Recent Arguments (recent + argument)
Selected AbstractsOntogenetically stable dimorphism in a lacertid lizard (Acanthodactylus boskianus) with tests of methodology and comments on life-historyBIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY, Issue 2 2009MERAV SEIFAN Recent arguments in the literature prompted us to compare methods for assessing sexual dimorphism in body proportions of lacertid lizards, using Acanthodactylus boskianus. Although expressing body-part measurements as proportional to head length was the most effective method, we recommend using trunk length for the baseline as a general method for lizards. We also argue that, when aiming to assess sexual dimorphism in body proportions of lizards, if the context is ecological, all available adults should be included. However, for morphology and taxonomy, small sub-samples of the largest individuals that maximally express their genetic morphological potential should be used. In A. boskianus, the sexual dimorphism of mensural characters in adults was typical: males were larger, with relatively larger head and appendages. However, the ontogeny of this dimorphism was unusual in that the differences existed already in youth and thereafter persisted isometrically. The sexual dimorphism of meristic characters was male-biased in numbers of femoral pores and of caudal vertebrae, and female-biased in numbers of ventral plates along the trunk and of precaudal vertebrae. Size dimorphism may conceivably play a role in sex recognition because two potential visual cues (i.e. size dimorphism and dichromatism) appear to complement each other. © 2009 The Linnean Society of London, Biological Journal of the Linnean Society 2009, 97, 275,288. [source] GRAMMATICAL THERAPY AND THE THIRD WITTGENSTEINMETAPHILOSOPHY, Issue 4-5 2008ROM HARRÉ Abstract: The argument for interpreting Wittgenstein's project as primarily therapeutic can be extended from the domain of intellectual pathologies that form the core of the Philosophical Investigations to the topics in On Certainty, carrying further Hutchinson's recent argument for the priority of therapy in Wittgenstein's project. In this article I discuss whether the line Hutchinson takes is extendable to the work of the Third Wittgenstein. For example, how does Wittgenstein's discussion of Moore's "refutation of idealism" in On Certainty work as therapy when we think of it in "practice" terms? What practice? I suggest a further, but more tentative, step applying the therapeutic idea to seemingly insurmountable practical problems, where method is also at issue. [source] The Multicenter Study of Epilepsy Surgery: Recruitment and Selection for SurgeryEPILEPSIA, Issue 11 2003Anne T. Berg Summary:,Purpose: Multiple studies have examined predictors of seizure outcomes after epilepsy surgery. Most are single-center series with limited sample size. Little information is available about the selection process for surgery and, in particular, the proportion of patients who ultimately have surgery and the characteristics that identify those who do versus those who do not. Such information is necessary for providing the epidemiologic and clinical context in which epilepsy surgery is currently performed in the United States and in other developed countries. Methods: An observational cohort of 565 surgical candidates was prospectively recruited from June 1996 through January 2001 at six Northeastern and one Midwestern surgical centers. Standardized eligibility criteria and protocol for presurgical evaluations were used at all seven sites. Results: Three hundred ninety-six (70%) study subjects had resective surgery. Clinical factors such as a well-localized magnetic resonance imaging (MRI) abnormality and consistently localized EEG findings were most strongly associated with having surgery. Of those who underwent intracranial monitoring (189, 34%), 85% went on to have surgery. Race/ethnicity and marital status were marginally associated with having surgery. Age, education, and employment status were not. Demographic factors had little influence over the surgical decision. More than half of the patients had intractable epilepsy for ,10 years and five or more drugs had failed by the time they initiated their surgical evaluation. During the recruitment period, eight new antiepileptic drugs were approved by the Food and Drug Administration for use in the United States and came into increasing use in this study's surgical candidates. Despite the increased availability of new therapeutic options, the proportion that had surgery each year did not fluctuate significantly from year to year. This suggests that, in this group of patients, the new drugs did not provide a substantial therapeutic benefit. Conclusions: Up to 30% of patients who undergo presurgical evaluations for resective epilepsy surgery ultimately do not have this form of surgery. This is a group whose needs are not currently met by available therapies and procedures. Lack of clear localizing evidence appears to be the main reason for not having surgery. To the extent that these data can address the question, they suggest that repeated attempts to control intractable epilepsy with new drugs will not result in sustained seizure control, and eligible patients will proceed to surgery eventually. This is consistent with recent arguments to consider surgery earlier rather than later in the course of epilepsy. Postsurgical follow-up of this group will permit a detailed analysis of presurgical factors that predict the best and worst seizure outcomes. [source] International Intervention and the Severity of Genocides and PoliticidesINTERNATIONAL STUDIES QUARTERLY, Issue 3 2005Matthew Krain This study examines the effectiveness of overt military intervention in slowing or stopping the killing during ongoing instances of genocide or politicide. Six alternative hypotheses regarding the potential effects of intervention on genocide/politicide severity are tested in a cross-national longitudinal analysis of all ongoing genodices or politicides from 1995 to 1997. The results suggest that interventions that directly challenge the perpetrator or aid the target of the brutal policy are the only effective type of military responses, increasing the probability that the magnitude of the slaughter can be slowed or stopped. Impartial interventions seem to be ineffective at reducing severity, and interventions to challenge the perpetrator do not make matters worse for the targets of genocide or politicide. The findings are consistent with recent arguments that attempts to prevent or alleviate mass killings should focus on opposing, restraining, or disarming perpetrators and/or removing them from power. [source] From Adam Swift to Adam Smith: How the ,Invisible Hand' Overcomes Middle Class HypocrisyJOURNAL OF PHILOSOPHY OF EDUCATION, Issue 4 2007JAMES TOOLEY This paper challenges Richard Pring's suggestion that parents using private education may be undermining the desire for social justice and equality, using recent arguments of Adam Swift as a springboard. Swift's position on the banning of private schools, which uses a Rawlsian ,veil of ignorance' argument, is explored, and it is suggested that, if equality of opportunity is a major aim, it does not go far enough by permitting parental partiality. If the only alternative is a Platonic state, then this may be acceptable. But a neglected third scenario, drawing on the insights of Adam Smith, shows ,self-love' to be a valuable social virtue, leading to a more favourable resolution of the ,paradox of the shipwreck' than that explored by Swift. Pointers are given to evidence from developing countries and a more detailed ,veil of ignorance' argument to support this case. [source] A Priori Knowledge: Debates and DevelopmentsPHILOSOPHY COMPASS (ELECTRONIC), Issue 3 2008C. S. Jenkins This paper takes a look at a variety of attempts to account for the apparent existence of a priori knowledge: knowledge that is independent of evidence from sense experience. The classic views can be helpfully classified in terms of three different responses they provide to a single key question. Recently Alan Gibbard and Hartry Field have made space for a fourth, ,evaluativist', response. I highlight a few difficulties faced by this new camp and indicate where I think a fifth camp can be set up. I conclude by discussing recent arguments due to John Hawthorne and Timothy Williamson to the effect that the a priori/a posteriori distinction is not (always) a helpful one to draw at all.
