Les sciences humaines et le progrès social ne peuvent pas se poursuivre sans collaboration. Avec le développement rapide des technologies de l'information et la popularité des appareils intelligents, le travail collaboratif est beaucoup plus simple et plus fréquents que jamais. Les gens peuvent travailler ensemble sans tenir compte de leur emplacement/ location géographique ou de la limitation de temps. Les environnements de travail de collaboration basés sur le Web sont conçus et consacrés à supporter/soutenir le travail individuel et le travail en groupe dans divers domaines: la recherche, les affaires, l'éducation, etc. N'importe quelle activité dans un système d'information produit un ensemble de traces. Dans un contexte de travail collaboratif, de telles traces peuvent être très volumineuses et hétérogènes. Pour un Environnement de Travail Collaboratif (ETC) typique Basé sur le Web, les traces sont principalement produites par des activités collaboratives ou des interactions collaboratives et peuvent être enregistrées. Les traces modélisées ne représentent pas seulement la connaissance, mais aussi l'expérience acquise par les acteurs via leurs interactions mutuelles ou les interactions qu'ils ont avec le système. Avec la complexité croissante de la structure de groupe et les besoins fréquents de collaboration, les interactions existantes deviennent de plus en plus difficiles à saisir et à analyser. Or, pour leurs travaux futurs, les gens ont souvent besoin de récupérer des informations issues de leurs activités de collaboration précédentes. Cette thèse se concentre sur la définition, la modélisation et l'exploitation des différentes traces dans le contexte d'Environnement de Travail Collaboratif et en particulier aux Traces Collaboratives dans l'espace de travail partagé de groupe (ou l'espace de travail collaboratif). Un modèle de traces de collaboration qui peuvent efficacement enrichir l'expérience du groupe et aider à la collaboration de groupe est proposé et détaillé. Nous présentons ensuite et définissons un type de filtre complexe comme un moyen possible d'exploiter ces traces. Plusieurs scénarios de base d'exploitation des traces collaboratives sont présentés. Pour chacun d'entre eux, nous présentons leurs effets et les avantages procurés par ces effets dans l'environnement de travail collaboratif. En effet, un cadre de l'exploitation des traces général est introduit et nous expliquons mis en œuvre dans un ETC. Trois approches collaboratives générant des traces sont discutées à l'aide d'exemples: l'Analyse SWOT, l'intégration de modèle de maturité de la capacité (CMMI) et le Système de Recommandation de Groupe. Une expérimentation de ce modèle a été réalisée dans le cadre de la plate-forme collaborative E-MEMORAe2.0. Cette expérience montre que notre modèle de trace collaborative et le cadre d'exploitation proposé pour l'environnement de travail collaboratif peuvent faciliter à la fois le travail personnel et de groupe. Notre approche peut être appliquée comme un moyen générique pour traiter différents sujets et problèmes, qu'il s'agisse de collaboration ou de l'exploitation des traces laissées dans un ECT. / Human science and social progress cannot continue without collaboration. With the rapid development of information technologies and the popularity of smart devices, collaborative work is much simpler and more common than ever. People can work together irrespective of their geographical location or time limitation. In recently years, Web-based Collaborative Working Environments (CWE) are designed and devoted to support both individual and group work to a greater extent in various areas: research, business, learning and etc. Any activity in an information system produces a set of traces. In a collaborative working context, such traces may be very voluminous and heterogeneous. For a typical Webbased Collaborative Working Environment, traces are mainly produced by collaborative activities or interactions and can be recorded. The modeled traces not only represent knowledge but also experience concerning the interactive actions among the actors or between actors and the system. With the increasing complexity of group structure and frequent collaboration needs, the existing interactions become more difficult to grasp and to analyze. And for the future work, people often need to retrieve more information from their previous collaborative activities. This thesis focuses on defining, modeling and exploiting the various traces in the context of CWE, in particular, Collaborative Traces (CTs) in the group shared/collaborativeworkspace. A model of collaborative traces that can efficiently enrich group experience and assist group collaboration is proposed and detailed. In addition, we introduce and define a type of complex filter as a possible means to exploit the traces. Several basic scenarios of collaborative traces exploitation are presented describing their effects and advantages in CWE. Furthermore, a general traces exploitation framework is introduced and implemented in CWE. Three possible traces based collaborative approaches are discussed with comprehensive examples: SWOT Analysis, Capability Maturity Model Integration (CMMI) and Group Recommendation System. As a practical experience we tested our model in the context of the E-MEMORAe2.0 collaborative platform. Practical cases show that our proposed CT model and the exploitation framework for CWE can facilitate both personal and group work. This approach can be applied as a generic way for addressing different types of collaboration and trace issues/problems in CWE.

