With the rapid development of paid online social question and answer (Q&A) communities, monetary social functions have been introduced and have potential benefits for both platforms and users. However, these functions' impact on knowledge contribution remains uncertain. This study proposes a conceptual model based on the stimulus–organism–response framework, according to which monetary and non-monetary social functions can help nurture short-term and long-term relationships among community users, and thereafter improves social identity and knowledge-sharing intentions.

This study selects Zhihu, a famous online social Q&A community in China, and conducts an online survey to collect data from its frequent users. A sample of 286 valid questionnaires was collected to test our research model by using a structural equation modeling method. In addition, a bootstrapping approach is used to test the mediation effect.

Results indicate that monetary social functions help nurture short-term and long-term relationships among community users. However, non-monetary social functions only affect short-term relationships directly. Short-term and long-term relationships both have a positive relationship with social identity and thereafter improve users' knowledge-sharing intentions.

This study focuses on users' knowledge-sharing intentions in Q&A communities from the perspective of social. Specifically, we separated social functions in Q&A platforms into monetary and non-monetary ones and explored their impact on the development of short-term and long-term relationships. Results demonstrate the importance of monetary social functions and explain how monetary and non-monetary social functions affect users' knowledge-sharing intentions in different approaches.

The purpose of this paper is to explore the impact of mobile social media functions on explicit and implicit knowledge sharing under the “Guanxi” system based on the framework of stimulus–organism–response (SOR).

Combined with Guanxi theory, this paper designs an experiment to collect data from the new product development (NPD) teams.

Interestingly, the results show that the effect of social media communication function on employees is greater than the impact of collaboration on employees. Specifically, on the one hand, the more employees communicate in social media, the better their feelings will be, the less they will share knowledge. On the other hand, the collaboration function has a significantly negative impact on the psychological factors of employees. Excessively close cooperation and contact may instead create a contradiction between the employees, which is not conducive to the occurrence of knowledge sharing.

This paper extends SOR framework by combining Guanxi theory to examine the relationship between social media functions and knowledge sharing behavior (KSB). In practical, companies should pay attention to the frequency of employee using social media when it is introduced for NPD teams to control the negative influence of social media functions on employee KSB.

This paper aims to explore when and why consumers hold inconsistent and consistent choices between self- and gift-purchases.

Across three paper-based questionnaire experiments, the authors examine how consumers’ preferences for desirability and feasibility vary with purchase types (self- vs gift-purchases) based on the functional theories of attitudes. The authors examine consumers’ attitude functions and their self-monitoring closely associated with chronic attitude functions.

The findings show that the social adjustive function moderates whether consumers hold consistent or inconsistent preferences across the two purchases. Specifically, consumers generally rely more on desirability in gift-purchases than self-purchases, whereas this inconsistent preference only exists when the social adjustive function is comparable or advantaged to the utilitarian function. When the social adjustive function is significantly disadvantaged relative to the utilitarian function, consumers consistently prefer feasibility irrespective of self- or gift-purchases.

The research contributes to the familiar topic of consumers’ choice trade-offs between self- and gift-purchases. It documents the moderating role of the social adjustive function of consumers’ attitudes in whether they hold consistent or inconsistent choices across the two purchases. This extends the extensive research on self-other decisions.

The findings strongly suggest retailers identify or manipulate consumers’ attitude functions to make the attitude functions align with the purchase type when recommending products.

Most relevant literature focuses on exploring choice differences between self- and gift-purchases. This research not only explores the choice differences but also attempts to find the condition under which people’s choices do not differ between the two purchases.

Older people have a different perception of ageing and different factors can influence this perception. Among the factors influencing the perception of ageing are various functions including physical, mental and social functioning of the elderly. Therefore, in this study, the authors intend to investigate the relationship between the perception of ageing and social functioning.

A systematic search was conducted of four electronic databases (PubMed, Embase, Web of Science and Scopus). Citations within identified reports were also searched. Studies were included if they included perceptions of ageing and social functioning measures involving older participants. Study selection and data extraction were conducted using predefined criteria. Older adults’ perceptions of ageing and social functioning were assessed with a variety of measures.

From a total of 79 articles, eight reports met the criteria for inclusion. In these studies, the positive and negative aspects of ageing perception and various social functions of the elderly in society such as economic, political, social activities; social support; and formal and informal participation have been raised.

The results of this narrative review demonstrate that there is a two-way relationship between the perception of ageing and social functioning. Therefore, it is suggested that appropriate practical and educational interventions be taken to increase the positive perception of ageing in the elderly and increase the social performance of the elderly in society.

