Ferreira, Rallyson dos Santos 05 July 2013 (has links)
Made available in DSpace on 2015-04-11T14:02:42Z (GMT). No. of bitstreams: 1 rallyson.pdf: 1971079 bytes, checksum: 1c3dd02a9f806a7c16eecd3d4f5e5863 (MD5) Previous issue date: 2013-07-05 / Constraints on Internet access, resulting from intermittent and low quality connections, have become the main obstacle to the use of Virtual Environments for Teaching and Learning in locations outside large cities, especially in challenging geographical regions like the Amazon. In this context, we present a scheme to get around these limitations, based on use of local servers and a synchronization technique that enables mediation of access to central servers, keeping local resources even when Internet connection is interrupted, performing updates when the connection is reestablished again. The proposed scheme has been developed and tested in order to evaluate its behavior in different scenarios, as well as the corresponding user perception. / Limitações do acesso à Internet, decorrentes de conexões intermitentes e de baixa qualidade, tem se tornado o principal obstáculo para o uso de Ambientes Virtuais de Ensino e Aprendizagem em localidades fora das capitais e grandes cidades, especialmente em regiões geograficamente desafiadoras como é o caso da Amazônia. Nesse contexto, é apresentado um esquema para contornar tais limitações, baseado no uso de servidores locais e de uma técnica de sincronismo que possibilita a intermediação do acesso a servidores centrais, mantendo recursos locais ainda que a conexão a Internet seja interrompida, realizando as atualizações quando tal conexão for restabelecida. O esquema proposto foi desenvolvido e testado de modo a avaliar seu comportamento em diferentes cenários, bem como a correspondente percepção do usuário.

A adoção de software livre na USP: um estudo de caso / The adoption of open source software at the University of Sao Paulo: a case study

Leila Lage Humes 30 September 2004 (has links)
O objetivo deste trabalho é estudar o processo de adoção do Software Livre na Universidade de São Paulo. É de especial interesse o estudo dos aspectos culturais e organizacionais que contribuíram para a adoção do Software Livre entre os administradores de sistemas. O estudo de adoção, não se limitou à adoção individual, mas se estendeu à adoção organizacional uma vez que a adoção de inovações tecnológicas em organizações difere de modo especial da adoção individual. A adoção organizacional aborda aspectos como a extensão do uso da inovação e, o quão profundamente o uso da tecnologia altera processos, estruturas e cultura organizacional. O fenômeno de adoção na Universidade revela-se particularmente importante por ter se tratado da adoção de uma nova tecnologia, em grande escala e bem-sucedida. Esta pesquisa estuda quais são os fatores condicionantes e os que favoreceram a adoção da nova tecnologia, bem como o contexto social e cultural desta adoção em diferentes Unidades da USP. / The objective of this work is to study the adoption of Free Software in the University of São Paulo. It is of special interest the study of the cultural and organizational aspects that contributed to the adoption of the Free Software among the systems administrators. The adoption study, was not limited to the individual adoption, but it extended to the organizational adoption once the adoption of technological innovations in organizations differs in special ways from the individual adoption. The organizational adoption examines aspects as the extension of the use of the innovation and, how deeply the use of the technology affects processes, structures and organizational culture. The adoption phenomenon in the University is particularly important for having it been a voluntary adoption of a new technology, in great scale and well succeeded. This research studies which factors restricted or favored the adoption of the new technology, as well as the social and cultural context of this adoption in different Units of USP

Design and conversational evaluation of an information technology learning environment based on self-organised-learning

