The present study aims to examine the mediating role of (in)voluntariness in teleworking in explaining the relationship between employees’ fit to telework and work well-being (i.e. work engagement and exhaustion).

A cross-sectional survey design was used in this study. The sample comprised 222 individuals performing telework in Portugal. Statistical analyses employed were descriptive statistics, Pearson’s correlation, confirmatory factor and structural equation analyses, and mediation analysis using Hayes Process macro.

The findings confirmed the hypothesis that employees’ fit to telework raises the voluntariness in telework and decreases involuntariness in telework. However, contrary to expectations, no significant relationships were found between voluntariness in telework, work engagement and exhaustion. Yet, involuntariness in telework showed a significant role in decreasing work engagement and increasing workers’ exhaustion. The mediating role of involuntariness in telework was confirmed in explaining the relationship between employees’ fit to telework and exhaustion.

Managers in global firms can draw from the results to understand how employees’ fit to telework directly and/or indirectly contributes to work well-being and develop human resource (HR) management practices aiming to increase employees’ fit to telework.

Although teleworking is already studied, to the best of the authors’ knowledge, no studies have analyzed the same conceptual model employees’ fit to telework, (in)voluntariness in teleworking and work well-being.

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.

Este estudo tem como objetivo estudar a relação entre a sobrequalificação, a empregabilidade, a insegurança no trabalho percebidas e satisfação das necessidades psicológicas globais, considerando o papel moderador dos grupos etários.

Foi utilizado neste estudo um desenho de pesquisa transversal com uma amostra de 350 indivíduos.

A sobrequalificação percebida, a empregabilidade percebida e a insegurança no trabalho percebida estão, em geral, significativamente relacionadas com a satisfação das necessidades psicológicas globais. No entanto, essas relações diferem entre as faixas etárias. Ou seja, para os indivíduos mais jovens, foi observada uma relação negativa entre a perceção de sobrequalificação e a satisfação das necessidades psicológicas globais, e para os indivíduos de meia-idade, a empregabilidade percebida está positivamente relacionada à satisfação das necessidades psicológicas globais, enquanto a insegurança no trabalho percebida e a sobrequalificação percebida estão negativamente relacionadas à satisfação das necessidades psicológicas globais. Finalmente, para os indivíduos mais velhos, a insegurança no trabalho percebida e a sobrequalificação percebida estão negativamente relacionadas à satisfação das necessidades psicológicas globais.

The main aim of this paper is to illustrate the importance of avoiding Whig interpretations in historical research. It does so by highlighting examples of what may occur when this is not done. The paper also aims to promote interdisciplinarity, in the form of working with those from other disciplines, as a means to avoid this occurring.

This paper includes an in-depth study of the bookkeeping and financial reporting of two 18th century Portuguese state-sponsored companies using archival sources. The companies were selected because of conflicting insights across disciplines concerning the quality of their bookkeeping and financial reporting – historians have been very critical, while accounting historians have seen little wrong. These differences of opinion have never previously been investigated. The authors demonstrate how information was distributed among the account books and other records of the two companies. The approach adopted enabled a reader to fully understand the recorded economic events. The authors also present and explain the procedures, criteria and accounting terminology used in their annual reports.

This paper demonstrates how easy is to inadvertently adopt a Whig interpretation of accounting history when the focus of interest is something of which the principal researcher has insufficient understanding or expertise. It also illustrates how important it is to embrace interdisciplinarity by working with those from other discipline to avoid doing so.

The conclusions from the case study are company-specific and cannot be generalised beyond those companies. However, the implications of this study go beyond the companies in its illustration of the importance of fully understanding historical evidence within its own context.

This paper unveils primary archival sources never previously presented in the literature. It also contributes to the literature by providing an evidence-based justification for the calls previously made to accounting historians to study accounting in its social context and engage with historians from other disciplines.

To meet the consumer demand for a healthier diet, this study emphasizes the feasibility of using vegetable oil gelled emulsions in low-fat industrialized burgers with high contents of polyunsaturated fatty acids (PUFAS). Commercial canola and olive oils have been tested as a relatively inexpensive source of PUFAS.

