This paper aims to further the discussion on Building Information Modelling (BIM) legal requirements, providing a framework with key energy parameters capable of supporting the Appointing Party in the definition of the Exchange Information Requirements (EIR) for a BIM project appointment. The EIR is described in ISO-19650–1:2018 as a fundamental step in the information delivery cycle.

A literature review on the topic of BIM energy analysis was completed to identify current knowledge gaps and support the need for the proposed framework. Afterwards, the framework was established based on the review findings and the authors’ domain knowledge. The applicability of the proposed framework was assessed through a case study, where several energy simulations were performed in three different design stages of the same BIM model.

This study identified a lack of standards and legislation capable of supporting the Appointing Party in the definition of energy-related BIM requirements. To this end, a new framework is proposed to mediate existing practices, linking prior knowledge with BIM’s new reality. The study showcases the applicability of the framework, identifying that the performance of different energy studies involves distinct Level of Development (LOD) requirements, which in turn have an impact on the modelling time and cost.

A BIM framework for the specification of information requirements in energy-related projects was developed to support the Appointing Party. The framework presents appropriate parameters for energy analysis in each design stage, as well as the suitable LOD for the BIM model.

The purpose of this paper is to develop and test control methods for real‐time automatic presser‐foot force control in industrial sewing machines. In this work, a closed‐loop controller that controls presser‐foot maximum vertical displacement is presented and compared to existing solutions that adjust force depending on sewing speed. Automatic force control can reduce problems such as stitch irregularity, stitch distortions and material damage, besides making material handling easier.

An electromagnetic force actuator was integrated in an industrial lockstitch machine. A computer‐based control system was designed implementing either speed‐variable force control, closed‐loop control, or emulating a traditional constant‐force system. Maximum presser‐foot displacement values were measured and analysed in relevant sewing situations, and seam quality was assessed.

Constant‐force control does not allow optimal force setting at all speeds. Speed‐variable force control is an improvement, but requires empirical setting of the speed‐force relation, not always assuring optimal operation. Closed‐loop control adapts force to the requirement of each sewing situation more precisely. Sewing quality is good and material handling is eased.

The actuator has to be optimised regarding response time and maximum force. Some aspects in the behaviour of the control system and actuator have to be further studied.

The proposed control system enables the automatic setting and adaptation of force to all sewing situations, making material handling easier at low speeds without compromising feeding performance at high speed. The closed‐loop controller may be used as a teach‐in system for speed‐dependent control.

This is the first prototype of a closed‐loop control system for presser‐foot force on a lockstitch sewing machine and the first comparative study of control methods for presser‐foot force control.

Though poverty is one of the consequences of the lack of education, this latter can be the solution to poverty, particularly when children and youngsters are prioritized in school. And in the fight against inequality, education for the development of human beings is the key, especially if we want to save children and adolescents in order to guarantee the future.

Improper levels or excess of iodine may present a greater risk to health, for this reason, this paper aims to assess the iodine content present in salt and estimate the iodine concentration in school meals in a Brazilian northeast region.

Six samples of different salt brands sold in the city of Lagarto, Sergipe, Brazil were gathered for analyzing iodate concentration. The amounts of salt added to meals of four schools in the city and the weight of the provided meals were recorded during two consecutive days of gathering, thus obtaining data to estimate the iodine content of these meals. The rest of the meals and the nutritional composition of school meals were analyzed. A questionnaire for participants on the perception of salt was applied. For data analysis, α = 5% was used.

The iodine concentration in all salt samples followed legislation (15 to 45 mg of iodine/kg of salt), with the average of iodine ranged between 26.5 ± 1.29 and 33.9 ± 2.49 mg/kg (p < 0.001). The estimated iodine content in consumed school meals was 0.025 mg (25 µg), in meals of schools A and C, it was 0.03 ± 0.02 mg, and to schools B and D, it was 0.02 ± 0.01 mg (p < 0.001). Percentages of rest of the meals greater than 10% were found and the assessed food preparation showed low caloric and nutritional values.

The iodine content is in accordance with the salt iodization policy in Brazil, and that the average iodine estimate in school meals was considered adequate for this population.

This paper aims to analyse the state of performance management in the Portuguese public sector as part of the efforts towards public administration reform.

