Cryptocurrencies are gaining prominence among individuals and companies alike, resulting in the growing adoption of so-called cryptocurrency wallet applications, as these simplify carrying out transactions. These wallets are available in a myriad of different forms and specifications. For example, there are hardware and software wallets. The latter can be divided into mobile, web, and desktop wallets. All of them offer attackers various ways to exploit vulnerabilities and steal money from victims. It is hard to keep track of this multitude of options and thus choose the right cryptocurrency wallet. For this reason, in this thesis, we collect the findings from previous literature to provide an overview of the various attack surfaces, possible countermeasures, and further research. Our systematic study has shown that there is still a considerable variety of attack vectors, which we have divided into six subcategories, (i) Memory and Storage, (ii) Operating Systems, (iii) Software Layer, (iv) Network Layer, (v) Blockchain Protocol, and (vi) Others. Some of the identified vulnerabilities have currently no solutions at all or hardly applicable countermeasures. However, some are easy to fix and simple to implement. One of the essential measures is to raise awareness of the identified weaknesses and the associated mitigations, if any, among the involved stakeholders, including users, developers, and exchanges.

In May 2018, the European Union enacted the General Data Protection Regulation (GDPR). I examine its impact on firms’ internal information quality (IIQ) and operating efficiency in the United States. Although privacy regulations, such as GDPR, target one subset of firms’ information assets (i.e., personal data), academics and practitioners have emphasized the ability of these regulations to drive broad improvements in firms’ information management practices resulting in higher quality information available for decision making and, by extension, more efficient operations. At the same time, GDPR’s regulatory mandates are likely to burden operations. Using multiple modeling approaches to identify the effect of GDPR on US firms and a variety of IIQ proxies from financial reports and disclosures, I find that (a) GDPR leads to improvements in IIQ for impacted firms and (b) that these improvements in IIQ are beneficial to firm operations. However, the regulatory burden of GDPR has overwhelmed these benefits resulting in a negative net effect on firms’ operating efficiency. / Business Administration/Accounting

The purpose of this pilot and main study was to examine teachers' perceptions of the post No Child Left Behind (NCLB) elementary classroom, the perceived changes, and the implications for teachers' feelings of empowerment and student test anxiety. Previous investigators have agreed that the teacher's voice has been missing, but needed in test anxiety research. By engaging veteran teachers who had experience both before and after the enactment of NCLB in reflective conversation about their experiences, valuable information was gained concerning whether or not teachers felt empowered to perform their duties and what impact they perceived that high stakes standardized testing has had on both teacher anxiety and student test anxiety. This information could be used to inform educational practice and decision making. Triangulation of data sources included narrative data collected through face-to-face interviews with the teachers, the writing of field notes, interview process notes, and reflective journal entries from both the pilot and main studies. Three clear themes emerged that fit the division of the data by the research questions: change in the teachers' experiences, change in teaching vocabulary, and change in the students' experiences. These themes emerged through a process of categorical-content perspective analysis for coding the data and sorting it into themes. The Hermeneutic narrative analysis approach was used to analyze and identify the meaning of these related experiences and stories. The context of the pilot and main studies was elementary schools in a rural school system in the Southeastern United States. The participants were eleven elementary teachers from grades three through five with experience before and after NCLB enactment who taught core academic subjects. Member checks of the interview transcripts and data analysis enhanced the credibility of these reports. The analysis revealed both positive and negative perceptions of the changes in the classroom experience of these elementary teachers, their feelings of empowerment, and the impact of the changes on the test anxiety of their students. Participants across the pilot and main studies indicated that increased stress, pressure, frustration, and professional struggles have had a negative impact on teacher anxiety, teacher efficacy beliefs, and student test anxiety. / Ph.

