Abstract

Purpose

Reverse logistics (RL) is a waste revaluation process aimed at reintroducing once-used materials back into the production cycle. Public administration (PA) plays a strong role in influencing the implementation of RL in the construction industry through policy and laws. While much research identifies PA as an important driver in RL, no research yet describes how this occurs.

Design/methodology/approach

A systematic literature review was conducted on the theme PA in RL with 93 relevant publications retrieved.

Findings

Six strategies used by PA to promote RL were extracted: (1) legislation, (2) government subsidies, (3) landfill disposal fee, (4) government inspection, (5) use in public construction works and (6) penalties and fines. Moreover, a typology built on these six strategies was developed, mapping 15 interactional relationships between strategies, according to three levels of influence: (1) encouragement (2) requirement and (3) regulation.

Practical implications

It was found that legislation and government subsidies prove to be the more effective strategies, with the remaining strategies greatly neglected. Importantly, however, this study reveals that a combination of strategies are most effective when appropriately combined.

Originality/value

This study confirms the importance of PA in RL, in construction, while documenting the extent of current research. The resulting proposed typology, along with 15 identified future research priorities, is expected to be of value to academics and policy makers looking to advance understanding in this domain.

Abstract

Purpose

The purpose of this paper is to evaluate the potential use of natural colorant extracted from fruit flesh and leaves of Cucumis melo L. (C. melo L.) in coating applications.

Design/methodology/approach

Carotenoids and chlorophylls compounds were extracted from C. melo L. fruit flesh and C. melo L. leaves with the best extraction solvents. Both compounds were tested at various pH for colour stability tests. Then, the most stable pH of both extracts was mixed with 20 per cent poly methyl methacrylate (PMMA) together with tetrahydrofuran and acrylic polyol to form a coating system on glass slides. The coated glass slides were exposed to three different temperatures. The effects of heat on the coated glass slides were evaluated using spectrophotometer at 400-700 nm wavelengths.

Findings

Results revealed that carotenoids extracted from C. melo L. were less stable to be applied in coating applications since the colour degraded in a very short time; however, the chlorophylls extracted were more stable where the colour retained for longer duration.

Originality/value

The method of the plant pigment production of C. melo L. with PMMA was a modified method that could give other various applications as natural product based on plant pigments.

Abstract

Purpose

Food service demands a greater concern with food security, as around two million people in the world, among them the majority of children, die from foodborne diseases. The purpose of this study deals with the adoption of the COOK CHILL system, in the principles of the hazard analysis and critical control point system (HACCP), within a food and nutrition unit of a petroleum refinery, to enable food security and cost reduction operational services in food services by using the traditional method of food production. To do so, hygienic-sanitary diagnosis based on Brazilian ANVISA standards is carried out.

Design/methodology/approach

The company that served as an object for the case study is an oil refinery located in the northeast region of Brazil, divided into 55 units with a production capacity of 323.000 barrels/day. For reasons of confidentiality, it will be referenced throughout the text of this work as Refinery.

Findings

With the implementation of the system, it was possible to reduce operational costs, food waste and energy and to provide safe food and increasing customer satisfaction.

Originality/value

The improvement achieved with the production of food quality was the adoption of the COOK CHILL system in the application of HACCP through the use of value (D) to control the biological CCP and monitoring through the control sheets.

Abstract

Purpose

The aim of this research is to propose a quantitative approach to evaluating the quality of services provided, helping organizations to make strategic decisions by better understanding the characteristics that satisfy consumers.

Design/methodology/approach

The approach was based on the integration of the Kano model with SERVQUAL, adapted by the satisfaction equations of Albuquerque et al. (2022) and fuzzy systems theory. Through this, it was possible to infer which attributes influence customer satisfaction, identifying the ranges of satisfaction and, with the help of fuzzy, reducing the imprecision of customer perceptions.

Findings

A total of 42% of the attributes were classified as unidimensional, with attribute 11 (Reliability) and attribute 9 (Courtesy) having the highest satisfaction values. Attractive attributes accounted for 38% of the sample, with attribute 29 (Variety of products) and attribute 7 (Location) having the greatest impact on satisfaction. On the other hand, attribute 30 (Order Delay) and attribute 31 (Waiting for payment) caused more dissatisfaction among consumers (ranges −0.6, −0.71, respectively). In addition, Variety of products was the most satisfactory, while Order Delay generated the most dissatisfaction among users.

