AbstractAlthough achievement situations trigger multiple emotions and learners experience both negative and positive emotions simultaneously, procrastination research typically examines isolated relationships between specific emotions and procrastination. The potential interplay of negative and positive emotions regarding procrastination is often overlooked, although this perspective can shed light on their dynamic relationships. Moreover, past studies primarily address the behavioral aspect of procrastination (delay) while overlooking its emotional facet (subjective discomfort), albeit this differentiation could enhance understanding of procrastination and its correlates. The present study explores the understudied interplay of the two most frequently experienced negative (anxiety) and positive (hope) exam-related emotions regarding students’ procrastination tendencies with differentiated behavioral and emotional dimensions. The study analyzes cross-sectional data from two independent studies (Nstudy1 = 266, Nstudy2 = 468) conducted in Germany among university students. Latent profile analyses (LPA) reveal three similar profiles across both studies—High Anxiety–Low Hope, Low Anxiety–High Hope and Moderate Anxiety–Moderate Hope— and two study-specific profiles namely, Low Anxiety–Moderate Hope (Study 1) and High Anxiety–Moderate Hope (Study 2). Females compared to males are more likely to belong to the anxiety-dominated profiles. Overall, students in anxiety-dominated profiles report higher scores whereas students in hope-dominated profiles report lower scores on both behavioral and emotional dimensions of academic procrastination. This study advances an integrated approach that incorporates the combined effects of both negative and positive emotions concerning procrastination. Findings further inform research efforts towards identifying risk and protective emotional factors to develop tailored intervention against academic procrastination.

Abstract
Purpose
Powder feeding is a vital unit operation in the continuous manufacturing of pharmaceutical products. Loss-in-weight twin-screw feeders are commonly used in continuous manufacturing lines. The feeding performance, i.e., the accuracy and consistency of feeding, influences the content uniformity of the final drug product. In this study, a redesigned hopper for K-Tron KT20 twin-screw feeder was designed, implemented, and investigated to improve feeding performance. The basic idea was to design the hopper in such a way that the stresses on top of the screw entrance are independent of the fill level.

Methods
Our study compared the novel system to that of the original cylindrical hopper. The effect of the redesigned hopper on the start-up, the process’ sensitivity to refill level, and the refill portion size were studied. A free-flowing, barely compressible powder and a compressible blend were used in this study to evaluate the feeding performance and the refill effects.

Results
When using compressible powders, the results showed a larger process window for refilling in the redesigned hopper and a lower refill-level sensitivity compared to the original hopper.

Conclusion
The homogenization of stresses in the redesigned hopper allowed operating at lower refill levels, and variability, especially due to refilling, was reduced. This study demonstrates novel design approaches for successfully implementing hard-to-feed materials in continuous manufacturing.

AbstractColorectal cancer (CRC) awareness and screening rates are still low in African Americans (AAs), especially for those who do not have regular access to health care. We established a multi-sector community partnership between academia, health system, cancer advocacy, and local county treasurer’s office (CTO), to test a pilot CRC screening intervention using a tailored educational brochure and fecal immunochemical test (FIT). Participants were recruited at a local CTO in an urban midwestern region. Once eligible, participants were assigned to 2-by-2 intervention arms by educational strategy (brochure vs. no brochure) and FIT provision strategy (direct provision by onsite staff vs. indirect provision via phone/online request). We compared the effect of different strategies on FIT return rates. Of 1500 individuals approached, 212 were eligible for the study. The final sample consisted of 209 participants who were predominantly men (57%) and AAs (85%). No differences were found in the return rates by educational brochure (24% [brochure] vs. 23% [no brochure]; p = 0.82). In regard to FIT provision strategy, direct FIT provision yielded higher return rates than indirect provision (31% vs. 15%; p = 0.01). When the four groups were compared, direct provision with education brochure yielded the highest return rates (33.9%), followed by direct provision only (27.5%), indirect provision only (18%), and indirect provision with a brochure (12.2%). For community-based CRC screening intervention using stool-based test, the direct provision of FIT kits with educational brochure outperforms the other three strategies.

