Published: November 2024

MVImgNet is a large-scale dataset that contains multi-view images of ~220k real-world objects in 238 classes. As a counterpart of ImageNet, it introduces 3D visual signals via multi-view shooting, making a soft bridge between 2D and 3D vision. This paper constructs the MVImgNet2.0 dataset that expands MVImgNet into a total of ~520k objects and 515 categories, which derives a 3D dataset with a larger scale that is more comparable to ones in the 2D domain. In addition to the expanded dataset scale and category range, MVImgNet2.0 is of a higher quality than MVImgNet owing to four new features: (i) most shoots capture 360° views of the objects, which can support the learning of object reconstruction with completeness; (ii) the segmentation manner is advanced to produce foreground object masks of higher accuracy; (iii) a more powerful structure-from-motion method is adopted to derive the camera pose for each frame of a lower estimation error; (iv) higher-quality dense point clouds are reconstructed via advanced methods for objects captured in 360
°
views, which can serve for downstream applications. Extensive experiments confirm the value of the proposed MVImgNet2.0 in boosting the performance of large 3D reconstruction models. MVImgNet2.0 will be public at
luyues.github.io/mvimgnet2
, including multi-view images of all 520k objects, the reconstructed high-quality point clouds, and data annotation codes, hoping to inspire the broader vision community.

Published: November 2024

With the rapid development of industry in China, the scale of coal mining continues to expand, leading to an increase in safety hazards and frequent accidents. Among these, gas overrun accidents account for a significant proportion, and changes in atmospheric pressure are a major factor affecting the outburst of coal mine gas. This paper takes a mine in Hebei Province, China, as the research object, combining on‐site data detection with numerical simulation methods to explore the influence of atmospheric pressure changes on underground air pressure and gas emission. The results show that changes in atmospheric pressure are synchronized with changes in underground air pressure, and the rate of change affects the amount of gas emitted. When the rate of pressure decrease is below 0.04 KPa/h, the impact is slower, and the peak time of gas emission is later than the time of minimum pressure. Simulation results indicate that the pressure difference caused by changes in atmospheric pressure is transferred to the underground air pressure, affecting the distribution of methane at the working face and the range of air leakage in the goaf. The greater the pressure difference, the higher the concentration of methane at the working face, the greater the air leakage in the goaf, and the more gas brought from the deep part of the goaf to the working face. These findings are of great significance for understanding the mechanism of gas emission and preventing gas accidents.

Smart contracts have the ability to address a variety of important obstacles in the construction business, such as contract conflicts and payment issues. Likewise, it may facilitate the adoption of building information modeling (BIM) in the industry. Poor adoption of distributed ledger technology in the Arabian construction sector stems from a variety of impediments. The usage of smart technology is growing in popularity across the globe in the recent few years. Nonetheless, in the Arab world, there are not enough experts who are aware of how smart contract technology can make the construction sector more efficient, collaborative, and transparent in the digital era. With that in mind, the purpose of this study is to evaluate the benefits and drawbacks of using smart contracts in the construction industry. To accomplish its goals, this study mostly uses descriptive statistics to analyze the collected data from questionnaire surveys. This research utilizes an illustrative diagram to map the potentials and obstacles to the adoption of smart contracts from the respondents’ perspective. According to the conducted analysis, there are five main potentials and barriers to smart contract implementation, namely, the Internet of Things, data reliability, stakeholders, security for distributed systems, and finance and economics. Additionally, the questionnaire survey yielded 21 potentials such as better risk allocation, decreased transaction time and cost, and ease of understanding by multiple stakeholders. Moreover, the conducted survey obtained 19 barriers such as slow learning curve, high training and education costs, and cybersecurity concerns. It can be argued that the present research study can assist in endorsing the adoption of smart contracts in the Arabian construction market.

