AbstractAstragalus (Fabaceae) is astoundingly diverse in temperate, cold arid regions of Earth, positioning this group as a model clade for investigating the distribution of plant diversity in the face of environmental challenges. Here, we identify the spatial distribution of diversity and endemism in Astragalus using species distribution models for 752 species and a phylogenetic tree comprising 847 species. We integrated these to map centers of species richness (SR) and relative phylogenetic diversity (RPD) and used randomization approaches to investigate centers of endemism. We also used clustering methods to identify phylogenetic regionalizations. We then assembled predictor variables of current climate conditions to test environmental factors predicting these phylogenetic diversity results, especially temperature and precipitation seasonality. We find that SR centers are distributed globally at temperate middle latitudes in arid regions, but the Mediterranean Basin is the most important center of RPD. Endemism centers also occur globally, but Iran represents a key endemic area with a concentration of both paleo‐ and neoendemism. Phylogenetic regionalization recovered an east‐west gradient in Eurasia and an amphitropical disjunction across North and South America; American phyloregions are overall most closely related to east and central Asia. SR, RPD, and lineage turnover are driven mostly by precipitation and seasonality, but endemism is driven primarily by diurnal temperature variation. Endemism and regionalization results point to western Asia and especially Iran as a biogeographic gateway between Europe and Asia. RPD and endemism highlight the importance of temperature and drought stress in determining plant diversity and endemism centers.

AbstractThe results of earthquake damage certification (EDC) surveys are the basis of support measures for improving the lives of disaster victims. To address issues such as a limited workforce to perform EDC surveys and difficulties in judging the level of damage, a damage detection and level classification method for wooden houses using multiple convolutional neural network models is proposed. The proposed method, including detection, filtering, and classification models, was trained and validated based on photographs collected from EDC surveys in Uki City, Kumamoto Prefecture. Then, a software system, which deployed these models, was developed for the onsite EDC surveyors to detect damages shown in the photographs of the surveyed house and classify damage levels. The test results based on 32 target buildings indicate that the detection model achieved high recall in detecting damage. Moreover, the redundant detected regions can be precisely filtered by the filtering model. Finally, the classification model achieved relatively high overall accuracy in classifying the damage level.

Summary

Diatoms are a diverse group of phytoplankton usually dominating areas characterized by rapidly shifting light conditions. Because of their high growth rates and interesting biochemical profile, their biomass is considered for various commercial applications. This study aimed at identifying strains with superior growth in a photobioreactor (PBR) by screening the natural intraspecific diversity of ecotypes isolated from different habitats. We investigated the effect of PBR light fluctuating on a millisecond scale (FL, simulating the light in a PBR) on 19 ecotypes of the diatom Skeletonema marinoi isolated from the North Sea–Baltic Sea area.

We compare growth, pigment ratios, phylogeny, photo‐physiological variables and photoacclimation strategies between all strains and perform qPCR and absorption spectra analysis on a subset of strains.

Our results show that the ecotypes responded differently to FL, and have contrasting photo‐physiological and photoprotective strategies. The strains from Kattegat performed better in FL, and shared common photoacclimation and photoprotection strategies that are the results of adaptation to the specific light climate of the Kattegat area.

The strains that performed better with FL conditions had a high light (HL)‐acclimated phenotype coupled with unique nonphotochemical quenching features. Based on their characteristics, three strains were identified as good candidates for growth in PBRs.
Echoes of silence

Published: May 2024

AbstractCommunication is an integral part of nursing practice—with patients and their relatives, other nurses and members of the healthcare team, and ancillary staff. Through interaction with the ‘other’, language and silence creates and recreates social realities. Acceptance, rejection or modification of social realities depends on what is expressed and by whom. Narratives that are offered can tell of some experiences and not others. Some nurses choose to be silent while others are silenced. In nursing situations recognising and allowing silence to speak is a challenging but uniquely personal experience that embraces reflection in and on experiences, practice and self as a person and a professional. If enabled and truly heard, silence can speak more loudly than the hubbub of daily practice, allowing us to collectively question and challenge inherent assumptions and biases as professionals, and as a profession. Through a microcosm of Newly Graduated Nurses' lived experiences of nursing situations and expressions of silence individuals' discomfort and private efforts to ascribe meaning to experiences are reflected on. Returning to silence is to return to a constant process of professional transformation that can enable ways of knowing and being that can reform our profession from within and enable us to cast off shackles that bind us to a shameful cultural underbelly.
Another nursing is possible: Ethics, political economies, and possibility in an uncertain world
Authors: Dillard‐Wright Jess 
Published: May 2024