In the era of digital evolution, companies are increasingly deploying digital platforms to optimize operational efficiencies and to connect with customers more directly. However, little is known about whether and how companies can leverage digital platforms to enhance their brand prestige. Integrating insights from the resource-based view of the firm into the branding literature, this study aims to compare and distinguish the effects of the two digital platform functions, technical and social functions, on a company’s brand prestige. This study also assesses the moderating roles of two institutional factors, market uncertainty and brand imitation.

This study estimates a moderated regression model using a survey of 240 companies in China that deploy digital platforms. This study uses SPSS 24.0 to perform regression analysis.

The study finds that technical functions positively, whereas social functions negatively affect brand prestige. Moreover, the technical functions of digital platforms are more beneficial for companies to build their brand prestige when the market is turbulent and the extent of brand imitation is high, whereas, under the same conditions, social functions lead to lower brand prestige.

There are several limitations of this study that offer future research opportunities. First, due to the difficulties of data collection, measures were taken from the same source for which common method bias could be a potential concern. Second, this study considered two institutional boundary conditions in these models. Future research should consider mediators as well as other potential moderators to understand the underlying mechanisms of how digital platforms affect brand prestige. Third, future studies may develop better constructs to manifest these two types of digital platform functions. Finally, this sample was limited to companies in China.

This study provides important implications for companies leveraging digital platforms to build brands. First, companies must distinguish between the different functions of digital platforms. The findings reveal that companies that leverage digital platforms to build brand prestige are suggested to make greater use of technical functions yet should be cautious in developing social functions. Second, this research suggests although market uncertainty and brand imitation are not conducive to enhancing brand prestige, it is possible for companies to take advantage of these unfavorable environments to better serve niche customers.

Prior marketing studies emphasize the benefits of digital platforms and largely overlook the double-edged sword effect of digital platforms on companies’ brand building. This study contributes to the marketing literature by revealing the benefits of technical function and the challenges of social function in driving brand prestige in complex institutional settings.

If everyone were indifferent between more and less and between this and that, the problems of allocating scarce resources would be trivialized. The necessity of choice, whether social or individual, would seem absurd. However, people persist in preferring certain “states of the world” to others. As a society is made up of individuals, it seems reasonable that a society's preferences should be “made up” of the preferences of its members. Therefore, any social welfare function, W, should be a function of the individual welfare functions, wi. That is,

Despite the recent increase in vegetarian food consumption, studies on this topic have focused on the product category. Based on the functional theory of attitude and the cognitive–affective–conative framework, this study investigates the impact of customer individuality (i.e. uniqueness and level of self-monitoring) on cognitive attitude (i.e. social-function attitudes), which leads to conative attitude (i.e. behavioral intentions) via affective attitudes toward vegetarian restaurants.

The sample (n = 176) comprises experienced vegetarian restaurant customers in the USA. Multi-group analysis is used to examine differences between vegetarian and non-vegetarian customers, as well as customers' low and high frequency in visiting vegetarian restaurants.

Using partial least squares structural equation modeling, this study finds the relative impact of customers' personal traits on self-expressive and social-adjustive functions. Results highlight the role of the social-adjustive function as an antecedent of affective attitudes leading to positive behavioral intentions. Last, the findings from a multi-group analysis show that customer self-monitoring is the only significant antecedent of a cognitive attitude among vegetarian customers.

The present study adds to the literature regarding trait attributes and corresponding cognitive, affective and conative attitudes in the context of the vegetarian food service industry.

A humanoid intelligent robot (HIR) possessing a human-like appearance can undertake human jobs, interact, communicate and even transmit emotions to human beings. Such robots have gradually been integrated into people's daily life and production scenarios. However, it is unclear whether and by what mechanism HIRs can stimulate people’s risk perception and its impact on consumption attitudes. Based on the risk decision theory, this study aims to take the social value substitution attribute of a HIR as the incentive and analyzes the influence of social value substitution and risk perception on the customers’ consumption attitudes.

Three experiments were conducted to investigate the related questions about the social value substitution attribute of a HIR, its impact on risk perception and the customers’ consumption attitudes.

The results reveal that physical labor, intellectual labor, friendship, kinship and the ego constitute the hierarchical elements of social value substitution. Among them, physical labor and intellectual labor pertain to the dimension of social function value substitution, while friendship, kinship and ego pertain to the dimension of social presence value substitution; social function value substitution and social presence value substitution affect the subjects’ risk perception positively, but the latter arouses a stronger risk perception; the 2 (risk perception of social function value: security/danger) × 2 (risk perception of social presence value: security/danger) condition corresponds to diverse consumption attitudes.

The results enrich the theories of the “cha-xu pattern” and “uncanny valley” and provide reference for the healthy development of the HIR industry.
