Abstract

Context
Assisted reproductive technology (ART) is associated with increased metabolic risks in offspring. The effect of high maternal estradiol (E2) levels during early pregnancy on the glucose metabolism of offspring remains unclear.

Objective
This work aimed to evaluate glucose metabolism in children conceived via in vitro fertilization (IVF) and to assess whether high E2 exposure during early pregnancy is associated with metabolic alterations.

Methods
This retrospective analysis included 500 singletons aged 3 to 10 years born after fresh embryo transfer (ET) (n = 200), frozen ET (n = 100), and natural conception (NC) (n = 200) from a university hospital. Children underwent anthropometric measurements and examinations for fasting glucose, insulin, and lipid levels. A mouse model of high E2 exposure during early pregnancy was established to study glucose and insulin tolerance, and insulin secretion.

Results
Compared with NC, children born after fresh ET showed higher fasting glucose/insulin levels, increased insulin resistance, and higher incidence of impaired fasting glucose, which might be associated with higher maternal E2 levels. Frozen ET showed intermediate results. In mice, offspring exposed to high E2 levels during gestation exhibited impaired glucose/insulin tolerance and defects in insulin secretion.

Conclusion
High maternal E2 levels in early pregnancy are associated with altered glucose metabolism and increased metabolic risks in IVF-conceived children. Further studies are needed to elucidate the underlying mechanisms.
“Unquestioned Citizenship”: History, Poetry, and Black and Native Military Service in Hampton Institute’s Southern Workman
Authors: Serafini Sidonia 
Published: October 2024

Abstract
This article explores how Black race histories, Native American traditionary histories, and tribute poems published in Hampton Institute’s Southern Workman (1872–1939) used military service as an imaginative foundation for thinking about citizenship beyond legal meanings. In race and traditionary histories, writers make visible the sacrifices of Black and Native soldiers that had been overlooked in official accounts of wars throughout US history. Writers also transform these histories’ commemorative aim into tribute poems, which accomplish similar work by recognizing publicly, through imaginative verse, Black and Native military service. These writers share a hope that military service might usher in the benefits of formal citizenship. But that hope is accompanied by a sense of skepticism, in that wartime did not always yield a completely united American front. With such contingencies in mind, writers use the act of military service as inspiration for the act of writing into the historical and literary record the legacy of Black and Native commissioned and noncommissioned men and women, bestowing upon each other a sense of “unquestioned citizenship” that the nation would not.
Clinical Measures Associated with Subsequent Injury after Adolescent Concussion: A Prospective Cohort Study
Authors: SMULLIGAN KATHERINE L. , CARRY PATRICK , WINGERSON MATHEW J. , DONAHUE CATHERINE , WILSON JULIE C. , HOWELL DAVID R. 
Published: October 2024

ABSTRACT

Purpose
This study aimed to examine associations between clinical measures (self-reported and clinician administered) and subsequent injury rates in the year after concussion return to play (RTP) among adolescent athletes.

Methods
We performed a prospective, longitudinal study of adolescents ages 13–18 yr. Each participant was initially assessed within 21 d of concussion and again within 5 d of receiving RTP clearance from their physician. Participants completed self-report measures: the Pittsburgh Sleep Quality Index and Tampa Scale of Kinesiophobia, and clinician-administered measures: single- and dual-task tandem gait and reaction time (RT; simple and clinical) assessments. They then completed monthly surveys for a year after RTP, which assessed exposure to injury (sport participation) and subsequent injuries (musculoskeletal or concussions) sustained. We used Poisson regression models to calculate injury rate ratios with the number of subsequent injuries sustained as the outcome, adjusted for RTP clearance time and competitive exposures for each measure.

Results
Forty-one participants were included (age = 15.5 ± 1.3 yr, 56% female, 9.6 ± 4.6 d postconcussion; 38.0 ± 31.5 d to RTP). A higher injury rate per athletic exposure was observed for simple RT ≥ 505 ms versus <505 ms (injury rate ratio = 2.96, 95% confidence interval = 1.41-6.60, P = 0.005). Injury rates did not significantly differ by Pittsburgh Sleep Quality Index or Tampa Scale of Kinesiophobia scores, single/dual-task tandem gait time, or clinical RT.

