In Older Adults (OAs), Electroencephalogram (EEG) slowing in frontal lobes and a diminished muscle atonia during Rapid Eye Movement sleep (REM) have each been effective tracers of Mild Cognitive Impairment (MCI), but this relationship remains to be explored by non-linear analysis. Likewise, data provided by EEG, EMG (Electromyogram) and EOG (Electrooculogram)—the three required sleep indicators—during the transition from REM to Non-REM (NREM) sleep have not been related jointly to MCI. Therefore, the main aim of the study was to explore, with (...) results for Detrended Fluctuation Analysis (DFA) and multichannel DFA (mDFA), the Color of Noise (CN) at the NREM to REM transition in OAs with MCI vs. subjects with good performances. The comparisons for the transition from NREM to REM were made for each group at each cerebral area, taking bilateral derivations to evaluate interhemispheric coupling and anteroposterior and posterior networks. In addition, stationarity analysis was carried out to explore if the three markers distinguished between the groups. Neuropsi and the Mini-Mental State Examination (MMSE) were administered, as well as other geriatric tests. One night polysomnography was applied to 6 OAs with MCI (68.1 ± 3) and to 7 subjects without it (CTRL) (64.5 ± 9), and pre-REM and REM epochs were analyzed for each subject. Lower scores for attention, memory and executive funcions and a greater index of arousals during sleep were found for the MCI group. Results confirmed that EOGs constituted significant markers of MCI, increasing the CN for the MCI group in REM sleep. The CN of the EEG from the pre-REM to REM was higher for the MCI group vs. the opposite for the CTRL group at frontotemporal areas. Frontopolar interhemispheric scaling values also followed this trend as well as right anteroposterior networks. EMG Hurst values for both groups were lower than those for EEG and EOG. Stationarity analyses showed differences between stages in frontal areas and right and left EOGs for both groups. These results may demonstrate the breakdown of fractality of areas especially involved in executive functioning and the way weak stationarity analyses may help to distinguish between sleep stages in OAs.

Open peer commentary on the article “Exploring the Depth of Dream Experience: The Enactive Framework and Methods for Neurophenomenological Research” by Elizaveta Solomonova & Xin Wei Sha. Upshot: Neurophenomenology requires a first-person report at the sub-personal level. Thus, the neurophenomenology of dreaming and sleep can be figuratively located in a model of perspectives and levels of analysis. Even when Solomonova and Sha do admit creativity to explain bizarreness and emphasize dreams’ enaction and, especially, dreams’ perception-dependence, an innate and developmental framework (...) of neurophenomenology becomes a requirement to understand fully its sub-personal counterpart, i.e., sleep, especially the evidence derived from innate processing observed during the sleep of neonates - even without the dreaming counterpart. Finally, precisions about the depth of dreaming in Hobson’s work are presented. (shrink)

