Texto completoTraditional models of usability are not sufficient for software in the home, since they are built with office software in mind. Previous research suggest that social issues among other things, separate software in homes from software in offices. In order to explore that further, the use qualities to design for, in software for use in face-to-face meetings at home were contrasted to such systems at offices. They were studied using a pluralistic model of use quality with roots in socio-cultural theory, cognitive systems engineering, and architecture. The research approach was interpretative design cases. Observations, situated interviews, and workshops were conducted at a Swedish bank, and three interactive television appliances were designed and studied in simulated home environments. It is concluded that the use qualities to design for in infotainment services on interactive television are laidback interaction, togetherness among users, and entertainment. This is quite different from bank office software that usually is characterised by not only traditional usability criteria such as learnability, flexibility, effectiveness, efficiency, and satisfaction, but also professional face management and ante-use. Ante-use is the events and activities that precedes the actual use that will set the ground for whether the software will have quality in use or not. Furthermore, practices for how to work with use quality values, use quality objectives, and use quality criteria in the interaction design process are suggested. Finally, future research in design of software for several co-present users is proposed.

Estimar a prevalência de uso de substâncias psicoativas, inclusive álcool e tabaco entre estudantes do ensino fundamental e médio de escolas públicas e privadas de uma cidade do interior paulista, assim como, identificar e analisar fatores preditores e protetores do uso de drogas. Metodologia: Foi realizado estudo transversal, com a aplicação de questionário estruturado, previamente testado, individual, anônimo, de auto-preenchimento e participação facultativa para alunos de escolas públicas e privadas, do ensino fundamental e médio do município. Resultados: Participaram do estudo 1933 indivíduos, sendo 50,2% do sexo masculino. A idade média foi de 15,1 l 1,5 anos. O álcool foi a droga mais consumida na vida e nos últimos trinta dias (respectivamente, 69,9% e 41,1%), seguido do tabaco (23,5% e 10,2%), maconha (7,3% e 3,8%) e solventes (7,2% e 2,9%). São apresentados valores de odds ratio para os principais fatores de risco e proteção ao uso de drogas identificados no trabalho, assim como os já ressaltados pela literatura (sexo, idade, classe econômica, religião, escolaridade - fundamental e médio, mesada, trabalho remunerado e tempo livre). Discussão: Discute-se a adequação de programas de prevenção desenvolvidos na escola, no período em que os escolares se encontram ainda em momento de experimentação e fases iniciais do uso de drogas, abordando aspectos relacionados à promoção da saúde, melhoria das condições de vida, atitudes pessoais e organização social, assim como, características e necessidades regionais.
To estimate the prevalence of the use of psychoactive substances, including alcohol and tobacco, among elementary and middle-school students in public and private schools from one city in the interior of Sao Paulo state, as well as to identify and analyze factors that predict and protect from the use/abuse of drugs. Methodology: A transversal study was accomplished with application of a structured questionnaire - previously tested, individual, anonymous, self-completed, and of facultative participation - for students of public and private schools of elementary and high school education. Results: A total of 1933 individuals participated in the study, 50.2% male. The mean age was 15.1 l 1.5 years. Alcohol was the drug most consumed throughout life and in the prior thirty days (respectively, 69.9% and 41.1%), followed by tobacco (23.5% and 10.2%), marijuana (7.3% and 3.8%) and solvents (7.2% and 2.9%). Odds ratio values are presented as the principal protective and risk factors for drug use identified in the work, as well as those already highlighted in the literature (sex, age, economic class, religion, education level - elementary and high school, monthly allowance, remunerated work and free time). Discussion: The adequacy of prevention programs developed in the school is discussed, for the period in which students are found still at the moment of experimentation and initial phases of drug use, dealing with aspects related to health promotion, improvement of life conditions, personal attitudes and social organization, as well as regional characteristics and necessities.

Syftet var också att undersöka hur deltagande design påverkar design processen och dess resultat.För att skapa ett system med en hög grad användarbarhet har ett antal regler och riktlinjer som berör användarbarhet och ett antal begrepp inom interaktionsdesign använts av utvecklingslaget som verktyg.Även om studien visar att användning av användarbarhetsriktlinjer kan vara ett värdefullt verktyg och erbjuda en god grund är det viktigt att använda fler tekniker. Till exempel användandet av deltagande design, som i studien har funnits vara av stort värde för utvecklingslaget.

