The purpose of this dissertation was to use the technology of text mining and topic modeling to explore unobserved themes of medical case reports that involve medical imaging. Case reports have a valuable place in medical research because they provide educational benefits, offer evidence, and encourage discussions. Their form has evolved throughout the years, but they have remained a key staple in providing important information to the medical communities around the world with educational context and illuminating visuals. Examining medical case reports that have been published throughout the years on multiple medical subjects can be challenging, therefore text mining and topic modeling methods were used to analyze a large set of abstracts from medical case reports involving radiology. The total number of abstracts used for the data analysis was 68,845 that were published between the years 1975 to 2022. The findings indicate that text mining and topic modeling can offer a unique and reproducible approach to examine a large quantity of abstracts for theme analysis.

This study of the wilderness visitors to the Okefenokee National Wildlife Refuge, Georgia sought to better define the dimensions of the lived wilderness experience, and the modes in which it is experienced; to understand the dynamics of the wilderness experience and how the wilderness experience changes across time; and to examine the relationship between the wilderness experience and ideal leisure. Because of people's apparent difficulty in accurately reporting experiences after the visit, the Experience Sampling Method was the primary data collection procedure. Six aspects of the wilderness experience were identified, inspired by the writings of Henry David Thoreau, John Muir, AIdo Leopold, Sigurd Olson, and other wilderness writers: oneness, primitiveness, humility, timelessness, solitude, and care. Five modes of experiencing the wilderness were developed based on the work of environmental psychology and leisure scholars: focus on self (introspection), focus on others (socialness), focus on task (task orientation), focus on emotions (emotional intensity), and focus on environment (environmental sensitivity). Confirmatory factor analysis, principal component analysis and reliability analyses were carried out to assess the stability and meaningfulness of the scales used to operationalize these dimensions. Sixty-two visitors were asked to carry and respond to the study questionnaire during multiple moments of their visit to the Okefenokee Wilderness. Oneness, humility, timelessness, and care appeared to be pertinent dimensions of the wilderness experience, as were the more traditionally measured values of solitude and primitiveness. Using a repeated measures analysis of variance, time was a significant factor in determining item response, thus demonstrating the dynamic nature of the wilderness experience. Ideal or peak leisure, operationalized by a combination of three measures of leisure (intrinsic motivation, perceived freedom, and connotative leisure) and high levels of intensity, was found to be correlated with raised feelings of oneness, humility, primitiveness, and solitude. The Experience Sampling Method identified important multiple dimensions of the wilderness experience, and demonstrated the dynamic nature of the experience more vividly than past post-hoc measures. However, the study also identified potential problems of ESM as a data collection instrument in wilderness : concerns of obtrusiveness on the visitor’s experience, behavioral reactance, and respondent compliance. / Ph.

No / This paper contributes to our understanding of compliance with non-mandatory statements of best practice. Specifically, we examine the efficacy of agency-related mechanisms on the degree of disclosure compliance with the ASB Statement on interim reports. Using data drawn from a sample of 259 UK companies listed on the London Stock Exchange, we show that although overall disclosure compliance is high (74.5% of the items of information being disclosed), companies do not fully comply with the ASB Statement on interim reports. We employ an ordinary least square (OLS) regression model to establish whether selected company-specific and corporate governance characteristics (proxying for agency-related mechanisms) are related to the degree of disclosure compliance. Our results indicate that multiple listing, company size, interim dividend and new share issuance are positively associated with the degree of compliance. We also find that the degree of disclosure compliance is positively associated with auditor involvement, audit committee independence and audit committee financial expertise. These results have important implications for policy because they suggest that whilst agency-related mechanisms may motivate compliance with best practice non-mandatory statements, full compliance may be unattainable without regulations.

The problem involved in this study is to determine a satisfactory way in which public schools can adequately revise their scientific evaluation system in order to develop a more effective method of marking and reporting of pupil progress to parents.

The purpose of this study is to determine an adequate and justifiable report to the parents regarding the progress of students in the public schools of the Colbert community, Colbert, Oklahoma.

To be perceived as trustworthy in the eyes of the stakeholders is one of the main assets of any successful firm, for a positive image will reflect positively on business. This study focuses on the analysis of trust-building strategies in Annual Reports (ARs) and Corporate Responsibility Reports (CRRs) of two Swiss banks, UBS and Credit Suisse. The analysis aims to identify the linguistic means used to project a trustworthy image, as well as to point out any changes in their use which might have occurred after the financial crisis of 2008. For this purpose, a corpus of ARs and CRRs from the years 2007, 2012 and 2017 has been compiled. The corpus was analyzed quantitatively and qualitatively to identify the frequency and distribution of lexical expressions indexing competence, benevolence, and integrity. The results, though tentative, provide insights into the use of trust-building linguistic means and their diachronic development.

The equipment, originally, was developed to be used in fixed environments, so it was adapted so that it could be used in conditions of mobility. From the Mobile Measurement Reports (MMRs) RF coverage and the handover process are analyzed. The MMRs enable the identification of the serving cell and the list of the closest neighboring cells monitored by the mobile. This work analyses only data referent to the serving cell and the two closest neighboring cells. Inter-cell and intra-cell handovers are identified. The frequency planning and quality of service offered by the network related to the regions are discussed as well / Esta disserta??o apresenta a aplica??o de um aparelho port?til, PlugData MG100G, equipado com um m?dulo celular, para an?lise de cobertura de radiofreq??ncia em uma rede GSM na cidade de Jo?o Pessoa - PB em quatro regi?es distintas.

