Full textAbstract:
There has long been a concern about the research-practice gap within Library and Information Science (LIS). Several authors have highlighted the disconnection between the world of professional practice, interested in service and information system development, and the world of the academy, focused on the development of theory and the progress of the discipline. A virtual organization, such as a collaboratory, might support collaboration between LIS professionals and academics in research, potentially transforming the way research between these two groups is undertaken. The purpose of this study was to examine how sociotechnical aspects of work organization influence the initiation, development, and conclusion of collaboration between LIS academics and professionals in distributed research projects. The study examined the development of three collaborative projects from the start to completion in two countries, Italy and another European country. The data analysis aimed at deriving implications for the further development of theory on remote scientific collaboration, and for the design of a sustainable collaboratory to support small-scale, distributed research projects between LIS academics and professionals. The research design, data collection, and data analysis were informed by Actor- Network-Theory (ANT), in particular by Callon’s model of translation of interests. Qualitative interviews and analysis of literary inscriptions formed the key sources of data for the three case studies. The analysis of how and why collaborations between LIS academics and professionals initiated and developed revealed that the initial motivation to pursue collaboration has to do with the lack of economic and organizational resources on either or both sides, and with a genuine interest in a topic by both academics and professionals. The case studies in this study were decentralized and bottom-up projects in which LIS academics and professionals pursued collaboration because they had a genuine interest in a given topic and not because they were mandated by their employers, or they hoped to be acknowledged and promoted by them on the basis of their participation in the project. Market conditions and/or institutional pressures did not exert much influence on the start and development of these collaborations, although one project was influenced by political considerations and funding conditions in healthcare. The patterns emerged from the findings of the three cases underpin the development of a sociotechnical framework aimed at providing a better understanding of remote collaboration between academics and professionals not only in LIS but also in other fields affected by the research-practice gap.<br><p>Akademisk avhandling som med tillstånd av samhällsvetenskapliga fakulteten vid Göteborgs universitet för vinnande av doktorsexamen framläggs till offentlig granskning kl. 13.15 torsdagen den 29 april 2010, i hörsal C203, Högskolan i Borås, Allégatan 1, Borås.</p>

Full textAbstract:
Network Coding is a new possibility to transmit data through a network. By combining different packets instead of simply forwarding, network coding offers the opportunity to reach the Min-Cut/Max-Flow capacity in multicast data transmissions. However, the basic schemes are vulnerable to so-called pollution attacks, where an attacker can jam large parts of the transmission by infiltrating only one bogus message. In the literature we found several approaches which aim at handling this kind of attack with different amounts of overhead. Though, the cost for a specific secure network coding scheme highly depends on the underlying network. The goal of this paper is on the one hand to describe which network parameters influence the efficiency of a certain scheme and on the other hand to provide concrete suggestions for selecting the most efficient secure network coding scheme considering a given network. We will illustrate that there does not exist “the best” secure network scheme concerning efficiency, but all selected schemes are more or less suited under certain network topologies.

Full textAbstract:
In the modern society, chronic diseases have become the leading causes of death. With early recognition and proper management, however, many of the complications from chronic diseases could be prevented or delayed. Taking such a proactive approach in managing a population often requires the use of team-based approaches and delegation of certain clinical and nonclinical tasks to nonphysician team members. This three-study dissertation used a combination of methods to explore contextual factors that influence primary care teamwork and physician-pharmacist collaboration. The first study quantitatively examined baseline barriers and facilitators of physician-pharmacist collaboration in clinics participating in the Collaboration Among Pharmacists and Physicians To Improve Outcomes Now (CAPTION) Trial. Pharmacist expertise and clinic staff support were found to be the most important facilitators for physicians, while insurance reimbursement and task design factors were important for pharmacists. The second study characterized clinic personnel experience participating in the CAPTION trial and explored determinants of disease state control. Higher proportions of indigent and minority populations and higher baseline pharmacy structure scores were found to be associated with lower blood pressure control. The third study qualitatively examined organizational influences on primary care team effectiveness and the roles of pharmacists in a separate sample of primary care clinics. A lack of organizational rewards for teamwork in primary care was identified and pharmacists were integrated into clinic workflow in various degrees. These findings will be informative for practice managers and health care professionals seeking to redesign their practice to meet increasing needs of patients with chronic diseases.

Full textAbstract:
As public agencies have implemented programs to respond to natural disasters, alleviate poverty, provide food security, and address other wicked problems, the organizational structuring of public sector program management has changed in response. The federal agencies responsible for U.S. foreign policy, including the United States Agency for International Development (USAID), have embraced multi-organizational, cross-sector network collaboration as part of their core missions. The strategic transition of USAID to an increased use of network models for program implementation raises questions concerning the ability of the agency, through its partners, to foster organizational learning in this network setting. Ensuring the ability to utilize knowledge and ways of knowing generated through program activity is a critical factor to sustaining the long-term capacity of government agencies and their partners to pursue solutions for these complex global problems. The research reported in this dissertation focuses on network administrative organizations (NAOs) delegated official responsibility for the management of government-funded multi-institutional programs, to understand how organizational learning for innovation takes place in an NAO-led network. This research explored the USAID Feed the Future Innovation Labs for Collaborative Research program focusing on two comparable case studies representative of NAO-led goal-directed networks, the Integrated Pest Management and Horticulture Innovation Labs. The Crossan et al. (1999) 4I framework on organizational learning served as the primary theoretical foundation for addressing how NAOs enable, manage, and leverage organizational learning associated with the boundary work of their program team representatives to innovate as networks. In the two cases studied, the findings indicated that learning practices flowed as anticipated within and across the program network for program and administrative related knowledge, but flowed in a number of different directions for knowledge related to addressing novel problems. Additionally, the NAOs' ability to institutionalize knowledge generated through the work of program teams and individual members followed unpredictable patterns and was influenced by the presence of knowledge and learning boundaries within the network. The research contribution includes a theorized two-part role for NAOs associated with managing situational learning on behalf of the network and a proposed expansion of the 4I framework that incorporates a network level of learning, organizational boundaries, and two new processes introduced as a result of the findings. Finally, the research concludes with a proposed a preliminary framework beneficial to NAO practitioners tasked with managing organizational learning in similar goal-directed network environments.<br>PHD

Using a Systems Theory approach allows a person to analyze the intertwined elements of the drug development system and the potential influences of the environment. Thomas Hughes's Large Technological Systems (LTS) Theory is one that could be used for this purpose; however, it falls short in its ability to address the complexity of current day regulatory environments. This dissertation provides a critical analysis of Hughes's LTS Theory and his phases of evolution as they apply to the United States (U.S.) system for biologic drug research, development and labeling. It identifies and explains potential flaws with Hughes's LTS Theory and provides suggested improvements. As an alternative approach, this dissertation explores the concept of "techno-regulatory system" where government regulators play an integral part in system innovations and explains why such systems do not always follow Hughes's model. Finally, this dissertation proposes a hybrid version of Hughes's systems approach and uses it to explain the changes that occurred in the drug approval system in response to the push for, opposition, and inclusion of, pediatric research in drug development during the period 1950-2003.<br>Ph.

