The Higgs mechanism gives mass to Yang-Mills gauge bosons. According to the conventional wisdom, this happens through the spontaneous breaking of gauge symmetry. Yet, gauge symmetries merely reflect a redundancy in the state description and therefore the spontaneous breaking can not be an essential ingredient. Indeed, as already shown by Higgs and Kibble, the mechanism can be explained in terms of gauge invariant variables, without invoking spontaneous symmetry breaking. In this paper, we present a general discussion of such gauge invariant (...) treatments for the case of the Abelian Higgs model, in the context of classical field theory. We thereby distinguish between two different notions of gauge: one that takes all local transformations to be gauge and one that relates gauge to a failure of determinism. (shrink)

Purpose The purpose of this paper is to explore an emerging ethical theory for the Digital Age – Flourishing Ethics – which will likely be applicable in many different cultures worldwide, addressing not only human concerns but also activities, decisions and consequences of robots, cyborgs, artificially intelligent agents and other new digital technologies. Design/methodology/approach In the past, a number of influential ethical theories in Western philosophy have focused upon choice and autonomy, or pleasure and pain or fairness and justice. These (...) are important ethical concepts, but we consider “flourishing” to be a broader “umbrella concept” under which all of the above ideas can be included, plus additional ethical ideas from cultures in other regions of the world. Before explaining the applied approach, this study discusses relevant ideas of four example thinkers who emphasize flourishing in their ethics writings: Aristotle, Norbert Wiener, James Moor and Simon Rogerson. Findings Flourishing Ethics is not a single ethical theory. It is “an approach,” a “family” of similar ethical theories which can be successfully applied to humans in many different cultures, as well as to non-human agents arising from new digital technologies. Originality/value This appears to be the first extended analysis of the emerging flourishing ethics “family” of theories. (shrink)

Recognizing the importance of health‐promoting relationships in engaging people who are experiencing homelessness in care, most research on health clinics for homeless persons has involved some recognition of client–provider relationships. However, what has been lacking is the inclusion of a critical analysis of the policy context in which relationships are enacted. In this paper, we question how client–provider relationships are enacted within the culture of community care with people who are experiencing homelessness and how clinic‐level and broader social and health (...) policies shape relationships in this context. We explore these questions within a critical theoretical perspective utilizing a critical ethnographic methodology. Data were collected using multiple methods of document review, participant observation, in‐depth interviews and focus groups. The participants include both clients at a community health clinic, and all clinic service providers. We explore how clients and providers characterized each other as ‘good’ or ‘bad’. For providers, this served as a means by which they policed behaviours and enforced social norms. The means by which both providers’ and clients’ negotiated relationships are explored, but this is couched within both local and system‐level policies. This study highlights the importance of healthcare providers and clients being involved in broader policy and systemic change. (shrink)

Dark comedies invite us to laugh at something which is, at least ostensibly, not funny at all. They take an act or event that would, under most descriptions or presentations, invite pity or anger, and give it characteristics that invite amusement. It is essential to the humour of the kidnapping in The King of Comedy that it is a kidnapping. The immorality of this event is crucial to its humour.

ABSTRACTMany anti-bullying programmes use teachers in the critical role of provider, yet few trials focus on enhancing their ability to fulfil this role. As teachers’ readiness may impact on the ef...

Evidence-Centered Design (ECD) is a framework for the design and development of assessments that ensures consideration and collection of validity evidence from the onset of the test design. Blending learning and assessment requires integrating aspects of learning at the same level of rigor as aspects of testing. In this paper we describe an expansion to the ECD framework (termed e-ECD) such that it includes the specifications of the relevant aspects of learning at each of the three core models in the (...) ECD, as well as making room for specifying the relationship between learning and assessment within the system. The framework proposed here does not assume a specific learning theory or particular learning goals, rather it allows for their inclusion within an assessment framework, such that they can be articulated by researchers or assessment developers that wish to focus on learning.

particular, the class were fascinated by W's remark following 2.71 ('A picture can depict any reality whose form it has') namely "A picture, cannot however, depict its pictorial form: it displays it." (2.172) At this point I usually tell the story about the anthropologist who shows a polaroid photograph of a some local scene to members of the newly discovered tribe. They can't make head nor tail of it which surprises the anthropologist until he recalls W's remark at 2.172. The (...) problem the people are having is that they do not understand the conventions governing the organisation of colours on a photograph. They don't realise that the arrangement of coloured patches which they see on the two dimensional surface is ordered in such a way as to allow a three dimensional picture to be represented. (eg. distant objects occupy smaller areas on the two dimensional surface than objects which are Use the menu.. (shrink)
