Abstract
In this chapter, the authors utilize both risk and resilience as conceptual frameworks to discuss the academic and psychosocial development of African American adolescent males. Given the amount of attention placed on the academic underachievement of African American males, they explore popular academic themes, such as academic disidentification and the role of teachers and parents. The authors examine psychosocial themes related to racial and athletic identity, the phenomenon of cool pose and “acting Black,” and the development of alternative masculinities. They conclude the chapter with recommendations for education research, practice and policy.

Abstract
Purpose
The purpose of this paper is to investigate the selenium content in seven different infant starting formulae, eight different follow‐on formulae and in 15 different special infant formulae, from various producers, all commercially available in Slovenia.
Design/methodology/approach
Each product was taken in various lots during a three‐year period (from 2004 to 2006). For the determination of selenium content in different infant formulae the method of hydride generation atomic fluorescence spectrometry (HG‐AFS) was optimised. The reliability of the method was checked by the independent method of radiochemical neutron activation analysis (RNAA).
Findings
The values for different infant formulae ranged from 20.9 to 207.9 ng/g powder. The paper compared the values obtained with the declared values where possible. The average concentration showed insufficient agreement with the declared value in four out of 30 cases. The paper also found significant variation in selenium content between formulae in the same group. In some cases, large variations between different lots of the same product were found.
Originality/value
Calculated from our results, from infant formulae babies obtain from 2.4 to 24.0 ug Se per day, showing insufficient agreement with recommended daily intakes published by D_A_CH and by WHO. Since information on the endogenous Se levels of infant formulae is largely lacking, therefore there is still need for stricter quality control of the selenium content in infant formulae.

Abstract
Previous work has suggested that the adhesion between oil and metallic surfaces of an engine could be an important factor in determining crankcase cleanliness. It can be shown that it is only necessary to measure the spreading pressure of an oil on metal in order to get a direct measure of the work of adhesion, Surface tensions of lubrictaing oils vary very little and it can be assumed that the critical film pressure (C.F.P.) obtained with a given apparatus is an acceptable measure of the work of adhesion as well as of the spreading pressure. Oils of similar properties may vary tenfold in their C.F.P's. The addition of additives influences the spreading pressure, the largest increments in C.F.P. being given by dispersant and detergent additives.

Abstract
The COVID-19 pandemic has had a significant impact on higher education institutions globally, together with the wellbeing, social life, and study experiences of students (Goldstone & Zhang, 2022; Hordosy & McLean, 2022; Maslimova et al., 2022), and academic staff (Gilbertson, 2020; LUSA, 2020). This chapter describes a review of the Masters program in Educational Leadership and Management at the Faculty of Education, University of Malta. While acknowledging the need to better understand the impact of the pandemic – personally and professionally – the focus was to develop a program that helped staff and mature students develop, through a different learning and lived experience, by cultivating the values that are central to the program, namely community, agency, sharing, collaboration, collegiality, voice, reflection, and inquiry. Ultimately, the scope of this chapter is to highlight how the pandemic has helped to renew the graduate program in a way that forged the wellbeing of the academic staff, the leaders of the various educational institutions, and students.

Abstract
Purpose
Mental health champions (MHCs) and young health ambassadors (YHAs) are two innovative public health interventions. MHCs are practitioners who work in schools and other youth settings and aim to be the “go to” person for mental health in these settings. YHAs are a linked parallel network of young people, who champion mental health and advocate for youth involvement, which was co-produced with young people across all stages of development implementation. This paper aims to identify the potential benefits, barriers and facilitators of these interventions.
Design/methodology/approach
Semi-structured qualitative interviews (n = 19) were undertaken with a purposive sample of n = 13 MHCs, and n = 6 YHAs, between June 2021 and March 2022. Interviews were audio-recorded, transcribed, anonymised and then analysed following a thematic approach. Ethical approval was granted by Newcastle University’s Faculty of Medical Sciences Ethics Committee.
Findings
The findings are organised under five key themes: motivating factors and rewards for MHCs and YHAs; outcomes for children and young people (CYP) and others; impact on youth settings and culture; facilitators of successful implementation; and implementation challenges and opportunities.
Practical implications
These findings are intended to be of relevance to practice and policy, particularly to those exploring the design, commissioning or implementation of similar novel and low-cost interventions, which aim to improve mental health outcomes for CYP, within the context of youth settings.
Originality/value
The interventions reported on in the present paper are novel and innovative. Little research has previously been undertaken to explore similar approaches, and the individual experiences of those involved in the delivery of these types of interventions.

Abstract
Purpose
The main objective of this article is to visualize the structure and trends of pro-environmental behavior (PEB) between 1999 and 2023 through mapping and in-depth analysis. The aim is to analyze PEB, which has received considerable academic attention in recent years due to its key role in the conservation of the environment and the protection of local communities in tourist destinations. This paper provides an important summary of the recent research that has explored the role that tourists have in protecting the environment through PEB.
Design/methodology/approach
This study presents a visual analysis of 2005 scholarly articles between the years 1999 and 2023 related to PEB. Using the knowledge mapping based on VOSviewer it presents the current status of research, which includes the analysis of citation analysis, co-citation analysis, co-citation network and longitudinal analysis.
Findings
PEB is an emerging topic due to its relevance to protecting the environment in the context of travel. The citation and co-citation analysis show the relevance of the behavior of tourists with regard to protecting the environment. The co-word analysis highlights the current significance of research concerning green hotels and the destination image of environmentally responsible destinations.
Originality/value
This study sheds light on the current research progress of PEB in the context of tourism through a comprehensive analysis (citation, co-citation and co-word). In addition, we provide theories and factors that have been previously used to study PEB in the context of tourism. The findings contribute to a broad and diverse understanding of the concept of PEB, which can provide important insights for policymakers in formulating management strategies and policies aimed at reducing environmental impacts in destinations.

Abstract
The Central Electricity Research Laboratories (CERL) at Leatherhead is the largest and longest established of the research centres of the Central Electricity Generating Board. Its staff numbers about seven hundred, three hundred of whom are professional scientists, and their programmes cover research into generation of electricity by coal‐ and oil‐fired power stations, and into transmission and distribution. CERL's activities include those as diverse as magneto‐hydrodynamics and the microbiology of soils; the dispersion of plumes from high chimneys and the basic physics of brittle fracture in metals. Three quarters of its work and almost all the corrosion research relates to generating electricity, although it has some of the best facilities in the world for studying the transmission of electricity at very high voltages, and the first corrosion problem it tackled was on steel cored aluminium conductors.