Insufficient evidence exists to assess the effect of titin antibodies on nonthymoma myasthenia gravis (MG) treatment and prognosis. We analyzed whether titin antibody‐positive patients with nonthymoma MG (non‐TMG) have a higher frequency of hospitalization than those who are titin antibody‐negative. We retrospectively analyzed patient data from January 2017 to July 2022 obtained from an institutional databank. We compared the clinical characteristics, treatment regimens, and MG‐related annual hospitalization rate between titin antibody‐positive (Titin+ group) and titin antibody‐negative (Titin− group) patients with non‐TMG. Multivariate logistic regression was employed to examine the factors associated with multiple hospital admissions (≥ 2). Finally, 170 patients with non‐TMG were included, of whom 67 (39.4%) were Titin+ and 103 (60.6%) were Titin−. Compared with the Titin− group, the Titin+ group exhibited a notably higher annual hospitalization rate (p = 0.011). Multivariate logistic regression analysis revealed that titin antibody positivity was significantly associated with multiple hospitalizations. The optimal cutoff value for titin antibody levels related to multiple hospitalizations was 3.085. In patients with non‐TMG, titin antibodies were associated with more frequent hospitalizations. For these patients, especially those with titers ≥ 3.085, close monitoring of clinical symptom changes may reduce relapse.
Regenerative Braking in PV‐Mounted Electric Vehicle With Reduced Switch VSI‐Driven BLDC Motor and HAP‐FUP Controller
Authors: Carter S. B. Ron , S. Thangavel
Published: November 2024

The electric vehicle’s overall efficiency can be augmented through the implementation of the regenerative braking system (RBS), which serves to extend the drive range. This paper explores a method for further increasing said range by implementing a roof‐mounted photovoltaic (PV) system in conjunction with RBS, resulting in an impressive 25.14% increase to the vehicle’s driving distance. The roof‐mounted PV and regenerative braking work together to charge the dual battery pack present within the vehicle, following a specific sequence as dictated by its controller. Maximum energy is extracted from the PV module via employment of a particle swarm optimization (PSO)‐based maximum power point tracking (MPPT) algorithm, while propulsion is provided through utilization of a brushless direct current (BLDC) motor driven by reduced switch voltage source inverter (VSI). The BLDC motor itself is controlled utilizing field‐oriented control (FoC), with hybrid ANN‐PID and Fuzzy‐PID (HAP‐FUP) controllers employed at the outer loop; furthermore, HAP‐FUP controller performance was compared favorably against other top controllers such as model predictive controller (MPC), sliding mode controller (SMC), and conventional PID controller, ultimately demonstrating superior performance when it comes to reducing rise time and settling time of vehicle speed.

Authors: Yang Hongbo , Chen Meiping , Liu Shanshan , Zhang Yuelun , Wang Linjie , Duan Lian , Gong Fengying , Zhu Huijuan , Pan Hui
Published: November 2024

Objective: Adult growth hormone deficiency (AGHD) is characterized by central adiposity and metabolic disorders. Asprosin, a newly discovered adipokine, plays a crucial role in connecting adipose tissue function with the development of metabolic syndrome. This study aims to evaluate the circulating levels of asprosin in AGHD patients and explore the potential correlation between asprosin levels and various metabolic parameters.

Subjects and Methods: Forty male patients with AGHD (mean age: 33.5 ± 9.5 yrs and mean BMI: 25.0 ± 4.5 kg/m2) and forty age‐, gender‐, and BMI‐matched non‐AGHD controls were enrolled. Medical history, anthropometric parameters (weight, height, waist circumference), and biochemical and hormonal investigations were collected from the electronic medical record system. Fat mass, fat percentage, and fat‐free mass (FFM) were evaluated by bioelectrical impedance. Serum levels of asprosin were measured by ELISA.

Results: Patients with AGHD demonstrated notably increased waist‐to‐hip ratios, triglyceride levels, and decreased HDL‐cholesterol levels compared with the control group. In additionally, AGHD patients exhibited significantly higher serum levels of asprosin compared with controls (p = 0.039). A notable association was observed between serum asprosin levels and FFM, triglycerides, and HDL‐cholesterol levels in the whole population.

Conclusions: Our study highlights distinct metabolic alterations in AGHD patients when matched for BMI with controls and investigates variations in serum asprosin levels for the first time. These findings have significant implications for identifying potential biomarkers for metabolic syndrome risk in AGHD patients and informing future treatment approaches.

