Objective: Persuasive messages regarding fruit and vegetable consumption often meet defensive reactions from recipients, which may lower message effectiveness. Individual differences in emotion regulation and gender are expected to predict these reactions. In the working memory account of persuasion, inducing voluntary eye movements during the processing of the auditory persuasive information might prevent defensiveness and thereby increase message effectiveness.Methods: Participants in two independently recruited samples from the general population listened to a negatively framed auditory persuasive message advocating fruit (...) and vegetable consumption. Half of them were asked to keep following a regularly moving stimulus on their screen with their eyes. At pretest, the individual differences of cognitive self-affirmation inclination and gender were assessed to predict defensive reactions.Results: In Study 1, induced eye movements significantly increased self-reported consumption after 2 weeks when CSAI was low, but only in males, as indicated by a significant three-way interaction. With negative self-evaluative emotions as dependent variable, this three-way interaction was also significant, suggesting that induced eye movements prevented defensiveness in low CSAI males. Study 2 did not assess consumption but replicated the latter three-way interaction.Conclusion: The studies replicated our earlier findings regarding the moderating effects of individual differences in emotion regulation on persuasion, but they also revealed gender differences in persuasion that are related to the working memory. The working memory account of persuasion provides new theoretical as well as practical angles on persuasion to target individuals in persuasion to increase fruit and vegetable consumption. (shrink)

Many studies have argued for distinct but complementary contributions from each hemisphere in the control of movements to visual targets. Investigators have attempted to extend observations from patients with unilateral left- and right-hemisphere damage, to those using neurologically-intact participants, by assuming that each hand has privileged access to the contralateral hemisphere. Previous attempts to illustrate right hemispheric contributions to the control of aiming have focussed on increasing the spatial demands of an aiming task, to attenuate the typical right hand advantages, (...) to try to enhance a left hand reaction time advantage in right-handed participants. These early attempts have not been successful. The present study circumnavigates some of the theoretical and methodological difficulties of some of the earlier experiments, by using three different tasks linked directly to specialized functions of the right hemisphere: bisecting, the gap effect, and visuospatial localization. None of these tasks were effective in reducing the magnitude of left hand reaction time advantages in right handers. Results are discussed in terms of alternatives to right hemispheric functional explanations of the effect, the one-dimensional nature of our target arrays, power and precision given the size of the left hand RT effect, and the utility of examining the proportions of participants who show these effects, rather than exclusive reliance on measures of central tendency and their associated null hypothesis significance tests.

Fossil fuel divestment movements have gained momentum since 2011, aimed at ending fossil fuel use and a move toward a cleaner, affordable, and sustainable energy system, for business and society. The present study investigates the direct impact of fossil fuel divestment announcements on stock prices of firms listed on the United States' stock exchanges. Using an event study and guided by the United Nation's sustainable development goals (SDGs), we test the effects of 116 divestments announcements between 2014 and 2019 on (...) 51 publicly traded fossil fuel companies. Our results suggest that there is a negative effect of these announcements on fossil fuel firm stock prices. Also, we find that the type of fossil fuel firm (coal or oil and gas), the type of divestment (partial, coal only, or full), the timing of the announcement, and the size of the divesting investor have some explanatory power in relation to the (cumulative) abnormal returns following the divestment announcements. While the negative impact on stock prices is not surprising, the reaction from the divested firms after such large divestitures is not consistent with what may be expected, given past reactions to divestitures seeking to achieve different social goals. Given the SDGs, it seems clear why investors are divesting themselves from fossil fuel firms, but why has the reaction to the 116 divestments led to very little change in the way these publicly traded fossil fuel firms do business given their direct and growing impacts on society? We conclude the study with some suggestions for future research. (shrink)

This article offers an interpretation of lawyers’ reactions to verse judgments, being judicial decisions rendered in rhymed poetry form. While, in recent history, there has been an unexplained break in the close historical connection between poetry and law, some judges nevertheless continue to render their judicial decisions in verse. This has met strong criticism from fellow judges, inevitably, but also from lawyers. However, there is no evidence in academic writing of anyone attempting to explain why lawyers are having these (...) reactions. Endeavouring to fill that void, this research employs hermeneutics to offer an interpretation of lawyers’ reactions to verse judgments. The article analyses the varied opinions uncovered in five qualitative interviews with lawyers of different backgrounds, and contends that a movement of poetry back towards its utilitarian origins would see lawyers change their reaction to verse judgments, instead viewing them as an appropriate form of judicial expression.

