Abstract
Purpose
This paper aims to analyze what Samarco and Brazilian magazines speak and say about Mariana’s environmental crime. Discover their doxa in this subject. Interpret the speakings, sayings and doxas through the theories of the treadmills of production, crime and law.
Design/methodology/approach
It is a qualitative and documental research and a narrative analysis. Regarding the documents: 45 were from public authorities, 14 from Samarco Mineração S.A. and 73 from Brazilian magazines. Theoretically, the authors resorted to Bourdieusian sociology (speaking, saying and doxa) and the treadmills of production, crime and law theories.
Findings
Samarco: speaking – mission statements; saying – detailed information and economic and financial concerns; doxa – assistance discourse. Brazilian magazines: speaking – external agents; saying – agreements; doxa – attribution, aggravations, historical facts, impacts and protests.
Research limitations/implications
The absence of discussions that addressed this fatality, with its respective consequences, from an agenda that exposed and denounced how it exacerbated race, class and gender inequalities.
Practical implications
Regarding Mariana’s environmental crime: Samarco Mineração S.A. speaks and says through the treadmill of production theory and supports its doxa through the treadmill of crime theory, and Brazilian magazines speak and say through the treadmill of law theory and support their doxa through the treadmill of crime theory.
Social implications
To provoke reflections on the relationship between the mining companies and the communities where they settle to develop their productive activities.
Originality/value
Concerning environmental crime in perspective, submit it to a theoretical interpretation based on sociological references, approach it in a debate linked to environmental criminology, and describe it through narratives exposed by the guilty company and by Brazilian magazines with high circulation.

Abstract
Purpose
The purpose of this review paper is to outline the parachute materials and its behavior. To enhance parachute life, it is highly desirable to consider the commercial angle for any parachute manufacturing industry and its components under varying operational conditions. Hence, the knowledge of various textile materials and operational conditions which contributes the parachute strength and durability will be helpful for industries/researchers.
Design/methodology/approach
This section is not applicable for a review paper.
Findings
Parachute is a material used in numerous real-time applications such as man-drop, cargo delivery, aircraft recovery and aircraft decelerator which drastically reduces human efforts and time. However, each application requires a unique design and fabric selection to achieve the area of drag needed and the terminal velocity of the parachute material while in flight. For designing a man-drop parachute, the most critical parameters are weight and strength which must be considered during manufacturing. The army person uses the man-drop parachute, which must be as light as possible.
Originality/value
This paper is an original review work and will be helpful for parachute manufacturers/researchers to enhance the life of parachutes with improved functionality.

Abstract
Purpose
The purpose of this study is to reflect on and analyse the sensory experiences related to the transition to remote work during the COVID-19 pandemic. The research seeks to understand how these experiences have influenced the integration of work practices into home and family life and the subsequent adaptations and embodied learning that arise in response.
Design/methodology/approach
The authors' research approach incorporates autoethnographic methods to explore the sensory, affective and emotional experiences of transitioning to remote work. The authors draw on principles of embodied learning, as influenced by Gilles Deleuze, and utilise a range of ethnographic tools including note-taking, audio memos, photography, shared conversations and written reflections to gather their data.
Findings
The study illuminates the ways bodies learn to accommodate the new organisational contexts that arise when the spaces, affects and forces of home and work intersect. It demonstrates how the integration of work into the private domain resulted in new affective and material arrangements, involving novel sensory experiences and substantial embodied learning.
Originality/value
This study provides a distinct, sensory-oriented perspective on the challenges and transformations of remote work practices amid the pandemic. By focussing on the affective resonances and embodied learning that emerge in this context, it contributes to the emerging discourse around post-lockdown work practices and remote work in general.

