Customizable and adaptable middleware of things

SummaryMiddleware has become an essential element in the construction of distributed Internet of Things (IoT) applications. While it plays a central role in hiding the complexities of distribution, middleware systems have also been responsible for dealing with the uncertainties in IoT environments, such as changes during operation (e.g., inaccuracies in sensor data collection) and fluctuations in resource availability, for example, the battery. These uncertainties demand attention as they can result in application failures or, even worse, jeopardize the safety of applications. Existing middleware systems are being enhanced with self‐adaptive capabilities to address these uncertainties. It means they can make runtime adjustments to the middleware and applications (built atop them) without complete shutdowns. Despite the variety of available adaptive solutions, IoT applications often face uncertainties, each requiring a distinct adaptive action. For instance, the need to fine‐tune a thing's workload due to battery consumption is a common challenge. Furthermore, these applications are susceptible to changes occurring at various layers, presenting a complex challenge of managing them simultaneously. This paper introduces Middleware Extendify (MEx), a solution for building and executing IoT adaptive middleware systems. MEx simplifies the implementation of middleware and provides an underlying environment that executes the middleware and supports a range of adaptation mechanisms. This approach ensures that the middleware meets the evolving demands of applications and copes with changes at runtime. The evaluation of MEx encompasses different adaptive middleware implementations to measure the impact of the proposed adaptation mechanisms. The results indicate that adaptation comes with acceptable performance costs while offering the ability to fine‐tune middleware functionality or align IoT applications more effectively.

THE USE OF INTERVIEWS IN RESEARCH ON BELIEFS IN THE TEACHING-LEARNING OF LANGUAGES DURING INITIAL TEACHER EDUCATION

We investigated the use of interviews as an instrument to produce data in studies about beliefs in the teaching and learning of foreign languages during the initial teacher education of student teachers in bachelor's of education degrees with a major in a foreign language. We intended to assist the process of conducting interviews related to this topic. We conducted bibliographic research and reported our experience in preparing and applying the tool. We used as theoretical framework authors such as Manzini (2003), Gerhardt et al. (2009), and Edwards and Holland (2013), among others. Five questions guided our investigation: 1) What are the advantages of using interviews in research on beliefs? 2) What are the disadvantages of using interviews in research on beliefs? 3) What type(s) of interviews is/are more appropriate for research on beliefs? 4) How should interviews be planned for research on beliefs? 5) How can we conduct interviews in research on beliefs? The results indicated that interviews could successfully be used in investigations about the subject through proper planning and use of the instrument. It is a complex task that demands effort and attention from researchers.

Using Virtual Reality to Enhance Forensic Science Education: Effects on CSI Learning Achievements, Situational Interest and Cognitive Load

This study examined the effectiveness of an interactive VR-based platform (IVR-CSI) for crime scene investigation training in forensic science education. The IVR-CSI utilized real-case scenarios and head-mounted displays. University students majoring in criminal investigation (N = 71) participated, with 36 using IVR-CSI and 35 in the control group with traditional training. Pre-test, post-test, and delayed test assessments to measure learning achievements, situational interest, and cognitive load. Statistical analysis revealed that the experimental group demonstrated significantly better immediate learning outcomes and retained knowledge more effectively over time compared to the control group. The IVR-CSI also elicited higher situational interest across most dimensions, particularly in novelty, exploration intention, attention demand, and instant enjoyment. Importantly, IVR-CSI did not increase students’ intrinsic and extraneous cognitive load but enhanced their germane cognitive load. These results highlight the positive impact of IVR-CSI on CSI training, offering valuable insights for enhancing professional training programs and instructional methods in this field.

