Abstract

Purpose

This paper aims to investigate how brands’ social media activities (credible content delivery, co-creation and responsiveness) impact brand advocacy. The paper also examines the influence of brand advocacy on purchase intentions of brand advocates and the moderating effect of the amount of time spent on Facebook on the relationship between brand advocacy and purchase intentions. Finally, the moderating effect of brand type (goods vs services) on the relationship between brands’ activities and brand advocacy is explored.

Design/methodology/approach

US adults who use Facebook as their primary social media platform participated in a survey via Amazon Mechanical Turk. Structural equation modeling was used to test the proposed hypotheses.

Findings

The three brand activities are positively related to users’ advocacy of brands toward other users. Brand advocacy also positively influences purchase intentions of brand advocates. The amount of time spent on Facebook moderates the relationship between brand advocacy and purchase intentions. The brand type moderates the relationship between co-creation and brand advocacy.

Originality/value

This study differs from the existing research, which has typically used a user-oriented perspective (e.g. impact of user motivations) to explain brand advocacy and has not considered the outcome of brand advocacy on the brand advocates’ purchase intentions.

Abstract

Purpose

Drawing upon the knowledge sharing model, the purpose of this paper is to identify personal and environmental antecedents to information sharing on social networking sites (SNSs) and examines the interaction effects between the two factors.

Design/methodology/approach

Data were collected via online survey with college students. Hierarchical multiple regressions were performed to test hypotheses and examine research questions.

Findings

With regard to environmental factors, the more users perceive their audience to be a collection of weak ties, the more likely they are to share information on SNSs, independent of the size of their networks. Personal factors such as information self-efficacy, positive social outcome expectations, and sharing enjoyment feelings were found to be significant predictors of sharing activities. In addition, a significant interaction effect was found such that the effects of social outcome expectations on sharing activities on SNSs are manifested to a greater extent when users perceive their audience as weak ties rather than strong ties.

Originality/value

This study extends the knowledge sharing model literature by applying it to the SNS context and advances SNS research by taking into consideration both environmental factors and personal factors and their interactions.

Abstract

Purpose

Construction is an information and knowledge driven industry. Construction firms all over the world are increasingly being challenged by high‐cost pressure, shortened project cycles and increasing competition. Within a business environment, where fast and reliable access to knowledge is a key success factor, the efficient handling of organisational knowledge is crucial. The purpose of this paper is to look at ways knowledge and expertise are managed in project‐based firms, based on three case studies. The knowledge management (KM) effort established in these cases studies is analysed. Finally, the findings from the case studies from the perspective of the construction firm are presented.

Design/methodology/approach

The research methodology of the study is that of interpretative case study and grounded theory based on a strong empirical foundation, on which new theoretical insight into KM as an autonomous action is developed. Case study research is one of the most widely‐used research designs in qualitative research. The grounded theory method develops theory from data collected through direct contact with research situations. The methodology looks at large, successful companies already using KM, which not typical companies, but which provide useful insights for others.

Findings

This paper analyses KM effort, based on three case studies and offers recommendations and insights for enhancing KM in construction firms.

Research limitations/implications

Construction firms need to be aware of the advantages of KM initiatives and practices. KM requires an environment that allows workers to create, capture, share, and leverage knowledge to improve performance. Firms are increasingly utilizing interdisciplinary organisational structures in which employees share knowledge and expertise within and between groups in order to cope with complex tasks.

Originality/value

This paper presents the findings from case studies of three large, high‐performing project‐based firms, involving exploratory, open‐ended interviews with managers at various levels, and identifies key KM implementation issues in construction firms; it also provides valuable insights and recommendations for enhancing the capture, sharing and use of corporate knowledge assets.

Abstract

Purpose

This study aims to investigate the fabrication of hydrogen gas sensor based on metal–oxide–semiconductor (MOS) microstructure. The palladium nanoparticles (PdNPs) as gate metal have been deposited on the oxide film using spin coating.

Design/methodology/approach

The PdNPs and the surface of oxide film were analyzed using Transmission electron microscopy. The capacitance-voltage (C-V) curves for the MOS sensor in 1, 2 and 4 per cent hydrogen concentration and in 100 KHz frequency at the room temperature were reported.

Findings

The response times for 1, 2 and 4 per cent hydrogen concentration were 2.5 s, 1.5 s and 1 s, respectively. The responses (R per cent) of MOS sensor to 1, 2 and 4 per cent hydrogen concentration were 42.8, 47.3 and 52.6 per cent, respectively.

Originality/value

The experimental results demonstrate that the MOS hydrogen gas sensor based on the PdNPs gate, shows the fast response and recovery compared to other hydrogen gas sensors based on the Pd.
