Efectos del diseño de la tienda virtual en el comportamiento de compra: tipificación del consumidor online

Cuando una empresa se decide a realizar una iniciativa comercial en Internet, al igual que en el mundo físico, es necesario definir un diseño adecuado del sitio web que se ajuste a su idea de negocio y a su público objetivo. El presente trabajo trata de analizar como influye el diseño del establecimiento virtual en el desarrollo de la gestión comercial, incidiendo en los siguientes aspectos: diseño gráfico, usabilidad y accesibilidad. A partir de este análisis, se estudian los distintos grupos de consumidores con comportamientos homogéneos y se posicionan en función de sus actitudes. El análisis también permite definir la calidad del servicio prestado por este tipo de establecimientos, así como las principales dimensiones en que se despliega. En las conclusiones se citan aspectos en los que el gestor de una tienda online debe incidir para mejorar la calidad de su servicio.

The Impact of ICTs on Lecturer and Student Interaction in University Education Processes

Interaction is a basic element in any educational process, and it is something that needs to be reconsidered in the light of technology. In order to examine the methodological changes that ICTs bring to teaching from an interaction perspective, a study was carried out at the University of Lleida to observe interaction processes in various face-to-face, blended learning and e-learning subjects. The methodological design was based on three data collection techniques: documentary analysis of subject curricula, lecturer and student questionnaires, and lecturer interviews. The data showed that, as the online component of subjects increased, the lecturers and students used more technological tools to communicate (e-mail, forums, chats, social networks, etc.). Furthermore, we found that the lecturers and students basically communicated for academic purposes. While they hardly ever communicated for personal reasons (guidance, support, etc.), they claimed that closer contact with a non-academic focus would be preferable. We also observed that the students’ work was more individual in e-learning subjects. Although there is still a considerable way to go in ICT-mediated lecturer-student interaction, both the lecturers and students recognise the potential of such technologies, even though they still do not use them as they feel they should.

La influencia de las TIC en la interacción docente y discente en los procesos formativos universitarios

La interacción, un elemento básico en cualquier proceso formativo, debe replantearse con la irrupción de la tecnología. Con la intención de abordar los cambios metodológicos que las TIC implican en la docencia desde la perspectiva de la interacción que generan, se planteó un estudio en la Universidad de Lérida para observar los procesos que interactúan en diferentes asignaturas en función de si éstas se desarrollaban bajo la modalidad presencial, semipresencial o no presencial. El diseño metodológico se articuló alrededor de tres técnicas de recogida de datos: análisis documental de programas de asignaturas, cuestionarios a profesores y estudiantes y entrevistas a profesores. Los datos mostraron que, conforme aumenta la no presencialidad de las asignaturas, profesorado y estudiantado utilizaban más herramientas tecnológicas (correo electrónico, foro, chat, redes sociales...) para comunicarse. Además, el tipo de comunicación imperante tenía finalidades académicas, mientras que se producía una escasa interacción para aspectos más personales (de orientación, apoyo...); en este sentido, tanto profesorado como estudiantado preferirían un contacto más cercano no tan centrado en los elementos académicos del proceso. También observamos que en las asignaturas en línea se desarrolla un trabajo más individual por parte del estudiantado. Aunque todavía queda camino por recorrer en la interacción docente-discente a través de las TIC, los agentes implicados en el proceso reconocen sus potencialidades, pero aún no las utilizan como consideran que convendría hacerse.

Scaffolding through the network: analysing the promotion of improved online scaffolds among university students

This article explores how to enrich scaffolding processes among university students using specific Computer Supported Collaborative Learning –CSCL- software. A longitudinal case study was designed, in which eighteen students participated in a twelve-month learning project. During this period the students followed an instructional process, using the CSCL software to support and improve the students’ interaction processes, in particular the processes of giving and receiving assistance. Our research analyzed the evolution of the quality of the students’ interaction processes and the students’ learning results. The effects of the students’ participation in the CSCL environment have been described in terms of their development of affective, cognitive and metacognitive learning processes. Our results showed that the specific activities that students performed while working with the CSCL system triggered specific learning processes, which had a positive incidence on their learning results.

