Advancing culturally relevant pedagogy in college chemistry
Authors: Cooper Destinee J. , Voigt Matthew 
Published: November 2024

Abstract
There is increasing emphasis on incorporating complex global challenges such as sustainable development and environmental justice in college chemistry instruction. Addressing these issues requires a community of engaged citizens who are empowered to enact change in their communities and value diverse perspectives. Culturally relevant pedagogy (CRP) is a framework that may support college chemistry faculty in integrating these social justice aims while also advancing equity within their own classrooms. However, college chemistry instructors’ knowledge and implementation of CRP remains understudied. This research explores how college chemistry instructors (n = 6) from different institutions across the United States describe and operationalize CRP. Thematic analysis of semi-structured interviews indicates that the instructors in this study are flexible in their teaching approach, cultivate a classroom community of collaboration and belonging, and affirm that all students can be successful in chemistry. These practices are foundational elements of CRP, but they must also be coupled with knowledge of students’ cultural backgrounds and awareness of sociopolitical issues that impact students. A framework that considers the context of college chemistry is proposed to support instructors’ adoption of all of the tenets of CRP. Future work will further develop and examine the use of our framework for chemistry faculty development.
Transition space: navigating dilemmas between mainstream and minority language classrooms
Authors: Kosner Lukas Espenes 
Published: November 2024

Abstract
From policymaking to classroom practices, educational language policy implementation is a complex process filled with a cacophony of voices. This article examines policy implementation as it unfolds in micro-level transitions between mainstream classrooms and lessons in Sámi, Kven, or Finnish as a second language (SKF) in Norway. In such situations, SKF pupils need to leave their mainstream classes to receive their language instruction. To examine these transitions, I draw primarily from ethnographic data (e.g., classroom observations and semi-structured interviews) collected over several months in public schools in a town in Northern Norway. The findings suggest that organizational circumstances construct an in-between space, which I refer to as transition space, in which classroom actors can or need to negotiate and make choices about which of the theoretically co-available classes/activities will be chosen at which times. Such choices involve dilemmas and consequences on different scales. In this study, (1) I demonstrate how (non)movements between mainstream and SKF classes are made in time and space, and (2) I propose transition space as a new conceptualization for researching micro-level transitions in educational settings.
Macroeconomic and Fiscal Consequences of Climate Change in Latin America and the Caribbean
Authors: Titelman Daniel , Hanni Michael , Pérez Benítez Noel 
Published: November 2024

Abstract
Climate change poses a significant challenge for Latin America and the Caribbean, exposing its vulnerabilities to hydrometeorological shifts and rising temperatures that threaten economic stability. We examine the macroeconomic consequences of climate change through the lens of six distinctive country cases. Our results suggest that compensating for the drag on economic growth caused by climate change would require public and private investments of 5.3 % of GDP to 10.9 % of GDP per year. Faced with existing fiscal constraints and restrictive financial conditions, we explore the macrofiscal implications of an investment push in line with the Nationally Determined Contributions (NDCs). Our results suggest that front-loaded public adaptation investments would improve growth over the medium term, although not fully compensating for climate losses. However, resulting public debt trajectories would become untenable in most countries. We find that a key factor for a fiscally sustainable NDC investment push is the financial costs that countries face when issuing sovereign debt. Debt sustainability could be significantly improved if countries could finance their climate investments at lower cost or concessional terms.

Published: November 2024

Abstract
This paper considers homogeneous equation of convolution type of the first kind on a finite interval.
An analogue of the well-known Titchmarsh theorem on supports in convolution is obtained. The results of the work were obtained under the condition that the kernel function in the integral operator is equal to zero in the neighborhood of zero.
Numerical analysis on impedance characteristics of dual wavelength quantum cascade lasers
Authors: Panchapakesan Ashok , M. Ganesh Madhan 
Published: November 2024