We posit a key goal of firms’ corporate social responsibility efforts is to influence reputation through carefully crafted communicative practices. This trend has accelerated with the rise of social media such as Twitter and Facebook, which are essentially public message networks that organizations are leveraging to engage with concerned audiences. Given the large number of messages sent on these sites, only some will be effective and achieve broad public resonance. Building on signaling theory, this paper asks whether and how messages (...) conveying CSR-related topics resonate with the public and, if so, which CSR topics and signal qualities are most effective. We test our hypotheses using data on public reactions to Fortune 500 companies’ CSR-focused Twitter feeds, using the retweeting of firms’ messages as a proxy for public resonance. We find resonance is positively associated with messages that convey CSR topics such as the environment or education, those that make the topic explicit through use of hashtags, and those that tap into existing social movement discussions.

We investigate in detail the electromagnetic fields of a uniformly accelerated charge, in order to ascertain whether such a charge does ‘emit’ radiation, especially in view of the Poynting flow computed at large distances and taken as an evidence of radiation emitted by the charge. In this context, certain important aspects of the fields need to be taken into account. First and foremost is the fact that in the case of a uniformly accelerated charge, one cannot ignore the velocity fields. (...) This then leads to other equally vital points. The net field energy turns out to be exactly the same as that of a non-accelerated charge having a uniform velocity equal to the instantaneous velocity of the uniformly accelerated charge. Further, the Poynting vector, seen with respect to the ’present’ location of the uniformly accelerated charge, during the deceleration phase, possesses everywhere a radial component pointing inward toward the charge, becoming nil when the charge becomes momentarily stationary, and during the acceleration phase, points away from the charge position. Last, but not least, when the leading spherical front of the relativistically beamed Poynting flux, advances forward at a large time t to a far-off distance \, the charge too is not lagging far behind. In fact, these relativistically beamed fields, increasingly resemble fields of a charge moving in an inertial frame with a uniform velocity \, with a convective flow of fields in that frame along with the movement of the charge. There is no other Poynting flow in the far-zones that could be termed as radiation emitted by the charge which, in turn, is fully consistent with the absence of radiation reaction and is also fully conversant with the strong principle of equivalence.

ArgumentIn this essay, I sketch a problem-based framework within which I locate the concept of “organism” in the system theories of Georg Ernst Stahl, Théophile Bordeu, and Paul-Joseph Barthez. Around 1700, Stahl coins the word “organism” for a certain concept of order. For him, the concept explains the form of order of living bodies that is categorically different from the order of other bodies or composites. At the end of the century, the “organism” as a specific form of order becomes (...) a major topos in many discourses. I will not so much focus on experiments and objects as on basic problems that contribute to the general framework of the concept of organism as a key concept of the vitalist movement between 1700 and 1800. For this purpose, I will investigate the combination of three explanatory tools. These tools refer to regulating agents, functional interactions, and stimulus-reactions-schemes within individual organic systems of forces. They are related to various themes – especially to energy, sensibility, and sympathy. I will retrace some aspects of these relations. (shrink)

