Following a hypnotic amnesia suggestion, highly hypnotically suggestible subjects may experience amnesia for events. Is there a failure to retrieve the material concerned from autobiographical memory, or is it retrieved but blocked from consciousness? Highly hypnotically suggestible subjects produced free-associates to a list of concrete nouns. They were then given an amnesia suggestion for that episode followed by another free association list, which included 15 critical words that had been previously presented. If episodic retrieval for the first trial had been (...) blocked, the responses on the second trial should still have been at least as fast as for the first trial. With semantic priming, they should be faster. In fact, they were on average half a second slower. This suggests that the material had been retrieved but blocked from consciousness. A goal-oriented information processing framework is outlined to interpret these and related data. (shrink)

Temporality is an under-researched area in entrepreneurship and business ethics, even though entrepreneurs are particularly affected by a fast-paced work environment. How do they position themselves in relation to the acceleration of time in order to construct meaning for their activity? We draw on fifty-four semi-structured interviews with entrepreneurs to outline the different ways in which they perceive a faster pace of work. We show how the meaning they give to their activity varies according to whether they accept or (...) resist the acceleration of time: (1) By claiming to accept a high work rate, entrepreneurs may see work as a way of keeping busy, having fun, forgetting, or achieving efficiency; (2) by asserting that they resist the acceleration of time, they view work as a way of setting ethical goals, doing their job better, experiencing unexpected encounters, or being creative. These two different perspectives on time and meaning are not incompatible: It is possible that achieving a harmonic balance between periods of acceleration and deceleration of time may foster the construction of meaningful entrepreneurship.

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)

How To Lose Weight and Change the World (1985), for example, deals with the issue of fat, tells you how to get it off and keep it off but, in very lean prose, it also probes deeply into the form of commitment. It contains chapters on fat, food, and roughage but others entitled “Running,” “Sex,” “How to live,” and “How to die.” Fat functions here as a metaphor—it is “what clutters the unexamined life” (p. 26)—representing “the nagging triviality, the utter banality, and the inevitability of ordinary reality that separate us from what we think we want to be” (p. 145).With an occasional nod to Sartre (We are what we eat as we are what we do.) and Pascal (By altering our behavior, we can alter our beliefs.), Watson writes to provoke his readers to make a commitment to get the fat out of their lives, to take control of their actions and, perhaps, by changing themselves, to change the world. If we can, for example, “control [our] own eating habits apart from the norm imposed by society” (p. 75), we can begin to act as individuals in all other matters and completely transform our lives and, possibly, those of others. Watson, who contributed a chapter to World Hunger and Moral Obligation (1977) and who, during the 1960s, wrote a still unpublished volume entitled Sex and Revolution in which he claims that if people could revolt sexually against the [End Page 420] taboos of America, they could then perhaps be convinced to take control of the world’s food production, now remarks here, as if in passing, that if we fast for a day or two to make up for binges, we will get “a gut comprehension of what hunger really is for as many as a third of the world’s people” (p. 129). At its deepest level, The Philosopher’s Diet unveils an entire world obsessed with food—“the rich are worried about eating too much and the poor too little” (p. 56)—and underscores the immorality of not trying to change a system of food production and distribution in which we are overfed while millions are starving.The Philosopher’s Joke (1990) is a tougher book to get a handle on. It contains five chapters written in the dominant styles of philosophical writing popular in each of the last five decades. Two additional chapters complete the volume: “How to Die” which appeared almost verbatim in The Philosopher’s Diet and “A Pig’s Tail (The End of the Second Millenium).” As the book’s cover warns us, it is not always easy to ascertain the author’s position vis-à-vis the opinions reached in the specific essays. The first two chapters, though, are clearly parodies of purely formalistic writing, while the third is a skeptical but straightforward and serious attempt to establish that all interpretation is subjective. The fourth deals with deception in Kierkegaard and the themes of innocence sullied and human entrapment in Western culture. The main joke here has been played on Kierkegaard by God, “the original con man” (p. 87). Chapter six examines recent novels and films that treat the relationships between humans and apes and asks, seriously, what it would mean regarding animal rights and the place of human beings in the cosmos, if it could be shown that apes and humans can interbreed.

Until quite recently, mind-body dualism has been regarded with deep suspicion by both philosophers and scientists. This has largely been due to the widespread identification of dualism in general with one particular version of it: the interactionist substance dualism of Réné Descartes. This traditional form of dualism has, ever since its first formulation in the seventeenth century, attracted numerous philosophical objections and is now almost universally rejected in scientific circles as empirically inadequate. During the last few years, however, renewed attention (...) has begun to be paid to the dualistic point of view, as a result of increasing discontent with the prevailing materialism and reductionism of contemporary scientific and philosophical thought. Awareness has grown that dualism need not be restricted to its traditional form and that other varieties of dualism are not subject to the difficulties commonly raised against Descartes' own version of it. -/- Interest in these alternative versions of dualism is growing fast today, because it seems that they are capable of capturing deep-seated philosophical intuitions, while also being fully consistent with the methodological assumptions and empirical findings of modern scientific work on the human mind and brain. The object of this book is to provide philosophers, scientists, their students, and the wider general public with an up-to-date overview of current developments in dualistic conceptions of the mind in contemporary philosophy and science.

