Abstract

Purpose

The main purpose of taking up this work was to see the influence of metallic nanoparticles on various fabric properties. This paper emphasizes on mechanical, aesthetic and anti-bacterial properties of the polyester, cotton and polyester cotton-blended fabric samples.

Design/methodology/approach

Three fabrics, 100 per cent polyester, 100 per cent cotton and polyester cotton-blended (50:50), were procured from the market. They were subjected to mild washing treatment so that the fabrics could be impregnated with copper (Cu) nanoparticles following standard procedure. The characterization of Cu nano-loaded textiles has been done using various techniques such as scanning electron microscopy for surface morphology, X-ray fluorescence spectrometer for elemental analysis and Fourier transform infrared spectroscopy for chemical composition. However in this paper, the focus is on various fabric properties and influence of this treatment on them. Antimicrobial activity was measured as per AATCC 100 quantitative method.

Findings

The structural properties showed changes but not major ones. The impregnation of Cu nanoparticles is nothing but a chemical treatment, and it is not uncommon to find reduction in the mechanical properties of the specimen. Here also, the mechanical properties were studied but did not reveal any significant change. The aesthetic properties for cotton fabrics showed an improvement. Improvement in the anti-bacterial activity was observed for all the fabric samples but the improvement in cotton fabric is worth mentioning. Thus, nano treatment imparts anti-bacterial property without hampering the mechanical properties of the parent textiles.

Research limitations/implications

It is usual to find changes in the various properties of the materials subjected to nano treatment or treatment of any sort. Though the fabric samples were subjected to similar treatment, the quantity of nanoparticles taken up by each of them was different. The reason behind this could be the difference in the crystallinity of the fabric samples. Polyester fabric showed the highest resistance, as it was least affected by the nano treatment given. Cotton fabrics composed of cotton fibers are amorphous in nature, hence showed better take-up and hence were more affected by the said treatment.

Practical implications

Cotton fabrics are the most favored fabric, especially in regions with hot climatic conditions. Even though these fabrics are very sought after, they have a major drawback related to the aesthetic appeal of the fabric. These fabrics have very poor resistance to the crease formation, as well as their ability to recover from the external deformation. But the study conducted on the fabric samples has shown favorable results for the cotton fabric. A significant improvement in their aesthetic and anti-bacterial activity was found. At present, textiles with nano finishing fall in niche market due to its higher cost. But finishing with in-house Cu nanoparticles may open up hygiene textiles for consumers at affordable rates.

Social implications

Cotton is still the most popular natural fiber in most of the tropical and sub-tropical regions. People located in these places have a natural urge to wear fabrics made from cotton fibers. Due to the hot weather, sweating is natural. However, this tends to keep the skin in humid state resulting in various skin problems, as cotton is also prone to bacterial attack. But this work has shown positive results, meaning to say that cotton fabrics show improved resistance to the bacterial activity. Hence, its suitability for hygiene applications may soon become a reality.

Originality/value

It is true that a lot of work is being reported on nano materials and their application to textiles for various reasons. Recently, many reports are available related to finishing of textiles using nanoparticles. However, most of the researchers are using silver nanoparticles for the same. In this work, use of in-house Cu nanoparticles has been done to treat fabric samples, which is more economical than silver nano. Also quantity required to meet desired property with Cu nanoparticles is less than the conventional treatment. This work is a sincere attempt to prepare hygienic common textiles at economical rates using continuous application technique which offers durable efficacy against human pathogenic bacterium.

Abstract

Purpose

The purpose of this paper is to report a case study carried out to assess the agility and identify obstacles to agility in a supply chain. A human perception-based framework is used for the calculation of agility. The case study was carried out in a North India-based manufacturing organization.

Design/methodology/approach

In this study, the concept of a multi-grade fuzzy logic approach is used. Using this concept, the overall agility index has been determined. The fuzzy logic approach has been used to overcome the disadvantages such as impreciseness and vagueness using a scoring method.

Findings

From the analysis, it is observed that the organization on which the study was performed is “very agile.” After evaluating the agility level, the fuzzy performance importance index is calculated, which helps to identify the barriers of agility in the supply chain. These barriers help decision makers to implement appropriate improvement measures for improving agility level. Overall, 11 barriers were identified in the study.

Research limitations/implications

Managers of the contemporary manufacturing organization have to measure the agility level of the organization and identify barriers to agility in order to survive in a competitive environment. The obstacles identified in this study are used to improve the performance of the organization. The enterprise should improve on the weak areas in order to achieve the highest agility level.

Originality/value

The agile supply chain (ASC) enablers proposed by previous researchers are not sufficient for the evaluation of agility of a supply chain. There are a few more ASC enablers such as customer satisfaction, flexibility and adaptability that also play a vital role in making a supply chain agile. Adding these three ASC enablers, a total of seven ASC enablers along with their attributes are being considered for the development of a conceptual model.

