Guidelines for peer observation of learning and teaching

These guidelines have been prepared as a starting point for schools of education or education departments wishing to undertake peer observation of learning and teaching, particularly as preparation for a Subject Review. While the guidelines are designed to have general applicability to any department, the particular circumstances and the requirements of specific subjects will almost certainly mean that there will be variations in practice between departments and subject area

Towards a Java Subtyping Operad

The subtyping relation in Java exhibits self-similarity. The self-similarity in Java subtyping is interesting and intricate due to the existence of wildcard types and, accordingly, the existence of three subtyping rules for generic types: covariant subtyping, contravariant subtyping and invariant subtyping. Supporting bounded type variables also adds to the complexity of the subtyping relation in Java and in other generic nominally-typed OO languages such as C# and Scala. In this paper we explore defining an operad to model the construction of the subtyping relation in Java and in similar generic nominally-typed OO programming languages. Operads, from category theory, are frequently used to model self-similar phenomena. The Java subtyping operad, we hope, will shed more light on understanding the type systems of generic nominally-typed OO languages.Comment: 13 page

Numerical modelling of stable minimal surfaces

This thesis examines the numerical representation of stable minimal surfaces. In particular, the work presented concentrates on the formulation of a finite element, suitable for the analysis of systems subjected to large strains and large displacements. In order to obtain an understanding of the physical properties of a minimal surface, and to verify the proposed numerical solution algorithms, the surfaces developed by several soap-film models are given. The mechanisms involved in the formation of a soap-film (minimal) surface is summarised. Several types of minimal surfaces are investigated, including general surfaces between rigid boundaries, single minimal surfaces between two frames, and those with internal and external flexible boundaries. In addition, the question of the stability of minimal surfaces is discussed, in terms of a finite and an infinitesimal perturbation. The numerical modelling of minimal surfaces is presented, based initially on the discretisation of the form using plane linear (line) and triangular elements. The application of the matrix-based element formulations to the vector-based Dynamic Relaxation solution algorithm is described. The formulations of the elements are assessed in the context of large strains and large displacements. Subsequently, the effects of the violations of the assumptions inherent in the derivation of the element stiffness matrices on the accuracy of the numerical solution are demonstrated, and measures proposed to maintain the stability of the solution algorithm. The numerical solutions to several minimal surfaces are provided, based on the linear and triangular element discretisations respectively. An intended improvement on the plane linear and triangular element formulations is proposed by the derivation of a higher order finite element. A 24 degrees-of-freedom finite element is formulated, representing a general curved elastic (or inelastic) geometrically non-linear continuum, and modelling the condition of plane stress. The element equations are derived with special consideration of the simulation of the effects of large strains and large displacements. An appraisal of the quality of the element formulation is made through the application of the Patch test and the Eigenvalue test. The solutions to several minimal surfaces are presented, from which the effects of the assumptions in the element formulation on the accuracy of the proposed numerical solution algorithm are demonstrated

Toward a Spectrum of Moral Harm: A New Paradigm

Moral harm is the pain, anguish, or trauma experienced as a result of violations to one’s value system. Researchers have analyzed the experience of moral harm through the lenses of moral injury among military personnel, and moral distress among helping professionals. Although both fields of research share similar frames of reference, the current project is the first known work to conceptualize moral injury and moral distress within the same theoretical model. The authors posit that moral injury and moral distress are experiences along a spectrum; both struggle and recovery can be understood within this context. Implications for ethical practice and future research are discussed

The Longitudinal Impact Of Moral Injury On Combat Soldiers: A Narrative Inquiry Study

This study explores the confluence of Narrative Inquiry\u27s three commonplaces of temporality, sociality, and place on the experiences of five combat veterans with combat-designated Military Occupational Specialties (MOS) across the lifespan. In particular, the study examines the longitudinal components of Moral Injury (MI) before, during, and after combat operations. Chapter 4 explores the individual narratives of the participants, Chapter 5 examines common narrative threads between participants, and Chapter 6 is the author\u27s subsequent extrapolations on the subject matter given his own experiences as a combat veteran of the Iraq War

The Tenure-Track Life: Experiences of New Faculty in Tenure-Track Positions

This study details the experiences of new faculty in tenure-track positions without prior experience in academia beyond the post-doctoral level. Semi-structured, qualitative interviews were conducted using phenomenological methodology with six faculty members meeting the criteria at a mid-sized, public institution in the southeastern United States with a reputation for academic excellence and a Research 2 (R2) Carnegie classification. Findings highlight the tension found between subcomponents of professorial life and the continued struggles of minority faculty. Implications for future research are given, to include the need for a deep exploration of the rhyme and reasons of the tenure process