Texto completoRobotindustrin växer fort tillsammans med efterfrågan på robotar, men de är idag fortfarande relativt komplicerade att programmera för någon utan tidigare erfarenhet av robotar och/eller programmering. Vi har utvecklat ett webbaserat grafiskt användargränssnitt och skriptspråk för programmering av robotarmar. Målet var att göra användargränssnittet så pass lättanvänt att personer utan tidigare erfarenhet kan använda det för att programmera robotar. Vår slutprodukt är en webbaserad drag-and-drop-applikation som generar robotkod i FeatherScript, ett skriptspråk byggt av oss under detta projekt. Det grafiska användargränssnittet uppfyller alla tekniska krav och genom att utföra en enkät om användarbarhet så kan vi även konstatera att gränssnittet är enkelt att använda.

Texto completoThis study set out to investigate the provision and use of public library services in Nigeria with a view to determining the satisfaction level of users with the services offered. Additionally the study wanted to develop a framework that will address the issues and challenges identified when providing public library services to the Nigerian population. Providing access to information through an institution such as a public library presupposes a well-governed and efficiently managed system. Lacking these, service delivery might be compromised, resulting in a population dissatisfied with the services delivered. The study is centred on the IFLA Public Library Service Guidelines, with the use of theoretical models such as the Traditional Public Administration Model (TPAM) and the New Public Management (NPM). An interpretivist approach to research was adopted involving mainly qualitative methods. A quantitative paradigm was also used as a supplementary method. The case study design methodology was used by conducting in-depth interviews with three permanent secretaries, six public library directors, and six heads of rural community libraries, cutting across the six geo-political zones in Nigeria. An informal interview was held with the children using the public library services in order to gauge their opinion about the services provided in the children’s section of the library. A questionnaire was administered to public library users in order to understand their responses on awareness, accessibility, use and satisfaction with the services provided by public libraries. Observation was used for validation of the responses from the interviews and questionnaire. In all, fifteen interviews were conducted with the administrators/managers of public libraries in Nigeria. The reason for using multiple instruments (interview, observation and questionnaire) was for triangulation of the responses in order to identify areas of divergence and convergence during data analysis. The interview responses were thematically analysed using content analysis, while the data collected through a survey questionnaire were analysed using the statistical packages for social sciences (SPSS) in order to arrive at summary and descriptive statistics. A test-retest reliability method using two methods was imperative; (1) expert opinion where a content validity index (CVI) was computed, and (2) Cronbach’s Alpha, that became more useful where continuous and non-dichotomous data were included in the analysis. It was therefore concluded that the instrument was internally consistent and reliable. Ethical considerations were also taken into account with informed consent forms, approval seeking, permission as well as confidentiality. vi The findings of this study showed that variables such as: relevant academic qualifications, years of experience, and designation of the administrators of public libraries affected the service delivery. The study also revealed that the pattern of administration of public libraries in Nigeria still conforms to the Traditional Public Administration Model (TPAM), which was criticised for its top-down and inefficient administrative approach. Very little community participation in the administration of the public libraries was identified, and it was established that there is still a huge dependency on the parent bodies for decision-making and funding. Additionally the study also found the following challenges as impediments to the expected service delivery: inadequate funding; insufficient staff; irregular electricity supply; outdated library materials; lack of functional library resources and facilities; and inappropriate public library legislation. Digital resources were found to be lacking in most of the libraries, and the physical infrastructure was found lacking, especially in the rural areas. Awareness of the services provided by the public libraries was found to be low, and it is mainly traditional services that are currently offered. This situation subsequently resulted in a low level of satisfaction with the use of the services. The study recommended that laws specific to public libraries should be promulgated in order to regulate the governance and administration of this public unit; more relevant and adequate services should be provided; alternative forms of funding should be explored in order to alleviate the dependence on governmental budgets; and training and retraining of public library staff should be actively explored with special emphasis on attaining IT skills.

