Abstract

Purpose

In this paper a model for the prediction of the failure strain of fiber reinforced polymer (FRP) sheets is proposed, based on a significant database consisting of results reported in the literature for concrete columns with circular cross-section confined with carbon, glass and aramid fiber reinforced polymers. This study aims to analyze the aforementioned model.

Design/methodology/approach

Significant experimental research on the confinement of columns externally wrapped with FRP has been carried out in the last decades. Several models of confined concrete have been proposed using different approaches for the prediction of the failure strain of FRP sheets. The majority of those proposals were developed to be simple, thus significant differences with experimental results can be found.

Findings

The results of a total of 572 specimens were considered. Statistical analysis was used to derive a regression model, which relates the outcome to a set of predictors of interest using linear assumptions.

Originality/value

The proposed model is shown to be more accurate than other proposals found in the literature.

Abstract

The objective of this chapter is to outline an integrating picture of the situation, representativeness, contradictions, and challenges that the treatment of diversity assumes in Brazilian society and in its organizations. The aim is to reply to the research question: “How are public policies and organizational practices constructing ways of inserting and valuing the diversity of Brazilians?” We provide a brief background of the changes in the global and Brazilian contexts over the last few decades and analyze the demographic data presented in the 2010 Census and in studies on diversity that were published in the main periodicals in the Administration area in Brazil, between 2000 and 2014 with regard to the segments most widely studied in the academic literature: Afro-descendants, homosexuals, the elderly, Indians, women, and people with a disability. The conclusion reached is that, in a short period of time, Brazil has made great strides in constructing the mechanisms and legal devices for recognizing the rights of its diverse population and that private companies are in the initial stages of introducing diversity programs.

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.

设计/方法/途径

本篇观点论文是巴西前沿旅游学者们思考的集合, 其中大多数的学者是巴西旅游发展国际研究院ABRATUR的成员。这篇论文使用了诸如政府工作报告的二手数据和学术文献来支撑文章观点。其中涉及的与旅游相关的主题包括经济学, 政策和规划, 市场营销, 交通, 自然旅游, 烹饪学, 酒店, 教育等等。

目的

与巴西大多数旅游研究的出版物不同, 本文提供了一个重要且全面的视角。文章重点分析了从2000-2009年的旅游业主要发展状况, 同时考虑了阻碍旅游业发展的长期结构性问题。尽管此观点论文涉及巴西, 但在世界许多国家都可以发现非常相似的问题。

结果

巴西已经错失了作为国际知名旅游目的地的几个独特机会。二十世纪九十年代以来, 因为政治动荡, 暴力和腐败对旅游业的影响, 支持区域旅游业发展的努力仅仅取得了有限的成功。各级政府之间缺乏协调方式, 旅游数据短缺和长期的跨政府营销活动等因素, 已经意味着巴西在二十一世纪前十年已经错失了将自己在全球市场中确立为领先旅游目的地的几个重要机会。

创新/价值

这篇来源于一些巴西学术旅游届的领头羊的独特观点论文概述了从2000年到2019年巴西旅游业发展的关键问题。本文介绍了那些已经阻碍南美洲最大旅游国家潜在旅游业贡献的重要事项。尽管这些事项可能是巴西独有的, 但是其中许多问题与其他新兴的(民主的)国家也没有什么不同。我们提供了一些公共政策和技术建议, 以支持旅游业向2030年议程迈进。

Diseño/metodología/enfoque

Este artículo de opinión es una combinación de reflexiones de destacados académicos brasileños del turismo, la mayoría miembros de ABRATUR, la Academia Internacional para el Desarrollo de la Investigación en Turismo en Brasil. Se utilizan fuentes secundarias (por ejemplo, informes gubernamentales) y literatura académica para respaldar este artículo. Los temas relacionados con el turismo que se tratan en este documento incluyen economía, política y planificación, marketing, transporte, turismo basado en la naturaleza, gastronomía, hotelería, y educación, entre otros.