Coombs, Steven John January 1996 (has links)
From 1990 to 1993 I was engaged as the Information Technology (IT) Workshop manager at Mid-Cornwall College, St. Austell. My mission during this period was to develop a new kind of IT learning environment. The main purpose was - and continues to be - to provide for mixed 'open-access’ student targets wishing to pursue generic IT activities and gain commensurate vocational qualifications. This Open-Learning (OL) environment provides on-the-job curriculum development of IT learning support systems, through a Flexible Learning (FL) management policy. An action research approach based on S-O-L provides both the methodology and technology for implementing a learning organisation. A key objective was institutional change towards the learning management policy of IT, through appropriate deployment of staffing and courseware resources to enable the practice of student centred learning. Another aim was to integrate and mix all target groups of learners together in the same domain, i. e. school leavers with adult returners for the achievement of a cost-effective, well-co-ordinated and productive learning environment. My action research applied the Centre for the Study of Human Learning's (CSHL's) ideas and tools towards the development of the IT Workshop's learning policy. I have sought to make the connection between FL delivery of the generic IT curriculum and the SOL approach towards individual and organisational learning. This came about from the link between the FL philosophy of learner-centred activity and the SOL philosophy of empowering individuals via Learning Conversations. S-O-L'Systems-7' was adopted as a conversational tool for developing the educational roles and practices of the IT Workshop. This influenced my college to make essential environmental changes to the workshop in order to develop these activities. The project also used the Personal Learning Contract (PLC) to manage and enable the 'learning-to-learn' activities of individual IT learners. With the PLC as the central tool for implementing Learning Conversations, there evolved the idea of 'Group Learning Contracts' (GLCs). This led to the practical development of 'Learning Plans' (LPs), such that IT flexible modules could be transferred to the autonomy of the learner. Evaluations from this project included sample case-study evidences of Learning Conversations obtained from individual IT case-load students. Repertory grid feedback conversations of learning experienced by individual staff members taking part in the project were also obtained. Questionnaire results from IT learners was used as another method of feedback, and conversationally evaluated using factor analysis and 'talkback' records. All the action research qualitative evidences were finally analysed using conversational techniques, leading to the overall project 'findings'.

Software Evolvability Measurement Framework during an Open Source Software Evolution

Zhang, Jianhao, Chen, Xuxiao January 2017 (has links)
Context: Software evolution comes with the increasing growth of software applications both in size and complexity. Unlike the software maintenance, software evolution addresses more on the adaption of the new fast-changing requirements. Then the term of “software evolvability” comes with its importance for evaluating the evolution status of the software. However, it is not clearly identified especially in the context of open source software (OSS). Besides the most studies are about the description of software evolvability as a quality attribute, and very few research have done on the measurement of software evolvability during the software evolution process. Objectives: In this study we perform an in-depth investigation on identification of the OSS evolvability, and figure out the appropriate metrics used for measuring the OSS evolvability. Based on that we finally proposed the open source software evolvability measurement framework (OSEM) which could be used for measuring the software evolvability generally in an OSS context. Methods: At first, we conducted a literature review by combining backward snowballing search with systematic database search. Two research questions which are RQ1 and RQ2 are proposed for helping us to retrieve the key information for building the needed framework. Then we performed a case study on VLC media player (an OSS project) to validate the processes of the proposed framework. Results: Based on literature we could explicitly identify the OSS evolvability, and figure out the differences of software evolvability addressed in OSS context and non OSS context (e.g, the traceability refers to documentation in non OSS context, however in OSS context it refers to the release version of OSS project). Besides we also fulfill the evolvability measuring method by addressing the process of prioritization of evolvability sub-characteristics. In the end we implement the OSEM framework on VLC media player and get the well documented results which are clearly presented and easy to understand. Such results could be taken by the VLC developers as an input for the design and development of the VLC. Conclusions: We conclude that the open source software measurement framework (OSEM) is applicable, based on the time we spent on the case of VLC media player it is quite fast and efficient to use such framework. The results from the conduction of this framework are documented well and very clear for OSS users/developers to follow.

