Abstract

Purpose

This paper aims to review comprehensively the different voltage-boosting techniques and classifies according to their voltage gain, stress on the semiconductor devices, count of the total components and their prominent features. Hence, the focus is on non-isolated step-up converters. The converters categorized are analyzed according to their category with graphical representation.

Design/methodology/approach

Many converters have been reported in recent years in the literature to meet our power requirements from mill watts to megawatts. Fast growth in the generation of renewable energy in the past few years has promoted the selection of suitable converters that directly impact the behaviour of renewable energy systems. Step-up converters are a fast-emerging switching power converter in various power supply units. Researchers are more attracted to the derivation of novel topology with a high voltage gain, low voltage and current stress, high efficiency, low cost, etc.

Findings

A comparative study is done on critical metrics such as voltage gain, switch voltage stress and component count. Besides, the converters are also summarized based on their advantages and disadvantages. Furthermore, the areas that need to be explored in this field are identified and presented.

Originality/value

Types of analysis usually performed in dc converter and their needs with the areas need to be focused are not yet completely reviewed in most of the articles. This paper gives an eyesight on these topics. This paper will guide the researchers to derive and suggest a suitable topology for the chosen application. Moreover, it can be used as a handbook for studying the various topologies with their shortfalls, which will provide a way for researchers to focus.

Abstract

Purpose

The purpose of this research is to systematically scrutinize the influence of macroeconomic determinants on trade openness, through the lens of various trade theories, with a particular focus on the economies of the GIPSI countries – Greece, Ireland, Portugal, Spain and Italy.

Design/methodology/approach

This study investigates the macroeconomic factors influencing trade openness in the GIPSI economies from 1995 to 2020. Methods include stepwise regression (SR) for model selection, Pedroni panel cointegration test and panel regression results. The analysis uses advanced panel regressions, including FMOLS, Panel OLS and FEM. The long-term dynamics were tested using Pedroni cointegration, while Granger causality testing was used to examine the causal direction between the trade openness ratio and trade determinant.

Findings

The results show both long-term and short-term relationships between trade openness and (1) foreign direct investment, (2) labor force participation rate, (3) trade reserves and (4) trade balance. The researchers also detected unidirectional and bidirectional causality relationships between trade openness and these four factors. The study also revealed that trade reserves (TR) emerge as the most influential determinant of trade openness, and per capita income does not exhibit economic significance concerning the trade openness of GIPSI economies.

Research limitations/implications

This research is conducted within the context of the GIPSI nations (Greece, Ireland, Portugal, Spain and Italy). As such, the outcomes may not be universally applicable to other economic systems due to the distinct institutional settings and governance structures across different economic groups. Future investigations may explore the relationship between trade openness and its determinants by incorporating different variables.

Originality/value

To the best of the authors' knowledge, this is the first study investigating the theory that suggested trade drivers drive the trade openness of GIPSI countries context. By focusing on GIPSI countries, the study offers a unique perspective on the dynamics of trade openness in economies that have experienced financial crises and stringent austerity measures.

Abstract

Purpose

This study aims to understand the impact of negative supervisor gossip on job performance among South Indian hotel employees. The focus is not just on the direct influence, but also on the mediating role of feedback-seeking behaviour (FSB) and the moderating effects of the agreeableness trait.

Design/methodology/approach

Through purposive sampling, data was garnered from South Indian hotel employees. Comprehensive analyses were performed using partial least squares structural equation modelling.

Findings

The analysis shows that FSB plays a mediating role in the positive relationship between negative supervisor gossip and job performance. In addition, the influence of gossip on FSB and subsequent job performance was more pronounced for employees with high agreeableness.

Research limitations/implications

This research underscores the complex interplay between negative supervisor gossip and job performance, revealing that such gossip can catalyze FSB process in employees. It suggests that under certain conditions, negative gossip can be transformed into a constructive force that enhances job performance, challenging traditional perceptions of gossip in the workplace.

