This Correspondence argues in response to Coolsaet et al. (2024) that there is an important role to play for stance-independent justice discussions that are not tied to specific social, political or critical perspectives. These can be valuable for climate research audiences, but also as a basis upon which to critically debate and research injustices.

Individuals of many animal species are said to have a personality. It has been shown that some individuals are bolder than other individuals of the same species, or more sociable or more aggressive. In this paper, we analyse what it means to say that an animal has a personality. We clarify what an animal personality is, that is, its ontology, and how different personality concepts relate to each other, and we examine how personality traits are identified in biological practice. Our (...) analysis shows that biologists often study specific personality traits, such as boldness, sociability or aggressiveness, rather than personalities in general. We claim that personality traits are best understood as dispositions and that they are operationally defined in terms of certain sets of behaviours, which are studied in specific experimental set-ups. Furthermore, we develop an integrative philosophical account that specifies and formalises three criteria for identifying personality traits, which are used in biological practice. For an individual animal to have a personality trait it must, first, behave differently than others. Second, these behavioural differences must be stable over a certain time, and third, they must be consistent in different contexts. (shrink)

Understanding the link between brain evolution and the evolution of distinctive features of modern human cognition is a fundamental challenge. A still unresolved question concerns the co-evolution of tool behavior (i.e., tool use or tool making) and language. The shared neurocognitive processes hypothesis suggests that the emergence of the combinatorial component of language skills within the frontal lobe/Broca's area made possible the complexification of tool-making skills. The importance of the frontal lobe/Broca's area in tool behavior is somewhat surprising with regard (...) to the literature on neuropsychology and cognitive neuroscience, which has instead stressed the critical role of the left inferior parietal lobe. Therefore, to be complete, any version of the shared neurocognitive processes hypothesis needs to integrate the potential interactions between the frontal lobe/Broca's area and the left inferior parietal lobe as well as their co-evolution at a phylogenetic level. Here, we sought to provide the first elements of answer through the use of the massive deployment framework, which posits that evolutionarily older brain areas are deployed in more cognitive functions (i.e., they are less specific). We focused on the left parietal cortex, and particularly the left areas PF, PGI, and anterior intraparietal (AIP), which are known to be involved in tool use, language, and motor control, respectively. The deployment of each brain area in different cognitive functions was measured by conducting a meta-analysis of neuroimaging studies. Our results confirmed the pattern of specificity for each brain area and also showed that the left area PGI was far less specific than the left areas PF and AIP. From these findings, we discuss the different evolutionary scenarios depicting the potential co-evolution of the combinatorial and generative components of language and tool behavior in our lineage.

In this study, we evaluate how individual virtues and inter-organizational management control systems influence buyer–supplier performance through relationship quality. Results from a sample of 232 firms confirm that virtues and IOMCS relate positively to relationship quality and performance, respectively. However, IOMCS lose their positive influence on relationship quality when considered along with virtues. That is, when both variables enter the regression model simultaneously, virtues win. This interesting finding has particular resonance at a time when research on ethics still needs to (...) reinforce its positive effects on the practice of management. (shrink)

In this article, Peter and Rowland explore the role of implicit statistical learning in syntactic development. It is often accepted that the processes observed in classic implicit learning or statistical learning experiments play an important role in the acquisition of natural language syntax. As Peter and Rowland point out, however, the results from neither research strand can be used to fully explain how children's syntax becomes adult‐like. They propose to address this shortcoming by using the structural priming paradigm.

Research using the intermodal preferential looking paradigm (IPLP) has consistently shown that English‐learning children aged 2 can associate transitive argument structure with causal events. However, studies using the same methodology investigating 2‐year‐old children’s knowledge of the conjoined agent intransitive and semantic role assignment have reported inconsistent findings. The aim of the present study was to establish at what age English‐learning children have verb‐general knowledge of both transitive and intransitive argument structure using a new method: the forced‐choice pointing paradigm. The results (...) suggest that young 2‐year‐olds can associate transitive structures with causal (or externally caused) events and can use transitive structure to assign agent and patient roles correctly. However, the children were unable to associate the conjoined agent intransitive with noncausal events until aged 3;4. The results confirm the pattern from previous IPLP studies and indicate that children may develop the ability to comprehend different aspects of argument structure at different ages. The implications for theories of language acquisition and the nature of the language acquisition mechanism are discussed. (shrink)

