Abstract
Purpose
The design of a space launcher requires some considerations about the unsteady loads and heat transfer occurring at the base of the structure. In particular, these phenomena are predominant during the early stage of the flight. This paper aims to evaluate the ability of the unstructured, high order finite-volume CFD solver FLUSEPA, developed by Airbus Safran Launchers, to accurately describe these phenomena.
Design/methodology/approach
This paper first performs a steady simulation on a base flow around a four-clustered rocket configuration. Results are compared with NASA experiments and Loci-CHEM simulations. Then, unsteady simulations of supersonic H2/air reacting mixing layer based on the experiment of Miller, Bowman and Mungal are performed. Three meshes with different cells number are used to study the impact of spatial resolution. Instantaneous and time-averaged concentrations are compared with the combined OH/acetone planar laser-induced fluorescence imaging from the experiment.
Findings
FLUSEPA satisfactorily predicts the base heat flux at the base of a four-clustered rocket configuration. NASA Loci-CHEM reactive simulations indicate that afterburning plays an important role and should not be neglected. The unsteady reactive computation of a supersonic mixing layer shows that FLUSEPA is also able to accurately predict flow structures and interactions. However, the complexity of the experiment and the lack of details concerning the facility prevents from obtaining satisfactory converged results.
Originality/value
This study is the first step on the development of a cost-effective method aiming at predicting unsteady loads and heat transfer on space launchers using an unsteady and reactive model for the CDF calculations. It uses original techniques such as conservative CHIMERA-like overset grids, local re-centering of fluxes and local adaptive time-stepping to reduce computational cost while being robust and accurate.

Abstract
Given that the workforce constitutes a principal resource of primary care, appraisal of models of care requires thorough investigation of the health workforce in all Models of Child Health Appraised (MOCHA) countries. This chapter explores this in terms of workforce composition, remuneration, qualifications and training in relation to the needs of children and young people. We have focused on two principal disciplines of primary care; medicine and nursing, with a specific focus on training and skills to care for children in primary care, particularly those with complex care needs, adolescents and vulnerable groups. We found significant disparities in workforce provision and remuneration, in training curricula and in resultant skills of physicians and nurses in European Union and European Economic Area Countries. A lack of overarching standards and recognition of some of the specific needs of children reflected in training of physicians and nurses may lead to suboptimal care for children. There are, of course, many other professions that also contribute to primary care services for children, some of which are discussed in Chapter 15, but we have not had resources to study these to the same detail.

Abstract
Two concurrent changes are raising questions about the interplay between armed forces and local governments in contemporary urban settings. The first one is the spatial reorganisation of armed forces that has been taking place in most European countries since the end of the Cold War. The second one is the redistribution of political authority between levels of governments that has increased the relevance of cities and transformed urban governance. The chapter conceptualises the military administration as an urban actor, whose material and symbolic resources in cities transform over time. It investigates both the effects of a (changing) military presence on urban policies, and how those changes are framed and managed by local governments. The case under consideration is the city of Taranto (Southern Italy), one among the biggest military ports on the Mediterranean Sea. Here, transformations of defence policies opened a window of opportunity for a new urban policy agenda, whose goal is a partial differentiation from military activities. During the last ten years, local political elites have been undertaking several strategies for military spaces redevelopment. However, uneven power relations prevent civilian-military bargain: redevelopment strategies are the result of either local military initiative or central State decisions.

Abstract
This chapter examines the relationship between finance capital and the transformation of the state in Rudolf Hilferding’s thought. Hilferding defines finance capital as the fusion of banking and industry, a situation that presupposes a high degree of development of capitalist relations. Finance capital prompts a transformation of the state economic functions. This chapter considers the transformation of the state and its consequent ability to deal with crises of finance capital era. It also highlights Hilferding’s pioneering contribution in sketching the bases for the great contemporary theories of State intervention in crises regulation.

Abstract
Models of Child Health Appraised (MOCHA) defines school health services (SHSs) as those that exist due to a formal arrangement between educational institutions and primary health care. SHSs are unique in that they are designed exclusively to address the needs of children and adolescents in this age group and setting.
We investigated SHSs have been provided to schools and how they contribute to primary healthcare services for school children. We did this by mapping the national school health systems against the standards of the World Health Organization, and against a framework measuring the strength of primary care, adapting this from an existing, adult-focused framework.
We found that all but two countries in the European Union and European Economic Area have SHSs. There, however, remains a need for much greater investment in the professional workforce to run the services, including training to ensure appropriateness and acceptability to young people. Greater collaboration between SHSs and primary care services would lead to better coordination and the potential for better health (and educational) outcomes. Involving young people and families in the design of SHSs and as participants in its outputs would also improve school health.

