Organisational knowledge creation applied to multi-practitioner arts-related practice-led research projects / Ian R. Marley

Marley, Ian January 2015 (has links)
This research investigates the theory of organisational knowledge creation as a viable model in the management of multi-practitioner arts-related practice-led research projects conducted at the North-West University, Potchefstroom Campus. In this regard Transgressions and Boundaries of the Page (2009-2012) (an interdisciplinary exploration of a practice-led research project by means of the artist’s book) is analysed according to the said theory in order to ascertain the compatibility of this theory and the projects outlined. It should be noted that the particular project is not discussed as an example of the application of the theory of organisational knowledge creation. Rather, the purpose of this research is to identify the appearance of salient aspects of the given theory in order to ascertain whether this could be an appropriate management model for future projects of this nature. Accordingly, the goal is to identify such a model that will facilitate and promote creative practice and accredited research within the History of Art, Graphic Design, and Creative Writing disciplines at the North-West Universities Potchefstroom campus. The proposed coupling of the theory of organisational knowledge creation and multi-practitioner arts-related projects by way of practice-led research is underpinned by the fact that both can be situated within the participatory paradigm due to a common conceptualisation of knowledge. This paradigm offers an extended epistemology consisting of practical, experiential, presentational, and propositional knowledge. This paradigm effectively integrates both the tacit and explicit knowledge modalities, which are fundamental to practice-led research and the theory of organisational knowledge creation. A further commonality is the fact that knowledge is considered as an interdisciplinary, subjective and socially constructed phenomenon. In the context of this research, practice-led research involves the self-reflective process, which involves the making, reading and interpretation of creative outputs in the academic milieu. This requires the utilisation of reflective practice to communicate both the tacit and explicit knowledge dimensions. Additionally the participatory paradigm, practice-led research and the theory of organisational knowledge creation advocate a knowledge process that moves through a tacit–explicit knowledge cycle. This knowledge creation cycle in the participatory paradigm and the theory of organisational knowledge creation occur in four levels. In consequence, the Transgressions and Boundaries of the Page project has been managed in four phases. It is against this background that the four knowledge conversion levels of this theory are linked with the extended epistemology of the participatory paradigm to analyse the four phases of the Transgressions and Boundaries of the Page project. The first phase of the Transgressions and Boundaries of the Page project entailed the conceptualisation, planning, and preparation during August 2008 to March 2009. This phase is analysed by means of level one of the theory of organisational knowledge creation (explicit to tacit knowledge conversion) and practical knowledge of the participatory paradigm. The second phase of the project, namely knowledge creation, took place from March 2009 to January 2010. The analysis of this phase is accomplished by means of level two of the theory of organisational knowledge creation (tacit to tacit knowledge conversion) and experiential knowledge of the participatory paradigm. The third phase of the project, namely knowledge presentation and communication, from February 2010 to July 2010 corresponds with, and is analysed by, level three of the theory of organisational knowledge creation (tacit to explicit knowledge conversion) and presentational knowledge of the participatory paradigm. The fourth knowledge formalisation and dissemination phase of the project occurred during July 2010 to December 2011. This phase is analysed by means of level four of the theory of organisational knowledge creation (explicit to explicit knowledge conversion) and propositional knowledge of the participatory paradigm. Consequently, I argued that each phase of the project correlates with the corresponding levels of the theory of organisational knowledge creation, knowledge conversion mechanisms and the knowledge modalities of the participatory paradigms. The four phases of the project and the four levels share common knowledge conversion and creation processes and goals that are attributed to the common conceptualisation of knowledge. Distinct correlations between the knowledge creation goals of the knowledge conversion levels and phases were identified. Therefore, the mechanisms used to achieve knowledge conversion and creation were applicable to the assigned management phases of the project. It was further argued that it is possible to adapt the current management approach to the more structured theory of organisational knowledge creation without negating either the tacit or explicit knowledge modalities. Consequently it is concluded that the theory of organisational knowledge creation, which is a management model normally used in the commercial business context, could be utilised to manage multi-practitioner arts related practice-led research projects more effectively in the academic context. / PhD (History of Art), North-West University, Potchefstroom Campus, 2015

