Analysis of a diverse cross‐sample of plant‐insect interactions suggests that the abundance of vitamin C (L‐ascorbic acid, ascorbate or AsA) in plants influences their susceptibility to insect feeding. These effects may be mediated by AsAs roles as an essential dietary nutrient, as an antioxidant in the insect midgut, or as a substrate for plant‐derived ascorbate oxidase, which can lead to generation of toxic reactive oxygen species. Ascorbate can also influence the efficacy of plant defenses such as myrosinases and tannins, and (...) alter insects' susceptibility to natural enemies. Conversely, herbivores appear to influence both de novo synthesis and redox cycling of AsA in their host plants, thereby potentially altering the nutritional value of crops and their susceptibility to pests. The recent development of genetically modified crops with enhanced AsA content provides both an impetus and a tool set for further studies on the role of AsA in plant‐insect interactions. (shrink)

Autorka kieruje swoją uwagę na estetyczne doświadczenie, sztukę oraz procesy estetyzacji w warunkach późnej nowoczesności. Estetyczne ukierunkowanie pracy nie oddala nas jednak od ważnych problemów współczesnej humanistyki. Łączy się bowiem z płaszczyzną filozoficznych pytań o kondycję człowieka zmagającego się z problemami skończoności istnienia, kontyngencji, braku pewności ontologicznej w dzisiejszym świecie. Wykłady prezentują trzy późnonowoczesne funkcje doświadczeń estetycznych, w tym sztuki. Iwona Lorenc sięga w swej prezentacji głównie do narzędzi fenomenologicznych, wskazując na przydatność fenomenologii do tego typu analiz. Jej odniesienia filozoficzne (...) są jednak znacznie szersze: nawiązuje do Kanta, do współczesnych sporów o aktualność niedokończonego projektu moderny w ujęciu Habermasa, przywołuje myśli Nietzschego, Husserla, Heideggera, Merleau-Ponty`ego, Vattima, Ricoeura, Adorna, Rancière`a, Lyotarda i wielu innych.

The book is a reflection over how art functions in late modernity. It emphasizes processes of fictionalizing reality and exposes, how phenomenology can be used to extract this problem on a foundation of aesthetics. It is a panoramic outlook over existing views, but also a self-sufficient theoretical proposal.

We investigate how a uniformly rotating frame is defined as the rest frame of an observer rotating with constant angular velocity Ω around the z axis of an inertial frame. Assuming this frame to be a Lorentz one, we second quantize a free massless scalar field in the rotating frame and obtain that creation-annihilation operators of the field are not the same as those of an inertial frame. This leads to a new vacuum state—a rotating vacuum. After this, introducing an (...) apparatus device coupled linearly with the field, we obtain that there is a strong correlation between the number of Trocheries-Takeno particles (in a given state) obtained via canonical quantization and the response function of the rotating detector. Finally, we analyze polarization effects in circular accelerators in the proper frame of the electron, making a connection with the inertial frame point of view. (shrink)

Este ensayo intenta poner en cuestión un problema central de la política democrática – la naturaleza del acto electoral – a la luz de la teoría sociológica de la acción, recorriendo el trayecto que separa al sentido subjetivo que el propio agente asigna a su acción en el momento de realizarla y las diversas descripciones “objetivas” que emergen a partir de las interpretaciones de la acción que realizan otros actores, en nuestro caso descripciones que se realizan en la esfera pública (...) y cuyos autores son un conjunto de individuos socialmente reconocidos como enunciadores legítimos de esas interpretaciones. Mi trabajo ofrece una reflexión sistemática sobre el modo en que se construye socialmente el significado de los comportamientos electorales. Partiendo de una serie de descripciones posibles de la acción de votar, intento mostrar las limitaciones de una teoría de la acción que reduzca el significado de ésta última al sentido que ella pueda tener para su autor o a la intención subjetiva que podemos imputarle. Así, se muestran las diversas interpretaciones de que puede ser objeto un “hecho” supuestamente básico y elemental, restituyendo el lugar de los discursos sociales en la producción del significado (objetivo) de una determinada acción individual.

