    This paper is one of a series of similar analysis being made by the Botany Department of Butler University in a study of tree-pollen types from the peat bogs of Indiana. From this detailed study the forest types of Indiana succeeding the periods of glaciation to the present can be partially and fairly accurately reconstructed. The distribution and frequency of the plant life as determined from this study in turn serves as an index to the different climatic changes which followed the recession of the glacial periods. Indiana is particularly well adapted for this type of study. as the northern half of the State underwent three periods of glaciation, referred to as the Illinoian. the Early and the Late Wisconsin ice sheets, each of which left in its wake small lakes and kettle holes, some of which still remain as bodies of water and some of which have been completely filled or drained

    The present paper is another chapter in the study of vegetational history of the Vilas county, Wisconsin neighborhood, stressing this time the area immediately adjacent to Trout lake, which as a whole is controlled by Pinus, and revolved in a Pinus dominance to the present time

    Promoting inclusion oral-health:social interventions to reduce oral health inequities

    Get PDF
    The aim of this collection of papers is to provide the reader with a cogent understanding of the role of evidence in the development of social or community-based interventions to promote inclusion oral-health and reduce oral health, health, and psychosocial inequities. In addition, this material will include various methods used for their implementation and evaluation. At the outset, the reader will be offered a working definition of inclusion oral-health, which will be modelled on the work of Luchenski et al. [1]. The interventions described are theoretically underpinned by a pluralistic definition of evidence-based practice [2] and the radical discourse of health promotion as postulated by Laverack and Labonte [3] and others [4,5]. This Special Issue will consist of eight papers, including an introduction. The first three papers will examine the various sources of evidence used to transform top-down into bottom-up community-based interventions for people experiencing homelessness; people in custody and for families residing in areas of high social deprivation. The final four papers will report on the implementation and evaluation of social or community-based interventions. This collection of research papers will highlight the importance of focusing on prevention and the adoption of a common risk factor agenda to tackle oral health, health and psychosocial inequities felt by those most excluded in our societies

    Measuring large-scale structure with quasars in narrow-band filter surveys

    We show that a large-area imaging survey using narrow-band filters could detect quasars in sufficiently high number densities, and with more than sufficient accuracy in their photometric redshifts, to turn them into suitable tracers of large-scale structure. If a narrow-band optical survey can detect objects as faint as i=23, it could reach volumetric number densities as high as 10^{-4} h^3 Mpc^{-3} (comoving) at z~1.5 . Such a catalog would lead to precision measurements of the power spectrum up to z~3-4. We also show that it is possible to employ quasars to measure baryon acoustic oscillations at high redshifts, where the uncertainties from redshift distortions and nonlinearities are much smaller than at z<1. As a concrete example we study the future impact of J-PAS, which is a narrow-band imaging survey in the optical over 1/5 of the unobscured sky with 42 filters of ~100 A full-width at half-maximum. We show that J-PAS will be able to take advantage of the broad emission lines of quasars to deliver excellent photometric redshifts, \sigma_{z}~0.002(1+z), for millions of objects.Comment: Matches version published in MNRAS (2012