Conclusions
Simple RT may be one risk factor that is associated with higher rates of subsequent injury after adolescent concussion. A simple RT measure incorporated into a comprehensive concussion RTP assessment may identify some individuals at higher risk of subsequent injury in the year after concussion, although further research is needed to better understand this relationship.
Ο ρόλος και οι επαγγελματικές δραστηριότητες των παιδαγωγών πρώιμης παιδικής ηλικίας
Authors: Rentzou Konstantina 
Published: October 2024

Τα τελευταία χρόνια, η παιδαγωγική πρακτική που απευθύνεται σε βρέφη και μικρά παιδιά τυγχάνει αυξημένης προσοχής σε επίπεδο πολιτικής. Ωστόσο, λίγα είναι γνωστά για το τι εμπεριέχει η παιδαγωγική πρακτική για αυτή την ηλικιακή ομάδα και πώς οι παιδαγωγοί βλέπουν τον ρόλο και την επαγγελματική τους ταυτότητα. Η παρούσα έρευνα φιλοδοξεί να καλύψει το ερευνητικό κενό σχετικά με το τι συνεπάγεται η επαγγελματική ταυτότητα και το έργο των παιδαγωγών πρώιμης παιδικής ηλικίας και να αναδείξει τις επαγγελματικές δραστηριότητες και τις παιδαγωγικές πρακτικές που υιοθετούνται στις τάξεις που φιλοξενούν παιδιά ηλικίας έως τριών ετών. Συνάμα, στόχος της έρευνας είναι χαρτογραφήσει τις απόψεις των παιδαγωγών για τη θέση της εκπαίδευσης και της φροντίδας στις τάξεις στις οποίες φιλοξενούνται παιδιά ηλικίας έως τριών ετών. 51 Έλληνες παιδαγωγοί πρώιμης παιδικής ηλικίας απάντησαν σε ένα διαδικτυακό ερωτηματολόγιο που περιελάμβανε ερωτήσεις κλειστού και ανοιχτού τύπου. Τα αποτελέσματα αποκαλύπτουν ότι ο ρόλος των παιδαγωγών είναι πολύπλοκος και πολύπλευρος και ότι οι παιδαγωγοί αφιερώνουν τον περισσότερο χρόνο τους σε πρακτικές εκπαίδευσης και φροντίδας παρά στη διαχείριση. Επιπλέον, τα αποτελέσματα υπογραμμίζουν ότι αν και οι συμμετέχοντες δεν αποδέχονται στο σύνολό τους τη συνύπαρξη της εκπαίδευσης και της φροντίδας στις τάξεις που φιλοξενούν παιδιά ηλικίας μέχρι τριών ετών, η φροντίδα κινείται πέρα από τους στενούς ορισμούς που περιλαμβάνουν ρουτίνες, σε μια ευρύτερη εικόνα της φροντίδας που περιλαμβάνει εκπαιδευτικές και σχεσιακές πτυχές. Τα αποτελέσματα υπογραμμίζουν την ανάγκη να διερευνηθούν περαιτέρω οι φωνές των παιδαγωγών πρώιμης παιδικής ηλικίας σχετικά με τον ρόλο, την επαγγελματική ταυτότητα και την εργασία τους.
Siła powieści – osiem dekad później
Authors: Korwin-Piotrowska Dorota 
Published: October 2024

