Particles are accelerated to very high, non-thermal energies during explosive energy-release phenomena in space, solar, and astrophysical plasma environments. While it has been established that magnetic reconnection plays an important role in the dynamics of Earth’s magnetosphere, it remains unclear how magnetic reconnection can further explain particle acceleration to non-thermal energies. Here we review recent progress in our understanding of particle acceleration by magnetic reconnection in Earth’s magnetosphere. With improved resolutions, recent spacecraft missions have enabled detailed studies of particle acceleration at various structures such as the diffusion region, separatrix, jets, magnetic islands (flux ropes), and dipolarization front. With the guiding-center approximation of particle motion, many studies have discussed the relative importance of the parallel electric field as well as the Fermi and betatron effects. However, in order to fully understand the particle acceleration mechanism and further compare with particle acceleration in solar and astrophysical plasma environments, there is a need for further investigation of, for example, energy partition and the precise role of turbulence.
A Latent Hidden Markov Model for Process Data
Authors: Tang Xueying
Published: November 2023

Response process data from computer-based problem-solving items describe respondents’ problem-solving processes as sequences of actions. Such data provide a valuable source for understanding respondents’ problem-solving behaviors. Recently, data-driven feature extraction methods have been developed to compress the information in unstructured process data into relatively low-dimensional features. Although the extracted features can be used as covariates in regression or other models to understand respondents’ response behaviors, the results are often not easy to interpret since the relationship between the extracted features, and the original response process is often not explicitly defined. In this paper, we propose a statistical model for describing response processes and how they vary across respondents. The proposed model assumes a response process follows a hidden Markov model given the respondent’s latent traits. The structure of hidden Markov models resembles problem-solving processes, with the hidden states interpreted as problem-solving subtasks or stages. Incorporating the latent traits in hidden Markov models enables us to characterize the heterogeneity of response processes across respondents in a parsimonious and interpretable way. We demonstrate the performance of the proposed model through simulation experiments and case studies of PISA process data.

Published: November 2023

Honeybees are well-established bioindicators for different types of pollutants. This study aims to establish another species of the Apidae family as a bioindicator, with a distinct behaviour and life cycle. The bumblebee Bombus terrestris was used as a bioindicator for 12 metals. Bumblebee hives were placed at sampling sites in and around the city of Aachen, Germany, and metal concentrations were assessed using ICP-MS. Metal concentrations were compared to those found in honeybees described in the literature. Spatial differences in metal patterns were investigated by comparing two land-use types: urban and agrarian. Seasonal differences were compared by taking samples in spring and summer. All analysed metals were detected above the detection limit and within or even above the concentration range found in honeybees. Significant spatial differences were found for the metalloid B and the metal Cd with higher concentrations at the agrarian sites than the urban sites. Significant seasonal differences were found for 8 metals: Fe, Zn, Cu, Ni, Cd, and As concentrations were higher in summer than in spring, while B and V concentrations were higher in spring. To categorise the results, we applied the honeybee contamination index (HCI) and adapted it to bumblebee purposes. According to the HCI, only one agrarian site showed a high contamination level. This study shows that bumblebees are suitable bioindicators for metals. The obtained data can serve as a first baseline in the establishment of additional monitoring studies or risk assessments.

Published: November 2023

The Netherlands has a world-leading position in potato breeding, but little is known about the factors that led to this success. This paper analyses the factors that have influenced the development of potato breeding in the Netherlands. This study is based on research of the grey and scientific literature and interviews with various representatives from the Dutch potato breeding sector. We distinguish four periods: (i) Before 1888, no potato breeding in the Netherlands existed whereas in other countries first crosses occurred. (ii) 1888–1940, more individuals started breeding out of interest and hobby to overcome the commonly observed degeneration of potato. (iii) 1940–1967 the emergence of a corporate set up of breeding by private companies collaborating with small breeders. (iv) 1967–present, towards full-fledged breeding industry supported by the new Seeds and Planting Materials Act (ZPW) in 1967 including the breeders’ rights. Many factors including cultural practices, diseases, and market that determine the strategy of breeding have been analysed. The development is most of all ‘crop driven’ to maintain the level of production. But it was also ‘export driven’ leading to the development of an export-oriented seed potato sector. The conclusion is that three elements were dominant in the development of a strong potato breeding sector: (1) the broad cooperation among all players in the potato chain, (2) the design of the institutional infrastructure, and (3) the remuneration of the breeding work through legislation regarding plant breeders’ rights. The study ends with an outlook on future trends, one of them leading from an open to a more closed business culture.

