Usability of Programming Languages
2016
Programming languages form the interface between programmers (the users) and the computation that they desire the computer to execute. Although studies exist for some aspects of programming language design (such as conditionals), other aspects have received little or no human factors evaluations. Designers thus have little they can rely on if they want to make new languages highly usable, and users cannot easily chose a language based on usability criteria. This SIG will bring together researchers and practitioners interested in increasing the depth and breadth of studies on the usability of programming languages, and ultimately in improving the usability of future languages. nonPeerReviewed
Usability challenges in digital learning solutions
2015
Usability is a key element in successful software. Ensuring the technical usability of a learning solution enables users to focus on their main task, learning. The purpose of this paper is to demonstrate the results of heuristic usability evaluations of digital learning solutions. Heuristic evaluations were conducted on 24 digital learning solutions from one country (Finland) and two country groups (Asian countries and Spanish speaking countries) concentrating on the usability of the user interface of each evaluated solution. The main results of this study indicate that a few heuristics cover the majority of all usability problems (UPs) observed in learning solutions, but these heuristics c…
An empirical approach for evaluating the usability of model-driven tools
2013
MDD tools are very useful to draw conceptual models and to automate code generation. Even though this would bring many benefits, wide adoption of MDD tools is not yet a reality. Various research activities are being undertaken to find why and to provide the required solutions. However, insufficient research has been done on a key factor for the acceptance of MDD tools: usability. With the help of end-users, this paper presents a framework to evaluate the usability of MDD tools. The framework will be used as a basis for a family of experiments to get clear insights into the barriers to usability that prevent MDD tools from being widely adopted in industry. To illustrate the applicability of …
Anglicisms in Tourism Language Corpora 2.0
2015
Abstract The world of tourism has evolved in recent times because of the impact of the Internet. Tourism enterprises have expanded their commercial point of view and have found a faster way to reach clients through increased tourism advertising on the Web. Along with this increase in advertising are the opportunities to study the lexicon of tourism. One of the main points in this lexicon is the use of foreign words, especially the use of Anglicisms due to English's status as a universal language in these contexts. In this article, we will study the Anglicisms in Spanish tourism from these points of view: • why these words are used; • in what context they are used; • if we use original forei…
Analyzing E-Commerce Websites: A Quali-Quantitive Approach for the User Perceived Web Quality (UPWQ)
2016
<p>The electronic commerce (e-commerce) is an increasingly important phenomenon and this research deals with perceived quality from the users-customers point of view. The aim of this paper is to shed light on the critical factors determining the User Perceived Web Quality (UPWQ) for e-commerce.</p><p>We use the Pareto Chart as qualitative methodology able to identify the UPWQ considering not only technical features (ease of use, design, smart phone and tablet responsivity, information), but also emotional features such as trust, empathy, free shipping and discount. The Pareto chart main has the advantage to classify the selected features by their relevance.</p><p&…

2014
International audience; English. The SENTIment POLarity Classification Task (SENTIPOLC), a new shared task in the Evalita evaluation campaign , focused on sentiment classification at the message level on Italian tweets. It included three subtasks: subjectivity classification, polarity classification, and irony detection. SENTIPOLC was the most participated Evalita task with a total of 35 submitted runs from 11 different teams. We present the datasets and the evaluation methodology, and discuss results and participating systems. Italiano. Descriviamo modalit a e risultati della campagna di valutazione di sistemi di sentiment analysis (SENTIment POLarity Classification Task), proposta per la …

2001
Betrachtet man die Entwicklung des Internet in den letzten drei bis vier Jahren aus Sicht der Unternehmen, so fallt auf, das der wirtschaftliche Nutzen des elektronischen Handels lange Zeit unterschatzt wurde.452 Viele Unternehmen befinden sich in Warteposition, um im richtigen Moment mit elektronischen Geschaftsaktivitaten zu starten.453 Selbst Medienriese Bertelsmann und Microsoft haben lange Zeit das Potential fur Innovationen unterschatzt, welches sich den Unternehmen durch das Medium Internet offnet.454 Als Grund fur ihre Zuruckhaltung geben viele Unternehmen die Frage nach dem wirtschaftlichen Nutzen an, der ihnen durch eine Web Site entstehen soll.455
Web Site Promotion in der Phase „Web Site Online“
2001
An wen denken die meisten Menschen, wenn sie Bucher im Internet bestellen wollen? Vermutlich an den Weltmarktfuhrer „Amazon.com“. Die Internet-Adresse des ABC-Bucherdienstes, Deutschlands groster Online-Buchversand, sowie Deutschlands zweitgroster Versand, die Bucher.de AG, sind im Vergleich zu Amazon.com weit weniger bekannt. In „Deutschlands umfangreichstem Web-Katalog“, in Web.de, sind fast 600 weitere Firmen gelistet, bei denen man Bucher im Internet bestellen kann. Eine erfolgreiche Marktprasenz ist bei diesen Unternehmen ausschlieslich abhangig von dem Bekanntheitsgrad ihrer Internetadresse. Einige Unternehmen wie z. B. Dell tatigen bereits Jahresumsatze in der Hohe von mehr als einer…
Air Pollution Research Based on Spider Web and Parallel Continuous Particulate Monitoring—A Comparison Study Coupled with Identification of Sources
2021
Air pollution is monitored mainly in urban or industrial areas, even if it is known that in rural ones, low emission can significantly worsen air quality. Hence, cheap and easily accessible methods of monitoring are needed. Recently, spider webs biomonitoring is getting popular, however, there is no information about its comparison with active methods. In this study, PTEs accumulated on spider webs were compared with results from continuous particulate monitor (CPM). Generally, higher potentially toxic elements concentrations were noted in spider web, with exception in the case of Zn. Zn may be present rather in smaller fractions, hence it needs more time for accumulation on spider web whil…
Assessing anthropogenic pressures on coastal marine ecosystems using stable CNS isotopes: State of the art, knowledge gaps, and community-scale persp…
2015
Abstract In recent decades, the analysis of carbon, nitrogen and sulfur stable isotopes (SIA) has emerged as a powerful, viable methodology for examining food web structure and dynamics, as well as addressing a number of applied issues. Here, we provide a state-of-the-art review of the use of SIA for assessing anthropogenic pressures on natural ecosystems, in order to establish current knowledge gaps and identify promising applications for evaluating the ecological status of marine coastal waters. Specifically, the potential of SIA to provide food web-scale indicators for estimating cumulative anthropogenic pressures is addressed. The review indicates that the methodology has been used for …