Dissociative symptoms are notorious for their enigmatic, disparate nature encompassing excessive daydreaming, memory problems, absentmindedness, and impairments and discontinuities in perceptions of the self, identity, and the environment. Recent studies (e.g., Koffel & Watson, 2009) have linked dissociative symptoms to vivid dreaming, nightmares, and objective sleep parameters (e.g., lengthening of REM sleep) for discussion, see (Van der Kloet et al., 2013). Germane to this link between dissociative symptomology and sleep, is the idea that in dissociative individuals, the waking state as (...) compared to REM sleep may be marked by an increase in “fluid” and hyperassociative thinking. Against this background, we invited contributions in the following areas: 1) a progressive and enduring de-differentation of wake and dream states of consciousness eventually results in schizophrenia (Llewellyn, 2011); a lesser degree of de-differentiation may have implications for dissociative symptoms; 2) sleep disturbances are not only linked to dissociation but to memory fragmentation also, further fuelling both dissociation and other manifestations of psychopathology; 3) sleep, memory and psychopathologies have complex interlinkages. Our summary below, relates the contributions to our topic to these areas. The contributing articles also give a comprehensive overview on current directions and challenges in these research fields.First, Soffer-Dudek elucidates why heightened sleep experiences (vivid dreams, nightmares, hypnagogic hallucinations) might be particularly associated with psychopathology. She explains how various psychopathologies may represent de-differentiation of the waking and dreaming states through intrusions of wake-like consciousness into sleep and dream-like cognition into wake. With regard to de-differentiation, she discusses theories of transliminality (‘thin boundaries between consciousness states’) and dissociation as potential mechanisms. Lucid dreaming is a hybrid state where wake-like cognition suffuses REM sleep/dreaming (Voss et al. 2009). Mota and colleagues compared the spontaneous occurrence of lucid dreaming in patients with psychotic symptoms (25 with schizophrenia and 20 with bipolar disorder) and 28 non-psychotic subjects. They found lucid dreaming was associated with psychosis- giving some support to the hypothesis of a link between state de-differentiation and psychopathology. In a methodological note, Ribeiro et al, having studied the prevalence of lucid dreaming using two questionnaires, show that the type of methodology used in lucid dreaming studies may have an effect upon their findings. Poerio et al state that both research and theory points to dissociation being engendered by the intrusion of dream-like mentation into waking consciousness. To extend this idea they examine the role of sleep and daydreaming as potentiating states for subsequent dissociation in depersonalization/derealization disorder (DDD). They show the occurrence and content of daydreams may act as potentiating states for heightened, in the moment, dissociation. Sleep paralysis is a dissociated state where a heightened level of wake-like alertness coexists with muscle atonia. Rodrigez de Sa and Mota-Rolim take a broad interdisciplinary perspective on sleep paralysis through reviewing its occurrence in Brazilian folklore by exploring the “Pisadeira” with a sleep science approach and link this with the field of history and art.There is now substantial evidence that active memory processing continues during sleep (see, for example, Rasch and Born (2013)) and dreaming may be involved (Llewellyn, 2013). De-differentiation of the wake, sleep and dream states would disrupt this memory processing fuelling dissociation and other psychopathologies. Horton presents an overview of discontinuity of consciousness in both wake and sleep, focusing on the processes of sleep-dependent memory consolidation and fragmentation. Nakagawa et al focus specifically on working memory and the relation with sleep. With their article, they are the first to investigate differences between verbal working memory (VWM) and visuospatial working memory (VSWM) related to daytime nap duration, nap frequency, and dream content recall frequency (DCRF). They discuss sex-related differences in the effects of sleep habits on VMW and VSWM and ascribe this to differences in underlying neural correlates, and effectiveness of sleep habits in males and females.Rosales-Lagarde and colleagues related to emotional memory by designing an extended International Affective Picture System (IAPS) instrument to measure bizarreness and show some interesting age and gender disparities. Finally, several authors took a developmental approach through focusing on sleep, memory and psychopathology in adolescents. Wang and colleagues show the relation between children and adolescents’ mental health and sleep problems in a 10-year longitudinal trial, and find anxiety, depression, attention problems and aggressive behaviour during childhood to be important predictors for later sleep problems. Importantly, sleep problems are also predictive of behavioural difficulties later in life. Nader, Murkar, and Smith investigated changes in sleep in adolescents between 12 and 19 years old following procedural task training and found that contrary to earlier work, there were no changes in sleep spindle density. Interestingly, participants who successfully learned the task showed no changes in their sleep stage proportions, but participants who were not successful showed a decrease in the proportion of Stage 2 and increases in both SWS and REM sleep, which is in line with the two stage model of sleep and memory by Smith et al. (2004).The self and the world during dreaming differ. The perceived world during waking depends on making sense of external sensory input, which engenders a strong sense of external reality in which the ‘self and its inner-world’ exists. Self-organizing during waking and dreaming enables integration of the self and the world in both states. It is noteworthy, that within this research topic so many novel themes have emerged and new questions and speculations have been posed with regards to relations among unusual sleep experiences – specifically lucid dreaming -, dissociation, psychosis, and memory. It brings together a richness of research by combining fields that originally have worked in isolation from each other. (shrink)

