Intumescent coatings are nowadays a dominant passive system used to protect structural materials in case of fire. Due to their reactive swelling behaviour, intumescent coatings are particularly complex materials to be modelled and predicted, which can be extremely useful especially for performance-based fire safety designs. In addition, many parameters influence their performance, and this challenges the definition and quantification of their material properties. Several approaches and models of various complexities are proposed in the literature, and they are reviewed and analysed in a critical literature review.

Analytical, finite-difference and finite-element methods for modelling intumescent coatings are compared, followed by the definition and quantification of the main physical, thermal, and optical properties of intumescent coatings: swelled thickness, thermal conductivity and resistance, density, specific heat capacity, and emissivity/absorptivity.

The study highlights the scarce consideration of key influencing factors on the material properties, and the tendency to simplify the problem into effective thermo-physical properties, such as effective thermal conductivity. As a conclusion, the literature review underlines the lack of homogenisation of modelling approaches and material properties, as well as the need for a universal modelling method that can generally simulate the performance of intumescent coatings, combine the large amount of published experimental data, and reliably produce fire-safe performance-based designs.

Due to their limited applicability, high complexity and little comparability, the presented literature review does not focus on analysing and comparing different multi-component models, constituted of many model-specific input parameters. On the contrary, the presented literature review compares various approaches, models and thermo-physical properties which primarily focusses on solving the heat transfer problem through swelling intumescent systems.

The presented literature review analyses and discusses the various modelling approaches to describe and predict the behaviour of swelling intumescent coatings as fire protection for structural materials. Due to the vast variety of available commercial products and potential testing conditions, these data are rarely compared and combined to achieve an overall understanding on the response of intumescent coatings as fire protection measure. The study highlights the lack of information and homogenisation of various modelling approaches, and it underlines the research needs about several aspects related to the intumescent coating behaviour modelling, also providing some useful suggestions for future studies.

Suspicions about space technologies can be regarded as instances of “space skepticism,” i.e. the broadly pessimistic view that human activities in space are untimely or liable to be counterproductive. Section 1 will explain that contemporary space skepticism is focused upon negative societal role rather than the physical possibility of the activities proposed. Such skepticism is a complex pool of familiar claims unevenly drawn upon rather than a single theory. Section 2 will suggest that contemporary space skepticism tends to integrate with a broader set of doubts and fears about technologies of the Anthropocene. Section 3 will draw out a tension within the skeptical complex between the idea that concern for space is irrelevant to our societal problems and the idea that it is likely to make such problems worse. Section 4 will briefly outline why the publicly dominant forms of space skepticism carry a growing capability for merger with political activism and why the publicly dominant skepticisms are not necessarily those with the greatest plausibility, but rather those with the strongest motivational force. Finally, Section 5 will set aside the issue of popular motivational force and focus instead upon the skepticisms with the greatest plausibility. It will briefly outline why the relevant fears and suspicions (about military tensions and geoengineering) are outweighed by other considerations. This response to plausible skepticisms will not aim to be comprehensive but indicative of the direction of travel for more detailed critique. It will provide a framing context for a large metaphor about space technologies allowing the Earth to breathe.

This case study draws on secondary sources as well as my personal experience and industry contacts within the cement sector during my time teaching in Spain, a country where the cement industry plays a significant role in the economy. I have also benefited from conversations with my colleague, Arnaud Blandin, an ESG expert with a deep understanding of the sustainability challenges facing the cement industry, particularly in Asia, where he lived for several years. His contribution is acknowledged in the disclaimer below the title.

This case study explores how Holcim, the global leader of the cement industry addresses the sustainability imperatives through a set of structured initiatives and policies. The case focuses on the challenges faced by Holcim at a time when the imperatives of climate change, resource scarcity and stakeholder expectations converged to reshape the very foundations of its business strategy, compelling the firm to reimagine its operations through a lens of environmental, social and governance principles. The case starts with a brief description of the industry of cement, which is, at the same time, one of the most consumed products globally but also a major contributor to global carbon dioxide emissions and then to global warming. Next, the case briefly introduces Holcim and its major competitors. Then, the case presents the major environmental challenges for the cement industry as well as the possible solutions with operational advances, innovation and collaboration within actors. Finally, the case details the ESG strategy of Holcim in 2023 with a first evaluation of its results.

