Informação orgânica como insumo estratégico para a tomada de decisão em ambientes competitivos: estudo nas empresas do setor varejista situadas na cidade de Marília/SP

The focus of this research is centered on organic information production, sharingand use on the enterprise decision making process. The information on the present economy becomes value source for organizations. The organic information is produced on the organization s internal environment been a product of the activities made by execution its functions. Knowing the elements that involve this process gives a great help to managers once the decision making process is permeated by conflicts and different perceptions. Therefore, the organic information can reduce these conflicts on organizational contexts, because it reduces the uncertainness, propitiates more security and more trustworthiness to the decision making process, besides it gives dynamism to people s time involved on the process. The investigated universe was composed by the companies affiliated to Construnova Net, from construction material segment, located at Marilia Region s cities, Sao Paulo State, because it is an important segment which influences the local and regional economy. The methodological proceedings used are based on the qualitative approach which method is related to descriptive and exploratory research. As data collecting instruments were elaborated a structured questionnaire with closed questions and an interview s syllabus which contents are related to the research s aims. As analysis proceedings for the collected data and also to consider the qualitative approach it was chosen the Contents Analysis method from Bardin and more specifically the Categorical Analysis . Consequently, we conclude that it is deficient in production of organic information, or to produce documents that prove and control the activities that are developed within the organization is not satisfactory. The decision usually is not subsidized by organic information. Accordingly the study points out the deficiency of the perception of the importance of the organic type information as an aid to decision making and al

Encontrabilidade da Informação: atributos e recomendações para ambientes informacionais digitais

At first, this paper presents the epistemological and theoretical bases that support the inclusion of an operational concept for the findability of information in the field of Information Science. In a second moment, it defines the key attributes and recommendations for the findability of information, with a view to their understanding in a practical perspective, from the epistemological and theoretical support presented. From a theoretical, exploratory, bibliographic and documentary study, the results reveal that epistemologically the findability of information fits in Information Science in post-custodial paradigm that focuses on access to information and is significantly influenced by Information and Communication Technologies. The theoretical conclusions of this concept focus on the evolution of the Web and from the perspective of the dimensions of language, where there is as pragmatic trend, as technological development that combines the actions taken by informational and institutional individuals in digital information environments. Given that these actions turn enable or not the findability of information, these individuals can be understood as mediators. Therefore, the concept of infocommunicational mediation is the basis for the findability of information. For its application in digital information environments, were defined attributes and guidelines which should be considered in the context of Information Architecture. The attributes characterizing the concept and guidelines point at practical actions for the design and for evaluation of the findability of information. Epistemological, theoretical and practical concepts addressed underpin the called operative concept in information science and should be further explored in this scientific field.

Acessibilidade em Ambientes Informacionais Digitais

The current nature of World Wide Web (Web), which highlights the collaborative participation of users in some digital information environments, lead to development of guidelines with a focus on Inclusive Digital Information Architecture for a different audiences in multiples informational ambiences. This research proposes guidelines for a inclusive digital information environment, aiming to identify the elements of accessibility that allow the promotion of inclusion digital information, in order to highlight the references of the Architecture of Digital Information, the international recommendations and the structures representation of information (specially accessibility attributes), with the look of Information Science and New Technologies of Information and Communication. The thesis is as to the need to develop methodologies with guidelines that contemplate the elements of digital accessibility focused on the task of the user. The research problem is that actual methodologies and recommendations used for the development of digital information environments do not cover all the elements of accessibility with a focus on user needs. The proposition is to present, through a methodological approach (exploratory and descriptive), a theoretical-methodological proposal to promote elements of digital accessibility to the development of digital information environments, for users with or without special needs. The overall objective of this study is to contribute to the development of inclusive digital information environments, in perspective of union of theories, recommendations and technologies for the development of digital accessibility guidelines. In a theoretical dimension, the research covers a critical review of the specialized literature in the areas of Information Science and Computer Science and, in the applied part, the analysis and development of a proposal of guidelines for the architecture of a digital information environment with accessibility.

