Many schools see it as part of their mission to provide character education or moral education to their students. Yet many students with disabilities are excluded from these curricula, programs, and policies or denied some of their benefits. This essay explores some specific moral problems and obstacles that disabled students face when it comes to developing or exercising virtues of justice or fairness, self-respect, and self-development. For example, students with disabilities face moral questions about whether and how to request accommodations for their disability, whether to exercise special privileges that they suspect are not necessary to accommodate their disability on particular occasions, what to do when teachers do not provide them with accommodations they need, and how to respond to bias and discrimination directed at those with disabilities. This essay also uses John Rawls' theory of moral development to consider some of the ways in which schools are impeding or failing to promote the overall character development of disabled students.

Ensuring tritium fuel self-sufficiency while maintaining continuous and high-specification fuel flow to the tokamak via a low tritium inventory and controllable fuel cycle is a significant challenge to the STEP plant design. Effective and high-quality fuelling and exhaust design is required to sustain and control a stable plasma, whereas fuel sufficiency is required to prevent depletion of available tritium supply. Concerns regarding the lack of tritium availability preventing continuous tritium import are countered by breeding, where highly energetic neutrons from the core fusion reactions interact with lithium atoms suspended in the surrounding breeder blanket to produce tritium. The compact nature of STEP prohibits the integration of inboard breeder blankets posing a significant challenge for the design team looking to ensure more tritium is bred and made available than consumed within the core plasma. This paper outlines how purposeful technology selection and system architecting has converged on the outline of a conceivable and tritium-capable fuel cycle and breeder blanket design. Before introducing the STEP fuel cycle design outline and summarizing the approach undertaken to address the challenges facing plasma fuelling, key aspects of fuel self-sufficiency are discussed. This includes discussing a proposed helium-cooled liquid lithium breeder blanket and possible technology options for tritium extraction from lithium. Lastly, there is a brief process modelling overview, which emphasizes the central contribution of various employed modelling methods. Reflections on the presented fuel cycle design outline conclude that substantial development work is still required to realize a continuous tritium fuel cycle design and overcome the major challenges posed by tritium and lithium handling. Reflections on the presented breeder blanket design proposal conclude that while many substantial risks and blockers remain to achieve fuel self-sufficiency, high breeding ratios are expected to be achievable with a compact spherical tokamak configuration. Nonetheless, it is recognized that further consideration is required to ensure that the selection of liquid lithium as a breeder medium provides the overall simplest route to a self-sufficient and realizable design.

The article presents the discussion on providing a thought-provoking review of the ethical issues surrounding Whole-Eye Transplantation (WET). Topics include expanding on three of the concerns they raise in the context of disability bioethics to articulate priorities for future debate as WET evolves from experimental procedure to clinical practice; and personal enhancements in line with a medical model of disability while also pursuing status enhancements.
