Previous research has demonstrated that a network model of destination value creation (i.e. the Destination Value System model) based on the flows of travelers within a destination can be used to estimate and predict individual attractions’ marginal contributions to total visitor expenditures. While development to date of the Destination Value System (DVS) has focused on the value created from dyadic relationships within the destination network, previous research supports the proposition that system-level network structures significantly influence the total value created within a destination. This study, therefore, builds upon previous DVS research in order to determine the relationships between system-level network structures and total value creation within a destination. To answer this question econometric analysis of panel data covering 43 Florida destinations over the period from 2007 to 2015 was conducted. The panel data was created utilizing volunteered geographic information (VGI) obtained from 4.6 million photographs shared on Flickr. Results of econometric analysis indicate that both seasonal effects and DVS network structures have statistically significant relationships with total tourism-related sales within a destination. Specifically, network density, network out-degree centralization, and network global clustering coefficient are found to have negative and statistically significant effects on destination value creation, while network in-degree centralization, network betweenness centralization, and network subcommunity count are found to have positive and statistically significant effects. Quarterly seasonality is also found to have dynamic and statistically significant effects on total tourism-related sales within a destination. Based on the network structures of destinations and total tourism related sales within destinations, this study also uses k-means cluster analysis to classify tourism destinations into a taxonomy of six different system types (Exploration, Involvement, Development I, Development II, Consolidation, and Stars). This taxonomy of DVS types is found to correspond to Butler’s (1980) conceptualization of the destination life cycle, and additional data visualization and exploration based on the DVS taxonomy finds distinct characteristics in destination structure, dynamics, evolution, and performance that may be useful for benchmarking. Additionally, this study assesses the quality of VGI data for tourism related research by comparing DVS network structures based on Flickr data and visitor intercept survey data. Support for the use of VGI data is found, provided that thousands of observations are available for analysis. When fewer observations are available, aggregation techniques are recommended in order to improve the quality of overall destination network system quantification. This research makes important contributions to both the academic literature and the practical management of destinations by demonstrating that DVS network structures significantly influence the economic value created within the destination, and thus suggests that a strategic network management approach is needed for the governance of competitive destinations. As a result, this study provides a strong foundation for the DVS model and future research in the areas of destination resiliency, “smarter” destination management, and tourism experience design.

Testo completoThe emergence and subsequent uptake of Information and Communication Technologies has transformed the research processes in universities and research institutions across the globe. One indelible impact of Information and Communication Technologies on the research process is the increased generation of research data in digital format. This study investigated how research data has been generated, organised, shared, stored, preserved, accessed and re-used in Malawian public universities with a view to proposing a framework for research data management in universities in Malawi. The objectives of the study were: to determine research data creation, sharing and re-use practices in public universities in Malawi; to investigate research data preservation practices in public universities in Malawi; to investigate the competencies that librarians and researchers need to effectively manage research data; and to find out the challenges that affect the management of research data in public universities in Malawi. Apart from being guided by the Community Capability Model Framework (Lyon, Ball, Duke & Day, 2011) and Data Curation Centre Lifecycle Model (Higgins, 2008), the study was inspired by the pragmatic school of thought which is the basis for a mixed methods research enabling the collection of quantitative and qualitative data from two purposively selected universities. A census was used to identify researchers and librarians while purposive sampling was used to identify directors of research. Questionnaires were used to collect mostly quantitative and some qualitative data from 36 librarians and 187 researchers while interviews were conducted with directors of research. The Statistical Package for the Social Sciences was used to analyse the quantitative data by producing percentages, means, independent samples ttest and one-way analysis of variance. Thematic analysis was used to analyse the qualitative data.

Testo completoDigital transformationen lyfts som ett sätt att lösa många av de problem och utmaningar som den offentliga sektorn står inför gällande kostnadsutveckling och ökade krav på bättre samhällsservice. Öppna data är en sådan strategisk resurs som är nödvändig för att dennautveckling ska ske och kommunsektorn samlar på sig information som skulle kunna publiceras för att skapa värden i många led. Dels menar tidigare forskning att ekonomiska värden kan genereras genom nya innovativa tjänster och produktivitetsökningar, men även sociala värden som ökad medborgardelaktighet och transparens. Men trots tidigare försök att stimulera öppna data, ligger Sverige långt efter jämförbara länder och det saknas forskning som tittar på exakt hur dessa ekonomiska värden ska fångas. För att undersöka varför så är fallet och vilken roll öppna data har på värdeskapande i kommunsektorn har denna studie genom kvalitativa intervjuer med en induktiv ansats identifierat flertalet teman. Studien resulterade i en djupare teoretisk analys av öppna data och dess egenskaper. Genom att betrakta det som en kollektiv vara går det att använda flera förklaringsmodeller för att förklara dess långsamma spridning och förstå de svåra förutsättningarna för värdefångst vilket resulterar i incitamentsproblem. Till det finns det strukturella problem kopplat till lagstiftning och infrastruktur som hämmarspridningen av öppna data och dess värdeskapande roll i kommunsektorn.