Actors in Collaboration : Sociotechnical Influence on Practice-Research Collaboration

Ponti, Marisa January 2010 (has links)
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. / <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>

Examination of the toxicity and inflammatory potential of multi-walled carbon nanotubes in vitro and in vivo

Sternad, Karl Alexander January 2010 (has links)
The rise of nanotechnology industries has led to the design and production of new nano-scaled materials such as quantum dots, nano-metals, carbon nanotubes, fullerenes and a myriad of functionalised derivatives. Extensive work concerning well characterised pathogenic fibres has led to the development of a fibre paradigm that suggests respirable fibres vary in their ability to cause disease based on length and pulmonary bio-persistence. Induction of oxidative stress is also a central plank of the mechanism used to explain inflammatory, fibrotic and carcinogenic effects of fibres. The toxicity of different particle types has consistently been shown to depend upon particle size and surface area, reactive surface molecular groups, metal content, organic content and the presence of endotoxins. A growing body of work has begun to examine the potential pathogenicity of carbon nanotubes to the pulmonary system as a consequence of superficial similarities to known pathogenic particle and fibres. The aim of this thesis was to investigate the potential toxicity of two commercially manufactured multi-walled carbon nanotubes (MWCNT) compared to a panel of low and high toxicity particles and fibres. The pro-inflammatory nature of MWCNT was examined in vitro and in vivo to determine the effects they may exert in the pulmonary system. In aqueous solutions of phosphate buffered saline, saline and cell culture medium (with or without foetal calf serum supplementation) MWCNT were found to exist as tight aggregates even after sonication. Analysis of metal content of MWCNT by ICP-AES revealed the presence of a low percentage of non extractable residual iron. From analysis of MWCNT by electron spin resonance (ESR) the CNT were found to be ready producers of a free radical species, despite this MWCNT were not able to cleave plasmid DNA. Upon incubation with the alveolar epithelial cell line A549 MWCNTs did not cause noticeable toxicity but did dose dependently deplete total glutathione levels. No increase in production of the pro-inflammatory cytokine IL-8 could be detected at the level of protein or at the level of mRNA. Analysis of the levels (protein and mRNA) of the pro-fibrotic mediator TGF-β did not indicate induction of a fibrotic response to MWCNT. Neither were MWCNTs found to consistently activate the pro-inflammatory associated transcription factor nuclear factor kappa B (NF-κB). Upon instillation into the peritoneal cavity of mice MWCNT failed to induce a pro-inflammatory response in contrast to long amosite asbestos that induced an extensive inflammatory reaction. Analysis of the diaphragms of exposed animals revealed the induction by MWCNT of an apparent foreign body type reaction. Overall with limited processing and dispersion MWCNT were morphologically more akin to particles than fibres. Although apparently able to spontaneously generate ROS in aqueous solution this did not translate into a capacity to cause toxicity or a capacity to induce inflammation either in vitro or in vivo.

Influential Factors in Innovation Initiatives at a Telecom Equipment Supplier : A Study of Lead Generation and Add-on Sales’ Hindrances and Enablers

