The field of sociology of quantification has, to a noticeably lesser degree, explored mathematical modeling in contrast to its significant investigation of statistical, metric, and algorithmic forms of quantification. This study explores whether concepts and approaches from mathematical modeling offer nuanced tools for the sociology of quantification, ensuring methodological soundness, normative appropriateness, and fairness in numerical data. Sensitivity analysis techniques are suggested as a means to uphold methodological adequacy; the various dimensions of sensitivity auditing are dedicated to addressing normative adequacy and fairness. Our inquiry also encompasses the ways in which modeling can influence other cases of quantification, ultimately promoting political agency.
Sentiment and emotion's influence on market perceptions and reactions is indispensable to financial journalism. Nonetheless, the COVID-19 pandemic's effect on the linguistic choices in financial publications has yet to be thoroughly investigated. To bridge this gap, this study compares financial news from specialized English and Spanish newspapers, focusing on the years preceding the COVID-19 outbreak (2018-2019) and the years of the pandemic (2020-2021). We intend to investigate the economic volatility of the latter period as reflected in these publications, and to explore the alterations in expressed feelings and sentiments in their language in relation to the previous timeframe. For the purpose of this analysis, we constructed similar news corpora from the well-regarded publications The Economist and Expansion, spanning both the pre-COVID and pandemic periods. Employing a corpus-based, contrastive approach to EN-ES, we examine lexically polarized words and emotions to understand the publications' positioning in the two distinct periods. To further refine the lexical items, we utilize the CNN Business Fear and Greed Index, acknowledging that fear and greed are frequently linked to the volatile and unpredictable fluctuations in financial markets. Expected to emerge from this novel analysis is a holistic portrayal of the emotional language used in English and Spanish specialist periodicals to describe the economic disruption of the COVID-19 period, in relation to their prior linguistic characteristics. This research contributes significantly to our knowledge of sentiment and emotion in financial journalism, focusing on how crises influence and reshape the linguistic expressions used in the field.
Diabetes Mellitus (DM), a prevalent global health concern, significantly contributes to numerous health crises worldwide, and sustainable health monitoring is a key development priority. Reliable monitoring and prediction of Diabetes Mellitus are currently achieved through the integrated application of Internet of Things (IoT) and Machine Learning (ML) technologies. Emergency medical service The performance of a model for real-time patient data collection, integrated with the Hybrid Enhanced Adaptive Data Rate (HEADR) algorithm of the Long-Range (LoRa) IoT protocol, is presented in this paper. Dissemination and dynamic range allocation of data transmission are used to assess the performance of the LoRa protocol within the Contiki Cooja simulator environment. Machine learning prediction is facilitated by applying classification methods to identify diabetes severity levels in data gathered using the LoRa (HEADR) protocol. Machine learning classifiers of diverse types are employed for forecasting; their results are then evaluated against established models. Python's Random Forest and Decision Tree classifiers excel in precision, recall, F-measure, and ROC (receiver operating characteristic) metrics compared to other algorithms. Using k-fold cross-validation, we ascertained that applying it to k-nearest neighbors, logistic regression, and Gaussian Naive Bayes resulted in improved accuracy levels.
Image analysis using neural networks is significantly enhancing the precision and complexity of medical diagnostics, product categorization, inappropriate behavior surveillance, and detection. In this research, considering the current state, we scrutinize contemporary convolutional neural network architectures developed in recent years to categorize driving habits and driver distractions. Our principal pursuit is to assess the performance of such architectures, leveraging only free resources (namely, free graphic processing units and open-source platforms), and to ascertain the extent of this technological evolution's accessibility for everyday users.
In Japan, the current understanding of menstrual cycle length differs from the WHO's, and the original data is no longer relevant. The aim of this study was to evaluate the distribution patterns of follicular and luteal phase lengths in modern Japanese women with diverse menstrual cycle characteristics.
The analysis of basal body temperature data, from a smartphone application, collected between 2015 and 2019 from Japanese women, employed the Sensiplan method to calculate the length of the follicular and luteal phases in this study. Over nine million temperature readings, originating from more than eighty thousand participants, were the subject of detailed analysis.
