Abstract
Purpose
The purpose of this paper is to study the recent work carried out in enhancing the properties of bitumen using nano-additives. Bitumen is a by-product obtained from the refining process of crude oil, therefore making it a diminishing product. It has been used by mankind since ages for various applications like sealants, binders, waterproof coatings and pavement construction material. It is a black viscous substance with adhesive nature.
Design/methodology/approach
Bitumen is used as a binding material because of its ability to become liquid when heated and become solid when cooled and thus used largely in construction of roads because of its unique properties. Low softening point of bitumen leads to melting of bitumen during summer and causes rutting of roads, whereas during winter it leads to cracking as bitumen acts brittle in nature during low temperature. Increasing global demand of bitumen has created gap between demand and supply which is increasing with the passage of time. Further modern life has created very high traffic volume and heavy load which makes it essential to improve performance of bitumen.
Findings
Research studies have reported that the thermal properties of bitumen are enhanced by using thermoplastic polymers such as styrene-butadiene-styrene, polyethylene and ethylene-vinyl acetate, rubber and bio waste etc.
Originality/value
This paper reviews various types of materials which have been used to improve the properties of bitumen and explores the possibility to synthesise bitumen composite materials with nanoadditives with improved structural, mechanical and thermal properties.

Abstract
The present paper is an attempt to explore the emerging stem cell innovation system in India. It is contended that the social capital in terms of linkages of various sorts can no longer be ignored to strengthen the innovation system and that the coevolution of technology and institutions is yet to emerge. It seems that given the nature of complex technologies involved, there is a greater need felt for R&D and training collaboration and hence linkages of various types are taking place. For shaping futures for a balanced growth of this sector, the institutions in India will have to be geared towards greater coordination, promotion of greater knowledge flows at national as well international levels. This paper also analyses the strengths and barriers in the development of rapidly growing stem cell research in India along with future challenges.

Abstract
Purpose
This paper aims to examine the influence of leaves of Cucurbita maxima (LCM) extract on the corrosion of mild steel (MS) in 1N H2SO4 by gravimetric measurement and electrochemical study. The inhibition efficiency increased with increase in concentration of LCM. The corrosion rate increased with increase in temperature and decreased with increase in concentration of inhibitor compared to blank. The maximum inhibition efficiency of 96 per cent was obtained at 3 per cent v/v LCM at 343K for 1 h. The inhibitory action was explained on the basis of adsorption of secondary metabolites in the plant extract on the mild steel surface. The adsorption process obeys Langmuir, El-Awady, Temkin and Freundlich adsorption isotherms and was best fitted by Langmuir adsorption isotherm. Some kinetic and thermodynamic parameters are also discussed.
Design/methodology/approach
Weight loss measurements were conducted under total immersion of already weighed mild steel coupons in 100 ml of the test solution containing 0.05, 0.5, 1, 1.5, 2, 2.5 and 3 per cent of LCM extract and in blank solution at different temperature range (303, 313, 323, 333 and 343 K) for 1h. The electrochemical experiments were conducted at room temperature and at various concentrations of LCM extract. The electrochemical experiments were performed using a potentiostat. A three-electrode cell was used for the impedance measurements conducted at open circuit potential.
Findings
The inhibitor (LCM) shows good inhibition performance for the corrosion of mild steel in 1N H2SO4 solution. The inhibition efficiency increased and the corrosion rate decreased with increasing concentrations of inhibitor.
Originality/value
The studied plant material is a new one in mild steel corrosion. The influence of the plant material is clearly explained in the submitted paper.

Abstract
Brand equity has been highlighted as a crucial element in differentiating products and achieving competitive advantage. Recent studies reflect the gradual rise in interest in the importance of building brand equity linked to the store. However, empirical evidence about the antecedents of store brand equity is still scarce, particularly on the retailer’s corporate social responsibility behavior. This chapter aims to analyze the influence of the retailer’s commitment to sustainable development (RCSD) and the credibility of the retailer’s communications on the overall store brand equity. Focusing on two samples of hypermarket customers in France and Spain, the findings provide evidence on the importance of the RCSD regarding employees, society, and environment, as well as the effectiveness of credible communications to generate store brand equity. Results are consistent for France and Spain.

Abstract
Purpose
United Nations’ World Population Ageing Report states that falls are one of the most common problems in the elderly around the world. Falls are a leading cause of morbidity and mortality among mature adults, and the second leading cause of accidental or unintentional injury/death after road traffic injuries. The rates are higher in hospitalized patients and nursing home residents. Major contributing reasons for falling are loss of footing or traction, balance problem in carpets and rugs, reduced muscle strength, poor vision, mobility/gait, cognitive impairment: in other words lack of balance. Balance can be improved by the practice of yoga which helps to balance both body and mind through a series of physical postures called asanas, breathing control and meditation. Elders, especially women, are often unable to practice yoga regularly, largely brought on by a feeling of discomfort at having to do so in full public view, preferring instead to have private sessions at home, and at leisure. A computer-assisted self-learning system can be developed to help such elders, though improper training and the postures associated with it may harm the body’s muscles and ligaments. To have a flawless system it is essential to classify asanas, and identify the one the practitioner is currently practicing, following which the system can offer the guidance necessary. The purpose of this paper is to propose a posture recognition system, especially of sitting and standing postures. Asanas are chiefly classified into two: sitting and standing postures. This study helps to decide the values of the parameters for classification, which involve the hip and joint angles.
Design/methodology/approach
To model human bodies, skeleton parts such as head, neck (which are responsible for head movements), arms, hands (to decide on hand postures), and legs and feet (for standing posture identification) have been modeled and stored as a vector. Each feature is defined as a set of movable joints. Every interaction among the skeleton joints defines an action. Human skeletal information may be represented as a hierarchy of joints, in a parent–child relationship. So that whenever there is a change in joint its corresponding parent joint may also be altered.
Findings
The findings have to do with analyzing the reasons for falls in the elderly and their need for yoga as a precautionary measure. As yoga is ideally suited to self-assisted learning, it is feasible to design a system that assists people who do not wish to practice yoga in public. However, asanas are to be classified prior to doing so. In this paper, the authors have designed a posture identification framework comprising the sitting and standing postures that are fundamental to all yoga asanas, using joint angle measurements. Having fixed joint angle values is not possible, given the variations in angle values among the participants. Consequently, such parameters as the hip joint and knee angles are to be specified in range for a classification of asanas.
Research limitations/implications
This work identifies the angle limits of standing and sitting postures so as to design a self-assisting system for yoga. Yoga asanas are classified and tested to enable their accurate identification. Extensive testing with older people is needed to assess the system.
Practical implications
The increase in the population of the elderly, coupled with their need for medical care, is a major concern worldwide. As older people are reluctant to practice yoga in public, it is anticipated that the proposed system will motivate them to do so at their convenience, and in the seclusion of their homes.
Social implications
As older people are reluctant to adapt as well as practice yoga in public view, the proposal motivates and helps them to carry out yoga practices at their convenience.
Originality/value
This paper fulfills the initial study on the need and feasibility of creating a self-assisted yoga learning system. To identify postures and classify them joint angles are used; their range of motion has been calculated in order to set them as parameters of classification.

