Industry analysis of the high frequency trading industry : an assessment of the industry boundaries, environment and strategic options

O Mercado Acionário Americano evoluiu rapidamente na última década. Este tornou-se uma arquitetura aberta em que participantes com tecnologia inovadora podem competir de forma eficaz. Várias mudanças regulatórias e inovações tecnológicas permitiram mudanças profundas na estrutura do mercado. Essas mudanças, junto com o desenvolvimento tecnológico de redes de alta velocidade, agiu como um catalisador, dando origem a uma nova forma de negociação, denominada Negociação em Alta Frequência (HFT). As empresas de HFT surgiram e se apropriaram em larga escala do negócio de formação de mercado, no fornecimento de liquidez. Embora HFT tem crescido massivamente, ao longo dos últimos quatro anos, HFT perdeu rentabilidade significativamente, uma vez que mais empresas aderiram ao setor reduzindo as margens. Portanto, diante deste contexto, esta tese buscou apresentar uma breve revisão sobre a atividade de HFT, seguida de uma análise dos limites deste setor, bem como, das características do macroambiente do HFT. Para tanto, a tese realizou uma extensa revisão do histórico literário, documentos públicos qualitativos, tais como, jornais, atas de reunião e relatórios oficiais. A tese empregou um ferramental de análise, Barreiras de Entrada e Mobilidade (Porter, 1980); Modelos de Evolução Setorial (McGahan, 2004); Estrutura do Setor de Informação Intensiva (Sampler, 1998), para analisar os limites do setor de HFT. Adicionalmente, empregou as ferramentas de análise, Modelos de Evolução Setorial (McGahan, 2004) e PESTEL (JOHNSON, SCHOLES, and WHITTINGTON, 2011), para analisar o setor e o contexto que envolve o negócio de HFT. A análise concluiu que as empresas que empregam HFT para atuar e competir no mercado acionário, compoem um setor independente.

A Informatização da saúde no Brasil: uma análise multi-paper inspirada na teoria ator-rede

As tecnologias da informação e comunicação (TIC) estão presentes nas mais diversas áreas e atividades cotidianas, mas, em que pesem as ações de governos e instituições privadas, a informatização da saúde ainda é um desafio em aberto no Brasil. A situação atual leva a um questionamento sobre as dificuldades associadas à informatização das práticas em saúde, assim como, quais efeitos tais dificuldades têm causado à sociedade Brasileira. Com objetivo de discutir as questões acima citadas, esta tese apresenta quatro artigos sobre processo de informação da saúde no Brasil. O primeiro artigo revisa a literatura sobre TIC em saúde e baseado em duas perspectivas teóricas – estudos Europeus acerca dos Sistemas de Informação em Saúde (SIS) nos Países em Desenvolvimento e estudos sobre Informação e Informática em Saúde, no âmbito do Movimento da Reforma Sanitária –, formula um modelo integrado que combina dimensões de análise e fatores contextuais para a compreensão dos SIS no Brasil. Já o segundo artigo apresenta os conceitos e teóricos e metodológicos da Teoria Ator-Rede (ANT), uma abordagem para o estudo de controvérsias associadas às descobertas científicas e inovações tecnológicas, por meio das redes de atores envolvidos em tais ações. Tal abordagem tem embasado estudos de SI desde 1990 e inspirou as análises dois artigos empíricos desta tese. Os dois últimos artigos foram redigidos a partir da análise da implantação de um SIS em um hospital público no Brasil ocorrida entre os anos de 2010 e 2012. Para a análise do caso, seguiram-se os atores envolvidos nas controvérsias que surgiram durante a implantação do SIS. O terceiro artigo se debruçou sobre as atividades dos analistas de sistema e usuários envolvidos na implantação do SIS. As mudanças observadas durante a implantação do sistema revelam que o sucesso do SIS não foi alcançado pela estrita e técnica execução das atividades incialmente planejadas. Pelo contrário, o sucesso foi construído coletivamente, por meio da negociação entre os atores e de dispositivos de interessamento introduzidos durante o projeto. O quarto artigo, baseado no conceito das Infraestruturas de Informação, discutiu como o sistema CATMAT foi incorporado ao E-Hosp. A análise revelou como a base instalada do CATMAT foi uma condição relevante para a sua escolha durante a implantação do E-Hosp. Além disso, descrevem-se negociações e operações heterogêneas que aconteceram durante a incorporação do CATMAT no sistema E-Hosp. Assim, esta tese argumenta que a implantação de um SIS é um empreendimento de construção coletiva, envolvendo analistas de sistema, profissionais de saúde, políticos e artefatos técnicos. Ademais, evidenciou-se como os SIS inscrevem definições e acordos, influenciando as preferências dos atores na área de saúde.

