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 oneβs 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