Published: November 2023

At the beginning of the COVID-19 emergency, non-urgent surgical procedures had to be deferred, but also emergencies were reduced. To assess the global trend of pacemaker (PM) and implantable cardiac-defibrillator (ICD) procedures performed in Italy before, during, and after the first COVID-19 emergency, all the Italian hospital discharge records related to PM/ICD procedures performed between 2012 and 2021, sent to the National Institute of Health, were reviewed. Compared to 2019, in 2020, there was a reduction of first PM implants (52,216 to 43,962, −16%; p < 0.01), but not replacements (16,591 to 17,331, + 4%; p = 0.16). In particular, in April 2020, there was a drop of first implants (− 53,4% vs the average value of April 2018 and April 2019; p < 0.01), while the reduction of replacements was less evident (−32.6%; p = NS). In 2021, PM procedures increased to values similar to the pre-pandemic period. A reduction of ICD procedures was observed in 2020 (22,355, −7% toward 2019), mainly in April 2020 (− 46% vs April 2018/April 2019; p = 0.03). In 2021, the rate of ICD procedures increased (+ 14% toward 2020). A non-significant reduction of “urgent” procedures (complete atrioventricular block for PM and ventricular fibrillation for ICD), even in April 2020, was observed. In 2020, there was a reduction of first PM implants and ICDs, offset by increased activity in 2021. No decrease in PM replacements was observed, and the drop in “urgent” PM and ICD procedures was not statistically significant.
Early maladaptive schemas and perceived impact of COVID-19: the moderating role of sex and gambling
Authors: Estévez Ana , Macía Laura , Aonso-Diego Gema , Herrero Marta
Published: November 2023

Ample evidence indicates that early maladaptive schemas play an important role in the perceived impact of COVID-19 on individuals. Likewise, people with gambling disorder (GD), as well as women, show more maladaptive schemas than people without an addictive condition and men. However, no research to date has investigated the interrelationship between maladaptive schemas and the perceived impact of COVID-19, and even fewer studies have disaggregated the results by sex and clinical condition. This study aimed to examine the relationship between maladaptive schemas and the perceived impact of COVID-19 (i.e., emotional, physical, occupational, social, care, and quality of life). Second, we assessed the moderating role of sex and clinical group (i.e., gambling vs. non-gambling) on this relationship. A case-control study was performed with 160 participants, specifically 80 people with GD and 80 non-gamblers. The findings showed that individuals with greater maladaptive schemas showed higher COVID-19 impact. Moreover, gamblers presented higher maladaptive schemas and lower COVID-19 impact. Finally, the outcomes indicated that the male sex moderates the failure and imperfection schemas and the perceived impact on occupational and physical health, while the female sex moderates the attachment schemas and the global impact. These findings underscore the necessity of incorporating variables such as sex and GD when tailoring strategies for prevention, evaluation, and intervention for individuals. Additionally, the significance of adopting a gender-inclusive perspective was emphasized.
Access to senior secondary science and mathematics: examining the evidence for stratification in an Australian school system
Authors: Dean Jenny , Roberts Philip , Murphy Steve
Published: November 2023

This research investigates access to senior school science and mathematics subjects offered in the final year of secondary schooling. Using data from the most populous Australian state of New South Wales, we examine whether stratification occurs in access to science and mathematics curricula. We find that the opportunity to study these subjects differs by key school characteristics, including location, socioeconomic composition and school sector. We find that while some science subjects and entry level mathematics are offered in most schools, substantial inequalities exist in access to the most advanced level of mathematics and chemistry. School location, socioeconomic composition, enrolment size and the availability of teachers predict the probability of whether a school offers the least and most advanced science and mathematics subjects. The findings highlight that stratification in curricula offerings occurs systemically and may intensify educational inequalities.
Synthesis and characterization of nanocomposites containing Buchholzia coriacea pod decorated with multi-walled carbon nanotubes for remediation of rhodamine B dye from aqueous solution
Authors: Amaku James Friday , Taziwa Raymond
Published: November 2023

A novel nanocomposite (WKM) was synthesized by crosslinkingBuchholzia coriaceapod (WK) andf-MWCNTs for the efficient adsorption of rhodamine B (RhB) from wastewater. The uptake of RhB onto WK and WKM was influenced by initial pH, adsorbent dose, the temperature of the adsorptive system, contact time and initial RhB concentration. Optimum experimental conditions of 100 min agitation time, 0.05 g dosage, solution pH 3.0 and 100 mg dm−3initial concentration were obtained. The uptake of RhB onto WK and WKM was well expressed by Freundlich isotherm and a monolayer maximum uptake capacity of 67.82 mg g−1and 87.58 mg g−1was determined for WK and WKM, respectively. The adsorption of RhB onto WKM and WK followed the Elovich and pseudo-first-order kinetic models, respectively. Thermodynamic parameters such as ∆G°, ∆H° and ∆S° reveal that the uptake of RhB onto WK and WKM was spontaneous and endothermic. Meanwhile, WKM demonstrated excellent reusability. Hence, this study presents a nanocomposite (WKM) with robust potential for RhB removal.