We don't understand the reactionary mind. As a result, argues Mark Lilla in this timely book, the ideas and passions that shape today's political dramas are unintelligible to us. The reactionary is anything but a conservative. He is as radical and modern a figure as the revolutionary, someone shipwrecked inthe rapidly changing present, and suffering from nostalgia for an idealized past and an apocalyptic fear that history is rushing toward catastrophe. And like the revolutionary his political engagements are motived by (...) highly developed ideas. Lilla unveils the structure of reactionary thinking, beginning with three twentieth-century philosophers--Franz Rosenzweig, Eric Voegelin, and Leo Strauss --who attributed the problems of modern society to a break in the history of ideas and promoted a return to earlier modes of thought. He then examines the enduring power of grand historical narratives of betrayal to shape political outlooks ever since the French Revolution. These narratives are employed to serve different, and sometimes expressly opposed, ends. They appear in the writings of Europe's right-wing cultural pessimists and Maoist neocommunists, American theoconservatives fantasizing about the harmony of medieval Catholic society and radical Islamists seeking to restore a vanished Muslim caliphate. The revolutionary spirit that inspired political movements across the world for two centuries may have died out. But the spirit of reaction that rose to meet it has survived and is proving just as formidable a historical force. We live in an age when thetragicomic nostalgia of Don Quixote for a lost golden age has been transformed into a potent and sometimes deadly weapon. Mark Lilla helps us to understand why. (shrink)

This article explores the role of the Afrikaans sister churches during the initial stages of the fight against communism. After initially sketching the relations between South Africa and Russia until the Bolshevik Revolution of 1917, focus is placed on a narrow case of financial support from the side of the Reformed Church in South Africa via the Reformed Churches in the Netherlands towards the reformed movement in Polish-Ukraine during the 1930s and 1940s. Through the use of primary sources, this (...) small historical cross-section illustrates how the GKSA, in cooperation with the other Afrikaans churches, fought the battle against communism during these initial stages. It also highlights the motivations that drove them. The sources reveal that the GKSA was not only concerned about the Reformed movement in far-away Polish-Ukraine, but that there was also a healthy measure of self-preservation and self-interest involved, protecting South Africa and its Christian population from the influence of communism by subtly promoting Calvinism as a formative paradigm for Afrikaner nationalism.Contribution: This article contributes to a better understanding of the relations between Reformed Churches in South Africa and Eastern Europe during the first half of the 20th century, as well as to the role of the churches in fighting what it perceived as dangerous ideological influences.

Appeal to standard set theory in minimalist syntax is shown to be in conflict with the goal of analyzing dependency formation, a.k.a. movement, as involving genuine constituent copies. The underlying tension is due to extensionality, which—other things being equal—favors a perspective on dependencies in terms of multidominance. The above argument is developed against the backdrop of a recent exposition of minimalist syntax :229–261, 2019), which can be seen as exemplary. The resulting critical assessment should be taken as removing obstacles (...) on the way toward proper minimalist foundations for syntactic theory. (shrink)

There are three sentimental centres of 20th-century philosophical geography: Todtnauberg, Frankfurt and Vienna. Their exceptional status results not only from having given rise to decisive philosophical movements but also from the weight of stories about victimization and exile lacking with regard to Paris, Berkeley and Cambridge. Each of these centres is compromised in its own way: the Schwarzwald cottage from which Heidegger emerged to take over the Rektorat of Freiburg University and to which he returned after this disastrous intermezzo, the (...) "Institut für Sozialforschung" which on its part returned to claim moral authority at a location that increasingly turned into the most important bridgehead of transatlantic logistics, finally the former imperial city where traces of the origins of analytic philosophy were only conserved beneath the enormous sedimentation of a massive counter-reformation. Provincialism, NATO and tourism turned out to be perfectly compatible with remembrance of an heroic epoch at these sites while exiting philosophical work was being done at different locations. How much weight is carried by impressions like these? Not too much as long as well defined philosophical schools promote progress as defined within their own realm. Some doctrin, established all over the world does not depend on the place at which it is further refined. It is, however, in doubt whether philosophy counts among the disciplines so easily internationalized; Heidegger and Adorno being among those who would insist on the inseparability of a theory's fate and its place of origin. Be this as it may, my subject being the precarious relationship between the city and the Circle of Vienna I have to start from the assumption of obvious incomparability between the roots and the extension of the branches of the movement. Only a decade ago this would have presented itself as a fairly easy task. Historians were coming to this city to save the remnants of the beginnings of the movement whereas Anglo-American philosophers were busy refining the orthodoxy and hardly interested in historical matters. Much has changed since. Firstly the analytic enterprise is in certain ways approaching what can be called closure from within.gif Secondly Austrian universities have (with sometimes considerable delay) taken an interest in what is felt to be a lost opportunity.gif Both of these developments coincided with a more general renaissance of fin de siecle and modernist Vienna. Since the imminent conclusion of any movement reactualizes the circumstances of its beginning, renewed attention was drawn to what was happening within and to the Vienna Circle. (shrink)

