Im Rahmen universitärer Projekte entwickelte E-Learning-Angebote werden nach ihrer Fertigstellung in der Regel nicht isoliert in der Lehre eingesetzt. Vielmehr sollen sie in bereits bestehende Curricula und traditionelle Präsenzveranstaltungen integriert werden. Der vorliegende Beitrag beschäftigt sich mit der Frage, wie eine solche Integration zu leisten ist und welche Aspekte dabei zu beachten, welche Aufgaben zu übernehmen sind. Am Beispiel des Projektes IMPULSEC wird gezeigt, wie und unter welchen Voraussetzungen am Entwicklungsstandort Osnabrück Lerninhalte und -ziele, Medien und Methoden sowie Sozial- und Organisationsformen von E-Learning-Angeboten mit denen der traditionellen Präsenzlehre zusammengeführt werden.(DIPF/Orig.)

Der Einsatz netzbasierter Diskussionsforen ist in vielen E-Learning-Szenarien zu finden: In ‚blended learning‘-Arrangements wird beispielsweise versucht, zwischen Präsenzsitzungen durch den Einsatz von Foren netzbasierte Diskussionsprozesse zu initiieren. Foren werden auch begleitend zur traditionellen Präsenzlehre eingesetzt, um z.B. der Besprechung von solchen Themen Raum und Zeit einzuräumen, welche in den wöchentlichen Präsenzsitzungen zu kurz kommen würden. Doch vor allem in rein virtuellen Lernszenarien spielen netzbasierte Foren eine besondere Rolle: Hier dienen sie als virtuelles Plenum der Kommunikation zwischen allen Teilnehmenden und bilden damit eine wichtige Funktion im Rahmen der Veranstaltung ab. Doch trotz dieser vielfältigen Einsatzmöglichkeiten lässt sich im Alltag der Hochschullehre immer wieder das Problem beobachten, dass Studierende die Option Foren zu nutzen nicht ausreichend aufgreifen. Oftmals werden Rolle und Aufgabe der Foren im Rahmen der gesamten Veranstaltung nicht transparent. Viele Hochschullehrende stellen sich die Frage, wie sie den Einsatz von Foren und damit die zusätzlichen Kommunikationsmöglichkeiten attraktiv gestalten können. Dieser Beitrag widmet sich diesem Problem, indem Einsatzszenarien netzbasierter Foren vorgestellt und aus den Erfahrungen mit mehreren virtuellen Konferenzen Gestaltungsoptionen und Moderationsstrategien für Foren abgeleitet werden.(DIPF/Orig.)

Der Einsatz von Fallstudien kann als wichtiges Bindeglied zur Verknüpfung von Theorie und Praxis betrachtet werden. Fallstudien ermöglichen die Anwendung theoretischen Grundlagenwissens und die Entwicklung überfachlicher Kompetenzen. Damit können sie einen wichtigen Beitrag zur beruflichen Handlungskompetenz genau dort leisten, wo praktische Erfahrungen im Rahmen der Aus-und Weiterbildung nicht möglich sind. Der Einsatz von Fallstudien sollte aus diesem Grund nicht nur den „klassischen“ Anwendungsdisziplinen wie den Rechtswissenschaften, der Betriebswirtschaftslehre oder der Psychologie vorbehalten sein. Auch im Bereich der Informatik können sie eine wichtige Ergänzung zu den bisher eingesetzten Methoden darstellen. Das im Kontext des Projekts New Economy1 entwickelte und hier vorgestellte Konzept zur didaktischen und technischen Aufbereitung von Fallstudien am Beispiel der IT-Aus- und Weiterbildung soll diese Diskussion anregen. Mit Hilfe des vorgestellten Ansatzes ist es möglich, unterschiedliche methodische Zugänge zu einer Fallstudie für eine computerbasierte Präsentation automatisch zu generieren und mit fachlichen Inhalten zu verknüpfen. Damit ist ein entscheidender Mehrwert gegenüber den bisherigen statischen und in sich geschlossenen Darstellungen gegeben. Der damit zu erreichende Qualitätssprung im Einsatz von Fallstudien in der universitären und betrieblichen Aus- und Weiterbildung stellt einen wichtigen Beitrag zur praxisorientierten Gestaltung von Blended Learning-Ansätzen dar.(DIPF/Orig.)

Diversity has become a buzz word in public discourse and in educational circles. Higher education institutions in the US have increasingly used this word as a cornerstone of their mission statements and have made increasing efforts to attract students from different backgrounds. As part of the increase in diversity efforts among US colleges, is a significant rise in the number of international students. Attracting international students has become a priority for U.S. universities regardless of size or location. This study examines the intersection between the structure of American educational environment and the blended identities of African Graduate Student Mothers. Within the context of contemporary diversity efforts in US educational institutions, this study examines both the structural environments and the socio-cultural constructs that affect the experiences of African graduate student mothers. Based on a qualitative research interview design, a total of nineteen African graduate student mothers at a Mid-Western University in the US were interviewed individually and in groups over a six weeks period. Results from this study show that apart from the difficult and often dehumanizing treatment African student mothers endure from immigration and consular officials in their various countries and ports of entry, they often find themselves at the margins of their various programs and departments with very little support if any. This is because most of them enroll into graduate programs after arriving as dependants of their spouses; a process that does not allow them to negotiate for departmental commitments and support prior to their arrival. Not only do these women face racial discrimination from white professors, staff and fellow students, but they also experience discrimination and hostilities from African Americans and other minority groups who see them as threats to the limited resources that are often set aside for minority groups in such institutions.