Beef burgers were reformulated by replacing (0, 25, 50, 75 and 100%) pork back-fat with two carrageenan gelled emulsions of vegetable oils (canola and olive oil). The technological characteristics, sensorial properties and the fatty acid profile of reformulated burgers were evaluated.

Moisture content and cooking loss increased and fat and protein contents reduced with higher replacements. Oxidative stability was not affected and replacements of up to 75% did not affect the burger's acceptance. A total fat content reduction of 40% was achieved in burgers with 100% back-fat replacement, improving its nutrient value by increasing the ω−6/ω−3 ratio and decreasing the saturated fatty acids content (in 47%) and the atherogenic (from 0.61 to 0.22) and thrombogenic (from 1.29 to 0.65) indexes. Replacing up to 75% with canola oil gelled emulsion is a promising approach in the design of healthier industrial low-fat burgers.

Due to the association of some diseases with the consumption of products rich in saturated fat, the industry looks for alternatives not only to reduce the fat content but also to modify the fatty acid profile in meat products. This study further confirms the possibility of using carrageenan gelled fat replacer in industrialized burgers formulated with meat and other ingredients/additives commonly used to provide economic benefit. Also, confirms the feasibility to use commercial vegetable oils with relatively cheap cost than ω−3 rich oils as the oil phase in the gelled emulsion.

This paper aims to identify and analyze the agtech classification and categorization systems in the Brazilian context.

The systematic literature review (SLR) was carried out according to the protocol of Kitchenham and Charters (2007). The classification systems found in literature were evaluated using the thinking aloud protocol, as proposed by Ericsson and Simon (1993). The responses obtained were evaluated through lexicographic analysis, described by Bécue-Bertaut (2019) and content analysis, described by Bardin (2011).

SLR identified four agtech classification systems. The model proposed by Dias, Jardim, and Sakuda (2019) was the one with the highest adherence to classify Brazilian agtechs. From the analysis of the systems found in literature, the authors proposed a new categorization model of agricultural startups (agtechs).

The study has limitations in relation to the theoretical and empirical validation of the model proposed by the authors. This limitation can be the subject of subsequent research.

The SLR study considers the evolution of the classification systems of a new agribusiness reality, the agtechs. In addition, there is a practical contribution in proposing a new classification system that attempts to address some of the limitations found in previous studies.

Agtechs are startups focused on developing solutions for agriculture and have shown a significant increase in recent years. However, there are few studies focused on this type of company. Even rarer are the studies that seek to classify and categorize them. The present work opens the horizon for future studies focused on this new reality.

2D laser rangefinders (LRFs) are commonly used sensors in the field of robotics, as they provide accurate range measurements with high angular resolution. These sensors can be coupled with mechanical units which, by granting an additional degree of freedom to the movement of the LRF, enable the 3D perception of a scene. To be successful, this reconstruction procedure requires to evaluate with high accuracy the extrinsic transformation between the LRF and the motorized system.

In this work, a calibration procedure is proposed to evaluate this transformation. The method does not require a predefined marker (commonly used despite its numerous disadvantages), as it uses planar features in the point acquired clouds.

Qualitative inspections show that the proposed method reduces artifacts significantly, which typically appear in point clouds because of inaccurate calibrations. Furthermore, quantitative results and comparisons with a high-resolution 3D scanner demonstrate that the calibrated point cloud represents the geometries present in the scene with much higher accuracy than with the un-calibrated point cloud.

The last key point of this work is the comparison of two laser scanners: the lemonbot (authors’) and a commercial FARO scanner. Despite being almost ten times cheaper, the laser scanner was able to achieve similar results in terms of geometric accuracy.

This work describes a novel calibration technique that is easy to implement and is able to achieve accurate results. One of its key features is the use of planes to calibrate the extrinsic transformation.

This research aims at studying the influence of a classroom’s inner environmental conditions on undergraduate students’ performance using an experimental methodology.

The Uchida-Kraepelin test (U-K test) was applied to measure the performance of a group of 47 students in a selected classroom that was arranged according to the following experimental conditions: air-conditioning on, and doors and windows closed (D1); doors and windows open, and air-conditioning off (D2); air-conditioning off, and doors and windows closed (D3). After completing the tests, questionnaires were distributed to evaluate the students’ assessment of each set of environmental conditions.

