on evaluation activity that has been carried out in conjunction with central public authorities within higher education: the Office of the Chancellor of the Universities and Colleges in Sweden, the National Swedish Board of Universities and Colleges, and the Office of the University Chancellor, and encompasses the period 1964-1995. A newly revived research tradition within political science – historical institutionalism – is used as a perspective and a methodology. Since the application of this tradition has not yet been fully tested, another purpose is to examine the practical utility of this analytical tool and the kind of knowledge that it produces. The dissertation thereby combines the fields of education policy, evaluation research and institutional theory. The beginning of the institution has been dated to the end of the 1960s and beginning of the 1970s. In the dissertation the forces behind the initiation of the institution are taken up. Events and developments in the field that have influenced the further development of the institution have been identified and analyzed. Developments reveal that the institution has been stable during the entire period of time under study, despite some changes. The use of historical institutionalism as a perspective and methodology has proven satisfactory on a general level. However, special solutions have been required as problems and ambiguities have arisen. The dissertation concludes with reflections on the practical utility of historical institutionalism in political science research.

Argumentation and artifacts for intelligent multi-agent systems

Reasoning under uncertainty is a human capacity that in software system is necessary and often hidden. Argumentation theory and logic make explicit non-monotonic information in order to enable automatic forms of reasoning under uncertainty. In human organization Distributed Cognition and Activity Theory explain how artifacts are fundamental in all cognitive process. Then, in this thesis we search to understand the use of cognitive artifacts in an new argumentation framework for an agent-based artificial society.

I sensi spirituali nel Liber di Angela da Foligno. La metafora del "gusto" nel Liber di Angela da Foligno e nella mistica femminile francescana tra XIII e XIV secolo.

Angela da Foligno’s Liber is a fundamental text for the scholar of Women Mystics between the XIIIth and the XIVth century in Italy and all over Europe, and it has been chosen in my research because of its originality, with refer of its feminine and franciscan essence. Angela teaches to the italian hagiographic tradition the internal point of view of the holy woman, who becomes the teller of her both ordinary and extraordinary experiences. After giving references about the religious and social historical universe in evolution during the XIIth century, my research proceeds with a linguistic and rhetorical analysis based upon the Liber. I have been searching in Angela’s text and in contemporary italian feminine hagiography the sensory metaphor of “tasting”. That kind of metaphor has an ancient memory and, thanks to the Origene’s studies - the Christian Father of the IIIrd century - we can easily recognize it already in the Bible; Origene identifies the sensory metaphor as a rhetoric system, able to exemplify the God learning process of soul. Theory of “spiritual senses”, theory of vision and rhetoric, evolving from the IIIrd to the XIIIth century, are the theological and linguistic heritage of our feminine and franciscan literature. Inside of that, the metaphor of “tasting” moves and changes, therefore becoming the favourite way of mystics to represent the contact of their souls with God.

Testo e memoria tra semiotica e scienze cognitive: una situazione sperimentale intorno al ricordo di un film