Abstract
Purpose
The objective of this research is to evaluate the influence of mineral additions on the mechanical performances of polymer concrete. This study aims to propose a novel approach formulation of polymer concrete based on reduction in the quantity of the binder and disposal of large quantities of industrial by-products and household waste such as the marble, the brick and silica fume whose valuation in polymer concrete could be an interesting ecological and economical alternative. The incorporation of a rate of 10% brick powder affects the distribution of pores inside polymer concrete, that is, the pore diameters become thinner and decrease and the porosity becomes evenly distributed. The recycled mineral brick powder addition in polymer concrete mix improved the mechanical properties.
Design/methodology/approach
This polymer concrete was prepared by using polyester resin and two different types of sand, following a new formulation based on an empirical method. Furthermore, the optimal binder percentage was of 20% resin and a mixture of 52% dune sand and 48% quarry sand according to the Abrams method. To achieve our objective, five rates (from 2% to 10%) of brick powder, marble powder and silica fume were examined. Afterwards, its mechanical characteristics were evaluated via a three-point flexural with compressive resistance. The findings indicated that the addition of brick, marble and silica fume to polymer concrete increases the flexural strength with 21.84%, 12.76% and 9.07%, respectively.
Findings
Concerning the compressive strength, the best resistance is that of polymer concretes based on brick powder, and this economic formulation of polymer concrete serves the optimal cost/resistance ratio criteria. It allows an improvement in the mechanical resistance of concrete are obtained by adding brick powder that exceed that of the reference concrete.
Originality/value
In the past few decades, there has been several contribution concerning the subject of the reduction of the binder quantity in polymer concretes and adding the industrial and household wastes. However, previous studies revolving around the same area disregarded the effect of the brick powder, which appears scientifically of great importance for enriching the literature.

Abstract
Purpose
Language plays a complex role in coaching, facilitating communication, comprehension and meaning construction. Yet, the implications of coaching in a non-native language are uncertain and under-researched. This study explores the role of non-native language (NNL) in dyadic workplace coaching practice. Specifically, it explores how working in a NNL influences the coaching experience from the coach’s perspective.
Design/methodology/approach
A qualitative approach was chosen to explore the way coaches view coaching in a NNL. Twenty-three semi-structured interviews were conducted with coaches experienced in coaching in NNL. Reflexive thematic analysis (RTA) was applied for data analysis.
Findings
NNL coaching presents a paradoxical mix of negative and positive tensions for the coach and coachee in communication, relationship and insight. NNL coaching is nuanced and may be accommodated using coaching competencies to mitigate the potential for misunderstanding and relationship rupture. It offers alternative perspectives to existing worldviews, eliciting deeper insights. Coaches’ confidence in coaching in a NNL varies from a challenging struggle that perceptually hinders performance, through ambivalence, to a sense of greater resourcefulness.
Originality/value
The study contributes to the stream of literature on language in international business, sociolinguistic research and how meaning is constructed in a coaching process. First, the work develops a distinction between coaching in a native language (NL) and a NNL. Second, study results indicate that the context of NNL creates challenges as well as opportunities in a dyadic coaching process, particularly regarding aspects of the coach–coachee relationship and insight elicitation via alternative perspectives. Moreover, several practical implications of the study for the coaching practice are discussed.

In this paper, the seismic behavior of the gusset plate moment connection (GPMC) exposed to the post-earthquake fire (PEF) is investigated.
Abstract
Purpose
In this paper, the seismic behavior of the gusset plate moment connection (GPMC) exposed to the post-earthquake fire (PEF) is investigated.
Design/methodology/approach
For this purpose, for the sake of verification, first, a numerical model is built using ABAQUS software and then exposed to earthquakes and high temperatures. Afterward, the effects of a series of parameters, such as gusset plate thickness, gap width, steel grade, vertical load value and presence of the stiffeners, are evaluated on the behavior of the connection in the PEF conditions.
Findings
Based on the results obtained from the parametric study, all parameters effectively played a role against the seismic loads, although, when exposed to fire, it was found that the vertical load value and presence of the stiffener revealed a great contribution and the other parameters could not significantly affect the connection performance. Finally, to develop the modeling and further study the performance of the connection, the 4 and 8-story frames are subjected to 11 accelerograms and 3 different fire scenarios. The findings demonstrate that high temperatures impose rotations on the structure, such that the story drifts were changed compared to the post-earthquake drift values.
Originality/value
The obtained results can be used by engineers to design the GPMC for the combined action of earthquake and fire.

