Nudging to prevent the purchase of incompatible digital products online: An experimental study.
2017
Ensuring safe and satisfactory online shopping activity, especially among vulnerable consumers such as elderly and less educated citizens, is part of a larger set of consumer policy objectives seeking to strengthen trust in the electronic marketplace. This article contributes to that goal by testing the effectiveness of nudges intended to prevent the purchase of 'incompatible' digital products (i.e., those which cannot be used with the devices owned by consumers or the systems they operate). We ran a computerised lab experiment (n = 626) examining three types of nudges, the effects of age and education, and interaction effects between these variables and the nudges. Results show that emotiv…
BENEFITS OF MULTI-DOMAIN FEATURE OF MISMATCH NEGATIVITY EXTRACTED BY NON-NEGATIVE TENSOR FACTORIZATION FROM EEG COLLECTED BY LOW-DENSITY ARRAY
2012
Through exploiting temporal, spectral, time-frequency representations, and spatial properties of mismatch negativity (MMN) simultaneously, this study extracts a multi-domain feature of MMN mainly using non-negative tensor factorization. In our experiment, the peak amplitude of MMN between children with reading disability and children with attention deficit was not significantly different, whereas the new feature of MMN significantly discriminated the two groups of children. This is because the feature was derived from multi-domain information with significant reduction of the heterogeneous effect of datasets.
Socio-demographic, health-related, and individual correlates of diagnostic self-testing by lay people: Results from a representative survey in Germany
2017
Introduction A broad range of self-tests (testing for e.g. HIV, cancer, hepatitis B/C) have become available and can be conducted by lay consumers without the help of a health professional. The aims of this study were to (a) investigate the prevalence of self-testing, (b) identify the most frequently used self-tests, and (c) explore the associations between socio-demographic, health-related and individual factors with self-testing. Methods A face-to-face plus paper-pencil cross-sectional survey was conducted. The sample consisted of 2.527 respondents who were representative of the German population in terms of the age, sex, and residence. Basic descriptive statistics and univariate logistic…
Message-driven factors influencing opening and forwarding of mobile advertising messages
2015
This work aims to analyse the influence of message-driven factors -informativeness, ubiquity, frequency and personalization- on consumer attitude and behaviour -opening and forwarding- towards mobile advertising messages. A theoretical model was developed and empirically tested using a sample of 355 Spanish teenager mobile users. Findings show that frequency is the dimension accounting the most -and significantly- of the four message-driven factors analysed on attitude toward mobile advertising. Attitude has a significant effect on acceptance of mobile advertising messages. Message-driven factors – in a direct way and indirectly through attitude toward mobile - lead to consumer opening and …
The Role of Individual-Media Relationship and Consumer Personal Factors on Spanish Teenagers' Mobile Social Networking Sites Usage
2014
Social Networking Sites (SNS) are gaining momentum as powerful tools of marketing communications. Mobile phones are becoming one of the most popular devices for accessing Social Networking Sites. In Spain, 44% of Social Networking Sites users access these sites on a daily basis while 79% of them access these sites on a weekly basis. Furthermore, it is notable that over 70% of Social Networking Sites users talk about and recommend commercial brands. This justifies the interest of the study of Social Networking Sites users from a marketing perspective. The aim of this research is to assess the influence of consumers` personal factors (attitude, innovativeness and gender) and individual-media …
Intercultural communication: Where we’ve been, where we’re going, issues we face
2015
The purpose of this review is to critically analyze the state of intercultural communication literature. This review has three purposes. First, this review summarizes where the discipline has been, paying close attention to the discipline’s history and some key areas of research. Second, this review discusses where the discipline is going, with an emphasis on how the discipline is expanding into new contextual areas of research. Finally, the review presents challenges, issues, and areas for future discussion for intercultural communication.
Employee Information Security Practices: A Framework and Research Agenda
2020
Author's accepted manuscript Employee information security practices are pivotal to prevent, detect, and respond to security incidents. This paper synthesizes insights from research on challenges related to employee information security practices and measures to address them. The challenges identified are associated to idiosyncratic aspects of communities and individuals within organizations (culture and personal characteristics) and to systemic aspects of organizations (procedural and structural arrangements). The measures identified aim to enhance systemic capabilities and to adapt security mechanisms to the idiosyncratic characteristics and are categorized as: (a) measures of training an…
Business models of FinTechs – Difference in similarity?
2021
Abstract The FinTech industry is gradually maturing and offers a wide range of financial services on the global stage. Still, the understanding of FinTech business models remains at its infancy with a shortage of cross-country comparisons. This paper aims to determine the differences in business model attributes of FinTechs in five rapidly emerging FinTech hotspots in Central and Eastern Europe (CEE). Survey results from Estonia, Latvia, Lithuania, Poland, and Russia, accompanied by cluster analysis, enable us to provide unique in-depth evidence on FinTech business models. Across the selected countries, we observe significant differences in the attributes of FinTech business models: key act…
Transaction management for m-commerce at a mobile terminal
2006
Although there has been a lot of discussion of "transactions" in mobile e-commerce (m-commerce), very little attention has been paid for distributed transactional properties of the computations facilitating m-commerce. In this paper, we first present a requirement analysis and then present a wireless terminal-based transaction manager (TM) architecture. This architecture is based on the assumption that there is an application that supports certain business transaction(s) and that it uses the TM to store transactional state information and retrieve it after a communication link, application, or terminal crash. We present the design of such a TM, including the application interface, modules a…
Activity of the Elderly in an Eight-Week Case Study
2015
This study explores the engagement of the elderly with a new health-enhancing mobile-optimised web-service: An eight-week case study was carried out. Participants of the study were elderly people: 45 females and 19 males with the average age of 72.3 (SD 5.2) years. Their baseline information and communication technology experiences were evaluated, the data of using each service component was saved to a server and the usability of the service was evaluated. The majority of the users remained active throughout the study. The most frequently used components in the study were memory puzzles and physical exercise. The usability of the components was correlated with the age of the participants. T…