Developmental differences in striatal recruitment by reward prospects as a function of attentional demand

Adolescent risk-taking has been attributed to earlier-developing motivational neurocircuitry that is poorly controlled by immature executive-control neurocircuitry. Functional magnetic resonance imaging findings of increased ventral striatum (VS) recruitment by reward prospects in adolescents compared to adults support this theory. Other studies found blunted VS recruitment by reward-predictive cues in adolescents compared to adults. Task features may explain this discrepancy but have never been systematically explored. Adolescents and adults performed a novel reward task that holds constant the expected value of all rewards but varies whether rewards are dependent on vigilance-intensive responding versus making a lucky choice during a relaxed response window. We examined group by sub-task contrast differences in activation of VS and more motoric regions of striatum in response to anticipatory cues. Reward anticipation in both task conditions activated portions of striatum in both groups. In voxel-wise comparison, adults showed greater anticipatory recruitment of VS in trials involving choice during a relaxed time window, not in the more vigilance-demanding trials as hypothesized. In accord with our hypotheses, however, adults showed greater activation in dorsal striatum and putamen volumes of interest during reward anticipation under vigilance-demanding conditions. Following trial outcome notifications, adolescents showed greater activation of the VS during reward notification but lower activation during loss notification. These data extend findings of cross-sectional age-group differences in incentive-anticipatory recruitment of striatum, by demonstrating in adults relatively greater recruitment of motor effector regions of striatum by attentional and motor demands.

Immigration Detention at Sea: maritime migration governance in Australia and the sanctioning of indefinite detention for the purpose of removal

Over the past four decades, maritime geographies have become prominent sites of migration governance. While there is important scholarly work on these spaces, charting changing techniques of control and containment, what continues to demand attention is the governance that works through systematically keeping people seeking asylum mobile at sea. This article focuses on Australia, examining the coerced mobilities that follow interdictions at sea and their carceral nature. I interrogate the High Court case, CPCF v Minister for Immigration and Border Protection, which addresses the extended maritime detention of 157 people seeking asylum in June 2014. Through analysing the language used in this case, such as the conclusion by the majority that “to detain” a person at sea mandates a concomitant duty “to take” that person somewhere, I highlight how coerced mobility has become central to Australia's strategy of maritime migration governance and how this has come to legitimate detention at sea without any clear time limitation. This will reveal the extent to which carcerality informs migration governance in Australia's maritime geographies.

Artificial Intelligence in Ophthalmology – Threat or Aid?

Objective: This review seeks to identify and analyze the drawbacks and advantages associated with the integration of artificial intelligence (AI) into the field of ophthalmology. Methods: A comprehensive review of scientific literature, articles, and publications on PubMed was undertaken. Various aspects, including the effectiveness and diagnostic speed of diabetic retinopathy, as well as ethical considerations and data security, were evaluated. Results were meticulously checked, compared, and summarized. In total, 98 articles were scrutinized using keywords in both Polish and English, including “artificial intelligence,” “ethics,” “diabetic retinopathy,” and “machine learning.” Results and discussion: The application of AI in ophthalmology demonstrates significant potential in improving the diagnosis of diabetic retinopathy. AI-based systems not only contribute to facilitating and streamlining the diagnostic and therapeutic processes but also enhance therapy efficiency. However, issues related to patient data protection, physician responsibility, the cost of training adequately skilled personnel, trust in the accuracy of diagnoses, and the long-term consequences of replacing human intervention with AI necessitate careful consideration. Conclusions: AI presents substantial opportunities in ophthalmology but simultaneously poses challenges that demand diligence and attention. It is imperative to develop norms and guidelines for the responsible use of AI in ophthalmic practice, ensuring benefits for patients while minimizing potential risks and maintaining high ethical standards. This proactive approach is crucial for harnessing the full potential of AI in healthcare.

Age-related differences in resting-state, task-related, and structural brain connectivity: graph theoretical analyses and visual search performance.

