Construção das capacidades organizacionais de tecnologia da informação no contexto dos sistemas institucionais integrados de gestão da UFRN

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

O marketing e a atuação social das empresas: uma relação possível

The present work is about a study of multiple cases with exploratory and descriptiveperspective and qualitative emphasis. Its field of study is constituted by three local companieswith description of social performance, with emphasis in the personal interview with thecontrollers. Its main objective consists of understanding as it has occurred the marketingrelation with the enterprise social performance in the context of these companies located inthe State of the Rio Grande do Norte who carry out social investments. For this, it hassearched to analyze the types and characteristics of the developed social actions, to evaluatethe motivations and objectives of the accomplishment of social actions, to verify theimportance and influence of the social performance in the dynamics of the companies, toverify the level of specific knowledge and information in the areas of marketing and socialperformance in the companies and to evaluate the process of communication (promotion andspreading) of the social performance carried out by the companies. It has been verified thatthe company A directly associates it its social and ambient activities with differentiationbenefits, competitiveness, creation of value, loyalty, relationships, image, prestige,positioning of the company, sale and financial return, beyond benefits in the internal level asbigger motivation of its employees and retention of talents, not existing rejection to theinterlacement of the concepts related to the marketing and the social one. Already in companyB rejection in relating its practical social to the marketing, being observed after posteriorquestionings, that the relation of direct and indirect form exists and those divulgations of theseactions are carried out, contradicting the arguments of the controllers of that the actions wouldnot be carried out to generate media. In company C, it been verified rejection andcontradiction with relation to the concepts related to the marketing, alleging itself that theimage of the harnessed company to its social performance is not used in proper benefit,evidencing itself that this company divulges its action and is marketable benefited, even so isnot this the main objective of its social programs. It has concluded that the association ofthese two concepts is positive and favorable to the development of the businesses and thesocial actions of the companies, legitimizing them and benefiting the involved company,groups in the actions and the society that profits socially from the private social involvement in the social matters

Utilização de soluções business-to-business (B2B) no segmento downstream da cadeia de suprimentos de uma distribuidora de combustíveis

The pursuit of competitive advantage is lobbying organizations to strategically plan the use of their material, human, technological and financial resources, so that it s possible to add value to the product, even when it is considered a commodity. The scenario for this planning should not be limited to the company in question, but cover an entire supply chain, which is composed of several organizations which have common goals of growth and sustainability of the market. They should form trade links, integrating the chains of individual values, in a perspective of value system. In this supply chain there is a flow of services, payments and information, as products well as. The training of these links can be supported by the adoption of a set of information technology, here called solutions business-to-business (B2B), which will be responsible for the production, storage and distribution of relevant information to business transactions between the companies involved. On this view, this thesis aims to describe the B2B solutions adopted in the downstream segment of the supply chain of a distributor of fuel and the nature of these technologies as well as their impact on the creation of value for business and optimization of the relationship between companies. This is a case study on a national distributor of fuels, from a model of research produced under the influence of theories of integrated logistics system and value of Michael Porter. The analyses came to the conclusion that information technology is perceived as an essential tool to the operation of all activities carried out by the company. Among them, at was also brought the key activities of integrated logistics: administration of applications, inventory management, management transport and customer services, which were highlighted in this study. It was also noticed that even these activities are, in principle, purely operational; they all had in the adoption of strategies for leadership in cost or differentiation, supported by B2B solutions identified, making it more conducive to business and direct customer, the clinic reseller of fuel, to obtain value and benefits of this market segment as competitive

Fusões e aquisições no Brasil: análise dos efeitos em mercado de capitais

This study investigated the impact caused by events horizontal mergers and acquisitions (M&As) horizontal, in the stock returns of the participating companies and competitors regarding the creation or destruction of value for those firms in Brazil, from 2001 to 2012. For this, first was used the event study methodology to estimate abnormal returns in stock prices; after was conducted an analysis multiple regression. The results of the event study showed that using sub-periods for the data, before and after the crisis period, the effects were different for the target-before negative, after positive. Regarding the acquirer and competitors, the results were constant. For acquirer firms, the returns were close to zero, while for the competitors were negative. Furthermore, the regression results regarding the bidder showed that firms invested in processes of M&As to obtain a further increase its efficiency. Furthermore, this study indicated that the leverage of the bidder plays is important for creating value in acquisitions, when they has a higher Tobin’s Q. The results of target firms showed that a small firm had a better return than large firm did.

