A unique feature of flowering plants is their ability to produce organs continuously, for hundreds of years in some species, from actively growing tips called apical meristems. All plants possess at least one form of apical meristem, whose cells are functionally analogous to animal stem cells because they can generate specialized organs and tissues. The shoot apical meristem of angiosperm plants acts as a continuous source of pluripotent stem cells, whose descendents become incorporated into organ primordia and (...) acquire different fates. Recent studies are unveiling some of the molecular pathways that specify stem cell fate in the center of the shoot apical meristem, that confer organ founder cell fate on the periphery, and that connect meristem patterning elements with events at the cellular level. The results are providing important insights into the mechanisms through which shoot apical meristems integrate cell fate decisions with cellular proliferation and global regulation of growth and development.

During postembryonic development, all organs of a plant are ultimately derived from a few pluripotent stem cells found in specialized structures called apical meristems. Here we discuss our current knowledge about the regulation of plant stem cells and their environments with main emphasis on the shoot apical meristem of Arabidopsis thaliana. Recent studies suggest that stem cells are localized in specialized niches where signals from surrounding cells maintain their undifferentiated state. In the shoot meristem, initiation of (...) stem cells during embryogenesis, regulation of stem‐cell homeostasis and termination of stem‐cell maintenance during flower development appear to primarily involve regulation of the stem‐cell niche.

The post‐embryonic architecture of higher plants is derived from the activity of two meristems that are formed in the embryo: the shoot meristem and the root meristem. The epidermis of the shoot is derived from the outermost layer of cells covering the shoot meristem through repeated anticlinal divisions. By contrast, the epidermis of the root is derived from an internal ring of cells, located at the centre of the root meristem, by a precise (...) series of both periclinal and anticlinal divisions. Each epidermis has an independent origin. In Arabidopsis the mature shoot epidermis is composed of a small number of cell types: hair cells (trichomes), stomatal guard cells and other epidermal cells. In shoots, hairs take the form of branched trichomes that are surrounded at their base by a ring of accessory cells in a sheet of epidermal cells. The root epidermis is composed of two cell types: trichoblasts that form root hair cells and atrichoblasts that form non‐hair cells. Mutations affecting both the patterning and the morphogenesis of cells in both shoot and root epidermis have recently been described. Most of these mutations affect development in a single epidermis, but at least one, ttg, is involved in development in both epidermal systems. (shrink)

Higher plant shoot meristems are multicellular structures that are the site of postembryonic organogenesis. Analysis of chimeric plants has indicated that cells in different regions of the meristem can interact with each other so that their activities are coordinated during developmental processes. Correlations have not been demonstrated between events at a molecular level and the interactions observed at a phenotypic level in chimeras. Two recent papers(1,2) address this problem by reporting that expression of the floricaula gene in one (...) region of chimeric snapdragon meristems is sufficient to promote the transition from inflorescence to floral development and to induce the expression of the downstream organ identity genes deficiens and plena throughout the meristem.

Plant hormones are signalling molecules that control growth and development. Growth of the aerial parts of higher plants requires the continuous activity of the shoot apical meristem, a small mound of cells at the apex of a plant. KNOTTED1‐like HOMEOBOX (KNOX) genes are involved in regulating meristem activity, however, little is known about how this regulation is mediated. Recent evidence suggests that KNOX transcription factors may control meristem development by regulating the balance of activities of multiple (...) hormones.

Maize develops separate male and female flowers in different locations on a single plant. Male flowers develop at the tip of the shoot in the tassel, and female flowers develop on the ears, which terminate short branches. The development of male flowers in tassels and female flowers in ears is the result of selective abortion of pistils or stamens, respectively, in developing florets. Genetic analysis has shown that stamen abortion and pistil abortion are under the control of two different (...) genetic pathways. Local levels of the plant hormone gibberellic acid determine whether or not stamens are suppressed. Pistil abortion is under the regulation of the tassel seed genes, one of which has been shown to encode a short‐chain alcohol dehydrogenase. The tassel seed genes play a role in regulating the fate of inflorescence meristems as well as pistil primordium fate. (shrink)

