Necessary a Posteriori Identity Truths: Fregeanism Beats Direct Reference Theory

I argue that Fregeanism with respect to proper names—the view that modes of presentation are relevant to the contents of proper names—is able to account for the thesis that there are necessarily true a posteriori identity propositions such as the one expressed in “Hesperus is identical with Phosphorus”, whereas the Direct Reference Theory—according to which the semantic function of certain expressions, e.g., proper names, is only to pick out an object (referent)—is able to deal with only their necessary truth. Thus, at least in so far as necessarily true a posteriori identity propositions are concerned, Fregeanism should be preferred to the Direct Reference Theory.     

Can Temperament Identify Affectively Ill Patients Who Engage in Lethal or Near‐Lethal Suicidal Behavior? A 14‐Year Prospective Study

Among affectively ill patients followed naturalistically for up to 14 years, 36 committed suicide, 120 attempted suicide, and 373 had no recorded suicide attempt. Comparing these three groups on clinical and intake personality revealed that suicide completed within 12 months was predicted by clinical but not personality variables, and suicide beyond 12 months was predicted by newly derived temperament factors, not clinical variables. Attempters and completers shared core characteristics: previous attempts, impulsivity, substance abuse, and psychic turmoil within a cycling/mixed bipolar disorder. Such temperament attributes as impulsivity and assertiveness were the best prospective predictors of completed suicides beyond 12 months with a sensitivity level of 74% and specificity level of 82%.     

生命伦理学:权力与不公正--在第六届国际生命伦理学大会的致辞

在现代生命伦理学的讨论中,主要关注的是改造医患关系中的权力关系。通过强调人权和对个人尊严的尊重,对脆弱人群授予权利已经达到。然而,在卫生保健中,权力的不平衡依然普遍存在。这在相当程度上与对社会不公正的关注不够有关。那种权力的不平衡加之新的权力形式的发展,例如,通过新的遗传生物技术,产生了对日益增长的社会不公的恐惧与忧虑。由此,扩展与公共卫生有关的伦理学讨论将受到关注。政治哲学研究也需要变为改造国际权力关系和改善人口健康。     

Cognitive estimations as a measure of executive dysfunction in childhood epilepsy

Children and adolescents with epilepsy are known to demonstrate executive function deficits. Despite prior work that has shown that cognitive estimation tasks are sensitive to executive dysfunction in children, such tasks have not been studied in children with epilepsy. This is particularly important given the fact that executive tasks have heretofore shown poor ecological validity, and it has been speculated that estimation tasks may show stronger ecological validity than other executive tests. One hundred and thirteen clinically referred children and adolescents with epilepsy were included. The Biber Cognitive Estimations Test was sensitive to cognitive dysfunction, with about half showing impairments on this task in comparison to age-matched normative data; the most frequently impaired subscales were quantity estimation and time estimation. Moreover, the Biber Cognitive Estimation Test showed moderate correlations with not only overall intellectual functions and academic achievement but also other commonly administered tests of executive functions, including digit span, Trailmaking, and the Tower of London but not with the contingency naming test. Cognitive estimations were also modestly correlated with age of epilepsy onset but not other epilepsy-severity variables such as number of antiepilepsy drugs (AEDs) or seizure frequency. Unfortunately, the hypothesis that the Biber Cognitive Estimation Test would show strong ecological validity was not supported, as it showed weak relations with parent-reported executive function deficits. The significance and limitations of this investigation are discussed.
