This paper aims to combine Mäkipää et al., Füller et al., and Ahonen et al. with regard to CBI ideas, and applies them to the new product development process of the firm. The main research links user innovation and commercialization, and the discussion between the members creates centripetal and condensation strengthening factors. A complete model is developed for empirical testing.

The sample is 143 participants from five online communities of firms operating in Taiwan, namely Microsoft, Working House, Inventec Corporation, Hometec Technology Inc., and Asustek Computer Inc., that were contacted and asked to participate in the study. Data were collected from March 19 to May 31, 2008 via the web for internet users using a standardized questionnaire. Excluding those surveys that were undeliverable and those who believed that it was inappropriate to respond, the overall effective response rate was 87 percent (125 of 143).

This research proposes four other factors to promote the member participation CBI degree effectively, and further affects them to participate in the company's desire for three stages of new product development. But studies regarding the participation product concepts and design stage also find the members comparatively are not interested. Finally, a complete model is developed for empirical testing. It seems to be a promising source of innovation capabilities for new product development.

The focus in this study is on how the integration of community members into new product development using the community based innovation method leads to encouraging results. Nevertheless, it is difficult to claim its general usability. So far, there is no study indicating the effectiveness and efficiency of CBI for ongoing, continued consumer integration. Then studies concerning the impact of CBI on innovation success are just beginning, and are restricted to the initial findings of a few case studies. Therefore, the actual market impacts of co‐developed products has not been tested on a large scale, as most of the CBI projects have not been carried to the point of testing the innovations in an actual marketplace.

The main contribution of the CBI method lies in the systematic utilization of the existing, but so far merely exploited, innovative potential of online communities. However, none of the previous studies have integrated these variables into a more comprehensive framework. A complete model is developed for empirical testing. And the discussion between the members creates centripetal and condensation strengthening factors. The main research links user innovation and commercialization.

Population aging was a global trend, and the most obvious thing after aging was the change in skin appearance. Therefore, the active ingredients that delay skin aging were particularly noticed. Past studies had pointed out that Chinese herbal extracts can improve skin elasticity, reduce wrinkles and melanin precipitation. The purpose of this paper is to explore whether combining hydrolyzed collagen with Chinese herbal extracts can improve skin conditions and achieve anti-inflammatory effects.

Fifty subjects were randomly divided into collagen or placebo groups, and one bottle of collagen or placebo drink was used every day for four weeks, after which skin and inflammatory factors were tested.

In comparison with the baseline results, the skin parameters were improving after four-week intervention. In addition, the IL-6, IL-8, TNF-a were significantly decreased and tissue inhibitor matrix metalloproteinase 1 (TIMP-1) was increased after four-week hydrolyzed collagen intervention.

This study showed that hydrolyzed collagen combined with Chinese herbal extracts can improve the condition of the skin, and can also reduce inflammatory associated factors, thereby achieving anti-aging effects.

The purpose of this paper is to attempt to unlock how and why abusive supervision influences employees’ day-to-day behaviors. Thus, the present study proposes that employees who are continuously faced with a supervisor’s hostile verbal and nonverbal behavior might obstruct their willingness to exhibit two different kinds of extra-role behaviors [i.e. organizational citizenship behavior (OCB) and voice] because sustained abusive behavior might hinder employees from their tasks and result in disengagement. Abused employees are more likely to disengage from their current tasks, and this is likely to in turn result in lower OCB and voice.

The data were collected from a Taiwan mid-sized high-tech manufacturing company. The present study adopted a within-person approach (a daily-basis research design) and collected data from 60 front-line employees over 10 working days. Although all variables were self-rated, common method variance is minor. Confirmatory factor analysis (CFA) was conducted to ensure discriminant and convergent validity, and hierarchical linear modeling (HLM) was used to test the hypotheses.

The results of CFA ensure the measures have discriminant and convergent validity, while the results of HLM analysis showed that work engagement fully mediates the negative relationship between abusive supervision and the two kinds of extra-role behaviors. The bootstrapping results also support the full mediation effect of work engagement.

The present study used the job demands-resources model to examine how abusive supervision influences employees’ OCB and voice and found that work engagement is one possible mechanism between these two types of extra-role behavior. Specifically, a daily research design discovered that in a given working day, once a leader exhibits abusive supervision behavior, compared with any given day without abusive behaviors, employees will find it difficult to focus on their current tasks (i.e. through exhibiting decreased work engagement), which will in turn influence their willingness to exhibit OCB and voice on that particular day. Thus, both researchers and managers should focus on the daily interactions between leaders and employees because it is impossible to achieve organization success in one day, but rather such success is the aggregate result of both leaders’ and employees’ daily efforts.

This study explores the impact of ethical and authentic leadership on employees' workplace perceptions, focusing on organisational citizenship behaviour (OCB), trust in leader, commitment, employee voice and empowerment in independent hotels across two contrasting Global Leadership and Organizational Behaviour Effectiveness (GLOBE) clusters: Germanic and Middle-Eastern clusters. It examines how national culture influences these relationships in the hospitality industry.

Data were collected from 1,678 employees in independent hotels in the Germanic European cluster (Germany and the Netherlands) and the Middle-Eastern cluster (Qatar and Turkey) using selective and snowball sampling techniques. Hypotheses were tested using two-stage structural equation modelling.

Ethical leadership significantly affects employee voice in Germany and the Netherlands but not in Qatar and Turkey. Authentic leadership positively influences employee voice in Qatar, Turkey and Germany but does not significantly impact trust in leader in any of the four countries. The study underscores the role of cultural dimensions, particularly power distance, in shaping these relationships.

This research contributes to the literature by investigating the effects of ethical and authentic leadership on key organisational variables in culturally diverse contexts within the hospitality industry. The findings highlight the necessity of considering national culture in leadership practices and suggest practical implications for independent hotels to adapt their leadership approaches to enhance employee outcomes. Future research should explore cultural dimensions as moderators in organisational relationships.

This study aims to contribute to literature on mobile learning (m-learning) by proposing four research clusters whereby scholars can expand m-learning research to facilitate effective learning experiences for students.

This study reviews student-centric literature on m-learning since 2010 and presents insights on m-learning while applying well-established bibliometric techniques. Consequently, 722 articles published in the past decade were evaluated by identifying key research areas, most influential authors, countries, journals and organisations. Most influential studies based on number of citations were also examined.

Through article co-citation analysis, four clusters representing m-learning literature were identified: concept of m-learning, application of m-learning in education, designing framework for model learning/acceptance and emerging technologies.

As mobile learning (m-learning) has undergone an evolution from being an emerging field to a significant teaching and research tool, it is pertinent to explore and identify the trends of m-learning research.
