Significant Shift Research Articles

Value-Based Proposition of an Adapted Integrated Care Telehealth Service for Accountable Care Organization Members.

The authors describe a real-world application of virtually integrated primary and behavioral health care implemented within an accountable care organization (ACO) system. Cost-of-care data from before and after a 6-month intervention were analyzed for 121 Medicaid and Child Health Plan Plus ACO members. The intervention was associated with a significant shift in the distribution of health care costs, from inpatient and emergency care to outpatient and preventive care. The program demonstrates a flexible and replicable approach to integration that can help expand effective primary care.

Abstract 1609: Inferring the T cell repertoire dynamics in non-small cell lung cancer metastases

Abstract Non-small cell lung cancer (NSCLC) is a highly complex disease, characterized by extensive genomic heterogeneity and dynamic evolution under therapeutic pressure. This evolution can lead to alterations in the antigens expressed by cancer cells, thereby influencing the T cell repertoire (TCR) as T cells expand in response to foreign antigens. Despite the central role of TCR in cancer progression and treatment response, only few studies have investigated the temporal and spatial changes in the TCR repertoire. In this study, we delve into the role of the TCR repertoire in metastatic progression in NSCLC. We conducted TCR sequencing of multiregion primary tumors, normal-adjacent tissues, and post-mortem metastases sampled from a cohort of 22 patients enrolled in the TRACERx and PEACE studies. Our findings reveal that primary tumor regions and normal-adjacent tissues exhibit similar fractions of expanded clonotypes. However, a higher proportion of expanded intratumoral TCRs were privately expanded in the tumor samples, suggesting a unique TCR landscape within the tumor microenvironment. The TCR repertoire across multiregion primary tumor samples was largely homogenous, with most expanded clonotypes shared across at least two regions. However, only a small fraction of these clonotypes were tracked in metastases, indicating a significant shift in the TCR repertoire during metastatic progression. Notably, the expanded clonotypes that persisted over time from early to late stage disease were significantly enriched for clonotypes ubiquitously expanded in the primary tumor across all regions. This was not shown to be associated with an increased likelihood of generation via VDJ recombination, suggesting a tumor-specific immune response. The expanded TCR repertoire in the postmortem metastases clustered mainly by anatomical site, suggesting an immune response driven by tissue-resident T cells. Moreover, we found a significant positive correlation between repertoire dissimilarity and genomic distance, suggesting that T cell clones track with tumor clones across spatial sites within patients. Our study demonstrates the significant spatiotemporal dynamics of the TCR repertoire during the metastatic progression of NSCLC, orchestrated by both tissue-resident T cells and the genomic evolutionary trajectory of tumors. Such an exploration could provide valuable insights to inform future strategies for immunotherapy treatments and enhance clinical monitoring of patients.

Abstract 1712: Identifying a novel alternative promoter usage in HDAC9: Implications for LUAD prognosis and therapy

Abstract Promoters are key elements in gene regulation. It has been estimated that more than half of protein-coding genes in the human genome possess multiple promoters. Aberrant expression and dysregulated activity of alternative promoters have been correlated with numerous diseases, especially cancer. In this study, we utilized RNA-seq data from 608 lung adenocarcinoma (LUAD) patients and systematically analyzed promoter activities using the proActiv algorithm. Of the expressed genes in LUAD, approximately 57% have at least two distinct promoters. In addition, we identified 1852 tumor-specific alternative promoters that showed a significant shift (2-fold changes) in promoter activity without any notable changes in the expression of corresponding 1603 genes between tumor and adjacent non-tumor tissues. Functional enrichment analysis showed that these genes were associated with key cellular functions such as signaling pathways, cell cycle, and cell junctions. Unsupervised clustering of patients based on altered promoters revealed a significant prognostic value. Among them, we observed a major promoter switch in HDAC9, which mainly utilizes three promoters: prmt3280, prmt3283, and prmt3287 in our LUAD dataset. Notably, prmt3287 was exclusively active in tumor samples and functioned as the dominant promoter, while prmt3283 served as the main promoter in adjacent non-tumor samples. Intriguingly, even though the overall expression of HDAC9 mRNA lacked prognostic relevance both in our dataset and in the TCGA dataset, higher expression of the alternative promoter prmt3287 (using ≥50% activity level as a cutoff) was associated with adverse outcomes in LUAD patients. We further compared the DNA methylation level around the HDAC9 domain between paired tumor and non-tumor samples and found that positions with the most significant differences (p<0.001) overlapped with the prmt3287 region. Moreover, DNA methylation levels around prmt3287 significantly decreased in prmt3287 high-activity patient groups. Next, we investigated the ChIP-seq levels over the HDAC9 region, and ChIPseeker successfully annotated the alternative promoters of HDAC9. In addition, the alternative promoter prmt3287 exhibited the highest active enhancer signals. Furthermore, we performed PCR to determine the expression of six distinct transcript isoforms from alternative promoters in four different LUAD cell lines, and we observed high expression of isoform 10, which is possibly generated by prmt3287 in all cell lines. The impact of prmt3287 on cell proliferation, cell cycle, and cell migration will be further addressed. Our results indicate that alternative promoter usage can capture insights that might be missed at the overall gene expression level, and alternative promoter usage in HDAC9 could be a novel biomarker and a promising therapy target.

