Published: March 2023

Abstract
Objective
Maps of B0 field inhomogeneities are often used to improve MRI image quality, even in a retrospective fashion. These field inhomogeneities depend on the exact head position within the static field but acquiring field maps (FM) at every position is time consuming. Here we propose a forward simulation strategy to obtain B0 predictions at different head-positions.

Methods
FM were predicted by combining (1) a multi-class tissue model for estimation of tissue-induced fields, (2) a linear k-space model for capturing gradient imperfections, (3) a dipole estimation for quantifying lower-body perturbing fields (4) and a position-dependent tissue mask to model FM alterations caused by large motion effects. The performance of the combined simulation strategy was compared with an approach based on a rigid body transformation of the FM measured in the reference position to the new position.

Results
The transformed FM provided inconsistent results for large head movements (> 5° rotation, approximately), while the simulation strategy had a superior prediction accuracy for all positions. The simulated FM was used to optimize B0 shims with up to 22.2% improvement with respect to the transformed FM approach.

Conclusion
The proposed simulation strategy is able to predict movement-induced B0 field inhomogeneities yielding more precise estimates of the ground truth field homogeneity than the transformed FM.

AbstractVigilance, a crucial factor affecting the behaviour of birds, is key to the safety of migratory animal flocks against predators and other threats. We examined the vigilance of White-fronted Geese in the Biebrza Basin (NE Poland), one of their major stopover sites in Europe. The study took place during their spring staging, from the end of February until the beginning of April. We found that the vigilance of White-fronted Geese decreased in the centre of mixed flocks with Greylag Geese. This may be associated with the larger size and wider field of view of Greylag Geese, as well as their territorial behaviour, as some of them belong to the local breeding population. White-fronted Geese can benefit from the group-size effect when they form larger flocks. In the presence of a vigilance stimulus, the individuals in the centre of a flock raised their alertness levels. As the probability of detecting danger is higher in large groups, flock size negatively affected the birds’ vigilance. Owing to their different experience and roles (adults care for their broods by being vigilant), adult birds appeared to be vigilant on both grassland and arable land, whereas immatures were vigilant only on arable land, where exposure to predatory pressure was greater. We believe that the lower level of vigilance of White-fronted Geese in large and mixed flocks may give them more time for foraging and, therefore, improve their chances of survival and breeding success during the oncoming spring.

Abstract
Aim
Research on the health checkup status of urban residents in Southwest China is limited. In this study, we aimed to investigate the current status of health checkups and explore their influencing factors by analyzing the cognition, attitudes, and practices of urban residents in Southwest China.

Methods
We sampled 1200 urban residents for a questionnaire survey. Statistical analysis was performed using SPSS 23, and logistic regression analysis was used to analyze the factors affecting cognition, attitudes, and practices regarding health checkups. A P value < 0.05 was used to identify variables significantly associated with the outcome variable.

Results
Overall, 29% of the residents understood the importance of health checkups. The main ways urban residents acquire health-related knowledge are through the use of mobile media and medical staff health education. Only 40% of residents had undergone a regular checkup. Health self-assessment, economic reasons, and time are the factors that interfere with urban residents’ health checkups. Logistic regression analysis showed that occupation status, educational background, self-assessed health status, exercise status, and monthly income level were the common influencing factors of health checkup cognition and planning. Whether residents had participated in a medical checkup program was also related to sex and age.

Conclusions
Urban residents in Southwest China generally had a high willingness to undergo physical examinations, but there were differences in knowledge and practice; at the same time, residents lacked understanding of respiratory assessments. Improving the health literacy of medical staff, strengthening urban residents’ health education, and enhancing the utilization rate of health checkups in urban residents are necessary and urgent.

Published: March 2023

AbstractEliminating adolescent HIV in high-burden African countries depends on the success of implementing evidence-based interventions to reduce transmission and improve treatment outcomes. The Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) takes a collaborative approach to addressing key challenges and identifying and developing new areas of investigation to advance the adolescent HIV agenda. This special supplement represents the collective learning of the Alliance related to implementation science in the context of the adolescent HIV continuum of care from multiple African countries. Specifically, this series describes the current academic landscape of adolescent HIV and implementation science, such as the methodological use and utility of implementation measures and frameworks; addresses timely topics such as the use of innovative technologies for study adaptations in the context of the global COVID-19 pandemic; and explores opportunities to enhance adolescent-responsive approaches to HIV prevention and treatment using implementation science.

