Abstract
Introduction It is well established that Si in silicon bronzes imparts high strength and corrosion resistance which are essential requirements for applications in hydraulic pressure lines, heat exchangers, propeller shafts, storage tanks and other equipments for chemical industries. They have high corrosion resistance towards marine environments, but possess inferior corrosion resistance in sulphide bearing atmosphere although more resistant to stress corrosion cracking and season cracking than brass on exposure to polluted atmospheres. In general, corrosion resistance of alloys depends on alloy chemistry, heat treatment schedule, presence of second phase, precipitation morphology and specific environment. However, studies on influence of heat treatment and variation of silicon content in (Binary) Cu‐Si alloys with particular reference to their corrosion resistance in chloride and sulphide bearing environments are scanty in literature. The present work has been designed to study the corrosion behaviour and to generate data on three types of commercially important Cu‐Si alloys in 3.5 per cent sodium chloride and 1 per cent sodium sulphide solutions.

Abstract
This article examines relationships between capitalism and democracy as perceived by contending perspectives within the liberal capitalist‐liberal democratic tradition(s). Bentham and the Mills are taken as initiating both this tradition and the core elements of the debate within it. Pre‐Benthamite theories are first reviewed. Then, after discussion of Bentham and James Mill and of John Stuart Mill, Mill's late nineteenth and early twentieth century successors are examined. We then go on to consider hypotheses concerning the “exceptional” quality of relationships between capitalism and democracy in the United States. The penultimate section of the article adumbrates the main contours of mid‐twentieth century pluralist‐elitist theories. We conclude with a summary.

Abstract
Purpose
The purpose of this paper is to assess corporate social responsibility (CSR) implemented via social partnerships between professional sports teams and not-for-profit organizations according to current theoretical perspectives. Limited resources and outcomes often mean there is a gap between theory and practice, the implications of which are not well understood.
Design/methodology/approach
Five partnerships in Australian football were analyzed via case study methodology which incorporated interviews, analysis of websites, social media and annual reports.
Findings
Despite being used as a CSR tool, findings showed most organizations enter these arrangements to achieve instrumental outcomes. Further, such partnerships mostly operate at a basic stage often described as philanthropic. One partnership was seen as more advanced consisting of a workplace plan to enhance diversity.
Practical implications
It is advocated that managers adopt a more integrated partnership model consisting of formalized objectives, activity implementation, evaluation mechanisms, frequent interaction, top-level leadership involvement and promotion to sufficiently achieve CSR goals.
Originality/value
Addressing calls from past research into an examination of the variation of CSR in sports, this research is one of the first to compare multiple case studies to assess the strategic implementation of social partnerships in a professional sporting context. Accordingly, the study demonstrates how such partnerships can be evaluated against a prominent theoretical model, the Collaboration Continuum, enabling more robust social partnership strategies.

Abstract
Purpose
The authors discuss the value of portfolio and Black–Scholes (B–S)-option pricing model in fuzzy environment.
Design/methodology/approach
The B–S option pricing model (OPM) is an important role of an OPM in finance. Here, every decision is taken under uncertainty. Due to randomness or vagueness, these uncertainties may be random or fuzzy or both. As the drift µ, the degree of volatility s, interest rate r, strike price k and other parameters of the value of the portfolio V(t), market price S_0 (t) and call option C(t) are not known exactly, so they are treated as positive fuzzy number. Partial expectation of fuzzy log normal distribution is derived. Also the value of portfolio at any time t and the B–S OPM in fuzzy environment are derived. A numerical example of B–S OPM is illustrated.
Findings
First, the authors are studying some various paper and some stochastic books.
Originality/value
This is a new technique.

Abstract
Purpose
Building upon the attribution and brand resonance theories, this paper aims to investigate the effects of perceived corporate social responsibility (CSR) in higher education institutions on brand reputation, trust, equity and loyalty.
Design/methodology/approach
The data for this study were collected from international students of one public and one private university in Malaysia. Partial least squares-structural equation modelling was applied to analyse the data.
Findings
The findings revealed very strong effects of perceived CSR on brand reputation and trust. Moreover, the results determined the positive effects of brand reputation and trust on brand equity and loyalty. Additionally, findings support the positive indirect effects of perceived CSR on brand equity and loyalty through brand reputation and trust.
Originality/value
This study provides unique theoretical and practical contributions which can inform countries how to attract international students, particularly in post COVID-19 era.