Temporal trends in prevalence and disability of chronic kidney disease caused by specific etiologies: an analysis of the Global Burden of Disease Study 2019.

The prevalence of disability in CKD is high. In this context the aim of the present study wasto assess the temporal trends of prevalence and disability progression for chronic kidney disease (CKD) caused by specific etiologies. Using data from the Global Burden of Diseases Study (GBD) 2019, we examined the age-standardized rates of CKD prevalence and disability-adjusted life-years for different etiologies, including Type 1/2 diabetes mellitus (T1DM/T2DM), glomerulonephritis, and hypertension. We also calculated the average annual percentage changes to assess trends. Additionally, we utilized the joinpoint regression model to identify significant shifts over time. From 1990 to 2019, the global prevalence of CKD due to various etiologies exhibited an overall increasing trend, albeit with fluctuations. Notably, CKD due to T1DM, glomerulonephritis, and hypertension consistently demonstrated a significant upward trend across all continents, while the prevalence of CKD due to T2DM varied across continents. In terms of disability-adjusted life-years, CKD due to T2DM and hypertension exhibited a significant rising trend over the past 30 years. However, changes in age standardized disability-adjusted life-years for CKD due to different etiologies were not consistent across continents, with an upward trend observed in The Americasand a contrasting trend in Asia. Furthermore, both age-standardized prevalence rate and age standardized disability-adjusted life-year trends for CKD varied significantly across 204 countries and territories. Additionally, a negative association was observed between the Socio-demographic Index and the disability progression of CKD. The prevalence and disability burden of CKD caused by specific etiologies show substantial heterogeneity worldwide, highlighting significant disparities in the distribution of CKD. It is crucial to implement geographic and personalized strategies in different regions to alleviate the burden of CKD effectively.

Colorimetric Pressure Sensing by Plasmonic Decoupling of Silver Nanoparticles Confined within Polymeric Nanoshells.

Employing a plasmonic decoupling mechanism, we report the design of a colorimetric pressure sensor that can respond to applied pressure with instant color changes. The sensor consists of a thin film of stacked uniform resorcinol-formaldehyde nanoshells with their inner surfaces functionalized with silver nanoparticles. Upon compression, the flexible polymer nanoshells expand laterally, inducing plasmonic decoupling between neighboring silver nanoparticles and a subsequent blue-shift. The initial color of the sensor is determined by the extent of plasmonic coupling, which can be controlled by tuning the interparticle distance through a seeded growth process. The sensing range can be conveniently customized by controlling the polymer shell thickness or incorporating hybrid nanoshells into various polymer matrices. The new colorimetric pressure sensors are easy to fabricate and highly versatile, allow for convenient tuning of the sensing range, and feature significant color shifts, holding great promise for a wide range of practical applications.

The Meloni government in the context of the ‘smaller’ parliament: new programmes, old equipment

ABSTRACT This article assesses, a few months after the Meloni government’s inauguration, the extent to which the new executive has as compared to its predecessors, been an executive of change. The significant shifts that had taken place in the political landscape gave rise to expectations of considerable innovation. The Meloni government is the first led by a woman; it marks the return of a centre-right majority coalition to power, and it operates within a parliament that is smaller due to the 2020 constitutional reform that reduced the number of deputies and senators. In light of these factors, we examine whether the Government’s actions are different compared to its predecessors based on the Prime Minister’s profile and the political and technical qualifications of ministers. We test our expectations by analysing the Government’s legislative activity, particularly focusing on the 2024 budget. However, the findings fail to support our expectations for the period under investigation, as long-term trends prevailed.