Resumo: As raças de ovinos localmente adaptadas descendem de animais trazidos durante o período colonial, e durante anos foram submetidas a cruzamentos indiscriminados com raças exóticas. Estas raças de ovinos são consideradas importantes por possuírem características adaptativas às diversas condições ambientais brasileiras. Para evitar a perda deste importante material genético, a Empresa Brasileira de Pesquisa Agropecuária (Embrapa) decidiu incluí-las no seu Programa de Pesquisa em Recursos Genéticos, armazenando-as em seus bancos de germoplasma, sendo que as que possuem maior destaque nacional são as raças Crioula, Morada Nova e Santa Inês. A seleção dos ovinos para compor estes bancos é realizada por meio da avaliação de características morfológicas e produtivas. Entretanto, essa avaliação está sujeita a falhas, pois alguns animais cruzados mantêm características semelhantes àquelas dos animais locais. Desta forma, identificar se os animais depositados nos bancos são ou não pertencentes a uma raça é uma tarefa que exige muita cautela. Em busca de soluções, nos últimos anos houve um aumento significativo no uso de tecnologias que utilizam marcadores moleculares SNP (do inglês Single Nucleotide Polimorphism). No entanto, o grande número de marcadores gerados, que pode chegar a centenas de milhares por animal, torna-se um problema crucial. Para abordar esse problema, o objetivo deste trabalho é desenvolver modelos baseados em técnicas de mineração de dados para selecionar os principais marcadores SNP para as raças Crioula, Morada Nova e Santa Inês. Os dados utilizados neste estudo foram obtidos do Consórcio Internacional de Ovinos e são compostos por 72 animais destas três raças e 49.034 marcadores SNP para cada ovino. O resultado obtido com a conclusão deste trabalho foi um conjunto de modelos preditivos baseados em técnicas de mineração de dados que selecionaram os principais marcadores SNP para identificação das raças estudadas. A partir da intersecção desses modelos identificou-se um subconjunto de 15 marcadores com maior potencial de identificação das raças. Os modelos poderão ser utilizados para certificação das raças de ovinos já depositados nos bancos de germoplasma e de novos animais a serem inclusos, além de subsidiar associações de criadores interessadas em certificar seus animais, bem como o MAPA (Ministério da Agricultura, Pecuária e Abastecimento) no controle de animais registrados. Os modelos gerados poderão ser estendidos para outras espécies animais de produção
Abstract: The locally adapted breeds of sheep are descended from animals brought in during the colonial period, and for years were subjected to indiscriminate crossbreeding with exotic breeds. These breeds of sheep are considered important by having adaptive characteristics to several Brazilian environmental conditions. To avoid the loss of this important genetic material, the Brazilian Agricultural Research Corporation (Embrapa) decided to include them in its Programme of Research in Genetic Resources, storing them in their genebanks, while those with greater national prominence are Creole breeds, Morada Nova and Santa Ines. The selection of sheep to compose these banks is performed through the evaluation of morphological and productive characteristics. However, this assessment is subject to failures, because some crossbred maintains similar characteristics to those of the local animals. Thus, identifying if the animals deposited in banks belong or not to a breed is a challenging task. In search for solutions in recent years there has been a significant increase in the use of technologies that use molecular markers SNP (Single Nucleotide Polimorphism). However, the large number of markers generated, which can reach hundreds of thousands per animal, becomes a crucial issue. To address this problem, the aim of this study is to develop models based on data mining techniques to select the main SNP markers for Creole, Morada Nova and Santa Ines breeds. The data used in this study were obtained from the International Consortium of Sheep and consist of 72 animals e of these three breeds and 49,034 SNP markers for each sheep. The result obtained with this study was a set of predictive models based on data mining techniques to selected major SNP markers to identify the breeds studied. The intersection of the generated models identified a subset of 15 markers, with greater potential for identification of sheep breeds. The models may be used for certification of sheep breeds already deposited in genebanks and new animals to be included, apart from subsidizing breeders associations interested in certifying their animals, as well as MAPA (Ministry of Agriculture, Livestock and Food Supply) in control registered animals. The proposed models can be extended to other species of production animals

Testo completoModern data acquisition systems can be very time consuming to configure. The most time consuming aspect of configuring a data acquisition system is defining the measurements that the system will collect. Each measurement has to be uniquely identified in the system and the system needs to know what data the measurement will sample. Data acquisition systems are capable of sampling thousands of measurements in a single test flight. If all of the measurements are created by hand, it can take many hours to input all of the required measurements into the data acquisition system's setup software. This process can also be extremely tedious since many measurements are very similar. This paper will examine several possible solutions to the problem of rapidly creating large numbers of data acquisition measurements. If the list of measurements that need to be created already exists in an electronic format then the simplest approach would be to create an importer. The two main ways to import data are XML and comma separated value files. This paper will discuss the advantages and disadvantages of both approaches. In addition to importers, this paper will discuss a system that can be used to create large numbers of similar measurements very quickly. This system is ideally suited to MILSTD- 1553 and ARINC-429 bus data. It exploits the fact that most bus measurements are typically very similar to each other. For example, 1553 measurements typically differ only in terms of the command word and the selected data words. This system allows the user to specify ranges of data words for each command word. It can then create the measurements based on the user specified ranges.

