Facilitating collaboration : exploring a socio-technical approach to the design of a collaboratory for Library and Information Science

Lassi, Monica January 2014 (has links)
The thesis explores the potential of one way of facilitating and stimulating collaboration in Library and Information Science (LIS), through a specific scientific collaboration activity: creating, sharing and reusing data collection instruments, such as interview guides, questionnaires, and observation protocols. The four studies reported in the thesis can be read as a linear narrative, each study building on the previous and contributing to the following ones. Together the four studies describe the process exploring social and contextual aspects of LIS; developing requirements and designing a working prototype collaboratory; and evaluating how the prototype collaboratory was perceived by LIS professionals. Overall, the results show that whereas the benefits of an LIS collaboratory reported by the study participants focused on the greater good for LIS, the challenges reported focused on the individuals’ perspectives. Hence, a tension exists between supporting the greater good, and challenges for individuals concerning sharing and reusing data collection instruments in an LIS collaboratory. The thesis emphasizes the implications for the LIS discipline when new ways of working with data collection instruments would be introduced; the implications of addressing needs of a diverse target audience; and the implications for further design iterations of an LIS collaboratory, including rewarding contributions, and ensuring quality content in a collaboratory. / <p>Academic dissertation for the Degree of Doctor of Philosophy in Library and Information Science at the University of Gothenburg and the University of Borås to be publicly defended on Wednesday 11 June 2014 at 13.15 in lecture room E310, University of Borås, Allégatan 1, Borås</p>

No. of bitstreams: 1 Adriano Cesar Braz Caldeira.pdf: 1061457 bytes, checksum: ae0cab21c651ef05d3d78ff6ec83675f (MD5) Previous issue date: 2008-08-12 / This essay has as purpose a legal institution that is subject of frequent controversies amongst law scholars and case law, to wit, lis pendens between collective actions, and between the latter and individual ones. In spite of the existence of excellent works mentioned in the bibliography hereof on lis pendens among such kinds of actions, they are very limited as regards individual actions. We understood that dealing with collective action complying with merely and strictly those rules applicable to individual lawsuits is a mistake, with all due respect. This paper aims at analyzing which are those actions that may be considered as collective indeed. Thus, Civil Public Action, Popular Action, Collective Mandamus, Collective Injunction Order, Direct Unconstitutionality Action, Action for Declaration of Constitutionality, Argumentation of a Basic Principle Breach, Action against Dishonesty in Administration. This paper carries out a preliminary analysis of issues like legitimacy, the very concept of party, the internal formation of lawsuits (parties, claim, and cause of action), the effects resulting from the decision, so that the main issue may be eventually dealt with. It is concluded that there are two criteria of setting lis pendens between those institutions: one of them, traditional, characterized whenever the same internal elements of a lawsuit are present; another, that takes into account the claim s identity, although some internal elements may be different. This thesis points out further contrarily from what is observed in lis pendens for individual actions that in collective actions the lawsuit should not be dismissed, but rather gathered together, by virtue of a possible higher extent thereof, as it can occur with the cause of action, and as a way of preventing the other action s holder s free access to the Judiciary / O trabalho, que ora se apresenta, tem por objeto tratar de uma figura, objeto de constantes polêmicas na doutrina e na jurisprudência, qual seja, a litispendência entre as demandas coletivas e entre estas e as individuais. Nada obstante tenhamos na bibliografia excelentes obras, cuidando da figura da litispendência entre estas espécies de demandas, fazem-no, salvo raras exceções, restritivamente com relação ao processo individual. Entendemos que tratar do processo coletivo com olhos fixos nas regras de processo individual, data maxima venia, configura um erro. O trabalho procura analisar quais são as demandas verdadeiramente coletivas e, assim, encontramos a Ação Civil Pública, Ação Popular, Mandado de Segurança Coletivo, Mandado de Injunção Coletivo, Ação Direta de Inconstitucionalidade, Ação Declaratória de Constitucionalidade, Argüição de Descumprimento de Preceito Fundamental, Ação de Improbidade Administrativa. Procura analisar de modo prévio as questões da legitimidade, do conceito de parte, da formação interna das demandas (partes, pedido e causa de pedir), os efeitos decorrentes da decisão, para que, ao final, possa tratar do tema principal. Conclui que existem dois critérios de configuração da litispendência entre estas figuras: um, tradicional, que se verifica quando da presença dos mesmos elementos internos da demanda; outro que leva em consideração a identidade de pretensão, ainda que distintos alguns dos elementos internos. Observa ainda que, diferentemente do que se verifica na litispendência entre demandas individuais, entre as demandas coletivas, o processo não deve ser extinto, mas reunido, em razão da eventual amplitude, como pode ocorrer com a causa de pedir, e como forma de negar ao titular da outra demanda a liberdade do acesso à justiça

Aplicação da amostragem por interceptação por linha no levantamento de Floresta Estacional Semidecidual / Application of the line interception sampling in semideciduous forest survey

