Abstract

Risk factors for population relocation as a result of severe catastrophes are increasing on a global scale. The frequency of catastrophic weather events is rising, infrastructure is getting older, the population is expanding, and urbanization is increasing. This study explores the influencing factors of livelihood, vulnerability, and livelihood resilience of climate-induced displaced people in developing countries, particularly in South Asia. A mixed-method approach comprising a systematic review and a narrative review has been applied in this study. A systematic review guided by PRISMA has been used to identify the relevant documents and the extracted information has been described through a narrative review approach. This study reveals that climate-induced displaced people are generally vulnerable to maintaining their livelihood, but there are a few exceptional cases where displaced people could diversify their livelihood strategies. The major influencing factors of their livelihoods are riverbank erosion, loss of assets and properties, food insecurity, seasonal hunger, low access to finance, and low job opportunity. This study argues that climate-displaced people have a long struggle to enhance their livelihood resilience, but it is a challenging task for them, particularly at the household level. The major influencing indicators under adaptive, absorptive, and transformative capacities of livelihood resilience are income and food access, agricultural and non-agricultural assets, sensitivity, climate variability and hazards, basic services, social safety nets, and institutional participation. Appropriate governance in the structural and non-structural transformation of livelihood capitals can enhance the livelihood resilience of climate-induced displaced households. In the case of Bangladesh, the coastal and Riverine Island communities are the key victims of climate-induced hazards, so they migrated frequently to reduce their vulnerability and enhance livelihood resilience. The study recommends ensuring transparency and accountability, proper coordination among stakeholders for promoting the resettlement, disaster-resilient housing and infrastructure, and Khas land (government-owned land) to the displaced people can enhance their livelihood resilience.

Abstract

Purpose

Software defect prediction (SDP) is a critical aspect of software quality assurance, aiming to identify and manage potential defects in software systems. In this paper, we have proposed a novel hybrid approach that combines Grey Wolf Optimization with Feature Selection (GWOFS) and multilayer perceptron (MLP) for SDP. The GWOFS-MLP hybrid model is designed to optimize feature selection, ultimately enhancing the accuracy and efficiency of SDP. Grey Wolf Optimization, inspired by the social hierarchy and hunting behavior of grey wolves, is employed to select a subset of relevant features from an extensive pool of potential predictors. This study investigates the key challenges that traditional SDP approaches encounter and proposes promising solutions to overcome time complexity and the curse of the dimensionality reduction problem.

Design/methodology/approach

The integration of GWOFS and MLP results in a robust hybrid model that can adapt to diverse software datasets. This feature selection process harnesses the cooperative hunting behavior of wolves, allowing for the exploration of critical feature combinations. The selected features are then fed into an MLP, a powerful artificial neural network (ANN) known for its capability to learn intricate patterns within software metrics. MLP serves as the predictive engine, utilizing the curated feature set to model and classify software defects accurately.

Findings

The performance evaluation of the GWOFS-MLP hybrid model on a real-world software defect dataset demonstrates its effectiveness. The model achieves a remarkable training accuracy of 97.69% and a testing accuracy of 97.99%. Additionally, the receiver operating characteristic area under the curve (ROC-AUC) score of 0.89 highlights the model’s ability to discriminate between defective and defect-free software components.

Originality/value

Experimental implementations using machine learning-based techniques with feature reduction are conducted to validate the proposed solutions. The goal is to enhance SDP’s accuracy, relevance and efficiency, ultimately improving software quality assurance processes. The confusion matrix further illustrates the model’s performance, with only a small number of false positives and false negatives.

Abstract

Purpose

This study develops and tests a comprehensive model that examines whether dimensions of supervisors’ job demands and resources influence their work motivation through their job strain levels while managing disability accommodation (DA).

Design/methodology/approach

The proposed model leverages the assumptions of established job demand and resources theories, including demand-ability fit, job demand-control, job demand-control-support, and effort-reward balance models. Then, we tested with the quantitative data from 335 British, Canadian, American, Australian, Dutch, and German supervisors with recent DA experience.

Findings

This study found support for the proposed model. Job control and social support directly affected work motivation, while job strain did not mediate the relationship between job control and social support and work motivation. The results suggest that employers looking to improve the likelihood of DA success should focus on providing adequate job control, social support, and rewards to supervisors responsible for accommodating employees with disabilities.

Practical implications

This research enhances our understanding of how additional DA responsibilities impact supervisors and aids in the development of effective DA management policies and interventions, providing robust support for practitioners.

