Implications of Constraints on Mass Parameters in the Higgs Sector of the Nonlinear Supersymmetric SU(5) Model

The Higgs sector of the minimal nonlinear supersymmetric SU(5) model contains three mass parameters. Although these mass parameters are essentially free at the electroweak scale, they might have particular values if they evolve from a particular constraints at the GUT scale through the RG equations. By assuming a number of simple constraints on these mass parameters at the GUT scale, we obtain their values at the electroweak scale through the RG equations in order to investigate the phenomenological implications. Some of them are found to be consistent with the present experimental data.Comment: 23 pages, 10 figure

Failure to detect "cap" structures in mitochondrial DNA-coded poly(A)-containing RNA from HeLa cells

The structure of the 5'-termini has been investigated in mitochondrial DNA- coded poly(A)-containing RNA from HeLa cells. For this purpose, mitochondrial RNA isolated from cells labeled for 3 hours with [32P]orthophosphate in the presence of 20 µg/ml camptothecin, and selected for poly(A) content by two passages through oligo(dT)-cellulose, was digested either with the nuclease P1 or with a mixture of RNases: the digestion products were then fractionated by two-dimensional electrophoresis. No "cap" structures were detected under conditions where the presence of such structures in one out of five to ten RNA molecules would have been recognized. It is, therefore, likely that "cap" structures are completely absent in HeLa cell mitochondrial poly(A)-containing RNA

New Canadian Records of Asilidae (Diptera) From an Endangered Ontario Ecosystem

The Asilidae (Diptera) of Bosanquet (northern Lambton County, Ontario) are surveyed. Forty-one species are recorded. Twelve species are published for the first time from Canada: Atomosia puella, Cerotainia albipilosa, Cerotainia macrocera, Holcocephala calva, Holopogon (Holopogon) oriens, Laphria canis, Laphria divisor, Laphria grossa, Lasiopogon opaculus, Machimus notatus, Machimus sadyates, and Neomochtherus auricomus. These species plus the following four are new to Ontario: Laphystia flavipes, Lasiopogon tetragrammus, Machimus novaescotiae, and Proctacanthella ca­copiloga

Editorial introduction [to Strategic uncertainties: ethics, politics and risk in contemporary educational research]

Strategic Uncertainties: Ethics, Politics and Risk in Contemporary Educational Research offers new perspectives on contemporary educational research in a wide range of contexts and settings. The authors provide fresh insights into the ethics, politics and risks of educational research through their deployment of up-to-date concepts and methods. They also bring educational research ‘to life’ as a series of meaningful and significant issues and dilemmas, and by drawing on the voices of ‘real-life’ research participants and practitioners. In 2001, a theme issue of the Queensland Journal of Educational Research (Coombes & Danaher, 2001) was published under the title Cui Bono?: Investigating Benefits and Interests in Educational Research. In that issue, a group of authors from a range of academic disciplines explored the notion of who benefits from educational research and how such benefits might be identified, evaluated and weighed against potential costs to the research participants. The purpose of the contributors was not to view the intentions and results of research through rose-coloured glasses (‘everyone benefits and everyone is happy’) but to establish, as honestly as possible, whether the perceived benefits of a particular research project would actually occur without some cost to those involved. The key concepts, which were the focus of each article, were therefore the benefits and costs of educational research. In Strategic Uncertainties, the focus of attention shifts to the potential risks of educational research and to the strategies that researchers might employ to minimise or from some perspectives try to eliminate these risks (and from other perspectives to embrace and celebrate such risks). Educational research, by its very nature, is concerned with people; it cannot function in a sterile vacuum. Where people are concerned, complete agreement among the participants can never be guaranteed. Thus stakeholders may compete for powerful speaking positions. Research projects, though conceived with the best of intentions, may serve to highlight the gap between researcher and researched by reinforcing the socioeconomic and educational inequities of their relationships with one another. These particular risks, among many others, emphasise the ethical and political dimensions of relationships among the participants and subject to critical scrutiny claims that research projects confer particular kinds of benefits. Educational research is indeed a ‘risky business’, but this should not deter researchers from engaging in the practice. It is the purpose of Strategic Uncertainties to apply theoretically informed, methodologically rigorous and experientially grounded critique to the ‘murky shadows’ and ‘no-go areas’ of contemporary educational research. The title of this book, Strategic Uncertainties, is taken from the text of Ian Stronach and Maggie MacLure (1997), Educational Research Undone: The Postmodern embrace. The authors focused on postmodern researchers’ efforts to avoid being caught in the snares of: the binary oppositions that have traditionally promised the comforts of certainty in philosophical thinking – between reality and appearance, reason and superstition, causes and effects, meaning and language, identity and imposture, local and universal etc. – they choose not to choose between them, not to work to transcend them, nor, importantly, to ignore them, but instead to complicate the relations between them. (p. 5; emphasis in original) According to Stronach and MacLure (1997): The kind of opening which such work attempts is that of the rupture – or interruption and disruption – in the (uncertain) hope that this will generate possibilities for things to happen that are closed off by the epistemologies of certainty….These are uncanny openings, then. They rupture things, not in order to let the light pour in, but to make it harder to see clearly. They open spaces which turn out not to be spaces, but knots, complications, folds and partial connections. It is impossible even to tell for sure whether they are openings or closings, since they are also blocking manoeuvres, which would prevent escape routes to happy endings…We try to practise this kind of strategic uncertainty throughout, and within this book. Our aim is to mobilise meaning…rather than to fix it. (p, 5; emphasis in original; emphasis added) Elaborating and expanding on these propositions by Stronach and MacLure (1997), the content of Strategic Uncertainties is a set of accounts by contemporary educational researchers of the ethics, politics and risk of their own research projects. While those accounts draw on a multiplicity of theoretical, methodological and empirical resources to frame and inform their respective engagements with educational research, they have in common a general commitment to, and at the same time an ongoing interrogation of, the ideas encapsulated in the term ‘strategic uncertainties’
