The COVID-19 pandemic is a disaster event. Exposure to stressors during and after disaster events is associated with negative mental health symptoms. To inform targeted COVID-19 recovery efforts, data are needed to understand which stressors play a key role in this relationship.
Methods
Cross-sectional survey data (demographics, impacts of COVID-19, social determinants of health, depression, and anxiety) were collected online from adults living in New York state between May and June 2020. Differences in the proportion of stressors (COVID-19 and social determinants) experienced by race/ethnicity were assessed using chi-square analyses. Logistic regression was used to assess which factors were associated with increased odds of depression and anxiety.
Results
A majority (n = 258, 62.2%) of the 415 respondents reported being directly impacted by the pandemic. Non-white respondents reported a significantly larger proportion of stressors compared to white respondents. Under half of respondents reported depression (n = 171, 41.2%) and anxiety (n = 164, 39.5%). Healthcare and food concerns were associated with increased odds of depression and anxiety, and economic concerns were associated with increased odds of anxiety.
Conclusions
Findings underscore the need to respond to the COVID-19 mental health crisis by addressing social determinants of health.
The authors critique the NY Declaration on Animal Consciousness, which does not denounce continued captivity and invasive research in the pursuit of animal consciousness markers. They argue that such research often increases animal suffering by accepting harmful practices. Instead, they propose a nonanthropocentric, ethical framework aligned with the Belmont Report’s principle of beneficence, advocating for noninvasive methods in natural habitats. This approach prioritizes animal well-being, recognizing and safeguarding the intrinsic value of all conscious beings.
The spectrum and orthogonal eigenbasis are computed of a tridiagonal matrix encoding a finite-dimensional reduction of the difference Lamé equation at the single-gap integral value of the coupling parameter. This entails the exact solution, in terms of single-gap difference Lamé wave functions, for the spectral problem of a corresponding open inhomogeneous isotropic $XY$ chain with coupling constants built from elliptic integers.
Petrographical and geochemical data from the Togo structural unit (TSU), also referred to as the Atacora structural unit, are presented together with the existing dataset; geochemical and age data from the sedimentary and metasedimentary rocks from the passive margin sequences of the Dahomeyide belt in Ghana to infer their provenance and depositional setting and expand the discussion on the Rodina–Gondwana supercontinent assembly during the Pan-African orogeny. The metasedimentary rocks of the TSU are quartzites and phyllites. The framework grains of the quartzites consisting dominantly of quartz and small amounts of feldspar grains and relict lithic fragments classify them as quartz arenite, subarkose and sublitharenite. Generally, the studied rocks show similar rare-earth element and multi-element patterns, which imply derivation from similar sources. Elemental ratios, including (La/Lu)N, Th/Sc and La/Sc, suggest sediments sourced from intermediate to felsic rocks. Provenance and depositional setting indicators of the TSU suggest deposition in a passive margin setting, with the West African and Amazonian cratons’ granitoids and granitic gneisses as possible provenance, akin to siliciclastic rocks of the Buem structural unit and the Voltaian Supergroup of the Volta Basin. The deformational history of the TSU is similar to those of the Buem structural unit and the eastern margin of the Voltaian Supergroup, indicating the effect of the Pan-African orogeny on the passive margin of the Dahomeyide belt. We, therefore, propose the formation and evolution of a Neoproterozoic passive margin unit, which was tectonically deformed during the Rodinia–Gondwana supercontinent cycle.
I am a cinematic being of the Anthropocene. As a concerned citizen and environmental educator, I immerse myself in film. Gummo is a 1997 film by Harmony Korine that deeply resonates with me as a testament to the capacity and desire for humanity to realise the potential to rise from the epochal fall of the Anthropocene. I propose that my relationship with Gummo as arche-cinema is not just a process of watching and interpreting Korine’s cinematic world, but also (re)projecting my dreams of a new reality for the whole-Earth ecosystem onto the world-out-there. I suggest that my entanglement with Gummo exemplifies my climating and becoming-climate as film in our current human-induced climate crises, and in this way, I argue that I am learning to live-with climate change through film.
