Who is learning what from student evaluations of teaching?

Student evaluations of teaching (or SET) through anonymous survey forms are a consistent practice in higher education across the world yet research results vary considerably as to the reliability, validity and efficacy of SET. Nonetheless, the widespread use of SET for promotion and tenure decisions ensures that these results are high stakes for tertiary staff. The tension between the purposes of SET (to supposedly improve teaching) and the ramifications of SET results are explored. Staff and students tend to hold very different views of SET and the issue of maintaining high academic standards can be at risk. However, SET can be used as an opportunity for staff and students to work together on issues in teaching and learning that enhance quality for all concerned

Noh Creation of Shakespeare

This article contains select comments and reviews on Noh Hamlet and Noh Othello in English and Noh King Lear in Japanese. The scripts from these performances were arranged based on Shakespeare’s originals and directed on stage and performed in English by Kuniyoshi Munakata from the early 1980s until 2014. Also, the whole text of Munakata’s Noh Macbeth in English (Munakata himself acted as Macbeth and Lady Macbeth in one play) is for the first time publicized. The writers of the comments and reviews include notable people such as John Fraser, Michael Barrett, Upton Murakami, Donald Richie, Rick Ansorg, James David Audlin, Jesper Keller, Jean-Claude Saint-Marc, Jean-Claude Baumier, Judy Kendall, Allan Owen, Yoshio ARAI, Yasumasa OKAMOTO, Tatsuhiko TAIRA, Hikaru ENDO, Kazumi YAMAGATA, Hanako ENDO, Yoshiko KAWACHI, Mari Boyd, and Daniel Gallimore

Study of blood indices and high performance liquid chromatography (HPLC) in differentiation of β-thalassemia trait and iron deficiency anaemia

Background: Iron deficiency anemia (IDA) and beta thalassaemia trait (BTT) are two of the most common causes of microcytic anemia.It is essential to differentiate between the two, so as to avoid unnecessary iron therapy which is contraindicated in beta thalassaemia .We retrospectively evaluated the reliability of various indices for differential diagnosis of microcytosis and -TT in the same patient groups .Methods: A total of 200 patients were evaluated. We calculated 6 discrimination indices in all patients with anemia or suspected beta thalassemia. None of the subjects had  combined  IDA and -TT. The patient groups were evaluated according to  the Mentzer, Shine and Lal, England and Fraser,Srivastava, Green and King, Ricerca.Results: According to percentage correctly diagnosed criteria, Ricerca  and Mentzer  index are considered as the two best discrimination indices in differentiation between β thalassemia trait  and iron deficiency anaemia .Youden’s index showed the following ranking with respect to the indices’ ability to distinguish between -TT and IDA, Ricerca index >  Mentzer index > Green and King index >  Srivastava index >  Shine and Lal index > England and Fraser index.Conclusions: Ricerca  and Mentzer  index are considered as the two best discrimination indices in differentiation between β thalassemia trait  and iron deficiency anaemia.Keywords: Iron deficiency anemia (IDA) and beta thalassaemia trait (-TT)

Intellectual Character and the News Media Audience: the Role of Intellectual Virtue in Pursuing Successful Knowledge Claims

This thesis explores the role of the audience within contemporary news media and how individual epistemic agents can make knowledge claims based on news media outputs. The aim is to show that the news media‟s audience plays an active role in the inter-relationships between themselves, media practitioners and media organisations. Further, it is argued that individual epistemic agents, as members of the audience of the news media, must exercise intellectual virtues in order to make successful knowledge claims based on news media publications and to be an active audience. The First Chapter considers contemporary media ethics and shows that the audience has largely been viewed as passive and has been under-evaluated when compared to the inter-relationship between practitioners and media organisations. Chapter Two evaluates the role of truth in the news media and how this affects trust of the news media within society. The Third Chapter introduces virtue epistemology, an approach which seeks to address the weaknesses of foundationalist accounts of knowledge by appealing to the cultivation and development of intellectually virtuous character traits of virtue epistemic individuals as responsible inquirers. This thesis argues that the application of Linda Zagzebski‟s theory of virtue epistemology has significant advantages for agents seeking knowledge based on news media outputs. The Fourth Chapter explores the application of intellectual virtues to knowledge acquisition based on contemporary news media examples; and finds that the traits of open-mindedness, inquisitiveness, thoroughness, and intellectual carefulness are of particular benefit to the audience in making successful knowledge claims based on news media publications. The thesis is concluded by arguing that the audience, as individual epistemic agents within a democratic society, have an active role in interpreting and shaping news media publications

Mollusca of King Island

During the month of November, 1922, I spent some days on King Island visiting relatives, and took what opportunity offered to investigate the Mollusca. No really comprehensive list of the Island's shell fauna appears to have been published. In one of the early French expeditions in 1802 the Naturalists Peron and Lesueur made considerable collections, their take being worked up principally by Lamarck and Blainville. Some of the species described by Tenison- Woods in the seventies of last century were from the Island, and they and others appeared in his Census which was compiled in 1877. Some of these, however, have not been retaken and require confirmation. The late Professor Tate had a small parcel of King Island shells sent him by some correspondent, and they were recorded by Tate and May in their Revised Census, 1901. There also appeared in the Victorian nature publication, "The Wombat," Vol. V., page 35, 1902, a fairly long list containing 135 species. I collected at Currie Harbour, Surprise Bay, Fraser, and near "Grassy." The first two on the West Coast, and the others on the East

Relative cluster categories and Higgs categories with infinite-dimensional morphism spaces

Cluster algebras *with coefficients* are important since they appear in nature as coordinate algebras of varieties like Grassmannians, double Bruhat cells, unipotent cells, ... . The approach of Geiss-Leclerc-Schr\"oer often yields Frobenius exact categories which allow to categorify such cluster algebras. In previous work, the third-named author has constructed Higgs categories and relative cluster categories in the relative Jacobi-finite setting (arXiv:2109.03707). Higgs categories generalize the Frobenius categories used by Geiss-Leclerc-Schr\"oer. In this article, we construct the Higgs category and the relative cluster category in the relative Jacobi-infinite setting under suitable hypotheses. This covers for example the case of Jensen-King-Su's Grassmannian cluster category. As in the relative Jacobi-finite case, the Higgs category is no longer exact but still extriangulated in the sense of Nakaoka-Palu. We also construct a cluster character refining Plamondon's. In the appendix, Chris Fraser and the second-named author categorify quasi-cluster morphisms using Frobenius categories. A recent application of this result is due to Matthew Pressland, who uses it to prove a conjecture by Muller-Speyer.Comment: 44 pages, with an appendix by Chris Fraser and Bernhard Keller; v2: Corrections in abstract, references and addres

How many people are in the Ragman Roll?

In the previous two features of the month, John Reuben Davies explained the process by which the Ragman Rolls were produced and discussed the nature of the oaths taken by the men and women who submitted to King Edward I’s rule. In this feature and the features to follow, we will examine the people themselves whose names are recorded in this unique document. We will start by asking the question of just how many people are ‘in’ the Ragman Rolls. In this feature, we will focus on trying to ascertain exactly how many men and women swore fealty, and in some cases also performed homage, to King Edward in the Ragman Roll. Of course, it is worth keeping in mind that those swearing fealty were not the only people mentioned in the rolls – there were also the men acting as witnesses to their fealties. These witnesses could include ‘Scottish’ nobles like the earls of Angus and Dunbar or March, but most of them were Englishmen in the retinue of King Edward
