Modeling the Impact of Extreme Climate Events on Household Welfare: An Empirical Framework
Authors: Spencer Nekeisha , Strobl Eric 
Published: January 2025

Abstract
This paper provides a review of the main empirical challenges involved in quantitatively estimating the impact of extreme climate events on household welfare at the micro-level. To this end, it first outlines a conceptual framework of extreme climate event damage modeling that can aid in terms of considering the ideal input and damage function requirements to create appropriate proxies. It then considers the use of imperfect versions of these proxies in a general econometric framework designed for typical data contexts, and the implications with regard to the interpretation of the results for the impact on household welfare. Using four extreme climate event type case studies, namely tropical cyclones, flooding, extreme heat, and droughts, the study outlines and discusses their respective challenges within the proposed framework.
Internationalisation patterns of academic spin-offs
Authors: Camelo-Ordaz Carmen , Dianez-Gonzalez Juan Pablo , Franco-Leal Noelia , Sousa-Ginel Elena 
Published: January 2025

Abstract
The aim of this paper is twofold. Firstly, to analyse the international behaviour of academic spin-offs to explore the internationalisation patterns followed by these companies, considering precocity, scale, and scope as the key dimensions of the internationalisation process. The second objective is to discern whether academic spin-offs that follow different patterns present distinctive characteristics. To test the hypotheses, a cluster analysis, a series of ANOVA analyses of variance and post hoc tests were performed on a sample of 161 Spanish academic spin-offs. Results show that 49% of these firms do not internationalise and that three patterns of internationalisation exist in academic spin-offs: true born global, sporadic born global, and born again global. On the other hand, the results also reveal distinctive antecedent factors among the different internationalisation patterns. Thus, international industrial networks and management team functional heterogeneity are more relevant in academic spin-offs that follow the true born global and the born again global patterns, while global technological competence is significant for all three internationalisation patterns, and international academic networks present minor importance for the internationalisation process developed by academic spin-offs.
Nezha-D: Dynamic Characteristics and Design of a Ducted HAUV
Authors: Xie Hongfei , Jin Yufei , Bi Yuanbo , Zeng Zheng 
Published: January 2025

Abstract
Hybrid aerial underwater vehicles (HAUVs) can operate in water and air and are qualified for complex missions on the air-water interfaces. The unique working conditions put forward higher requirements for the propulsion systems of the vehicles. Present HAUVs’ propulsion systems mostly use propellers, but normal aerial propellers work inefficiently underwater, constraining the underwater applications of HAUVs. Besides, in-depth research of the thrusters, especially during the water-crossing process, is limited. These are two major factors that affect the further development of HAUVs. This paper aims to evaluate the feasibility of the ducted fan propulsion system and design a ducted HAUV with better underwater working capacity. Ducted fans have promising applications on HAUVs for higher underwater efficiency, but the outer ducts can lead to significant thrust loss during the water-crossing process. A novel experimental platform is firstly developed with the capability of collecting dynamic data of the thruster during water- air transition. The new water-crossing strategy and overall design of the HAUV are proposed based on the test results. The ducted HAUV is supposed to accelerate underwater and rush out with a certain speed to overcome thrust loss. A centroid adjustment mechanism has also been designed to realize the underwater motion switch for better efficiency. A prototype named “Nezha-D” is fabricated, and outfield tests are conducted to verify the feasibility of the new design.

Abstract
We consider the reconciliation problem, in which the task is to find a mapping of a gene tree into a species tree. In this paper we present a method, where for a given choice of parameters, we are able to compute the likelihood for alternative reconciliations. We describe a Markovian binary tree (MBT) model for the evolution of species trees, a quasi-birth-and-death (QBD) model for the evolution of gene trees, and provide a recursive algorithm to compute the likelihood of a given reconciliation between a species tree and a gene tree. We derive our results using the theory of matrix-analytic methods, prove them using rigorous mathematics together with decomposition of sample path arguments, and describe algorithms for the computation of a range of useful metrics. We illustrate the theory with examples and provide the physical interpretations of the discussed quantities, with a focus on the practical applications of the theory to incomplete data.
Teachers’ goals for teaching writing to economically disadvantaged students: relations with beliefs and writing instruction
Authors: Ng Clarence , Graham Steve 
Published: January 2025

