Re-evaluating trust and privacy concern when purchasing a mobile app: Re-calibrating for the increasing role of Artificial Intelligence
No full textMobile apps utilize the features of a mobile device to offer an ever-growing range of functionalities. This vast choice of functionalities is usually available for a small fee or for free. These apps access the user’s personal data, utilizing both the sensors on the device and big data from several sources. Nowadays, Artificial Intelligence (AI) is enhancing the ability to utilize more data and gain deeper insight. This increase in the access and utilization of personal information offers benefits but also challenges to trust. Using questionnaire data from Germany, this research explores the role of trust from the consumer’s perspective when purchasing mobile apps with enhanced AI. Models of trust from e-commerce are adapted to this specific context. A model is proposed and explored with quantitative methods. Structural Equation Modeling enables the relatively complex model to be tested and supported. Propensity to trust, institution-based trust, perceived sensitivity of personal information, and trust in the mobile app are found to impact the intention to use the mobile app with enhanced AI
The second extended model of consumer trust in cryptocurrency payments, CRYPTOTRUST 2
No full textCryptocurrencies’ popularity is growing despite short-term fluctuations. Peer-reviewed research into trust in cryptocurrency payments started in 2014. While the model created then, is based on proven theories from psychology and supported by empirical research, a-lot has changed in the past 10 years. This research finds that the original model is still valid, but it is extended to capture the current situation better. A quantitative methodology is used to validate the updated model proposed. The results from the quantitative survey show that (1) personal innovativeness in technology and (2) finance, influence (3) disposition to trust. Disposition to trust influences six variables from the specific context of the payment. Three variables related to the cryptocurrency itself are (4) stability in the value, (5) transaction fees, and (6) reputation. Institutional trust is influenced by (7) regulation, and (8) payment intermediaries. The last contextual factor is (9) trust in the retailer. The six variables from the context influence (10) trust in the payment which, finally, influences (11) the likelihood of making the cryptocurrency payment
Investigating the individual trust and school performance in semi-virtual collaboration groups
No full textPurpose: the purpose of this paper is to investigate the relationship between individual trust of students in computer supported semi-virtual collaboration groups and student’s performance in school. Design/methodology/approach – Longitudinal questionnaires and interviews are conducted during the case study. By analyzing the data from the questionnaires and the grade earned by the students, the sample students are ranked with respect to the trust level and individual performance. Furthermore, the Wilcoxon signed-rank test is used to compare individual trust level and performance in the computer supported semi-virtual collaborative environment.Findings: the distribution of an individual’s trust level is roughly consistent with the distribution of the individual’s performance in the collaboration. Besides, the relationship between a student’s trust level and the student’s performance is positively correlated.Research limitations/implications: this study integrates the issues of trust, school performance, and collaboration in an educational context. Furthermore, the conclusions drawn from this paper extend the literature of multiple disciplines including education, management, and psychology.Practical implications: the conclusions could apply in the fields of education and management since the analysis revealed the relationship between an individual’s trust level and their performance. Originality/value – This study contributes to the field of trust and collaboration research with a link to trust development and performance. The study also provides an insight into how to successfully improve the performance of student semi-virtual collaboration groups.<br/
Investigating individual trust in semi-virtual collaboration of multicultural and unicultural teams
No full text© 2016 Elsevier Ltd. All rights reserved. This study aims to investigate individual's trust development for semi-virtual collaboration teams with multicultural and unicultural background. We aim to explore whether the trust levels in multicultural and unicultural semi-virtual groups will be the same, how trust develops over time and what the corresponding factors to the trust development are. In order to answer the questions, a longitudinal case study was conducted in unicultural and multicultural teams. We have taken survey for 144 participants over three stages, as well as interviewed 64 participants. Results of the analysis of the survey data firstly show that no significant difference exists between multicultural and unicultural groups. Then, two factors, collaboration process and clear task help explain this phenomenon. However, the trust development of multicultural groups shows instability and keeps decreasing over time, while unicultural groups behave differently. We found that language, values and habitual behavior lead to the differences in these two types of groups
