Doordat verhevigde concurrentiekrachten bedrijven dwingen om sneller te innoveren als voorheen wordt innovatie gezien als de belangrijkste uitdaging voor zowel publieke als private organisaties in de huidige tijd. Omdat elk nieuw product of innovatie start met 1 persoon in de organisatie die een vernieuwend idee heeft en dit idee in actie wil omzetten, is het van belang om het innovatiepotentieel van alle werknemers in de organisatie te benutten. Een belangrijke rol hierin is weggelegd voor de directe leidinggevende die met zijn gedrag in staat is om het innovatieve werkgedrag (IWG) van zijn ondergeschikten te stimuleren. In dit rapport is onderzocht of dienend leiderschap (DL), een leiderschapsstijl die in het bijzonder opvalt door de nadruk die hierin wordt gelegd op de emotionele, relationele en morele dimensies van leiderschap, IWG van werknemers bevordert. De relatie tussen deze leiderschapsstijl en individueel IWG is niet eerder onderzocht maar door aanwijzingen in de literatuur en empirisch onderzoek naar verwante concepten, was de verwachting dat DL IWG positief zou beïnvloeden en dat er een (gedeeltelijk) mediërende rol zou zijn weggelegd voor het gevoel van psychologische veiligheid (PV) dat werknemers ervaren in hun werkteam. Aan de hand van een open online vragenlijst met gestructureerde vragen zijn 226 werknemers, werkzaam in Nederland en Vlaanderen in een variëteit aan bedrijfstakken, ondervraagd. Middels de vragenlijst is in kaart gebracht: de perceptie van werknemers van het DL van hun directe leidinggevende, hoe groot het gevoel van PV is dat werknemers ervaren in hun werkteam en de mate waarin werknemers van zichzelf vinden dat zij IWG vertonen. Uit het onderzoek blijkt dat naarmate werknemers hun leidinggevende meer als dienend leider percipiëren zij zichzelf significant hoger scoren op IWG. Van de 8 dimensies waar DL uit bestaat (empowerment, accountability, nederigheid, dienstbaarheid, authenticiteit, moed, vergeving en rentmeesterschap) blijken enkel de dimensies empowerment en authenticiteit een significante invloed uit te oefenen op IWG boven de bijdragen van de andere DL-dimensies. Uit het onderzoek blijkt ook dat naarmate werknemers hun leidinggevende meer als dienend leider percipiëren, zij een significant hoger gevoel van PV in hun werkteam rapporteren. Hoewel er ook een significant positief verband is gevonden tussen het gevoel van PV dat werknemers ervaren in hun werkteam en de scores die zij zichzelf geven op IWG, blijkt PV geen mediërende rol te spelen in de relatie tussen DL en IWG. DL is in het onderzoek een dubbel zo sterke voorspeller gebleken van IWG dan PV. Aanbevelingen voor toekomstig onderzoek naar de relatie tussen DL, PV en IWG zijn onder andere dat PV en IWG op groepsniveau worden onderzocht in plaats van op individueel niveau, dat autonomie en zelfvertrouwen als variabelen worden meegenomen in het onderzoek en dat ook gebruik wordt gemaakt van beoordelingen van leidinggevenden voor wat betreft IWG in plaats van enkel van zelfbeoordeling. Organisaties die het belangrijk vinden dat het innovatiepotentieel van al hun werknemers wordt aangesproken, hebben leidinggevenden nodig die authentiek zijn en die hun ondergeschikten kunnen empoweren. Praktische aanbeveling is dan ook dat gedragingen van leidinggevenden die te maken hebben met empowerment en authenticiteit door de organisatie gestimuleerd worden. Het betreft hier onder andere de volgende leiderschapsgedragingen: werknemers aanmoedigen zich persoonlijk te ontwikkelen, werknemers het gevoel geven dat ze bekwaam zijn, sturen op het nemen van zelfstandige beslissingen (empowerment), professionele rollen ondergeschikt maken aan wie men is als persoon, doen wat beloofd is, eerlijk zijn en zich kwetsbaar durven opstellen (authenticiteit).

Das Institut für Ökonomische Bildung (IÖB) an der Carl von Ossietzky Universität Oldenburg ist u.a. mit der wissenschaftlichen Durchführung des Projekts „Ökonomische Bildung online“ befasst, mit dem die Entwicklung eines vollständigen internetbasierten Studiengangs, differenzierter Fort- und Weiterbildungsprofile für Lehrkräfte an allgemein bildenden Schulen und die Vorbereitung des Exports des Studiengangs nach Russland erreicht werden soll. Ein vertraglich fixiertes Hauptaugenmerk bei der Entwicklung dieser Angebote liegt auf der Nachhaltigkeit, d.h. nach Ablauf der Projektförderdauer (7/2001–12/2004) sollen sich die Produkte auf dem wachsenden Bildungsmarkt selbst refinanzieren. Wie versucht werden soll die Nachhaltigkeit zu erreichen, ist Gegenstand dieses Artikels. Im Mittelpunkt stehen dabei Maßnahmen der Qualitätssicherung, die m.E. aber nicht bei der Betrachtung der Produkte an sich, d.h. der Inhalte und Kurse selbst beschränkt bleiben kann, sondern auch die Ausrichtung an der Marktsituation, die Bedürfnisse der Zielgruppen, die Kooperationsbeziehungen, die Finanzierung und die Technik ins Blickfeld nehmen muss.