No Brasil o biodiesel é utilizado em misturas com óleo diesel em proporções de 5%, sem que haja modificações nos motores. Com o intuito de diversificar a utilização de oleaginosas não comestíveis no ramo dos biocombustíveis, e ainda vincular a produção com agricultura sustentável, uma alternativa para o RS é a utilização do óleo de tungue para a produção de biodiesel. A caracterização e quantificação de ácidos graxos do biodiesel de tungue, torna-se importante devido à seu exclusivo perfil graxo. Neste trabalho, foi estudado o desenvolvimento e validação de método para a determinação do perfil graxo do biodiesel metílico de tungue e blendas com soja utilizando GC-MS. Os parâmetros de validação considerados foram: curva analítica, linearidade, seletividade, limite de detecção e quantificação, robustez, precisão e exatidão. Para determinar as melhores condições cromatográficas, foram testadas diferentes programações de temperatura no forno cromatográfico; fluxo de gás; temperatura do injetor, detector e interface; e modo de injeção. As condições do GCMS após a otimização foram: injeção de 1 µL com injeção em alta pressão (300 kPa), T do injetor: 250 ºC, injeção split 1:30, fluxo de 1 mL min-1, coluna Rtx-5MS com dimensões 30 m x 0,25 mm x 0,25 µm, T forno: isoterma de 2 min a 130 ºC, aumento de 20 ºC/min até 220 ºC, aumento de 0,5ºC/min até 223ºC, aumento de 7 ºC/min até 250 ºC e isoterma em 250 ºC por 3 min, resultando em 20 min de análise. A temperatura da fonte e interface foram de 200 ºC e 250 ºC, respectivamente, com o MS no modo full scan, ionização por impacto eletrônico a 70 eV, e intervalo de massas de 30 a 500 u.m.a. A identificação do α-eleosteárico foi baseada na fragmentação característica do composto, pela comparação com o espectro do ácido linolênico, e ainda pelo tempo de retenção do composto. Na validação, as curvas analíticas apresentaram valores de r maiores que 0,99. O LD e LQ foram adequados, permitindo a quantificação de ésteres na concentração mínima de 0,6%. Os valores de exatidão ficaram entre 86 e 117%, com RSD% menores que 8%. O efeito matriz também foi avaliado, sendo que esse efeito foi considerado médio para a maioria dos compostos, ficando entre ± 20 e 50%. Durante a aplicação do método, o mesmo se mostrou adequado para amostras de biodiesel metílico de tungue e blendas com soja, nas proporções de 15:85, 20:80 e 25:75 (T:S, v/v). A aplicabilidade do método também foi testada para o biodiesel de soja, obtendo resultados satisfatórios, mostrando-se assim, além de tudo, ser um método robusto.

The view that Gothic literature emerged as a reaction against the prominence of the Greek classics, and that, as a result, it bears no trace of their influence, is a commonplace in Gothic studies. This thesis re-examines this view, arguing that the Gothic and the Classical were not in opposition to one another, and that Greek tragic poetry and myth should be counted among the literary sources that inspired early Gothic writers. The discussion is organised in three parts. Part I focuses on evidence which suggests that the Gothic and the Hellenic were closely associated in the minds of several British literati both on a political and aesthetic level. As is shown, the coincidence of the Hellenic with the Gothic revival in the second half of the eighteenth century inspired them not only to trace common ground between the Greek and Gothic traditions, but also to look at Greek tragic poetry and myth through Gothic eyes, bringing to light an unruly, ‘Dionysian’ world that suited their taste. The particulars of this coincidence, which has not thus far been discussed in Gothic studies, as well as evidence which suggests that several early Gothic writers were influenced by Greek tragedy and myth, open up new avenues for research on the thematic and aesthetic heterogeneity of early Gothic literature. Parts II and III set out to explore this new ground and to support the main argument of this thesis by examining the influence of Greek tragic poetry and myth on the works of two early Gothic novelists and, in many ways, shapers of the genre, William Beckford and Matthew Gregory Lewis. Part II focuses on William Beckford’s Vathek and its indebtedness to Euripides’s Bacchae, and Part III on Matthew Gregory Lewis’s The Monk and its indebtedness to Sophocles’s Oedipus Tyrannus. As is discussed, Beckford and Lewis participated actively in both the Gothic and Hellenic revivals, producing highly imaginative works that blended material from the British and Greek literary traditions.

