The endemic Crow Honeyeater Eugymnomyza aubryana of New Caledonia is classified as “Critically Endangered”. Its rainforest habitat on mainland Grande Terre has been reduced by around 80% and the remaining habitat is highly fragmented. It is likely that by early 1900, anthropogenic changes had split the Crow Honeyeater’s distribution into two populations: one in the north of the island and one in the south separated by over 200 km. From 2011, the species was only known to be present in the south of Grande Terre with its distribution centred on the Blue River Provincial Park. It is essential for the species’ survival to protect its remaining natural habitat and its nests from predators.
The article focuses on the Ukrainian official language policies and their impact on Ukrainian people-building, claiming the state promotion of Ukrainian as an exclusive language of public life and the ethnically-based understanding of the Ukrainian people, inevitably lead to the exclusion of non-Ukrainian communities from participation in democratic processes, politicise the already problematic language situation and risk undermining the role of Ukrainian as an official language.
For such an analysis, and a conceptualisation of how the state can shape the nature of the people, the article proposes a new theoretical understanding of the people as an organisational system, based on a functional adaptation of Niklas Luhmann’s social systems theory and Charles Taylor’s social imaginary.
The Paragaricocrinidae is an enigmatic late Paleozoic family of camerate crinoids that retained a robustly constructed calyx more typical of Devonian to Early Mississippian crinoids. The discovery of the oldest member of this family, Tuscumbiacrinus madisonensis n. gen. n. sp., initiated a phylogenetic investigation of the Paragaricocrinidae and consideration of its diversification and paleobiogeographic distribution. Phylogenetic analyses demonstrate the need to describe Tuscumbiacrinus n. gen and conduct revisions to preexisting taxa, resulting in the description of Palenciacrinus mudaensis n. gen. n. sp.; Pulcheracrinus n. gen.; Nipponicrinus hashimotoi n. gen. n. sp.; and Nipponicrinus akiyoshiensis n. gen. n. sp. Megaliocrinus exotericus Strimple is reassigned to Pulcheracrinus n. gen. In addition to having an anachronistic morphology, relatively few specimens are known through the ca. 76-million-year duration of this family. This pattern is unlikely to have resulted from low fossil sampling alone, and instead likely reflects low abundance and/or taxonomic richness of a long-lived waning clade. From its apparent origination in Laurussia during the Mississippian, the Paragaricocrinidae diversified into a cosmopolitan clade. Following a diversity drop during the Pennsylvanian, the Paragaricocrinidae persisted but exemplified characteristics of a dead clade walking until its eventual extinction during the middle Permian (Wordian).
Herodotus’ depiction of Miltiades’ transgression in the sanctuary of Demeter Thesmophoros on Paros is marked by the intriguing phrase κινήσοντά τι τῶν ἀκινήτων (6.134.2). We examine this proverbial phrase, whose implications for Herodotus’ portrayal of Miltiades’ downfall have not yet been fully acknowledged. The article draws attention to the widespread concept of sacred immovables (ἀκίνητα) that were protected by imprecations, and suggests that Miltiades triggered a contingent curse protecting divine property. Herodotus configures the episode of Miltiades on Paros as a narrative of entrapment and steers his readers to view Miltiades’ fate as the consequence of a curse at work.
Let $K = \mathbf {R}$ or $\mathbf {C}$. An n-element subset A of K is a $B_h$-set if every element of K has at most one representation as the sum of h not necessarily distinct elements of A. Associated with the $B_h$-set $A = \{a_1,\ldots , a_n\}$ are the $B_h$-vectors $\mathbf {a} = (a_1,\ldots , a_n)$ in $K^n$. This article proves that “almost all” n-element subsets of K are $B_h$-sets in the sense that the set of all $B_h$-vectors is a dense open subset of $K^n$.
This study focuses on women’s hunger demonstrations and lootings in occupied Antwerp in May 1941. These actions were not just expressions of social discontent but also political actions in the form of illegal propaganda against the occupier. Through specific cases of demonstrations and looting, the first part of this article explores the pattern of these actions and the involvement of participants, local and German police and mayors. The second part provides a general picture of women’s demonstrations and lootings in Belgium and Antwerp, discussing the chronology and repression of these actions and the social profile of the participants. This article tells the story of resistance by working-class women, a perspective still largely absent from resistance historiography. It shows how an explicit female perspective allows us to write a history of female resistance.
This article centers on tsarist Russian officials’ understandings of and approaches to the Iranian Constitutional Revolution (1905–11). Although these officials relied on fragmental information and reflected internal discoordination in their dealings with Iran over the course of the revolution, a diachronic shift marked the policies they formulated in response. Although many of them attempted to navigate the Constitutional Revolution’s complexity in its early phases, they tended toward the use of force as unrest continued, culminating in the Russian invasion of northern Iran in December 1911. Uncritically confident in their exercise of power, Russian officials proceeded without considering alternative courses of action or the potential costs of military engagement in the revolution’s final stages. This heavy-handedness reflected continuity with the tsarist government’s crackdowns on socialists in the Caucasus after the Russian Revolution of 1905, and presaged its repressive, self-defeating responses to uprisings across the Russian Empire from 1912 to 1917.