Abstract

Purpose

Agility is the ability of an organization to adjust its supply chain tactics and operations to respond quickly against altering business environments such as fluctuating demand pattern, supply chain disruption and global competition. An agile organization must possess a promising capability of swiftly responding to dynamic conditions while being cost-effective without compromising the efficiency. Such high-performance adaptability necessitates the role of supply chain managers to maximize the agility of the supply chain through the efficient use of input resources. Therefore, the purpose of this study to reveal a new decision support tool that would allow the key decision-makers to maximize the agility of the supply chain while deploying the input resources more effectively.

Design/methodology/approach

In present study, an integrated approach of popular analytic hierarchy process (AHP) and goal programming (GP) has been adopted as a potential solution methodology. AHP has been implemented to allocate the local and global weights to decision variables, whereas GP incorporates the AHP weights into the desired model.

Findings

It was found that the proposed decision support tool restricts the value of the decision variables for maximizing the agility and optimizing the usage of input resources. The results obtained from the model validate the objective of achieving targeted agility level within the available resource limitations.

Research limitations/implications

The decision support tool developed in the proposed study offers a systematic and effectively simple approach to supply chain managers with a goal of identifying the degree of focus under each decision variable in the respective manufacturing organizations.

Originality/value

A novel decision support tool has been developed known as an agility control system), which helps the decision-maker to achieve the required agility in the supply chain by controlling the decision variables.

Abstract

Purpose

The purpose of this study is to categorize and analyse the drivers and barriers of Lean Manufacturing (LM) and subsequently, based on the structural model develop a house of lean management which will give an idea to the academicians and practitioners about the factors that are critical to implement lean practices in an organization.

Design/methodology/approach

A list of drivers and barriers was prepared based on the literature review and opinions from experts. Total Interpretive Structural Modelling (TISM) was utilized to build a structural hierarchy of the drivers and barriers of LM. The structural hierarchy was utilized to build the house of lean management.

Findings

Based on the hierarchy developed, the elements (drivers and barriers) of LM are classified into three groups: bottom-level, middle-level and top-level elements. To develop a house of lean management, bottom-level of elements were considered as a foundation, middle-level elements were considered as pillars and top-level elements were considered as a beam. Finally, foundation, pillars and beam of the house were used to support the roof (which is value to customers and profitability to firm).

Practical implications

The outcome of this research can assist researchers as well as practitioners to enhance the significant drivers and to reduce the impact of hazardous barriers for the better implementation of lean practices.

Originality/value

This research is a novel approach, as it visibly demonstrates both the drivers and barriers, examines the interrelationships among them in order and shows them pictorially as the house of lean management.

Abstract

Purpose

The purpose of this paper is to attempt the buckling analysis of a laminated composite skew plate using the C0 finite element (FE) model based on higher-order shear deformation theory (HSDT) in conjunction with minimax probability machine regression (MPMR) and multivariate adaptive regression spline (MARS).

Design/methodology/approach

HSDT considers the third-order variation of in-plane displacements which eliminates the use of shear correction factor owing to realistic parabolic transverse shear stresses across the thickness coordinate. At the top and bottom of the plate, zero transverse shear stress condition is imposed. C0 FE model based on HSDT is developed and coded in formula translation (FORTRAN). FE model is validated and found efficient to create new results. MPMR and MARS models are coded in MATLAB. Using skew angle (α), stacking sequence (Ai) and buckling strength (Y) as input parameters, a regression problem is formulated using MPMR and MARS to predict the buckling strength of laminated composite skew plates.

Findings

The results of the MPMR and MARS models are in good agreement with the FE model result. MPMR is a better tool than MARS to analyze the buckling problem.

Research limitations/implications

The present work considers the linear behavior of the laminated composite skew plate.

Originality/value

To the authors’ best of knowledge, there is no work in the literature on the buckling analysis of a laminated composite skew plate using C0 FE formulation based on third-order shear deformation theory in conjunction with MPMR and MARS. These machine-learning techniques increase efficiency, reduce the computational time and reduce the cost of analysis. Further, an equation is generated with the MARS model via which the buckling strength of the laminated composite skew plate can be predicted with ease and simplicity.

Abstract

Purpose

The Indian manufacturing sector currently contributes 16–17% to gross domestic product (GDP) and gives employment to around 12% (2014) of the country's workforce. Among the various initiatives planned under Atma Nirbhar Bharat and “Make in India”, the Indian government aims to increase the share of the manufacturing sector to country's GDP to 25% by 2025. To ensure sustainable growth of the Indian manufacturing industries in global market, successful and implementation of strategies such as lean manufacturing, green manufacturing along with six sigma are crucial. This research aims at identification and analysis of barriers to successful implementation of integrated Lean Green Six Sigma (LG&SS) strategies.

Design/methodology/approach

Based on an evaluative literature review and expert's opinion, this research identifies 18 barriers to lean, green and six sigma implementation in the manufacturing industry in India. The inter-relationships among the barriers is identified using an integrated approach of ISM (interpretive structural modelling) and Fuzzy Matrice d’Impacts Croisés Multiplication Appliquée á un Classement (MICMAC).