Preventing the success of active attacks is of essential importance for network coding since even the infiltration of one single corrupted data packet can jam large parts of the network. The existing approaches for network coding schemes preventing such pollution attacks can be divided into two categories: utilize cryptographic approaches or utilize redundancy similar to error correction coding. Within this paper, we compared both paradigms concerning efficiency of data transmission under various circumstances. Particularly, we considered an attacker of a certain strength as well as the influence of the generation size. The results are helpful for selecting a suitable approach for network coding taking into account both security against pollution attacks and efficiency.

Thesis (PhD)--Macquarie University, Division of Information and Communication Sciences, Computing Department, 2008.<br>Bibliography: p. 503-514.<br>This study investigated learning design in a web-conferencing environment based on three semesters of lessons conducted as part of an introductory programming subject. As well as characterizing the nature of discourse and interaction, the study focused on how the design of the interface, activity and task type affected collaboration and learning. Engeström's (1987) Activity Theory based upon a socio-constructivist view of learning was used to frame the analysis. --Interface designs incorporated theory relating to graphical user interface design, multimedia learning, and findings from the cognitive sciences. Activity designs were differentiated based on the degree of student ownership, from teacher-centred (transmissive) approaches, to teacher-led (guided interaction) approaches, to student-centred (collaborative group-work) designs. Types of tasks were considered on the basis of their level of knowledge (declarative, procedural and conceptual), their character (authenticity, situatedness) and their domain specific nature (in the field of computer science education). The effects of the different interface, activity and task designs on collaboration and mental model formation were explored. --A mixed method approach to analysis was adopted, incorporating a design-based research study and a multimodal discourse analysis. The design-based research allowed a broader, more interpretivistic and process focused analysis to be conducted, based on the strategic redesigns that occurred between iterations of the subject. The multimodal discourse analysis enabled more detailed, objective and outcomes based measurements of the subject of discourse, the nature of interactions and the types of modalities used to mediate learning. Triangulating data from the design-based research study and the multimodal discourse analysis provided a more complete description of phenomena and promoted greater reliability. --Results include the way in which different modalities afforded different possibilities for representing, and how combinations of those modalities could be effectively integrated by applying multimedia learning principles. Student-centred learning designs increased student involvement, allowing them to take greater ownership over the content and to more fully share their mental models. Authentic, meaningful problem solving tasks promoted greater student engagement. The capacity to dynamically redesign the interface based on the collaborative and cognitive requirements of the learning episode supported more effective implementation of conversational (Laurillard, 2002) approaches to learning. --More effective interaction and collaboration resulted from prescribing patterns of engagement, managing activity and technology so that student discourse could focus on content, and providing guidance regarding semiotic representational forms so that students could concentrate on applying those representations rather than inventing them. Teacher and student virtual classroom competencies critically influenced collaboration and learning. --Based on the findings in this study, a framework of nine pedagogical patterns for teaching and learning in web-conferencing environments is proposed. The framework provides an integrated approach to learning design that relates the interface design with the activity design and the level of knowledge (task type).<br>Mode of access: World Wide Web.<br>vii, 514 p. ill.

We consider the problem of secure communications in a Gaussian two-way relay network where two nodes exchange confidential messages only via an untrusted relay. The relay is assumed to be honest but curious, i.e., an eavesdropper that conforms to the system rules and applies the intended relaying scheme. We analyze the achievable secrecy rates by applying network coding on the physical layer or the network layer and compare the results in terms of complexity, overhead, and efficiency. Further, we discuss the advantages and disadvantages of the respective approaches.

Full textAbstract:
Cette thèse propose d’utiliser un cadre empirique pour évaluer la politique européenne en matière de recherche et développement. Le programme-cadre (PCRD), qui incarne l’action européenne dans ce domaine, est au cœur de l’analyse. L’objectif est de déterminer si des preuves d’efficacité peuvent être trouvées en confrontant les effets observés de du PCRD avec ses objectifs cibles et son fonctionnement. Dans ce but, trois analyses sont présentées. Le premier chapitre analytique porte sur le réseau de collaboration formé par les projets de recherche soutenus. L’utilisation des méthodes d’analyse des réseaux sociaux nous donne un aperçu de la structure de l’Espace Européen de la Recherche. Tout en identifiant l’épine dorsale potentielle du réseau, des tests de résilience et d’efficacité sont effectués. Le deuxième chapitre a pour but de décrire comment la structure des projets collaboratifs influence la création de connaissances. Une attention toute particulière est accordée à l’identification des interactions qui peuvent fonctionner à l’intérieur et à l’extérieur des partenariats financés; ainsi, les caractéristiques des partenaires et les effets de réseau sont au centre de l’enquête. Cette méthode fournit un regard complémentaire sur l’efficacité du programme, en particulier au niveau des projets. Le dernier chapitre adopte une approche micro-fondée sur l’entreprise et s’interroge sur l’impact des PCRD. La question est la suivante: le PCRD stimule-t-il les performances des lauréats ou constitue-t-il un goulot d’étranglement pour l’innovation et la croissance ? Pour y répondre, une analyse de causalité est nécessaire, nous l’appliquons donc à trois performances économiques : la solvabilité, la productivité et la rentabilité des entreprises soutenues. En fin de compte, une comparaison est faite entre les effets du PCRD et ceux de EUREKA afin d’établir laquelle des deux structures est la plus favorable à la croissance des entreprises<br>This thesis proposes to assess the European policy in Research and Development through an empirical scope. The Framework Programme (EUFP), which embodies the Euro- pean action in the field, is at the core of the analysis. The aim is to determine whether evidence of effectiveness can be found when confronting observed effects of EUFP with both its targeted- objectives and functionning. In that purpose, three analyses are laid out. The first analytical chapter focuses on the collaborative network formed by supported re- search projects. The use of social network analysis methods gives us a view on the structure of the European Research Area. While identifying the potential backbone of the network, tests of Resilience and effectiveness are runned. The aims of the second chapter is to describe the role of research collaborations structure on knowledge creation. Particular attention is placed on identifying interactions that may operate inside and outside supported partnerships; thus, partners characteristics and network effects are at the centre of the investigation. This method provides complementary evidence on program effectiveness especially at projects level. The last chapter adopts a firm-based approach and questions the impact of such program. Does EUFP stimulate laureates performances or does it act as a bottleneck for innovation and growth? Answering this, asks for causal methodology that we implement with regard on three economic performances: solvency, productivity and profitability of supported firms. Ultimately, a compar- ison is made with the EUREKA program effects to establish which one from EUFP top-down structure and EUREKA bottom-up one is more favorable for economic growth

We can all use assessment and appraisal to help us improve our performance in any area of life. Healthcare researchers are no exception. For healthcare researchers a system is required to measure research performance according to an accepted global benchmark. While there are existing systems that have been created to measure research performance in general, and healthcare research performance has been appraised with several bibliometric indicators, there is a lack of evidence to prove their validity and a deficiency of indicators that embrace social behaviours such as collaboration. In this thesis we endeavoured to enhance knowledge on healthcare research performance assessment, which has the potential to be integrated into systems that specifically appraise healthcare research performance. Ultimately, these systems may promote a performance-based culture that better reflects the quality and impact of healthcare research.

