Abstract

Purpose

In the analysis of structures in a fire situation by simplified and analytical methods, one assumption is that the fire resistance time is greater than or equal to the required fire resistance time. Among the methodologies involving the fire resistance time, the most used is the tabular method, which associates fire resistance time values to structural elements based on minimum dimensions of the cross section. The tabular method is widely accepted by the technical-scientific community due to the fact that it is safe and practical. However, its main criticism is that it results in lower fire resistance times than advanced thermal and thermostructural analysis methods. The objective of this study was to evaluate the fire resistance time of reinforced concrete beams and compare it with the required fire resistance time recommended by the tabular method of NBR 15200 (ABNT, 2012).

Design/methodology/approach

The fire resistance time and required fire resistance time of reinforced concrete beams were evaluated using, respectively, numerical models developed based on the finite element method and the tabular method of NBR 15200 (ABNT, 2012). The influence of the following parameters was investigated: longitudinal reinforcement cover, characteristic compressive strength of concrete, beam height, longitudinal reinforcement area and arrangement of steel bars.

Findings

Among the evaluated parameters, the covering of the longitudinal reinforcement proved to be more relevant for the fire resistance time, justifying that the tabular method of NBR 15200 (ABNT, 2012) being strongly and directly influenced by this parameter. In turn, more resistant concretes, higher beams and higher steel grades have lower fire resistance time values. This is because beams in these conditions have greater resistance capacity at room temperature and, consequently, are subject to external stresses of greater magnitude. In some cases, the fire resistance time was even lower than the required fire resistance time prescribed by NBR 15200 (ABNT, 2012). Both the fire resistance time and the required fire resistance time were not influenced by the arrangement of the longitudinal reinforcements.

Originality/value

The present paper innovates by demonstrating the influence of other important design variables on the required fire resistance time of the NBR 15200 (ABNT, 2012). Among several conclusions, it was found that the load level to which the structural elements are subjected considerably affects their fire resistance time. For this reason, it was recommended that the methods for calculating the required fire resistance time consider the load level. In addition, the article quantifies the security degree of the tabular method and exposes some situations for which the tabular method proved to be unsafe. Moreover, in all the models analyzed, the relationship between the span and the vertical deflection associated with the failure of the beams in a fire situation was determined. With this, a span over average deflection relationship was presented in which beams in fire situations fail.

Abstract

The production of news through artificial intelligence (AI) is a reality in many countries, including the United States, where two leading companies in this area are based. The purpose of this explanatory bibliographic research is to discuss who or what should bear the ethical responsibility for automated writing in a newsroom, considering that codes of ethics address only the conduct of people. This chapter compares the Code of Ethics of the National Federation of Brazilian Journalists with the code used in the United States and highlights examples of news released with incorrect information, produced by algorithms, and published by US news organizations. Facing the current informational scenario, the ethical responsibility of the automated news must be attributed to the media, represented in the figure of the editor. Such a conclusion is motivated by the fact that neither the algorithm nor the person who developed it takes part in the decision-making process of publishing an article or not.

Abstract

What are the academic experiences of senior professors in the field of public relations (PR) at the Brazilian universities? This chapter proposes the advance of knowledge on the theoretical framework of contemporary liberal feminism by refining the previous theoretical and methodological publications. This theoretical lens prevails in earlier works, with empirical studies grounded in industry and corporate environments – mainly done by researchers from the United Kingdom, North America and Scandinavia, while PR feminist postmodernism appears in European literature – all scarce in Brazil and Global South (Latin America and African nations). Moreover, studies applying female or male PR scholars in university settings are rare in national and international literature. Hence, we gathered data and analysed narratives from seven senior female PR professors from Brazil, using an interpretative qualitative approach. Thus, this chapter about the female PR academic experiences and everyday practices highlights the starting point for an onto-epistemological discussion to understand the liberal feminist educational-based context in a Latin American country. Henceforth, two conceptual-practical dimensions – feminist PR competence and feminist PR performance – along with three methodological recommendations are presented for enhancing the contemporary liberal feminism theme as a robust research domain in PR and Strategic Communication agenda.

Abstract

Purpose

The purpose of this study is to examine how a group of special companies, i.e. highly acknowledged and awarded ones operating in Brazil handle the gender issue.

Design/methodology/approach

This investigation relies on historical analysis by addressing essentially a surface-level indicator (i.e. gender preferences). Rather, this study is grounded on data from the companies that were awarded as one of the best organizations to work for in Brazil by Época-Great Place to Work® Institute and Guia Você S/A lists (between 2012 and 2016). As a result, four organizations were selected, that is, the most representative examples of gender doing.

Findings

Overall, it found that the glass ceiling is apparently breaking down within at least some germane Brazilian organizations. However, data suggest that other sorts of institutional discrimination may be taking place, i.e. the one in which a feminist mindset may be permeating an organization or even a whole business sector. Under such a scenario, male workers will likely have only a few opportunities.

Research limitations/implications

The sample size of this study does not permit that the results be generalized. In addition, data were elicited from only a specific cohort of companies.

Practical implications

It was found no substantial evidence that these organizations are making strides toward at least mitigating the effects of their gender unbalance, although gender equality and, broadly speaking, diversity does not constitute a new management topic anymore.

Originality/value

Unlike other investigations, it encompasses a larger sample of companies, draws exclusively upon gender-based organizations and is grounded on multiple sources of information. Additionally, data revealed that gendered organizations may encompass different levels of salience.