Souza, Alina, El Ghazouani, Anas January 2016 (has links)
Abstract In this research, we aim to look at the inner workings of Lead Generation and Add-on Sales through the eye of the people working directly with it. We do that with the objective of understanding what contributes positively to its success and what can cause problems or hinders it throughout all its stages from generating innovative ideas to implementing and selling them. We have chosen a qualitative method to conduct this study using an interpretive paradigm in performing our analysis of the findings. The data was collected by organizing interviews with participants that we selected in collaboration with Telco’s researchers. The interviews were recorded, transcribed and coded to form our primary data. In addition to that, we have used vast secondary data that was deemed to be relevant to the subject we were researching. After analyzing the results and findings, we look to answer the research questions, which concern the difficulties accompanying the innovative process between initiating an idea and implementing it as well as identifying the enablers and hindrances that arise during the operations of these innovative initiatives called Lead Generation and Add-on Sales. Once factors were identified, further analysis is performed to discuss if these factors are hindrances or enablers to the innovative initiatives at Telco. The frontline employees’ new business ideas (leads) or add-on sales are added as inputs to the ICT systems of this initiative and follow to subsequent phases until reach the commercialization phase in case they succeed, all the phases and processes occur through the ICT systems. In the context of this research, technology plays a key role and not only make the Lead Generation and Add-on sales processes viable but is also a factor that can either facilitate or impede potential leads or add-on sales to succeed. We put forward a model to better illustrate our findings and clarify the reasoning behind them. Despite the delimitations in terms of scope of this research, we believe that our findings and analysis can play a role in contributing to the understanding of factors that can be a barrier in the pursuit for innovation.

The process of the new inter-organizational format of social franchising from a social network theory approach : institutions, social entrepreneurship profile, social innovation and the argument of embeddedness

Zafeiropoulou, Fiori Andreas January 2013 (has links)
The inability of the public sector to satisfy social needs - like poverty alleviation, social inclusion of disadvantaged groups, unemployment, health and education - are redefining the relationship between the governments and their citizens by making the latter play an active role as the provider of the welfare state. Citizens through their entrepreneurial activity have been pulled to the third sector leading to the emergence of new organizational forms like social enterprises and social franchises. The main focus of this research study is the investigation of the new interorganizational format of social franchising which has received ‘scunt’ research attention up to now. The behaviour of actors and organizations in the social economy sector are influenced by the properties and dynamics of elements coming from the political, social, organizational and individual level. We have adopted a systems approach of social network theory. A grounded theory named Social Franchise Model (SoFraM) has been induced from an exploratory empirical mixed method study conducted at various stages and from different sources during a time frame of thirty months. Primary data were raised through six case studies in the UK and Greece, more than 143 interviews with social entrepreneurs and various stakeholders and three action research projects which were the subject of analytic induction supported by archival analysis of secondary data coming from governmental, European Commission, local authority and other sources. Our findings indicate that the formation, growth and success of social franchises is heavily shaped through: firstly, law, regulations, and incentives introduced by centralized or formal institutions- both supranational and national- as well as their driving logics; secondly, the relational and structural embeddedness of actors in networks and the social norms that subsequently emerge; thirdly, the characteristics of the individual social entrepreneurship profile; and finally elements of the social innovation model adopted. The properties of the system of informal or decentralised institutions of networks have been further explored through a pilot quantitative study on mainstream franchises in the UK and Greece. An online self-administered questionnaire has been created based on our conceptual framework of the Franchise Network Model (FNM) drawn from existing scales from literature. The findings indicate that relational and structural embeddedness of actors and organizations in networks determine choices of formation, partner selection, governance mode and the subsequent performance of franchise systems.

A framework for grid-enabling scientific workflow systems : architecture and application case studies on interoperability and heterogeneity in support for grid workflow automation

Azam, Nabeel Adeem January 2010 (has links)
Since the early 2000s, Service Oriented Architectures (SOAs) have played a key role in the development of complex applications within a virtual organization (VO) context. Grids and workflows have emerged as vital technologies for addressing the (SOA) paradigm. Given the variety of Grid middleware, scientific workflow systems and Grid workflows available, bringing the two technologies together in a flexible, reusable and generalized way has been largely overlooked, particularly from a scientific end user perspective. The lack of domain focus in this area has led to a slow uptake of Grid technologies. This thesis aims to design a framework for Grid-enabling workflows, which identifies the essential technological components, how these components fit together in layered architecture and the interactions between them. To produce such a framework, this thesis first investigates the definition of a Grid-workflow architecture and mapping Grid functionality to workflow nodes, focusing on striking a balance between performance, usability and the Grid functionality supported. Next, it presents an examination of framework extensions for supporting various forms of Grid heterogeneity, essential for ii VO based collaboration. Given the complex nature of Grid technologies, the work presented here investigates abstracting Grid based workflows through high-level definitions and resolution using semantic technologies. Finally, this thesis presents a way to resolves abstract Grid workflows using semantic technologies and intelligent, autonomous agents. The frameworks presented in this thesis are tested and evaluated within the context of domain-based case studies defined in the SIMDAT, BRIDGE and ARGUGRID EU funded research projects.

