The Brownian motion of small particles interacting with a field at a finite temperature is a well-known and well-understood phenomenon. At zero temperature, even though the thermal fluctuations are absent, quantum fields still possess vacuum fluctuations. It is then interesting to ask whether a small particle that is interacting with a quantum field will exhibit Brownian motion when the quantum field is assumed to be in the vacuum state. In this paper, we study the cases of a small charge and (...) an imperfect mirror interacting with a quantum scalar field in (1 + 1) dimensions. Treating the quantum field as a classical stochastic variable, we write down a Langevin equation for the particles. We show that the results we obtain from such an approach agree with the results obtained from the fluctuation-dissipation theorem. Unlike the finite temperature case, there exists no special frame of reference at zero temperature and hence it is essential that the particles do not break Lorentz invariance. We find that that the scalar charge breaks Lorentz invariance, whereas the imperfect mirror does not. We conclude that small particles such as the imperfect mirror will exhibit Brownian motion even in the quantum vacuum, but this effect can be so small that it may prove to be difficult to observe it experimentally.

Through qualitative surveys, a team of law students, law professors, physicians, and residents explored the perceptions of neurology residents towards referral to appropriate legal resources in an academic training program. Respondents reported feeling uncomfortable screening their patients for health-harming legal needs, which many attributed to a lack of training in this area. These findings indicate that neurology residents would benefit from training on screening for social factors that may be impacting their patients’ health.

Inhibition, an executive function, is critical for achieving goals that require suppressing unwanted behaviours, thoughts, or distractions. One hypothesis of the emotion and goal compatibility theory is that emotions of sadness and fear enhance inhibitory control. Across Experiments 1–4, we tested this hypothesis by inducing a happy, sad, fearful, and neutral emotional state prior to completing an inhibition task that indexed a specific facet of inhibition (oculomotor, resisting interference, behavioural, and cognitive). In Experiment 4, we included an anger induction to (...) examine whether valence or motivational-orientation best-predicted performance. We found support that fear and sadness enhanced inhibition except when inhibition required resisting interference. We argue that sadness and fear enhance inhibitory control aiding the detection and analysis of problems (i.e. sadness) or threats (i.e. fear) within one’s environment. In sum, this work highlights the importance of identifying how negative emotions can be beneficial for and interact with specific executive functions influencing down-stream processing including attention, cognition, and memory.

This book reclaims Hegel's notion of the "end of art"-or, more precisely, of "art's past character"-not just as a piece of the history of philosophy but as a living critical and interpretive methodology. It addresses the presence of the past character of art both in Hegel and contemporary philosophy and aesthetics. The book's innovative contribution lies in unifying the Hegelian thesis with discussions of contemporary art and philosophy. The author not only offers a Hegelian exegesis but applies the idea of (...) the past character of art to themes that are both related to Hegel's philosophy, such as the French Revolution and the modern state, Kantian aesthetics, and religion and the sacred space disclosed for art, and going beyond Hegel, such as Celan's poetry, Gramsci's criticism of Croce, human rights, and even the grunge rock band Pearl Jam. Conversely, such non-Hegelian explorations will help enlighten what may look like a specific thread of Hegel's aesthetics, but can be used to shed light on some core motives of his philosophy. The author's interpretation of art's past character reclaims the full value, attractiveness, and philosophical soundness of Hegel's thesis, while rejecting its interpretation in terms of a complete dissolution of the aesthetic element into the philosophical one. Hegel and the Present of Art's Past Character will be of interest to scholars and advanced students working on Hegel, philosophy of art and aesthetics, history of philosophy, political philosophy, and art theory.