No. of bitstreams: 1 ALANA RAMOS ARAÚJO - DISSERTAÇÃO (PPGRN) 2011.pdf: 4304665 bytes, checksum: 2efcda3c529f49b9d1315827ac6d752f (MD5) Previous issue date: 2011 / Capes / A mudança da gestão hídrica centralizada para a gestão descentralizada dos recursos hídricos na agenda jurídica brasileira veio com o paradigma democrático pespegado nos documentos hídricos mundiais, na Constituição da República Federativa do Brasil de 1988 e na Lei nº 9.433/97, denominada Lei de Águas. O órgão que se aproxima por excelência desta proposta de gestão descentralizada é o Comitê de Bacia Hidrográfica (CBH), pois nele estão representados o Poder Público, a Sociedade Civil e os Usuários de Água. A Paraíba sujeita-se aos comandos desta legislação hídrica inovadora e, não obstante sua política hídrica datar de 1996, os novos arranjos introduzidos alcançam necessariamente a norma jurídica paraibana. Contudo, só no ano de 2006 o Comitê de Bacia Hidrográfica do Rio Paraíba (CBH-RIO PB) foi criado para gerenciar de forma descentralizada as questões hídricas desta bacia. Algumas pesquisas foram realizadas direta ou indiretamente sobre este colegiado, todavia, a análise sistemática da atuação do comitê desde a sua formação até a atualidade não havia sido feita, fato que impulsionou a indagação da pesquisa: quais as relações produzidas pelo CBH-RIO PB entre 2006 e 2011? Para solucionar a problemática levantada, a pesquisa propôs uma abordagem sistemático-interdisciplinar do CBH-RIO PB sob as dimensões jurídico-institucional, sociotécnica e ambiental, cujo objetivo é realizar análises comparadas com outros comitês estaduais brasileiros que apresentam estágio de atividade consolidado e avançado. O marco teórico de sustentação do trabalho perpassa pelos documentos internacionais que influenciaram a ordem jurídica brasileira, pelas leis nº 9.433/97 e nº 6.308/96 que determinam as normas gerais de formatação dos CBHs no Brasil e na Paraíba, respectivamente. O método da pesquisa constituiu-se de argumentação dedutivo-comparativa que partiu das premissas gerais contidas na Lei de Águas sobre CBHs para analisar o comitê paraibano através de comparação com comitês que possuem modelos mais consolidados. Para tanto, a comparação foi feita através dos Regimentos Internos destes comitês e do comitê do rio Paraíba, cujos documentos normativos foram coletados nos sites oficiais dos Governos Estaduais e de entidades a estes vinculadas. Sem embargo, as Atas e as Deliberações do CBH-RIO PB foram analisadas, pois o seu conteúdo consiste em fontes de dados importantes sobre o comitê. Os resultados obtidos apontam que o Regimento Interno do CBH-RIO PB padece de fragilidades que dificultam sobremaneira a execução das competências que cabem ao comitê, repercutindo de forma negativa na sustentabilidade jurídico-institucional, sociotécnica e ambiental da bacia. Assim, sugere-se a reforma do Regimento Interno do comitê paraibano tomando como referência os regimentos dos comitês participantes da comparação. / The change from a centralized and water management into a decentralized management of water resources in the Brazilian legal agenda came with the democratic paradigm ascribed in the world water documents, in the 1988 Constitution of the Federative Republic of Brazil and in the Law n. 9.433/97, called Water Law. The organism that best approaches the decentralized management proposal is the River Basin Committee (RBC), because it includes members of the Government, the Civil Society and Water Users. The State of Paraíba is submitted to the commands of this innovative water legislation and, although its water policy dates back from 1996, the new arrangements introduced necessarily reach the legal standard of the State. However, only in 2006 the River Basin Committee of Paraíba (RCB-RIO PB) was created to manage the water issues of this basin in a decentralized way. Few studies have been conducted directly or indirectly in this college. However, the systematic analysis the committee‟s performance since its formation until today had not been presented, a fact that raised the research question: what are the relations produced by RCB-RIO PB between 2006 and 2011? To solve the existing problems, the research proposes a systematic, interdisciplinary approach to the RCB-RIO PB under the legal-institutional, socio-technical and environmental dimensions, the goal of which is to conduct a comparative analysis with other Brazilian state committees whose stages of activity are consolidated and advanced. The theoretical rationale of the work permeates the international documents that influenced the Brazilian legal system, by Acts n. 9.433/97 and n. 6.308/96, which determine the general rules for formatting RBCs in Brazil and in the State of Paraiba. The research method consisted of comparative-deductive reasoning that stemmed from the general premises contained in the Water Law regarding the committee to review RCB-RIO PB by comparing it with other committees. Therefore, the comparison was made through the bylaws of these committees and the committee of Paraíba River, whose normative documents were collected from the official websites of the State Governments and their related entities. Nevertheless, the Acts and Resolutions of the RCB-RIO PB were analyzed, because its content consists of important data sources concerning the committee. The results obtained indicate that the bylaws of RCB-RIO PB suffers from weaknesses that greatly hinder the execution of the powers vested in the committee, reflecting negatively on the legal-institutional, sociotechnical and environmental sustainability in the basin. Thus, it is suggested the reform on the RCB-RIO PB bylaws through a comparison with the internal rules of the committees used in the research.

