Here are summaries of more papers given at the International Conference on Hot Dip Galvanising which met at Oxford in July under the auspices of the Zinc Development Association and which was attended by about 200 experts from Britain, the Continent, and America. The first report on the Conference appeared in our August issue.

Among the many influencing effects that the medium has on the CO₂ corrosion of carbon steel, flow is one of the most important because it can determine the formation of corrosion product scales and its stabilisation, thus influencing the attack morphology and corrosion rate. This paper aims to summarise some factors affecting aqueous CO₂ corrosion and the laboratory methodologies to evaluate one of the most important, the flow, with an emphasis on less costly rotating cage (RC) laboratory methodology.

Regarding the key factors affecting CO₂ corrosion, both well-established factors and some not well addressed in current corrosion prediction models are presented. The wall shear stress (WSS) values that can be obtained by laboratory flow simulation methodologies in pipelines and its effects over iron carbonate (FeCO₃) scales or inhibition films are discussed. In addition, promising applications of electrochemical techniques coupled to RC methodology under mild or harsh conditions are presented.

More studies could be addressed that also consider both the salting-out effects and the presence of oxygen in CO₂ corrosion. The RC methodology may be appropriate to simulate a WSS close to that obtained by laboratory flow loops, especially when using only water as the corrosive medium.

The WSS generated by the RC methodology might not be able to cause destruction of protective FeCO₃ scales or inhibition films. However, this may be an issue even when using methodologies that allow high-magnitude hydrodynamic stresses.

This study examines how applying innovative I4.0 technologies at the design stage can help reduce construction waste and improve the recovery, reuse, and recycling of construction materials.

The study adopts a three-stage sequential mixed methods approach, involving a thorough review of current literature, interviews with six experts in digital construction, and a survey of 75 experienced industry practitioners.

The study identifies and discusses how ten specific digital technologies can improve design stage processes leading to improved circularity in construction, namely, (1) additive and robotic manufacturing; (2) artificial intelligence; (3) big data analytics; (4) blockchain technology; (5) building information modelling; (6) digital platforms; (7) digital twins; (8) geographic information systems; (9) material passports and databases; and (10) Internet of things. It demonstrates that by using these technologies to support circular design concepts within the sector, material recycling rates can be improved and unnecessary construction waste reduced.

This research provides researchers and practitioners with improved understanding of the potential of digital technology to recycle construction waste at the design stage, and may be used to create an implementation roadmap to assist designers in finding tools and identifying them.

Little consideration has been given to how digital technology can support design stage measures to reduce construction waste. This study fills a gap in knowledge of a fast-moving topic.

Examines the issue of how variations in language used in advertising affect advertising preference with a sample of bilingual, Korean Americans. Uses past literature to hypothesise that the level of acculturation would moderate ethnic consumers’ preference for advertisements in English versus their native language. Extends previous research in the field of ethnic advertising by considering whether findings from studies conducted with Hispanic American consumers are applicable to Asian Americans. Shows that no significant differences were detected in bilingual Korean American preferences for advertisements in which the message was presented in English as compared with those that used Humgul (Korean language) to communicate with the audience. Concludes with suggestions for further research.

The chapter aims to compare public, private and non-profit working citizens’ preferences for cross-sectoral relations in England and Finland. Its main contribution is in identifying preferences in the delivery of services in the respective countries in which citizen choice has become an issue in times of public sector austerity. Challenges arise because in these two similarly institutionalized healthcare systems but pluralistic societies people have contrasting perspectives on the values that should guide policy decisions. The survey data was therefore collected in both England (N = 2,000) and Finland (N = 1,973) in 2013 from cities in which citizens have choices regarding health service delivery. Our informants in England anticipated more potential for better ‘privatized driven public interest’ than did those in Finland. Surprisingly, over 60% of public sector employees in England would like for-profit healthcare to carry main responsibility, and almost 55% of all employees agree with this. Almost 20% of respondents in both countries did not care who the service provider is if only services are available. Thus, the research has pioneering relevance for policymaking, public strategic management and the comparative empirical study of managing people’s preferences in cross-sectoral relations. We conclude that identifying working citizens’ preferences is crucial for effective utilization of current welfare services because the preferences derive from both service and work experience. In sum, strategically, this identification lets public managers balance biased images of the cross-sectoral differences and reconstruct functional hybridity of services.