FOLD-RM is an explainable machine learning classification algorithm that uses training data to create a set of classification rules. In this paper, we introduce CON-FOLD which extends FOLD-RM in several ways. CON-FOLD assigns probability-based confidence scores to rules learned for a classification task. This allows users to know how confident they should be in a prediction made by the model. We present a confidence-based pruning algorithm that uses the unique structure of FOLD-RM rules to efficiently prune rules and prevent overfitting. Furthermore, CON-FOLD enables the user to provide preexisting knowledge in the form of logic program rules that are either (fixed) background knowledge or (modifiable) initial rule candidates. The paper describes our method in detail and reports on practical experiments. We demonstrate the performance of the algorithm on benchmark datasets from the UCI Machine Learning Repository. For that, we introduce a new metric, Inverse Brier Score, to evaluate the accuracy of the produced confidence scores. Finally, we apply this extension to a real-world example that requires explainability: marking of student responses to a short answer question from the Australian Physics Olympiad.
Childhood maltreatment and peer victimisation are common sources of early-life interpersonal stress. Childhood maltreatment is associated with atypical frontolimbic emotion processing and regulation, and increased vulnerability for self-harm/suicide. However, few studies have compared the neurofunctional correlates between caregiver- versus peer-inflicted mistreatment.
Aims
We compared the alterations of neurofunctional correlates of facial emotion processing in youths exposed to childhood maltreatment or peer victimisation, and explored their associations with self-harm.
Method
Functional magnetic resonance imaging data were collected from 114 age- and gender-matched youths (39 childhood maltreatment, 37 peer victimisation and 38 controls) during an emotion discrimination task. Region-of-interest (amygdala, insula) and whole-brain analyses were conducted.
Results
Groups differed significantly during disgust processing only. Both groups had lower activation in the right amygdala and bilateral posterior insula than controls; left insular underactivation was furthermore related to increased self-harm in maltreated youths. Compared with controls, at the whole-brain level, both groups also had underactivation in a cluster of bilateral limbic-thalamic-striatal, precuneus/posterior cingulate, temporal, fusiform/lingual and cerebellar regions, which was negatively associated with emotional problems in controls, as well as a cluster of somatosensory regions associated with increased self-harm in maltreated youths.
Conclusions
Early-life interpersonal stress from caregivers or peers is associated with common underactivation of limbic-thalamic-striatal, precuneus/posterior cingulate and somatosensory regions during disgust processing. The hypoactivation of key emotion and sensory processing and self-referential brain regions could be a potential suppressive mechanism to cope with the aversive emotion; however, it may also entail increased risk of affective psychopathology in seemingly healthy youths.
The revolution in Western family law over the past 50 years—often described as ‘liberalization’—involves a decrease in the importance of fault-based factors alongside an increase in the significance of marital contracts. While these two trends generally complement each other, they may conflict when a couple seeks to assign economic consequences to sexual fault through a contract. Should such an agreement be legally enforceable? Which aligns more with a ‘true liberal’ perspective: advocating against fault or for the use of contracts? This paper suggests a new approach that goes beyond simply determining which trend should prevail. We illustrate how the perceived conflict between proponents of sexual liberalization and proponents of contractual liberalization could be resolved by identifying the underlying reasons that motivate each ‘camp’, proposing potential legal mechanisms and specific legal contexts in which broad agreement might be reached, and explicating the multidimensionality of family law liberalization.
The ongoing deceleration of Whillans Ice Stream, West Antarctica, provides an opportunity to investigate the co-evolution of ice-shelf pinning points and ice-stream flux variability. Here, we construct and analyze a 20-year multi-mission satellite altimetry record of dynamic ice surface-elevation change (dh/dt) in the grounded region encompassing lower Whillans Ice Stream and Crary Ice Rise, a major pinning point of Ross Ice Shelf. We developed a new method for generating multi-mission time series that reduces spatial bias and implemented this method with altimetry data from the Ice, Cloud, and land Elevation Satellite (ICESat; 2003–09), CryoSat-2 (2010–present), and ICESat-2 (2018–present) altimetry missions. We then used the dh/dt time series to identify persistent patterns of surface-elevation change and evaluate regional mass balance. Our results suggest a persistent anomalous reduction in ice thickness and effective backstress in the peninsula connecting Whillans Ice Plain to Crary Ice Rise. The multi-decadal observational record of pinning-point mass redistribution and grounding zone retreat presented in this study highlights the on-going reorganization of the southern Ross Ice Shelf embayment buttressing regime in response to ice-stream deceleration.