Originality/value

The originality of this research lies in its contribution to organizations in relation to the services offered by investigating a gap in the studies that use the Kano model, integrated with SERVQUAL, which do not include reverse attributes in their equations and analyses. With the help of fuzzy sets, the subjectivity of the individual can be translated into data for greater clarity of information.

Abstract

The extant literature provides much-needed support to understand marketing accountability and how marketing actions are related to financial performance (FP). However, we have limited understanding of the relationships between marketing actions and firms' social performance (SP) and environmental performance (EP). Understanding these links is critical to enhancing sustainable FP, SP, and EP. Moreover, the literature provides limited understanding of the measures by which SP and EP may be operationalized, or the data necessary to reach a conclusion. This study bridges these gaps by extensively reviewing the extant literature to offer a set of measures and data sources to operationalize SP and EP, and empirically show their relationships with marketing actions. We find that greenhouse gas (GHG) emission, environmental disclosure score, waste reduction, energy consumption, and recycling are prominent measures of EP, and that social disclosure score, philanthropy or community spending, and diversity of gender and race are prominent measures of SP. The KLD, ASSET4, and Bloomberg are prominent sources of data that can be used to operationalize SP, to which CDP may be added for EP. We also show that marketing actions positively affect EP and SP. This study contributes to the extant literature on SP and EP by identifying measures and data sources and linking marketing actions to both performance types. It contributes to policy development by identifying the importance of EP and SP and how marketing actions can help achieve such performance.

Abstract

Purpose

Value at risk (VaR) is a market risk measure widely used by risk managers and market regulatory authorities, and various methods are proposed in the literature for its estimation. However, limited studies discuss its distribution or its confidence intervals. The purpose of this paper is to compare different techniques for computing such intervals to identify the scenarios under which such confidence interval techniques perform properly.

Design/methodology/approach

The methods that are included in the comparison are based on asymptotic normality, extreme value theory and subsample bootstrap. The evaluation is done by computing the coverage rates for each method through Monte Carlo simulations under certain scenarios. The scenarios consider different persistence degrees in mean and variance, sample sizes, VaR probability levels, confidence levels of the intervals and distributions of the standardized errors. Additionally, an empirical application for the stock market index returns of G7 countries is presented.

Findings

The simulation exercises show that the methods that were considered in the study are only valid for high quantiles. In particular, in terms of coverage rates, there is a good performance for VaR(99 per cent) and bad performance for VaR(95 per cent) and VaR(90 per cent). The results are confirmed by an empirical application for the stock market index returns of G7 countries.

Practical implications

The findings of the study suggest that the methods that were considered to estimate VaR confidence interval are appropriated when considering high quantiles such as VaR(99 per cent). However, using these methods for smaller quantiles, such as VaR(95 per cent) and VaR(90 per cent), is not recommended.

Originality/value

This study is the first one, as far as it is known, to identify the scenarios under which the methods for estimating the VaR confidence intervals perform properly. The findings are supported by simulation and empirical exercises.

Abstract

Purpose

This study aims to identify sustainability indicators in the energy sector through a literature review and validate them from the perspective and context of professionals working in the sector in an emerging economy country, Brazil, considering the relationship of these indicators with the achievement of the targets set by the United Nations sustainable development goals (UN SDGs).

Design/methodology/approach

To accomplish this, a literature review on sustainability indicators specific to the energy sector was conducted. Subsequently, a research instrument (questionnaire) based on the identified indicators was developed and a survey was administered to professionals in the field. The collected data were analyzed using the Lawshe method.

Findings

The results revealed 20 indicators, distributed across environmental, economic and social dimensions. Among these, nine indicators were validated, including global impacts, local impacts, renewable energy production as a percentage of total production, greenhouse gas emissions, access to electricity, investment in the energy sector, installed capacity in the electricity sector, energy prices in the end-use sector and energy distribution and conversion efficiency.

Originality/value

Consequently, it was possible to determine which SDGs are directly impacted and provide a foundation for future actions that can contribute to the sustainable advancement of the energy sector in emerging countries.

Abstract

Purpose

This paper aims to map the creation and evolution of centering resonance analysis (CRA). This method was an innovative approach developed to conduct textual content analysis in a semi-automatic, theory-informed and analytically rigorous way. Nevertheless, despite its robust procedures to analyze documents and interviews, CRA is still broadly unknown and scarcely used in management research.