The research project presented in this dissertation is about text and memory. The title of the work is "Text and memory between Semiotics and Cognitive Science: an experimental setting about remembering a movie". The object of the research is the relationship between texts or "textuality" - using a more general semiotic term - and memory. The goal is to analyze the link between those semiotic artifacts that a culture defines as autonomous meaningful objects - namely texts - and the cognitive performance of memory that allows to remember them. An active dialogue between Semiotics and Cognitive Science is the theoretical paradigm in which this research is set, the major intend is to establish a productive alignment between the "theory of text" developed in Semiotics and the "theory of memory" outlined in Cognitive Science. In particular the research is an attempt to study how human subjects remember and/or misremember a film, as a specific case study; in semiotics, films are “cinematographic texts”. The research is based on the production of a corpus of data gained through the qualitative method of interviewing. After an initial screening of a fulllength feature film each participant of the experiment has been interviewed twice, according to a pre-established set of questions. The first interview immediately after the screening: the subsequent, follow-up interview three months from screening. The purpose of this design is to elicit two types of recall from the participants. In order to conduce a comparative inquiry, three films have been used in the experimental setting. Each film has been watched by thirteen subjects, that have been interviewed twice. The corpus of data is then made by seventy-eight interviews. The present dissertation displays the results of the investigation of these interviews. It is divided into six main parts. Chapter one presents a theoretical framework about the two main issues: memory and text. The issue of the memory is introduced through many recherches drown up in the field of Cognitive Science and Neuroscience. It is developed, at the same time, a possible relationship with a semiotic approach. The theoretical debate about textuality, characterizing the field of Semiotics, is examined in the same chapter. Chapter two deals with methodology, showing the process of definition of the whole method used for production of the corpus of data. The interview is explored in detail: how it is born, what are the expected results, what are the main underlying hypothesis. In Chapter three the investigation of the answers given by the spectators starts. It is examined the phenomenon of the outstanding details of the process of remembering, trying to define them in a semiotic way. Moreover there is an investigation of the most remembered scenes in the movie. Chapter four considers how the spectators deal with the whole narrative. At the same time it is examined what they think about the global meaning of the film. Chapter five is about affects. It tries to define the role of emotions in the process of comprehension and remembering. Chapter six presents a study of how the spectators account for a single scene of the movie. The complete work offers a broad perspective about the semiotic issue of textuality, using both a semiotic competence and a cognitive one. At the same time it presents a new outlook on the issue of memory, opening several direction of research.

La traduzione letteraria in Unione Sovietica (1930-1955)

In Unione Sovietica il partito mette in atto un sistema di istituzioni per controllare il mondo culturale e la produzione scritta: il Glavlit, il massimo istituto censorio, l’Unione degli scrittori, un’editoria centralizzata e statalizzata e un unico metodo creativo possibile, il realismo socialista. Il settore della traduzione letteraria e della ricezione della letteratura straniera vengono ugualmente posti sotto controllo. All’interno dell’Unione degli scrittori operano la Sezione dei Traduttori, a cui spetta la formazione dei nuovi traduttori sovietici, e la Commissione Straniera, che stabilisce quali autori e quali libri occidentali debbano essere tradotti. Il Reparto straniero del Glavlit controlla il materiale a stampa proveniente dall’estero, la sua distribuzione e le modalità di consultazione e si occupa di effettuare una censura sia sul testo in lingua straniera che su quello tradotto in lingua russa. Parallelamente, il codice estetico e normativo del realismo socialista comincia a influenzare lo sviluppo della teoria della traduzione. La traduttologia si allinea alla critica letteraria ufficiale e promuove un approccio libero al testo che permetta l’introduzione di modifiche testuali arbitrarie da parte del traduttore o del redattore.

Frammenti di Erodoto: Problemi e metodi nello studio della storiografia frammentaria