The will as first mover created in Francisco Suárez: The aim of this paper is to show that Francisco Suarez’s claim that the will is the prime mover of the human actions is grounded in his own metaphysical system. For that purpose, I argue that the will is not necessitated to act by any extrinsic efficient cause: nor by God’s grace, neither by the intellect, the law or fate. For all these active principles are either just a necessary condition for (...) the will’s act or something that necessitates the practical act of the intellect by which it guides the will, but does not affects the will itself. On the other hand, I argue that Suárez’s account on potency and act allows conceiving an efficient cause that is able to determine itself. Besides Suárez distinction between the transcendental sense of potency and act and the predicamental one –among which only the latter is relevant for this matte—, for him act does not perfect potency. Then the will can simultaneously be denominated patient and agent regarding its own action since it does not imply that the will can give itself something it previously lacked. (shrink)

In recent years, Swedish women belonging to a post-migrant generation have made their voices against racism and social inequality prominent within public debate. Engaging in segregated and economically deprived suburbs, these women make use of art in order to counter stereotypical narratives of themselves and their communities. Based on interviews from two research projects, Accessing Utopia and Gendered Islamophobia in Sweden, this article aims to understand the complexities in using art to protest racist structures and stereotypes. In what ways are (...) the young women making room for their own creative expressions in Swedish society, while countering processes of othering? How does the work of representation affect them? What meaning do the women give to the platforms and networks they have been involved in? This article shows that the women’s early experiences of othering and meeting likeminded youths play a central role in order to either enter or create collective platforms where they can creatively engage in expressing their subjectivities and counter society’s controlling images. Projects and platforms such as Revolution Poetry and Swedish hijabis provided collective self-care through support and confidence building among youths from marginalized communities. These platforms can be seen as an artistic homeplace for the interlocutors. The article also shows that the work of representation is sometimes felt as limiting. The activism the women engage in is a deeply personal struggle for self-valuation and seeking ways to live a life on one’s own terms. (shrink)

Elsewhere I have argued that particular degrees of imagination and consciousness, a cog­nitive process that I call reflective imagination, distinguish humans from other species and make possible, and underlie, the artistic experience. I take the artistic experience to be the universal and characteristically human capacity to experience oneself or others in a story by means of music, dance, song, pantomime, drawing, pretend play, or spoken or written language. In this paper I reconstruct the developmental path of the reflective imagina­tion via (...) the artistic experience in five stages: infancy, childhood, adolescence, adulthood, and senescence, and its plausible evolutionary trajectory from Australopithecines to Homo sapiens. Drawing upon both evolutionary and developmental theory, I conclude that the reflective imagination via the artistic experience has fulfilled, and still fulfills, important functions by activating memory systems, regulating emotional expression, promoting mutuality, training attentional focus, developing motor control, enabling prediction, free­ing from actuality, sourcing identity, complexifying consciousness, and affording behav­ioral adaptation.

By giving sympathy a central role, Adam Smith’s Theory of Moral Sentiments (1759) can be regarded as one of the ‘enlightened’ moral theories of the Enlightenment, insofar as it widened the scope of moral consideration beyond the traditionally restricted boundary of human beings. This, although the author himself does not seem to have been aware of this fact. In this paper, I want to focus on two aspects which I think lead to this conclusion. First, by making sentience the requisite (...) to be taken into moral consideration, nonhuman animals in Smith’s moral theory can count as moral patients towards whom we should exercise the virtue of beneficence (if not justice). Secondly, Smith’s idea of morality as working in concentric circles –generating more stringent duties towards those closer to us– could explain and perhaps also justify our caring for some nonhuman animals, especially pets.

One of the most remarkable aspects of John Maynard Smith’s work was the fact that he devoted time both to doing science and to reflecting philosophically upon its methods and concepts. In this paper I offer a philosophical analysis of Maynard Smith’s approach to modelling phenotypic evolution in relation to three main themes. The first concerns the type of scientific understanding that ESS and optimality models give us. The second concerns the causal–historical aspect of stability analyses of adaptation. The third (...) concerns the concept of evolutionary stability itself. Taken together, these three themes comprise what I call the natural philosophy of adaptation. (shrink)