Möjligheter och hinder i vidareutnyttjandet och tillgängliggörandet av öppna data i Örebro kommun / Opportunities and barriers that characterize the open data process in the municipality of Örebro

Häggblom, Jonas, Bergman, Andreas January 2016 (has links)
Det huvudsakliga syftet med denna studie är att öka förutsättningarna för Örebro kommun att bedriva ett framgångsrikt arbete med öppna data. Genom att analysera nuläget med avseende på öppna data, dels nationellt, dels inom kommunen, ämnar studien att presentera ett antal rekommenderade strategiska åtgärder som bedöms vara lämpliga för att förbättra arbetet med öppna data i Örebro kommun. Rapporten ska, förutom att fylla ett utbildande syfte internt, utgöra ett underlag för framtida beslut angående öppna data centralt inom kommunen och i kommunens förvaltningar. Två workshopar och intervjuer med interna och externa aktörer genomfördes för att identifiera utmaningar, potentiella målbilder och aktiviteter relaterade till öppna data inom Örebro kommun. Dessa analyserades utifrån tidigare forskning om öppna data i offentliga organisationer. Resultaten visar att kommunen i Örebro bör öka den organisatoriska förmågan, skapa engagemang hos medborgare och underhålla en mer målorienterad strategi för öppna data. / The release of public sector information as open data is expected to bring various benefits such as citizen participation, transparency and innovation. In recent years’ open government data has been getting more attention at various levels of government causing several frameworks and manuals to be published. These publications aim to help local governments by providing guidance on how open data efforts should be organized and implemented in practice and a common to these reports is that they contain general descriptions and guidelines that are addressed to all public organizations working with open data. This demands that the proposed practices must be customized when adapted by a specific organization. The municipality of Örebro has an ongoing commitment to open data. Since the interest in open data started to take off in Sweden, the municipality has periodically released new open data sets and on three occasions conducted hackathons with an open data theme. However, the recent introduction of a new municipal management, as well as the loss of an open data key figure, has impeded the continued work with open data in Örebro. Therefore, there is reason to examine what measures should be taken to improve the efforts of open data release in the municipality. In this study interviews and workshops were conducted to identify barriers, goals and activities related to open data in order to bring forward empirically supported recommendations that help the organization to overcome barriers and work towards a more streamlined open data process. The results suggest that the municipality in Örebro should make efforts to increase organizational capabilities, nurture citizen engagement and support a more goal-oriented strategy for open data.

Open Source Business Models / Affärmodeller för öppen källkod

Nilsson, Mats January 2002 (has links)
This thesis is describing a business strategy of how to license a software product. The licenses discussed in this thesis are called open source licenses. The open source licenses have gained much attention lately by companies such as Microsoft, IBM, and Sun Microsystems. The reason for this is that some products considered being open source software are very widely used. These products include the most popular web server, the Apache web server, with more than 60% market share. 25% of the installed operating systems that are running Apache and other web servers are installed with Linux as operating system, which is also considered as open source software. These are only two examples of popular products that are considered as open source software products. These products are choices for many people and companies when choosing software to use, for example NASA. Open source licenses are called open in the way that the software is shipped not only in binary form, but also with the source code that can be modified and recompiled to suit the buyer’s need better. Apache web server and the Linux operating system are free for download, install, run and modify to suit your needs. In this thesis I will discuss whether these licenses can increase the chance of developing a successful product or not, in terms of market shares. / Affärsmodeller kring öppen källkod diskuteras i denna magisteruppats. Det finns ett flertal programvaror byggd på öppen källkod som kan betraktas som framgångsrika om man avser antal användare eller hur stora marknadsandelar produkterna har. Diskussionen i magister uppsatsen kretsar därför om man kan öka sina chanser att utveckla framgångsrika produkter genom att använda sig av öppen källkod främst ur ett företags perspektiv som har vinstintresse. / Mats Nilsson Kabelgatan 13D 414 57 Göteborg

Why Selecting an Open Source ERP over Proprietary ERP? : A focus on SMEs and Suppliers perspective

