An investigation into the use of social network sites to support project communications

Harvey, Natalie January 2010 (has links)
System deployment projects are extremely complex and with more and more organisations now choosing to configure and deploy off-the-shelf systems, the project teams are presented with new challenges. The aim of this study was to gain an understanding of the issues faced during such configuration and deployment projects and see if support could be provided. A year long observational study of one of these projects was carried. While it was initially assumed that it would be technical issues related to the system’s configuration that would be the primary problems, the study revealed communication issues to be at the heart of a large number of the issues. Online social networks such as Facebook are extremely popular, allowing users to stay in touch with large numbers of distributed people. Private social network sites were applied to projects to see if they could replicate the benefits the sites provide and support project communications. A social network site was created for both a distributed research project and an administrative systems project and their use observed. Statistical data on the use of the sites and qualitative feedback from users is presented to assess the viability of the approach. The experiments showed social network sites to have many benefits when used as a complementary mechanism to traditional channels for project communications. It is clear however, that social network sites cannot solve all the problems projects may encounter. If the use of a site is to be a success it is vital it gains a critical mass of users. The approach taken to the site’s configuration and introduction will be hugely influential in its success. In order to choose the right approach a clear understanding of what the project’s communication needs are and the possible uses of the site is needed. A process of configuration and development with a small group of potential users is recommended to ensure it is as user friendly as possible before going live to a large user base.

Operacionalidade de redes geodésicas de apoio ao cadastro rural / Functionality of reference geodetic networks to rural cadastre

Souza, Genival Corrêa de 29 October 2004 (has links)
Nos últimos anos, tem sido evidente a importância dos sistemas de cadastro territorial. Isso tem ocorrido, principalmente, devido à sua crescente função no desenvolvimento econômico, e no gerenciamento ambiental. Dentre os elementos fundamentais de um sistema cadastral, destaca-se o custo do cadastramento, o qual deve ser compatível com a utilidade de cada imóvel cadastrado. Nesse contexto, e considerando as exigências da Lei 10.267, este trabalho demonstra que certas características das redes geodésicas de apoio ao cadastro influenciam determinantemente nos custos do cadastramento dos imóveis rurais e, portanto, que tais características devem ser cuidadosamente consideradas quando da implantação e manutenção de sistemas cadastrais. É introduzido o conceito de operacionalidade, como mais um parâmetro a ser maximizado na elaboração de um novo projeto, ou na análise de uma rede já existente. A determinação dos parâmetros de operacionalidade fundamentou-se na identificação e atribuição de \"pesos\" às características dos vértices, através de uma pesquisa entre profissionais e estudiosos da área, e mediante o envio de dezenas de questionários. Dessa pesquisa foi possível inferir que os atributos relacionados ao acesso, monumentação do vértice, uso de receptores GPS e uso por estação total, têm o mesmo peso, sendo que uma importância menor foi atribuída às facilidades logísticas locais. Ficou demonstrado também que, além dos atributos dos vértices, a densidade da rede também influencia a operacionalidade. Utilizando-se de simulações, e tendo como referência uma região piloto, selecionada dentro do Estado de São Paulo, quantificou-se a influência da densidade que, agregada às características dos vértices, permitiu desenvolver um método para obtenção de um indicador numérico da operacionalidade, o qual denominou-se Índice de Operacionalidade. O trabalho permitiu, ainda, separar as redes em 4 classes de operacionalidade, de acordo com a expectativa de dispêndio de tempo para a implantação de uma base topográfica de apoio aos levantamentos cadastrais de imóveis rurais. / In the last few years, it has been noticeable the importance of territorial cadastre systems. This is happening mainly because of its increasing function in economic development, and in environmental managing. Among the fundamental elements of a cadastre system, the cadastral cost, which must be compatible with the utility of each cadastred land parcel, is emphasized. In this context, and considering the 10.267 Law demands, the present study shows that certain characteristics of reference geodetic networks have influence in a determinant way in the costs of rural cadastre, and for that, these characteristics must be carefully considered when implementing and maintaining cadastral systems. The functionality concept was introduced as one more parameter to be maximized when elaborating a new project, or in the analysis of an already existing network. The determination of functionality elements was based in the identification and attribution of \"weighs\" to the network stations characteristics through an investigation by mailing questionnaires to surveyors and researchers. From this investigation, it was possible to infer that the attributes related to the network stations access, monuments, functionality for GPS and total station surveys have the same weigh, however local logistics facilities have been attributed with less importance. It was also demonstrated that, besides the network stations attributes, the network density also influences the functionality. Using simulations, and having as reference a pilot area, selected within São Paulo state, it was quantified the density influence that, together with the network stations characteristics, allowed the development of a method to obtain a numerical indicator of the functionality, which was called Functionality Index. This study also permitted to separate the networks into 4 classes of functionality, according to the time wasting expectation to establish 2 control points to support cadastral surveys.