Full textAbstract:
There is substantial competition among academic institutions. They compete for students, researchers, reputation, and funding. For success, they need not only to excel in teaching, but also their research profile is considered an important factor. Institutions accordingly take actions to improve their research profiles. They encourage researchers to publish frequently and regularly (publish or perish) on the assumption that this generates both more and better research. Collaboration has also been encouraged by institutions and even required by some funding calls. This thesis examines the empirical evidence on the interrelations among institutional research productivity, impact and collaborativity. It studies article publication data across ACM and Web of Science covering five disciplines { Computer Science, Pharmacology, Materials Science, Psychology and Law. Institutions that publish less seek to publish collaboratively with other institutions. Collaboration boosts productivity for all the disciplines investigated excepted Law; however, the amount of productivity increase resulting from the institutions' attempt to collaborate more is small. The world's most productive institutions publish at least 50% of their papers on their own. Institutions doing more collaborative work are not found to correlate strongly with their impact either. The correlation between collaborativity and individual paper impact or institutional impact is small once productivity has been partialled out. In Computer Science, Pharmacology and Materials Science, no correlation is found. The decisive factor appears to be productivity. Partialling out productivity results in the largest reductions in the remaining correlations. It may be that only better equipped and well-funded institutions can publish without having to rely on external collaborators. These institutions have been publishing most of their output non-collaboratively, and are also of high quality and highly reputable, which may have equipped and funded them in the first place.

Purpose: The main purpose of this study/thesis is to, through an interview with researchers in medical field in Jönköping, provide an empirical analysis of the link or relationship between medical researcher and patient through social networking sites specifically for collaboration in order to improve relationships, dissemination of information and knowledge sharing. Background: The importance of social networking websites as a means of interaction between groups of individuals cannot be underestimated. Their impact on daily life activities and activities cannot be underestimated. Because millions of individuals are making use of Social Network Sites (SNSs) to build or reinforce relationships, connect, disseminate and share information as well as sharing of knowledge whether personal or non-personal experiences with people they already know offline or new people online. Therefore, the authors are interested basically in how social networking web sites are being utilized in terms of collaborations, information and knowledge sharing and particularly in what benefits and challenge are connected to improving inter-groups collaboration in research study between researchers and ordinary citizens. Method: A review of literature gives us insight about the subject terms, critical and sensitive issues in regards to collaboration through social networking sites designed for research purpose. We apply in general networking theories such as social capital and two of its components couple with Putman´s theory of bonding and bridging social capital as a theoretical framework to synthesize the concept of ties (strong or weak) . Our analysis based on the empirical data gathered through surveys, interviews and observation provide us with interesting preliminary results and with blueprints to guide the analysis of the thesis. Conclusion: Social networking platforms are valuable and useful in our generation being part of daily life and activity to keep up with people within our networks. However, the authors discovered that the advantages of involving ordinary citizens to participate in improving researcher-patient collaboration through dynamic social networking actually outweigh the disadvantages despite all odds and sensitive issues such as trust, privacy issues and sceptics of some researchers. In others words, some of the researchers were enthusiastic to collaborate in terms of disseminating useful information and sharing valuable knowledge with ordinary citizens. Overall, the study revealed positive result that despite weak ties relationships, the willingness to collaborate is far more than the obstacles perceived in the course of establishing such collaboration.

Full textAbstract:
Today large research projects require substantial involvement of researchers from different organizations, disciplines, or cultures working in groups or teams to accomplish a common goal of producing, sharing, and disseminating scientific knowledge. This study focuses on the international research team that was launched in response to pressing calls for internationalization. This study seeks to understand the social structure of the international research team and perceptions of team members on this structure by challenging social networks and social capital fields. By bridging social networks with social capital, the study examines social structures at the individual, subgroup, and team levels and adds complexity to different levels of analysis by stressing context through qualitative research methods. The results imply that hierarchical relations do not stand separately from the horizontal relations among team members in the international research team. Therefore, the construct of group social capital should be based on a multilevel model of combined moderate closure with horizontal bridging roles in international research teams.

Full textAbstract:
Professional burnout refers to the development of negative emotions, cynical thoughts, and physical and mental exhaustion as a response to stressors associated with one’s career. Within the teaching profession, professional burnout has been associated with an increase in teacher attrition. In an effort to promote a positive school environment where teachers feel supported and committed to the profession, many administrators have implemented structured collaborative opportunities within their buildings.
While personal relationships within the school network can provide a mitigating effect against professional burnout, the possibility exists that teacher leaders can be overcentralized and negatively impacted by the maintained relationships. By potentially forcing centralization on critical team members and emphasizing them as the “go-to” person for collaboration, schools may be inadvertently putting their best at risk for burnout.
Using a mixed-methods design, the following study investigates the perceived benefits and constraints of centrality within the school network on reported burnout. The social networks at four elementary schools were analyzed to determine the level of connectivity for each certified staff member. Participants were asked to identify the colleagues with whom they collaborate. Using Social Network Analysis, the level of centrality (as measured by number of network connections both received and directed) was calculated for each participant based on number of network ties both received and directed. Centrality scores were included with previously identified variables associated with teacher burnout including level of perceived stress, perception of school environment, principal support, and other demographic data in a series of hypothesis tests to assess the relationship between network connectivity and reported burnout. A series of semi-structured interviews were conducted with a selection of participants to further explore the impact of network connections on participant burnout.
The results of this exploratory study found that not all collegial relationships are beneficial. A significant positive relationship between number of collaborative ties directed toward a teacher and their depersonalization score on the Maslach Burnout Inventory was identified, indicating that individuals who are frequently identified as a collaborator report higher burnout. The findings from this study produce a unique perspective on collaboration within the school network. As has been reported previously, level of connectivity within the school network as measured by the number of teachers one can identify as collaborators appears to mitigate (or not significantly increase) a teacher’s risk of professional burnout. However, being identified as a collaborator by a large number of teachers (in-degree) significantly increases one’s risk for depersonalization behaviors.

Cette thèse porte sur la création de connaissances scientifiques et technologiques,et son lien avec la géographie et le réseau social. En ce sens la thèse s’attacheà mieux identifier le rôle du réseau social dans la production de connaissance, et à éclairerle lien entre réseau social et géographie dans la formation des collaborations, en mettanten avant dans quelles conditions le réseau permet de s’affranchir de cette dernière. Acet égard, cette thèse apporte plusieurs contributions théoriques, méthodologiques et empiriques.L’essentiel de la thèse s’applique à assembler les mécanismes qui lient le réseausocial à la production de connaissances. La discussion théorique est ensuite appuyée parune analyse empirique dans deux contextes liés la création de connaissances. D’une partla thèse analyse la formation du réseau des collaborations scientifiques en Europe dansle domaine de la chimie, mettant en avant l’interaction réseau versus géographie dansla formation des collaborations. D’autre part, elle évalue le rôle du réseau d’inventeurdans la performance des zones d’emploi françaises en termes de production d’innovation,en se focalisant sur le type de structure de réseau qui favorise le plus l’innovation. Lesrésultats principaux sont que l’expansion du réseau social – mesuré par la connectivitédes inventeurs – a un effet bénéfique sur l’innovation. De plus, il est montré que le réseausocial permet en partie de s’affranchir de la barrière géographique pour collaborer. Cesrésultats apportent des éclairages sur le rôle du réseau dans l’organisation spatiale desactivités scientifiques et technologiques<br>This thesis pertains to understanding how social networks and geography affect thecreation of new knowledge. More precisely, this thesis will question how the social networkof collaboration can influence the production of knowledge, how do geography and thesocial network interact, and whether the social network can help to bypass geography. Answeringthese questions required to make some theoretical, methodological and empiricalcontributions. One part of the thesis gathers the mechanisms linking the social network toknowledge creation, while another focuses on the interplay of geography and the networkinto the collaboration process. Following this theoretical discussion, two empirical studiesare laid out. First, it assesses the formation of scientific collaborations in Europe in thefield of chemistry. This study focus on the competing role between the social network andgeography to shaping new collaborations. Then, the thesis comes to evaluate how thenetwork of inventors influence the innovation performance of French employment areas.In particular, a specific methodology is set up to address what kind of network structurefavours the most collaboration. The main results of this thesis are that an increase inthe connectedness of inventors is always beneficial to urban innovation performance. Wealso show that social network act as a substitute to geographic distance, so that socialnetwork allows to alleviate the burden of distance. These results shed light on the role ofthe network in shaping the spatial distribution of the scientific and technological activity