Design/methodology/approach

To track CRA’s development, the roadmapping approach was properly adapted. The traditional time-based multi-layered map format was customized to depict, graphically, the results obtained from a systematic literature review of the main CRA publications.

Findings

In total, 19 papers were reviewed, from the method’s introduction in 2002 to its last tracked methodological development. In all, 26 types of CRA analysis were identified and grouped in five categories. The most innovative procedures in each group were discussed and exemplified. Finally, a CRA methodological roadmap was presented, including a layered typology of the publications, in terms of their focus and innovativeness; the number of analysis conducted in each publication; references for further CRA development; a segmentation and description of the main publication periods; main turning points; citation-based relationships; and four possible future scenarios for CRA as a method.

Originality/value

This paper offers a unique and comprehensive review of CRA’s development, favoring its broader use in management research. In addition, it develops an adapted version of the roadmapping approach, customized for mapping methodological innovations over time.

Abstract

Purpose

This paper aims to contextualize the process of public hospital providing services, based on the measurement of the performance of Federal University Hospitals (HUFs) of Brazil, using the technique of multivariate statistics of principal component analysis.

Design/methodology/approach

This research presented a descriptive and quantitative character, as well as exploratory purpose and followed the inductive logic, being empirically structured in two stages, that is, the application of principal component analysis (PCA) in four healthcare performance dimensions; subsequently, the full reapplication of principal component analysis in the most highly correlated variables, in module, with the first three main components (PC1, PC2 and PC3).

Findings

From the principal component analysis, considering mainly the component I, with twice the explanatory power of the second (PC2) and third components (PC3), it was possible to evidence the efficient or inefficient behavior of the HUFs evaluated, through the production of medical residency, by specialty area. Finally, it was observed the formation of two groups composed of seven and eight hospitals, that is, Groups II and IV, which shows that these groups reflect similarities, with respect to the scores and importance of the variables for both hospitals’ groups.

Research limitations/implications

Among the main limitations, it was observed incomplete data for some HUFs, which made it impossible to search for information to explain and better contextualize certain aspects. More specifically, a limited number of hospitals with complete information was dealt with for 60% of SIMEC/REHUF performance indicators.

Practical implications

The use of PCA multivariate technique was of great contribution to the contextualization of the performance and productivity of homogeneous and autonomous units, represented by the hospitals. It was possible to generate a high quantity of information, to contribute with assumptions to complement the decision-making processes in these organizations.

Social implications

Development of public policies, with emphasis on hospitals linked to teaching centers represented by university hospitals. The projection of improvements in the reach of the efficiency of the services of assistance to the public health, from the qualified formation of professionals, both to academy, as to clinical practice.

Originality/value

The originality of this paper for the scenarios, Brazilian public health sector and academic area involved the application of a consolidated performance analysis technique, that is, PCA, obtaining a rich work in relation to the extensive exploitation of techniques to support decision-making processes. In addition, the sequence and the way in which the content, formed by object of study and techniques, has been organized, generating a particular scenario for the measurement of performance in hospital organizations.

Abstract

Purpose

The purpose of this paper is to establish the need and the importance of adopting a structured model to support the decisions by using a multicriteria focus to guide drawing up a methodological framework. In addition, this study considers the maturity level of the organization, and the importance of continuous improvement after implementing ISO 9001.

Design/methodology/approach

This study presents a scientific technical foundation of the qualifying and selection criteria of the consultancy and Accredited Certification Body (ACB) by using ISO standards, and the guidance document CB25, which is related to quality. Finally, a numeric application with realistic data is undertaken using the PROMETHEE II method, and the GAIA plan.

Findings

The development of this study provides a new insight into the importance for selecting consultancy, and certification services in order to implement quality management systems within organizations.

Research limitations/implications

The current study is limited to the quality management services. If necessary to apply the same model to other areas, it is necessary looking for documents and regulations of this field. In addition, this model is focussed on a model for small or medium companies, which are still trying to achieve a higher position in the sector, and do not have experts in quality management.

Originality/value

The differential of this study is the foundation of the criteria for the proposed model. Other studies choose these criteria without any scientific basis. On the other hand, this study goes over many documents.
