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.
We give a new proof of the singular continuity of Minkowski’s $?$-function. Our proof follows by showing that the maximal Lyapunov exponent of a specific pair of $3\times 3$ nonnegative integer matrices related to Stern’s diatomic sequence is strictly greater than $\log 2$.
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.
We investigate flow instability produced by viscosity and density discontinuities at the interface separating two Newtonian fluids in generalised Couette–Poiseuille (GCP) flow. The base flow, driven by counter-moving plates and an inclined pressure gradient at angle $0^\circ \leqslant \phi \leqslant 90^\circ$, exhibits a twisted, two-component velocity profile across the layers, characterised by the Couette–Poiseuille magnitude parameter $0^\circ \leqslant \theta \leqslant 90^\circ$. Plane Couette–Poiseuille (PCP) flow at $ \phi = 0^\circ$ is considered as a special case. Flow/geometry parameters are $(\phi ,\theta )$, a Reynolds number $Re$ and the viscosity, depth and density ratios $(m,n,r)$, respectively. A mapping from the GCP to PCP extended Orr–Sommerfeld equations is found that simplifies the numerical study of interfacial-mode instabilities, including determination of shear-mode critical parameters. For interfacial modes, unstable regions in $(m,n,r)$ space are delineated by three distinct surfaces found via long-wave analysis, with the exception of strict Couette flow where the $(m,n)$ surface asymptotically vanishes with $\theta \rightarrow 0^\circ$. In interfacial stable regions but with unstable shear modes, one-layer PCP stability can be identified with a cut-off $\theta$ that conforms to canonical PCP stability. Competition between the interfacial-mode reversal phenomenon and the shear-mode cut-off behaviour is discussed. Extending to the full GCP configuration with the mapping algorithms applied, we systematically chart how pressure-gradient inclination and perturbation wavefront angle shift the balance between interfacial and shear instabilities in a specific case.
El comercio transpacífico entre América Latina y Asia Oriental durante el período previo a la Segunda Guerra Mundial ha sido escasamente estudiado. En este artículo, analizamos la construcción desde Argentina del vínculo mercantil con Japón entre 1934 y 1940. Al hacerlo, ponderamos las oportunidades y las limitaciones que surgieron en un contexto de des-globalización económica, y arrojamos luz sobre las posibilidades de diversificación geográfica del comercio exterior argentino. Abordando diversas fuentes de los sectores público y privado, el estudio revela que las iniciativas gubernamentales por profundizar los lazos con el socio oriental, apoyadas por los agroexportadores, enfrentó críticas de los empresarios textiles, quienes acusaron a Japón de ejercer dumping financiero y social.
Resource restrictions and changes to the ways in which psychiatrists are managed threaten professional autonomy and motivation. With examples from English National Health Service practice, maintaining knowledge and expertise, involvement in education and training, supporting research delivery and developing active followership skills represent transferable and realistic strategies that can improve psychiatrists’ autonomy wherever they work.
The Harnischia complex of the tribe Chironomini (Diptera: Chironomidae) comprises 20 genera. In the present study, we contribute to the taxonomic understanding of the genera Beckidia Sæther, Cryptochironomus Kieffer, and Cryptotendipes Beck and Beck of this complex in India. Our study employed an integrative taxonomic approach, incorporating morphological characteristics and molecular tools, to describe a new Cryptotendipes species. The genus Cryptotendipes, which comprises 26 species globally, is represented by five species in India, including the species that is newly described in the present study. In addition, we report new faunistic records for Beckidia hirsti (Freeman, 1957) and Cryptochironomus tamaichimori Sasa in Sasa and Kawai, 1987 for the first time from India.
Let $\gamma _{n}= O (\log ^{-c}n)$ and let $\nu $ be the infinite product measure whose nth marginal is Bernoulli $(1/2+\gamma _{n})$. We show that $c=1/2$ is the threshold, above which $\nu $-almost every point is simply Poisson generic in the sense of Peres and Weiss, and below which this can fail. This provides a range in which $\nu $ is singular with respect to the uniform product measure, but $\nu $-almost every point is simply Poisson generic.
Cette étude porte sur le changement linguistique en lien avec la référence temporelle au futur en français québécois du 21e siècle dans les données du Corpus de français parlé au Québec (CFPQ), qui couvrent la période 2006–2019. Trois variantes sont analysées: le présent du futur (PDF), le futur fléchi (FF) et le futur périphrastique (FP). Bien que plusieurs contraintes identifiées précédemment jouent un rôle semblable dans la variation (p. ex. la polarité, la présence de locutions adverbiales temporelles), la présente étude montre les taux les plus élevés de PDF en français québécois parmi les études antérieures consultées. Selon une interprétation en temps apparent, il y a une augmentation du PDF en contexte affirmatif et négatif qui n’est pas attribuable à un effet lexical. Ce résultat suggère que le PDF jouerait un rôle important dans le changement en cours par rapport à la référence temporelle au futur en français québécois.
Given $\beta>1$, let $T_\beta $ be the $\beta $-transformation on the unit circle $[0,1)$, defined by $T_\beta (x)=\beta x-\lfloor \beta x\rfloor $. For each $t\in [0,1)$, let $K_\beta (t)$ be the survivor set consisting of all $x\in [0,1)$ whose orbit $\{T^n_\beta (x): n\ge 0\}$ never enters the interval $[0,t)$. Kalle et al [Ergod. Th. & Dynam. Sys.40(9) (2020), 2482–2514] considered the case $\beta \in (1,2]$. They studied the set-valued bifurcation set $\mathscr {E}_\beta :=\{t\in [0,1): K_\beta (t')\ne K_\beta (t)~\text { for all } t'>t\}$ and proved that the Hausdorff dimension function $t\mapsto \dim _H K_\beta (t)$ is a non-increasing Devil’s staircase. In a previous paper [Ergod. Th. & Dynam. Sys.43(6) (2023), 1785–1828], we determined, for all $\beta \in (1,2]$, the critical value $\tau (\beta ):=\min \{t>0: \eta _\beta (t)=0\}$. The purpose of the present article is to extend these results to all $\beta>1$. In addition to calculating $\tau (\beta )$, we show that: (i) the function $\tau : \beta \mapsto \tau (\beta )$ is left-continuous on $(1,\infty )$ with right-hand limits everywhere, but has countably infinitely many discontinuities; (ii) $\tau $ has no downward jumps; and (iii) there exists an open set $O\subset (1,\infty )$, whose complement $(1,\infty )\setminus O$ has zero Hausdorff dimension, such that $\tau $ is real-analytic, strictly convex, and strictly decreasing on each connected component of O. We also prove several topological properties of the bifurcation set $\mathscr {E}_\beta $. The key to extending the results from $\beta \in (1,2]$ to all $\beta>1$ is an appropriate generalization of the Farey words that are used to parameterize the connected components of the set O. Some of the original proofs from the above-mentioned papers are simplified.
