Abstract

Purpose

The purpose of this paper is to analyze the financial friction effect of non-performing loans (NPLs) on financial intermediation (FI) through empirical evidence from the Brazilian experience.

Design/methodology/approach

The authors develop a new variable, financial intermediation flow and a new indicator, FI, both measures of FI. To empirically test FI, the authors use a dynamic panel data framework that draws on 101 banks (December 2000 to December 2015).

Findings

An increase in NPL reduces FI. Thus, NPL amplifies financial friction in FI. This result holds in different time frames, such as the pre-crisis period, the crisis period and the post-crisis period.

Practical implications

The FI measure developed in this study offers the policymakers a possibility to monitor financial stability.

Originality/value

This study adds to this debate by proposing a measure of FI derived from financial flows. This measure allows one to estimate the role of NPL as a financial friction that can pose a threat to financial stability.

Abstract

Purpose

The purpose of this paper is to determine the classic (static) and dynamic sensory profile of different bottled mineral water samples, and to evaluate the consumer’s liking of the products.

Design/methodology/approach

Classic quantitative descriptive analysis (QDA) and temporal dominance of sensations (TDS) were applied to four brands of bottled mineral water and the liking of the products was evaluated by consumers.

Findings

The dissolved mineral concentration is highly correlated to the liking and influences the sensory profile of the samples in a substantial way. The higher the mineral content, the lowest is the liking. Refreshing, residual plastic taste, musty, metallic taste, medicine taste and viscosity were relevant attributes to the samples differentiation through the static evaluation, while refreshing and viscosity were dominant in the dynamic monitoring. Some information might have been lost by the nature of the TDS method, based on dominance concept. Sweet taste contributed positively and musty taste negatively to the acceptance.

Originality/value

This paper demonstrated that TDS can be used as a complementary tool to the QDA, contributing to a deeper comprehension of the differences among samples, even in products with low differences, such as bottled mineral water.

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 purpose of this paper is to carry out a systematic review of the state of the art of the environmental training theme and to propose a research agenda to shed light on this subject by suggesting new research in the area.

Design/methodology/approach

This is a systematic review of the state of the art of the environmental training theme.

Findings

The authors’ main contribution is the proposal of a research agenda with 11 recommendations for future research, such as conducting research in developed countries; research focusing only on environmental training; qualitative research using case studies; research that explores the co-evolution of environmental training practices with environmental management practices and with the maturity stage of environmental management in organizations; and research that addresses all aspects of environmental training phases proposed by ISO 10015: 2001.

Originality/value

This is the most recent research which conducts a systematic review of the state of the art on environmental training and proposes a research agenda with several suggestions that can guide researchers in human resources, environmental management, sustainability and supply chain management.

Abstract

Purpose

This study aimed to evaluate the antimicrobial activity of the aqueous extract from jaboticaba skin against important foodborne bacteria and fungi and its stability.

Design/methodology/approach

Jaboticaba skin aqueous extract (at ratio of 10 g L-1) was tested against Listeria monocytogenes, Staphylococcus aureus, Bacillus cereus and Escherichia coli. Stability of the anti-staphylococcal activity, total phenolics, monomeric anthocyanins, tannins, phenolic acid content were measured and statistically correlated.

Findings

The residue extract inhibited L.monocytogenes, S.aureus, B.cereus and E.coli growth but was not effective against fungi and was stable to the thermal treatments, remaining with its inhibitory activity against S.aureus. When stored for 14 days at 25 °C with an incidence of light, there was a reduction in the antibacterial activity and in the phenolic compounds. The change in pH slightly changed polyphenolic content profile, and the exposure to papain and bromelain did not affect the antimicrobial activity. Results showed strong correlation between anti-staphylococcal activity, the presence of polyphenols and anthocyanins, meanwhile moderate correlation with phenolic acids content in the extract.

Originality/value

Biopreservatives are a great trend in food microbiology. The present work shows deeper information about the utilization of jaboticaba skin as antimicrobial agent and its stability, which is not found in the current literature.

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

The purpose of this paper is to study the immobilization of porcine pancreatic lipase (PPL), in an organic matrix by a covalent cross-linking method to sense propylparaben (PP) present in aqueous solution.

Design/methodology/approach

PPL immobilization was performed by the covalent cross-linking method, using bovine serum albumin (BSA) in the presence of saturated glutaraldehyde vapor (GA). The preparation of the enzymatic membrane involves the incorporation of porcine pancreatic lipase (PPL), bovine serum albumin (BSA) and glycerol into a phosphate buffer solution (PBS). Characterization of this sensor was performed by impedance spectroscopy (EIS) and scanning electron microscope (SEM). The effect of experimental conditions such as PPL activity, potential, scan rate, PP concentration, pH and presence of interfering elements were studied by cyclic voltammetry.

Findings

Under the optimal experimental conditions, a number of significant factors were optimized. The method exhibited good linearity in the range of 10–14 to 10–9 mol/L with a good correlation coefficient of 0.957, detection limit (LOD) of 3.66 × 10–15 mol/L and high sensitivity of 1.086 mA mol−1L. The authors also obtained a very good coverage rate of the surface equal to 91.44%, and hydrolytic activity of lipase is evaluated to 26.64 mmol min−1. The stability and the interference were also evaluated. The equivalent circuit used to explain the electrochemical behavior of modified electrode is a Randle circuit.

Practical implications

The main application of biosensors is the detection of biomolecules that are either indicators of a disease. For example, electrochemical biosensing techniques can be used as clinical tools to detect breast tumors, because these compounds (PP) were found in breast tumors.

Originality/value

The result registered in this paper indicates that the developed sensor is an efficient, fast, simple and inexpensive analytical tool that can be used for the analysis of water containing PP.
