Ich-Erzählen im Medium des Frühdrucks. Narrative und diskursive Strukturen in gedruckten deutschsprachigen Reimerzählungen um 1500 (Hans Folz, Sebastian Brant, Hans Sachs).
No full textMy paper presents three German poems from the late 15th/early 16th cen-tury that formally stand in the tradition of couple rhymed allegorical first-person narratives and thematically deal with the political conditions of their time. The three different authors represent two variants of a certain type of author belonging to the artisan class (Hans Folz, Hans Sachs in Nuremberg) or to the academically educated, bilingual (Latin/German) upper class (Sebastian Brant in Strasbourg) of the urban bourgeois culture. In both cases, they opened up early to the new medium of book printing. Consequently, the para-texts with which all three texts produced directly for print are equipped take on important functions within the new printing medium and the new practise of distance communication that develops from it, aiming above all at the staging of the respective authorship. The three selected case studies high-light the different literary and communicative strategies developed by each author under these auspices. What all three texts have in common, however, is a more or less sophisticated play with the two different discourse levels of the (fictional) narra-tor ego and the (real) author ego. Such a game is at the same time anchored in essen-tial aspects within the socio-cultural environment of the authors and the respective specific literary culture. Thus, in the case of Hans Folz, as in the case of his successor Hans Sachs, the effort to adapt the handed-down medieval traditions and rhetoric models to the new conditions of vernacular communication visibly predominates. Differently, the concept of authorship claimed by Sebastian Brant is characterised by the effort to harmonise the function of the poet as orator and prophet, derived from the humanist tradition, with the instructional tasks fundamental to vernacular poet
A Hybrid Model of Experiential Learning within the Social Virtual World of Second Life
No full textThis study examined how multi-user virtual worlds can enhance learning, by extending and refining a prior VR-based model to include two new constructs: virtual identity, and social constructivism. The fit of the model was analyzed using structural equation modeling (SEM), and the results supported both the extension and the hypothesized refined model. Findings: VR features were found to indirectly impact on the learning outcomes, mediated by the perception of usability and the learning experience. The learning experience was measured by seven individual psychological factors: presence, virtual identity, motivation, cognitive benefits, agentic learning, social constructivism, and reflective thinking. These factors mediated the learning outcomes, measured by the perception of learning effectiveness and satisfaction, and may have a range of implications for the instructional design of learning activities using the virtual world. This research blends a technology acceptance model with the technology-mediated learning perspective to advance the development of a hybrid theoretical framework as a basis for future research into enhanced learning within a social virtual world
Virtual world global collaboration: an educational quest
No full text
Purpose
This research case study shares the partnership between librarians and educators to create a live digital literacy experience at The Quest (Camelot Project), a virtual world medieval simulation. The purpose of the partnership was to gain understanding of the learning elements addressed with a group of participants from across the globe, working at various skill levels and interacting with an immersive virtual world simulation.
Design/methodology/approach
Using field notes, machinima and interviews (participatory action research), the study identifies learning elements within three contexts: technological, pedagogical and content. Learners cycle toward intended learning outcomes in a virtual-world treasure hunt game from the perspective of both designers and participants.
Findings
Findings of the case study illustrate the value of collaboration in a digital game-based learning (DGBL) environment through scaffolding of knowledge and skills in a virtual world. Findings exemplify the experiential learning cycle within a virtual world for constructing learning, and support a proposed new theoretical framework of technology-mediated learning which may help educators in both design and implementation.
Originality/value
As virtual worlds and immersive learning opportunities continue to expand for learners and educators, this study shares the value of experiential learning from the perspective of both the teacher and the learner. Socially constructing knowledge and acquiring skills across distance with a team of librarians and educators are innovative examples of DGBL in an alternative reality setting.