Abstract
This article reports the computation of impedance in dual wavelength quantum cascade lasers (DW-QCLs) for the first time. The DW-QCL operates at two wavelengths 10.5 μm and 8.9 μm and contains 48 stages. The injected current decides the single mode (emission at 10.5 μm) or bi-mode (emission at both wavelengths) lasing characteristics of the device. The device exhibits a higher impedance till Ith
(1) since lasing has not begun and sharply reduces from 18.8 Ω (at 0.5 Ith
(1)) to 1.2 Ω at Ith
(1) at dc conditions. Under pre-threshold lasing region, the device exhibits a larger impedance and is inductive in nature. The maximum magnitude of impedance in this region is 18.82 Ω when the device is injected with 0.5Ith
(1) and it reduces to 10.45 Ω at 0.9Ith
(1). In the lasing region (single and bi-mode), it is clearly visible that there are regions of capacitive reactance and inductive reactance occurring at different bands. The maximum impedance offered by the device over a wide range of frequencies is computed for different modes of operation. The analytical part to derive the equation of impedance of the DW-QCL involves the rate equations in frequency domain, the apparent substitution and simplification thereafter. The computation of impedance is necessary for matching the laser driver with the DW-QCL for efficient operation at higher operating frequencies.

Published: November 2024

Abstract
The North African sengi (Petrosaltator rozeti syn. Elephantulus rozeti) is a small mammal endemic to the Maghreb area, and is one of the least studied mammals in North Africa. Little is known about its status, habitat preference, and distribution across large areas of its range. This work provides a detailed geographical and ecological distribution of the species in Tunisia based on 200 surveyed sites throughout the country with 103 positive occurrence records. We also used species distribution modelling to assess the habitat suitability of the species. P. rozeti showed a heterogeneous bioclimatic niche, with a presence in the semi-arid, arid and Saharan bioclimatic zones. But the species’ distribution seems to be limited to the main mountain ranges of Tunisia. This was also confirmed by habitat suitability modeling where the elevation was the most informative predictor variable. Our work also show some first recorded ecological traits, confirms the rock-dwelling specialist nature of the species and debate its endemism to mountain ecosystems.
First record of the spotted hyena Crocuta crocuta in Egypt during the past 5,000 years
Authors: Nagy Abdullah , El-Kholy Said , Soultan Alaaeldin , Attum Omar 
Published: November 2024

Abstract
An individual of spotted hyena Crocuta crocuta was killed by local people in Elba Protected Area, South-East Egypt in winter of 2024. This record constitutes the first record of the species in contemporary Egypt since its extinction over 5,000 years ago. The possibility of increased rainfall and grazing practices creating a corridor for hyena dispersal from neighboring Sudan was investigated. The record is 500 km north of the known range of the spotted hyena.
What makes a super influencer? Testing the origin of fame theory in China
Authors: Shao Yihan , Willnat Lars 
Published: November 2024

Abstract

Study purpose
Social media influencers in China have significantly influenced public political and social attitudes and behaviors. Based on the origin of fame theory, this study explores which type of influencers – originals, celebrities, or journalists – are most effective in driving changes in their followers’ attitudes and behaviors.

Methodology
An online experiment used a 3 (type of influencer: original, celebrity, journalist) × 2 (message context: policy-based, social modeling) design. A total of 627 responses were collected to assess how participants evaluate social media influencers and to examine their attitudes and behaviors toward the issues supported by these influencers.

Main findings
The findings reveal that the effects of social media influencers depend on both their identity and the type of message they promote. Journalist influencers have the greatest effects on participants’ attitudes toward policy-based messages compared to original and celebrity influencers. By contrast, original influencers are more effective at shaping attitudes when sharing social modeling messages. Additionally, the study shows that journalist influencers are perceived to have greater expertise than other influencers, regardless of the message context.

Social implications
This study shows that identity and message context jointly determine the influence of social media influencers on promoting nonprofit campaigns.

Practical implications
Communicators can apply the findings of this study to select appropriate social media influencers by considering both the origin of influencers’ fame and the context of the message they are promoting.