Simulação computacional de medidas estereológicas em estruturas de metal duro (WC-Co)

This work focuses on the creation and applications of a dynamic simulation software in order to study the hard metal structure (WC-Co). The technological ground used to increase the GPU hardware capacity was Geforce 9600 GT along with the PhysX chip created to make games more realistic. The software simulates the three-dimensional carbide structure to the shape of a cubic box where tungsten carbide (WC) are modeled as triangular prisms and truncated triangular prisms. The program was proven effective regarding checking testes, ranging from calculations of parameter measures such as the capacity to increase the number of particles simulated dynamically. It was possible to make an investigation of both the mean parameters and distributions stereological parameters used to characterize the carbide structure through cutting plans. Grounded on the cutting plans concerning the analyzed structures, we have investigated the linear intercepts, the intercepts to the area, and the perimeter section of the intercepted grains as well as the binder phase to the structure by calculating the mean value and distribution of the free path. As literature shows almost consensually that the distribution of the linear intercepts is lognormal, this suggests that the grain distribution is also lognormal. Thus, a routine was developed regarding the program which made possible a more detailed research on this issue. We have observed that it is possible, under certain values for the parameters which define the shape and size of the Prismatic grain to find out the distribution to the linear intercepts that approach the lognormal shape. Regarding a number of developed simulations, we have observed that the distribution curves of the linear and area intercepts as well as the perimeter section are consistent with studies on static computer simulation to these parameters.

Análise do modelo de gestão implantado no Centro de Atenção Psicossocial CAPS II OESTE de 1995 a 2005, situado no distrito sanitário Oeste do município de Natal/RN, à luz da Co-gestão

This dissertation has as aim the praxis of co-management of the health service of CAPS II OESTE of Natal-RN, where health workers, family members got to materialize guidelines and principles of psychiatric Brazilian reform in real possibilities of subjectivity construction, whereas they changed social relations in daily life. The path chosen to record was from testimonials and contributions of those who meant their done. Redeeming this story from social representations of the majority of their builders was an instigating, delicate and rewarding task, emphasizing the living memory, rebuilt in a line of time which could not be found in simple documentary collections. Mainly, by knowing that service routine was intense and had as characteristic the singular mobility itself from a creation process and therefore not always its dynamic allowed adequate records. At the same time, from this occurred the field and bibliographic research which allowed the detailed information from the prior milestones and motivated to the practice here reported. The rereading of concepts in an interface with the reports of the interviewees enabled the verification that the model of mental health advocated by psychiatric reform was understood. Once noticed the presence of the beliefs and values of people in motivating energy for the progress of reform, it has gone to fetch theoretical subsidies of administrative order to understand how they saw this building and that uniqueness has been printed. The theoretical way and praxis have tracked here has allowed to analyze how occurred such a process of production and subjectivity and collectives that when organize enabled themselves for analysis and intervention, including in crisis situations. Therefore, it was revealed that ethical and multi-disciplinarity, the humanitarian sense, the coresponsibility, co-production and horizontal management were the key factors for spread from a changing protagonist. One can thus conclude that co-management from that collective has been multi-disciplinary weaving a cross

Análise estatística das emissões de CO e HC produzidas por gases da exaustão veicular oriundos de gasolina, GNV e mistura álcool/gasolina