An Overview of Niosomes

In recent times, there has been a significant shift towards developing targeted biological substances for the treatment of infectious diseases and vaccination. Non-ionic surfactant vesicles, known as niosomes, have emerged as a distinctive vesicular structure in contemporary drug delivery methods due to their biological breakdown, compatibility, chemical resistance, cost-effectiveness, ease of manufacturing and preservation, and low toxicity. The progress in nanocarrier technology has garnered attention for its safety and associated advantages, including enhanced therapeutic administration with diverse pharmacological effects, improved targeting capabilities, and reduced side effects. Niosomes serve as vesicular carriers for drugs, composed of non-ionized surfactants, cholesterol or analogs, and charged molecules that enable controlled and targeted drug delivery. They are categorized as unilamellar, oligolamellar, or multilamellar structures. This comprehensive review article provides an overview of niosomes, covering their structure, types, formulation methods, characterization, advantages and disadvantages, preparation techniques, influencing factors, evaluation criteria, applications, and currently available formulations in the market.
 Keywords: Niosomes, drug delivery system, methods of Preparation, Applications.

Holistic Energy Awareness and Robustness for Intelligent Drones

Drones represent a significant technological shift at the convergence of on-demand cyber-physical systems and edge intelligence. However, realizing their full potential necessitates managing the limited energy resources carefully. Prior work looks at factors such as battery characteristics, intelligent edge sensing considerations, planning, and robustness in isolation. But a global view of energy awareness that considers these factors and looks at various tradeoffs is essential. To this end, we present results from our detailed empirical study of battery charge-discharge characteristics and the impact of altitude and lighting on edge inference accuracy. Our energy models, derived from these observations, predict energy usage while performing various manoeuvres with an error of 5.6%, a 2.5X improvement over the state-of-the-art. Furthermore, we propose a holistic energy-aware multi-drone scheduling system that decreases the energy consumed by 21.14% and the mission times by 46.91% over state-of-the-art baselines. To achieve system robustness in the event of link or drone failure, we observe trends in Packet Delivery Ratio to propose a methodology to establish reliable communication between nodes. We release an open-source implementation of our system. Finally, we tie all of these pieces together using a people-counting case study.

Engineering Quantum Light Sources with Flat Optics.

Quantum light sources are essential building blocks for many quantum technologies, enabling secure communication, powerful computing, and precise sensing and imaging. Recent advancements have witnessed a significant shift toward the utilization of "flat" optics with thickness at subwavelength scales for the development of quantum light sources. This approach offers notable advantages over conventional bulky counterparts, including compactness, scalability, and improved efficiency, along with added functionalities. This review focuses on the recent advances in leveraging flat optics to generate quantum light sources. Specifically, the generation of entangled photon pairs through spontaneous parametric down-conversion in nonlinear metasurfaces, and single photon emission from quantum emitters including quantum dots and color centers in 3D and 2D materials are explored. The review covers theoretical principles, fabrication techniques, and properties of these sources, with particular emphasis on the enhanced generation and engineering of quantum light sources using optical resonances supported by nanostructures. The diverse application range of these sources is discussed and the current challenges and perspectives in the field arehighlighted.

Integrative methods reveal multiple drivers of diversification in rice paddy snakes

Divergence dating analyses in systematics provide a framework to develop and test biogeographic hypotheses regarding speciation. However, as molecular datasets grow from multilocus to genomic, sample sizes decrease due to computational burdens, and the testing of fine-scale biogeographic hypotheses becomes difficult. In this study, we use coalescent demographic models to investigate the diversification of poorly known rice paddy snakes from Southeast Asia (Homalopsidae: Hypsiscopus), which have conflicting dates of origin based on previous studies. We use coalescent modeling to test the hypothesis that Hypsiscopus diversified 2.5 mya during the Khorat Plateau uplift in Thailand. Additionally, we use ecological niche analyses to identify potential differences in the niche space of the two most widely distributed species in the past and present. Our results suggest Hypsiscopus diversified ~ 2.4 mya, supporting that the Khorat Plateau may have initiated the diversification of rice paddy snakes. We also find significant niche differentiation and shifts between species of Hypsiscopus, indicating that environmental differences may have sustained differentiation of this genus after the Khorat Plateau uplift. Our study expands on the diversification history of snakes in Southeast Asia, and highlights how results from smaller multilocus datasets can be useful in developing and testing biogeographic hypotheses alongside genomic datasets.

