Is carousel interaction really usable?

In this paper a novel and significant study into the usability of carousel interaction in the context of desktop interaction is presented. Two equivalent prototypes in an e-commerce context were developed. One version had a carousel and the other version did not have a carousel. These were then compared with each other in an empirical experiment with 40 participants. The data collected were statistically analysed and overall results showed that in terms of performance the Web site version without carousel outperformed the version with carousel. Furthermore, the subjective preferences of the participants were strongly in favour of the without carousel version of the site. The results of this study make an important contribution to knowledge suggesting that in many cases implementing a carousel is not the best design decision. The results of this paper are particularly significant in relation to desktop versioned Web sites and goal-driven tasks. Serendipitous-type tasks and mobile versioned web sites used on mobile devices with touch screens were not part of the scope of this work.

Propuesta de repositorio de información para la difusión de los documentos académicos y científicos que se generan en el Instituto Tecnológico de Tepic

This paper describe a proposal to develop a web site to work as technical, academic and scientific information repository, which contain the daily products made by students and teachers from Tecnológico Nacional de México campus Instituto Tecnológico de Tepic. This proposal comes to cover the opportunity that occurs with the generation of knowledge that is developed in the academic and research work of the institution, by students, teachers and researchers of the different careers and postgraduate courses offered by IT Tepic, and that currently does not have a space where this information is presented and made available to anyone who can use it to base their own scientific development process. The development of this proposal will be worked in conjunction with an Academic Body of the Instituto Tecnológico de Nogales, and once it is implemented, it will subsequently be offered to the other technological institutes of the Tecnológico Nacional de México.

Visualization of Web Spaces: State of the Art and Future Directions

The World Wide Web is a dominant global communication medium and knowledge repository. It is used by a great number of people with a variety of computer skills hence its usability is critical. As with many large information collections, the challenge with web usability is understanding the structure of a collection of information objects (web pages) to find relevant ones for satisfying a specific information need. Web sites are organized in a hyperlinked structure that somewhat addresses this challenge. However, this “connectedness” also causes the now well-known “lost in cyberspace” phenomenon where one may get confused within the complex organization of a web site. Meanwhile, information exploration on the web is not limited to browsing a web site. The problem of finding relevant information applies to a collection of pages that come from various web sites as in the case of the results of a “less than perfectly constructed” search query.<div><br>Information visualization has been proposed as a way to cope with these problems by taking advantage of people’s innate perceptual skills to support their cognitive skills. Many paradigms have been proposed for the visual presentation of web spaces (i.e. structured or unstructured collection of web pages). This study surveys these paradigms to provide a map of where the research in this field is, and what directions future research and practice can take. For this, we introduce a classification scheme to help in the systematic understanding of web visualization and for providing a framework for the development of<br>future visualizations.</div>

The DiGreC Treebank

The DiGreC (DIachrony of GREek Case) treebank is a corpus of selected sentences from Greek texts, ranging from Homer to Modern Greek, which have been annotated morphosyntactically and semantically. The corpus comprises excerpts from 655 texts, for a total of 3385 sentences and 56,440 word tokens; automated tagging and lemmatisation has been supplemented with manual review to ensure accuracy. The data exist in xml and csv formats, which can be manipulated and converted automatically to other schemata. A web site has also been created to allow users to interact with the data more easily, and to provide specialised functionality for searching and visualisation. This corpus was created to inform theoretical debates regarding the role of case in grammar, and may be of use to researchers searching for specific attestations of a range of different constructions in Greek.

Desenvolvimento de um ambiente virtual de aprendizagem sobre linguagem infantil para pediatras

Objetivo: desenvolver e analisar um ambiente virtual de aprendizagem (AVA) sobre a aquisição e desenvolvimento da linguagem infantil voltado à orientação de médicos pediatras. Métodos: o conteúdo abordado foi delimitado considerando as dúvidas que os médicos pediatras possuíam sobre a aquisição e o desenvolvimento da linguagem infantil, e construído a partir de revisão da literatura científica. A produção do material seguiu as fases de desenvolvimento de design instrucional englobando análise e planejamento, modelagem, implementação e avaliação. Foram convidados fonoaudiólogos para participar da avaliação da qualidade do conteúdo e dos recursos tecnológicos utilizando o questionário Health-Related Web Site Evaluation Form Emory e o Questionário de Conteúdo desenvolvido pela pesquisadora. Resultados: o conteúdo contemplou as etapas de desenvolvimento da linguagem, principais características e os marcos do desenvolvimento em cada fase. O material confeccionado está disponível no endereço eletrônico http://fonoaudiologiaparapediatras.wordpress.com. Na etapa de avaliação do AVA, participaram 63 fonoaudiólogos que classificaram o blog como excelente para a qualidade e conteúdo. Conclusão: portanto, um AVA, em formato de blog, contendo informações sobre a aquisição e desenvolvimento da linguagem foi desenvolvido a fim de orientar médicos/pediatras desde fases típicas até alterações, prevenção, fases do desenvolvimento e possíveis encaminhamentos.

Forming of the products of non-hydrostatic modelling systems for short-range weather prediction COSMO-RuBy (Hydrometcentre of Russia) и WRF-ARW (Belhydromet)

The paper considers the results of activities on the development of output products for the non-hydrostatic short-range numerical weather prediction systems: COSMO-RuBy with a grid spacing of 2.2 km at the Hydrometcentre of Russia and WRF-ARW with a grid spacing of 3 km in Belhydromet. The important results of the activities are the organization of the exchange of unified products between the countries and the development at the Hydrometcentre of Russia of two technologies for obtaining the unified products: the multi-model lagged ensemble system and the system for the complex correction based on machine learning of model results. A specialized web-site providing convenient work of forecasters with the COSMO-RuBy results and unified products was created at the Hydrometcentre of Russia based on the feedback from forecasters. The systems of common visualization and verification of COSMO-RuBy and WRF-ARW results are implemented in Belhydromet. Keywords: numerical weather prediction, ensemble forecasting, visualization, machine learning

In Praxis: Creating a (Web)Site of Resistance and Disrupting the Hidden Curricula of Academic Socialization

The navigation and socialization within academia is rife with toxicity and a hidden curricula reflective of neoliberal competitiveness, drawn from White cis-hetero colonialist patriarchy. To challenge and resist the toxicity within academia, Communities of Color have created counterspaces to share resources, build beyond the purported individualism, and connect through vulnerability and care. Within this reflection, are the lessons learned of creating one such counterspace through the development of a website— a “site” of resistance.
