Abstract
Purpose
This paper aims to investigate whether Brazilian firms that legally bond to stricter enforcement and commit to stringent corporate governance requirements experience increased value relevance of discretionary fair value measurements (Levels 2 and 3), and how different measurement levels are associated with firms’ systematic risk.
Design/methodology/approach
The Brazilian data’s distinctive feature helps in analyzing fair value’s relevance in an emerging market with heterogeneous enforcement regimes. Given the inherent self-selection in corporate governance levels and cross-listing decisions, the authors use a two-step generalized method of moments approach. Building upon Song et al.’s (2010) framework, the authors carefully address potential selection biases. Furthermore, the authors expand Riedl and Serafeim’s (2011) model, based on Ohlson’s (1995) model, to explore whether the negative correlation between Level 1 net assets (assets minus liabilities) and firms’ beta is more pronounced compared to Levels 2 or 3 net assets. Additionally, the authors investigate whether this relationship intensifies when firms align themselves with enhanced governance structures and stricter enforcement regimes.
Findings
Fair value measurements which require more judgment (Levels 2 and 3) are more value-relevant when a firm is legally bonded to higher enforcement and better corporate governance. Level 1 fair values of these firms’ net assets are associated with lower systematic risk, while Levels 2 and 3 fair values (high subjectivity valuation) are not.
Originality/value
The authors show that firms that bond to better corporate governance and stricter enforcement regimes mitigate the information risk involved in subjective fair-value measurements.

Abstract
Purpose
The purpose of this paper is to interpret the use of accounting information relating to the House of Correction, a public safety institution established in Rio de Janeiro for the control of workers under a tutelage system (1831–1864). The aim of the House of Correction was to develop a disciplined workforce of former slaves and other “Free Africans”. Various control and information procedures were put in place to monitor its achievement of this goal.
Design/methodology/approach
This study is based on historical archival research, mainly conducted at the National Archive of Rio de Janeiro and at the Brazilian National Library. The study uses Althusser’s ideology concept and the Marxist concept of reproduction of labour to show how accounting information enabled the administrator of the House of Correction to exercise control over the “Free Africans” consistent with the ideologies of the period and place.
Findings
The authors find that the House of Correction pursued a policy of ensuring “Free Africans” were docile, obedient and familiar with State ideology.
Research limitations/implications
The research is based on a single case study and it shows the need for both comparative and interdisciplinary analysis in order to increase an understanding of the use of accounting information in ancient prison contexts, as well as in contemporary situations.
Originality/value
This paper extends our knowledge of the use of accounting for the control of workers, who were either captive or repressed due to their ethnical differences; and it shows how ideology can be imposed through the use of accounting information. The authors extend theory by applying the Marxist and Althusserian concept of reproduction of labour to the case of “Free Africans”.

Abstract
Purpose
The purpose of this paper is to evaluate the pathological, biochemical and redox state parameters of liver tissue in Wistar rats treated from birth to adulthood (119 days) with cafeteria diet.
Design/methodology/approach
During the lactation, 6 liters of Wistar rats (dam + 8 pups each) were fed one of two diets: control (CTRL; n = 3) or cafeteria (CAF; n = 3) diets and water ad libitum. After weaning, the males were placed in individual cages, receiving the same diet offered to their respective dams (CTRL or CAF; n = 18) until adulthood. The following parameters were evaluated: absolute and relative liver weight; blood, liver and feces biochemistry; liver histology; and redox state of the liver.
Findings
When assessing the relative and absolute organ weight, no significant differences were found between the groups. The Cafeteria group exhibited higher values of serum LDL-c (p = 0.008), VLDL-c (p = 0.03) and triglycerides (p = 0.01), as well as several micro and macrovacuoles of fat accumulation, higher hepatic lipid (p = 0.03) and cholesterol (p = 0.0001) levels regarding Control group. Cafeteria group showed greater expression of glutathione-s-transferase (p = 0.03) and superoxide dismutase (p = 0.005) enzymes compared to the control group. In the case of the markers of oxidative stress, there was no difference between the groups.
Originality/value
A simple and standardized cafeteria diet caused an accumulation of fatty acids in liver tissue, inducing a state of hepatic steatosis besides an increased expression of antioxidant enzymes.