Published: November 2023

A growing number of global ocean conflict studies over the last decade have set out to advance sustainability in the Anthropocene. Many of these research projects use multiple case studies to extract lessons for wider contexts. The methods used by these studies, and the extent to which their results have validity beyond the individual case study, often remain unclear. This paper explores the challenges in performing cross-case analysis within what we denote as case-based globally focussed sustainability projects (CB-GSPs) and indicates solutions by combining information from semi-structured interviews with leading scientists from eight CB-GSPs. We identify six distinct challenges that are common across these studies with regard to generating actionable knowledge through cross-case analysis. Based on these findings, we propose a set of best practice recommendations for scientists, project partners, and funders to co-produce actionable knowledge for global projects on ocean conflict.
A continuous toolpath strategy from offset contours for robotic additive manufacturing
Authors: Nguyen Xuan Anh , King Peter , Vargas-Uscategui Alejandro , Lohr Hans , Chu Clement
Published: November 2023

Toolpath planning is an essential component of robotic additive manufacturing. An efficient toolpath strategy allows parts to be made that are geometrically accurate, free of defects, have good mechanical properties and have low residual stress. Toolpaths for cold spray additive manufacturing have some technical constraints that need to be considered compared to their counterpart designed for conventional 3D printing machines. This study presents an automated toolpath planning method based on offset contours. The generated toolpath is globally continuous, layer-wise setting, making it suitable for robotic cold spray additive manufacturing. The toolpath algorithm was tested on a variety of geometries to demonstrate its robustness. One model was selected for printing using a commercial high-pressure cold spray system. The experimental results show that our method is applicable to cold spray robotic additive manufacturing for near-net shape construction. The method is particularly good for web-rib structures.

La sindrome dell’ovaio policistico (PCOS) è il più frequente disordine endocrino nelle donne in età riproduttiva, con una prevalenza stimata tra il 5 e il 24% in base alla popolazione di riferimento. Le sue caratteristiche cliniche possono influenzare la salute sessuale e riproduttiva della donna, sebbene la letteratura inerente questo argomento non esprima al momento attuale dati definitivi, ma anzi spesso contrastanti. L’obiettivo di questa rassegna è analizzare l’impatto della PCOS sulla sfera della sessualità, prendendo in considerazione le sue manifestazioni cliniche e le eventuali comorbidità associate.
Semisupervised regression in latent structure networks on unknown manifolds
Authors: Acharyya Aranyak , Agterberg Joshua , Trosset Michael W. , Park Youngser , Priebe Carey E.
Published: November 2023

Random graphs are increasingly becoming objects of interest for modeling networks in a wide range of applications. Latent position random graph models posit that each node is associated with a latent position vector, and that these vectors follow some geometric structure in the latent space. In this paper, we consider random dot product graphs, in which an edge is formed between two nodes with probability given by the inner product of their respective latent positions. We assume that the latent position vectors lie on an unknown one-dimensional curve and are coupled with a response covariate via a regression model. Using the geometry of the underlying latent position vectors, we propose a manifold learning and graph embedding technique to predict the response variable on out-of-sample nodes, and we establish convergence guarantees for these responses. Our theoretical results are supported by simulations and an application to Drosophila brain data.

Quantification of overnight urinary gonadotropin excretion predicts imminent puberty in girls: a semi-longitudinal study
Authors: Demir And , Büyükgebiz Atilla , Aydin Adem , Hero Matti
Published: November 2023

Purpose

We explored the alternative of using overnight fold change in gonadotropin levels by comparing the last-night-voided (LNV) and first-morning-voided (FMV) urine concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) as a conceptual analogy to the invasive gonadotropin-releasing hormone (GnRH) stimulation test setting.

Methods

We investigated the nocturnal changes in the immunoreactivity levels of urinary gonadotropins between early and late prepubertal stages as well as between early and late pubertal stages in FMV and LNV urine samples from 30 girls, of whom those who were prepubertal were further investigated through follow-up visits within the 1-year period from the start of the study.