Applying a Three-Tier Approach to Address Gaps in Oral Pre-Exposure Prophylaxis Uptake and Continuity in Uganda: A Mixed Methods Approach.

We describe a 3-tier approach involving a gap analysis, root cause analysis, and pre-exposure prophylaxis (PrEP) collaborative to understand the gap and identify and address the main barriers to oral PrEP uptake and continuity in Uganda. We used a mixed methods design with retrospective, cross-sectional, and prospective components. The gap analysis involved descriptive analysis of PrEP uptake and continuity. The RCA identified the main barriers to initiation and continuity on PrEP among 1,334 clients who declined to start PrEP and 1,266 who missed their appointment but were at risk. The PrEP collaborative tested changes mapped onto specific barriers to optimize the PrEP clinical service delivery. A trend analysis of routinely collected data of the PrEP cascade determined significant shifts and trends in PrEP uptake and continuity. Only 60% of the high-risk population eligible for PrEP were enrolled, while fewer than 30% of the cumulative number of PrEP users were refilled each quarter. Uncertainty and fear of side effects, perceptions about the harmfulness of the medication, perceived inability to adhere to PrEP, and stigma were the main reasons why clients rejected PrEP. Lack of access to the facility, side effects, pill burden, stigma, perceived low-risk exposure to HIV, and preference of staying at work as opposed to picking up refills affected continuity on PrEP. The collaborative registered statistically significant shifts in PrEP enrollment from 64% to 89% and continuity from 51% to 78% between July 21 and November 22 following the collaborative intervention. We recommend using a 3-tier approach for other similar implementation contexts to strengthen PrEP programming, given the marked statistical shift in PrEP uptake and continuity. This begins with understanding the gap and barriers to use among clients, followed by mapping interventions to specific barriers through a quality improvement collaborative.

From peak to plummet: impending decline of the warm Arctic-cold continents phenomenon

This study assesses the projected trajectory of Warm Arctic-Cold Continent (WACC) events in East Asia and North America through large ensemble simulation for the upcoming decades. It analyses the evolution of the geographical boundaries of threshold cold temperatures, revealing a significant northward shift as a sign of global warming’s impact on the southward advancement of Arctic cold air. While validating the intensification of the WACC phenomenon until the 2020 s, echoing earlier studies, the findings indicate a marked decrease beginning in the 2030s. If warming is not curbed, this shift suggests a critical modification in the WACC pattern, prompting a re-evaluation of existing theories and models for extreme winter weather events. The results have major implications, spurring communities impacted by WACC to anticipate future changes and encouraging the climate forecasting community to update conceptual models for improved adaptation and mitigation approaches.

Longitudinal Mapping of Personal Biotic and Abiotic Exposomes and Transcriptome in Underwater Confined Space Using Wearable Passive Samplers.

Silicone-based passive samplers, commonly paired with gas chromatography-mass spectrometry (GC-MS) analysis, are increasingly utilized for personal exposure assessments. However, its compatibility with the biotic exposome remains underexplored. In this study, we introduce the wearable silicone-based AirPie passive sampler, coupled with nontargeted liquid chromatography with high-resolution tandem mass spectrometry (LC-HRMS/MS), GC-HRMS, and metagenomic shotgun sequencing methods, offering a comprehensive view of personalized airborne biotic and abiotic exposomes. We applied the AirPie samplers to 19 participants in a unique deep underwater confined environment, annotating 4,390 chemical and 2,955 microbial exposures, integrated with corresponding transcriptomic data. We observed significant shifts in environmental exposure and gene expression upon entering this unique environment. We noted increased exposure to pollutants, such as benzenoids, polycyclic aromatic hydrocarbons (PAHs), opportunistic pathogens, and associated antibiotic-resistance genes (ARGs). Transcriptomic analyses revealed the activation of neurodegenerative disease-related pathways, mostly related to chemical exposure, and the repression of immune-related pathways, linked to both biological and chemical exposures. In summary, we provided a comprehensive, longitudinal exposome map of the unique environment and underscored the intricate linkages between external exposures and human health. We believe that the AirPie sampler and associated analytical methods will have broad applications in exposome and precision medicine.

