Autonomie und Verantwortung im Studium
Authors: Liebermann Sascha 
Published: November 2016

Zusammenfassung
In den vergangenen Jahren haben manche Bundesländer die allgemeine Anwesenheitspflicht in Lehrveranstaltungen, sofern sie in Hochschulgesetzen geregelt war, aufgehoben, nachdem sie zuvor schon durch minis-terielle Erlasse außer Kraft gesetzt worden war. Diese Entscheidung, in Nordrhein Westfalen mit dem Hochschulzukunftsgesetz verbunden, hat überraschend drastische Kritik hervorgerufen. Mit Aufhebung der Anwesenheitspflicht sei die Universität als solche überflüssig geworden, die Qualität der Lehre sei gefährdet, kontinuierliche Fortentwicklung einer Fragestellung sei nicht mehr möglich, da die Gefahr bestünde, in jeder Sitzung einer neuen Konstellation von Teilnehmern gegenüberzustehen. Der Beitrag untersucht ausgewählte Stellungnahmen auf ihre Argumentation und die darin rekonstruierbaren Deutungsmuster zu Autonomie der Lebenspraxis. Alle offenbaren gleichermaßen ein unsicheres bis drastisch misstrauendes Verhältnis zu Autonomie, das für die Lehre folgenreich und erklärungsbedürftig ist, muss sie – für ein wissenschaftliches Studium in herausgehobenem Maße – auf diese Autonomie setzen.

ABSTRACT
ATHLETE TRAINING SHOULD PROCEED FROM THOROUGH AND SYSTEMATIC PERIODIZED PLANS FOR THE IMPLEMENTATION OF TRAINING LOADS. THE TIME-COURSE OF TRAINING SHOULD INCLUDE PERIODS OF HIGH LOADS PUNCTUATED BY REDUCED LOADS AND REST. AS THERE ARE A WIDE VARIETY OF MEANS AND METHODS USED FOR THE IMPLEMENTATION OF LOADS, THERE ARE NUMEROUS MEANS AND METHODS FOR ENHANCING RECOVERY AND ADAPTATION (RA). RA FROM ATHLETE TRAINING ARE POORLY UNDERSTOOD AND IN NEED OF A MODEL OR FRAMEWORK TO ADVANCE OUR ABILITY TO SYSTEMATICALLY COMPLEMENT TRAINING WITH APPROPRIATE MODALITIES.

Published: November 2016

Background: This study evaluates occurrence of progressive bone loss (PBL) around implants with different implant surfaces.Methods: Retrospective examination of 2,517 implants was performed in 903 patients, including 1,147 anodized‐surface implants in 454 patients and 1,370 resorbable blasting media (RBM)‐surface implants in 449 patients, which were placed from January 2006 to December 2010. Through regular check‐up radiographs and records, presence of PBL (up to >50% of fixture length) was investigated. Implant removal for any reason was regarded a failure.Results: In total, 2,186 implants (979 anodized implants and 1,207 RBM implants) in 793 patients were included in this study. PBL was more frequently observed among anodized implants (n = 36 in 21 patients; 4%) than among RBM implants (n = 19 in 14 patients; 2%), and this difference was statistically significant (P <0.001). Occurrence of PBL was significantly influenced by surface modification and implant diameter (odds ratio [OR] of anodized surface = 4.40, 95% confidence interval [CI] = 1.78 to 10.89, P = 0.001; OR of wide implants = 9.62, 95% CI = 1.13 to 81.68, P = 0.038; determined by mixed‐effects logistic regression analysis with random patient effect). However, total survival rate was significantly influenced by implant diameter and not by surface modification (P = 0.019), although effect of implant diameter was observed to be significant on anodized implants (P = 0.030).Conclusion: Implant surface modification and implant diameter are significantly associated with occurrence of PBL.