Sequential action makes up the bulk of human daily activity, and yet much remains unknown about how people learn such actions. In one motor learning paradigm, the serial reaction time (SRT) task, people are taught a consistent sequence of button presses by cueing them with the next target response. However, the SRT task only records keypress response times to a cued target, and thus it cannot reveal the full time‐course of motion, including predictive movements. This paper describes a mouse (...) class='Hi'>movement trajectory SRT task in which the cursor must be moved to a cued location. We replicated keypress SRT results, but also found that predictive movement—before the next cue appears—increased during the experiment. Moreover, trajectory analyses revealed that people developed a centering strategy under uncertainty. In a second experiment, we made prediction explicit, no longer cueing targets. Thus, participants had to explore the response alternatives and learn via reinforcement, receiving rewards and penalties for correct and incorrect actions, respectively. Participants were not told whether the sequence of stimuli was deterministic, nor if it would repeat, nor how long it was. Given the difficulty of the task, it is unsurprising that some learners performed poorly. However, many learners performed remarkably well, and some acquired the full 10‐item sequence within 10 repetitions. Comparing the high‐ and low‐performers’ detailed results in this reinforcement learning (RL) task with the first experiment's cued trajectory SRT task, we found similarities between the two tasks, suggesting that the effects in Experiment 1 are due to predictive, rather than reactive processes. Finally, we found that two standard model‐free reinforcement learning models fit the high‐performing participants, while the four low‐performing participants provide better fit with a simple negative recency bias model.

The teikei movement is a Japanese version of the alternative food movement, which emerged around the late 1960s and early 1970s. Similar to now well-known Community Supported Agriculture, it is a farmer-consumer partnership that involves direct exchanges of organic foods. It also aims to build a community that coexists with the natural environment through mutually supportive relationships between farmers and consumers. This article examined the history of the teikei movement. The movement began as a reaction to (...) negative impacts of mechanized and chemically intensive agriculture promoted by the Japanese government. The movement experienced a rapid expansion in the early 1980s, and then gradually declined thereafter. The organic market expansion and certification system intersected with both cultural and gender role changes, impacting the teikei movement negatively. Consequently, the membership of teikei consumer groups has shrunk. Furthermore, the March 2011 Fukushima Daiichi nuclear power plant accident caused unprece dented damage to organic farmers in the affected regions. Despite the scientific uncertain about the safety level of radiation exposure, the organic farmers and the teikei consumer groups managed the situation and found a way to inspect radiation contamination. They did so with the support by networking with other teikei-related actors. This response to the nuclear power plant accident suggests that although the level of embeddedness presumably varies among teikei actors, ethics guided by the teikei principles are effective in forging a resilient partnership between farmers and consumers and in keeping the teikei system alive as an agent for social change.

