Elliott Sober is both an empiricist and an instrumentalist. His empiricism rests on a principle called actualism, whereas his instrumentalism violates this. This violation generates a tension in his work. We argue that Sober is committed to a conflicting methodological imperative because of this tension. Our argument illuminates the contemporary debate between realism and empiricism which is increasingly focused on the application of scientific inference to testing scientific theories. Sober’s position illustrates how the principle of actualism drives a wedge between (...) two conceptions of scientific inference and at the same time brings to the surface a deep conflict between empiricism and instrumentalism.

Priming and recollection are expressions of human memory mediated by different brain events. These brain events were monitored while people discriminated words from nonwords. Mean response latencies were shorter for words that appeared in an earlier study phase than for new words. This priming effect was reduced when the letters of words in study-phase presentations were presented individually in succession as opposed to together as complete words. Based on this outcome, visual word-form priming was linked to a brain potential recorded (...) from the scalp over the occipital lobe about 450 ms after word onset. This potential differed from another potential previously associated with recollection, suggesting that distinct operations associated with these two types of memory can be monitored at the precise time that they occur in the human brain.

The infamous “Sydney Tar Ponds” are well known as one of the largest toxic waste sites of Canada, due to almost 100 years of steelmaking in Sydney, a once beautiful and peaceful city located on the east side of Cape Breton Island, Nova Scotia. This article begins with a contextual overview of the Tar Ponds issue including a brief introduction and history and summaries of the effects on the earth, the people, and the biotic community (animals and vegetation). Then the (...) authors talk about the STS analysis approach, namely, a discussion of six systems to indicate what has been brought to the earth and mankind by technology and modern industry. The remaining part of the article describes the difficulties confronting China, some of which are similar to the ones Canada faces as a result of the Tar Ponds contamination, and summarizes some of the experiences at Tar Ponds and the lessons China can learn from Tar Ponds.

Pictures of normal brain activity during human thought can be worth a great deal. Electrophysiology and functional neuroimaging together allow both temporal and spatial dimensions of neurocognitive functions to be explored. Although these techniqueshave their limitations, the Cognitive Neuroscience approach is well-suited to pursuing questions about how words are perceived, understood, and remembered.

This article provides a much‐needed review of the neural bases of implicit statistical learning. Batterink, Paller and Reber focus on the neural processes that underpin performance in experimental paradigms employed in implicit learning and statistical learning research. An important insight is that learning across all paradigms is supported by interactions between the declarative and nondeclarative memory systems of the brain. They conclude with a helpful discussion of future directions of research.

The realist belief in the primacy of the world and its underlying structure answers the question ‘why is there something rather than nothing.’ The world, and all things contained in it exists because of God’s creative act. Personal death in Christian philosophy continues the gift of human existence by shifting that temporal existence into eternal life. The death and resurrection of Christ lays the foundation for the possibility of eternal life, while the will of God provides an answer to the (...) why of human existence. The aim of this paper is to examine the effects of the death and resurrection of Christ on the metaphysical strings of human existence. The phenomenon of human death takes place on the arms of consciousness and being’s unconcealment. The subjective correlate of human death is the irreversible loss of consciousness, while the objective correlate of human death presents as the infolding of the gift of existence, namely, of being’s unconcealment from consciousness. These correlates function as a dynamic unit to explain human death and resurrection. The attempt to justify a belief in the existence of life after death from the point of view of consciousness alone is dualistic and leads to several absurdities and confusions about the nature of the afterlife state. The explanation of the resurrection of Christ as a continuation of the dialogue between being and consciousness begun on earth avoids those absurdities while maintaining personal identity. (shrink)

Environmental ethics arises as the output of a trade-off between our rights and nature's right to life. This negotiation secures the possibility of achieving sustainable developments, if it is conducted fairly. The rights of persons are delimited by their origin, as are the rights of the other. A person is the output of relationships taking place at three levels: (1) a material self; (2) a social self; and (3) a private or internal self. Pollution and war serve as an epitaph (...) to remind us of failed ethical trade-offs in these associations. (shrink)

For a large proportion of our daily lives, spontaneously occurring thoughts tend to disengage our minds from goal-directed thinking. Previous studies showed that EEG features such as the P3 and alpha oscillations can predict mind-wandering to some extent, but only with accuracies of around 60%. A potential candidate for improving prediction accuracy is the Steady-State Visual Evoked Potential, which is used frequently in single-trial contexts such as brain-computer interfaces as a marker of the direction of attention. In this study, we (...) modified the sustained attention to response task that is usually employed to measure spontaneous thought to incorporate the SSVEP elicited by a 12.5-Hz flicker. We then examined whether the SSVEP could track and allow for the prediction of the stickiness and task-relatedness dimensions of spontaneous thought. Our results show that the SSVEP evoked by flickering words was able to distinguish between more and less sticky thinking but not between whether a participant was on- or off-task. This suggests that the SSVEP is able to track spontaneous thinking when it is strongly disengaged from the task but not off-task thought in general. Future research should determine the exact dimensions of spontaneous thought to which the SSVEP is most sensitive. (shrink)