Published: November 2024

Biochar is a promising solution in the competent removal of such toxicants due to its cost‐effectiveness, natural properties, biologically rich composition, and environment‐friendly characteristics. All the possible heavy metals found in industrial effluents and how to treat them with biochar‐based adsorption strategies to lead to a cleaner hydrosphere system were analyzed. Biochar interactions in heavy metal adsorption are studied and profiled to a small extent to allow regional knowledge of how these interactions occur and how biochar studies are taking place. Industrial effluents possess various toxic pollutants that extend their exposure to all kinds of living organisms, contaminating and degrading the biosphere. Adsorption helps mitigate difficulties such as wastewater treatment, remediation studies, and hazardous waste management, providing a sustainable and quality life. The characteristics of biochar produced through pyrolysis using different biomasses analyzed are carbon 35–90 wt%, surface area 5–2100 m2/g, and total pore volume 0.001–50 cm3/g at the temperature range of 400°C–750ºC. The optimum conditions required for maximum adsorption efficiency (96%–99%) of heavy metals majorly lie under the range of temperature 30°C–60°C, pH 5–8, and time 30 min to 1 h. The outcome of this review has significant results on remediation techniques, highlighting biochar’s potential as a flexible tool and as an adsorbent in addressing the challenges related to the possible threats implied by heavy metal contamination in industrial effluents.

Characterising the Time Course of the Dilatory Response of Healthy Retinal Arteries during Flicker-Light Provocation
Authors: Summers Robert J. , Heitmar Rebekka
Published: November 2024

Introduction: The dilatory response of healthy retinal arterioles to flicker-light (FL) provocation appears to be biphasic. The vessel diameter rapidly increases (acute phase) over 5–10 s, then barely increases thereafter (maintenance phase) until FL cessation. This reaction is usually characterised at a single point by two parameters: maximum dilation (MD) relative to baseline diameter (MD, %) and time to MD (RT, s). This paper describes the biphasic reaction of retinal arteries during FL provocation using a bi-linear function. Methods: Retinal arterioles from 45 adults were examined during flicker provocation. Each individual time course of arterial diameter change during FL provocation was characterised by a bi-linear equation and compared with MD and RT. Results: Slopes of the acute phase were 0.506%/s, and the maintenance phase was nearly flat (0.012%/s). The mean time at which the reaction changed from acute to maintenance phase was 7.4 s which is significantly different from RT (16.0 s). Mean dilation at this point (2.987%) was significantly different from MD (3.734%), but it was still 80% of MD in less than half of RT. Conclusion: Bi-linear fitting parameters better characterises the arterial dilatory response than MD and RT. Further stratification of clinical groups using bi-linear fitting may provide insight of the underlying physiology of vessel dilation for different pathologies.
Sex-Based Differences in Long-Term Outcomes Following Transcatheter Closure of Patent Foramen Ovale for Cryptogenic Stroke
Authors: Flores-Umanzor Eduardo , Abrahamyan Lusine , Asghar Areeba , Schrutka Lore , Everett Karl , Lee Douglas S. , Osten Mark , Benson Lee , Horlick Eric
Published: November 2024

BACKGROUND:

Evidence from trials suggests that patent foramen ovale closure is superior to medical therapy alone in reducing stroke recurrence in men but not in women. Evidence from real-world data on the impact of sex on outcomes after patent foramen ovale closure, however, remains scarce. Therefore, the present study aimed to assess sex-based differences in long-term outcomes after transcatheter closure of patent foramen ovale.

METHODS:

This was a single-center, retrospective cohort study enrolling patients who underwent transcatheter patent foramen ovale closure to prevent recurrent cerebrovascular events. Detailed information from medical charts was entered into a clinical registry, which has been linked to population-based administrative health databases in Ontario. Procedural, short, and long-term outcomes have been compared by sex.

RESULTS:

Of the 783 patients included in the sample, 349 (44.5%) were women and 434 (55.5%) were men. Women were younger and had a higher rate of migraine, while men had a higher prevalence of cardiovascular risk factors. No differences were observed in procedural and 30-day outcomes by sex. At a median follow-up of 14 years, the event rates of recurrent cerebrovascular events, survival, and new-onset atrial fibrillation were not different by sex. In adjusted analysis, men experienced higher rates of pacemaker implantation (hazard ratio, 5.62 [95% CI, 1.57–20.1]).

CONCLUSIONS:

No sex-based differences in recurrent cerebrovascular events, survival, or new-onset atrial fibrillation were observed in this study, suggesting equal benefits for both sexes. Future studies should report outcomes by sex to enhance the reproducibility of our findings and help support guideline development.

Published: November 2024

BACKGROUND:

A limited transthoracic echocardiogram (TTE) can be an appropriate, lower-cost substitute for a full TTE. We assessed the impact of an electronic health record alternative alert promoting the adoption of limited TTEs on the ordering practices of cardiology clinicians and primary care providers and captured their perspectives on the initiative.