Previous magnetic resonance imaging (MRI) research suggests that aging is associated with a decrease in the functional interconnections within and between groups of locally organized brain regions (modules). Further, this age-related decrease in the segregation of modules appears to be more pronounced for a task, relative to a resting state, reflecting the integration of functional modules and attentional allocation necessary to support task performance. Here, using graph-theoretical analyses, we investigated age-related differences in a whole-brain measure of module connectivity, system segregation, for 68 healthy, community-dwelling individuals 18-78years of age. We obtained resting-state, task-related (visual search), and structural (diffusion-weighted) MRI data. Using a parcellation of modules derived from the participants' resting-state functional MRI data, we demonstrated that the decrease in system segregation from rest to task (i.e., reconfiguration) increased with age, suggesting an age-related increase in the integration of modules required by the attentional demands of visual search. Structural system segregation increased with age, reflecting weaker connectivity both within and between modules. Functional and structural system segregation had qualitatively different influences on age-related decline in visual search performance. Functional system segregation (and reconfiguration) influenced age-related decline in the rate of visual evidence accumulation (drift rate), whereas structural system segregation contributed to age-related slowing of encoding and response processes (nondecision time). The age-related differences in the functional system segregation measures, however, were relatively independent of those associated with structural connectivity.

Prevalence of Back Deformities Among Primary School Students

<i>Background</i>: The high incidence of spinal abnormalities among primary school students is a pressing health issue that demands attention. Recent epidemiological studies have emphasized the importance of spinal anomalies in this specific population. The rising prevalence can be attributed to factors such as sedentary lifestyles, insufficient ergonomic practices, and a lack of awareness. Understanding the extent of these abnormalities is crucial for promptly identifying and intervening since they might affect the general welfare and educational achievement of primary school students. The aim of this study was to estimate the Prevalence of Back Deformities among Primary School Students in Khartoum, Sudan 2022-2023. <i>Materials and Methods</i>: This study is an observational, descriptive, cross-sectional community-based study conducted in four government primary schools in the Bahri locality from November 2022 to February 2023 among primary school students. Data was analyzed and interpreted using Statistical Package for the Social Sciences (SPSS) data analysis software version 26.0. <i>Results</i>: This study included a total of 383 primary school students in Bahri locality (males: 200 (52.2%) and females: 183 (47.8%). The male-to-female ratio is 1.1:1, with a mean age of 9 years and ranging from 6 to 12 years. The posture wall test and Adam forward bending test were used to diagnose coronal and sagittal deformities. The posture wall test was positive in 3 cases (0.78%). There were 3 cases of kyphosis, 2 males and 1 female. The deformity was in the thoracic region in all cases.

Auditory vigilance task performance and cerebral hemodynamics: effects of spatial uncertainty.

The vigilance decrement, a temporal decline in detection performance, has been observed across multiple sensory modalities. Spatial uncertainty about the location of task-relevant stimuli has been demonstrated to increase the demands of vigilance and increase the severity of the vigilance decrement when attending to visual displays. The current study investigated whether spatial uncertainty also increases the severity of the vigilance decrement and task demands when an auditory display is used. Individuals monitored an auditory display to detect critical signals that were shorter in duration than non-target stimuli. These auditory stimuli were presented in either a consistent, predictable pattern that alternated sound presentation from left to right (spatial certainty) or an inconsistent, unpredictable pattern that randomly presented sounds from the left or right (spatial uncertainty). Cerebral blood flow velocity (CBFV) was measured to assess the neurophysiological demands of the task. A decline in performance and CBFV was observed in both the spatially certain and spatially uncertain conditions, suggesting that spatial auditory vigilance tasks are demanding and can result in a vigilance decrement. Spatial uncertainty resulted in a more severe vigilance decrement in correct detections compared to spatial certainty. Reduced right-hemispheric CBFV was also observed during spatial uncertainty compared to spatial certainty. Together, these results suggest that auditory spatial uncertainty hindered performance and required greater attentional demands compared to spatial certainty. These results concur with previous research showing the negative impact of spatial uncertainty in visual vigilance tasks, but the current results contrast recent research showing no effect of spatial uncertainty on tactile vigilance.

