Abstract

Purpose

Design, fabricate and evaluate all-solid-state wearable sensor systems that can monitor ion concentrations in human sweat to provide real time health analysis and disease diagnosis capabilities.

Design/methodology/approach

A human health monitoring system includes disposable customized flexible electrode array and a compact signal transmission-processing electronic unit.

Findings

Patterned rGO (reduced-graphene oxide) layers can replace traditional metal electrodes for the fabrication of free-standing all solid film sensors to provide improved flexibility, sensitivity, selectivity, and stability in ion concentration monitoring. Electrochemical measurements show the open circuit potential of current selective electrodes exhibit near Nernst responses versus Na+ and K+ ion concentration in sweat. These signals show great stability during a typical measurement period of 3 weeks. Sensor performances evaluated through real time measurements on human subjects show strong correlations between subject activity and sweating levels, confirming high degree of robustness, sensitivity, reliability and practicality of current sensor systems.

Originality/value

In improving flexibility, stability and interfacial coherency of chemical sensor arrays, rGO films have been the developed as a high-performance alternative to conventional electrode with significant cost and processing complexity reduction. rGO supported solid state electrode arrays have been found to have linear potential response versus ion concentration, suitable for electrochemical sensing applications. Current sweat sensor system has a high degree of integration, including electrode arrays, signal processing circuits, and data visualization interfaces.

Abstract

Purpose

This paper aims to establish a photoacoustic detection system for SO2 using UV-LED and testify its feasibility for sensitive measurement. The work in this paper can avoid potential crossover interference in infrared (IR) range and also balance the capability and cost of feasible excitation for photoacoustic detection system.

Design/methodology/approach

In this experimental work, a cantilever-enhanced–based photoacoustic SO2 detection system using an ultraviolet (UV) LED light source with a light power of 4 mW as the excitation was established.

Findings

A feasible photoacoustic detection system for SO2 using UV-LED was established. Experimental results demonstrate that the detection limit of the system can reach the level of 0.667 ppm, which can serve as a reference for the application of PAS in insulation fault diagnosis.

Originality/value

This work investigated the potential of using ultraviolet photoacoustic spectroscopy to detect trace SO2, which provided an ideal replacement of infrared-laser-based detection system. In this paper, a photoacoustic detection system using LED with a low light power was established. Low light power requirement can expand the options of light sources accordingly. In this paper, the absorption characteristics of SO2 in the presented detection system and ultraviolet range were studied. And the detection limit of the presented system was given. Both of which can provide reference to SO2 detection in ambient SF6.

Abstract

Purpose

The purpose of this paper is to offer a collection of articles that explore some of the many innovative approaches to qualitative inquiry and to challenge HRD scholars and practitioners to consider using innovative approaches in their work. In doing so, qualitative research in HRD can better capture and honour voices, experiences and meaning making of individuals, teams, organizations and communities.

Design/methodology/approach

Using Lê and Schmid’s (2022) definition of innovation in qualitative research, the authors selected four innovative approaches to qualitative research that have the potential to enhance HRD research and practice: use of multiple-case study designs in case study research in HRD, a new take on critical incident technique, a narrative approach of testimonio and a visual approach of participant photography.

Findings

Innovative approaches to qualitative research in this special issue include a review of case study research in HRD by Tkachenko et al., a new take on the familiar critical incident technique of Watkins et al., a narrative approach to testimonio by Salcedo et al. and a visual approach to participant photography by Hurtienne et al. The last article, by Grenier et al., addresses the implications of these articles to the field of HRD and points to additional directions for innovative qualitative approaches that can help to understand and create more inclusive, democratic and just organizations.

Research limitations/implications

The articles in this special issue are intended to spark a dialogue about the meaning of innovation in qualitative research in HRD. It also can serve as an impetus for considering how innovative approaches to qualitative research can better tackle questions that come from the new normal of the workplace, society and diverse contexts.

Practical implications

This special issue will give HRD scholars and practitioners a realistic, practical view on how innovation in qualitative research can help in exploring specific problems in the workplace. The articles will offer a glimpse into how specific social complex issues can be explored and addressed through innovative approaches, new and tried/modified, to qualitative inquiry.

Originality/value

Four articles introduce new and tried/modified qualitative methods, and their value is in prompting HRD scholars and practitioners to consider some of the innovative approaches in exploring, understanding and transforming the workplace. The final article is a review of more innovative qualitative approaches for HRD scholars and practitioners to understand complex organizational phenomena and promote positive and inclusive change accordingly.

