Beyond the Test of the Four Channel Model of Flow in the Context of Online Shopping

In this study we investigate the effects of user skill and task challenge on online shoppers’ experiences. We use a model suggested by flow theory in which shoppers are grouped into four categories (flow, anxiety, boredom, and apathy) based on their perceptions of task challenge and their skill in performing an online shopping task. Results show that anxious shoppers have lower perceptions of the dimensions of flow, believe online shopping Web sites are less useful, and believe they are less likely to use the system in the future compared to the other three groups of online shoppers. In addition to challenge and skill, having a clear goal and fast feedback also contribute to the flow experience.

An Examination of the Effects of Flow on Learning in a Graduate-Level Introductory Operations Management Course.

The authors investigated the effects of flow on learning outcomes in a graduate-level operations management course. Flow was assessed through an overall flow score, four dimensions of flow, and three characteristics of flow activities. Learning outcomes were measured objectively through multiple-choice quiz scores and subjectively using measures of students’ perceived learning of the subject matter, students’ perceived skill development, and student satisfaction. The findings show that flow affected students’ perceived learning of the subject matter and student satisfaction but did not affect learning performance as measured through multiple-choice quizzes. Partial support is found for an effect of flow on students’ perceived skill development.

An examination of the information quality perceptions of Mexican internet users

Mexico was a relatively early adopter of the internet, and although broadband access has been limited in some parts of the country, the government has aggressively sought to provide internet access to users throughout the country. This study reports the results of a study of perceptions of information quality among Mexican users of the internet. Results are reported from a survey of internet users at two Mexican universities in which perceptions of 15 dimensions of information quality are assessed. The nine dimensions of believability, accuracy, objectivity, reputation, value-added, ease of understanding, representational consistency, concise representation, and access security have higher ratings for traditional text sources of information than for internet sources of information. In contrast, the dimensions of timeliness and accessibility have higher ratings for internet sources than for traditional text sources of information.

A longitudinal study of user perceptions of information quality of Chinese users of the internet

More than a half billion people use the internet in China, and the environment in which these users work, study, and play using the internet is a rapidly changing one. User perceptions of the quality of information accessed through the internet and through more traditional sources of information may shift over time as the underlying social, cultural, and political environment changes. This study reports the results of a longitudinal survey study of perceptions of information quality of young adults using the internet in China. Results suggest that perceptions of the information quality of internet-based information have shifted more from 2007 to 2012 than perceptions of traditional text sources of information. Implications of the findings for researchers, educators, and information providers are discussed.

The case of flow and learning revisited

ABSTRACT Many business schools are criticized for being ineffective in helping students learn proper management skills and knowledge. Flow theory has been cited as being helpful in many learning environments in that flow experience can enhance student learning. The authors conducted a study of 315 students in an undergraduate operations management (OM) class to assess learning outcomes and flow experience. Results show that student learning performance and flow are related. Implications and suggestions for further research are provided.

Analysis of structure importance of compensation capacitor in jointless track circuit

This paper models the input signal amplitude of the main track and the small track of the adjacent jointless track circuit (JTC) when JTC is idle and the track circuit reader(TCR) received signal amplitude when JTC is occupied, based on the work mechanism of JTC and TCR. Based on the models, the relative impact of compensation capacitor on signal amplitude is obtained by simulation. The paper further proposes a calculation method for structure importance of compensation capacitors. Experimental results indicate that the rankings of structure importance are not affected by ballast resistance of JTC in this method. The results also show that the compensation capacitors closer to the receiving end are more important than those closer to the sending end. In addition, C2, C6, and C3 closer to receiving end are the most important and should be paid close attention during maintenance. The second, the first and the fifth capacitor from the sending end, have less impact on the JTC and TCR signal. This paper is helpful to determine the maintenance priority of each capacitor, optimize the maintenance strategy, and make better use of JTC.