Since 1992, Border Crossings has show cased Henry A. Giroux's extraordinary range as a thinker by bringing together a series of essays that refigure the relationship between post-modernism, feminism, cultural studies and critical pedagogy. With discussions of topics including the struggle over academic canon, the role of popular culture in the curriculum and the cultural war the New Right has waged on schools, Giroux identified the most pressing issues facing critical educators at the turn of the century. In this (...) revised edition, Giroux reflects on the limits and possibilities of border crossings in the 21st century. "Borders" in our post 9/11 world have not been collapsing, he argues, but vigorously rebuilt. In order to have a truly critically engaged citizenry the challenges of these new "borders"- such as the increased militarization of public spaces, the rise of neo-liberalism, and the war in Iraq- must play a vital role in any debate on school and pedagogy.

Giroux argues that challenge gives new meaning to the importance of resistance, the relevance of pedagogy, and the significance of political agency.

There exists a fundamental convergence between some major trends of modern epistemology—as outlined, for instance, by Filmer Northrop and Henry Margenau—and the theories actually developed within sciences of the human mind where two types of thought—one implicit and, the other, explicit—tend to refer to two different lines of development. Moreover, these theories can find in the psychology of Lev Vygotsky some seminal hypotheses of a major importance. In order to highlight this convergence, we parallel the role played by structured (...) conceptual systems in Vygotsky’s conception of intellectual development and Northrop’s epistemology. We show how these conceptual systems account for the notion of causality and can explain the success of scientific thought, i.e. its possible match with the real world, while this match falsely justified an overall biological model of intellectual development in Jean Piaget’s work. We conclude that dual process theorists should no longer neglect cognitive tools, and especially conceptual systems, which underpin the awareness and mastery of thought that are characteristic of type 2 processes. This whole analysis leads us to maintain that human psychology is not characterized in the first instance by a need to act, but a quest for meaning. (shrink)

With the election of Donald Trump to the presidency of the United States, the discourse of an authoritarianism and the echoes of a fascist past have moved from the margins to the center of American politics. A culture of war buttressed by the forces of white supremacy and militarization has been unleashed in a series of policies designed to return the United States to a history in which the public sphere was largely white and Christian, and the economy and the (...) state were governed by a ruling corporate elite. Militarization and a war culture have become normalized in the United States and this article explores the ways in which a neo-fascism has emerged that furthers war not only abroad but also at home, especially with regards to the ongoing assaults waged by the state against Muslims, immigrants, women’s reproductive rights, and poor minorities of class and color. Against the rise of neo--fascism, this article advances the idea that education is central to any viable notion of politics, that progressives... (shrink)

“… there is no distinction of meaning so fine as to consist in anything but a possible difference of practice.”“… Consider what effects, that might conceivably have practical bearings, we conceive the object of our conception to have. Then, our conception of these effects is the whole of our conception of the object.”One example which Peirce chose to illustrate his pragmatic maxim as thus stated was the familiar theological distinction between transubstantiation and consubstantiation. Now since these two doctrines agree in (...) all of the effects which they conceive the sacrament to possess and which may have practical bearings, here and hereafter, it is absurd to say that there is any real distinction between the two doctrines. Peirce declares in the same passage that, having used the question as a logical example only, he does not care to pause to anticipate the theologian's reply. (shrink)