The reproducibility movement in psychology has resulted in numerous highly publicized instances of replication failures. The goal of the present work was to investigate people’s reactions to a psychology replication failure vs. success, and to test whether a failure elicits harsher reactions when the researcher is a woman vs. a man. We examined these questions in a pre-registered experiment with a working adult sample, a conceptual replication of that experiment with a student sample, and an analysis of (...) data compiled and posted by a psychology researcher on their public weblog with the stated goal to improve research replicability by rank-ordering psychology researchers by their “estimated false discovery risk.” Participants in the experiments were randomly assigned to read a news article describing a successful vs. failed replication attempt of original work from a male vs. female psychological scientist, and then completed measures of researcher competence, likability, integrity, perceptions of the research, and behavioral intentions for future interactions with the researcher. In both working adult and student samples, analyses consistently yielded large main effects of replication outcome, but no interaction with researcher gender. Likewise, the coding of weblog data posted in July 2021 indicated that 66.3% of the researchers scrutinized were men and 33.8% were women, and their rank-ordering was not correlated with researcher gender. The lack of support for our pre-registered gender-replication hypothesis is, at first glance, encouraging for women researchers’ careers; however, the substantial effect sizes we observed for replication outcome underscore the tremendous negative impact the reproducibility movement can have on psychologists’ careers. We discuss the implications of such negative perceptions and the possible downstream consequences for women in the field that are essential for future study. (shrink)

Sociology is becoming fragmented. With specialised fields spinning off beyond the capacity of a unifying theoretical frame to embrace them, the prospect exists that sociology's vital centre may not hold. Proceeding from a social constructionist perspective, this work examines the existence and probes the origins of the specialised sociological fields of social problems and social movements. Conceptual ambiguities that currently plague both specialisations are noted, as are their effective theoretical isolation from general sociological theory. Each field is traced to its (...) roots in sociology's formative period in the nineteenth century. Two modes of doing sociology are found to have evolved, respectively, in the United Stales and in Continental Europe, each conditioned by distinctive historical experiences and resonating with the prevailing social and political concerns on the two continents. American sociology emerged in response to social perceptions that progress is inhibited by a proliferation of 'social problems'. Continental European sociology arose in reaction to Enlightenment principles failing to be institutionalised, inviting the perceived social threat of either revolution or anarchy. Both sociologies are thus seen as ideologically contaminated, and their respective dominant perspectives, through the 1950s, are contrasted as the 'social problem orientation' and the 'social movement orientation'. Comparative analysis of these orientatations probes such issues as ahistorical vs. historical treatments: methodological individualism vs. collectivism: differential conceptions of class; the discipline's need to inhibit ideological contagion through a sociological reconstruction of prevailing social constructions of reality; the vital distinction between structural and processual conceptualisations. The study concludes that temporality serves as a crucial but much-neglected dimension in much of American sociology. So-called social problems and social movements are found to be grounded in essentially similar empirical social circumstances, with their alternate conceptualisations attributable to differential time-frames through which such circumstances are sociologically apprehended. This points to the potential theoretical integration of these two fields. Scientific, ideological. and social policy implications of alternative constructions of reality are also explored. (shrink)

To evoke the impression of movement in the “immobile” image is one of the central motivations of the visual art, and the activating effect of images has been discussed in art psychology already some hundred years ago. However, this topic has up to now been largely neglected by the researchers in cognitive psychology and neuroscience. This study investigates – from an interdisciplinary perspective – the formation of lateralised instances of motion when an observer perceives movement in an image. (...) A first step was to identify images that evoke a perception of movement in a certain direction and to give this a rating. Reaction times leading to the engagement of a joystick following the presentation of images are used to evidence the postulated movement occasioned by the perception of movement in an image. Where the required direction of joystick moves matched the expected perception of movement direction in the image, considerably shorter reaction times were recorded. The experiment was able to prove a “movement-image compatibility effect” in observers of images. Based on this, the paper revisits and brings up to date the theses on motor sensory response to images which were developed in art psychology at the beginning of the 20th century. It furthermore contributes an embodiment theory interpretation to the prevalent representational explanation of compatibility effects. (shrink)