METHODS:

The alert was deployed in a cardiology clinic and 4 primary care clinics at an academic medical center. The alert provided clinical guidance on the appropriate use of limited TTEs when a clinician selected a full TTE order. We used logistic regression to estimate the change in the proportion of limited versus full TTEs ordered between the baseline and intervention periods in clinics with and without the alert. We also conducted interviews with 24 clinicians (5 cardiologists and 19 primary care providers) to identify implementation barriers and facilitators.

RESULTS:

Cardiology clinicians ordered 10 654 and 3761 TTEs during the baseline and intervention periods, respectively, for 9100 patients. Primary care providers ordered 723 and 617 TTEs during the baseline and intervention periods for 1273 patients. The model estimated that the percentage of limited TTEs ordered increased by 16.1±2.3 percentage points (
P
<0.0001) in the cardiology clinic with the alert and by 13.2±1.5 percentage points (
P
<0.0001) in the primary care clinics with the alert from baseline to post-intervention. Ordering practices did not change in the cardiology (0.7±0.6 percentage points;
P
=0.24) or primary care (0.7±1.0 percentage points;
P
=0.52) clinics without the alert. Clinicians viewed the alert as acceptable. Cardiologists appreciated that the alert was concise, whereas primary care providers wanted more information from the alert.

CONCLUSIONS:

An alternative alert providing clinical guidance on the use of limited TTEs at the point of care increased the selection of this lower-cost test in cardiology and primary care clinics. Perspectives on the alert differed between specialists and nonspecialists, highlighting the importance of tailoring intervention design to clinical expertise.
Stem, prefix or prefixoid?
Authors: Marinis Michail I.
Published: November 2024

In this study, I parameterize the five tests proposed by Stevens (2005) for characterizing an element as an affixoid and formulate ten criteria for prefixation. Using these criteria, I analyze the morphological status of the initial components of Modern Greek words beginning with pale- and paʎo-. Contrary to Giannoulopoulou’s (1999) analysis of paleo- as a “confix” and paʎo- as a “stem”, I argue that pale- is a stem that has two allomorphic realizations: pale~paʎ. pale- is marked as [+learnèd] and paʎ- as [-learnèd]. While paʎo- historically derives from pale-, it has acquired a distinct morphological status and should now be considered a prefixoid. The ten criteria I present could serve as a model for determining the morphological status of initial elements in other Greek morphological structures and potentially in other languages where this status is ambiguous. Finally, I propose that prefixation in Greek differs from that in word-based languages. In Greek, prefixation is not a case of morphologization; rather, prefixes originate in and remain confined to the morphological domain.
Computational valency lexica and Homeric formularity
Authors: McGillivray Barbara , Rodda Martina Astrid
Published: November 2024

The wider availability of large-scale datasets and reproducible algorithms has boosted the application of NLP to living languages. On the other hand, dead languages benefit from the availability of curated resources both to offset the sparseness of available data and to make data accessible to researchers. We present here AGVaLex, a computational valency lexicon automatically extracted from the Ancient Greek Dependency Treebank. It contains quantitative corpus-driven morphological, syntactic and lexical information about verbs and their direct and indirect arguments and has a wide range of applications for the study of Ancient Greek. To illustrate these applications, we offer a case study that compares the semantic flexibility of transitive verb formulae in archaic Greek epic to a non-formulaic corpus, with the goal of detecting unique patterns of variation. We also illustrate the possibilities afforded by AGVaLex to scholars with a less extensive background in computational corpus-based research.
The impact of insubordination on the history of Greek
Authors: la Roi Ezra
Published: November 2024

In this paper, I trace the impact of insubordination and semi-insubordination on the history of Greek, focusing on its impact on the modal system used to express speech acts. Starting from the cross-linguistic connections of insubordinate and semi-insubordinate ἵνα and να constructions with those found in other languages, I show that ἵνα only had subordinate usages in Classical Greek (including in dyadic syntactic contexts), but developed insubordinate usages for directive and wish speech acts in Post-Classical Greek. In Medieval Greek, insubordinate να spreads pragmatically to other speech acts, e.g. to exclamatives, interrogatives and various assertives (e.g. counterfactual apodoses or double negative declaratives). In Modern Greek, insubordinate να has obtained novel usages in interrogative speech acts too and gained paradigmatic strength as it competes with the imperative and the future. Semi-insubordinate patterns are first developed in Medieval Greek (with ἴσως νὰ + main verb) but spread formally and functionally to other parts of the modal system, expressing epistemic possibility, probability, counterfactuality and avertives.
Extending Tactile Space With Handheld Tools: A Re-Analysis and Review
Authors: Miller Luke E. , Farnè Alessandro
Published: November 2024