On-site measurements of humidity and carbon dioxide levels stress the importance of ensuring good natural ventilation through open doors and windows, independently of whether the air-conditioning system is operated or not. Also, the authors find that the students’ self-assessment regarding the inner environmental conditions for each studied set was entirely accurate, with set D3 being assessed as the worst. The U-K test scores for each environmental set did not show statistically significant differences, which means that, in the studied conditions, the student’s performance in the tests was not affected by the inner environmental conditions.

There is a direct relationship between the building’s indoor conditions and an occupant’s health. Factors such as poor maintenance, bad indoor environmental quality (IEQ) and building age will worsen the building’s condition and negatively impact the occupant’s health. Educational buildings with poor IEQ can reduce the concentration and performance of occupants.

School is an important place to help students grow in their various capabilities. They spend approximately 30% of their daily lives in schools for their educational activities. Since most of their activities are performed indoors, indoor environmental attributes, such as light, heat, air and sound, should be maintained as required. In general, schools are not thermally comfortable. The extreme thermal environment of classrooms affects students’ concentration. Thermal discomfort may also cause irritation. In addition to reduced concentration, such an environment could also cause tiredness, sluggishness and health problem.

Despite the importance of the issue, scientific investigations of the correlations between students’ performance and the quality of scholar buildings’ inner environmental conditions are still relatively recent. In this context, this research further explores the effect of a classroom’s different environmental inner conditions on the performance of undergraduate students at a university in São Paulo/Brazil.

The civil construction industry has vital importance to Brazil's economy. However, this sector is also responsible for the environmental impacts. Governments have been taking measures aiming to mitigate these impacts. Among these, the elaboration and implementation of civil construction solid waste management plans can be highlighted. However, these plans still lack standardizations and tools for their evaluation. Environmental indicators proposal for construction solid waste management plans assessment is presented to verify the adhesion of these to environmental laws, technical standards and green building certification systems recommendations.

The construction solid waste management plans of three construction works were evaluated by the proposed indicators to verify the procedures related, generating, in the end, a scale between 0 and 5. After that, plans were compared with each other.

The proposed indicators have made possible the evaluation of the environmental practices performed for three different construction works. By the proposed indicators, the environmental practices were compared to technical standards and legislation suggested procedures.

As a contribution, the evaluation proposal presented may help the construction industry as well as the public authority to evaluate the construction solid waste management plans currently elaborated, so that these can offer a quality improvement and more effective environmental measures.

Methodologies that guide the evaluation of construction solid waste management plans can be beneficial for the construction companies, which can improve the quality of the plans elaborated internally and verify the effectiveness of the plans elaborated by specialized consultancies. In general, most of the construction solid waste management plans are prepared with the purpose of only complying with the legislation, more specifically of the National Council for the Environment, Resolution 307/2002.

This study aims to investigate how different executive compensation structures were related to the performance of firms.

This study was based on a sample of companies with the highest standards of corporate governance listed on the Brazilian Stock Exchange. We adopted the multiple correspondence analysis followed by the hierarchical cluster analysis to propose a typology defined by fixed and variable components of the executive compensation and multiple firm performance indicators.

The analysis produced three clusters, which were submitted to robustness tests, highlighting that companies used the compensatory incentives in striking distinct ways as governance mechanisms. The study found a positive relationship between the performance of companies and the variable incentives of executive compensation, especially the long-term incentive, as well as a negative relationship between the performance of firms and the fixed component of the compensation structure.

This research, whose sample was based on an emerging market, adds empirical evidence to the literature. However, future studies are invited to address the relationships between executive compensation structures and firm performance in other markets, as well as to examine these relationships in companies with distinct levels of governance.

This study provides insights on how the incentive structure can be adopted as an efficient governance mechanism, especially for companies in emerging markets.

The main novelty of this paper is that the methodological strategy used here enabled the authors to discriminate distinct executive compensation structures and establish a relationship between these compensation structures and different types of performance indicators.