Huq, Nasimul, Shah, Syed Mushtaq Ali January 2010 (has links)
Introduction: Open Source ERP is considered as a viable alternative of proprietary ERP paradigm. Open Source ERP is getting more and more acceptance among Small and Medium Sized Enterprises (SMEs) recently. Majority of Proprietary ERP vendors are changing their strategy nowadays and extend their focus on SMEs, even though SMEs are not that interested in Proprietary ERP systems. The factors that may motivate SMEs to select an Open Source ERP over proprietary ERP are not identified empirically in previous researches. Few researches raised the issue of cost and thus proposed that Open Source ERP is appropriate for SMEs. The other factors than cost involved in the selection process are yet to investigate empirically. Purpose: The overall purpose of this thesis work is to contribute in knowledge domain of Open Source ERP. Open Source ERP is an emergent area but it has the potential to attract many organizations to implement this kind of ERP Systems. The issue under investigation throughout this research will be the selection process of Open Source ERP in Small and Medium Sized Enterprises (SMEs). The focus will be to identify mutually most important factors, from the perspective of SMEs and Suppliers that may motivate the Small and Medium Sized Enterprises (SMEs) to select OS ERP. Method: Data obtained from the respondents is quantified in the research. Information gathered from the SMEs who have implemented Open Source ERP and from the Suppliers through web based survey. Two separate questionnaires comprised of various questions related to different factors in selecting of Open Source ERP solutions were made and sent to both SMEs and Suppliers of Open Source ERP. Opinion from an Open Source ERP expert is obtained regarding different factors motivate SMEs to select Open Source ERP. The results obtained from respondents through empirical findings were analyzed thereafter. Conclusions: SMEs were investigated regarding the importance of various rationales when they were selecting Open Source ERP solutions. The degree of importance of various factors in selection process might be diverse from organization to organization. It might be dependent on the size, geographical location of the organization or many other issues. Despite all this, there might be some common factors that may be always considered as foremost factors which influence SMEs to select an Open Source ERP over proprietary ERP.

The Emergence of Crowdsourcing and Open-Source Models in Drug Development / The Emergence of Crowdsourcing and Open-Source Models in Drug Development

Evaldsson, Johan, Ljungdahl, Thomas, Suter, Fredrik January 2012 (has links)
Contemporary cases of crowdsourcing (CS) and open source development (OS) related to drug development have been selected and studied. Contemporary examples of CS/OS from within and outside of the pharmaceutical industries have been presented to give a background and suggest possible benefits and problems. The main criteria for selection have been that the case must seek to advance drug development and must use crowdsourcing or open source as a mechanism. The cases found in our search show a large diversity in terms of application, usage, and possible implications for the pharmaceutical industry. We found that crowdsourcing within a scientific problem context produced good results, but that open source initiatives were either poorly financed and not successful or focused on neglected diseases made possible through strong backing by non-profit organizations. An analysis of which the pharmaceutical companies where that showed activity on the platforms identified R&D-intensive and biotech companies as the most active. Contract research organizations (CROs) and generics manufacturers (GMs) showed almost complete absence. We argue that GMs are not likely to be interested in this kind of R&D, but CROs are an untapped resource. Finally we propose a hypothetical model that takes into account all the findings from our study and the literature. This model is based on a limited type of open source with a limited number of partners making use of the untapped CRO resource through crowdsourcing. / Ett antal pågående fall av samverkans-modellen crowdsourcing (CS) samt fenomenet av ”öppen-innovation”, open-innovation (OI) har studerats i kontexten läkemedelsutveckling. I denna fall-studien presenteras ett antal fall där CS och OI används både inom och utom läkemedelsindustrin. Detta har gjorts för att skapa en bättre förståelse för fenomenen samt att tydliggöra problem och att belysa fördela med öppen-innovation och olika typer av samverkans-modeller. Huvudkriteriet för utvalen av fall har varit ett avancerat stadium i läkemedelsutvecklingen samt att något av de två verktygen OI eller CS används aktivt i utvecklingsarbetet. Fall-studien klargör en tydlig differens mellan olika applikations-typer och hur man i verkligheten implementerar dessa verktyg i forskningsarbete. Vår fall-studie indikerar goda resultat då man använder samverkans-modellen CS inom forskningsarbete, men att ”öppen-innovation” OI inte gav samma goda resultat då immateriella mekanismer bromsar öppenheten i läkemedelsindustrin. Inom läkemedels-utvecklingen för Negleted Diseases fann vi däremot en större aktivitet vilken grundar sig på icke-vinst-drivande aktörers intressen. Genom en analys av aktörer inom läkemedelsindustrin har vi kunna framtyda att forsknings-och utveckligns-företag samt Biotech som de som mest ser och utnyttjar potentiallen i CS och OI. Contract research organizations (CROs) och Generics Manufacturers (GMs) är nästan uteslutande frånvarande i resultaten från vår analys. Våra resultat visar att GM-företagen inte har mycket intresse av varken CS eller OI, men att för CRO-företagen finns det vinning i att utnyttja dessa resurser. Slutligen förespråkar vi en fortsatt forskning i ämnet baserat på fall-studien för att kunna ta fram en hypotetisk-CS modell, vilken skulle baseras på ett begränsat antal av samarbetspartners vars potentiella vinning skulle visas genom utnyttjandet av samverkans-modellen CS. / Johan Evaldsson +733-706822