Abstract
This study examines how writing is taught to students from low socioeconomic status (LSES) backgrounds, considering the issue of writing underperformance of these students. A total of 241 Australian teachers from Grades 4 to 6 completed a survey questionnaire. Using an achievement goal perspective, structural equation analyses revealed the link between teachers’ beliefs about students’ cognitive attributes and the suitability of basic writing instruction, with their teaching goals and the frequency of teaching writing skills. Cluster analyses identified three distinct groups of teachers with differing goal profiles, beliefs, and writing instructional practices. The findings highlight the importance of mastery goals in teaching writing to LSES students.
Normative anti-normativity: when Dugin reads queer theory
Authors: Wilson Trevor 
Published: January 2025

Abstract
In line with a recent rise in anti-LGBTQ discourse within conservative Russian politics, Aleksandr Dugin has increasingly critiqued “postmodern” theories that allegedly underpin social diversity (sexual, gender, racial, etc.) within the West: queer theory, post-structuralism, and other theoretical accounts of identity and alterity. In Dugin’s argument for a political philosophy of Eurasianism, the Western endorsement of multiculturalism and pluralism is indicative of individualism and “Atlanticist” liberalism, therefore at odds with the traditional, nationalist collectivism of Eurasia. In this light, queer theory is a Western imposition whose philosophical premises directly contradict native, Russian traditions. Dugin’s attack on queer theory, however, mark a departure from the philosopher’s earlier career within the National Bolshevik movement. Throughout the nineties, Dugin was relatively sympathetic with the nascent LGBT movement in Russia: specifically within the political and philosophical circles of National Bolshevism, in which such figures as Eduard Limonov and Slava Mogutin coalesced with fascists and communists around a broad critique of Western capitalism and openly embraced homoeroticism and countercultural, queer dissidence. Dugin’s links to the LGBT movement are even relatively mainstream: his first wife, Evgeniia Debrianskaia, was a prominent gay activist, and both Debrianskaia and Dugin for a time viewed the Eurasianism’s goals as aligned with that of LGBT activism in Russia. This article examines the development of Dugin’s political philosophy in the context of his reading of queer theory. It first discusses the link in historical terms, in the connections between Dugin’s early post-Soviet career and post-Soviet Russian gay activism. The article then focuses on Dugin’s philosophy of “multipolarity,” as a form of resistance to universalist, American hegemony, in order to illustrate how Dugin’s Eurasianist account of political “anti-normativity” both aligns and contradicts with his reading of queer theory. The article concludes with comments on the globalization of queer theory, cultural imperialism, and its relationship to Dugin’s geopolitics.
Shallow groundwater near a deep-well CO2 storage site—15 years of stable water quality for agricultural use
Authors: Zhou Zibo , Zhang Kexin , Callahan Damien L. , Timms Wendy 
Published: January 2025

Abstract
Injecting CO2 into deep geological formations can be an effective carbon removal and storage technology to mitigate global climate change. Interaction of injected CO2 with rock formations changes pH and hydrochemistry within the deep injection zone (> 800 m depth). However, cap rocks and multiple tight aquitards typically act as barriers to protect the shallow aquifer from changes in the injection zone. Monitoring and evaluation of shallow groundwater quality are essential to verify that carbon capture storage projects (CCS) do not impact the near-surface environment. This study investigated shallow groundwater quality using long-term data (2006–2023) from a regular monitoring program at the Otway International Test Centre (OITC) in Victoria, Australia. It was found that shallow groundwater quality was stable over at least 15 years, during which time three phases of CO2 injection into a deep storage zone occurred. The results highlighted groundwater quality complied with guidelines of Food and Agriculture Organization (FAO) and Australian water quality guidelines. Minor and localised changes observed in salinity or pH in shallow monitoring piezometers were caused by natural processes. Moreover, a wide range of groundwater quality indicators were evaluated. The results demonstrated that the groundwater quality of shallow aquifers (< 80 m) at OITC is suitable for agriculture. The study provides assurance and confidence to stakeholders that the quality of the near-surface environment has not been impacted by CO2 injection into confined formations and no pollution has been detected. Although numerous CCS sites around the world are subject to monitoring, no evidence of changes in shallow groundwater quality has been reported that could be traced to CO2 injection in confined formations at > 800 m depth.

Published: January 2025

Abstract

Background
Traumatic brain injury (TBI) in children, including concussion, is one of the major causes of emergency department (ED) registration and a significant burden on the health system.

Objectives
The primary goal of this study was to evaluate the outcomes of a telemedicine strategy for remotely monitoring the children with traumatic brain concussions, focusing on their neurological symptoms and signs. The secondary goal was to explore socioeconomic and educational differences among the participating families.

Methods
This study was conducted in a prospective and observational fashion. It included children aged between 6 and 18 years who presented in the ED with head trauma and were subsequently diagnosed with a brain concussion. Enrolled patients split into telemedicine-only and telemedicine + readmission groups according to their concussion symptoms during video-call visits.