AbstractSand production causes many problems in the petroleum industry. The sand production is predicted to control it in the early stages. Therefore, accurate prediction of sand production has been considered substantial in achieving successful sand control. Critical total drawdown (CTD) can indicate the sand production. The main drawback of the previous studies in predicting CTD is their lack of accuracy. Thus, this study aims to develop an accurate CTD estimation prediction model employing a trend analysis and adaptive neuro-fuzzy inference system (ANFIS). The method is chosen because of its higher performance; the model is built based on 23 published datasets from the Adriatic Sea. The developed ANFIS model is evaluated using various methods, namely, trend analyses. Trend analyses are conducted to show the effects of the features on the CTD to present the physical behavior. The model’s performance was also evaluated using statistical error analyses. In addition, the ANFIS and previously published models were assessed. The trend analyses show the correct relationship between all features and the CTD. In addition, the trend analyses for the previous models are discussed. The results show that the proposed ANFIS method outperforms published methods with an R of 0.9984 and an absolute average percentage relative error (AAPRE) of 4.293%.
Hybrid Nanoparticle-Enhanced Fluid Flow and Heat Transfer Behaviors in a Parabolic Cavity with a Heat Source
Authors: Mohebbi Rasul , Ma Yuan 
Published: September 2024

AbstractNatural convection of nanofluids holds considerable importance in both scientific research and engineering applications due to their exceptional heat transfer capabilities, which occur spontaneously without the need for additional energy input. In this paper, the natural convection of nanofluid inside a parabolic cavity containing a hot obstacle is studied numerically. The shape of the hot obstacle is selected as either circular or elliptical. Additionally, the effects of the Rayleigh number, nanoparticle volume fraction, and the position of the heat source are investigated. The computational fluid dynamics model was computed using COMSOL Multiphysics. It is observed that the average Nusselt number tends to increase with both the Rayleigh number and the volume fraction of nanoparticles in the fluid. When the heat source moves from the bottom region to the top area, the heat transfer performance of the heat source increases. When Ra ≤ 105, the cases with circular heat sources exhibit better heat transfer performance than those with elliptical heat sources. However, at Ra = 106, the average Nusselt number of the elliptical heat source is higher than that of the circular one.
Bildung für nachhaltige Entwicklung als Herausforderung für die Lehrer*innenbildung. Orientierungen von Lehramtsstudierenden zu Nachhaltigkeit und nachhaltigkeitsbezogener Bildung

Published: September 2024

ZusammenfassungNachhaltigkeit und Bildung für nachhaltige Entwicklung (BNE) stellen zwei Themen dar, die in den letzten Jahren an Bedeutung im gesellschaftlichen Diskurs gewonnen haben und mittlerweile auch in den Bereichen Schule und Lehrer*innenbildung politisch forciert werden. Studien zeigen jedoch, dass angehende Lehrpersonen in Deutschland nicht systematisch auf die Umsetzung einer BNE an Schulen vorbereitet werden. Vor dem Hintergrund, dass eine solche Umsetzung sowohl Herausforderungen im Bereich der Didaktik als auch im Bereich der Schulentwicklung mit sich bringt und eine professionelle Reflexion erfordert, präsentiert der Beitrag eine explorative Studie zu der Frage, welche Orientierungen Lehramtsstudierende bei der Beschäftigung mit Nachhaltigkeit und nachhaltigkeitsbezogener Bildung leiten. Auf Basis einer Auswertung von Gruppendiskussionen mit der Dokumentarischen Methode werden hierzu zwei kontrastierende Typen erkennbar: ‚Übertragung‘ und ‚Distanzierung‘. Diese Typen gehen mit divergierenden Verständnissen von Nachhaltigkeit und unterschiedlichen Umgangsformen mit der wahrgenommenen Norm nachhaltigen Handelns und der Umsetzung einer nachhaltigkeitsbezogenen Bildung in schulischen Kontexten einher. In der Diskussion werden diese Ergebnisse zum (bislang überschaubaren) Forschungsstand relationiert und darauf aufbauend Implikationen für die Lehrer*innenbildung formuliert.

Published: September 2024

AbstractIn this study, we aim to enhance the efficiency and performance of vortex tubes by identifying the optimal material for their manufacture under specific conditions using computational fluid dynamics (CFD) simulations. We first establish a theoretical model of vortex tubes and propose a dynamic partition modeling method. Through theoretical analysis, we demonstrate the superiority of metallic materials in vortex tube applications, particularly regarding their energy distribution efficiency. We then conduct CFD simulations and experimental validations to systematically analyze the performance of vortex tubes made from different materials. The simulations utilize compressed air as the working fluid, with inlet pressures ranging from 0.1 MPa to 0.5 MPa. The materials considered include Copper, Aluminum, Steel, PVC, and Wood. Throughout the simulations, the cold mass fraction is maintained at 0.1, and the length-to-diameter ratio (L/D) of the vortex tube is set at 16. Using the standard k-ε model, steady-state numerical simulations of the gas flow inside the vortex tube are performed to analyze the variations in velocity, pressure, and temperature for different materials, pressures, and roughness conditions. Based on the physical properties of the materials, we find that metallic materials, particularly Copper, exhibit higher temperature gradients compared to non-metallic materials, with the order being Copper > Aluminum > Steel > PVC > Wood.
No Effect of Hunger on the Memory of Food Images and Prices

