Firefighters are daily confronted with adverse, unpredictable and demanding situations. It is a dangerous profession that puts firefighters at risk of developing burnout. Although the literature has already identified personal and work-related factors of burnout, the examination of specific factors explaining burnout among volunteer and career firefighters is still needed. The purpose of this study is to investigate the explaining role of personal and work-related factors on volunteer and career firefighters’ burnout.

A nonrandom convenience sample of 250 firefighters (67% volunteer; M_age = 31.88) completed a sociodemographic questionnaire, the Oldenburg Burnout Inventory, the Proactive Coping Scale and a standard of living subscale item. Hierarchical multiple linear regression models were tested. Fisher’s criterion was considered, with p-values lower than 0.05 interpreted as statistically significant.

Personal and work-related factors accounted for 18% of volunteer and 31% of career firefighters’ variations in burnout. Personal factors offered a greater contribution explaining volunteer and career firefighters’ burnout. Still, variations in the role played by age, family responsibilities, proactive coping and satisfaction with standard of living on burnout were found among volunteer and career firefighters. Taking the work-related factors into account, working in rotative shifts constituted a risk factor for career firefighters’ burnout.

This study advances the understanding about the role of personal and work-related factors in volunteer and career firefighters’ burnout.

This study adds information about specific factors explaining burnout among voluntary and career firefighters. It deepens existing knowledge on variations in the role played by age, family responsibilities, work conditions, proactive coping and satisfaction with standard of living on the burnout of volunteer and career firefighters.

This study analyzes earnings management among Brazilian public firms during the 2016 Presidential Impeachment.

The sample comprises, as a treatment group, 721 firm-quarter observations relating to Brazilian listed firms. It also considers a control group of listed firms from Mexico, which were not affected by the exogenous shock analyzed (i.e. the 2016 Presidential Impeachment in Brazil). The firms' quarterly financial data cover the period between 2013 and 2018.

Considering several proxies related to earnings management by accruals, the main findings suggest a negative relationship between the 2016 impeachment event and the level of discretionary accruals, suggesting that Brazilian firms tended to reduce their earnings management levels during the impeachment process. The results are robust whether the control group is considered or not.

This study brings new empirical evidence to the literature on accounting information quality about the role of the economic and political environment in earnings management, especially in weak institution countries characterized by institutional voids and higher levels of corruption.

This paper aim to propose a methodological mapping approach for the evaluation of dissertations and theses of graduate programs in the area of environmental sciences in Brazil in relation to the UN sustainable development goals (SDGs).

The research is characterized as exploratory with qualitative/quantitative approach. The proposed model was developed as a computational algorithm with a pilot being adopted as a professional master in national network for teaching in environmental sciences (ProfCiAmb) comprising associated courses from nine Brazilian public universities. 230 dissertations completed between 2018 and 2020 were analyzed.

A total of 266 correlations were identified between the texts and descriptors of each SDG. Correlation values between 0.100 (minimum value – Vmin) and 0.464 (maximum value – Vmax) were observed. SDG 4 – Quality Education (Vmax = 0.399) and SDG 6 – Drinking Water and Sanitation (Vmax = 0.464) were those with the highest correlation values, followed by SDG 3 – Health and Well-Being (Vmax = 0.299) and SDG 17 – Partnerships and Means of Implementation (Vmax = 0.249).

The construction of the computational algorithm provided consistent quantitative analyses with potential to contribute to the improvement of the multidimensional evaluation of graduate studies, as well as to support public policies related to teaching and research and strategic planning of the programs.

The relevance of this study lies in the creation of a model that involves the creation of metrics and tools regarding the impact of graduate studies on society.

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).

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.

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.

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.

The purpose of this study is to address the extended travel time caused by dwelling time at stations for passengers on traditional rail transit lines. To mitigate this issue, the authors propose the “Non-stop” design, which involves trains comprised of modular vehicles that can couple and uncouple from each other during operation, thereby eliminating dwelling time at stations..

The main contributions of this paper are threefold: first, to introduce the concept of non-stop rail transit lines, which, to the best of the authors’ knowledge, has not been researched in the literature; second, to develop a framework for the operation schedule of such a line; and third, the author evaluate the potential of its implementation in terms of total passenger travel time.

The total travel time was reduced by 6% to 32.91%. The results show that the savings were more significant for long commutes and low train occupancy rates.

The non-stop system can improve existing lines without the need for the construction of additional facilities, but it requires technological advances for rolling stock.

To eliminate dwelling time at stations, the authors present the “Non-stop” design, which is based on trains composed of locomotives that couple and uncouple from each other during operation, which to the best of the authors’ knowledge has not been researched in the literature.

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.

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.

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.

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

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

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.