Unleashing the potential: harnessing generative artificial intelligence for empowering model training

Abstract Recent strides in generative artificial intelligence, particularly large language models, have been propelled by foundation models – learning algorithms trained on extensive and diverse datasets encompassing various subjects. This technology, inspired by the complexity of the human brain, unveils a new frontier in generative Artificial Intelligence (AI), showing its potential in creativity by generating innovative content based on absorbed data and user prompts. It is forecasted that the conversational AI and virtual assistant segment is experiencing the highest growth rate within the contact center industry, projected to fuel a 24% increase in the market during 2024. In spite of all remarkable performances, the incipient stage of generative AI calls for a careful consideration, as technological and ethical challenges demand attention and awareness. This research delves into the base principle which empowers users to build personalized chatbots trained on your data. This stand-alone footprint can further exemplify the transformative potential of generative artificial intelligence, extending its reach beyond professionals to individuals and tremendously remodeling the landscape of chatbots. Text generation lies at the intersection of computational linguistics and artificial intelligence, forming a specialized area within natural language processing. It implies a thorough procedure where a model is trained to be able to recognize and interpret the context of specific input data, subsequently generating text that pertains to the input’s subject matter. We have identified gap areas that require in-depth research. For instance, a broader number of papers relies solely on architecture optimization, performance comparison or application-specific studies. Therefore, this paper gives a bird’s eye view of the effective algorithm flow of a traditional generative model, using Long Short-Term Memory networks – part of the recurrent neural networks part family. The purpose of the current study focuses to enrich the existing body of knowledge on how a response generation-based model operates, therefore paving the way for chatbots development and deployment.

Refined linkage analysis of the sulphated marine polysaccharide fucoidan of Cladosiphon okamuranus with a focus on fucose

Methylation followed by depolymerization and gas chromatography (GC) is an effective methodology for the linkage analysis of polysaccharides, including fucoidan, a sulphated algal polysaccharide. However, this sample material demands attention to experimental details to prevent aberrations in the analytical result. The use of deficient bases for methylation, the presence of water, analyte degradation during hydrolysis, and coelution of the target analytes during gas chromatography create doubts about published results. We therefore investigated critical parameters of the method and carefully optimized the steps of the protocol to ensure the integrity of the results for the fucose monomers.Fucoidan from Cladosiphon okamuranus was used as reference sample to determine the glycosidic bonds, and sulphate positions in the monomer. Fucoidan in protonated form was methylated in a strictly water-free environment using lithium dimsyl as base and methyl iodide for methylation. The methylated polymer was isolated by solid phase extraction, which was crucial to recover also the highly sulfated fraction. Hydrolysis was conducted with trifluoroacetic acid. To separate all target analytes in GC-FID/MS, a stationary phase with high cyanopropyl content (HP-88) was required, as the commonly employed phenyl siloxane phases result in co-elution, which distorts the result severely.

Assessing Antibiotic-Resistant Genes in University Dormitory Washing Machines.

University dormitories represent densely populated environments, and washing machines are potential sites for the spread of bacteria and microbes. However, the extent of antibiotic resistance gene (ARG) variation in washing machines within university dormitories and their potential health risks are largely unknown. To disclose the occurrence of ARGs and antibiotic-resistant bacteria from university dormitories, we collected samples from washing machines in 10 dormitories and used metagenomic sequencing technology to determine microbial and ARG abundance. Our results showed abundant microbial diversity, with Proteobacteria being the dominant microorganism that harbors many ARGs. The majority of the existing ARGs were associated with antibiotic target alteration and efflux, conferring multidrug resistance. We identified tnpA and IS91 as the most abundant mobile genetic elements (MGEs) in washing machines and found that Micavibrio aeruginosavorus, Aquincola tertiaricarbonis, and Mycolicibacterium iranicum had high levels of ARGs. Our study highlights the potential transmission of pathogens from washing machines to humans and the surrounding environment. Pollution in washing machines poses a severe threat to public health and demands attention. Therefore, it is crucial to explore effective methods for reducing the reproduction of multidrug resistance.