IntroductionConcussion is a growing public health concern. No uniformly established therapy exists; neurofeedback studies report treatment value. We use infralow frequency neuromodulation to remediate disabling neurological symptoms caused by traumatic brain injury and noted improved outcomes with a novel concussion protocol. Postconcussion symptoms and persistent postconcussion symptoms are designated timelines for protracted neurological complaints following TBI. We performed a retrospective study to explore effectiveness of ILF in PCS/PPCS and investigated the value of using this concussion protocol.MethodPatients with PCS/PPCS seen for (...) their first neurology office visit or received their first neurofeedback session between 1 August 2018 and 31 January 2021 were entered. Outcomes were compared following treatment as usual vs. TAU with ILF neurotherapy. The study cohort was limited to PPCS patients; the TAU+ILF group was restricted further to PPCS patients receiving at least 10 neurotherapy sessions. Within the TAU+ILF group, comparisons were made between those who trained at least 10 sessions using concussion protocol and those who trained for at least 10 sessions of ILF regardless of protocol.ResultsAmong our resultant PPCS cohort leading persistent neurological complaints were headache, memory impairment, and brain fog. PPCS patients in TAU+ILF+CP demonstrated greater net and percent improvement of symptoms compared to PPCS subjects in TAU. PPCS patients in TAU+ILF-CP trended toward significant symptom improvements compared to TAU, and TAU+ILF+CP trended toward greater efficacy than TAU+ILF-CP.ConclusionPPCS patients who received TAU+ILF+CP demonstrated significantly greater improvement as a group when compared to TAU. When used as an integrative modality to treatment as usual in managing patients with PPCS, ILF neuromodulation with use of concussion protocol provided significant symptom improvements. (shrink)

The aim of this paper is to explain why, while Charles Darwin was well recognized as a scientific leader of his time, Claude Bernard never really regarded Darwinism as a scientific theory. The lukewarm reception of Darwin at the Académie des Sciences of Paris and his nomination to a chair only after 8 years contrasts with his prominence, and Bernard’s attitude towards Darwin’s theory of species evolution belongs to this French context. Yet we argue that Bernard rejects the scientific value (...) of Darwinian principles mainly for epistemological reasons. Like Darwin, Bernard was interested in hereditary processes, and planned to conduct experiments on these processes that could lead to species transformation. But the potential creation of new forms of life would not vindicate Darwinism since biologists can only explain the origin of morphotypes and morphological laws by the means of untestable analogies. Because it can be the object neither of experiments nor of any empirical observation, phylogeny remains out of science’s scope. Around 1878 Bernard foresaw a new general physiology based on the study of protoplasm, which he saw as the agent of all basic living phenomena. We will analyze why Bernard regarded Darwinism as part of metaphysics, yet still referred to Darwinians in his latter works in 1878. Basically, the absence of a scientific reception of Darwinism in Bernard's work should not obscure its philosophical reception, which highlights the main principles of Bernard’s epistemology.

It has been well documented that children perceive robots as social, mental, and moral others. Studies on child-robot interaction may encourage this perception of robots, first, by using a Wizard of Oz set-up and, second, by having robots engage in self-description. However, much remains unknown about the effects of transparent teleoperation and self-description on children’s perception of, and relationship formation with a robot. To address this research gap initially, we conducted an experimental study with a 2 × 2 between-subject design (...) in which 168 children aged 7–10 interacted with a Nao robot once. Transparency about the teleoperation procedure decreased children’s perceptions of the robot’s autonomy and anthropomorphism. Self-description reduced the degree to which children perceived the robot as being similar to themselves. Transparent teleoperation and self-description affected neither children’s perceptions of the robot’s animacy and social presence nor their closeness to and trust in the robot. (shrink)