Análise do fígado de peixes da espécie Prochilodus lineatus de ambientes alterados, quantificada pelo Image J

Além de ser bom bioindicar a espécie Prochilodus lineatus (Characiformes, Prochilodontidae) também apresenta importância econômica, ecológica e ampla distribuição na região neotropical. A ecotoxicologia estuda a interação da química ambiental e a biota, sendo assim, este estudo teve como objetivo identificar alterações quantitativas de bile e glicogênio no fígado dos peixes, órgão responsável pelo processo de detoxificação, biotransformação e também pela reserva de nutrientes como o glicogênio e por secretar a bile. Os grupos foram separados em três tratamentos com o objetivo de comparar os danos causados aos peixes que vivem em áreas perturbadas, (como é o caso do Lago Azul – Rio Claro-SP), e os que vivem em águas com detergentes biodegradáveis diluídos, como na maioria dos nossos cursos d’água, comparados a um grupo controle (água clorada do poço artesiano da UNESP- Campus Rio Claro). Análises histológicas foram feitas com a utilização das técnicas de H-E e PAS, sendo o material coletado após sete e 20 dias de experimento, visando identificar os efeitos agudos de tais poluentes. A identificação de alterações na estrutura histológica foi realizada com o auxilio do programa ImageJ com o qual foi feita a quantificação da área ocupada pela bile e pelo glicogênio

Histoquímica de musculaturas de Astyanax altiparanae de ambientes perturbados

Atualmente, é grande a quantidade de cursos d’água continentais que se encontram contaminados por poluentes, tais como produtos químicos, metais, esgoto e detergentes biodegradáveis. Tendo em vista o fato de a musculatura possuir um papel fundamental na realização do nado em peixes, sua importância se reflete em atividades como caça, fuga, procura pelo alimento, defesa, migração, etc. Alterações na estrutura muscular de peixes, que possam vir a ocorrer devido à presença de poluentes na água trarão sérias implicações para o modo de vida destes, especialmente no caso de Astyanax altiparanae que é uma espécie pelágica e nadadora ativa. Consequentemente, tem havido uma crescente preocupação em relação aos poluentes e os efeitos que estes podem ter sobre as populações de peixes que habitam esses ambientes aquáticos poluídos, uma vez que estes constituem uma das fontes de alimento mais importantes para certas populações humanas assim como a principal fonte de renda para comunidades pesqueiras. Sendo assim, pretendeu-se por meio do presente estudo, analisar e identificar possíveis alterações na estrutura morfológica da musculatura peitoral e caudal em peixes de pequeno porte como Astyanax altiparanae, bem como analisar a ocorrência de um possível envelhecimento precoce destas, que possam ter sido causados pelos poluentes contidos na água com detergente diluído, na água do Lago Azul, Rio Claro, SP, em comparação com a água pura do poço artesiano da UNESP – Campus Rio Claro que foi clorada de acordo com o modelo requerido pela SABESP e constituiu o grupo controle. A análise foi feita com base na comparação do grupo controle com aqueles expostos aos poluentes e foram utilizadas técnicas de histologia, histoquímica e fluorescência

Amostragem da emissão de material particulado em ambientes externos

The concern of the society with regard to the pollution if becomes each bigger and necessary time. This pollution generates damage for who is in contact, as much in economic terms how much in quality of life. The particulate matter is one of the main polluting the air, being the most harmful to human health, fine particles and ultra fine (below 2.5 μm in diameter). With this, this work had as objective to mensurar the pollution of air for material particulado through samplings in an urban center, in a siderurgical industry, a conventional coal bunker and a forest fire. The equipment used for the sampling of particles had been the DataRam4 (model DR 4000) and the Impactador de Andersen, both developed by company THERMO SCIENTIFIC. The first equipment uses a system of nefelometry and the second uses a gravimetrical system of sampling. During the carried through samplings, it can be observed in some cases the difficulty in the breath, badly be and low visibility that this type of pollutant can cause. In most cases the results were disturbing. In industry, conventional coal bunker and in the forest were measured values high concentration for particles smaller diameters. Peak concentrations issued were: 40,000 μg/m³, 182,000 μg/m³ and 400,000 μg/m³ for the industry, conventional coal bunker and forest, respectively. Already in the urban centre were satisfactory results, always staying within the limit allowed by the rules in force so far in the country

