Transfer of manualized CBT for social phobia into clinical practice (SOPHO-PRAX) : a study protocol for a cluster-randomized controlled trial
Background: Cognitive-behavioral therapy (CBT) is generally known to be efficacious in the treatment of social phobia when applied in RCT's, namely when the treatment manual is based on the Clark-Wells approach. However, little is known about the efficacy of manualized treatments in routine clinical practice (Phase IV of psychotherapy research). The present study (SOPHO-PRAX) is a continuation of a large multi-centre randomized clinical trial (SOPHO-NET) and analyses the extent to which additional training practitioners in manualized procedures enhances treatment effect.
Methods: N = 36 private practitioners will be included in three treatment centres and randomly designated to either training in manualized CBT or no specific training. The treatment effects of the therapies conducted by both groups of therapists will be compared. A total of 162 patients (N = 116 completers; N = 58 per condition) will be enrolled. Liebowitz Social Anxiety Scale (LSAS) will serve as primary outcome measure. Remission from social phobia is defined as LSAS total [less than or equal to] 30 points. Data will be collected at treatment begin, after 8, 15, and 25 sessions (50 mins. each), at treatment completion, as well at 6 and 12 months post-treatment.
Discussion: The present CBT trial combines elements of randomized-controlled trials and naturalistic studies in an innovative way. It will directly inform about the incremental effects of procedures established in a controlled trial into clinical practice. Study results are relevant to health care decisions and policy. They may serve to improve quality of treatment, and shorten the timeframe between the development and widespread dissemination of effective methods, thereby reducing health cost expenditures. The results of this study will not only inform about the degree to which the new methods lead to an improvement of treatment course and outcome, but also about whether the effects of routine psychotherapeutic treatment are comparable to those of the controlled, strictly manualized treatments of the SOPHO-NET study. Trial Registration: ClinicalTrials.gov identifier: NCT01388231. This study was funded by the German Federal Ministry of Education and Research (SOPHO-NET: BMBF 01GV0607; SOPHO-PRAX: BMBF 01GV1001)
How would tourists use Green Spaces? Case Studies in Lisbon
EntretextosThis report provides in a relative condensed format the results of small-scale study undertaken in Lisbon during the
Meeting of the CyberParks Project (www.cost.eu/COST_Actions/tud/Actions/TU1306). CyberParks is a COST Action
coordinated by the Universidade LusĂłfona at the CeiED - Interdisciplinary Research Centre for Education and
Development. The Project aims at creating a research platform on the relationship between Information and
Communication Technologies (ICT) and the production of public open spaces, and their relevance to sustainable urban
development. The impacts of this relationship are being explored from social, ecological, urban design and technological
perspectives.
Based on the supposition that the participants of the Meeting are tourists visiting Lisbon, a survey was carried out on
the topic how people actually use and how they would use public spaces. This survey is also the first approach to the
case study areas chosen in Lisbon: Parque Quinta das Conchas and Jardim da Estrela. Both green spaces will be subject
of further studies in the forthcoming years.
This study employed (1) a questionnaire for measuring the userâs experience and preferences, and (2) two different
tracking devices that utilise GNSS (Global Navigation Satellite Systems), in our case the GPS for satellite positioning
technologies. It also presents the results of a study on the relevance of wi-fi in Lisbonâs public spaces. Even considering
that the surveys in Lisbonâs green spaces are a first exercise within the work programme of CyberParks they show
important outcomes. On the one hand, regarding the technologies used and their potential for research and on the
other hand the findings about Lisbonâs green spaces. It should be noted that the conducted surveys and the gathered
data are statistically not representative, but can be characterised as an empirical case and as a showcase, as how
tourists tend to use a green space. The results shows that surveys benefit from multiple research methods and from
combining insights.Este relatĂłrio apresenta, em formato condensado, os resultados de um estudo de pequena escala realizado em Lisboa
durante o Seminårio do Projeto CyberParks. CyberParks é uma Ação COST coordenada pela Universidade Lusófona/CeiED
- Centro de Estudos Interdisciplinares em Educação e Desenvolvimento. O projeto visa a criação de uma plataforma de
debate sobre a relação entre as Tecnologias de Informação e Comunicação (TIC) e a produção de espaços pĂșblicos, e
da sua relevùncia para o desenvolvimento urbano sustentåvel. Os impactos dessa relação estão a ser explorados a partir
de perspetivas sociais, ecolĂłgicas, tecnolĂłgicas e de desenho urbano.