Practical implications

The findings underscore the importance of understanding the effects of workplace dynamics, like supervisor gossip, on employee behaviour and performance. Recognizing the influence of individual personality traits, such as agreeableness, can guide management strategies for fostering a productive work environment.

Originality/value

This research sheds light on the intricate interplay between negative supervisor gossip, FSB and agreeableness, offering a novel perspective on their combined impact on job performance. It not only enriches the existing literature on workplace communication but also broadens the understanding of the role of personality traits in shaping employee responses and outcomes.

Abstract

Purpose

Green HRM practices in the hospitality sector are now receiving growing interest. However, the extent to which these practices contribute towards employee non-green workplace outcomes remains largely unknown. This study explores the relationships among green HRM practices, happiness at work, employee resilience, and feedback-seeking behaviour.

Design/methodology/approach

The study employs two-wave data from a sample of 306 five-star hotel employees in India. Using partial least square-structural equation modelling, the relationships are tested.

Findings

The study’s results demonstrate that green HRM practices positively impact happiness at work, employee resilience, and feedback-seeking behaviour. Additionally, the relationship between green HRM practices and feedback-seeking behaviour and employee resilience is mediated by happiness at work.

Research limitations/implications

Drawing on the Job Demands-Resources Theory, Social Exchange Theory, and Broaden and Build theory, this paper proposes that green HRM practices can contribute to happiness at work, employee resilience, and feedback-seeking behaviour.

Practical implications

To establish a positive connection between green HRM practices and employee outcomes, organizations must recognize the vital role played by happiness at work as a mediator. This means that organizations must implement green HRM practices and ensure their positive impact on employee happiness at work.

Originality/value

The originality of this research lies in its holistic approach to green HRM outcomes, suggesting that the benefits of these practices extend beyond environmental impacts to influence the psychological and behavioural dimensions of employees.

Abstract

Purpose

The study aims to focus on data envelopment analysis for assessing the microfinance institutions (MFIs) efficiency over the footings of its undesirable output, i.e. non-performing loans (NPLs). The attention is not only to evaluate the efficiency but also to identify the variable wise inefficiencies incorporating the quality of the portfolio.

Design/methodology/approach

The paper assessed MFI efficiency using three different methods of treatment of undesirable output to portray the significant difference. It also has used an advanced methodological model, i.e. weighted Russell directional distance model (WRDDM), under the non-radial assumption that allowed us to find the variable-wise inefficiency contribution. The study also investigated the efficiency differences concerning ownership, including all sizes of MFIs.

Findings

The study findings evidence the fall in efficiency score as NPL integrated, and it is found to be statistically significant. In the context of inefficiency assessment, among all input and output variables, total employees and operating expenses, portfolio quality inefficiencies are the leading causes of MFI inefficiencies. Undesirable output inefficiency accounts for almost one-third part of the total inefficiencies and remaining due to input inefficiencies. It is significant to draw attention that there is no improvement in undesirable output inefficiency. By contrast, input inefficiencies retained gains for two years and gradually showed a decreasing trend throughout 2015–2017.

Research limitations/implications

The authors have used balanced panel data of 72 Indian MFIs for five years' period from 2013–2017 whose complete data were available in the Microfinance Information Exchange.

Practical implications

The paper has focused on identifying the inefficiencies that are needed to be focused on to attain efficiency. It could provide vital information to the managers, policymakers in identifying the causes of inefficiencies, which is crucial to improve for long-term sustainability. It will be a roadmap for benchmarking, strategy building and policy-making processes.

Social implications

The findings of the study help in finding the benchmarking information for the inefficient decision-making units to identify the target units that need particular attention to focus. These practices could give a positive outcome, not only for institutions but also for the MFI clients.

Originality/value

The study provides an insight in to variable-wise inefficiency measurement using advanced model WRDDM in Indian context MFIs.