The flow of thought is persistent, and at times merciless. Mental content is generated throughout the day and into the night, moving forward predictably at times but surprisingly at others. Understanding what influences the trajectory of thought—how thoughts continuously unfold over time—has important implications for the diagnosis and treatment of thought disorders like schizophrenia and recurrent nightmares. Here, we examine whether cognitive control restricts moment-to-moment content shifts across sleep and wakefulness, thus acting as a fundamental constraint on thought variability. Thought (...) variability was measured as the semantic incoherence between sequential thought phrases and was applied to independent datasets of dreaming and waking reports. Our results show that within both sleeping and waking reports, conditions typically marked by higher levels of cognitive control were associated with decreased thought variability (i.e., semantic incoherence). During wakefulness, on-task conditions were associated with reduced levels of thought variability compared to off-task conditions, and thought variability was greater when thoughts wandered around more freely. During sleep, lucid dreams, marked by higher levels of cognitive control, were associated with reduced levels of thought variability compared to non-lucid dreams. Together, these results suggest that cognitive control may limit thought variability across the 24-hour cycle of thought generation. Such findings are consistent with the Dynamic Framework of Thought, where mental states are expected to vary on a continuum of deliberate constraints, with lower cognitive control leading to a categorical cluster of spontaneous thought processes that includes both mind-wandering during wakefulness and non-lucid dreams during sleep. This observation has broad implications for models of cognition, specifically highlighting the continuity of cognitive processes throughout the circadian cycle and the importance of considering varying levels of thought constraint in both waking and dreaming states.

Unconscious processing of stimuli with emotional content can bias affective judgments. Is this subliminal affective priming merely a transient phenomenon manifested in fleeting perceptual changes, or are long-lasting effects also induced? To address this question, we investigated memory for surprise faces 24 h after they had been shown with 30-ms fearful, happy, or neutral faces. Surprise faces subliminally primed by happy faces were initially rated as more positive, and were later remembered better, than those primed by fearful or neutral faces. (...) Participants likely to have processed primes supraliminally did not respond differentially as a function of expression. These results converge with findings showing memory advantages with happy expressions, though here the expressions were displayed on the face of a different person, perceived subliminally, and not present at test. We conclude that behavioral biases induced by masked emotional expressions are not ephemeral, but rather can last at least 24 h. (shrink)

Drawing on the work of Fowers, Richardson, and Slife, this commentary offers an overview and critical assessment of the theory and practice of virtue ethics in psychology. The commentary highlights the importance of a hermeneutic or relational understanding of selfhood and the value of interpreting human meanings within the context of a shared tradition. I conclude with some critical remarks that focus on reconciling the assumptions of naturalism with hermeneutic philosophy, the issue of conservatism in virtue ethics, and problems of (...) access and efficacy in approaches to psychotherapy. 2012 APA, all rights reserved).

_Challenges conventional understandings of Heidegger’s account of the body._.

Heidegger’s failure to discuss ‘the body’ in Being and Time has generated a cottage industry of criticism. In his recently translated Zollikon Seminars, Heidegger provides a response to the critics by offering a thematic account of the body that is strikingly similar to Merleau-Ponty’s account in Phenomenology of Perception. In this article, I draw on the parallels between these two texts in order to see how Heidegger’s neglect of the body affects his early project of fundamental ontology and to determine (...) whether or not an account of the body is necessary to complete the project. I defend Heidegger by suggesting that any analysis of the body is ‘ontic’ or regional and is made possible only on the basis of Dasein, understood as a public ‘clearing’ or ‘there’ of intelligibility that determines in advance the way things emerge-into-presence as the kinds of things that they are. Heidegger’s core concern in Being and Time is to unearth the essential, ‘ontological-existential’, structures of Dasein that make it possible for us to begin regional investigations into the problem of the body in the first place.

In Being and Time, Martin Heidegger introduces a unique interpretation of death as a kind of world-collapse or breakdown of meaning that strips away our ability to understand and make sense of who we are. This is an ‘ontological death’ in the sense that we cannot be anything because the intelligible world that we draw on to fashion our identities and sustain our sense of self has lost all significance. On this account, death is not only an event that we (...) can physiologically live through; it can happen numerous times throughout the finite span of our lives. This paper draws on Arthur Frank’s (At the will of the body: reflections on illness. Houghton, Boston, 1991) narrative of critical illness to concretize the experience of ‘ontological death’ and illuminate the unique challenges it poses for health care professionals. I turn to Heidegger’s conception of ‘resoluteness’ (Entschlossenheit) to address these challenges, arguing for the need of health care professionals to help establish a discursive context whereby the critically ill can begin to meaningfully express and interpret their experience of self-loss in a way that acknowledges the structural vulnerability of their own identities and is flexible enough to let go of those that have lost their significance or viability.

