Exploring Teachers’ Competences to Integrate Augmented Reality in Education: Results from an International Study
Authors: Nikou Stavros A. , Perifanou Maria , Economides Anastasios A. 
Published: November 2024

AbstractAugmented Reality (AR) can enhance learning experiences offering many benefits to students. However, its integration in educational practice is rather limited due to several obstacles. One of these obstacles is the absence of AR digital competencies among instructors. Limited research exists about teachers’competence areas in integrating AR in teaching and learning. The current study utilizes the validated Teachers’ AR Competences (TARC) framework to investigate teachers’ self-perceived competences in creating, using, and managing AR resources. Furthermore, it investigates educators’ attitudes towards integrating AR in education. An online survey received responses from 150 educators worldwide. Quantitative results indicated that while teachers have positive attitudes towards educational AR, they do not feel confident in creating, using, or managing AR resources and experiences. All TARC subscales found to be significantly correlated to attitudes towards AR. No significant differences were found across all competence areas in regard to gender, age, and teaching level. However, statistically significant differences were found across all competence areas with respect to the teaching subject, general digital skills level, and previous class use of AR. Among the main practice and policy implications discussed, we suggest the need for training teachers in instructional design that deploys AR experiences.

AbstractThis prospective, observational study evaluated Hyperspectral Imaging (HSI) to assess the effects of cardiac surgery and cardiopulmonary bypass (CPB) on microcirculation. 40 Patients with severe aortic stenosis were enrolled. 20 patients underwent transapical/transaxillary/transaortic aortic valve replacement (TAVR), 20 underwent an open surgical approach with CPB (SAVR). HSI was used to determine tissue oxygenation (StO2 and NIR), hemoglobin (THI) and water content (TWI) at the palm before/after surgery (T1/T2), and on the third postoperative day (T3). TAVR patients showed no significant changes of microcirculatory parameters during surgery. TWI significantly increased until T3. SAVR patients showed an increase of TWI and a decrease of THI, while StO2 and NIR remained unchanged at T2. In SAVR patients, StO2 and NIR correlated negatively with the duration of CPB and StO2 correlated with intraoperative urine output at T2. HSI was able to detect microcirculatory changes during cardiac surgery. CPB duration seemed to affect tissue oxygenation. Clinical trial registration: (German Clinical Trial Register): DRKS00024765.

AbstractMembranous nephropathy (MN) is a common cause of adult-onset nephrotic syndrome. It is also known as a minor but established renal manifestation of Immunoglobulin G4-related disease (IgG4-RD). Previous reports suggest that MN can also be an initial manifestation of IgG4-RD, all of which are phospholipase A2 receptor (PLA2R)-negative MN. We describe a case of PLA2R-positive MN that subsequently developed other manifestations of IgG4-RD. A 60-year-old male with nephrotic syndrome was diagnosed as primary MN with positive staining for PLA2R on the initial renal biopsy, which remained in partial remission with supportive therapy using angiotensin II receptor blocker (ARB) without steroid. About 1 year later, a renal mass was detected during an annual checkup, and contrast-enhanced computed tomography revealed low-density masses in bilateral kidneys and the head of the pancreas. The findings of endoscopic biopsy of the pancreatic mass were consistent with autoimmune pancreatitis (AIP) and the second renal biopsy showed the findings of MN with tubulointerstitial nephritis, both of which led to a diagnosis of IgG4-RD. The second renal biopsy also showed positive PLA2R. The patient received oral glucocorticoid therapy for IgG4-RD, which improved IgG4-related AIP and renal masses and also resulted in complete remission of MN. To our knowledge, this is the first reported case of PLA2R-positive MN with subsequent development of IgG4-RD. It is sometimes difficult to determine whether PLA2R-positive MN occurring with IgG4-RD is primary MN or secondary MN associated with IgG4-RD. The possibility of developing IgG4-RD should be considered even when preceding MN is PLA2R-positive, suggesting of primary MN.