Full textAbstract:
Le but de ce travail de thèse réside dans la planification de la distribution urbaine des marchandises dans un système de transport collaboratif. Cette collaboration consiste à échanger les demandes de transport entre transporteurs afin d'améliorer l'efficacité de leurs opérations. Cela revient à minimiser la distance parcourue par les camions et à maximiser le profit collecté des clients, notamment en recourant à des variantes du problème de tournées de véhicules plus adaptées au contexte collaboratif. Le problème opérationnel sous-jacent est donc le problème de tournées de véhicules sélectives dans lequel le service de tous les clients n'est pas obligatoire par contre un "profit" est collecté lors du service d'un client. Dans cette thèse, nous traitons le problème de tournées de véhicules sélectives avec contraintes de temps et de capacité (Capacitated Team Orienteering Problem - CTOP). Nous proposons une métaheuristique qui alterne entre deux espaces de recherche. Des procédures de découpage optimal et de concaténation permettent de passer d'un espace à un autre. D'autre part, en considérant des demandes de collecte et de livraison, nous traitons deux variantes sélectives du problème de collecte et de livraison (Pickup and Delivery Problem - PDP) : le PDP avec fenêtres de temps et demandes obligatoires (PDPTWPR) et le PDPTWPR avec demandes groupées. La première variante consiste à choisir parmi les demandes de transport optionnelles quelles demandes à servir en plus des demandes obligatoires. Nous développons des métaheuristiques pour traiter les cas mono-objectif et multi-objectif du problème. Le PDPTWPR avec demandes groupées prend en considération les demandes de transport qui doivent être servies par un même transporteur. Finalement, nous considérons la variante sélective dans laquelle les marchandises sont distribuées d'un même dépôt vers les clients (Capacitated Profitable Tour Problem - CPTP). L'objectif est de maximiser la différence entre le coût et le profit. Pour résoudre ce problème, nous proposons un algorithme de résolution exacte basé sur la programmation linéaire en nombres entiers à laquelle nous ajoutons plusieurs inégalités valides spécifiques à ce problème. Des expérimentations ont été conduites sur plusieurs classes d'instances afin de montrer l'efficacité de nos approches<br>The goal of this thesis is to plan urban freight distribution in a collaborative logistic system. The collaboration consists in exchanging transportation requests between carriers to increase the efficiency of their operations. More precisely, when solving variants of the wellknown vehicle's routing problems in collaborative context, less kilometers can be driven and higher prices can be collected. The underlying operational problem is therefore the selective vehicle routing problem in which not all customers can be served, but a "profit" is gained for each served one. In this thesis, we firstly address the Capacitated Team Orienteering Problem (CTOP), a selective variant of the VRP in which capacity and travel time limitations are imposed to vehicles. We propose a variable space search metaheuristic that alternates between two different search spaces to solve CTOP. Then, we consider pickup and delivery requests to study two variants of the selective pickup and delivery problem: the PDP with Time Windows and Reserved requests (PDPTWPR) and the Clustered PDPTWPR. The first aims to choose suitable selective requests to be transported in addition to reserved ones. Metaheuristics are proposed to deal with the single-objective and the multi-objective sides of the problem. The second takes into consideration groups of requests that must be served by only one carrier. Finally, we consider the Capacitated Profitable Tour Problem (CPTP) in which goods need to be distributed from the depot to customers. We propose an exact method based on Integer Linear Programming to solve this problem. A set of cuts specific to CPTP is proposed in order to speed up the solution process. Experiments were conducted on a variety of instances of different sizes to demonstrate the effectiveness of our solution methods

Full textAbstract:
This dissertation studies the relationship between collaboration networks and scientific creativity. It finds significant knowledge spillover from new collaborations to repeated collaborations, and proposes a network approach to understand scientific creativity at the egocentric network level beyond the boundary of teams. To understand the network effect (specifically, effects of tie strength) on creativity, it integrates literature on small groups and social networks and adopts a creative-process model. An inverted U-shaped relationship between tie strength and creativity is observed, because of the mixed impacts of tie strength at different stages of the creative process. Furthermore, it explores the effect of tie configurations and finds that the skewness of tie strength distribution moderates the effect of tie strength. In addition, it also tests two competing explanations for the association between strong tie and low creativity: creativity-decline hypothesis versus cost-reduction hypothesis. Finally, there is no evidence that collaboration networks would raise the visibility of previously published papers, but there is a significant prestige effect in gaining citations.

conhecimento. Na economia baseada no conhecimento, o processo de inovação
ganha complexidade. As idéias para a inovação podem vir de fontes internas e
externas à firma ou mesmo de outras esferas institucionais, como a universidade; as
inovações originadas nas organizações tendem a ser utilizadas em diferentes
contextos, particularmente em ambientes menos compromissados com os usos
tradicionais das tecnologias e produtos existentes. O Modelo de Inovação da Hélice

introdução de inovações descontínuas nas sociedades baseadas no conhecimento,
compartilhando com a indústria e o governo a liderança do processo de inovação. O
Modelo de Inovação Aberta trata a área de P&D como um sistema aberto. Esse

