Sympatric speciation illustrates how natural and sexual selection may create new species in isolation without geographic barriers. However, recent genomic reanalyses of classic examples of sympatric speciation reveal complex histories of secondary gene flow from outgroups into the radiation. In contrast, the rich theoretical literature on this process distinguishes among a diverse range of models based on simple genetic histories and different types of reproductive isolating barriers. Thus, there is a need to revisit how to connect theoretical models of sympatric (...) speciation and their predictions to empirical case studies in the face of widespread gene flow. Here, theoretical differences among different types of sympatric speciation and speciation‐with‐gene‐flow models are reviewed and summarized, and genomic analyses are proposed for distinguishing which models apply to case studies based on the timing and function of adaptive introgression. Investigating whether secondary gene flow contributed to reproductive isolation is necessary to test whether predictions of theory are ultimately borne out in nature. (shrink)

Frank Plumpton Ramsey (1903–30) made seminal contributions to philosophy, mathematics and economics. Whilst he was acknowledged as a genius by his contemporaries, some of his most important ideas were not appreciated until decades later; now better appreciated, they continue to bear an influence upon contemporary philosophy. His historic significance was to usher in a new phase of analytic philosophy, which initially built upon the logical atomist doctrines of Bertrand Russell and Ludwig Wittgenstein, raising their ideas to a new level of (...) sophistication, but ultimately he became their successor rather than remain a mere acolyte.

O objetivo deste ensaio é examinar a recente crítica de Maria Lasonen-Aarnio à solução anulabilista do paradoxo do dogmatismo. Tal paradoxo consiste no argumento de que certos princípios epistêmicos autorizam qualquer sujeito cognoscente a desconsiderar contraevidências para o que ele sabe. Porém, esta atitude dogmática é comumente julgada como injustificada e o sujeito que a toma é comumente julgado como irracional. A solução anulabilista do paradoxo do dogmatismo foi posta em circulação por Gilbert Harman e sugere que o problema (...) é resolvido assim que se abandona a suposição de que o conhecimento não pode ser derrotado por contraevidências. Lasonen-Aarnio acredita que tal solução é insatisfatória porque ainda haveria, em certas circunstâncias, justificação para ser dogmático mesmo admitindo e sofrendo derrota epistêmica. Desse modo, a solução anulabilista deixa ainda alguma medida de dogmatismo autorizada para o sujeito. Iniciaremos com uma introdução ao problema, explicando em que consiste o paradoxo do dogmatismo e expondo as diferentes versões nas quais foi apresentado. Em seguida, vamos nos voltar para uma versão do argumento pró-dogmatismo. Consideraremos, então, a solução anulabilista proposta por Harman e a crítica de Lasonen-Aarnio. Por fim, apresentaremos três objeções à eficácia da crítica de Lasonen-Aarnio. (shrink)

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: -/- The main aim of this review will be to assess the effects of changing practitioner empathy or patient expectations for all conditions. The main objective is to conduct a systematic review of randomised trials where the intervention involves manipulating either (a) practitioner empathy or (b) patient expectations, or (c) both.

The present study examined whether strategy moderated the relationship between visuospatial perspective-taking and empathy. Participants undertook both a perspective-taking task requiring speeded spatial judgements made from the perspective of an observed figure and the Empathy Quotient questionnaire, a measure of trait empathy. Perspective-taking performance was found to be related to empathy in that more empathic individuals showed facilitated performance particularly for figures sharing their own spatial orientation. This relationship was restricted to participants that reported perspective-taking by mentally transforming their spatial (...) orientation to align with that of the figure; it was absent in those adopting an alternative strategy of transposing left and right whenever confronted with a front-view figure. Our finding that strategy moderates the relationship between empathy and visuospatial perspective-taking enables a reconciliation of the apparently inconclusive findings of previous studies and provides evidence for functionally dissociable empathic and non-empathic routes to visuospatial perspective-taking.