Na sua etapa exploratória, este estudo assenta na suposição de que os participantes do Seminårio são turistas de visita
a Lisboa. A partir dos dados recolhidos pelos investigadores envolvidos na ação COST, foi realizada uma anålise à forma
como diferentes indivĂduos usam, e como poderĂŁo usar, diferentes espaços pĂșblicos verdes. Este estudo apresenta,
portanto, a primeira abordagem Ă s ĂĄreas de estudos selecionadas em Lisboa. SĂŁo elas o Parque Quinta das Conchas e
o Jardim da Estrela. Ambos os espaços verdes serão objeto de novos estudos nos próximos anos. Neste primeiro estudo
exploratĂłrio foram empregues: (1) um questionĂĄrio, para aferir a experiĂȘncia de um potencial utilizador e as suas
preferĂȘncias, e (2) dois dispositivos diferentes de rastreamento que utilizam tecnologia GNSS (Sistemas de Navegação
Global por Satélite) e, no nosso caso, o GPS para as tecnologias de posicionamento por satélite. Ele também apresenta
os resultados de um estudo realizado sobre a relevĂąncia do wi-fi em espaços pĂșblicos na cidade de Lisboa.
Mesmo considerando que os estudos realizados nos espaços verdes representam um primeiro exercĂcio no Ăąmbito do
programa de trabalho do CyberParks em Lisboa, sĂŁo aqui revelados resultados importantes. Por um lado, o recurso Ă s
tecnologias utilizadas e seu potencial para a investigação e, por outro lado, os resultados sobre a vivĂȘncia dos espaços
verdes. Deve-se notar que os dados recolhidos nĂŁo sĂŁo estatisticamente representativos, mas evidenciam um caso
empĂrico de como turistas tendem a usar um espaço verde urbano. A combinação do questionĂĄrio com novos mĂ©todos
digitais resultou num grande ganho de conhecimento, recobrindo as ĂĄreas de estudo sob a perspetiva de um turista,
para além de maiores informaçÔes sobre as potencialidades e limites da tecnologia digital como ferramenta de
investigação. Os resultados mostram que a investigação no campo social pode se beneficiar da combinação de vårios
métodos e técnicas

Knowledge Communities in Online Education and (Visual) Knowledge Management: 19. Workshop GeNeMeâ16 as part of IFKAD 2016: Proceedings of 19th Conference GeNeMe
Communities in New Media started in 1998 as a workshop series at TU Dresden, and since then has annually dealt with online communities at the interface between several disciplines such as education and economics, computer science, social and communication sciences, and more. (See Köhler, Kahnwald & Schoop, 2015). The workshop is traditionally a forum for interdisciplinary dialogue between science and business and serves to share experiences and knowledge among participants from different disciplines, organisations, and institutions.
In addition to the core themes of knowledge management and communities (in the chapters of the same name), the main focus of the conference is also on the support of knowledge and learning processes in the field of (media-assisted) higher education. This is complemented by an informational perspective when it comes to more functional and methodological approaches - use cases, workflows, and automation in knowledge management. In addition, systems and approaches for feedback, exchange, and ideas are presented. With the focus of knowledge media design and visual research as well as creative processes, this time there is also a highlight on visual aspects of knowledge management and mediation.
For IFKAD 2016, three GeNeMe tracks were accepted which focus on the interface of knowledge communities and knowledge management as well as knowledge media design in science, business, or education. In this conference volume you will find detailed information about these three tracks:
-- Knowledge Communities I: Knowledge Management
-- Knowledge Communities II: Online Education

Adress- und Autorenverzeichnis 251Gemeinschaften in Neuen Medien hat 1998 als Workshop-Reihe an der TU Dresden begonnen und seither jĂ€hrlich das Thema Online-Communities an der Schnittstelle mehrerer Disziplinen wie Informatik, Bildungs- und Wirtschaftswissenschaften, Informatik sowie Sozial-und Kommunikationswissenschaft u.a.m. thematisiert (vgl. Köhler, Kahnwald & Schoop, 2015). Der Workshop ist traditionell ein Forum fĂŒr den interdisziplinĂ€ren Dialog zwischen Wissenschaft und Wirtschaft und dient dazu, Erfahrungen und Wissen unter den Teilnehmern aus verschiedenen Disziplinen, Organisationen und Institutionen zu teilen.