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

The financial policies of the modern world corporations and their investment decisions are generally considered as interrelated because the agency problems, associated with the debt level and its maturity structure, give rise to incentives for overinvestment or underinvestment. The present study empirically investigates the linkage between debt maturity structure and firm investment in a financially constrained environment, using Pakistan as a case study, to determine how the institutional environment in which firms operate affect these decisions and their linkage.

The empirical analysis is carried in a panel data setting using panel regression models as the baseline methods. Moreover, generalized methods of moments (GMM) estimators are used, coupled with the instrumental variables approach, for robustness and improving the efficiency and consistency of estimates.

Results suggest that firms rely more on short financing in Pakistan. Thus, given the capital structure which is characterized by higher proportion of short-term financing, the higher level of leverage is less likely to cause underinvestment problem. However, the underinvestment problem do persists in the firms that have higher portion of long-term debt. These findings imply that the debt-overhang problem may persist even in the financially constrained environments where attractive investment opportunities are limited, and long-term financing is difficult to acquire.

This study contributes to the literature by revealing how corporate investment and financing decisions and their linkage is influenced by the institutional environment of the less developed countries which is characterized by underdeveloped financial markets, inefficient legal system and weak investor protection system.

This study aimed to analyze the strategies and challenges related to technology transfer (TT) in technology transfer offices (TTOs), specifically regarding actions to offer technologies in their portfolios.

The qualitative research used a multiple case study based on interviews with TTO managers from seven Brazilian public Science and Technology Institutions (STIs): University of São Paulo (USP), State University of Campinas (UNICAMP), Paulista State University (UNESP), Federal University of Minas Gerais (UFMG), Federal University of Paraná (UFPR), Federal Technological University of Paraná (UTFPR) and Oswaldo Cruz Foundation (FIOCRUZ).

STIs that invest more resources in their portfolio’s active offering and marketing are more successful in TT than STIs with a passive strategy. Although this active strategy has grown in importance, there is a disparity among Brazilian TTOs as some are still passive in commercializing their intellectual property. This research also highlights the need for clear policies to overcome obstacles related to legal uncertainty for researchers who wish to undertake projects as entrepreneurs using the intellectual property of STIs.

The results of this study cannot be generalized since its conclusions are limited to the studied institutions. However, the outcomes indicate some interesting matters for managers of STIs, public policymakers and TT researchers.

Literature on marketing and innovation related to TT between research institutions and companies in developing countries is still limited. Thus, this research contributes to generating knowledge in the field and improving TTOs.

The purpose is to market a reinterpretation of Brazilian economic history highlighting the importance of non-tradable goods to understand major historical developments such as the lack of industrialization in the mining boom; the rise and contribution of industries to development in the early 20th century; indexation as hyperinflation in the late 20th century; growth and cycles in the early 21st century.

Section 2 introduces analytical perspectives on the relationship between non-tradables, transport costs and external shocks. Section 3 presents a historical overview of the gold and coffee cycles in the Brazilian economy, which highlights the crucial role played by transport costs in the genesis of industrialization. Thus, in a more precise way, industrialization was not an import substitution process but the substitution of non-tradables by the domestic tradable manufactures.

Section 4 shows that Brazilian statistical records and historiography disregard this characterization and, to that extent, underestimate economic growth in the primary export phase (1872–1920) and overestimate growth rates in the industrialization period (1920–1940). Section 5 shifts to the end of the 20th century to analyze the relationship between non-tradables, indexation and hyperinflation. Section 6 concludes with a brief discussion of the role played by the terms of trade and non-tradables in the unfolding of the 2014 economic crisis.

Distance from international markets and a continental geographic size made transport costs in Brazil historically prohibitive: the relevance of non-tradables in the Brazilian economic history. While the theme is not new, it seldom received proper attention in the historiography.

Social factors can shape economic decisions. Corporate governance (CG) studies and guidelines usually neglect that the chief executive officer (CEO) and board members may be socially tied. This study investigates the effects of social ties between the CEO and board members on earnings management (EM).

The authors run a series of regressions using a sample of Brazilian companies listed on the Brazilian Stock Exchange [B]³ between 2011 and 2017 to assess the effect of the social ties between the CEO and board members on EM using a social ties index. The authors also employ five robustness tests to verify the consistency of results, including alternative proxies of EM and social ties and an estimation using fixed effects.

After developing and computing a social ties index between the CEOs and members of the board of directors (BD) and the fiscal council (FC), the study’s findings indicate that a significant level of social ties between the CEO and BD has a negative impact on EM. However, for FC members, the authors found non-significant results.

Unlike previous studies, the authors built a social tie index (STI) from five elements of social ties assessed in an environment with a two-tier board system. Results show that elements of social interactions and personal relationships can benefit the company, as a CEO's level of social ties with the BD reduces EM practices.
