Abstract

Purpose

Functionalization of organic cotton fabrics (OCFs) by in situ deposition of chitosan reduced-stabilized silver nanoparticles (AgNPs). No other toxic chemicals used to warrant an ecofriendly synthesis protocol. Human toxicity of silver systematically avoided to use as textile clothing. Primary colors (nearly-red, yellow and blue) were imparted on OCFs via localized surface plasmon resonance (LSPR) of AgNPs. Decent mechanical properties and laundering durability in terms of antibacterial/fastness test improved mechanical properties.

Design/methodology/approach

Silver nanoparticles can be synthesized by using silver nitrate along with commercially available chitosan. Due to the surface LSPR property of silver nanoparticles, it exhibits versatile colors depending on the synthesizing procedures. The coloration occurs due to the electrostatic interaction between the AgNPs and chitosan-treated OCF. The nanotreated fabrics provide excellent mechanical properties with improved antibacterial effects.

Findings

X-ray fluorescence (XRF) analysis quantifies the developed materials in the substrates. Scanning electron microscopy (SEM) characterization indicates the appearance and morphologies of silver nanoparticles into the fabric surface after the coloration process. It proves that the treated cotton knit fabric exhibits the LSPR optical features of AgNPs. The antibacterial and mechanical properties confirm the improved functionality of products.

Originality/value

Improved mechanical properties, antibacterial performances and coloration effects on organic cotton substrates in terms of chitosan-mediated nanosilver are not yet studied.

Abstract

Purpose

Studies on remarriages based on census data are not available in Bangladesh. Moreover, questions like why the remarriage rate is declining in Bangladesh despite the increasing trend of divorce rate and what factors are associated with this declining trend of remarriage are not answered yet. Thus the purpose of this study is to assess the prevalence of divorces and the extent to which this has influenced the likelihood of remarriage in Bangladesh.

Methodology/approach

Univariate, bivariate, and multivariate analyses have been performed by analyzing the most recent and largest sample census data of ever married men and women aged 10 years and above collected in 2011.

Findings

The prevalence of remarriage is low in Bangladesh but more common in rural places of residence, substantially larger in slums when compared with non-slums, among Bengali ethnic people, rent-free tenancy, the age group of 45 years and over, the male population, people of Muslim religion, who have no education, and poorest wealth quintile. Muslim religion, slum dwelling status, employed status, media exposure, and urban residence stand out as the major determinants in terms of remarriage. Women having higher education and the richest quintile of households are less likely to be remarried than those who have lower education and are from the poorest wealth quintile background. Males who remarry also followed the same pattern. But remarriage is higher among both the divorced males and females as compared to widowed males and females. Strategic targeting and responsive social policies are needed to be implemented toward the differential pattern of remarriage by sub-groups of the population and their vulnerabilities in relation to their marital status and marital relation, to understand remarriage dynamics in Bangladesh.

Abstract

Purpose

The purpose of this paper is to present the results of studies on the reaction of metal oxides such as Cr2O3 and Al2O3 with Na2SO4 in flowing SO2 (g) at 1,100 and 1,200 K.

Design/methodology/approach

The oxides chosen for the studies were initial scaling products during the oxidation of industrial alloys and invariably are involved in hot‐corrosion reactions in the presence of molten salts. The thermo‐gravimetric studies for the system were carried out as a function of Na2SO4 in the mixture. The different constituents in the reaction products were identified by XRD analysis and morphologies of the reaction products were discussed on the basis of optical metallography and scanning electron microscopic studies. The pH and conductivity of the aqueous solutions of reaction products were measured and an attempt made to functionalize these parameters with Na2SO4 concentration in the mixture. Quantitative estimation of the soluble metal was carried out using an atomic absorption spectrophotometer. The formation of products was investigated by thermodynamic computation of free energies of the reactions and the study of relevant phase stability diagrams.

Findings

Looking at the complex nature of the reactions, it is difficult to generalize the conductance studies, as many complex species are liable to hydrolyze in the aqueous solution. However, the break in few curves at certain mole fraction of Na2SO4 indicates the presence of soluble complex species.

Originality/value

The paper provides information regarding the reaction between a pertinent oxide and Na2SO4 and proper identification of reaction products, useful for understanding the occurrence and importance of fluxing reactions and in the interpretation of hot corrosion mechanism and the development of new protective materials.

Abstract

Purpose

The purpose of this paper is to develop the theory of environmentally responsible behavior by extending the theory of planned behavior to empirically examine waste reduction behaviors among young coastal tourists in Bangladesh.