Communication strategies to shape public opinion can be applied to the philosophical program of conceptual engineering. I propose to look for answers to the implementation challenge for conceptual engineering on similar challenges that arise in other contexts, such as that of social movements. I claim that conceptual engineering is successfully practiced in other areas with direct consequences on the political landscape, and that we can apply to philosophy what we might learn from those successful practices. With that end in mind, (...) I explain the psychological approach to conceptual engineering. I present what has been called “the implementation challenge”, which is the problem that emerges from the possibility of control over the content of our concepts. The challenge consists in that if there is not such a control, conceptual engineering is not implementable. Then, I review some of the reactions that have been given to that challenge, and I defend the feasibility of conceptual engineering appealing to the collective action frames that social movements endorse as an instance of a successful kind of conceptual engineering and derive some strategies that might be of use for conceptual engineering in philosophy. Finally, I reply to some anticipated objections to my proposal. (shrink)

Although mouse‐tracking has been taken as a real‐time window on different aspects of human decision‐making processes, whether purely semantic information affects response conflict at the level of motor output as measured through mouse movements is still unknown. Here, across two experiments, we investigated the effects of semantic knowledge by predicting participants’ performance in a standard keyboard task and in a mouse‐tracking task through distributional semantics, a usage‐based modeling approach to meaning. In Experiment 1, participants were shown word pairs and were (...) required to perform a two‐alternative forced choice task selecting either the more abstract or the more concrete word, using standard keyboard presses. In Experiment 2, participants performed the same task, yet this time response selection was achieved by moving the computer mouse. Results showed that the involvement of semantic components in the task at hand is observable using both standard reaction times (Experiment 1) as well as using indexes extracted from mouse trajectories (Experiment 2). In particular, mouse trajectories reflected the response conflict and its temporal evolution, with a larger deviation for increasing word semantic relatedness. These findings support the validity of mouse‐tracking as a method to detect deep and implicit decision‐making features. Additionally, by demonstrating that a usage‐based model of meaning can account for the different degrees of cognitive conflict associated with task achievement, these findings testify the impact of the human semantic memory on decision‐making processes.

Animal rights organizations in the United States are predominantly female and middle class. What are the implications of the composition of these groups for animal rights activists' abilities to achieve their goals? In this article, the author examines the role of class and gender in the outcomes of an anti-hunting campaign and an anti-circus campaign waged by one animal rights organization in the Seattle area. The article shows that hunters make classed and gendered attributions about the activists, whereas circus patrons (...) do not view activists in terms of these statuses and end up taking their demands more seriously. It is suggested that an “identity interaction” between the activists' class and gender identity and that of their targets helps to explain these different reactions. The analysis also highlights the role of emotion in social movements, especially the ways in which targets perceive and react to activists' emotional displays. (shrink)

The translocation of tRNAs through the ribosome proceeds through numerous small steps in which tRNAs gradually shift their positions on the small and large ribosomal subunits. The most urgent questions are: (i) whether these intermediates are important; (ii) how the ribosomal translocase, the GTPase elongation factor G (EF‐G), promotes directed movement; and (iii) how the energy of GTP hydrolysis is coupled to movement. In the light of recent advances in biophysical and structural studies, we argue that intermediate states (...) of translocation are snapshots of dynamic fluctuations that guide the movement. In contrast to current models of stepwise translocation, kinetic evidence shows that the tRNAs move synchronously on the two ribosomal subunits in a rapid reaction orchestrated by EF‐G and GTP hydrolysis. EF‐G combines the energy regimes of a GTPase and a motor protein and facilitates tRNA movement by a combination of directed Brownian ratchet and power stroke mechanisms. (shrink)

In an experimental study of humans reactions to social motor intention in a humanoid robot, we showed that SMI cause the emergence of social interaction between human and robot. We investigated whether people would respond differently to a humanoid robot depending on the kinematic profile of its movement. A robot placed a block on a table in front of a human subject in three different ways. We designed the robot’s arm and upper body movements to manifest the human (...) kinematic profile of either a non-social motor intention or a social motor intention. In the control condition the robot performed an irregular movements. Once the robot had finished its task, the task of the human was to place another block on top of the first one. We distinguishedbetween social and non-social responses to the robot’s behavior based in gaze behavior and kinematic profile of the human’s arm movement during the task. Our results show that the behavior of the human can be modulated by the kinematics of a robot’s motor action. In several cases the participants reciprocated movements displaying social motor intention with movements with a similar kind of kinematics, attempting to make eye contact during the task. This shows that HRI can emerge implicitly by sensorimotor processing and suggests that implementing a mechanism for social-motor intention in social robots designed to interact spontaneously would be useful.

