Intrauterine insemination is one of many treatments provided to infertility patients. Many factors such as, but not limited to, quality of semen, the age of a woman, and reproductive hormone levels contribute to infertility. Therefore, the aim of our study is to establish a statistical probability concerning the prediction of which groups of patients have a very good or poor prognosis for pregnancy after IUI insemination. For that purpose, we compare the results of two analyses: Cluster Analysis and Kohonen Neural (...) Networks. The k-means algorithm from the clustering methods was the best to use for selecting patients with a good prognosis but the Kohonen Neural Networks was better for selecting groups of patients with the lowest chances for pregnancy.

The aim of this paper is to present the method of Socratic proofs for seven modal propositional logics: K5, S4.2, S4.3, S4M, S4F, S4R and G. This work is an extension of [10] where the method was presented for the most common modal propositional logics: K, D, T, KB, K4, S4 and S5.

My aim in this paper is to re-examine specialization in science. I argue that we need to acknowledge the role that conceptual changes can play in the creation of new specialties. Whereas earlier sociological accounts focus on social and instrumental changes as the cause of the creation of new specialties, I argue that conceptual changes play an important role in the creation of some scientific specialties. Specifically, I argue that conceptual developments played an important role in the creation of both (...) endocrinology and virology. (shrink)

Context: Metaphysics of perception explores fundamental questions regarding the structure and status of the perceived world or appearance(s. By virtue of perception, the apparent world comes to existence. This, however, does not mean that the apparent world is a projection of mind, that it exists “in the head.” Implications: PL-metaphysics reconciles realism with constructivism. As such, it might be considered either an alternative to constructivism or an improvement and completion of this position. Constructivist content: The article refers to non-Cartesian movements (...) in contemporary philosophy, including radical constructivism, enactive and embodied cognition. Keywords: Perception, metaphysics, radical constructivism, realism, appearance, Jerzy Perzanowski, Plato, Gottfried Willhelm Leibniz, Ernst von Glasersfeld. (shrink)

Open peer commentary on the article “The Banathy Conversation Methodology” by Gordon Dyer, Jed Jones, Gordon Rowland & Silvia Zweifel. Upshot: I compare two closely related methodologies: the Banathy Conversation Methodology and Structured Dialogic Design (or Structured Democratic Dialogue, SDD.

A partir de son apparemment étrange observation d'une influence cachée des étoiles sur l'action humaine une attentive reconsidération du concept de l'actus humanus de Saint Thomas dans la Prima Secundae révèle une vue plus ample des processus internes à l'agent humain qui contribuent à la spécification individuelle de l'action humaine et, donc, de la liberté humaine. Il semble que parmi les adeptes de la théorie thomiste de l'action, l'influence importante que l'appétit sensible peut exercer en cette direction, tout en restant (...) entièrement caché aux actes conscients de l'intellect et de la volonté de la personne, n'a pas été reconnue jusqu'aujourd'hui. Dans sa théorie de l'action Saint Thomas fournit un cadre solide pour une réflexion ultérieure sur l'influence de l'inconscient dynamique sur la liberté et pour une intégration critique interdisciplinaire des intuitions valides de la psychologie des profondeurs. En plus, il semble que la redécouverte de son concept plus large de l'actus humunus rende possible de repenser à profit certains éléments classique de son éthique. (shrink)

Aristotle claims man is a political animal and that the polis exists by nature. Taking literally his analogy between the legislator and the craftsman, Aristotle's critics contend that he 'blunders' because the polis is artificial, devised by a legislator/founder and imposed on a people. We defend Aristotle's claims by showing, first, how Aristotle's claim that man is by nature an animal possessing logos -- speech/reason -- grounds his account of the natural development of the polis out of the earliest partnerships (...) (which the critics concede are natural); second, that the person who first brought people together in a polis may well have done so without realizing the scope of his actions; and, finally, that the developmental process is clearly one of praxis (action), not poisis (making, the imposition of a form on matter). Aristotle's claims are evidenced by the Homeric hero Philoctetes, whom one critic takes to disprove Aristotle's theses. (shrink)

Kuhn argues that science does not aim at the truth. Alexander Bird raises concerns form Kuhn's view. I defend Kuhn's claim and argue that insofar as science has a goal it is a moving target.
