Revisiting the Chlorine Abundance in Diffuse Interstellar Clouds from Measurements with the Copernicus Satellite

We reanalyzed interstellar Cl I and Cl II spectra acquired with the Copernicus satellite. The directions for this study come from those of Crenny & Federman and sample the transition from atomic to molecular rich clouds where the unique chemistry leading to molecules containing chlorine is initiated. Our profile syntheses relied on up-to-date laboratory oscillator strengths and component structures derived from published high-resolution measurements of K I absorption that were supplemented with Ca II and Na I D results. We obtain self-consistent results for the Cl I lines at 1088, 1097, and 1347 A from which precise column densities are derived. The improved set of results reveals clearer correspondences with H2 and total hydrogen column densities. These linear relationships arise from rapid conversion of Cl^+ to Cl^0 in regions where H2 is present.Comment: 17 pp, 2 tables, and 3 figures, to appear in The Astrophysical Journa

Prevention of toxoplasmosis in pregnancy: knowledge of risk factors.

BACKGROUND: Infection with Toxoplasma gondii is common and usually asymptomatic, although it can have catastrophic consequences in a pregnant woman if passed to her developing fetus. Counseling of pregnant women about risk factor reduction may reduce the risk of congenital toxoplasmosis. This study was undertaken to assess and compare the knowledge of obstetricians and internists or family practitioners regarding well-established risk factors for toxoplasmosis infection. METHODS: The study surveyed 102 obstetricians, internists and family practitioners to assess their knowledge of risk factors for toxoplasmosis infection as well as their practices for primary prevention counseling of pregnant women. Responses were analyzed for differences. RESULTS: Obstetricians were more likely than internists or family practitioners to provide appropriate counseling on reducing the two most common risk factors for toxoplasmosis infection (undercooked meat consumption and gardening without gloves). However, over one quarter of all participants inappropriately advised pregnant women to avoid all cat contact. Obstetricians, internists and family practitioners were all likely to fail to identify undercooked meat consumption as the primary risk factor for toxoplasmosis transmission. CONCLUSIONS: Obstetricians appear to provide more appropriate counseling for primary prevention of toxoplasmosis than internists and family practitioners, but both groups of physicians inappropriately advised avoidance of all cat contact. Education of obstetricians, internists and family practitioners on risk factors for toxoplasmosis transmission is needed and may lower the rate of congenital toxoplasmosis as well as decrease the frequency of cat abandonment during pregnancy

Deconstructing the Psychopath: A Critical Discursive Analysis

She loved accidents: any mention of an animal run over, a man cut to pieces by a train, was bound to make her rush to the spot. The spectacle of the wounded body has always had its lurid attractions. Coverage of serial killings and graphic accounts of brutal murders by various media is part of our “spectacular” culture fascinated by violence and brutality. The television is often the site where private desire and public fantasy meet, and where the fascination regarding dangerous offenders is initiated and nurtured (Knox, 17–18; Lesser). The convening of the public around scenes of violence represents what Mark Seltzer terms the “wound culture,” a lethal space in which the public interest in scars and mutilated and opened bodies constitutes a collective fascination with the unbearable aspects of human life. Although television news coverage reports violence and atrocities of all kinds, movies are the main medium through which dangerous individuals are presented to the public. The serial killer and psychopathic representations of unexplained violence can be found in such films as Friday the 13th, Halloween, Cape Fear, The Silence of the Lambs, and The Texas Chainsaw Massacre (Sharrett; Schmid). The emphasis on the hidden danger of the psychopath has replaced the Western, with its more clear-cut images of the dangerous individual, as the most popular genre of film related to the body and to representations of bodily violence in our culture (Corkin). In effect, current horror movies, and their associated prequels and sequels, use an efficient mixture of gore and frightening scenes of psychopaths preying on the innocent that help fosters the socially constructed subjectivity of the dangerous individual (Schneider; Hare 1993, 25, 35–36, 85, 140, 178). In response to (and also in reaction against) the pervasive discourse of the monstrous and of human monsters as caricatures of madness and danger, the objective of this paper is twofold: first, to conduct a critical, Foucauldian analysis of the psychopath, based on a discursive analysis of psychiatric descriptions of psychopathy, and second, to deconstruct the mythic figure of the psychopath and therefore to shed light on the relationship between psychiatric power and the construction of so-called monsters and psychopaths. Our argument is that the construction of the psychopath, a historically ill-defined concept (Gough; Sutherland 1950b; Cleckley; Hare 1993), as the main figure of modern monstrosity, involves the elaboration of a technical-knowledge system that is capable of characterizing anyone who deviates from the norm as dangerous to persons and to society (Movahedi; Sutherland 1950a; Hare 1993, chapter 7). To be sure, scientific research has been carried out on the dangerous individual in captivity (Verschuere, Crombez, De Clercq, and Koster; Glueck, 66–70; Hare 1993), thereby linking psychopathy with biological dangerousness. But few have looked at psychopathy from a critical and discursive standpoint. That is, in this essay we examine the way in which the creation of monsters in an earlier age gave way to the scientific inquiry into the character of the dangerous individual in the modern age, creating what Michel Foucault has called a “system of thought” (Foucault 1994, 5–10). Most studies of psychopathy have viewed it as a medical problem (Harris, Skilling, and Rice; Black; Siever; Reid; Skodol), a philosophical problem of evil and responsibility (Benn; Ciocchetti; Stein), or as an individual problem, in some cases, with societal ramifications (Hare 1993; Black; Stout; Samenow). But the medical, philosophic, individual, and social studies of psychopathy have all refrained from characterizing psychopathy as part of a cultural matrix that heightens the public’s sense of the fear of criminality, the fear of the unknown, the fear of the unfamiliar, and the fear of cultural pollution (Hare 1993; Stout; Magid and McKelvey; Black; Harris, Skilling, and Rice, 200–201). Indeed, the study of psychopathy as a clinical reality remains reliant on two strands of thought that explicitly reject cultural, historical, philosophic, and linguistic analyses: (1) a belief that criminals choose to commit crimes, despite economic, personal, and psychological factors that may or may not influence their choices; and (2) a belief in scientific progress that relies on continuous conceptual changes regarding what constitutes behavioral abnormalities and..