ANALYSIS OF REGULATORY AND LEGAL SUPPORT FOR THE PREVENTION OF DIABETES MELLITUS IN CHILDREN

Diabetes mellitus has become one of the most prevalent chronic diseases in childhood today. International forecasts suggest that the incidence of diabetes will continue to rise in the coming decades, leading to a lifelong burden for millions of children worldwide. Therefore, prediction, prevention, and optimal treatment of diabetes, as well as early prevention of serious long-term complications, remain essential. Providing highly qualified medical care to diabetic patients is a crucial step in preventing the development of complications. The purpose of this article is to review existing research on diabetes prevention strategies for children, considering the different levels of medical care support available. Materials and Methods. This study investigates the organization of preventive care for children with diabetes in Ukraine. Researchers employed three key methods: bibliosemantic analysis, content analysis focused on analyzing Ukraine relevant regulations and legal frameworks, and the method of systemic approach and analysis to gain a comprehensive understanding of how preventive care is currently organized for children with diabetes in Ukraine. Results. In Ukraine, preventive measures and the provision of medical care to pediatric patients with diabetes in the past years and today are regulated by a number of documents and orders of the Ministry of Health. As part of the Comprehensive Program “Diabetes Mellitus” (1999) and in accordance with the Order of the Ministry of Health of Ukraine “On Improving the Organization of Providing Endocrinological Care to the Population of Ukraine” (2006), the State Register of Patients with Diabetes Mellitus (SYNADIAB) was created. The next step was the approval of the State Target Program “Diabetes Mellitus”. Subsequently, the Project of the national program “Health 2020: Ukrainian Dimension” became an effective tool, which outlined the main principles of the program implementation in the “Endocrinology” section for 2013-2020. It defined measures at all stages of diabetes prevention, such as primary prevention, which consists of maintaining and strengthening the general state of health and preventing or delaying the development of diabetes; secondary prevention should improve early detection of diabetes mellitus; tertiary prevention, which ensures the effectiveness and safety of treatment of children with diabetes to prevent the development of long-term complications. Today, the guidelines for the management of children with diabetes mellitus have been continued in such documents as “Diabetes Mellitus in Children”, Evidence-Based Clinical Guidelines (2023) and Standards of Care (2023). Conclusion. Diabetes mellitus is a chronic disease that ranks third in prevalence after cardiovascular and cancerous diseases and second in the structure of endocrine diseases after thyroid gland pathology. Today, the prevalence of diabetes mellitus among children is constantly increasing and, therefore, solving the issues associated with this disease is one of the priority tasks for the national health care system. This is because diabetes mellitus is associated with a high risk of complications leading to loss of work capacity, disability, and mortality across various population groups. Organizing high-quality medical care and establishing an effective prevention system based on the latest medical technologies is crucial. Diabetes demands attention. Understanding the risks and prevention of the disease can significantly increase the chances of protection and a long, healthy life through timely treatment.

Systematic review and meta-analysis of the visual mismatch negativity in schizophrenia.