Full textAbstract:
Un système de systèmes est un système dont les composants sont eux-mêmes des systèmes indépendants, tous communiquant pour atteindre un objectif commun. Lorsque ces systèmes sont mobiles, il peut être difficile d'établir des connexions de bout-en-bout. L'architecture mise en place dans de telles situations est appelée réseau tolérant aux délais. Les données sont transmises d'un système à l'autre – selon les opportunités de communication, appelées contacts, qui apparaissent lorsque deux systèmes sont proches – et disséminées dans l'ensemble du réseau avec l'espoir que chaque message atteigne sa destination. Si une donnée est trop volumineuse, elle est découpée. Chaque fragment est alors transmis séparément.Nous supposons ici que la séquence des contacts est connue. On s'intéresse donc à des applications où la mobilité des systèmes est prédictible (les réseaux de satellites par exemple). Nous cherchons à exploiter cette connaissance pour acheminer efficacement des informations depuis leurs sources jusqu'à leurs destinataires. Nous devons répondre à la question : « Quels éléments de données doivent être transférés lors de chaque contact pour minimiser le temps de dissémination » ?Nous formalisons tout d'abord ce problème, appelé problème de dissémination, et montrons qu'il est NP-difficile au sens fort. Nous proposons ensuite des algorithmes pour le résoudre. Ces derniers reposent sur des règles de dominance, des procédures de prétraitement, la programmation linéaire en nombres entiers, et la programmation par contraintes. Une partie est dédiée à la recherche de solutions robustes. Enfin, nous rapportons des résultats numériques montrant l'efficacité de nos algorithmes<br>Systems of systems are supersystems comprising elements which are themselves independent operational systems, all interacting to achieve a common goal. When the subsystems are mobile, these may suffer from a lack of continuous end-to-end connectivity. To address the technical issues in such networks, the common approach is termed delay-tolerant networking. Routing relies on a store-forward mechanism. Data are sent from one system to another – depending on the communication opportunities, termed contacts, that arise when two systems are close – and stored throughout the network in hope that all messages will reach their destination. If data are too large, these must be split. Each fragment is then transmitted separately.In this work, we assume that the sequence of contacts is known. Thus, we focus on applications where it is possible to make realistic predictions about system mobility (e.g. satellite networks). We study the problem of making the best use of knowledge about possibilities for communication when data need to be routed from a set of systems to another within a given time horizon. The fundamental question is: "Which elements of the information should be transferred during each contact so that the dissemination length is minimized"?We first formalize the so-called dissemination problem, and prove this is strongly NP-Hard. We then propose algorithms to solve it. These relies on different dominance rules, preprocessing procedures, integer-linear programming, and constraint programming. A chapter is dedicated to the search for robust solutions. Finally experimental results are reported to show the efficiency of our algorithms in practice

Full textAbstract:
The business network that is linked to flexibility, aggressiveness and strategy has become increasingly important in recent years. Several studies suggest that such networks potentially have a profound impact on firm performance, including Small and Medium-sized Enterprises (SMEs). The role of SMEs in enhancing global and local economic growth is undeniable, particularly in the context of developing countries such as Malaysia. Although numerous researches have been conducted in this field, the majority of them limit their focus to the relationship between firm capabilities (i.e. innovation and dynamic capabilities) and firm performance in specific industries. Research on the synergy impact of business networks, innovation and dynamic capabilities on SME performance remains scarce. This has become a significant gap, which this research seeks to address. This research investigates the roles of dynamic capabilities and innovation capabilities as a moderator and mediator in the relationship between business networks and firm performance, based on the model developed from the concepts of the Resource Base View (RBV) and Dynamic Capability (DC) theories. The model was justified through the Structural Equation Modelling (SEM) technique using AMOS version 23. Taking Malaysia as a research context, the model was tested against a total of 463 SMEs across different industries and categories (i.e. micro, small, and medium SMEs) through face-to-face surveys with 130 owners, 41 CEOs, 79 managers and 213 executives. This study presents five important findings: (1) there exists no direct relationship between business network and firm performance; (2) there exists a direct relationship between innovation, dynamic capabilities and firm performance; (3) the existence of the relationship between business network and firm performance is conditioned by innovation capabilities; (4) dynamic capabilities do not moderate the relationship between business network and firm performance; however (5) dynamic capabilities moderate the relationship between business networks and innovation capabilities. To conclude, the synergy of business networks, innovation capabilities and dynamic capabilities will significantly affect SME performance. This implies that SME performance will not be affected by the business network, as a single variable. The research offers three key contributions. Firstly, it enhances our understanding of the important synergies between business networks, innovation capabilities and dynamic capabilities in elevating SME firm performance. Second, the findings provide a new perspective on how the application of RBV and DC theories can be used as a conceptual lens to analyse the factors affecting SME performance. Lastly, the result signposts practical approaches for SME decision-makers by providing assistance to boost firm performance.

Bevor diese in der Praxis umgesetzt werden können, müssen Fragen zur Beschreibung der Wärmequellen und zur Wärmeübertragung beantwortet werden. Außerdem bedarf die Umsetzung der Konzepte in den CNC-Steuerungen effizienter Verfahren zur Modellierung und Simulation der thermisch bedingten Strukturverformung. Für die Entwicklung und Bewertung der Korrekturverfahren sowie zur Berechnung der notwendigen Achs-Korrekturen ist die Systemsimulation u. a. an einem prozessaktuelle Werkzeugmaschinenabbild erforderlich.

Full textAbstract:
There is no sustainability without responsibility. This research considers the connection between collaboration and responsibility. Responsible tourism has been discussed together with sustainable tourism, but who is responsible for increasing sustainability have not been researched widely. The research focus is on the nature tourism network. The tourism network consists of multiple public and private stakeholders with different agreements. All the stakeholders have their agendas, but sustainability can be seen as a common goal for each stakeholder in the nature tourism network. The question is how to implement more sustainability within tourism stakeholders and how much public-private partnerships affect the responsibility of sustainability. The qualitative research was done by mixed methods. The survey for SMEs and semi-structured interviews for SMEs and DMOs. The research area in coastal Finland includes multiple nature destinations which are owned by the state. In the previous research, it was stated that a sustainable tourism destination needs collaboration. In this research was found that SMEs cannot work without cooperation, especially in nature-based tourism destinations. The purpose of this paper was to see how the quality of collaboration between the stakeholders influences taking responsibility for sustainability actions. The lack of communication and cooperation between the public-private sector may lead to misunderstandings in sustainable tourism cooperation. Miscommunication of the delegation for the responsibilities affects the success of the sustainability implementations. This research highlights the importance of efficient stakeholder management and future research on sharing responsibility for achieving sustainability in the tourism sector.

Full textAbstract:
In the summer of 2015, the East Tennessee State University (ETSU) College of Public Health and regional health systems serving 29 counties in Northeast Tennessee and Southwest Virginia began the process of identifying a set of high-impact health programs for inclusion in a ten-year regional plan to break the cycle of inter-generational poor health outcomes in this region. It was decided that selection of effective health improvement programming must be driven by a comprehensive and deliberate effort to garner input from communities and stakeholders across the region. More than 170 professionals representing 96 health-related agencies volunteered to form steering committees around four topic areas: healthy children and families, population health, mental health and addictions, and research and academics. Each committee was tasked with; 1) providing information to the health systems on regional health priorities, 2) identifying effective approaches to addressing them, and 3) pinpointing opportunities for cross-sector collaboration. Community input was secured by holding meetings in ten area counties using the World Café model; a format chosen to encourage and facilitate discussion between participants around their local community's health concerns. In addition to priority setting for the 10-year plan, cross-sector commitment and community buy-in was established during this process that will serve as the basis for organizational planning of a proposed accountable care community (ACC). Challenges and opportunities uncovered during our efforts to improve regional health outcomes through a collaborative approach may benefit other communities working on similar projects.

