Neste artigo discutiremos o conceito de experiência [Erfahrung] em Walter Benjamin a partir de seus ensaios entre 1913 e 1936. Partiremos de seus escritos de militância juvenil a respeito da experiência com a intenção de identificarmos uma oposição entre figuras que reivindicam para si a experiência, a saber, o adulto, o que aconselha o jovem a desistir de si mesmo, e o jovem, que se encontra desorientado em razão dessa cisão entre gerações conflitantes, impossibilitando a continuidade da experiência, mesmo que (...) aqui seja compreendida de forma singular. Em seu ensaio sobre a experiência em Kant e nos neokantianos, a definição de experiência deve ser expandida, não deixando de alcançar o ato de contar histórias e de dar conselhos. Nos escritos de 30, consideraremos a abordagem da decadência da experiência (enquanto coletiva e perpassada por gerações), bem como a ascensão da vivência, que se trata de um vínculo isolado com as coisas em geral, restando formas privadas de lidar com a vida, causando desorientação no indivíduo isolado de sua comunidade real.

Esports, including virtual football, are a worldwide phenomenon. Yet, little is known about the physical activity levels of individuals engaged in virtual football game play. Therefore, we aimed to perform a preliminary evaluation of the levels of physical activity, sedentarism, and habits of physical training of adults engaged with virtual football in Portugal. This was a cross-sectional investigation based on a structured online survey using the International Physical Activity Questionnaire and a set of questions regarding habits of physical training. The (...) participants reported spending a median of 5,625 MET-min⋅week−1 being physically active. Still, the participants spent 320 min/day sitting, and 150 min/day practicing virtual football. According to the IPAQ scores, high physical activity levels were reported by 84.5% of the participants, and 87.1% were considered physically active considering the WHO guidelines on physical activity and sedentary behavior. Overall, 60.0% of the participants reported planning their own physical training. Maintaining or improving overall physical health was one of the main reasons for doing physical training, with only 6.1% responding being active to improve virtual football performance. Overall, the results showed that virtual football players accomplished the standard recommendations for physical activity, with high levels of physical activity, and encompassing regular physical training focused mostly on health promotion, rather than improved virtual football performance.

When the first edition of Pediatric Psychopharmacology published in 2002, it filled a void in child and adolescent psychiatry and quickly establishing itself as the definitive text-reference in pediatric psychopharmacology. While numerous short, clinically focused paperbacks have been published since then, no competitors with the scholarly breadth, depth, and luster of this volume have emerged. In the second edition, Christopher Kratochvil, MD, a highly respected expert in pediatric psychopharmacology, joins the outstanding editorial team led by Dr. Martin and Dr. (...) Scahill. In the new edition, the editors streamline the flow of information to reflect the growth in scientific data since the first edition appeared. The overall structure of the book remains the same, with major sections on underlying biology; somatic interventions; assessment and treatment; and special considerations. (shrink)

Peter John Olivi is oft characterized as having a particularly radical view, concerning the activity of the soul in cognition/appetite, where the soul’s cognitive and appetitive powers are the proper efficient causes from which even their most basic acts are produced; in contrast, external corporeal objects are insufficient to produce any direct effect on these “higher” powers. Olivi’s view can appear to be untenable, either leaving external objects completely outside of psychological explanation or requiring some novel type of cause outside (...) of the typical medieval-Aristotelian causal framework. However, in this paper, I seek to alleviate this concern by considering Olivi’s response that the object can still be considered a “broadly efficient cause”; in particular, I look at how Olivi’s same view is endorsed by Gonsalvus of Spain, one of Olivi’s students. I argue that Gonsalvus takes a more diplomatic approach, despite endorsing essentially the same view, which shows that their shared active view of cognition/appetite can safely fit into a wider medieval-Aristotelian causal framework with some further explanation. As I explain, this interpretation of Olivi, alongside Gonsalvus, helps put later active views of cognition/appetite (e.g., from John Duns Scotus), and their own qualifications, into a more complete context.

This article provides a critical and philosophical assessment of arguments invoked for and against the constitutional protection of commercial expression and the regulation of commercial speech with a focus on the commercialization of unhealthy food products.