Recent work on advertising acculturation suggests that ad agencies have changed their messages in order to appeal to immigrants. The following inquiry turns the tables and looks at how the role of foreign actors has been adapted in a country with a relatively homogeneous population. Specifically, how adaptive is the Japanese advertising industry? Has the behaviour of foreign actors been adapted to reflect Japanese culture? Using Duncan’s categories of the non verbal communication, the mannerisms of foreign actors are examined. The results suggest that acculturation is occurring at some level; however, the inclusion of stereo typical materials suggests some retention of foreign identity.

In urban planning, peri-urban areas are often addressed with an urban-centric view on development, disregarding the multifunctional and dynamic opportunities that these spaces offer. As a consequence, we argue that land use functions such as agriculture do not reach their full potential, despite the increasing enthusiasm for peri-urban and urban agriculture. This chapter has a twofold structure: first it explores the opportunities and challenges for agriculture in peri-urban areas; and second, it studies success factors for envisioning processes promoting peri-urban agriculture in urban policy and planning.

Through action research, we gather and compare data from two envisioning processes in the Flemish cities of Ghent and Kortrijk. Both processes were initiated by the local authorities, with the purpose of developing a spatial vision for agriculture in peri-urban areas.

Results show that in both contexts, pressure on farmland is a key issue. In addition, we highlight that multifunctionality is rather complex, both in practice and from a governance perspective, but nevertheless promising as a territorial concept in envisioning processes. Regarding the envisioning process itself, the analysis shows that clarity and consensus on the objectives of the process, delineation of the study area, policy support, clear leadership, and inserting sound and reliable data into the process are important success factors.

This chapter provides insight into the visions, plans and strategies needed to embrace the potential of agriculture in peri-urban areas, through the exploration and valuation of participatory envisioning processes. Future research is needed to explore the implementation phases of envisioning processes in urban planning.

Air pollution poses a significant global threat to both human health and environmental stability, acknowledged by the World Health Organization as a leading cause of non-communicable diseases (NCDs) and a notable contributor to climate change. This chapter offers a comprehensive review of the impacts of air pollution on health, highlighting the complex interactions with genetic predispositions and epigenetic mechanisms. The consequences of air pollution to health are extensive, spanning respiratory diseases, cardiovascular disorders, adverse pregnancy outcomes, neurodevelopmental disorders, and heightened mortality rates. Genetic factors play a pivotal role in shaping individual responses to air pollution, influencing susceptibility to respiratory illnesses and the severity of symptoms. Additionally, epigenetic changes triggered by exposure to pollutants have been linked to respiratory health issues, cancer development and progression, and even transgenerational effects spanning multiple generations. As countries, including the UK, pursue ambitious targets for reducing emissions, ongoing research into the complex interplay of air pollution, genetics, and epigenetics is essential. By unravelling the underlying mechanisms and advancing preventive and therapeutic strategies, we can protect public health and promote sustainable environmental practices in the face of this pervasive global challenge.

Purpose – The chapter answers the question if urban regime theory (URT) can provide a useful framework to understand and solve problems of cooperation in regional processes in rural–urban areas.

Methodology/approach – The chapter is a theoretical discussion on problems found in contemporary rural spatial governance.

Findings – URT can provide a framework for understanding the obstacles encountered in regional development and is a promising perspective for the analysis of regional processes. A solution for problems in regional cooperation can be found in so-called ‘vital coalitions’, forms of vital interaction between regional actors, based on energy and productivity, that can create a ‘capacity to act’ in regions that have become ‘gridlocked’ by current procedures and regulations.

Research limitations/implications – A modern URT, applied in a regional context:(1)Can point out ‘how power is organised to act’;(2)Analyses informal networks between actors as bases for cooperation and vitality, and as a possible starting point for new (cultural) counter-regimes and(3)Offers insight into regional complexity and cooperation and into emergent regimes.

Practical implications – Vital coalitions are forms of self-governance, that introduce new agendas and function as forms of niche-innovation in regions. This can lead to the forming of new ‘cultural regimes’ in which the motives and values of civilians are a key element.

Originality/value of the chapter – The value of the chapter lies in the use of concepts in regions from a fresh new perspective, by translating the URT from a local, urban context to a regional rural–urban perspective.
