Anthuroid isopods in the genus Mesanthura (52 valid species) typically have a body with conspicuous dorsal pigmentation, with differences in the female pigmentation pattern being one of the main characters used to distinguish species. Five Mesanthura species have been reported to date from Japan. Here, we describe Mesanthura sol sp. nov. from Irabu Island and Okinawa main island, Okinawa, Japan, and illustrate its sexual dimorphism in colour pattern, with conspecificity between males and females confirmed with molecular data. We provide a description of Mesanthura miyakoensis based on specimens collected from Kochi, Shikoku, Japan. We present the first records of Mesanthura cinctula and Mesanthura nigrodorsalis, following their original descriptions. Finally, we provide partial sequences of the 16S rRNA gene for these four species and present a phylogenetic tree based on the sequences.

History is littered with unfulfilled promises that emerging technologies – from radios to televisions, and from computers to mobile phones – would completely transform teaching and learning. Now the same promises are being made of generative artificial intelligence (AI). This presentation argues that we should not be focusing on educational revolution, but instead on educational evolution. Education is a complex social, cultural, and political endeavour, serving multiple purposes and multiple stakeholders, and technology is just one of many elements in this large ecosystem.

Focusing on the context of language teaching and learning, this presentation discusses what has changed technologically, and suggests what could and should change educationally. It shows that ChatGPT and a range of other generative AI tools can contribute to language and literacy development in a number of ways, but that we need to be wary of their pedagogical, social, and environmental risks. Educators must develop the AI literacy necessary to take a more nuanced view of generative AI, and we must help our students to do the same.

This paper is based on a keynote presentation delivered at the English Australia Conference in Perth, Australia, on 12 September 2024, with some elaborations for the written version alongside minor updates to reflect more recent developments and publications.

This paper presents the development and implementation of a comprehensive system for acquiring telemetry from Alsat-2A and Alsat-2B satellites, whose orbits are phased 180 degrees apart, utilising the CDM600 demodulator. Integral to this system is an automatic learning module leveraging machine learning algorithms to optimise circular polarisation selection based on reception conditions. The software segment manages the demodulator, user interface, and coordinates the machine learning algorithm, drawing insights from historical polarisation data to construct predictive models for optimal polarisation selection. Through the integration of machine learning, this system aims to enhance telemetry signal reception quality, contributing to the success (Alsat-2A was launched on 12 July 2010, and Alsat-2B on 26 September 2016) of satellite missions.

Well-preserved specimens of the xanthid crab Lathahypossia aculeata (Busulini, Tessier, and Visentin, 1984) coming from middle Eocene volcanoclastites at Main quarry (Vicenza, Northeast Italy) are housed in three Museums in the Veneto region. Their exoskeletons, mainly chelipeds and thoracic sternum, are significantly encrusted by serpulid tubes assigned to the new species Propomatoceros lathahypossiae. Serpulids belong to the genus Propomatoceros, which has until now ranged from the Triassic to the Cretaceous; this record of the genus is the first in the Cenozoic. The abundance, frequency, and distribution pattern of the serpulid specimens on the different parts of the exoskeleton of the crabs were investigated, shedding light on the ecology/behavior of the encrusting species. Finally, the settlement and growth of serpulids related to sex, size, and molting cycle of the crabs were discussed, hypothesizing on the type of symbiotic relationship among the encrusters and their host.

Accacoeliid digeneans associated with fish of the family Molidae exhibit enigmatically high taxonomic diversity. However, the phylogenetic relationships between species within this digenean taxon are poorly understood. In the present study, the first nuclear 28S rRNA gene, ITS2 region of nuclear DNA, and mitochondrial cox1 gene sequence datasets were obtained for two members of the Accacoeliidae, a type and only species of the genus Odhnerium Yamaguti 1934 and an unidentified Accacladocoelium sp. collected from Mola mola (Linnaeus, 1758) off Iturup Island. Analyses of molecular differentiation and phylogenetic relationships indicate that Accacladocoelium sp. is a sister species to Accacladocoelium nigroflavum (Rudolphi, 1819). The genus Odhnerium is closely related to Tetrochetus Looss, 1912, on the 28S rRNA gene-based phylogenetic tree. Results of phylogenetic analysis based on both the mitochondrial cox1 gene and the concatenated ribosomal ITS2 region and cox1 gene of mtDNA show that the genus Odhnerium is close to the A. nigroflavum + Accacladocoelium sp. clade. In turn, the genus Accacladocoelium does not have monophyletic status in the trees reconstructed from these data.