Results

ROC analysis revealed that the FMV total U-LH and FMV U-FSH concentrations at or above 0.3 IU/L and 2.5 IU/L, respectively, were excellent predictors of forthcoming onset of puberty within 1 year (100% sensitivity, 100% specificity, AUC: 1.00, and n = 10, for both). FMV total U-LH concentration at or above 0.8 IU/L represented the cut-off for clinical signs of puberty. FMV/LNV total U-LH and FMV/LNV U-FSH ratios at or below 4.11 and 1.38, respectively, were also good predictors of the onset of clinical puberty within 1 year. An overnight increase (FMV/LNV ratio) in total U-LH concentrations and in the U-LH/U-FSH ratio at or below 1.2-fold in pubertal girls was associated with the postmenarcheal pubertal stage.

Conclusion

FMV total U-LH and U-FSH above 0.3 IU/L and 2.5 IU/L, respectively, can be used as cut-off values to predict the manifestation of the clinical signs of puberty within 1 year. FMV total U-LH concentrations 0.3–0.8 IU/L and 0.6 IU/L may represent the range and the threshold, respectively, that reflect the loosening of the central brake on the GnRH pulse generator. An overnight increase of 20% or less in total U-LH concentrations and in the U-LH/U-FSH ratio in an early pubertal girl may serve as an indicator of imminent menarche, a presumed timing of which can be unraveled by future longitudinal studies.

Authors: Mattlet Agnès , Sicot Olivier , Van Schoors Laetitia , Aivazzadeh Shahram
Published: November 2023

The manufacturing by thermocompression of flax fiber composites requires a good understanding of process parameters. This work focuses on the influence of key parameters in the manufacture of quality unidirectional flax/polypropylene composites by thermocompression. To this effect, a number of matrix and process parameters have been studied and ranked according to their influence on composite morphology and tensile properties. Among tested parameters, process time and temperature tend to decrease tensile strength as they increased from 3 to 11 min and from 180 to 200 °C. As a result, decrease of cooling speed from 15 to 5 °C min−1 also decreased tensile strength. Temperature of 180 °C also led to composites with no dispersion of fibers. Using a compatibilized agent, maleic anhydride grafted polypropylene (PP), also increased tensile strength of composites. Increasing its percentage from 3 to 5% increased tensile properties in the 90° direction. Pressure had no significant effect on mechanical properties, though lower pressures increase fiber dispersion.
Effect of physical and chemical activation methods on the structure, optical absorbance, band gap and urbach energy of porous activated carbon
Authors: Shahcheragh S. K. , Bagheri Mohagheghi M. M. , Shirpay A.
Published: November 2023

In this study, activated carbon was synthesized using the almond shell and palm kernel by physical activation with water vapor and chemical activation with phosphoric acid (H3PO4) methods. Then, the structural and optical properties of the activated carbons were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV–Vis spectroscopy. The SEM images showed that in the raw sample of hard almond shell and palm kernel, there is no porosity and pores, but in the activated carbon samples, porosity and structural defects were clearly observed. The XRD patterns showed that porous and amorphous structure was formed in all samples synthesized with physical and chemical activation. The results of FTIR spectra of activated carbons showed that there are carbon functional groups in all samples. The optical absorption coefficient (α) of the activated carbon with physical and chemical activation methods was obtained in order of 105–106. The band gap measurement of porous nanostructures showed that the activated carbon synthesized with chemical and physical activation methods have energy gap (Eg) in region = 2.80 to 3.15 eV and urbach energy (EU) in region = 120 to 210 meV.

Published: November 2023

Community-based and culturally grounded research, led by Indigenous scholars, is critical for the prevention and intervention of health risks such as substance use and misuse in Indigenous communities. However, Indigenous scholars encounter numerous adversities to success in academia. This manuscript describes an Indigenous Writing Retreat (IWR) guided by Native Hawaiian worldview and ontology held in Hawaiʻi in Spring 2022 to empower eleven Indigenous scholars and four mentors through cultivating their Form (intellectual knowledge) and Essence (expression of true intention and authentic feeling). Intentions of this gathering were as follows: (1) Hoʻoulu a Hoʻomōhalahala ʻIke: inspire growth/develop knowledge and insight; (2) Hōʻola i ka Nohona Kanaka: give life to cultural identity and native intelligence; (3) Hoʻopono: cleanse and let go; and (4) Hoʻohana Pilina: relationship building with each other, land, and spirit. Intentions were achieved through six methods: (1) academic writing; (2) Indigenous Cultural Orientation and Protocol; (3) honor and pay respect for people and land; (4) cultural tools and ceremony; (5) create a “Safe Space”; and (6) community building. This story conveys the IWR impact on scholars, mentors, and community hosts, including kūpuna (Elders)/leaders/cultural practitioners via a survey, email exchanges, and “talk story” sessions with them. Four relational actions (recommendations) for future IWRs are presented using the acronym PONO: Preparation, Observation, Navigation, and Oneness. This IWR is offered as a gift to all Indigenous nations to inspire and guide relational exchanges and cultivate Indigenous leadership in substance use research, collective well-being, and resilience by centering Indigenous worldviews and methodologies.