Design/methodology/approach

Through review of literature, in-depth interviews and survey, the study is conducted. Initial survey collects 355 data, which is used for exploratory factor analysis to develop constructs and its measurement items. After preparing the formal survey questionnaires, another survey is conducted and collected 403 usable responses. The subsequent valid responses are used for confirmatory factor analysis through structural equation modeling, using Smart PLS 3.3.3.

Findings

The results of this study reveal that waste reduction behavior is significantly affected by waste reduction intention, and then subsequently waste reduction intention is significantly affected by environmental concern, climate change concern and healthy environmental norms of young coastal tourists in Bangladesh.

Practical implications

The findings of the study will benefit industry operators and policymakers by understanding the factors that are crucial for influencing young costal tourists’ environmentally responsible behaviors (i.e. waste reduction behaviors). Eventually, the findings may assist industry operators and policymakers to develop strategies to attract more young tourists to the coastal tourist destinations in Bangladesh.

Originality/value

The importance of environmentally responsible behavior has received a significant attention in present decade. Consistent with this phenomenon, this study uniquely develops the theory of environmentally responsible behavior and establishes the link between environmental concern, climate change concern, healthy environmental norms, waste reduction intention and waste reduction behavior in coastal tourism domain in Bangladesh.

Abstract

Purpose

This study aims to identify factors affecting travellers' behavioural intentions regarding beach destinations in Bangladesh. The study also examines how destination experience and satisfaction mediate the nexus between destination service factors and travellers' behavioural intentions.

Design/methodology/approach

A self-administered survey was carried out to gather data from 375 people who had visited the beaches in Cox's Bazar. Data were examined using partial least squares structural equation modelling (PLS-SEM) to evaluate the hypotheses.

Findings

The destination experience mediates the relationship between destination service factors and complaint intention but does not mediate the relationship between destination service factors and word of mouth (WOM). Moreover, destination satisfaction mediated the relationship between destination service factors and WOM, along with complaint intention.

Practical implications

This study's findings can be utilised by the Bangladeshi destination management to increase the number of tourists by instituting and maintaining improved destination service features in popular tourist destinations.

Originality/value

This is one of few studies on beach tourism destinations in Bangladesh that comprehensively overviews destination service factors and their influence on tourists' behavioural intentions, with a special emphasis on the mediating roles of destination experience and destination satisfaction.

Abstract

Purpose

Ukraine hosts thousands of international students for educational tourism, of which more than 18,000 Indian medical students were compelled to escape Ukraine under emergency conditions of war. This paper aims to examine their intention to return to Ukraine to complete their education based on an integrated theory of planned behaviour (TPB) framework with added constructs, i.e. risk perception, career anxiety, rescue and relief memory.

Design/methodology/approach

The data were collected from 26 February 2022 to 30 June 2022 in two phases and two modes. It was ensured that the respondents were strictly confined to Indian medical students who had travelled to Ukraine for educational tourism. SPSS 25 and AMOS 23.0 were used to analyse the data. The hypotheses proposed were statistically tested.

Findings

The analysis reveals that the extended TPB model resulted in a strong model and the empirical findings corroborate that the students’ attitude, subjective norms, perceived behavioural control and career anxiety significantly and positively influence the students’ revisit intention (RI) while risk perception and rescue and relief memory have a negative influence on the RI.

Research limitations/implications

The study provides timely insights and implications to the Ukrainian tourism industry, particularly educational tourism business and medical institutions under the present turmoil, which can also act as blueprint research for destinations with a similar unstable political background.

Originality/value

The primary value of this research work is that it provides an understanding of the intention of medical students (educational tourists) towards revisiting the war-hit destination of Ukraine.

Abstract

Purpose – We build a theoretical lens that draws on an emerging theory of positive work relationships to examine whether constructive emotional expressions in work relationships influence changes in individuals' affective commitment to their organization.

Design/methodology/approach – Using longitudinal data collected from full-time employees, we employed a latent-difference-score (LDS) approach to examine whether changes in emotional carrying capacity could account for changes in organizational commitment.

Findings – The findings support this hypothesis and suggest a new perspective on the ways in which a change in relationship capacity may create changes in people's commitment to an organization.

Research limitations – The main limitation concerns the use of self-report, albeit time-lagged, data.

Practical implications – Developing higher levels of employee affective commitment is a key challenge for many organizations. Our study can help managers in recognizing the importance of building a relational space in which employees are able to express emotions frequently and openly, as well as engaging with other employees in listening to their emotional experiences and responding in a constructive manner.

Originality/value – This study contributes to an emergent body of literature that adopts a positive psychology lens to the study of employee experiences at work, by investigating the capacity to express emotions in general and its influence on people's affective commitment to the organization.