Mismatch negativity (MMN) is an event-related potential component automatically elicited by events that violate predictions based on prior events. To elicit this component, researchers use stimulus repetition to induce predictions, and the MMN is obtained by subtracting the brain response to rare or unpredicted stimuli from that of frequent stimuli. Under the Predictive Processing framework, one increasingly popular interpretation of the mismatch response postulates that MMN represents a prediction error. In this context, the reduced MMN amplitude to auditory stimuli has been considered a potential biomarker of Schizophrenia, representing a reduced prediction error and the inability to update the mental model of the world based on the sensory signals. It is unclear, however, whether this amplitude reduction is specific for auditory events or if the visual MMN reveals a similar pattern in schizophrenia spectrum disorder. This review and meta-analysis aimed to summarise the available literature on the vMMN in schizophrenia. A systematic literature search resulted in 10 eligible studies that resulted in a combined effect size of g = -.63, CI [-.86, -.41], reflecting lower vMMN amplitudes in patients. These results are in line with the findings in the auditory domain. This component offers certain advantages, such as less susceptibility to overlap with components generated by attentional demands. Future studies should use vMMN to explore abnormalities in the Predictive Processing framework in different stages and groups of the SSD and increase the knowledge in the search for biomarkers in schizophrenia.

"The Crusade Against the Whisker" and the Birth of the Modern Radical Beard

This paper seeks to investigate the shift in style in the last decade of the nineteenth century, when it again became customary for men to shave their beards. In order to address this topic, the historiographies of facial hair, masculinity, and radical politics in the late nineteenth and early twentieth centuries in the United States demand attention. The convergence of these three areas of study will provide the basis for this examination into this shift in style, and the social meanings that may have been placed on beards and beardlessness during this period in American history.

Bystanders to a Public Health Crisis

Per- and polyfluoroalkyl substances (PFAS) are devastating our food systems and our health. Due to widespread use, these synthetic, long-lasting chemicals, are omnipresent at dangerous levels in our envi-ronment and our homes. Recent studies link even small exposure to PFAS to a host of adverse health outcomes, including cancer, autoim-mune diseases, thyroid disease, liver damage, childhood obesity, infer-tility, and birth defects. Food consumption is a primary route of PFAS exposure. PFAS mi-grate from water, soil, fertilizers, pesticides, and compost into virtually every plant, fish, animal, and animal product, and ultimately (in the greatest concentration) into the consumer. In addition, food pro-cessing equipment, disposable dishes, and containers leach dangerous levels of these chemicals into processed food products, further infusing our every meal with PFAS. Consequently, it is no surprise everything from chocolate cake and microwave popcorn to free range eggs, wildcaught fish, organic milk, and organic kale can harbor staggering quantities of these toxic substances. Despite the widespread presence of these substances and strong sci-entific evidence of their harmful impact on humans, federal regulation of PFAS in food is currently nonexistent. At least fifteen agencies have a mandate to ensure the safety of our food. More is not always better. In the case of regulatory agencies, it can lead to fragmented demand for attention, diffusion of responsibilities, and bureaucratic bystander apathy. This story has played out time and again with other toxic con-taminants like polychlorinated biphenyls (PCBs) and pesticides and is playing out yet again with PFAS. Despite our country’s devastating experience with past contaminants and the unprecedented scientific progress of our time, the federal response to new food safety threats has only become more sluggish and inadequate. This article lays a pathway for change, taking the issue of PFAS food contamination as a case study for the broader dysfunction in the food safety regulatory system. Part II reviews the history of federal food regulation and explores the role that each federal actor in the field plays in ensuring the safety of the food supply. Part III provides back-ground on the chemical and toxicological profile of PFAS and their widespread presence in the environment in general and the food sup-ply in particular. Part IV examines possible approaches to more effec-tive regulation of environmental contaminants in food and proposes a readily available but currently overlooked mechanism for combatting the current public health crisis of PFAS in food. Lastly, Part V cata-logues the expected benefits of the solution and addresses anticipated skepticism. It concludes that the proposed approach can effectively protect consumers from PFAS in food today, while simultaneously gar-nering much needed data to usher in a more permanent solution in the future.

Differences between parents' and paediatricians' perceptions of mild respiratory infections in childhood: contrast study.