Nearly five centuries have elapsed since Apollonia von Freyberg departed from her convent in Mülhausen. Little is known about this Poor Clare nun who witnessed the dissolution of her conventual shelter in the midst of her community’s protracted financial struggles as well as spiritual conflict catalyzed by the emerging Reformation. It is fortuitous, however, that documents related to Apollonia are preserved at the National Gallery of Art in Washington, DC and at the Archives de Mulhouse, in Mulhouse, France. Among these (...) are letters written to and on behalf of Apollonia as well as a detailed church inventory in which Apollonia’s many donations to her convent are recorded.... (shrink)

Eye gaze is a ubiquitous cue in child–caregiver interactions, and infants are highly attentive to eye gaze from very early on. However, the question of why infants show gaze-sensitive behavior, and what role this sensitivity to gaze plays in their language development, is not yet well-understood. To gain a better understanding of the role of eye gaze in infants' language learning, we conducted a broad systematic review of the developmental literature for all studies that investigate the role of eye gaze (...) in infants' language development. Across 77 peer-reviewed articles containing data from typically developing human infants in the domain of language development, we identified two broad themes. The first tracked the effect of eye gaze on four developmental domains: vocabulary development, word–object mapping, object processing, and speech processing. Overall, there is considerable evidence that infants learn more about objects and are more likely to form word–object mappings in the presence of eye gaze cues, both of which are necessary for learning words. In addition, there is good evidence for longitudinal relationships between infants' gaze following abilities and later receptive and expressive vocabulary. However, many domains are understudied; further work is needed to decide whether gaze effects are specific to tasks, such as word–object mapping or whether they reflect a general learning enhancement mechanism. The second theme explored the reasons why eye gaze might be facilitative for learning, addressing the question of whether eye gaze is treated by infants as a specialized socio-cognitive cue. We concluded that the balance of evidence supports the idea that eye gaze facilitates infants' learning by enhancing their arousal, memory, and attentional capacities to a greater extent than other low-level attentional cues. However, as yet, there are too few studies that directly compare the effect of eye gaze cues and non-social, attentional cues for strong conclusions to be drawn. We also suggest that there might be a developmental effect, with eye gaze, over the course of the first 2 years of life, developing into a truly ostensive cue that enhances language learning across the board.

This article offers a descriptive and analytic view of the different stages leading to the constitution of a corpus that is representative of the issues of climate and energy justice. Overall, the corpus contains over five million words and gathers reports, newsletters and web-pages dealing with the most equitable ways of moving to a low-carbon future in the aim of limiting climate change. It can be divided into six sub-corpora, according to types of discourse communities, and methods of constitution. We (...) begin by presenting the small Do It Yourself (DIY) corpora which were used as a starting point. Three discourse communities were selected to observe possible variation in their treatment of the issue: Non-Governmental Organisations (NGOs), United-Nation institutions, and the Renewable Energy Sector (RES). The sources are selected according to author, date, keywords in title. Using the concordance Antconc and WMatrix software we test the reliability of the corpora for their thematic content, terminology and lexical unit classification. Our first results enable us to confirm variation between the discourse communities. The discrepancy in sizes and the time-consuming nature of the initial DIY corpus constitution lead us to use BootCat to extend them, using keywords from the corpora as seeds to retrieve and download webpages. We thus contrast a more traditional approach to corpus building to web-as-corpus data gathering methods. We compare the results found in the BootCat corpora to test if they are as specific as those in the DIY corpora. This enables us to draw conclusions on the possible uses and advantages of relatively small corpora for the study of specialised discourse. (shrink)

This paper traces the unspoken, implicit white racial logic of the brain disease model of addiction, which is based on seemingly universal, disembodied brains devoid of social or environmental influences. In the United States, this implicit white logic led to “context-free” neuroscience that made the social hierarchies of addiction and its consequences invisible to, and thus exacerbated by, national policies on opioids. The brain disease model of addiction was selectively deployed among the white middle-class population that had long accessed narcotics (...) and pharmaceutical treatments for narcotics disorders from biomedical clinics, as opposed to from illegal sources subject to law enforcement. In turn, new treatments for opioid addiction were racially marketed to the same white clientele to which newly patented opioid analgesics were marketed, tapping into a circumscribed but highly lucrative consumer base that has long benefited from a legally protected, racially segregated safe space for white narcotics consumption. The connecting thread for the contemporary white opioid “crisis,” therefore, is white race as a ghost variable in addiction neuroscience and in its pharmaceutical and biotechnological translation.