Die inhaltlichen Schwerpunkte der Konferenz widmen sich neben den Kernthemen Wissensmanagement und Communities (in den gleichnamigen Kapiteln) auch der UnterstĂŒtzung von Wissens- und Lernprozessen im Bereich der (mediengestĂŒtzten) Hochschullehre. ErgĂ€nzt wird diese eher organisationswissenschaftliche durch eine informatorische Perspektive, wenn es um stĂ€rker funktionale bzw. auch methodische AnsĂ€tze geht â Use Cases, Workflows und Automatisierung im Wissensmanagement. DarĂŒber hinaus werden Systeme und AnsĂ€tze fĂŒr Feedback, Austausch und Ideenfindung vorgestellt. Mit den Schwerpunkten der Wissensmediengestaltung und visuellen Forschungs- sowie Kreativprozessen wird diesmal auch ein Schlaglicht auf visuelle Aspekte von Wissensmanagement und -vermittlung geworfen.
FĂŒr die IFKAD 2016 wurden drei GeNeMe-Tracks angenommen, die sich auf das Interface von Wissensgemeinschaften und Wissensmanagement sowie die Wissensmediengestaltung in Wissenschaft, Wirtschaft oder Bildung konzentrieren. Im vorliegenden Tagungsband finden Sie detaillierte Informationen zu diesen drei Tracks:

Cost implications of various Euro 4 and 5 after treatment solutions for heavy duty diesel vehicles
This study is firstly a short review of the types of exhaust systems predicted for Euro 4 (2005) and Euro 5 (2008), particularly focussed on the effects of combined NOx (nitrogen oxides) and PM (particulate matter) aftertreatment systems. Secondly, it explores in detail the implications of using a liquid secondary water-based fuel of urea on board heavy duty diesel vehicles in Europe as a basis for NOx reduction via selective catalytic reduction (SCR). Some of the main points that become apparent when using integrated SCR systems are: the potential costs of increased urea production in Europe (including possible fuel taxation), refuelling issues, secondary fuel cost, logistics of urea supply, and cost of implementation of the urea fuel delivery method. From the original equipment manufacturers view, the hardware cost will be increased substantially when compared to current silencer systems. From the vehicle ownerâs point of view, the possibility of large running cost increases is not desired, and the system solution cost and its benefits must ultimately be acceptable. This paper will attempt to put the life-time costs of various systems within perspective in order to assess the feasibility of implementing selective catalytic reduction systems (SCR) Europe wide for the near future
IT Supported Construction Project Management Methodology Based on Process and Product Model and Quality Management
Computer Integrated Construction Project Management (CPM) supported by product and process models can be seen as a future type of integration structure facilitating the solution of various management problems in the fragmented Construction Industry. The key to success is directly correlated with the comprehensive integration of currently isolated IT applications. However, despite that a number of initiatives have been developed, no fully generic models have yet to be formally standardized. This topic has been the subject of intensive research during the last decades. In this thesis a Computer Integrated CPM approach, which is supported by IFC (Industry Foundation Classes) and ISO9001:2000 Quality Management System, is proposed. The main aim is to provide integration of product, process and organizational information to help achieve the interoperability of the involved actors and tools in a concurrent environment. According to implied requirements which are represented in the âstate of the artâ section, the fundamental concepts are presented in two parts as: (1) realization of CPM in an IT concept and (2) formalization of IFC Views for software interoperability on the example of Bidding Preparation Phase. In order to realize a generic framework using a high-level process core model named Organizational Management Process (OMP) model, different aspects have been brought together into a consistent life cycle structure. These are: (1) a set of layered processes based on ISO procedural definitions, (2) software integration requirements based on Construction Management Phases, (3) application methods of the Procurement System and (4) Organizational data. This provides for synchronizing technical