The global nutrition community faces an urgent imperative to address inequities in food security while promoting inclusive approaches to nutrition science and practice. The Nutrition Society of Australia’s 2024 Annual Scientific Meeting on ‘Food for All: Promoting Equity, Diversity, and Inclusion in Nutrition’ addressed this critical challenge through a 4-day programme of cutting-edge, multi-disciplinary research. The conference brought timely focus to key issues, including food access, cultural food practices, nutrition service accessibility, and inclusive research and education approaches. The conference featured public presentations, workshops, oral and poster sessions, symposia, and early career researcher sessions, and emphasised incorporating diverse perspectives while highlighting collaborative approaches to promoting equitable food systems. Coordinated efforts among researchers, healthcare providers, community organisations, industry partners and policymakers remain essential to advance inclusive nutrition practices and ensure equitable access to nutritious food for all populations.
This article examines why the late-industrializing Scandinavian countries of Denmark, Norway, and Sweden over the long nineteenth century developed civil societies and political parties with an ability to compromise. Based on comparisons with contemporary Prussia and within-case evidence, it traces the explanation to Scandinavia’s impartial state administrations, forged before the French Revolution and the era of modern mass politics and democracy. This emphasizes the importance of a penetrative bureaucracy in forging auspicious state-society relations and downplays the separate impact of peaceful agrarian reforms for Scandinavia’s stable democratization.
We present new unconstrained simulations and constrained experiments of a pair of pitching hydrofoils in a leader–follower in-line arrangement. Free-swimming simulations with matched pitching amplitudes show self-organisation into stable formations at a constant gap distance without any control. Over a wide range of phase synchronisation, amplitude and Lighthill number typical of biology, we discover that the stable gap distance scales with the actual wake wavelength of an isolated foil rather than the nominal wake wavelength. A scaling law for the actual wake wavelength is derived and shown to collapse data across a wide Reynolds number range of $200 \leqslant Re \leqslant 59\,000$. Additionally, vortex analysis uncovers that the leader’s wake wavelength-to-chord ratio, $\lambda /c$, is the key dimensionless variable to maximise the follower’s/collective efficiency. When $\lambda /c \approx 2$ it ensures that the follower’s leading edge suction force and the net force from a nearby vortex pair act in the direction with the foil’s motion thereby reducing the follower’s power. Moreover, in both simulations and experiments mismatched foil amplitudes are discovered to increase the efficiency of hydrofoil schools by 70 % while maintaining a stable formation without closed-loop control. This occurs by (i) increasing the stable gap distance between foils to push them into a high-efficiency zone and (ii) raising the level of efficiency in these zones. This study bridges the gap between constrained and unconstrained studies of in-line schooling by showing that constrained-foil measurements can map out the potential efficiency benefits of schooling. These findings can aid in the design of high-efficiency biorobot schools.
The crystal structure of anisomycin, C14H19NO4, has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density theory functional techniques. Anisomycin crystallizes in the space group P212121 (#19) with a = 5.80382(4), b = 8.58149(6), c = 28.63508(26) Å, V = 1,426.183(27) Å3, and Z = 4 at 298 K. The crystal structure consists of layers of anisomycin molecules parallel to the ab-plane. The molecules form zig-zag chains of N–H···O and O–H···N hydrogen bonds along the a-axis. The powder pattern has been submitted to the International Centre for Diffraction Data for inclusion in the Powder Diffraction File™ (PDF®).
We analyze generating functions for trees and for connected subgraphs on the complete graph, and identify a single scaling profile which applies for both generating functions in a critical window. Our motivation comes from the analysis of the finite-size scaling of lattice trees and lattice animals on a high-dimensional discrete torus, for which we conjecture that the identical profile applies in dimensions $d \ge 8$.
This empirical study explores three aspects of engagement (affective, behavioral, and cognitive) in language learning within an English as a Foreign Language context in Japan, examining their relationship with AI utilization. Previous research has demonstrated that motivation positively influences AI usage. This study expands on that by connecting motivation with engagement, where AI usage serves as an intermediary construct. A total of 174 students participated in the study. Throughout the semester, they were required to use Generative AI (GenAI) to receive feedback on their writing. To prevent overreliance or plagiarism, carefully crafted prompts were selected. Students were tasked with collaboratively constructing essays during the semester using GenAI. At the end of the semester, students completed a survey measuring their motivation and engagement. Structural Equation Modeling was employed to reaffirm the previous finding that motivation influences AI usage. The results showed that AI usage impacts all three aspects of engagement. Based on these findings, the study suggests the pedagogical feasibility of implementing GenAI in writing classes with proper teacher guidance. Rather than being a threat, the use of this technological tool complements the role of human teachers and supports learning engagement.
We describe the findings of cyclidans from the unpublished collection of the famous paleontologist B.I. Chernyshev (1888–1950) in the storage of the Academician F.N. Chernyshev Central Scientific Research Geological Survey Museum (CNIGR museum, St. Petersburg, Russia). These cyclidans were discovered by various researchers in the Carboniferous and Permian of the Urals. They are represented by the following taxa: Oonocarcinus uralicus new species, Uralocyclus feldmanni new species, Ambocyclus capidulum (Chernyshev, 1933), and Magnitocyclus (?) sp. indet. The discovery of the new species Oonocarcinus uralicus n. sp. greatly expands the geographic and stratigraphic interval of the genus Oonocarcinus Gemmellaro, 1890, previously known from the Middle Permian and Triassic. The discovery of Uralocyclus feldmanni n. sp. in the Mississippian deposits of the Chelyabinsk Oblast indicates a wide distribution of the genus Uralocyclus Mychko and Alekseev, 2018 in the Early Carboniferous, because Carboniferous representatives of this genus were previously known only from Ireland and England. The paper provides an up-to-date list of all known cyclidan occurrences and taxa in Russia.