Originality/value

This study contributes to extending the DA literature by testing the applicability of different theoretical models to explain the effect of the additional DA responsibility on supervisors’ job demand, strain, and motivation levels and identify the resources to mitigate them.

Abstract

While rapid increase in demand for foods but limited availability of croplands has forced to adopt input-intensive farming practices to increase yield, there are serious long-term ecological implications including degradation of biodiversity. It is increasingly recognised that ensuring agricultural sustainability under the changing climatic conditions requires a change in the production system along with necessary policies and institutional arrangements. In this context, this chapter examines if climate-smart agriculture (CSA) can facilitate adaptation and mitigation practices by improving resource utilisation efficiency in India. Such an attempt has special significance as the existing studies have very limited discussions on three main aspects, viz., resource productivity, adaptation practices and mitigation strategies in a comprehensive manner. Based on insights from the existing studies, this chapter points out that CSA can potentially make significant contribution to enhancing resource productivity, adaptation practices, mitigation strategies and food security, especially among the land-constrained farmers who are highly prone to environmental shocks. In this connection, staggered trench irrigation structure has facilitated rainwater harvesting, local irrigation and livelihood generation in West Bengal. However, it is necessary to revisit the existing approaches to promotion of CSA and dissemination of information on the design of local adaptation strategies. This chapter also proposes a change in the food system from climate-sensitive to CSA through integration of technologies, institutions and policies.

Abstract

A “state-driven” approach suggests that colonists use census categories to rule. However, a “society-driven” approach suggests that this state-driven perspective confers too much power upon states. A third approach views census-taking and official categorization as a product of state–society interaction that depends upon: (a) the population's lay categories, (b) information intellectuals' ability to take up and transform these lay categories, and (c) the balance of power between social and state actors. We evaluate the above positions by analyzing official records, key texts, travelogues, and statistical memoirs from three key periods in India: Indus Valley civilization through classical Gupta rule (ca. 3300 BCE–700 CE), the “medieval” period (ca. 700–1700 CE), and East India Company (EIC) rule (1757–1857 CE), using historical narrative. We show that information gathering early in the first period was society driven; however, over time, a strong interactive pattern emerged. Scribes (information intellectuals) increased their social status and power (thus, shifting the balance of power) by drawing on caste categories (lay categories) and incorporating them into official information gathering. This intensification of interactive information gathering allowed the Mughals, the EIC, and finally British direct rule officials to collect large quantities of information. Our evidence thus suggests that the intensification of state–society interactions over time laid the groundwork for the success of the direct rule British censuses. It also suggests that any transformative effect of these censuses lay in this interactive pattern, not in the strength of the British colonial state.

Abstract

Purpose

The way theory is used and developed in qualitative research has been a controversial issue, since theory provides a filter through which qualitative data are interpreted, and the “story” is told. This paper aims to present a study of the Fiji Development Bank (FDB) that demonstrates the impact a different theoretical lens has on the selection and interpretation of events, the story that is produced, and the unique view of the role of accounting within its social context.

Design/methodology/approach

This paper examines two possible interpretations of the FDB's role under the magnifying glass of Llewellyn's five levels of theorising and the world‐view of the researchers.

Findings

An analysis of the use of theory and the level of theorising brings to light the difference theory makes to the story that unfolds. On the one hand, accounting is seen as a tool of a repressive system, an example of the outworking of a grand theory, and on the other hand, while no grand theory is overtly employed, the FDB is viewed as a unifying catalyst for the coexistence of two apparently contradictory social institutions.

Research limitations/implications

This interpretation of the role and effect of theory in qualitative research is unique and contestable, but forms part of the debate that is a necessary part of the advancement of academic knowledge.

Originality/value

Llewellyn's claim that higher level theory develops from lower levels of theorising is challenged, and the assertion is made that grand theory is employed not as the culmination of a theoretical hierarchy, but because of the presence of a preconceived world‐view which informs the choice of theory at every level.

