© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The idea that sociology has the status of a strict science—that is, that sociology, like mathematics, has at its disposal a well-founded, deductive system of propositions—is nowadays rejected even more by its pragmatic advocates than by its skeptical practitioners; it is refuted both by the arbitrary manipulation of sociology’s internally constitutive, theoretical interconnections at the hands of practical interests and technocratic utility, and by the resultant increasing relativization of its findings. However, as we shall see, the arbitrariness of the treatment (...) of sociology does not correspond with any arbitrariness in its object. On the contrary, with all empirical relativity a structural constancy persists in the agency constructing, comparing, and evaluating the experience of the everyday world, as well as scientific experience. This was precisely Kant’s discovery, that the conditions making possible our primary experience of objects must be, at the same time, the constitutive structure of the objects themselves, and also the framework for the scientifically systematic treatment of them, because otherwise there could be no knowledge in the sense of the structural identification of object, experience, and reflection. This Kantian principle guarantees, then, that sociology is indeed possible as a strict science; that is, it is completely possible as an integral, deductive aspect of theory, as long as we reconstruct, by means of axioms and postulates, the constitution of the object of theory out of the structure of our direct interpersonal experience. In this vein, Rene König, a pioneer in modern German social science, states. (shrink)

This study evaluated the integration of psychology ethics into an introductory psychology course. Students in two general psychology sections were exposed to an infusion of psychology ethics in teaching, research, and clinical practice, whereas students in two sections were exposed to traditional course content. Students completed a pre and post-test assessment including a psychology ethics questionnaire and open-ended responses to three ethics case studies. Students in the ethics group displayed a statistically significant increase in scores on both measures from pre (...) to post-test. However, students in the traditional group showed no improvement in scores. (shrink)

Analysis of the local implementation of paternity establishment and child support policy in four Wisconsin counties suggests that these policies reproduce some aspects of patriarchal gender relations. The counties' information-collecting practices focused on nonmarital mothers' sexual activity and nonmarital fathers' employment and income. Women were questioned far more extensively than men about their sexual practices and partners; women's accounts of their sexual activity were used to evaluate their overall truthfulness, and administrative practices in effect encouraged alleged fathers to state whether (...) they were convinced of the mother's sexual fidelity. By demonstrating the gendered nature of the terms under which public assistance is granted, the findings highlight the significance of the process of policy implementation for understanding the gendered character of state systems of social provision.

Der fünfte Band der Reihe trägt den Titel Ethik und Politik aus interkultureller Sicht. Neben einer begrifflichen, methodischen und inhaltlichen Klärung, was aus interkultureller Sicht bedeutet, werden in den verschiedenen Beiträgen ethische und politische Ansätze im heutigen Weltkontext der Philosophie erörtert. Interkulturell orientiertes philosophisches Denken weist alle Zentrismen zurück, ohne jedoch die jeweilige kulturelle Sedimentiertheit in Frage zu stellen. Folgerichtig wird so auch ein jeder Monismus abgelehnt. Das heutige Angesprochensein der Kulturen verlangt von uns, von den beiden Fiktionen einer totalen (...) Identität und völligen Differenz unter den ethischen und politischen Modellen Abschied zu nehmen. Die These von der Überlappung zielt auf das Wahrnehmen von grundsätzlichen Ähnlichkeiten und erhellenden Differenzen in den Ansätzen. Wer einen Pluralismus bejaht, muß auch bereit sein, im Geiste der Toleranz die unterschiedlichen Ansätze zur Ethik und Politik ernst zu nehmen. Wer den Konsens zu sehr betont, liebäugelt mit irgendeinem Identitätsmodell, vernachlässigt den Kompromiß. Tatsache ist jedoch, daß gerade Kompromisse zur Konfliktlösung beitragen. So sind die Beiträge dieses Bandes dem Ziel gewidmet, sowohl eine theoretische Begründung als auch eine praktische Bewältigung der interkulturellen Verständigung in Ethik und Politik zu leisten.

Genetic testing has familial implications. Counsellors find themselves in (moral) conflict between medical confidentiality (towards the patient) and a potential right or even duty to warn at-risk relatives. Legal regulations vary between countries. English literature about German law is scarce. We reviewed the literature of relevant legal cases, focussing on German law, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. This article aims to familiarise counsellors with their responsibilities, compare the situation between countries and point out (...) legally unresolved areas.According to the German Genetic Diagnostics Act (Gendiagnostikgesetz) in case of an ‘avoidable or treatable’ genetic disorder, geneticists ought to confine themselves to the obligated advice to the patient. Whether a breach of the duty of confidentiality can be justified in exceptional cases by ‘necessity as justification’ for actively informing relatives at risk remains legally unclear. In case of a ‘neither avoidable nor treatable’ genetic disease, geneticists should also refrain from actively informing relatives as the justifiable state of emergency does not permit to break the duty of confidentiality.