Full textAbstract:
Social networks are commonly seen as a global trend that allows users to search and
contact others with similar interests, write a post, reply, like or share content, create
groups and organize events. This said, there is much more that can be done to exploit
the full potential of social media. In order to improve the business, providing
employees, customers and partners the best tools to cooperate and gain value from
the whole community, many organizations are taking the matter in their own hands,
using Enterprise Social Networks. Close analysis of case studies and comprehensive
statistics shows why it is important to pursue this path. At CERN, the European
Organization for Nuclear Research, where the number of employees, students and
volunteers that everyday work in partnership both on site and through the network
reaches the thousands, a new kind of platform has been deployed, able to exploit the
social knowledge of the personnel. The thesis will describe the case study of CERN
to understand not only why it is essential to become a social organization but also how
a social environment can be developed. The last chapters will focus on examining my
work on the platform, considering a mobile responsive design, realized to make the
environment adapt to any screen size, an integrated resource planning tool, which
gives the scientists the mean to easily manage the everyday work on the particle
accelerators, and the platform’s Application Programming Interface, which allows
anyone with the right credentials to include content from the enterprise social network
into a personal or departmental webpage, giving everyone an even easier way to
participate.

Full textAbstract:
A shift has occurred in the traditional type of centralised government control to a more multilevel type of governing referred to as governance. The change from government to governance can be illustrated with an emphasis on networks and social capital enhancement. In higher education this is enveloped through a larger emphasis on institutionalisation of collaboration between the higher education institutions (HEI) and the surrounding environment. In lieu of large block grants come financial incentives through semi-governmental agencies embracing collaboration projects between industry and HEI as well as municipalities.` This licentiate thesis objective is to study the collaboration task’s practical implication on undergraduate education in terms of social capital enhancement and research and teaching links. This is reported in two articles that elaborate on social capital establishment through a policy program and whether policy programs focusing on research collaborations also have an effect on undergraduate education by improving research and teaching links. In general, the findings of this thesis indicate that semi-governmental policy programs have a positive effect on establishing new social capital between regional HEI, industry and municipalities, and that semi-governmentally financed research profiles also have a positive effect on undergraduate education by introducing a link to research outside and within the HEI.<br>QC 20110117

Esta dissertação trata da criação e do desenvolvimento de uma rede de leitura, com crianças da quarta série, de uma escola estadual, na cidade de São Paulo. O autor do trabalho, professor da turma em questão, desenvolveu sua proposta durante um ano letivo e reflete sobre os resultados obtidos. Descreve as etapas percorridas, bem como as situações envolvendo atos de leitura e a relação das crianças com diferentes tipos de textos e produtos culturais. Ao longo da dissertação são discutidas concepções de leitura, além de conceitos chaves do trabalho, como protagonismo cultural e apropriação cultural. A utilização de metodologia colaborativa permitiu a coleta de dados qualitativos relevantes, expostos sob forma narrativa. Diálogos são reconstituídos, assim como descritas minuciosamente diferentes situações cotidianas vividas por professor e alunos nos quadros da rede de leitura. Os resultados indicam a importância de se conceber o ato de ler como atividade sociocultural, inscrita em tramas complexas que envolvem diálogos diversos: entre as crianças, destas com os textos e os contextos familiares, o meio circundante, as instituições culturais, como bibliotecas, livrarias, centros culturais, museus, dentre outras. Como conclusão, também, aponta-se para a importância fundamental do diálogo como método e atitude da construção colaborativa, objetivado na rede de leitura. Aponta, ainda, o papel positivo desta como instância de superação do isolamento cultural a que estão expostas muitas crianças. A rede de leitura tal como desenvolvida e exposta neste trabalho, afigura-se, assim, como dispositivo educativo e cultural com forte capacidade de atuação positiva na formação de leitores, tomados como protagonistas culturais dos processos de apropriação que se acham investidos.<br>This dissertation discusses the creation and development of a reading network, with class 4 children of a state school in the city of São Paulo. The author of this work, also a teacher of this class, developed his proposal during a school year and reflects on the results obtained. He describes the steps followed as well as situations involving reading and the relationship of the children with different types of texts and cultural products. Throughout the dissertation, reading conceptions and the main concepts of this work, such as cultural protagonism and cultural appropriation are discussed. The employment of a collaborative methodology permitted the collection of relevant qualitative information, displayed in a narrative form. Dialogs are reconstructed and daily situations encountered by the teacher and students are meticulously described on the reading network notice boards. The results indicate the importance of recognizing reading as a sociocultural activity, inscribed into complex actions that involve a diversity of dialogs: between the children, with the texts and family contexts, the surrounding environment, the cultural institutions like libraries, book stores, cultural centers, museums, among others. In conclusion, the fundamental importance of dialog as a method and attitude towards constructive collaboration, an objective of the reading network, is discussed. Its positive role as a resort to the cultural isolation to which many children are exposed is also pointed out. The reading network, as developed and disclosed in this work, appears as an educative and cultural device with a strong capacity for a positive performance in the formation of readers, considered to be cultural protagonists of the appropriation processes that are invested.

Full textAbstract:
This thesis challenges core assumptions associated with the peer production of culture using the web-based collaborative film production platform Wreckamovie to understand how peer production works in practice. Active cultural participation is a growing political priority for many governments and cultural bodies, but these priorities are often implemented without a basis in empirical evidence, making it necessary for rigorous scholarship to tackle emerging networked cultural production. Existing work portrays peer production efforts as unrealistically distinct from proprietary, market-based production, incorrectly suggesting that peer production allows distributed, non-monetarily motivated, collaboration between self-selected individuals in hierarchy-free communities. In overcoming these assumptions, this thesis contributes to the development of a consolidated theoretical framework encompassing the complicated and multifaceted nature of networked cultural production. This theoretical framing extends Bourdieu’s theory of cultural production and reconciles it with Becker’s Art Worlds framework, and further embeds and draws on Benkler’s notion of commons-based peer production. Concretely, this research tackles the emergence of new collaborative production models enabled by networked technologies, and theorizes the tensions and challenges characterizing such production forms. Secondly, this thesis redefines cultural participation and considers the divisions of labour in online filmmaking materializing from the interactions between professional and non-professional filmmakers. Finally, this study considers the social economies surrounding networked cultural production, including crowdfunding, and characterizes associated conversions of capital, such as the conversion of symbolic capital into financial capital. Methodologically, this thesis employs an embedded case study strategy. It examines four feature film productions facilitated by the online platform Wreckamovie, as well as the online community within which these productions are embedded. The four production cases have completed all production stages, and have resulted in completed cultural goods during the course of data collection. This study’s findings were derived from two and half years of participant observations, interviews with 29 Wreckamovie community and production members, and the examination of archived production-related discourses (2006-2013). Ultimately, this study makes concrete proposals towards a theory of networked cultural production with clear policy implications.

