Abstract
Purpose
Consumption of game meat is growing when compared to other meats. It is susceptible to adulteration because of its cost and availability. Spectroscopy may lead to rapid methodologies for detecting adulteration. The purpose of this study is to detect the adulteration of wild fallow deer (Dama dama) meat with domestic goat (G) (Capra aegagrus hircus) meat, for samples stored for different periods of time using Fourier transform infrared (FTIR) spectroscopy coupled with chemometric.
Design/methodology/approach
Meat was cut and mixed in different percentages, transformed into mini-burgers and stored at 3°C from 12 to 432 h and periodically examined for FTIR, pH and microbial analysis. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were applied to detect adulteration.
Findings
The PCA model, applied to the spectral region from 1,138 to 1,180, 1,314 to 1,477, 1,535 to 1,556 and from 1,728 to 1,759 cm−1, describes the adulteration using four principal components which explained 95 per cent of variance. For the levels of Adulteration A1 (pure meat), A2 (25 and 50 %w/wG) and A3 (75 and 100 %w/wG) for an external set of samples, the correlation coefficients for prediction were 0.979, 0.941 and 0.971, and the room mean square error were 8.58, 12.46 and 9.47 per cent, respectively.
Originality/value
The PLS-DA model predicted the adulteration for an external set of samples with high accuracy. The proposed method has the advantage of allowing rapid results, despite the storage time of the adulterated meat. It was shown that FTIR combined with chemometrics can be used to establish a methodology for the identification of adulteration of game meat, not only for fresh meat but also for meat stored for different periods of time.

Abstract
Purpose
This study aims to improve our understanding of violence, focusing on the analysis of the relation between socioeconomic factors and homicide rates from 2005 to 2019 in Brazilian capitals.
Design/methodology/approach
Multilevel Poisson models were used to estimate the homicide risk in men and women. The response variable was the homicide rate. Fixed effects were estimated for age group, year and gross domestic product (GDP).
Findings
The average homicide rate over the 2005–2019 period was 5.83/100,000 and 83.72/100,000 for women and men, respectively. In both sexes, the homicide rates increased over the period. The highest mortality rates were observed in North and Northeastern capitals. The peak homicide rates were 2010–2014, the risk of homicide decreased as age increased, and the capitals with GDP lower than US$5,000 showed a greater homicide rate.
Originality/value
Brazil remains among the countries with the highest risk of homicide, especially in the north and northeast regions, where socioeconomic conditions are more unfavorable. The improvement of socioeconomic conditions may contribute to changing this situation.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Purpose
The market system and a materialistic lifestyle have contributed to some of the environmental and social problems that currently affect the world. However, only a few consumers are willing to express ecological oriented consumption. This study aims to analyse how organic food consumers build a green identity, as well as the new expressions that arise from this identity construction.
Design/methodology/approach
A hermeneutical approach was adopted to address the narratives of 31 frequent consumers of organic products motivated by environmental issues. The narratives were collected through the interview method, which was further complemented by participant observation.
Findings
The following five phases of identity formation were identified: consciousness, gathering, negotiation, stabilisation and sharing. By looking at the different identity stages, it becomes visible how organic consumption and pro-environmental behaviours act as transformative practices, promoting ecological activism and fortifying a green identity.
Originality/value
This study extends the “processual theory of identity” by analysing how organic products help shape consumer practices and their lifestyle. Moreover, a contribution is provided on how we can build an ecological citizenship by reducing consumption and also by adopting alternative practices of consumption.

This study aims to analyse and measure the damage caused by acts of corruption in the largest investigation in Brazil, known as the “Lava Jato” operation.
Abstract
Purpose
This study aims to analyse and measure the damage caused by acts of corruption in the largest investigation in Brazil, known as the “Lava Jato” operation.
Design/methodology/approach
For the analysis of financial flows, documentary research was carried into denunciation and judicial decisions. Based on the “Follow the Money” methodology, it was possible to follow the inverse trail of money, from the indications of benefits to public agents, financial operators and fake companies up to the deviation of refinery construction.
Findings
The analysis allowed the identification of damages from acts of corruption that reached 17.8% of the value of the oil refineries built, while the benefit of the corrupting agents was 13.7% of the damage caused. The analysis shows several other characteristics of the movements and the identification strategy of financial crimes.
Research limitations/implications
Research enabled the development of a strategy to identify and measure the flow of corruption and money laundering.
Practical implications
Based on the identified financial parameters, it will be possible to estimate the damage caused by a corrupt act for a certain benefit.
Originality/value
The research identified financial parameters of damages and benefits from acts of corruption in the largest fraud that occurred in the country, which was replicated in modus operandi in several works and countries in Latin America.