Propósito

A diferencia de la mayoría de las publicaciones académicas sobre el turismo en Brasil, este artículo ofrece una perspectiva global e integral. Al analizar los desarrollos clave y centrarse en 2000–2019, este documento también considera problemas estructurales de larga data que obstaculizan el desarrollo del turismo. Aunque este documento trata de Brasil, se pueden identificar problemas muy similares en muchos otros países del mundo.

Resultados

Brasil ha perdido varias oportunidades únicas para colocarse como un destino de renombre internacional. Los esfuerzos realizados desde la década de 1990 para apoyar el desarrollo del turismo regional solo han logrado un éxito moderado debido a que la inestabilidad política, la violencia y la corrupción han impactado al turismo. La falta de un enfoque coordinado entre los distintos niveles de gobierno, la escasez de datos turísticos, una campaña de marketing supra gubernamental a largo plazo, entre otros factores, han significado que Brasil haya perdido varias oportunidades críticas en la década de 2010 para establecerse como un destino turístico líder en el mercado global.

Originalidad/valor

Un artículo de opinión único de destacados expertos académicos en turismo en Brasil, que ofrece por primera vez una visión general de los problemas críticos del desarrollo desde la década del 2000. El documento presenta asuntos que han obstaculizado las posibles contribuciones del turismo a la nación más grande de América del Sur. Si bien estos asuntos pueden ser específicos de Brasil, muchos de estos desafíos no son diferentes a los de otras naciones (democráticas) emergentes. Ofrecemos diversas recomendaciones técnicas y de políticas públicas para impulsar el desarrollo turístico hacia la agenda 2030.

Abstract

When examining anecdotal evidence of migration processes, from historical and geographical perspectives, stories of individual immigrants that became successful entrepreneurs in the host country are commonplace. These narratives help individualize and romanticize the usually crude statistics of the increasingly common population movements across political borders. They also serve a number of purposes within the ethnic community, most of them associated with the creation and nurturing of the group's social capital. This critical ethnic resource has been consistently shown to provide significant benefits to immigrant communities, particularly in environments with higher levels of perceived risk (e.g., Portes, 1998; Martes & Rodriguez, 2004).

Abstract

Purpose

The research outlined in this paper highlights the importance of certain factors related to primary health care buildings’ physical environment, such as the facility size, the functional efficiency, and the health planning of public areas in the health centers to improve the architectural space of health facilities.

Design/methodology/approach

This study was performed using a mixed method. Data collection was carried out through observational research and descriptive analysis in six primary health care facilities in Salvador and Lauro de Freitas, Brazil.

Findings

Based on this study’s results, facility capacity, functional efficiency and space accessibility have been considered the facilities’ main problems in the investigated context. The impact of the users’ perspective on healthcare facilities was assessed for each of these three criteria to verify the results obtained. Furthermore, most of the parameters were not satisfied, as the buildings analyzed had defects in their physical environment. Therefore, it is necessary to review and pay more attention to the architecture of these cities’ primary health care units.

Originality/value

The present study addresses the architectural environment design in Brazil’s healthcare facilities, which still have gaps. Improving the physical space of a health center ensures that the approach used in this research also applies to other health centers in similar contexts. The awareness that space’s activities and configurations will change according to each territory examined will open up so many investigation worlds.

Abstract

Purpose

The quality of components under fused filament fabrication (FFF) is related to the correct filament spacing and bonding of successively deposited layers and is evaluated mainly by scanning electron microscopy (SEM). However, it is a destructive technique and real-time evaluation is not possible. Optical coherence tomography (OCT), on the other hand, is an optical method that acquires cross-sectional images non-invasively and in real-time. Therefore, this paper aims to propose and validate the use of OCT as a non-destructive quality evaluation tool for FFF using Polylactic Acid (PLA) filaments.

