description Publicationkeyboard_double_arrow_right Article , Other literature type 2019 France EnglishHumanities Commons SSHRCSSHRCAuthors: Lyall, Andrea; Nelson, Harry; Rosenblum, Daisy; Turin, Mark;Lyall, Andrea; Nelson, Harry; Rosenblum, Daisy; Turin, Mark;International audience; This paper describes the process and outcomes of a project focused on community centred reclamation of plant-based knowledge in the Kwak̓wala language from previously published materials as well as new documentation with Kwak̓wala speaking Elders. The paper describes our research process resulting in the documentation of 300 plant word names and phrases, starting with 135 plants with names and words in Kwak̓wala that had been documented between the late 19th and early 20th century by Franz Boas and George Hunt, subsequently added to and enriched by community members and academics. An audio-visual dictionary of these plant names and associated phrases is now available through the FirstVoices web portal (http://bit.ly/LDC_FirstVoices). The corresponding author initiated the work and then further developed the research in collaboration with Kwakwa̱ka̱’wakw fluent speakers, linguists, biologists, and the U’mista Cultural Society. The project has stimulated interest among community members who provided valuable feedback on the different ways in which this research can be further accessed and then delivered. The paper concludes with some structured reflections on how to proceed in community-led research projects such as this. The authors see further opportunity for continued cross-disciplinary and community-based research.

Alan eWallace; Risto eMiikkulainen; Clifford D Saron; Clifford D Saron;The capacity to focus one's attention for an extended period of time can be increased through training in contemplative practices. However, the cognitive processes engaged during meditation that support trait changes in cognition are not well characterized. We conducted a longitudinal wait-list controlled study of intensive meditation training. Retreat participants practiced focused attention (FA) meditation techniques for three months during an initial retreat. Wait-list participants later undertook formally identical training during a second retreat. Dense-array scalp-recorded electroencephalogram (EEG) data were collected during 6 min of mindfulness of breathing meditation at three assessment points during each retreat. Second-order blind source separation, along with a novel semi-automatic artifact removal tool (SMART), was used for data preprocessing. We observed replicable reductions in meditative state-related beta-band power bilaterally over anteriocentral and posterior scalp regions. In addition, individual alpha frequency (IAF) decreased across both retreats and in direct relation to the amount of meditative practice. These findings provide evidence for replicable longitudinal changes in brain oscillatory activity during meditation and increase our understanding of the cortical processes engaged during meditation that may support long-term improvements in cognition.

We examine an economy where professionals provide services to clients and where a professional can sell his practice to another. Professionals vary in quality, and clients in their need (or willingness-to-pay) for high-quality service. efficiency is measured as the number of matches between high-quality professionals and high-need clients. However, agent types are unobservable a priori. We find that trade in practices can facilitate the transmission of information about agent types; sometimes full efficiency is achieved. In cases where it is not, a tax on the sale of practices (based on the seller's age) can be used to achieve full efficiency. In addition, a ceiling on the price of services can be used to adjust the distribution of surplus between clients and professionals, while preserving efficiency.