O livro almeja ser representativo nos principais debates contemporâneos, oferecendo uma visão panorâmica sobre o campo na atualidade e permitindo-se aprofundar em algumas discussões selecionadas.O ambiente não pode ser reduzido ao “meio ambiente”, à natureza não humana. Ele não é meramente algo que “nos envolve”, um envoltório: o ambiente somos também nós, seres humanos, histórica e culturalmente situados. Quanto aos territórios, eles se estabelecem em íntima conexão com os ambientes em suas dimensões paisagística e material, quer sejam os processos geoecológicos, (...) quer sejam as formas e as dinâmicas socialmente produzidas. Analisar os territórios significa examinar como, a cada momento, os ambientes, seus recursos e significados são disputados e viram objeto de conflitos.O público-alvo principal são os estudantes dos últimos anos da graduação, além daqueles em nível de pós-graduação, de todas as áreas que lidam com problemas e conflitos ambientais. Afora os pesquisadores iniciantes e os jovens universitários em geral, porém, podemos presumir que profissionais experientes também poderão tirar proveito do material de diversos capítulos. É razoável, por fim, nutrir a expectativa de que muito do que este livro contém possa (retro)alimentar o ativismo ambiental crítico e a prática de combater as iniquidades e as distorções que se acumulam em nossas sociedades, principalmente as muitas situações de flagrante injustiça ambiental.

Research ethics education has taken many forms since federal funding agencies issued regulatory guidance directing those supported by these agencies to complete required training. In the absence of a standard training approach among institutions such as universities, the design and content of courses, workshops, and seminars varies widely. Here we describe a southwestern United States research university program that employed six teaching strategies to assist students in deep learning of ethical principles and behavior. Our purpose was to determine how these (...) strategies impact understanding and empowerment among an interdisciplinary group of graduate students. Results suggested that deep learning design can result in learning that requires students not only to remember and understand key ethics concepts but also to analyze and apply them in a broader ethical domain. Key findings inform design and delivery of future research ethics courses for instructional designers and instructors in higher education. (shrink)

Local food systems can have economic and social benefits by providing income for producers and improving community connections. Ongoing global climate change and the acute COVID-19 pandemic crisis have shown the importance of building equity and resilience in local food systems. We interviewed ten stakeholders from organizations and institutions in a U.S. midwestern city exploring views on past, current, and future conditions to address the following two objectives: 1) Assess how local food system equity and resilience were impacted by the (...) COVID-19 pandemic, and 2) Examine how policy and behavior changes could support greater equity and resilience within urban local food systems. We used the Community Capitals Framework to organize interviewees’ responses for qualitative analyses of equity and resilience. Four types of community capital were emphasized by stakeholders: cultural and social, natural, and political capital. Participants stated that the local food system in this city is small; more weaknesses in food access, land access, and governance were described than were strengths in both pre- and post-pandemic conditions. Stakeholder responses also reflected lack of equity and resilience in the local food system, which was most pronounced for cultural and social, natural and political capitals. However, local producers’ resilience during the pandemic, which we categorized as human capital, was a notable strength. An improved future food system could incorporate changes in infrastructure (e.g., food processing), markets (e.g., values-based markets) and cultural values (e.g., valuing local food through connections between local producers and consumers). These insights could inform policy and enhance community initiatives and behavior changes to build more equitable and resilient local food systems in urban areas throughout the U.S. Midwest.

Social learning has been shown to be an evolutionarily adaptive strategy, but it can be implemented via many different cognitive mechanisms. The adaptive advantage of social learning depends crucially on the ability of each learner to obtain relevant and accurate information from informants. The source of informants’ knowledge is a particularly important cue for evaluating advice from multiple informants; if the informants share the source of their information or have obtained their information from each other, then their testimony is statistically (...) dependent and may be less reliable than testimony from informants who do not share information. In this study, we use a Bayesian model to determine how rational learners should incorporate the effects of shared information when learning from other people, conducting three experiments that examine whether human learners behave similarly. We find that people are sensitive to a number of different patterns of dependency, supporting the use of a sophisticated strategy for social learning that goes beyond copying the majority, and broadening the situations in which social learning is likely to be an adaptive strategy.

