Aims and hypothesesIn an environment of absolute silence, researchers have found many of their participants to perceive phantom sounds. With this between-subject experiment, we aimed to elaborate on these research findings, and specifically investigated whether–in line with the fear-avoidance model of tinnitus perception and reactivity–fear or level of perceived threat influences the incidence and perceptual qualities of phantom sound percepts in an anechoic room. We investigated the potential role of individual differences in anxiety, negative affect, noise sensitivity and subclinical hearing (...) loss. We hypothesized that participants who experience a higher level of threat would direct their attention more to the auditory system, leading to the perception of tinnitus-like sounds, which would otherwise be subaudible, and that under conditions of increased threat, narrowing of attention would lead to perceptual distortions.MethodsIn total, N = 78 normal-hearing volunteers participated in this study. In general, the study sample consisted of young, mostly female, university students. Their hearing was evaluated using gold-standard pure tone audiometry and a speech-in-noise self-test, which is a sensitive screening test to identify subclinical hearing loss. Prior to a four-minute stay in an anechoic room, we randomized participants block design-wise in a threat and no-threat condition. Participants in the threat condition were deceived about their hearing and were led to believe that staying in the room would potentially harm their hearing temporarily. Participants were asked whether they perceived sounds during their stay in the room and rated the perceptual qualities of sound percepts. They were also asked to fill-out standardized questionnaires measuring anxiety, affect and noise sensitivity. The internal consistency of the questionnaires used was verified in our study sample and ranged between α = 0.61 and α = 0.90.ResultsIn line with incidence rates reported in the literature, 74% of our participants reported having heard tinnitus-like sounds in the anechoic room. Speech-in-noise identification ability was comparable for both groups of participants. The experimental manipulation of threat was proven to be effective, as indicated by significantly higher scores on a Threat Manipulation Checklist among participants in the threat condition as compared to those in the no-threat condition. Nevertheless, participants in the threat condition were as likely to report tinnitus percepts as participants in the no-threat condition, and tinnitus percepts were not rated as being louder or more unpleasant as a function of level of threat. For participants who did experience tinnitus percepts, a higher level of threat was associated with a higher degree of experienced unpleasantness. These associations were absent in those who did not experience tinnitus. Higher negative affect was only slightly associated with higher ratings of tinnitus unpleasantness.ConclusionWhereas our threat manipulation was successful in elevating the level of fear, it did not contribute to a higher percentage of participants perceiving tinnitus-like sounds in the threat condition. However, higher levels of perceived threat were related to a higher degree of perceived tinnitus unpleasantness. The findings of our study are drawn from a rather homogenous participant pool in terms of age, gender, and educational background, challenging conclusions that are applicable for the general population. Participants generally obtained normophoric scores on independent variables of interest: they were low anxious, low noise-sensitive, and there was little evidence for the presence of subclinical hearing loss. Possibly, there was insufficient variation in scores to find effects. (shrink)

In their environment, plants are continuously submitted to natural stimuli such as wind, rain, temperature changes, wounding, etc. These signals induce a cascade of events which lead to metabolic and morphogenetic responses. In this paper the different steps are described and discussed starting from the reception of the signal by a plant organ to the final morphogenetic response. In our laboratory two plants are studied: Bryonia dioica for which rubbing the internode results in reduced elongation and enhanced radial expansion and (...) Bidens pilosa for which the response occurs at distance, hence pricking the cotyledon of a plantlet induces the growth inhibition of both the hypocotyl and the axillary bud of the pricked cotyledon. Reception of the signal and transmission of the message. In Bryonia the signal is received by epidermal cells while in Bidens they are the cells adjacent to the midrib of the cotyledon which receive the mechanical signal. In both plants the message is transmitted via a wave of electric depolarization. This latter is composed of an action potential associated with a slow wave whose transmission rates are respectively 1cm s−1 and 1 mm s−1. Recent results have shown the involvement of Ca2+ in the triggering of the slow wave and the role of the H+ pump during the slow wave. Transient and fast biochemical responses. An entry of extraceilular Ca2+ into the cells and a transient increase in IP3 occur within seconds following the mechanical stimulus. At the same time, the membrane becomes more fluid, correlated with qualitative changes in phospholipids. The rapid increase in the concentration of peroxidated lipids may be correlated with ethylene biosynthesis which is stimulated after rubbing. Other parameters such as cytoplasmic pH, relative water content, hydric potential, membrane potential and modifications of K+, Mg2+-ATPase and Ca2+-ATPase activities, play a key role in the early responses induced by the traumatisms. Irreversible-biochemical responses. The mechanical stimulus performed on a Bryonia internode induces an acceleration of: i) enzymatic activities related to the lignification, ii) esterification of phenolic acids in the cell wall. Consequently the lignification process is accelerated. Storage of the information. After being received by the target cells the information can be stored during several days before being expressed. At the level of cotyledonary bud, the first message, previously stored, can be expressed or not by a second treatment. Bidens thus behaves as if it was able to “store” and to “retrieve” morphogenetic messages, using a sort of rudimentary memory. The nuclei of the bud cells of the pricked cotyledon show that these cells, initially in G2 phase, divide and then remain in the G1 phase. In Bryonia, calli derived from young stimulated internodes, keep thigmomorphogenetic characteristics during several weeks. In the last part of this paper the particularity of our plant model which permits a study of the transmission and storage of the message, is underlined. The links between the different steps induced by the stimulus are discussed. Special attention is devoted to second messengers and to the amplification of the message. (shrink)