Cette thèse a pour objectif de mieux comprendre pourquoi et comment se sont posés les enjeux normatifs de la reconnaissance publique dans la France des Lumières. Je montre que cette problématique prend toute son importance dans une période de transition vers la modernité où se conjuguent deux grands phénomènes. D’une part, les penseurs des Lumières, remettant en cause les formes révélées et arbitraires de l’autorité, font de la gloire un processus de reconnaissance du mérite susceptible d’ordonner une société harmonieuse et juste. D’autre part, le XVIIIe siècle voit l’émergence d’une culture de la célébrité qui favorise la multiplication des personnalités connues, en particulier issues du milieu des lettres et des arts de la capitale. Plutôt que de distinguer des individus dont le mérite et les accomplissements utiles suscitent l’admiration unanime, comme le voudrait l’économie de la gloire, la célébrité s’alimente, entre autres, de la controverse, du dévoilement de la vie privée et de la consommation du divertissement. Dès son avènement, elle est largement perçue comme un facteur de décadence morale et un symptôme d’appauvrissement culturel. Cette étude propose une incursion dans les discours moraux (traités de morale, observations sur les mœurs), esthétiques (palmarès allégoriques, ouvrages sur le goût) et biographiques (ana, almanachs satiriques) qui ont participé à l’élaboration, à la promotion et à la critique d’économies de la reconnaissance publique. En analysant une sélection de textes publiés sur une période d’environ 150 ans, entre la Querelle des Anciens et des Modernes et le premier tiers du XIXe siècle, je montre la cohérence de fond et les articulations de ces réflexions qui portent, en définitive, sur le genre d’ordre (littéraire, social ou politique) que l’on voudrait consolider ou voir advenir. Elles ouvrent en retour une perspective sur la spécificité de ce moment charnière, marqué entre autres par la déstructuration des hiérarchies traditionnelles et l’affirmation de l’individu comme sujet moral autonome. La thèse contribue à l’historicisation de la culture de la célébrité moderne en l’abordant par le biais des représentions et des luttes symboliques qu’elle suscite. Alors que la célébrité a été théorisée comme un phénomène médiatique qui instaure en particulier un rapport d’intimité à distance entre les personnes célèbres et le public, je montre qu’elle était largement interprétée à l’époque comme une dérégulation de l’économie affective de la gloire. Cette dernière repose sur une théorie du sentiment moral qui permet de reconnaître de manière naturelle le vrai mérite et de résoudre, avec le temps, la tension entre la relativité des opinions et l’objectivité des valeurs. La célébrité avive au contraire des passions, telles l’envie, l’ambition et la cupidité, qui poussent à fabriquer une reconnaissance immédiate et non méritée. Alors que s’affirme une compréhension systémique de ses mécanismes au sein d’une critique des mœurs de la société de l’élite parisienne, la célébrité se voit inscrite dans un ensemble cohérent de manifestations esthétiques et socioculturelles, incluant la mode, le luxe, le bel-esprit, le rococo, la satire, le persiflage, les lectures légères, les cabales et les spectacles. This dissertation examines how and why normative issues about public recognition developed in Enlightenment France. It shows that this question gained significance during the transitional period towards modernity as two important phenomena intersected. On the one hand, Enlightenment thinkers – who questioned the arbitrary foundations of authority – made glory into a process of recognition based on merit, which, in turn, could engender a harmonious and just society. On the other hand, the century saw the advent of a celebrity culture, which enabled the multiplication of famed individuals, especially emanating from the capital’s arts and literary circles. Instead of distinguishing individuals whose merit and useful accomplishments gave rise to unanimous admiration, as the economy of glory would demand, celebrity built upon things such as controversies, revelations about private lives, and the consumption of entertainment. From its inception, celebrity was perceived as a contributing factor to moral degeneracy and as a sign of cultural decay. This dissertation examines moral, aesthetic, and biographical texts that contributed to the creation, promotion, and critique of the economies of public recognition. An analysis of these texts published over a 150-year period – from the Querelle des Anciens et des Modernes to the first third of the nineteenth century – sheds light on their arguments with regards to the type of order (literary, social, or political) that they hoped to consolidate or engender. These texts offer a unique view into the particularities of this defining moment shaped by the elimination of traditional hierarchies and the advent of individuals as autonomous moral subjects. This dissertation historicises modern celebrity culture through an examination of its representations and of the conflicts it generated. Although celebrity has been theorized as a media phenomenon that creates a relationship of intimacy between famed individuals and the public, this study shows that, during the period in question, it was largely conceived as a deregulation of glory’s economy of feelings. This economy was based on a theory of moral sentiments that enabled the natural recognition of true merit, and that would, in due course, solve the tension between the subjectivity of opinions and the objectivity of values. To the contrary, celebrity fuelled passions – such as envy, ambition, and greed – which prompted the creation of immediate and undeserved renown. Celebrity was inscribed in a coherent set of aesthetic and sociocultural manifestations – including, fashion, rococo, bel esprit, satire, persiflage, light reading, cabals, and spectacles – while its systematic definition took shape through a critique of elite mores.