In _Civilization and Its Discontents_, Freud made abundantly clear what he thought about the biblical injunction, first articulated in Leviticus 19:18 and then elaborated in Christian teachings, to love one's neighbor as oneself. "Let us adopt a naive attitude towards it," he proposed, "as though we were hearing it for the first time; we shall be unable then to suppress a feeling of surprise and bewilderment." After the horrors of World War II, the Holocaust, Stalinism, and Yugoslavia, Leviticus 19:18 seems (...) even less conceivable—but all the more urgent now—than Freud imagined. In _The Neighbor_, three of the most significant intellectuals working in psychoanalysis and critical theory collaborate to show how this problem of neighbor-love opens questions that are fundamental to ethical inquiry and that suggest a new theological configuration of political theory. Their three extended essays explore today's central historical problem: the persistence of the theological in the political. In "Towards a Political Theology of the Neighbor," Kenneth Reinhard supplements Carl Schmitt's political theology of the enemy and friend with a political theology of the neighbor based in psychoanalysis. In "Miracles Happen," Eric L. Santner extends the book's exploration of neighbor-love through a bracing reassessment of Benjamin and Rosenzweig. And in an impassioned plea for ethical violence, Slavoj Žižek's "Neighbors and Other Monsters" reconsiders the idea of excess to rehabilitate a positive sense of the inhuman and challenge the influence of Levinas on contemporary ethical thought. A rich and suggestive account of the interplay between love and hate, self and other, personal and political, _The Neighbor_ will prove to be a touchstone across the humanities and a crucial text for understanding the persistence of political theology in secular modernity.

We have arrived at an inflection point, a moment in history when the sentience, conscious- ness, intelligence, agency, and even the moral agency of many nonhuman animals can no longer be questioned without ignoring centuries of accumulated scientific knowledge. Nowhere is this more true than in our understanding of nonhuman primates (NHPs). A neu- roethics committed to probing the ethical implications of brain research must be able to respond to and anticipate the challenges ahead as brain projects globally prepare to (...) increase the use of NHPs in research. This requires adopting a less anthropocentric focus that includes nonhuman animals within its scope. But the Neuroethics Roadmap represents a missed opportunity to critically examine the future direction of research with NHPs in an ethically-responsive neuroscience. (shrink)