Desafios e oportunidades na inserção de uma empresa financeira pública nas redes sociais

Este trabalho tem por objetivo compreender como foi a inserção de uma empresa pública do setor financeiro nas redes sociais virtuais, mais especificamente, no Facebook, buscando entender os motivadores do processo, os desafios enfrentados, as oportunidades encontradas e as possibilidades de melhoria na interação virtual. O estudo se voltou para a percepção dos funcionários que atuaram na implantação, acompanhamento e manutenção da página da referida empresa – aqui chamada de Asmaluan - naquela plataforma virtual. A coleta de dados, através de entrevistas em profundidade tratadas sob a análise de conteúdo, identificou regras e procedimentos específicos para a atuação dos funcionários ligadas à cultura organizacional da empresa, sendo percebidos entraves típicos de uma empresa burocrática, em consonância com a literatura de cultura organizacional e cultura no serviço público brasileiro . Apesar destas dificuldades, principalmente ao entender a implantação, planejamento e execução das atividades postas ou “impostas” pelas redes sociais, foi demonstrada, na visão da empresa em adição à bibliografia estudada, a relevância em estar presente em um novo cenário de inovações tecnológicas trazidas pela internet, pelo impacto sobre a forma de interagir entre clientes e organizações.

O uso do móbile marketing como estratégia de fidelização de clientes :um estudo e empresas do setor de comércio e serviços em natal-RN

This study aims to understand the effects of the mobile marketing use as a relationships tool for companies that operate locally, because of the lack of information about this new marketing tool, as well as the scarcity of studies in this area. This is an exploratory and qualitatively study, based on primary sources, raised through books, articles in the marketing area and the telecommunications industry organs as well as secondary sources. With the purpose to look into the issue, a semi-structured interview is made with the companies managers of the sectors of trade and services in Natal-RN. The advances in technology allow an important discussion focused on the marketing in the new communication technologies scenario. It appears that the mobile marketing adoption and use by local companies is already a reality and companies are awake to changes and technological innovations accessible, especially the mobile telephony as well as convergence with other media. There is, however, that the use of technologies offered by mobile marketing is still limited to the sending of text messages (SMS), despite the numerous possibilities of it use. Moreover, the results obtained with mobile marketing use show that companies can identify them, but there is no effective monitoring in quantity and financial terms. Only affect sales growth and support for progress in loyalty with customers. It shows up that the mentality of not measuring the results still in the plan of changes and technological innovations. The data allow saying that the mobile marketing is a reality, however has not yet signed as a tool for carrying out campaigns and marketing tool for loyalty of customers, despite presenting a wide range of possibilities to streamline and make more effective the marketing businesses process

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Henrique Novaes: técnica, território e cidade em uma trajetória profissional: Brasil, primeira metade do século XX