Originality/value
This study emphasizes the power of social media influencers to promote nonprofit campaigns and identifies the conditions that can enhance their effectiveness.
Cross-sectional analysis of blood leukocyte responsiveness to interleukin-10 and interleukin-6 across age and physical activity level
Authors: Islam Hashim , Boultbee Jordan , Jackson Garett S. , Mui Alice L. , Little Jonathan P. 
Published: November 2024

Abstract

Objectives
To determine how the anti-inflammatory actions of interleukin-10 (IL-10) and IL-6 differ across age and physical activity levels.

Methods
Using a cross-sectional design, fasted blood samples were obtained from younger physically inactive (YI: n=10, age: 22.7 ± 3.7 years, BMI: 24.8 ± 4.8 kg/m2, <150 min of weekly moderate-to-vigorous physical activity [MVPA]), younger highly active (YA: n=11 varsity cross country running athletes, 20.7 ± 2.7 years, 21.1 ± 1.8 kg/m2, >300 min of weekly MVPA), and older highly active (OA: 12, 56.0 ± 10.3 years, 22.8 ± 3.2 kg/m2, >300 min of weekly MVPA) individuals and analyzed for leukocyte counts, IL-10 and IL-6-related signaling, and cytokine secretion ex vivo.

Results
Total white blood cells and monocytes were similar between groups (p=0.8) but YA and OA had lower lymphocyte counts than YI (p<0.01). The ability of IL-10 (1 ng/mL) to phosphorylate signal transducer and activator of transcription 3 (STAT3) in CD14 monocytes was greater in YA vs. YI (p<0.03) despite YA having lower IL-10 receptor expression (p<0.01). IL-6 (10 ng/mL) mediated STAT3 phosphorylation in CD4 lymphocytes was higher in OA compared YI (p<0.01), with a similar tendency observed for YA vs. YI (p=0.08). Despite enhanced responsiveness of STAT3 to IL-10/6 in active individuals, the ability of IL-10/6 to inhibit tumor necrosis factor-alpha (TNF-⍺) secretion from lipopolysaccharide-stimulated whole-blood was similar between groups.

Conclusions
Highly active younger and older individuals demonstrate enhanced IL-10- and IL-6-mediated activation of immune cell STAT3. Although the ability of IL-10/6 to inhibit TNF-⍺ secretion appeared unimpacted by activity level, anti-inflammatory cytokine actions were preserved in older active individuals.
Proleptic objects as complex-NPs
Authors: Gluckman John 
Published: November 2024

Abstract
Proleptic (or prothetic) objects (Majaliwa remembered about Samson that he’s sick) present a particular puzzle because they appear to instantiate an unconstrained cross-clausal dependency between the proleptic object (Samson) and a correlate (he). The current analytical approach to prolepsis is relies on a syntactic mechanism of treating the embedded clause as a predicate, derived by merging a null operator which unselectively binds the correlate. This approach faces a number of known empirical challenges. Moreover, this work does not meaningfully engage with any of the recent semantic innovations in our understanding of embedded clauses (Kratzer 2006. Decomposing attitude verbs. Available at: http://semanticsarchive.net/Archive/DcwY2JkM/attitude-verbs2006.pdf). I offer an alternative to the CP-predicate approach, adopting three (semi-)independently motivated ideas concerning (i) the syntax of cross-clausal dependencies in Lohninger et al. (2022. From prolepsis to hyperraising. Philosophies 7(32)), (ii) the semantics of embedded clauses in Kratzer (2006. Decomposing attitude verbs. Available at: http://semanticsarchive.net/Archive/DcwY2JkM/attitude-verbs2006.pdf)/Moulton (2009. Not moving clauses: Connectivity in clausal arguments. Syntax 16(3). 250–291), and (iii) the semantics of about in Rawlins (2013. About about. Proceedings of SALT 23. 336–357)/Onea and Mardale (2020. From topic to object, grammaticalization differential object marking in Romanian. Canadian Journal of Linguistics/Revue Canadienne de Linguistique 65(3). 350–392). I argue that proleptic objects are complex-NPs, roughly, the thing about Samson. The somewhat particular properties of prolepsis are natural consequences of these combined ideas. I further present empirical evidence from Japanese that the complex-NP analysis is on the right track. This analysis deepens our understanding of prolepsis by including both semantic and syntactic factors.
Specifier-to-head reanalysis: evidence from mandarin and Cantonese
Authors: Wang Shuyan 
Published: November 2024