We revisit Haiman’s conjecture on the relations between characters of Kazdhan–Lusztig basis elements of the Hecke algebra over $S_n$. The conjecture asserts that, for purposes of character evaluation, any Kazhdan–Lusztig basis element is reducible to a sum of the simplest possible ones (those associated to so-called codominant permutations). When the basis element is associated to a smooth permutation, we are able to give a geometric proof of this conjecture. On the other hand, if the permutation is singular, we provide a counterexample.
Following the application of MCPA/MCPB at 1.7 kg ae ha−1 at a field site near Dresden, ON, Canada, poor control (<50% visible control) of green pigweed (Amaranthus powellii S. Watson) was observed. Amaranthus powellii is a common weed in Ontario crop production, and its evolution of resistance to synthetic auxin herbicides (SAHs) could pose a risk to crop yields. The suspected resistant A. powellii population (R) was used in dose–response and field experiments to determine resistance to SAHs. The objective of these studies was to determine whether this population of A. powellii is resistant to MCPA and cross-resistant to other SAHs. The GR50 (herbicide dose that causes a 50% reduction in plant aboveground biomass) values were determined by fitting plant dry weight data, obtained following application with seven SAHs, to a four-parameter log-logistic equation and were compared between the suspected-resistant (R) population and a known susceptible (S) population of A. powellii. The field trial was conducted in 2017, 2018, 2019, and 2021 in corn (Zea mays L.) and consisted of 11 postemergence SAH treatments. The GR50 values differed between the R and S populations following application with MCPA, aminocyclopyrachlor, dichlorprop-p, and mecoprop, resulting in resistance factors of 4.4, 3.0, 2.5, and 2.4, respectively. In the field study, dicamba and MCPA ester controlled A. powellii 84% and 30%, respectively, at 8 wk after treatment application (WAA). The control of Amaranthus powellii with all SAHs applied POST in corn was poor (<90% visible control) at 8 WAA. Both studies confirmed resistance to SAHs in this population of A. powellii, which will create limitations for farmers aiming to control this weed.
We provide empirical evidence that the impact of quantitative easing (QE) programs on investment is weaker for countries with high-credit market regulations. We then extend a simple DSGE model with segmented financial markets to include credit regulation and examine its impact on the transmission of conventional and unconventional monetary policies. In our model, the government requires banks to hold a fraction of their assets in government debt. We show that the presence of such regulation can invert monetary transmission under QE policy: An expansionary QE program raises term premiums on corporate bonds and causes a contraction instead of an expansion in the economy. Such a perversion is absent under conventional policy. Further, in contrast to Carlstrom et al. (2017), we show that a simple Taylor rule welfare dominates a term premium peg under financial shocks, while the peg does better in the case of non-financial shocks.
Rinsing only with water or washing with soap and water are common methods of skin decontamination for skin contaminated during a chemical hazard release. The null hypothesis was that a 15-minute water irrigation (decontamination method 1) would not be superior to decontamination using a microfiber towel, followed by a wet wipe (Signature Select Softly Flushable Tissue Better Living Brands LLC, Pleasanton, CA), followed by using another microfiber towel (decontamination method 2).
Methods
A simulated contaminant (Magic Fluorescent Glow Paint for Face and Body, iLC Shenzhen Fulimei Technology Co. LTD, Shenzhen, the People’s Republic of China) was applied to the dorsal skin of each subject’s forearms. Then, photographs of these subject’s skin were taken before and after decontamination of the simulated contaminant by using either decontamination method 1 or 2. Each of the subjects underwent both decontamination methods in separate trials, with each subject using one forearm for decontamination method 1 and their other forearm for decontamination method 2. Discrete points of contamination were quantified on the photographs that were taken with the skin illuminated by ambient visible light or ultraviolet light (395nm, Roceei ultraviolet flashlight, China).