products, processes, documents, and actors in their inter-relationship. The framework is hierarchically structured in three layers Phases â Processes - Product data. The developed IT Management Processes (ITMP) which are used as a baseline for the IFC Views implementation are derived from the OMP. Moreover, in order to support completeness, a mapping structure between processes and scenarios based on the Procurement Systems was constituted. The representation of OMP and ITMP is provided by using the ARIS eEPC (extended event-driven process chain) modeling method. On the basis of a generalized representation of product data, a system-wide integration model for heterogeneous client applications which supports different CPM areas can be achieved. IFC Product Data Model integrates different domains thereby enabling coordination of bidding preparations. However, there is a need to realize individual model subsets. i.e. views of the product model. In this context, adaptable views were developed based on ITMP. The defined resourcesâ relevancies to IFC Objects are examined by realizing central information elements. These provide a mapping structure between process resources and IFC Classes. On that basis integration of process and product models can be accomplished. In order to realize IFC Views, IFC Concepts and IFC Instance Diagrams were developed based on IFC View Definition Format. The grouping of IFC Concepts enables the implementation of the adaptable IFC Views that are required for standardized system integration. This is achieved with the help of formal specification using the Generalized Subset Definition Schema. The validation has been made based on an alphanumerical comparison. The selected 3D full-model and the developed IFC View for Product Catalog models are compared in this context. There are two consequences observed. In the first case, which also addresses Unit Price Procurement systems, the desired results were obtained by filtering the required data. However, when the results were compared for Design & Build and Lump-sum Procurement Systems (contracts), an extension need was observed in the IFC Model. The solution is provided via formalization of cost data and material analysis information by an extension of IFC Concept namely âIfcConstructionResourceâ with new classes and with new relations. Thereby a common information model based on the data schema of the IFC standard is constituted.Das von Produkt- und Prozessmodellen unterstĂŒtzte computerintegrierte Bauprojektmanagement (CPM) kann als der zukĂŒnftige Typ der Integrationsstruktur angesehen werden, der die Lösung verschiedener Baumanagementprobleme in der fragmentierten Bauindustrie erleichtern kann. Der SchlĂŒssel zum Erfolg steht in direkter Beziehung zu einer umfassenden Integration derzeit getrennter IT-Anwendungen. Trotz zahlreich entwickelter AnsĂ€tze, die zur VerfĂŒgung gestellt wurden, sind bisher noch keine vollstĂ€ndig generischen Modelle formell standardisiert worden, obwohl dies in den letzten Jahrzehnten ein Thema intensiver Forschung war. In dieser Promotionsschrift wird eine computerintegrierte CPM-Methode, die auf Basis der IFC (Industry Foundation Classes) und dem QualitĂ€tsmanagement ISO 9001:2000 aufbaut, vorgeschlagen. Das Hauptziel besteht in der Schaffung der Integration von Produkt-, Prozess- und Organisationsinformationen, um die InteroperabilitĂ€t der beteiligten Akteure und Tools in einer parallelen Umgebung erreichen zu können. Entsprechend den Anforderungen, die im Abschnitt âStand der Technikâ aufgefĂŒhrt sind, werden die vorgeschlagenen, grundlegenden Konzepte in zwei Bereiche aufgeteilt: (1) Umsetzung der CPM-Prozesse in ein IT-Konzept und (2) Formalisierung der IFC-Sichten fĂŒr die InteroperabilitĂ€t von Software, beispielhaft ausgefĂŒhrt fĂŒr die der Ausschreibungsphase. Um einen generischen Rahmen unter Verwendung eines hochrangigen Prozesskernmodells, das als organisatorischer Managementprozess (OMP) bezeichnet wird, zu realisieren, werden zuerst die verschiedenen Aspekte in einer konsistenten Lebenszyklenstruktur zusammengefĂŒgt. Diese sind: (1) eine Menge hierarchisch geschichteter Prozesse, erstellt auf der Grundlage der Verfahrensdefinitionen von ISO 9001, (2) die Softwareintegrationsanforderungen auf der Grundlage der Baumanagementphasen, (3) die