Tytuł tekstu nawiązuje do słynnej rozprawy Rogera Caillois z 1942 r. pt. Siła powieści (Gdańsk: Wydawnictwo UG, 2008; oryg. Puissances du roman. Paris: Editions du Sagittaire, 1942). Autorka artykułu próbuje odpowiedzieć na pytanie, dlaczego prognozy wyczerpania się tego gatunku się nie spełniły oraz jak można obecnie klasyfikować powieść, unikając przy tym zbyt wąskiego jej rozumienia. Nawiązuje przy tym zarówno do biologicznej taksonomii i kategorii kladu, jak i do zjawiska anamorfizmu w malarstwie. Rozważa też rolę powieściowej fikcji w ‘fikcjonalizacji życia’ i upowszechnieniu się kategorii narracji we współczesnej kulturze. Pokazuje przy tym – na przykładach z twórczości Olgi Tokarczuk (Empuzjon. Kraków: Wydawnictwo Literackie, 2022), Jacka Dukaja (Imperium chmur. Kraków: Wydawnictwo Literackie, 2020), a także Tomasza Różyckiego (Ijasz. Kraków: Wydawnictwo Literackie, 2021; Złodzieje żarówek. Wołowiec: Wydawnictwo Czarne, 2023) – jak nowoczesna polska powieść łączy różne sprzeczności, m.in. realizm i fantastykę, kulturę wysoką i popkulturę, powagę oraz zabawę.
Między Toruniem i Borysławiem

Published: October 2024

Posiłkując się metodologią geopoetyki, komparatystyki i antropologii kulturowej, autorka analizuje prozę Zdzisława Wróbla (1925–2007). Koncepcja autobiogeografii (Rybicka) oraz autotanatografii (Ubertowska) dają możliwość wpisania prozy Wróbla w nowe konteksty (re)interpretacyjne. W centrum zainteresowania znajdują się powieści i opowiadania, w których wyraźnie funkcjonują pewne schematy autobiogeograficzne i autotanatograficzne, semiotyczną oś których stanowi ryt przejścia i jego wymiary – egzystencjalny, przestrzenny, aksjologiczny. Badaczka pokazuje, że Wróbel eksperymentuje z różnymi tendencjami gatunkowymi powieści migracyjnej. Używając typologii Bogusława Bakuły, mówić można o zastosowaniu schematów kombatancko-repatriacyjnych (Dlaczego?), romantyczno-misjonarskich (Dlaczego?), socjo-historycznych (Szczeble, Inauguracja) i w specyficzny sposób ujętych westernowo-przygodowych (Eldorado). Badaczka zwraca też uwagę na to, że bohaterowie Wróbla borykają się z traumatycznym doświadczeniem powojennej rzeczywistości (oswajanie poniemieckiego) jak również z traumatycznym doświadczeniem przeszłości (świadkowie i ofiary Zagłady). Czują ogromną ulgę, gdy mogą z tego świadectwa się „wyspowiadać”.
Can Improvements to Mobile Internet Service Help Reduce Digital Inequality? An Empirical Analysis of Education and Overall Data Consumption
Authors: Nattamai Kannan Karthik Babu , Overby Eric , Narasimhan Sridhar 
Published: October 2024

Quality internet access is critical to participating in contemporary society. Unfortunately, many households—particularly those of low socioeconomic status and/or those in rural areas—do not have quality internet access. Some have no access, whereas others are reliant on their mobile data plans for internet access (i.e., they are “smartphone dependent”). This generates inequality in internet access and use. Given the smartphone dependence of many disadvantaged households, we explore whether improvements to mobile internet service can help reduce digital inequality. We focus on a specific improvement: access to unlimited mobile data. For access to unlimited data to help reduce digital inequality, it must generate larger data consumption increases for disadvantaged households than for advantaged ones, including for data likely to enhance welfare, such as online education content. It is not obvious that this will be the case. Accordingly, we use detailed subscriber-level data from a major telecommunications company to examine changes in the consumption of education and other content after subscribers switch to unlimited mobile data plans. We find that although all subscribers increase their consumption, the increases are significantly larger for disadvantaged subscribers, both for overall content and for education content. This is an important finding given that identifying programs that generate disproportionate data consumption increases for disadvantaged households—including for education and other “enhancing” content—is a necessary step for reducing digital inequality.