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

This theoretical paper proposes a new perspective to understand the moral distress of nurses more fully, using virtue ethics. Moral distress is a widely studied subject, especially with respect to the determination of its causes and manifestations. Increasing the theoretical depth of previous work using ethical theory, however, can create new possibilities for moral distress to be explored and analyzed. Drawing on more recent work in this field, we explicate the conceptual framework of the process of moral distress in nurses, (...) proposed by Ramos et al., using MacIntyrean virtue ethics. Our analysis considers the experience of moral distress in the context of a practice, enabling the adaptation of this framework using virtue ethics. The adoption of virtue ethics as an ethical perspective broadens the understanding of the complexity of nurses’ experiences of moral distress, since it is impossible to create a ready model that can cover all possibilities. Specifically, we describe how identity, social context, beliefs, and tradition shape moral discomfort, uncertainty, and sensitivity and how virtues inform moral judgments. Individuals, such as nurses, who are involved in a practice have a narrative history and a purpose ( telos) that guide them in every step of the process, especially in moral judgment. It is worth emphasizing that the process described is supported by the formation of moral competence that, if blocked, can lead to moral distress and deprofessionalization. It is expected that nurses seek to achieve the internal good of their practice, which legitimizes their professional practice and supports them in moral decision-making, preventing moral distress.

Recent EEG studies on the early postmortem interval that suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans reinforce the need for further investigation of the relationship between the brain’s activity and the dying process. Neuroscience is now in a position to empirically evaluate the extended process of dying and, more specifically, to investigate the possibility of brain activity following the cessation of cardiac and respiratory function. Under the direction of the Center for Healthy (...) Minds at the University of Wisconsin-Madison, research was conducted in India on a postmortem meditative state cultivated by some Tibetan Buddhist practitioners in which decomposition is putatively delayed. For all healthy baseline and postmortem subjects presented here, we collected resting state electroencephalographic data, mismatch negativity, and auditory brainstem response. In this study, we present HB data to demonstrate the feasibility of a sparse electrode EEG configuration to capture well-defined ERP waveforms from living subjects under very challenging field conditions. While living subjects displayed well-defined MMN and ABR responses, no recognizable EEG waveforms were discernable in any of the tukdam cases. (shrink)

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. . Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks.

Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes (...) of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.

At the centenary of the creation of Diary of a Newlywed Poet, this paper elaborates on its metaphysical discovery. Building on the relevant concepts of the poet's aesthetics, it discovers the search for meaning in the poems in the light of sensitive enrichment, the understanding of reality and the stimulation of the receiver's conscience. The study was performed in the triple sense of cultivation, term under which the poet held a theory of human development, as cultivation of sensitivity, intelligence and (...) conscience. (shrink)

Diplomat, bureaucrat, and practical politician, Niccolò Machiavelli served as Second Secretary to the Republic of Florence in the early sixteenth century and became the first major political thinker in the western tradition to make a complete break with the Aristotelian model of politics as a branch of ethics. While _The Prince _is his most famous work, grounding his reputation as the progenitor of "Realpolitik," his many other writings have contributed to a more complex and broader image of the man and (...) his political thought. Thus in recent years Machiavelli has come to be seen as a republican and a proto-liberal by some mainstream political theorists, and as an obfuscator of traditional values and ideologies, including gender roles, by feminists and non-feminists alike. The contributors to this volume, grappling with questions about the position of women in political society, investigate whether or not Machiavelli was truly a misogynist and a proto-fascist or instead a proto-feminist and a democratic republican. Among the themes they explore are the implications of such dichotomies as _Fortuna_ and _virtù_, the public and the private, nature and reason, ends and means, functionality and the common good, as well as the importance of the military to the socialization of citizens, particularly women, to civic life, and the social construction of gender. Some of the contributors even consider the possibility that Machiavelli's approach to ethics provides a special insight that feminists, and women generally, might explore to their benefit. Besides the editor, the contributors are Wendy Brown, Jane Jaquette, Donald McIntosh, Melissa Matthes, Vesna Marcina, Martin Morris, Cary Nederman, Andrea Nicki, Mary O'Brien, Hanna Pitkin, Arlene Saxonhouse, John Shin, R. Claire Snyder, and Catherine Zuckert. (shrink)

Tobacco mosaic virus has served as a model organism for pathbreaking work in plant pathology, virology, biochemistry and applied genetics for more than a century. We were intrigued by a photograph published in Phytopathology in 1934 showing that Tabasco pepper plants responded to TMV infection with localized necrotic lesions, followed by abscission of the inoculated leaves. This dramatic outcome of a biological response to infection observed by Francis O. Holmes, a virologist at the Rockefeller Institute for Medical Research, was used (...) to score plants for resistance to TMV infection. Our objective was to gain a better understanding of early to mid-twentieth century ideas of genetic resistance to viruses in crop plants. We investigated Holmes’ observation as a practical exercise in reworking an experiment, having been inspired by Pamela Smith’s innovative Making and Knowing Project. We had a great deal of difficulty replicating Holmes’ experiment, finding that biological materials and experimental customs change over time, in ways that ideas do not. Using complementary tools plus careful study and interpretation of the original text and figures, we were able to rework, yet only partially replicate, this experiment. Reading peer-reviewed manuscripts that cited Holmes’ 1934 report provided an additional level of insight into the interpretation and replication of this work in the decades that followed. From this, we touch on how experimental reworking can inform our strategies to address the reproducibility “crisis” in twenty-first century science. (shrink)