AbstractFor luminescent materials, negative thermal quenching (NTQ), characterized by an increase in the luminescent intensity with temperature, has a large potential in lighting and display technologies. However, leveraging NTQ in metal halide perovskites is challenging, and the mechanism is not well understood. Herein, by utilizing low-temperature photoluminescence, persistent luminescence and thermoluminescence, the origins of NTQ in CsPbBr3 microspheres are systematically studied, which pertain to the liberation of carriers from shallow trap states. Experimental and theoretical investigations reveal that the energy of these shallow defect states is approximately 0.135 eV beneath the conduction band. A rapid thermal treatment increases the density of these shallow traps and amplifies the NTQ effect, resulting in an enhancement of room-temperature photoluminescence by more than 60% compared to that at 150 K. The process also reduces the threshold for amplified spontaneous emission to about 45 W/cm2. Our findings not only provide a deeper understanding of the NTQ phenomenon in CsPbBr3 microspheres but also open new avenues for enhancing the performance of perovskite optoelectronic devices through energy state regulation.
Integral points on a del Pezzo surface over imaginary quadratic fields
Authors: Ortmann Judith 
Published: November 2024

AbstractChambert-Loir and Tschinkel constructed a framework for a geometric interpretation of the density of integral points on certain varieties, which was refined by Wilsch. By using harmonic analysis and the circle method, it was proved for some partial equivariant compactifications of vector groups over arbitrary number fields and high-dimensional complete intersections over $${\mathbb {Q}}$$
Q
. Further, there are some examples of using the torsor method for singular del Pezzo surfaces over $${\mathbb {Q}}$$
Q
. In this paper, we generalise the torsor method for integral points from $${\mathbb {Q}}$$
Q
to imaginary quadratic number fields. As a first representative example, we characterise integral points of bounded log-anticanonical height on a quartic del Pezzo surface of singularity type $${\textbf{A}}_3$$

over imaginary quadratic fields with respect to its singularity and its lines. Furthermore, we count these integral points of bounded height by using universal torsors and interpret the count geometrically to prove an analogue of Manin’s conjecture for the set of integral points with respect to the singularity and to a line. Our results coincide with the predicted framework.
Pankreaszysten – Was gibt es Neues?
Authors: Rainer Florian 
Published: November 2024

ZusammenfassungDie neuen Kyoto-Leitlinien bieten eine evidenzbasierte Grundlage für die Behandlung von neoplastischen Pankreaszysten, insbesondere von intraduktal papillär muzinösen Neoplasien. Im Vergleich zu den vorhergehenden Tokyo-Leitlinien wurde die Wertigkeit der Endosonographie und der Punktion aufgewertet, die Indikationsstellung zur chirurgischen Sanierung wurde liberaler formuliert und nähert sich somit den europäischen Leitlinien an. Auch beim Vorliegen mehrerer „worrisome features“ kann dem Patienten nach individueller Risikoabschätzung eine chirurgische Sanierung angeboten werden. Zusammenfassend ist zu sagen, dass weiterhin ein großer Teil der Empfehlungen auf Evidenz mit niedriger Qualität basiert und deshalb die Diskussion der Befunde mit dem/der Patient:in und die gemeinsame Entscheidungsfindung weiterhin einen großen Stellenwert einnimmt. Trotz der beschriebenen Fortschritte gestaltet sich die Betreuung von Patient:innen mit Pankreaszysten weiterhin schwierig. Es bleibt zu hoffen, dass wir in den nächsten Jahren bessere diagnostische und prognostische Werkzeuge entwickeln, die es ermöglichen, das Risiko von neoplastischen Pankreaszysten besser einzuschätzen.
Digitally supported coaching and its application to developing self-organizing teams
Authors: Spielhofer Thomas , Motschnig Renate 
Published: November 2024

Abstract
Digital communication has become mainstream in professional as well as in educational collaboration. While it reduces the richness of non-verbal interaction, it also opened up novel, accessible, and low-cost opportunities for professional as well as personal development. This paper presents the findings of applying the framework called digitally supported coaching (DSC) to a self-organized team that partly collaborates via online video conferences. The DSC features a software tool that analyzes and visualizes communication data of several meetings and a team coaching process to use these visualizations for team development. This allows teams to discern helpful and less helpful patterns in their communication and to learn from that. While DSC has already been evaluated in multiple case studies in different contexts, this study explores the use of DSC for a self-organized team for the first time. Applying a mixed method approach, the team communication was analyzed from the subjective perspectives of the team members as well as based on the quantitative data of the meetings and the social network analysis (SNA) derived from it. Compared to hierarchical teams, the results show a much higher variety in team centralities and significant differences in the way meetings were led. Learnings by the team in this case included insights regarding their roleplay, the way they moderated meetings, and their development towards more constructive communication over time. The case indicates the potentials of DCS for self-organized teams particularly regarding their flexibility in taking on roles, tasks, and reflective practice.
Industrial Policy for the United States
Authors: Fasteau Marc , Fletcher Ian 
Published: November 2024