La notion de « qualité » des publications dans l’évaluation de la recherche et des chercheurs en sciences humaines et sociales: Le potentiel de l’Open Access pour dépasser le paradoxe des prescriptions en matière de qualité et l’ambivalence de leur perception par les chercheurs en sciences de la communication

Vanholsbeeck, Marc 26 February 2016 (has links)
1. Un premier apport de notre travail consiste à proposer un cadre théorique, analytique et conceptuel original, permettant d'approcher la notion de qualité des publications en SHS (sciences humaines et sociales) et en sciences de la communication de façon à la fois holistique et dynamique, en tant qu'elle fait l'objet de descriptions et de jugements multiples, émis par une diversité de parties prenantes, au sein et en dehors des milieux académiques. Pour ce faire, il s'agira de considérer la qualité dans ses différentes dimensions constitutives (approche holistique) tout en l'inscrivant dans le cadre d'évolutions tendancielles en matière de publication scientifique (approche dynamique) et en tenant compte de la qualité telle qu'elle est prescrite, souhaitée et mise en oeuvre par les différentes parties prenantes (chercheurs et entités prescriptrices, aux niveaux politique et managérial). En croisant de façon systématique ces trois approches - approche multidimensionnelle, rapport aux prescrits et aux souhaits, et étude des évolutions tendancielles -, il s’avérera possible d'évaluer l'incidence des différentes tendances en matière de publication scientifique – i.e. tendances à la massification, à l'internationalisation, à l' « exotérisation » (i.e. à l'ouverture vers le monde extérieur, au-delà des pairs), à la « gestionnarisation » (i.e. à l'usage des publications dans la gestion dela recherche et des chercheurs, en particulier en situation d'évaluation), à la commercialisation et à l' « enlignement » (i.e. à la mise en ligne, sur Internet) – ainsi que des prescriptions managériales et politiques qui les initient, les stimulent ou les prolongent à des degrés divers, sur la qualité de l'activité même de publier, et sur celle des différents types génériques et spécifiques d'objets publiés.2. En appliquant cette triple approche aux SHS et, plus particulièrement, au cas des sciences de la communication, nous montrerons comment la plupart des évolutions tendancielles qui sont discutées ici ainsi que des prescrits politiques et managériaux qui y affèrent aboutissent à valoriser principalement, en situation d'évaluation de la recherche et des chercheurs, la publication d'un grand nombre d'articles dans des revues savantes internationales de premier plan, destinés avant tout aux pairs, et à dévaloriser les publications, ouvertes à des publics plus locaux, rédigées en langue vernaculaire, ou qui se consacreraient à la résolution de problèmes de société. En particulier, à la faveur de la tendance à la « gestionnarisation » des publications, l'article de revue savante internationale de premier plan, ainsi que les citations qui lui sont faites par les seuls pairs, sont posés en indicateurs de performance de tout premier plan, « fixant » ainsi les pratiques de recherche et de publication des chercheurs. Cette « fixion » sera d'autant plus marquée que les indicateurs bibliométriques, à l'échelon national, seront intégrés à des processus de financement public de la recherche fondés sur les performances, et que, à l'échelon international, les indicateurs joueront un rôle prépondérant dans l'établissement des rankings des universités ainsi que des benchmarks des systèmes nationaux et régionaux de recherche. Pour autant, des prescriptions politiques sont également édictées, principalement au niveau européen, dans l'optique de la mise en oeuvre, au sein de l'Espace européen de la recherche et, dans une moindre mesure, de l'Espace européen de l'enseignement supérieur, d'une économie de la connaissance compétitive à l'échelon global et, plus particulièrement, d'un « mode 2 » de production des connaissances, qui insistent sur l'importance de davantage valoriser les résultats de la recherche, interdisciplinaire et coopérative, auprès de parties prenantes extra-académiques. En résulte une relation paradoxale entre la tendance à l'exotérisation de la recherche et des publications, et les prescrits de gestionnarisation des publications, ainsi qu'entre les prescriptions qui les sous-tendent respectivement.3. Or l'enquête que nous avons menée auprès des membres de trois sociétés savantes internationales en sciences de la communication montre combien les chercheurs de cette discipline ont désormais bien intégré les critères de qualité promus par les prescrits politiques et managériaux soutenant l'instauration d'une nouvelle « culture de la publication », à la croisée des tendances à la massification, à l'internationalisation et à la gestionnarisation des publications. Pour autant, des entretiens approfondis menés auprès de chercheurs en sciences de