Published: September 2024

AbstractThe cognitive deterioration of politicians is a critical emerging issue. As professions including law and medicine develop and implement cognitive assessments, their insights may inform the proper strategy within politics. The aging, lifetime-appointed judiciary raises legal and administrative questions of such assessments, while testing of older physicians experiencing cognitive decline provides real-life examples of implementation. In politics, cognitive assessment must contend with the field’s unique challenges, also taking context-dependent interpretations of cognitive-neuropsychological status into account. These perspectives, from legal and medical experts, political scientists, and officeholders, can contribute toward an equitable, functioning, and non-discriminatory system of assessing cognition that educates the public and enables politicians to maintain their public responsibilities. With proper implementation and sufficient public knowledge, we believe cognitive assessments for politicians, particularly political candidates, can be valuable for maintaining properly functioning governance. We offer recommendations on the development, implementation, and execution of such assessments, grappling with their democratic and legal implications.
The timing and mode of southern Andean human migrations
Authors: Barberena Ramiro , Becerra-Valdivia Lorena , Guevara Daniela , Novellino Paula 
Published: September 2024

Abstract
While recent genomic and isotopic information show that migration has been pervasive along human history, southern Andean archaeology has largely overlooked its importance in shaping human trajectories of sociocultural change. Building on previous isotopic research that identified the presence of migrant farmers in the Uspallata Valley (Mendoza, Argentina), we present chronological and bioarchaeological results that help to characterize the timing and mode of human migrations in the southern Andes. The burials with migrants show the representation of the different age classes, including a high abundance of children, as well as both men and women, suggesting that family groups were likely involved. The Bayesian modeling of 16 direct dates for migrants indicates that these migrations started between 1210–1275 CE (median 1255 CE) and finished at 1320–1425 CE (median 1360 CE), indicating that there is nearly no overlap between the commencement of this migration phase and the southwards expansion of the Inka Empire. The model defines a diachronic process that lasted between 55 and 195 years, implying that migration to Uspallata was a multi-generational process that involved between two and eight generations (median of four generations). Our contextual, bioarchaeological and chronological evidence indicates that the conditions fostering migration to Uspallata were sustained through time, inviting to explore persisting push-pull dynamics acting during this period. 87Sr/86Sr results show that migration occurred across the daily territories of these groups and may have involved movement across social or ethnic frontiers.
VIRTUE'S CLAIM TO FAME (STATIUS, THEBAID 10.610–80)

AbstractThis note argues that the appearance of Virtus at the outset of Menoeceus’ sacrifice in Statius’ Thebaid (10.610–80) is modelled on Virgil's Fama (Aen. 4.173–97).
FRAMING THE DELPHIC ORACLE, INSTITUTIONALIZING THE OLYMPIC GAMES: PHLEGON OF TRALLES’ OLYMPIADS
Authors: Guo Zilong 
Published: September 2024

AbstractThis article re-examines the account of the Delphic oracle in Phlegon of Tralles’ Olympiads (FGrHist 257 F 1). It argues that the oracular utterance is framed in an attempt to bolster the Lycurgan institution of the Olympic Games in 776 b.c. More specifically, according to Goffman's theory, the divine anger of Zeus (mênis) is keyed to the modulation of the frame, or the cognitive perspective, that has been radically changed by warfare and plague in the Peloponnese, thus serving a heuristic function in achieving political rationality. By showing the Delphic oracle to be even more dynamic than previous scholarship has suggested, frame analysis increases knowledge and understanding of the literary, social and political progresses reported in ancient sources.
ANTHOLOGIA PALATINA 8 AS A HELLENISTIC BOOK OF POEMS: STRUCTURE AND MEANING IN GREGORY OF NAZIANZUS
Authors: Prieto Domínguez Óscar 
Published: September 2024

AbstractThis article analyses Anth. Pal. 8 as a Hellenistic book of poems, i.e. as a collection artfully arranged by an author-editor and not as a mere gathering of sepulchral epigrams devoid of any reflection or literary aspiration. In common with modern poetry books, Anth. Pal. 8 was conceived for linear sequential reading. A close study of its tripartite structure, of the thoughtful collocation of each piece and of their organizing principles in well-thought-out sequences reveals the ultimate eschatological meaning of the book. Finally, a comparative contextualization with other late antique poets indicates a late antique dating for the elaboration of this collection as such, whereas the strong numerological element and the religious transcendence sought by the distribution of the poems point to Gregory of Nazianzus himself as the author-editor of Anth. Pal. 8.