Numerous authors identify a white supremacist ideology that shapes the educational opportunities for racially diverse students. We contend that this ideology informs educational policy and hampers the likelihood that racially diverse populations can achieve success at levels similar to students of European descent. In this paper we define the white supremacist ideology as it informs education policy and practices. Three examples from the United States are then used to illustrate the influence of such an ideology. These examples include the creation (...) and protection of racially segregated schooling; desegregation policies; and the current uses of school report cards. We conclude with the relevance of this discussion to educational debates in Great Britain and South Africa, and recommendations to minimise the influence of this ideology on education policy and school reform efforts.

When external groups accuse a business organization of unethical practices, managers of the accused organization usually offer a communicative response to attempt to protect their organization's public image. Even though many researchers readily concur that analysis of these communicative responses is important to our understanding of business and society conflict, few investigations have focused on developing a theoretical framework for analyzing these communicative strategies used by managers. In addition, research in this area has suffered from a lack of empirical investigation. (...) In this paper we address both of these weaknesses in the existing literature. First, we explicate Impression Management Theory as an appropriate framework for studying organizational communicative responses, paying particular attention to the concept of accounts. Second, we critique previous investigations of organizational accounts and discuss the major contributions of our study. Third, we propose a coding system and content analyze the accounts offered by managers from 21 organizations that were recently the targets of consumer boycotts. Finally, we report the results of our empirical investigation and discuss ethical issues related to organizational accounts. (shrink)

The theologian Hugo Rahner argued that the homo ludens is a man of ‘Ernstheiterkeit’, a person who can smile under tears but also recognizes the gravity in all earthly cheerfulness. The primary aim of this study was to test the validity of this notion: Do homines ludentes exist? Two hundred sixty-three adult subjects were measured for seriousness and cheerfulness and playfulness. Results provided unequivocal support for Rahner's thesis. Numerous subjects scored high in both seriousness and cheerfulness thus confirming the existence (...) of homines ludentes. It was further found that these subjects were among those scoring highest in playfulness. Subjects scoring high in cheerfulness but low in seriousness were, however, even more closely associated with playfulness. The scores for homines ludentes did not differ from the rest of the subjects in the creative and dynamic facets of playfulness. The importance of developing empirical research to investigate hypotheses derived from non-scientific concepts is discussed. (shrink)

Each state’s Medicaid Fraud Control Unit prosecutes billing fraud cases against individual healthcare providers who fraudulently bill Medicaid for services provided. Once an individual is convicted of billing fraud, the Office of Inspector General for the Department of Health and Human Services may exclude the individual from billing any federal government healthcare program, including Medicaid. Excluded individuals are added to a public list of exclusions, which restricts their ability to practice professionally. Prompted by criminology research into the impact of policing (...) resources, we test whether these government enforcement initiatives against fraud serve as a deterrent to would-be fraudulent billers. We document that key enforcement proxies, the staffing level and budget of an MFCU, are positively associated with the yearly number of exclusions added at the state level. Our results are consistent with the exclusion list not being a deterrent but provide support for MFCUs’ fraud detection efforts. This paper provides industry-specific fraud insights for auditors and other individuals involved in public policy, specifically Medicaid, and introduces a novel dataset to the accounting fraud research literature.

Background: Treating medication-refractory freezing of gait in Parkinson’s disease remains challenging despite several trials reporting improvements in motor symptoms using subthalamic nucleus or globus pallidus internus deep brain stimulation. Pedunculopontine nucleus region DBS has been used for medication-refractory FoG, with mixed findings. FoG, as a paroxysmal phenomenon, provides an ideal framework for the possibility of closed-loop DBS.Methods: In this clinical trial, five subjects with medication-refractory FoG underwent bilateral GPi DBS implantation to address levodopa-responsive PD symptoms with open-loop stimulation. Additionally, PPN (...) DBS leads were implanted for CL-DBS to treat FoG. The primary outcome of the study was a 40% improvement in medication-refractory FoG in 60% of subjects at 6 months when “on” PPN CL-DBS. Secondary outcomes included device feasibility to gauge the recruitment potential of this four-lead DBS approach for a potentially larger clinical trial. Safety was judged based on adverse events and explantation rate.Findings: The feasibility of this approach was demonstrated as we recruited five subjects with both “on” and “off” medication freezing. The safety for this population of patients receiving four DBS leads was suboptimal and associated with a high explantation rate of 40%. The primary clinical outcome in three of the five subjects was achieved at 6 months. However, the group analysis of the primary clinical outcome did not reveal any benefit.Interpretation: This study of a human PPN CL-DBS trial in medication-refractory FoG showed feasibility in recruitment, suboptimal safety, and a heterogeneous clinical effect in FoG outcomes.

