The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
Language Change and SA-OT: The case of sentential negation
No full textSimulated Annealing for Optimality Theory (SA-OT) updates Optimality Theory by adding a model of performance to a theory of linguistic competence. Our aim is to show that SA-OT can contribute to language change simulations. Performance "errors" are considered to be one of the causes of variation and change. We have chosen to model the evolution of sentential negation (SN). The descriptive background adopts Jespersen's Cycle, according to which the evolution of sentential negation follows three main stages (1. pre-verbal, 2. discontinuous, and 3. post-verbal). Therefore, we advance a novel model for SN, based on SA-OT. It reproduces the three pure and the two observed mixed stages, whereas it correctly predicts the lack of an intermediate stage between 3 and 1. The success of the approach corroborates the computational, performance-based approach to the data. Finally, we employ the iterated learning paradigm to reproduce historical changes in a "simulated corpus study". This enterprise turns out to be more difficult than one would naively believe.Appeared open access as: Computational Linguistics in the Netherlands Journal (CLIN), vol. 1 (2011), pp. 21-40, and is available at http://www.clinjournal.org/sites/default/files/Lopopolo.pdfA.

Robust automated servicing of passenger train fluids
No full textTo meet increased capacity demands of passengers in the rail industry, a robotic and autonomous system that services the fluids on passenger rail vehicles was proposed. A hierarchical task analysis of fluid servicing processes was conducted and human and system errors were highlighted. This information, along with opinions of technical managers and staff were inputted into a quality function deployment matrix to make a design specification; from this specification two concepts were proposed. Both concepts are viable but modification to rail vehicles is required. A proof of concept will next be developed to begin a path to a commercial product.Brunel University London would like to acknowledge RSSB and RRUKA for funding this project and providing contact with key rail stakeholders
Stakeholder research CoVE Water SA: CoVE Water SA the umbrella for all stakeholders
No full textThe water and sanitation sector faces well-documented issues that are challenging to address, leading to the establishment of the Platform of Vocational Excellence (PoVE) Water. This platform brings together five regional Centers of Vocational Excellence (CoVE) Water in Europe and South Africa to ensure high-quality skills and competencies in the water sector. These CoVEs facilitate collaboration among stakeholders, enabling the development of vocational education and training programs to increase awareness, responsiveness to industry needs, and address sector challenges. A few months ago, CoVE Water SA was established in South Africa to achieve the previously mentioned goals. Therefore, it is important that the following research question is answered in this initial set-up phase: What actions need to be taken to enhance the effectiveness of the CoVE Water SA? To answer this research question, several important stakeholders were interviewed. Subsequently, the interviews were analysed thematically in order to extract the most important themes and quotes, PI grids were created to assess power and interest dynamics among stakeholders, and a Social Network Analysis was conducted to understand the CoVE Water SA network and potential clusters.The research findings have unveiled key aspects for enhancing the effectiveness of CoVE Water SA. The current network in the water sector has a low density, implying that many collaborations are lacking. This leads to a high degree of interdependence within the network, resulting in a non dynamic system. The lack of collaborations, such as connections with TVET colleges, schools, farmers and local communities, results in a lack of knowledge, funding and connection to the labour market. Governmental stakeholders, like DWS, EWSeta, and BGCMA, have been identified as influential players with extensive networks and important resources, Local Authorities and Research Organizations also play important roles. Universities exhibit substantial international links, making them crucial contributors. These stakeholders have the potential to provide knowledge, collaboration, and power. These are valuable insights for CoVE Water SA, fostering network growth and effectiveness in the water sector. Furthermore, six key themes have been derived from the conducted interviews, addressing the needs of stakeholders and where CoVE can make a valuable contribution. These themes include raising awareness, reducing the skills gap in the water sector, fostering international collaborations, mitigating the labour shortage in the water sector, improving education material and establishing desired collaborations. For each theme, the interviewed stakeholders have presented their views and numerous suggestions on how CoVE Water SA can assist in addressing these issues. Additionally, stakeholders have also mentioned possible failures of CoVE Water SA, which can aid in preventing any shortcomings of the platform. Furthermore, stakeholders mentioned ongoing initiatives related to the six themes, through which they can contribute to the platform. From the Thematic Analysis, PI Grids and the SNA, a set of actions have emerged that are essential for enhancing the effectiveness of CoVE Water SA. These actions revolve around expanding and enhancing the network, organising activities and contributing to educational improvement. In terms of broadening and strengthening the network, the platform should focus on enhancing the collaborations among educational groups, building stronger relations with international institutions in Europe and Africa, involving TVETs and schools within the water network, improving stakeholder involvement and encouraging the involvement of Local Communities to increase awareness and knowledge about water issues. Furthermore, CoVE Water SA should play a role in organising activities to raise awareness of Water Resource Management. Additionally, it should assist in improving curricula, supporting students’ preparation for the workforce and making the education more practical instead of only theoretical. CoVE Water SA should also provide training and learning resources as well as comprehensive courses.However, this study recognizes several limitations that should be considered in future research and when implementing recommendations for CoVE Water SA. These limitations encompass factors like a limited scope due to resource and time constraints, minimal varied interviewee responses, and potential biases in responses. Addressing these limitations will be crucial in guiding future research and actions for CoVE Water SA.CEGM3000Civil Engineerin