la communication actifs en Belgique francophone et néerlandophone n'en révèlent pas moins que ces derniers développent une attitude foncièrement ambivalente envers la culture du « publish or perish » et à l'égard de prescriptions qui sur-valorisent les revues savantes internationales de premier plan, en situation d'évaluation de la recherche et des chercheurs. D'une part, en effet, les chercheurs avec qui nous nous sommes entretenus estiment que la nouvelle culture de la publication joue un rôle bénéfique dans la professionnalisation et dans le développement d'une culture véritablement scientifique dans les sciences de la communication. Partant, la plupart d'entre eux développent des stratégies visant à aligner leurs pratiques de publication sur les prescrits. D'autre part, plusieurs répondants n'en regrettent pas moins le caractère réducteur de la survalorisation des revues savantes internationales de premier plan dans l'évaluation, et souhaitent qu'une plus grande diversité de types de publication soit prise en compte par les évaluateurs. Afin de concilier « qualité prescrite » et « qualité souhaitée » dans la qualité de leur activité effective de publication et dans celle des objets effectivement publiés (« qualité réelle »), il arrive dès lors à ces chercheurs de « bricoler » avec les prescriptions. Par ailleurs, la plupart des répondants, davantage cependant en FédérationWallonie-Bruxelles qu'en Flandre, où le financement public de la recherche est d'ores et déjà fondé en partie sur des indicateurs bibliométriques et revue-métriques, regrettent le manque d'explicite dans la formulation des prescriptions – ces dernières prenant régulièrement la forme de « scripts » plus indirects et/ou implicites, plutôt que de normes et de règles stricto sensu –, ainsi que l'absence de seuil quantitatif minimal à atteindre.4. Il nous semble par conséquent, dans une optique plus normative, que le dépôt systématique des différents types de publication produits par les chercheurs en SHS et en sciences de la communication sur des répertoires numériques institutionnels (Open Access Green) serait de nature à (contribuer à) résoudre le paradoxe des prescriptions en matière de « qualité prescrite », ainsi que l'ambivalence des perceptions des chercheurs en matière de « qualité souhaitée ». En effet, le dépôt des publications sur des répertoires institutionnels ouvre des opportunités inédites de renouveler la conversation savante qui se structure autour des objets publiés, au sein de la communauté argumentative (Kommunikationsgemeinschaft) des pairs, par le biais notamment de la revue par les pairs ouverte et grâce à la possibilité de commenter ad libitum les publications disséminées en Open Access. mais également en rendant les résultats de la recherche aisément accessibles et ré-utilisables par des parties prenantes extra-académiques. Les opportunités liées au dépôt des publications sur des répertoires Open Access (Green), en termes de qualité tant épistémique que pragmatiquede ces dernières, seront d'autant plus fécondes que le dépôt des travaux sur les répertoires institutionnels s'articulera à l'usage, par le chercheur, des instruments idoines, génériques ou dédiés, du Web participatif (Wikis, blogues, micro-blogues, réseaux sociaux, outils de partage de signets et de listes bibliographiques). Par ailleurs, les dépôts numériques fonctionnent désormais en tant qu'« outils de transparence », susceptibles de donner davantage de visibilité à des productions de recherche et des types de publication diversifiés. En situation d'évaluation de la recherche et des chercheurs, le recours aux dépôts institutionnels - pour autant qu'un mandat prescrive le dépôt de tous les travaux produits par les chercheurs de l'institution – permettrait aux évaluateurs de fonder leur jugement sur une gamme plus large et plus représentative de types de publication et de formes de communication en SHS et en sciences de la communication. De plus, grâce à la dissémination en Open Access, en conjonction avec l'usage d'une diversité d'outils du Web participatif, il devient mieux possible de soumettre les différents types de publication archivés et publiés en libre accès à des indicateurs de performance eux-mêmes diversifiés – bibliométriques, mais également « webométriques » et « altmétriques » -, fondés sur les articles plutôt que sur les revues et mieux adaptés à la diversité de leurs impacts, tant au sein qu'en dehors du cercle des pairs.5. Partant, l'Open Access (Green) nous apparaît in fine comme étant doté d'un potentiel important, en matière d'intégration de la recherche et des chercheurs en SHS et en sciences de la communication à la mise en place – au-delà d'une économie de la connaissance - d'une véritable société de la connaissance, ainsi qu'aux processus d'innovation techno-industrielle, sociale et intellectuelle qui la sous-tendent. / Doctorat en Information et communication / info:eu-repo/semantics/nonPublished