INVESTIGATION THE IMPACT OF DIFFERENT ANNEALING TEMPERATURES ON STRUCTURAL AND OPTICAL PROPERTIES OF BI-DOPED GETE (BI: 5 %) THIN FILMS FABRICATED BY PVD TECHNIQUE)

The impact of different annealing temperatures on the Bi-doped GeTe thin films were investigated. The thin films have been prepared by using physical vapor deposition techniques (PVD). The Bismuth (Bi) is doped GeTe with ratio of 5%. Different characterizations techniques have been used to study the different properties of thin films with several annealing temperatures. It has been found that the film thickness decreases as the annealing temperature increases. The XRD patterns show that as-deposited and annealed Bi-doped GeTe films at 150°C,200°C, and 250°C were fully amorphous, while the film annealed at 100 °C was crystalline. FESEM image shows that the structure is amorphous with no grain appearing for the crystallite GeTe compound. Whereas the annealed thin films at 100°C are well-appeared crystallites of GeTe with an average size of (110.64 nm). The thin films are annealed at (150, 200, and 250)°C which reveals that the crystallite or grain is increased. An increase in the annealing temperature has been found to cause a significant shift in the absorption edge toward an extended wavelength and an overall reduction in transmittance. At a wavelength of 1100 nm, the transmittance dropped from 65.25% for as-deposited thin films to 32.57% for annealed thin films at 250 °C. Furthermore, when the annealing temperature rises from 100°C to 250°C, the optical band gap reduces from 0.95 eV to 0.42 eV.

Adaptability of Prunus cerasifera Ehrh. to Climate Changes in Multifunctional Landscape

Urban trees play a vital role in mitigating climate changes, maintaining the sustainability of ecosystems. This study focuses on the assessment of the resilience of cherry plums to climate changes, a fruit-bearing species that offers diverse ecosystem services within multifunctional urban and suburban landscapes. This study examines flowering and fruiting in the context of climate characteristics, expressed through the Day of the Year (DOY), Growing Degree Days (GDDs), and a yield over 17 consecutive years. The results indicate significant shifts in the DOY but not in the GDD, apart from the end of flowering. The onset of flowering was earlier and the end postponed, extending the phenophase by an average of 4 days. The cherry plum’s yield was unaffected by climate changes, including extreme events like a late-spring frost. The stability of the cherry plum was confirmed by the phenological patterns of the bullace (cherry plum and blackthorn hybrid) exhibiting repeated flowering in the warmest year of 2023. The cherry plum is an adaptive species, with a high adaptability to a changing climate and a high resistance to late-spring frosts; thus, it is a favorable choice in urban design and planning, demonstrating resilience to climate shifts and thriving in polluted urban environments. It is especially appreciated for multiple ecosystem services: biodiversity conservation in natural and semi-natural areas, yielding good provisions in challenging environments, and the preservation of ornamental values through an extended flowering phenophase.

Improved Alcohol Oxidation through Combined Effects of Tensile Lattice Strain and Twin Defects in Core-Shell Electrocatalysts.

The direct alcohol fuel cells (DAFCs) rely on alcohol oxidation reactions (AORs) to produce electricity, which require catalysts with optimized electronic structure to accelerate the sluggish AORs. Herein, an epitaxial growth of Pd layer onto the pentatwinned Au@Ag core-shell nanorods (NRs) is reported to synthesize highly strained Au@AgPd core-shell NRs. The tensile strain in the AgPd shell of the Au@AgPd nanorods (NRs) arises not only from the core-shell lattice mismatch but also from twinning and lattice distortion occurring at the five twinned boundaries present in the structure. Theoretical simulations prove that the presence of tensile strains in the AgPd layer leads to a significant upward shift of the d-band center of the Pd site toward the Fermi level which remarkably changes the adsorption energy of alcohols on the surface. Highly strained Au@AgPd NRs show exceptional mass activities in electrochemical oxidation of biomass-derived alcohols (ethylene glycol, ethanol, and glycerol) reaching up to 18.66, 15.6, and 7.90 A mgpd -1 , respectively. These values are 23.3, 23.6, and 23.2 times higher than commercial Pd/C catalysts. This strain engineering strategy set the platform for the design and synthesis of highly efficient and versatile catalysts for the construction of high-performance DAFCs.

