    (excerpt) The cosmopolitan family Rhopalosmatidae is comprised of four genera and 37 species (Townes 1977, Goulet and Huber 1993, Fernandez and Sarmiento-M 2002, Lohrmann and Ohl 2007)

    Fatal anaphylactic sting reaction in a patient with mastocytosis

    Get PDF
    We report on a 33-year-old female patient with indolent systemic mastocytosis and urticaria pigmentosa who died of an anaphylactic reaction after a yellow jacket sting. As she had no history of previous anaphylactic sting reaction, there was no testing performed in order to detect hymenoptera venom sensitization. But even if a sensitization had been diagnosed, no venom immunotherapy (VIT) would have been recommended. It is almost certain that VIT would have saved her life and it is most likely that VIT is indicated in some patients with mastocytosis with no history of anaphylactic sting reaction. However, no criteria have been established in order to allow a selection of mastocytosis patients eligible for such a `prophylactic' VIT. Copyright (C) 2008 S. Karger AG, Basel

    Original Pennsylvania College Building

    Full text link
    At the corner of Washington and High Streets in Gettysburg, Pennsylvania stands a modest old house—an anachronism that somehow seems so fitting in a town of such rich history. In the foreground lies a fairly inconspicuous plaque with condensed text—easy to miss on a leisurely car ride past the antiquated structure. Casually passing by, residents and tourists alike might not give the house a second thought or reflect on its origins. Yet, were they to merely glance over the building‘s historic plaque, they would discover a building whose significance can hardly be overstated. This was the site of the original Gettysburg College—the legacy of an American pioneer, Samuel Schmucker.

Birkner \u2772 Hidden in Plain Sight is a collection of student papers on objects that are hidden in plain sight around the Gettysburg College campus. Topics range from the Glatfelter Hall gargoyles to the statue of Eisenhower and from historical markers to athletic accomplishments.

    Radiative nonrecoil nuclear finite size corrections of order α(Zα)5\alpha(Z \alpha)^5 to the Lamb shift in light muonic atoms

    Full text link
    On the basis of quasipotential method in quantum electrodynamics we calculate nuclear finite size radiative corrections of order α(Zα)5\alpha(Z \alpha)^5 to the Lamb shift in muonic hydrogen and helium. To construct the interaction potential of particles, which gives the necessary contributions to the energy spectrum, we use the method of projection operators to states with a definite spin. Separate analytic expressions for the contributions of the muon self-energy, the muon vertex operator and the amplitude with spanning photon are obtained. We present also numerical results for these contributions using modern experimental data on the electromagnetic form factors of light nuclei.Comment: 8 pages, 1 Figur

    First Report of Leptomantispa pulchella (Banks, 1912) (Neuroptera: Mantispidae) from Iowa

    An adult specimen of Leptomantispa pulchella (Banks) (Neuroptera: Mantispidae) was collected in southeast Iowa. Published records indicate the species is present in southwestern Canada and much of Central America, but this is the first published report of this species from Iowa

    Addiction, Social Interactions and Gender Differences in Cigarette Consumption

    This paper addresses the impact of addiction and social interactions on cigarette demand, controlling for demographic and socioeconomic factors. A Box-Cox double-hurdle model for the simultaneous decisions of how much to smoke and whether to quit smoking is estimated on individual data from the 2000 Italian “Health Status and Use of Health Services” survey. The model incorporates the fixed costs of quitting and allows for the analysis of the effects of addiction and within-household interactions on smoking participation and cigarette consumption. Estimation results show that the duration of the smoking habit, used as measure of addiction, significantly increases the level of cigarette consumption and lowers the probability of quitting. Within-household social interactions affect individual’s attitude toward smoking. Participation decision is significantly influenced by the presence of other smokers and individual cigarette consumption increases as the consumption of the peer-group grows. Finally, gender differences are formally tested to verify whether male and female sub-samples can be pooled or should be separately analyzed. The hypothesis of equal consumption parameters is clearly rejected, suggesting the opportunity of distinguishing the consumption patterns of men and women.cigarette consumption, social interactions, gender effects, double-hurdle models.

    The Problem Of The Exegesis In Creative Writing Higher Degree Programs

    Get PDF
    It has now become standard practice for there to be an exegetical component not only in creative writing PhDs, but also in Masters and even Honours dissertations. In this paper we will examine the main kinds of exegeses currently being submitted and discussed - including reflective/journal-based, 'theory' based, literary criticism, and historical or genre context - and attempt to evaluate their usefulness both for the student/writer and for the broader academic community. We will be exploring such questions as: does current learning theory support the reflective or self-critical approach? Are current exegetical models (particularly the literary criticism model) overly embedded in an English Department idea of writing and writing theory? Does creative writing need to establish its own critical discourse, particularly through the exegesis? What kinds of students are doing these exegeses and how does our understanding of their assumed knowledges impact on developing models for critical work? Does current exegetical practice contribute to a growing theory of creative writing

    Accented Body and Beyond: a Model for Practice-Led Research with Multiple Theory/Practice Outcomes

    Get PDF
    Dance has always been a collaborative or interdisciplinary practice normally associated with music or sound and visual arts/design. Recent developments with technology have introduced additional layers of interdisciplinary work to include live and virtual forms in the expansion of what Fraleigh (1999:11) terms ‘the dancer oriented in time/space, somatically alive to the experience of moving’. This already multi-sensory experience and knowledge of the dancer is now layered with other kinds of space/time and kinetic awarenesses, both present and distant, through telematic presence, generative systems and/or sensors. In this world of altered perceptions and ways of being, the field of dance research is further opened up to alternative processes of inquiry, both theoretically and in practice, and importantly in the spaces between the two

    Large-Scale Simulations of the Two-Dimensional Melting of Hard Disks

    Full text link
    Large-scale computer simulations involving more than a million particles have been performed to study the melting transition in a two-dimensional hard disk fluid. The van der Waals loop previously observed in the pressure-density relationship of smaller simulations is shown to be an artifact of finite-size effects. Together with a detailed scaling analysis of the bond orientation order, the new results provide compelling evidence for the Halperin-Nelson-Young picture. Scaling analysis of the translational order also yields a lower bound for the melting density that is much higher than previously thought.Comment: 4 pages, 4 figure