Author: Lorenc Włodzimierz Title: HABERMAS’ PHILOSOPHY AS AN EXPRESSION OF FORGETTING ABOUT ONESELF AND COMMUNITY. CONSEQUENCES OF EXCESSIVE UNIVERSALITY OF PHILOSOPHY (Filozofia Jürgena Habermasa jako wyraz zapominania o sobie i wspólnocie. Konsekwencje nadmiernego uniwersalizowania filozofii) Source: Filo-Sofija year: 2006, vol:.6, number: 2006/1, pages:153-170 Keywords: HABERMAS, COMMUNITY, HUMAN EXISTENCE, UNDERSTANDING Discipline: PHILOSOPHY Language: POLISH Document type: ARTICLE Publication order reference (Primary author’s office address): E-mail:The task of the article is to show the consequences of the understanding of philosophy by Jürgen Habermas, (...) one of the most outstanding philosophers of our time. Some limitations in his philosophy appear in his utterances on the problems of man related to the possibilities offered by the recent achievements in genetics. As a philosopher he seems to be very distant from the reality of human existence. He proposes to cultivate a pure philosophy, striving first of all to ensure a universality for its solutions. This way he narrows the tasks confronting modern philosophy; besides, he wants to answer the questions concerning the humankind in a way valid for all times, making absolute the legal and constitutional frame being now in force.

Following Ricoeur and referring to some contemporary phenomenological studies I demonstrate—perhaps differently than others do—that Husserl’s phenomenological undertaking has also hermeneutic aspects. With Husserl, we are in a meaningful world which reveals its sense in intentional acts. The interpretation of senses can be treated as experiencing them. In particular, I examine the peculiar hermeneutics of affectiveness and sensation, i.e. the hermeneutics that is broadly understood as a project of demonstrating the origin of meaning. This project reaches the difference founding all (...) the articulations of meaning rather than some aprioric basis of understanding. The difference is a source that flows in experience of sense, even in their mature culturally articulatedforms, which are, however, forever permeated by sensation and the affective. (shrink)

Nadzieja radykalna to nadzieja obecna dotąd w dyskursie religijnym. Począwszy od Nietzschego tematyka ta zaczęła się również pojawiać w dyskursie filozoficznym. Punktem wyjścia artykułu jest myśl Ernesta Blocha, który uczynił z nadziei centralną kwestię rozważań filozoficznych, choć nie udało mu się rozwinięcie tej idei. W tym względzie pierwszeństwo przypada Nietzschemu, który dążył do złączenia filozofii z problematyką nadziei. Ostatnim filozofem, którego poglądy zostaną wzięte pod uwagę jest Quentin Meillassoux, dążący w ostatnich latach do filozoficznego podtrzymania nadziej dotąd kojarzącej się z (...) religią. Punktem docelowym rozważań, oprócz próby oceny propozycji każdego ze wspomnianych filozofów, jest sformułowanie wniosków odnoszących się do konsekwencji pojawienia się problematyki nadziei radykalnej na gruncie filozofii. Wskażę na sposób współczesnego filozofowania, który zdaje się otwierać szanse na powiązanie tej problematyki z filozofią. Can Philosophy substitute for religion? Philosophies of Radical Hope from Nietzsche to Meillassoux Radical hope is hope that could be found in religious discourse. Starting from Nietzsche, the concept entered also philosophical discourse. The article takes as its starting point the thought of Ernest Bloch, who placed hope at the center of philosophical thought, although, he was not able to develop the idea. In this respect, priority should be given to Nietzsche, whose views were taken up by Quentin Meillasoux, who has been aiming to philosophically uphold hope that has been usually associated with religion. The end point of the present deliberation, in addition to an attempt at evaluating the abovementioned philosophers’ propositions, is formulation conclusions concerning the consequences of the appearance of the problematics of radical hope in the field of philosophy. I will point to a way of contemporary practice of philosophy, which appears to open up opportunities to tie in this problematics with philosophy. (shrink)

The paper concerns a form of experiencing time which is specific for haiku poetry. Haiku is an expression of the momentary glimpse of time. Haiku poetry treats the moment uninstrumentally, neither as a result of the past nor as a transition to future deeds. Seen this way, the moment arises on the stream of time as a unique, existential experience. It is my attempt to explain the phenomenon of this experience of “now” as I explore the metaphors of “background”, “figure” (...) and “composition”. (shrink)

The aim of this article is to characterize hermeneutic philosophy in a manner that differs from the usual attempts at defining this philosophical direction, especially in German philosophy, that is by referencing traditional hermeneutics. I would like to propose expounding its characteristics not in a historical, but theoretical manner. This task involves analysing the place of hermeneutic philosophy among other tendencies in contemporary philosophy as well as showcasing the advantages of its way of philosophizing. The article does not discuss issues (...) related to this philosophy such as its limitations and unilaterality. (shrink)
