Funktionskreis e Gestaltkreis: la metafora del circolo nella biologia teoretica
2014
This paper aims to examine the use of the circle metaphor within the functionalist perspective by Jakob von Uexküll and the morphological perspective by Viktor von Weizsäcker. Whereas the functionalist theory dissolves the unity of the organism in the multiplicity of functional relationships, Weizsäcker’s morphology recognizes the fundamental unity of the biological act, leading to a new concept of the living organism.
Pseudo-relatives, gerunds and infinitives in Romance: (only) superficial resemblances and structural connections
2013
L'argomento di questa monografia è un confronto tra i costrutti predicativi di tipo frasale nelle diverse varietà romanze. Mentre le pseudorelative sono diffuse pressoché in tutta la Romània, con qualche variazione parametrica minore, i gerundi predicativi e gli infiniti preposizionali sono usati solo in alcune varietà. Negli studi linguistici sull'argomento è mancata finora l'ottica comparativa, sia tra varietà diverse, sia tra costrutti predicativi diversi. Il mio lavoro si prefissa lo scopo di colmare questa lacuna, senza ignorare però i costrutti percettivi composti da un infinito semplice, che da parte della letteratura sono stati paragonati alle strutture predicative delle pseudorelat…
Investigating teachers’ dyadic self-efficacy and its correlations to students’ perceptions of teacher efficacy and student well-being
2022
Most studies, to date, have ignored variance in teachers’ self-efficacy (TSE) in relation to teaching individual students (i.e., student-specific self-efficacy). However, TSE and teacher efficacy differ among students. Thus, this study examines dyadic TSE in four domains and their correlations with students’ perceptions of teacher efficacy and student academic self-concept and well-being. Results of a paper–pencil survey involving 29 teachers and 469 students (39.9% girls, aged 10–17 years) from German secondary schools reveal a moderate overlap between dyadic TSE and students’ perceptions of teacher efficacy. Furthermore, they reveal variance in how teachers’ and students’ ratings are rela…
Tapology: A Game-Based Platform to Facilitate E-Health and E-Inclusion
2014
Published version of a chapter in the book: Universal Access in Human-Computer Interaction. Aging and Assistive Environments. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-07446-7_36 We have developed a tablet computer game app for low vision users that can be used to introduce a platform for gaming, internet and visual rehabilitation to older users who have not had prior experience with information communication technology (ICT). Our target user group is people diagnosed with Age Related Macular Degeneration (AMD). The primary goal of the app is to present a fun and engaging means for participants to engage with Information Communication Technology (ICT). A long…
An Empirical Examination of the Economics of Mobile Application Security
2021
The growth of mobile devices coupled with the advances in mobile technologies has resulted in the development and widespread use of a variety of mobile applications (apps). Mobile apps have been developed for social networking, banking, receiving daily news, maintaining fitness, and for job-related tasks. The security of the apps is an important concern. However, in some cases, the app developers may be less interested to invest in the security of the apps, if users are unwilling to pay for the added security. In this paper, we empirically examine whether consumers are less willing to pay for security features than for usability features. In addition, we examine whether a third-party certif…
Customers' Perceived Risk and Trust in Using Mobile Money Services—an Empirical Study of Ghana
2019
Although mobile money (MM) has been explored in the existing literature, the roles of trust and risk in MM use have received little attention from researchers. Furthermore, many of the existing studies have treated these constructs as unidimensional. The extant literature also shows that perceived risk has received little attention from researchers who have conducted studies on MM. Thus, the objective of this study is to examine the roles of trust and perceived risk in customers' intent to adopt MM services in Ghana. Both trust and perceived risk were broken down into various dimensions. The study involved 671 respondents who were selected via an intercept approach and an online survey. Str…
In search of perceptual and acoustical correlates of polyphonic timbre
2009
Polyphonic timbre refers to the overall timbre mixture of a music signal, or in simple words, the 'global sound' of any piece of music. It has been proven to be an important element for computational categorization according to genre, style, mood, and emotions, but its perceptual constituents have been less investigated. The aim of the study is to determine the most salient features of polyphonic timbre perception by investigating the descriptive auditory qualities of music and mapping acoustic features to these descriptors. Descriptors of monophonic timbre taken from previous literature were used as a starting point. Based on three pilot studies, eight scales were chosen for the actual exp…
Entornos virtuales de aprendizaje: modelo ampliado de aceptación de la tecnología
2019
Dentro de la actual renovación de las metodologías docentes, las universidades están impulsando el uso de entornos virtuales de aprendizaje como una herramienta básica en la enseñanza presencial, ya que permite flexibilizar e individualizar la educación. El objetivo del presente trabajo es aportar evidencia empírica sobre la percepción que tienen los alumnos respecto a la mejora en su aprendizaje, al adoptar y utilizar entornos virtuales en la enseñanza presencial, a partir del Modelo de Aceptación de la Tecnología ampliado. La población objeto del estudio son 251 casos de estudiantes de primer grado de la Facultad de Economía de la Universitat de Valencia. Se ha evidenciado empíricamente, …
"Mutta niille ei voi mitään, joilla on aivoissa vika" : mielisairauden kansanomaiset tulkinnat 1900-luvun alkuvuosikymmenten modernisoituvassa Suomes…
2015
Artikkelissa tarkastellaan mielisairauden kansanomaisia tulkintoja 1900-luvun ensimmäisinä vuosikymmeninä, jolloin mielisairaita ja muita marginaaliryhmiä koskeva yhteiskunnallinen keskustelu kävi vilkkaana. Mielisairaat alkoivat degeneraatioteorioiden myötä näyttäytyä modernisoituvan yhteiskunnan ei- toivottuina toisina, joiden henkinen ja fyysinen rappio uskottiin perinnölliseksi. Mielisairaaloiden lukumäärää lisättiin, mutta merkittävä osa mielisairaiksi katsotuista eli yhä laitosten ulkopuolella, esimerkiksi elätteellä maaseudun yksityisissä perheissä. Artikkelissa selvitetään, miten mielisairaisiin suhtaudutaan aikakauden maallikkokerronnassa ja millaisia käsityksiä esitetään mielisair…
Influence of Musical Context on the Perception of Emotional Expression of Music
2013
Factors determining and influencing the perception of emotional expression of music include those related to music itself, to the listener, and to the context. Among the latter there is also music, as we rarely listen to a single piece. A simple experimental study has been carried out into the effect of music listened to immediately beforehand on the perception of the emotional expression of a musical piece. The following variables were involved: type of emotional expression of music conceived in terms of a most basic sad-joyful dimension, initial and final mood of the listeners, their professional musical education vs. lack thereof, age, and gender. The subjects were students of three age …