For further information contact us at helpdesk@openaire.eudescription Publication2023 EnglishHAL CCSD SSHRCSSHRCAuthors: Robineau, Colin;Robineau, Colin;International audience; In the Portuguese opinion press from 2010 to 2020, the question of Islamophobia appears in two forms: in discourses containing a discriminatory content against Muslims, and in discourses discussing the political uses of the term. While the first form is present in different degrees in all newspapers under study, the second form is mostly visible in the right-wing newspaper Observador, which criticises the political function, especially the intimidation (self-censorship) that the notion of Islamophobia fulfils. Following these findings, this chapter intend to observe how the term ‘Islamophobia’ is mobilised by Observador’s columnists in order to legitimise what they call a ‘rational critic’ of Islam, with no restraints regarding ‘political correctness’. Our main goal is to show how those columnists denounce the European political left and intellectuals of ‘sociologising’ the issue of Islamic fundamentalism and shaping a ‘political correctness’ that would compensate for their colonial guilt. To overcome this discursive impasse and liberate the violent speech on Islam, these journalists demand, on the one hand, the end of the ‘guilt-tripping’ of Europeans and, on the other, the end of Muslims’ ‘victimisation’.

Our decision to believe what another person says can be influenced by vocally expressed confidence in speech and by whether the speaker–listener are members of the same social group. The dynamic effects of these two information sources on neurocognitive processes that promote believability impressions from vocal cues are unclear. Here, English Canadian listeners were presented personal statements ( She has access to the building) produced in a confident or doubtful voice by speakers of their own dialect (in-group) or speakers from two different “out-groups” (regional or foreign-accented English). Participants rated how believable the speaker is for each statement and event-related potentials (ERPs) were analysed from utterance onset. Believability decisions were modulated by both the speaker’s vocal confidence level and their perceived in-group status. For in-group speakers, ERP effects revealed an early differentiation of vocally expressed confidence (i.e., N100, P200), highlighting the motivational significance of doubtful voices for drawing believability inferences. These early effects on vocal confidence perception were qualitatively different or absent when speakers had an accent; evaluating out-group voices was associated with increased demands on contextual integration and re-analysis of a non-native representation of believability (i.e., increased N400, late negativity response). Accent intelligibility and experience with particular out-group accents each influenced how vocal confidence was processed for out-group speakers. The N100 amplitude was sensitive to out-group attitudes and predicted actual believability decisions for certain out-group speakers. We propose a neurocognitive model in which vocal identity information (social categorization) dynamically influences how vocal expressions are decoded and used to derive social inferences during person perception.

Both novelty and uncertainty are potent features guiding exploration; however, they are often experimentally conflated, and an understanding of how they interact to regulate the balance between exploration and exploitation has proved elusive. Using a task designed to decouple the influence of novelty and uncertainty, we identify separable mechanisms through which exploration is directed. We show that uncertainty-directed exploration is sensitive to the prospective benefit offered by new information, whereas novelty-directed exploration is maintained regardless of its potential advantage. Using a computational framework in conjunction with fMRI, we show that uncertainty-directed choice is rooted in an adaptive bias indexing the prospective utility of exploration. In contrast, novelty persistently promotes exploration by optimistically inflating reward expectations while simultaneously dampening uncertainty signals. Our results identify separable neural substrates charged with balancing the explore/exploit trade-off to foster a manageable decomposition of an otherwise intractable problem.

These provide unprecedented accuracy across all tasks. However, the consistently overlooked downside of these models is their stunningly massive complexity, which seems concomitantly crucial to their success. In this paper, we address this issue by proposing a model pruning method based on the lottery ticket hypothesis. We modify the original approach to allow for explicitly removing parameters, through structured trimming of entire units, instead of simply masking individual weights. This leads to models which are effectively lighter in terms of size, memory and number of operations. We show that our proposal can remove up to 90% of the model parameters without loss of accuracy, leading to ultra-light deep MIR models. We confirm the surprising result that, at smaller compression ratios (removing up to 85% of a network), lighter models consistently outperform their heavier counterparts. We exhibit these results on a large array of MIR tasks including audio classification, pitch recognition, chord extraction, drum transcription and onset estimation. The resulting ultra-light deep learning models for MIR can run on CPU, and can even fit on embedded devices with minimal degradation of accuracy.

