O usuário e os sistemas de informatização: a utilização do sistema de controle de operações da delegacia legal pelos policiais civis do Estado do Rio De Janeiro.

Organizar racionalmente as informações e sistematizá-las tem sido essencial para o sucesso de diversas empresas. Quando estudamos as instituições destinadas à segurança pública percebemos que o uso de tecnologia e de sistemas de informação são comuns nos exemplos bem sucedidos de combate às práticas criminosas. O Programa Delegacia Legal, inaugurado no Estado do Rio de Janeiro em 1999, acompanha essa tendência e tem como um dos seus pilares a importância ao tratamento da informação. Os policiais que fazem os registros das ocorrências nas delegacias utilizando-se do Sistema de informação (SCO) têm então um papel fundamental porque através desses registros são investigadas as infrações, assim como é alimentado um banco de dados mais completo para ser aliado na elaboração de estatísticas e na aplicação de ações estratégicas. Considerando que esse tipo de registro, utilizando sistemas de informação, alterou a rotina institucional, o presente estudo verifica se existe ou não resistência ao uso do Sistema – SCO, fazendo uma abordagem sobre o sistema de informação, o Programa Delegacia Legal, a cultura organizacional e a opinião dos policiais.

Mudanças de métodos de custeio e o impacto no sistema de informação gerencial: um estudo qualitativo

A presente pesquisa consiste em identificar os impactos causados no Sistema de Informações Gerenciais com a mudança de método de Custeio Variável para Unidade de Esforço de Produção (UEP), mediante a realização de um Estudo de Caso sobre a empresa Bistex Alimentos LTDA. A coleta de dados, viabilizada pela análise documental e pela aplicação de entrevista com dois diretores, tornou possível a análise de dados interpretativa dos indicadores de desempenho presentes nas principais alterações após o processo de migração, na forma de um estudo comparativo, levantando controles usados na organização antes e depois da troca de método. Autores como Johnson e Kaplan (1993), que abordam a contabilidade gerencial, Allora (1996), que introduz os custos e controle gerencial de produção, e Wernke (2008), que aborda a aplicação do Método UEP, deram consistência à aplicabilidade operacional desta proposta. Os principais resultados podem ser identificados no ordenamento de informações, fundamental pelo uso da UEP, o que causa alterações na cultura organizacional da empresa. O estudo demonstra que a implementação do método UEP trouxe alterações nos controles da organização, entretanto, ainda falta uma visão holística e a integração com a gestão estratégica

Potencial de produção de grãos brasileiros via fertilização e impactos nas emissões de CO2eq

Para todos os municípios Brasileiros foram coletados dados de área plantada, quantidade produzida, tipos de solos e uso do solo, para o Arroz, Feijão, Trigo, Milho e Soja. Com o auxílio de Sistema de Informações Geográficas (SIG), mapas foram elaborados, e a partir do cruzamento entre eles, produtividades por tipo de solo em áreas antropizadas foram obtidas. A partir das faixas de produtividades esperadas relativas às faixas de dosagem de adubação por nível de disponibilidade de macronutrientes primários (Nitrogênio, Fósforo e Potássio) no solo, recomendadas pela Embrapa (WebAgritec), considerou-se que cada município, sem nenhuma expansão de área, a partir de seu valor real de produtividade em 2011/12, aumentasse a mesma até o valor máximo esperado e correspondente à recomendação de dosagem de adubação relativa à faixa superior de produtividade. Considerou-se um período de dez anos para a subida de um patamar para outro de produtividade, o que permitiu um horizonte temporal das estimativas de 2011/12 até 2061/62. Projetaram-se os Consumos, Dosagens e Eficiências de Adubação, bem como os Balanços de CO2eq para os macronutrientes primários, necessários e resultantes destas novas condições. O horizonte e os volumes de produção agrícolas resultantes foram comparados com as projeções do MAPA 2021/22 e do Outlook Fiesp 2023. O potencial de volume de produção agrícola via fertilização destas cinco culturas e o impacto no balanço de CO2eq são então mensurados, culminando com a possibilidade de significativas antecipações deste volume em termos de número de safras e com o efeito benéfico no balanço de CO2eq, permitindo em virtude das áreas poupadas, postergação expressiva em termos de emissões de CO2eq

Impactos da adoção de sistemas de informação no judiciário: pesquisa com usuários do sistema processual virtual em um juizado especial federal