Trends in Brain Research: A Bibliometric Analysis
Authors: Simard Marc-André , Kozlowski Diego , Segal Julia , Messer Mia , Ocay Don Daniel , Saari Toni , Ferland Catherine E. , Larivière Vincent
Published: November 2023

Background:

Bibliometrics methods have allowed researchers to assess the popularity of brain research through the ever-growing number of brain-related research papers. While many topics of brain research have been covered by previous studies, there is no comprehensive overview of the evolution of brain research and its various specialties and funding practices over a long period of time.

Objective:

This paper aims to (1) determine how brain research has evolved over time in terms of number of papers, (2) countries' relative and absolute positioning in terms of papers and impact, and (3) how those various trends vary by area.

Methods:

Using a list of validated keywords, we extracted brain-related articles and journals indexed in the Web of Science over the 1991–2020 period, for a total of 2,467,708 papers. We used three indicators to perform: number of papers, specialization, and research impact.

Results:

Our results show that over the past 30 years, the number of brain-related papers has grown at a faster pace than science in general, with China being at the forefront of this growth. Different patterns of specialization among countries and funders were also underlined. Finally, the NIH, the European Commission, the National Natural Science Foundation of China, the UK Medical Research Council, and the German Research Foundation were found to be among the top funders.

Conclusion:

Despite data-related limitations, our findings provide a large-scope snapshot of the evolution of brain research and its funding, which may be used as a baseline for future studies on these topics.
Interaction and breakdown induced by multiple optimal disturbances in hypersonic boundary layer
Authors: Guo Peixu , Hao Jiaao , Wen Chih-Yung
Published: November 2023

The present paper finds that the coexistence of multiple primary instability waves may cause a non-trivial nonlinear interaction and breakdown process, which has not been reported before. In the considered Mach 6 flat-plate boundary layer, a global resolvent analysis reports three optimal disturbances (local maxima): a high-frequency planar wave, a low-frequency oblique wave and a stationary streak. For the dominant planar and oblique waves, a parabolised stability equation analysis identifies the initial non-modal transient growth and downstream modal growth. Initiated by these two optimal disturbances jointly, the complete linear and nonlinear instability processes until breakdown to turbulence are shown with direct numerical simulation. Owing to the transient growth, the oblique wave may be more significant than the planar wave in the breakdown. The oblique wave and scales of nonlinear interactions are pronounced in the outer layer, whose significance may not be comprehensively characterised by the wall pressure measurement. Fourier modes characterising the oblique-wave oblique breakdown, the planar-wave fundamental resonance, the planar-wave subharmonic resonance and the combination resonance related to a detuned mode are observed successively. The detuned mode seems to dominate the near-wall dynamics in the late nonlinear stage, characterised by

$\varLambda$

-like structures. Meanwhile, the existence of this detuned mode is independent of the initial amplitude ratio and the absolute amplitude of the oblique and planar waves. Weakly nonlinear stability analyses demonstrate that the detuned mode is mainly a consequence of the secondary instability under the combination of planar and oblique primary waves. Wave vector plots reveal the resonant state of multiple triads. Energy budget and amplitude-correction analyses provide a clear physical image of energy transfer.
Vorticity forces of coherent structures on the NACA0012 aerofoil
Authors: Chiu Te-Yao , Tseng Chien-Chou , Chang Chien-Cheng , Chou Yi-Ju
Published: November 2023

This study examined the impact of coherent structures on the aerodynamic forces exerted on a NACA0012 aerofoil with angles of attack

$7.5^{\circ }$

and

$10^{\circ }$

, and a chord-based Reynolds number

$50\,000$

. The study utilized the spectral proper orthogonal decomposition (SPOD) algorithm to identify the coherent structures, and vorticity force analysis to quantify their impact on lift and drag forces. Results showed that at