Im Wintersemester 1996 wurde am Lehrgebiet Praktische Informatik I mit einigen wenigen Kursen und ebenso wenig Studierenden die Virtuelle Universität (VU) der FernUniversität in Hagen gestartet. Heute arbeiten mehr als 25.000 Nutzer aktiv mit dieser Plattform und können aus über 300 Kursen aller Fachbereiche ihr individuelles Studienprofil auswählen. Die Virtuelle Universität (VU) hat allerdings nicht nur enorme Veränderungen von Lehren und Lernen bewirkt, auch die Organisation als Ganzes erfährt inzwischen durch die VU einen Strukturwandel. Viele Publikationen beschäftigen sich mit den technologischen, didaktischen und auch juristischen Aspekten des Wandels; aber kaum jemand beschreibt die kompletten Auswirkungen durch den Einsatz eines solchen Systems und doch wird genau danach sehr häufig gefragt. Nicht nur Studierende, auch Lehrende, Verwaltungsangestellte und Techniker werden vor neue Herausforderungen gestellt. Im folgenden Papier werden die Erfahrungen aus dem Projekt Virtuelle Universität der FernUniversität in Hagen zusammengefasst. Am Beispiel des Projektes soll gezeigt werden, wie ein Initiativprojekt eine ganze Organisation in seinen Bann zog und vielfältige Veränderungen in allen Bereichen bewirkt hat. (DIPF/Orig.)

The aim of this paper is to present the models and the strategies of adoption of e-learning in a group of European universities, most of them located in the regions called “the four motors of Europe” (Baden-Württenberg, Catalunya, Lombardy and Rhône-Alpes) and in Switzerland. Our analysis focuses on four dimensions: the rationale behind the introduction of e-learning, the organisation of the activities and, in particular, the existence of a university centre for e-learning, the type of activities, and, finally, the type of public reached by e-learning. The majority of campus universities in our sample introduced e-learning to improve the quality of education of their students and, for the most part, as a support for existing courses. Some of the campus universities went even further insofar as they have introduced some online courses into their curricula. This has led to forms of cooperation where different universities share some of their courses. Finally, a small number of campus universities have included as part of their educational offer full distance degree programs which can be attended also by non residential students. The above cases show that there is no general move from campus universities towards distance education, but rather a more selective behaviour. Thus we conclude that e-learning, although it is undoubtedly spreading in both distance and presence universities, is not yet bringing fundamental changes in the institutions themselves. E-learning is at the moment integrated into the existing organization and educational offer. (DIPF/Orig.)

Im Rahmen des BMBF-Leitprojektes „Virtuelle Fachhochschule“ werden in einem interdisziplinären Team an der TFH Berlin 12 Online-Studienmodule für die Bachelor-Studiengänge Medieninformatik und Wirtschaftsingenieurwesen produziert. Unter der Leitung langjährig in der Lehre erfahrener Professorinnen und Professoren wurden mediendidaktisch anspruchsvolle Online-Kurse entwickelt. Das didaktische Design war neben der Produktentwicklung konsequent auf die Entwicklung eines effizienten Produktionsprozesses für multimediales Lernmaterial ausgerichtet. Das Online-Lernmaterial ist so modular aufgebaut, dass Teile daraus in die Präsenzlehre integrierbar sind. Der mehrstufige, abgestimmte Produktionsprozess kann für die kostengünstige Erstellung von Online-Material in anderen Fächern genutzt werden. Das Verfahren ist darüber hinaus erweiterbar. Diese Entwicklung leistet einen Beitrag zur nachhaltigen Integration von Online- Lehr- und Lernangeboten im Hochschulbereich.(DIPF/Orig.)

We present a case for using Global Community Innovation Platforms (GCIPs), an approach to improve innovation and knowledge exchange in international scientific communities through a common and open online infrastructure. We highlight the value of GCIPs by focusing on recent efforts targeting the ecological sciences, where GCIPs are of high relevance given the urgent need for interdisciplinary, geographical, and cross-sector collaboration to cope with growing challenges to the environment as well as the scientific community itself. Amidst the emergence of new international institutions, organizations, and meetings, GCIPs provide a stable international infrastructure for rapid and long-term coordination that can be accessed by any individual. This accessibility can be especially important for researchers early in their careers. Recent examples of early-career GCIPs complement an array of existing options for early-career scientists to improve skill sets, increase academic and social impact, and broaden career opportunities. We provide a number of examples of existing early-career initiatives that incorporate elements from the GCIPs approach, and highlight an in-depth case study from the ecological sciences: the International Network of Next-Generation Ecologists (INNGE), initiated in 2010 with support from the International Association for Ecology and 20 member institutions from six continents.