Published: November 2016

Background: A possible association between periodontitis and obstructive sleep apnea (OSA) has been suggested. The aim of this study is to compare periodontitis prevalence between controls and patients with OSA by assessing clinical periodontal parameters and gingival crevicular fluid (GCF) levels of interleukin (IL)‐1β, tumor necrosis factor (TNF)‐α, and high‐sensitive C‐reactive protein (hs‐CRP); serum hs‐CRP was also sampled.Methods: A case‐control study was performed that included 163 individuals: 83 individuals (18 females and 65 males) with OSA and 80 non‐OSA individuals (23 females and 57 males) as controls. The test group was classified according to OSA severity. Clinical periodontal measurements were recorded, and GCF samples were collected. GCF hs‐CRP, IL‐lβ, and TNF‐α levels were analyzed using an enzyme‐linked immunosorbent assay method. Serum hs‐CRP was measured by latex‐enhanced immunoturbidimetric assay.Results: Prevalence of periodontitis in the OSA group (96.4%) was significantly higher than in the control group (75% [P <0.001]). Severe periodontitis prevalence was higher in the OSA group than control group. All periodontal clinical parameters and GCF IL‐lβ concentrations were significantly higher in patients with OSA than in controls (P = 0.001). No significant differences were found between the mild OSA and moderate‐to‐severe OSA groups. Additionally, there was no significant difference in GCF TNF‐α and hs‐CRP levels between the groups (P >0.05). Serum hs‐CRP levels were significantly higher in patients with OSA. A significant correlation was found between GCF IL‐1β and all clinical parameters.Conclusions: Results demonstrated higher prevalence of periodontitis and higher levels of GCF IL‐1β and serum hs‐CRP in patients with OSA. However, there is still a need for randomized clinical trials testing oral care interventions.

Tokom prvih godina života dete uspostavlja različite socio-emocionalne odnose koji oblikuju njegov psiho-socijalni razvoj. Pored prihvatanja od strane članova porodice, u socijalizaciji deteta od posebnog značaja su odnosi i prihvaćenost od strane vršnjaka. Socijalno kompetentno dete koristi različite podsticaje iz okoline, kao i svoje lične veštine i interesovanja, za učestvovanje u zajednici kojoj pripada. Razvoj i učenje deteta značajno su otežani ukoliko podsticaji za interakcijom izostaju ili duže vreme bivaju ometani neadekvatnim ponašanjem deteta i/ili vršnjačkim neprihvatanjem. Sa namerom da se preventivno deluje, dizajnirano je istraživanje u pet pripremnih grupa jedne predškolske ustanove u Vojvodini. Cilj istraživanja bile su veze između socijane kompetentnosti dece (N=120) i prihvaćenosti u grupi vršnjaka, te njihove sklonosti ka antisocijalnom ponašanju. Nalazi dobijeni skaliranjem i sociometrijom pokazuju da se predškolci međusobno značajno razlikuju u prihvaćenosti, socijalnom i antisocijanom ponašanju, pri čemu je uspostavljena značajna pozitivna korelacija između socijalne kompetentnosti i broja godina provedenih u ustanovi, dok su devojčice procenjene kao prihvaćenije i kompetentnije. Primećena je i značajna negativna povezanost između odbijanja i socijalne kompetentnosti kod dečaka, te antisocijalnog ponašanja i procenjene kompetentnosti dece među predškolcima ukupno, bez obzira na pol. Ustanovljeno je da antisocijalno ponašanje nije značajnije povezano sa brojem godina provedenih u ustanovi. Omogućavanje podsticajnih uslova za jačanje socijalne kompetentnosti i rano identifikovanje dece kojoj je potrebna dodatna podrška za uspostavljanje i građenje odnosa sa vršnjacima temeljni su zadaci svih koji su u kontaktu sa decom predškolskog uzrasta, posebno onih koji deluju u okviru predškolskih ustanova.

Attracting, preparing, and retaining under-represented populations in rural and remote Alberta-North communities
Authors: Steel Nancy , Fahy Patrick J. 
Published: November 2016

<p>For several years, the government of the western Canadian province of Alberta has drafted policies and conducted research on the problem of populations under-represented in adult education. This Alberta-North and Athabasca University study, funded by the Alberta government’s Innovation Fund, uses the advice and educational experiences of northern former and present students, and of other community members, to identify ways of better attracting, preparing, and retaining under-represented populations in northern Alberta communities through provision and training in the use of distance delivery methods.</p><p>The research reported here commences with a review of the literature to investigate the following: 1) the contribution distance education makes globally to learning access in remote areas (and resulting economic growth for under-served populations); 2) how support is provided to retain isolated students; and 3) the help needed to assist remote students to complete distance programs. Community consultations with social service and education agencies in three communities were conducted in order to obtain their perspectives about what helps to attract and support students to educational programs and the barriers students typically encounter, which might be mitigated by distance methods. Finally, a survey was designed and distributed in 87 Alberta-North communities in northern Alberta and across Canada’s Northwest Territories to add perspective to the consultation results.</p>
Role engagement and anonymity in synchronous online role play
Authors: Cornelius Sarah , Gordon Carole , Harris Margaret 
Published: November 2016