$10^{\circ }$

, the zeroth frequency of the first SPOD mode had a significant impact on drag and lift forces due to a large vortex structure that caused a strong flow along the suction side of the aerofoil. The first and second frequencies of the first SPOD mode represented asymmetric vortex pairs and a series of vortex pairs that determined the leading-edge separation, respectively. At

$7.5^{\circ }$

, the zeroth frequency of the first mode corresponded to an oscillating near-wall stream that followed the reattachment flow pattern, while the first frequency corresponded to a counter-rotating vortex pair that originated where the flow reattaches. Finally, the second frequency of the first mode corresponded to smaller counter-rotating vortex pairs at the shear layer originated near the reattachment point. These findings suggest that coherent structures have a significant impact on aerodynamic forces exerted on aerofoils, and can be identified and quantified using the SPOD algorithm and vorticity force analysis.
Discovering optimal flapping wing kinematics using active deep learning
Authors: Corban Baptiste , Bauerheim Michael , Jardin Thierry
Published: November 2023

This paper focuses on the discovery of optimal flapping wing kinematics using a deep learning surrogate model for unsteady aerodynamics and multi-objective optimisation. First, a surrogate model of the unsteady forces experienced by a 3-D flapping wing is built, based on deep neural networks. The model is trained on a dataset of randomly generated kinematics simulated using direct numerical simulation (DNS). Once trained, the neural networks can quickly predict the unsteady lift and torques experienced by the wing, using sparse information on the kinematics. This fast surrogate model allows multi-objective optimisation to be performed. The resulting Pareto front consists of new kinematics that may be very different from the kinematics of the initial dataset. A few arbitrarily chosen kinematics on the Pareto front are thus simulated using DNS and used to enhance the database. The new dataset is used to train again the networks, and this active deep learning/optimisation framework is performed until convergence, obtained after only two iterations. Overall, this method reduced the cost of optimisation by 83 %. Results reveal two distinct families of motions. Kinematics promoting high efficiency are characterised by large stroke amplitudes and relatively low angles of attack, as observed for fruit flies, honeybees or hawkmoths. For those, lift production is driven by quasi-steady effects and the formation of a stable leading edge vortex. Kinematics promoting high lift are characterised by small stroke amplitudes and high angles of attack, reminiscent of mosquitoes. Lift production is driven by the rapid generation of vorticity at the trailing edge.

‘PLUNDERING THE LIBERAL PHILOSOPHICAL TRADITION’? THE USE OR ABUSE OF ADAM SMITH IN PARLIAMENT, 1919–2023
Authors: Greene Zachary , Jasinski Jan M. , Roy Graeme , Schober Thomas , Scotto Thomas J.
Published: November 2023

The contemporary relevance of Adam Smith is evidenced by continued reference to his name. Computational analysis identifies over 700 mentions of Smith and his two famous works—The Theory of Moral Sentiments and The Wealth of Nations—in post-World War 1 House of Commons debates. We find some parliamentarians appreciate Smith’s complex ideas, but most references are ‘ornamental’. Charting Smith’s use over the decades, this paper builds on Kirk Willis’ idea that studying parliamentary debates are an ideal way to understand how, at best, policy ideas, germinate and disseminate over time, or, at worst, how ‘complex ideas became slogans’.
THE POTENTIAL OF BIOGENIC FRACTION ANALYSIS BY RADIOCARBON IN FOOD, DRUG, AND COSMETIC PRODUCTS
Authors: Varga Tamás , Szejke Dóra , Nemes Zoltán , Jull A J Timothy , Molnár Mihály
Published: November 2023

Biobased content analysis is a well-established, analytically independent, standardized method to determine the biobased content of fuels and plastics, based on differences of the specific radiocarbon (14C) activity of fossil and recent biogenic compounds. This biogenic content analysis can be useful for the producers as a quality assurance tool, for the customers as feedback about the truly biobased products and for the control organizations as an independent analytical tool to prove the biological origin. More than 100 commercially available foods, cosmetics, and drug samples have been used for biobased carbon content analysis by accelerator mass spectrometry (AMS) 14C measurement to demonstrate the potential of this technique. Our results show that this measurement technique is a unique tool for the determination of biocontent in foodstuff and medical products. Most of the tested materials were nearly or completely biobased (≥ 98 pMC), and no completely fossil-based final product was detected. The lowest biogenic compound was measured in a vanilla aroma flavor. In 45 of the 102 samples selected a wide range (2–98%) presented fossil-based carbon content. The method can be applied for monitoring raw materials and final products for biobased content in the industry and consumer protection as well.