Phenelzine sulfate crystallizes in the space group P21/c (#14) with a = 20.7418(15), b = 5.51507(5), c = 20.6038(11) Å, β = 109.5490(25)°, V = 2,221.06(9) Å3, and Z = 8 (Ẓ̣′ = 2) at 298 K. The crystal structure consists of supramolecular double layers of cations and anions parallel to the bc-plane. The inner portion of the layers consists of the charged parts of the cations and the anions, whereas the outer surfaces consist of phenyl rings, with van der Waals interactions between the layers. The sulfate anions stack along the c-axis. Each N–H acts as a donor to at least one sulfate O atom, and each O atom acts as an acceptor in at least one N–H···O hydrogen bond. The powder pattern has been submitted to the International Centre for Diffraction Data for inclusion in the Powder Diffraction File™ (PDF®).
The 2018 election cycle was referred to as a “Rainbow Wave” because of the record number of LGBTQ+ candidates seeking and winning elective office. The backlash toward the LGBTQ+ community during the first Trump administration, at the local and national level, invigorated queer candidates to run for office. Then, in 2020 and 2022, news headlines again called the election cycles a “Rainbow Wave” (Debussy 2020; Lavietes 2022). According to the Victory Institute, the 2024 election marked a 1.1% increase in LGBTQ+ candidates compared to 2020, however, it was also a 4.8% decrease compared to candidates in 2022. Further, among LGBTQ+ candidates, the share of lesbian candidates dropped nearly 10 percentage points, from 26.7% of all LGBTQ+ candidates in 2020 to only 16.1% in 2024. At the same time, the group of LGBTQ+ candidates in 2024 were the most racially diverse in history, with 37.6% being people of color and just over 15% not identifying as cisgender (LGBTQ+ Victory Fund 2024).
In one-dimensional Diophantine approximation, the Diophantine properties of a real number are characterized by its partial quotients, especially the growth of its large partial quotients. Notably, Kleinbock and Wadleigh [Proc. Amer. Math. Soc.146(5) (2018), 1833–1844] made a seminal contribution by linking the improvability of Dirichlet’s theorem to the growth of the product of consecutive partial quotients. In this paper, we extend the concept of Dirichlet non-improvable sets within the framework of shrinking target problems. Specifically, consider the dynamical system $([0,1), T)$ of continued fractions. Let $\{z_n\}_{n \ge 1}$ be a sequence of real numbers in $[0,1]$ and let $B> 1$. We determine the Hausdorff dimension of the following set: $ \{x\in [0,1):|T^nx-z_n||T^{n+1}x-Tz_n|<B^{-n}\text { infinitely often}\}. $
Political Equality is the view that, in political matters, everyone should have an equal say. Political Sufficiency is the view that, in political matters, everyone should have enough of a say. Whereas Political Equality is concerned with relativities, Political Sufficiency is a matter of absolutes. It is natural to assume that, to justify ‘one person, one vote’, we must appeal to Political Equality. We argue that this is not the case. If Political Equality justifies ‘one person, one vote’, so does Political Sufficiency. Moreover, there is reason to prefer Political Sufficiency to Political Equality.
At the 2024 US Democratic Convention, Kamala Harris presented her approach to the military in her speech accepting her historic nomination as the party’s candidate for the US presidency. In this essay, I reflect on the question: what would it mean if a woman of color led the American empire? I argue that scholars of gender, politics, and representation must turn their attention toward evaluating not just how gender conditions how politicians legislate, run their campaigns, or face barriers to winning office — but whether and to what extent politicians of any gender use their identities to combat the material suffering wrought by American imperialism. I echo calls for greater attention to power structures in the study of gender and representation (Brown et al. 2024) and argue that we must decenter “imperial feminism” and recenter tenets from Black and Third World feminism (Amos and Parmar 1984; Johnson-Odim 1991; Taylor 2017). To this end, I theorize a new type of representative that bridges these concerns: identity representatives.
In recent years, there has been growing interest in developing robots and autonomous systems that can interact with human in a more natural and intuitive way. One of the key challenges in achieving this goal is to enable these systems to manipulate objects and tools in a manner that is similar to that of humans. In this paper, we propose a novel approach for learning human-style manipulation skills by using adversarial motion priors, which we name HMAMP. The approach leverages adversarial networks to model the complex dynamics of tool and object manipulation and the aim of the manipulation task. The discriminator is trained using a combination of real-world data and simulation data executed by the agent, which is designed to train a policy that generates realistic motion trajectories that match the statistical properties of human motion. We evaluated HMAMP on one challenging manipulation task: hammering, and the results indicate that HMAMP is capable of learning human-style manipulation skills that outperform current baseline methods. Additionally, we demonstrate that HMAMP has potential for real-world applications by performing real robot arm hammering tasks. In general, HMAMP represents a significant step towards developing robots and autonomous systems that can interact with humans in a more natural and intuitive way, by learning to manipulate tools and objects in a manner similar to how humans do.
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.