Texto completoThis master thesis investigates the principal capability of artificial evolution to produce tool use behavior in adaptive agents, excluding the application of life-time learning or adaptation mechanisms. Tool use is one aspect of complex behavior that is expected from autonomous agents acting in real-world environments. In order to achieve tool use behavior an agent needs to identify environmental objects as potential tools before it can use the tools in a problem-solving task. Up to now research in robotics has focused on life-time learning mechanisms in order to achieve this. However, these techniques impose great demands on resources, e.g. in terms of memory or computational power. All of them have shown limited results with respect to a general adaptivity. One might argue that even nature does not present any kind of omni-adaptive agent. While humans seem to be a good example of natural agents that master an impressive variety of life conditions and environments (at least from a human perspective, other examples are spectacular survivability observations of octopuses, scorpions or various viruses) even the most advanced engineering approaches can hardly compete with the simplest life-forms in terms of adaptation. This thesis tries to contribute to engineering approaches by promoting the application of artificial evolution as a complementing element with the presentation of successful pioneering experiments. The results of these experiments show that artificial evolution is indeed capable to render tool use behavior at different levels of complexity and shows that the application of artificial evolution might be a good complement to life-time approaches in order to create agents that are able to implicitly extract concepts and display tool use behavior. The author believes that off-loading at least parts of the concept retrieval process to artificial evolution will reduce resource efforts at life-time when creating autonomous agents with complex behavior such as tool use. This might be a first step towards the vision of a higher level of autonomy and adaptability. Moreover, it shows the demand for an experimental verification of commonly accepted limits between qualities of learned and evolved tool use capabilities.

Una decisión que apoyó esta postura de que sí estaban protegidas hizo que un Juzgado de Distrito conociera sobre el fair use (uso justo en español), o no de las interfaces. Este caso falló a favor de Google declarando que la implementación del código declarativo y sus secuencias, estructura y organización de las 37 APIs de Java, propiedad de Oracle efectivamente fue un uso justo, siendo clave dentro de la interoperabilidad de los programas informáticos y de la innovación.

Forest harvest for bioenergy is growing rapidly, spurred by the European Commission's declaration that bioenergy is carbon-neutral. Bioenergy advocates argue that the carbon released upon the combustion of harvested wood should eventually be reabsorbed from the atmosphere when the harvested land regrows. Recent studies, however, find that wood bioenergy can exacerbate climate change because it is less efficient than the fossil fuels it displaces, and because regrowth takes time and is uncertain. Other land use, land-use change, and forestry (LULUCF) practices can also cause significant carbon fluxes to and from the atmosphere that vary over time as the carbon sequestered in the biomass and soils on each land type changes. Understanding these complex interactions requires an explicit dynamic model that accounts for various land uses and regions, each with carbon content and flux characteristics specific to their respective vegetation, soil distributions, and climatic domains. This work extends the widely used C-ROADS climate model, originally developed with a single biosphere, to incorporate this level of detail. Built up from a diverse set of highly resolved geospatial databases for land cover, soils, climatic domains, and other relevant characteristics, the model aggregates the data into six land use types (natural forest, harvested forest, cropland, pasture, permafrost, and developed/other land) within six major regions (the US, EU, China, India, Other Developed Nations, and Other Developing Nations). It is used to analyze the impact of harvesting forests for bioenergy. Because wood bioenergy is less efficient than the fossil fuels it displaces, the first impact is an increase in atmospheric CO₂ . If the land regrows as forest, this carbon debt can eventually be repaid. However, the time required to do so is long, ranging from 20 to 186 years, depending on the region supplying the wood and whether the forest is thinned or clear-cut. Converting forest to cropland after harvest increases atmospheric CO₂ concentrations without payback. Results also show that afforestation programs are most effective in reducing atmospheric CO₂ when implemented in regions with more tropical climates due to the higher carbon density of these forests. This fast, regionally specific, multi-land-use model enables policy makers and other stakeholders to quickly design and evaluate of a wide range of LULUCF and bioenergy policy scenarios and their climatic effects.