Caroline Franks Davis provides a clear, sensitive, and carefully argued assessment of the value of religious experiences as evidence for religious beliefs. Much more than an 'argument from religious experience', the inquiry systematically addresses underlying philosophical issues such as the role of interpretation in experience, the function of models and metaphors in religious language, and the way perceptual experiences in general are used as evidence for claims about the world. The author examines several arguments from religious experience and, using (...) contemporary and classic sources from the world religions, gives an account of the different types of experience. To meet sceptical challenges to religious experience, she draws extenisvely on psychological and sociological as well as philosophical and religious literature, probing deeply into the questions whether religious experiences are merely a matter of interpretation, whether there is irreducible conflict among religious experiences, and whether psychological and other reductionist explanations of religious experience are satisfactory. She concludes that religious experiences, like most experiences, are most effective as evidence within a cumulative style of argument which combines evidence from a wide range of sources. (shrink)

The production of complex sequences like music or speech requires the rapid and temporally precise production of events (e.g., notes and chords), often at fast rates. Memory retrieval in these circumstances may rely on the simultaneous activation of both the current event and the surrounding context (Lashley, 1951). We describe an extension to a model of incremental retrieval in sequence production (Palmer & Pfordresher, 2003) that incorporates this logic to predict overall error rates and speed—accuracy trade-offs, as well as types (...) of serial ordering errors. The model—assumes that retrieval of the current event is influenced by activations of surrounding events. Activations of surrounding events increase over time, such that both the accessibility of distant events and overall accuracy increases at slower production rates. The model's predictions were tested in an experiment in which pianists performed unfamiliar music at 8 different tempi. Model fits to speed—accuracy data and to serial ordering errors support model predictions. Parameter fits to individual data further suggest that working memory contributes to the retrieval of serial order and overall accuracy is influenced in addition by motor dexterity and domain-specific skill.

As more young people feel safe to outwardly identify as transgender or gender expansive (TGE), meaning that their gender identity does not align with the sex they were assigned at birth, an increasing number of youth who identify as TGE seek gender-affirming medical care (GAMC). GAMC raises a number of ethical questions, such as the capacity of a minor to assent or consent, the role of parents or legal guardians in decisions about treatment, and implications for equitable access to care (...) when differing parental or custodial viewpoints are present. These questions are further complicated by the difficulties in explaining the limits of long-term research in GAMC, with regard to the preservation of fertility, for example. We present two de-identified composite case studies to highlight dilemmas that may arise and offer recommendations to better support patient- and family-centered decision making for GAMC. These include employing a multidisciplinUniverary shared decision-making approach, disentangling informed consent and assent from chronological age, developing a consistent approach to the assessment of decisional capacity, and developing age-appropriate informational materials.

Beyond the eras a dialogue seems to have been established between Bruegel the Elder (1525-1569) and Antonin Artaud (1896-1948). The poet’s wonder at the « painting of the North », both realistic and emblematic, reveals his deepest ideal as an artist : painting, a « magical » operation, deploys a power of expression based on signs and no longer on words, which the theatre is also called upon to seize. The juxtaposition of Bruegel’s Triumph of Death and a famous drawing (...) by Artaud, Le Théâtre de la cruauté [The Theatre of Cruelty], highlights the striking convergences between the two artists. Through their pictorial works, both of them renew over the centuries the funerary and mythical symbolism of death, inherited from the macabre scenes of medieval paintings, but also from ancient times. Studying the references to theatrical iconography in Bruegel’s painting, where carnival and crudity of death reinforce each other, allows us to deepen the meaning of these resonances. For the two artists, form and poetic momentum meet so that representation, as a structure common to painting and theatre, fixes a moment of the world, while animating that moment to infinity, thanks to signs conceived as « true hieroglyphs » (Artaud), a problem that Michel Foucault associated with the strongest truth that the experience of madness carries.