Anwendungsmethoden des Beschaffungssystems und (4) die Organisationsdaten. Dadurch wird die Synchronisation der in Wechselbeziehung stehenden technischen Produkte, Prozesse, Dokumente und Akteure geschaffen. Das gesamte System ist hierarchisch in die drei Ebenen Phasen â Prozesse â Produktdaten strukturiert. Die entwickelten IT-Managementprozesse (ITMP), die als Grundlage fĂŒr die IFC-Implementierungssichten dienen, werden aus dem OMP hergeleitet. Der VollstĂ€ndigkeit halber, wird eine Abbildungsstruktur zwischen den Prozessen und den Szenarien, die die Beschaffungssysteme beschreiben, entwickelt. Die Darstellung der OMP und ITMP erfolgt unter Verwendung der erweiterten ereignisgesteuerten Prozessketten (eEPK) nach der ARIS-Modelliermethode. Auf der Grundlage einer verallgemeinerten Darstellung der Prozessdaten kann das systemweite Integrationsmodell fĂŒr heterogene Client-Anwendungen, das verschiedene CPM-Bereiche unterstĂŒtzt, erreicht werden. Das IFC-Produktdatenmodell integriert verschiedene DomĂ€nen und ermöglicht somit die Koordinierung der hier beispielhaft gewĂ€hlten Ausschreibungsbearbeitungen. Hierzu ist es notwendig, Teilmodelle, d. h. Sichten des Produktmodells zu erzeugen. Entsprechend wurden anpassbare Sichten auf der Grundlage von ITMP entwickelt. Die Bedeutung der in diesem Zusammenhang identifizierten Informationsprozessressourcen in Bezug auf die IFC-Objekte wurde durch die EinfĂŒhrung zentraler Informationselemente, sog. IFC Concepts, untersucht. Diese stellen eine Abbildungsstruktur zwischen den Prozessressourcen und IFC-Klassen zur VerfĂŒgung. Auf dieser Grundlage konnte die Integration von Prozess- und Produktmodellen erreicht werden. Um die IFC-Sichten zu realisieren, wurden auf der Grundlage des IFC-Sichtendefinitionsformats IFC-Konzepte und IFC-Instanzendiagramme entwickelt. Die Gruppierung in IFC-Konzepten ermöglichte die Implementierung von anpassbaren IFC-Sichten, die fĂŒr die standardisierte Systemintegration erforderlich sind. Diese wird mit Hilfe einer formellen Spezifikation unter Verwendung der verallgemeinerten Subset-Definitionsschema-Methode (GMSD) erreicht. Die Validierung erfolgte auf der Grundlage eines alphanumerischen Vergleichs, in dem ein ausgewĂ€hltes 3D-Produktmodell und die daraus entwickelte IFC-Sicht fĂŒr das Produktkatalogmodell verglichen wurden. Es ergaben sich zwei Schlussfolgerungen. Im ersten Fall, der auch das Einheitspreisbeschaffungssystem betrifft, konnten die gewĂŒnschten Ergebnisse direkt durch Filterung der erforderlichen Daten erhalten werden. Beim Vergleich der Ergebnisse sowohl fĂŒr Pauschal-, als auch fĂŒr Entwurfs- und Baubeschaffungssysteme (VertrĂ€ge) wurde jedoch festgestellt, dass fĂŒr das IFC-Modell ein Erweiterungsbedarf besteht. Eine Lösung wurde ĂŒber die Formalisierung der Kostendaten und Materialanalyseinformationen durch Erweiterung des IFC-Konzepts IfcBauRessource mit neuen Klassen und mit neuen Beziehungen erreicht. Somit erhĂ€lt man ein allgemeines Informationsmodell auf der Grundlage des Datenschemas des IFC-Standards
Green spaces â a key resources for urban sustainability. The GreenKeys approach for developing green spaces
Following the principles of sustainable development all urban development programmes set down ideas and ideals to develop our cities in a more long-lasting way, especially concerning the environment and the social dimension. These programmes result from a process of searching for and then offering a better quality of life. Green space assumes a key role for improving the quality of urban life - not only because of their ecological and environmental functions but also of their relevance for public health, societal well-being and economic benefits they can provide. Urban green spaces are therefore key resources for sustainable cities. Starting with this principle the GreenKeys Project developed a methodology to approach better green space qualities. Then if we are unable to demonstrate effectively the value that green spaces deliver we risk green spaces remaining on the periphery of public policy priorities and unable to attract more resources. The article presents and discusses the results and outcomes of the GreenKeys Project. Especially the GreenKeys proposal for supporting the formulation of an Urban Green Space Strategy is widely discussed