New Discoveries in Planetary Systems and Star Formation through Advances in Laboratory Astrophysics

As the panel on Planetary Systems and Star Formation (PSF) is fully aware, the next decade will see major advances in our understanding of these areas of research. To quote from their charge, these advances will occur in studies of solar system bodies (other than the Sun) and extrasolar planets, debris disks, exobiology, the formation of individual stars, protostellar and protoplanetary disks, molecular clouds and the cold ISM, dust, and astrochemistry. Central to the progress in these areas are the corresponding advances in laboratory astro- physics which are required for fully realizing the PSF scientific opportunities in the decade 2010-2020. Laboratory astrophysics comprises both theoretical and experimental studies of the underlying physics and chemistry which produce the observed spectra and describe the astrophysical processes. We discuss four areas of laboratory astrophysics relevant to the PSF panel: atomic, molecular, solid matter, and plasma physics. Section 2 describes some of the new opportunities and compelling themes which will be enabled by advances in laboratory astrophysics. Section 3 provides the scientific context for these opportunities. Section 4 discusses some experimental and theoretical advances in laboratory astrophysics required to realize the PSF scientific opportunities of the next decade. As requested in the Call for White Papers, we present in Section 5 four central questions and one area with unusual discovery potential. We give a short postlude in Section 6.Comment: White paper submitted by the AAS Working Group on Laboratory Astrophysics (WGLA) to the PSF SFP of the Astronomy and Astrophysics Decadal Survey (Astro2010

Laboratory Astrophysics and the State of Astronomy and Astrophysics

Laboratory astrophysics and complementary theoretical calculations are the foundations of astronomy and astrophysics and will remain so into the foreseeable future. The impact of laboratory astrophysics ranges from the scientific conception stage for ground-based, airborne, and space-based observatories, all the way through to the scientific return of these projects and missions. It is our understanding of the under-lying physical processes and the measurements of critical physical parameters that allows us to address fundamental questions in astronomy and astrophysics. In this regard, laboratory astrophysics is much like detector and instrument development at NASA, NSF, and DOE. These efforts are necessary for the success of astronomical research being funded by the agencies. Without concomitant efforts in all three directions (observational facilities, detector/instrument development, and laboratory astrophysics) the future progress of astronomy and astrophysics is imperiled. In addition, new developments in experimental technologies have allowed laboratory studies to take on a new role as some questions which previously could only be studied theoretically can now be addressed directly in the lab. With this in mind we, the members of the AAS Working Group on Laboratory Astrophysics, have prepared this State of the Profession Position Paper on the laboratory astrophysics infrastructure needed to ensure the advancement of astronomy and astrophysics in the next decade.Comment: Position paper submitted by the AAS Working Group on Laboratory Astrophysics (WGLA) to the State of the Profession (Facilities, Funding and Programs Study Group) of the Astronomy and Astrophysics Decadal Survey (Astro2010