Results
Under visible light, no residual contamination was seen by inspecting photographs taken after decontaminating with either method. Under ultraviolet light, less visible contamination was seen by inspecting photographs taken after decontaminating with method 1 than after decontaminating with method 2.
Conclusion
In this study, skin decontamination with water irrigation was superior to skin decontamination without water irrigation.
Much has been written on the constitutional overhaul in Israel, and the attendant constitutional crisis in the first nine months of 2023. Since October 7, however, with the breakout of the Israel-Gaza war, the overhaul was seemingly shelved. This Article seeks to connect both events, by comparing the legal-political response to the overhaul with the legal-political response to the war. It asks why, given the intensity of the protest movement generated by the overhaul, there was a dearth of protest activity after the war, even though both events implicated similar values, namely the rule of law and individual rights, championed by the protest movement. I argue that a central reason for the disparity cannot only be explained by the dynamics of war but also due to the tensions and complexities inherent in Israel’s self-professed constitutional identity as a Jewish and democratic state. In particular, I argue that anti-overhaul protests appealed to liberal universalist values to garner bipartisan support, with the effect of bypassing substantive issues such as the occupation of the Palestinian Territories and discrimination faced by Israeli Palestinians. This explains the lack of Arab participation in the protests, as many perceived them to be an internal Jewish Affair. Thus, when post-war repressive measures mostly affected Israeli Palestinians, the protest movement failed to rally in their support. Although anti-overhaul protests could have brought about greater liberal consolidation in Israel, the relative lack of post-war mobilization casts lingering doubts on the possibility of long-term consolidation of liberal values in Israel. Attempts to depoliticize the protests, while perhaps successful in warding off the overhaul, and though impressive on their own, have likely failed in instilling deeper, more resilient, liberal values in Israel.
Combining tradition and innovation, timber plays essential roles in building structures for architecture and engineering. Tree branching geometries and timber in its natural state often serve as sources of inspiration. However, the mechanical properties of naturally grown timber, inherently inconsistent and geometrically varied, remain insufficiently studied, particularly for construction and simulations. This knowledge gap perpetuates the prevalent use of straight, uniformly harvested timber while neglecting curved and bifurcated elements with smaller cross-sections.
This research investigates the potential of naturally grown timber in structural design, emphasizing the importance of understanding the natural characteristics and growth patterns of trees to optimize timber use. The developed methodology leverages noninvasive technologies, such as computerized tomography (CT), to precisely capture the geometrical and material properties of wood. These data sources are then integrated to visualize cross-sectional geometries and material properties, forming the basis for our analytical approach. Utilizing generalized scaled boundary isogeometric analysis, the methodology enhances the accuracy and efficiency of simulations, aligning structural design with natural growth principles. This approach not only fosters sustainable resource practices by promoting the use of major tree parts but also transforms discarded materials into valuable resources. The paper concludes with a demonstration of this methodology applied in a practical construction scenario.
Psychotic symptoms in adolescence are associated with social adversity and genetic risk for schizophrenia. This gene–environment interplay may be mediated by personality, which also develops during adolescence. We hypothesized that (i) personality development predicts later Psychosis Proneness Signs (PPS), and (ii) personality traits mediate the association between genetic risk for schizophrenia, social adversities, and psychosis.
Methods
A total of 784 individuals were selected within the IMAGEN cohort (Discovery Sample-DS: 526; Validation Sample-VS: 258); personality was assessed at baseline (13–15 years), follow-up-1 (FU1, 16–17 years), and FU2 (18–20 years). Latent growth curve models served to compute coefficients of individual change across 14 personality variables. A support vector machine algorithm employed these coefficients to predict PPS at FU3 (21–24 years). We computed mediation analyses, including personality-based predictions and self-reported bullying victimization as serial mediators along the pathway between polygenic risk score (PRS) for schizophrenia and FU3 PPS. We replicated the main findings also on 1132 adolescents recruited within the TRAILS cohort.