Abstract

The COVID-19 pandemic has had a significant impact on higher education (HE) across the globe, including in Bangladesh. The Bangladeshi HE system is going through an abrupt transition and transformation to cope with the crisis. This chapter is based on data collected from teachers and students of Bangladeshi public and private HE institutions regarding teaching and learning during the COVID-19 lockdown. In Bangladesh, some universities switched to online distance teaching and learning quickly during this period, and others lagged behind in this regard. Teachers and students from both groups of public and private universities participated in the study, including those who attended online teaching and learning activities and those who did not participate. This chapter highlights both teachers’ and students’ perspectives regarding students’ future preparedness for participating fully in the changing landscape of HE, especially technology-enhanced teaching and learning. Understanding these perspectives of teachers and students is important to address the digital divide and social justice issues in the policy and practice. Within the HE sector in Bangladesh, it is especially vital while transforming its education system and adapting emerging technologies to address the challenges of education in future emergencies.

Abstract

Purpose

This study examines how resource dependency affects municipal budgetary process; specifically, it investigates how politically aligned resource sharing between different levels of government along with clientelism interferes with the budgetary process of municipal organizations in developing countries.

Design/methodology/approach

The paper adopts a qualitative approach to study two municipal organizations in Bangladesh. The qualitative data are collected from semi-structured interviews with key organizational members. Besides, the study also relies on various publicly available documents and the Local Government Acts to complement the interview data.

Findings

The findings of the study divulge dependence on partisan aligned nonprogrammable government funds poses significant problems for municipal organizations in carrying out their budgetary process. Clientelism and informal negotiations of incumbent political leaders are found to play a vital role in such resource sharing decisions. The consequent uncertainties in getting funds have the potentials of interrupting the budgetary process at the organizational level. In some cases, budgets do not appear to be useful as a management tool for guiding organizational activities.

Research limitations/implications

Like other qualitative studies, the results of these case studies are not generalizable because their interpretations are highly dependent on the context of the research sites.

Practical implications

Despite the limitation of a case study research, the results of this study are useful to deepen our understanding of how uncertainty in resource sharing creates clientele behavior and interferes with the organizational budget. Such an understanding helps practitioners and policymakers devise a sound resource sharing mechanism for effective delivery of municipal services on a sustainable basis.

Originality/value

This study provides insight into how precarious central government transfers and clientelism interfere with local governments' budgetary process.

Abstract

Purpose

Employee knowledge is an essential contributor to managing supply chain ambiguities and supply improvement. The current research examined green technology (GT) implementation and knowledge management (KM) processes toward knowledge worker supply performance (KWSP). The present study postulates that GT implementation's positive impacts on the KM process and KM process lead to improved KWSP based on employee knowledge contribution.

Design/methodology/approach

To accomplish the research objective, the data were taken from those production houses that are utilizing GT. A total of 400 questionnaires were distributed in Zhengzhou city, and feedback was received (343). The feedback data were studied through partial least squares-structural equation modelling (PLS-SEM) and fuzzy set qualitative comparative analysis (fsQCA). fsQCA is used to analyze improving the multiple configurational paths of KWSP.

Findings

The study revealed that GT implementation is positively associated with the KM process, and KM processes substantially influence the improvement of KWSP. The consequence of fsQCA demonstrated that various combinations improve supply chain performance. The study combines certain dimensions of GT implementation with the KM process, revealing that supply chain performance improved based on knowledge sharing in manufacturing firms.

Research limitations/implications

This study guides decision-makers and academics on using the knowledge process associated with GT to improve supply chain performance. Moreover, future researchers should use information technology in supply houses and compare the result with the literature to generalize the results better.

Originality/value

The asymmetric technique assists in differentiating the connections that are not directly investigated by the traditional symmetric method. The study covers and identifies various approaches that can be used in manufacturing firms to improve the supply chain process and employee satisfaction. The study combines the two techniques to understand supply performance based on knowledge sharing in manufacturing firms.

Abstract

Purpose

The purpose of this paper is to present an analytical approximate technique to solve nonlinear conservative oscillator based on the He’s energy balance method (improved version recently presented by Khan and Mirzabeigy). The method is illustrated by solving double well Duffing oscillator.

Design/methodology/approach

The Duffing equation with a double-well potential (with a negative linear stiffness) is an important model of a mass particle moving in a symmetric double well potential. This form of the equation also appears in the transverse vibrations of a beam when the transverse and longitudinal deflections are coupled (Thompsen, 2003).

Findings

The approximate solutions obtained by the present technique have good agreement with the numerical solution and also provide better results than other existing methods.

Originality/value

The results are more accurate than those obtained by other existing methods. The relative errors obtained by the present paper are less than those obtained by other existing methods. Therefore, the present technique is very effective and convenient for solving nonlinear conservative oscillator.