We demonstrate “economies of experience” in eye-movement patterns—that is, optimization of eye-movement patterns aimed at more efficient and less costly visual processing, similar to the priming-induced formation of sparser cortical representations or reduced reaction times. Participants looked at Mooney-type, degraded stimuli that were difficult to recognize without prior experience, but easily recognizable after exposure to their undegraded versions. As predicted, eye-movement dispersion, velocity, and the number of fixations decreased with each stimulus presentation. Further analyses showed that this (...) effect was contingent on recognition, and the selection of information from the stimulus could be informed by the identity of the presented object. Finally, our study demonstrates that after exposure to the undegraded version of the stimulus, eye-movement patterns associated with its degraded and undegraded versions become more similar. This suggests that eye-movement patterns can evolve to facilitate the optimal processing of a given stimulus via experience-driven perceptual learning. (shrink)

Reactions to these changes frequently involve returning to certain forms of behavior or responses that were common in the past but have been later (...) abandoned.

This article examines the role of the Spanish Atomic Forum as the representative of the nuclear sector in the public arena during the golden years of the nuclear power industry from the 1960s to 1970s. It focuses on the public image concerns of the Spanish nuclear lobby and the subsequent information campaigns launched during the late 1970s to counteract demonstrations by the growing and heterogeneous anti-nuclear movement. The role of advocacy of nuclear energy by the Atomic Forum was similar (...) to that in other countries, but the situation in Spain had some distinguishing features. Anti-nuclear protest in Spain peaked in 1978 paralleling the debates of a new National Energy Plan in Congress, whose first draft had envisaged a massive nuclearization of the country. We show how the approval of the Plan in July 1979, with a significant reduction in the nuclear energy component, was influenced by the anti-nuclear protest movements in Spain. Despite the efforts of the Spanish Atomic Forum to counter its message, the anti-nuclear movement was strengthened by reactions to the Three Mile Island accident in March 1979. (shrink)

In discussing the origins of the antievolution movement in American high schools within the framework of science and religion, much is overlooked about the influence of educational trends in shaping this phenomenon. This was especially true in the years before the 1925 Scopes trial, the beginnings of the school antievolution movement. There was no sudden realization in the 1920's – sixty years after the "Origin of Species" was published – that Darwinism conflicted with the Bible, but until evolution (...) was being taught in the high schools, there was no impetus to outlaw it. The creation of "civic biology" curricula in the late 1910's and early 20's, spearheaded by a close-knit community of textbook authors, brought evolution into the high school classroom as part of a complete reshaping of "biology" as a school subject. It also incorporated progressive ideologies about the purposes of compulsory public education in shaping society, and civic biology was fundamentally focused on the applications of the life sciences to human life. Antievolution legislation was part of a broader response to the ideologies of the new biology field, and was a reaction not only to the content of the new subject, but to the increasingly centralized control and regulation of education. Viewing the early school antievolution movement through the science-religion conflict is an artifact of the Scopes trial's re-creation of its origins. What largely caused support for the school antievolution movement in the South and particularly Tennessee were concerns over public education, which biology came to epitomize. (shrink)