BackgroundImplementation of recommendations from clinical practice guidelines is essential for evidence based clinical practice. However, the most effective methods of implementation are unclear. We conducted a national, cluster-randomised, blinded implementation trial to determine if midwife or doctor local implementation leaders are more effective in implementing a guideline for use of oral dextrose gel to treat hypoglycaemic babies on postnatal wards. To prevent any conscious or unconscious performance bias both the doctor and midwife local implementation leaders were kept unaware of the (...) trial. This paper reports the ethical dilemmas and practical challenges of ensuring clinicians remained unaware of their involvement in an implementation trial.MethodsWe sought approval from the National Health and Disability Ethics committee to keep clinicians unaware of the trial by waiving the standard requirement for locality approval usually required for each district health board. The ethics committee did not approve a waiver of consent but advised that we approach the chief executive of each district health board to ask for provisional locality approval. Ultimately it was necessary to seek ethics approval for three separate study designs to keep clinicians unaware of the trial.ResultsThe median time for chief executive approval was 16 days and for locality approval was 57 days. We completed 21 different locality approval forms for 27 hospitals.ConclusionsKeeping clinicians unaware of their involvement in a national implementation cluster-randomised trial is feasible. However, despite a national ethics committee, significant logistical challenges were time consuming and delayed trial completion. Co-ordination of the locality approval process would help facilitate multi-centre trials. (shrink)

Following the distinctions proposed by Gamson and Easton the complex phenomenon of political alienation among the young was empirically subdivided in several dimensions. Within the 'input'dimension of political alienation we distinguished between the ability to process information and the ability to participate. Within the 'output'dimension we distinguished between two referents of distrust, political actors and authorities on the one hand, and the political system on the other. We succeeded in constructing reliable scales for each of these dimensions which were then (...) used as dependent variables in regression models. When turning to the explanation of the phenomenon our attention was focused first and foremost on the cultural factors. This was amply rewarded. Some of the normative aspects of culture, namely 'presenteism' and 'dionysianism', have a significant influence on various dimensions of political alienation. The impact of cognitive aspects appears to be even more significant. This means that an effective policy to counter the rise of political alienation wilt have to cope with a phenomenon solidly embedded in contemporary culture. (shrink)

Humans can follow different social learning strategies, sometimes oriented toward the models’ characteristics. The goal of the present study was to explore which who-strategy is preferentially followed in the technological context based on the models’ psychological characteristics. We identified three potential who-strategies: Copy the pedagogue, copy the engineer, and copy the friend. We developed a closed-group micro-society paradigm in which participants had to build the highest possible towers. Participants began with an individual building phase. Then, they were gathered to discuss (...) the best solutions to increase tower height. After this discussion phase, they had to make a new building attempt, followed by another discussion phase, and so forth for a total of six building phases and five discussion rounds. This methodology allowed us to create an attraction score for each participant. We also assessed participants’ theory-of-mind skills, technical-reasoning skills, and prosocialness to predict participants’ attraction scores based on these measures. Results show that we learn from engineers because they are the most successful. Their attraction power is not immediate, but after they have been identified as attractors, their technique is copied irrespective of their pedagogy or friendliness. These findings open avenues for the study of the cognitive bases of human technological culture. (shrink)

Les principes de l’éthique médicale sont, pour l’essentiel, clairement définis. Néanmoins on ignore, pour une large part, dans quelle mesure ils sont l’objet d’une réappropriation normative par les acteurs et comment ils structurent les pratiques.

Celui-ci nous a permis de saisir les interprétations de l’éthique médicale émergeant des discours des soignants en psychiatrie et d’identifier sa nature. Nous en exposerons les (...) facettes en tentant d’abord de comprendre le sens conféré à l’exclusion de l’éthique du champ de leur pratique par certains médecins.