Published: March 2023

AbstractChemsex is common among gay, bisexual and other men who have sex with men (gbMSM). Although not always categorised as problematic, a link with psychological distress has been reported and might be exacerbated amongst gbMSM living with HIV, as HIV has been associated with anxiety and depression. A cross-sectional online survey of gbMSM living with HIV (n = 359) was performed incorporating the Hospital Anxiety and Depression Scale and sociodemographic variables including, HIV characteristics, chemsex and sexual behaviours. Logistic regression analysis was used to find associations with anxiety or depression. Many participants engaged in chemsex (48.5%, n = 174). Chemsex was associated with lower odds of depression (aOR 0.45, 95% CI 0.23–0.85) and not associated with anxiety (aOR 0.66, CI 0.40–1.09). Although chemsex is a public health concern; we found it was associated with lower levels of depression in gbMSM living with HIV. However, causal inference is not possible, as gbMSM with higher levels of depression might engage in chemsex less.

Published: March 2023

AbstractThe release of Tamarixia triozae (Burks) (Hymenoptera: Eulophidae), a parasitoid of the potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), resulted in the successful establishment of the parasitoid in New Zealand. The parasitoid was released at more than 30 sites by the final year of the three-year study throughout New Zealand. Its continued presence over the three-year study was confirmed in two regions (Hawke’s Bay and Canterbury). At one site in Canterbury, the parasitoid was released only in the first summer of this study (Nov. 2017–Feb. 2018). It was recovered from potato psyllid infested African boxthorn (Lycium ferocissimum Miers) foliage in the second and third summers at this site, demonstrating the parasitoid’s ability to survive over successive winters. We found T. triozae parasitized nymphs at 24 sites of the 86 potato psyllid host plant sites surveyed within a 25 km radius of known release sites in Hawke’s Bay. The parasitoid was found up to 24 km from the nearest known release site in Hawke’s Bay. In Canterbury, the parasitoid was found up to 0.6 km from a known release site. Parasitism rates of 13.7–15.6% were estimated based on two post-release survey methods employed in this study. The parasitoid also feeds on psyllid nymphs so its establishment may lead to helping to reduce or delay potato psyllid populations from reaching damaging levels. Long-term monitoring is needed to determine the consequences of importing T. triozae on populations of potato psyllid.
Design and construction of Guayaquil radio speech corpus (CHARG)
Authors: Sawicka-Stępińska Brygida 
Published: March 2023

AbstractThe present paper aims to describe the process of creating CHARG—Corpus de Habla Radiofónica de Guayaquil (the Guayaquil Radiophonic Speech Corpus). It is the first systematized spoken corpus for this rather under-researched variety of Spanish. Guayaquil is the most populated city of Ecuador, while its capital city is Quito. Therefore, Ecuador is a rare case of a Spanish-speaking country with two major urban centers that belong to two separate dialectal zones, offering a very peculiar sociolinguistic context. CHARG is a corpus composed of Guayaquil radio programs. Its structure is organized by non-linguistic criteria (program type) in order to ensure a representative and balanced sample. The paper describes the design of the corpus (defining the study population, sample and stratification) and its construction (recording procedure, speakers and speech style coding, transcription and annotation). As a result, CHARG consists of 24 h of transcriptions and annotations of recordings from 142 speakers. The paper’s potential use is twofold: since it presents a step-by-step procedure of corpus construction that can be replicated, the readers might be interested in both the procedure and the corpus itself as a research material.