Tools can extend the sense of touch beyond the body, allowing the user to extract sensory information about distal objects in their environment. Though research on this topic has trickled in over the last few decades, little is known about the neurocomputational mechanisms of extended touch. In 2016, along with our late collaborator Vincent Hayward, we began a series of studies that attempted to fill this gap. We specifically focused on the ability to localize touch on the surface of a rod, as if it were part of the body. We have conducted eight behavioral experiments over the last several years, all of which have found that humans are incredibly accurate at tool-extended tactile localization. In the present article, we perform a model-driven re-analysis of these findings with an eye toward estimating the underlying parameters that map sensory input into spatial perception. This re-analysis revealed that users can almost perfectly localize touch on handheld tools. This raises the question of how humans can be so good at localizing touch on an inert noncorporeal object. The remainder of the paper focuses on three aspects of this process that occupied much of our collaboration with Vincent: the mechanical information used by participants for localization; the speed by which the nervous system can transform this information into a spatial percept; and whether body-based computations are repurposed for tool-extended touch. In all, these studies underscore the special relationship between bodies and tools.
Gains from Contractualization: Evidence from Labor Regulations on Chinese Workers
Authors: Gao Qin , Riviere Candice Yandam
Published: November 2024

The 2008 Labor Contract Law of China stipulates that all employment relationships must be covered by a written labor contract. This regulation considerably strengthened employment protection for workers. Using a unique longitudinal dataset, the China Labor-force Dynamics Survey (2012, 2014, and 2016 waves), this article estimates the impact of the formal contractualization of labor relations on workers’ labor market outcomes, social insurance participation, and job satisfaction. We find that obtaining a labor contract was strongly associated with an increase in salary, a decrease in working overtime hours, and greater participation in unemployment and pension insurances. In terms of job satisfaction, workers who obtained a labor contract reported being less satisfied with their workplace environment and income than they had anticipated. This is not to suggest that workers are not benefiting from the law. Instead, it suggests that workers had higher expectations from benefits gained through contractualization than what they derived.
Platystele shanti, a petite novel jewel from Costa Rica
Authors: KARREMANS ADAM P.
Published: November 2024

A new species of Platystele is described from the Juan Castro Blanco National Park area, around Ciudad Quesada in Costa Rica. The petite novelty is morphologically similar to P. propinqua (Ames) Garay, but with the leaves spathulate, the inflorescence pendent becoming two to three times longer than the leaf, and bearing up to 25 flowers per coflorescence. The yellow flowers suffused with reddish-purple are smaller, with the segments recurved, the sepals and petals are glandular papillose on the adaxial surface, and sepals have short, blunt tails. The new species grows as an epiphyte in primary and secondary forest at elevations ca. 1800–1900 m, and seems to be endemic to the windy slopes of the Platanar Volcano, where it is locally abundant.

Domestic Accounts of China’s Belt and Road Initiative as an Internally Oriented Soft Power Exercise
Authors: Zhu Runping , Ma Zhipeng , Krever Richard
Published: November 2024

China’s Belt and Road Initiative is one of the world’s largest and most significant externally oriented soft power initiatives. Originally envisaged as a series of development projects in countries on historic land and sea trade routes between China and Europe, the initiatives quickly expanded to encompass projects around the globe. The projects, funded using Chinese finances and carried out for the most part by Chinese contractors, provide tangible benefits for recipient countries, such as ports, bridges, train systems, telecommunication systems, medical assistance, and much more. The project outputs provide invaluable soft power benefits for China. Separately, the Chinese government is able to use descriptions of the projects as internally oriented soft power tools that can enhance domestic support for the government and the Communist Party by describing the benefits for China that flow from the Belt and Road projects. This article reviews messaging about the Belt and Road initiative projects posted online for Chinese readers to see how the Chinese government has created internally oriented soft power messages based on its projects abroad.
Policy Framing, Social Networks, and Teacher Perspectives in a Technology Rollout
Authors: Hashim Ayesha K. , Kearney Caitlin E.
Published: November 2024

Drawing on theories of framing and social networks, we examine how educators define policy goals in a technology rollout, and how this framing process shapes teacher attitudes for technology. We analyzed social network data and 37 interviews with district leaders, digital learning coaches, and school staff from six elementary schools in a mid-sized district in California. These data suggest that school leaders and teachers re-framed district reform messages in different ways depending on the density of dialogue in their networks and who had social influence. These framings supported teacher motivation for using technology in ways that aligned to or built upon the district's instructional goals, or prompted teachers to resist change and/or make compliance-oriented and superficial shifts in their practice. We argue that district leaders should attend to school context when implementing technology rollouts and proactively engage school actors to define the goals of technology. We caution that technology rollouts demand sudden and intensive shifts in teacher work roles and can foster resistance to change without adequate time and support.