AbstractOvertaxed by the realities laid bare in the pandemic, nursing has imminent decisions to make. The exigencies of pandemic times overextend a health care infrastructure already groaning under the weight of inequitable distribution of resources and care commodified for profit. We can choose to prioritise different values. Invoking philosopher of science Isbelle Stengers's manifesto for slow science, this is not the only nursing that is possible. With this paper, I pick up threads of nursing's historical ontology, drawing previous scholarship on the historical narratives nurses use to understand themselves. Peeling back nursing's myth to alternate points of origin allows me to consider alternate lines of flight, a speculative adventure in paths not taken but paths that exist nonetheless. I go on to examine what a collective ethic of nursing could be, when we make space for these alternate histories, considering the confluences and conflicts that enable nurses to care and those that inhibit them from doing so. The imperative for this lies in the central importance of the reproductive labour of nursing health care, which leads me to a critique of nursing's capitulation to the pressures of late stage capitalism. This is a problem with ethical and ontological implications both for nursing, and also for those who require nursing care, an imperative to think about the kinds of present/futures for health, care, and health care we might cocreate in collaboration and solidarity with the communities in which nurses are imbricated, shedding the trappings of neoliberalism. There is significant power in the vision and praxis of 28 million nurses and midwives worldwide. Our ethics can guide our imagination which can in turn create possibility. This kind of endeavour—that of dreams and imagination—leads us to what could be, if only we leap.

AbstractObjectiveThis study aims to evaluate food impaction on three‐dimensional (3D) printed models with periodontal ligament simulation.Materials and MethodsBased on a commercial typodont pair, 3D maxillary and mandibular models were created with no teeth and with tooth sockets that were 1 mm wider than the original ones from 24 to 27 or 34 to 37 for periodontal ligament simulation with vinyl polysiloxane impression material. In total, 35 pairs of 7 combinations, including maxillary/mandibular typodonts in occlusion with maxillary/mandibular 3D models with/without a distal gap of canines on 3D models (tooth 23 or 33) were mounted on hinge articulators and divided into seven groups (n = 5). Each sample experienced the same manual chewing simulation on a customized device. The proximal surfaces were photographed to measure the percentage of food impaction area using ImageJ software.ResultsGroup with fixed maxillary and mandibular teeth showed more food impaction than other groups with significant differences in the average of maxilla and the average of all proximal areas.ConclusionThe flexibility of the periodontal ligament and the degree of freedom of the teeth in their sockets may contribute to the extent of food impaction in proximal spaces.

AbstractUltraviolet‐C (UVC) irradiation is being used as an effective approach for the disinfection of pathogenic viruses present in air, surfaces, and water. Recently, far‐UVC radiation (222 nm) emitted by KrCl* (krypton‐chloride) excimer lamps have been recommended for disinfecting high‐risk public spaces to reduce the presence and transmission of infectious viruses owing to limited human health exposure risks as compared to germicidal UVC (254 nm). In this study, the UVC inactivation performances of individual filtered KrCl* excimer lamp (222 nm) and germicidal UVC lamp (254 nm) were determined against four viruses, bacteriophages MS2, Phi6, M13, and T4, having different genome compositions (ssRNA, dsRNA, ssDNA and dsDNA, respectively) and shapes (i.e., spherical (Phi6), linear (M13), and icosahedral (MS2 and T4)). Here, the disinfection efficacies of filtered KrCl* excimer lamp (222 nm) and germicidal UVC lamp (254 nm) were evaluated for highly concentrated virus droplets that mimic the virus‐laden droplets released from the infected person and deposited on surfaces as fomites. Filtered KrCl* excimer (222 nm) showed significantly better inactivation against all viruses having different genome compositions and structures compared to germicidal UVC (254 nm). The obtained sensitivity against the filtered KrCl* excimer (222 nm) was found to be in the order, T4 > M13 > Phi6 > MS2 whereas for the germicidal UVC (254 nm) it was T4 > M13 > MS2 > Phi6. These results provide a strong basis to promote the use of filtered KrCl* excimer lamps (222 nm) in disinfecting contagious viruses and to limit the associated disease spread in public places and other high‐risk areas.

