We derive effective Boussinesq and Korteweg–de Vries equations governing nonlinear wave propagation over a structured bathymetry using a three-scale homogenization approach. The model captures the anisotropic effects induced by the bathymetry, leading to significant modifications in soliton dynamics. Homogenized parameters, determined from elementary cell problems, reveal strong directional dependencies in wave speed and dispersion. Our results provide new insights into nonlinear wave propagation in structured shallow-water environments, and consequently motivate further fundamental and applied studies in wave hydrodynamics and coastal engineering.
Psychoanalysis deals with individual and collective trauma, in relation to the unconscious reproduction of what has caused a psychic breakthrough for the subject and the group, with each aftermath re-semantising painful past experiences. Archaic fears and defence mechanisms are common to everyone before giving way to more evolved modes of functioning. Confrontation with major traumatic experiences can undo the symbolic capacities acquired during human development and plunge the subject and the group into archaic modes of functioning: projection of the bad object outside the group, splitting between an all-good self-image and an all-bad image of the other, and denial of the suffering of the outside group. This regressive logic traps the actors in a victimisation likely to lead to further violence or to maintain a climate of permanent threat. Working on the dual recognition of trauma means that the experiences are not hidden, that the point of view of the other (whether inside or outside the group) is integrated and that a narrative of the past that leaves room for internal and external polyphony is passed on to future generations. This leads to the expression of internal conflict within oneself and one’s community, rejecting a monolithic vision of identity and history.
This introductory chapter presents and contextualises the main sources under study, and addresses the problems of a definition of consciousness. Given the vagueness of the notion, a working definition is proposed, which is based on cognitive model that uses three prototypical clinical presentations of impaired consciousness: delirium, sleep and fainting.
The Ghana–Togo border separates the Ewe people from their ritual spaces and objects. In Nyive, a border town divided into Ghana Nyive and Togo Nyive, these ritual spaces and objects are in Togo Nyive. The liminal space of the border complicates ritual practice by preventing community members from moving the ritual drum Aɖaʋatram (madness has led me astray) across the river and the international border. Nonetheless, communities in Nyive use ritual archives to maintain their identities in the context of colonial separation. They remake their identities through the symbolism, origin narrative, handling, and use of the drum Aɖaʋatram.
This chapter focuses on the intra-individual or ontogenetic level of analysis because its specificity allows us to draw the relationships, similarities, and differences between revisited genetic psychology and genetic social psychology, aiming to advance the understanding of social knowledge construction. The specificity of the genetic psychology developmental approach is to understand the conceptualization processes by which individuals reconstruct collectively constructed social knowledge while they appropriate it. We understand that the study of such mechanisms constitutes the main contribution of revisited genetic psychology to genetic social psychology. Finally, we analyze the design of didactic interventions to develop social knowledge, specifically for teaching controversial historical processes that conform to current intergroup relations and overcoming states of cognitive polyphasia.
Numerous infants are placed into care shortly after birth due to safeguarding concerns. This paper explores the themes and therapeutic needs of mothers who undergo the distressing experience of having their babies removed, leading to the development of complicated grief and trauma, and how maternal mental health services can support them. Drawing from existing literature, this paper identifies key therapeutic needs, including issues of identity, guilt, and shame, as well as feelings of isolation experienced by affected mothers. In the absence of specialised guidelines, this paper advocates for adaptions of existing evidence-based treatment modalities such as trauma-focused cognitive behavioural therapy, eye movement desensitisation and reprocessing, and narrative therapy. For each approach existing literature is utilised to discuss how these approaches can effectively address the unique needs of mothers affected by infant removals. This paper underscores the urgent need for robust evidence-based guidelines to guide maternal mental health services in effectively supporting mothers affected by infant removals. By highlighting the importance of appropriate timing for engagement, multi-disciplinary collaboration, and clear treatment recommendations, it aims to pave the way for a compassionate and effective approach to promoting the mental well-being of these mothers and fostering positive outcomes for both parent and child.
