In modern organisations, the effective use of information and knowledge is a prerequisite for sustaining competitive advantage. To support this, considerable work has been undertaken by both academia and industry to improve the representation, organisation and access of information across and between organisations. This improved information and communication management has had a positive impact on business processes, improved decision making and – importantly – increased levels of innovation. However, one area that has received less attention is personal information such as logbooks, maintained by a majority of engineers. Many of these logbooks could contain significant amount of design information and knowledge which is not recorded elsewhere, such as design rationale and records of alternatives considered. Indeed, much of what we know about the work of historically important engineers and scientists such as Leonardo da Vinci (1452-1519) has come from their personal collections of notes. Despite this, logbooks are rarely formally managed, with the content usually only available to the authoring engineer. It is arguable that such potentially valuable information should be more easily accessible to the individual and wider organisation, where it could be of benefit as a personal productivity aid, a design record and also for intellectual property and audit/traceability purposes. It follows that there is a need to create improved methods for managing logbook content, which is the challenge that this research addresses. This research first seeks to establish the reasons for the stubborn persistence of paper logbooks as such a common feature of engineering work, despite almost every other aspect being undertaken in the digital domain. Various studies are undertaken, revealing that logbooks are used for a wide range of purposes, such as the critical role of ‘mediating’ between various information sources. The requirements arising from these studies are used together with a review of existing e-logbook technologies to produce a comprehensive requirement specification for an engineering electronic-logbook. At its core is a novel information management strategy based combination of templates to pre-structure entries and a lightweight information classification schema to structure the information. They key features of the specification are the ability for logbook information to be searched, shared and integrated with other information systems, whilst retaining important characteristics of paper logbooks (such as sketching support). The contributions of this thesis are the fundamental understanding of logbook use and content, together with a comprehensive specification for an engineering e-logbook to improve logbook information management for both the individual and wider organisation.

<p>With timeliness and efficiency being critical in the aviation maintenance industry, the need has been growing for smart technological solutions that help in optimizing and streamlining the different underlying tasks. One such task is the technical documentation of the performed maintenance operations. Instead of paper-based documentation, voice tools that transcribe spoken logbook entries allow technicians to document their work right away in a hands-free and time efficient manner. However, an accurate automatic speech recognition (ASR) model requires large training corpora, which are lacking in the domain of aviation maintenance. In addition, ASR models which are trained on huge corpora in standard English perform poorly in such a technical domain with non-standard terminology. Hence, this thesis investigates the extent to which fine-tuning an ASR model, pre-trained on standard English corpora, on limited in-domain data improves its recognition performance in the technical domain of aviation maintenance. The thesis presents a case study on one such pre-trained ASR model, wav2vec 2.0. Results show that fine-tuning the model on a limited anonymized dataset of maintenance logbook entries brings about a significant reduction in its error rates when tested on not only an anonymized in-domain dataset, but also a non-anonymized one. This suggests that any available aviation maintenance logbooks, even if anonymized for privacy, can be used to fine-tune general-purpose ASR models and enhance their in-domain performance. Lastly, an analysis on the influence of voice characteristics on model performance stresses the need for balanced datasets representative of the population of aviation maintenance technicians.</p>

Roberto da Sanseverino went on a pilgrimage to the Holy Land in 1458. He travelled from Venice to Jaffa on a galley and made his return, from Acre to Ancona, on a three-masted sailing ship. During both voyages he kept very accurate logs of distances, courses and wind directions. He described the sails employed for different modes of sailing and other activities pertaining to the safe operation of the vessels. These logs are contained in Sanseverino's diary of his pilgrimage and are an essential part of an original manuscript kept at the University of Bologna. This diary is the first documentation, and the only one known to exist up to this time, which presents a complete description of the methods employed by medieval shipmasters to navigate and handle their ships overlong voyages. The accuracy and reliability of the numeric data and of the other facts contained in the logs are such that, among other unusual findings, they make it possible to deter-mine the length of the Venetian sea mile, the angles of tack of medieval ships to windward and the speeds attainable under various conditions of sailing. Other original descriptions encompass the handling of ships in anchorages and some of the technical considerations that were essential to ensure ship seaworthiness under different conditions of cargo. Further reflections on all these data make it possible to arrive at certain conclusions about the economic constraints of sea ventures in different seasons of the year.

