An Acceptance Model for Useful and Fun Information Systems
2006
Investigating the factors associated with user acceptance of new software systems has been an important research stream in the field of information systems for many years. The technology acceptance model has long been used to examine the acceptance of utilitarian systems. Recently, it has been used to examine recreational or pleasure-oriented systems. Many examples exist of software that, depending on the context of use, can be used for productive and pleasurable interaction. This paper examines the determinants of use of one such “dual” system. A survey of users of a dual system was conducted. Results show that perceived usefulness is more important in determining intention to use than per…
Revista electrónica de investigación y evaluación educativa

La victimización en la escuela representa un fenómeno preocupante dado las consecuencias negativas que se le asocian, como son estados de depresión o ansiedad, los cuales guardan relación con los hábitos de ocio digital. Se realizó un estudio descriptivo de tipo transversal, realizado en una muestra de 1038 escolares de tercer ciclo de Educación Primaria (M = 11,33; DT = 1,27), el cual persigue como principal objetivo contrastar un modelo explicativo del uso de televisión y videojuegos en función de la victimización. Se emplearon como principales instrumentos la Escala de Victimización en la Escuela (Mynard y Joseph, 2000), el Cuestionario de Experiencias Relacionadas con Videojuegos (Chama…
Analysis of the perceived self-‐efficacy in the use of ICT of pre-‐ service primary and preschool teachers
2017
La formación del profesorado en el uso de las TIC es un aspecto importante para conseguir una verdadera integración de las TIC en la educación. Según el modelo TPACK, esta formación no debe limitarse a contemplar de manera separada los aspectos relacionados con las TIC, el contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que…

Consensus modelling and molecular dynamics studies for the identification of novel telomerase inhibitors as anti-cancer agents
2018
Telomerase plays an important role in early stages of life-maintaing telomere and chromosomal integrity of frequently dividing cells. It turns dormant in most somatic cells during adulthood. However, in cancer cells, telomerase gets reactivated and works tirelessly to maintain the length of telomeres, leading to immortality of cells. Hence, in this study, we have used a combined ligand-based and structure based drug design approach for the identification of novel telomerase inhibitors as anti-cancer agents. We have generated ligand-based QSAR models and structure-based pharmacophores models, according our recent MYSHAPE approach (1), and validated exhaustively. The validated models were use…
Akadēmisko bibliotēku telpu salīdzinājums
2018
Bakalaura darbā “Akadēmisko bibliotēku telpu salīdzinājums” tiek salīdzinātas un pētītas trīs akadēmiskās bibliotēkas – Rīgas Stradiņa Universitātes bibliotēka, Latvijas Universitātes dabaszinātņu bibliotēka un Biznesa Augstskolas “Turība” bibliotēka – tiek noskaidrots šo bibliotēku iekārtojums, telpu sadalījums, piemērotība, estētiskums un ērtība. Pētnieciskā darba mērķis ir uzzināt galvenos akadēmisko bibliotēku telpu priekšrocības un to trūkumus, salīdzinot to ar Dānijā izstrādāto četru telpu modeli. Pētījuma laikā noskaidrojās bibliotēku lietotāju viedokļi un izteikti ieteikumi, ko akadēmiskajām bibliotēkām vajadzētu ieviest. Darba autores izvirzītā hipotēze pētījuma galā apstiprinājās.…
On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams
2018
Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
LA PERCEZIONE DEL TEMPO
2005
This paper reviews psychological research on time perception. In view of the wastness of this topic, we only focus on temporal memory, i.e. time duration estimation. We will present the main psychological theories, elaborated in the first laboratories.Finally, both the current cognitivist and chronobiological models and theories will be introduced.