A revised core curriculum for medical ethics and law in UK medical schools has been published. The General Medical Council requires medical graduates to understand law and ethics and behave in accordance with ethical and legal principles. A parallel policy agenda emphasises accountability, the development of professionalism and patient safety. Given the renewed focus on teaching and learning law alongside medical ethics and the development of professional identity, this survey aimed to identify how medical schools are responding to the preparation (...) of medical students for practice in the future. Questions were asked about the location, content and methods of teaching and assessment of law in undergraduate medical education. Examples of course documentation were requested to illustrate the approaches being taken. A 76% response rate was achieved. Most responding schools integrate law teaching with medical ethics, emphasising both the acquisition of knowledge and its application in a clinical context. Teaching, learning and assessment of law in clinical attachments is much less formalised than that in non-clinical education. Coverage of recommended topic areas varies, raising questions about the degree to which students can embed their knowledge and skills in actual practice. More positively, teaching does not rely on single individuals and clear descriptions were offered for problem-based and small group case-based learning. Further research is required to explore whether there are optimum ways of ensuring that legal knowledge, and skills in its use, form part of the development of professionalism among doctors in training.

Medical councils increasingly require graduates to understand law and to practise medicine mindful of the legal rules. In the UK a revised curriculum for medical law and ethics has been published. However, coverage of law in medical education remains variable and doubts exist about how far students acquire legal knowledge and skills in its implementation. This survey of students in two UK medical schools measured their law learning and their confidence in using this knowledge. Concept maps and a self-audit questionnaire (...) were used to capture students' understanding and perceptions of this knowledge domain and self-assessments of their legal knowledge and skills. A large sample was achieved across first, second and final year students. Students agree that a sound understanding of law is essential to being a good doctor. Their perceptions of law are generally positive but the interface between the legal rules and codes of medical ethics creates difficulty. In some areas students offer relatively confident self-assessments of their legal knowledge and skills for practising law. However, levels of confidence in other areas of their law learning raise doubts about the degree to which they can advocate for and protect their patients. Conclusions are drawn about the effectiveness of students' law learning and recommendations made for further research. (shrink)

This paper draws on the experience of one research project in action to evaluate the usefulness of research ethics frameworks when the environment surrounding project negotiation, data collection and dissemination is seriously disturbed by critical incidents. The paper questions the lack of emphasis in research ethics codes on the competence and capacity of agencies when commissioning and sponsoring research. Using events that surrounded one project, the paper researches the research. It explores what impacted on the creation of the context for (...) ethical and effective research and how the researchers responded to the ethical challenges that emerged. Different theoretical understandings and ethical models are drawn upon to explore how a research team translated ethical research in theory into ethical research in practice within an organization in turmoil.

In medical education, where law and ethics are often taught simultaneously, a hidden or silent curriculum emerges strongly from research-based and descriptive reviews of practice experienced by students and qualified practitioners. In social work education, where law and ethics are more commonly taught separately, specific reference to such a curriculum does not emerge from the literature. However, evidence from reviews of social work practice points to instances of ethical and legal erosion in the context of a profession which asserts its (...) location as a moral activity and its commitment to human rights and social justice. The purpose of this article is not to systematically compare what students may be learning in and about medicine and social work. Rather, prompted by concerns expressed in medical education research, it reviews the social work evidence and why it achieves a lower profile than parallel experiences in medicine. It explores the problems encountered in practice by students and qualified social workers when drawing on their legal and ethical knowledge. It reviews the impacts of legal and values education on social work programmes. It concludes by questioning whether the initiatives to improve social work, in England specifically, by the Social Work Task Force and Social Work Reform Board are appropriately configured to address the tensions that divide recommended from actual practice.