Technical progress is considered a key element in the fight against climate change. It may take the form of technological breakthroughs, that is, shocks that induce significant leaps in the stock of knowledge. We use an endogenous growth framework with directed technical change to analyze the climate impact of such shocks. Two production subsectors coexist: one subsector is fossil-based, using a non-renewable resource, and yields carbon emissions; the other subsector uses a clean, renewable resource. At a given date, the economy benefits from an exogenous technology shock. We fully characterize the general equilibrium and analyze how the shock modifies the economy’s trajectory. The overall effect on carbon emissions basically depends on the substitutability between the production subsectors, the initial state of the economy, and the nature and size of the shock. We notably show that green technology shocks induce higher short-term carbon emissions when the two subsectors are gross complements, but also in numerous cases when they are gross substitutes.

Narratives and studies of Latino partisanship often emphasize Democratic identification, but some have recently suggested a shift towards Republicans. We address these by examining Latino party identification over a 34-year period, leveraging 35 national surveys with a total of over 103,000 Latino respondents along with Census data to create post-stratified survey weights to correct for biases. We emphasize changing partisanship over time by nativity, birth cohorts, and by national origin. From 2000 to 2012, we observed a slight overall increase in Democratic identification and a decrease in Republican identification, but this was driven by foreign-born Latinos. After 2012, we see declining Democratic identification overall, greater Republican identification among foreign-born and older native-born Latinos, and accelerating Independent identification among native-born Millennial and Gen Z Latinos. These results show that generational turnover and differences by nativity challenge extant theories of Latino partisan change over time.

The impact of synchronising the collection and supply of breast milk produced during the day and night on improving long-term health outcomes for preterm infants is discussed, focusing on breast milk as a valuable source of melatonin, an essential synchroniser of biological rhythms.

In 1979, the Maoist-inspired cultural movement Front Culturel Sénégalais (FCS) renewed interest in Lamine Senghor’s La Violation d’un pays (1927) through the underground republication of this pioneering work. Exploring the material history of La Violation d’un pays through the FCS’s repurposing of Senghor’s legacy as a key figure of interwar anti-imperialism during the long 1960s—when ongoing decolonization movements and youth protests fueled new forms of anti-imperialism—reveals transtemporal forms of anti-imperial solidarity and or: highlights the role of underground literary production in political struggle.

The Neotropical region is considered a biodiversity hotspot for reptiles, with eight families of terrestrial and freshwater chelonians. Parasites are of great importance to aquatic ecosystems and are essential to host communities. They help understand the patterns and phylogenetic relationships of their hosts and act to control populations. A literature survey on helminth parasites of chelonians in the Neotropical region was conducted, examining the most commonly found groups of helminths, the most parasitized hosts, compiling their biogeographical and political distribution and recording the parasite fauna of Phrynops geoffroanus in the state of Paraíba, northeastern Brazil. Considering the literature from 1850 to 2024, 202 helminth taxa were recorded. The Mesoamerican dominion had the highest number of helminth taxa, and Brazil was the political unit that recorded the most helminth taxa, followed by Mexico. Nematoda was the group with the highest number of taxa and occurred in all biogeographical units, with the species Spiroxys contortus being the most commonly found, followed by Trematoda, represented by the most commonly found species, Nematophila grandis. Hosts from the Chelidae family had the highest number of helminth taxa, followed by the Kinosternidae family. The most parasitized host species were Chelonoidis denticulatus and Phrynops hilarii. For the host Phrynops geoffroanus, the first occurrence of the nematode helminth Spiroxys contortus was recorded. This is the first study to include all parasitic helminths of terrestrial and freshwater chelonians in the Neotropical region, including a new occurrence in a chelonian host in the hinterland of Paraíba, Brazil.