Hybridizing Real and Virtual Experiences: Inquiry-Based Learning Activities to Explore Surface Chemistry
No full textSurface chemistry is a challenging realm for most students because of its abstract nature and numerous associated mathematical equations. Herein we report a set of dedicated sequential inquiry-based learning (IBL) activities enriched with virtual laboratory learning and hands-on instructions. The activities were intended to help students grasp abstract concepts and understand the mathematical equations related to surface chemistry. The activities included two methods for measuring surface tension: the capillary rise method and the drop weight method. In addition, students were guided to observe the adsorption phenomenon and critical micelle concentration (CMC). The activities were implemented in a second-year pharmaceutical chemistry course for pharmacy undergraduate students. Feedback from the students indicated that the activities could nurture their interest in the topics. Moreover, we have proven that hybridizing virtual learning and hands-on learning in IBL is viable and could offer positive effects on students’ learning. We advocate the use of virtual laboratories to support IBL activities in the postpandemic era.</p
The Impact of strategic implementation on the employees and contractors of the Hewlett-Packard Company.
No full textConducted within the global corporation of the Hewlett-Packard Company, (HP),this research examines employee and contractor responses to strategic implementation. The research environment is a relatively small UK group withinthe corporation that has continuously experienced significant change as new strategies were implemented. Employee and contractor responses to three separate cycles of change are analysed together with data drawn from the wider corporation by using a psychological contract framework, semi-structured interviewing, a research diary and secondary data from the literature and electronic sources. The research is essentially qualitative but draws on quantitative data where appropriate. A case study approach within an action research paradigm is the chosen methodology to allow consideration and triangulation of multiple sources of data relevant to the natural workplace setting. The research has confirmed a change from old or original psychological contracts to new contracts where employees and contractors are more insecure in, and more cynical of, their employment. This change is perceived as a
violation of their psychological contract and is causing employees and contractors to adopt a more mercenary approach to their employment with HP. The special bond between HP and its employees generated by the values and
egalitarian working environment created by its founders has been broken by new leadership. Acquisition of the Compaq Computer Company has further impacted employees and contractors resulting in declining morale and increasing scepticism about its proposed benefits. Indeed the very legitimacy of the acquisition and the leadership of HP are being questioned as HP changes to a new form. According to the founders, the values established that made HP successful in its first fifty years were expected to continue for at least another fifty years. This research shows how changing these values has collectively impacted
employees and contractors resulting in a major threat to the continuing existence of HP in its present form
VIBRATIONAL OVERTONE SPECTROSCOPY OF CYCLOHEXADIENE IRON TRICARBONYL AND 1,3-CYCLOHEXADIENE
No full textAuthor Institution: Department of Chemistry and Center for Photochemical Sciences, Bowling Green State University; Department of Chemistry, University of Manitoba; Department of Chemistry, University of OtagoVibrational overone spectra of cyclohexadiene iron tricarbonyl and 1,3-cyclohexadiene for both gas and liquid phases have been recorded and compared for the first, second, third and fourth overtone regions. The cyclohexadiene iron tricarbonyl spectrum exhibits significant changes compared to the spectrum of unbound ligand indicating that complexation with iron tricarbonyl strongly affects the structure and properties of 1,3-cyclohexadiene. The assignments have been made for the uncomplexed ligand based on the Harmonically Coupled Anharmonic Oscillators (HCAO) model. Preliminary assignments have been suggested for the complex. The proposed assignments are suported by the results of ab initio Hartree-Fock calculations
CONTINUING RESEARCH INTO THE OVERTIONE SPECTRA OF TRIMETHYL AMINE