Nous montrerons enfin que cette éthique de l’action se conçoit comme une éthique que la philosophie morale décrirait comme particulariste. (shrink)

Domestic abuse is a worldwide public health issue with long‐term health and social consequences. Nurses play a key role in recognizing and responding to domestic abuse. Yet there is considerable evidence that their responses are often inappropriate and unhelpful, such as trivializing or ignoring the abuse. Empirical studies have identified several reasons why nurses' responses are sometimes wanting. These include organizational constraints, e.g. lack of time and privacy; and interpersonal factors such as fear of offending women and lack of confidence. (...) We propose, however, that these factors present only a partial explanation. Drawing on the work of Julia Kristeva, we suggest that alternative understandings may be derived through applying the concept of abjection. Abjection is a psychological defence against any threat (the abject) to the clean and proper self that results in rejection of the abject. Using examples from our own domestic abuse research, we contend that exposure of nurses to the horror of domestic abuse evokes a state of abjection. Domestic abuse (the abject) transgresses established social boundaries of clean and proper. Thus when exposed to patients' and clients' experiences of it, some nurses subconsciously reject domestic abuse as a possibility (abjection). They do this to protect themselves from the horror of the act, but in so doing, render themselves unable to formulate appropriate responses. Rather than understanding the practice of some nurses as wilfully neglectful or ignorant, we argue that through a state of abjection, they are powerless to act. This does not refute existing evidence about nurses' responses to domestic abuse. Rather, as a relatively unknown concept in nursing, abjection provides an additional explanatory layer that accounts for why some nurses respond the way they do. Crucially, it elucidates the need for nurses to be supported emotionally when faced with the transgressive practice of abuse. (shrink)

Only a few studies explore the lifeworld of the spouses of persons affected by early-onset Alzheimer disease. The aim of this study is to explore the lifeworld of spouses when their partners are diagnosed with AD, focusing on spouses’ lived experience. The study employs an interpretative phenomenological framework. Ten in-depth interviews are performed. The results show that spouses’ lifeworld changes with the diagnosis. They experience an imprisoned existence in which added obligations, fear, and worry keep them trapped at home, both (...) physically and mentally. In their longing for freedom, new strategies and attitudes helps the spouses to create an extended “lived space” with their partner. The findings stress the importance of paying attention to the lifeworld of spouses and making clinical recommendations on this basis. Most importantly, the lifeworld perspective has implications for how we understand what care is. We hope to challenge all different healthcare professionals and invite them to discuss the deep meaning of care and the definition of being professional in encounters with vulnerable others from a lifeworld perspective.

Le critère d’absence d’envie, introduit par J. Tinbergen et utilisé par certaines théories de la justice distributive, ne permet pas, dans tous les cas, d’identifier des allocations de biens respectant l’exigence de pareto-optimalité. Pour cette raison il a été, durant un temps, délaissé. Néanmoins, ce critère demeure utile dans certains contextes dont nous voudrions préciser les caractéristiques. En effet, plusieurs travaux récents d’économie normative ont montré que, sous certaines conditions et même dans un contexte de production, l’absence d’envie offre une (...) solution à la recherche d’allocations équitables. Ainsi, nous voudrions examiner, à partir de ces résultats, sous quelles conditions le champ d’application du critère d’absence d’envie peut être étendu, en vue d’identifier des allocations équitables, dans un contexte économique d’échange comme de production.The non envy criterium, introduced by Tinbergen and convoqued by some theories of justice, cannot always be used to identify allocations which also satisfy the requirement of Pareto-optimality. This is the reason why it had been neglected for a while. Nevertheless, it is still useful in some contexts we would like to describe. In fact, recent conclusions of normative economy demonstrated that, in some conditions and even in the framework of production, this criterium provide a solution for fair allocations. Precisely, we would like, on the basis of these results, to determine which extent has the implementation of non envy criterium in order to identify fair distributive allocations in a context of exchange and production as well.

ABSTRACT This paper aims to illustrate the contribution of Acquisition Linguistics combined with the dialogic view driven by Bakhtin’s ideas, in order to describe morpho-syntactic acquisitions. According to the first approach, interaction is the main driver of syntactic acquisition processes, especially adults’ adjustments to the morpho-syntactic attempts of children and children’s repetitions of adults’ speech. In parallel, a dialogic approach to language acquisition focuses on how the two speakers’ co-construction of discourse leads children to use and acquire the linguistic ability (...) to share and construct meaning in discourse. We analyse conversations between adults and children aged between 2 and 4 years old, with typical and atypical developments. Our results show how inter-discursive facts in dialogue and repetition in interaction are major contributors of language acquisition processes. (shrink)