Effect of influent nutrient ratios and hydraulic retention time (HRT) on simultaneous phosphorus and nitrogen removal in a two-sludge sequencing batch reactor process
No full textA laboratory-scale anaerobic–anoxic/nitrification sequencing batch reactor (A2N-
SBR) fed with domestic wastewater was operated to examine the effect of varying
ratios of influent COD/P, COD/TN and TN/P on the nutrient removal. With the
increased COD/P, the phosphorus removals exhibited an upward trend. The influent
TN/P ratios had a positive linear correlation with the phosphorus removal
efficiencies, mainly because nitrates act as electron acceptors for the
phosphorus uptake in the A2N-SBR. Moreover, it was found that lower COD/TN
ratio, e.g. 3.5, did not significantly weaken the phosphorus removal, though the
nitrogen removal first decreased greatly. The optimal phosphorus and nitrogen
removals of 94% and 91%, respectively were achieved with influent COD/P and COD/
TN ratios of 19.9 and 9.9, respectively. Additionally, a real-time control
strategy for A2N-SBR can be undertaken based on some characteristic points of
pH, redox potential (ORP) and dissolved oxygen (DO) profiles in order to obtain
the optimum hydraulic retention time (HRT) and improve the operating reliabili
Historický vývoj a charakteristika rozvojovej pomoci
No full textV príspevku sa autor zaoberá vývojom povojnových rozvojových teórií, ktorých podstatou je skúmanie príčin, dôsledkov zaostalosti krajín rozvojového sveta a vzniku ekonomických a spoločenských disparít medzi jednotlivými regiónmi sveta. Z chronologického hľadiska sa autor v príspevku venuje relevantným historickým aspektom, ktoré ovplyvnili vznik rozvojovej pomoci vo forme ako ju poznáme v súčasnosti. Východiskovou teóriou zahraničnej rozvojovej pomoci sa stala teória „Začarovaného kruhu chudoby“ a z nej vychádzajú mnohí autori, ktorí hľadajú východiská zo zaostalosti a prehlbovania sa rozdielov medzi vyspelými a zaostalými krajinami sveta. Jednotlivé regióny sú špecifické určitými charakteristikami, ktoré autor rozoberá v poslednej časti príspevku.rozvojové teórie, rozvojová pomoc, zahraničná pomoc, začarovaný kruh
A novel duplication polymorphism in the FANCA promoter and its association with breast and ovarian cancer
No full textThe FANCA gene is one of the genes in which mutations lead to Fanconi anaemia, a rare autosomal recessive disorder characterised by congenital abnormalities, bone marrow failure, and predisposition to malignancy. FANCA is also a potential breast and ovarian cancer susceptibility gene. A novel allele was identified which has a tandem duplication of a 13 base pair sequence in the promoter region.Methods:
We screened germline DNA from 352 breast cancer patients, 390 ovarian cancer patients and 256 normal controls to determine if the presence of either of these two alleles was associated with an increased risk of breast or ovarian cancer.Results:
The duplication allele had a frequency of 0.34 in the normal controls. There was a non-significant decrease in the frequency of the duplication allele in breast cancer patients. The frequency of the duplication allele was significantly decreased in ovarian cancer patients. However, when malignant and benign tumours were considered separately, the decrease was only significant in benign tumours.Conclusion:
The allele with the tandem duplication does not appear to modify breast cancer risk but may act as a low penetrance protective allele for ovarian cancer

The means and the end. Russell's political philosophy
No full textThe author shows how the apparent lack of connections between B. Russell's philosophy and his
political thought is a consequence of the external relations doctrine. Deprived of metaphysics man
becomes an orphan, and this leads Russell to a singular conception of man and power based on
individual rather than on collective and social values. These particularities in Russell's political
thought explain in certain respects the very clear division of his work into philosophical writings
and political writings.L'auteur montre comment ce qui apparaît comme absence de liens entre la philosophie et la
pensée politique de Russell est une conséquence de la doctrine des relations externes. Celle-ci
rend l'homme orphelin de la métaphysique, et conduit Russell à une conception singulière de
l'homme et du pouvoir fondée sur des valeurs individuelles plutôt que collectives ou sociales.
Ces particularités de sa pensée politique expliquent à certains égards la division très apparente
de l'oeuvre de Russell en écrits philosophiques et en écrits politiques