Abstract
La physionomie hôtelière d'une station de tourisme est un des premiers aspects que retient le visiteur. Qui ne s'est pas senti écrasé, en sortant de la petite gare de St‐Moritz, par la superposition au flanc de la montagne de ces hôtels construits comme des châteaux‐forts ? Ce sont effectivement des citadelles, datant d'une époque qui a eu ses Vauban hôteliers. Dans les Rocheuses canadiennes (Banff, Lake Louise), l'habitat touristique qui est un habitat isolé, est concentré dans des palaces énormes aux yeux des Européens, cantonnés de tours, avec des toits en poivrières. Ils s'imposent comme des «Pierre‐fonds » du logement dans le décor de la montagne. Tout au contraire d'autres stations manifestent une pudeur hôtelière du meilleur goût. On dirait qu'elles ne veulent pas se faire remarquer. Dans le Tyrol on cherche en vain un hôtel de style tapageur: tout l'habitat touristique est disséminé dans les stations sous forme de chalets de dimensions modestes offrant souvent 30 chambres et se confondant avec l'habitat rural originel. C'est une autre expression de la physionomie hôtelière. Elle sous‐tend une importante réalité économique: tandis que les palaces‐châteaux représentent un capitalisme hôtelier dont on se demande en maintes régions s'il a fait époque, les petits htels‐chalets sont gérés souvent sous forme artisanale. La concentration nous conduit à penser à deux modes distincts d'exploitation hôtelière. Ces deux modes ne sont pas absolument indépendants de la vie de la station touristique. Pourrait‐on dès lors prendre la concentration hôtelière comme fil conducteur de la structure économique d'une station de tourisme?

Abstract
Purpose
This study aims to explore the perspectives of psychiatrists with lived experiences and what their considerations are upon integrating the personal into the professional realm.
Design/methodology/approach
As part of a qualitative participatory research approach, participant observations during two years in peer supervision sessions (15 sessions with 8 psychiatrists with lived experiences), additional interviews as part of member feedback and a focus group were thematically analysed.
Findings
Although the decision to become a psychiatrist was often related to personal experiences with mental distress and some feel the need to integrate the personal into the professional, the actual use of lived experiences appears still in its early stages of development. Findings reveal three main considerations related to the personal (3.1), professionality (3.2) and clinical relevance (3.3) comprising 11 facilitators and 9 barriers to harness lived experiences.
Research limitations/implications
This study was conducted locally and there are no similar comparable studies known. It was small in its size due to its qualitative nature and with a homogeneous group and therefore may lack generalisability.
Practical implications
Future directions to further overcome shame and stigma and discover the potential of lived experiences are directed to practice, education and research.
Originality/value
Psychiatrists with lived experiences valued the integration of experiential knowledge into the professional realm, even though being still under development. The peer supervision setting in this study was experienced as a safe space to share personal experiences with vulnerability and suffering rather than a technical disclosure. It re-sensitised participants to their personal narratives, unleashing its demystifying, destigmatising and humanising potential.

Abstract
Comics and graphic novels can disrupt traditional texts by challenging the “worship of the written word” (Torres, 2019), a feature of white supremacy that perpetuates textual hierarchies within educational spaces. Giving all of our students access to contemporary literature that centers Black youth perspectives is not only important in decolonizing literature education but also in presenting a holistic view of Black childhood. They can be used in the classroom as subjects to challenge stereotypical depictions by centering experiences, ideas, and concepts that are often marginalized in traditional curriculum. Within this chapter, we focus on comics and graphic novels as tools to enact students’ multiliteracies and to analyze visual stories depicting BlackBoy adolescence, using the frameworks of BlackBoy Crit Pedagogy (Bryan, 2022), an equity framework that interrogates the interdisciplinary ways that Black boy students' literacy learning can be formed through the teaching and learning of Blackness, maleness, and the schooling experiences of Black boys. We utilize this framework to analyze the use of diverse comics and graphic novels to facilitate critical conversations of bringing inclusive visual texts into the classroom. We invite practitioners to reimagine curricular ideas and content centered on empowerment and Black boy adolescence and how those ideas are presented to youth through a variety of visual narratives.

Abstract
Purpose
New product concept screening, i.e., selecting a few viable innovative concepts from numerous candidates, involves high stakes and is complicated and resource intensive. Over the years, there has been heated debate about the relative merit of monadic (sequential) tests vs that of preference-based paired comparisons. The paper aims to discuss these issues.
Design/methodology/approach
This study proposes the Generalizability Theory as a framework to assess and compare the performance of traditional monadic test with the Adaptive Concept Screening (ACS) in terms of their testing results and psychometric quality.
Findings
Using 50 yogurt concepts and two independent groups of respondents, the results indicate that ACS requires a significant smaller sample of respondents to achieve a necessary minimum G coefficient for decision making. Moreover, ACS offers a more discriminating and reliable solution for early stage concept screening as manifested by a higher G coefficient and greater percentage of variance due to the selected concepts given the same sampling design.
Practical implications
The results lend strong support to ACS as a more cost-effective method for screening new product concepts and the Generalizability Theory as a systematic framework for assessing concept testing methods.
Originality/value
This study adopts the Generalizability Theory framework to assess the validity of new product concept screening method.