Abstract
Purpose
The purpose of this study is to evaluate the nutritional effects in Wistar rats of supplementation with stand-alone saturated fatty acid (SFA) or monounsaturated fatty acid (MUFA), the replacement of SFA by MUFA and the combination of both (SFA + MUFA) over a long period of time (13 weeks).
Design/methodology/approach
In total, 30 Wistar rats were used and randomly assigned to receive (n = 6): control – lab chow; lard (L20%) – lab chow with added lard (20%); olive oil (O20%) – lab chow with added olive oil (20%); lard replacement with olive oil (L20% –O20%) – during six weeks lab chow with added lard (20%) replaced by lab chow with added olive oil (20%) given during the past seven weeks of the trial; lard combination with olive oil (L10% + O10%) – lab chow with added lard (10%) and olive oil (10%). Food and caloric intake, weight gain, food and energy efficiency, body mass index, bone mineral composition and blood biochemistry were evaluated.
Findings
All diets with added fatty acids showed higher energy intake (p < 0.001), weight gain (p = 0.01), accumulation of adipose tissue (p = 0.02) and food and energy efficiency (p = 0.01) compared to the control group. All groups exhibited higher levels of blood triglycerides compared to the control group (p = 0.02). In addition, the L10% + O10% group developed hyperglycemia (p < 0.001); the L group showed higher amounts of non- high density lipoprotein (HDL-c) (p = 0.04); and the L20%−O20% group exhibited high levels of the triglyceride/HDL-c ratio (p = 0.04) in relation to the control.
Originality/value
These results indicate that regardless of the fatty acid type, consumption in large quantities of fatty acids for long periods of time can cause obesity and dyslipidemia.

Abstract
Purpose
The purpose of this study was to evaluate the increase in sensitivity of a single risperidone administration in relation to energy intake of Wistar rats treated with cafeteria diet from birth to adulthood (119 days).
Design/methodology/approach
During the lactation period, six litters of Wistar rats (dam + 8 pups each litter) were fed one of the following two diets: Control (n = 3) or Cafeteria (n = 3) diets and water ad libitum. After weaning, the males were placed in individual cages, receiving the same diet offered to their respective dams (Control = 18; or Cafeteria = 18) until adulthood (119 postnatal days). The following parameters were evaluated: food and energy intake; macronutrient intake; weight gain; adipose tissue relative weight; sucrose preference; food intake after an administration of risperidone (0.1 mg/kg body weight).
Findings
The Cafeteria group showed a higher energy intake in relation to the Control group (p < 0.001). The consumption of energy beyond the individual needs can be understood as a hyperphagic condition. Also, the Cafeteria group reported greater weight gain (p = 0.048) and accumulation of adipose tissue (p < 0.001) with respect to the Control group. These results indicate that the cafeteria diet generated obesity in animals. The Cafeteria group showed reduced sucrose preference (p = 0.031), which is associated with the development of anhedonia-like behavior. In the food intake test, risperidone showed a greater sensitivity in Cafeteria animals, promoting a decrease in their energy intake in relation to the Control group that received risperidone (p = 0.040).
Originality/value
The cafeteria diet promoted hyperphagia, anhedonia-like behavior and obesity in animals. Acute risperidone administration showed greater sensitivity in the Cafeteria group, with a decrease in energy intake. The reported effects may be related to a downregulation of the dopaminergic system in the NAc region.