Abstract

This chapter is born out of concern about the perception of the physical and symbolic place of the live-in housekeeper, both in socioeconomic, and historical terms, as well as the architectural and social dynamics of the home. An intersectional and teleological analysis of the intrinsic devaluation of paid social reproduction work is carried out, based mainly on gender, race, and class inequalities. Ultimately, the chapter tries to locate the position in which the maid finds herself in the domestic environment, both in family relationships and in the symbolism inherent to the concept of the maid’s room. Based on sociological, philosophical, and anthropological analysis, the ambiguous place of domestic workers becomes clearer, promoting a reflection on the very concept of family and household. Thus, the chapter proposes to achieve a hermeneutic dive into the experience of this working class, revealing a hierarchical system beyond the socioeconomic, but above all, of their subjectivities.

Abstract

Purpose

This study aims to analyze the relationship between telework and teleworkers’ characteristics and the work-nonwork conflict (WNWC) in the Brazilian context, investigating time spent in eight nonwork dimensions and the more affected dimensions.

Design/methodology/approach

The study was quantitative and descriptive. A survey was conducted with 299 professionals’ teleworking in Brazil. Data analysis was conducted through descriptive statistics, Pearson’s correlation and analysis of variance.

Findings

Results show diversified interests other than work and family among teleworkers, variation within the affected nonwork dimensions in the WNWC, and that teleworkers’ WNWC is negatively associated with time flexibility and manager support and positively associated with individual preference for segmentation as a boundary management strategy.

Research limitations/implications

The study highlights the need to include more nonwork aspects in telework studies to influence organizational practices. The main limitation is the nonprobabilistic sample.

Practical implications

Knowing more about teleworkers’ WNWC will help organizations improve lives by implementing practices and building a cultural environment that preserves nonwork time.

Social implications

The study reinforces demands from new family arrangements and an aging society: organizations have to prepare to have teleworkers who want or need to dedicate time to interests besides family or children.

Originality/value

It progresses towards a broad understanding of nonwork besides family to understand teleworkers’ WNWC.

The purpose of this paper is to analyze the prejudice and discrimination constructs through the lens of a transcendent knowledge concept.

Abstract

Purpose

The purpose of this paper is to analyze the prejudice and discrimination constructs through the lens of a transcendent knowledge concept.

Design/methodology/approach

The paper seeks to demonstrate that Spiritism or Spiritist Doctrine (SD) – regarded here as a source of transcendent knowledge – offers compelling arguments and provides suitable explanations (i.e. transcendent ontology) in relation to the issue of discrimination

Findings

Overall, this paper contributes to a better understanding of diversity and inclusive perspectives by examining the antecedents and consequences of discrimination through the insightful lens of SD tenets. In this sense, the findings suggest that the discriminators and prejudiced people may ironically pass through – as a result of the law of cause and effect – the same hard situations (i.e. ordeals or nightmares) – even though in their future lives – that they impose in their current victims to forcefully open their minds, support universal values, enhance their own feelings and spiritual intelligence.

Practical implications

Evidence presented here (although conceptually in nature) could be somewhat integrated into training sections of diversity management. At a minimum, it may encourage the shift of attitudes, revision of embedded values and reflections about the spiritual consequences to the perpetrators of discrimination against minorities.

Originality/value

Taken as a whole, the SD tenets prompt us to understand that the acts of prejudice, stereotyping and discrimination engender suffering for their perpetrators, even in their future lives (i.e. reincarnations). Broadly speaking, the SD principles compel us to consider transcendent knowledge even in the context of organizational life.

Abstract

Purpose

The article aims at analyzing the social representations of retirement in two different groups of professors – pre-retired and retired – from a public higher education institution. The goal is to explore the experiences, reflections, beliefs, and attitudes originated from the transition to retirement.

Design/methodology/approach

The research, of exploratory and descriptive nature, was guided by the Social Representation Theory (SRT) and took a qualitative approach. 16 professors were interviewed, 8 in each group (pre-retired and retired professors), using semi-structured interviews that followed a script designed to discover the main aspects of the transition to retirement.

Findings

Three figurative cores were raised – the financial aspect, the centrality of work, and the will to continue contributing, and the unpreparedness for retirement – and testimonies have shown heterogeneous representations. The study observed that although relevant, the bonus for continued services is not the main determinant for professors to continue working in the university.

Originality/value

The results of this study indicate the need to treat retirement as a complex and multidimensional process, offering a fresh perspective on the social representations of retirement in the academic context. The use of the Social Representation Theory to explore these perspectives adds to the originality of the approach, highlighting the multifaceted nature of the retirement process in this specific professional group.

Abstract

Purpose

The career is a space where family and work lives amalgamate. The role of work for the individual, and the meaning of work within the culture, will determine the relevance of family. This study investigates CEOs' perception about conjugal family influence on career decisions, and it examines family factors.

Design/methodology/approach

Through a qualitative study, 22 Latin American CEOs who work for multinational firms were interviewed in a semi-structured way.

Findings

Not all career decisions were influenced by conjugal family. CEOs varied in the extent to which they considered their families when reflecting on their career decisions. Expatriation, joining or quitting an organization and change of area of work were found as those decisions perceived to be influenced by conjugal family. Family support, family structure and family demands and responsibilities were identified as the family factors involved. In spite of the role salience, family factors influenced some of CEOs' career decisions, in part, due to the cultural characteristics of the Latin American environment. The instrumental support of the extended family, as part of collectivist societies, was also evidenced.

Practical implications

A better understanding of the family influenced decisions and family factors involved may enhance individual career decision-making as well as organizational career management processes and public initiatives.

Originality/value

This study contributes to family and career literature, being the first one to explore the conjugal family influence upon CEOs' career decisions.
