Abstract

Purpose

The aim of this study was to determine the effectiveness of promoting peer support to reduce depression, anxiety and stress among migrant construction workers in Singapore.

Design/methodology/approach

This longitudinal study drew participants from migrant workers of various nationalities in the construction sector in Singapore. Baseline data pertaining to depression, anxiety and stress was established using the DASS-21 questionnaire, and salient covariates such as demographic factors and work environment factors recorded using suitable questionnaires. Intervention was training of participants on peer support techniques, supplemented by episodic support by trained counsellors. At the end of 6 months, DASS-21 was again deployed to obtain the post-results. Comparison of baseline with post-results data was performed to evaluate effectiveness of the peer support intervention.

Findings

Statistically significant reduction was observed in measures of all the three parameters studied, namely, depression, anxiety and stress. A decrease of 3.3 (95% CI:2.3 to 4.3) points in mean depression score, a decrease of 2.6 (95% CI: 1.6 to 3.7) points in mean anxiety score and a decrease of 2.7 (with 95% CI: 1.6 to 4.0) points in mean stress scores on the DASS-21 scale were recorded. Conclusions: Peer support is effective in improving mental health of migrant workers in the construction sector in Singapore. This intervention should be considered among other measures to improve their welfare.

Originality/value

This is the first paper that talks about the mental health of migrant workers pre-COVID and hence would be a strong paper for the future comparative studies for pre-and post-COVID periods. This is the first paper that addresses the benefits of peer-support among migrant workers to improve their mental wellbeing.

Abstract

Purpose

Exposure to poor indoor air in refurbished buildings is a matter of health concern due to the growing concentrations of various contaminants as a result of building airtightness without amendment of ventilation, or the use of building materials such as glue, paint, thinner and varnishes. Recent studies have been conducted to measure indoor air pollutants and assess the health risks affecting the quality of life, productivity and well-being of human beings. However, limited review studies have been recently conducted to provide an overview of the state of knowledge. This study aims to conduct a scoping review of indoor air quality (IAQ) in the context of refurbished or energy-retrofitted buildings.

Design/methodology/approach

A systematic screening process based on the PRISMA protocol was followed to extract relevant articles. Web of Science, Scopus, Google Scholar and PubMed were searched using customised search formulas. Among 276 potentially relevant records, 38 studies were included in the final review covering a period from 2015 to 2022.

Findings

Researchers mapped out the measured compounds in the selected studies and found that carbon dioxide (CO2) (11%) and total volatile organic compounds (11%) were among the most commonly measured contaminants. Two trends of research were found including (1) the impact of ventilative properties on IAQ and (2) the impact of introducing building materials on IAQ.

Originality/value

The contribution of this study lies in summarising evidence on IAQ measurements in refurbished buildings, discussing recent advancements, revealing significant gaps and limitations, identifying the trends of research and drawing conclusions regarding future research directions on the topic.

Abstract

Purpose

Environmental dynamics affect all sectors, and retailing is no exception. Scholarships reveal that, in such turbulent times, entrepreneurial characteristics are essential for business. In academic research, entrepreneurial characteristics like entrepreneurial orientation (EO) and entrepreneurial competence (EC) are seldom evaluated for retailers. This study aims to decode the impact of small retailers’ EO and EC on firm business performance (BP). It also traces the mediation effect of EC in the relationship between EO and BP.

Design/methodology/approach

The study executed among 740 small retailers is a pioneering work to trace EO’s efficacy via EC on the retailer’s BP. The present research is a primal work in the Indian context. This work redesigns the EC scale to suit the retail context and evaluate its mediation role in the EO and BP relationship.

Findings

Examining the mediation model through structural equation modelling (SEM) adds empirical evidence to entrepreneurial value creation (EVC) theory and throws light on the indispensable qualities required for small business retailers. The outcomes of the SEM model portray that there is an association between the EO, EC and BP.

Research limitations/implications

This study, though carried out methodically, it is constrained by the ensuing intricacies. The investigation was limited to the small- and medium-retailers engaged in retailing with a floor space from 500 to 5,000 square feet. All three constructs used in the study are measured using the self-reported perceptual scale, which infuses the subjectivity in the data. Exploring the EO and EC of widely dispersed retailers, examining the entrepreneurial character of large-format independent retailers and evaluating financial performance measures through retailers will add value to the study in future.

