Key drivers of internet banking services use

2009

PurposeThe purpose of this paper is to analyse the determinants of internet banking use, paying special attention to the role of product involvement, perceived risk and trust.Design/methodology/approachThe impact of trust, perceived risks, product involvement and TAM beliefs (ease of use and usefulness) on internet banking adoption is tested through structural equation modelling techniques. The sample consists of 511 Spanish internet banking services users and the data are collected through an internet survey. Risk is measured as a formative construct.FindingsData analysis shows that TAM beliefs and perceived risks (security, privacy, performance and social) have a direct influence on e‐ban…

How Can Secure Websites Improve Buying Intention?

2014

A conceptual model is proposed to show 3 effects of augmenting security perceptions (more pleasure, less perceived risk and higher trust) in order to improve buying intention. The role of usability in reinforcing these direct and indirect security effects has also been tested. This study examines the reinforcement of previous relationships in highly usable contexts. To test this, a fictitious website was designed for a nonexistent clothing company directed at the segment of middle class consumers. Two blocks of changes were made to alter website usability: one concerning website speed and the other related to ease of use. Results for a study sample of 170 respondents show that in usable con…

Key drivers of consumer loyalty to Facebook fan pages

2014

Purpose – With the rapid expansion of social networking sites, researchers and practitioners are challenged to understand drivers of customer loyalty in fan pages. The purpose of this paper is to identify the main drivers of Facebook fan page loyalty in order to promote the creation of affective links and long-term relationships with users. Design/methodology/approach – The impact of trust, fan page content dependency, attitude and consumer beliefs on loyalty to fan pages was tested through structural equation modelling techniques. The sample consisted of 691 Spanish Facebook users. Findings – Data analysis shows that attitude appears as a key variable in increasing loyalty to fan pages. T…

Identity in virtual communities

1998

The usability of Collaborative Virtual Environments is a function of technical affordances with the implicit and explicit intentions of users. Intentions can be revealed by 'cyborg ethnography' -- a close examination of interactions and conversations conducted in CVE's. Three CVE's were examined ethnographically and it is found that social conventions develop around the theme of producing identity. However, there is doubt that such conventions constitute evidence of a 'virtual' social system.

Developing empowering health counseling measurement

2006

Abstract Objective This article describes the derivation of an instrument (Empowering Speech Practices Scale) for assessing the empowerment of dyadic counseling, the evaluation of the validity and reliability of the ESPS and the results acquired with the instrument from hospital counseling. Methods ESPS was constructed on the basis of empowerment theory and foregoing conversation analytic research. Nurses and patients assessed the same counseling session by way of parallel statements. Structure and reliability of the scale were evaluated with Cronbach alpha, percentage of agreement, factor analysis and logistic regression analysis. Results According to these preliminary results, ESPS descri…

Recent Applications of Carbonaceous Nanosorbents in Solid Phase Extraction for the Determination of Pesticides in Food Samples

2018

This article covers recent trends of carbonaceous nanomaterial supported solid phase extraction for the liquid and gas chromatography analysis of pesticides in food samples. Several advanced carbonaceous nanosorbents have been reported over the previous decade for pesticide extraction, such as graphene derivatives modified by combination with silica, amines, polymers, and/or magnetic nanoparticles. The advances in this field have opened possibilities for using neat or modified carbon nanotubes or graphene-type sorbents for the pre-concentration of polar or nonpolar pesticides by solid phase extraction (SPE) or micro-SPE methods or to apply such nanomaterials for the removal of matrix compon…

Psychiatrists' Attitudes Toward Disruptive New Technologies: Mixed-Methods Study

2018

Background Recent discoveries in the fields of machine learning (ML), Ecological Momentary Assessment (EMA), computerized adaptive testing (CAT), digital phenotype, imaging, and biomarkers have brought about a new paradigm shift in medicine. Objective The aim of this study was to explore psychiatrists’ perspectives on this paradigm through the prism of new clinical decision support systems (CDSSs). Our primary objective was to assess the acceptability of these new technologies. Our secondary objective was to characterize the factors affecting their acceptability. Methods A sample of psychiatrists was recruited through a mailing list. Respondents completed a Web-based survey. A quantitative…

Aesthetic Appeal and Visual Usability in Four Icon Design Eras

2016

Technological artefacts express time periods in their visual design. Due time, visual culture changes and thus affects the design of pictorial representations in technological products, such as icons in user interfaces. Previous research of temporal aspects in human-computer interaction has been focusing on particular interaction situations, but not on the effects of design eras on user experience. The influence of icon design styles of different eras on aesthetic and usability experiences was studied with the method of primed product comparisons. Affective preferences and their processing times were analysed in order to examine visual usability in terms of semantic distance and aesthetic a…