Abstract
Purpose
The purpose of this study is to evaluate the chemical composition of unripe banana flour from Southeast Brazil and verify its nutritional, physiological and biochemical properties in adult Wistar rats.
Design/methodology/approach
Analysis of soluble solids, titratable acidity, pH, moisture, ash, lipids, proteins, carbohydrate, resistant and total starch and energy was obtained. In all, 18 male Wistar rats were given different concentrations of unripe banana flour (0, 10 and 20 per cent) and these assessments were performed: feed, caloric and water intake; weight gain; coefficient of food efficiency; weight of organs; body, tibia and femur length; total mineral of bones; and biochemistry of blood, hepatic fluids and feces.
Findings
Unripe banana flour showed a potential for weight control as well as increased fecal cholesterol excretion. These results showed the potential of unripe banana flour for obesity treatment and lipid excretion. Nevertheless, plasma triacylglycerol levels increased in the animals that received the largest amount of banana flour (20 per cent w/w), possibly because of the large amount of resistant starch in the flour, indicating the need for additional studies to confirm the mechanisms responsible for this increase.
Originality/value
Unripe banana flour may promote beneficial health effects (such as weight control and increased elimination of cholesterol in feces); however, the large amount of resistant starch present may be responsible for an increase in blood triacyglycerol.

Abstract
Purpose
The Sertão, located in the Northeastern region of Brazil, is the most populous semi-arid region in the world. The region also faces the highest rates of poverty, food insecurity and climate risks in this country. Basic economic activities, such as extensive livestock and dairy farming, tend to be mainly affected by the increasing temperatures and recurrent droughts taking place in the past decades. This paper aims to analyze farmers’ responses to climatic variability in the Sertão.
Design/methodology/approach
Analyses are based on farm-level data of the Agricultural Census 2006 and on historical climate data gathered by meteorological stations. The climate impacts and the effectiveness of adaptive strategies are compared between three groups of farms, which discriminate different levels of social and environmental vulnerability. Four production functions are modeled (milk, cattle, goat and sheep) accounting for sample selectivity bias.
Findings
In response to increasing temperatures, farmers tend to shift their activities mainly to cattle and dairy farming. But the overall productivity tends to reduce with the recurrence of droughts. Decreasing precipitation affects mainly the production of milk of smallholder family farmers and the cattle herd of non-family farmers.
Research limitations/implications
Analyses do not account for short- and medium-run productive impacts of extreme droughts, which usually have devastating socioeconomic effects in the region.
Originality/value
Smallholder family farmers are the most vulnerable group who deserve more social and technical intervention, as they lack basic social and technological resources that can greatly improve their productivities and overcome the impacts of decreasing precipitation.

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
The purpose of this chapter is to analyze the reflection of corruption in Brazilian companies listed on Brasil, Bolsa, Balcão (B3). The methodological design comprised a qualitative and descriptive approach in which documentary research was used to gather data. Content analysis was employed to treat data retrieved from Standard Financial Statements, Explanatory Notes, and Sustainability Reports, from 2013 to 2017. The findings reveal a low level of disclosure of the companies listed on B3 concerning the reflections of corruption. The disclosed reflections include the increase in the company's operating costs and the impact on the company's future cash flow which can be direct, such as through the reduction of revenues from canceled negotiations, or indirect, through transaction costs due to the misconduct of the company.

Abstract
This chapter analyzes the semiotic construction of US claims to sovereignty in Hawai‘i. Building on semiotic theories in sociology and theories within critical Indigenous and settler colonial studies, it presents an interpretive analysis of state, military, and academic discursive strategies. The US empire-state attempts to construct colonial narratives of race and sovereignty that rehistoricize the history of Hawaiians and other Indigenous peoples. In order to make claims to sovereignty, settler-colonists construct narratives that build upon false claims to superiority, advancement, and discovery. Colonial resignification is a process by which signs and symbols of Indigenous communities are conscripted into the myths of empire that maintain such sovereign claims. Yet, for this reason, colonial resignification can be undone through reclaiming such signs and symbols from their use within colonial metanarratives. In this case, efforts toward decolonial resignification enacted alternative metanarratives of peoples' relationships to place. This “flip side” of the synecdoche is a process that unravels the ties that bind layered myths by providing new answers to questions that underpin settler colonial sovereignty.