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

En este texto partiremos de la conocida tensión cinematográfica entre la imagen y la narración, refiriendo a un caso concreto de cine mexicano tipológico costumbrista. Es un género que se distingue por una trama débil constituida por secuencias con un importante peso mostrativo o “descriptivo”, más que narrativo y el espectador se entretiene en el reconocimiento de los estereotipos, obteniendo un goce mimético de reconocimiento. Para abordar tal reconocimiento mimético distinguiremos entre los imaginarios literarios y los imaginarios fílmicos. Los imaginarios (...) literarios son esquemas faltos de concreción. Por el contrario, los imaginarios fílmicos no son lo absoluto una cuestión de la imaginación más o menos vaga, sino que dada su base fotográfica presentan girones de la realidad tal cual es en su apariencia. Este imaginario fílmico ya no consta de imágenes de la mera imaginación, al gusto del que se las imagina, sino que consta de fragmentos fotográficos de la apariencia real, por lo que esas imágenes de calidad fotográfica tienden a generan de inmediato aprobación o rechazo. Puede ser que se lea algo que no gusta y entonces tiende a dejarse de lado, pero es más difícil dejar de lado algo que, aunque no guste no se leyó sino se vio. Para analizar el género de narrativa débil tipologizante recurrimos a la teoría de D. Bordwell sobre la construcción de la historia combinándola con la teoría de R. Barthes acera de los núcleos, catálisis, informantes e indicios narrativos. (shrink)

This article investigates the place of trust in learning relations in the classroom, not only between teacher and student, but also between student and student. To do this, it will first examine a pedagogy called community of inquiry, espoused by John Dewey and used in most Philosophy for Children courses in Australia. It will then consider what different forms of trust are involved in other power relations in the classroom, particularly the rational structuralism of R.S Peters, or the experiential philosophy (...) of Maria Montessori. It concludes that a community of inquiry shifts the ethical learning relation in significantly different ways because for educational growth, it values ethical trust more highly than a strategic trust in logical principle, duty, Truth, or cost/benefit analysis.

Scopo del saggio è confrontare alcune tra le principali visiones della letteratura occidentale – tra cui la Visio Pauli e la Commedia – e le diverse redazioni della tradizione islamica dell’ascensione celeste e viaggio oltremondano del profeta Muhammad, nel tentativo di stabilire se le affinità, tematiche e strutturali, osservabili tra i due gruppi di testi siano frutto di semplice poligenesi o vadano piuttosto spiegate con rapporti di effettiva intertestualità.Tra le visiones, la tradizione mirajica e la Commedia si instaura dunque un (...) dialogo a tre voci, o di sinfonia, i cui temi principali si arricchiscono e si richiamano a vicenda. Dante, primo comparatista, è in grado di reinventare, armonizzandoli, elementi strutturali e tematici provenienti sia dalle visiones latine che dalla tradizione islamica del Isra’ wa’ l Mi‘râj.The purpose of this essay is to make a confrontation between the main important visiones of the Occidental Literature – also the Visio Pauli and the Dante’s Commedia – anche the various redactions of the Islamic Isra’ wa-l mi’râj. The confrontation is in order to establish if the remarked affinities are just due to polygenesis or rather caused by concrete intertestuality.Between the visiones, the mirajic tradition and the Commedia we are in front of a three voices dialogue: it’s like a symphony, in which the themes enriches themselves and, at least, the arrive to Dante for being harmonized. Dante is the first comparatist. (shrink)

There are currently two main philosophical theories of perception - Direct Realism and the Representative Theory. The former is supported by most contemporary philosophers, whereas the latter forms the groundwork for most scientific theories in this area. The paper describes a recent experiment involving retinal and cortical rivalry that provides strong empirical evidence that the Direct Realist theory is incorrect. There are of course a large number of related experiments on visual perception that would tend to lead us to the (...) same conclusion, but the experiment described in this paper does so in a singularly direct and straightforward manner. Often the most telling experiments are the simplest. (shrink)

