Knowledge-sharing (KS) for preventing identity theft has become a major challenge for organisations. The purpose of this paper is to fill a gap in the literature by investigating barriers to effective KS in preventing identity theft in online retail organisations.

A framework was proposed based on a reconceptualisation and extension of the KS enablers framework (Chong et al., 2011). A qualitative case study research method was used for the data collection. In total, 34 semi-structured interviews were conducted in three online retail organisations in the UK.

The findings suggest that the major barriers to effective KS for preventing identify theft in online retail organisations are: lack of leadership support; lack of employee willingness to share knowledge; lack of employee awareness of KS; inadequate learning opportunities; lack of trust in colleagues; insufficient information-sourcing opportunities and information and communications technology infrastructure; a weak KS culture; lack of feedback on performance; and lack of job rotation.

The research provides solutions for removing existing barriers to KS in preventing identity theft. This is important to reduce the number of cases of identity theft in the UK.

This research extends knowledge of KS in a new context: preventing identity theft in online retail organisations. The proposed framework extends the KS enablers framework by identifying major barriers to KS in the context of preventing identity theft.

This paper aims to propose a framework for the dimensions of frugal innovation enablers in small and medium-sized enterprises (SMEs).

A mixed research approach has been applied. First, by a comprehensive literature review, the most important factors influencing frugal innovation have been identified. Then, an interview has been conducted with 18 experts who were selected by snowball sampling method. In the next step, all identified variables have been modified in a questionnaire with 48 factors, which were distributed to 200 employees and managers of SMEs in the home appliance manufacturing industry of Isfahan province, who were selected by non-random sampling. Data has been analyzed using SPSS-25 software for exploratory factor analysis.

Findings indicated that the most important enablers of frugal innovation are world-class design, human aspect, marketing, support, knowledge, social aspect, prototyping, cultural aspect, environmental aspect, distinct brand creation, core functions focus, local R&D, cost-cutting business model and low-cost production.

The proposed framework provides an effective basis to managers and decision-makers in the field of frugal innovation to evaluate their capabilities in implementing frugal innovation, the results of which are helpful in developing a roadmap for achieving frugal innovation in SMEs and particularly in home appliance manufacturing companies.

The comprehensive framework of this study has not been applied, developed or studied in the literature. The proposed framework provides new insights for future studies on the subject of frugal innovation, e.g. investigating the influence of frugal innovation on frugal innovation performance.

The purpose of this paper is to investigate the effect of TiO₂ nanoparticle content on the corrosion behavior of Ni‐Cr/TiO₂ nanocomposite coatings applied by pulse‐reverse electroplating.

Ni‐Cr/TiO₂ nanocomposite coatings with various contents of TiO₂ nanoparticles were electrodeposited by pulse‐reverse method from a bath containing TiO₂ nanoparticles to be codeposited and citric acid as the complexing agent. The surface morphology and the composition of coatings were studied by scanning electron microscopy (SEM) equipped by energy dispersive X‐ray system (EDS). The corrosion performance of coatings in the 0.5 M NaCl as a corrosive solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods.

It was found that the surface of Ni‐Cr/TiO₂ nanocomposite coatings showed a finer structure that was more uniform and compact in appearance than was that of Ni‐Cr coatings. The incorporation of TiO₂ nanoparticles in the alloy coating matrix improved the corrosion performance of the coatings and the higher content of nanoparticles gave better corrosion resistance.

Applying the Ni‐Cr coatings by the pulse‐reverse plating method eliminated cracks that were a problem in the Ni‐Cr alloy coating structure. Furthermore, the corrosion resistance was improved by the addition of TiO₂ nanoparticles to the alloy matrix. This paper reports the optimum plating conditions that gave the better corrosion performance.