The low-temperature (follicular) phase, lasting an average of 171 days, demonstrated a shorter duration among participants aged 40-49 years. The high-temperature (luteal) phase, on average, lasted 118 days. The extent of fluctuation (variance) and the gap (maximum-minimum difference) in the duration of low-temperature periods was markedly greater in women under 35 than in women over 35 years old.
A contraction of the follicular phase in women between 40 and 49 years of age suggests an association with the rapid depletion of ovarian reserve, with the age of 35 being a pivotal point in the progression of ovulatory function.
The observed shortening of the follicular phase in women aged 40 to 49 years suggested a correlation with the accelerated decline of their ovarian reserve, while the age of 35 represented a critical inflection point in the function of ovulation.
A definitive explanation for the relationship between dietary lead and the intestinal microbiome is still absent. To examine the correlation between microflora changes, anticipated functional genes, and lead exposure, mice were fed diets amended with progressively higher concentrations of a single lead compound (lead acetate) or a well-defined complex reference soil containing lead, such as 625-25 mg/kg lead acetate (PbOAc) or 75-30 mg/kg lead in reference soil SRM 2710a, containing 0.552% lead, alongside other heavy metals like cadmium. Microbiome analysis, using 16S rRNA gene sequencing, was conducted on fecal and cecal samples gathered after nine days of treatment. The mice's ceca and feces showed evidence of treatment influence on the microbiome. Pb exposure in mice, either through Pb acetate or as part of SRM 2710a, led to statistically different cecal microbiomes, excepting a limited number of examples, regardless of dietary form. An increase in the average abundance of functional genes related to metal resistance, including those for siderophore production and arsenic/mercury detoxification, was observed in conjunction with this. CN128 concentration In controlled microbiomes, Akkermansia, a prevalent gut bacterium, held the top position, while Lactobacillus achieved the same distinction in treated mice. The Firmicutes/Bacteroidetes ratio in the ceca of mice receiving SRM 2710a treatment exhibited a more substantial increase in comparison to those receiving PbOAc, implying a shift in gut microbiome activities associated with the propensity towards obesity. Mice receiving SRM 2710a treatment demonstrated a statistically higher average abundance of functional genes involved in the metabolic pathways of carbohydrate, lipid, and fatty acid biosynthesis and degradation within their cecal microbiomes. An elevation of bacilli/clostridia in the ceca of mice treated with PbOAc was noted, and could be an indicator of an increased probability of the host developing sepsis. Possible modulation of the Family Deferribacteraceae by PbOAc or SRM 2710a may affect the inflammatory response. The interplay between microbiome makeup, predicted functional capabilities, and lead (Pb) levels, particularly in soil, might unveil new strategies for remediation that limit dysbiosis and mitigate potential health consequences, ultimately assisting in choosing the most suitable treatment for contaminated areas.
The paper focuses on enhancing the applicability of hypergraph neural networks in the low-label regime by integrating contrastive learning inspired by image and graph analysis techniques; we call this novel approach HyperGCL. The construction of contrasting viewpoints within hypergraphs is addressed through the lens of augmentations. Our solutions are detailed across two separate facets. With domain knowledge as our foundation, we devise two strategies for augmenting hyperedges with embedded higher-order relations, and apply three vertex enhancement methods from graph-structured datasets. Epimedii Herba Secondly, seeking more effective data-driven perspectives, we introduce, for the first time, a hypergraph generative model designed to create augmented viewpoints, followed by an end-to-end differentiable pipeline for concurrently learning hypergraph augmentations and model parameters. Hypergraph augmentations, both fabricated and generative, are a reflection of our technical innovations. The experimental findings from the HyperGCL study reveal (i) the most substantial numerical gains arise from augmenting hyperedges within the fabricated augmentations, implying that higher-order structural information within the data structure is generally more crucial for subsequent tasks; (ii) that generative augmentation methods excel in preserving higher-order information, thus further improving generalizability; (iii) that HyperGCL consistently boosts robustness and fairness in learning hypergraph representations. The HyperGCL codebase is hosted on GitHub, specifically at https//github.com/weitianxin/HyperGCL.
