Abstract

Purpose

This paper aims to reports the further developments of an optical sensing technique, relying on Mie scattered and reflected light, from the ice surface and volume, to determine the ice accretion rate as well as the ice type.

Design/methodology/approach

By measuring the optical intensity of the backscattered and reflected light, the paper demonstrates that it is possible to obtain information on the onset of icing as well as determine the thickness and type of ice accreted on the leading edge of a wing in real time.

Findings

This work is important in the design and development of optical direct ice detection sensors for aerospace applications.

Practical implications

This work is aimed at showing a new approach to ice detection.

Originality/value

Abstract

Purpose

The purpose of this paper is to identify the factors influencing the growth of healthcare virtual communities of practice (VCoPs) through a seven-year longitudinal study conducted using metrics from social-network and semantic analysis. By studying online communication along the three dimensions of social interactions (connectivity, interactivity and language use), the authors aim to provide VCoP managers with valuable insights to improve the success of their communities.

Design/methodology/approach

Communications over a period of seven years (April 2008 to April 2015) and between 14,000 members of 16 different healthcare VCoPs coexisting on the same web platform were analysed. Multilevel regression models were used to reveal the main determinants of community growth over time. Independent variables were derived from social network and semantic analysis measures.

Findings

Results show that structural and content-based variables predict the growth of the community. Progressively, more people will join a community if its structure is more centralised, leaders are more dynamic (they rotate more) and the language used in the posts is less complex.

Research limitations/implications

The available data set included one Web platform and a limited number of control variables. To consolidate the findings of the present study, the experiment should be replicated on other healthcare VCoPs.

Originality/value

The study provides useful recommendations for setting up and nurturing the growth of professional communities, considering, at the same time, the interaction patterns among the community members, the dynamic evolution of these interactions and the use of language. New analytical tools are presented, together with the use of innovative interaction metrics, that can significantly influence community growth, such as rotating leadership.

Abstract

Purpose

Drawing upon the literature of Uses and Gratifications (U & G) Theory, the purpose of this paper is to propose that entertainment, information seeking, socialization, and self-presentation are the motivational factors affecting continuance intention of social media. This paper further investigates the moderating effects of cultural difference and socio-economic status on the link between these motivational factors and continuance intention.

Design/methodology/approach

Data collected from the 493 active users of Facebook in five countries (Australia, Austria, Japan, Taiwan, and the USA) were used to test the proposed model. Partial least squares method was used to assess the relationships in the model and the subgroup analysis method was employed as well to examine the moderating roles of cultural difference and socio-economic status.

Findings

Information seeking exerts stronger effect on continuance intention for users from individualistic cultures, while socialization, and self-presentation has stronger influence on continuance intention for users from collective cultures. Entertainment has stronger influence on continuance for high educated users, whereas self-presentation has stronger influence on continuance intention for users with lower level of education. Finally, the effect of entertainment, information seeking on continuance intention is stronger for users with higher level of income, while self-presentation has stronger influence on continuance intention for users with lower level of income.

Originality/value

This study is one of first studies to extend the research context of U & G Theory from adoption of social media to continuance intention of social media. This study is also the first to investigate the moderating roles of cultural difference and socio-economic statuses in social media usage behavior simultaneously.

Abstract

Purpose

The purpose of this paper is to explore the relationships among cognitive-based trust, affect-based trust, sense of belonging, self-image congruity, perceived community-brand similarity, and information intention by applying the uses and gratification (U&G) theory and the dual mediating hypothesis in the context of Taiwanese social networking brand sites.

Design/methodology/approach

This study uses specific metrics to measure construct items. The respondents have used or currently use the Facebook Apple fan page for more than three months. This study conducts the online survey of mySurvey through the website and provides respondents with convenience store coupon rewards to increase the response rate. This study collects 500 samples with 381 valid samples and uses a structural equation modeling to test the research hypotheses.

Findings

The effects of cognitive-based trust on psychological factors are higher than the effects of affect-based trust on psychological factors. In addition, cognitive-based trust has the largest effect on perceived community-brand similarity as well as on self-image congruity. Hence, cognitive-based trust is far a more important factor than affect-based trust for the effects on psychological factors. Self-image congruity has significant and positive effects on the intention to give, obtain, and pass information. Self-image congruity has the largest effect on the intention to pass information as well as on the intention to obtain information, but sense of belonging has the largest effect on the intention to give information. The effects of perceived community-brand similarity on the intention to give information and the intention to obtain information are significant yet mild.

Practical implications

SNS members are eager to participate in e-word-of-mouth (e-WOM) activities via affection and social interaction, care for each other, and a feeling of concern. SNS managers should focus on members’ interaction content and processes to foster long-term relationships and create value propositions. Managers should use innovative online platforms to maintain communication and interaction in order to: provide cognitive trust among members; acquire members’ trust; retain members; and enhance members’ connectivity. SNS managers must increase members’ psychological connection, utilize cognitive-/affect-based trust, and attract brand devotion for common interests.

Social implications

In terms of the SNS members’ interaction and participation in interpersonal relationships, psychological perspectives can generate long-term reliance and sense of belonging. The willingness to exchange information and the involvement of continuous participation can affect the e-WOM behavior of giving and passing information. Brand fan page members are more willing to engage in e-WOM intentions when they have a higher self-image congruity and sense of belonging.

Originality/value

This study adopts the tricomponent attitude model to examine the relationship among cognition, affection, and behavioral intentions of community members between individuals and groups.

Abstract

Purpose

The purpose of this paper is to develop a conceptual framework to describe the continual usage of social computing systems from an experiential perspective.

Design/methodology/approach

A conceptual framework is developed using theories formulated from a variety of disciplines including information system (IS) continuance, relationship formation, human-computer interaction, and motivation theory.

Findings

The conceptual framework encompasses the relationship and experiential perspective of user-computer interactions. The framework also identifies factors that contribute to the continual usage of social computing by users and how these factors are related with system features.

Research limitations/implications

This study does not include an empirical analysis to validate the conceptual framework proposed in this study. Future research is encouraged to examine the ten propositions from the proposed conceptual framework.

Practical implications

The conceptual framework takes a different approach which is well suited for examining the continual usage of social computing applications (SCAs).

Originality/value

Previous research investigating factors that contribute to the continual usage of social computing often examined using static and utilitarian-based models. The conceptual framework in this study provides a different perspective for explaining why people use SCAs.