AbstractBackgroundNeuronal ceroid lipofuscinosis is a group of neurodegenerative disorders with varying visual dysfunction.CLN3is a subtype which commonly presents with visual decline. Visual symptomatology can be indistinct making early diagnosis difficult. This study reports ocular biomarkers ofCLN3patients to assist clinicians in early diagnosis, disease monitoring, and future therapy.MethodsRetrospective review of 5 confirmedCLN3patients in our eye clinic. Best corrected visual acuity (BCVA), electroretinogram (ERG), ultra-widefield (UWF) fundus photography and fundus autofluorescence (FAF), and optical coherence tomography (OCT) studies were undertaken.ResultsFive unrelated children, 4 females and 1 male, with median age of 6.2 years (4.6–11.7) at first assessment were investigated at the clinic from 2016 to 2021. Four homozygous and one heterozygous pathogenicCLN3variants were found. Best corrected visual acuities (BCVAs) ranged from 0.18 to 0.88 logMAR at first presentation. Electronegative ERGs were identified in all patients. Bull’s eye maculopathies found in all patients. Hyper-autofluorescence ring surrounding hypo-autofluorescence fovea on FAF was found. Foveal ellipsoid zone (EZ) disruptions were found in all patients with additional inner and outer retinal microcystic changes in one patient. Neurological problems noted included autism, anxiety, motor dyspraxia, behavioural issue, and psychomotor regression.ConclusionsCLN3patients presented at median age 6.2 years with visual decline. Early onset maculopathy with an electronegative ERG and variable cognitive and motor decline should prompt further investigations including neuropaediatric evaluation and genetic assessment forCLN3disease. The structural parameters such as EZ and FAF will facilitate ocular monitoring.

Abstract
Managing agricultural watersheds in an environmentally friendly manner necessitate the strategic implementation of well-targeted sustainable land management (SLM) practices that limit soil and nonpoint source pollution losses and translocation. Watershed-scale SLM-scenario modeling has the potential to identify efficient and effective management strategies from the field to the integrated landscape level. In a case study targeting a 66-hectare watershed in Petzenkirchen, Lower Austria, the Soil and Water Assessment Tool (SWAT) was utilized to evaluate a variety of locally adoptable SLM practices. SWAT was calibrated and validated (monthly) at the catchment outlet for flow, sediment, nitrate-nitrogen (NO3–N), ammonium nitrogen (NH4–N), and mineralized phosphorus (PO4–P) using SWATplusR. Considering the locally existing agricultural practices and socioeconomic and environmental factors of the research area, four conservation practices were evaluated: baseline scenario, contour farming (CF), winter cover crops (CC), and a combination of no-till and cover crops (NT + CC). The NT + CC SLM practice was found to be the most effective soil conservation practice in reducing soil loss by around 80%, whereas CF obtained the best results for decreasing the nutrient loads of NO3–N and PO4–P by 11% and 35%, respectively. The findings of this study imply that the setup SWAT model can serve the context-specific performance assessment and eventual promotion of SLM interventions that mitigate on-site land degradation and the consequential off-site environmental pollution resulting from agricultural nonpoint sources.

Published: March 2023

AbstractThe manufacturing domain is regarded as one of the most important engineering areas. Recently, smart manufacturing merges the use of sensors, intelligent controls, and software to manage each stage in the manufacturing lifecycle. Additionally, the increasing use of point clouds to model real products and machining tools in a virtual space facilitates the more accurate monitoring of the end-to-end production lifecycle. Thus, the conjunction of both, intelligent methods and more accurate 3D models allows the prediction of uncertainties and anomalies in the manufacturing process as well as reduces the final production costs. However, the high complexity of the geometrical structures defined by point clouds and the high accuracy required by the Quality Assurance/Quality control parameters during the process, pave the way for continuous improvements in smart manufacturing methods. This paper addresses a comprehensive analysis of machining tool identification utilizing temporal point cloud data. Specifically, we deal with the identification of machining tools from temporal 3D point clouds. To do that, we propose a process to construct and train intelligent models utilizing such data. Moreover, in our case study, we provide the research community with two labeled temporal 3D point cloud datasets, and we experiment with the pioneering PointNet neural network and three of its variants demonstrating an accuracy of 95% in the identification of the utilized machining tools in a machining process. Finally, we provide a prototype end-to-end intelligent system of machining tool identification.