<p>Role play activities provide opportunities for learners to adopt unfamiliar roles, engage in interactions with others, and get involved in realistic tasks. They are often recommended to foster the development of soft skills and a wider perspective of the world. Such activities are widely used as an online teaching approach, with examples ranging from the simple use of email to the employment of virtual worlds and Web 2.0 technologies.</p><p>This paper provides a case study of a role play activity which employs real-time anonymous discussion forums and aims to improve our understanding of effective role play and the impact of anonymity. This role play has been effective in educating learners about different perspectives on the issue of Quality in Further Education. The context and implementation of the role play are outlined, and the learners’ interactions and experiences are explored using an investigative analysis of discussion transcripts and semi-structured interviews with participants. The findings suggest that role engagement and anonymity are important components for success in synchronous online role play. Evidence is presented that provides an insight into the factors which encourage role engagement, including prior experiences and contributions from peers. The impact of anonymity is also explored since many participants did not regard the study environment as real and attempted to identify their peers.</p><p> </p>
Learner analysis framework for globalized e-learning: A case study
Authors: Saxena Mamta 
Published: November 2016

<p>The shift to technology-mediated modes of instructional delivery and increased global connectivity has led to the rise in globalized e-learning programs. Educational institutions face multiple challenges as they seek to design effective, engaging, and culturally competent instruction for an increasingly diverse learner population. The purpose of this study was to explore strategies for expanding learner analysis within the instructional design process to better address cultural influences on learning. A case study approach leveraged the experience of practicing instructional designers to build a framework for culturally competent learner analysis.</p><p> </p><p>The study discussed the related challenges and recommended strategies to improve the effectiveness of cross-cultural learner analysis. Based on the findings, a framework for conducting cross-cultural learner analysis to guide the cultural analysis of diverse learners was proposed. The study identified the most critical factors in improving cross-cultural learner analysis as the judicious use of existing research on cross-cultural theories and joint deliberation on the part of all the participants from the management to the learners. Several strategies for guiding and improving the cultural inquiry process were summarized. Barriers and solutions for the requirements are also discussed.</p>

Published: November 2016

<p>The present study was carried out to determine the motivating factors for enrolling in an engineering study programme in open and distance learning (ODL) and the factors that affect the students’ performance. The study was conducted with two convenient samples of students following distance learning courses in engineering technology, conducted by the Open University of Sri Lanka and leading to the award of diploma or degree in Engineering Technology. One sample consisted of students who failed to qualify for sitting the year-end examination and the other consisted of successful students.</p><p>The study showed that many students opt to follow the programme without knowing the relevance of the study programme for them. Most of the students (53%) had taken the courses believing that they could obtain a recognized degree. The students with secondary education qualifications in the mathematics stream were found to be successful, provided that they had selected the ODL programmes with an understanding of the nature of the ODL system, the percentages being 61 with 4 passes, 75 with 3 passes, and 20 with 2 passes at the General Certificate in Education (Advanced Level) examination.</p><p>All successful students were of the opinion that the course delivery methods should be improved, especially face-to-face teaching, laboratory classes, and assignments.</p><p> </p><p> </p>
Rapport in distance education
Authors: Murphy Elizabeth , Rodríguez-Manzanares María A. 
Published: November 2016

<p>Rapport has been recognized as important in learning in general but little is known about its importance in distance education (DE). The study we report on in this paper provides insights into the importance of rapport in DE as well as challenges to and indicators of rapport-building in DE. The study relied on interviews with 42 Canadian high-school DE teachers. Findings revealed that rapport is necessary in DE because of the absence of face-to-face communication. Challenges to building rapport relate to the geographic dispersion of students, the asynchronous nature of DE, teacher workload, limits of the software, teachers and students not seeing the need for rapport, and DE traditions. We identified six categories of rapport-building in DE as follows: <em>Recognizing the person/individual; Supporting and monitoring; Availability, accessibility, and responsiveness; Non text-based interactions; Tone of interactions; Non-academic conversation/interactions</em>. We break the categories into subcategories and provide indicators for each one. The indicators might also be used in contexts of DE teacher professional development as a springboard for discussion, or, more prescriptively, as guides to DE teacher behaviour. A follow-up study using a more fine-grained focus on specific indicators might provide insights into specific rapport-related behaviours.</p>
Mobile microblogging: Using Twitter and mobile devices in an online course to promote learning in authentic contexts
Authors: Hsu Yu-Chang , Ching Yu-Hui 
Published: November 2016