Abstract

The aim of the study is to determine the nature and specificity of methodological approaches to management decision making in modern business systems. Management decisions are among the creative operations in the technology of management work. The methodology of decision making is of great applied importance and inevitably increases with the complexity of economic situations and management tasks. It is argued that on the one hand, decision making is a logical thinking activity and is implemented by senior staff and, on the other hand, is a management procedure and, therefore, should have a deep methodological study and be carefully organized and regulated by legislative and regulatory framework. It is proposed to consider approaches to management decision making as a set of basic methods of obtaining new knowledge, methods, and tools for solving problems of achieving the best result on the basis of in-depth study and compliance with the principles of organization of work in the chosen direction. The variety of approaches to management decision making reflects the different aspects of management processes taking place at the state and industry level, in the management of a particular business system. The practice of developing effective management solutions requires knowledge of universal and special approaches to the management of modern business systems and is a necessary competence of the management of a modern company.

Abstract

For nearly two decades, accounting educators have debated whether to continue with a preparer approach, or adopt a user perspective, or a blended model in the introductory financial accounting course. We examine the extent to which accounting programs have chosen to employ each approach, the factors that influenced their selection, as well as the relative importance of each factor. We also explore institutional and course characteristics associated with the choice of instructional method.

Our results indicate that one-third of programs employ the user perspective, and one-fifth the traditional preparer approach, while nearly half use a blend of the two. Programs using the preparer approach tend to focus on the accounting major (e.g., performance and career goals). In contrast, user approach institutions appear to emphasize performance issues and career paths of non-accounting majors.

This study aims to investigate the growing use of financial metrics (such as return on investment [ROI]) to measure performance and evaluate human capital (HC) investments.

Abstract

Purpose

This study aims to investigate the growing use of financial metrics (such as return on investment [ROI]) to measure performance and evaluate human capital (HC) investments.

Design/methodology/approach

The research employed an embedded case study approach, examining how one ROI approach was applied to evaluating HC investments, across three sectors (corporate, public health and international development).

Findings

Three major findings emerged in this study: First, interpretations of ROI can lead to ambiguity during implementation. ROI is interpreted trichotomously – metaphorically, as a desire for value; literally, as a metric; and procedurally, as a method for planning and evaluating HC investments. Second, understanding, measuring and tracking the domains of people performance (cognitive, affective and psychomotor) is vital to evaluating the impact of HC investments because this is where the change in behavior occurs. Third, although the logic model measures the change in process following an intervention (input-activity-output-outcome-impact), other approaches measure the change in behavior of people in the intervention (people performance).

Practical implications

These findings provide clarity for practitioners about challenges when applying ROI.

Originality/value

This is the first study to explore how the ROI financial metric is applied in a new domain by first examining its interpretation. It elucidates the use of ROI in practice, as well as the different purposes of key ROI approaches.

Abstract

Purpose

This study aims to review the approaches used in the analysis of rental income of residential property in Abuja, Nigeria, to strengthen the existing investment performance approaches initially relied upon by property investors towards having a better and reliable performance evaluation for property investment decision-making.

Design/methodology/approach

With the adoption of combined methodological approaches, quantitative data on rental history (2006–2016) were collected on the randomly selected residential investment properties (block of flats) available in the portfolio of estate surveying firms in the different locations/sub-markets of the study area. Data collected were analysed with the frequency mean and growth rate.

Findings

All the methodological approaches adopted for analysis displayed varying performance results. No particular sub-market maintains the same ranking position in any of the approaches. The developmental phases previously used as an indication of yield in the study area do not correspond with the status of rental income of sub-markets. Yield has been observed to be a mere attraction to property investment; it does not translate to income growth. Mean income (though a good indicator of changes in rental income) is not a reliable indicator of growth in income, and growth in the rate of income omitted the changes in rental income during the holding period.

Research limitations/implications

The study was restricted to historical rental income data on a block of flat-type residential property, and it does not include capital value analysis or inquire into the factors responsible for variation in rental income during the study period. The outcome of this study is only applicable to a block of 4 number three-bedroom flats residential property type.

Practical implications

Multiple simple methods of analysing rental income performance should be preferred to the single complex method. This will simplify investors’ rental income characteristics of investment towards a better understanding of rental property investment analysis. That rental value appreciates with time does not translate to an increase in the actual rental income of residential investment property.

Social implications

Through these performance approaches, ranking of the sampled properties in the study area sub-markets will enhance investors’ traditional diversification planning across the study area for an enhanced combination that can achieve latent profitability. The attention of investors is hereby called to these multiple approaches to enable them to merge their investment objectives with any or a combination of these approaches towards making rational investment decisions.

Originality/value

This seems to be the first advocacy for methodological paradigm shift applicable to direct residential property investment performance in Nigeria, using transaction rather than appraisal data.

