Abstract

Purpose

The application of coatings on metal substrates can provide an increase in corrosion resistance in the environment where the material is employed. The use of silane causes low environmental impact and may represent an alternative to replace chromates and phosphates applied as a pretreatment prior to surface painting. The objective of this study was to evaluate experimental parameters for the investigation of the formation of a vinyltrimethoxysilane (VTMOS) monolayer on 1010 carbon steel applying electrochemical techniques.

Design/methodology/approach

A total of 24 types of coated samples were obtained, following three 23 factorial design of experiments (DOE), and one uncoated. The VTMOS monolayer was formed by hand dip process, followed by curing in a stove, using substrates of sanded, pickled and degreased 1010 carbon steel and hydrolyzed silane.

Findings

The results of coated samples were satisfactory as compared to those of uncoated carbon steel, as the former were better protected against corrosion.

Originality/value

This paper shows an evaluation of experimental parameters that influence the formation of a film of silane VTMOS on 1010 carbon steel by means of electrochemical techniques. The results indicated that the silane monolayer VTMOS promotes enhanced properties that prevent corrosion of 1010 carbon steel and the method of film formation directly influences the properties of such protection.

Abstract

Purpose

The main purpose of this study is to present an analysis of the dynamics of the tourism market in South America and, more specifically, in Brazil, by measuring and analyzing the growth in tourists' arrivals to the region between 1998 and 2002.

Design/methodology/approach

This study uses the shift‐share technique that decomposes the growth of the number of tourists into various components, enabling in‐depth diagnosis of the dynamics of the sector in the period.

Findings

Despite the fact that Brazil is the leading tourist destination in South America, the study shows that Brazil has been losing ground in relation to some of its neighbors in South America. The study also revealed the impact of 9/11 and Argentina's crises and the growing participation of the European tourist in Brazil.

Originality/value

Despite some limitations, this technique has the advantage of focusing on a region scarcely studied in mainstream tourism researches and offering Brazilian policy‐makers a new methodology such that they may take advantage of emerging opportunities and create competitive advantages for the country.

Abstract

The objective of this chapter is to illustrate how globalization affects labor mobility and work. The impact of globalization ranges from a profound restructuring of productive agriculture and rural labor markets to the forms through which production and labor are controlled – including the internal and external systems of food quality and safety standardization. These aspects require a broad readaptation and modernization of food distribution models and the standardization of technical principles. In the sector of local food distribution, these changes have significantly affected the lives of those involved, especially in terms of increased competitiveness and the escalation of the demands associated with the enhancement of the quality of products. Moreover, accelerated technological innovations, such as information technology, have facilitated the compression of time and space and shaped forms of social resistance. In this scenario, the reduction of logistic costs in the production and distribution of commodities has become one of the fundamental conditions for the viability of large companies. This is more the case for industries that deal with highly perishable produce such as fresh food. Through an analysis of the perspectives of workers in the refrigerated cargo industry, the chapter illustrates the pressure that fall upon the individual routine of those involved in this field and the ensuing changes in this sector's operating standards. The study was conducted in the city of Recife, in the northeastern portion of Brazil.

Abstract

At the outset, though, and before brief summaries of each of these cases are presented, it is important to underscore two key points that guide the organization of the entire volume. First, capital mobility is a complex phenomenon that assumes various forms as different types of capitals move at different velocities. Second, capital mobility is a necessary and irreplaceable component of capitalism. As for the first aspect, we will consider three types of capital: financial capital, productive capital, and labor. Obviously, these three forms of capital are endowed with different features that affect their behaviors and their ability to move through time and space. While all these three forms of capital share the common requirement that they need to be utilized in increasingly accelerated manners if capital accumulation had to expand, they also display tendencies that favor financial and productive capital and subordinate labor. If effect, the subordination of labor to financial and productive capital is one of the primary characteristics of globalization and one item that allowed the rapid expansion of capital accumulation over the last two decades.

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

Purpose

There is no consensus on the most effective way to foster entrepreneurship in educational institutions, and educational policies on entrepreneurial activity differ significantly amidst organizations and contexts. Thus, the objective of this research is to analyze influence of the college environment and entrepreneurial characteristics on the entrepreneurial intention of Brazilian high school/technical students.

Design/methodology/approach

The empirical research used partial least squares structural equation modeling (PLS-SEM) and a sample of 384 students of technical courses, such as Administration, Systems Development, Chemistry, Secretariat, among others.

Findings

The proposed model was validated, and the hypotheses were confirmed, proving suitable for high school/technical education. Assessing the high school environment with this model can help determine each organization's strengths and weaknesses and, indeed, the impacts on the ecosystems in which it operates. The results of the multi-group analysis indicate differences concerning the courses as well.

Research limitations/implications

The main limitations involve non-probabilistic sampling procedures and the collection having been carried out with a single cross-section.

Practical implications

For managers and teachers, this article presents indicators to qualify the activities of the educational environment, considering teaching activities, extracurricular activities, fairs, actions of teachers and students, among other initiatives.

Social implications

The article contributes to high school managers, particularly in technical schools, so that they understand the factors that influence the profile and entrepreneurial intention of students; in other words, something that can impact the lives of thousands of students, teachers and the community itself.

Originality/value

This research presents a novel analysis of the antecedents that drive student entrepreneurship in an underexplored educational context in a developing country. The results show the necessary conditions for technical schools to foster entrepreneurial activity, feeding innovation ecosystems with entrepreneurial talent.

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 review aims to identify the determinants of voluntary disclosure of corporate social performance (CSP) and to analyze and consolidate previous quantitative studies to identify the theoretical perspectives and the variables used in measuring the determinants of CSP disclosure (CSP-D).

Design/methodology/approach

A literature review of articles published from 1987 to 2015 was conducted using the three databases, Ebsco, ISI and Jstor, with CSP-D as the dependent variable. The goal was to identify the theoretical perspectives underlying the studies and the independent variables.

Findings

The literature revealed a set of variables and their general measures, but the consensus confirmed that there was no single explanation for what determined CSP-D. The published theories that support a relationship between CSP-D and its determinants are legitimacy, institutional, stakeholder, agency and voluntary disclosure theory.

Originality/value

The results allowed us to identify the perspectives underlying the major theories and disclosed a set of factors considered by the literature as the ones that influence CSP-D. This information will be useful for researchers interested in developing their own studies on CSP-D because it presents the evolution of CSP-D factors over time and organizes the findings of multiple studies developed since the emergence of the theme.