Results
Growth scores in neuroticism and openness predicted PPS with 65.6% balanced accuracy in the DS, and 69.5% in the VS Mediations revealed a significant positive direct effect of PRS on PPS (confidence interval [CI] 0.01–0.15), and an indirect effect, serially mediated by personality-based predictions and victimization (CI 0.006–0.01), replicated in the TRAILS cohort (CI 0.0004–0.004).
Conclusions
Adolescent personality changes may predate future experiences associated with psychosis susceptibility. PPS personality-based predictions mediate the relationship between PRS and victimization toward adult PPS, suggesting that gene–environment correlations proposed for psychosis are partly mediated by personality.
Surge capacity—the ability to acquire additional workers and resources during unexpected increases in service demand—is often perceived as a luxury. However, the COVID-19 pandemic necessitated an urgent expansion of surge capacity within health systems globally. Health systems in Bangladesh, Nepal, and Sri Lanka managed to scale up their capacities despite severely limited budgets. This study employs a mixed-methods approach, integrating qualitative interviews with quantitative data analysis, to propose a comprehensive framework for understanding Human Resources for Health (HRH) surge capacity from 2018 to 2021, termed ARRAS: Anticipate, Recruit, Retain, Adapt, Sustain. We present national-level data to demonstrate how each country was able to maintain their per capita health care workforce during the crisis. Interviews with key informants from each country reinforce the ARRAS framework. Quantitative data revealed ongoing increases in doctors and nurses pre- and post-pandemic, but no country could rapidly expand its health workforce during the crisis. Qualitative findings highlighted critical strategies such as pre-crisis planning, financial incentives, telemedicine, and re-skilling the workforce. Despite adaptive measures, challenges included inadequate funding, poor data systems, and coordination issues. This study underscores the necessity for robust, long-term strategies to enhance surge capacity and better prepare health systems for future crises.
Deformed wing virus (DWV), which is an important honey bee virus transmitted by Varroa destructor (V. destructor), causes colony losses in honey bee colonies. This study aimed to investigate the prevalence and genetic diversity of DWV in honey bees in Türkiye and to determine the role of V. destructor in the transmission of the genetic variants of DWV. Honey bee samples were collected from 62 apiaries, by simple random sampling, during March 2022 and April 2023. The presence of V. destructor in collected bee samples was examined using a stereo microscope. Real-time RT-PCR was used for the detection of DWV-A and DWV-B (Varroa destructor virus-1 (VDV-1)) viruses. Genetic characterisation of the positive samples was conducted by sequencing polyprotein genomic region. Considering the V. destructor infestation rate of 3% as relevant, out of the 62 apiaries examined, 17 (27.4%) were positive. However, DWV-A and VDV-1 specific RNA was not detected in V. destructor samples. VDV-1 specific RNA was detected in 6.5% (4/62) of the apiaries, whereas DWV-A was not detected in the sampled apiaries. Phylogenetic analysis showed that isolates detected in this study were located in a separate cluster from previously characterised DWV-A and VDV-1 isolates. According to RDP4 and GARD analyses, DWV-VDV-1 recombination breakpoints were detected in field isolates. To the best our knowledge, this is the first report of the presence of VDV-1-DWV recombinants in Türkiye. Further studies are needed to determine the impact of VDV-1-DWV recombinants and their virological and antigenic properties.
The need for more radical forms of learning-centred transformation is increasingly recognised in transformations to sustainability. Yet these approaches to learning remain under-developed and undertheorised especially from a politics and environmental education research perspective. This paper offers a review of an emerging politics of transgression in environmental education research, as developed through an extensive T-learning (transgressive learning in times of climate change) knowledge co-production research programme, spanning eight years, and continuing. The ongoing problem that the research programme seeks to address is how to do transgressive learning in/as environmental education research in times where the fall out of coloniality and fossil capital collide in an increasingly regressive political landscape which Akomolafe and Ladha (2017, pg. 820) describe as “the deadening ideology of late-stage capitalism and its corollaries of patriarchy, rationalism, white supremacy and anthropocentrism.” Through the paper, I seek to highlight a “low theory” (Wark, 2021) of transgressive politics in environmental education research, embodied in practices of transgressive politics as movement in co-engaged T-learning research, which I illuminate through a meta-reflective curational process from the ‘archive’ or T-learning knowledge commons collection.