Results
We recruited 29 children and performed 75 telehealth visits. Four children were called for readmission, and they comprised the telemedicine + readmission group. The telemedicine-only group included 25 children whose follow-ups were completed remotely. The median PECARN score was 1 (IQR = 0.75), and the most common reason for head trauma was simple falls from the same level (n = 18, 62%); 22 (76%) children were suffering from headaches; 55% of the families were in very low-income status. During the video-call visit sessions, three children stated worse headaches, and one child’s parents reported consistent sleepiness.

Conclusion
This study demonstrates the potential effectiveness of telemedicine in monitoring children with concussions, especially in regions with diverse socioeconomic backgrounds and overcrowded metropolitan hospitals.

Abstract
We introduce and study a family of non-conformal and non-uniformly contracting iterated function systems. We refer to the attractors of such systems as parabolic carpets. Roughly speaking they may be thought of as nonlinear analogues of self-affine carpets which are allowed to have parabolic fixed points. We compute the L

-spectrum of a class of weak Gibbs measures supported on parabolic carpets as well as the box dimensions of the carpet itself.
Data-ing process with image-based data: variable identification and generation
Authors: Kazak Sibel 
Published: January 2025

Abstract
Using photographs as data, which involves making observations from images and organizing them into variables to answer statistically investigative questions, is recommended for K–12 level statistics education. Research is needed to support pre-service mathematics teachers’ experiences with exploring such image-based data. With this task-based interview study, the goal was to shed light on (1) the pre-service mathematics teachers’ data-ing actions during identifying and generating variables in relation to data familiarization, question posing, and data organization components and (2) how pre-service mathematics teachers identified and generated variables in the process of data-ing. Data from video recordings, transcripts of the interview sessions for each pair, and their work with photos on the shared online document, that is, groupings and questions posed, were analyzed using a progressive focusing approach. The results showed that the data-ing actions during identifying and generating variables with data familiarization, question posing, and data organization included observing, interpreting, conjecturing, inferring, comparing, grouping, ordering, questioning/question posing, relating variables, categorizing variables, and measuring variables. The pairs used various combinations of multiple actions while data-ing. There were two types of variable identification: (1) observational variables based on visual judgment or metadata and (2) inferential variables based on personal interpretation. The latter type presented a tension between the variable defined and how to measure it objectively, as well as challenges in writing clearly defined variables when posing questions.
Effective Repeated Production of γ-glutamylcysteine, Essential For Intracellular Glutathione Production, Using Cellulose-immobilized Phytochelatin Synthase-like Enzyme NsPCS

Published: January 2025

Abstract
γ-Glutamylcysteine (γ-EC) can increase intracellular glutathione (GSH) levels, which may prevent and alleviate age-related disorders and chronic diseases caused by oxidative damage. However, the commercial availability of γ-EC remains limited owing to its complex chemical synthesis from glutamate and cysteine. In this study, we have developed the method of the effective conversion of GSH to γ-EC to achieve the optimal reaction conditions for repeated batch production and potential application in industrial γ-EC production using the phytochelatin synthase-like enzyme NsPCS. For repeated batch conversion reactions, the optimal temperature was determined at 25 °C, where γ-EC showed good stability compared with that at 37 °C, leading to higher overall productivity. Cellulose sponges and microcrystalline cellulose (MCC) showed superior mechanical strength as immobilization carriers and greater stability and productivity than other materials. The total amounts of γ-EC obtained by NsPCS immobilized on the cellulose sponge and MCC were 305 mg and 291 mg, respectively, in a 5 mL reaction over five repeated batch reactions. These simple production processes are easily reproduced, and their high volumetric efficiency is promising for the industrial production of stable and low-cost γ-EC.
Three paradigms of inquiry into self-regulated learning (SRL): a critical analysis and ways to transformative and integrated practices
Authors: Dan Qingyao , Yin Hongbiao , Bai Barry 
Published: January 2025

Abstract
This paper aims to review and conceptualize how researchers with different human interests understand and approach self-regulated learning (SRL) for their specific purposes. In this narrative literature review, three paradigms of inquiry into SRL guided by Habermas's three human interests (i.e., technical interests, practical interests, and critical/emancipatory interests) are presented in an interpretive way. It was found that, with various human interests, researchers' definitions of SRL, the understandings of the roles of students and social contexts, inquiry interests and intentions, and the methodologies adopted vary. By incorporating Habermas's three human interests into SRL inquiries, this article offers a comprehensive and critical narrative review of the three paradigms in SRL. Discussions about the extension of the established paradigm and the alternative approaches to SRL, emancipatory transformative practices, and the strengths and weaknesses of the three paradigms and their integrated application provide insights and implications for SRL research and practices.
Analyzing Shock Transmission and Spillover Effect in the Day-Ahead and Intraday Markets: Key Implications for Price Forecasting
Authors: Oprea Simona Vasilica , Bâra Adela 
Published: January 2025

