The respondents expressed an opinion on the data collected, about itsmeaning, significance and possible uses. More broadly the results obtained in twosteps point to the undeniable importance of institutional repositories in thecommunication process of scientific production of an institution of higher education.

Scholarly communication of all types is changing dramatically with the introduction of electronic technologies. This new environment means that standalone print publishing risks being left behind, and as many STM journals acquired or launched by commercial publishers have been subject to dramatic price rises in the last few years, there has been much talk of ways to by-pass commercial publishers. The scholarly publishing market is fertile ground for innovation and there has been a lack of objective research regarding the UK university press. Despite the many changes that have occurred in the scholarly publishing industry in recent years, university presses in the UK that have not been in the forefront of innovation have remained minor players. The research focused on the university press, it's current situation and it's role in the electronic future. The research included: case studies that were conducted at both UK and USA university presses, along with the corresponding libraries, a questionnaire which was sent to academic authors that had published with both a university press and a commercial publishing house, and both qualitative and quantitative questionnaires sent to all operating UK university press directors. The thesis argues that university presses (in particular the smaller presses), as not for-profit organisations, are in a prime position to increase their power in the scholarly publishing system and can make changes to provide valued services to the Higher Education Community. Findings show that university presses, both in the USA as well as the UK, have faced, and continue to face change. Lack of funding and HEI support continues to make the traditional publishing role of the university presses difficult, and, in many cases, has caused the closure and sale of university presses in the UK. The university press continues to play an important role, and will continue to do so in the near future. However, in order for smaller university presses in the UK to remain sustainable, they must continue to adapt to, and take advantage of, change, recognise the value they add to the scholarly communication system and not rely on others to improve their situation. They cannot remain static in a changing environment. Through the work with university presses three potential business plans are proposed for a UK organisation of university presses, along with two business models to help the presses adapt to the changing environment and continue to play a role that is required by the HEI. Based on the results and conclusions of the research recommendations are made to stakeholders and ideas for further research are identified.

Parallel to the Open Source Software movement, there is an increased demand and need for free, open access to information resources. The Open Access initiative is characterized by two strategies: namely the promotion of self-archiving or, alternatively, publishing of research articles in open-access journals. The purpose of an Institutional Repository (IR) is to provide a suitable archival environment for the self-archiving of digital items. This study provides a clear understanding of the issues surrounding the implementation of an IR. Issues discussed include software selection, as well as the development, implementation and marketing of an IR. An equally important issue is individual skills development. Attention is given to the development of the policies that are required by an organization and its main stakeholders. These policies form an essential part of the development of an information system. Issues such as acceptance, usage, population, and management of the repository are reported on. The actual work that was done at the CSIR is used as a case study. The implementation process at the CSIR and the subsequent lessons learnt are used to highlight some of problems experienced and how these problems were solved. Issues that still need investigation, e.g. long-term preservation, are discussed. / Dissertation (MPhil)--University of Pretoria, 2008. / Informatics / unrestricted

Glaciation is considered one of the main natural processes that can have a significant impact on the long term performance of DGRs. The northern part of the American continent has been subjected to a series of strong glaciation and deglaciation events over the past million years. Glacial cycles cause loading and unloading, temperature changes and hydraulic head changes at the ground surface. These changes can be classified as transient boundary conditions. It is widely accepted that the periodic pattern of past glacial cycles during the Late Quaternary period are resultant of the Earth’s orbital geometry changes that is expected to continue in the future. Therefore, from the safety perspective of DGRs, such probable events need to be taken into account. The objective of this thesis is to develop a numerical model to investigate the thermo-hydro-mechanical-chemical (THMC) coupled processes that have resulted from long term past and future climate changes and glaciation cycles on a proposed DGR in sedimentary rocks in southern Ontario. The first application is done on a large geological cross section that includes the entire Michigan basin by using a hydro-mechanical (HM) coupled process. The results are compared with field data of anomalous pore water pressures from deep boreholes in sedimentary rocks of southern Ontario. In this work. The modeling results seem to support the hypothesis that at least the underpressures in the Ordovician formation could be partially attributed to past glaciation. The second application is made on site conditions by using the THMC model. The results for the pore water pressure, tracer profiles, permafrost depth and effective stress profile are compared with the available field data, the results show that the solute transport in the natural limestone and shale barrier formations is controlled by diffusion, which provide evidence that the main mechanism of transport at depth is diffusion-dominant. The third application is made on site conditions to determine the effect of underground changes in DGRs due to DGR construction. The results show that future glaciation loads will induce larger increases in effective stresses on the shaft. Furthermore, it is found that hypothetical nuclide transport in a failed shaft can be controlled by diffusion and advection. The simulation results show that the solute transported in a failed shaft can reach the shallow bedrock groundwater zone. These results might imply that a failed shaft will substantially lose its effectiveness as a barrier. The fourth application is proposed to investigate the geochemical evolution of sedimentary host rock in a near field scale. In this part, a new thermo-hydro-mechanical-geochemical simulator (COMSOL-PHREEQC) is developed. It is anticipated that there will be a geochemical reaction within the host rock that results from interaction with the water enriched with the CO2 generated by nuclear waste.