In der Netzwerkgesellschaft des 21. Jahrhunderts gilt die kollaborative Verteilung und Nutzung von Information und Wissen als Schlüsselstrategie für den webbasierten Informations- und Wissenstransfer. Durch die technologischen Möglichkeiten werden technische Zugangsbarrieren weitestgehend überwunden und traditionelle Formen der Wissensvermittlung durch moderne webbasierte Lernumgebungen ergänzt. Der Umgang mit kollaborativen Lehr- und Lernszenarien im dynamischen Informations- und Wissenstransfer bildet die Grundlage für den soziokulturellen Fortschritt innerhalb der Bildungsforschung. Der Schwerpunkt dieser Arbeit lag auf der strukturellen und relationalen Analyse sozialer Organisationsstrukturen innerhalb von Wissensnetzwerken. Ziel war es, Einflussfaktoren offenzulegen, die sich auf das Innovations- und Distributionspotential von Information und Wissen innerhalb von kollaborativen Wissensnetzwerken auswirken. Es wurden dazu Interaktionsprozesse von Teilnehmern innerhalb von Diskussionsforen am Beispiel der Lernplattform OPAL – dem aktuell populärsten Lernmanagementsystem in der Hochschulbildung Sachsens, Deutschland – untersucht. Unter der Annahme, dass soziale Interaktion besonders im Umgang mit kollaborativen Medien den Bildungsablauf und der Aufbau von Wissensnetzwerken die Lehr- und Lernprozesse beeinflusst, wurden in dieser Arbeit die strukturellen Bedingungen des kollaborativen Wissensnetzwerkes in OPAL exploriert und soziale Rollenkonstrukte relational identifiziert, um die Auswirkungen kollaborativer Aktivitäten auf den Informations- und Wissenstransfer in Wissensnetzwerken zu erklären. Es wurden vornehmlich beziehungsorientierte kommunikationstheoretische Modelle zugrunde gelegt und relationale Forschungsmethoden wie SNA (Social Network Analysis) und DNA (Dynamic Network Analysis) angewandt, um eine Basis für die weiterführende Implementierung sozial vernetzter Lehr- und Lernstrategien in der Bildungsforschung zu schaffen. […]<br>In the network society of the 21st century, a key strategy for web-based exchange of information and knowledge is their collaborative distribution and use. Technical hurdles of access are mostly being overcome with technological advances and traditional forms of passing on knowledge are being complemented by modern, e-learning environments. Within research into education, the foundation for socio-cultural progress is formed by involvement with collaborative teaching and learning scenarios in a dynamic exchange of information and knowledge. The emphasis of this work lay in the analysis of structures and relationships of social organisations within knowledge networks. The aim was to describe the exchange of information and knowledge in collaborative learning systems and to explore its influence on the potential for innovation and distribution of information and knowledge. A study was undertaken of the interaction of participants in discussion forums as exemplified by the learning platform OPAL – currently the most popular learning management system in secondary school education in Saxony, Germany. On the assumption that social interaction, particularly involving collaborative media, the progress of education and the construction of knowledge networks do influence teaching and learning processes, this work explored the structural conditions of OPAL's collaborative knowledge network and identified relationships between social role constructs in order to explain the effect of collaborative activities on the process of diffusion of information and knowledge in knowledge networks. Primarily the study was based on relationship oriented sociological models and communication theory models, and research methods for relationships, including SNA (Social Network Analysis) and DNA (Dynamic Network Analysis) were applied, so as to create a basis for further implementation of social network teaching and learning strategies in educational research.

O estudo apresenta um panorama da produção e das redes de colaboração científica de docentes dos cursos de Biblioteconomia de Instituições de Ensino Superior do Estado de São Paulo e as interseções entre a produção e comunicação científica dos docentes vinculados apenas a cursos de graduação e aqueles vinculados simultaneamente à programas de pós-graduação. Partiu-se do pressuposto que a interação entre ensino e pesquisa é fundamental para garantir um ensino de qualidade e que, na Ciência da Informação, a pesquisa não pode prescindir do conhecimento produzido no campo profissional, celeiro fundamental para novas pesquisas e avanço do conhecimento. Trabalhou-se com a hipótese de que, embora a pesquisa no Brasil seja desenvolvida principalmente nos programas de pós-graduação stricto sensu, docentes dos cursos de Biblioteconomia não integrados aos programas de pós-graduação também desenvolvem pesquisas, mas com foco nas experiências profissionais, cujo lócus de divulgação e discussão são os eventos acadêmico-profissionais, que possibilitam redes de colaboração diferentes daquelas propiciadas pelos fóruns de discussões da pesquisa na pós-graduação e representam potencial importante de produção de conhecimento para reflexão e sistematização não apenas de profissionais, mas também de compartilhamento entre docentes da graduação e da pós-graduação. Utilizou-se a metodologia de Análise de Redes Sociais (ARS) em conjunto com técnicas bibliométricas. A produção científica de 116 docentes ativos foi coletada na Plataforma Lattes e complementada com informações do ResearchGate e Google Acadêmico, num período que abrange as duas últimas avaliações da Capes (triênio 2010-2012 e o quadriênio 2013-2016). Resultados confirmam parcialmente a hipótese e mostram que dos 46 docentes não vinculados aos programas de pós-graduação, onze (23,9%) não apresentaram qualquer produção no período analisado. Tal dado é preocupante, considerando que as alterações do mundo do trabalho, com aspectos de jurisdição das profissões em discussão, têm colocado contínuos desafios para as profissões de informação. A pesquisa revela também que 90,6% dos docentes dos cursos de Biblioteconomia do Estado de São Paulo (vinculados ou não aos programas de pós-graduação) têm se preocupado com pesquisa e apresentação de trabalhos de caráter científico, acadêmico ou profissional e mantêm redes de colaboração com diferentes autores, embora os aspectos de internacionalização estejam restritos a poucas instituições, notadamente espanholas. A pesquisa contribui para a compreensão da colaboração científica dos docentes dos cursos de Biblioteconomia do estado de São Paulo, comparando os comportamentos dos docentes vinculados e aqueles não vinculados aos programas de pós-graduação e possibilitou externalizar a estreita ligação entre a atividade de pesquisa e a atividade profissional na área de Biblioteconomia, além da relação intrínseca entre o ensino e a pesquisa.<br>The study presents an overview of the production and scientific collaboration networks from professors of the courses of Library Science of Institutions of Higher Education of the State of São Paulo and the intersection between the production and scientific communication of the teachers linked only to graduate courses and those linked both to graduate and posgraduate. It was assumed that the interaction between learning and research is essential to assure a high-quality learning and that, on the Information Science, the research can\'t ignore the knowledge produced on the professional field, which is a main silo for new researches and the advancement of knowledge. It was considered the hypothesis that, while research in Brazil is developed mainly on the posgraduate stricto sensu, the professor from the Library Science courses not integrated to the posgraduate also develop researches, but with a focus on the professional experiences, whose locus of disclosure and discussion are the academic/professional events, that allow collaboration networks different from those provided by the forums of research discussion on the graduation and represent an important potential of knowledge production for thinking and systematization, not only from professionals, but from sharing between graduate and posgraduate teachers. It was used the Social Network Analysis methodology, along with Bibliometric techniques. The scientific production 116 active professors was collected from the Lattes Platform and implemented with information from ResearchGate and Google Academics, on an interval that comprehends the last two assessments from Capes (three-year period from 2010-2012 and four-year period from 2013-2016). The results confirm, in part, the hypothesis and show that, from the 46 teachers that are not linked to the posgraduate, eleven (23,9%) did not present any publication on the analyzed interval. This is an alarming data, considering that the changes on the workplace, with jurisdictional aspects of the professions under discussion, have placed many challenges for the information professions. The research also shows that 90,6% of the teachers from Library Science on the state of São Paulo (whether linked to the posgraduate or not) have cared about the research and presentation of scientific, academic or professional works, and they maintain collaboration networks with different authors, although the internationalization process is limited to a few institutions, mainly the Spanish ones. The research contributes to the compreension of scientific collaboration between professors of the courses of Library Science of Higher Education of the State of São Paulo, comparing the behavior of teachers integrated and not integrated to the posgraduate and enable to outsource the close connection between research activities and professional activities of Library Science, and also between learning and research in this area.