Abstract
Purpose
The purpose of this study is to generate a better understanding of the nature of Corporate Social Responsibility (CSR) communication on social media. In fact social media are one of the most effective communication channels in contemporary business settings. Due to their inner characteristics, they should be the ideal channel for communicating CSR topics. Over the last 15 years, a variety of researches discussed the interplay between CSR and social media, resulting in a rather tangled body of knowledge.
Design/methodology/approach
This study proposes a scoping review of published academic literature at the intersection of these two research bodies (i.e. CSR and social media communication) to shed light on the nature of the communication, strategic challenges and practices, as well as their key factors and impact.
Findings
To date, academic research related to the nature of CSR on social media is fragmented and blurry. This research sheds light on the challenges of interactive social media communication in CSR and presents an account of key strategies, tactics and possible impacts for these challenging communication practices.
Originality/value
This research generates a better understanding of the nature of CSR communication on social media, strategic challenges and practices, as well as their key factors and impact. It is the tentative of generating a synthetic account of relevant literature in the field.

Abstract
Purpose
This paper aims to solve the uncertainty problem of hypersonic vehicle tracking control; an adaptive terminal sliding mode control (TSMC) method based on extended state observer (ESO) is proposed. The combination of adaptive techniques, TSMC and ESO offers an effective approach for managing uncertain systems.
Design/methodology/approach
The dynamic model of a hypersonic vehicle is transformed into two control-oriented subsystems. The control system design incorporates an adaptive technique, an ESO and a TSMC. The ESO estimates the primary uncertainties, while the adaptive technique determines the upper limit of secondary uncertainties. These estimates are used for the design of the TSMC law. In addition, the filter is used to generate the reference trajectory to improve the dynamic performance of the system. The stability of the closed-loop system is proved by the Lyapunov stability theory.
Findings
A robust control system for hypersonic vehicles is developed with guaranteed stability and strong adaptability to various uncertainties such as parameter variations, external disturbances and actuator faults. Furthermore, the proposed system demonstrates enhanced dynamic performance compared to observer-based sliding mode control. Specifically, for the velocity and altitude tracking control, the settling time of the proposed sliding mode control is approximately 100 s and 70 s shorter than that of the observer-based sliding mode control, respectively.
Originality/value
Different from the single equivalent treatment, various uncertainties here are classified and treated with different strategies, which improves the disturbance rejection ability of the control system. This ability is of great significance for enhancing the autonomy, adaptability and reliability of hypersonic vehicles in extreme environments.

Abstract
Purpose
This work aims to examine the communication on Twitter of the most responsible companies in Spain to identify the topics covered on corporate social responsibility (CSR) from the perspective of happiness and social marketing. In addition, the profiles of the messages that show an association with the impact of the messages have been identified.
Design/methodology/approach
An empirical analysis of the Twitter posts of Spain's ten most responsible companies has been carried out. The methodology of this work combines data mining techniques, sentiment analysis and content analysis, both from a quantitative and qualitative approach.
Findings
The results show that most brand tweets do not deal with CSR-related topics. The topics they address the most are those related to sports and the weather. From the perspective of social marketing, conversational-type tweets are the most published and have achieved the most significant reaction from the public. In addition, four messages' profiles have been identified based on the company and the emotional connotation associated with the impact, giving rise to more outstanding promotion of social causes.
Originality/value
Our main contribution to this work has been to value positive communication and social marketing to promote better CSR on Twitter. In this sense, it has been verified that there is a relationship between the public's reaction, the affective connotation and the company that issues the messages.

Abstract
Purpose
The purpose of this paper is to explore the synergic effect of wild turmeric (Curcuma Aromatica Salisb.) and holy basil (Ocimum Tenuiflorum L.) combination herbal extracts treatment on the moisture management properties of cotton, lyocell and micro-denier single jersey knitted fabrics and the factors affecting it, which is intended for the development of healthcare apparel products.
Design/methodology/approach
The pre-treated single jersey knitted fabrics of cotton, lyocell and micro-denier polyester fabrics were given finishing treatment with the wild turmeric (Curcuma Aromatica Salisb.) and holy basil (Ocimum Tenuiflorum L.) combination herbal extract proportions of 100%:0%, 75%:25%,50%:50%; 25%:75% and 0%:100%. The D-optimal factorial design developed using Design Expert software was used for the study. The finishing treatments were carried out using the pad−dry−cure method. The aim of the work is to find out the influence of combination herbal extract proportion, textile material and their interaction effect on the moisture management properties.
Findings
The ANOVA results revealed that the overall moisture management properties of single jersey knitted fabrics are influenced by the material type, combination herbal extract proportion and the interaction between material type and the combination herbal extracts proportion. The overall moisture management properties of combination herbal extracts treated cotton single jersey fabrics are found to be better than that of lyocell and micro-denier polyester fabrics due to their excellent accumulative one-way transport capability after the finishing treatment. Among the combination herbal extract proportions, 50:50 per cent combination herbal extract proportion was found to be better than other proportions.
Originality/value
The study on the moisture management properties of combination herbal extracts of wild turmeric (Curcuma Aromatica Salisb.) and holy basil (Ocimum Tenuiflorum L.) is a novel attempt to explore the synergic effect of active constituents in both the herbs.