Key learning aims
(1) To understand the therapeutic needs of women who have experienced the removal of their babies at birth.
(2) To examine existing evidence regarding interventions for other types of loss and explore adaptions to support women who have experienced infant removal.
(3) To recognise the necessity for further research in developing recommendations for therapy interventions and enhancing the ability of maternal mental health services to effectively support these women.
People with disabilities in the US are now a health disparities population. Though 25% of US adults have a disability, only 5% of medical research grants are disability related. Knowledge about researchers’ perceived barriers to including people with disabilities in research has focused on a single disability/condition and thus has limited translational science applications. Our CTSA’s Disability as Difference: Reducing Researcher Roadblocks (D2/R3) project examined such roadblocks towards inclusion of people with intellectual and developmental disabilities (I/DD). I/DDs are broad, heterogeneous conditions that originate in childhood, have varying impact and function, and persist throughout the lifespan. Strategies that mitigate their under-representation in research will likely have general applicability to all disabilities. In D2/R3’s first phase we conducted semi-structured interviews with translational science and I/DD program leaders at ten US institutions about perceived barriers and facilitators to including people with I/DD in research. Interviews were held with 25 individuals from partnering Intellectual and Developmental Disabilities Research Centers, University Centers for Excellence in Developmental Disabilities, and Clinical and Translational Science Award programs. Collaborative thematic coding identified key themes as: attitudinal barriers (e.g., assumptions about consent capacity), logistical barriers (e.g., accommodation costs), health disparities, and generalizability concerns. Findings informed development of a survey based on Prosci’s ADKAR® model of change management’s five components: Awareness, Desire, Knowledge, Ability and Reinforcement. Exclusion appears to stem from researchers’ lack of awareness, misconceptions, and knowledge gaps rather than insurmountable obstacles.
Orthodox contractualists and rule consequentialists think that, for any action, the consequences of everyone performing that action determine whether that action is permissible. For them, “what if everyone did that?” is the fundamental moral question. By making “what if everyone did that?” the fundamental question of good moral reasoning, these moral theories can easily justify prohibitions on free-riding. But it also makes them face the ideal world problem. I argue that it was a mistake for moral theorists to generalize from an objection appropriate to cases of free-riding to all of morality. In short, we should understand the question “what if everyone did that?” to give expression to one, and only one, kind of objection to one’s action—namely, that, by performing that action, one would be making an exception of oneself. If we limit the scope of “what if everyone did that?” in this way, we can justify prohibitions on free-riding while avoiding the ideal world problem.
Silvennoinen (2025) analyzes the stored sequence going forward as an adverb that inherits adverb-class morphosyntax. This reply challenges that categorization on empirical grounds. The construction fails the key distributional test for adverbs: it cannot occur in integrated-medial position between subject and verb (*We going forward will prioritize replication), the diagnostic slot for core adverbs (We certainly will prioritize replication). Analysis of Silvennoinen’s corpus (n = 1,517) confirms this restriction – apparent ‘medial’ tokens prove either to be NP-internal modifiers or parenthetical supplements, never integrated clausal constituents. Instead, going forward patterns with PP adjuncts, occurring clause-initially, clause-finally, or as supplements. Internally, deverbal going heads the construction and licenses a directional complement forward(s), parallel to established deverbal prepositions like according [to …] and depending [on …]. The construction thus projects PP, not AdvP, aligning with The Cambridge Grammar of the English Language’s flexible-complement analysis of prepositions. This case demonstrates that storage and semantic specialization do not force categorical reanalysis.
This chapter presents sleep within a system of opposing tensions (consciousness-unconsciousness, health-disease), and in the midst of extra biological debates, particularly anthropological and sociological. Such tensions and debates illuminate how understanding sleep can be useful to apprehend ancient doctors’ ideas about the mental capacities that are compromised in impaired consciousness.