This research applied a mixed-method design to explore how best to promote learning in authentic contexts in an online graduate course in instructional message design. The students used Twitter apps on their mobile devices to collect, share, and comment on authentic design examples found in their daily lives. The data sources included tweets (i.e., postings on Twitter), students’ perceptions about mobile microblogging activities, and self-reported Twitter usage. Based on the tweet analysis, we found that the students appropriately applied the design principles and design terms in their critique of design examples. While the students were mainly engaged in assignment-relevant activities, they spontaneously generated social tweets as they related peers’ authentic design examples to their own life experiences. Overall, they had positive perceptions toward the mobile microblogging activities. The students also indicated that the design examples shared by peers through mobile microblogging inspired their own message design work. We synthesized instructional design suggestions and challenges for educators interested in incorporating mobile microblogging in their instructional settings.<p style="text-indent: 0px; margin: 0px;"> </p><p> </p>

Authors: Cheng Jinn-Shing , Huang Echo , Lin Chuan-Lang 
Published: November 2016

Due to the constant performance upgrades and regular price reductions of mobile devices in recent years, users are able to take advantage of the various devices to obtain digital content regardless of the limitations of time and place. The increasing use of e-books has stimulated new e-learning approaches. This research project developed an e-book hub service on a cloud computing platform in order to overcome the limitations of computing capability and storage capacity that are inherent in many mobile devices. The e-book hub service also allows users to automatically adjust the rendering of multimedia pages at different resolutions on terminal units such as smartphones, tablets, PCs, and so forth. We implemented an e-book hub service on OpenStack, which is a free and open-source cloud computing platform supported by multiple large firms. The OpenStack platform provides a large-scale distributed computing environment that allows users to build their own cloud systems in a public, private, or hybrid environment. Our e-book hub system offers content providers an easy-to-use cloud computing service with unlimited storage capacity, fluent playback, high usability and scalability, and high security characteristics to produce, convert, and manage their e-books. The integration of information and communication technologies has led the traditional publishing industry to new horizons with abundant digital content publications. Results from this study may help content providers create a new service model with increased profitability and enable mobile device users to easily get digital content, thereby achieving the goal of e-learning.<br /><br />
La forma del límite en las ciudades medias españolas
Authors: Zúñiga Sagredo Irene 
Published: November 2016

RESUMEN:La ciudad multiforme es también la ciudad con ausencia de forma en el sentido tradicional de carácter limitado, abarcable y sobre todo ordenado. La ciudad contemporánea de tamaño medio tiene formas ilimitadas, inabarcables y con estructuras desordenadas que ocupan el espacio circundante y sobrepasan las delimitaciones administrativas. El presente trabajo forma parte de la tesis doctoral de la autora titulada “El Borde Urbano. Un acercamiento paisajístico y funcional de los límites del suelo urbanizado en las ciudades medias españolas”, donde se definen los diferentes tipos de borde urbano. Para ello se establecen las relaciones entre los diferentes usos y paisajes que aparecen a lo largo de este límite. Con estas relaciones se establecen cuatro tipologías según diferentes aspectos; las barreras como condicionantes de la forma, cómo el límite histórico deja una huella en el límite actual de la ciudad, la manera en que la forma condiciona las relaciones entre ciudad y no ciudad y la imagen formal que muestra la ciudad al exterior. ABSTRACT: The multiform city is the city without defined shape in the traditional meaning of bounded, measurable and organized layout. The medium size contemporary city has unlimited forms and unorganized structures that sprawl around the territory beyond the administrative boundaries. This research is part of the author's PhD thesis titled “The Urban Boundary. A landscape and functional approach to the boundaries of urban land in the Spanish medium-sized cities” where different types of urban boundaries are defined. Relationships between the different uses and landscapes appearing along this boundary are set in order to identify four typologies according to different aspects; barriers as constraints to urban morphology, how the historical boundaries are part of the contemporary urban fringe, how the boundary morphology determines the relations between city and no city, and the image that the city offers the countryside.
Optimization of Gravity-Stable Surfactant Flooding
Authors: Lu Jun , Pope Gary A. 
Published: November 2016

SummaryHorizontal surfactant floods are inherently unstable without mobility control. However, a vertical surfactant flood can be stabilized by gravity if the velocity is below the critical velocity. A modified stability theory was validated by comparison with a series of surfactant-displacement experiments. These experiments also demonstrate that the critical velocity can be increased by optimizing the viscosity of the microemulsion that forms when the surfactant solution mixes with the oil in the porous medium. The microemulsion viscosity is sensitive to formulation variables such as the amount and type of co-solvent added to the surfactant solution. By changing surfactant components, co-solvents, and the concentration of the co-solvents, we were able to successfully control the microemulsion viscosity at optimum salinity to optimize the critical velocities in each surfactant flood. The experiments with optimized microemulsions show that the surfactant-flood velocity can be significantly increased and still recover nearly 100% of the oil.