Originality/value

The study verified the central role of EC in the intangible resource-reward relationship. Among the five pillars of EVC theory, the role of intention and external finance are not considered in this work. The present work explored the EO and EC of existing retailers, and hence intention is excluded. The study concentrates on small retailers, and the role of external financing is not explored. Mishra and Zachary (2014b) opined that the EVC process should be studied in different context and listed out several prepositions. Considering the role of intention and external financing and studying several prepositions spelt out in the theory in varying contexts will throw more lights on the EVC process.

Abstract

Purpose

In today’s technology-led volatile business environment all established businesses are trembling and retailing is no exception. Exploration of the entrepreneurial side of retailers will expose the essential attitudes to survive in the new world order. The present study is an endeavor towards this end.

Design/methodology/approach

In this descriptive research, a pre-tested entrepreneurial orientation questionnaire constructed by De Nobrega (2012) was adopted, and it was fine-tuned to suit for the retail environment. Initially, an exploratory study was organized, and it was followed by confirmatory factor analysis. Data collected were analyzed with SPSS 23.0, and the conceptual model was validated in AMOS 23.0.

Findings

The study evinces that the retailer’s entrepreneurial orientation is induced by five factors, namely, autonomy, risk-taking, innovation, competitive aggressiveness and pro-activeness. The study exposes the five dimensions and their ascendancy on business performance.

Research limitations/implications

The study is operationalized in a small sample, confined to two types of trade, limited to small and medium retailers in Chennai and all the constructs are measured with the help of perceptual self-reporting scales.

Practical implications

The study highlights that the art of spearheading retail business performance lies in attitude orientation. This work will propel retailers and trade bodies to nurture the entrepreneurial orientation.

Social implications

The study emphasizes that boosting entrepreneurial mindset of retailers will enable them to achieve business progress and protects the grass root sector of the society.

Originality/value

This work is the very first study to identify and evaluate the impact of five-dimensional entrepreneurial orientation construct on small and medium retailer’s business performance. The present study is a pioneering empirical contribution to the Indian context.

Abstract

Introduction: Historically, the corporate governance (CG) framework was designed primarily to safeguard the economic interests of shareholders, as a result of political and legal interventions, developing into an effective instrument for stakeholders and society in general.

Purpose: The core objectives of the study include: identifying journals/publications responsible for publishing CG studies in India, key CG issues covered by CG researchers, the amount of high-impact CG literature across different time periods, sectors/industries covered by CG researchers and different research instruments (quantitative or qualitative) used in CG studies in India.

Design/methodology: The chapter used a sample of 130 corporate governance studies that fulfil the selection criteria, drawn from the repository of over 100 reputed journals that are either recognised by the Australian Business Deans Council (ABDC) or indexed by SCOPUS. A systematic literature review has been carried out pertaining to CG issues in India, based on various statistical tools, data, industries, research outlets & citations, etc.

Findings: The results show an overwhelming number of studies have assessed the relationship between CG variables and firm performance, which could be measured through a variety of performance metrics such as ROA and ROI. Apart from empirical analysis, many conceptual studies use repetitive basic statistical tools like descriptive statistics or regression analysis. The chapter offers insights into current achievements and future development.

Originality/value: This bibliometric study is a useful guide for policymakers, corporate leaders, research organisations and management faculty to draw insights from work produced by eminent researchers in GC in India.

Abstract

Purpose

The mischievous nodes that defy the standard corrupt the exhibition of good nodes considerably. Therefore, an intrusion discovery mechanism should be included to the mobile ad-hoc network (MANET). In this paper, worm-hole and other destructive malignant attacks are propelled in MANET.

Design/methodology/approach

A wireless ad-hoc network also called as mobile ad-hoc network (MANET) is a gathering of hubs that utilizes a wireless channel to exchange information and coordinate together to establish information exchange among any pair of hubs, without any centralized structure. The security issue is a major difficulty while employing MANETs.

Findings

Consequently, the attacks due to the malicious node activity are detected using Hybrid Reactive Search and Bat (HRSB) mechanism to prevent the mischievous nodes from entering the network beneath the untruthful information. Moreover, the attack detection rate and node energy are predicted for determining the lifetime of the node.