Analysing knowledge building: usages, achievements and limits of forums at university

This paper aims to explore asynchronous communication in computer supported collaborative learning (CSCL). Thirty virtual forums are analysed in both a quantitative and a qualitative way. Quantitatively, the number of messages written, message threads and original and answer messages are counted. Qualitatively, the content of the notes is analysed, cataloguing these into two different levels: on the one hand, as a set of knowledge building process categories, and on the other hand, following the scaffolds that Knowledge Forum offers. The results show that both an exchange of information and a collaborative work take place. Nevertheless, the construction of knowledge is superficial.

Time patterns and perceptions of online learning success factors

Online learning provides the opportunity to work on academic tasks at any time at the same time as doing other activities, such as using in web 2.0 tools. This study identifies factors that contribute to success in online learning from the students¿ perspective and their relationship with time patterns. A survey of learning outputs was used to find relationships between students¿ satisfaction, knowledge acquisition and knowledge transfer with time for working on academic tasks. In this study, 199 students from a university in Mexico completed the survey. Findings suggest that knowledge transfer has a significant association with the number of hours online per day, hours spent on social networks and the use made of e-learning during working hours. Learner satisfaction has a strong relationship with the time in years a learner has been using the Internet and the number of hours devoted to the course per week. The findings of this research will be helpful for faculty and instructional designers for implementing learning strategies.

The synchronization of personal information between mobile devices and online services by using SyncML

Monet henkilökohtaiset mobiililaitteet tarjoavat mahdollisuuden tallentaa henkilötietoja ja mahdollisuuden lyhyen kantaman radiotekniikoiden hyödyntämiseen. Vastaavasti henkilötietoja käyttävien tai vaativien verkkopalveluiden määrä on kasvussa. Mobiililaitteisiin tallennetut henkilötiedot tarjoavat potentiaalisen keinon välttää samojen henkilötietojen toistuva käsinsyöttö erilaisiin verkkopalveluihin ja keskitettyyn ajantasallapitoon. Tässä työssä käydään läpi ratkaisumalli henkilökohtaisen mobiililaitteen ja verkkopalveluiden välillä tapahtuvaan henkilötietojen siirtoon ja synkronointiin. Malli pohjautuu selainlaajennukseen, joka voi pyytää sekä selaimessa auki olevalta verkkopalvelun sivulta että mobiililta päätelaitteelta senhetkiset henkilötiedot ja synkronoida ne. Jo olemassaolevia henkilötietojen hallintaa helpottavia ratkaisuja käydään läpi arvioiden käyttökelpoisuutta tämänkaltaisiin tarpeisiin. Ratkaisumallin kannalta olennaiset tekniikat ja standardit, erityisesti Bluetooth ja SyncML, esitellään. Ratkaisumallin arkkitehtuuri käydään korkealla tasolla läpi ja esitellään toteutuksen yksityiskohtia. Tuloksena on periaatteeltaan kelvollinen henkilökohtaisten tietojen synkronointijärjestelmä, jonka toteutusta nykyisten mobiilien päätelaitteiden toiminnallisuus jossain määrin hankaloittaa.