No full textAuthor Institution: Department of Chemistry, University of Manitoba; Department of Chemistry, University of OtagoThe CH bonds in trimethylamine that lie trans to the nitrogen lone pair are known to be much longer than the gauche CH. This is the most extreme known example of the trans lone pair effect, depicted by frontier molecular orbital theory as a delocalization of the lone pair electrons into the anti-bonding orbitals of the trans CH bonds. The spectrum of trimethylamine has been the subject of much study over years, ranging from the fundamental infra-red of trimethyl amine and selectively decterated derivatives to the overtone spectra of trimethylamine. We have collected the overtone spectra (1st -5th) of some deuterated derivatives in order to improve the assignment of the overtone peaks. A harmonically coupled anharmonic oscillator local mode mathematical model has been used to predict the intensity of the absorptions in the overtone regions

Algorithm Development for Land Surface Temperature Retrieval: Application to Chinese Gaofen-5 Data
No full textLand surface temperature (LST) is a key variable in the study of the energy exchange between the land surface and the atmosphere. Among the different methods proposed to estimate LST, the quadratic split-window (SW) method has achieved considerable popularity. This method works well when the emissivities are high in both channels. Unfortunately, it performs poorly for low land surface emissivities (LSEs). To solve this problem, assuming that the LSE is known, the constant in the quadratic SW method was calculated by maintaining the other coefficients the same as those obtained for the black body condition. This procedure permits transfer of the emissivity effect to the constant. The result demonstrated that the constant was influenced by both atmospheric water vapour content (W) and atmospheric temperature (T0) in the bottom layer. To parameterize the constant, an exponential approximation between W and T0 was used. A LST retrieval algorithm was proposed. The error for the proposed algorithm was RMSE = 0.70 K. Sensitivity analysis results showed that under the consideration of NEΔT = 0.2 K, 20% uncertainty in W and 1% uncertainties in the channel mean emissivity and the channel emissivity difference, the RMSE was 1.29 K. Compared with AST 08 product, the proposed algorithm underestimated LST by about 0.8 K for both study areas when ASTER L1B data was used as a proxy of Gaofen-5 (GF-5) satellite data. The GF-5 satellite is scheduled to be launched in 2017
Tendências e implicações epistemológicas de produções científicas de pós-graduação em educação física relacionadas à obesidade
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2009.Considerando que a concepção de obesidade predominante no campo da Saúde vem sendo reproduzida no campo da Educação Física, buscamos neste estudo outras possibilidades de investigação deste fenômeno. A partir da utilização de técnicas para a identificação das abordagens metodológicas e dos elementos técnicos, epistemológicos e teóricos das investigações de pós-graduação em Educação Física que estudaram a obesidade, abordamos criticamente os resultados da análise realizada nessas produções levando em consideração a concepção da determinação social do processo saúde-doença, desenvolvida pelo campo da Saúde Coletiva e Epidemiologia Crítica. Com vistas a melhor compreender este fenômeno, destacamos elementos fundamentais da perspectiva histórica da alimentação e sua relação dialética com o processo de obesidade e com as ações privilegiadas pelo campo da Educação Física. Os resultados apontam que, das trinta e três pesquisas analisadas, ocorreu o predomínio da abordagem metodológica empírico-analítica, estando presente em trinta e duas delas (96,96%). Em apenas uma pesquisa identificamos a abordagem metodológica fenomenológica-hermenêutica (3,04%) e nenhuma pesquisa utilizou a abordagem críticodialética. A partir da identificação de que a vertente metodológica predominante é fundamentada pela lógica causal, considerando a obesidade meramente como correlação entre o aumento da ingestão calórica e diminuição do gasto energético, e da constatação de que as prescrições para que seja evitada ou revertida estão pautadas na reeducação alimentar e na atividade física, buscamos evidenciar os condicionamentos sociais que determinam as dimensões deste quadro. Um olhar para a construção histórica da obesidade como problema médico e social e sua contextualização como um fenômeno com profundas determinações políticas e econômicas, buscamos recolocar a complexidade deste fenômeno no âmbito da produção do conhecimento. Dessa maneira compreendemos que existem outras possibilidades de relações entre a obesidade e a Educação Física, por meio de perspectivas crítico-pedagógicas deste campo, e nos contrapomos ao reducionismo no trato das práticas corporais apenas como atividade física