Abstract
Purpose
The purpose of this paper is to examine the supervening loss of inter-organisational trust in long-term commercial contracts. The underlying research question is whether contract law – the legal institution regulating economic exchanges – should intervene and enable a party to a long-term commercial contract to extricate itself from a situation where a relationship of trust has broken down irretrievably.
Design/methodology/approach
This paper uses doctrinal methodology and theoretical conceptualisation to answer the underlying research question. The legal instrument chosen for analysis purposes is the UNIDROIT Principles of International Commercial Contracts. This paper also draws on extant literature on inter-organisational trust (including conceptual and empirical studies) to support the arguments and propositions. Furthermore, this study proceeds to assess the substantive justifiability of the proposed remedial measure using four normative values: legal certainty and predictability, protection of the performance interest, economic efficiency and the preservation of the relation.
Findings
The central argument put forward in this paper is the reformulation of draft Article 6.3.1 proposed by the UNIDROIT Working Group on Long-Term Contracts, which confers a novel right to terminate for a compelling reason. This paper presents a multidimensional model of inter-organisational trust that would serve as the conceptual framework for the proposed reformulation of the provision and establishes a coherent juridical basis for the legal solution that would accord with the Principles of International Commercial Contracts’ general remedial scheme. As for the normative assessment, this paper demonstrates that the proposed remedial measure would significantly promote efficient outcomes and positively serve the norms of legal certainty, protection of the performance interest and the preservation of the relation.
Originality/value
This paper addresses the lacuna in current legal scholarship in relation to the adverse socio-economic effects following trust violation and deterioration in inter-organisational relationships. Additionally, the propositions and findings should contribute to the workings of the UNIDROIT in adopting new rules and principles that would serve the special requirements of cross-border trade.

Abstract
Purpose
This paper aims to present numerical simulations for a series of flight processes for the postlaunching stage of the “balloon-borne UAV system.” It includes the balloon further ascent motion after airborne launching. In terms of unmanned aerial vehicles (UAVs), the tailspin state and the charge-out process with an anti-tailspin parachute-assisted suspending are analyzed. Then, the authors conduct trajectory optimization simulations for the long-distance gliding process.
Design/methodology/approach
The balloon kinematics model and the parachute Kane multibody dynamic model are established. Using steady-state tailspin to reduced-order analysis and achieving change-out simulation by parachute suspension dynamic model. A reentry optimization control problem is developed and the Radau pseudo-spectral method is used to calculate the glide trajectory.
Findings
The established dynamic model and trajectory optimization method can effectively simulate the motion process of balloons and UAVs. The system mass reduction for launching UAVs will not cause damage to the balloon structure. The anti-tailspin parachute can reduce the UAV attack angles effectively. The UAV can glide to the designated target position by adjusting the attack angle and sideslip angle. The farthest flight distance after launching from 20 km height is 94 km and the gliding time is 40 min, which demonstrates the potential application advantage of high-altitude launching.
Practical implications
The research content and related conclusions of this article achieve a closed-loop analysis of the flight mission chain for the “balloon-borne UAV system,” which provides simulation references for relevant balloon launching experiments.
Originality/value
This paper establishes a complete set of numerical simulation models and can effectively analyze various postlaunching behaviors.

Abstract
Purpose
This paper aims to investigate how narrative is constructed to create connections with fat readers, how books function to envision spaces of fat liberation for young readers and to highlight the incredible importance of providing bigger mirrors (Bishop, 1990) for fat representation in children’s literature.
Design/methodology/approach
This paper analyzes and reflects on two texts that contain counternarratives of fatness: The (Other) F Word: A celebration of the fat and fierce edited by Angie Manfredi (2019) and Big by Vashti Harrison (2023) to interrogate how these two narratives intentionally disrupt anti-fat bias.
Findings
Body size and fatness are identities that need to be included in diversity efforts within education. Books like The (Other) F Word: A celebration of the fat and fierce (Manfredi, 2019) and Big (Harrison, 2023) offer positive representations of fatness, disrupt biases around body size and provide spaces that allow fat students to find joy, hope, connection and, more than anything, imagine a way toward liberation.
Research limitations/implications
This paper highlights the need to include more narratives of positive fat representation within children’s literature and calls for educators to interrogate their own anti-fat biases and practices.
Originality/value
There is a lack of research on fat representation specifically within children and young adult literature. This paper provides an analysis of two pieces of literature with fat representation that brings attention to the need for this type of future research.