Mild respiratory infections are a common reason for consultation in paediatrics, both in the emergency department and in primary care clinics. These conditions, mostly viral and self-limiting, have a significant impact on the healthcare system, school and work absenteeism, and family routines. Despite being common and banal illnesses from a medical perspective, they involve a significant concern in families. The main objective of the contrast study was to compare the perceptions of parents and paediatricians regarding mild respiratory infections in childhood and their impact on family conciliation. Two online, cross-sectional surveys were conducted among Spanish paediatricians and parents with children aged 6 months to 12 years, involving 504 paediatricians and 1,447 families, with questions on attitudes towards visits to the paediatric consultation, care burden of minor pathologies, work, and family conciliation, and treatment and prevention of these illnesses. Results showed significant differences in paediatricians' and parents' perceptions in many aspects. According to 34.5% of paediatricians and 27% of parents, families regularly go to the paediatrician without a scheduled visit. Only 4% of parents report having self-medicated their child, while paediatricians raise this percentage significantly to 48%. Regarding the question: "it is normal for a child to have an average of 4 colds a year," only 25.5% of the surveyed families "strongly agree" unlike to 70.2% of paediatricians. 72.8% of paediatricians "strongly agree" with: "in my opinion, it is good for children to get sick to improve their immune system" reduced to 45.9% of parents. Consultations for minor pathologies represent a "high workload" for 60.9% of paediatricians, while this opinion is agreed by only 18.9% of the parents. Mild respiratory infections in childhood are perceived differently by paediatricians and parents. While paediatricians perceive them as a common and manageable phenomenon, parents tend to show higher concern and demand for medical attention. This study underlines the need to improve communication between paediatricians and parents to align perceptions, optimise the use of the health system resources, and improve the efficiency in the management of these common paediatric illnesses.

Auditory change detection and visual selective attention: association between MMN and N2pc.

While the auditory and visual systems each provide distinct information to our brain, they also work together to process and prioritize input to address ever-changing conditions. Previous studies highlighted the trade-off between auditory change detection and visual selective attention; however, the relationship between them is still unclear. Here, we recorded electroencephalography signals from 106 healthy adults in three experiments. Our findings revealed a positive correlation at the population level between the amplitudes of event-related potential indices associated with auditory change detection (mismatch negativity) and visual selective attention (posterior contralateral N2) when elicited in separate tasks. This correlation persisted even when participants performed a visual task while disregarding simultaneous auditory stimuli. Interestingly, as visual attention demand increased, participants whose posterior contralateral N2 amplitude increased the most exhibited the largest reduction in mismatch negativity, suggesting a within-subject trade-off between the two processes. Taken together, our results suggest an intimate relationship and potential shared mechanism between auditory change detection and visual selective attention. We liken this to a total capacity limit that varies between individuals, which could drive correlated individual differences in auditory change detection and visual selective attention, and also within-subject competition between the two, with task-based modulation of visual attention causing within-participant decrease in auditory change detection sensitivity.

Academic Medicine and Rural Health System Partnerships: Enhancing Education While Advancing Physician Workforce Priorities.

A worsening shortage of rural physicians paralleling increasing health disparities demands attention. Past and ongoing efforts to address this shortage have had positive effects and can inform new strategies to achieve even greater impact. Interventions have included the development of regional medical school campuses and rural-focused tracks to recruit medical students from rural areas, expansion of rural-based graduate medical education (GME) programs and tracks, and use of institutional and individual financial incentives for rural-based training and/or practice. National policy has also taken aim at this challenge with provisions aimed at expanding rural GME in the Medicare, Medicaid, and State Children's Health Insurance Program Balanced Budget Refinement Act of 1999 and the Consolidated Appropriations Act of 2021. Additionally, several states have funded growth in GME, and supportive pathways for Medicare reimbursement and for Veterans Administration funding have been implemented. The authors recommend a new strategy for bolstering the rural physician workforce, focused on using academic-rural partnerships to incorporate rural rotations as a routine part of GME. They explain how the current health care landscape supports this approach and outline additional steps toward implementation. Centralized data collection and analysis are noted as essential to guide future efforts.
