Sort and beer: Everything you wanted to know about the sorting task but did not dare to ask
2011
author cannot archive publisher's version/PDF; International audience; In industries, the sensory characteristics of products are key points to control. The method commonly used to characterize and describe products is the conventional profile. This very efficient method requires a lot of time to train assessors and to teach them how to quantify the sensory characteristics of interest. Over the last few years, other faster and less restricting methods have been developed, such as free choice profile, flash profile, projective mapping or sorting tasks. Among these methods, the sorting task has recently become quite popular in sensory evaluation because of its simplicity: it only requires ass…
Does "whole-word shape" play a role in visual word recognition?
2002
To analyze the impact of outline shape on visual word recognition, the visual pattern of the stimuli can be distorted by size alternation. Contrary to the predictions of models that rely on outline shape (Allen, Wallace, & Weber, 1995), the effect of size alternationwas greater for low-frequency words than for high-frequency words in a lexical decision task (Experiment 1). In Experiment 2, the effect of case type (lowercase vs. UPPERCASE) occurred for low-frequency words, but not for high-frequency words. The effect of neighborhood size was remarkably similar in the two experiments. The results can be readily explained in the framework of a resonance model (Grossberg & Stone, 1986), in whic…
Investigating face-to-face and virtual teamwork over time: When does early task conflict trigger relationship conflict?
2012
North Carolina State UniversityPast research has indicated that early task consict can trigger subsequent relationshipconsict during teamwork. The current study examines conditions that may exacerbateor attenuate this relationship. SpeciÞcally, this study examines the moderating role ofprocess consict and communication medium on the link between task consict andrelationship consict over time. A longitudinal laboratory experiment was carried outcomparing 22 face-to-face (FTF) groups, 22 videoconference (VC) groups, and 22synchronous computer mediated (i.e., OchatO) communication (CMC) groups workingon a complex team task over a period of 1 month. Results highlight the robust insuenceof early…
Assessing the Comprehension of Questions in Task-Oriented-Reading // Evaluación de la comprensión de las preguntas en lectura-orientada-a-tareas
2012
El objetivo del estudio fue analizar una metodologia de evaluacion del modelo mental de tarea, en lectura-orientada-a-tareas. 66 estudiantes universitarios leyeron dos textos y contestaron preguntas. Para cada pregunta elaboramos un item sobre las demandas de la pregunta. Las alternativas de respuesta combinaban versiones correctas o erroneas de los componentes del modelo de pregunta; nucleo y proceso. Analizamos el formato de aplicacion, relacion con rendimiento, capacidad para discriminar entre niveles de comprension y funcionamiento psicometrico de los items. Cuando la evaluacion se aplico antes de responder, las puntuaciones mejoraron y se relacionaron con rendimiento. Esta aplicacion p…
Understanding Romanian Texts by Using Gamification Methods
2019
Abstract In recent years, there has been increasing interest in the field of natural language processing. Determining which syntactic function is right for a specific word is an important task in this field, being useful for a variety of applications like understanding texts, automatic translation and question-answering applications and even in e-learning systems. In the Romanian language, this is an even harder task because of the complexity of the grammar. The present paper falls within the field of “Natural Language Processing”, but it also blends with other concepts such as “Gamification”, “Social Choice Theory” and “Wisdom of the Crowd”. There are two main purposes for developing the a…
As We Think We May Teach: Ideologies on IT in the Classroom
2015
The extended use of IT devices has raised scholars’ awareness to its impact on the organization of classroom interactions. Studies claim that the intensive use of IT in the classroom has the potential of revolutionizing education in a way that it increases students’ ownership and control over their learning processes (Ryberg 2013). Others claim that devices such as interactive whiteboards contribute to the emergence of an “effective style” of teaching (Gillen et al. 2007: 254). Further, Lotherington & Ronda (2014) emphasize the role of IT, multimedia, multimodality, collaborative communication, agentive participation and multitasking for a contemporary understanding of what they call “commu…
Selecting information to answer questions: Strategic individual differences when searching texts
2011
The purpose of the study was to explore students’ selection of information strategies in a task-oriented reading situation. 72 secondary school students read two texts and answered six questions per text, three of which were manipulated to induce a misleading matching between the wording of the question and distracting pieces of information in the text. The reading and question-answering were presented with the software Read&Answer. We analyzed how skilled and less-skilled comprehenders were attracted to the distracting pieces of information and how this affected reading patterns and task outcomes. Skilled comprehenders scored higher and were able to discard the distracting information. In …

Assessment of mental stress through the analysis of physiological signals acquired from wearable devices
2019
Mental stress is a physiological state that directly correlates to the quality of life of individuals. Generally speaking, but especially true for disabled or elderly subjects, the assessment of such condition represents a very strong indicator correlated to the difficulties, and, in some case, to the frustration that derives from the execution of a task that results troublesome to be accomplished. This article describes a novel procedure for the assessment of the mental stress level through the use of low invasive wireless wearable devices. The information contained in electrocardiogram, respiratory signal, blood volume pulse, and electroencephalogram was extracted to set up an estimator f…
A Framework for Parallel Assessment of Reputation Management Systems
2016
Several distributed applications running over the Internet use Reputation Management Systems (RMSs) to guarantee reliable interactions among unknown agents. Because of the heterogeneity of the existing RMSs, their assessment in terms of correctness and resistance to security attacks is not a trivial task. This work addresses this issue by presenting a novel parallel simulator aimed to support researchers in evaluating the performances of a RMS since the design phase. Preliminary results obtained by simulating two different attacks confirm the suitability of the proposed framework to evaluate different RMSs.