In this research note, we propose a new typology of geographic places for use in advancing Canadian politics research on the political effects of place. We use hierarchical cluster analysis (HCA) to inductively derive place types from Aggregate Dissemination Areas (ADAs), a fine-grained unit of geography covering all of Canada, newly available from Statistics Canada. Using this approach, we uncover seven distinct place types, adding nuance to earlier more aggregated approaches focused on urban-rural (or urban-suburban-rural) distinctions. We then demonstrate our typology's utility by showing how it provides new insight into the relationship between place and politics, using the example of the 2021 Canadian federal election. We conclude with a discussion of how our approach may be used to further the study of Canadian political geography, and we make available all files necessary for researchers to merge our place types with survey data for this purpose.
According to an account that Felix Jacoby published as Philochoros (FGrH 328) F119, a gift of 30,000 medimnoi of grain was sent by Psammetichos from Egypt to Athens in the archonship of Lysimachides (445/4). When for its distribution a scrutiny (diapsēphisis) was held to check the citizen status of the claimants, 4,760 individuals appeared to be illegally listed as citizens, while 14,240 Athenians received a portion of grain. Brought together in this fragment, the events feature as a significant historical fact in studies of Pericles’ Citizenship Law, Athenian demography and the Athenian grain supply. However, in this article I argue that the account in F119 is not correct as it stands, but a conflation of historically disparate events into one episode. This confusing amalgam is not Philochoros’ mistake, but, with several possible causes, it must originate in the tradition between him and Plutarch, who incorporated it into his Life of Pericles (37). The most likely source of this conflated report for Plutarch’s version is the Alexandrian scholar Didymos. A major element in the confusion is the diapsēphisis of 346/5, when all male citizens scrutinized each other on their civic status, a one-off event that deeply affected Athenian society and its historical traditions.
The crystal structure of givinostat hydrochloride monohydrate Form I has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Givinostat hydrochloride monohydrate Form I crystallizes in the space group P21 (#4) with a = 7.98657(17), b = 8.20633(10), c = 18.2406(6) Å, β = 98.1069(13)°, V = 1,183.55(4) Å3, and Z = 2 at 298 K. The crystal structure consists of layers of cations and anions/water molecules parallel to the ab-plane. The cations stack along the a-axis, with the phenyl and naphthalene rings alternating in the stacks. Hydrogen bonds link the cations, anions, and water molecules in two-dimensional networks parallel to the ab-plane. The powder pattern has been submitted to the International Centre for Diffraction Data for inclusion in the Powder Diffraction File™ (PDF®).
We introduce a new class of heavy-tailed distributions for which any weighted average of independent and identically distributed random variables is larger than one such random variable in (usual) stochastic order. We show that many commonly used extremely heavy-tailed (i.e., infinite-mean) distributions, such as the Pareto, Fréchet, and Burr distributions, belong to this class. The established stochastic dominance relation can be further generalized to allow negatively dependent or non-identically distributed random variables. In particular, the weighted average of non-identically distributed random variables dominates their distribution mixtures in stochastic order.
Aerodynamic loads play a central role in many fluid dynamics applications, and we present a method for identifying the structures (or modes) in a flow that make dominant contributions to the time-varying aerodynamic loads in a flow. The method results from the combination of the force partitioning method (Menon & Mittal, 2021, J. Fluid Mech., vol. 907, A37) and modal decomposition techniques such as Reynolds decomposition, triple decomposition and proper orthogonal decomposition, and is applied here to three distinct flows – two-dimensional flows past a circular cylinder and an aerofoil, and the three-dimensional flow over a revolving rectangular wing. We show that the force partitioning method applied to modal decomposition of velocity fields results in complex, and difficult to interpret inter-modal interactions. We therefore propose and apply modal decomposition directly to the $Q$-field associated with these flows. The variable $Q$ is a nonlinear observable that is typically used to identify vortices in a flow, and we find that the direct decomposition of $Q$ leads to results that are more amenable to interpretation. We also demonstrate that this modal force partitioning can be extended to provide insights into the far-field aeroacoustic loading noise of these flows.
The crystal structure of ethynodiol diacetate has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Ethynodiol diacetate crystallizes in space group P21 (#4) with a = 17.4055(12), b = 7.25631(17), c = 19.6008(14) Å, β = 116.2471(23)°, V = 2,220.33(13) Å3, and Z = 4 at 298 K. The crystal structure consists of alternating layers of the two independent molecules parallel to the (101) plane. The molecules do not interact strongly with each other, as reflected by the low density of 1.150 g/cm3. The powder pattern has been submitted to the International Centre for Diffraction Data (ICDD) for inclusion in the Powder Diffraction File™ (PDF®).