Drawing on the empirical premise that attention makes objects look more intense, Ned Block has argued for mental paint, a phenomenal residue that cannot be reduced to what is perceived or represented. If sound, Block's argument would undermine direct realism and representationism, two widely held views about the nature of conscious perception. We argue that Block's argument fails because the empirical premise it is based upon is false. Attending to an object alters its salience, but not its perceived intensity. We (...) also argue that salience should be equated with mental primer, a close cousin of mental paint that reintroduces difficulties for direct realism and representationism. The upshot is that direct realism and representationism are still in trouble, but not for the reason that Block thinks. (shrink)

In the expanding repertoire of practices designed to increase the supply of organs for transplantation, non-heart-beating cadaver organ donation has generated an ongoing debate in the literature. The continuing stream of articles is disquieting in part because it documents a troubling "trial-and-error ethics" approach to the formulation of organ procurement policy, and because it raises serious questions about the reasons that the development of this policy is being mediated by published communication. In the light of concerns about the implicit support (...) and credibility that professional publications give to organ procurement policies, restraint in publishing articles about non-heart-beating organ donation as well as in devising such policies is strongly advocated.

Approximately one in 10 children in foster care are medically complex and require intensive medical supervision, frequent hospitalization, and difficult medical decision making. Some of these children are in foster care because their parents cannot care for their medical needs; other parents are responsible for their child’s medical needs due to abuse or neglect. In either case, there can be uncertainty about the role that a child’s biological parents should play in making serious medical decisions. Here we highlight some of (...) the ethical challenges inherent in making these decisions for children in foster care, as seen through the lenses of a child welfare provider, an inpatient care physician, and a primary care pediatrician.

Many recent gene knockout experiments cause anatomical changes to the jaw region of mice that several investigators claim are evolutionary reversals. Here we evaluate these mutant phenotypes and the assertions of atavism. We argue that following the knockout of Hoxa-2, Dlx-2, MHox, Otx2, and RAR genes, ectopic cartilages arise as secondary consequences of disruptions in normal processes of cell specification, migration, or differentiation. These disruptions cause an excess of mesenchyme to accumulate in a region through which skeletal progenitor cells usually (...) migrate, and at a site of condensation that is normally present in mammals but that is too small to chondrify. We find little evidence that these genes, when disrupted, cause a reversion to any primitive condition and although changes in their expression may have played a role in the evolution of the mammalian jaw, their function during morphogenesis is not sufficiently understood to confirm such hypotheses.

This article analyzes U.S. court cases involving reproductive technologies in terms of their implications for reproductive choice, mothers' versus fathers' rights, definitions and evaluations of parenting, and the nuclear family structure. The analysis reveals that the courts have tended not to recognize how social conditions shape women's reproductive choices, to promote fathers' rights more than mothers' rights, to ignore the social relationships that constitute childbearing and child rearing and value men's over women's biological contribution to these processes, to reflect certain (...) assumptions about the proper roles of mothers and fathers, and to privilege the nuclear family. The implications of developing reproductive technology policy for an understanding of the relationships among gender, reproductive technologies, and the state are considered, and recommendations for the equitable regulation of these technologies are offered.

We argue that Benenson et al. need to consider not only sex differences in the effects of care on offspring survival but also in age-specific fertility when predicting how longevity affects fitness. We review evidence that staying alive has important effects on both women's and men's fitness, and encourage consideration of alternative explanations for observed sex differences in threat responses.

Manifeste de la philosophie cartésienne, le Discours de la méthode (1637) est tout à la fois le récit d'un cheminement intellectuel et l'illustration magistrale d'un projet : fonder l'unité des sciences et constituer une science universelle. Foyer d'une oeuvre foisonnante, le Discours revendique les droits de la raison contre toute tradition et toute autorité. C'est pourquoi il assigne à la philosophie une tâche : s'élever à 1a certitude. La présente édition, augmentée d'un dossier, entend mettre en évidence le jeu de (...) résonances qui relie le Discours aux autres textes de Descartes. (shrink)