Le concept de conflit revêt divers aspects. Entre les litiges, les violences, les différends, les désaccords, les guerres, il importe de définir les éléments de la conflictualité et le caractère institutionnel des recherches en matière de gestion et de résolution des conflits de nos jours. Néanmoins, nous sommes parvenus à percevoir que la clé du succès des résolutions des conflits pour une paix durable réside dans l’expérience humaine de la culpabilité et du pardon. Ce n’est certes pas des éléments nouveaux (...) pour les spécialistes et les diplomates en matière de gestion des conflits. Cependant, Ces deux notions sont reléguées au second plan au profit de compromis et de mesures coercitives à l’encontre des factions en conflits. Notre vision de la résolution des conflits est que sans la mise en exergue de l’expérience de la culpabilité et du pardon, les peuples vivront dans un conflit perpétuel qu’ils transmettront aux générations futures : la haine durable (sustainablehate). Est-il possible d’institutionnaliser le pardon et de mener des actions conduisant à une véritable culpabilité collective et individuelle préalable à toute réconciliation durable des peuples? La nature et la fréquence de nos conflits obligent à reconsidérer les méthodes d’approche jusqu’ici utilisées. En effet, c’est ce que tentent de faire certaines commissions pour la réconciliation appelée pour la plupart « Dialogue – Vérité – Réconciliation ; Dialogue – Justice – Réconciliation ; justice et paix, etc ». où les belligérants, les bourreaux et les victimes sont invités à l’aveu, à la vérité et au pardon pour un re-vivre ensemble. Mais dans l’espace d’un processus de réconciliation engagé à travers desdites commissions, les ballets de confessions aussi bien que les sentiments de victimisation se succèdent avant à l’arrière fond l’amnistie pour les bourreaux et l’octroi du pardon de la part des victimes. Cela, parait peu convainquant pour la raison que ces commissions sont en majeure partie installées par les vainqueurs du moment. Dans une certaine Afrique surtout, ces derniers (les vainqueurs) sont aidés par des alliés occidentaux de hauts niveaux. Il s’agit alors de processus où la paix est provisoire et se maintient au bout de la force ; et où les bourreaux sont toujours les autres. (shrink)

_Purpose__._ This article aims at outlining the socio-communicative prerequisites for the influence of personality on the acquisition of rigorous scientific knowledge. _Theoretical__ basis__._ The communicative foundations of an individual’s activity in general and the functioning of his consciousness in particular were laid by the philosophy of Edmund Husserl, primarily due to his introduction of the concepts of "intersubjectivity" and "lifeworld". From these positions, attempts were made to understand the discussion of Karl Popper and Thomas Kuhn regarding the role of the (...) individual in science, in particular, the concept of a "normal scientist" as a participant in the lifeworld of scientists who support special intersubjective norms of reproduction of this lifeworld through scientific communication. The concept of "communicative mind", correlated with the philosophy of Jürgen Habermas, best expresses the rational and argumentative principles of achieving consensus in science. _Originality__._ Social anthropology reveals the constitutive significance of teamwork in science as a way of achieving rigorous scientific knowledge. Social phenomenology concretizes this by emphasizing the need for constant improvement of the rules of this communication. The verification of scientific knowledge by facts is strictly determined by the observance of community-recognized scientific tools for achieving such verification, in particular, the conventional agreement within a certain community of scientists regarding the language of science, which is used to describe verification, falsification, and other procedures for organizing scientific knowledge into a system. _Conclusions._ Verification of the obtained scientific knowledge critically depends on the formulation, dissemination and observance of certain institutional rules of scientific communication. This applies, in particular, to the conventionally recognized rules for the verification of scientific knowledge by empirical facts: it is not an isolated scientist who should identify, verify, organize and evaluate empirical facts, but a community of scientists who conduct scientific research in an organized manner. Team scientific work is a special case of collective action, which is characterized by a high level of reflection and application of critical thinking on a communicative basis. In particular, the legitimation of acquired scientific knowledge occurs in the process of scientific research due to the observance of procedural rules and careful work with empirical facts.

