Abstract

The unknown current distribution (UCD), line leakage current density (LLCD) and other integral characteristics of a linear grounding structure (GS), shaped either as an arbitrary linear star (LS) or polygon (LP), are presented in this paper. The UCD of the GS is determined by numerical solving of system of integral equations of two‐potential (SIE‐TP). The GS is placed in homogeneous and isotropic earth and its integral characteristics are analysed in the power frequency domain.

Abstract

Purpose

The purpose of this paper is to estimate influence of the pillar concrete foundation approximated by a semiconducting semi‐sphere on the pillar grounding system.

Design/methodology/approach

Unknown current distributions and impedance of pillar grounding system, which consists of a ferro armature modelled as a single electrode inside concrete foundation, ring electrode and two earthing conductors, are determined in this paper. Concrete foundation is approximated by a semi‐spherical semiconducting inhomogeneity. The expressions for electric scalar potential are formed using the quasi‐stationary image theory, including a recently proposed Green's function for the point source in the presence of a semiconducting sphere. Based on the quasi‐stationary antenna model, unknown currents are determined solving the system of integral equations using the moment method and polynomial approximation for current distributions.

Findings

The influence of inhomogeneity is not negligible for real values of specific conductivity of the inhomogeneity domain. The same goes for earthing conductor influence, especially the one on electric scalar potential distribution on the ground surface.

Practical implications

Besides the analyzed system, the model is applicable for solving for example a grounding system in the vicinity of large holes in the ground (pond and small lake) filled with water, treated as semi‐sphere or near vertical container (silage and reservoir) having semi‐spherical basis with a lower one buried in the ground.

Originality/value

Obtained results give possibility to analyze influence of semiconducting ground inhomogenities, which can be treated as semi‐spherically shaped ones, on grounding system. It results in better accordance of projected and real grounding system's characteristics.

Abstract

Purpose

The purpose of this paper is to investigate the ability of the computer vision system (CVS) to evaluate the colour of poultry meat. The advantages of the CVS over traditional methods were also explored.

Design/methodology/approach

The research was carried out on m. pectoralis major samples of three animals for each of the following four species: chicken, turkey, duck and goose. The total colour difference (ΔE) and the degree of difference of hue, chroma and lightness between the methods were calculated. In addition, a trained panel of 14 people was used to carry out three different similarity tests analysed using χ2 one sample test and one-way ANOVA. The correlation coefficient between CVS and colourimeter measures was evaluated using the Spearman rank correlation test.

Findings

The total colour difference (ΔE) between the methods employed was so large that the generated colour(s) could be considered more opposite than similar. The CVS-generated colour chips were more similar to the sample of the meat products visualised on the monitor compared to colourimeter-generated colour chips in all (100 per cent) individual trials performed. The use of the colourimeter for colour evaluation of lighter coloured poultry meat (chicken and turkey) was unrepresentative.

Practical implications

In this study, a CVS was developed to measure the colour of poultry meat as an alternative to conventional colourimeters.

Originality/value

The research has demonstrated that the use of a CVS should be considered a superior alternative to the traditional method for measuring colour of chicken, turkey, duck and goose meat.

Abstract

Purpose

To present the internal dialogue of a TQM practitioner using the conceptual lens of reflective practice.

Design/methodology/approach

This study used a pragmatic philosophical approach to collect qualitative critical reflection data and quantitative career construction data from stratified and purposively sampled respondents, using structured questionnaires. The qualitative data were analyzed through reconstruction, while the quantitative data were analyzed through co-construction using the percentage agreement value and Wilcoxon–Mann Whitney test.

Findings

Five questions were found to be valuable for steering the internal dialogue for critical reflection, thus recommended as a must-have in a TQM practitioner's toolkit. This study found the career adapt–abilities scale to be a valuable tool for assessing the career construction of a TQM practitioner. This was supported by a 64% agreement and non-significant difference between the two groups of raters used, p < 0.05 (U = 3356.5, W = 7451.5, Z = 1.9826), two-tailed.

Research limitations/implications

The pragmatic philosophical stance used in this study lends it to a certain level of subjectivity. However, the inputs from the three other participants neutralize the subjectivity. Most notably, this study is not about consensus-seeking but rather verifiable/testable self-reflection.

Practical implications

The theory-informed results presented in this study are useful for the continuing professional development of TQM practitioners.

