Adicción a la pornografía: interferencia atencional y gravedad del consumo

2019

Introducción: El aumento del uso de las Tecnologías de la Información y la Comunicación (TICS) e Internet en nuestra sociedad ha potenciado la aparición de nuevas formas de adicción. Una de las más relevantes por sus implicaciones sociosanitarias sería la adicción al cibersexo, y más en concreto, el visionado excesivo de pornografía online. Numerosos estudios apuntan que, en determinadas personas, el visionado de pornografía puede sobrevenir excesivo e incontrolado, generando graves problemas en las diferentes áreas de la vida. Por ello, es importante explorar aquellos factores que actúan como predisponentes o mantenedores de este problema. Se postula que uno de ellos podría ser la capacida…

Theta and gamma oscillations in the rat hippocampus during attentive lever pressing

2018

AbstractThe hippocampus is known to be pivotal for spatial memory but emerging evidence suggests its contribution to temporal memories as well. However, it is not clear how the hippocampus represents time and how it synchronizes spatial and temporal presentations into a coherent memory. We assessed the specific role of hippocampal theta and gamma oscillations and their interaction in short-term timing of motor reactions. Rats were trained to maintain lever pressing for 2.5 s and then to quickly release the lever and retrieve water reward from a nearby water port guided by a cue light. In essence, this task allows observation of hippocampal rhythms during timed anticipation when no overt mov…

E-wave and heart rate responses during anticipation of nonmotor events.

1994

This study concentrated on three main questions: 1) can anticipatory late negative shift (expectancy wave, E-wave) be elicited in nonmotor S1-S2 paradigm, 2) is it sensitive to variation of emotional aspects of the task and 3) is there a connection between heart rate (HR) responses and E-wave. S1 was a letter row that was replaced tachistoscopically by another letter row (S2). The task of the subjects (n = 12) was to detect if the critical aspects of S2 were similar to S1. After their delayed response they received feedback of their performance. The emotional aspects of the task were varied by presenting aversive noise bursts at the end of the feedback period either always, contingently to …

The Role of Task Values in Adolescents' Educational Tracks: A Person-Oriented Approach

2009

The present study examined what kinds of patterns of task-values adolescents show, and whether these patterns predict their educational and occupational expectations and school track. Six hundred and fourteen adolescents were examined twice before their transition to secondary education and once thereafter. The clustering-by-cases analyses identified 6 groups: (1) those who placed a high value on all school subjects, (2) those who did not value any of the subjects, (3) those who valued Finnish and social sciences, (4) those who valued in particular practical and art subjects, (5) those who valued only practical and art subjects, and (6) those who especially valued mathematics and science. T…

East Asia in the Global Economy: Theoretical and Empirical Questions for Marxism

2019

As Marxism and socialism pass through watershed years it is important to reflect on the abiding questions of Marxist theory and empirical analysis. This article takes up this task in the context of East Asia under the impetus of globalisation and neo-liberalism, introducing a collection of five articles collected in the special issue. The article shows that questions Marx posed about the global economy more than a century ago remain prescient and continue to animate cutting-edge research, as shown in the articles in this special issue.

Reading literacy in Compulsory Secondary Education: an exploration of the difficulties in the use of information to answer questions / La competencia…

2014

AbstractThis paper is a review of studies about processes and secondary school students’ difficulties with these processes when they use information to answer questions. The PISA program uses this kind of task-oriented reading situation to evaluate reading literacy, which is also a common reading situation in educational settings. Four key strategies are identified to successfully perform this kind of task: decide how to read the information, comprehend the task, decide when to search for information in order to solve the task, and self-regulate that search process. Moreover, this paper provides accurate information about the students’ difficulties in becoming skilled readers when they use …

Study and Evaluation of Pre-trained CNN Networks for Cultural Heritage Image Classification

2021

The classification of digital images is an essential task during the restoration and preservation of cultural heritage (CH). In computer vision, cultural heritage classification relies on the classification of asset images regarding a certain task such as type, artist, genre, style identification, etc. CH classification is challenging as various CH asset images have similar colors, textures, and shapes. In this chapter, the aim is to study and evaluate the use of pre-trained deep convolutional neural networks such as VGG16, VGG-19, ResNet50, and Inception-V3 for cultural heritage images classification using transfer learning techniques. The main idea is to start with CNN models previously t…

2020

Abstract Information technology (IT) engagement is defined as a need to spend more time using IT. Practice-based examples show that IT engagement can have adverse effects in organizations. Although users can potentially get more work done through IT engagement, observations show that the users might jeopardize their well-being and hamper their work performance. We aimed to investigate this complexity in the research on IT engagement by examining its potential antecedents and outcomes in organizations. Considering the potentially mixed outcomes, we developed a model to examine the effects of IT engagement on personal productivity and strain. We also aimed to explain the antecedents of IT eng…

Social Network Banking : A Case Study of 100 Leading Global Banks

2018

Social media is widely recognized as a challenging new communication technology in both economic and social contexts. The present article explores how banks have exploited this technology in the range of consumer retail banking services offered by 100 leading global banks on the three major social networking sites (SNS): Facebook, Twitter, and YouTube. Viewing social network (SN) banking as a separate delivery channel and offering a working definition of SN banking, the article shows that banks have been more cautious than other businesses in using SNS. The available services are classified on nine main dimensions: marketing, financial education and advice, information support, customer sup…

Measuring the antecedents of e-loyalty and the effect of switching costs on website

2010

This paper deals with the process by which electronic customer loyalty (e-loyalty) is formed. The twofold aim is to analyse e-loyalty, describing its development in terms of how it is influenced by several determinants and to study potential barriers to switching which significantly affect the repeat purchase decision. In particular, an integrating theoretical framework is proposed to determine the e-loyalty dependency of electronic service quality and perceived value, and how this last relationship can be moderated by switching costs. Results offer evidence for the important role of customer's perceptions of e-service quality and value in e-loyalty. Proposals are made of how companies that…
