Abstract
Purpose
The aim of this paper is to review and analyze the research literature on the health and safety issues of migrant workers in the construction industry from 2000 to 2022.
Design/methodology/approach
5 steps method is used to conduct a systematic review to achieve the objectives. After scanning two authoritative search engines “Web of Science” and “Scope”, 60 articles are selected from 225 publications for identification and review. These identified articles are classified by research fields, countries and time span.
Findings
The review finds that with the increasing influence of migrant construction workers, the number of publications on the health and safety of migrant workers has shown a rapid upward trend. Moreover, language barriers are the most dominant safety risk factors encountered by on-site migrant workers. This systematic literature review also summarizes the definition of migrant workers and solutions to reduce safety risk factors.
Originality/value
The research data on the health and safety issues and risk factors of migrant workers in the construction industry is still limited. This literature review summarizes the research trends and contributions of the literature in this field in the past 22 years and provides theoretical support for future research on the safety management of the migration construction field.

Abstract
The first Sustainable Development Goal (SDG), which is to be attained by the year 2030, is to ‘End poverty in all its forms everywhere’.1 However, the progress made in reducing poverty has been reversed due to the spread of the COVID-19 pandemic. The worsening poverty, inequality and vulnerability call for identifying the acuteness of the problem with the help of dimensions like the economic dependency ratio along with other sources like poverty line, access to social security, health care, basic services, food security and asset ownership and social networks at the village to name a few. The economic dependency ratio goes beyond the age dependency ratio and tries to capture the dependency better by incorporating the number of dependants and employed ones in the calculation. In this study, an attempt has been made to highlight the importance of the economic dependency ratio to measure vulnerability better in India. Unemployment data provided by the Centre for Monitoring Indian Economy (CMIE) has been utilised to understand the severity of dependency at the country level. Primary data has been collected with the help of the Proportionate Stratified Sampling method from 600 notified, non-notified slum households staying in the western part of India and in-depth interviews have been conducted with a few homeless families. Quantitative data has been analysed using SPSS and Stata software.
This study will be immensely useful as it aims to improvise the methodology to identify the poor and vulnerable. Better identification can take us a step closer to achieving SDG 1.

Abstract
Purpose
The purpose of this paper is to present a hybridized technique for analyzing the behavior of an industrial system stochastically utilizing vague, imprecise, and uncertain data. The press unit of a paper mill situated in a northern part of India, producing 200 tons of paper per day, has been considered to demonstrate the proposed approach. Sensitivity analysis of system's behavior has also been done.
Design/methodology/approach
In the proposed approach, two important tools namely traditional Lambda‐Tau technique and genetic algorithm have been hybridized to build genetic algorithms‐based Lambda‐Tau (GABLT) technique to analyze the behavior of complex repairable industrial systems stochastically up to a desired degree of accuracy. This technique has been demonstrated by computing six well‐known reliability indices used for behavior analysis of the considered system in more promising way.
Findings
The behavior analysis results computed by GABLT technique have reduced region of prediction in comparison of existing Lambda‐Tau technique region, i.e. uncertainties involved in the analysis are reduced. Thus, it may be a more useful analysis tool to assess the current system conditions and involved uncertainties. The paper suggested an approach to improve the system's performance.
Originality/value
The paper suggests a hybridized technique for analyzing the stochastic behavior of an industrial subsystem by computing six well‐known reliability indices in the form of fuzzy membership function.