RésuméAprès avoir déflni la Psychologie comme la science des personnaliés, de leurs activité au sein des situations qui les confrontent, et de leur développement dans un milieu physique, social et culturel donné, le Dr Murray formule un certain nombre de propositions et conceptions théo‐riques destinées à rendre compte des faits psychiques. Les unes sont ?ordre général, les autres concernent la motivation. Propositions générales. 1. La personnalitéà son siège dans le cerveau.2. Elle dure et se développe dans le temps par suite (...) des opérations qu'elle est amenée à produire.3. Ces opérations sont internes ou externes, et correspondent à des attitudes ?introversion ou ?extroversion. Toutes comportent une dimension temporelle, un début, un déroulement de longueur variable, une fin.4. Les opérations externes sont constituteées ?une série de champs momentanés , le champ lui‐même résultant de la combinaison ?une situation externe et ?un état interne. II importe de distinguer de la situation réelle, la situation telle que la voit le sujet. Cette distinction revêt une importance particulière dans le cas des relations sociales.5. Ľobjet ?étude du Psychologue consiste alors, non pas dans le comportement du seul sujet, mais dans ľinteraction du sujet et de ľobjet. Celle‐ci, avec ses deux aspects complémentaires de besoin et de pression est ce que le Dr Murray à appeié ailleurs un théme.6. Les actions Psychologiques s'ordonnént fréquemment en séquences tendant àľobtention ?un but éioigné. Les démarches intermédiates s'expliquent alors, non pas par ľinfluence des facteurs externes contemporains, mais par celle des facteurs internes antérieurs. Ce sont, non des réactions, mais des proactions. Elles ne sont pas homéostatiques et subor‐données à la restitution ?un équilibre antérieur, mais _HYPERLINK “superstatiqu.es” et visant à la production de quelque chose de neuf. Séquences et proactions composent pour une grande part ľego‐system.7. Ľévolution de la personnalité s'ordonné en périodes relativement longues dont il est possible de prendre au cours de brefs laps de temps une sorte ?échantillonnage.8. La personnalité fait montre ?une intégration variable, perceptible aux niveaux des opérations, des séquences ou des périodes.9. Elle se transforme sans cesse par ľeffet des opérations ou elle est engageée, ces transformations graduelles et insensibles pouvant s'accumuler jusquà déclencher à un moment donné des revirements spectaculaires tels que les conversions.10. Le donné du Psychologue est de deux sortes: faits subjectifs communiqués par le sujet, faits objectifs recueillis par ľobservateur extérieur. II importe ensuite ?expliquer ce donné, autrement dit de construire une représentation hypothétique du psychisme du sujet, qui permette de comprendre ses conduites passées et de prédire ses conduites futures. Ces constructions n'ont pas encore atteint le stade ?une tľpologie satisfaisante. Concepts relatifs à la motivation. Dans la représentation théorique dont il vient ?être parlé, une place éminente revient aux concepts relatifs à la motivation: tendance, instinct, besoin, vecteur psychique concu à la façon de Lewin. La Psychologie américaine à pendant longtemps tendu à restreindre le nombre de ces besoins, et à n'admettre comme tout à fait fondamentaux et originels que ceux qui concernent la nourriture et le sexe. II est impossible de comprendre les actions humaines si ľon ne réserve une place à des tendances, activités et satisfactions ?un ordre plus élevé. Notamment:1. Ľêtre vivant peut dépenser le surplus ?énergie dont il dispose dans des actions spontanées, non déclenchées par un stimulus externe. Ľaction trouve alors sa gratification en elle‐même et non dans le résultat qu'elle procure .2. Un plaisir supplémentaire peut résulter de la manière plus ou moins harmonieuse dont se déroule ľaction, indépendamment de ľeffet où elle arrive.3‐4. Il existe des besoins ?ordre mental oùľesprit cherche sa satisfaction propre et non celle de ľorganisme. On voit alors ľimagination ľemporter sur la perception et le donné s'analyser et se recomposer en créations originales. Ces besoins et les actes qu'ils provoquent procurent les trois sortes de plaisirs distingués plus haut. Leur but n'est pas préala‐blement donné, mais doit être construit pièce par pièce.5‐6. à côté des besoins positifs existent des besoins négatifs qui poussent àéviter, exclure, ou détruire. De même, aux besoins réactifs s'opposent les besoins proactifs, spontanés et créateurs. Les premiers peuvent devenir proréactifs par ľintervention de ľanticipation, les seconds réproactifs sous ľeffet de circonstances inattendues. Ces diverses sortes de conduites peuvent servir à classer les individus ?après la place considérable ou réduite qu'elles occupent dans son comportement.7. Les besoins se spécifient par canalisation ou cathection . Ils peuvent aussi par généralisation sétendre à de nouveaux objets. Ľexcès ou le manque absolu de fixation sont des symptômes ?immaturityé. – Une importance particulière revient, dans le cadre de cette théorie, à la notion freudienne de cathexis. Certains objets et buts sont adoptés à la faveur de circonstances où joue le trial and error. Dautres, purement idéaux àľorigine, sont recherchds par ľindividu sans jamais avoir été rencontrés par lui. Si le trial and error intervient ici, c'est sur le plan de ľimagination. – La Psychologie américaine à restreint en général la notion et le terme ?apprentissage àľacquisition des moyens de satisfaction àľexclusion des fins. De même, la civilisation contemporaine, si elle à prodigieusement développé’ les techniques, à perdu la notion ?un commun idéal humaniste. II importerait de revenir, ?un point de vue théorique non moins que pratique, àľapprentissage des fins, autrement dit au processus par lequel ľindividu, sous la poussée de besoins largement indifférenciés adopte tel nouveau but, s'attache à telle valeur, jugée par lui source de satisfaction.8. Les besoins peuvent être conscients ou inconscients. Dans le dernier cas, ľindividu les refoule sous la pression des impératifs sociaux. Ils se mafestent alors de diverses façons détournées, éventuellement névrotiques, et peuvent se retourner contre le sujet.9‐10. II existe un ordre ?urgence dans la satisfaction des besoins, les plus biologiques réclamant le plus impérieusement satisfaction, les plus Aleves et altruistes ne se faisant sentir qu'ensuite.11. La Psychologic sociale récente à artificiellement dissoci^ les notions ?inUret, attitude et valeur de celle de besoin. Mais la notion de besoin à son tour demande une analľse plus poussee. Le besoin comprend deux composantes : Ľaction à quoi il pousse ou vedeur proprement dit, la valeur ou entite valorisee au benefice de laquelle s'effectue cette action. Toute conduite concrete apparait alors comme un systéme valeur‐uecteur et peut être analľsee de ce double point de vue. (shrink)