The Inforare project aims to set up a system for the sharing of clinical and familial data, in order to study how genes are related to the severity of sickle cell disease. While the computerisation of clinical records represents a valuable research goal, an ethical framework is necessary to guarantee patients' protection and their rights in this developing field. Issues relating to patient information during the Inforare study were analysed by the steering committee. Several major concerns were discussed by the (...) committee and formalised in the patients' information letter: educating patients to aid the recruitment of family members, rules of confidentiality and the disclosure of aggregate, individual and unexpected research results. This paper presents the main issues addressed. (shrink)

_Purpose._ The paper is aimed at identifying the ways of scientist’s influence on the development of modern society as compared to those of intellectuals. _Theoretical basis._ The socio-anthropological approach to the role of scientists in post-industrial society shows the leading role of people of science as a social group in present-day society. However, philosophical axiology reveals that scientists in today’s society do not have the appropriate social status: neither in state governance nor in the sphere of forming public opinion. The (...) classical doctrine concerning intellectuals has suffered a crisis in recent decades, which is due to the growing gap between the group of intellectuals recognized by society and the sphere of science. A new theoretical approach to determining the role of present-day research scientists as intellectuals is necessary. _Originality._ Successful development of modern society in conditions of growing social turbulence necessitates the access of research scientists to the sphere of public communication. This is required both by the needs of science advancement itself – to receive its adequate funding and win wide public recognition, and by society’s needs – as it is scientists who can provide reliable diagnostics of social problems and formulate well-grounded programs for overcoming them. _Conclusions._ For overcoming social barriers and getting access to public space, scientists themselves have to recognize themselves as a destitute social group – those who are unfairly deprived of making principal decisions in today’s society. For that, scientists should become modern intellectuals. Unlike media intellectuals, scientists are to interact not with social masses but, first and foremost, with public elites. The scientist has to gain his/her independent status by achieving the recognition of his/her own ideas among social elites rather than by winning wide personal popularity. Hence, scientists must aim at obtaining the status of the elite for elites – this would reveal in scientists the deepest potential of a modern man. (shrink)

Polyclonal antibodies raised against the human erythrocyte nucleoside transporter were used to investigate the distribution of the nucleoside transporters in the placenta. Immunoblots of brush-border membranes isolated from the human syncytiotrophoblast revealed a cross-reactive species that co-migrated with the erythrocyte nucleoside transporter as a broad band of apparent M 55,000. In contrast, no labelling was detected in basal membranes containing a similar number of equilibrative nucleoside transporters as assessed by nitrobenzylthioinosine -binding. The absence of cross-reactive epitopes in basal membranes and (...) their presence in brush-border membranes was confirmed by confocal immunofluorescence microscopy. The results suggest that at least two isoforms of the NBMPR-sensitive nucleoside transporter are present in the human placenta. The lumenal surfaces of fetal capillaries, small placental vessels and umbilical vein ware also strongly labelled by the antibody, a finding that suggests that the high fetal-placental adenosine uptake previously reported is due to endothelial transporters.

A Comparative analysis of the philosophical systems of Upanishads Advaita Vedanta and the various schools of Buddhism in a comprehensive manner.