Abstract
Purpose
Security is the major issue that motivates multiple scholars to discover security solutions apart from the advantages of wireless sensor networks (WSN) such as strong compatibility, flexible communication and low cost. However, there exist a few challenges, such as the complexity of choosing the expected cluster, communication overhead, routing selection and the energy level that affects the entire communication. The ultimate aim of the research is to secure data communication in WSN using prairie indica optimization.
Design/methodology/approach
Initially, the network simulator sets up clusters of sensor nodes. The simulator then selects the Cluster Head and optimizes routing using an advanced Prairie Indica Optimization algorithm to find the most efficient communication paths. Sensor nodes collect data, which is securely transmitted to the base station. By applying prairie indica optimization to WSNs, optimize key aspects of data communication, including secure routing and encryption, to protect sensitive information from potential threats.
Findings
The Prairie Indica Optimization, as proposed, achieves impressive results for networks comprising 50 nodes, with delay, energy and throughput values of 77.39 ms, 21.68 J and 22.59 bps. In the case of 100-node networks, the achieved values are 80.95 ms, 27.74 J and 22.03 bps, significantly surpassing the performance of current techniques. These outcomes underscore the substantial improvements brought about by the Prairie Indica Optimization in enhancing WSN data communication.
Originality/value
In this research, the Prairie Indica Optimization is designed to enhance the security of data communication within WSN.

This case study concerns self-managed teams (SMTs) and high-performing work stations.
Abstract
Subject area
This case study concerns self-managed teams (SMTs) and high-performing work stations.
Studylevel/applicability
This study is applicable to training, employee satisfaction and developing economy in the society at large.
Case overview
High-performance work systems (HPWS) are processes in which organizations utilize a fundamentally different approach for managing work in place of the traditional hierarchal approach. HPWS uses an approach that is fundamentally different from the traditional hierarchical or bureaucratic approach otherwise known as the control-oriented approach. The fundamental difference between control-oriented and involvement-oriented approach is in organizing and managing at the lowest level in an organization. The basic purpose of HPWS is to create an organization based on employee involvement, commitment and empowerment. In these kinds of highly involved organizations, employees demonstrate more responsibility and commitments because of high empowerment and have access to information/knowledge and awareness to perform at the highest level. In this case study, the authors make a complete study about the ten pillars of SMTs in Dr Reddy's Laboratories Private Ltd. and the situation of FTO-4 at the Yanam plant and FTO-7 at the Visakhapatnam plant post-implementation of the SMT concept. This paper attempts to demonstrate how SMTs differ from conventional teams, as well as how effectively they contribute to the organization objectives.
Expected learning outcomes
To understand HPWS and concept of SMT; to understand how the concepts of HPWS and SMT were implemented in Dr Reddy'S Laboratories in *FTO-4 AND *FTO-7; to understand the key difference between traditional hierarchical systems and SMTs; to find out how continuous process improvement has made SMT initiative an evolving one (from 2002 to 2011); to understand how involvement of different stakeholders has made SMT initiative a sustainable one; and to understand the importance of SMT in this twenty-first century as they lead to a better and brighter future for everyone.

Abstract
Purpose
The purpose of this paper is to formulate the reliability optimization problem in stochastic and interval domain and also to solve the same under different stochastic set up.
Design/methodology/approach
Stochastic programming technique has been used to convert the chance constraints into deterministic form and the corresponding problem is transformed to mixed-integer constrained optimization problem with interval objective. Then the reduced problem has been converted to unconstrained optimization problem with interval objective by Big-M penalty technique. The resulting problem has been solved by advanced real coded genetic algorithm with interval fitness, tournament selection, intermediate crossover and one-neighbourhood mutation.
Findings
A new optimization technique has been developed in stochastic domain and the concept of interval valued parameters has been integrated with the stochastic setup so as to increase the applicability of the resultant solution to the interval valued nonlinear optimization problems.
Practical implications
The concept of probability distribution with interval valued parameters has been introduced. This concept will motivate the researchers to carry out the research in this new direction.
Originality/value
The application of genetic algorithm is extended to solve the reliability optimization problem in stochastic and interval domain.