This paper investigates the production of dental and retroflex stops, fricatives, nasals, and laterals in the Dravidian language Kannada. This is done using articulatory contours extracted from an extensive midsagittal MRI corpus of two female Kannada speakers’ static vocal tract postures intended to capture key aspects of phonemic articulations. Articulatory modelling was used to determine a set of components responsible for the implementation of place and manner contrasts (/t̪ s̪ n̪ l̪/ vs. /ʈ ʂ ɳ ɭ/). These components included both lingual and non-lingual articulatory parameters. Constriction location and length were also determined based on articulatory contours. The results showed that the two speakers produced non-fricative retroflexes with a retracted tongue tip making a constriction behind the alveolar ridge and a characteristic convex tongue shape, yet without a retraction of the posterior portion of the tongue. Apart from the lingual parameters, place differences were also manifested by the vertical position of the larynx (lower for retroflexes). The realisation of the place contrast in sibilant fricatives was different, as /ʂ/ appeared to be produced by both speakers with a laminal alveolopalatal constriction. Manner differences were captured by various non-lingual parameters, yet being also manifested in constriction locations (more anterior for stops). These findings are discussed in the context of previous descriptive and articulatory accounts of dental-retroflex contrasts.

Area-based conservation is a widely used approach for maintaining biodiversity, and there are ongoing discussions over what is an appropriate global conservation area coverage target. To inform such debates, it is necessary to know the extent and ecological representativeness of the current conservation area network, but this is hampered by gaps in existing global datasets. In particular, although data on privately and community-governed protected areas and other effective area-based conservation measures are often available at the national level, it can take many years to incorporate these into official datasets. This suggests a complementary approach is needed based on selecting a sample of countries and using their national-scale datasets to produce more accurate metrics. However, every country added to the sample increases the costs of data collection, collation and analysis. To address this, here we present a data collection framework underpinned by a spatial prioritization algorithm, which identifies a minimum set of countries that are also representative of 10 factors that influence conservation area establishment and biodiversity patterns. We then illustrate this approach by identifying a representative set of sampling units that cover 10% of the terrestrial realm, which included areas in only 25 countries. In contrast, selecting 10% of the terrestrial realm at random included areas across a mean of 162 countries. These sampling units could be the focus of future data collation on different types of conservation area. Analysing these data could produce more rapid and accurate estimates of global conservation area coverage and ecological representativeness, complementing existing international reporting systems.
Evil and evidence: a reply to Bass
Authors: Almeida Mike
Published: November 2023

In ‘Evil is Still Evidence: Comments on Almeida’ Robert Bass presents three objections to the central argument (ENE) in my ‘Evil is Not Evidence’. The first objection is that ENE is invalid. According to the second objection, it is a consequence of ENE that there can be no evidence for or against a posteriori necessities. The third objection is that, contrary to ENE, the likelihood of certain necessary identities varies with the evidence we have for them. In this reply I explain why ENE has exactly none of the implications described by Bass. I argue in the concluding section that there is a modal solution to the epistemological problems presented by ENE.
Envisaging the other Korea in English textbooks
Authors: Kim Sun–Hee , Lee Hikyoung
Published: November 2023

Textbooks have long been considered resources for empowering nationalism within historical, social and political contexts. In particular, nations which have experienced socio-political turmoil place emphasis on promoting learners’ national identity through a national curriculum and designated textbooks (So, Kim & Lee, 2012). These textbooks serve as a pedagogical tool that plays a pivotal role in how learners should position themselves in the face of globalization (Matsuda, 2012; Matsuda & Friedrich, 2011). By the same token, they are artifacts that reflect realities alongside certain ideologies and values that society expects its citizens to learn while consolidating national identity through formal language education (Norton, 2013; Pavlenko, 2003; Pavlenko & Norton, 2007). Recent studies have also revealed that government-authorized English textbooks tend to be less hesitant about dealing with historical disputes regarded as contentious in nature (see Kim & Lee, 2023).