This chapter outlines David Lewis's favored foundational account of linguistic representation, and outlines and briefly evaluates variations and modifications. It gives an opinionated exegesis of Lewis's work on the foundations of reference: his interpretationism. The author looks at the way that the metaphysical distinction between natural and non‐natural properties came to play a central role in his thinking about language. Lewis's own deployment of this notion has implausible commitments. The chapter briefly considers a buck‐passing strategy involving fine‐grained linguistic conventions. Lewis (...) was no fan of primitive intentionality. Much of the Lewisian framework remains attractive. The overall select‐and‐project method, with its promise to deal even‐handedly with all linguistic intentionality, and its epistemic tractability, should be retained. Post‐Lewisian interpretationism results from emphasizing and retaining some of the virtues of Lewis's original proposal promises (e.g. universality and epistemic tractability), while compromising on others (e.g. metaphysical principle).

Religion and spirituality (R/S) serve as coping mechanisms for circumstances that threaten people’s psychological well-being. However, using R/S inappropriately to deal with difficulties and problems in daily life may include the practice of Spiritual Bypass (SB). SB refers to avoiding addressing emotional problems and trauma, rather than healing and learning from them. On the other hand, coping strategies may be determined by the cultural context. This study aims to describe the presence of SB in individuals who may have experienced stressful (...) situations and to understand the influence of culture on SB by comparing SB in two culturally different groups. The sample consists of a total of 435 people, 262 of Honduran nationality and 173 of Spanish nationality. Both groups are approximately equivalent in age and gender. The degree of SB, stressful events, perception of social support and spiritual well-being are examined, respectively, through the Spiritual Bypass Scale, and specific items and subscales from the Social Readjustment Rating Scale, Multidimensional Scale of Perceived Social Support, and the Functional Assessment of Chronic Illness Therapy - Spiritual Wellbeing. The results showed a higher spiritual well-being and use of SB in the Honduran sample as compared to the Spanish sample, but similar social support and stressful events. Furthermore, some of the factors predicting SB were different between the two samples. While age and a greater number of R/S practices were important in both samples, for the Honduran sample the variables that best explained SB were being a Christian, having greater social support, fewer stressful events, and greater attendance at church or temple. For the Spanish sample, however, the variable that best explained SB was studying R/S texts. Therefore, SB must be understood within the culture in which it develops, since in different cultural contexts it appears to relate to differing factors. Thus, SB becomes a possible functional or dysfunctional coping strategy depending on the social context. (shrink)

This paper focuses on perception and surveys the scientific evidence that the theory of direct realism adopted by most contemporary philosophers is incorrect. This evidence is provided by experiments on the spatial and temporal "filling-in" of percepts. It also examines the myth of the projection of sensations. The conclusion is that we do not perceive the world as it actually is, but as the brain computes it most probably to be.

Representing the viewpoints of philosophers, psychologists, anthropologists, physicists, psychoanalysts, parapsychologists, psychiatrists and biologists, this volume discusses many aspects of ESP. The general theme is that the phenomena is very valid and can no longer be ignored.

This paper explores the way in which Agamben takes part in the dialogue on “impolitical communities” that was inaugurated by J. L. Nancy and was soon followed by authors like M. Blanchot, J. Derrida and R. Esposito, among others. Although Agamben’s ontological exploration of ‘whatever being,’ followed later by the political idea of form-of-life, are still very close particularly to Nancy’s work, the article will show in which ways Agamben’s view of a political coming community explores different paths and moves (...) in unusual registers, that help to understand in new ways the kind of inoperativeness involved in a contemporary rethinking of community. The notion of experience of thought as potentiality and its relationship to that “tiny displacement” of the world which Agamben seems to connect with his idea of a coming community will play a central role in the analysis.

Taking away grains from a heap of rice, at what point is there no longer a heap? It seems small changes – removing a single grain – can’t make a difference to whether or not something is a heap; but big changes obviously do. How can this be, since big changes are nothing but small changes chained together?

Are interpersonal comparisons of desire possible? Can we give an account of how facts about desires are grounded that underpins such comparisons? This paper supposes the answer to the first question is yes, and provides an account of the nature of desire that explains how this is so. The account is a modification of the interpretationist metaphysics of representation that the author has recently been developing. The modification is to allow phenomenological affective valence into the “base facts” on which correct (...) interpretation is grounded. To use this extra resource within that theory to vindicate interpersonal comparisons, we will need to appeal rational connections between level of valence and level of desire, which this paper sets out and examines.