Abstract
Purpose
The purpose of this paper is to examine the barriers to knowledge management (KM) due to various national cultural dimensions and to understand how social media can be used to mitigate those barriers to KM processes within organizations.
Design/methodology/approach
The paper begins with a focussed review of existing literature to understand the key concepts in KM and national culture. The paper then outlined the important dimensions of national culture and the barriers they introduce to the KM processes. The paper also briefly reviews the features of some of the popular social media tools available. The paper then conceptually link the three areas of KM, national culture and social media to emerge with a clear picture of how social media can overcome KM barriers due to specific cultural traits.
Findings
National culture has multiple dimensions and each of these dimensions can act as a significant barrier to KM within organizations. Social media tools have rich interactive features which can help overcome these barriers. Choosing the correct social media tool with specific features can help alleviate the issues introduced by specific cultural traits.
Originality/value
This paper integrates the three areas of KM, national culture and social media. It provides an understanding of how the various cultural dimensions can act as barriers to KM. It particularly outlines specific social media tools to remedy obstacles to KM due to each of the national culture dimension.

Abstract
In this chapter, the author critically examines the deeply entrenched practices and theories within counselor education, revealing their roots in historically dominant, Eurocentric, and often racially oppressive assumptions. This study brings to light the pervasive impact of these traditional approaches, illuminating their role in perpetuating racial oppression and disparities in mental health care. The author presents a compelling argument for adopting Critical Race Theory (CRT) as an effective pedagogical and clinical practice framework in the counseling profession, a step toward its much-needed liberation. CRT's tenets are examined as a robust alternative, promoting socially just outcomes in counseling and psychotherapy. The article highlights CRT's capacity to address the well-established relationship between racism, white supremacy, and minority mental health. It proposes a groundbreaking model for praxis, predicated on CRT, which holds potential not only to challenge and disrupt oppressive structures but also to pave the way for the liberation of both the oppressed and the oppressor. This seminal work prompts a re-envisioning of counselor education, asserting a call for a transformative shift toward a liberation-based, social justice pedagogy.

Abstract
Purpose
This study aims to explore consumers' perceptions of stealing thunder and to investigate significant factors for maximizing its effect.
Design/methodology/approach
This study used a mixed-methods approach. First, qualitative responses from 286 Korean participants were collected and analyzed (Study 1). Second, the experiment employed a randomized 2 (crisis communication timing: stealing thunder vs thunder) × 2 (transparent vs nontransparent communication) × 2 (follow-up actions: good vs poor) between-subjects experimental design with 426 Korean participants to investigate and confirm the results of Study 1.
Findings
Qualitative data showed that the participants' evaluation of corporations' stealing thunder strategy is complicated. Some do not perceive corporate use of stealing thunder at face value, but rather view it as yet another hopeless, selfish and irresponsible crisis communication strategy, distrusting it based on strong cynicism toward all corporations. An experiment confirmed that stealing thunder was significantly more effective in eliciting consumers' ethical judgment (EJ) and word-of-mouth (WOM) on corporations than the thunder strategy. Significant two-way interaction effects between crisis timing and follow-up actions showed that the stealing thunder strategy should be accompanied by follow-up actions to increase consumers' credibility and WOM intentions.
Originality/value
This study investigated how consumers evaluate stealing thunder by adopting both a qualitative and quantitative approach to explore how they make meaning out of this phenomenon.

Abstract
The emerging industrial revolution referred to as Industry 5.0 is focusing on leveraging human creativity with intelligent and autonomous systems to derive user-friendly work environment for the businesses. Industry 5.0 stresses on people centric work ecosystem, zero accident policy and the well-being of labour within the production processes. This approach of Industry 5.0 to obtain human-centric safety solutions through the deployment of digital technologies deduces workplace accidents and costs leading to the development of Safety 4.0. This chapter aims to investigate the opportunities and challenges of Safety 4.0 and its enabling technologies aspiring towards the greater impact on safety management. Further, we have proposed a framework for the role of human centric digital transformations concerning safety in the manufacturing industry propelling Safety 4.0. Concluding, we discuss the implications for managers and practitioners. We found that Safety 4.0 will strengthen industrial safety, and instead of reacting to accidents, the concept evolved towards a preventive and proactive approach for a healthy industrial ecosystem.