Attentional biases in social anxiety: an investigation using the inattentional blindness paradigm

Lee, Han-Joo 05 November 2009 (has links)
Social anxiety disorder is the third most common mental disorder with the lifetime prevalence rate of 13.3% in the US population. Typically, it causes significant impairment in a wide range of functioning and follows a chronic, unremitting course if untreated. Over the past two decades, there has been a dramatic increase in clinical research aimed at examining underlying mechanisms maintaining social anxiety. One line of research has investigated attentional biases in social anxiety, using various cognitive experiment paradigms, including the emotional Stroop and the modified dotprobe tasks. However, overall findings are equivocal about the nature of attentional biases in social anxiety and several methodological problems limit the interpretability of the data. The present study examined attentional biases associated with social anxiety using a new research paradigm in the field of anxiety disorders: the inattentional blindness paradigm. This paradigm presents a social cue in the absence of the subjects’ expectation while they are engaged in a cognitively demanding task, thereby enabling the more purely attentional aspect of information processing to be examined reducing the influence of potential response biases or effortful strategies. Two independent experiments were conducted using nonclinical student samples consisting of individuals high in social anxiety (HSAs) versus individuals low in social anxiety (LSAs) based on the static and sustained inattentional blindness tasks. Overall, results revealed that HSAs were more likely to detect or identify a socially-threatening cue, relative to LSAs; whereas LSAs were more likely to detect or identify a non-threatening social cue, relative to HSAs. These findings were observed only in the presence of a bogus-speech manipulation. These data suggest the promising utility of the inattentional blindness paradigm in investigating attentional biases in social anxiety and perhaps other psychopathological conditions. Theoretical and clinical implications are discussed. / text

To Lead or to Follow? : A case study of an internationalization process

Kaukonen, Ulla, Haapanen, Heta-Liisa January 2008 (has links)
<p>This Bachelor thesis studies the internationalization strategy of a Finnish label stock company, UPM Raflatac, in China during the late 1990’s. The purpose of this descriptive study is to facilitate the understanding of companies’ internationalization processes. This was done by studying UPM Raflatac’s internationalization strategy’s connection to the internationalization theories of the Uppsala model and the eclectic paradigm. The findings were established by presenting an Internet based questionnaire for the employees of the company. The results showed that the company did not have a country specific strategy and that the resemblance to the reference material was therefore limited.</p>

Studies of art subjects in training future specialists at a college: the context of educational paradigm shift / Meno dalykų studijos rengiant būsimus specialistus kolegijoje: edukacinių paradigmų virsmo kontekstas

Malcienė, Zita 27 January 2011 (has links)
The shift of educational paradigm, analyzed in the dissertation, is determined by the cultural changes, globalization and the reality of vocational training in independent Lithuania, which are inherent for the present epoch. At an institution of higher education this context is manifested by the modernization of studies, which is qualified as a strategy of educational paradigm shift and analyzed in terms of the peculiarities of vocational training theory and practice. The latter two factors are revealed by exploring the peculiarities and relations of the theory and practice of vocational training. The practical purposefulness of studies is emphasized in college training of future specialists. In the dissertation it is qualified as a strategy of the modernization of studies. The peculiarities of vocational training, teaching of art subjects and art education are analyzed with regard to the shift of educational paradigms. It appears that in the modernization of studies it is relevant to withdraw from conventional teaching, which is oriented towards narrow subject aims, and switch to profession-oriented art education. Therefore, profession-oriented art education is presented as a strategy of modernizing art subject studies. Theoretical models of a future specialist’s vocational training, traditional teaching of a subject (music) and contemporary art (music) education are presented, which cover the areas of subject studies, environment, scope of roles and activities.
