Peirce y lo incognoscible: Respuesta a Damiani
Kalpokas,Daniel;
T?3picos , 2011,
Abstract: this article replies to damiani's objections to a previous paper of mine about the incognizable in peirce: "the incognizable and the bounds of sense". i point out that our disagreements are mainly about two points: (1) whether it has any sense to assert that we cannot know if there are incognizables, and (2) whether peirce can defend his thesis ("the absolutely incognizable is absolutely inconceivable") without presupposing the idealism as a thesis about the nature of reality. i argue in favor of a positive answer for the first point, and a negative one for the second, and thus i try to justify an agnostic attitude with respect to the incognizable: we cannot know whether there are incognizables.
Pragmatismo, empirismo y representaciones: Una propuesta acerca del papel epistémico de la experiencia
Kalpokas,Daniel;
An??lisis filos?3fico , 2008,
Abstract: empiricism can be characterized, on the one hand, as a theory about the sources of empirical knowledge; on the other hand, as an epistemic outlook about justification of empirical beliefs. this last dimension of empiricism has been criticized by many philosophers nowadays. paradigmatically, rorty has said that experience is only the cause of beliefs, but not its justification. rorty's thesis is that beliefs relate to the world only causally. this paper has two parts. in the first it is argued, against rorty, that experience must be an epistemic instance of justification if beliefs are to have any objective content at all. in the second, it is proposed an alternative pragmatist conception of knowledge which i) attributes an epistemic role to experience without falling into "the myth of the given" and ii) reintroduces the concept of "representation" without compromising with representationalism.
Remembering Independence, Desiring Enemies: Reflections on Nationhood in Contemporary Lithuania
Ignas Kalpokas
Studies of Transition States and Societies , 2012,
Abstract: The paper addresses the remembrance of events surrounding the restoration of Lithuanian independence, as well as their repercussions on the present, concentrating on the younger generation that does not have first-hand experience of the period and, therefore, has to rely on other people’s accounts, textbooks, and other sources.If one considers the state and, especially, its social (or communal) dimension as impossible totalities, memory and history acquire significant importance as they both provide ‘a magma of significations’, out of which particular signifying structures are instituted in order to anchor meaning and exhort a unifying claim through dominant narratives that tend to subjugate the otherwise inevitable variety of discourses. The discourse of the Lithuanian history textbooks is analysed by outlining its emphasis on unity and self-sacrifice in 1988-1991, and by portraying the Lithuanian history as an unending struggle against enemies and their malevolent plots. Also, considering the accounts of young people, two tendencies are visible: first, a bias towards images of unity and self-sacrifice depicting the period concerned, second, the predilection to employ the categories of ‘aliens’ and ‘enemies’ is evident, significantly affecting perceptions of the present with widespread images of disintegration and decay in the absence of the Other.
Peirce y lo incognoscible: Respuesta a Damiani
Daniel Kalpokas
T?3picos , 2011,
Abstract: El presente artículo responde algunas objeciones que Damiani, en su trabajo "Comunidad, realidad y pragmatismo", efectúa a un artículo anterior mío sobre lo incognoscible en Peirce: "Lo incognoscible y los límites del sentido". Se alo que nuestros desacuerdos conciernen principalmente a dos puntos: (1) si tiene sentido sostener que no podemos saber si hay incognoscibles, y (2) si cabe defender la tesis de Peirce ("Lo absolutamente incognoscible es absolutamente inconcebible") sin comprometerse con el idealismo. Al argumentar por una respuesta afirmativa al primer punto y por una negativa al segundo, intento justificar una actitud agnóstica respecto de lo incognoscible: la de que no podemos saber si hay incognoscibles. This article replies to Damiani's objections to a previous paper of mine about the incognizable in Peirce: "The Incognizable and the Bounds of Sense".

On the value-distribution of the Riemann zeta-function on the critical line
Justas Kalpokas,J?rn Steuding
Mathematics , 2009,
Abstract: We investigate the intersections of the curve $\mathbb{R}\ni t\mapsto \zeta({1\over 2}+it)$ with the real axis. We show that if the Riemann hypothesis is true, the mean-value of those real values exists and is equal to 1. Moreover, we show unconditionally that the zeta-function takes arbitrarily large real values on the critical line.

Effect of a povidone-iodine intrauterine infusion on progesterone levels and endometrial steroid receptor expression in mares

Abstract: Fourteen healthy mares were used in this study. Estruses were synchronized and seven mares were treated with intrauterine infusions at days 0 and 2 post ovulation of two consecutive estrous cycles. Uterine biopsy samples were taken on days 6 and 15 post ovulation.The treatment did not induce an inflammatory response indicating endometritis, neither affected the ERα. However, it reduced the percentage of PR positive cells (PPC) on day 6 (deep glandular epithelium, control: 95.7 vs. infused: 61.5, P < 0.05). Treated mares tended to have lower progesterone levels on day 2 (3.9 ng/ml vs. 6.6 ng/ml, P = 0.07), and higher levels on day 15 compared with controls (4.4 ng/ml vs. 1.3 ng/ml, P = 0.07).a 1% povidone-iodine infusion during days 0 and 2 post ovulation in healthy mares did not induce histological changes indicating endometritis, but altered progesterone concentrations and reduced the expression of endometrial PR at day 6 without affecting the ERα. These changes could reduce embryo survival.Endometritis is a major cause of infertility in the mare [1] and factors such as perineal conformation and uterine clearance that depend on the breed, age and reproductive status contribute to the pathogenesis [2]. Rapid physical clearance of uterine contents after mating or foaling is most important in the uterine defence [2]. Therefore, intrauterine infusions have been used widely in the equine practice as a treatment to clear the uterus within 96 hours post ovulation [2-4]. The objective is that the embryo encounters a healthy endometrium around day 6, when it enters the uterus [5]. Povidone-iodine solutions are often used for intrauterine infusions due to their low cost, easy of preparation, storage and delivery and especially because they are indicated for the treatment of fungal infections [2,4]. However, contradictory findings have been reported on the consequences of using this antiseptic. A 0.05% povidone iodine solution infused into the uterus around the time of ovulat