Published: September 2024

Abstract
Purpose
Food acquisition is an adaptive problem resolved via both physiological and psychological processes. Hunger could serve as a coordinating mechanism for these processes. When hunger increases, it may be beneficial to shift cognitive resources away from other adaptive problems and towards functions that increase the chances of acquiring food, such as memory for food information. However, there is limited research exploring the impacts of hunger on food-related memory, and the results are mixed. We conducted two studies investigating whether increased hunger levels improve memory for food images and prices – but not non-food images and prices – in image recognition and price recall tasks, respectively.

Methods
Study 1 was an online, observational study (N = 91) using self-reported hunger as a continuous measure. Study 2 was an in-person, between-subjects interventional study (N = 102) where participants were randomly allocated to a hungry or sated condition. We predicted that higher levels of hunger would improve participants’ ability to discriminate between food images they have and have not seen before and correctly recall food prices.

Results
We found no evidence of a hunger-related memory enhancement for food stimuli in either study in image recognition or price recall tasks.

Conclusion
Our findings contrast with older research but support more recent work, suggesting that the effect of hunger on food memory may be sensitive to study design and not as broadly generalisable as first thought.

From Policy to Practice: Unpacking the Politics and Realities of Environmental Education Policy in Chinese Primary Schools
Authors: Zhou Ronghui (Kevin) 
Published: September 2024

AbstractIn recent years, China’s strong commitment to the political agenda of ecological civilisation has increased the presence of environmental education (EE) in the policy arena. Using the waste classification policy as an example, this research explores the implementation of EE policy in two Chinese primary schools. Through the use of a policy enactment framework, the findings reveal that contextual factors such as school enrolment, infrastructure and external influences from the District Bureau greatly influence the schools’ policy capacity. By exploring the internal policy flow and school artefacts, it was found that although the waste classification policy was enacted similarly in the selected primary schools, the outcomes differed significantly. These variations highlight the complexities and challenges of implementing an EE policy under ecological civilisation and contribute to the understanding of the tension between localised adaptations and the nationally politicised EE policy mandates.
Conceptual foundations for a clarified meaning of the 3Rs principles in animal experimentation

Published: September 2024

AbstractRussell and Burch’s 1959 original definitions of the 3Rs (replacement, reduction and refinement) are widely used today as standards for the ethical use of non-human animals in research, although they have a number of limitations. Authors and institutions around the world have addressed some of these, coming up in certain cases with more accurate, functional, and up-to-date definitions. However, not only do there still remain limitations needing to be addressed, but some that have been addressed resulted in discrepancies, contradictions, and general confusion as to how best apply the 3Rs in practice. In order to clarify the meaning of the 3Rs and enable more optimal implementation of these principles in animal experimentation, this article provides a theoretical discussion for revised definitions of the original 3Rs via examination of some of their main limitations and inconsistencies. First, we offer up the original definitions as presented in the context of Russell and Burch’s bookThe Principles of Humane Experimental Technique.Then, we examine the main limitations and present clear specifications and requirements for such revised definitions. After presenting our revised definitions, we conclude with various implications for animal welfare within the context of experimentation.
Scenario Analysis in Karlsruhe: Exploring New Argumentative Steps of the Federal Constitutional Court
Authors: Tuzet Giovanni , Canale Damiano , Sardo Alessio 
Published: September 2024

AbstractThis Article examines scenario analysis, a disruptive argumentation technique used by the German Federal Constitutional Court (GFCC) in recent high-profile cases, such as the so-called climate protection case (Klimaschutz) and other decisions on the fundamental right to intergenerational justice (Grundrecht auf Generationengerechitgkeit). After explaining the basic argumentative steps involved in scenario analysis, for example designing scenarios, identifying stakeholders, relating scenarios to strategies, determining the main driving forces, estimating scenario probabilities, the Article sketches a normative model for rational scenario design. The normative model is used as a lens for evaluating the arguments developed by the GFCC in the climate protection case. Such evaluation also builds on game-theoretic insights and points out some weaknesses in the Court’s argument. Finally, the Article observes that, as scenario analysis is used to assess the future impact of legislative decisions, it has the effect of imposing greater constraints on legislatures.
Setting the Supreme Court’s Policy Agenda
Authors: Beim Deborah , Rader Kelly 
Published: September 2024