Communities often unite during a crisis, though some cope by ascribing blame or stigmas to those who might be linked to distressing life events. In a preregistered two-wave survey, we evaluated the dehumanization of Asians and Asian Americans during the COVID-19 pandemic. Our first wave revealed dehumanization was prevalent, between 6.1% and 39% of our sample depending on measurement. Compared to non-dehumanizers, people who dehumanized also perceived the virus as less risky to human health and caused less severe consequences for (...) infected people. They were more likely to be ideologically Conservative and believe in conspiracy theories about the virus. We largely replicated the results 1 month later in our second wave. Together, many Americans dehumanize Asians and Asian Americans during the COVID-19 pandemic with related perceptions that the virus is less problematic. Implications and applications for dehumanization theory are discussed. (shrink)

Terrorism, the use of military force in Afghanistan, Iraq and Syria, and the fatal police shootings of unarmed persons have all contributed to renewed interest in the ethics of police and military use of lethal force and its moral justification. In this book, philosopher Seumas Miller analyzes the various moral justifications and moral responsibilities involved in the use of lethal force by police and military combatants, relying on a distinctive normative teleological account of institutional roles. His conception constitutes a novel (...) alternative to prevailing reductive individualist and collectivist accounts. As Miller argues, police and military uses of lethal force are morally justified in part by recourse to fundamental natural moral rights and obligations, especially the right to personal self-defense and the moral obligation to defend the lives of innocent others. Yet the moral justification for police and military use of lethal force is to some extent role-specific. Both police officers and military combatants evidently have an institutionally-based moral duty to put themselves in harm's way to protect others. Under some circumstances, however, police have an institutionally based moral duty to use lethal force to uphold the law; and military combatants have an institutionally based moral duty to use lethal force to win wars. Two key notions in play are joint action and the natural right to self-defense. Miller uses a relational individualist theory of joint actions to construct the notion of multi-layered structures of joint action in order to explicate organizational action. He also provides a novel theory of justifiable killing in self-defense. Over the course of his book, Miller covers a variety of urgent topics, such as police shootings of armed offenders, police shooting of suicide-bombers, targeted killing, autonomous weapons, humanitarian armed intervention, and civilian immunity.

“Shooting [or ‘guessing’] characters” was a game, and later a communication method, based on phonological analysis of Chinese syllables. Over time, it became used in a variety of ways, including as a teaching tool, a cipher, and a phonological writing aid for the less educated. The actual and proposed applications of one phonological game show that Chinese phonology did not just exist in books, but encompassed distinct non-written practices that were essential to its proliferation. Chinese phonology is generally studied as (...) a source for the history of the Chinese language, but it is also of interest for the history of cultural and intellectual life. (shrink)

There was a duel at dawn between A and B. A shot B, who lingered on until dusk of that day, and then died of his bulletwound. Certain background conditions are satisfied which make it right to say not just that A caused B's death but that he killed him. So, A shot B and killed him. This seems to be structurally different from "A shot B and he kicked him," but what is this structural difference? How does the shooting (...) relate to the killing? (shrink)

Shoot From The Hip - Professional Intuition In Decision-Making -/- Why do eighty percent of decision-makers say that they use intuition often or very often in their decision-making? What is intuition? How does it function? How can we achieve becoming more intuitive? How can we apply it in understanding the world and making more ethical decisions?

We provide a solution to the well-known “Shooting-Room” paradox, developed by John Leslie in connection with his Doomsday Argument. In the “Shooting-Room” paradox, the death of an individual is contingent upon an event that has a 1/36 chance of occurring, yet the relative frequency of death in the relevant population is 0.9. There are two intuitively plausible arguments, one concluding that the appropriate subjective probability of death is 1/36, the other that this probability is 0.9. How are these two values (...) to be reconciled? We show that only the first argument is valid for a standard, countably additive probability distribution. However, both lines of reasoning are legitimate if probabilities are non-standard. The subjective probability of death rises from 1/36 to 0.9 by conditionalizing on an event that is not measurable, or whose probability is zero. Thus we can sometimes meaningfully ascribe conditional probabilities even when the event conditionalized upon is not of positive finite (or even infinitesimal) measure. (shrink)

The article examines whether state officials may shoot down a hijacked airplane which carries uninvolved passengers, if it is known that the plane will be used against the lives of other human beings. In its first sections, it explains the German Federal Constitutional Court’s verdict against such a permission, and it scrutinizes the crucial arguments in this ruling. The author then extends the discussion beyond the path taken by the court. She examines the defensive claims of passengers aboard the (...) plane and the protective claims of potential victims who are present at the hijackers’ target zone. In contrast to the German Federal Constitutional Court, she concludes that state officials must take the claims of both groups of potential victims equally serious, and that such conditions allow applying a consequentialist calculus because it is the only way out of a genuine dilemma.