Testo completoData integrity in computer based information systems is a concern because of the damage that can be done by unauthorized manipulation or modification of data. While a standard exists for data security, there currently is not an acceptable standard for integrity. There is a need for incorporation of a data integrity policy into the standard concerning data security in order to produce a complete protection policy. There are several existing models which address data integrity. The Biba, Goguen and Meseguer, and Clark/Wilson data integrity models each offer a definition of data integrity and introduce their own mechanisms for preserving integrity. Acceptance of one of these models as a standard for data integrity will create a complete protection policy which addresses both security and integrity.

Resumo: Desde sua origem, as bases de dados Nosql têm alcançado um uso generalizado. Devido à falta de padrões de desenvolvimento nesta nova tecnologia emergem grandes desafios. Existem modelos de dados , linguagens de acesso e frameworks heterogêneos, o que torna a migração de dados ainda mais complexa. A maior parte das soluções disponíveis hoje se concentra em fornecer uma representação abstrata e genérica para todos os modelos de dados. Essas soluções se concentram em adaptadores para acessar homogeneamente os dados, mas não para implementar especificamente transformações entre eles. Essas abordagens muitas vezes precisam de um framework para acessar os dados, o que pode impedir de usá-los em alguns cenários. Entre estes desafios, a migração de dados entre as várias soluções revelou-se particularmente difícil. Esta dissertação propõe a criação de um metamodelo e uma série de regras capazes de auxiliar na tarefa de migração de dados. Os dados podem ser convertidos para vários formatos desejados através de um estado intermediário. Para validar a solução foram realizados vários testes com diversos sistemas e utilizando dados reais disponíveis. Palavras Chave: NoSql Databases. Metamodelo. Migração de Dados.
Abstract: Since its origin the NoSql Database have achieved widespread use. Due to the lack of standards for development in this new technology great challenges emerges. Among these challenges, the data migration between the various solutions has proved particularly difficult. There are heterogeneous datamodels, access languages and frameworks available, which makes data migration even more complex. Most part of the solutions available today focus on providing an abstract and generic representation for all data models. These solutions focus in design adapters to homogeneously access the data, but not to specifically implement transformations between them. These approaches often need a framework to access the data, which may prevent from using them in some scenarios. This dissertation proposes the creation of a metamodel and a series of rules capable of assisting in the data migration task. The data can be converted to various desired formats through an intermediate state. To validate the solution several tests were performed with different systems and using real data available. Key-words: NoSql Databases. Metamodel. Data Migration.

This thesis describes a new software tool to facilitate Parametric Urban Resource Modeling, a method for quantitatively studying and improving the distribution of resources in a city. The software is intended to help users with no CAD or programming experience make digital Parametric Urban Resource Models of cities and optimize them algorithmically using a pre-determined set of rules. These models may help urban planners understand how to raise the population density of an area while maintaining or improving its livability, a critical challenge in our rapidly-urbanizing world. Preliminary feedback regarding this limited early prototype of the software has been promising. Parametric Urban Resource Modeling software such as this may eventually become an important early step in the urban design process, potentially saving time and improving the quality of the final city designs.

Many practical problems in pattern recognition require making inferences using multiple modalities, e.g. sensor data from video, audio, physiological changes etc. Often in real-world scenarios there can be incompleteness in the training data. There can be missing channels due to sensor failures in multi-sensory data and many data points in the training set might be unlabeled. Further, instead of having exact labels we might have easy to obtain coarse labels that correlate with the task. Also, there can be labeling errors, for example human annotation can lead to incorrect labels in the training data. The discriminative paradigm of classification aims to model the classification boundary directly by conditioning on the data points; however, discriminative models cannot easily handle incompleteness since the distribution of the observations is never explicitly modeled. We present a unified Bayesian framework that extends the discriminative paradigm to handle four different kinds of incompleteness. First, a solution based on a mixture of Gaussian processes is proposed for achieving sensor fusion under the problematic conditions of missing channels. Second, the framework addresses incompleteness resulting from partially labeled data using input dependent regularization.
(cont.) Third, we introduce the located hidden random field (LHRF) that learns finer level labels when only some easy to obtain coarse information is available. Finally the proposed framework can handle incorrect labels, the fourth case of incompleteness. One of the advantages of the framework is that we can use different models for different kinds of label errors, providing a way to encode prior knowledge about the process. The proposed extensions are built on top of Gaussian process classification and result in a modular framework where each component is capable of handling different kinds of incompleteness. These modules can be combined in many different ways, resulting in many different algorithms within one unified framework. We demonstrate the effectiveness of the framework on a variety of problems such as multi-sensor affect recognition, image classification and object detection and segmentation.