Itaipu Hydroelectric Power Plant initiated a large reforestation programme after the expropriation of the areas destined for the formation of the reservoir. This study aimed to evaluate the effectiveness of forest restoration of the Seasonal Semideciduous Forest in the Upper Paraná Atlantic Forest ecoregion, Brazil, using epigaeic ant assemblages as bioindicators, by comparing ant species richness and composition in the Reservoir Protection Strip with adjacent areas, such as the primary forest of the Iguaçu National Park and the Permanent Preservation Area located on a rural property and agricultural areas. In total, 171 ant species were identified. Ant species richness was higher in forest than in agricultural areas and did not differ among forest areas. However, ant species composition in forest areas, regardless of the restoration technique used, was not similar to the primary forest, possibly due to variation in forest recovery time. This study highlights the great value of the Iguaçu National Park as a conservation unit. Also, it reveals that the efforts for the creation and maintenance of the Reservoir Protection Strip, which remains without anthropic interventions for years, might indeed lead to a complete recovery of the ant species composition over time, reinforcing their great importance for biodiversity conservation.
The Gold Standard and the international dimension of the Great Depression
Authors: Pensieroso Luca , Restout Romain
Published: November 2023

Was the Gold Standard a major determinant of the onset and protracted character of the Great Depression of the 1930s in the USA and worldwide? In this paper, we model the “Gold Standard hypothesis” in an open-economy, dynamic general equilibrium framework. We show that encompassing the international and monetary dimensions of the Great Depression is important to understand the turmoil of the 1930s. In particular, the Gold Standard turns out to be a strong transmission mechanism of monetary shocks from the USA to the rest of the world. Our results also suggest that the waves of successive nominal exchange rate devaluations coupled with the monetary policy implemented in the USA might not have enhanced the recovery.
Accounts of vulnerability within positive human rights obligations
Authors: Godden-Rasul Nikki , Murray C.R.G.
Published: November 2023

Accounts of human beings as vulnerable have provided powerful reposts to liberal individualism in recent decades. Concurrently, the European Court of Human Rights’ jurisprudence on Convention states’ positive obligations often obliges public authorities to address particular vulnerabilities. These developments reflect elements of different theoretical accounts of vulnerability but lack a coherent approach to the human subject. Exploring the impact of this in the UK Supreme Court’s jurisprudence, we evaluate two case studies in which positive obligations have been imposed on the police; (1) public order in the context of inter-community tensions in Northern Ireland (DB v. Chief Constable of Police Service of Northern Ireland) and (2) police investigations in regard to serial sexual offending (Commissioner of Police of the Metropolis v. DSD). This jurisprudence illustrates how some domestic judges are supplying their decisions with rationalisations which are lacking in the European Court’s case law.
What factors influence individual differences in vulnerability/resilience to sleep loss and/or circadian misalignment?
Authors: Cash Elizabeth , Beck Isak , Davis Christopher J.
Published: November 2023

Daily rhythms are primarily synchronized by the suprachiasmatic nucleus (SCN) in the hypothalamus, the body’s central circadian clock. The SCN aligns whole-body cellular, behavioral and phenomenological processes with the Earth’s 24-hour day/night rhythm. When disruptions to the SCN’s perceptual system occur (e.g., “jet-lag,” prolonged waking, chronic exposure to light at night or habit change as the result of becoming a parent), disrupted melatonin and glucocorticoid secretion can lead to widespread dysregulation of sleep and circadian cycling. The effects of circadian disruptions are often compounded by the homeostatic sleep drive, wherein sleep pressure accumulates with protracted wakefulness to affect mood, cognition, health and well-being.
Psychometric Evaluation of the Italian Version of the COVID-19 Vaccine Conspiracy Beliefs Scale
Authors: Pisanti Renato , Soraci Paolo
Published: November 2023

Abstract: Introduction: The present study adapted the Vaccine Conspiracy Beliefs Scale (VCBS ) developed by Shapiro and colleagues (2016) in the specific context of COVID-19 and examined the psychometric properties of an Italian version of the scale (VCBS-COVID19/Ita). Methods: We modified the 7 items of the VCBS to address conspiracy beliefs specifically regarding COVID-19 vaccines and translated them into Italian. We collected the data from a group of 1,179 subjects (73% female). We used confirmatory factor analysis (CFA) to examine the dimensional structure of the VCBS-COVID19/Ita and multigroup CFA (MG CFA) to evaluate the measurement invariance across gender. Results: We found support for a one-factor solution for the VCBS-COVID19/Ita. The one-factor model was factorially invariant across gender. Additionally, we determined the VCBS-COVID19/Ita scores to be associated with COVID-VAX dimensions, providing support for the convergent and divergent validity of the Italian version of the VCBS-COVID19. Discussion: Our results provide evidence that the Italian version of the VCBS-COVID19 is reliable, valid, and, thus, potentially useful for research on COVID-19. Study limitations and future research directions are discussed.
