Abstract

Mobile devices today have become the center of our connectivity. Radio companies tailor their content in several ways: podcasting, streaming, and mobile applications. The aim of this paper is to learn more about the mobile app content of the most popular talk radio stations in Spain. For this purpose, in January 2015 we conducted a qualitative content analysis in order to establish the type of products provided, their structure and hierarchy, and to determine to what extent Spanish talk radio stations are taking full advantage of this new potential.

Abstract

It is quite common in the library and information world to find mobile applications (apps) to query scientific journals, bibliographic databases or university libraries. However, there are no apps that offer bibliometric indicators about universities, researchers, etc. We describe the development and functionality of the pioneer bibliometric app UGRinvestiga, launched on January 2015, which offers rankings of researchers from the University of Granada based on citations collected from Google Scholar Profiles. Information on the technical features of the app, the data collection process, the indicators used, the current coverage of researchers and a description of its interface and functionalities are described. Finally we emphasize the great potential of mobile applications as a tool for representing and disseminating bibliometric data.

Abstract

The increasing relevance of personal information has sparked a broad debate on privacy issues on the ubiquitous Internet. The so called ‘privacy paradox’ aims to explain through rational decision-making models the contradictions between stated digital privacy concerns and the actual behaviors in mobile platforms. An analysis of the emotions that arise when users know about unauthorized personal data disclosure is proposed. A survey of smartphone users was conducted shortly after the Cambridge Analytica / Facebook scandal took place, in order to analyze the nature and intensity of a user’s emotions in relation to their knowledge of privacy breaches. The results support the paradox of privacy from an emotional perspective: although the reported emotions are intense, there is no relationship between the management that users make of their privacy settings in social networks and mobile applications and the nature and intensity of the emotions reported.

Abstract

The Internet of Things (IoT) is one of the key ingredients for the realization of Smart Cities. IoT devices are essential components of the Smart Cities infrastructure, as they can provide information collected from the environment through sensors or allow other systems to reach out and act on the world through actuators. IoT data collection, however, is not limited to sensors and machines, but to data from social networks, and the web. Social networks have a huge impact on the amount of data being produced daily, becoming an increasingly central and important data source. The exploitation of these data sources, combined with the growing popularity of mobile devices, can lead to the development of better solutions to improve people’s quality of life. This paper discusses how to take advantage of the benefits of mobile devices and the vast range of information sources and services, such as traffic conditions, and narrow, closed or conditioned roads data. The proposed system uses a real-time collection, organization, and transmission of traffic and road conditions data to provide efficient and accurate information to drivers. With the purpose of supporting and improving traffic data collection and distribution, an Android application was developed to collect information about extraordinary events that take place in a city, providing warnings and alternative routes to drivers and helping them to improve their time management. The developed solution also exploits the existing gaps in other applications, implementing a more specific solution for the Madeira Island traffic condition problems. info:eu-repo/semantics/acceptedVersion Document type: Part of book or chapter of book

Abstract

Due to the increase of the greenhouse effect and consequent climate changes, over the years, plans for reducing carbon emissions have been presented and discussed. One of the best ways for reducing and neutralizing carbon emissions is to use of collective transports, which is also one of the most accessible forms of contribution for the general public. However, it is not always simple or appealing. Therefore, one of the main goals of this work was to contribute in reducing the carbon emissions and to increase the sustainability of the urban areas. With that purpose in mind, a system that provides real-time information to the user was implemented, in order to encourage more people to use public transportation — and its impact was measured. The selected information was the following: real-time location of the bus, estimated time of arrival of the bus, route mapping, information about each stop. This information is presented to the user through dynamic signaling at main stops and internet services for computers and mobile phones. The developed work, in order to achieve the objectives mentioned, was to create a complete system of real-time information for public transportation in the Centro Region of Portugal, including a mobile app, a website and the backend for all the service and communications. The impact was measured by conducting surveys, presenting the project to the common population on an early state and, posteriorly, demonstrating and encouraging the use of the functional prototype. Devido ao aumento do efeito de estufa e consequentes alterações climáticas, ao longo dos anos, têm-se vindo a apresentar e a debater planos para a redução das emissões de carbono. Um dos caminhos indicados para a redução e neutralização do carbono é o uso de transportes coletivos, sendo também uma das formas de contribuição mais acessível ao público geral. Porém, nem sempre é algo simples ou apelativo. Assim, um dos grandes objetivos deste trabalho foi contribuir para reduzir as emissões de carbono e aumentar a sustentabilidade nas áreas urbanas. Com este propósito em mente, foi implementado um sistema que fornece informação ao utilizador em tempo real, de forma a encorajar mais pessoas a utilizarem os transportes públicos — e o impacto final foi medido. A informação selecionada foi a seguinte: localização em tempo real do autocarro, tempo estimado de chegada do autocarro, mapa da rota, informação sobre cada paragem. Esta informação é apresentada ao utilizador através de sinalização dinâmica nas paragens principais e de serviços de internet para computador e telemóvel. O trabalho desenvolvido, de forma a atingir os objetivos mencionados, consistiu em criar um sistema em tempo real completo para transportes públicos na Região Centro de Portugal, incluindo uma aplicação móvel, um website e um servidor backend para estabelecer os serviços e comunicações. O impacto foi medido através de inquéritos, apresentando o projeto à população numa fase inicial e, posteriormente, demonstrando e incentivando o uso do protótipo funcional.

Abstract

Rapid adoption of smartphones and the business success of the Apple App Store have resulted in the rampant growth of mobile applications. Seeking new revenue opportunities from application development has created a gold rush. However, free or very cheap applications constitute a great bulk of the application downloads putting great pricing pressure on the developers. Furthermore, usage statistics suggest that most of the applications have been either one-trick applications or are downright useless, meriting no attention from the user beyond the first day. This is not surprising since cheap prices will dissuade developers from investing large sums of money to continue to develop more sophisticated, high quality applications. Developers have been complaining about the lack of visibility of their applications in stores that are beginning to resemble a high volume warehouse. It is clear that enhancing application discovery and building better marketing tools will be essential for the continued success of the mobile application marketplace and application stores. This paper proposes and investigates techniques for effective discovery of applications by matching user interests with application characteristics, with a special focus on adapting classical data mining techniques to user ratings of the applications. The user ratings are leveraged to make recommendations on potential applications of interest. Publisher's Version