Epidemiology and regional variance of traumatic peripheral nerve injuries in Sweden: A 15-year observational study
Authors: Magnéli Martin , Axenhus Michael 
Published: October 2024

Introduction
Traumatic peripheral nerve injuries pose significant challenges to healthcare systems and individuals, affecting sensory function, causing neuropathic pain, and impairing quality of life. Despite their impact, comprehensive studies on the epidemiology and regional variance of these injuries are scarce. Understanding the incidence, trends, and anatomical distribution of such injuries is essential for targeted interventions and resource allocation.

Methods
This observational study utilized register-based data from the Swedish National Patient Register covering the period from 2008 to 2022. Incidence rates, trends, and anatomical distribution of traumatic peripheral nerve injuries were analyzed using descriptive statistics, Poisson regression modeling, and regional comparisons.

Results
Higher incidences of peripheral nerve injuries were observed among men compared to women across all age groups. The hand and wrist were the most commonly affected sites. Regional variations in incidence rates were evident, with some regions consistently exhibiting higher rates compared to others. Notably, a decreasing trend in injuries was observed over the study period.

Conclusion
This study underscores the importance of targeted interventions and preventive strategies, considering sex, age, and regional disparities. Further research incorporating individual patient-level data is warranted to enhance our understanding and inform tailored interventions to reduce the burden of these injuries.

Timed Automata und zeitliche Anomalien in Wissensgraphen von automatisierten Produktionsanlagen
Authors: Westermann Tom , Gill Milapji Singh , Fay Alexander 
Published: October 2024

ZusammenfassungDie modellbasierte Identifikation von Anomalien ist ein weit verbreiteter Ansatz, um Abweichungen vom erwarteten Verhalten eines Cyber-Physical Production Systems (CPPS) zu erkennen. Da die manuelle Erstellung dieser Modelle ein zeitaufwändiger Prozess ist, ist es vorteilhaft, sie aus Daten zu lernen und in einem generischen Formalismus wie z. B. Timed Automata darzustellen. Die Interpretation solcher Modelle, und somit auch der identifizierten Anomalien, wird jedoch aufgrund fehlender Kontextinformationen erschwert. Dieser Beitrag zielt darauf ab, die modellbasierte Anomalieerkennung in CPPS zu verbessern, indem der gelernte Timed Automaton mit einem formalen Wissensgraphen über das System kombiniert wird. Hierdurch werden sowohl das Modell als auch die identifizierten Anomalien mit eindeutiger Semantik in einer gemeinsamen Wissensbasis beschrieben, um den Anlagenbetreibern eine einfachere Interpretation des Modells und der identifizierten Anomalien zu ermöglichen. Darüber hinaus präsentieren die Autoren eine Ontologie der erforderlichen Konzepte und Beziehungen. Der Ansatz wurde an einer prozesstechnischen Mischanlage validiert. Es konnte gezeigt werden, dass die Interpretierbarkeit der Anomalien und des Automatenmodells durch den generierten Wissensgraphen gesteigert werden konnte.
Downstream Competition and Upstream Innovation: Theory and Evidence from China
Authors: Dai Jing , Liu Guanchun , Ye Ziqi , Mao Haiou , Ye Yongwei 
Published: October 2024

Abstract
Competition is the catalyst of corporate innovation, which is the foundation of a country’s core competitiveness. From the view of vertical industrial chain, this paper examines how downstream competition affects upstream firms’ innovation output. Given innovation helps reduce the production cost of each product, increasing demand of intermediate products caused by downstream competition enhances the marginal revenue of upstream firms’ innovation, thus leading to an innovation incentive effect. To identify causality, we utilize China’s WTO accession, a quasi-natural experiment, to calculate downstream competition combined with import tariff reduction and input-output table, and then run a difference-in-difference regression. Using the data of Annual Survey of Industrial Firms and State Intellectual Property Office, our results find that downstream competition has a significantly positive impact on upstream firms’ innovation, and this effect is more pronounced in firms with less industry competition, greater initial innovation capacity and weaker financial constraints. Moreover, the number of firms, the degree of industry competition and the scale of intermediate products in the downstream sector increase, confirming the market size channel. In sum, our findings document that downstream competition can motivate upstream firms to innovate through vertical industrial chain, providing some useful insights for China to build a fair market competition environment and promote innovation-driven growth regime.
Energy Price Fluctuation and Real Estate Market Risk Prevention—Empirical Evidence at the Prefecture-Level City Level in China
Authors: Wang Zhenxia , Yan Bingqian , Wang Lei 
Published: October 2024