This study contributes an original, practice-based analysis of knowledge brokering in inter-organisational communities of practice in the not-for-profit sector. Defining characteristics of the not-for-profit sector include its social values, principles and practices. Existing literature understates or overlooks the significance of values and principles that are manifested in and enlivened through every day social practices and practitioner encounters. The study contributes by presenting knowledge brokering as a knowledge sharing intervention which integrates people, processes, values and principles into practice. Knowledge brokering and other practice interventions in the not-for-profit sector have to align with its social mission, if they are to be compatible and effective. This is especially so in multi-agency partnerships and inter-organisational communities of practice where collaboration and co-existence rather than assimilation are the primary objectives. This study finds that values-compatible knowledge brokering interventions, boundary bridging, co-creation, common artefacts and knowledge sharing, enable inter-organisational communities of practice to evolve without sacrificing individual autonomy. Foundational knowledge brokering literature emphasises the structural position of the knowledge broker, their knowledge superiority and the benefits they accrue by operating on the periphery of a social network. The study contributes by arguing that knowledge brokering processes and roles can be examined through an alternative practice lens with the knowledge broker as an internal co-practitioner located within a network. The study was carried out in a new, time-limited multi-agency partnership project in the not-for-profit sector. The partnership constituted an inter-organisational community of practice comprising advice, information and support agencies that had agreed to work collaboratively to improve local services. The author was employed as the project s Knowledge Management Officer and carried out the study over a two year period using an insider action research approach. As an insider practitioner-researcher, the author contributed to the project s objectives, worked collaboratively with practitioners and gathered rich data. Action and research occurred simultaneously and the iterative processes enabled the cumulative learning to inform, develop and analyse the practice. The combination of using insider action research approach, an examination of knowledge brokering as a practice intervention and a multi-agency, not-for-profit setting, makes this a unique practice-based study untapping knowledge management lessons from the not-for-profit sector.

Wikis are a popular collaboration technology. They support the collaborative editing of web pages through a simple mark-up language. Mobile devices are becoming ubiquitous, powerful and affordable. Thus it is advantageous for people to get the benefits of wikis in a mobile setting. However, mobile computing leads to its own challenges such as limited screen size, bandwidth, memory and battery life; they also have intermittent connectivity due to the mobility and the coverage of network. I investigate how wikis can be made mobile; that is how wiki forms of collaborative editing can be achieved through mobile devices such as PDAs and smart phones. A prototype mobile wiki has been created using .NET, which addresses these issues and enables simple collaborative working whilst on and offline through smart mobile devices. A cut down wiki runs on the mobile device. This communicates with a main central wiki to cache pages for off line use. When sitting in a powered cradle eager, downloading and synchronization of pages is supported. During mobile operation, pages are cached lazily on demand to minimize power use and to save the limited and expensive bandwidth. On re-connection, offline edited as well as new pages are synchronized with the main wiki server. Finally a pluggable page rendering engine enables pages to be rendered in different ways to suit different sized screens.