Published: May 2024

AbstractCaulerpa is a marine green macroalga distinguished by a large single cell with multiple nuclei. It also exhibits remarkable morphological intraspecies variations, in response to diverse environmental types. However, the molecular mechanisms underlying this phenotypic plasticity remain poorly understood. In this work, we compare the transcriptomes of Caulerpa okamurae Weber Bosse, 1897 displaying altered phenotypes of cultivation and natural phenotypes and investigate significantly regulated genes and their biological functions using differential expression analyses. We observe light‐harvesting complex upregulation and cellular framework stability downregulation in altered phenotypes compared to the natural phenotypes. Intertidal macrophytes reduce light capture to avoid photodamage and regulate their morphology to protect against wave damage. In contrast, the lower light conditions and the cultivation environment augment light capture and increase a morphology prioritizing light trapping. Moreover, the addition of simulated wave‐sweeping stimuli induces a return to the natural morphology under high‐light conditions, showing how mechanical stress affects morphological organization in C. okamurae. We provide detailed gene expression patterns in C. okamurae under varying light intensities and water conditions, suggesting a distinct influence on its morphological traits.
Cross‐sectional associations between temporal patterns and composition of upright and stepping events with physical function in midlife: Insights from the 1970 British Cohort Study

Published: May 2024

AbstractIntroductionAge‐related decline in physical functioning has significant implications for health in later life but declines begin earlier in midlife. Physical activity (PA) volume is associated with physical function, but the importance of the pattern in which PA is accumulated is unclear. This study investigates associations between patterns of PA accumulation, including the composition, variation, and temporal distribution of upright and stepping events, with physical function in midlife.MethodsParticipants (n = 4378) from the 1970 British Cohort Study wore an activPAL3 accelerometer on the thigh for 7 consecutive days. Exposure measures included a suite of metrics describing the frequency, duration, and composition of upright events, as well as the duration and volume (total steps) of stepping events. In addition, patterns of accumulation of upright and sedentary events were examined including how fragmented/transient they were (upright‐to‐sedentary transition probability [USTP]) and their burstiness (the tendency for events to be clustered together followed by longer interevent times). Physical function outcomes included grip strength (GS), balance, and SF‐36 physical functioning subscale (SF‐36pf). Cross‐sectional analyses included multivariable linear regression models to assess associations, adjusting for covariates including overall PA volume (mean daily step count).ResultsHigher upright event burstiness was associated with higher GS, and higher USTP was associated with lower GS. Duration and step volume of stepping events were positively associated with SF‐36pf in females. Step‐weighted cadence was positively associated with SF‐36pf and balance. Contradictory findings were also present (e.g., more transient stepping events were associated with better GS) particularly for GS in males. Inconsistencies between sexes were observed across some associations.ConclusionOur study reveals that diverse patterns of PA accumulation exhibit distinct associations with various measures of physical function in midlife, irrespective of the overall volume. Contradictory findings and inconsistency between sexes warrant further investigation. Patterns of PA accumulation, in addition to volume, should be considered in future PA research. Longitudinal studies are required to determine whether a given volume of activity accumulated in different patterns, impacts associations between PA and health outcomes.
Ironic processes of concentration and suppression under pressure: A study on rifle shooting in Norwegian elite biathletes

Published: May 2024

AbstractIn rifle shooting, suppressing unwanted thoughts can backfire in one's performance, causing athletes to behave contrary to their desired intention and further deteriorate their performance.PurposeThis study examined how priming attentional and negative cues affected participants' shooting performances toward ironic error targets under cognitive load conditions in Stroop task across two experiments.MethodsSemi‐elite biathletes (Experiment 1, n = 10; Experiment 2, n = 9) participated in the study. The study used a within‐subject quasi‐experimental design, particularly a one‐way repeated measures multivariate analysis of variance and a 2 × 2 fully repeated measures analysis of variance, to determine the participants' hit rates and shooting response times (RTs). In both experiments, the participants completed the reverse‐Stroop‐based target shooting performance under low‐ and high‐cognitive load conditions while receiving frequent priming attentional and negative cues.ResultsThe findings from Experiment 1 suggest that regulating repetitive priming attentional thoughts is efficacious in mitigating the likelihood of ironic performance errors and interference effects. The results of Experiment 2 show that repetitive priming negative cues resulted in negligible ironic error hit rates and slower RTs in target hits under high‐cognitive load conditions. The Bayesian analyses provided evidence supporting the null hypotheses.ConclusionTrying to control repetitive priming attentional and negative thoughts reduces ironic performance errors to a similar degree under cognitive load conditions among biathletes, regardless of interference effects. Further research is needed to determine the effectiveness of suppressing task‐relevant negative instructions in reducing the likelihood of ironic performance errors under pressure.
Critique and expansion of conceptions of control