_Purpose._ This research involves revealing the methodological significance of the anthropological understanding of values for conducting modern scientific research. _Theoretical basis._ Philosophical anthropology acts as an epistemological basis for answers to ontological questions that are part of the structure of such problems in modern science as the construction of a scientific picture of the world, the ordering of data of natural attitude, and anthropocosmism. The ontological basis for the formation of the anthropological theory of values is the teaching of Wilhelm (...) Leibniz, Immanuel Kant, Rudolf Lotze, and Martin Heidegger. _Originality._ The creation of a scientific picture of the world, the research of natural attitude, and an anthropological approach to cosmology carried out from the viewing angle of the philosophy of values show the close mutual conditioning of these scientific issues. A successful determination of one’s value positions by a scientist-researcher is impossible without his/her agreeing with his/her picture of the world with the prevailing ideas about the world in their society. Such ideas are studied by anthropocosmism, which researches not so much the world in itself, but a view of this world from the standpoint of the existing state of society and the main intentions of its development. _Conclusions._ The value attitude of scientists at a certain stage of the development of scientific knowledge forms their picture of the world, which has the form of self-explanatory scientific provisions. The facts of modern physics must always, one way or another, receive their legitimation through the world of the human natural attitude. Even the unobservable characteristics of the microcosm are explained by appealing to knowledge about the observable characteristics of the world. The anthropocentric nature of cosmology is determined by the fact that in modern philosophy, the values of a person explain not only the way of one’s cognition but also the way of one’s inclusion in the world.

Electrical resistivity and ac-calorimetric measurements reveal a complex magnetic phase diagram for single crystals of the ferromagnetic Kondo-lattice compound CeAgSb2 at high pressures up to 80 kbar. The ferromagnetic order at TC = 9.6 K at ambient pressure is completely suppressed at a critical pressure PC = 35 kbar. Another magnetic transition, possibly antiferromagnetic, found above 27 kbar, attains a maximum value TN 6 K at 44 kbar and then appears to be completely suppressed by 50 kbar. Thermodynamic and transport (...) measurements in the ferromagnetic state indicate an energy gap Δ 30 K in the spin-wave excitation spectrum at ambient pressure which decreases to Δ 10 K at P = 30 kbar. No superconductivity is observed at ambient pressure above T 0.1 K, under applied pressure in the ferromagnetic state (P = 28.5 kbar), nor in the antiferromagnetic state (P = 33 − 46 kbar) above 0.3 K. © 2003 The American Physical Society.

If Spinoza is a thinker very present in the Faculties of Philosophy, on the other hand, he is presented as one of the great forgotten of the humanist programs of secondary education. Contrary to what happened with other philosophers, who had more chance of spreading in non-specialized contexts (we can cite Nietzsche, Pascal, Plato or Schopenhauer as obvious examples), Spinoza is generally considered a excessively systematic author, and complex, whose works would have been written for a small group of scholars. (...) Nothing could be further from the truth. Spinoza’s life was full of completely surprising events, from his estrangement from the Jewish community (which repudiated him in a strict and disagreeable way), through his dalliances with heterodox currents which gradually grew in power, until his meeting with Leibniz and his intrepid travels. from one part of his native Holland to another. In this article, we examine the concept of desire in Spinoza's philosophy and its connection to the philosopher's decision to find the greater good. Since the greatest good, in turn, is nothing but its own enjoyment, we conclude that ignoring its existence, seeking it, and living it are, respectively, the conditions of the vulgar, the philosopher, and the wise, as what happened in the Garden of Epicurus.

This mixed methods study examines how college students’ perceptions and experiences affect their understanding of academic integrity. Using qualitative and quantitative responses from the Personal and Social Responsibility Institutional Inventory, both quantitative and qualitative results demonstrate that while campuses may see a reduction in overall levels of cheating when punitive academic integrity policies are present, students may develop higher levels of personal and academic integrity through the use of more holistic and community-focused practices.

Cultural taboos and their sanctionshave helped to check abuse of the environmentat least among the local people. The disregardfor these traditional checks and balancesespecially among Christians has adverselyaffected their enforcement at this time. Theenvironment and culture preservation inAwka-South were investigated. The faithfulobservance of the traditional laws in the studyarea was attributed to the fact that Awka-Southarea had remained occupied by the same peoplefor centuries. The study showed that thepreserved forests and their shrines in Nibotown have largely remained intact. In Nisetown, (...) however, with nine shrines still inexistence, the rules have relaxed a little,mainly because they embraced modernization. Inthis town, the fringes of the forests may beused for farming but no felling of trees wouldbe allowed. The ``god'' of the shrine in Obunaguvillage was much revered until the advent ofChristianity. This religion has had an erodingeffect on the taboos, which were put in placeto protect their forests and streams. Theabandonment of traditional cultural practicesis doing harm that goes beyond the abrogationof traditional cultural practices to seriousthreat to natural environmental structures. Thecultures of the different tribes in Nigerianeed to be revisited for evaluation and studiesto enable their integration into modernpractices that will make the environment moresustainable. This will be more productive thanthe unilateral introduction of programs,execution, and maintenance methods that arecompletely new, or in many cases run contraryto the cultural practices of the local peopleand tribes of Nigeria.