Purpose: We examine how educators define policy goals in a technology rollout and how framing shapes teacher attitudes for using technology. Research methods: We situate our study in a California district that distributed tablets and laptops to support online-enabled instruction and assessment under the Common Core State Standards. Drawing on framing and social network theories, we analyzed social network data and 37 interviews with district leaders, digital learning coaches, and school staff from six elementary schools in the 2014–15 school year to describe how school actors framed the purpose of technology and expectations for instructional change across school networks. Findings: School leaders and teachers re-framed reform messages from the district central office in distinct ways depending on their social networks. We observed framings that motivated teacher engagement with the technology rollout in schools with denser social networks and where influence was shared with district actors such as digital learning coaches. Teachers in these networks had better access to information and instructional support. We found compliance, superficial, and rival framings of technology in schools with less dense social networks and where teachers solely exercised influence. Teachers in these networks had limited access to information and instructional support. Implications: Our findings suggest that district leaders should attend to school context when implementing technology rollouts. Technology rollouts require sudden and intensive shifts in teacher work roles and can foster resistance without adequate support. School leaders and teachers may need time to build the knowledge, skills, and experience needed to engage in productive framing about technology and instruction.
Developing a stochastic linear elastic material model and composite laminate theory including failures, using the fiber bundle–based approach—Part I: Stochastic Linear Elastic Material Model
Authors: Vas László Mihály , Tamás Péter
Published: November 2024

This paper presents a novel theoretical statistical material model, which is a kind of extension of the usual 3D Hooke’s law and can take into account the damage process up to the final failure as well. This material model can provide the stress response also together with the damages to multiaxial short time alternating strain loads. It was developed by utilizing our earlier validated results of applying E-bundles for modelling stress-strain curve of different types of fibrous materials and fibre-reinforced composite sheets subjected to simple (uniaxial) mechanical loads. Based on the fiber bundle cells (FBC) theory, we introduced the so-called memory reliability functions to take into account the different changing strain loads including both the monotone, the pulsating and the alternating modes. We proved that the duplex compressive–tensile memory reliability function is the product of the compressive and the tensile memory reliability functions. Utilizing the generalized Hooke’s law and the memory reliability functions, we developed a stochastic linear elastic material law that also represents the damage and failure processes with normal and shear strain loads. This made it possible to calculate the expected value as the variance of the stress response process and determine its confidence interval at any strain load.
A portrait of the life, work and legacy of Roberto Corral / Una mirada a la vida, obra y legado de Roberto Corral
Authors: Rodríguez-Mena Mario , Rodríguez-Arocho Wanda C.
Published: November 2024

This work has the purpose of examining the life and academic production of the Cuban psychologist and educator Roberto Corral Ruso (1947–2024). Categories of analysis proposed by Vygotsky and Dafermos that focus on the production of knowledge from a historical and sociocultural perspective are used as a conceptual framework for the examination. From these categories we address the biography and training of Corral, the sociocultural context in which he developed his ideas and his work in psychology, the trends in philosophy and science that marked that development, what he defined as his objects of study and the productions that resulted from his work, and the network of interpersonal relationships and collaborations that it established. We end with a general conclusion about his legacy to Cuban and Ibero-American psychology.

