Abstract
Purpose
The purpose of this paper is to examine the relationship between leave policies and social inequalities. It seeks to analyze the historical course of maternity and paternity leave legislation in Brazil, and also provides quantitative evidence that access to leave is impacted by social stratification, revealing different inequalities.
Design/methodology/approach
To investigate access to leave policies, this study uses data from the Pesquisa Nacional por Amostra de Domicílios Contínua Anual de 2017 (Annual National Continuous Household Sampling Survey of 2017), conducted by IBGE/Brazil.
Findings
The results point out the existence of inequalities in the conceptions of leave policies in Brazil, and lead to quantitative confirmation that access to leave is stratified and permeated by inequalities of gender, class, race and age.
Social implications
By pointing out the social inequalities resulting from the contributory scheme of maternity and paternity leave, the results of this paper may generate debate on the transformation of leave into a universal right of citizens and impact public policy agenda in the future.
Originality/value
This is the first Brazilian study to analyze the relationship between leave policy and social inequality through quantitative data, showing the existence of social stratification of gender, class, race and age concerning the employed population’s access to maternity and paternity leave.

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
Purpose
Different from most academic publications about tourism in Brazil, this paper provides an overarching and comprehensive perspective. Analysing key developments, and focusing on the period 2000–2019, this paper also considers long-standing structural issues that hinder tourism development. Although this viewpoint paper deals with Brazil, very similar issues can be identified for many countries worldwide.
Design/methodology/approach
This viewpoint paper is a combination of reflections by leading Brazilian tourism academics; most are members of ABRATUR, the International Academy for the Development of Tourism Research in Brazil. This paper uses secondary data from the grey (e.g. government reports) and academic literature to support this opinion paper. The tourism-related topics covered in this paper include economics, policy and planning, marketing, transport, nature-based tourism, gastronomy, hospitality and education, amongst others.
Findings
Brazil has missed several unique opportunities to place it as a destination of international renown. Since the 1990s, efforts to support regional tourism development have achieved only moderate success as political instability, violence and corruption have impacted tourism. A lack of a coordinated approach between the various levels of government, a shortage of tourism data and a long-term supra-government marketing campaign, among other factors, have meant Brazil has missed several critical opportunities in the 2010s to establish itself as a leading tourism destination in the global market.
Originality/value
From leading tourism academic experts in Brazil, a unique opinion paper offers an overview of the critical development issues in 2000–2019. The paper presents matters that have hindered potential tourism contributions to the largest nation in South America. While these matters may be specific to Brazil, many of these challenges are not dissimilar to those in other emerging (democratic) nations. The authors offer several public policies and technical recommendations to scaffold tourism development towards the 2030 agenda.

Abstract
Purpose
This study aims to proposed that blockchain helps the organization improve supply chain (SC) performance by improving integration, agility and security through real-time information sharing, end-to-end visibility, transparency, data management, immutability, irrevocable information and cyber-security platforms.
Design/methodology/approach
This study has made an initial effort toward proposing a framework that shows the problems and challenges for the O&G SC under its segments (upstream, midstream and downstream) and provides the interlink among blockchain properties for SCM problems. SC managers were selected for survey questionnaires from the Pakistan O&G industries.
Findings
This study analyzes the impact of blockchain-enabled SC on firm performance with an understanding of the SC robustness capabilities as a mediator. The result revealed that the SC manager believes that the blockchain-enabled SC has a positive and significant on firm performance and robustness capabilities.
Research limitations/implications
Blockchain technology is reflected as high-tech to support the firm process, responses and methods. The technology helps eliminate bottlenecks, avoid uncertainties and improve decision-making, leading to improved SC functions. This study guides managers about the potential problems of existing SC and how blockchain solves SC problems more effectively.
Originality/value
The oil and gas (O&G) sectors are neglected by researchers, and there are limited studies on O&G supply chain management (SCM). Additionally, no empirical evidence suggests implementing blockchain for O&G as a solution for potential problems. Furthermore, present the roadmap to other industries those having complex SC networks for the implication of blockchain to improve the SC performance.

Abstract
Purpose
The purpose of this work was to develop a new trispiperazido phosphate-based reactive diluent (diphosphate-piperazine hydroxyl acrylate [DPHA]) and used as a flame retardant with an epoxy acrylate (EA) in ultraviolet (UV)-curable wood coating.
Design/methodology/approach
The concentration of reactive diluent was varied from 0% to 20% in the UV-curable formulation with constant photoinitiator concentration. The effect of DPHA concentration on film properties was studied by differential scanning calorimetry and thermogravimetric analysis, gel content, water absorption and limiting oxygen index.
Findings
The results showed that the viscosity of the prepared formulation decreased by increasing reactive diluent (DPHA) concentration which leads to improving the coating efficiency. A high concentration of reactive diluent (DPHA) of the cured films shows good resistance against stain, mechanical and thermal properties, which results in an increased glass transition temperature (Tg) and cross-linking density of the films.
Originality/value
The new trispiperazido phosphate-based reactive diluent was used in wood coating formulation, which resulted in excellent flame-retardant properties with higher cross-linked density with good stain resistance. This material can provide a wide range of application for coating industries to produce a glossy finish.