The career of civil engineer Henrique de Novaes, a remarkable figure in the academic, technical and political fields, demonstrates its extensive and relevant work across Brazil in the first half of the twentieth century. It covered from the design of water supply and sewage works, road and rail transport networks, works against drought in the Northeast, hydroelectric and harbor facilities to the urbanization planning and architectural projects, which displays a systematic and multiple production. City and territory conformed to his fields of verification, practical and above all, transformation. The search for understanding of the inclusion of a social actor in this process thus contributes to the specific analysis of the doings of Henrique de Novaes, who graduated at Polytechnic School of Rio de Janeiro in 1906. From a polymorphic activity in different scales, one tries to figure how, through academic education or professional practice, urban history in Brazil can be told or built. The introduction of technological innovations matched the purposes of planning and urban sprawl, as well as met the specifications of regulation and institutionalization of public infrastructure services at the time. The overall plans proposed by the engineer thought of the city as a whole, interconnected to the structural networks. At the same time, the knowledge of a larger physical scale the territory bounces back in the urban in a relationship of reciprocity and completeness. The objective research, therefore, tries to understand the roles played by Henrique de Novaes s works and academic education in the accomplishment of systematic modernization of Brazilian urban space and territory, recovering a little known historical figure by current historiography. It is proposed, as methodological axis, that the study of this professional career configures itself as an essential element for understanding the idea of progress embodied in the technical studies and proposals for improvements and sanitation nationwide in the first half of the twentieth century . The primary sources for the construction of this analysis were technical articles in journals of the period ( Clube de Engenharia , Viação e Revista Brasileira de Engenharia ), and technical reports, government messages, newspaper articles published at the time, autobiographical reports and the engineer s verbal communications with relatives. The work is structured in three chapters: "Biographical traces, academic education and 'technical and political' activities" illustrates the initiation into the technical, public and political environment; Chapter 2, "Technique and territory" outlines his network understanding through sanitation and transport services; Chapter 3 "Technique and City" describes the influence of polytechnics knowledge on the propositions of modernization of cities; Finally, "Final Thoughts: An Evaluation," presents an overview of the affiliations and practice of an engineer in the different scales, and its contribution to the modernization of Brazilian urban and territorial space

Inovações tecnológicas na caprinocultura

O largo crescimento do setor de agronegócios no Brasil tem estimulado mudanças nos sistemas produtivos, tanto na intensificação, como na profissionalização da produção. Dessa forma, os produtores têm buscado estratégias para melhor atender aos desafios da atividade pecuária atual, dentre as quais se destacam as inovações tecnológicas que devem resultar em comprovado benefício à atividade, seja pelo aumento em produtividade, seja pela melhoria na qualidade dos produtos, seja pela conscientização do respeito ao meio ambiente. Assim como em outros segmentos do agronegócio brasileiro, na caprinocultura existe uma demanda crescente pela aplicação de inovações tecnológicas, uma vez que o sistema produtivo precisa ser mais competitivo para se manter no mercado. Dentre as inovações tecnológicas aplicadas na caprinocultura, foram abordadas as mais relevantes nas áreas de reprodução (desde métodos para indução de cio até a prática da transgenia), melhoramento genético (biogenética), sanidade (inovações no diagnóstico e prevenção de doenças de maior impacto na criação), nutrição (inovações nos sistemas de alimentação) e tratamento de dejetos (diminuição de contaminantes no ambiente). A utilização conjunta das inovações tecnológicas nos diferentes segmentos associados à cadeia produtiva caprina pode fazer com que ocorram melhorias nos rebanhos assim como nos produtos gerados.

Análise dos indicadores de qualidade versus taxa de abandono utilizando método de regressão múltipla para serviço de banda larga

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

Fatores que afetam a competitividade do queijo artesanal: um estudo exploratório no Seridó/RN

This article presents a study on the research of the factors that affect the competitiveness of cheese produced in a craft in the Seridó of Rio Grande do Norte in the perception of rural producers. His theory is based on factors of competitiveness and definitions of craft production. This research was performed in the important area of production and marketing of cheeses from the state. The methodology used was exploratory research descriptive type survey. The research field of 213 returned questionnaires validated. those interviewed were rural producers of artisanal cheese, with properties distributed in the districts located in the region. The results showed the production of artisanal cheese in Seridó / RN's main points of difficulty to compete: the great marketing in the informality, workforce has low skills and education, has little technical assistance, low acceptance by technological innovations and absence of integration between producers which creates low productivity and qualification of the production chain