The paper describes our research process resulting in the documentation of 300 plant word names and phrases, starting with 135 plants with names and words in Kwak̓wala that had been documented between the late 19th and early 20th century by Franz Boas and George Hunt, subsequently added to and enriched by community members and academics. An audio-visual dictionary of these plant names and associated phrases is now available through the FirstVoices web portal (http://bit.ly/LDC_FirstVoices). The corresponding author initiated the work and then further developed the research in collaboration with Kwakwa̱ka̱’wakw fluent speakers, linguists, biologists, and the U’mista Cultural Society. The project has stimulated interest among community members who provided valuable feedback on the different ways in which this research can be further accessed and then delivered. The paper concludes with some structured reflections on how to proceed in community-led research projects such as this. The authors see further opportunity for continued cross-disciplinary and community-based research.

Alan eWallace; Risto eMiikkulainen; Clifford D Saron; Clifford D Saron;The capacity to focus one's attention for an extended period of time can be increased through training in contemplative practices. However, the cognitive processes engaged during meditation that support trait changes in cognition are not well characterized. We conducted a longitudinal wait-list controlled study of intensive meditation training. Retreat participants practiced focused attention (FA) meditation techniques for three months during an initial retreat. Wait-list participants later undertook formally identical training during a second retreat. Dense-array scalp-recorded electroencephalogram (EEG) data were collected during 6 min of mindfulness of breathing meditation at three assessment points during each retreat. Second-order blind source separation, along with a novel semi-automatic artifact removal tool (SMART), was used for data preprocessing. We observed replicable reductions in meditative state-related beta-band power bilaterally over anteriocentral and posterior scalp regions. In addition, individual alpha frequency (IAF) decreased across both retreats and in direct relation to the amount of meditative practice. These findings provide evidence for replicable longitudinal changes in brain oscillatory activity during meditation and increase our understanding of the cortical processes engaged during meditation that may support long-term improvements in cognition.

We examine an economy where professionals provide services to clients and where a professional can sell his practice to another. Professionals vary in quality, and clients in their need (or willingness-to-pay) for high-quality service. efficiency is measured as the number of matches between high-quality professionals and high-need clients. However, agent types are unobservable a priori. We find that trade in practices can facilitate the transmission of information about agent types; sometimes full efficiency is achieved. In cases where it is not, a tax on the sale of practices (based on the seller's age) can be used to achieve full efficiency. In addition, a ceiling on the price of services can be used to adjust the distribution of surplus between clients and professionals, while preserving efficiency.