À partir de l’œuvre de Marie-Dominique Chenu sur la théologie du travail et de sa contribution à la revue Lumière et vie, cet article s’interroge sur les conditions de possibilité d’une telle démarche aujourd’hui et invite à en dessiner les contours. Plus que tout autre projet théologique, la théologie du travail doit à la fois s’enraciner dans une lecture des signes des temps, lecture difficile qui interroge les conditions d’exercice de l’activité humaine, les modes de sociabilité qui l’accompagne et son (...) impact sur la nature. Les enjeux climatiques et environnementaux invitent à privilégier une réflexion sur le travail comme soin, soin de chacun, de la société, de la nature, et à continuer d’engager une démarche ecclésiale de discernement social en commun. À cet égard, la revue Lumière et vie apparaît comme un laboratoire, qui a trouvé un écho dans les démarches des mouvements d’Action catholique. Avec des ressources moindres, mais des facilités plus grandes pour engager une conversation globale, il paraît utile de continuer dans cette direction, à même de soutenir une espérance pour notre monde commun.

The earliest formulation of the Higgs naturalness argument has been criticized on the grounds that it relies on a particular cutoff-based regularization scheme. One response to this criticism has been to circumvent the worry by reformulating the naturalness argument in terms of a renormalized, regulator-independent parametrization. An alternative response is to deny that regulator dependence poses a problem for the naturalness argument, because nature itself furnishes a particular, physically correct regulator for any effective field theory in the form of that (...) EFT’s physical cutoff, together with an associated set of bare parameters that constitute the unique physically preferred “fundamental parameters” of the EFT. Here, I argue that both lines of defense against the initial worry about regulator dependence are flawed. I argue that reformulation of the naturalness argument in terms of renormalized parameters simply trades dependence on a particular regularization scheme for dependence on a particular renormalization scheme, and that one or another form of scheme dependence afflicts all formulations of the Higgs naturalness argument. Concerning the second response, I argue that the grounds for suspending the principle of regularization or renormalization scheme independence in favor of a physically preferred parametrization are thin; the assumption of a physically preferred parametrization, whether in the form of bare “fundamental parameters” or renormalized “physical parameters,” constitutes a theoretical idle wheel in generating the confirmed predictions of established EFTs, which are invariably scheme-independent. I highlight certain features of the alternative understanding of EFTs, and the EFT-based approach to understanding the foundations of QFT, that emerges when one abandons the assumption of a physically preferred parametrization. I explain how this understanding departs from several dogmas concerning the mathematical formulation and physical interpretation of EFTs in high-energy physics. (shrink)

My aim in this article is to present the formation of poblaciones callampa in Chile during the second half of the twentieth century (especially between 1950 and 1970), as an expression of the right of necessity of thousands of homeless persons. I suggest that this social phenomenon is the germ of the consequent tomas de sitio (illegal encampments), where the requisites to take part were “to be poor, to have children, three sticks and a flag”. The individual right of necessity (...) is the foundation of the formal claims of politically organized groups looking for a permanent place to live that fulfilled minimal criteria of social justice. Although the argument is focused on the specific case of the Chilean callampas, I suggest that it may be applied to other cases of precarious, illegal settlements in Latin America and worldwide.

In his final lectures and writings, Fichte continued to assert that his philosophy opened up a new word, one that he still associated with Kantian thought, although the horizon of his thinking had changed since 1801. The essay reveals this second horizon, on which Fichte worked until the end of his life. It asserts the reality of an absolute being and the ideality of the world representing the outer appearance or the existence of an absolute being, a world that is (...) nothing more than knowledge, seeing, an image of being and the images that form life. With this theory Fichte takes an original position in the history of Western philosophy. In seinen letzten Vorlesungen und Schriften behauptet Fichte weiterhin, dass seine Philosophie eine neue Welt eröffnet, die er immer noch mit dem kantischen Denken in Verbindung setzt, obwohl sich sein Denkhorizont seit 1801 verändert hatte. Im Aufsatz wird dieser zweite Horizont dargestellt und wie Fichte ihn bis zum Ende seines Lebens ausgearbeitete. In ihm wird die Realität eines absoluten Seins und die Idealität der Welt angenommen, die die äußere Erscheinung oder die Existenz des absoluten Seins darstellt und nichts anderes als Wissen, Sehen, Bild des Seins und bildendes Leben sei. Durch diese Lehre nimmt Fichte eine eigentümliche Stellung in der Geschichte der abendländischen Philosophie ein. (shrink)