Il percorso sui Frammenti di Erodoto è cronologico. L'introduzione presenta criteri di lavoro, un esempio di studio sul Proemio delle Storie e la struttura generale. Per ogni momento è preso in considerazione un fenomeno particolare con un esempio. Il primo caso è contemporaneo ad Erodoto. Si tratta di un test che riguarda la criticità di alcuni concetti chiave tradizionali: intertestualità e riferimenti letterali. Il secondo capitolo è uno studio sulla storiografica di IV secolo a.C., periodo di fioritura e determinazione delle norme del genere. Qui si mettono in luce la criticità dei frammenti multipli aprendo in questo modo ampie possibilità di ricerca. Il capitolo successivo, sulla tradizione papiracea mostra il passaggio storico tra la tradizione indiretta a la tradizione manoscritta e permette uno sguardo all'epoca alessandrina. Include un catalogo ed alcuni aggiornamenti. Il capitolo quinto pone invece problemi tradizionali di trasmissione delle tradizioni storiche affrontando lo studio di FGrHist 104, testo che permette di osservare passaggi della storiografia di quinto e quarto secolo avanti Cristo. I due capitoli sulle immagini e sul Rinascimento, paralleli per quanto riguarda i riferimenti cronologici, offrono un ponte per passare dal discorso storiografico a quello in cui la consapevolezza di Erodoto è già maturata come parte della ”cultura”. Alto Medioevo, Umanesimo e Rinascimento offrono spazio a storie delle Storie che iniziano ad essere quasi di ricezione di Erodoto. Questo tema è l'oggetto dei due capitoli finali, studi legati alla presenza o assenza di Erodoto in discipline e pensieri moderni e contemporanei: il pensiero di genere e l’analisi conversazionale. Le appendici completano soprattutto il capitolo su Aristodemo con uno studio sul codice che lo trasmette, il papiro P.Oxy 2469 e il testo stesso, con traduzione e commento storico. Il lavoro si completa con una premessa, una bibliografia strutturata e indici di persone e passi citati.

Describing and explaining the foreign expansion of network managing electronic business companies (NM-EBCs)

This study deals with the internationalization behavior of a new and specific type of e-business company, namely the network managing e-business company (NM-EBC). The business model of such e-business companies is based on providing a platform and applications for users to connect and interact, on gathering and channeling the inputs provided by the users, and on organizing and managing the cross-relationships of the various participants. Examples are online communities, matching platforms, and portals. Since NM-EBCs internationalize by replicating their business model in a foreign market and by building up and managing a network of users, who provide input themselves and interact with each other, they have to convince users in foreign markets to join the network and hence to adopt their platform. We draw upon Rogers’ Diffusion of Innovations Theory and Network Theory to explain the internationalization behavior of NM-EBCs. These two theories originate from neighboring disciplines and have not yet been used to explain the internationalization of firms. We combine both theories and formulate hypotheses about which strategies NM-EBCs may choose to expand abroad. To test the applicability of our theory and to gain rich data about the internationalization behavior of these firms, we carried out multiple case studies with internationally active Germany-based NM-EBCs.

Canonical group quantization and boundary conditions

In the present thesis, we study quantization of classical systems with non-trivial phase spaces using the group-theoretical quantization technique proposed by Isham. Our main goal is a better understanding of global and topological aspects of quantum theory. In practice, the group-theoretical approach enables direct quantization of systems subject to constraints and boundary conditions in a natural and physically transparent manner -- cases for which the canonical quantization method of Dirac fails. First, we provide a clarification of the quantization formalism. In contrast to prior treatments, we introduce a sharp distinction between the two group structures that are involved and explain their physical meaning. The benefit is a consistent and conceptually much clearer construction of the Canonical Group. In particular, we shed light upon the 'pathological' case for which the Canonical Group must be defined via a central Lie algebra extension and emphasise the role of the central extension in general. In addition, we study direct quantization of a particle restricted to a half-line with 'hard wall' boundary condition. Despite the apparent simplicity of this example, we show that a naive quantization attempt based on the cotangent bundle over the half-line as classical phase space leads to an incomplete quantum theory; the reflection which is a characteristic aspect of the 'hard wall' is not reproduced. Instead, we propose a different phase space that realises the necessary boundary condition as a topological feature and demonstrate that quantization yields a suitable quantum theory for the half-line model. The insights gained in the present special case improve our understanding of the relation between classical and quantum theory and illustrate how contact interactions may be incorporated.