The Information Technology (IT) is increasing his applicability to business, both private and public companies. It is necessary the adequate use of the new technologies and get cooperation and technology acceptance of the system. People tend to resist to the changes, contributing so that the technology is rejected or even it is not recognized as promoting of the changes. This study is relevant and aim to evaluate the impacts of new technologies, considering their users as fundamental factors in the change process. The survey analyzed the advantages and the barriers of the system use in three federal special judicial of Rio Grande do Norte, with data collected in May of 2007, through the application of questionnaires to thirty eight users of the virtual system CRETA. The users' perception was evaluated, under the optics of five variables: efficiency, image, agility, ease of use and quality. Starting from the obtained results, it was evidenced that the implementation of the system felt accordingly the expected and it reached the objectives intended that were: the velocity and efficiency in the path of the lawsuits, larger productivity, resulting in a better quality of the final work introduced to the citizen and proportionate an improvement in the organizational image of the judiciary power

Os impactos tecnológicos da implantação da nota fiscal eletrônica: um estudo de casos múltiplos

Increasingly, the Information Technology is used in the society, including the private, public and third sector organizational context. Technological tools are created in order to speed, automate, control and monitor processes. These technologies generate impacts on areas that permeate their use and the objective of this study is to investigate the implementation process of the Eletronic Invoice and the impacts arising from this technological tool in companies. For that, case studies have been conducted in three companies that emit and receive Eletronic Invoice, in a Information System consultancy, that provides softwares of Eletronic Invoice, and in a State Tax Department. Data collection was performed with organizations representatives through electronic questionnaires. The study concludes that it is expected, by the investigated organizations, that the tool reaches the benefits offered by the Tax Administration. However, these benefits have not been identified yet and neither have the use of methodologies in order to identify them. Moreover, the main impact found was the need for better training and participant´s technical qualification, followed by reducing printing costs and paper purchase

Crenças normativas e comportamentais e suas influências na intenção de adoção de um sistema de informação: um estudo na área de compras da UFPA

The study aims to identify the factors that influence the behavior intention to adopt an academic Information System (SIE), in an environment of mandatory use, applied in the procurement process at the Federal University of Pará (UFPA). For this, it was used a model of innovation adoption and technology acceptance (TAM), focused in attitudes and intentions regarding the behavior intention. The research was conducted a quantitative survey, through survey in a sample of 96 administrative staff of the researched institution. For data analysis, it was used structural equation modeling (SEM), using the partial least squares method (Partial Least Square PLS-PM). As to results, the constructs attitude and subjective norms were confirmed as strong predictors of behavioral intention in a pre-adoption stage. Despite the use of SIE is required, the perceived voluntariness also predicts the behavior intention. Regarding attitude, classical variables of TAM, like as ease of use and perceived usefulness, appear as the main influence of attitude towards the system. It is hoped that the results of this study may provide subsidies for more efficient management of the process of implementing systems and information technologies, particularly in public universities

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

Terrenos de marinha: terras públicas com função social? um estudo da orla marítima de natal

This work has as its theme the social function of terrenos de marinha. Theresearch universe is the terrenos de marinha of Natal coastline, focusing on thefulfillment of its social function. Prescribed by law since the colonial period with thepurpose of protecting the coast and free movement of people and goods, theywere swathes of land not available to private use by individuals. With the transitionfrom the allotments system to the purchase and sale, regard to land access,crystallized with the creation of the Land Law in the nineteenth century, the land isheld as merchandise and terrenos de marinha, following this logic, also acquireexchange value and become capable of enjoyment by private individuals, with thecondition of tax payments to the state. This is seen until the twentieth century,when in 1988, primarily because of the Federal Constitution promulgation, begins anew cycle when is possible to use on terrenos de marinha the principle of thesocial function of property. From this perspective this study aims to identify thesocial function of terrenos de marinha in Natal, focusing on the public destinationand the use value of the city coastline. To this end, it was made a data collection inthe on-line information system of the Federal Heritage Department of Rio Grandedo Norte (SPU / RN) and in the terrenos de marinha areas, in order to find out ifthey had public or private use, or if they were empty lots, as well as if thepopulation access to the shore exist. Interviews with managers of the SPU weremade. The empirical study showed that the social function of terrenos de marinhain the city of Natal still didn´t happen, considering the constant existence of vacantlots in their areas, the lack of access in significant portions of the coastline and thereduced areas directed to common use along the coastline, minimizing its potentialof enjoyment by the population. It concludes by pointing to the existence of a newtransition phase on the terrenos de marinha, in witch, gradually, come up lawprovisions in the legal system and public policies to expand the purely taxcollection function attributed to this land for two centuries. In this direction, thesocial function of terrenos de marinha is embodied in concomitant adjustment ofthe tax collection function and the rescue of coastline use value, national heritageand a place for sociability and social relations development