Background: Although convolutional neural networks (CNNs) achieve high diagnostic accuracy for detecting Alzheimer’s disease (AD) dementia based on magnetic resonance imaging (MRI) scans, they are not yet applied in clinical routine. One important reason for this is a lack of model comprehensibility. Recently developed visualization methods for deriving CNN relevance maps may help to fill this gap as they allow the visualization of key input image features that drive the decision of the model. We investigated whether models with higher accuracy (...) also rely more on discriminative brain regions predefined by prior knowledge. Methods: We trained a CNN for the detection of AD in N = 663 T1-weighted MRI scans of patients with dementia and amnestic mild cognitive impairment (MCI) and verified the accuracy of the models via cross-validation and in three independent samples including in total N = 1655 cases. We evaluated the association of relevance scores and hippocampus volume to validate the clinical utility of this approach. To improve model comprehensibility, we implemented an interactive visualization of 3D CNN relevance maps, thereby allowing intuitive model inspection. Results: Across the three independent datasets, group separation showed high accuracy for AD dementia versus controls (AUC ≥ 0.91) and moderate accuracy for amnestic MCI versus controls (AUC ≈ 0.74). Relevance maps indicated that hippocampal atrophy was considered the most informative factor for AD detection, with additional contributions from atrophy in other cortical and subcortical regions. Relevance scores within the hippocampus were highly correlated with hippocampal volumes (Pearson’s r ≈ −0.86, p < 0.001). Conclusion: The relevance maps highlighted atrophy in regions that we had hypothesized a priori. This strengthens the comprehensibility of the CNN models, which were trained in a purely data-driven manner based on the scans and diagnosis labels. The high hippocampus relevance scores as well as the high performance achieved in independent samples support the validity of the CNN models in the detection of AD-related MRI abnormalities. The presented data-driven and hypothesis-free CNN modeling approach might provide a useful tool to automatically derive discriminative features for complex diagnostic tasks where clear clinical criteria are still missing, for instance for the differential diagnosis between various types of dementia.

The autosomal recessive genetic disorder, Nijmegen Breakage Syndrome, is characterised by an excessively high risk for the development of lymphatic tumours and an extreme sensitivity towards ionising radiation. The most likely explanation for these characteristics, a deficiency in the repair of DNA lesions, has been greatly substantiated by the recent cloning of the gene mutated in Nijmegen Breakage Syndrome patients and the analysis of its protein product, nibrin. The direct involvement of this protein in the processing of DNA double strand (...) breaks caused by ionising radiation and those also necessary for normal DNA metabolism can be correlated with many of the cellular and clinical aspects of the disease, including the cancer predisposition of patients and their heterozygous relatives.

What makes a human voice agreeable is a matter of scientific discussion. Whereas prosody was shown to play a role regarding “male-female” attraction, the impact of frequency modulations in “non-sexual”, notably commercial, contexts has attracted little attention. Another point unaddressed in the literature is auditory sensitivity to short-term frequency modulations as current studies focus more on sentence. Thirty French female operators were recorded over the phone. All “bonjour” greeting words were classified in terms of frequency modulation linearity and orientation at (...) the syllable and word levels. Then, the different voices were played back to students and seniors who had to rate each voice according to their degree of agreeableness. Listeners preferred non-monotonous voices. Differences between age-classes were greater than between sex-classes. Results suggest that short-term frequency changes are important for auditory evaluation of voice agreeableness. This study opens new research perspectives concerning the importance of prosody during consumer-seller interactions. (shrink)

In this paper, I aim to explain Peter John Olivi’s technical notion of “aspectus.” More specifically, I distinguish different uses of this notion by Olivi, not all of which have been made clear in the secondary literature, in order to help resolve a prima facie tension in the way Olivi puts together his active theory of cognition and his direct account of cognition (or “direct realism”). In brief, the issue is that Olivi builds his active theory of cognition out of (...) the commitment that the body cannot, strictly speaking, act as an efficient cause to produce an act of cognition in the spiritual soul; so, in order to account for soul-body interaction, Olivi will often speak of the soul having a seemingly one-way aspectus or orientation towards the body so that the soul can respond appropriately to changes in the body. However, given Olivi’s commitment to direct realism, the aspectus of cognition should go directly to the external object when, e.g., perceiving a present object. So, I take it Olivi must have some sort of distinction in mind between types of aspectūs in order to avoid contrariety. In short, my view is that by distinguishing between conscious/cognitive and non conscious/non-cognitive sorts of aspectūs in Olivi, one can understand how an aspectus towards inner corporeal changes can still contribute to direct cognition of external objects. Moreover, I take it that Olivi’s discussion of another technical notion, the mode of connection or “colligantia” between soul and body, provides further evidence for my interpretation. (shrink)