In this study, we explore the evolution of instabilities in magneto-quasi-geostrophic (MQG) modons on the $f$-plane using a magnetohydrodynamic rotating shallow water model. The numerical experiments have been conducted using a recently proposed second-order flux-globalisation-based path-conservative central-upwind scheme. Our focus is on the evolution and interactions of three key configurations: singular, regular and hollow MQG modons, which represent cases where the magnetic field is confined within the separatrix, evenly distributed inside and outside the separatrix and localised outside the separatrix, respectively. The singular MQG modon emerges as the most stable configuration, demonstrating the greatest resilience to destabilising forces. A notable observation is its transition from a quadrupolar to a tripolar magnetic field structure before reverting to a quadrupole adjusted magnetic modon, accompanied by a clockwise rotation of the system. In terms of stability, singular modons are the most stable ones, while hollow modons are the least stable. As instabilities develop, southward or northward displacements become significantly more pronounced than eastward or westward movements, primarily due to the Coriolis force. Among the configurations, the hollow (singular) modons experience the biggest (smallest) displacements. Additionally, we investigate modon collisions and highlight three scenarios: interactions between cyclonic and anticyclonic components that form a composite modon with meridional bifurcation; collisions of cyclonic vortices that produce a tripolar structure with counterclockwise rotation; and collisions between anticyclonic components that result in a stable, quasi-stationary tripolar configuration. The resulting magnetic poles exhibit a checkered pattern, with their amplitude decreasing with increasing distance from the central vortex.
The notion of sound space emerges as a multifaceted exploration within the music, artistic and architectural realms, delving into its evolution from a musical object to a transdisciplinary aesthetic event. Rooted in the interplay of sound and space, the term defies strict definition, reflecting a dynamic amalgamation of interpretations throughout its historical practices and conceptualisations. This article engages with different perspectives on the subject of sound space, bringing together a group of architects, sound engineers, artists and researchers – all of them dedicated to sound – to discuss the sensitive experience of listening to space, within material, and/or dematerialised realities. The methodology was based on a series of interviews, confronting their different points of view, therefore building a compelling retrospective around the subject of study. In this exploration, sound space emerges as a complex entity that transcends traditional boundaries, offering a unique lens through which practitioners redefine architecture, challenge perceptions and engage in a dynamic interplay between sound, space and the listener’s experience. The resulting territory is depicted as a rhizomatic system with diverse temporalities coexisting and influencing the understanding of sound space within phenomenal and material perspectives. It portrays a dynamic and evolving system, celebrating diversity and interaction in a transdisciplinary field.
We study the class of composition operators acting on the Fréchet space $\mathrm {Hol}(\mathbb {B}_N)$ of all holomorphic maps on the unit ball of $\mathbb {C}^N$. We describe the conditions to make these operators continuous, invertible and compact. We also do the spectral study of these operators, depending on the nature of its symbol.
This study examines the Ionic frieze of the Parthenon, focussing on the concept of ‘Divinespace’ and ‘Mortalspace’ within its artistic composition. I examine how divinities and mortal figures are depicted in specifically designated spaces and how they intersect during the Panathenaic procession. Notably, two gods, Aphrodite and Hermes, are observed crossing into ‘Mortalspace’, identified by the two groups of athlothetai—officials responsible for the festival’s organization. The casual nature of their presence and the lack of awareness shown towards divine intrusions add depth to the understanding of ancient Greek religious art and rituals. By analysing votive reliefs from the Athenian Akropolis and by comparing them to the frieze, this research sheds light on the intricacies of the depiction and symbolism in this remarkable ancient artwork.
We show that the set of Julia limiting directions of a transcendental-type K-quasiregular mapping $f:\mathbb {R}^n\to \mathbb {R}^n$ must contain a component of a certain size, depending on the dimension n, the maximal dilatation K, and the order of growth of f. In particular, we show that if the order of growth is small enough, then every direction is a Julia limiting direction. We also show that if every component of the set of Julia limiting directions is a point, then f has infinite order. The main tool in proving these results is a new version of a Phragmén–Lindelöf principle for sub-F-extremals in sectors, where we allow for boundary growth of the form $O( \log |x| )$ instead of the previously considered $O(1)$ bound.
Jewish resistance to the destruction of European Jewry during the Nazi era has stirred many scholars; however, some areas of war-torn Europe remain neglected in this respect, for instance Italy and Italian-occupied territories. This article aims to unearth the Jewish history of Jewish resistance in the Italian province of Dalmatia between June 1941 and September 1943, emphasising longer evolution of political ideology, personal networks and social organisations that fostered and sustained resistance. Based on either as-yet unknown or rarely used testimonies of the Holocaust survivors who spent the war years in Dalmatia, this article argues that these are crucial to understand why and how Jewish politics in inter-war Yugoslavia enabled Jews to self-organise and to start and sustain open resistance to fascism.