Entre serras e sertões A(s) (trans)formaç(ões) de centralidade(s) da Região Metropolitana do Cariri/CE

This study reviews the spatial configuration from the road network of an urban compound formed by the cities of Crato, Juazeiro do Norte and Barbalha (the Crajubar - core of the Cariri metropolitan region, in the State of Ceará, Brazil), in order to establish nexus (or relations) between different levels of accessibility and the formation/ transformation and specialization of centralities in local and metropolitan scales. Stemming from the Social Logic of Space theoretical and operational apparatus, the study explores modeling possibilities (with axial lines, segments and lines of continuity) which is then confronted to empirical observations concerning movement flows and land use, within a Geographic Information System database. At different scales of analysis, the results suggest evidences of continuity were found in the permanence of intra-urban centres and sub-centres within each town, whereas evidences of change pointed out to the formation of a new centrality of metropolitan magnitude in the neighbourhood referred to as the Triângulo, in the municipality of Juazeiro, where high levels of topological accessibility coincides with the appearance of new business buildings as well as with the emergence of urban equipment of a scale more adequate to meet a regional demand

Spatial variability of soil CO2 emission in a sugarcane area characterized by secondary information

Soil CO2 emission (FCO2) is governed by the inherent properties of the soil, such as bulk density (BD). Mapping of FCO2 allows the evaluation and identification of areas with different accumulation potential of carbon. However, FCO2 mapping over larger areas is not feasible due to the period required for evaluation. This study aimed to assess the quality of FCO2 spatial estimates using values of BD as secondary information. FCO2 and BD were evaluated on a regular sampling grid of 60 m × 60 m comprising 141 points, which was established on a sugarcane area. Four scenarios were defined according to the proportion of the number of sampling points of FCO2 to those of BD. For these scenarios, 67 (F67), 87 (F87), 107 (F107) and 127 (F127) FCO2 sampling points were used in addition to 127 BD sampling points used as supplementary information. The use of additional information from the BD provided an increase in the accuracy of the estimates only in the F107, F67 and F87 scenarios, respectively. The F87 scenario, with the approximate ratio between the FCO2 and BD of 1.00:1.50, presented the best relative improvement in the quality of estimates, thereby indicating that the BD should be sampled at a density 1.5 time greater than that applied for the FCO2. This procedure avoided problems related to the high temporal variability associated with FCO2, which enabled the mapping of this variable to be elaborated in large areas.

Qualidade do gasto público em educação para os municípios da região metropolitana de Natal-2007

The aim of this thesis is to evaluate the quality of public spending on education for the municipalities of the Metropolitan Region of Natal (RMN) in 2009 by use of two theories: The Theory of Welfare (Welfare State) and the Public Choice Theory (TEP), both important to understand the relationship between education and economics. The study also uses principles of microeconomics and public sector economics to get a better idea of the role of education in economy and society. It describes the development of the educational policy in Brazil from 1988 to the Federal Constitution of 2010, following the major changes in basic education during each government. The characteristics of the RMN municipalities were illustrated with socioeconomic indicators, while educational indicators were used to characterize each municipality regarding education. The model used in this study was developed by Bertê, Brunet and Borges, the data was collected on the back of the School Census 2009 and the Brazil Exam 2009 and it was processed quantitavely in the Information System on Public Budgets in Education (SIOPE) by use of the statistical method called standardized score of the normal cumulative distribution function. The quality of public spending on education is the result of the relation between performance indicator ratio and expense ratio. For the qualitative analysis of results, the criteria of efficiency, efficacy and effectiveness were used. The study found that municipalities with higher expenses showed a worse quality of spending and failed to convert the expenditure incurred into performance, thus confirming ineffectiveness

O projeto politico pedagógico de enfermagem e o sistema único de saúde: a visão de discentes

