Listening to someone from some distance in a crowded room you may experience the following phenomenon: when looking at them speak, you may both hear and see where the source of the sounds is; but when your eyes are turned elsewhere, you may no longer be able to detect exactly where the voice must be coming from. With your eyes again fixed on the speaker, and the movement of her lips a clear sense of the source of the sound will (...) return. This ‘ventriloquist’ effect reflects the ways in which visual cognition can dominate auditory perception. And this phenomenological observation is one what you can verify or disconfirm in your own case just by the slightest reflection on what it is like for you to listen to someone with or without visual contact with them.

İslam felsefesinin tartışmasız en önemli filozoflarından biri olan İbn Sina, dönemindeki yoğun Aristoteles etkisine karşılık, Aristoteles’in sisteminden bağımsız yeni bir zaman sistemi kurmuştur. Şifa isimli kitabında bu sistemi sunan İbn Sina, aynı zamanda hareket, hız, mekansal büyüklük gibi belli kavramların yanında bölünebilir bir büyüklük olan ve zorunlu bir şekilde öncelik ve sonralığa sahip olan bir kapasite olarak tanımladığı imkana dayalı bir zamanın gerçekliği savunusu yapmakla birlikte bu kavramların anlam kazanabilmesi için zaman kavramına ihtiyacımız olduğunu göstermiştir.Zamanın gerçekliği sorusu, güncel (...) felsefenin aktörlerinden de büyük dikkat çekmiştir. Bu isimlerden biri olan J. Ellis McTaggart, hayli tartışmalı olmasının yanısıra etkili de olan “Zamanın Gerçekdışılığı” başlıklı makalesinde zamanın bir illüzyondan ibaret olduğunu tartışmıştır. McTaggart, gerek bu makalede gerekse Varoluşun Doğası isimli kitabında zamanın gerçek olmadığını ve zamana dair verdiğimiz her tanımın döngüsel, çelişkili veya yetersiz olduğunu savunmuştur. McTaggart, bu ispatını zamandaki anların birbirine nispetle iki farklı şekilde sınıflandırılabileceği varsayımı üzerine kurgulamıştır. Buna göre A serisi, zamandaki anları geçmiş, şu an ve gelecek şeklinde konumlandırırken B serisi, öncelik ve sonralık ilişkisi ile konumlandırmaktadır. Bu çalışma, İbn Sina’nın sunduğu zaman sisteminin McTaggart’ın B serisi ile uyumlu olup olmadığı sorusunu cevaplamayı amaçlamaktadır.Anahtar kelimeler: İbn Sina, Zaman, Mekansal Büyüklük, İmkan, Hareket, McTaggart, B serisi.

Trust among current and future patients is essential for the success of biobank research. The submission of an informed consent is an act of trust by a patient or a research subject, but a strict application of the rule of informed consent may not be sensitive to the multiplicity of patient interests at stake, and could thus be detrimental to trust. According to a recently proposed law on “genetic integrity” in Sweden, third parties will be prohibited from requesting or seeking (...) genetic information about an individual. Cumbersome restrictions on research may be lifted, thus creating a more favourable climate for medical research. (shrink)

Next SectionFollowing the influential Gifford and Reith lectures by Onora O’Neill, this paper explores further the paradigm of individual autonomy which has been so dominant in bioethics until recently and concurs that it is an aberrant application and that conceptions of individual autonomy cannot provide a sufficient and convincing starting point for ethics within medical practice. We suggest that revision of the operational definition of patient autonomy is required for the twenty first century. We follow O’Neill in recommending a principled (...) version of patient autonomy, which for us involves the provision of sufficient and understandable information and space for patients, who have the capacity to make a settled choice about medical interventions on themselves, to do so responsibly in a manner considerate to others. We test it against the patient–doctor relationship in which each fully respects the autonomy of the other based on an unspoken covenant and bilateral trust between the doctor and patient. Indeed we consider that the dominance of the individual autonomy paradigm harmed that relationship. Although it seems to eliminate any residue of medical paternalism we suggest that it has tended to replace it with an equally (or possibly even more) unacceptable bioethical paternalism. In addition it may, for example, lead some doctors to consider mistakenly that unthinking acquiescence to a requested intervention against their clinical judgement is honouring “patient autonomy” when it is, in fact, abrogation of their duty as doctors.

The connection between similarity logic and the theory of closure operators is examined. Indeed one proves that the consequence relation defined in [14] can be obtained by composing two closure operators and that the resulting operator is still a closure operator. Also, we extend any similarity into a similarity which is compatible with the logical equivalence, and we prove that this gives the same consequence relation.

IntroductionBisphenol A is highly debated and studied in relation to a variety of health outcomes. This large variation in the literature makes BPA a topic that is prone to selective use of literature, in order to underpin one’s own findings and opinion. Over time, selective use of literature, by means of citations, can lead to a skewed knowledge development and a biased scientific consensus. In this study, we assess which factors drive citation and whether this results in the overrepresentation of (...) harmful health effects of BPA.MethodsA citation network analysis was performed to test various determinants of citation. A systematic search identified all relevant publications on the human health effect of BPA. Data were extracted on potential determinants of selective citation, such as study outcome, study design, sample size, journal impact factor, authority of the author, self-citation, and funding source. We applied random effect logistic regression to assess whether these determinants influence the likelihood of citation.ResultsOne hundred sixty-nine publications on BPA were identified, with 12,432 potential citation pathways of which 808 citations occurred. The network consisted of 63 cross-sectional studies, 34 cohort studies, 29 case-control studies, 35 narrative reviews, and 8 systematic reviews. Positive studies have a 1.5 times greater chance of being cited compared to negative studies. Additionally, the authority of the author and self-citation are consistently found to be positively associated with the likelihood of being cited. Overall, the network seems to be highly influenced by two highly cited publications, whereas 60 out of 169 publications received no citations.ConclusionIn the literature on BPA, citation is mostly driven by positive study outcome and author-related factors, such as high authority within the network. Interpreting the impact of these factors and the big influence of a few highly cited publications, it can be questioned to which extent the knowledge development in human literature on BPA is actually evidence-based.