The U.S. is losing the competition for good jobs and high-value industries because most of Washington believes trade should be free, the dollar should float, and that innovation comes exclusively from the private sector. In this book, the authors make the bold case that these laissez-faire ideas have failed and that a robust industrial policy is the only way for America to remain prosperous and secure. Trump and Biden have enacted some of its elements, but it needs to be made systematic and comprehensive, including tariffs to protect key industries, a competitive exchange rate, and federal support for commercialization—not just invention—of new technologies. Timely, meticulously researched, and bipartisan, this impressive analysis replaces misunderstandings about industrial policy with lucid explanations of its underlying economic theory, the tools that implement it, and its successes (and failures) in America and abroad. It examines key industries of the past and future – steel, automobiles, television, semiconductors, space, aviation, robotics, and nanotechnology. It concludes with a realistic, actionable policy roadmap. A work of rigor and ambition, Industrial Policy for the United States is essential reading.
Why Office of Management and Budget’s (OMB) Social Welfare Function Is Not Society’s Social Welfare Function
Authors: Viscusi W. Kip 
Published: November 2024

AbstractIn 2023, the U.S. Office of Management and Budget (OMB) issued guidance documents that specified new procedures for assessing prospective government regulations (Circular A-4) and economic policies more generally (Circular A-94). These revisions to long-standing guidance were not minor updates but shifted policy analyses from an efficiency-oriented perspective to a redistributive approach. OMB broadened the guidelines for reporting distributional consequences of policies and also specified how policy impacts on different income groups should be weighted. The weights assume that the social welfare function is governed by the sum of identical individual utility functions, each of which exhibits a substantial rate of diminishing marginal utility of income. The resulting weights provide a premium for households below the median-income level and a considerable penalty for those at higher-income levels. Application of the weights to property losses creates potentially substantial inefficiencies. If based on current empirical evidence on the income elasticity of the value of a statistical life rather than assuming that there is a complete offset of the weights, application of the weights to mortality risk valuation would generate inequities in protection.
Labour market segmentation, self-employment, and Hukou reform
Authors: Huang Chunyang , Ke Wenxiu 
Published: November 2024

AbstractThis study aims to examine the impact of the Hukou system, a labour mobility-restricting institution, on the decision to engage in non-agricultural self-employment in China, reflecting the dynamic process of labour transition from contractual work to self-employment within the country’s evolving labour market. By using the China Family Panel Studies (CFPS) dataset, the results show that urban migrants, who own rural Hukou but migrate to large cities, are more likely to turn to self-employment than local citizens conditional on individual characteristics. Taking advantage of the 2014 Hukou reform, we provide supporting evidence that Hukou discrimination is a key factor in explaining the higher self-employment rate among representative urban migrants. Further heterogeneous analysis suggests that low-income migrants experience greater constraints imposed by the Hukou system, while high-income level migrants are more likely to turn to self-employment voluntarily.

-torsion and has order at most

$18$

. Under the additional assumption that A is of

Leader’s feelings of violation and high LMX relationships: A multilevel approach to examine a contextual boundary condition in LMX

Published: November 2024

Abstract
Leader–member exchange (LMX), a well-researched leadership theory that focuses on the dyadic relationships between leaders and subordinates, is associated with positive subordinates’ outcomes. However, the contexts outside the LMX dyadic relationship might influence those favorable outcomes. In this study, we investigate the cross-level moderating effect of leader’s feelings of violation, as a contextual boundary, on LMX outcomes. Based on social exchange theory, crossover model, and the psychological contract literature, we discuss how the relationship between a subordinate’s perceived LMX and favorable subordinate attitudes and behaviors, such as performance, task-focused citizenship behaviors, and organizational commitment, is reduced when the leader experiences feelings of violation toward the organization. Using a three-wave time-lagged multilevel design with a sample of 226 subordinates and 39 leaders, we find that leader’s feelings of violation mitigate the positive association of perceived LMX on citizenship behavior and commitment but have no effect on performance. Research and practical implications are discussed.
Advocacy versus depart: How perceived organizational support influences employee well-being and shapes their intentions
Authors: Viot Catherine , Benraiss-Noailles Laila 
Published: November 2024