A influência da adição de caulim, quartzo e feldspato potássico na formulação de massas cerâmicas para telhas: Modelo estatístico

The production of roof tiles in the state of Rio Grande do Norte accounts for around 60% of the total of ceramic pieces produced. There is a need for investment to improve quality and productivity, thereby promoting technological innovations. Accordingly, the aim of this study is to determine the effect of kaolin, potassium feldspar and quartz in two standard formulations, as well as the effect of sintering temperature on the technological properties of linear firing shrinkage, water absorption and bending rupture stress, by fitting the statistical model and using multiple linear regression to assess the relationship between technological properties and independent variables. The raw materials were characterized using the following techniques: X-ray fluorescence (XRF), X-ray diffraction (XRF), rational analysis (RA), differential thermal analysis (DTA) and granulometric analysis (GA). The test specimens were compacted by uniaxial pressure (25 MPa), dried in a stove at 110 ºC for 24 hours and sinterized at 850 ºC, 950 ºC and 1050 ºC and held isothermal for 30 minutes. The results obtained indicate that the addition of kaolin to two standard formulations (M and R) promoted a reduction in water absorption values and an increase in bending rupture stress values. The sintering temperatures for group M that resulted in the lowest linear firing shrinkage and water absorption values were 850 ºC and 950 ºC, respectively, and the highest bending rupture stress values were reached at a temperature of 950 ºC. In the case of group R, the sintering temperature that obtained the lowest water absorption and linear firing shrinkage values was 850 ºC, and the highest bending rupture stress values were attained at a temperature of 1050 ºC. This work explains the statistical approach used to fit the model that describes the relationship between the technological properties and percentage of kaolin, quartz and feldspar, as well as the models that enable predictions, provided that the lower and upper limits of the percentage of clay minerals, flux and quartz used in this study are respected. Statistica 6 software was used and results were obtained by stepwise forward regression

As orquestras invadem as salas de estar: redefinição dos padrões e espaços para a escuta musical no Rio de Janeiro (1926-1931)

In the late nineteenth and early twentieth century, a series of technical innovations have been commercially and widespread on some urban groups everyday, in Brazil. Some of these technological innovations have played an important role in large-scale distribution of artistic works, which until then had an extremely limited potential for diffusion. Development of devices that can record and play music has been mechanically inserted into this logic, while the gramophones, phonographs, cylinders and discs became popular. By this time a new moment for production and consumption of music had started. Especially since the begging of electrical system for registration and production of sounds, this process bought important meaning to the way some peoples in Rio would leasing and sense music, besides it had contributed substantially to changes in the spatial references of these individuals

Manejo de irrigação e nitrogênio no feijoeiro comum cultivado em sistema plantio direto

With technological innovations, such as irrigation, the bean has been grown by producers who have the most varied levels of technology that, in suitable times, allows the planting great success in grain yield. The aim of this study was to evaluate the response of the dry bean to different managements of irrigation and nitrogen fertilization with no-tillage system, in Aquidauana - MS, Brazil. The experiment was conducted at the Universidade Estadual de Mato Grosso do Sul (UEMS), with the soil of the area classified as Alfisol, using the bean crop "Perola" sown on June 30, 2007. The experimental design was a randomized block split-plot consisting of three blocks and two replications within each block. The plots were composed of three management of irrigation, by the Class A pan method, using Hargreaves-Samani equation, and management by tensiometry (-40 kPa), with water replacement of 16.5 mm for all irrigation plots. The subplots consisted on four rates of nitrogen fertilization (0; 50; 100 and 150 kg ha(-1)), in which the nitrogen source was urea. It was concluded that the irrigation management through the Class A pan and Hargreaves-Samani equation conduced to higher grain yields of bean, 3031.11 and 3005.02 kg ha(-1) respectively.