Abstract
Purpose
Excessive sodium intake is associated with several diseases. Accordingly, several measures, including microparticulate salt, have been adopted to reduce the salt contents of food products. However, no studies have reported the effectiveness of microparticulate salt in semisolid and liquid products. Accordingly, the purpose of this paper is to evaluate the application of microparticulate salt to reduce sodium contents in semisolid products.
Design/methodology/approach
The optimal salt content to be added in butter was defined by the just-about-right-scale test. Butter samples were prepared using microparticulate salt to achieve 25, 50 and 75 per cent reductions in conventional salt concentrations. Multiple comparison tests were performed to evaluate sample taste.
Findings
The ideal concentration of conventional salt to be added to butter was 2.16 per cent. Discriminative tests showed that samples with 25 and 75 per cent salt reduction showed significant differences (p ⩽ 0.05) compared with butter prepared at the ideal salt content, whereas the sample with 50 per cent salt reduction had no significant difference (p > 0.05). Thus, microparticulate salt showed higher salting power than conventional salt. These results indicated the effectiveness of microparticulate salt in the preparation of semisolid products with sodium reduction.
Research limitations/implications
More detailed studies about the reduced-sodium butter shelf life are necessary to verify the microparticulate salt application in the product preparation. Moreover, microparticulate salt application in semisolid and liquid products elaboration must be more investigated to better elucidate its practicability of reducing sodium content in these kinds of products. Therefore, researchers are encouraged to test the proposed propositions further.
Practical implications
Microparticulate salt has been successfully applied to reduce sodium in solid products, being added to the finished product surface. However, there are no studies that report its effectiveness in semisolid and liquid products, such as the butter, in which the salt is added during the product preparation. Thus, this research provides new scientific information to the food industry and research fields, to expand the knowledge of reduced-sodium products development using microparticulate salt with sensory quality.
Originality/value
No studies have evaluated the application of microparticulate salt for semisolid product preparation. Therefore, the findings will support the development of healthy products.

Abstract
Purpose
Total quality management is a valuable approach to continuously improve the quality of organizations; however, scholars debate its applicability to services, which require specific best practices that are different from those related to manufacturing. Moreover, digitization is pervading all kinds of services, but little has been written about total quality service practices in digital-based companies. For this purpose, the authors provide a holistic model of total quality service that reflects the peculiarities of such companies, guided by the question: how do total quality service practices change in digital-based service organizations?
Design/methodology/approach
The authors conduct an illustrative case study on Healthware Group, a global integrated digital health organization, to evaluate theoretical assumptions about total quality service practices in the digital environment.
Findings
The findings allow to validate the model provided. In addition, the study enables them to observe the changes the authors are witnessing in service provision in the digital era and the consequent transformation of best practices. To be accurate, the authors cannot refer to a full transformation in digital-based companies but rather to the enrichment and extension of TQS practices. The best illustration of these conclusions has been summarized in a set of propositions corresponding to seven of the key levers of a TQS model.
Originality/value
The paper represents the first attempt to discuss the relationship between total quality service and digitalization, offering a set of propositions for academics and insights for practitioners. The model can be used as a tool to visualize the different levers that successful implementation of TQS in digital-based services companies can rely on.

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
This research examines the impact of integrating lean manufacturing (LM) principles and Industry 4.0 (I4.0) into the product development process (PDP) of manufacturing companies in southern Brazil, with the objective of improving market performance (MP).
Design/methodology/approach
A survey was conducted with 110 product development managers to evaluate the level of LM and I4.0 principles, PDP phases, and the improvement of MP. Quantitative analysis was employed to analyse the data, including confirmatory factor analysis (CFA) and ordinary least squares (OLS) hierarchical regression.
Findings
The study reveals that integrating LM and I4.0 principles in the PDP enhances product development and positively impacts the MP of manufacturing companies. Additionally, I4.0 partially mediates the LM-PDP relationship, while LM partially mediates the I4.0-PDP relationship, highlighting their interdependence rather than one being a prerequisite for the other.
Research limitations/implications
The study has limitations regarding its narrow focus on product development managers in Brazil and the absence of multiple case studies.
Practical implications
The study emphasises the importance of coordinated efforts in manufacturing companies to adopt and manage both LM and I4.0 principles, as they positively impact all phases of the PDP and ultimately contribute to the overall MP of the companies.
Originality/value
The novelty of this study lies in its systemic approach, examining the relationships and effects of LM and I4.0 principles on the PDP, and demonstrating how these effects manifest in manufacturing companies.