Abstract
The increasing capacity in renewables (RES) and batteries in the Romanian power system stirred discussions on increasing interdependency between day-ahead market (DAM) and intraday continuous (IDC) market. In this paper, we analyze hourly market-cleared prices and selling and buying quantities in the DAM and IDC over 3 months (4th of June to 11th of September 2024) to verify the connectedness between prices of the two markets, possible shock transmission and spillover effects. We employ generalized autoregressive conditional heteroskedasticity (GARCH) models to examine volatilities. The Diebold–Yilmaz spillover index is 95.69%, demonstrating an extremely high degree of volatility interdependence. This suggests that nearly all volatility in both markets is driven by cross-market shocks. Price shocks in the DAM initially raise IDC prices by 0.3 units, with this effect fading after 8 to 10 periods. Conversely, IDC shocks similarly raise DAM prices by 0.3 units, but both effects are temporary, indicating a short-term dynamic link between the two markets. Moreover, numerical results from the BEKK-GARCH model highlight significant volatility spillovers between Price_DAM and Price_IDC, with stronger cross-market volatility effects and evidence of interdependence, particularly from Price_IDC to Price_DAM. The findings suggest implications for market players to create bidding strategies and decision-makers to mitigate price volatility connectedness in DAM and IDC. Furthermore, our findings underscore the critical role of knowledge creation and diffusion in understanding the interconnected dynamics of electricity markets. By leveraging advanced econometric tools and spillover analysis, our research contributes to the body of knowledge essential for innovation in market strategies and decision-making processes.
Assessing children’s capacity for procedural flexibility with mental addition
Authors: Hopkins Sarah , Russo James , Downton Ann 
Published: January 2025

Abstract
Children’s number-based procedures for mental computation have been widely studied but few studies have focused on children’s flexibility with mental computation procedures. In this study, we investigated children’s capacity for procedural flexibility with mental addition by developing and testing a novel assessment that required them to recognize an efficient strategy used by another (fictitious) child. Testing was conducted in eight metropolitan primary schools in Australia and involved administering the assessment to children in Years 3 and 4 (N = 853). The final version of the assessment comprised 23 items and produced data that were closely aligned to the Rasch model, reflected a unidimensional construct and showed good precision and excellent reliability. Findings from item analyses confirmed predictions about the problem features that evoke thinking about particular strategies and the comparative difficulty of strategy types. These findings contribute insights into how procedural flexibility may be operationalised, making it possible to compare instructional approaches for promoting procedural flexibility on a large scale.

Abstract
Bumblebees are ubiquitous, cold-adapted, primitively eusocial bees and important pollinators for crops and vegetation. However, many species are declining worldwide due to multiple factors, including human-induced habitat loss, agricultural chemicals, global warming, and climate change. In particular, future climate scenarios predict a shift in the spatial distribution of bumblebees under global warming, with some species declining and others potentially expanding. Here, we report a de novo genome assembly and annotation for Bombus lapidarius and Bombus niveatus to decipher species-specific potential genomic capacity against such environmental stressors. With harboring more than 23,000 protein-coding genes, the assembled genomes of B. lapidarius and B. niveatus are 244.44 Mb (scaffold N50 of 9.45 Mb) and 259.84 Mb (scaffold N50 of 10.94 Mb), respectively, which exhibit similar trends in terms of genome size and composition with other bumblebees. Gene family analysis reveals differences in species-specific expanded gene families. B. lapidarius exhibits expanded genes related to pre/postsynaptic organization, while B. niveatus shows a distinct expansion in gene families regulating cellular growth, aging, and responses to abiotic and biotic stressors, such as those containing SCAN domains, WD-repeats, and Ras-related proteins. Our genome-wide screens revealed positive selection on environmental stress-responsive genes such as dip2, yme1l, and spg7 in B. lapidarius, whereas positive selection signatures were found in genes such as myd88, mybbp1A, and rhau, which are involved in environmental stress resistance for B. niveatus. These high-quality genome assemblies and comparative genome analysis unveil potential drivers that underlie genome evolution in bumblebees, offering valuable insights into environmental adaptation and conservation efforts.