Para isso, selecionamos como l?cus de pesquisa uma escola p?blica da Rede Municipal de Belo Horizonte. Optamos pela metodologia de pesquisa predominantemente qualitativa. Como instrumentos de coleta de dados, foram utilizados a an?lise de documentos e as entrevistas semiestruturadas. Os documentos que nos serviram para as an?lises foram os di?rios de bordo ? livro de ocorr?ncia ? produzidos pela escola entre os meses de fevereiro e novembro de 2016, referentes ?s sete (7) turmas dos anos finais do Ensino Fundamental, oitavos (8?) e nonos (9?) anos. Colaboraram com a pesquisa: dois professores, selecionados a partir da an?lise dos documentos, os dois gestores da escola e os dois coordenadores do terceiro ciclo. A pesquisa justifica-se pela necessidade do debate acerca da viol?ncia e de como o tema tornou-se emergente nos diversos campos sociais, sobremaneira na escola. As mudan?as que perpassam a sociedade trouxeram ? institui??o escolar novas atribui??es, ocasionadas, entre outros fatores, pela diversidade dos sujeitos que a ela t?m acesso. Neste aspecto, este estudo apresenta uma reflex?o sobre os significados que admite o termo viol?ncia, discutidos, no segundo cap?tulo da disserta??o, sob o aporte te?rico de estudiosos como Hanna Arendt, Marilena Chaui, Slavoj Zizec, Vera Candau e outros. Ao analisar as ocorr?ncias registradas nos di?rios de bordo e as implica??es desses eventos no trabalho docente, tais conceitos s?o retomados no sentido de ampliar nosso entendimento. Ressaltamos que, a partir das an?lises da parte objetiva, constantes nos formul?rios dos di?rios de bordo, foram encontrados dois mil e seiscentos e doze (2.612) registros, nos quais constavam mais de seis mil (6.000) ocorr?ncias, que, em sua maioria, referem-se a situa??es que, a princ?pio, podem ser entendidas como indisciplinares. A leitura e a an?lise dos mil seiscentos e dois (1.602) relatos descritivos possibilitaram a constata??o da ambiguidade no uso do termo brincadeira, que deixa subentendidos comportamentos que envolvem pequenos furtos de materiais escolares e outros objetos e as agress?es f?sicas e verbais, viol?ncias manifestas no cotidiano escolar. Como repercuss?es da viol?ncia no trabalho docente, foram identificadas pela pesquisa: a intensifica??o e a autointensifica??o do trabalho docente, analisadas ? luz dos estudos de Assun??o (2005), Duarte e Oliveira (2014), Garcia e Anadon (2009), Oliveira et al. (2004) e Noronha (2008). O adoecimento dos docentes e o baixo rendimento acad?mico dos estudantes tamb?m s?o apontados como repercuss?es da viol?ncia. / Disserta??o (Mestrado Profissional) ?