In this paper, I investigate the use of SWOT analysis and the resource based view as tools to elaborate a business plan and in academic research by assessing the two methods’ strengths and weaknesses.   I found that SWOT analysis is useful to structure and prioritise information in a short and concise way. Even though, the information and the information collection methods as well as the concepts and theories used in combinaton with the model and their quality is of the most importance for a proper use of the model.   The resource based view is useful to reflect over which internal resources are the most valuable for the company, even though it can be difficult to assess the most important assets, i.e. the intangible assets. I also found that the fact that the resource based view, which is a explanantory theory, is used as a predicative theory causes uncertainaty and is problematic.

The thesis deals with the phenomenon of "Family business". The first part involves theory aimed at the global importance of family businesses, their specifics, definition, strong and weak sides and potential difficulties. The process of succession and its strategy is described in more detailed way enabling future success of family businesses. The second part shows analyses of Czech family companies. There is a comparison with German family companies which might serve for some improvement of the Czech family entrepreneurs. At the end of this thesis, there are three case studies of three Czech family companies. On the basis of their analysis is provided a recommendation of potential solutions of their problematic areas.

First part of my work deals with strategy, strategic management, strategic analysis and describes individual analysis. The practical part begins with the company presentation. In the practical part were used analysis such as PEST analysis, "4C" analysis , Porter's 5F model, analysis of enterprise resources or financial analysis. At the end of my work are shown conclusions and recommendations for company.

Audit firm tenure impacts the quality of audit work and the disclosure of material internal control weaknesses. Public firms are required by the Sarbanes Oxley Act of 2002 (SOX) Section 302 to disclose material internal control weaknesses. Researchers debate whether audit firm rotation is necessary for improving audit quality (Chen, Lin, & Lin, 2008). Generally, an auditor needs sufficient time to become familiar with a client's business in order to enhance effective controls and financial reporting. However, long tenure may diminish auditor independence, and in turn reduce the quality of audit work and encourage a client to violate SOX disclosure requirements. Therefore, it is expected that the disclosure of material internal control weaknesses is less likely given long audit tenure. Prior studies consider many variables that impact the disclosure of control weaknesses, except audit tenure. Further, prior studies do not address the issue of whether familiarity or independence explains non-disclosure. This dissertation investigates the role of audit firm tenure and concludes that the disclosure of material internal control weaknesses is more likely given short tenure. Further, familiarity with the client's business, which is associated with long tenure, explains non-disclosure and not the lack of independence. Therefore, audit firm rotation may not be necessary.

Developmental mathematics is a problem for many college students due to high failure rate. The purpose of the study was to evaluate the effectiveness of the redesigned course, Math 24. The evaluation examined success, retention, and persistence outcomes of the redesigned course compared to the previous developmental math course. The course's academic and environmental strengths and weaknesses were assessed from the students' and instructors' perspectives. The study utilized the theoretical and conceptual frameworks of Tinto's retention model, Astin's I-E-O model, and Wlodkowski's culturally responsive teaching. A mixed methods program evaluation was employed for the case study using an ex post facto analysis of quantitative data from the college's student database and interviews from 16 students, 4 faculty members, and 1 program director administrator. Quantitative data on persistence, retention and student success rates were analyzed using descriptive statistics to evaluate the outcomes of the redesigned course. Qualitative data from student focus groups and faculty interviews were analyzed using constant comparison analysis to evaluate redesign effect on students. The findings suggested that the redesigned math course's curriculum, resources, assignments, assessments, and the physical classroom setting had many advantages, and assignments and assessments posed major challenges. Online resources, peer collaboration, indirect instruction were strengths; word problems, and the final exam posed the biggest challenges for most students. Retention, persistence and success rates fluctuated over the years and the expected outcomes were not achieved. The social change implication of the redesigned developmental math project study is that faculty should seek students' feedback to help faculty with effective decision making.