In lieu of an abstract, here is a brief excerpt of the content:Kennedy Institute of Ethics Journal 11.4 (2001) 391-400 [Access article in PDF] Bioethics Inside the Beltway A Shooting on Capitol Hill: "The Ruby Satellite System," Mental Illness, and Failure of the American Legal System Peter J. Cohen On 24 July 1998, Russell Eugene Weston, Jr., stormed the United States Capitol, forced his way through a security checkpoint, bypassed a metal detector, and entered the office complex of Representative Tom (...) DeLay (R-TX), the House Majority Whip (Weil 1998). During this period of terror, he shot and killed two officers of the Capitol Police and seriously wounded another as they attempted to end his foray. 1 Weston was severely wounded by several Capital police officers and taken into custody. After being treated for his injuries, he was incarcerated in the District of Columbia. 2On 5 May 1999, Weston was transferred to the Federal Correctional Institute in Butner, North Carolina (United States v. Weston, 69 F. Supp. 2d 99 (D.D.C. 1999), 103), where he remains to this day. He has neither been brought to trial nor received appropriate psychiatric therapy, but continues to be warehoused "in solitary confinement under constant observation... in a psychotic state (United States v. Weston, 255 F.3d 873; LEXIS 16851 (U.S. App. 2001b), 3-4 [LEXIS]). I will briefly detail the legal events responsible for this mad situation and suggest alternative actions that should have been taken at the very onset of the case. Early Chronology Although overtly the crime appeared to be senseless and without any conceivable motivation, Weston believed that his acts were justified and necessary. The story he told to the court-appointed forensic psychiatrist, Sally C. Johnson, M.D., 3 was that while working for NASA in the early 1980s, he had developed a "Ruby Satellite System," a powerful machine that could reverse time. With access to this system, nothing was permanent--the user could simply reverse time and exit from the current scene. However, the "System" was now controlled by cannibals who were developing and spreading "Black Heva," the deadliest disease known to [End Page 391] humankind, similar to HIV or the plague. It resulted from human corpses rotting and turning black. Time was running out, and Weston believed he had to return to override the "Ruby Satellite System" in the Capitol so that he could stem the spread of "Black Heva" and prevent world calamity. He believed that if he were tried, convicted, and even executed, he could simply time reverse himself, place himself in a safe within the Capitol, and subsequently resume his life at whatever point he chose (United States v. Weston, 206 F.3d 9 (D.C. Cir. 2000), 19-20).On 22 April 1999, the district court accepted Dr. Johnson's diagnosis that Weston suffered from paranoid schizophrenia, the symptoms of which were so severe that he would be incapable of understanding the proceedings against him and of assisting in his own defense. On this basis, the court had no difficulty in finding him incompetent to stand trial (U.S. v. Weston 1999, 102).At Weston's initial hearing, Dr. Johnson had testified that medication would be efficacious in treating Weston's delusions: [T]he standard of care in someone suffering from this type of symptom picture would be to treat them with medication.... [T]here is a good likelihood that he'll have a positive response, positive in the sense that his symptoms will diminish in response to treatment.... The potential benefits to treating the defendant far outweigh the risks.... (U.S. v. Weston 1999, 108) The defense presented no expert testimony refuting Dr. Johnson's presentation. The district court then ordered that Weston begin receiving medication in order to render him nondangerous and competent for trial (U.S. v. Weston 1999, 108-9). The Problem Weston refused to be medicated! 4 He has continued to claim that the administration of antipsychotic drugs against his will would violate his Fifth Amendment due process liberty interest in avoiding unwanted bodily intrusion and implicated...