This paper provides a series of reflections on making the case to senior leaders for the introduction of clinical ethics support services within a UK hospital Trust at a time when clinical ethics committees are dwindling in the UK. The paper provides key considerations for those building a case for clinical ethics support within hospitals by drawing upon published academic literature, and key reports from governmental and professional bodies. We also include extracts from documents relating to, and annual reports of, (...) existing clinical ethics support within UK hospitals, as well as extracts from our own proposal submitted to the Trust Board. We aim for this paper to support other ethicists and/or health care staff contemplating introducing clinical ethics support into hospitals, to facilitate the process of making the case for clinical ethics support, and to contribute to the key debates in the literature around clinical ethics support. We conclude that there is a real need for investment in clinical ethics in the UK in order to build the evidence base required to support the wider introduction of clinical ethics support into UK hospitals. Furthermore, our perceptions of the purpose of, and perceived needs met through, clinical ethics support needs to shift to one of hospitals investing in their staff. Finally, we raise concerns over the optional nature of clinical ethics support available to practitioners within UK hospitals. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Divine Emptiness and Historical Fullness: A Buddhist-Jewish-Christian Conversation with Masao AbeEdward L. ShirleyDivine Emptiness and Historical Fullness: A Buddhist-Jewish-Christian Conversation with Masao Abe. Edited by Christopher Ives. Valley Forge, PA: Trinity Press International, 1995. 272 pp.This book is a continuation of a discussion begun by Masao Abe in 1984, previous incarnations of which have been published elsewhere. In the present volume, Abe’s expanded essay serves as the first part (...) of a four-part book. The second part includes responses by six Jewish, Christian, and Buddhist thinkers. The third part is Abe’s responses to questions and criticisms raised in Part Two. The fourth part consists of critiques by Hans Küng and Wolfhart Pannenberg and Abe’s separate responses to each.Part One consists of Abe’s well-known essay, “Kenotic God and Dynamic Sunyata.” There are many issues that Abe raises in this essay, of which only two—his understanding of a self-emptying God and his interpretation of the Holocaust—raise any serious concerns among his responders. Abe begins his theological reflection on the self-emptying of God by focusing on the kenosis hymn of Philippians 2:5–11. Abe raises the issue of the kenosis of Christ from a moral to ontological level, asking whether the self-emptying of Christ in either the Incarnation or the Crucifixion can be understood apart from the self-emptying “nature” of the Logos itself. And then, upping the ante, he asks whether one can speak of the kenosis of Christ without also speaking of the kenosis of the God whom Christ reveals.Abe then turns his attention to the Buddhist idea of Sunyata and proposes that Sunyata, far from being either a static or merely negative term, is dynamic and positive. This, he believes, will help to distinguish the Buddhist notion of Sunyata from Nietzschean nihilism. Abe also writes of the place of human reason, free will, the concept of evil, and time and history in Buddhism. It is in this context that he addresses the question of the Holocaust, speaking of his own responsibility not in the sense of having been directly involved, but in light of “collective karma.” At the same time, he does not want to suggest joint responsibility of the victims in the ethical dimension, but rather that such solidarity is realized in what he terms “the most fundamental religious dimension,” this dimension being identical with dynamic Sunyata. [End Page 207]The second part of the book consists of responses by six religious scholars. The first two respondents write from a Jewish perspective. Richard Rubenstein begins by asserting that the Philippians hymn can be understood only in light of Paul’s Jewish-Christian experience of the Covenant. Next, Rubenstein turns to his primary concern, which is Abe’s treatment of the Holocaust. He begins by outlining various Jewish responses to the Holocaust and rejecting each of them. Like Abe, Rubenstein denies the continuity of the ethical and ultimate dimensions, and accepts ultimate reality as ultimate nothingness.Sandra B. Lubarsky also appreciates Abe’s concept of Sunyata, but for different reasons than Rubenstein. Lubarsky sees it as a healthy antidote to Jewish tendencies to absolutize the Jewish community, which has led to an idolization of the community. On the other hand, she questions the Zen assumptions that lie behind Abe’s treatment of history and justice. While there is a higher vantage point than the level of human understanding from which to understand historical events, this level is reserved for God alone and to pretend to that level is arrogant. Likewise, from a Jewish perspective, it is impossible to remove God from ethical considerations.Christian responses begin with those of Heinrich Ott, who argues that the proper locus of interreligious dialogue lies not in the discussion of doctrinal or philosophical similarities, but rather in similar psychological experiences. Ott finds something in Christian experience similar to Sunyata. From this starting point, he proposes a Christian understanding of Nothingness that encompasses both human interconnectedness as well as the interconnectedness of humans with nonhuman reality.Marjorie Hewitt Suchocki maintains that speaking of the self-emptying God revealed in the self-emptying Christ has...

ShirleySt. Edward's UniversityThe annual meeting of the Society for Buddhist-Christian Studies met in Boston on Friday and Saturday, November 19 and 20, 1999. This year's papers addressed the problems of consumerism from Buddhist and Christian perspectives.In the first session, Stephanie Kaza presented a paper in which (...) she analyzed consumerism in light of Buddhist teachings. In her introduction, she offered a brief analysis of consumerist patterns in the first, third, and "fifth" worlds, paying special attention to the ecological impacts of consumerism, the formation of an ideology of consumerism, and the various players in the globalization of consumerism.In the second part of her paper, Stephanie offered an analysis of American "mall mentality" in light of the twelve links of codependent origination found in Buddhist teachings. One can enter the wheel at any point, and malls, advertising, and the entirety of consumeristic culture are designed to stimulate the birth of each of these links: malls are designed to engender craving, clinging, ignorance, and so forth. Because each link in the chain leads to the next, there ensues a "vicious cycle" from which it is difficult to escape. As one can enter the cycle at any point, however, the chain can be broken at any point as well. It was at this point that Stephanie offered a framework for liberation, noting that in Buddhism there are spiritual practices which are designed to help break the cycle at any link, and thus lead to liberation.As there was no Christian respondent, the session went immediately to group discussion, where the worldwide proliferation of "mall mentality" was explored, with the observation that malls in Asian countries are often indistinguishable from those in the United States, even housing identical stores. A sense of helplessness and frustration was expressed by many, but it was noted that each Tradition has a set of tools and resources for dealing with both the frustration as well as the disease, including teachings regarding moderation, simplicity, and restraint.In the second session, Jay McDaniel addressed consumerism from a Christian perspective. Noting that we sometimes speak of dual practice as Buddhists and Christians, he spoke of the "dual practice" of being both a consumer and a Christian. Thus, he noted, he was speaking about consumerism from the inside. Sharing a parable of an old woman and a grasshopper, Jay spoke of various dimensions of [End Page 233] Christian life, such as seeing the Divine in others, hearing and discerning an inner voice, themes of death and Resurrection, and approaching God, not as an object, but as "open space."Jay then spoke of the "Bad News" of consumeristic society, which has produced an over-consuming and "consuming" lifestyle and values to support that lifestyle. It has become, Jay argued, an unofficial religion in which economic growth has become God, and whose priests are economists, politicians and CEOs. Evangelistic advertisers draw us into the church, that is, the mall, and offer us the salvation of appearance, affluence, and marketable achievement. Creation is a collection of commodities and humans are skin-encapsulated egos.Jay then spoke of the need for Christians to respond on three levels: intellectual reflection, practical action, and spiritual discipline. For the first level, Jay emphasized a twofold approach: there is a need for historical and policy analysis as well as an explicit presentation of Christian alternative worldviews to the predominant consumerist myth. For the second level, Jay emphasized the need for social engagement to address the structural factors of consumerism. For the third level, he emphasized the need to develop a quality of heart that expresses itself in the intellectual and action arenas, particularly through a revitalization of the Christian contemplative tradition. Through daily practice of sacramental awareness (the presence of the Divine here and now), discernment, trust, and open space, through a daily practice of letting go and living the Paschal Mystery, Jay said Christians can begin to counter the lure...