The vehicles are the main mobile sources of carbon monoxide (CO) and unburned hydrocarbons (HC) released into the atmosphere. In the last years the increment of the fleet of vehicles in the municipal district of Natal-RN it is contributing to the increase of the emissions of those pollutants. The study consisted of a statistical analysis of the emissions of CO and HC of a composed sample for 384 vehicles with mechanization Gasoline/CNG or Alcohol/Gasoline/CNG of the municipal district of Natal-RN. The tests were accomplished in vehicles submitted to Vehicular Safety's Inspection, in the facilities of INSPETRANS, Organism of Vehicular Inspection. An partial gases analyzer allowed to measure, for each vehicle, the levels of CO and HC in two conditions of rotation of the motor (900 and 2500 rpm). The statistical analysis accomplished through the STATISTICA software revealed a sensitive reduction in the efficiency of the converters catalytic after 6 years of use with emission average it is of 0,78% of CO and 156 (ppm) of HC, Which represents approximately 4 (four) times the amount of CO and the double of HC in comparison with the newest vehicles. The result of a Student s t-test, suggests strongly that the average of the emissions of HC (152 ppm), at 900 rpm, is 40% larger than at 2500 rpm, for the motor without load. This result reveals that the efficiency of the catalytic conversion is limited kinetically in low engine speeds. The Study also ends that when comparing the emissions of CO and HC considering the influence of the fuels, it was verified that although the emissions of CO starting from CNG are 62% smaller than arising from the gasoline, there are not significant differences among the emissions of HC originating from of CNG and of the gasoline. In synthesis, the results place the current criteria of vehicular inspection, for exhaust gases, in doubt, leading the creation of emission limits of pollutant more rigorous, because the efficiency of the converters catalytic is sensibly reduced starting from 6 years of use. It is also raised the possibility of modifications in the test conditions adopted by the current norms, specifically in the speed engine, have seen that in the condition without load the largest emission indexes were registered in slow march. That fact that allows to suggest the dismissal of the tests in high speed engine, reducing the time of inspection in half and generating economy of fuel

Evaluation of the castability of a Co-Cr-Mo-W alloy varying the investing technique

O objetivo deste estudo foi comparar a fusibilidade de ligas de Co-Cr-Mo-W (Remanium 2000), Ni-Cr (Durabond) e Co-Cr-Mo (Vera-PDI), incluídas em revestimentos à base de fosfato, sílica ou utilizando uma técnica mista. Uma rede de nylon quadrada (10 X 10 mm) com 100 espaços abertos serviu de modelo para construção de padrões de cera, que foram incluídos com revestimento à base de sílica, revestimento fosfatado e técnica mista (camada de revestimento fosfatado com 2 mm de espessura + revestimento à base de sílica). Quarenta e cinco espécimes (5 para cada condição experimental) foram fundidos sob chama de gás-oxigênio e a seguir jateados com óxido de alumínio. O número de segmentos fundidos completos foi contado para obter uma percentagem designada como "valor de fusibilidade", representando a precisão da liga em reproduzir os detalhes do molde. A análise estatística por meio de ANOVA a dois critérios e teste Tukey mostrou que, comparando-se as ligas, a Remanium 2000 teve fusibilidade estaticamente semelhante (p>0,05) à da Vera PDI e inferior à da liga Durabond (p<0,05). Considerando os resultados da técnica mista, a liga Remanium 2000 teve menor valor de fusibilidade (p<0,05) que as ligas Durabond e Vera PDI, que apresentaram valores estatisticamente semelhantes entre si (p>0,05). Concluindo, a fusibilidade da liga de Co-Cr-Mo-W (Remanium 2000) foi comparável à da liga de Co-Cr (Vera PDI) e inferior à da liga de Ni-Cr alloy (Durabond). À exceção da liga Remanium 2000, a técnica de inclusão mista aumentou consideravelmente a capacidade das ligas testadas de reproduzir os detalhes do molde, quando comparada à técnica de inclusão em revestimento fosfatado. A técnica de inclusão mista representa uma alternativa para melhorar a fusibilidade de ligas de metais básicos sem afetar a qualidade superficial das peças metálicas.