It also includes the disclosure of operational risks or operations to meet the new legislation will be effective on January 2016 (CVM Instruction 552). This process has promoted adaptive approach and adoption of new practices of reporting financial and accounting information, as well as has promoted the way the organizations manage their internal processes and operational controls. Especially in financial, banking and insurance sectors that fund productive activities, and motivated by the improvements of due diligence analysis of their customers and borrowers, they have better framed the analysis and identification of operational risks of organizations and are also following the changes promoted by the Organization for Cooperation of Economic Development (OECD). In this way, this study aimed to monitor, update, and analyze the current Organizational practices with regards to their Sustainability Operational Risk reports and the levels of compliance compared with existing risk management framework through structured interviews. To analyze the practices of organizations it has been done 02 studies, using primary data (survey made with organizations employees) and secondary data (financial statements, published integrated reports of sustainability risks). To better support the study, an open survey was conducted (primary data) with companies that are part of ABNT (Brazilian Association of Technical Standards and CEE63 committees - Risk Management), where the results showed that the organizations, for instance, Petrobrás, Netshoes, Inmetro, Furnas, Syngenta, Empresa RBS communication, Sabesp among others, have operational risks management practices and they are consistent with the criteria established by the framework, and they are in implementation phase and in constant process improvement. After applying the sample selection criteria (not probability) and the secondary data, the company named Fibria Celulose has been selected through the analysis of its ISE sustainability reporting, financial statements and integrated risk reporting (years 2013 and 2014 ), and this meets concept terms as well, by contemplating norms/standards and frameworks (standards ISO 26001, 16001, 31000), and is, as described in its own published reports, in preparation phase to meet new requirements of Securities and Exchange Commission (CVM). These processes of adapting organizations, the new requirements recently summarized in the standardization of Accounting practices; the disclosure of risk indexes; the materiality of operational risks; the certification of products/management systems of risk/sustainability and adoption of Environmental & Social Accounting are shown as a new phase of observation of the economic activities in Brazil / A partir do ano de 2010, as organizações, principalmente de capital aberto, vêm atravessando um processo de aperfeiçoamento do processo de divulgação e transparência da divulgação de resultados de operações, que envolve a melhoria das demonstrações contábeis, e de relatórios complementares, a adoção do processo de uniformização das práticas contábeis promovidas pelo International Accounting Standards Board e International Financial Reporting Standards (IASB/IFRS), também pela divulgação de Riscos operacionais ou de operações para atendimento à nova legislação que entrará em vigor a partir de janeiro de 2016 (Instrução CVM 552). Esse processo tem promovido adaptações e adoções de novas práticas de relatos de informações financeiras e contábeis, bem como tem promovido a forma com que as organizações gerenciam internamente seus processos e implementado suas formas de controles operacionais. Principalmente o setor financeiro, bancário e de seguros, que financiam as atividades produtivas, motivados pelo aperfeiçoamento dos processos de análise de riscos de seus clientes e tomadores de empréstimos, tem aprofundado sua forma de análise e aperfeiçoado as práticas de identificação de riscos operacionais das organizações, e acompanhando as modificações promovidas pela Organização para cooperação do desenvolvimento econômico (OCDE). Desta forma, e por este cenário, o estudo teve o objetivo de acompanhar, atualizar e analisar as práticas organizacionais de relatos de Riscos Operacionais de sustentabilidade, e de pesquisar as práticas através de entrevistas estruturadas sobre o grau de aprofundamento frente aos frameworks (padrões) em Gestão de Riscos estabelecidos. Foram Realizados 02 estudos utilizando dados primários (pesquisas diretas com usuários das organizações) e secundários (demonstrações contábeis, relatos integrados de riscos de sustentabilidade divulgados) como forma de analisar as práticas das organizações. Para fundamentar o estudo, foi realizada pesquisa aberta (dados primários) com empresas participantes da ABNT (Associação Brasileira de Normas Técnicas e comitês CEE63 de Gestão de Riscos), onde os resultados demonstraram que as organizações pesquisadas como, por exemplo, Petrobras, Netshoes, Inmetro, Furnas, Syngenta, Empresa RBS de comunicação, Sabesp, entre outras, possuem práticas de Gestão de Riscos Operacionais coerentes com os conceitos estabelecidos por frameworks, estando em fase de implantação e em constante aperfeiçoamento interno dessas práticas. Após aplicados os critérios de seleção de amostras (não probabilísticos), e o estudo de dados secundários, foi selecionada a empresa FIBRIA Celulose, através de análise de relatórios de sustentabilidade ISE, demonstrações contábeis e Relato integrado de riscos (dos anos de 2013 e 2014), e demonstrou atender em termos conceituais, por contemplar os aspectos constantes em normas e frameworks do tema (normas ISO 26001, 16001, 31000), e está, como descrito nos próprios relatórios divulgados, em fase de preparo para atendimento de nova exigência da Comissão de Valores Mobiliários (CVM). Este processo de adaptação das organizações e de novas exigências, resumidas recentemente na padronização das práticas contábeis, na divulgação de índices de riscos e de materialidade dos riscos de operações, da certificação de produtos e sistemas de gestão em Gestão de Riscos e sustentabilidade e adoção de Contabilidade Ambiental e Social, apresenta-se como uma nova fase de observação da atividade econômica no Brasil