This article reflects on two contrasting intellectual profiles: the Argentinian university lecturer Ernesto Quesada and the Mexican intellectual José Vasconcelos, who visited Argentina in 1922. As we shall see, both define the University Reform in a contrasting way a few years after 1918. On the one hand, Quesada advocates conceiving the Reform as a key experience in order to make advances in the professionalisation of university teaching and research, autonomising these practices from politics. On the other hand, Vasconcelos resists disciplinary (...) specialisation and defends the construction of continental political leaderships, within the reformist movement, in line with the Mexican Revolution experience. Likewise, this article addresses certain points of contact between Vasconcelos and the Argentinian Ricardo Rojas who ideologically converge and also distance themselves from each other on their assessment of the Reform in the years that spanned the 1920s to 1930s.

Its objective was to analyze how girls and boys from the city of Córdoba of ages between 8 and 9, that belong to different socioeconomic levels, build discourse around gender norms. About the analysis, it is focused around discourses built by children that live in one of the poorest city areas. This work explains how girls and boys reproduce, in their discourses, schemes considered as “traditional” around gender definition. And, (...) basically, the way both, boys and girls, stress men’s body relevance and their ability to exert physical violence towards their definition of masculinity. (shrink)

La identificación aparece así, entre otras cosas, como un dejar atrás el sujeto protegido de la modernidad y un tomar la diferencia, la otridad, como el único camino para que el sí-mismo avance.

Pregnancy presents some interesting challenges for the philosophy of embodied cognition. Mother and fetus are generally considered to be passive during pregnancy, both individually and in their relation. In this paper, we use the enactive operational concepts of autonomy, agency, individuation, and participation to examine the relation between mother and fetus in utero. Based on biological, physiological, and phenomenological research, we explore the emergence of agentive capacities in embryo and fetus, as well as how maternal agency changes as pregnancy advances. (...) We show that qualitatively different kinds of agency have their beginnings already in utero, and to what extent fetal and maternal movement modulate affectivity and individuation in pregnancy. We thus propose that mother and fetus are both agents who participate in pregnancy. Pregnancy then emerges as a relational developmental organization that anchors and holds its developing participants. We end the paper with reflections on ethical implications of this proposal, and suggestions for future research. (shrink)

At Universitat Politècnica de València, Meridies, an internship programme that places engineering students in countries of Latin America, is one of the few opportunities the students have to explore the implications of being a professional in society in a different cultural and social context. This programme was analyzed using the capabilities approach as a frame of reference for examining the effects of the programme on eight student participants. The eight pro-public-good capabilities proposed by Melanie Walker were investigated through semi-structured interviews. (...) The internship is an environment in which students can put into practice the knowledge they have acquired in undergraduate studies and to find practical relevance in what they studied. Occasionally, this also entails a critical questioning of what they have learned, a greater awareness of the limits of the contents of their studies and of the way things were taught, and interest in less explored issues that are closely linked to social justice. However, tensions can arise between the pro-public-good oriented perspectives of this programme, and a more instrumental vision. One way to overcome these tensions is to foster consideration of reflexivity, that is, the dynamic relationship between technology and society. To do so, the programme must create space before and during the internship, and upon the return of the students, to discuss and collectively reflect upon their lived experience. Additionally, it ought to engage supervisors in this educational journey, both at the university and in the host institutions, and also involve socially committed organisations in this task.

El ensayo indaga sobre las formas en que algunas escrituras chilenas de la última década han producido la escena liminar del fin de los tiempos, del fin del mundo y sus postri-merías. Interesa preguntar sobre cómo estas ficciones imaginan la crisis actual desde los espacios disruptivos, movedizos y también “excepcionalizados” de los confines, y cómo producen, a través del género apocalíptico “enmascarado, cifrado”, otra ima-ginación del presente, una crítica política que, evidenciando la crisis del presente como crisis de la imaginación (...) del futuro, podría reconducir nuestra mirada sobre los límites de nuestro tiempo y las condiciones de su superación. El ensayo intenta, asimismo, pensar esas escrituras de manera situada, desde una enunciación también en crisis, que asume lo contemporáneo en un trance de caída y trasformación. (shrink)