The claim that individuals legitimately differ with respect to their values seems to be uncontroversial among bioethicists, yet many bioethicists nevertheless oppose right-to-try laws. This seems to be due in part to a failure to recognize that such laws are intended primarily to be political, not legal, instruments. The right-to-try movement seeks to build political support for increasing access to newly developed drugs outside of clinical trials. Opponents of right-to-try laws claim that increasing access outside of clinical trials would (...) undermine evidence-based medicine. They seek to maximize overall gains to patients by protecting them from adverse drug reactions and ensuring that drugs are more effective on average. In contrast, right-to-try activists have a point that regulatory judgments of drug safety and effectiveness impose one set of trade-offs on all individuals, regardless of their different values. That might be acceptable if determinations of safety and effectiveness were black and white, but that does not seem to be the case. This article argues that judgments of safety and effectiveness are in an important respect normative and reflect the perceived value of those ends relative to others. Such judgments, when universally imposed, harm patients who would readily make do with less knowledge of drug safety and effectiveness in exchange for more time and self-determination. The relevant moral principle is that of respect for individual autonomy. Just as that principle should lead one to substitute collective decisions for individual ones to regulate a natural monopoly, the same principle should lead one to substitute individual decisions for collective ones to avoid a government monopoly on access to newly developed drugs. It is argued that reforms should increase the number of treatment options available to patients outside of clinical trials. The final section of the article discusses ways in which current regulations might be reformed so as to provide more treatment options outside of clinical trials, without undermining evidence-based medicine.

Introduction: The effect of promoting a physical reaction by the described action is called the action-sentence compatibility effect. It has been verified that physical motion changes depending on the time phase and grammatical expression. However, it is unclear how adverbs and onomatopoeia change motion simulations and subsequent movements.Methods: The subjects were 35 healthy adults. We prepared 20 sentences each, expressing actions related to hands and feet. These were converted into 80 sentences, with the words “Slow” or “Quick” added to the (...) words related to the speed of movement, and 80 sentences with the words “Fast” and onomatopoeia “Satto” added. Additionally, 20 unnatural sentences were prepared for each stimulus set as pseudo sentences. Choice reaction time was adopted; subjects pressed the button with their right hand only when the presented text was correctly understood. The reaction time and the number of errors were recorded and compared.Results: As a result of a two-way repeated ANOVA, an interaction effect was observed in RTs and NoE in set A. “Hand and Fast” had significantly faster RTs than “Hand and Slow” and “Foot and Fast.” Furthermore, “Hand and Fast” had a significantly higher NoE than others. In set B, the main effects were observed in both RTs and NoE. “Hand” and “Satto” had significantly faster RTs than “Foot” and “Quick,” respectively. Additionally, an interaction effect was observed in NoE, wherein “Foot and Satto” was significantly higher than “Hand and Satto” and “Foot and Quick.”Conclusion: In this study, the word “Fast” promoted hand response, reaffirming ACE. The onomatopoeia “Satto” was a word that conveys the speed of movement, but it was suggested that the degree of understanding may be influenced by the body part and the attributes of the subject.

We have previously shown that several brain areas are activated both during sequence learning at wake and during subsequent rapid-eye-movements (REM) sleep (Nat. Neurosci. 3 (2000) 831– 836), suggesting that REM sleep participates in the reprocessing of recent memory traces in humans. However, the nature of the reprocessed information remains open. Here, we show that regional cerebral reactivation during posttraining REM sleep is not merely related to the acquisition of basic visuomotor skills during prior practice of the serial reaction time (...) task, but rather to the implicit acquisition of the probabilistic rules that defined stimulus sequences. Moreover, functional connections between the reactivated cuneus and the striatum—the latter being critical for implicit sequence learning—are reinforced during REM sleep after practice on a probabilistic rather than on a random sequence of stimuli. Our results therefore support the hypothesis that REM sleep is deeply involved in the reprocessing and optimization of the high-order information contained in the material to be learned. In addition, we show that the level of acquisition of probabilistic rules attained prior to sleep is correlated to the increase in regional cerebral blood flow during subsequent REM sleep. This suggests that posttraining cerebral reactivation is modulated by the strength of the memory traces developed during the learning episode. Our data provide the first experimental evidence for a link between behavioral performance and cerebral reactivation during REM sleep. © 2003 Elsevier Inc. All rights reserved. (shrink)