Originality/value

This study provides insights for applying an individual-level self-assessment tool for TQM implementation.

Abstract

Purpose

The existing gaps and knowing about the truth inspired the researchers to select this area and to know more about various initiatives taken for their liberation by an individual self-propagating effort, the faith-based communities, the government, the organizations dealing with educationalists as researchers, banking, media and the revealing role of women in handling poverty concerns.

Design/methodology/approach

The current study is compiled after the review of seventy-seven research articles. This study adopted a descriptive research design essentially because it appears more appropriate for the study. Data were collected mainly through the secondary sources such as electronic databases like Scopus, Web of Science, EBSCO, Google Scholars. The study is conducted through a qualitative approach.

Findings

Hence based on the extensive literature review and its synthesis, this research work explores the meaning of poverty, its effects, root cause, measurement tools, associated theories and models and stakeholders' role in poverty alleviation.

Research limitations/implications

This study reflects that there is a huge gap in designing standardized tools that can bring more income equality, ethics in operations, cooperation and environmental sustainability.

Practical implications

For poverty alleviation, individuals need to work towards perfection and improving their own skill sets. Leading Faith groups encouraging individuals about their divine duties to help the poor community and promote debt forgiveness. Government provides funds to develop certain tools and app that can help in checking the distribution of wealth. Banks to introduce flexible microcredit scheme education sector need to develop more financial literacy and innovative thinking courses. Social media and Information communications technology (ICT) provide connectivity services with high affordability.

Social implications

Poverty will remain be an ongoing societal challenge if not handled by various stakeholders strategically by contributing in their own fields with their unique ideas.

Originality/value

The proposed idea explained through qualitative inquiry promotes compassion and hope needed for poverty alleviation through various stake holders.

Abstract

Purpose

Exposure to poor indoor air in refurbished buildings is a matter of health concern due to the growing concentrations of various contaminants as a result of building airtightness without amendment of ventilation, or the use of building materials such as glue, paint, thinner and varnishes. Recent studies have been conducted to measure indoor air pollutants and assess the health risks affecting the quality of life, productivity and well-being of human beings. However, limited review studies have been recently conducted to provide an overview of the state of knowledge. This study aims to conduct a scoping review of indoor air quality (IAQ) in the context of refurbished or energy-retrofitted buildings.

Design/methodology/approach

A systematic screening process based on the PRISMA protocol was followed to extract relevant articles. Web of Science, Scopus, Google Scholar and PubMed were searched using customised search formulas. Among 276 potentially relevant records, 38 studies were included in the final review covering a period from 2015 to 2022.

Findings

Researchers mapped out the measured compounds in the selected studies and found that carbon dioxide (CO2) (11%) and total volatile organic compounds (11%) were among the most commonly measured contaminants. Two trends of research were found including (1) the impact of ventilative properties on IAQ and (2) the impact of introducing building materials on IAQ.

Originality/value

The contribution of this study lies in summarising evidence on IAQ measurements in refurbished buildings, discussing recent advancements, revealing significant gaps and limitations, identifying the trends of research and drawing conclusions regarding future research directions on the topic.

Abstract

Purpose

The aim of this paper states that total productive maintenance (TPM) is an improvement tool which employs the effective utilization of employees in order to enhance the reliability of the equipment in consideration.

Design/methodology/approach

This paper identifies and evaluates the factors accountable for the adoption of TPM methodology in manufacturing organizations. Twenty-four factors affecting the TPM implementation are explored and categorized into five significant categories. Afterwards, these identified TPM factors have been evaluated by using a most popular Multi-criteria decision-making (MCDM) approach namely fuzzy pivot pairwise relative criteria importance assessment (F-PIPRECIA).

Findings

In this paper, through application of F-PIPRECIA, “Behavioural factor” is ranked first while “Financial factor” the last. Considering the sub-factors, “Top management support and commitment” is ranked first while “Effective use of performance indices” is ranked the last. A further sensitivity analysis indicates the factors that need higher level of attention.

Practical implications

The result of current research work may be exploited by the top administration of manufacturing enterprises for assessing their TPM adoption status and to recognize the frail links of TPM application and improve accordingly. Moreover, significant factors of TPM can be identified and deploy them successfully in their implementation procedure.

Originality/value

The conclusion obtained from this research enables the management to clearly understand the significance of each considered factor on the adoption of TPM in the organization and hence, provides effective utilization of resources.