Abstract
This study investigates the influence of perceived organizational support (POS) on employees’ intentions to recommend their employer or leave the organization. Based on social exchange theory, it explores how POS affects employee well-being and shapes behaviors such as loyalty and advocacy. An online survey gathered data from 604 French employees across various sectors, analyzing variables like POS, positive and negative well-being, and intentions to leave or recommend the employer. Structural equation modeling was used to examine the relationships among these variables and to test the mediating role of well-being. Results show that POS positively influences employee well-being. High POS is associated with improved positive well-being, which decreases the intention to leave and increases the intention to recommend. Similarly, reduced negative well-being linked to high POS lowers the desire to leave and lessens negative effects on recommendation intentions. The study confirms the mediating role of well-being between POS and employee intentions. The study provides new insights into the impact of POS on employee intentions by highlighting the pathways of positive and negative well-being. For human resource practices, strengthening POS is essential to boost employee retention and encourage positive behaviors, thereby enhancing the organization’s reputation and attractiveness.
Querying Public Scholarship: An Unfinished List of Questions toward More Meaningful University–Community Partnerships
Authors: Kornstein Harris , Barrios Jacqueline Jean 
Published: November 2024

Abstract
How do we do public scholarship? It might seem like a simple question, but as anyone who has attempted to experiment with academic norms—let alone work collaboratively in and through institutional regulations, cultural expectations, and diverse personalities—is well aware, things get complicated quickly. As scholars, practitioners, and educators in the public humanities, the authors offer a set of sticky and thorny questions that are both theoretically minded and practice oriented, as possibilities to consider throughout the process of working on public projects or with community partners. Questions are grouped thematically—Framing, Planning, Partnerships, Institutions, Tools, Outputs and Forms, Documentation, Evaluation and Reflection—though are not meant to be exhaustive or prescriptive. In so doing, the essay insists that public scholarship not be codified into a clearly-defined discipline, but rather acknowledged as both an always already present practice for many scholars and in a constant state of emergence as a field. To that end, the authors also invite direct engagement with these questions, both inside and outside of the space of the text, encouraging readers to generate and share their own questions as well.
On (And Off) the Waterfront: The International Longshore and Warehouse Union and Its Place in Labor History
Authors: Meyris Andreas 
Published: November 2024

Abstract
Labor historians, particularly in the United States, have given unique attention to the International Longshore and Warehouse Union (ILWU). Emerging out of a series of tumultuous strikes on the West Coast during the early Depression years, the ILWU won trend-setting employment contracts, survived Second Red Scare-era persecution despite keeping avowedly leftwing leadership, and maintained its presence on the docks even after containerization dramatically reshaped the longshore industry. This review examines multiple recent works on the ILWU, noting new interventions—both in ILWU history and labor history, more broadly. All three reviewed works offer invaluable insight for how contemporary unions can adapt to technological changes in the workplace, foster internal democracy, and build labor power while fighting for social justice. The review concludes by offering potential avenues for further scholarly research, particularly on the nature of leftwing unionism and labor-generated alternatives to deindustrialization and workforce displacement.
Unequal Power Relations at the Center of Social Vulnerability to Climate Change: Empirical Insights from Coastal Bangladesh
Authors: Ahmed Saleh 
Published: November 2024

ABSTRACTClimate change is a global phenomenon affecting millions of people. Low-income people and communities are particularly at risk because of limited capacities to cope with climate-related stresses. Differential access to social and economic resources determines the level of adaptive potential; thus, the variations in social vulnerability to climate change. This article explores how unequal power relations influence the level of vulnerability in rural agrarian Bangladesh. Using data from the coastal region, it specifically discusses ethnicity, religion, gender, and farm size as the sources and manifestations of power relations in Bangladeshi rural society. I argue that the deeply rooted institutions of power in the country shape access to important resources that might increase adaptive capacity and thus resilience in the context of rapid climate change.