AI in Education 2023

The integration of artificial intelligence (AI) tools in education has emerged as a significant paradigm shift. As we navigate this new landscape, it is essential to understand the adoption and use of these technologies in educational settings. Some valuable insights into AI's global trends and potential in education are available from OECD-Education International (2023), highlighting a need to understand privacy concerns and equitable access. Guidelines and advice have also been made available for New Zealand schools from the Ministry of Education (2024). However, there currently needs to be more comprehensive studies of AI in education that focus on the specific context of Aotearoa, New Zealand. This report seeks to meet that need. Educators from throughout Aotearoa were invited to participate in a survey conducted between August and November 2023. The survey aimed to assess the landscape of AI implementation in schools, exploring practices, challenges, and potential positive outcomes associated with AI tools in education. This research seeks to inform policymakers, educators, and stakeholders to facilitate informed decision-making to advance educational practices. Through this research, we hope to contribute to the ongoing dialogue on AI in education and its implications for teaching and learning in Aotearoa.

Mental and Physical Symptoms and Perceived Health Risks of Pregnant and Postpartum Women following the Significant Shift in COVID-19 Management in China: A Cross-Sectional Survey

Background. There was a remarkable downgrade in China’s COVID-19 response strategies in January 2023. The COVID-19 infection rate grew rapidly in the early stages following the management policy shift. This study attempted to explore the associations between SARS-CoV-2 infection and mental or physical health status in pregnant and postpartum women and the role of perceived health risks and family members’ SARS-CoV-2 infection status on these associations by capturing the impact of policy shifts in a short period of time. Methods. This cross-sectional study with a random sample from a convenience sample of hospitals was conducted in pregnant and postpartum women in January 2023. Standardized assessment tools were employed to assess anxiety, depressive and physical symptoms, and feelings of hopelessness. Hierarchical multiple logistic regressions were conducted to examine the mechanisms of associations of interests by including a range of sociodemographic factors, self-perceived health, SARS-CoV-2 infection status, and perceived health risks as covariates. Results. Of the 1,013 pregnant and postpartum women aged 32.0 ± 0.3 years, 58.2% (n = 590) were diagnosed with COVID-19, and 49.4% (n = 500) had family members who were infected with SARS-CoV-2. Nearly 98% of the included participants took measures to prevent SARS-CoV-2 infection. A COVID-19 diagnosis was positively associated with feelings of hopelessness (OR = 1.68, 95% CI: 1.20–2.35), probable anxiety (OR = 6.42, 95% CI: 2.18–24.61), possible depression (OR = 2.56, 95% CI: 1.07–6.70), and physical symptoms (OR = 6.28, 95% CI: 1.63–42.03) after adjusting for sociodemographic and health characteristics, while the associations presented no statistical significance when family members’ SARS-CoV-2 infection status and perceived health risks were introduced into the models. Conclusions. Our results suggested that pregnant and postpartum women may experience physical and mental health challenges when they or their family members contracted COVID-19 in the context of a considerable shift in COVID-19 management. Early detection of poor health status and its risk factors for vulnerable groups during shifts in health policy and administrative practice is very necessary, and health services, including easy access to psychosocial support and obstetric counselling, should be prioritized.

Evolutionary Trends of Polygenic Scores in European Populations From the Paleolithic to Modern Times.

This study examines the temporal and geographical evolution of polygenic scores (PGSs) across cognitive measures (Educational Attainment [EA], Intelligence Quotient [IQ]), Socioeconomic Status (SES), and psychiatric conditions (Autism Spectrum Disorder [ASD], schizophrenia [SCZ]) in various populations. Our findings indicate positive directional selection for EA, IQ, and SES traits over the past 12,000 years. Schizophrenia and autism, while similar, showed different temporal patterns, aligning with theories suggesting they are psychological opposites. We observed a decline in PGS for neuroticism and depression, likely due to their genetic correlations and pleiotropic effects on intelligence. Significant PGS shifts from the Upper Paleolithic to the Neolithic periods suggest lifestyle and cognitive demand changes, particularly during the Neolithic Revolution. The study supports a mild hypothesis of Gregory Clark's model, showing a noticeable rise in genetic propensities for intelligence, academic achievement and professional status across Europe from the Middle Ages to the present. While latitude strongly influenced height, its impact on schizophrenia and autism was smaller and varied. Contrary to the cold winters theory, the study found no significant correlation between latitude and intelligence.