Published: September 2024

Abstract
Hybridization of parasitic species is an emerging health problem in the evolutionary profile of infectious disease, particularly within trematodes of the genus Schistosoma. Because the consequences of this hybridization are still relatively unknown, further studies are needed to clarify the epidemiology of the disease and the biology of hybrid schistosomes. In this article, we provide a detailed review of published results on schistosome hybrids of the haematobium group. Using a mapping approach, this review describes studies that have investigated hybridization in human (S. haematobium, S. guineensis, and S. intercalatum) and animal (S. bovis and S. curassoni) schistosome species in West Africa (Niger, Mali, Senegal, Côte d’Ivoire, Benin, Nigeria) and in Central Africa (Cameroon, Gabon, Democratic Republic of Congo), as well as their limitations linked to the underestimation of their distribution in Africa. This review provides information on studies that have highlighted hybrid species of the haematobium group and the regions where they have been found, notably in West and Central Africa.
Obituary: Eve Caroline Southward (née Judges) 1930–2023

Published: September 2024

Abstract
Eve Caroline Southward (1930–2023) was a multi-talented scientist, motivated by her curiosity and love of nature. Since she was never paid as a scientist, Eve was an amateur, in the best sense of the word. She was highly proficient at transmission electron microscopy and made lasting contributions to polychaete taxonomy, morphology and ecology. Eve was internationally respected, especially for her studies on the Siboglinidae, mouthless and gutless tubeworms (formerly called Pogonophora) that are found worldwide in the deep-sea. She described how the siboglinids obtained nutrition from symbiotic, sulphur-oxidising bacteria and described similar symbiotic relationships in several bivalve species. Eve wrote over 140 scientific publications and described 56 new benthic species, 47 being mouthless and gutless ‘pogonophores’. Eve assisted her husband Alan Southward in starting broad-scale intertidal surveys around the British Isles and Northwest Europe. These surveys formed the foundation for the time-series, later continued by others, that allowed assessments of the influence of climatic fluctuations, using intertidal rocky shore biota as indicators. Eve contributed, with Alan, to what became a 50-year study describing the long-term effects on intertidal communities of the oil pollution and excessive dispersant use resulting from the Torrey Canyon oil spill in 1967. Eve also co-wrote the Linnaean Society Synopsis on Echinoderms of the British Isles and helped complete unpublished work by Alan Southward and others on barnacle taxonomy.
Robust motion planning for mobile robots under attacks against obstacle localization

Published: September 2024

AbstractThanks to its real-time computation efficiency, deep reinforcement learning (DRL) has been widely applied in motion planning for mobile robots. In DRL-based methods, a DRL model computes an action for a robot based on the states of its surrounding obstacles, including other robots that may communicate with it. These methods always assume that the environment is attack-free and the obtained obstacles’ states are reliable. However, in the real world, a robot may suffer from obstacle localization attacks (OLAs), such as sensor attacks, communication attacks, and remote-control attacks, which cause the robot to retrieve inaccurate positions of the surrounding obstacles. In this paper, we propose a robust motion planning method ObsGAN-DRL, integrating a generative adversarial network (GAN) into DRL models to mitigate OLAs in the environment. First, ObsGAN-DRL learns a generator based on the GAN model to compute the approximation of obstacles’ accurate positions in benign and attack scenarios. Therefore, no detectors are required for ObsGAN-DRL. Second, by using the approximation positions of the surrounding obstacles, ObsGAN-DRL can leverage the state-of-the-art DRL methods to compute collision-free motion commands (e.g., velocity) efficiently. Comprehensive experiments show that ObsGAN-DRL can mitigate OLAs effectively and guarantee safety. We also demonstrate the generalization of ObsGAN-DRL.
A pixel-level grasp detection method based on Efficient Grasp Aware Network
Authors: Xi Haonan , Li Shaodong , Liu Xi 
Published: September 2024

AbstractThis work proposes a novel grasp detection method, the Efficient Grasp Aware Network (EGA-Net), for robotic visual grasp detection. Our method obtains semantic information for grasping through feature extraction. It efficiently obtains feature channel weights related to grasping tasks through the constructed ECA-ResNet module, which can smooth the network’s learning. Meanwhile, we use concatenation to obtain low-level features with rich spatial information. Our method inputs an RGB-D image and outputs the grasp poses and their quality score. The EGA-Net is trained and tested on the Cornell and Jacquard datasets, and we achieve 98.9% and 95.8% accuracy, respectively. The proposed method only takes 24 ms for real-time performance to process an RGB-D image. Moreover, our method achieved better results in the comparison experiment. In the real-world grasp experiments, we use a 6-degree of freedom (DOF) UR-5 robotic arm to demonstrate its robust grasping of unseen objects in various scenes. We also demonstrate that our model can successfully grasp different types of objects without any processing in advance. The experiment results validate our model’s exceptional robustness and generalization.
The Australian Music Students Health Survey: impact of past experience on student attitudes to health education
Authors: Ackermann Bronwen Jane , Wijsman Suzanne , Halaki Mark 
Published: September 2024