Cette thèse a pour objectif de mieux comprendre pourquoi et comment se sont posés les enjeux normatifs de la reconnaissance publique dans la France des Lumières. Je montre que cette problématique prend toute son importance dans une période de transition vers la modernité où se conjuguent deux grands phénomènes. D’une part, les penseurs des Lumières, remettant en cause les formes révélées et arbitraires de l’autorité, font de la gloire un processus de reconnaissance du mérite susceptible d’ordonner une société harmonieuse et juste. D’autre part, le XVIIIe siècle voit l’émergence d’une culture de la célébrité qui favorise la multiplication des personnalités connues, en particulier issues du milieu des lettres et des arts de la capitale. Plutôt que de distinguer des individus dont le mérite et les accomplissements utiles suscitent l’admiration unanime, comme le voudrait l’économie de la gloire, la célébrité s’alimente, entre autres, de la controverse, du dévoilement de la vie privée et de la consommation du divertissement. Dès son avènement, elle est largement perçue comme un facteur de décadence morale et un symptôme d’appauvrissement culturel. Cette étude propose une incursion dans les discours moraux (traités de morale, observations sur les mœurs), esthétiques (palmarès allégoriques, ouvrages sur le goût) et biographiques (ana, almanachs satiriques) qui ont participé à l’élaboration, à la promotion et à la critique d’économies de la reconnaissance publique. En analysant une sélection de textes publiés sur une période d’environ 150 ans, entre la Querelle des Anciens et des Modernes et le premier tiers du XIXe siècle, je montre la cohérence de fond et les articulations de ces réflexions qui portent, en définitive, sur le genre d’ordre (littéraire, social ou politique) que l’on voudrait consolider ou voir advenir. Elles ouvrent en retour une perspective sur la spécificité de ce moment charnière, marqué entre autres par la déstructuration des hiérarchies traditionnelles et l’affirmation de l’individu comme sujet moral autonome. La thèse contribue à l’historicisation de la culture de la célébrité moderne en l’abordant par le biais des représentions et des luttes symboliques qu’elle suscite. Alors que la célébrité a été théorisée comme un phénomène médiatique qui instaure en particulier un rapport d’intimité à distance entre les personnes célèbres et le public, je montre qu’elle était largement interprétée à l’époque comme une dérégulation de l’économie affective de la gloire. Cette dernière repose sur une théorie du sentiment moral qui permet de reconnaître de manière naturelle le vrai mérite et de résoudre, avec le temps, la tension entre la relativité des opinions et l’objectivité des valeurs. La célébrité avive au contraire des passions, telles l’envie, l’ambition et la cupidité, qui poussent à fabriquer une reconnaissance immédiate et non méritée. Alors que s’affirme une compréhension systémique de ses mécanismes au sein d’une critique des mœurs de la société de l’élite parisienne, la célébrité se voit inscrite dans un ensemble cohérent de manifestations esthétiques et socioculturelles, incluant la mode, le luxe, le bel-esprit, le rococo, la satire, le persiflage, les lectures légères, les cabales et les spectacles. This dissertation examines how and why normative issues about public recognition developed in Enlightenment France. It shows that this question gained significance during the transitional period towards modernity as two important phenomena intersected. On the one hand, Enlightenment thinkers – who questioned the arbitrary foundations of authority – made glory into a process of recognition based on merit, which, in turn, could engender a harmonious and just society. On the other hand, the century saw the advent of a celebrity culture, which enabled the multiplication of famed individuals, especially emanating from the capital’s arts and literary circles. Instead of distinguishing individuals whose merit and useful accomplishments gave rise to unanimous admiration, as the economy of glory would demand, celebrity built upon things such as controversies, revelations about private lives, and the consumption of entertainment. From its inception, celebrity was perceived as a contributing factor to moral degeneracy and as a sign of cultural decay. This dissertation examines moral, aesthetic, and biographical texts that contributed to the creation, promotion, and critique of the economies of public recognition. An analysis of these texts published over a 150-year period – from the Querelle des Anciens et des Modernes to the first third of the nineteenth century – sheds light on their arguments with regards to the type of order (literary, social, or political) that they hoped to consolidate or engender. These texts offer a unique view into the particularities of this defining moment shaped by the elimination of traditional hierarchies and the advent of individuals as autonomous moral subjects. This dissertation historicises modern celebrity culture through an examination of its representations and of the conflicts it generated. Although celebrity has been theorized as a media phenomenon that creates a relationship of intimacy between famed individuals and the public, this study shows that, during the period in question, it was largely conceived as a deregulation of glory’s economy of feelings. This economy was based on a theory of moral sentiments that enabled the natural recognition of true merit, and that would, in due course, solve the tension between the subjectivity of opinions and the objectivity of values. To the contrary, celebrity fuelled passions – such as envy, ambition, and greed – which prompted the creation of immediate and undeserved renown. Celebrity was inscribed in a coherent set of aesthetic and sociocultural manifestations – including, fashion, rococo, bel esprit, satire, persiflage, light reading, cabals, and spectacles – while its systematic definition took shape through a critique of elite mores.

