    A New Species of Mnioes (Hymenoptera: Ichneumonidae) from the United States

    This is the first record of the genus Mnioes in the United States. Previously described species are all Neotropic. Townes described the genus in 1946, placing Lampronota? jircunda Cresson, 1874, and Meniscus ? orbitalis Cresson, 1874, in it. The new species described here has been collected from several areas in the United States. This study was made while the author was a graduate student at The University of Michigan, Ann Arbor, Michigan

    Non-linear density dependence in time series is not evidence of non-logistic growth

    No full text
    Time series of population density are often used to seek deviations from logistic regulation by testing for a non-linear decline in per capita growth rate with density. Here I show that this method fails when the interval between observations is not matched by the timing of density impacts on growth. Time series overestimate instantaneous density impacts at low density and underestimate them at high density. More generally, logistic growth produces a deterministically decelerating decline in per capita growth with density if the interval between measures of population size exceeds any lag in density response. Deceleration arises independently out of stochastic density fluctuations, and under-compensating regulation. These multiple influences lead to the conclusion that sequential density estimates provide insufficient information on their own to reveal the identity of non-logistic growth processes. They can yield estimates of density compensation, however, which may suggest time lags in density dependence. Analysis of an empirical time series illustrates the issues

    Teaching Physicians Procedural Skills at a National Professional Meeting

    Get PDF
    Background: Practicing physicians often wish to improve their procedural skills but have limited educational opportunities to do so. Description: To summarize the effects of two procedural workshops on participants’ confidence, proficiency, and practice patterns. Evaluation: Following completion of a skin biopsy or arthrocentesis workshop, participants completed a post-course and an 8-month follow up evaluation. Recipients of this training rated it highly and reported that following training they performed more procedures, referred less, and noted an increase in their confidence that was still evident eight months after the workshop. Conclusion: Skin biopsy and arthrocentesis/joint injection skills can be taught to practicing physicians in a workshop setting at national professional meetings. Key Words: clinical competence; internal medicine; teaching; educational measuremen

    A version of this paper was published as ""Victim-Offender Mediation in Alaska," Alaska Justice Forum 11(2): 1, 5–6 (Summer 1994).Victim-offender mediation programs provide an opportunity for victims to meet the offenders face-to-face in the presence of a trained mediator for the purpose of resolving the injury of the crime in some way. Mediation is offered as a diversion from the justice system which the offender may accept to avoid more formal adjudication. This paper describes a pilot victim-offender mediation program in Anchorage which involves juveniles accused of certain offenses and the victims of those crimes.Victim-Offender Mediation / Development / The Development of Victim-Offender Mediation in Anchorag