Meeting 5G high bandwidth rates, ultra-low latencies, and high reliabilities requires of network infrastructures that automatically increase/decrease the resources based on their customers’ demand. An autonomous and dynamic management of a 5G network infrastructure represents a challenge, as any solution must account for the radio access network, data plane traffic, wavelength allocation, network slicing, and network functions’ orchestration. Furthermore, federation among administrative domains (ADs) must be considered in the network management. Given the increased dynamicity of 5G networks, artificial intelligence/machine learning (...) (AI/ML) solutions are strong candidates able to learn, and take quick provisioning decisions upon fast changes in network conditions. Therefore, this chapter presents an analysis of the state-of-the-art solutions for 5G networks’ management, where AI/ML solutions are discussed and compared with traditional methods. Additionally, the chapter provides a technology overview of both standards, and existing solutions regarding the 5G network management, and directions toward the integration of AI/ML in 5G networks.

We prove that the standard cut is definable in each existentially closed model ofIΔ0+ exp by a (parameter free) П1–formula. This definition is optimal with respect to quantifier complexity and allows us to improve some previously known results on existentially closed models of fragments of arithmetic.

Preface de Pierre-Francois Moreau Beaucoup l'ont constate: il y a un air de famille entre spinozisme et psychanalyse. Meme remise en cause des attributs classiques de la subjectivite (libre-arbitre et transparence de la conscience a elle-meme); meme valorisation de l'affectivite du sujet (et notamment de la force de son desir); meme apprehension materialiste des phenomenes theologico-politiques (a travers l'analyse de la puissance de l'imaginaire); et dans une certaine mesure, meme visee therapeutique... Les deux grands noms de la psychanalyse, Freud et (...) Lacan, n'ont d'ailleurs pas cache, au moins a une certaine periode de leur parcours intellectuel, une proximite avec la pensee spinoziste. Soit. Mais ces grandes lignes de rapprochement entre psychanalyse et spinozisme permettent-elles autre chose que de dessiner une vague parente, dont il serait tout aussi aise, sinon plus, de souligner les lignes de fracture? Pour ne pas en rester a ce niveau de generalite, il est necessaire d'analyser precisement les notions, les problemes, les theses et les textes a travers lesquels cette confrontation entre spinozisme et psychanalyse prend sens et devient fructueuse. C'est le defi qu'entend relever le present recueil, le premier consacre a une telle confrontation. (shrink)

PurposeInformation and communications technologies (ICTs) have transformed the lives of many people around the world, yet billions remain unconnected. While many initiatives attempt to “connect the unconnected,” initiatives focused on access and skills-development alone will still fall short. Based on the authors’ experience with the SolarSPELL initiative, this study aims to propose using the concept of socio-technical awareness as a step forward in conceptualizing a more accurate picture of capabilities necessary to enable people to make meaningful use of the internet.Design/methodology/approachThis (...) paper uses an integrative literature review for the ideas related to the digital divide, digital inclusion and digital literacies, as well as the applied work of the authors in the SolarSPELL initiative, to develop the concept of socio-technical awareness, which is presented as a method for understanding empowered, meaningful internet use.FindingsThe argument is made that access, skills- and literacy-development are necessary but insufficient conditions for meaningful ICTs use. Accordingly, a third concept, socio-technical awareness, is introduced, and the case is made for including this concept in both application and measurement of meaningful use of ICTs.Practical implicationsThe design of digital inclusion initiatives should focus on increasing socio-technical awareness to empower users to make meaningful use of digital technologies.Originality/valueTaking a step further than most assessments of the digital divide or digital inclusion, this study proposes that to achieve meaningful internet use, people need access, requisite skills development and socio-technical awareness, to be able to make informed, empowered decisions about ICT use.