I begin by contending that an absolute prohibition to avoid resorting to shoot-to-kill, under any circumstances, does not adequately address the considerable negative consequences that could follow. In opening up the question for debate, I seek to alert us to the risks of moral corruption in both thought and practice, but I do not take these to be unassailable. Next, I pose a set of questions in order to interrogate unsafe assumptions and to disambiguate critical language in the (...) class='Hi'>shoot-to-kill scenario. (1) How might shoot-to-kill be analogous to self-defence? (2) Should we not distinguish between reasons which could explain from those which do not justify why a suicide bomber acted as they did? (3) Must we avoid entertaining any charges of complicity on the suicide bombers’ behalf? (4) How, if at all, does racial profiling adulterate the grounds for police suspicion? (5) Does “reasonability” differ from “absolute necessity” as a precondition for enacting shoot-to-kill? And, (6), prompted by the injustice of the Jean Charles de Menezes case, can we assess the moral consequences of relocating the moment of decision from the firearms officer to their operational commander? After taking stock of the results of these enquiries, I conclude that resort to 'Kratos' rules of engagement unjustifiably raises the risk of shooting dead an innocent person, compared to the risk from harm that the general population may be reasonably expected to shoulder.

Le concept d’authenticité sert de base à la valorisation de la thématique de « l’identité » qui domine aujourd’hui. Anish Kapoor présente toutes les garanties de cette « hybridité » actuellement très à la mode.

Son slogan – « Je n’ai rien à dire » – semble confirmer ce rejet de l’authenticité.

Redéfini ainsi, le concept d’authenticité deviendrait une « règle constitutive » de notre institution. (shrink)

Apical cells are universally present in lower plants and their description has been mostly viewed morphologically as single-celled meristems. This study attempts to demonstrate that the roles of apical cells and more generally of meristems collectively are (a) often the proliferative source of all cells in a plant, (b) sometimes a formative centre in histogenesis and organogenesis and (c) always a regulatory site. As a proliferative centre it occurs as a series of apical cells through a mitotic lineage by unequal (...) divisions which includes a rotational pattern to form cells distributed according to the symmetry of its organ. As a formative centre it determines leaf arrangement in mosses and leafy liverworts as well as the root cap and gametophyte cushion in ferns. It appears initially to determine the type of organ and later the organ determines the type of apical cells within. As a regulatory centre it activates distal secondary cells to proliferate as well as inhibiting neighbouring cells from becoming apical cells to preserve the identity of an organ during its development.Based on these three roles by which apical cells can be recognized an argument can be drafted that seed plants may have apical cells, although morphologically indistinguishable from other cells, singularly or in batteries instead of possessing the traditionally described multicellular meristems.

This paper considers the concept of a good game in terms of its relation to the fair testing of relevant skills and their aesthetic values. As such, it will consider what makes football ‘the beautiful game’ and what part penalty shoot-outs play, or should play, within it. It begins by outlining and refuting Kretchmar’s proposal that games which end following the elapsing of a set amount of time, such as football, are structurally, morally and aesthetically inferior to games which (...) end following the attainment of a designated goal. Instead, it is suggested that the structural deficits of t-games are compensated by the fact that they allow for a fuller test of more valuable open skills than the closed skills that tend to define e-games, such as golf. Moreover, it is the rationing of time in t-games that provides an added aesthetic value that does not occur in e-games. Finally, it is concluded that although it may appear that the existence of the penalty shoot-out supports Kretchmar’s argu.. (shrink)

Police officers often encounter potentially dangerous situations in which they strongly rely on their ability to identify threats quickly and react accordingly. Previous studies have shown that practical experience and targeted training significantly improve threat detection time and decision-making performance in law enforcement situations. We applied 90-min traditional firearms training as a control condition and a specifically developed intervention training to police cadets. The intervention training contained theoretical and practical training on tactical gaze control, situational awareness, and visual attention, while (...) the control training focused on precision and speed. In a pre- and posttest, we measured decision-making performance as well as response preparation and execution to evaluate the training. Concerning cognitive performance training, the number of correct decisions increased from pre- to posttest. In shoot scenarios, correct decisions improved significantly more in the intervention group than in the control group. In don’t-shoot scenarios, there were no considerable differences. Concerning the training of response preparation and execution in shoot scenarios, the intervention group’s response time, but not hit time, decreased significantly from pre- to posttest. The control group was significantly faster than the intervention group, with their response and hit time remaining constant across pre- and posttest. Concerning the training of tactical action control, the intervention group performed significantly better than the control group. Moreover, the intervention group improved the tactical handling of muzzle position significantly. The results indicate that a single 90-min session of targeted gaze control and visual attention training improves decision-making performance, response time, and tactical handling of muzzle position in shoot scenarios. However, these faster response times do not necessarily translate to faster hit times – presumably due to the motor complexity of hitting an armed attacker with live ammunition. We conclude that theory-based training on tactical gaze control and visual attention has a higher impact on police officers’ decision-making performance than traditional firearms training. Therefore, we recommend law enforcement agencies include perception-based shoot/don’t-shoot exercises in training and regular tests for officers’ annual firearm requalification. (shrink)