Abstract

Purpose

This paper aims to analyze the benefits of the blockchain to the circular economy (CE), which is composed of both closed-loop supply chain (CLSC) systems and reverse omnichannel solutions. By ensuring transparency, traceability, visibility and security, the blockchain allows firms to acquire operational capabilities through a CLSC and service capabilities through a reverse omnichannel, which can boost business performance considerably. The related network of relationships can be reinforced by establishing incentives, which entail both smart contracts in the blockchain and active return approaches in CE.

Design/methodology/approach

After identifying the boundaries of the theoretical framework, several research hypotheses are developed according to the literature review and emerging gaps. These gaps link to the impact of the blockchain on CE systems (CLSC and reverse omnichannel), as well as the influence on business performance. The hypotheses are then tested using structural equation modeling and adopting a partial least squares-path modeling technique on a dataset composed of 157 firms. Finally, multigroup analysis is used to test the impact of incentives on the research hypotheses.

Findings

The blockchain facilitates a more efficient CE system, although reverse omnichannel solutions seldom bring any benefits to performance. The shift from a passive to an active return approach must be carefully evaluated. The CLSC network can benefit from an active return approach by developing appealing incentives for collectors and enhancing the positive effects of the blockchain. In contrast, consumer incentives can have detrimental effects on the blockchain. Various combinations of incentives can only bring a few business performance increases, while collector incentives are vital to reinforce the CE system's operational and service capabilities.

Originality/value

This paper takes a new approach toward the study of CE, which considers a dual circular system composed of a CLSC and a reverse omnichannel. The research explores whether the adoption of blockchain technology enables better return processes by improving the operations in CLSC and services in reverse omnichannel. Finally, this is the first empirical work to evaluate the benefits emerging from incentives, which can activate smart contracts in the blockchain and enable active return approaches in CE.

Abstract

Purpose

The purpose of this paper is to conclude this special issue on innovation in qualitative research by addressing the preceding papers in relation to the work of Human Resource Development (HRD) scholars and scholar-practitioners, consider the implications to the field of HRD and point to additional directions for innovative qualitative approaches. The authors use the term “innovative” to mean either an approach (or technique) that is newly conceived or one that is new to HRD (or little used).

Design/methodology/approach

The authors reviewed the papers in the special issue, identified other innovative qualitative approaches from the HRD literature and described briefly additional innovative approaches from other fields to suggest future directions for HRD professionals.

Findings

In this review, the authors noted the relatively few approaches to qualitative research that have been used regularly in HRD literature and suggested further innovative approaches that could deepen the understanding of organizations, including narrative, visual and indigenous methods, among others.

Research limitations/implications

This paper provides for HRD scholars an overview of a few qualitative research methodologies that are new to HRD and identifies additional approaches and epistemological challenges that could be valuable for future inquiry into complex organizations by HRD scholars and practitioners.

Practical implications

The authors suggest various feasible approaches and tools for HRD professionals to inquire into their practice in organizations to identify needs, evaluate outcomes and inquire into socially complex issues.

Originality/value

This study’s intent is to encourage the use of various innovative qualitative inquiry approaches when appropriate to understand and transform organizations. In particular, this study encourages the approaches that center the voices and experiences of those being studied and emphasizes the ways of listening to voices from the margins that may have been ignored previously.

The aim of this study is to identify the critical factors of green supply chain (GSC) and to adapt these factors to the taxonomy of green practices in healthcare.

Abstract

Purpose

The aim of this study is to identify the critical factors of green supply chain (GSC) and to adapt these factors to the taxonomy of green practices in healthcare.

Design/methodology/approach

A qualitative multiple-case study approach was followed based on 60 interviews with nine French hospitals. An intra-case and a cross-case analysis were implemented.

Findings

The findings provide a taxonomy of healthcare GSC and show that regulation, cost reduction, top management commitment, employee training, information technology and measures of environmental performance are critical factors for GSC implementation. The study also underlines a few emergent critical factors including the purchasing group, environmental champion, building construction, combining safety and green approaches.

Research limitations/implications

This study was conducted in France following a qualitative methodological approach. Future research can consider other national and cross-national investigations and other quantitative or mixed methods approaches.

Practical implications

The research provides managers and policy makers numerous invaluable suggestions for the implementation of GSC practices in healthcare facilities. To accelerate GSC implementation, managers can invest in the construction of new buildings, in information technology, and in the automation of flows.

Originality/value

To the authors’ knowledge, this is the first paper identifying the critical factors of GSC implementation in the healthcare sector. It is also the first attempt to provide a taxonomy of hospitals according to their green approaches (reactive, receptive, and proactive).