Accretion of Mass and Angular Momentum onto The Discs of Spiral Galaxies

In this Thesis, we study the accretion of mass and angular momentum onto the disc of spiral galaxies from a global and a local perspective and comparing theory predictions with several observational data. First, we propose a method to measure the specific mass and radial growth rates of stellar discs, based on their star formation rate density profiles and we apply it to a sample of nearby spiral galaxies. We find a positive radial growth rate for almost all galaxies in our sample. Our galaxies grow in size, on average, at one third of the rate at which they grow in mass. Our results are in agreement with theoretical expectations if known scaling relations of disc galaxies are not evolving with time. We also propose a novel method to reconstruct accretion profiles and the local angular momentum of the accreting material from the observed structural and chemical properties of spiral galaxies. Applied to the Milky Way and to one external galaxy, our analysis indicates that accretion occurs at relatively large radii and has a local deficit of angular momentum with respect to the disc. Finally, we show how structure and kinematics of hot gaseous coronae, which are believed to be the source of mass and angular momentum of massive spiral galaxies, can be reconstructed from their angular momentum and entropy distributions. We find that isothermal models with cosmologically motivated angular momentum distributions are compatible with several independent observational constraints. We also consider more complex baroclinic equilibria: we describe a new parametrization for these states, a new self-similar family of solution and a method for reconstructing structure and kinematics from the joint angular momentum/entropy distribution.

Schriftlicher Text im Film und seine Übersetzung : die Inserts der BBC-Serie Sherlock (2010-12) ; aus der Perspektive von Untertiteltheorie, Comictheorie und Translationspraxis

Die BBC-Serie SHERLOCK war 2011 eine der meistexportierten Fernsehproduktionen Großbritanniens und wurde weltweit in viele Sprachen übersetzt. Eine der Herausforderungen bei der Übersetzung stellen die Schrifteinblendungen der Serie (kurz: Inserts) dar. Die Inserts versprachlichen die Gedanken des Protagonisten, bilden schriftliche und digitale Kommunikation ab und zeichnen sich dabei durch ihre visuelle Auffälligkeit und teilweise als einzige Träger sprachlicher Kommunikation aus, womit sie zum wichtigen ästhetischen und narrativen Mittel in der Serie werden. Interessanterweise sind in der Übersetztung alle stilistischen Eigenschaften der Original-Inserts erhalten. In dieser Arbeit wird einerseits untersucht, wie Schrifteinblendungen im Film theoretisch beschrieben werden können, und andererseits, was sie in der Praxis so übersetzt werden können, wie es in der deutschen Version von Sherlock geschah. Zur theoretischen Beschreibung werden zunächst die Schrifteinblendungen in Sherlock Untertitelungsnormen anhand relevanter grundlegender semiotischer Dimensionen gegenübergestellt. Weiterhin wird das Verhältnis zwischen Schrifteinblendungen und Filmbild erkundet. Dazu wird geprüft, wie gut verschiedene Beschreibungsansätze zu Text-Bild-Verhältnissen aus der Sprachwissenschaft, Comicforschung, Übersetzungswissenschaft und Typografie die Einblendungen in Sherlock erklären können. Im praktischen Teil wird die Übersetzung der Einblendungen beleuchtet. Der Übersetzungsprozess bei der deutschen Version wird auf Grundlage eines Experteninterviews mit dem Synchronautor der Serie rekonstruiert, der auch für die Formulierung der Inserts zuständig war. Abschließend werden spezifische Übersetzungsprobleme der Inserts aus der zweiten Staffel von SHERLOCK diskutiert. Es zeigt sich, dass Untertitelungsnormen zur Beschreibung von Inserts nicht geeignet sind, da sie in Dimensionen wie Position, grafische Gestaltung, Animation, Soundeffekte, aber auch Timing stark eingeschränkt sind. Dies lässt sich durch das historisch geprägte Verständnis von Untertiteln erklären, die als möglichst wenig störendes Beiwerk zum fertigen Filmbild und -ablauf (notgedrungen) hinzugefügt werden, wohingegen für die Inserts in SHERLOCK teilweise sogar ein zentraler Platz in der Bild- und Szenenkomposition bereits bei den Dreharbeiten vorgesehen wurde. In Bezug auf Text-Bild-Verhältnisse zeigen sich die größten Parallelen zu Ansätzen aus der Comicforschung, da auch dort schriftliche Texte im Bild eingebettet sind anstatt andersherum. Allerdings sind auch diese Ansätze zur Beschreibung von Bewegung und Ton unzureichend. Die Erkundung der Erklärungsreichweite weiterer vielversprechender Konzepte, wie Interface und Usability, bleibt ein Ziel für künftige Studien. Aus dem Experteninterview lässt sich schließen, dass die Übersetzung von Inserts ein neues, noch unstandardisiertes Verfahren ist, in dem idiosynkratische praktische Lösungen zur sprachübergreifenden Kommunikation zwischen verschiedenen Prozessbeteiligten zum Einsatz kommen. Bei hochqualitative Produktionen zeigt ist auch für die ersetzende Insertübersetzung der Einsatz von Grafikern unerlässlich, zumindest für die Erstellung neuer Inserts als Übersetzungen von gefilmtem Text (Display). Hierbei sind die theoretisch möglichen Synergien zwischen Sprach- und Bildexperten noch nicht voll ausgeschöpft. Zudem zeigt sich Optimierungspotential mit Blick auf die Bereitstellung von sorgfältiger Dokumentation zur ausgangssprachlichen Version. Diese wäre als Referenzmaterial für die Übersetzung insbesondere auch für Zwecke der internationalen Qualitätssicherung relevant. Die übersetzten Inserts in der deutschen Version weisen insgesamt eine sehr hohe Qualität auf. Übersetzungsprobleme ergeben sich für das genretypische Element der Codes, die wegen ihrer Kompaktheit und multiplen Bezügen zum Film eine Herausforderung darstellen. Neben weiteren bekannten Übersetzungsproblemen wie intertextuellen Bezügen und Realia stellt sich immer wieder die Frage, wieviel der im Original dargestellten Insert- und Displaytexte übersetzt werden müssen. Aus Gründen der visuellen Konsistenz wurden neue Inserts zur Übersetzung von Displays notwendig. Außerdem stellt sich die Frage insbesondere bei Fülltexten. Sie dienen der Repräsentation von Text und der Erweiterung der Grenzen der fiktiv dargestellten Welt, sind allerdings mit hohem Übersetzungsaufwand bei minimaler Bedeutung für die Handlung verbunden.