Theoretically, the authors took Bouckaert and Halligan's (2008, pp. 35–39) approach into consideration to analyse the adoption of performance management practices. This approach was supplemented by an adaptation of Pollitt and Bouckaert's (2011, p. 33) framework to analyse the context for administrative reforms. The used data analysis techniques include documentary analysis (namely legislation and evaluation reports of reform efforts), secondary data analysis and a survey conducted with 296 Portuguese top public managers.

The findings show that Portuguese public sector organisations adopted several tools to measure performance over the years, but failed to incorporate performance information into their management practices or to properly use it for either internal or external purposes. Concerning the ideal types proposed by Bouckaert and Halligan (2008, p. 36), Portugal is considered to fit the “performance administration” ideal type, even though it is moving closer to the “managements of performance” ideal type.

This is one of the first comprehensive studies on the state of performance management in Portugal framed within the broader context of public sector reforms. The findings will be of interest both to scholars who study public administration reforms and performance management and to Portuguese policy makers and public managers who are interested in understanding and improving the way performance information is measured, incorporated and used in that sector.

Human beings spend about a third of their day working, so it is very important that they are integrated into a good community work environment. When the setting is teleworking in a family and housing context, it is important to keep a good environment and also a good physical, psychological and ergonomic aspects to attain job performance. The purpose of this paper is to characterize teleworking carried out in Portuguese communities in the context of the state of emergency caused by the COVID-19 pandemic.

A survey questionnaire was used, which analyzed general information about teleworking and the individual’s adaptation process and the difficulties they faced during the teleworking period. The sample consists of 359 individuals aged 18 years or over, who were teleworking in their homes and in a family environment.

The results show that adapting to teleworking was easy or very easy and that it happened very quickly. The main difficulties encountered by the individuals were the lack of professional interaction/communication with coworkers, the lack of resources related to support infrastructures, such as the internet or a printer, and the reconciliation of teleworking with family life/household chores/dedication to children and time/schedule management.

This study hopes to contribute to the increase of the scientific knowledge in the teleworking field and to allow companies to rethink the teleworking strategies to optimize resources and costs and to improve the organization’s productivity without harming the quality of life and well-being of their workers.

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.

Social movement research often focusses on phases of success and large protest events. By contrast, taking an interest in the question of how organizational change occurs within social movements, this study points out the importance of phases of low protest activity. The organizational structure of the Portuguese anti-austerity protests provides a thought-provoking case, as large protests organized by civil society actors other than the trade unions were a novelty in 2011. Furthermore, there are long periods of absence of large protests, and the organizational structure of the protests has undergone significant changes. Based on fieldwork in Portugal between September 2011 and March 2013, I differentiate between four phases in the organization of protests against austerity. I argue that it is mainly times of low degrees of activism – times that are rarely taken into account by social movement research – that lead to radical changes in the organizational structure of a social movement. The impact of the following factors on the direction of change is analyzed: (a) strategic choice; (b) values and normative commitments; (c) (potential) alliances and participants; (d) inspiration from other cases of social movement activism; and (e) learning processes, the history of social movements and the impact of memory.

The purpose of this study is to provide a revision of the literature that links the concepts of sustainability and internationalization in the context of emerging markets

The results are presented following the recommendations of Challahan (2014), who introduced the concept of the “Six W” as components of a literature review.

It can be noted that there are common characteristics among the study of internationalization and sustainability in emerging markets. It is possible to suggest a framework of research that considers internationalization as a driver for the pursuit of sustainability initiatives.

There is an increasing evidence of the inclusion of corporate social responsibility activities and sustainable development on international business. This way, the present paper can serve as a base to understand the internationalization processes of emerging market multinationals (EMNEs) and their commitment to sustainability.

The purpose of this paper is to analyse the neutrality of a management control approach and verify if it incorporates North‐American values.

The paper applies a discourse analysis methodology to make evident the North‐American values involved in legitimating the rationality embedded in the practices of a management control approach.

The approach imposes North‐American values as the best choice, pretending to be neutral and context‐independent.

The paper calls attention to the need to contextualise imported management knowledge supposed to be technical, neutral and universal.

The paper contributes to the process of revealing the reproduction of Anglo‐Saxon ideologies in organisational knowledge transferred to Latin America.