This paper integrates personal narratives with the methods of phenomenology in order to draw some general conclusions about ‘what it means’ and ‘what it feels like’ to be depressed. The analysis has three parts. First, it explores the ways in which depression disrupts everyday experiences of spatial orientation and motility. This disruption makes it difficult for the person to move and perform basic functional tasks, resulting in a collapse or contraction of the life-world. Second, it illustrates how depression creates a (...) situational atmosphere of emotional indifference that reduces the person’s ability to qualitatively distinguish what matters in his or her life because nothing stands out as significant or important anymore. In this regard, depression is distinct from other feelings because it is not directed towards particular objects or situations but to the world as a whole. Finally, the paper examines how depression diminishes the possibility for ‘self-creation’ or ‘self-making’. Restricted by the illness, depression becomes something of a destiny, preventing the person from being open and free to access a range of alternative self-interpretations, identities, and possible ways of being-in-the-world.

One of the traditional metaphysical assumptions that Heidegger's Being and Time challenges is that the disembodied 'theoretical' standpoint has priority over the embodied 'practical' standpoint. Heidegger argues that any act of theoretical reflection is derivative of pre-reflective social practices that we are "always already" familiar with. Some contemporary critics insist they are continuing this project by exploring aspects of our concrete practices that Heidegger's analysis allegedly overlooks, particularly by focusing on the role that the body plays in everyday life. In (...) this dissertation, I address these criticisms and suggest that they contribute to Heidegger's project only on the ontic level and in no way diminish the original contribution of his philosophy. Heidegger is not overly concerned with regional investigations into the various ways that human beings meaningfully encounter things in the world. Heidegger is concerned with the being of beings , with fundamental ontology, which asks the question: "How come meaning?" Or, put in another way, "What are the conditions for the possibility of any meaning, any intelligibility whatsoever?" ;For Heidegger, human existence as Dasein is, ultimately, neither a body-subject with emotions, perceptions, instincts, or social habits nor a self-enclosed mind. Rather, Dasein is more like a 'mass' term, referring to a shared, unfolding background of cultural relations: norms, customs, institutions, historical events, and equipment. This public background is already "there," prior to the appearance of the body, and it is structured temporally, constituting a horizon, "clearing" , or "space of free play" in terms of which things can show up as meaning something to me. I argue that it is only by means of this prior clearing of intelligibility that I can make sense of my embodied practices and that bodies can initially emerge-into-presence as the kind of things that they are.

Ken Elkins retired as chief photographer of the Anniston Star in 2000, and this selection of his work demonstrates his brilliant eye for finding and capturing images of rural southern lives and landscapes in all their difficulty, candor, and humor. These are unadorned images of a timeless landscape and proud resourceful people, who know well their neighbors, honor their past, and face the tests of daily life with wit and a stoic sense of endurance.

This book is concerned with how we should think and act in our work, leisure activities, and time utilization in order to achieve flourishing lives. The scope papers range from general theoretical considerations of the value, e.g. 'What is a balanced life?', to specific types of considerations, e.g. 'How should we cope with the effects of work on moral decision-making?'.

After explaining general characteristics such as overspecification, found in the diagrams of Greek manuscripts of Euclid’s Elements, diagrams in some propositions of Book III are examined in detail. Codex P (Vat. gr. 190) and b (Bologna) are common in avoiding overspecification in a couple of propositions. However, further examination of diagrams of Book III in other manuscripts including those in the Arabic tradition, and collation of the text suggest that the common feature in the diagrams of codex P and b (...) is rather due either to independent efforts to avoid overspecification or to contamination of traditions. It is codex F (Florence, Laurenziana 28.3) that most often coincides with codex P in Book III. (shrink)

Ken Binmore's previous game theory textbook, Fun and Games, carved out a significant niche in the advanced undergraduate market; it was intellectually serious and more up-to-date than its competitors, but also accessibly written. Its central thesis was that game theory allows us to understand many kinds of interactions between people, a point that Binmore amply demonstrated through a rich range of examples and applications. This replacement for the now out-of-date 1991 textbook retains the entertaining examples, but changes the organization to (...) match how game theory courses are actually taught, making Playing for Real a more versatile text that almost all possible course designs will find easier to use, with less jumping about than before. In addition, the problem sections, already used as a reference by many teachers, have become even more clever and varied, without becoming too technical. Playing for Real will sell into advanced undergraduate courses in game theory, primarily those in economics, but also courses in the social sciences, and serve as a reference for economists.