Levantamento e análise de técnicas utilizadas nas operações de emergência de derramamento de óleo em ambientes costeiros e fluviais

This present paper aims to identify the main response techniques for coastal and fluvial environments and analyze impacts on the application of these techniques. The literature review allowed us to understand since the establishment of first environmental sensitivity index map, in coastal and fluvial environment, until the possible impacts generated by the application of cleanup techniques in both environments. Studies related to freshwater environment are less common compared to coastal environment. For both environments the same techniques may be employed, as well as containment and recovery, or removal of oil in the affected areas. The most serious environmental impacts generated are due to the poor choice of technique to be applied or the lack of training of the cleaning crews. In Deepwater Horizon accident, Gulf of Mexico, 2010, application of dispersants, resulted in a mixture of oil and dispersing 52 times more toxic than the oil itself. In Brazil, the technique of vegetation removal by the cleaning staff in the accident on the river Guaecá, 2004, resulted in unnecessary elimination of vegetation, increasing the volume of waste. It was concluded that the freshwater environment often suffer more impacts by applying the techniques, once is necessary to access the banks, which normally have more vegetation and organisms than shoreline of coastal environment

Utilização do protocolo anycast em ambientes virtuais distribuídos visando à escalabilidade do sistema

Distributed Virtual Environments (DVE) allow multiple users interact with a virtual world by sharing, manipulating objects. Each user has his/her own vision of this world and every changes of state of the environment are distributed among other users. Due to technological constraints, most systems for distributed virtual environments support a limited number of users. The major limitation for development of DVE scale are imposed by the communication system. As the number of users grows, the amount of bandwidth required to exchange information in real time among stations to upgrade the environment and keep it in a consistent state for all connected users. Based on this situation is proposed a framework that uses the protocol anycast in the application layer that provides a load balancing among servers in the region and aims at reducing the latency of message delivery between participants selecting the DVE server best suited for the region participant to connect to the environment

Análise comparativa de concepções de cartografia geomorfológica aplicada a ambientes litorâneos

The intense urbanization in coastal environments can cause environmental changes due to the susceptibility of these areas. It is therefore of utmost importance to understand the environmental quality of coastal area and the geomorphological features are essential to make it possible, as well as the geomorphological maps that are used as an instrument to analyze the relief. However, there is no standardization among the geomorphological mapping techniques, since the proposals vary according to the taxonomy of the relief, the adopted scale and the objective of the researcher. This paper aims to carry out geomorphological mappings of sectors of the city of Mongaguá, in São Paulo state, according to the conceptions of Verstappen and Zuidam (1975) and Gustavsson, Kolstrup and Seijmonsbergen (2006), seeking to verify the possibilities and constraints that each one can provide for environmental management. Verstappen and Zuidam’s design (1975) is a classical international bibliography proposal indicating the symbols and colors that will be used to represent the relief according to the origin shape of the geomorphological features; Gustavsson, Kolstrup and Seijmonsbergen's conception (2006) is a latest international proposal which also uses symbols and colors that can be combined to represent various forms of relief, coming from different origins. The mappings in this research are although not presented as a mainstream map, but as a cartographic representation in which the symbols are superimposed on the digital ortophoto map to provide the reader an association between symbolism and the relief represented. The result is a comparative analysis among the symbols that were used in each mapping, in which is discussed what design is the most appropriate, considering the adopted scale and the geomorphological features of the mapped area