Abstract
The impact of energy price fluctuation on the macro economy is a hot issue that is continuously concerned by the academic community, but few literature have paid attention to the impact of energy price fluctuation on housing price and the financial risks that may arise. Based on the data of cities at and above the prefecture level in China, this paper empirically examines the impact of energy price fluctuation on the price fluctuation of the domestic real estate, and analyzes its influencing mechanism and transmission pathways. The results show that changes of energy price will significantly affect the fluctuation of domestic real estate price, and it is more obvious in large cities and megacities. Energy price affect the demand for housing through changes of interest rate levels on the one hand, and the supply of the real estate market through the cost of housing construction on the other hand, which leads to housing price fluctuation. After a series of robustness tests, the results are still valid. At the same time, the effect is asymmetric, that is, higher energy price increases the fluctuation of house price, but the impact of falling energy price is not significant. Therefore, when preventing real estate market risks, energy price should be considered as a forward-looking indicator to focus on, and the regulation and control policies of the real estate market should be scientifically formulated. This paper not only provides a new perspective on the mechanism of housing price formation, but also enriches the research on the interconnection between energy and financial markets.
The Impact of Global Value Chain Embedment on Energy Conservation and Emissions Reduction:Theory and Empirical Evidence
Authors: Bai Junhong , Yu Xuewei 
Published: October 2024

Abstract
An in-depth investigation into the effect of embedment in global value chain (GVC) on energy conservation and emissions reduction is of great significance for scientifically assessing the environmental impact of GVC participation, and promoting high-quality development in China. This paper incorporates GVC embedment, energy consumption and carbon emissions into the same analysis framework for the first time. Based on the WIOD database, this paper theoretically and empirically examines the impact and mechanism of global value chain embeddedness on carbon emission reduction from two dimensions: energy consumption intensity and energy consumption structure. The study found that GVC embedment significantly reduced the industry’s carbon emission intensity; developing economies’ embedment in GVC helped reduce their carbon emission intensity, while the effect was not obvious in developed economies. GVC embedment had a significant inhibitory effect on the carbon emissions in both upstream and downstream industries, but not conducive to carbon reduction of low-tech manufacturing. The mechanism test shows that the GVC embedment not only exhibits the dual effects of energy conservation and emissions reduction, but also has a significant impact on carbon emissions by reducing the energy consumption intensity and improving the energy consumption structure.
In Search of a Sinful Pun: A Granular Analysis of Q 2:58–59
Authors: Gyllenhaal David , Zuckier Shlomo 
Published: October 2024

Abstract
This paper offers a new reading of Q 2:58–59 by way of Muqātil ibn Sulaymān’s Tafsīr and its use of the Hebrew Bible and Jewish or possibly Christian traditions. While the scholarly study of the Qurʾān in its late antique context has often been ambivalent toward medieval Arabic tafsīr, this paper uses the testimony of the tafsīr corpus on a single mysterious passage to reconstruct a plausible meaning in its original Qurʾānic milieu and shed light on the exegetical intimacies of Jews, Christians, and Muslims in the first Hijri centuries.
Q 2:58–59 contain a puzzling pericope about God punishing the Israelites because they substituted one word, which God had commanded them to say, with another. The word God commanded them to say, ḥiṭṭa, does not represent any Arabic word that makes good sense in context. The word they substituted is never specified. Later Arabic exegetes were thus puzzled by the passage and proposed many different solutions. The paper closely analyzes Muqātil ibn Sulaymān’s reading of the relevant passage in light of biblical intertexts and Jewish or Christian traditions, yielding an interpretation of this passage with reference to a perfidious pun on the words for “sin” and “grain” that works in Aramaic or possibly Hebrew, but not in Arabic.