Abstract
Mandarin numeral phrases display two characteristics. First, the numeral yi ‘one’ differs from other numerals in many respects. Second, classifiers can appear without any overt numerals, resulting in Cl-N phrases (e.g., ben shu ‘one book’): Cl-N phrases, like numeral phrases with yi ‘one’ (e.g., yi-ben shu ‘one book’), always denote singularity, but also contrast with numeral phrases with yi ‘one’ in various respects like scope. Although some of these patterns have been discussed before (e.g., Cheng, Lisa Lai-Shen & Rint Sybesma. 1998. Yi-wan tang, yi-ge tang: Classifiers and massifiers. Tsing-Hua Journal of Chinese Studies 28(3). 385–412; Chen, Ping. 2003. Indefinite determiner introducing definite referent: A special use of ‘yi ‘one’ + classifier’ in Chinese. Lingua 113. 1169–1184; Huang, C.-T. James. 2015. On syntactic analyticity and parametric theory. In A. Li, A. Simpson & W.-T. Dylan Tsai (eds.), Chinese Syntax in a cross-linguistic perspective. Oxford University Press; Li, Y. H. Audrey & Shengli Feng. 2015. ‘yi’ zi shenglüe de yunlü tiaojian [The prosodic conditions on yi-deletion]. Yuyan Kexue [Linguistic Sciences] 14(1). 1–12; Zhang, Niina Ning. 2019. Complex indefinites and the projection of DP in Mandarin Chinese. Journal of East Asian Linguistics), previous analyses could cover some but not all these observations. This paper provides a unified account for these two puzzles and a number of related issues. It will be argued that due to an ongoing grammaticalization process, Mandarin yi is ambiguous between a numeral and an indefinite article. The grammaticalization of yi is an instantiation of a well-known phenomenon: specifier-to-head reanalysis (e.g., van Gelderen, Elly. 2004. Grammaticalization as economy. John Benjamins Publishing Company; van Gelderen, Elly. 2019. Cyclical changes and problems of projection. In Anne Breitbarth, Miriam Bouzouita, Lieven Danckaert & Elisabeth Witzenhausen (eds.), Cycles in language change. Oxford University Press; Roberts, Ian. 1993. Verbs and diachronic syntax. Dordrecht: Kluwer; Roberts, Ian & Anna Roussou. 2003. Syntactic change: A minimalist approach to grammaticalization. Cambridge: Cambridge University Press). Furthermore, with cross-linguistic evidence from Cantonese, I argue for an intermediate stage of specifier-to-head reanalysis: a functional category starts as a specifier of a phrase; it then adjoins to another head before being reanalyzed as an independent head projecting a separate phrase.

Canonical Literature and Paraliterature: impulses of allegorism and deconstructionism in writing detective stories
Authors: Naujokaitienė Elina 
Published: November 2024

Minette Walters, the queen of British detective Stories, and Luca Di Fulvio, ltalian prose writer and the winner of European Detective, elegantly narrate mysteries of murders, find keys of intimate things and emphasise the genre of Folkner style. How can one effectively manage materials, maintain common sense, and get into the sphere of private offices? Using the characters of lawyers, judges and policemen, the European detective presents an obsessive idea of action for action, analyses social surroundings the space of prisons and establishes new neorealistic stylistics. Because of detective Intrigue, the Great European classical art gets a melancholic character and gives an effect of ensemble. Villainous portraits of ex-terrorists have a sense of metaphysical disappointment and are related to the topic of the search for the Holy Grail. On the basis of confrontative and explicative literature theories (Certeau, Derrida), the article typologises a detective story and analyses its literary genesis from the Middle Ages to Postmodernism.