Prediction accuracy of young and middle-aged adults in memory for familiar and unfamiliar texts

This study investigated the influence of age, familiarity, and level of exposure on the metamemorial skill of prediction accuracy on a future test. Young (17 to 23 years old) and middle-aged adults (35 to 50 years old) were asked to predict their memory for text material. Participants made predictions on a familiar text and an unfamiliar text, at three different levels of exposure to each. The middle-aged adults were superior to the younger adults at predicting performance. This finding indicates that metamemory may increase from youth to middle age. Other findings include superior prediction accuracy for unfamiliar compared to familiar material, a result conflicting with previous findings, and an interaction between level of exposure and familiarity that appears to modify the main effects of those variables.

"Framing Counterspaces: Forms and Meanings of Graffiti in Berlin's Linguistic Landscape"

Street art and graffiti are integral parts of Berlin’s urban space, which has undergone dramatic transformations in the past two decades. Graffiti texts constitute a critical comment on these urban transformations. This talk analyzes the connection between the phenomenon of street art and trajectories in urban planning in post-wall Berlin. My current research explores the meaning of various forms of street art (such as graffiti, posters, sticker art, stencils) as texts in Berlin’s linguistic landscape. Linguistic Landscape research pays critical attention to language, words, and images displayed and exposed in public spaces. The field of Linguistic Landscapes has only recently begun to include graffiti texts in analyses of text and space to fully comprehend the semiotics of the street. In the case of Germany’s capital, graffiti writing enters into a critical dialogue with the environment and provides a readable text to understand the city.