Published: November 2024

Perfluorooctane sulfonate (PFOS) is a synthetic persistent organic compound that is widely used in industrial products. Studies have shown that PFOS can accumulate in environment and pose a threat to human health. As the kidney is the main excretory organ for PFOS, it is important to study PFOS damage to the kidney to investigate its toxicity. Human proximal tubular epithelial cells (HK-2) were treated with 200 μM PFOS or 1 μM Fer-1. Cell viability, the levels of MDA, GSH, intracellular iron ion, and GPX-4 were determined. The expression of KIM-1 and endoplasmic reticulum stress (ERS) related proteins were determined. The expression levels of KIM-1, a marker of renal tubular injury, and ERS-related proteins, GRP78, ATF6, IRE1, and PERK, were significantly increased in HK-2 cells exposed to PFOS. The levels of MDA and intracellular total iron ion also were significantly increased in HK-2 cells exposed to PFOS and the levels of GSH and GPX-4 were significantly decreased. PFOS can damage HK-2 cells through ferroptosis and endoplasmic reticulum stress, which provides a theoretical foundation for exploring the toxicity of PFOS to the kidney.
Mandibular Periostitis Ossificans in a 17-Week-Old Male Great Dane
Authors: Hoane Maureen
Published: November 2024

This case report describes the clinical, radiographic, and histopathological features of a self-limiting mandibular swelling in a juvenile, large breed dog with a diagnosis of mandibular periostitis ossificans (MPO). This is a pathologic syndrome of immature large breed dogs that presents with a unilateral, nonpainful, caudal mandibular swelling centering on the erupting first molar tooth. This condition affects dogs with a median age of approximately 4 months. The diagnosis of MPO, in this case, resulted from the assimilation of clinical and radiographic findings, along with woven bone proliferation on histopathology. A distinct “double cortex” seen on radiographs of the caudal mandible is a defining characteristic of MPO that is most likely due to an additional cortical bone layer being produced on the mandible. MPO spontaneously resolved indicating that treatment with benign neglect was successful. The pathogenesis of periostitis ossificans is likely to be multifactorial and the mandibular bone of young, large breed dogs appears to be intrinsically predisposed. Trauma, occlusal forces, and foreign bodies are considered risk factors in the development of MPO. In this case report, trauma from a previous bite wound when the dog was 9 weeks old was a risk factor for this dog in developing MPO.

The stability of rotor systems under large disturbances is often a concern in the design process of rotating machinery. Under this condition, rotor systems show significantly different dynamic behaviors from linear systems. This paper proposes a method for determining rotor system stability under large disturbances. Equivalent stiffness and damping coefficients are defined and a linear system is constructed equivalent to the original system from an energy perspective, so as to indirectly determine the stability of the original system. The influence of large disturbances is described by the oil film boundary migration effect. The proposed method is verified by directly solving the nonlinear dynamic equations. The results show that the method proposed gives results consistent with the direct solving method, while avoids solving the divergent process, resulting in lower computational costs. Furthermore, this paper investigates the effects of several factors under large disturbances in rotor systems with the proposed method. This work may be helpful in qualitative analysis of rotor stability under large disturbances.
Resistance to economic exploitation or religious oppression? A sociomaterial analysis of the agency of Muslim food-delivery workers facing algorithmic management
Authors: Gaillard Hugo , Galière Sophia
Published: November 2024

This qualitative case study examines food-delivery platforms in France in order to reveal how gig workers, lacking traditional employment protections and collective bargaining, rely on informal community mechanisms to develop collective agency that is closely linked to the materiality of platforms. Drawing upon sociomaterial theory and the concept of affordance, our results show that religious affiliation plays a crucial role in the actualization of algorithmic management artifacts by Muslim migrant workers and leads to a sense of emancipation and reconciliation between their religious and work identities. Religious communities, often overlooked or avoided by traditional organizations, act as mediators in the gig economy. Because it uses “ post-diversity” organizational practices that are indifferent to marginal socio-demographic categories, the gig economy provides workers with material, emotional, and informational resources that facilitate identity agency and prioritize it over algorithmic management. The present study contributes to the literature on platform work by illuminating the intricate duality of agency experienced by Muslim migrant workers in the food-delivery sector and developed through community-built resources. It highlights the prioritization of freedom from religious oppression in the labor market over economic considerations, which leads to the acceptance of exploitative working conditions and peer control.
Integrating trace data into interviews: Better interviews, better data
Authors: Pierce-Grove Ri , Watkins Elizabeth Anne
Published: November 2024

