Abstract
Purpose
This paper aims to extend current understanding concerning the cross-modal correspondences between sounds and tastes by introducing new research tools and experimental data to study associations and their reflections between music and taste.
Design/methodology/approach
The experiment design addresses the multidisciplinary approach by using cultural, chemical and statistical analysis methods.
Findings
The paper provides further evidence that exposure to the “sweet” or “sour” musical pieces influences people’s food-related thinking processes and behaviors. It also demonstrates that sweet or sour elements in the music may reflect to actual sweetness (as measured by sugar content) and sourness (as measured by organic acid content) of foods developed in association with music carrying similar taste characteristics.
Research limitations/implications
The findings should be replicated and expanded using larger consumer samples and wider repertoires of “taste music” and dependent variables. Also, the level of experimental control should be improved; e.g., the “sweet” and “sour” music were produced using different instruments, which may have an influence to the results.
Practical implications
Ambient “taste music” that is congruent with the basic flavors of the dishes can be played in restaurants to highlight guests’ sensory experience.
Social implications
By carefully considering the symbolic meanings of the music used in different social situations, it is possible to create multimodal experiences and even subconscious expectations in people’ minds.
Originality/value
Cross-modal associations are made between the tastes and music. This can influence on perception of food and provide new ways to build multimodal gastronomic experiences.

Abstract
Purpose
Food waste is generated along the entire agricultural supply chain. From farm overproduction to lack of cold chain infrastructure, waste occurs for multiple reasons and negatively impacts the environment and society while generating economic losses. Although various supply chain actors and institutions have made attempts to reduce it, the activity is often confined to a single farm or to a retailer and charity dyad, without a systematic resolution of the problem. The environment is not only negatively impacted by the reduction of soil, water and biodiversity but also human beings suffer from malnutrition and food insecurity and finally, the entire supply chain faces considerable economic losses. Various supply chain actors have attempted to reduce this waste, but the results are often limited. The purpose of this paper is to consider systematic resolution by proposing a reconceptualisation from an alternative Operations and Supply Chain Management (O&SCM) perspective.
Design/methodology/approach
The proposed paper is problem-based research, which merges the research and industry perspectives derived from the authors’ field experience interviewing different supply chain stakeholders in Italy, the UK, the USA and France with an analysis of O&SCM literature related to food loss and waste.
Findings
In order to address the food waste problem, we propose a new perspective in dealing with food loss and waste through the lens of O&SCM. By reconceptualising O&SCM theories and methods with the unique aspects of food loss and waste and taking into account the multitude of stakeholders involved, we propose five research avenues.
Originality/value
The perspective of O&SCM management is missing when dealing systematically with food loss and waste, as researchers neglect its unique characteristics.

Abstract
Purpose
Binder jetting is a promising route to produce complex copper components for electronic/thermal applications. This paper aims to lay a framework for determining the effects of sintering parameters on the final microstructure of copper parts fabricated through binder jetting.
Design/methodology/approach
The knowledge gained from well-established powder metallurgy processes was leveraged to study the densification behaviour of a fine high-purity copper powder (D50 of 3.4 µm) processed via binder jetting, by performing dilatometry and microstructural characterization. The effects of sintering parameters on densification of samples obtained with a commercial water-based binder were also explored.
Findings
Sintering started at lower temperature in cold-pressed (∼680 °C) than in binder jetted parts (∼900 °C), because the strain energy introduced by powder compression reduces the sintering activation energy. Vacuum sintering promoted pore closure, resulting in greater and more uniform densification than sintering in argon, as argon pressure stabilizes the residual porosity. About 6.9% residual porosity was obtained with air sintering in the presence of graphite, promoting solid-state diffusion by copper oxide reduction.
Originality/value
This paper reports the first systematic characterization of the thermal events occurring during solid-state sintering of high-purity copper under different atmospheres. The results can be used to optimize the sintering parameters for the manufacturing of complex copper components through binder jetting.

Abstract
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.

Abstract
The equivalent currents method has proven to be particularly effective in the identification of plasma boundary in Tokamak fusion devices. Anyway, the ill‐posedness of the mathematical model to be inverted calls for the adoption of suitable regularization techniques to be adopted, in particular to reduce the influence of the measurement errors. In this paper the equivalent currents method is illustrated, together with some details on its application to the plasma identification. In addition, two algorithms for the optimal choice of the representation basis are presented, together with a discussion about the obtained numerical results.

Abstract
Purpose
This paper aims to provide a case study focused on the substitution through selective laser melting of a part typically fabricated by traditional manufacturing.
Design/methodology/approach
To exploit the additive manufacturing (AM) advantages, the retrieving of the reconfiguration part data was provided, the process strategies by means of the interchange file handling and pre and post-processing were investigated and a re-design of the part was developed. Finally, the fabricated part was tested and analyzed.
Findings
Results claimed that a reconfiguration of the manufacturing framework plays an important role at each step of the process otherwise many AM benefits can be lost. In the paper, a set of recommendations, suggestions and hints regarding the implementation of AM for part substitutions is provided.
Research limitations/implications
Many aspects of the AM adoption, such as the production cost, energy consumption, sustainability and production volume, depend upon the geometry, batch size and other impactful factors, and thus they need to be studied in a case-by-case manner.
Practical implications
The proposed approaches have the concrete aim to address industrial resources toward the maximization of AM benefits in part substituting.
Originality/value
In this paper, the substitution of a part is fully undertaken from the early data collection to the manufactured part testing providing integrated approaches for each process step.

Abstract
The identification of plasma parameters from different sets of measurements is a key topic in the thermonuclear fusion research. Most of the information relevant to the plasma shape and position control is usually gained via external magnetic measurements, but information related to internal distribution of current density is not accessible in this way. Other possible measurements are available. In this paper a performance analysis is done with respect to the adoption of polarimetric measurements.

Abstract
Purpose
Energy consumption and renewable energy sources are included in the goals for the 2030 Sustainable Development Goal 7 (SDG7) agenda, and target buildings are the biggest electricity consumers. In turn, Netzero energy buildings (NZEB) contribute to achieve SDG7 goals. This paper aims to identify which Brazilian higher education institutions (HEIs) practices contribute to developing the NZEB concept.
Design/methodology/approach
Case studies were selected to identify which implanted practices applied by HEIs in Brazil, listed in the UI GreenMetric 2020 Ranking, are related to the NZEB concept. The implemented sustainable practices were also analyzed to evaluate the connections and impact between universities and the local community.
Findings
Results show the lighting and air conditioning retrofit were among the most common practices related to energy efficiency to reduce consumption. For renewable energy generation, photovoltaic solar energy is the most common practice used by HEIs.
Research limitations/implications
Only Brazilian HEIs listed in the UI Green Metric Ranking were analyzed. No standard regulation or formal reports support the wide dissemination of the strategies adopted by HEIs in Brazil.
Practical implications
The strategies adopted by HEIs related to Netzero buildings can reduce emissions, optimize operating costs and improve building comfort conditions, which connect all SDGs.
Social implications
HEIs can promote awareness related to energy use and clean energy generation within the local community.
Originality/value
This paper presents the most common strategies adopted by Brazilian HEIs. However, limitations related to lack of strategies, data transparency and specific Netzero energy regulation were also found. These issues can hinder other HEIs to adopt similar strategies and contribute to the promotion of SDG7 in Brazil.