Drivers of grape berry sugar accumulation in field conditions at local scale
Authors: De Rességuier Laure , Inchboard Lauren , Parker Amber K. , Petitjean Théo , Van Leeuwen Cornelis 
Published: November 2024

The final sugar concentration in grapes is an important parameter for winegrowers as it determines the alcohol content by volume of the final wine, allowing the timing of harvest to be optimised. In this research, a comprehensive dataset spanning seven years and 18 sites located in Saint-Émilion, Pomerol and satellite appellations (Bordeaux, France) was used to assess how growth and developmental factors (berry weight and mid-veraison date, respectively) and environmental factors (vine water status, nitrogen status, and mean air temperature) influence the dynamics of sugar accumulation.
The results of this study highlight the strong influence of mean temperature on the timing of maximum sugar accumulation, the duration of sugar accumulation and maximum sugar concentration in grape berries. Berry weight and the rate of sugar accumulation also appeared to be significant drivers of final sugar concentration. Fast ripening and increased berry weight were associated with lower sugar concentrations. Sites were clustered according to parameters driving sugar accumulation dynamics and mapped at the scale of the study area, in order to link these findings to terroir expression. In this study, vine nitrogen status did not emerge as a significant explanatory variable in any of the models developed to analyse sugar accumulation dynamics and berry weight. A small but significant effect of vine water status on the precocity of the plateau and on berry weight was found.
These results provide a better understanding of the factors that affect the dynamics of sugar accumulation in grape berries, which can help vine growers adapt to climate change. For example, by promoting practices that delay the onset of ripening to shift to a cooler period of ripening through choice of plant material and management practices. Alternatively, this can be done through an increase in berry weight, which lowers grape sugar and therefore wine alcohol concentration, taking care not to excessively alter the skin-pulp ratio to avoid reducing secondary metabolites.
Influenza Vaccination, Household Composition, and Race-Based Differences in Influenza Incidence: An Agent-Based Modeling Study
Authors: Williams Katherine V. , Krauland Mary G. , Harrison Lee H. , Williams John V. , Roberts Mark S. , Zimmerman Richard K. 
Published: November 2024

Objectives. To estimate the effect of influenza vaccination disparities. Methods. We compared symptomatic influenza cases between Black and White races in 2 scenarios: (1) race- and age-specific vaccination coverage and (2) equal vaccination coverage. We also compared differences in household composition between races. We used the Framework for Reconstructing Epidemiological Dynamics, an agent-based model that assigns US Census‒based age, race, households, and geographic location to agents (individual people), in US counties of varying racial and age composition. Results. Influenza cases were highest in counties with higher proportions of children. Cases were up to 30% higher in Black agents with both race-based and race-equal vaccination coverage. Compared with corresponding categories of White households, cases in Black households without children were lower and with children were higher. Conclusions. Racial disparities in influenza cases persisted after equalizing vaccination coverage. The proportion of children in the population contributed to the number of influenza cases regardless of race. Differences in household composition may provide insight into racial differences and offer an opportunity to improve vaccination coverage to reduce influenza burden for both races.

Treatment of a Radiation-Associated Femur Fracture with an Intercalary Endoprosthesis
Authors: Johnson Joshua D. , Al Farii Humaid , Lewis Valerae O. 
Published: November 2024

Case:
A 72-year-old woman with undifferentiated pleomorphic sarcoma of the thigh received neoadjuvant chemotherapy and radiotherapy. She underwent wide resection and was scheduled for prophylactic fixation of the femur. However, prophylactic fixation was deferred secondary to COVID-19 pandemic. Unfortunately, when stepping out of an elevator, she sustained femur fracture. The fracture was treated with a cemented intercalary endoprosthesis. Three-year follow-up reveals stable fixation without any failure.

Conclusion:
Postradiation fractures are challenging. Delayed union, nonunion, and infection are associated with internal fixation. To the best of our knowledge, this is the first report of intercalary endoprosthesis used for primary management of radiation-associated femur fracture.