POTENCIALIDADES DO USO DE UM SISTEMA WEBGIS NA PECUÁRIA DE PRECISÃO: ESTUDO DE CASO EMBRAPA PECUÁRIA SUL / POTENTIAL USE OF A WEBGIS SYSTEM IN PRECISION LIVESTOCK: CASE STUDY EMBRAPA LIVESTOCK SOUTH

Rocha, Danilo Serra da 12 August 2014 (has links)
Precision farming and livestock are topics of spatial nature, so commonly use the Geographic Information Systems (GIS) because they present themselves like excellent management tools. GIS allow management spatial data and its interconnection with alphanumeric attributes, performing complex analysis and the possibility to simulate various scenarios in order to provide an effective decision-making. Recent developments in internet technologies have contributed to access, publication, distribution and exploitation of geographic information. The use of the internet distributed GIS (WebGIS) using free software, can be a proper solution since GIS places accessible to user functionalities, through a simple browser, without the need for large investments in relation to software or even in specialized technical training . Therefore, this Master s Dissertation developed a WebGIS using free software that provides geographic and alphanumeric information layers that are under the responsibility of Embrapa South Livestock, allowing registered users to view and conducting research and spatial analysis operations. / A agricultura e a pecuária de precisão são temas de natureza espacial, por isso utilizam comumente os Sistemas de Informação Geográfica (SIG) pois estes apresentam-se como excelentes ferramentas de gestão. Os SIG permitem o gerenciamento de dados espaciais e sua interligação com atributos alfanuméricos, a realização de análises complexas e a possibilidade de simular diversos cenários de modo a propiciar uma tomada de decisão eficaz. Os recentes desenvolvimentos em tecnologias da internet têm contribuído para o acesso, publicação, exploração e distribuição da Informação Geográfica. A utilização de SIG distribuídos na internet (WebGIS), utilizando softwares livre, pode ser uma solução adequada visto que coloca funcionalidades de SIG ao alcance de usuários, através de um simples browser, sem necessidade de grandes investimentos em relação a softwares ou mesmo em formação técnica especializada. Assim, na presente dissertação, desenvolveu-se um WebGIS, utilizando softwares livres, que disponibiliza informações geográficas e alfanuméricas de camadas que estão sob a responsabilidade da Embrapa Pecuária Sul, permitindo aos usuários cadastrados a visualização e a realização de pesquisas e operações de análise espacial.