Teach First Fellows nehmen wie Lehrkräfte eine hohe Verantwortung für die weitere Entwicklung von Kindern und Jugendlichen wahr. Anders als Lehrkräfte verfügen sie jedoch nicht über eine grundständige Ausbildung für ihre spezifische Tätigkeit. Deshalb stellt sich die Frage, inwiefern es gelingen kann, durch eine sorgfältige Auswahl der Fellows, sowie durch eine intensive Kurzqualifizierung gute Voraussetzungen für den Erfolg ihrer Tätigkeit zu schaffen. Die vorliegende Studie evaluiert die Ergebnisse des Qualifizierungsprogramms, das Teach First Deutschland für seine Fellows entwickelt und implementiert hat. Dabei interessiert insbesondere, welches Wissen zur Unterstützung von Lernprozessen, welche Fähigkeiten zur Gestaltung von Unterricht und welche Erwartung von pädagogischer Wirksamkeit innerhalb eines halben Jahres bei den Fellows aufgebaut werden können. Um ein tieferes Verständnis der Wirkweise des Qualifizierungsprogramms zu ermöglichen, wurden neben den Ergebnissen auch dessen Prozesskomponenten einer Bewertung unterzogen. (DIPF/Orig.)

This thesis explores how architectures sense of place is rooted in the natural environment. The built environment has been constructed to protect and sustain human culture from the weathering of nature. Separating experience from the natural environment removes a sense of place and belonging in the natural and reinforces architectural dominance. This separation distinguishes the natural world as an article of spectacle and gives the human experience an unnatural voyeurship to natural changes. By examining the fusion of architectural and natural edges this thesis analyzes how the human experience can reconnect with a naturalistic sense of place through architecture, blending the finite edge where architecture maintains nature, and adapting buildings to the cycles of the environment. Removing dominance of man-made spaces and replacing them with the cohabitation of the edge between built and natural forms.

Mobile devices, smartphones, phablets and tablets, are widely avail‐ able. This is a generation of digital natives. We cannot ignore that they are no longer the same students for which the education system was designed tradition‐ ally. Studying math is many times a cumbersome task. But this can be changed if the teacher takes advantage of the technology that is currently available. We are working in the use of different tools to extend the classroom in a blended learning model. In this paper, it is presented the development of an eBook for teaching mathematics to secondary students. It is developed with the free and open standard EPUB 3 that is available for Android and iOS platforms. This specification supports video embedded in the eBook. In this paper it is shown how to take advantage of this feature, making videos available about lectures and problems resolutions, which is especially interesting for learning mathematics.

The goal of this study is to define the photographic dimension as a transversal notion that accompanies texts and carries out a function that is narrative, discursive and even poetic, and as an unambiguous analytical tool that allows an understanding of the function of the photographic image in contemporary fiction. How does the photographic dimension act within a text of fiction? How does it guide it, define it, and eventually, transform it? How is the space-time element of a text influenced when the photographic dimension affects the heart of the story? How does the status of the photographic image change when it is blended with the fictional text, and how is a text reorganized in light of the photographic dimension? What interpretations are made possible by the analysis of the photographic dimension? Is it possible to narrate and read a photograph without having to see it, or to what extent does a photograph in plain view determine the writing and reading of the story? In short: What writing and reading digressions are caused by the presence of photographs within a literary text; what is their role, for example, in the activation of memory, of a dream-like state or of identity, and what symbolic dimension is introduced?...

An innovative approach to quantify interest rate sensitivities of emerging market corporates is proposed. Our focus is centered at price sensitivity of modeled investment grade and high yield portfolios to changes in the present value of modeled portfolios composed of safe-haven assets, which define risk-free interest rates. Our methodology is based on blended yield indexes. Modeled investment horizons are always kept above one year thus allowing to derive empirical implications for practical strategies of interest rate risk management in the banking book. As our study spans over the period 2002 – 2015, it covers interest rate sensitivity of assets under the pre-crisis, crisis, and post-crisis phases of the economic cycles. We demonstrate that the emerging market corporate bonds both, investment grade and high yield types, depending on the phase of a business cycle exhibit diverse regimes of sensitivity to interest rate changes. We observe switching from a direct positive sensitivity under the normal pre-crisis market conditions to an inverted negative sensitivity during distressed turmoil of the recent financial crisis, and than back to direct positive but weaker sensitivity under new normal post-crisis conjuncture. Our unusual blended yield-based approach allows us to present theoretical explanations of such phenomena from economics point of view and helps us to solve an old controversy regarding positive or negative responses of credit spreads to interest rates. We present numerical quantification of sensitivities, which corroborate with our conclusion that hedging of interest rate risk ought to be a dynamic process linked to the phases of business cycles as we evidence a binary-like behavior of interest rate sensitivities along the economic time. Our findings allow banks and financial institutions for approaching downside risk management and optimizing economic capital under Basel III regulatory capital rules.