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 183-187 [Access article in PDF] The 2001 Meeting of the Society for Buddhist-Christian Studies Edward L. Shirley St. Edward's University The annual meeting of the Society for Buddhist-Christian Studies met in Denver, Colorado, on Friday and Saturday, November 16 and 17, 2001. This year's papers addressed the question of "dual belonging" from both Buddhist and Christian perspectives.On Friday afternoon, two papers were delivered, the first (...) paper by Catherine Cornille, who suggested three categories of dual belonging: syncretism, drawing elements from both traditions; belief that both traditions point to a higher reality, which may not be expressible in itself; and inculturation, incorporating local symbols and rituals into a tradition that is being transplanted from elsewhere. She then focused on the issue of inculturation.Inculturation, she argued, assumed an essence of a religion that had independent existence from cultural expressions. The people involved in the process of inculturation may not, in fact, believe that they are dual practitioners, but rather that they are simply expressing the essence of a tradition through new symbols. She understands this as belonging to a symbol from one religious tradition (e.g., Christ) while using the hermeneutical tools of another.The caveat that must be acknowledged in this process, according to Cornille, is that it is impossible to separate religious developments from their roots. For example, while there has been some talk of a "Christian Vedanta," the fact is Vedanta was developed in a particular context, and cannot be separated from its Vedic roots. At the same time, however, it must be admitted that religious traditions have, in fact, historically developed in such a manner. As Cornille points out, Greek expressions are not in themselves Christian, but have in fact helped to shape Christianity, as, for example, in the Nicene Creed.Ruben Habito, who focused more on his personal journey, delivered the second paper. In his late twenties, while still in Jesuit formation, he was sent to Japan and there was introduced to the practice of Zen. He spoke of his meditation on the mu koan, and his first experience of kensho, direct insight. He went on to further koan meditation from there.As he was preparing for ordination as a Jesuit priest, he began to wonder: How did [End Page 183] he still deal with Jesus, the Trinity, Incarnation, and the Paschal Mystery if he was committed to Zen practice? He found his answer in his Jesuit training: He was being called to continued metanoia, the continual movement from self to love. In Zen terms, he was undergoing a continuing process of transformation.In Buddhism, it is said that the myriad beings are one's true self. This is the meaning of the phrase "to be awakened by the myriad beings." In the Buddhist tradition, one of those myriad beings who assist in awakening is the bodhisattva Kanzeon, the Bodhisattva of Compassion. In the Christian tradition, this function is often associated with the Virgin Mary. The iconography of these two figures is often quite similar, to the point that early Jesuits took the figure of Kanzeon to be the Virgin Mary. During times of persecution, Japanese Christians would use a double-sided figure, with Kanzeon on one side and Mary on the other. This composite of Maria-Kannon has become, for Habito, a symbol of the potential of being nourished by the two traditions.The first response was from Jay McDaniel, who drew an analogy from biology. Some trees have two sets of roots, one a deep taproot and the other a secondary root system. Could this be an image for those drawing from two paths?McDaniel's response was based on his personal encounters with two traditions. He spoke of how reading Thomas Merton twenty-five years ago changed his life and helped him overcome a fundamentalist Christian background. He spoke of how Ruben Habito has helped him understand what it means to walk two paths. Like Whitehead, he feels that he can say "yes" to both a Personal God and to the Ultimate Reality of Emptiness... (shrink)