In the wake of the Stoneman Douglas School shooting, Republican and Democratic leaders—like the American electorate they represent—remain sharply divided in their responses to gun violence. They are united in their condemnation of these mass shootings, but they disagree about whether stricter or looser gun control laws are the answer. Those on the right side of the political aisle suggest that the issue is one of mental illness rather than gun control. Conversely, those who are more liberal or progressive in (...) their political learnings are quick to condemn attempts to reframe the issue of mass shootings as a mental health problem. Both sides are wrong. Mass shootings are indeed partially a mental health problem, albeit one poorly addressed by our current laws and policies. But the solution to mass shootings also needs to consider strategies that may reduce gun violence in general. (shrink)

Manifestations of school shooting or ‘columbine’, constituted by armed mass attacks and murders in educational institutions perpetrated by adolescents, have proliferated in recent years. They are marked by their unpredictability, spontaneity and cruelty. This phenomenon has been subject to scholarly examination from various perspectives, enabling the elucidation of its multifarious traits and characteristics as a means of diagnosis and prevention. This study surveys established academic approaches to the study of school shootings (psychological, legal, sociological, semiotic, existential) and delineates their specificity (...) and scope. Drawing on analysis of incidents of school shootings in Russia from 2014-2022, key signs and tendencies in the occurrence of mass attacks on educational institutions are delineated. Adopting existential approaches in philosophy and psychology, notably the works of A. Camus, E. Fromm, M. Boss, V. Frankl and L. Berkowitz, the semantic stages and constituents of school shootings as existential crimes and subsequent suicides are elucidated. The present study aims to identify and characterise the roots and essence of school shootings ('columbine') as an existential crime type, in order to comprehend the semantic motivational origins of school shootings and analyse the ‘boundary situation’ engendering individual destructive rebellion against the world. The nexus between unresolved existential needs and quandaries of the individual and the factors triggering self-destructive personality mechanisms is expounded, whereby the individual enacts an ‘escape’ from reality against the backdrop of media-disseminated aggressiveness and legitimation of violence as a means of overcoming problems and self-presentation. The existential analysis and modelling of school shooters’ actions offered here has enabled conclusions to be drawn regarding potential countermeasures to such crimes. (shrink)

In Elephant , director Gus Van Sant dramatises a massacre at a suburban American high school in order to examine narrative cinema's ethical capacity to respond to that which resists being framed as a meaningful event. In the film, this stubborn stuff is experience shot through with contingency. Van Sant depicts acts of violence that are indiscriminate and, at best, ambiguously motivated, as well as school-day activities that appear coincidental and insignificant. This essay argues that the director aims to screen (...) contingency to mount a critique of conventional narrative film's terror of contingency, its anxious drive to convert all cinematic time to good, signifying use. It also argues that Van Sant complicates or crosses up this aim by constructing a self-reflexive text attuned to the inherent irresponsibility in assuming that radical contingency's dead time could be fully and faithfully animated on screen. While the film camera and a still camera used by a student photographer in the film shoot people with the ostensible aim of capturing contingency in all its otherness, both projects are, at the same time, linked, in complex ways, to the student killers who shoot people with the aim of eliminating all otherness. The film's recognition of its own drive to plot in a deadly fashion thus illustrates Van Sant's profound sensitivity to the challenges of responding responsibly to a time of terror and, more broadly, to the terrors of time.