1 EINLEITUNG
Der Einsatz von Enterprise 2.0-Lösungen steht noch am Anfang. So nutzen nur ca. 20 % der Unternehmen in den USA und Europa Social Software-Werkzeuge wie Blogs, Wikis oder Foren [7]. Nach [3] geht es bei Enterprise 2.0 darum, die Ideen und Konzepte des Web 2.0 und von Social Software zu verstehen und auf die Zusammenarbeit in Unternehmen zu übertragen. Viele Unternehmen haben Schwierigkeiten bei der Integration solcher Lösungen, wodurch die Zugänglichkeit und Handhabbarkeit der Informationen im Unternehmen leidet. In einem konkreten Anwendungsfall sollen Lösungen gefunden werden, um das Gewahrsein der Informationen bestehender Social Software-Systeme und die Zusammenarbeit in Entwicklungsabteilungen zu verbessern.

Full textAbstract:
La méthodologie de l’évaluation en psychothérapie s’est longtemps limitée aux résultats issus d’essais cliniques comparatifs de groupes. L’objectif, engagé dans les années 2000, de comprendre ce qui cause son efficacité a engagé un renouvellement méthodologique. Son application concrète est peu documentée. La première partie présente, à partir d’une revue de la littérature centrée sur l’introduction de la recherche sur le processus associée aux résultats, comment le paradigme interactionnel multifactoriel de la psychothérapie a stimulé le développement de méthodes adaptées à la complexité et à l’observation en conditions naturelles. La seconde partie introduit autour de cinq axes principaux les questions méthodologiques générales et spécifiques de cette nouvelle orientation : 1. une épistémologie interactionnelle et transactionnelle ; 2. Un recentrage sur les études mixtes intensives de cas ; 3. Une investigation clinique et théorique multifocale des processus et mécanismes de changement ; 4. une forte relation clinicien-chercheur ; 5. une approche statistique innovante. La troisième partie expose l’expérience et les questions soulevées par la mise en œuvre de ce programme dans le cadre d’un réseau de recherche clinique centré sur les pratiques, du recueil des données jusqu’à l’analyse des processus et mécanismes de changement, et les résultats qui en sont issus. La quatrième partie présente une revue détaillée de la littérature. Ce travail devrait favoriser les collaborations avec les disciplines connexes et l’efficience des traitements par une meilleure connaissance des conditions et des mécanismes de changement associée au développement d’une base de données issue d’études de cas<br>The methodology of assessment in psychotherapy has long been limited to results from comparative group clinical trials. The objective, expressed in the 2000s, to understand what is causing its effectiveness has involved a methodological renewal. Its concrete application is poorly documented. The first part presents, from a review of the literature focusing on the introduction of research on the process associated with outcomes, how the multifactorial interactional paradigm of psychotherapy has stimulated the development of methods adapted to the complexity and observation in natural conditions. The second part introduces the general and specific methodological questions of this new orientation around five main axes: 1. an interactional and transactional epistemology; 2. A refocusing on intensive mixed case studies; 3. A multifocal clinical and theoretical investigation of the processes and mechanisms of change; 4. a strong clinical-researcher relationship; 5. an innovative statistical approach. The third part presents the experience and issues raised by the implementation of this program as part of a practice-oriented clinical research network, from data collection to analysis of processes and mechanisms of change, and results. The fourth part presents a detailed review of the literature. This work should foster collaborations with related disciplines and treatment efficiency through a better understanding of the conditions and mechanisms of change associated with the development of a case study database

Full textAbstract:
Social networks have been evolving over the past few years, leading to a rapid increase in the number and complexity of relationships among their entities. In this research, we focus on a large scale dataset known as the Digital Bibliography and Library Project or DBLP, which contains information on all publications that have been published in computer and information science related journals and conference proceedings. We model the DBLP dataset as a social network of research collaborations. DBLP is a structured and dynamic dataset stored in the XML file format; it contains over 850,000 authors and 2 million publications, and the resulting collaboration social network is a scale-free network. We define DBLP collaboration social network as a graph that consists of researchers as nodes and links representing the collaboration or co-authorship relationships among the researchers. In this work, we implement a data analysis algorithm called Multidimensional Scaling (MDS) to represent the degree of collaboration among the DBLP authors as Euclidean distances in 2-dimensional space in order to analyze, mine and understand the relational information in this large scale network in a visual way. MDS is a useful technique for data visualization and graph drawing methods, but it has high computational complexity for large scale graphs such as the DBLP graph. Therefore, we propose different solutions to overcome this problem, and improve the MDS performance. In addition, as the quality of the MDS result is measured by a metric known as the stress value, we use the steepest descent method to minimize the stress in an iterative process called stress optimization in order to generate the best geometric layout of the graph nodes in 2-dimensional space. We also propose a solution to further enhance the graph visualization by partitioning the graph into sub-graphs and using repelling forces among nodes within the same sub-graph. Finally, we developed a new visualization tool that can handle the large scale of the DBLP graph, and provides the user a number of significant features that allow them to explore, navigate and sift for information through the graph, such as graph scaling and graphical search functionality.<br>UOIT

Full textAbstract:
碩士<br>元智大學<br>資訊社會學研究所<br>93<br>The Information technology revolution not only has a great influence on the globalization and networked production paradigm, but also changes the logic of research development in the science community. Scientific researches gradually became more cross-disciplined and collaborative. The first objective of this study attempts to observe the change pattern of current research alliances after adapting ICTs. Does CMC enhance collaboration and transform the social network of the scientific community? To what extent, would individual scientific productivity increase after joining collaboration?
A web-based survey of 23 samples from the "National IPv6 Development Program" in Taiwan was conducted. And we used citation analysis to draw the network of co-author publication in IPv6 team. The result shows that CMC and phone are both most frequently used for communication within the groups and CMC can actually enhance weak ties and has positive effects on the productivity of academic publication. However, CMC does not increase the heterogeneity of academic field and disciplines, and the participants of IPv6 still bond with the university that they belong. Strong ties play a very significant role in facilitating information exchange within the network. Moreover, no matter what kind of information they exchange, scholars have higher productivity if only they interact more frequently with other team members. In the Information discipline, we observe that strong ties are important for scholars to share useful information and possibly gain higher research productivities.

碩士<br>國立臺北大學<br>經濟學系<br>106<br>Library in campus can easily be underused. To boost book circulation, a good recommendation system can help. This paper adopts the traditional collaborative filtering recommendation system and extends it to the neural network architecture collaborative filtering system. It can extract the feature values of students’ book borrowing in a linear model on the collaborative filtering system and, at the same time, take advantage of the neural network architecture to extract the hidden message features to predict the student's relevance matrix for book preferences. Apply the algorithm to the book borrowing data from National Taipei University library, we are able to build a recommendation system that out performs traditional simple popularity recommendation.