Abstract

Study level/applicability

The case focuses on Thivra Info Solutions Pvt Ltd, an entrepreneurial organization incubated by Prasannan (she/her) in 2017. The organization started with a mission to provide technology-based learning solutions for children diagnosed with autism spectrum disorder (ASD). Thivra Info Solutions Pvt Ltd had developed multiple offerings, including gamified learning, targeted to ASD and general ed-tech users. The firm also launched “Dwani,” the communicative-based learning app for ASD children. The initial feedback by users, parents and teachers had been encouraging. Prasannan was exploring avenues to scale the business when the Covid-19 pandemic affected all the operations.The case presents the multiple dilemmas entrepreneurial firms face in managing resources, finances, growth and product and customer focus. Students are encouraged to debate the organization strategy, product and consumer target segments and solutions to scale the business while managing frugal resources.

Subject area

This case study can be used in entrepreneurship, leadership, crisis management, business development, organizational behavior and technology.

Case overview

The case study describes the navigation of Thivra from a Generic Gamified App to its niche of catering for ASD students. The case presents the challenges presented to leadership to manage the crisis and try to grow their entrepreneurial venture. This case has been designed for use in business-to-consumer marketing or entrepreneurship, gender entrepreneurship, ed-tech-based startups, in MBA, executive MBA or executive education programs in the field. The case is suitable for those doing business in Asia, for post-graduate and under-graduate students studying business innovation, entrepreneurship, strategy and marketing. It is also appropriate for courses on gender entrepreneurship; women and crisis management; and product management. The case aims at facilitating classroom discussion on the extension of Indian-based ed-tech startups to ASD children.

Expected learning outcomes

Students will also be able to explore the following issues: to study the role played by a business model that withstands the competition over a long period and adopting sustainability; to describe the concept and implications of paradoxical leadership, thereby drawing its impact on business decisions; to analyze how a leader acts in terms of crisis from a startup point of view; to draw the phases and constraints of the enterprise development and compare and contrast it based on gender; to demonstrate the value to different constituents (ASD students, parents, teachers and ASD counselors) by understanding their differentiated needs and developing powerful value propositions for each. Articulating and demonstrating this value is key to gaining the buy-in of the various decision-making units; to understand how, having gained traction in one market segment (in this case, tractions with parents of ASD children), a company can develop new market segments; to study the issues and problems faced by startups in developing economies, especially the tech-based ones; and to understand the application of gamification on education and communication for ASD children.

Abstract

Purpose

This exploratory study aims to explore the perceptions and experience of women doctors on working with each other and draw attention to their ‘voice’ on this issue. The equivocal and limited nature of relevant literature piqued our curiosity on how women perceive working with each other in work settings, particularly within the medical profession.

Design/methodology/approach

Twelve women doctors within Australian public hospitals were interviewed through semi-structured informal interviews to “voice” their experiences and views on the comforts and discomforts of working with other women doctors. Their responses were compared to literature to determine similarities and uniqueness of their experiences to women in other settings.

Findings

Insights from the respondent’s perceptions and experiences highlight several constructive and negative aspects of working alongside women doctors. Social and psychological constructs of being a “woman” and being a “woman doctor” as well as systemic/cultural issues of the medical fraternity formed how the women in this series of interviews perceived and related to the women doctors they worked with.

Research limitations/implications

This exploratory provides initial insights into the experiences of women doctors on working with each other. Many themes identified have been explored in other settings. Hospital as a workplace, presents many similar work dynamics when considering the work interactions of women in other settings. This study should be used to drive more rigorous enquiry and a larger sample size.

Practical implications

The working relationships women build with each other influence individual careers and organizational outcomes. Understanding the dynamics that improve and hinder the development of constructive work relationships between women can strengthen women-focused managerial and organizational policies and practices.

Originality/value

The consolidation of literature coupled with the exploratory insights of this research contributes to a limited depth of existing literature not only in the medical profession, but in other industries and settings as well.

Abstract

Purpose: This chapter explores the two major schemes applicable to skill development in India: Skill Acquisition and Knowledge Awareness for Livelihood Promotion (SANKALP) and Pradhan Mantri Kaushal Vikas Yojana (PMKVY).