Na atualidade, os acervos arquivísticos são híbridos, isto é, são compostos por documentos nascidos digitais, digitais e analógicos. Isso exige das instituições a otimização de seus serviços, ainda mais no que se refere ao atendimento ao usuário que almeja ter satisfeitas suas necessidades informacionais de maneira fácil, rápida e segura. Nesse cenário, o objetivo deste trabalho é analisar o conjunto de atributos essenciais para a implantação de Repositórios Arquivísticos Digitais Confiáveis (RDC-Arq) e a vinculação do arquivista como membro integrante de uma equipe de trabalho na orientação dos requisitos com ênfase ao acesso à informação. Optou-se como procedimento metodológico pelo estudo teórico fundamentado nos princípios da Arquivologia. A etapa exploratória é realizada a partir da análise da Resolução 39 do CONARQ (Diretrizes para a implementação de Repositórios Arquivísticos Digitais Confiáveis RDC-Arq) e da ISO 16363:2012 (Space data and information transfer systems -- Audit and certification of trustworthy digital repositories) que fazem recomendações técnicas para serem utilizadas como base para que repositórios digitais sejam certificados confiáveis ou que possibilitem a medição da confiabilidad...

Currently, the archival collections are hybrids, ie they are composed of documents that were originally digital, converted to digital, and analog. This requires that the institutions optimize their services, especially as regards to service to the user who aims to have his / her information needs satisfied easily, quickly and safely. In this scenario, the objective of this study is to analyze the set of essential attributes for the deployment of Trusted Digital Archival Repositories (TDARs) and the linking of the archivist as a member of a work team in guiding the requirements with emphasis on access to information. The methodological procedure was chosen by theoretical study grounded on the principles of Archivology. The exploratory stage is carried out from the analysis of Resolution 39 of CONARQ (Guidelines for the implementation of Trusted Digital Archival Repositories TDARs) and ISO 16363: 2012 (Space data and information transfer systems - Audit and certification of trustworthy digital repositories) that make technical recommendations used as a basis for digital repositories being certified as reliable or allow the measurement of repository reliability. The results present the archivist's actions for access to archival docume... (Complete abstract click electronic access below) / Doutor

Altmetrics derived from Twitter have potential benefits for institutional repository (IR) stakeholders (faculty, students, administrators, and academic libraries) when metrics aggregators (Altmetric, Plum Analytics) are integrated with IRs. There is limited research on tweets mentioning works in IRs and how the results impact IR stakeholders, specifically libraries. In order to address this gap in the literature, the author conducted a content analysis of tweets tracked by a metrics aggregator (Plum X Metrics) in a Digital Commons IR. The study found that the majority of tweets were neutral in attitude, intended for a general audience, included no hashtags, and were written by users unaffiliated with the works. The results are similar to findings from other studies, including low numbers of tweeted works, high numbers of tweets neutral in attitude, and evidence of self-tweets. The discussion addresses these results in relation to the value of tweets and suggested improvements to Twitter metrics based on IR stakeholders’ needs.

Artistic research is a relatively new and understudied topic in scholarly communication within Library and information science. This knowledge deficit, combined with ill-fitting systems and categories, maintains the status of artistic research as something mysterious and different. As a result, knowledge produced through artistic research may not be justly represented in the academic infrastructures, and not be made available with the same integrity as traditional research output. The aim of this study is to map the publishing landscape of artistic research in Sweden and to describe how outputs of artistic research relate to current academic infrastructures. An inductive analysis of the units of academic output listed by the researchers themselves as publications of research shows how they are represented in, and outside of, the archiving systems. The analysis is supported by document theory, Kuhn's theory of scientific paradigms, and the classification theory of Bowker and Star. Findings suggest that publishing practices on the level of each project are influenced by institutional affiliation. Researchers are forced to a trade-off between statistical visibility in institutional repositories and coherent content visualization in extra-institutional channels. The institutional infrastructures designed for traditional output lack guidance for artistic output, which results in in consistency in registration, poor quality of representation, and inconsistent metadata. Channels outside of the institution lack discoverability and statistical visibility.

The dissertation is devoted to analysis of current practice and trends in providing repositories of electronic theses and dissertation (ETDs) in terms of their management, searching and dissemination. The first part presents terminology and the current state of access to ETDs in Czech and foreign repositories and includes results of a survey of the state of access to ETDs in the Czech Republic which was completed in 2014 by all public universities. In the second part, a metadata standard is presented, particularly the possibility of mapping EVSKP-MS metadata elements to other metadata formats and utilization within the OAI-PMH protocol. The issue of access to ETDs is dealt with further in terms of metrics for an evaluation of usage of distributed ETDs. Searching for ETDs is also described in case studies as are recommendations for public tenders for a discovery service and for creating an ETD metadata search server and an associated user interface with faceted search. The final part of the thesis focuses on the issue of plagiarism. This incorporates a presentation and analysis of the most important plagiarism detection systems and a case study of the development of the portal Validátor VŠE to provide access to results of document analysis.