Abstract
Widespread research over four decades has shown that musicians suffer physical and psychological injuries that can begin during childhood and early adulthood. A survey of 268 Australian tertiary music students revealed their perceptions of the importance of health education as part of their education. While students rated health knowledge as highly important, they considered its inclusion in their education to be less significant. Thirty-six percent reported current physical pain or injury, and 41% reported current psychological health issues. Significant correlations emerged between students’ reported injury history and prioritisation of health education and particular health topics. This has implications for tertiary music education providers regarding policies for the integration of health education into the curriculum.
A corpus-based study on the “ungrammatical” aren't I
Authors: Xiang Mingyou , Jiang Xiao 
Published: September 2024

AbstractConcerning the “ungrammatical” interrogative form aren't I, many scholars have made their points. However, these scholars’ arguments are based on their personal observations and few studies have examined this phenomenon against large corpora. This study aimed at investigating the widespread usage of “ungrammatical” contraction form aren't I in question tags from both quantitative and qualitative perspectives. Based on large corpora, this study showed a clear picture of the current frequency of use of the question tags aren't I and other alternatives (amn't I, ain't I, am I not and an't I) in modern English. From a qualitative perspective, this study found that the reason why aren't I has taken hold as a recognized standard form around the globe lies in that the use of aren't I appears to be a smart coincidence to imply the potential double roles of “I” as both the addresser and the addressee in a monologue. In addition, the fact of the matter that amn't I is difficult to pronounce, am I not is bookish, an't I is old-fashioned and ain't I can only be used in informal situations, increases the popularity of aren't I. The findings of this study can justify the usage of “ungrammatical” aren't I as a natural norm in both British English and American English. These findings open new research avenues alongside pedagogical and sociolinguistic implications for other similar “ungrammatical” language phenomenon.
Local geometric properties of conductive transmission eigenfunctions and applications
Authors: Diao Huaian , Fei Xiaoxu , Liu Hongyu 
Published: September 2024

Abstract
The purpose of the paper is twofold. First, we show that partial-data transmission eigenfunctions associated with a conductive boundary condition vanish locally around a polyhedral or conic corner in

$\mathbb{R}^n$

,

$n=2,3$

. Second, we apply the spectral property to the geometrical inverse scattering problem of determining the shape as well as its boundary impedance parameter of a conductive scatterer, independent of its medium content, by a single far-field measurement. We establish several new unique recovery results. The results extend the relevant ones in [26] in two directions: first, we consider a more general geometric setup where both polyhedral and conic corners are investigated, whereas in [26] only polyhedral corners are concerned; second, we significantly relax the regularity assumptions in [26] which is particularly useful for the geometrical inverse problem mentioned above. We develop novel technical strategies to achieve these new results.

Summary
The Secretarybird Sagittarius serpentarius is a charismatic raptor of the grasslands and open savannas of Africa. Evidence of widespread declines across the continent has led to the assessment that the species is at risk of becoming extinct. Southern Africa was identified as a remaining stronghold for the species, but the status of this population requires reassessment. To determine the status of the species in South Africa, Lesotho, and Eswatini, we analysed data from a citizen science project, the Southern African Bird Atlas Project (SABAP). We implemented novel time-to-detection modelling, as well as summarisation of changes in reporting rates, using standard metrics, to determine the trajectory of the population. To cross-validate our findings, we used data from another citizen science project, the Coordinated Avifaunal Roadcounts (CAR) project. While our results were in agreement with previous studies that have reported significant declines when comparing SABAP1 (1987–1992) and SABAP2 (2007 and onwards), all analysis pathways that examined data within the SABAP2 period only, as well as CAR data from this period, failed to show an alarming declining trend over this more recent time period. We did, however, find some evidence for decreases in Secretarybird abundance in urban grid cells. We used random forest models to predict probability of occurrence, as well as probability of abundance (reporting rates) for the assessed region and provided population estimates based on these analysis pathways. Continued monitoring and conservation efforts are required to guard this population stronghold.
List packing number of bounded degree graphs

Published: September 2024

AbstractWe investigate the list packing number of a graph, the least
$k$
such that there are always
$k$
disjoint proper list-colourings whenever we have lists all of size
$k$
associated to the vertices. We are curious how the behaviour of the list packing number contrasts with that of the list chromatic number, particularly in the context of bounded degree graphs. The main question we pursue is whether every graph with maximum degree
$\Delta$
has list packing number at most
$\Delta +1$
. Our results highlight the subtleties of list packing and the barriers to, for example, pursuing a Brooks’-type theorem for the list packing number.