Need for the Study: The primary objective of this research is to check the role of these schemes in enhancing the skills of socio-economically stressed community members for their livelihoods. The secondary aim is to analyse the outcomes of these schemes through a qualitative inquiry.

Methodology: A survey was conducted, and the data was collected from trainees of the skill development programmes. Based on the responses, a qualitative content analysis was performed, which showed that most trainees have the thirst and urge to enhance their life skills for a minimalistic livelihood.

Findings: The study concluded that though there are many schemes, only PMKVY is active. They focus on more than just youth communities. Instead, they consider individuals in different age categories.

Practical Implications: The Government of India (GOI) is progressing towards a healthy economy to compete with other countries. For this mission to be achieved, skill and labour development is paramount. Appropriate training must be provided and administrated through government schemes.

Abstract

Purpose

Web services composition engineering (WSCE) is a big challenge because of the increasing complexity, openness and extensibility of services based on the information system (IS). In the absence of an adequate framework for IS engineering, the authors assume that the overall problem is consequently no longer easy to resolve. This paper aims to explore some of the issues underlying WSCE through a framework, which is built based on the state of the art. The proposed framework is structured around five views that mainly highlight aspects of personalization and security concerns. The main objectives of this framework are: to help understand and clarify the basics of the WSCE domain; to evaluate web services composition (WSC) methods; to analyze and compare existing personalization, secure methods and identify new research axes; and to identify the main criteria of the ongoing approach for the design of a secure IS based on personalized WSC.

Design/methodology/approach

This work develops a framework that is used as an analytical study to compare the existing WSCE methods and come up with research issues. Then, the proposed framework is considered as an abstract model for the new WSCE approach.

Findings

A set of criteria that the proposed framework should consider when developing a new approach to a secure IS based on personalized WSs composition.

Research limitations/implications

The paper has theoretical implications as the personalization and security issues provide a research roadmap toward the realization of an approach for the design of a secure IS based on personalized WSs composition.

Practical implications

As proof, the authors are interested in a web services repository of a real mall. To do this, the authors deployed the application in a cloud environment and observed the results of personalization and security concepts in WSCE.

Originality/value

None of the existing comparison frameworks has raised both personalization and security issues in WSs composition, while personalization and security must be present in the whole composition process.

Abstract

Purpose

The main purpose of the paper is timing analysis of mixed critical applications on the multicore system to identify an efficient task scheduling mechanism to achieve three main objectives improving schedulability, achieving reliability and minimizing the number of cores used. The rise in transient faults in embedded systems due to the use of low-cost processors has led to the use of fault-tolerant scheduling and mapping techniques.

Design/methodology/approach

The paper opted for a simulation-based study. The simulation of mixed critical applications, like air traffic control systems and synthetic workloads, is carried out using a litmus-real time testbed on an Ubuntu machine. The heuristic algorithms for task allocation based on utilization factors and task criticalities are proposed for partitioned approaches with multiple objectives.

Findings

Both partitioned earliest deadline first (EDF) with the utilization-based heuristic and EDF-virtual deadline (VD) with a criticality-based heuristic for allocation works well, as it schedules the air traffic system with a 98% success ratio (SR) using only three processor cores with transient faults being handled by the active backup of the tasks. With synthetic task loads, the proposed criticality-based heuristic works well with EDF-VD, as the SR is 94%. The validation of the proposed heuristic is done with a global and partitioned approach of scheduling, considering active backups to make the system reliable. There is an improvement in SR by 11% as compared to the global approach and a 17% improvement in comparison with the partitioned fixed-priority approach with only three processor cores being used.

Research limitations/implications

The simulations of mixed critical tasks are carried out on a real-time kernel based on Linux and are generalizable in Linux-based environments.

Practical implications

The rise in transient faults in embedded systems due to the use of low-cost processors has led to the use of fault-tolerant scheduling and mapping techniques.

Originality/value

This paper fulfills an identified need to have multi-objective task scheduling in a mixed critical system. The timing analysis helps to identify performance risks and assess alternative architectures used to achieve reliability in terms of transient faults.