To do so, a public school of the city of Belo Horizonte has been chosen as locus of research.We opted for a predominantly qualitative research methodology. As data collection instruments were used document review and semi-structured interviews. The documents used for the analyses were thelog-book of occurrence produced by the school staff between the months of February and November 2016, relating to seven (7) grades of the final years of primary school, eighth (8) and ninth (9) grades.Collaborated with the research: two teachers, selected from the analysis of the documents, the two managers of the school, Principal and the vice one,two coordinators of Middle School.The research is justified by the need for a debate on violence and how the subject became emerging in various social fields, particularly at school. The changes that have taken place in the nowadays society brought new tasks to schools,caused, among other factors, by the diversity ofthe attendees that have access to schools. In this respect,this studypresents a reflection upon the meanings that the term violence has, discussed, in the second chapter of the dissertation, under the theoretical contribution of scholarssuch as Hannah Arendt, Marilena Chaui,Slavoj Zizec, Vera Candau and others. To analyze theoccurrences recorded in logbooks and the implications of these events on theacher?swork, such concepts areincluded in order to broaden our understanding. We emphasizethat,from the analysis of the objective part, in forms of logbooks,were found 2612 (2,612) records, which contained more than 6000 (6,000), which, mostly, refer to situations regarded as Student indiscipline. The reading and analysis of 1602 (1,602) descriptive reports enabled the finding of ambiguity in the use of the term joke and it allows the interpretation that such Jokes really refer to behaviors involving theft of school materials and other objects , physical assaults, verbal agression and everyday violence. As repercussions of violence at work, were identified in the survey: the intensification and the self intensification of teacher?s work analysed in thelight of the studies of Asunci?n (2005), Duarte and Oliveira(2014), Garcia and Anadon (2009), Oliveira et al. (2004) and Noronha ( 2008). Episodes of illnesses in teachers and the students' academic underachievement are also pointed out as repercussions of violence.

The Gulf of Mexico commercial reef fish fishery has experienced significant management changes and disturbance in recent years, including transitioning two major fisheries from a traditional open access system into a limited entry individual fishing quota (IFQ) system in 2007 and 2010. Also in 2010, the Deepwater Horizon oil spill (DWH) released an estimated 4.9 million barrels of oil into the Gulf (~206 million U.S. gallons), and is still the largest U.S. environmental disaster to date. Emergency fishing closures initiated shortly after the oil spill began were successful in keeping tainted seafood from reaching markets. However, effects of DWH closures on fisher decision making, fishery productivity, and distribution of fishing effort all remain poorly understood. Understanding the range and magnitude of fishers’ responses to perturbations — including regulatory change and human-induced environmental disasters — is critical for designing effective management and disaster response policies that can meet biological, ecological, economic, social, and sustainability objectives. This work characterized the spatial and temporal patterns of productivity and fishing effort for the Gulf of Mexico (GoM) commercial reef fish fishery. Patterns of productivity and effort distribution were used to examine the response of fishers to management change and large-scale disturbance, namely the DWH fishing closures. Fisheries-dependent logbook trip reports were used to quantify revenue and catch-per-unit-effort (CPUE) patterns from 2000-2014. Novel to fisheries work in the GoM, complementary vessel monitoring systems (VMS) satellite tracking data were used to quantify high-resolution spatial distribution patterns over time, relative to the DWH fishing closures. A general linear modeling (GLM) approach was also used to examine which variables may have contributed to resilience of fishers after DWH closures. Results suggested that this fishery was largely resilient to the DWH fishing closures in 2010, although exact outcomes varied by region. Overall fleet-level productivity steadily increased over time, but regional patterns were based on major species in catch. Productivity in the western GoM was consistently highest over time, and trips in the west and central GoM were dominated by Red snapper (Lutjanus campechanus) and Vermilion snapper (Rhomboplites aurorubens). Trips in the east were dominated by Red grouper (Epinephelus morio) and Gag grouper (Mycteroperca microlepis). Shifts in spatial distribution to new productive fishing grounds or reduced competition via fewer vessels or trips may explain the increases in productivity observed over the study period. Consolidation in the fleet was apparent, with fewer individual vessels and fewer total trips over time. However, the rate of vessel drop out after DWH (5%) was far below the annual background attrition rate of ~14-20%. Relative productivity patterns inside vs. outside the boundaries of fishing closures did not change over time, and there were even some increases in productivity observed during and after DWH in the eastern GoM. Yet, vessels that dropped out after DWH were concentrated in the north-central and eastern GoM. Distribution of fishing grounds before and after DWH were highly similar, and there were increases in effort along the outer West Florida Shelf. Variability in revenue and CPUE, CPUE magnitude, and magnitude of grouper landings were significant predictors of dropping out of the fishery in the GLMs. Synergies with the Red snapper or Grouper-Tilefish IFQs may have “primed” the fishery for resilience by eliminating inconsistent or marginal fishers before the oil spill, and may further explain some of the spatially varying patterns of productivity and attrition after 2010. Resilience was likely also enhanced by the more than $2 billion in emergency compensation payments made to captains, crew, and vessel owners for lost fishing income and assistance with oil remediation efforts. This work stands to make a significant contribution to our understanding of how the DWH oil spill impacted fisheries and communities in the GoM. The results add to a growing body of literature suggesting that the acute population- and ecosystem-level impacts of the DWH oil spill were not as strong or severe as initially anticipated. This work also stands to make contributions to the broader understanding of how this fishery has performed in the wake of recent management change and major environmental disturbance.