AbstractNanostructured 0.52 Bi2O3–0.18 Fe2O3–0.30 PbTiO3 (BFPT) mol% sample was prepared via a high-energy planetary ball mill. To obtain nanostructured materials, the mixture was mechanically milled for 1, 2, 5, and 25 h. The heat treating process was applied to the milled BFPT sample at 673, 873, and 1073 K for 5 h. The amorphous natures of the as-milled and crystallized formed phases of the heat treated samples are examined using the X-ray diffraction (XRD) technique. HRTEM and XRD were used to confirm the amorphous nature and nanocrystallization of the milled and the heat treated BFPT samples, respectively. The effect of the heat-treatment temperature of BFPT samples on their dc electrical conductivity (σ), density (ρ), and oxygen molar volume (Vm) was studied. The results of the thermoelectric power indicate a p-type semiconducting behavior of the BFPT samples. The high temperature (above θD/2) dependent on conductivity was explicated by the small polaron hopping (SPH) model. While Greaves’ variable range hopping (VRH) model was studied at intermediate temperatures. The physical parameters determined from the best fits of these models were thought to be reasonable and consistent with the BFPT samples. The hopping carrier mobility was found to be the dominant factor for determining the conductivity in the BFPT samples. The electronic transport between Fe ions was primarily responsible for the conduction, which was shown to obey the adiabatic SPH.
Collective negative shocks and preferences for redistribution: Evidence from the COVID-19 crisis in Germany
Authors: Luna Bellani , Andrea Fazio , Francesco Scervini 
Published: March 2023

AbstractUsing new data from a three-wave panel survey administered in Germany between May 2020 and May 2021, this paper studies the impact of a negative shock affecting all strata of the population, such as the development of COVID-19, on preferences for redistribution. Exploiting the plausibly exogenous change in the severity of the infection rate at the county level, we show that, contrary to some theoretical expectations, the worse the crisis, the less our respondents expressed support for redistribution. We provide further evidence that this is not driven by a decrease in inequality aversion but might be driven by the individuals’ level of trust.

Published: March 2023

Abstract
Purpose
Intimate Partner Violence and Abuse (IPVA) is as a major health concern globally. The prevalence of IPVA perpetration and victimisation has been found to be higher in military compared to civilian populations. Of concern, help-seeking for other psychosocial difficulties among military communities has been shown to be both limited and challenging, and military personnel could face additional or amplified barriers to help-seeking for IPVA than their civilian counterparts. This study aimed to use qualitative methods to explore the experiences of, and barriers to, help-seeking for IPVA victimisation and perpetration among UK military personnel.

Methods
Thematic analysis was conducted on 40 one-to-one semi-structured interviews with military personnel (29 male, 11 female).

Results
Four superordinate themes were derived, thematically organised according to different levels of the social ecological model: Military cultural factors; Support service factors; Interpersonal factors; and Individual factors. At a military cultural level, participants described difficulties in help-seeking for IPVA resulting from widespread stigma and hypermasculine attitudes in military communities, minimisation of violence, perceived pressure from chain of command, and fear of consequences of reporting. At a support-service level, participants’ negative views or experiences and lack of awareness of services were also significant in deterring help-seeking. At an interpersonal level, participants recounted how relationships with military colleagues, their partner and their family could be both instrumental or a hindrance to help-seeking for IPVA. At an individual level, lack of insight into IPVA and different forms of abuse were suggested through minimisation of violence and described to contribute to delay in help-seeking. Shame, compounded by multi-layered stigma present at each social ecological model level, was a key reason for delaying or avoiding help-seeking.

Conclusions
The findings indicate the added challenges in help-seeking for IPVA experienced by military personnel and highlight a need for a whole systems approach to improve the provision of support for IPVA in the military serving and ex-serving community to instil meaningful change.

Published: March 2023

AbstractBodily engagement with the material and sociocultural world is ubiquitous in doing and learning science. However, science education researchers have often tended to emphasize the disembodied and nonmaterial aspects of science learning, thereby overlooking the crucial role of the body in meaning-making processes. While in recent years we have seen a turn towards embracing embodied perspectives, there persist considerable theoretical and methodological differences within research on embodiment in science education that hamper productive discourse. What is needed is a careful examination of how different traditions and disciplines, among them philosophy, social semiotics, and cognitive science, bear on embodiment in science education research. This paper aims to explore and articulate the differences and convergences of embodied perspectives in science education research in the form of a dialogue between three fictitious personas that stand for the cognitive, social-interactionist, and phenomenological research traditions. By bringing these traditions into dialogue, we aim to better position the role of the body in the science education research landscape. In doing so, we take essential steps towards unifying terminology across different research traditions and further exploring the implications of embodiment for science education research.