Nietzsche is known as a great and poignant critic of the Judeo-Christian virtue and morality, but the motivation and aim of his criticisms might sometimes remain unclear. For instance, in _Twilight of the Idols_, he writes: “Are we harming virtue, we immoralists? – Just as little as anarchists _harm_ princes. Princes sit securely on their thrones only after they've been shot at. Moral: _morality must be shot at_.” This saying seems to suggest that Nietzsche criticized and attacked traditional virtue and (...) morality in order to consolidate and strengthen them. In the article, I provide an interpretation of this saying and, in the course of it, approach Nietzsche’s reconceptualization of virtue and morality more generally. (shrink)

Previous literature on shooting performance neurofeedback training (SP-NFT) to enhance performance usually focused on changes in behavioral indicators, but research on the physiological features of SP-NFT is lacking. To explore the effects of SP-NFT on trainability and neuroplasticity, we conducted a study in which 45 healthy participants were randomly divided into three groups: based on sensory-motor rhythm of C3, Cz and C4 (SMR group), based on alpha rhythm of T3 and T4 (Alpha group), and no NFT (control group). The training (...) was performed for six sessions for 3 weeks. Before and after the SP-NFT, we evaluated changes in shooting performance and resting electroencephalography (EEG) frequency power, participant’s subjective task appraisal, neurofeedback trainability score, and EEG feature. Statistical analysis showed that the shooting performance of the participants in the SMR group improved significantly, the participants in the Alpha group decreased, and that of participants in the control group have no change. Meanwhile, the resting EEG power features of the two NFT groups changed specifically after training. The training process data showed that the training difficulty was significantly lower in the SMR group than in the Alpha group. Both NFT groups could improve the neurofeedback trainability scores and change the feedback features by means of their mind strategy. These results may provide evidence of trainability and neuroplasticity for SP-NFT, suggesting that the SP-NFT is effective in brain regulation and thus provide a potential method to improve shooting performance.

Unpleasant sensations possess a unique ability to make certain aversive actions seem reasonable to us. But what is it about these experiences that give them that ability? According to some recent evaluationist accounts, it is their representational content: unpleasant sensations represent a certain event as bad for one. Unfortunately evaluationism seems unable to make sense of our aversive behavior to the sensations themselves, for it appears to entail that taking a painkiller is akin to shooting the messenger, and is every (...) bit as unreasonable. In this paper I distinguish two versions of the shooting-the-messenger challenge: First, how do we account for the badness of unpleasant sensation? And second, how do we account for our access to that badness? I suggest plausible responses to the first question, but I also argue that the seriousness of the second has not been appreciated. I then propose a solution to the second: when we introspect our pains we also turn our emotional distress inwards, enabling them to represent our pains as bad. (shrink)

Visually traces the construction of American masculinity following World War II.

Mass shootings constitute a recurrent and most violent phenomenon in the U.S. and elsewhere. This paper challenges the ready-made, solipsistically contained metanarratives on offer by mainstream media and formal institutions with regard to the psychological antecedents of the perpetrating social actors, while theorizing mass shootings as acts of violence that are systemically inscribed in the foundations of communities. These foundations abide by the logic of sacrifice which is propagated in instances of collective traumatism. It is argued that the cultural trauma (...) that emanates from events of mass shootings, inasmuch as the commemorative events that are performed on regular occasions, constitute re-enactments of the death drive that sustains communities. The cultural analytic deploys against a CDA reading of longitudinal studies on mass shootings, coupled with psychoanalytic discourse analysis, prior to submitting mass shootings to a deconstructive line of reasoning as systemically necessary transcendental violence. Ultimately, it is shown that the intertextual institutional chain that informs the mediatized representation of this social phenomenon merely attains to obliterate and, hence, to propagate cultural traumatism and the sacrificial logic that underpins it. The terms micrometanarrative, parafunction and expropriating ipseity are introduced and operationalized in this context. (shrink)

The author of this paper was managing editor of the Journal of Consciousness Studies from its launch in 1994 until this year. As he steps down from the post, he reflects on the role of the editor, who has by turns to encourage, support, cajole, and even threaten, the team of contributors and reviewers, whose servant and master he is. What follows may be taken both as an apologia for his time in office, addressed to the consciousness community, and a (...) word of caution and advice addressed to his successor. (shrink)
