Gambling is well-recognised as a significant public health threat. However, current responses to gambling still primarily focus on individualised responsible gambling paradigms, which neglects to consider the range of commercial and political determinants that contribute to gambling harm and how it might influence young people's gambling attitudes and consumption intentions. This includes the marketing tactics used by the gambling industry to normalise harmful gambling products as embedded in everyday life, including in sport. Young people have demonstrated an in-depth gambling brand awareness and can even recall specific strategies used in gambling advertising that might appeal to children. There have been continuous calls for action to protect children and young people from the commercial marketing of gambling products from a range of stakeholders, including young people and their parents. Young people and their parents are very supportive of increased regulations on gambling advertising, particularly during sport, and have called for sporting teams and codes to reject sponsorship deals with gambling companies. However, a heavy reliance on industry self-regulation has meant that governments across the world have decided that the costs associated with exposing children and young people to pervasive gambling marketing are outweighed by perceived benefits that gambling provides to businesses benefiting financially from gambling. Comprehensive curbs on marketing, as seen in tobacco, are required to significantly reduce young people's exposure to gambling advertising and ultimately prevent the next generation of harm.

The purpose of this research is to study the dynamic behavior of hydrostatic squeeze film dampers made of four hydrostatic pads, fed through four capillary restrictors with micropolar lubricant.

The modified version of Reynolds equation is solved numerically by the finite differences and the Gauss–Seidel methods to determine the pressure field generated on the hydrostatic bearing flat pads. In the first step, the effects of the pad dimension ratios on the stiffness and damping coefficients are investigated. In the second step, the damping factor is evaluated with respect to the micropolar properties.

The analysis revealed that the hydrostatic squeeze film dampers lubricated with micropolar lubricants produces the maximum damping factor for characteristic length of micropolar lubricant less than 5, while the same bearing operating with Newtonian lubricants reaches its maximum damping factor at eccentricity ratios larger than 0.4.

The results obtained show that the effects of micropolar lubricants on the dynamic performances are predominantly affected by the pad geometry and eccentricity ratio.

Initiating a practical model for embedding transformative learning in education that will promote sustainable development is a challenge for higher education. Siam University decided to assign a task force with the mission to work with communities in order to propose guidelines of learning for sustainability (LfS) based on real-life experiences. Selected communities which have agreed to be the community living labs for teaching and learning activities of the university were chosen based on the Bray and Thomas’ Cube Model. There are differences in sizes (number of members), locations (urban, suburban), and histories (old settlement with long history and rich culture and the newly settlement communities consisting of migrated members). Community-based participatory research (CBPR) was applied in the study. The initial model was developed from the synthesis of experiential work with communities in sustainability-related projects. After revision, the “Learning for Sustainability Action Model” was proposed. Success factors in implementing the model were also suggested.

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.

Literature has recognised entrepreneurship education as the main conduit through which entrepreneurial behaviours, attitudes and actions can be built, enacted and delivered. Since the founding of new ventures is largely a resourceful founder-driven enterprise, entrepreneurship education has largely centred on galvanising and shifting the mindsets and cognition of the entrepreneur. Yet, despite over 60 years of delivering entrepreneurship education programmes, hard evidence of the generation of high-growth-oriented and sustainable ventures has been scarce as student entrepreneurship intentions do not always translate into successful venture creation. This is largely because of the complexities of the practicality of entrepreneurial education particularly, the dissonance between acquired education in business schools and the knowledge and competencies needed in the entrepreneurial field. Such dissonance can be attributed to the lack of clarity on the pedagogical approach that most resonates with entrepreneurial action, the diversity in assessment methods and the scholarly illusion pertaining to how pedagogical approaches can be channelled to the generation of growth-oriented ventures. Drawing on Girox's concepts of transformative critical pedagogy (including pedagogy of repression), Socratic dialogue, Hegelian dialectic and Yrjö Engeström's transformative expansive agency, I demonstrate how a flipped transformative critical pedagogy can be harnessed in digitally enhanced learning environments to create new entrepreneurial possibilities for facilitating critical inquiry, complex problem-solving, innovation for the market and fostering tolerance for failure in ambiguous entrepreneurial contexts.

David Maines established himself as one of the premier symbolic interactionists who did not attach himself to any particular interactionist school of thought. In creating an extensive and intensive legacy via his publications, Maines looked into issues that other interactionists, bound to particular schools of thought, either took for granted or neglected to examine. In so doing, Maines resembled Simmel's Stranger not only as one who fits into a community but also as one who remains distant from the community. One of the key areas of investigation that defined Maines' work and that separated him from other interactionists pertained to his interest in social structure and specifically, how people become structurally situated as social-structural interactors. This chapter examines, in detail, Maines' interest in getting structurally situated and uses a television series, Dopesick, to discuss the relationships between institutional actors as a way to substantiate Maines' theoretical interest in social structure and the activities involved in the process of getting structurally situated.

Due to high speeds, heavy loads, large slide-to-roll ratios (SRR) and other variable operating conditions, some rolling bearings that have been working in harsh conditions may experience flash temperatures in the contact area, which may result in early damage like smearing and then affect service life. This study aims to investigate the flash temperature phenomenon of rolling bearings through theoretical and experimental analysis.

A technology for measuring temperature distribution in rolling ball on disk contact under lubrication was developed. The test-rig can simulate the ball bearing contact. The effects of working conditions such as entrainment speed, load, SRR and lubricating oil viscosity on the flash temperature were investigated.

The results of the theoretical calculation and experiments indicate that the parameters promoting the reduction of film thickness in elastohydrodynamic lubrication are always related with the number of flash points, even film thickness reduced to mixed lubrication. The flash temperature is easier to happen in conditions of high SRR, heavy load, slow entrainment speed and low viscosity oil.

This work conducts an experimental study on the flash temperature phenomenon, providing a test technology for bearing lubrication and failure investigation.