We approach marketization and commodification of adult education from multiple lenses including our personal narratives and neoliberalism juxtaposed against the educational philosophy of the Progressive Period. We argue that adult education occurs in many arenas including the public spaces found in social movements, community-based organizations, and government sponsored programs designed to engage and give voice to all citizens toward building a stronger civil society. We conclude that only when adult education is viewed from the university lens, where it focuses on the individual and not the public good, does it succumb to neoliberal forces. (DIPF/Orig.)

Context. Four clusters of red supergiants have been discovered in a region of the Milky Way close to base of the Scutum-Crux Arm and the tip of the Long Bar. Population synthesis models indicate that they must be very massive to harbour so many supergiants. If the clusters are physically connected, this Scutum Complex would be the largest and most massive star-forming region ever identified in the Milky Way. Aims. The spatial extent of one of these clusters, RSGC3, has not been investigated. In this paper we explore the possibility that a population of red supergiants could be located in its vicinity. Methods. We utilised 2MASS JHKS photometry to identify candidate obscured luminous red stars in the vicinity of RSGC3. We observed a sample of candidates with the TWIN spectrograph on the 3.5-m telescope at Calar Alto, obtaining intermediate-resolution spectroscopy in the 8000−9000 Å range. We re-evaluated a number of classification criteria proposed in the literature for this spectral range and found that we could use our spectra to derive spectral types and luminosity classes. Results. We measured the radial velocity of five members of RSGC3, finding velocities similar to the average for members of Stephenson 2. Among the candidates observed outside the cluster, our spectra revealed eight M-type supergiants at distances <18′ from the centre of RSGC3, distributed in two clumps. The southern clump is most likely another cluster of red supergiants, with reddening and age identical to RSGC3. From 2MASS photometry, we identified four likely supergiant members of the cluster in addition to the five spectroscopically observed. The northern clump may be a small cluster with similar parameters. Photometric analysis of the area around RSGC3 suggests the presence of a large (>30) population of red supergiants with similar colours. Conclusions. Our data suggest that the massive cluster RSGC3 is surrounded by an extended association, which may be very massive ( ≳ 105 M⊙). We also show that supergiants in the Scutum Complex may be characterised via a combination of 2MASS photometry and intermediate-to-high-resolution spectroscopy in the Z band.

A growing number of online journals and academic platforms are adopting light peer review or 'publish then filter' models of scholarly communication. These approaches have the advantage of enabling instant exchanges of knowledge between academics and are part of a wider search for alternatives to traditional peer review and certification processes in scholarly publishing. However, establishing credibility and identifying the correct balance between communication and scholarly rigour remains an important challenge for digital communication platforms targeting academic communities. This paper looks at a highly influential, government-backed, open publishing platform in China: Science Paper Online, which is using transparent post-publication peer-review processes to encourage innovation and address systemic problems in China's traditional academic publishing system. There can be little doubt that the Chinese academic publishing landscape differs in important ways from counterparts in the United States and Western Europe. However, this article suggests that developments in China also provide important lessons about the potential of digital technology and government policy to facilitate a large-scale shift towards more open and networked models of scholarly communication.

In this work, we describe a system, which recognises open vocabulary, isolated, online handwritten Tamil words and extend it to recognize a paragraph of writing. We explain in detail each step involved in the process: segmentation, preprocessing, feature extraction, classification and bigram-based post-processing. On our database of 45,000 handwritten words obtained through tablet PC, we have obtained symbol level accuracy of 78.5% and 85.3% without and with the usage of post-processing using symbol level language models, respectively. Word level accuracies for the same are 40.1% and 59.6%. A line and word level segmentation strategy is proposed, which gives promising results of 100% line segmentation and 98.1% word segmentation accuracies on our initial trials of 40 handwritten paragraphs. The two modules have been combined to obtain a full-fledged page recognition system for online handwritten Tamil data. To the knowledge of the authors, this is the first ever attempt on recognition of open vocabulary, online handwritten paragraphs in any Indian language.

Higher education is rapidly trending toward the implementation of online (OL) courses and a blended facilitation style that incorporates both OL and face-to-face (FTF) classes. Though previous studies have explored the benefits and pitfalls of OL and blended learning formats from institutional, teacher, and student perspectives, scant research has examined learning outcomes for OL and FTF courses sharing identical content. This study used an explanatory mixed methods design—including pre- and post-test assessments, a questionnaire, and interviews—to explore similarities and differences in participant and teacher perceptions and outcomes (gain scores and final grades) of OL versus traditional FTF Communications courses, and to examine effects of students’ age and gender on learning preference and performance. Data collection occurred over a 4-month period and involved 183 student and 2 professor participants. The study used an SPSS program for data analysis and created a Microsoft Excel document to record themes derived from the questionnaire and interviews. Quantitative findings suggest there are no significant differences in gain scores, final grades, or other learning outcomes when comparing OL and FTF versions of identical Communications courses; however, qualitative findings indicate differences between facilitation styles based on student and professor perception. The study sheds light on student and faculty perceptions of facilitation styles and suggests areas for potential improvements in FTF- and OL-facilitated courses. The study ultimately recommends that students and faculty should have options when it comes to preferred delivery of course material.