Arikawa, Eimi 22 August 2016 (has links)
A floresta é construída por manchas de diferentes idades, cujos indivíduos têm estrutura semelhantes e idade aproximada, formando um mosaico florestal, relatando a ideia de padrão e processo. Portanto o conjunto de árvores com mesmo padrão de estrutura que pode ser definida e descritível é chamada de ecounidade ou arvoredo natural. Realizar o levantamento de florestas naturais é um desafio por conta da diversidade e complexidade natural do sistema. O Método de Amostragem por Interceptação por Linhas é um método versátil onde linhas são lançadas na área e todo elemento interceptado é amostrado. As estimativas têm como base a probabilidade que o objeto é interceptado, e qualquer atributo do arvoredo pode ser usado como variável aleatória. Neste estudo são amostrados os arvoredos naturais, e as variáveis de interesse são: diâmetro à altura do peito (DAP), número de indivíduos, área basal e volume. Primeiramente foram determinadas características de identificação dos arvoredos principalmente com base nos elementos: densidade de árvores, densidade de sub-bosque, cipós lenhosos e herbáceos, sendo que estas características eram avaliadas em conjunto. Na E. E. de Caetetus, onde a floresta é mais conservada, a identificação foi fácil, sendo que as características seguiam os padrões, porém, em Mombuca, a identificação foi mais difícil, provavelmente devido ao constante e intenso distúrbio antrópico, que não tem padrão. Por isto em áreas mais degradadas é necessário identificar outras características que possam auxiliar na descrição dos tipos de arvoredos. Foram tomadas 6 medidas das distâncias do centro do arvoredo até o seu limite, com 60o entre elas, a fim obter o formato e dimensões. Todas as árvores contidas neste hexágono tiveram seu DAP medido. Ao nível de arvoredo, as análises sobre DAP médio, e DAP máximo indicam conservação dos processos ecológicos na E. E. de Caetetus, porém em Mombuca o padrão é diferente. Há desordem do DAP médio dos arvoredos, de acordo com o tipo de arvoredo que foi classificado, e portanto, com o estágio sucessional que se encontra, e há descontinuidade da distribuição diamétrica. Estes dados encontrados podem ser um indicativo de degradação ou baixa conservação da floresta estudada. O estimador usado foi o diâmetro médio do arvoredo, o qual foi estimado o número de indivíduos, área basal e volume por hectare. Os valores encontrados foram próximos a de outro trabalho em mesmo tipo de vegetação e os dados da E. E. de Caetetus foram comparados com os valores do censo realizado nas parcelas permanentes, os quais foram próximos. Pelo fato de este trabalho ter sido uma amostragem piloto para testar o método, o número de unidades de amostras foi baixo, comprometendo as análises, portanto para os próximos estudos, é recomendado que a intensidade amostral seja maior. Pela eficácia da coleta de dados em campo, e a utilização da amostragem por interceptação de linha, foi possível obter alguns resultados que sugerem que o método é promissor, sendo adequado para levantamentos de florestas naturais. É necessária uma refinação do método, além do teste em outras fisionomias, para que as estimativas possam ser mais precisas, com amostras maiores. / The forest is built by patches of different ages, whose individuals have similar structure and approximate age , forming a forest mosaic, reporting standard idea and process. Therefore the set of trees with the same pattern structure that can be defined and describable are called natural ecounits or tree clusters. To survey natural forest is a challenge because of the diversity and complexity of the natural system. The Line Interception Sampling Method is a versatile method where lines are thrown in the area and all intercepted element is sampled. The estimates are based on the probability that the object is intercepted, and any trees attribute can be used as a random variable. In this study the natural tree clusters were sampled, and the variables of interest were: diameter at breast height (DBH), number of individuals, basal area and volume. First it was determined the identification characteristics of the tree clusters, that were mainly based on elements, as density of trees, understory density, herbaceous and woody vines. These characteristics were evaluated together. In E. E. Caetetus, where the forest is more conserved, identification was easy, and the characteristics of the standards were followed, but in Mombuca identification was difficult probably due to the constant and intense anthropogenic disturbances that have no standard. So, in the most degraded areas it is necessary to identify other characteristics that may assist in the description of the types of tree clusters. 6 were distance measures were taken from the tree cluster center to its limit, with 60° between them, in order to obtain its shape and dimensions. All trees in this hexagon had their DAP measured. At tree cluster level, the analysis of average DAP, maximum DAP indicate conservation of ecological processes in E. E. Caetetus, but in Mombuca the pattern is different. There is DAP average disorder among the tree clusters, according to the type of trees that were classified, and therefore to the successional stage it is in, and there is discontinuity of the diametric distribution. These data can be found as indication of degradation or low conservation of forest studied. The estimator used was the average diameter of the tree cluster, from which it was estimated the number of individuals, basal area and volume per hectare. The values were close to other work in the same type of vegetation and the data of E. E. Caetetus was compared with the values of the census conducted in permanent plots, which were close. Because of this work was a pilot sampling to test the method, the number of sampling units was low, compromising the analysis, so for the next studies it is already recommended that the sampling intensity is greater. The effectiveness of data gathering in the field, and the use of sampling line interception made it possible to get some results suggesting that the method is promising and is suitable for natural forest surveys. It is necessary to refine the method, and calibration in other physiognomies so that the estimates would be more accurate.