A quantitative general equilibrium approach to migration, remittances, and brain drain
Authors: Cespedes-Reynaga Nikita 
Published: September 2024

Abstract
The international migration literature has highlighted four key stylized facts from the perspective of the source country: (i) Migration rates are notably high, with some nations seeing over ten percent of their population living abroad. (ii) Certain developing countries have witnessed a significant exodus of skilled workers, commonly referred to as brain drain, spanning several decades. (iii) Migrants often maintain strong ties to their country of origin, evidenced by the substantial remittances they send back to their relatives. (iv) Migration is not necessarily permanent, as a considerable number of individuals return to their home country after a period spent abroad. In this paper, we present a theoretical model that endogenously explains these facts. Our model allows us to explore key issues in migration literature from a theoretical standpoint. We analyze the general equilibrium effects of migration, its long-term implications, and its welfare consequences. Additionally, we investigate whether the combined impact of return migration and remittances can counterbalance the effects of skilled migration. Finally, we evaluate the efficacy of policy interventions designed to mitigate the adverse effects of brain drain.
US trade policy and public health: heterogeneous effects from the North American Free Trade Agreement
Authors: Adu Derick T. , Sawadgo Wendiam P.M. , Li Wenying 
Published: September 2024

Abstract

Objective:
To investigate the causal link between the North American Free Trade Agreement (NAFTA) unrestricted sugar trade agreement signed in 2008 between the USA and Mexico and the diabetes prevalence across all fifty US states.

Design:
A quasi-experimental research design to investigate the causal effect of the NAFTA unrestricted sugar trade agreement on diabetes prevalence. Our study utilises a comprehensive panel dataset spanning from 2000 to 2016, comprising 1054 observations. To conduct our analysis, we applied both the difference-in-differences and event-study methodologies.

Setting:
All the states in the USA.

Participants:
The fifty states in the USA.

Results:
After the enactment of the NAFTA sugar trade agreement between the USA and Mexico in 2008, most states witnessed an increase in diabetes prevalence. The annual impacts displayed significant variation among states, with percentage increases spanning from 0·50 to 2·28 %.

Conclusions:
States with a higher percentage of their population living below the poverty line, a larger Black resident population and a lower proportion of high school graduates had more significant increases in diabetes prevalence attributed to the NAFTA sugar trade agreement.
‘Broken souls’ vs. ‘mad ax man’ – changes in the portrayal of depression and schizophrenia in the German media over 10 years
Authors: Sittner M. , Rechenberg T. , Speerforck S. , Angermeyer M.C , Schomerus G. 
Published: September 2024

Abstract

Aims
Population studies show the stigma of depression to diminish, while the stigma of schizophrenia increases. To find out whether this widening gap is reflected in the media portrayal of both disorders, this study compares the portrayal of depression and schizophrenia in German print media in 2010 vs. 2020.

Methods
We conducted a qualitative content analysis using a mixed deductive-inductive approach to establish a category system. In total, we analyzed 854 articles with the summative approach by Mayring.

Results
The study found a widening gap in the portrayal of schizophrenia and depression in German media between 2010 and 2020. Schizophrenia was depicted increasingly negative between 2010 and 2020, covering more negative stereotypes and focusing on its biological causes. Depression received increased attention and more neutral and professional coverage, with a greater emphasis on psychosocial causes and discussion of treatment options.

Conclusions
By showing a widening gap the study highlights how media may shape public views on mental illnesses and reflects public attitudes at the same time. Media analyses from other nations have shown similar trends. This emphasizes the need for responsible reporting to combat stigma and promote understanding worldwide. Therefore, the authors recommend a balanced coverage that includes accurate professional information about all mental illnesses.
This Drum Is Not the Devil’s Instrument: The Development and Performance of Drum Tunes in Norwegian Folk Music
Authors: MISTEREGGEN BIRGER , WAADELAND CARL HAAKON 
Published: September 2024

AbstractTrommeslåtter (drum tunes) have played a vital role in Norwegian traditional music for several hundred years. This article examines the development and performance of drum tunes in Norway, with a special focus on the work of Johannes Sundvor in transcribing drum music. We present several examples and analyse tunes from Sundvor’s collection. We also demonstrate how this Norwegian drum tradition is related to a tradition of European military drumming. The article concludes with a discussion of aspects of interpretation and an outline of the status of drum tunes today.