Anomalous Velocity Distributions in Active Brownian Suspensions

Large-scale simulations and analytical theory have been combined to obtain the nonequilibrium velocity distribution, f(v), of randomly accelerated particles in suspension. The simulations are based on an event-driven algorithm, generalized to include friction. They reveal strongly anomalous but largely universal distributions, which are independent of volume fraction and collision processes, which suggests a one-particle model should capture all the essential features. We have formulated this one-particle model and solved it analytically in the limit of strong damping, where we find that f (v) decays as 1/v for multiple decades, eventually crossing over to a Gaussian decay for the largest velocities. Many particle simulations and numerical solution of the one-particle model agree for all values of the damping.

Physical activity intensity and surrogate markers for cardiovascular health in adolescents

We examined the impact of physical activity (PA) on surrogate markers of cardiovascular health in adolescents. 52 healthy students (28 females, mean age 14.5 ± 0.7 years) were investigated. Microvascular endothelial function was assessed by peripheral arterial tonometry to determine reactive hyperemic index (RHI). Vagal activity was measured using 24 h analysis of heart rate variability [root mean square of successive normal-to-normal intervals (rMSSD)]. Exercise testing was performed to determine peak oxygen uptake ([Formula: see text]) and maximum power output. PA was assessed by accelerometry. Linear regression models were performed and adjusted for age, sex, skinfolds, and pubertal status. The cohort was dichotomized into two equally sized activity groups (low vs. high) based on the daily time spent in moderate-to-vigorous PA (MVPA, 3,000-5,200 counts(.)min(-1), model 1) and vigorous PA (VPA, >5,200 counts(.)min(-1), model 2). MVPA was an independent predictor for rMSSD (β = 0.448, P = 0.010), and VPA was associated with maximum power output (β = 0.248, P = 0.016). In model 1, the high MVPA group exhibited a higher vagal tone (rMSSD 49.2 ± 13.6 vs. 38.1 ± 11.7 ms, P = 0.006) and a lower systolic blood pressure (107.3 ± 9.9 vs. 112.9 ± 8.1 mmHg, P = 0.046). In model 2, the high VPA group had higher maximum power output values (3.9 ± 0.5 vs. 3.4 ± 0.5 W kg(-1), P = 0.012). In both models, no significant differences were observed for RHI and [Formula: see text]. In conclusion, in healthy adolescents, PA was associated with beneficial intensity-dependent effects on vagal tone, systolic blood pressure, and exercise capacity, but not on microvascular endothelial function.

Enhancing Sensitivity In Natural Product Nmr: Exploring Optimal Non-Uniform Sampling

Recent optimizations of NMR spectroscopy have focused their attention on innovations in new hardware, such as novel probes and higher field strengths. Only recently has the potential to enhance the sensitivity of NMR through data acquisition strategies been investigated. This thesis has focused on the practice of enhancing the signal-to-noise ratio (SNR) of NMR using non-uniform sampling (NUS). After first establishing the concept and exact theory of compounding sensitivity enhancements in multiple non-uniformly sampled indirect dimensions, a new result was derived that NUS enhances both SNR and resolution at any given signal evolution time. In contrast, uniform sampling alternately optimizes SNR (t < 1.26T2) or resolution (t~3T2), each at the expense of the other. Experiments were designed and conducted on a plant natural product to explore this behavior of NUS in which the SNR and resolution continue to improve as acquisition time increases. Possible absolute sensitivity improvements of 1.5 and 1.9 are possible in each indirect dimension for matched and 2x biased exponentially decaying sampling densities, respectively, at an acquisition time of ¿T2. Recommendations for breaking into the linear regime of maximum entropy (MaxEnt) are proposed. Furthermore, examination into a novel sinusoidal sampling density resulted in improved line shapes in MaxEnt reconstructions of NUS data and comparable enhancement to a matched exponential sampling density. The Absolute Sample Sensitivity derived and demonstrated here for NUS holds great promise in expanding the adoption of non-uniform sampling.
