    On a Classification of Irreducible Almost Commutative Geometries, A Second Helping

    Full text link
    We complete the classification of almost commutative geometries from a particle physics point of view given in hep-th/0312276. Four missing Krajewski diagrams will be presented after a short introduction into irreducible, non-degenerate spectral triples.Comment: 11 page

    Tools for second language support

    Get PDF
    The second language problem is the context in which non-native English speakers are required to interact with English-based computer systems. In other papers, we have characterized this setting and proposed methods of supporting such users. The present paper details several tools that we have developed to assist in our work with second language support. A prime consideration in such tool development is to facilitate easy management of alternative language resources. The need for criteria to direct second language support and the role of such tools in helping to evaluate such criteria is detailed here

    Helping students learn to spell : a look inside a second grade classroom

    Get PDF
    Learning how to spell is a complex, developmental process. This research paper describes how second grade students improved their spelling development in the context of daily reading and writing. Realizing that instruction in spelling patterns and strategies is needed for most students, this paper describes how instruction was based upon the results of the Developmental Spelling Test and the students\u27 writing samples. Four case studies will be presented in order to provide an in-depth look at the improvements that were demonstrated by the class as a whole

    Thermodynamics of flat FLRW universe in Rastall Theory

    Get PDF
    In this paper, after referring to the Rastall theory, we address some of its cosmological consequences. Moreover, bearing the Clausius relation in mind, using Friedman equations in Rastall theory and the Cai-Kim temperature, we obtain a relation for the apparent horizon entropy of a flat FLRW universe. In addition, we impose the entropy positivity condition on the obtained relation for the horizon entropy, to find some constraints on the Rastall parameters. Moreover, we investigate the second and generalized second laws of thermodynamics. The results of considering a dominated prefect fluid with constant state parameter are also addressed helping us familiarize with the Rastall theory.Comment: Considering arXiv:1606.06589 and arXiv:1607.04383, the paper has been revised and correcte

    Promoting inquiry skills in Curriculum for Excellence in Science: conceptualising inquiry to improve practice

    Get PDF
    This paper describes a Scottish initiative (arising out of a EU funded development project) involving university researchers, a local authority curriculum development officer and a group of teachers interested in developing more inquiry based approaches in science education. The project is not one in which the researchers bring prescriptions from research. Rather, it is seen as a joint effort aimed at solving practitioners' conceptual and practice issues. The overall question for the teachers was, How do I (we) make our practice more inquiry based? The question for the researchers was, How do we help you (the interested science teachers) to make your practice more inquiry based? This has two sub-questions: How do we help you to conceptualise the issues? How do we help you to solve the practice problems? As it turned out, the particular group of teachers we worked with did not ask for help with practice issues, so we have not made much progress in answering the second question. Therefore, this paper will focus on the first. We seem to have been successful in helping the teachers to acquire some useful conceptual tools for thinking about and changing their practice in ways that they valued for themselves. Perhaps the answer to the second question is that researchers can help teachers to solve their practice problems by helping them to conceptualise the issues

    Dollar Shortages and Crises

    Get PDF
    Emerging markets do not handle adverse shocks well. In this paper, I will outline an explanation of why emerging markets are so fragile, and why they may adopt contractual mechanisms -- such as a dollarized banking system -- that increase their fragility. I draw on this analysis to explain why dollarized economies may be prone to dollar shortages and twin crises. The model of crises described here differs in some important aspects from what is now termed the first, second, and third generation models of crises. I then examine how domestic policies, especially monetary policy, can mitigate the adverse effects of these crises. Finally, I will ask if there is a constructive role for international financial institutions both in helping to prevent the crises and in helping resolve them.

    Emerging markets do not handle adverse shocks well. In this paper, we lay out an argument about why emerging markets are so fragile, and why they may adopt contractual mechanisms—such as a dollarized banking system—that increase their fragility. We draw on this analysis to explain why dollarized economies may be prone to dollar shortages and twin crises. The model of crises described here differs in some important aspects from what are now termed the first-, second-, and third-generation models of crises. We then examine how domestic policies, especially monetary policy, can mitigate the adverse effects of these crises. Finally, we consider the role, potentially constructive, that international financial institutions may undertake both in helping to prevent the crises and in helping to resolve them.

    Half-Heard Voices of the Primal Zone; Sleep and Waking in a Poem by Cao Shuying

    Full text link
    Initially touching artifacts and sculpture from ancient Greece, and the risk of misreading thought or emotion cross-culturally, this essay draws briefly on Wordsworth’s testimony that poetic process arises first in a primally sensual and pre-verbal zone. The essay then proposes that similar practice, carried by craft and poetic experience in the target language, may be equally advantageous in poetry translation, while helping bridge individual and cross-cultural differences. In light of this, the essay’s second half addresses translational details in rendering Cao Shuying’s poem “I Often Read, Early Mornings.

    Experimental evidence for kin-biased helping in a cooperatively breeding vertebrate

    Get PDF
    The widespread belief that kin selection is necessary for the evolution of cooperative breeding in vertebrates has recently been questioned. These doubts have primarily arisen because of the paucity of unequivocal evidence for kin preferences in cooperative behaviour. Using the cooperative breeding system of long-tailed tits (Aegithalos caudatus) in which kin and non-kin breed within each social unit and helpers are failed breeders, we investigated whether helpers preferentially direct their care towards kin following breeding failure. First, using observational data, we show that not all failed breeders actually become helpers, but that those that do help usually do so at the nest of a close relative. Second, we confirm the importance of kinship for helping in this species by conducting a choice experiment. We show that potential helpers do not become helpers in the absence of close kin and, when given a choice between helping equidistant broods belonging to kin and non-kin within the same social unit, virtually all helped at the nest of kin. This study provides strong evidence that kinship plays an essential role in the maintenance of cooperative breeding in this species

    Tom Brown’s schooldays: ‘sportsex’ in Victorian Britain

    Get PDF
    Thomas Hughes’ idealised vision of life at Rugby public school is one of the best-known novels in the English language. It was regarded from the outset as a founding text of ‘muscular Christianity’. Contrary to the intentions of its author, it helped to inaugurate the cult of ‘manly’ athleticism that swept through the English public schools in the second half of the nineteenth-century. I argue that the novel reveals tensions around gender and sexuality that were in play among public schoolboys during the second half of the nineteenth-century. These tensions exploded into full public view in the trial of Oscar Wilde in 1895 and were instrumental in helping to establish a structure of homophobia within homosocial settings that has lasted through to the present day