AbstractWe develop a new approach to understanding which legal questions the Supreme Court chooses to address. We show that the Supreme Court is more likely to resolve ideologically polarizing legal questions. This result is based on a new technique for estimating the ideology of a doctrine, which we implement using a dataset of intercircuit splits. We use this technique to identify legal issues that are ideologically polarizing and show they are more likely to be addressed by the Supreme Court than less polarizing issues. Our results demonstrate how the Supreme Court uses certiorari to advance its ideological policymaking goals.
Utrum sit una tantum vera enumeratio virtutum moralium (Whether There Is a Single Correct List of the Virtues of Character)
Authors: Chappell Sophie Grace 
Published: September 2024

AbstractVirtue ethics tells us to ‘act in accordance with the virtues’, but can often be accused, for example, in Aristotle’s Ethics, of helping itself without argument to an account of what the virtues are. This paper is, stylistically, an affectionate tribute to the Angelic Doctor, and it works with a correspondingly Thomistic background and approach. In it I argue for the view that there is at least one correct list of the virtues, and that we can itemise at least seven items in the list, namely the four cardinal and three theological virtues.
Increasing intergovernmental coordination to fight crime: evidence from Mexico
Authors: Alcocer Marco 
Published: September 2024

Abstract
Latin America is the most violent region in the world, with many countries also suffering from high levels of criminality and the presence of powerful criminal organizations. Identifying government responses that improve citizen security is imperative. Existing research argues that improving intergovernmental coordination helps the state combat criminality, but has limited its analysis to political factors that affect coordination. I study the impact of increasing intergovernmental coordination between law enforcement agencies. Using the generalized synthetic control method, original data on the staggered implementation of a police reform that increased intergovernmental police coordination and detailed data on criminal organizations and criminality in Guanajuato, Mexico, I find that the reform weakened criminal organizations and reduced violent crime, but increased violence.
Turcophile, Religious Zealot, and Rebel: The Hungarian Noble Pál Szepessy's Encounters with Grand Vizier Ahmed Köprülü (1661–76)
Authors: Michels Georg B. 
Published: September 2024

AbstractPál Szepessy (1636–1685), a Calvinist noble, dedicated his life to the goal of turning Habsburg Hungary into an Ottoman vassal state. He spent much time in the Ottoman world, met with Grand Vizier Ahmed Köprülü (r. 1661–76) on at least four occasions, and regularly visited other Ottoman dignitaries. Szepessy outlined the traumatic effects of Habsburg military occupation and Counter-Reformation on Hungarian society. He was driven by the conviction that God had chosen the Ottomans as his avengers to liberate Hungary from the yoke of the Austrian Antichrist. Szepessy won Köprülü's support for armed uprisings and a guerilla war against the Habsburgs. He also influenced the grand vizier's decision to end the Polish-Ottoman war (1672–76) and turn the Ottoman army against the Habsburg Empire. When Köprülü died in November 1676, the blueprints for Habsburg Hungary's defection to the Ottoman Empire were already in place. They were reactivated by Kara Mustafa in 1682–83. Szepessy's initiatives (and similar efforts by other Hungarians) have been ignored by scholarship; their traces remain dispersed in the Austrian and Hungarian archives. My research draws on Szepessy's appeals to Köprülü; his correspondence with fellow Protestant nobles, family, and Transylvanian supporters; reports of Habsburg spies; dispatches of Habsburg residents at the Porte; and deliberations of the Habsburg War Council. Taken together these sources open a window on the life of an important trans-imperial subject whose life throws into question the clash of civilizations narrative that still dominates much of Habsburg and Central European historical studies.
Introduction
Authors: Yılmaz Yasir 
Published: September 2024

AbstractThe Third International Süleymaniye Symposium explored the Köprülü Era (1656-1710) in Ottoman history, emphasizing new sources and approaches. Scholars from Turkey, Europe, and the U.S. convened to examine the Köprülü grand viziers’ careers and times. In the current special focus section, Yasir Yılmaz, Halef Cevrioğlu, Elizabeth Lobenwein, Georg B. Michels, and Christopher Whitehead offer innovative perspectives, drawing on brand new archival material. We advocate for a comparative approach to the Ottoman grand vizierate, highlight the significance of Habsburg archives in Ottomanist scholarship, debunk new short-term and long-term historical dimensions in the making of the family, and ask new questions about how we should interpret the Köprülü expansionism.