The research s evolution is told on a Benjaminian perspective, where experience is maximally contextualized, in an attempt to embrace varied points of view about all involved actors and questioning the consequences of the mediation presented preferably in groups. The Collective Pedagogical Working Hours (CPWH), thought as the only possible suitable moment for a mediation site between coordinator and group, will be contextualized starting from the reading of the logbooks written by the professionals and will be the framing axis of the pedagogical coordination s mediation, as well as a privileged tool to follow up and assess the propositions put forward to the group. From the dialogues that emerged among texts written by the professionals and the coordinator s feedbacks an interlocution gets started, where the other is seen as responsible and collaborator in aesthetic experience and pleasure choices, beyond the awareness of popularized Culture, searching for an Aesthetics of fracture recommended by Algirdas Julien Greimas. The presentation of cultural objects and device, always based on Ethic conjunctures and the Theory of Communicative Actions by Jurgen Habermas, together with Van Dijk s Mental Models, provide the elements for a careful analysis of a teacher s written topics. This thesis is presented in five chapters that look for reconstructing the pedagogical coordinator s path to mediate and valorize cultural objetcs and device to professionals under his responsibility, making use of a narrative of his initial procedures and ending up in a description of what he understands as Cultural Pedagogy / Esta pesquisa realizada em duas escolas municipais de uma cidade da Grande São Paulo utiliza-se da pesquisa colaborativa, procurando apresentar a possibilidade da coordenação pedagógica lançar mão de mediações de objetos e dispositivos culturais para o desenvolvimento de uma Pedagogia Cultural amparada nas teorias de Jerome Bruner. O desenvolvimento da pesquisa é narrado numa perspectiva benjaminiana, em que a experiência é contextualizada ao máximo, procurando abarcar os diversos pontos de vista dos atores envolvidos e problematizando as consequências das mediações apresentadas preferencialmente em grupo. O Horário de Trabalho Pedagógico Coletivo (HTPC), pensado como único momento possível de se prestar como espaço de mediação do coordenador para o grupo, será contextualizado a partir das leituras dos diários de bordo escritos pelas profissionais e será o eixo estruturante das intervenções da coordenação pedagógica, bem como o instrumento privilegiado de acompanhamento e avaliação das proposições lançadas ao grupo. Dos diálogos que surgem entre as escritas das profissionais e as devolutivas do coordenador abre-se uma interlocução em que o outro é visto como responsável e colaborador nas escolhas de fruição e vivência estética para além das percepções de uma Cultura massificada, buscando a fratura estética preconizada por Algirdas Julien Greimas. A apresentação dos objetos e dispositivos culturais sempre embasada em pressupostos Éticos e da Teoria da Ação Comunicativa de Jurgen Habermas, juntamente com as ideias de Modelos Mentais de Van Dijk, nos fornecem elementos para uma análise cuidadosa do material escrito por uma professora. A tese apresenta-se em cinco capítulos que buscam reconstruir o caminho trilhado pelo coordenador pedagógico na mediação e valorização dos objetos e dispositivos culturais para as profissionais que estiveram sob sua responsabilidade, fazendo uso de uma narrativa de seus procedimentos iniciais e terminando com a descrição do que compreende ser a Pedagogia Cultural