Published: May 2024

AbstractNeil Fligstein's Conceptions of control have multiple theoretical origins in the institutional, political, and cultural perspectives of the new economic sociology. However, conceptions of control as a key concept of market structure have not systematically been formulated in Fligstein's works, remaining insightfully but relatively fragmentally. This paper summarizes the normative, power, and cognitive dimensions of conceptions of control, respectively corresponding to market agreement, dominant relationship and common understanding. On this basis, this paper provides a clear definition of conceptions of control. Additionally, this paper summarizes the formation of the conceptions of control and its change, distinguishes the differences between conceptions of control and other related concepts, and presents the evolution of the concept that has taken place in subsequent studies, as well as the criticisms to which it has been subjected. This paper suggests that this concept needs to be expanded in terms of the connotation of market actors, the role of government, and the forms of existence. Conceptions of control provide a concise conceptual tool for analyzing market transformation. We believe that the market changes triggered by the new business formats in the digital economy era will be more frequent, and conception of control will have a broader application prospect.
The organic carbon‐to‐clay ratio as an indicator of soil structure vulnerability, a metric focused on the condition of soil structure

Published: May 2024

AbstractThe soil organic carbon to clay ratio (SOC:clay) is a metric used in soil quality management. In Switzerland and the United Kingdom, for example, threshold values for SOC:clay ratios have been determined to indicate very good (>1:8) to degraded (<1:13) soil structures. A recent article in Soil Use and Management by Poeplau and Don, however, suggested that this metric is ‘strongly biased and misleading’, based on their observation that German sandy soils and heavy clay soils tend to show very high and very low SOC:clay ratios, respectively. An alternative metric was proposed based on the ratio of actual SOC to expected SOC level for a considered area. We offer a commentary on the proposal, arguing that because soil structure quality is overlooked by the approach, it fails to provide appropriate SOC levels for soil health and could lead to soils with highly depleted SOC being classified ‘good’. The SOC:clay ratio, on the other hand, does address soil structure condition, providing a structure vulnerability index, a key function independent of local soil management conditions. When soils are found to have high structure vulnerability, as indicated by the SOC:clay ratio, the cropping practices at the site should be investigated and ways to increase the SOC content considered. Structure condition threshold values may only need to be reassessed if it is shown that the average structure quality observed is not in conformity with the present thresholds, which would be expected for some soils, such as Andosols.

AbstractObjectiveMathematical models are vital tools to understand transmission dynamics and assess the impact of interventions to mitigate COVID‐19. However, historically, their use in Africa has been limited. In this scoping review, we assess how mathematical models were used to study COVID‐19 vaccination to potentially inform pandemic planning and response in Africa.MethodsWe searched six electronic databases: MEDLINE, Embase, Web of Science, Global Health, MathSciNet and Africa‐Wide NiPAD, using keywords to identify articles focused on the use of mathematical modelling studies of COVID‐19 vaccination in Africa that were published as of October 2022. We extracted the details on the country, author affiliation, characteristics of models, policy intent and heterogeneity factors. We assessed quality using 21‐point scale criteria on model characteristics and content of the studies.ResultsThe literature search yielded 462 articles, of which 32 were included based on the eligibility criteria. Nineteen (59%) studies had a first author affiliated with an African country. Of the 32 included studies, 30 (94%) were compartmental models. By country, most studies were about or included South Africa (n = 12, 37%), followed by Morocco (n = 6, 19%) and Ethiopia (n = 5, 16%). Most studies (n = 19, 59%) assessed the impact of increasing vaccination coverage on COVID‐19 burden. Half (n = 16, 50%) had policy intent: prioritising or selecting interventions, pandemic planning and response, vaccine distribution and optimisation strategies and understanding transmission dynamics of COVID‐19. Fourteen studies (44%) were of medium quality and eight (25%) were of high quality.ConclusionsWhile decision‐makers could draw vital insights from the evidence generated from mathematical modelling to inform policy, we found that there was limited use of such models exploring vaccination impacts for COVID‐19 in Africa. The disparity can be addressed by scaling up mathematical modelling training, increasing collaborative opportunities between modellers and policymakers, and increasing access to funding.