This research aims to analyze, in the view of students, the pedagogic project of undergraduate nursing course, of UFRN, and its articulation with the SUS, in an attempt to understand the issues that permeate the teaching and learning of nursing. This is a qualitative study that used the focus group technique as a tool to collect empirical data. There were three meetings, where we had the collaboration of 23 graduating students from the eighth period of the semester 2009.1. For the analysis of information, we use a theoretical framework based on curriculum guidelines and basic principles of the SUS, making the analogy of the results with the metaphor of Greek mythology, Ariadne's thread, in dialogue with authors who discuss education as a transformative practice. Thus, the texture of the yarn was built of five thematic fields: joint the pedagogic project with the SUS; the teaching/service and theory/practice relation; interdisciplinarity or transdisciplinarity; didactic/methodological and relational approaches; and co-participation of students in the pedagogic project. According to the discussions, we find many difficulties in the teaching and learning process of undergraduate nursing in UFRN to strengthen the SUS, including: dislocation of educational institutions with services, professionals, managers and community; dichotomy between theory and practice; reality of services as a learning field and working process in health; posture adopted by professionals, teachers and other subjects included in the process of health education; decontextualization and fragmentation of teaching with the practice in health and nursing; excessive use of very illustrative methodologies, but little problem-solving; difficult and precarious situation in the relations between teachers and between teachers/students, regarding the acceptance of differences; absence of participation of students in the evaluation process and conduct of the educational project in progress. In this sense, we understand the need an auto-reflexive act of teaching and conducting collective pedagogical course with a view to achieving the SUS. Thus, it is necessary to support practices motivated by the polyphonic dialogue and the exercise of symbiosis and autopoiesis of subjects/actors jointly responsible for the ongoing process of learning for life.

Potencial de erosão da bacia do Rio Uberaba

Este trabalho teve por objetivo identificar qualitativamente as áreas suscetíveis à erosão laminar na bacia do Rio Uberaba, localizada em Uberaba -MG, apoiado no modelo matemático da Equação Universal de Perda de Solo (EUPS). Foram utilizadas cartas de: solos, uso e ocupação das terras, redes de drenagem, declividade e dados pluviográficos, utilizando-se de um Sistema de Informação Geográfica (SIG -IDRISI). A espacialização do potencial de erosão só foi possível a partir da estimativa da tolerância às perdas laminares para cada tipo de solo da bacia, e da profundidade dos solos, por entender que as perdas são mais significativas em solos mais rasos do que em solos muito profundos. Na análise dos resultados, verificou-se que 37% da área total da bacia do Rio Uberaba (905,24 km²) sofrem perdas de solos acima do limite de tolerância, sendo 12% em solos profundos e 25% em muito profundos, e a espacialização deste evento favorece a adoção de ações efetivas quanto à conservação dos solos da bacia.

Uma perspectiva de extensão do modelo de aceitação de tecnologia para explicar o uso de linguagens de desenvolvimento WEB: pesquisa com desenvolvedores Pyton e Java

The spread of the Web boosted the dissemination of Information Systems (IS) based on the Web. In order to support the implementation of these systems, several technologies came up or evolved with this purpose, namely the programming languages. The Technology Acceptance Model TAM (Davis, 1986) was conceived aiming to evaluate the acceptance/use of information technologies by their users. A lot of studies and many applications have used the TAM, however, in the literature it was not found a mention of the use of such model related to the use of programming languages. This study aims to investigate which factors influence the use of programming languages on the development of Web systems by their developers, applying an extension of the TAM, proposed in this work. To do so, a research was done with Web developers in two Yahoo groups: java-br and python-brasil, where 26 Java questionnaires and 39 Python questionnaires were fully answered. The questionnaire had general questions and questions which measured intrinsic and extrinsic factors of the programming languages, the perceived usefulness, the perceived ease of use, the attitude toward the using and the programming language use. Most of the respondents were men, graduate, between 20 and 30 years old, working in the southeast and south regions. The research was descriptive in the sense of its objectives. Statistical tools, descriptive statistics, main components and linear regression analysis were used for the data analysis. The foremost research results were: Java and Python have machine independence, extensibility, generality and reliability; Java and Python are more used by corporations and international organizations than supported by the government or educational institutions; there are more Java programmers than Python programmers; the perceived usefulness is influenced by the perceived ease of use; the generality and the extensibility are intrinsic factors of programming languages which influence the perceived ease of use; the perceived ease of use influences the attitude toward the using of the programming language