Written in a jargon-free way, Body Matters provides a clear and accessible phenomenological critique of core assumptions in mainstream biomedicine and explores ways in which health and illness are experienced and interpreted differently in various socio-historical situations. By drawing on the disciplines of literature, cultural anthropology, sociology, medical history, and philosophy, the authors attempt to dismantle common presuppositions we have about human afflictions and examine how the methods of phenomenology open up new ways to interpret the body and to re-envision (...) therapy.

Cross‐strand disulphides (CSDs) are unusual bonds that link adjacent strands in the same β‐sheet. Their peculiarity relates to the high potential energy stored in these bonds, both as torsional energy in the highly strained disulphide linkage and as deformation energy stored in the sheet itself. CSDs are relatively rare in protein structures but are conspicuous by their presence in proteins that are involved in cell entry. The finding that entry of botulinum neurotoxin and HIV into mammalian cells involves cleavage of (...) CSDs suggests that the activity of other cell entry proteins may likewise involve cleavage of these bonds. We examine emerging evidence of the involvement of these unusual disulphides in cell entry events. BioEssays 26:73–79, 2004. © 2003 Wiley Periodicals, Inc. (shrink)

Background High levels of moral distress in nursing professionals, of which oncology nurses are particularly prone, can negatively impact patient care, job satisfaction, and retention. Aim “Positive Attitudes Striving to Rejuvenate You: PASTRY” was developed at a tertiary cancer center to reduce the burden of moral distress among oncology nurses. Research Design A Quality Improvement (QI) initiative was conducted using a pre- and post-intervention design, to launch PASTRY and measure its impact on moral distress of the nursing unit, using Hamric’s (...) Moral Distress Scale–Revised (MDS-R.) This program consisted of monthly 60-minute sessions allowing nurses to address morally distressing events and themes, such as clinicians giving “false hope” to patients or families. The PASTRY program sessions were led by certified clinicians utilizing strategies of discussion and mind-body practices. Participants Clinical nurses working on an adult leukemia/lymphoma unit. Ethical considerations This was a QI initiative, participation was voluntary, MDS-R responses were collected anonymously, and the institution’s Ethics Committee oversaw PASTRY’s implementation. Findings While improvement in moral distress findings were not statistically significant, the qualitative and quantitative findings demonstrated consistent themes. The PASTRY program received strong support from nurses and institutional leaders, lowered the nursing unit’s moral distress, led to enhanced camaraderie, and improved nurses’ coping skills. Discussion Measurement of moral distress is innately challenging due to its complexity. This study reinforces oncology nurses have measurable moral distress. Interventions should be implemented for a safe and healing environment to explore morally distressing clinical experiences. Poor communication among multidisciplinary team members is associated with moral distress among nurses. Programs like PASTRY may empower nurses to build support networks for change within themselves and institutions. Conclusion This QI initiative shows further research on moral distress reduction should be conducted to verify findings for statistical significance and so that institutional programs, like PASTRY, can be created.

Covid-19 lockdown restrictions constitute a population-wide “life-change event” disrupting normal daily routines. It was proposed that as a result of these lockdown restrictions, physical activity levels would likely decline. However, it could also be argued that lifestyle disruption may result in the formation of increased physical activity habits. Using a longitudinal design, the purpose of this study was to investigate changes in physical activity of different intensities, across individuals who differed in activity levels prior to lockdown restrictions being imposed, and (...) across three time periods: pre-, during- and post-lockdown. This study also examined the extent to which the experience of daily hassles explained any changes in physical activity. A convenience sample recruited through social media, provided data from an online survey administered during weeks 2–3 of a 5-week lockdown and 231 participants provided complete data again 6 weeks post-lockdown. Participants completed the International Physical Activity Questionnaire–Short Form and the Daily Hassles Scale. Results showed that vigorous and moderate intensity PA were significantly lower during- and post-lockdown compared to pre-lockdown in those individuals who had been highly active pre-lockdown. In contrast, for moderately active individuals pre-lockdown, vigorous and moderate intensity PA was significantly higher during-lockdown compared to pre-lockdown, and these increased levels of vigorous PA were maintained post-lockdown. Participants experienced daily hassles due to inner concerns, time pressures, family, and financial concerns to the same extent during- and post-lockdown. Those daily hassles had a small negative predictive effect on post-lockdown PA. It appears that to understand the effect of COVID-19 restrictions on PA, the activity status of individuals pre-lockdown needs to be taken into account. The daily hassles appeared to play a role in post-lockdown PA behavior, but future research should investigate why these results occurred. (shrink)