Findings

ISM helps to derive key managerial insights and implementation plan based on the identified inter-relationships among the barriers. Fuzzy MICMAC analysis classifies the barriers into four categories, namely, autonomous, driver, dependent and linkage to understand their relative impact on the implementation of LG&SS practices in the Indian manufacturing industry. “Lack of cooperation and mutual trust between management and employees”, “The scarcity of time and work pressure”, “lack of continuous improvement work culture” and “lack of cooperation from suppliers” that forms the top most level of the model. “Weak legislation” is a highly significant barrier to LG&SS implementation in the Indian manufacturing industries.

Practical implications

It is expected that the findings of this research will help the Indian manufacturing industry to derive a sustainable competitive advantage through an effective implementation of LG&SS practices.

Originality/value

This study can be seen as the first attempt in investigating barriers to successful implementation of lean, green and six sigma strategies in the Indian manufacturing industries using ISM and fuzzy MICMAC analysis.

Abstract

Purpose

The purpose of this paper is to evaluate the role of family support, co‐worker support, supervisor support, work‐life balance policies (WLBPs), work‐family culture and job characteristics, as the predictors of work‐to‐family (WFE) and family‐to‐work (FWE) enrichment. In addition, it explored whether such effects were gender specific by examining the moderating effect of gender.

Design/methodology/approach

Data were obtained from a sample of 485 managers in India. Analysis was done using multiple regressions.

Findings

Analyses revealed that family support, co‐worker support, supervisor support, WLBPs, work‐family culture and job characteristics predicted WFE while family support and job characteristics predicted FWE. Little moderating influence of gender was found. Gender moderated the relationship between WLBPs and WFE such that the relationship between the two was stronger for women as compared to men. Similarly, gender moderated the link between job characteristics and WFE such that the relationship between the two was stronger for men than women.

Research limitations/implications

The cross‐sectional design of the study constrains inferring conclusions regarding causality.

Practical implications

WLBPs have to be offered to women executives and organizations do have to make jobs more enriching in order to increase the level of WFE among women and men, respectively.

Originality/value

The construct work‐family enrichment examined in this paper reflects an understanding of work‐family interface from a newer lens in a novel socio‐cultural context and demonstrates the moderating role of gender.

Abstract

Purpose

The purpose of this paper is to provide an empirical investigation into the mediating effect of high-performance work systems (HPWS) on health harm (HH). The paper also examines the role of perceived organizational support (POS) and its indirect effect on work intensification (WI) and HH through HPWS. Further, the implications of the HH on individuals, organizations, families and societies are also presented. Recognizing the need for sustainable human resource management (HRM) practices that drive employee well-being and reducing HH is also highlighted.

Design/methodology/approach

Data for the study were collected using four established scales. The data collected from 345 executives were analyzed using the SPSS 25.0 Version and Amos 21.0.

Findings

The study confirmed that work intensification causes HH. The results also indicate the significant mediation of HPWS and the moderation of POS between WI and HH, thus suggesting the inevitability of HR intervention for implementing sustainable HRM practices, which reduce the negative harm of the work.

Research limitations/implications

Data were collected from executives working in IT organizations in India. However, IT work exhibits broadly similar technology/platforms across the world and hence, applicable to the other contexts as well.

Practical implications

The study suggests that organizations should formulate policies and initiate interventions toward the care of employees, motivating toward higher performance and support them to prevent HH of work. It is difficult to categorize what comprises the care of employees in the current context of HPWS and treating employees as an end in itself. Generally, it is seen in terms of health and safety, work–life balance, remuneration, workload, job role and job design. People are core to sustainable development, and the HR must design and develop systems so that the organization can retain a healthy and productive workforce from a sustainability perspective. Moreover, sustainable work performance is a function of high resource levels of employees (energy, time and competences) and the allocation of resources, leading to resource regeneration. Hence, organizations need to source from a variety of sources and balance it for the sustainable performance of employees.

Originality/value

The HRM literature reveals the positive effect of POS on employee health, but studies that investigated the adverse impact of POS are notably absent. The study bridges this gap and is novel, as it explores the moderating role of POS on HPWS and HH and reaffirms the need for building sustainable organizations and sustainable HRM practices. Moreover, the paper provides contextual support to the literature, where studies relating to sustainable HRM practices in developing countries like India are absent.

Abstract

The role of social networks is central to the phenomenon of employment and ownership in ethnic businesses, ethnic enclaves, and more generally ethnic economies. Social capital within migrant or co-ethnic social networks is generally viewed as an aid to niche employment, in other words as processes of network inclusion. This article examines both processes of inclusion and exclusion in the social networks of Asian Indian migrants in and outside of ethnic economies. Evidence from the life histories of these migrants in New York and London allows us to see the role of social networks in producing cooperation and conflict within modes of economic inclusion and exclusion.