Abstract
Purpose
One of the existing and commonly used solar energy harvesting devices is the parabolic trough solar collector (PTSC). Because of their ability to operate in low and medium temperatures, parabolic trough concentrators are widely used in power generation plants and industrial process heating applications. Therefore, the investigation of how different operating conditions affect these devices’ overall efficiency has received a great deal of attention in the recent decade. This study aims to enhance the thermal performance of the PTSC and reduce the system cost.
Design/methodology/approach
In the novel configuration, a noncirculated nanofluid absorbs solar radiation through a glass wall. The base fluid was synthetic oil (5W30), and the nanoparticles used were copper oxide. The heat captured is immediately absorbed by the water circulating inside the copper tube immersed in the nanofluid. ANSYS FLUENT 15.0 was used for carrying out computational fluid dynamics simulations for two models of single and triple copper tubes. The experimental results obtained from a test rig constructed for this purpose were compared with the numerical outcomes of the single copper tube model.
Findings
The findings of the simulation demonstrated that performance was superior for the single copper tube model over the triple copper tube model. The numerical findings of the single copper tube model were compared with the experimental results. The numerical and experimental results differed from 3.17% to 5.6%. Investigations were carried out to study the effects of varying the volumetric flow rate of (20, 40, 60 and 80 L/h) and water inlet temperatures of (300, 315 and 330 K) on the effectiveness and performance of the newly developed model. Additionally, two nanofluid volume fractions of 0.05% and 0.075% were used for investigating their effect on the performance of the novel configuration. According to the findings, the highest thermal efficiency of 55.31% was recorded at 0.075% concentration and 80 L/h volume flow rate.
Originality/value
In this study, a novel direct absorption solar collector configuration using a noncirculated nanofluid was designed to enhance the thermal efficiency of PTSC. This new approach makes it possible to boost the thermal performance of the PTSC and lower the system’s cost.

Abstract
Purpose
This hypothetical case study aims to revisit the classical model given by Henri Fayol whereby he put forward a set of 14 principles to guide managers in decision-making across organizations. The case study showcases the dilemma in which the top manager of an automobile company finds himself when some of the very basic principles – on which the whole discipline of management is founded – are ignored. It will also serve as an aid for faculty members in B-Schools to teach students the significance of basic management principles postulated many years back which stand relevant even in contemporary times.
Design/methodology/approach
This case study is based on a hypothetical scenario in the corporate world. Different incidents in a fictitious automobile manufacturing firm are presented and the corresponding principles given by Henri Fayol are inferred.
Findings
This case study highlights that decision-making gets complicated if fundamental principles of management are not complied with. The decision taken during each and every situation which has been discussed in this case study is contrary to the correct course of action as propounded by Fayol. Modern-day managers must acknowledge the relevance and importance of these principles for achieving success in business.
Originality/value
This case study underscores that even in this volatile business environment where most of the management practices are technology-driven, we cannot disregard the most elementary rules of management. The managers working at different levels in the organizational hierarchy may be guided to make the right decisions in situations similar to the ones described.

Abstract
Purpose
Brief introduction on the importance and the need for plastic analysis methods were presented in the beginning section of this review. The plastic method for analysis was considered to be the more advanced method of analysis because of its ability to represent the true behaviour of the steel structures. Then in the following section, a literature analysis has been carried out on the previous investigations done on steel plates, steel beams and steel frames by other authors. The behaviour of them under different types of loading were presented and are under the investigation of innovative new analysis methods.
Design/methodology/approach
Structure member connections also have the potential for plastic failure. In this study, the authors have highlighted a few topics to be discussed. The three topics in this study are T-end plate connections to a square hollow section, semi-rigid connections and cold-formed steel storage racks with spine bracings using speed-lock connections. Connection is one of the important parts of a structure that ensures the integrity of the structure. Finally, in this technical paper, the authors introduce some topics related to seismic action. Application of the Theory of Plastic Mechanism Control in seismic design is studied in the beginning. At the end, its in-depth application for moment resisting frames-eccentrically braced frames dual systems is investigated.
Findings
When this study involves the design of a plastic structure, the design criteria must involve the ultimate load rather than the yield stress. As the steel behaves in the plastic range, it means the capacity of the steel has reached the ultimate load. Ultimate load design and load factor design are the methods in the range of plastic analysis. After the steel capacity has reached beyond the yield stress, it fulfills the requirement in this method. The plastic analysis method offers a consistent and logical approach to structural analysis. It provides an economical solution in terms of steel weight, as the sections designed using this method are smaller compared with elastic design methods.
Originality/value
The plastic method is the primary approach used in the analysis and design of statically indeterminate frame structures.