Originality/value

The simulation outcomes of the proposed HRSB technique are evaluated with the prevailing methods. The comparison studies have proven the efficacy of the current research model by attaining high attack detection rate and achieving more network lifetime.

Abstract

Purpose

Eri is a short-stapled fibre that possesses an excellent soft feel and warmness to the wearer. Investigation of thermal comfort and moisture properties of Eri silk fabric provides the enhanced commercial scope for Eri silk-based clothing.

Design/methodology/approach

To examine the impact of process factors on thermal and moisture properties, three different single knit Eri silk structures were made, each with a different loop length and yarn count. Three different linear densities of Eri silk spun yarn (15, 20 and 25 tex) were selected. Three distinct knitted constructions, including plain jersey, popcorn and cellular blister, were created, along with two different loop lengths.

Findings

The novel cellular blister structure has shown appreciable thermal comfort properties than the other two structures. Yarn fineness and loop length were significant with most of the thermal comfort properties.

Research limitations/implications

In recent times the Eri silk production is completely domesticated, so the new demand can easily be met by the producers. This research will create a new scope for Eri silk fibres in sportswear and leisure wear.

Originality/value

This study was conducted to explore the influence of knit structure, loop length and yarn count on the thermal comfort properties of the clothing.

Abstract

Purpose

The internet has completely merged into contemporary life. People are addicted to using internet services for everyday activities. Consequently, an abundance of information about people and organizations is available online, which encourages the proliferation of cybercrimes. Cybercriminals often use malicious links for large-scale cyberattacks, which are disseminated via email, SMS and social media. Recognizing malicious links online can be exceedingly challenging. The purpose of this paper is to present a strong security system that can detect malicious links in the cyberspace using natural language processing technique.

Design/methodology/approach

The researcher recommends a variety of approaches, including blacklisting and rules-based machine/deep learning, for automatically recognizing malicious links. But the approaches generally necessitate the generation of a set of features to generalize the detection process. Most of the features are generated by processing URLs and content of the web page, as well as some external features such as the ranking of the web page and domain name system information. This process of feature extraction and selection typically takes more time and demands a high level of expertise in the domain. Sometimes the generated features may not leverage the full potentials of the data set. In addition, the majority of the currently deployed systems make use of a single classifier for the classification of malicious links. However, prediction accuracy may vary widely depending on the data set and the classifier used.

Findings

To address the issue of generating feature sets, the proposed method uses natural language processing techniques (term frequency and inverse document frequency) that vectorize URLs. To build a robust system for the classification of malicious links, the proposed system implements weighted soft voting classifier, an ensemble classifier that combines predictions of base classifiers. The ability or skill of each classifier serves as the base for the weight that is assigned to it.

Originality/value

The proposed method performs better when the optimal weights are assigned. The performance of the proposed method was assessed by using two different data sets (D1 and D2) and compared performance against base machine learning classifiers and previous research results. The outcome accuracy shows that the proposed method is superior to the existing methods, offering 91.4% and 98.8% accuracy for data sets D1 and D2, respectively.

Abstract

Purpose

Pearl millet (Pennisetum glaucum) is a rich source of nutrients as compared to the major cultivated cereal crops. However, major factors which limit its utilization are the presence of anti-nutritional factors (phytate, tannins and polyphenols) which lower availability of minerals and poor keeping quality because of higher lipase activity. Therefore, this paper aims to focus on the impact of different processing methods on the nutrient composition and anti-nutritional components of pearl millet.

Design/methodology/approach

This is a literature review study from 1983 to 2017, focusing on studies related to pearl millet processing and their effectiveness in the enrichment of nutritional value through reduction of anti-nutritional compounds.

Findings

From the literature reviewed, pearl millet processing through various methods including milling, malting, fermentation, blanching and acid as well as heat treatments were found to be effective in achieving the higher mineral digestibility, retardation of off flavor, bitterness as well as rancidity problems found during storage of flour.

Originality/value

Through this review paper, possible processing methods and their impact on the nutrient and anti-nutrient profile of pearl millet are discussed after detailed studied of literature from journal articles and thesis.