Espera-se que o desenvolvimento de suítes de teste a partir de modelos possa contribuir substancialmente para a redução do esforço humano e aumentar a eficácia dos testes gerados. Entende-se por eficácia (ideal) dos testes o percentual de defeitos existentes encontrados a partir desses testes. Uma grande parte dessas técnicas baseia-se em máquinas de estado e quase sempre estão voltadas para o teste de funcionalidade. Entretanto, existe a necessidade de se poder testar sistemas altamente interativos, tais como smartphones e tablets, a partir de uma descrição de sua interface humano-computador. O objetivo da dissertação é efetuar uma primeira avaliação de uma técnica voltada para a geração de suítes de teste visando o teste de interfaces gráficas. Para tal,desenvolvemos e avaliamos a eficácia de uma ferramenta, chamada Easy, que utiliza casos de uso tabulares e máquina de estados para a geração automática da suíte de testes. Os casos de uso são descritos em linguagem natural restrita. A partir dessa descrição, a ferramenta constrói uma máquina de estado e, a seguir, a utiliza para gerar cenários. Por construção os cenários estarão em conformidade com os casos de uso. Cada cenário corresponde a um caso de teste. Os cenários são apresentados ao usuário em linguagem natural restrita, permitindo a visualização destes antes da geração dos scripts finais de testes. Os scripts gerados são destinados a uma ferramenta de execução automatizada voltada para o teste de interfaces gráficas. Neste trabalho, utilizou-se a ferramenta UI Automation, responsável pela execução de testes em aplicações destinadas ao iOS, sistema operacional de iPhone, iPad e iPod Touch. A eficácia do processo foi avaliada em uma aplicação real, disponível na loja virtual de aplicativos App Store. Além disso, foram realizados testes de IHC afim de avaliar a influência no custo da produção da suíte de teste.
It is expected that the development of test suites from models can contribute substantially to reducing the human effort and to increase the effectiveness of the generated tests. Means for tests’ effectiveness (ideal) the percentage of existing defects found by these tests. Most of these techniques is based on state machines and mostly directed to testing the functionality. However, there is a need to be able to test highly interactive systems, such as smartphones and tablets, from a description of its human computer interface. The goal of the dissertation is to make a first evaluation of a technique aimed to generate test suites for test of human computer graphic interface. For this purpose was developed and evaluated its effectiveness, a tool called Easy, using use cases tabular and state machine for the automatic generation of the suite tests. The use cases are described in natural language restricted. From this description, the tool builds a state machine, and then uses this to generate scenarios. By construction scenarios will be in accordance with the use cases. Each scenario corresponds to a test case. The scenarios are presented to the user in natural language, allowing the visualization of them before the generation of the final scripts tests. The generated scripts are intended to a running automated tool geared to testing graphical interfaces. In this work, we used the UI Automation tool, responsible for running tests on applications for the iOS, operational system for iPhones, iPads and iPod touchs. The effectiveness of the procedure was evaluated in a real application, available in the online store applications App Store. In addition, HCI tests were performed in order to evaluate the influence on the cost of production of the test suite.

The Reservoir Sedimentation Database (ResSed), a catalogue of reservoirs and depositional data that has recently become publicly available, allows for rapid calculation of sedimentation and capacity-loss rates over short (annual to decadal) timescales. This study is a statistical investigation of factors controlling average sediment yield (Y) in eastern United States watersheds. I develop an ArcGIS-based model that delineates watersheds upstream of ResSed dams and calculate drainage areas to determine Y for 191 eastern US watersheds. Geomorphic, geologic, regional, climatic, and land use variables are quantified within study watersheds using GIS. Sediment yield exhibits a large amount of scatter, ranging from 4.7 to 3336 tonnes1km 2year-1. A weak inverse power law relationship between drainage area (A) and Y (R2 = 0.09) is evident, similar to other studies (e.g., Koppes and Montgomery, 2009). Linear regressions reveal no relationship between mean watershed slope (S) and Y, possibly due to the relatively low relief of the region (mean S for all watersheds is 6°). Analysis of variance shows that watersheds in formerly glaciated regions exhibit a statistically significant lower mean Y (159 tonnes1km-2year-1) than watersheds in unglaciated regions (318 tonnes1km-2year-1), while watersheds with different dam purposes show no significant differences in mean Y. Linear regressions reveal no relationships between land use parameters like percent agricultural, and percent impervious surfaces (I) and Y, but classification and regression trees indicate a threshold in highly developed regions (I > 34%) above which the mean Y (965 tonnes1km-2year-1) is four times higher than watersheds in less developed (I < 34%) regions (237 tonnes1km 2year-1). Further, interactions between land use variables emerge in formerly glaciated regions, where increased agricultural land results in higher rates of annual capacity loss in reservoirs (R2 = 0.56). Plots of Y versus timescale of measurement (e.g., Sadler and Jerolmack, 2014) show that nearly the full range of observed Y, including the highest values, are seen over short survey intervals (< 20 years), suggesting that whether or not large sedimentation events (such as floods) occur between two surveys may explain the high degree of variability in measured rates