Most experimental studies of facial expression processing have used static stimuli (photographs), yet facial expressions in daily life are generally dynamic. In its original photographic format, the Karolinska Directed Emotional Faces (KDEF) has been frequently utilized. In the current study, we validate a dynamic version of this database, the KDEF-dyn. To this end, we applied animation between neutral and emotional expressions (happy, sad, angry, fearful, disgusted, and surprised; 1,033-ms unfolding) to 40 KDEF models, with morphing software. Ninety-six human observers categorized (...) the expressions of the resulting 240 video-clip stimuli, and automated face analysis assessed the evidence for 6 expressions and 20 facial action units (AUs) at 31 intensities. Low-level image properties (luminance, signal-to-noise ratio, etc.) and other purely perceptual factors (e.g., size, unfolding speed) were controlled. Human recognition performance (accuracy, efficiency, and confusions) patterns were consistent with prior research using static and other dynamic expressions. Automated assessment of expressions and AUs was sensitive to intensity manipulations. Significant correlations emerged between human observers’ categorization and automated classification. The KDEF-dyn database aims to provide a balance between experimental control and ecological validity for research on emotional facial expression processing. The stimuli and the validation data are available to the scientific community. (shrink)

Dans Logique du pire, Clément Rosset analyse une causalité conçue sans l’ombre d’une loi transcendantale, qui se fait par l’enchaînement des choses dans l’immanence actuelle. Rosset aperçoit cette causalité immanente dans la psychanalyse de Freud, non dans le concept lacanien du réel. Une telle conception de la causation recoupe celle du hasard, qui indique que les choses sont, tout simplement, sans raison d’être – ce en quoi consiste le tragique. Dans toute l’histoire de la philosophie, le philosophe qui a le (...) plus radicalement compris ce qu’est le hasard fut paradoxalement celui qui le définit comme nécessité absolue : Spinoza, « penseur tragique par excellence ». Nous énonçons et analysons les implications épistémiques et thérapeutiques qui découlent de cette compréhension. (shrink)

Let T be a second-order arithmetical theory, Λ a well-order, λ < Λ and X ⊆ ℕ. We use $[\lambda |X]_T^{\rm{\Lambda }}\varphi$ as a formalization of “φ is provable from T and an oracle for the set X, using ω-rules of nesting depth at most λ”.For a set of formulas Γ, define predicative oracle reflection for T over Γ ) to be the schema that asserts that, if X ⊆ ℕ, Λ is a well-order and φ ∈ Γ, then$$\forall \,\lambda (...) < {\rm{\Lambda }}\,.$$In particular, define predicative oracle consistency ) as Pred–O–RFN{0=1}.Our main result is as follows. Let ATR0 be the second-order theory of Arithmetical Transfinite Recursion, ${\rm{RCA}}_0^{\rm{*}}$ be Weakened Recursive Comprehension and ACA be Arithmetical Comprehension with Full Induction. Then,$${\rm{ATR}}_0 \equiv {\rm{RCA}}_0^{\rm{*}} + {\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - RFN}}\,_{{\bf{\Pi }}_2^1 } \left.$$We may even replace ${\rm{RCA}}_0^{\rm{*}}$ by the weaker ECA0, the second-order analogue of Elementary Arithmetic.Thus we characterize ATR0, a theory often considered to embody Predicative Reductionism, in terms of strong reflection and consistency principles.

IntroductionResearch on the impact of cancer on close relationships brings up conflicting results. This systematic review collects empirical evidence on the research questions whether a cancer diagnosis in general or the type of cancer affects the divorce rate.Materials and MethodsThis systematic review was conducted according to the guidelines of the Cochrane Collaboration and the PRISMA statement. The following electronic databases were searched: Web of Science, Ovid SP MEDLINE, PsycINFO, PsyINDEX, CINAHL, ERIC. Risk of bias assessment was performed with the preliminary (...) risk of bias for exposures tool template. The grading of methodological quality was assessed with the Newcastle-Ottawa Scale.ResultsOf 13,929 identified records, 15 were included in the qualitative synthesis. In 263,616 cancer patients and 3.4 million healthy individuals, we found that cancer is associated with a slightly decreased divorce rate, except for cervical cancer, which seems to be associated with an increased divorce rate.DiscussionAccording to this systematic review, cancer is associated with a tendency to a slightly decreased divorce rate. However, most of the included studies have methodologic weaknesses and an increased risk of bias. Further studies are needed. (shrink)