Design/methodology/approach

PLA three-dimensional (3D) printed samples were made in a variety of nozzle temperatures and mesh spacing. These samples were fractured in liquid nitrogen and inspected using SEM (as a gold standard) to evaluate dimensions and morphology, then the samples were evaluated by OCT in the same area, allowing the results confrontation.

Findings

Our results indicate a good correlation between OCT and SEM for the dimensional assessment of layers. When the filament was extruded in lower temperatures, the OCT images presented sharply defined interfaces between layers, in contrary to higher nozzle temperatures, denoting better fusion between them. However, higher extruding temperatures are incurred in greater deviations from nominal dimensions of the mesh. Finally, we demonstrate the advantage of a full 3D tomographic reconstruction to inspect within a FFF sample, which enabled the inspection of “hidden” information, not visible on a single cross-sectional cut.

Originality/value

This paper proposes OCT as a novel and nondestructive evaluation tool for FFF.

Abstract

The international literature on the impacts of globalization on large cities has insistently pointed to the increase in residential segregation. Three mechanisms have been identified as the causes of this phenomenon: globalization, which by disseminating neoliberal ideas throughout the world, generated changes in the regulatory models and paradigms that guide urban policy; institutional reforms toward market liberalization and the property and housing market were undertaken in various countries; real estate prices became the central mechanism for distributing the population throughout the city, reinforcing income inequality as the determinant of urban spatial organization. At the same time, privatization exacerbated the growing inequality of access to the services and infrastructure that ensure urban well-being, especially with regard to quality. The wealthier areas, where those with greater purchasing power concentrate, have at their disposal an abundant supply of goods and services, whereas the areas populated by the poor are supplied with inferior goods and services. Further, globalization caused structural changes originating in the transformation of the productive base of the cities, creating trends toward social polarization. The social structure of the great metropolises is no longer represented by a pyramid, and is expressed instead by an hourglass where the middle positions narrow while the extremities widen. Simultaneously, there has been an increase in the distance between the average incomes of the higher and lower strata.

Abstract

Purpose

This paper aims to analyze green human resource management's (GHRM’s) relationships with corporate social responsibility (CSR) and customer relationship management in Brazilian companies.

Design/methodology/approach

A sample of 142 companies – from the electro-electronics, mechanical metals, packaging, footwear and plastics industries – was examined using the partial least squares method.

Findings

The results reveal that GHRM practices positively influence CSR practices, which act as a moderating construct to positively influence customer relationship management.

Research limitations/implications

The results cannot be generalized due to the non-probabilistic sampling used; however, the results meet the requirements of the statistical methodology.

Practical implications

These findings contribute to business managers' decision-making, as they demonstrate that organizations must develop a consistent culture focused on social and environmental issues. This also reveals that the human resources field can contribute to developing a socially correct company, with the subsequent possibility of satisfying customers to retain and create customer loyalty.

Social implications

The results show that for a company to be sustainable from an economic, social, and environmental perspective, the involvement of human resource management is fundamental.

Originality/value

This paper contributes to academia by presenting a new theoretical model, tested using a sample of Brazilian companies, which illuminates GHRM as an area still under development.

Abstract

In this article, we discuss the issue of the right to education of young children, focusing on the Institution of Early Childhood Education (EIC in Portuguese), of views with legal markers and educational indicators of a Brazilian State. From a research that approached Early Childhood Education (EI in Portuguese) in settlements of the Landless Rural Workers Movement (MST in Portuguese) and making use of the Bakhtinian framework we highlight the processes of inequality that devastate childhood in the rural settings. The data reiterate the need to not only combat the logics of precariousness that affect the service given but also to guide the specificity of Children’s education field, within a framework of the effectiveness of primary school attendance. Hence, we call one’s attention to the debate of the ways of setting up institutions, with a view to serving children, urging the regulations related to the right to education, particularly, the right to Early Childhood Education in the peasant’s context, particularly in settlements.