For further information contact us at helpdesk@openaire.eudescription Publication2023 EnglishHAL CCSD SSHRCSSHRCAuthors: Robineau, Colin;Robineau, Colin;International audience; In the Portuguese opinion press from 2010 to 2020, the question of Islamophobia appears in two forms: in discourses containing a discriminatory content against Muslims, and in discourses discussing the political uses of the term. While the first form is present in different degrees in all newspapers under study, the second form is mostly visible in the right-wing newspaper Observador, which criticises the political function, especially the intimidation (self-censorship) that the notion of Islamophobia fulfils. Following these findings, this chapter intend to observe how the term ‘Islamophobia’ is mobilised by Observador’s columnists in order to legitimise what they call a ‘rational critic’ of Islam, with no restraints regarding ‘political correctness’. Our main goal is to show how those columnists denounce the European political left and intellectuals of ‘sociologising’ the issue of Islamic fundamentalism and shaping a ‘political correctness’ that would compensate for their colonial guilt. To overcome this discursive impasse and liberate the violent speech on Islam, these journalists demand, on the one hand, the end of the ‘guilt-tripping’ of Europeans and, on the other, the end of Muslims’ ‘victimisation’.

Our decision to believe what another person says can be influenced by vocally expressed confidence in speech and by whether the speaker–listener are members of the same social group. The dynamic effects of these two information sources on neurocognitive processes that promote believability impressions from vocal cues are unclear. Here, English Canadian listeners were presented personal statements ( She has access to the building) produced in a confident or doubtful voice by speakers of their own dialect (in-group) or speakers from two different “out-groups” (regional or foreign-accented English). Participants rated how believable the speaker is for each statement and event-related potentials (ERPs) were analysed from utterance onset. Believability decisions were modulated by both the speaker’s vocal confidence level and their perceived in-group status. For in-group speakers, ERP effects revealed an early differentiation of vocally expressed confidence (i.e., N100, P200), highlighting the motivational significance of doubtful voices for drawing believability inferences. These early effects on vocal confidence perception were qualitatively different or absent when speakers had an accent; evaluating out-group voices was associated with increased demands on contextual integration and re-analysis of a non-native representation of believability (i.e., increased N400, late negativity response). Accent intelligibility and experience with particular out-group accents each influenced how vocal confidence was processed for out-group speakers. The N100 amplitude was sensitive to out-group attitudes and predicted actual believability decisions for certain out-group speakers. We propose a neurocognitive model in which vocal identity information (social categorization) dynamically influences how vocal expressions are decoded and used to derive social inferences during person perception.

Both novelty and uncertainty are potent features guiding exploration; however, they are often experimentally conflated, and an understanding of how they interact to regulate the balance between exploration and exploitation has proved elusive. Using a task designed to decouple the influence of novelty and uncertainty, we identify separable mechanisms through which exploration is directed. We show that uncertainty-directed exploration is sensitive to the prospective benefit offered by new information, whereas novelty-directed exploration is maintained regardless of its potential advantage. Using a computational framework in conjunction with fMRI, we show that uncertainty-directed choice is rooted in an adaptive bias indexing the prospective utility of exploration. In contrast, novelty persistently promotes exploration by optimistically inflating reward expectations while simultaneously dampening uncertainty signals. Our results identify separable neural substrates charged with balancing the explore/exploit trade-off to foster a manageable decomposition of an otherwise intractable problem.

These provide unprecedented accuracy across all tasks. However, the consistently overlooked downside of these models is their stunningly massive complexity, which seems concomitantly crucial to their success. In this paper, we address this issue by proposing a model pruning method based on the lottery ticket hypothesis. We modify the original approach to allow for explicitly removing parameters, through structured trimming of entire units, instead of simply masking individual weights. This leads to models which are effectively lighter in terms of size, memory and number of operations. We show that our proposal can remove up to 90% of the model parameters without loss of accuracy, leading to ultra-light deep MIR models. We confirm the surprising result that, at smaller compression ratios (removing up to 85% of a network), lighter models consistently outperform their heavier counterparts. We exhibit these results on a large array of MIR tasks including audio classification, pitch recognition, chord extraction, drum transcription and onset estimation. The resulting ultra-light deep learning models for MIR can run on CPU, and can even fit on embedded devices with minimal degradation of accuracy.
