Abstract

Purpose

The biomaterials are natural or synthetic materials used to improve quality of life either by replacing tissue/organ or assisting their function in medical field. The purpose of the study is to analyze the hydroxyapatite (HAP), HAP-TiO2 (25 percent) composite coatings deposited on 316 LSS by High Velocity Flame Spray (HVFS) technique.

Design/methodology/approach

The coatings exhibit almost uniform and dense microstructure with porosity (HAP = 0.153 and HAP-TiO2 composite = 0.138). Electrochemical corrosion testing was done on the uncoated and coated specimens in Ringer solution (SBF). As-sprayed coatings were characterized by XRD, SEM/EDS and cross-sectional X-ray mapping techniques before and after dipping in Ringer solution. Microhardness of composite coating (568.8 MPa) was found to be higher than HAP coating (353 MPa).

Findings

During investigations, it was observed that the corrosion resistance of steel was found to have increased after the deposition of HAP and HAP-TiO2 composite coatings. Thus, coatings serve as an effective diffusion barrier to prohibit the diffusion of ions from the SBF into the substrate. Composite coatings have been found to be more corrosion resistant as compared to HAP coating in the simulated body fluid.

Research limitations/implications

It has been concluded that corrosion resistance of HAP as well as composite coating is because of the desirable microstructural changes such as low porosity high microhardness and flat splat structures in coatings as compared to bare specimen.

Practical implications

This study is useful in the selection of biomedical implants.

Social implications

This study is useful in the field of biomaterials.

Originality/value

No reported literature on corrosion behavior of HAP+ 25%- TiO2 has been noted till now using flame spray technique. The main focus of the study is to investigate the HAP as well as composite coatings for biomedical applications.

Abstract

Purpose

This study aims to examine the antecedents of purchase intention toward energy efficient air conditioners by incorporating the theory of planned behavior (TPB) with two additional constructs, i.e. environmental concern and personal norms. TPB is one of the most widely used theoretical framework to study consumer behavior.

Design/methodology/approach

The study applied a quantitative technique using a survey method by distributing self-administered questionnaires among the Indian households who have purchased energy efficient air conditioners in the past six months or had enquired to do so. The study collected data from three select regions: Delhi and NCR, Punjab and Tri-city. The collected data of 424 respondents have been analyzed using confirmatory factor analysis and structural equation modeling.

Findings

The study posits that normative factors such as subjective norms and personal norms have a relatively higher influence on purchase intention. Despite the significant existence of environmental concern, the study did not find environmental concern directly influencing purchase intention.

Research limitations/implications

The sample size of the study is too small and pertains to specific regions. Thus, it could hinder the generalizability of the results. Advertisement appeals should be related with enhancement of self-esteem in terms of making responsible and valuable contribution to environment protection through the purchase of energy efficient air conditioner.

Originality/value

There are a few studies in the Indian context studying consumer’s purchase intention toward energy efficient air conditioners to which this study adds. The study provides an important contribution to marketers in developing strategies for increasing purchase intention toward energy efficient air conditioners in view of their stage in the product life cycle, diffusion of product and influence of normative factors.

Abstract

Purpose

This paper examines actors and discourses shaping new Canadian legislation designed to advance diversity in corporate governance.

Design/methodology/approach

This paper performs a stakeholder and discourse analysis drawing on texts of parliamentary debates.

Findings

The paper illuminates tensions regarding definitions of diversity, its importance for boards of directors and the mechanisms favoured for implementation. Official discourses examined show that, unlike for other political issues, opposition was largely muted, and most stakeholders engaged in the process supported legislation advancing diversity. Nonetheless areas of debate and positioning by actors and suggest important differences, with outcomes linked to non-traditional power bases.

Research limitations/implications

This study provides insights into the discursive environments of organizations and processes relating to promoting diversity and equality in the political decision-making domain, a critical venue for understanding advancement of equity, often neglected in organizational studies.

Practical implications

By understanding the complex and competing discourses surrounding diversity and inclusion at the macro level this paper provides a context for understanding organizational (meso) and individual (micro) beliefs and behaviours.

Social implications

This study shows how advocacy shapes how policy and legislation are framed and the ways mainstream organizations, including women's groups, may advance gender equality without regard to other dimensions of diversity or intersectionality.

Originality/value

This study maps the political discourse around recent Canadian legislation designed to improve diversity on boards that must, in the Canadian context, address more than gender.

Abstract

Purpose

This study aims to build a comprehensive model for developing higher education institutes (HEIs) brand equity by examining the impact of HEIs intangible resources, brand management aspects, attachment strength and student’s contemporary citizenship behavior (CCB).

Design/methodology/approach

Data were gathered through a self-administered questionnaire from Indian students and alumni (n = 703). The study examines the proposed comprehensive model through serial and multiple mediation analysis.

Findings

The study unfolded “service quality? brand image? attachment strength? word-of-mouth? brand equity” as the most significant path to develop HEI’s brand equity.

Research limitations/implications

This study pioneers an empirically validated mechanism for developing brand equity in HEIs, addressing gaps identified by previous studies and offering a theoretical framework that elucidates how HEIs can leverage intangible resources through strategic brand management to foster attachment and influence positive student behaviors, thereby contributing to the development of HEI brand equity.

Practical implications

HEIs need to understand that relying solely on tangible aspects leads to short-lived effects. To maintain a lasting competitive advantage, HEIs should focus on crafting a rich historical narrative, retaining talented faculty and staff and earning respect from the public to build a lasting reputation.

Originality/value

This study develops the mechanism for developing brand equity of HEIs using its valuable, rare and inimitable intangible resources. Along with the introduction of novel constructs like competence, heritage and word-of-mouth to existing study, the proposed conceptual model is premised on the theory of self-congruence, social-exchange theory and CCB.

Abstract

Purpose

The purpose of this paper is to explore the key performance indicators (PIs) that serve as a decision support tool in case of dairy supply chain practices and to analyze their interactions in the context of Indian dairy industry sector. A total of 11 PIs have been identified through the literature review and the opinions of an expert team consisting of managerial and technical experts from dairy industry and academics.

Design/methodology/approach

A solution methodology based on the interpretive structure modeling (ISM) technique is used to analyze the interactions among PIs and to propose a structural model. The developed model not only helps in understanding the contextual relationship among the PIs, but also in determining their interdependence to assess the supply chain performance in dairy industry. Further, the importance of PIs has been determined based on their driving and dependence power by using MICMAC analysis.

Findings

The ISM-based model suggests four PIs at first level, three PIs at second level, one PI at third level as well as one PI at fourth level and two PIs at fifth level. Model allocates to the effective information technology, brand management, responsiveness in shipment and accuracy and a control over wastages as the key PIs in the dairy industry sector. The effective traceability systems, cold chain infrastructure, quality management and the support for technological innovations are the next major PIs. There exists no autonomous PI in MICMAC analysis which proves the importance of identified PIs in the case study.

Research limitations/implications

The proposed model is an attempt to capture the dynamics of milk processing sector and to incorporate all relevant constraints related to internal and external environments that would significantly improve the supply chain performance in the dairy industry.

Practical implications

The model developed in this study has been tested in the cooperative milk processing units based in India and also discussed with the experts from academics. This work may help practitioners, regulators and dairy industry professionals to focus their efforts toward achieving high performance by the effective implementation of the identified PIs.

Originality/value

In this study, 11 PIs are considered. Interactions among PIs are evaluated with the help of the ISM matrix. Out of the 11 PIs, six demonstrate both strong driving and dependence power as explained in the MICMAC analysis.