In this paper, we present a transnational case study on binge-watching and media habits. The contributions of this paper are two-fold. The first contribution is methodological, proposing ‘data-prompted interviewing’, a variant of trace interviewing. Participants’ own trace data is used to help them recall their own behavior in more detail, which in turn enables them to identify gaps or flaws in trace data records. This case study, which includes sixty interviews in platform logs from YouTube, Netflix and a large self-tracking service, provides evidence that ‘data-prompted interviewing’ yields robust results. Using data to prompt interviewees’ memories substantially improved their recall, and interviewees’ insights into platform data substantially improved its interpretation. The second contribution of this case study is theoretical, engaging with calls for reflexivity in media studies by empirically embracing Jenssen’s idea of dual ‘data movements’ and operationalizing reflexivity into concrete methods. Looking at the platform logs with the interviewee revealed patterns and habits in watching behavior which an interview alone would have entirely missed. But interviews also revealed quirks in the platform data which would have completely misled a researcher working with platform logs alone. The combination produces more insightful and robust research results for both ‘big data’ and ‘small data’ approaches. Recent data protection laws, which give millions of people the right to access their own trace data from platforms, make this approach practical for a wide range of questions in media studies. We propose that media studies scholars embrace reflexivity as not just theory but method, and through data-prompted interviews, fully embrace how the field affects research, and how research affects the field.
Using the Design Thinking Approach for a University Health Promotion Program: A Pilot Study

University wellness programs often employ health campaigns to promote awareness and engagement in health behaviors. However, with limited resources, it is challenging to develop and test health campaign materials in a timely manner. The Design Thinking Approach (DTA) provides a promising strategy for developing materials in a quicker, less expensive way compared to traditional methods. This pilot study examined the feasibility and short-term impact of implementing the DTA to develop a self-care campaign at a university to reach students on campus. University peer health educators and staff completed a 5-session DTA workshop to learn how to apply the DTA to develop and test a self-care campaign. Feasibility of the approach was conducted by having workshop participants rate the acceptability and practicality of the process. To examine the short-term impact, the self-care campaign was compared to an existing mental health campaign. Results from the feasibility analysis indicated that the participants responded well to the approach and found it to be overall beneficial. Results also revealed that the self-care campaign had a greater number of event attendees compared to the existing mental health campaign. However, the reach on social media was similar, but slightly higher, for the existing mental health campaign. No significant difference in perceived effectiveness score was found. Results provide evidence for the potential for the DTA to be a feasible and efficient tool for testing health campaign ideas. However, more extensive testing is needed to understand its impact long-term and which feedback methods (e.g., interviews and surveys) are most useful.
An introduction to creative health
Authors: Jenkins Catherine , Lambert Kathryn , Mackintosh Will
Published: November 2024

There is growing evidence that arts and creativity have a role to play in both healthcare and population health. Incorporating arts into healthcare requires a shift in mindset from the traditional medical model of healthcare and structures and systems in place to support this transformation. This article provides an introduction to creative health. Through creative arts, there is an opportunity to improve individual and population health, reduce health inequalities and enrich communities. Creative arts can additionally support practitioner health and wellbeing. By providing an overview of the evidence base we hope that trainees will feel confident in recommending creative arts to their patients as well as understand how this can benefit their own wellbeing and that of the wider community around them.

Published: November 2024

Purpose:

Radial neck fractures in children are rare, representing less than 1% of all pediatric fractures. While conservative treatments are often sufficient, displaced fractures may require closed or open reduction. The Metaizeau technique is widely accepted for closed reduction and internal fixation. This study aims to assess the long-term functional and radiological outcomes of this technique and identify any complications that may arise.

Methods:

This retrospective study analyzed 22 pediatric patients treated with the Metaizeau technique for proximal radius fractures between 2005 and 2018. Data on demographics, preoperative radiographs, and postoperative complications were reviewed. Outcomes were evaluated using radiographic and functional measures, including grip strength, the Mayo elbow performance score (MEPS), and the Tibone and Stolz classification.

Results:

The mean age at the time of injury was 9.9 years, with a mean follow-up period of 139 months (range: 72–213 months). Patients were classified as Judet type 3 ( n = 9), type 4a ( n = 9), or type 4b ( n = 4). The functional outcomes showed a mean MEPS score of 99 (range: 90–100), with 86% of patients achieving excellent results according to the Tibone and Stolz classification. Excellent outcomes were recorded in 100% of type 3, 77.7% of type 4a, and 75% of type 4b cases. Documented complications included one case of radioulnar synostosis and two cases of heterotopic ossification.

Conclusions:

The Metaizeau technique represents an efficacious treatment option for pediatric radial neck fractures, offering favorable long-term functional and radiological outcomes with a low complication rate. Long-term follow-up data further support the reliability of this technique.

Types of Studies:

Level IV.