This case study has been written for Master of Business Administration and Master of Science students. The case can be used in multiple courses, including Corporate Strategy, Business and Society, Ethics and Sustainability, Corporate Social Responsibility and General Management Implementation.

Culture (traditional or organisational) has tended to be either a resource or an impediment to socio-economic development (SED) because culture plays an important role in the socio-economic sphere. This study investigates traditional culture that influences SED in light of the prevailing socio-economic situation in the Kingdom of Eswatini (Previously known as the Kingdom of Swaziland). Based on the existing demographics and political state, most people of the Kingdom live in rural areas, where traditional culture is predominant, and poverty is prevalent. That justifies their advocacy for SED influenced by cultural and traditional structures as opposed to one influenced by the internationally inclined modern democratic structures. This study used quantitative approaches and collected data from 30 ‘SED initiatives’. Results of the study indicate that traditional cultural influence is most prevalent in rural communities, while the adoption of the new national constitution in 2005 brought an insignificant change in the way culture influences SED. It was also noted that cultural governance, cultural tourism, customs and traditions, gender discrimination and marginalisation of people living with disabilities are the main existing components relating to the area of the central phenomenon. Further findings indicate that Eswatini culture is largely epitomised by the existence of the Monarchy authority, as a wide range of beliefs, customs and traditions are entrenched in the core values of the same. This infers that the Kingdom of Eswatini is predominated by socio-cultural values, which necessitates a telling influence on SED issues.

This study aims to assess the spread of environmental literacy graduation requirements at public universities in the USA, and to highlight factors that mediate the adoption of this curriculum innovation.

The author analyzed the undergraduate general education curriculum requirements at all 549 public BA-granting higher education institutions in the USA between 2020 and 2022.

The study found that only 27 US public universities out of 540 have an environmental literacy graduation requirement, which represents 5% of universities and is substantially lower than previous estimates.

First, this study provides a more complete, more reliable and more current assessment of the graduation requirement’s presence at US tertiary institutions, and shows the number of universities that have implemented this innovation is lower than was estimated a decade ago. Second, it draws from the scholarship on the infusion of sustainability into the university curriculum to provide a comprehensive discussion of factors that mediate the pursuit and implementation of the graduation requirement. As well, it identifies factors that played a key role in one pertinent case.

The main objective of this study is to analyze consumers’ willingness to pay (WTP) for country-of-origin (COO) labels of two processed food products, disentangling the value of information (VOI) that consumers place on COO information from the value they place on specific countries of origin.

A convenience sample of 96 university students completed a face-to-face experiment that included a multiple price list and a discrete choice experiment. Data are analyzed employing interval censored regressions, and random parameter logit models.

Our results indicate that, on average, consumers place a higher value on origin information when a country name is explicitly mentioned. Furthermore, COO information is, on average, more relevant to consumers for products with low involvement than for products with high involvement. Finally, the effect of ethnocentrism is heterogeneous across product categories.

Mandatory COO labeling may or may not reinforce domestic bias, depending on the rationale behind consumer support. If consumers are driven by blind ethnocentrism, it may lead to market inefficiencies. However, if they use COO as a cue to align their stated preferences with their choices, it will not. For this alignment to occur, consumers must be fully informed about product attributes, which requires new and smart methods of communicating product attributes.

The present study contributes to the literature on COO food labels, being the first in Italy to disentangle the VOI consumers place on origin information itself from the value they place on specific countries of origin. In addition, it is the first study that applies this methodology across different product categories, each of which has a different level of cultural sensitivity to consumers.
