Abstract
Purpose
Selecting which processes to improve plays a critical role in the first phase of the business process management lifecycle, but it is a step with known pitfalls. Decision-makers rely on subjective criteria and their knowledge of the alternative processes put forward for selection is often inconsistent. This leads to poor quality decision-making and wastes resources. The purpose of this paper is to examine the proposition that decision-makers armed with context-enriched criteria make more logical, better-quality decisions. The context in question is qualitative, sensitive to decision-making bias and politically charged.
Design/methodology/approach
We applied a design-science approach, engaging 70 industry decision-makers through a combination of research methods to assess how different contextual configurations, in a hypothetical scenario adapted from the Australian banking industry, influenced and ultimately improved the quality of the process selection step.
Findings
The study highlights the impact of framing effects on context, and the need to adapt framing to decision-maker behavior and provides five guidelines to improve process selection effectiveness.
Originality/value
Process selection research to date has largely focused on quantitative evaluation techniques, with little attention paid to the role of context and the behavioral interplay of decision-making styles in practice.

Abstract
Purpose
This study, a practice forum article, aims to presents the lessons learned and the development of a discrete event simulation model to support the funerary system management of São Paulo City, Brazil, during the COVID-19 pandemic.
Design/methodology/approach
A discrete event simulation model was developed by the authors as soon as the pandemic affected the city of São Paulo, Brazil. Based on the model, several scenarios with varying minimum, median and peak demands (i.e. the number of deaths) were tested and evaluated. The lessons learned from the scenario analysis and implementation of the decision-making of the city government of São Paulo are discussed in this article.
Findings
The lessons learned about the coordination, inventory management and other operational characteristics in funerary logistics during the pandemic are shared with a model, which quantifies the demand for vehicles, coffins, graves and teams in the cemeteries in different simulated scenarios.
Practical implications
The São Paulo State Civil Defense used this information during the pandemic to prepare the funerary system of the municipality.
Social implications
The study presents methods to mitigate the sanitary, environmental and psychosocial problems related to the funerary system.
Originality/value
Studies on funerary systems are scarce. This study presents the results that supported the dimensioning of the funerary system during the pandemic and operational lessons about the logistics to support decision-making in future events.

Abstract
Purpose
The purpose of this paper is to identify critical success factors (CSFs) that are regarded as the most important in Six Sigma programs in Brazil and to compare these rankings with those in international literature.
Design/methodology/approach
A sample of industrial companies was selected to complete a survey. In total, 104 questionnaires were obtained. The results were compared with a literature review consisting of 26 papers from 13 countries. In total, 70 CSFs were found in the papers, but 19 CSFs were analyzed and reduced to ten. A multivariate factor analysis further reduced this number to two underlying constructs.
Findings
The authors identified a CSFs common denominator/ranking based on the sample of international articles. The authors found that there are four CSFs that are more prevalent in Brazil and in the international papers studied and that there are no differences between the importance of CSFs in terms of hierarchical levels. Three gaps, five levers and two CSFs constructs were identified.
Social implications
This study may initiate cooperation between the studied companies and academia, thus possibly increasing these organization’ knowledge regarding Six Sigma.
Originality/value
The originality of this study is that the survey was conducted with companies in Brazil, a country where little information exists on Six Sigma programs. The authors also contributed a literature review on CSFs, a comparison based on most of the consulted papers and the use of a robust methodological strategy that was made possible by the sample size.

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
This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.
Design/methodology/approach
The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.
Findings
This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.
Originality/value
The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

Abstract
In his review of 30 years of research in Prospect Theory, Barberis (2013) notes that support for Prospect Theory had come mainly from the laboratory. In this paper, I write about a recurring phenomenon in real life that is consistent with Prospect Theory predictions in decision-making loss domain. The 60 cases noted in this paper are associated with specific risk seekers that had cost more than $140 billion (an average of $2.33 billion per case). Given space consider– ations, I provide synopses for 14 cases. A few of these cases have been discussed in the extant literature in connection with internal control, but were not considered from the perspective of Prospect Theory. It is striking that these cases are costly, all participants are young men, and almost all had followed the gambler’s martingale strategy – i.e., double down. While these cases are informative about risk-seeking behavior, they are not sufficiently systematic to be subjected to stylized archival research methods.