Partnering som arbetssätt har funnits i Sverige sedan slutet av 90-talet och kommit att bli allt vanligare, särskilt inom offentligt byggande. Arbetssättet är en reaktion på det traditionella förfarandet som kritiserats för att vara fragmentiserat och innebära dåligt utnyttjande av kunskap och skapa många konflikter. I en integrerad organisation och med en iterativ process utvecklar och genomför alla aktörer projektet med full transparens i alla delprocesser i syfte att maximera värdet av slutprodukten och sätta kundens behov i centrum. ByggDialog är ett företag som från start specialiserat sig på partnering och som organiserar och leder produktbestämningsskedet ofta kallat Fas 1, varefter man också samordnar alla entreprenörer och utför byggentreprenaden med egen arbetskraft. ByggDialog vill utveckla sitt arbete i Fas 1 och skapa en så flödeseffektiv process som möjligt för att komma till produktion inom rimlig tid. Detta är viktigt då man strävar efter effektivitet i allmänhet men också för att det ska vara möjligt att med god säkerhet och små avvikelser prognostisera resursbehov, tillväxttakt och resultat. Flödeseffektivitet är ett begrepp hämtat från Lean-teorin som har sitt ursprung i Toyotas bilfabriker. Det handlar om att skapa en process där icke värdeskapande aktiviteter elimineras och fokus ligger på densiteten i värdeöverföringen till produkten och dess flöde. Syftet med denna rapport är att applicera dessa teorier på ByggDialogs processer i Fas 1 och att genom intervjuer med personer med stor erfarenhet kartlägga icke värdeskapande aktiviteter i Fas 1. I studien ingick också att föreslå åtgärder till förbättrad flödeseffektivitet. Det gjordes även en ansats till att beräkna flödeseffektiviteten i ett antal genomförda projekt i syfte att utreda möjligheten till lämplig indikator för företagets förbättringsarbete av Fas 1. Det visade sig att flödeseffektiviteten i Fas 1 sammanfattningsvis kan påverkas positivt genom bland annat öppenhet, integrerade organisationer, standardiserade arbetssätt, iterativa projekteringsmetoder och tydlig projektledning. En indikator för flödeseffektivitet som beaktar kvoten mellan värdeskapande tid och genomloppstid genom BTA visade sig vara komplex att ta fram. En framkomlig väg är dock att endast låta indikatorn avspegla genomloppstid genom BTA eller produktionskostnad. Fördjupade studier rekommenderas ByggDialog för att söka den mest användbara metoden för uppföljning och mätning av effektiviteten i Fas 1. / Partnering as a working method has existed in Sweden since the late 90s and has become increasingly common, especially in public construction. The way of working is a reaction to the traditional procedure that has been criticized for being fragmented and misleading knowledge and creating many conflicts. In an integrated organization and with an iterative process, all players develop and implement the project with full transparency in all sub-processes to maximize the value of the product and put the customer's needs in focus. ByggDialog is a company that from the start specializes in partnering and who organizes and leads the design phase often called Phase 1, after which one also coordinates all contractors and performs the construction with their own workforce. ByggDialog wants to develop their work in Phase 1 and create a process as flow-efficient as possible to reach production within a reasonable time. This is important as one strives for efficiency in general, but also for it to be possible to forecast resource needs, growth rates and results with good precision and small deviations. Flow efficiency is a concept derived from Lean theory that originates from Toyota's car factories. It is about creating a process where non-value-creating activities are eliminated, and the focus is on the density of the value transfer to the product and its flow. The purpose of this report is to apply these theories to ByggDialog's processes in Phase 1 and to survey non-value-creating activities in Phase 1 through interviews with people with great experience of Phase 1. The study also included proposing measures for improved flow efficiency. An effort was also made to calculate the flow efficiency in several completed projects to investigate the possibility of an appropriate indicator for the company's improvement work on Phase 1. In summary, it turned out that flow efficiency in Phase 1 can be positively affected by openness, integrated organizations, standardized working methods, iterative design methods and distinct project management. An indicator of flow efficiency that considers the ratio of value-creating time and throughput divided by BTA proved to be too complex to develop. A viable route, however, is to only let the indicator reflect the throughput divided by BTA or production cost. In-depth studies are recommended for ByggDialog to seek the most useful method for monitoring and measuring the effectiveness of Phase 1.

An intoxicated police employee can never keep the community safe and secure, as mandated by law enforcement prescripts. However, limited attention is given to harmful or hazardous substance abuse or the binge drinking habits of police employees. Substance abuse being a ‘culture’ in law enforcement agencies and the maintenance of the blue wall of silence as a protective measure necessitates scientific research to explore how a collaborative working relationship between the occupational social worker and especially First Line Managers (FLMs) can contribute to addressing this phenomenon in a timeous manner. The researcher applied a quantitative research approach and utilised a switching replication quasi-experimental design to determine whether the collaborative working relationship between South African Police Service (SAPS) FLMs and Police Social Workers (PSWs) can be strengthened to the extent that they effectively and efficiently deal with the harmful or hazardous substance abuse or binge drinking habits of SAPS employees by exposing the FLMs to a social work intervention, namely the Sober Workplace Programme for Managers. The pre-, mid-, and posttest measurements are based on knowledge, attitude, and behaviour constructs to determine if the two hypotheses formulated were supported. The study, however, did not indicate that the Sober Workplace Programme for Managers strengthens the collaborative working relationship between the FLMs and PSWs to address the harmful or hazardous substance abuse or binge drinking habits of employees in the workplace. Alternative research and occupational social work strategies are recommended to establish if and how the Sober Workplace Programme for Managers can be implemented to strengthen the collaborative working relationship between the FLMs and PSWs to address the harmful or hazardous substance abuse or binge drinking habits of employees. / Social Work / Ph.