Shirley St. Edward's University The annual meeting of the Society for Buddhist-Christian Studies met in Nashville on Friday and Saturday, November 17 and 18, 2000. This year's papers addressed the theme "Beyond the Usual Alternatives in Buddhist-Christian Dialogue," with usual alternatives being the categories of exclusivism, inclusivism, and pluralism.The (...) first session was held Friday afternoon. The first presenter, Terry Muck, spoke from a Christian perspective. He first addressed the adequacies of these three categories.Were these legitimate categories?Were they the only categories? Were there better ways to categorize theoretical positions involving the truth claims of the other? Terry suggested first that it seemed unnecessary to expand these three categories to include a fourth or fifth. Nor did he feel that it was necessary to do away with said categories altogether. He proposed, rather, that we make use of these three categories as helpful but that we be careful not to use them to label people. Indeed, he suggested, the same person might be inclusivist at one point in the dialogue but pluralist at another. It was especially important not to use these categories to dismiss another's position: "Oh, she's just an inclusivist." Terry pointed out that much of the discussion concerning the truth claims of the other were ultimately grounded in questions of soteriology: who will be saved (from a Christian perspective), or who can be liberated (from a Buddhist perspective)?The second presenter was Miriam Levering, speaking from a Buddhist perspective. In her paper, she used three medieval Chinese Buddhist teachers who seemed to represent these three categories: Kuei-feng Tsung-mi, Ch'eng-kuan, and Ta-hui Tsung-kao (with whom she also associated contemporary Buddhist teacher Thich Nhat Hanh). The three teachers were facing questions about the relationship of Buddhism to Confucianism and Taoism. Kuei-feng Tsung-mi taught that there were three types of teachings: those that were nonliberative, those that were partially liberative, and those that were fully liberative. Lao-Tzu and Confucius, he maintained, were liberated beings, but were not fully liberated. Their liberation was partial or shallow. Ta-hui Tsung-kao, on the other hand, taught that words and concepts were not as important as the experience of emptiness and non-self, which could take place outside a Buddhist context. This seems to be the position, Miriam suggested, ofThich [End Page 103] Nhat Hanh. Finally, Ch'eng-kuan taught that only Buddhism contained the truth and that the teachings of Taoism and Confucianism were poison and led one to hell.Virginia Straus responded from a Buddhist perspective. She appreciated Terry's suggestion that we shift from seeing the three categories as labeling and use them as instrumental categories: people tend to function in this way. She felt that Miriam's paper resonated with Terry's as she presented three types of teaching from within the Buddhist tradition.Virginia felt, however, that perhaps Terry had too quickly written off attempts to expand the number of categories to a set of four or five. Indeed, she pointed out, both presenters either ignored or dismissed this important work. Virginia also questioned why Terry seemed to let the positive and negative aspects of dialogue rise and fall on the question of salvation. What of David Chappell's suggestion that dialogue be based on responses to cultural and economic oppression rather than the search for truth? Global ethics, she suggested, would give a larger framework within which to dialogue.Afterwards, there was general group discussion. A question was raised as to whether there was a parallel between this discussion of dialogical positions and the debate in studies of mysticism between the perennialists and pluralists. Others questioned Thich Nhat Hanh's position that dialogue could only take place from the position of nonduality. Were these categories merely ways religious liberals had to label others? Can there be a Christian or Buddhist ethics without the experience of grace or non... (shrink)