Ilmakehan hiukkasmaisten ioniyhdisteiden online-mittaus

Ilmakehän hiukkaset aiheuttavat merkittäviä ympäristö- ja terveyshaittoja, joihin vaikuttaa hiukkasten kemiallinen koostumus. Hiukkasten kemiallisesta koostumuksesta voidaan hankkia tietoa hiukkasmittauksilla. Työn tavoitteena oli rakentaa jatkuvatoiminen mittausjärjestelmä, jolla voidaan mitata ilmakehän aerosolihiukkasten ionipitoisuuksia. Mittausjärjestelmä koostuu virtuaali-impaktorista, denuderputkista, PILS-laitteesta ja ionikromatografista. Näyteilmavirtaus kulkee ensin esierottimena toimivan virtuaali-impaktorm lävitse, joka poistaa aerodynaamiselta halkaisijaltaan 1,3 um:a suuremmat hiukkaset ilmavirtauksesta. Näyte, joka sisältää 1,3 um:a pienemmät hiukkaset kulkee virtuaali-impaktorin jälkeen kahden 1 % KOH-liuoksella käsitellyn denuderputken lävitse, joilla poistetaan hiukkasmääritystä häiritsevät happamat kaasut näytevirtauksesta. Denuderputkien jälkeen ilmavirtaus saapuu PILS-laitteeseen, jossa hiukkaset kasvatetaan vesihöyryn avulla aerosolipisaroiksi, törmäytetään keräyslevyyn ja sekoitetaan sen jälkeen sisäistä standardiainetta (NaBr) sisältavään kuljetusliuokseen. Kuljetusliuoksen ja aerosolipisaroiden seoksesta koostuva näyteliuos johdetaan PILS-laitteesta ionikromatografille analysoitavaksi. Mittausjärjestelmään liitetyllä ionikromatografilla voidaan analysoida neljä näytetta tunnissa. Näytteistä määritettävät anionit olivat sulfaatti, nitraatti ja kloridi. PILS-mittausjärjestelmää testattiin keräämällä hiukkasnäytteitä samanaikaisesti PILS-laitteella sekä virtuaali-impaktorilla tai suodatinkeräimellä ja vertaamalla saatuja aerosolihiukkasten sulfaattipitoisuuksia keskenään. Testeissa kerättiin joko VOAG-laitteella tuotettuja ammoniumsulfaattihiukkasia tai laboratorion huoneilmaa. PILS-mittausjärjestelmällä mitatut sulfaattipitoisuudet olivat 2-20 % pienempia kuin suodatinkeraimella mitatut, kun kerättiin keinotekoisesti tuotettuja ammoniumsulfaattihiukkasia. Huoneilmaa kerättäessä PILS-mittausjärjestelmällä saadut pitoisuudet olivat noin 10 % pienempiä kuin suodatinkeräystulokset. Koetulokset osoittivat, että mittausjärjestelmällä saadaan analysoiduksi luotettavasti hiukkasten sulfaattipitoisuudet.

What keeps female problematic internet users busy online?

While problematic Internet use is recognized to be predominant among male adolescents, a female trend is gradually becoming apparent. Our study aimed at investigating the characteristics of female Internet users and distinguishing between the online activities of problematic and regular Internet users' on school days. Data were retrieved from a cross-sectional survey of a representative sample of 3067 8th graders in the canton of Vaud, Switzerland, that completed an online questionnaire in 2012. Only females were included. Based on the Internet addiction test, the sample was divided into regular (RUs) (IAT < 50, n = 1339) and problematic users (PIUs) (IAT ≥ 50, n = 201). Groups were compared regarding sociodemographic variables, online activities, devices used to access the Internet, substance use, and physical activity. Significant variables were included in a backward logistic regression. At the multivariate level, PIUs were more prone to spend time online for leisure activities (odds ratio [OR] 2.38) and to access the Internet through a smartphone (OR 1.79) or tablet (OR 1.84). PIUs were less likely to be physically active (OR 0.86) and more likely to present poor emotional well-being (OR 2.67) and to smoke (OR 1.88). CONCLUSION: A sizeable percentage of female adolescents are problematic Internet users. When performing a comprehensive biopsychosocial assessment, teenagers owning numerous devices to access the Internet, presenting other health-compromising behaviors or poor emotional well-being should be specifically targeted. WHAT IS KNOWN: ? Problematic Internet use has been found to be predominant among males. ? Specific online activities have been identified as being addictive for young men and women differently. ? Problematic Internet use is known to impact in several ways the general health and daily functioning of teenagers. What is New: ? A sizeable percentage of female adolescents are problematic Internet users. ? Tobacco use, poor well-being, as well as compact devices to access the Internet are positively related to problematic Internet use. ? In addition to their special interest in online social and communicational activities, female problematic Internet users also reported more online gambling.

Online brands: Branding, possible worlds, and interactive grammars

This paper proposes to reflect from a semiotic perspective on the transformation that brands have undergone since the rise of the Internet. After a brief theoretical introduction to digital communication and the semiotics of brands, the case of the Google brand is analyzed by applying concepts of generative and interpretive semiotics. The paper holds that the iconic and linguistic enunciations are secondary with respect to interaction. In digital media interaction — the interactive experience that the Internet user lives — is a fundamental component of the hypermedia cocktail and occupies a central position in the brand building process. The article concludes with some of the questions and special characteristics raised by so-called eBranding.

Online drawings for dementia diagnose: in-air and pressure information analysis

In this paper we present experimental results comparing on-line drawings for control population (left and right hand) as well as Alzheimer disease patients. The drawings have been acquired by means of a digitizing tablet, which acquires time information angles and pressures. Experimental measures based on pressure and in-air movements appear to be significantly different for both groups, even when control population performs the tasks with the non-dominant hand.