Fu Describing About the Author Himself: A Focus on Ban Gu "You tong fu"
No full textFrom Later Han dynasty onwards, the number of fu describing about the author himself has increased. There are several possible reasons for this, but the most important reason is probably that there was no other genre through which one could express oneself except for fu in this period. For instance, the fiveword poetry was still in the middle way of establishing its own style at that moment. Moreover, in Former Han, there were few opportunities for authors to talk about themselves in detail in fu, because the main readers were emperors and kings of countries. In Later Han, the readers had become more diverse. That is probably the reason why more fu began to mention about the authors themselves in this period. Ban Gu (32-92), who is a representative scholar of Later Han and also a man of letters, expressed his aim by writing "You tong fu". Its main content is that though one's encounter with a disaster or felicity is not always derived from our behavior, we have to have a strong will and take action to overcome disasters. This idea is supported by Ban Gu's experiences of not attaining his aim. Such experiences are common in Chinese authors. One of the earliest examples is Chu Ci. Also, Chu Ci is the one of the origins of fu. It is surprising that authors expressed things about themselves mostly in fu describing journeys. It may be easier to understand this tendency if we think they substituted the heaven wander in Chu Ci with a ground journey. Chu Ci was a model for authors to express their aim which could not come true, even if the journey on the ground and the wander in heaven are different
Online Iterative Adaptive Dynamic Programming Approach for Solving the Zero-Sum Game for Nonlinear Continuous-Time Systems with Partially Unknown Dynamics
No full textThe current study presents an online iterative adaptive dynamic programming approach to resolve the zero-sum game (ZSG) for nonlinear continuous-time (CT) systems containing a partially unknown dynamic. The Hamilton-Jacobian-Issacs (HJI) equation is solved along the state trajectory according to the value function approximation and the policy improvement online. Relaxed dynamic programming is utilized to ensure the algorithm’s convergence. Model and costate networks were established to conduct the method. Computational simulations are performed to present the efficiency of the algorithm.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Control & Simulatio

Practical application of on-line partial discharge monitoring technique on 500kV shunt reactor
No full textConsidering the damage mechanism of oil-impregnated paper insulation in power transformers, shunt reactors and other high voltage electrical apparatus caused by partial discharge, a concept of “destructive partial discharge” is introduced in this paper. The intensity of this discharge is regarded as several thousands pico-coulomb (pC) and may cause the insulation a fatal damage. An oil-paper insulation is usually able to withstand this type of partial discharge for a period of time prior to failure. This provides engineers a time window to detect it. This paper describes an on-line partial discharge monitoring system for 500kV shunt reactors. The commission results from 3 single-phase shunt reactors either connected or disconnected to the grid showed that the on-line partial discharge detecting system has a high noise immunising ability. Two years later after the installation, a pre-warning signal was received from one shunt reactor indicating the existence of an intermittent discharge. The acoustic emission system located its position at the low end of the high voltage bushing in the oil. Dissolved gasses analysis (DGA) in the oil suggested the presence of partial discharge, as acetylene (C2H2) was as high as 20ppm. PD activity was further confirmed by a physical examination on the reactor
Lu Yu and Tu Fu
No full textLu Yu 陸游 (1125-1209), the famous patriot poet of the Southern Sung, admired Tu Fu above all the poets of the past, and the deep influence which Tu Fu exercised on him may be seen throughout his work. In spite of this fact, however, there are many differences which mark the lives and works of the two men. As a first step towards a comparative study of the two poets, the author has attempted to discover how Lu Yu evaluated his predecessor, using evidence found in Lu Yu's poems themselves. By Lu Yu's time, Tu Fu was already widely recognized as the greatest Chinese poet. It had become a popular pastime to try to identify individual poems of Tu Fu on the basis of isolated phrases or couplets, or to compose poems made up of clever imitations of various couplets of Tu Fu. But Lu Yu, unlike most of his contemporaries, was less attracted by Tu Fu's poetic technique than by his poetic spirit, and regarded the latter as the most valuable lesson to be learned. He insisted that it was Tu Fu the man rather than Tu Fu the poet, Tu Fu the patriot rather than Tu Fu the artist, who deserved to be most highly admired. This was the foundation upon which Lu Yu's evaluation of Tu Fu rested, and the premise upon which he approached his work
