AbstractGiven a polynomial f over the finite field $$\mathbb {F}_q$$

F
q

, its intersection distribution provides fruitful information on how lines in the affine plane intersect the graph of f over $$\mathbb {F}_q$$

F
q

. The intersection distribution in its simplest cases gives rise to oval polynomials in finite geometry and Steiner triple systems in design theory. Previously, the intersection distribution of degree two and degree three polynomials has been computed. In this paper, we determine the intersection distribution of all degree four polynomials over finite fields. As an application, we present a direct construction of Steiner systems using polynomials with prescribed intersection distribution.
Internationalization pathways of sharing economy companies
Authors: Thornton Heidi Coral , Parente Ronaldo 
Published: October 2024

AbstractThe past decade has seen a global surge of sharing economy companies (sharecoms) engaged in increasing cross-border activities. However, the process by which they internationalize remains under-theorized. Addressing this gap, we present new, empirically driven insights into how sharecoms expand internationally. Through a qualitative multi-case study investigation, we discover that sharecoms internationalize through a combination of passive and active means, allowing them to increase their scale and scope simultaneouly—a strategy that constrasts with the processes posited in existing internationalization literature. We identify three key internationalization patterns adopted by sharecoms: the Maximizer, the Optimizer, and the Penetrator. Additionally, we devise a framework of both theoretical relevance to scholars and practical relevance to sharecom founders and managers.
Understanding the Dynamics of Hedonic and Eudaimonic Motives on Daily Well-Being: Insights from Experience Sampling Data
Authors: van Halem Sjoerd , van Roekel Eeske , Denissen Jaap 
Published: October 2024

AbstractPrevious studies have consistently found that hedonic and eudaimonic motives positively predict subjective well-being. In this study, we emphasized the importance of considering curvilinear effects alongside main effects and interactions to fully understand these relationships. Using polynomial regression models, we examined the relationships between hedonic motives, eudaimonic motives, and subjective well-being. To examine both trait-level and momentary-level relations with well-being, we used experience sampling methodology to collect real-time data from 161 participants over a 7-day period. Our findings suggested that engaging in activities towards fulfilling both motives was associated with positive experiences, and individuals with high levels of hedonic and eudaimonic motives in their daily lives generally reported higher subjective well-being. Nevertheless, we also identified negative interaction effects between both motives on subjective well-being, which imply that there may be a limit to the positive contributions of combinations of both motives to subjective well-being. We discuss the implications of our findings for understanding the nuanced relationships between hedonic and eudaimonic motives and subjective well-being.
Against Exclusionary Reasons as Only Razian Facts
Authors: Gálvez Bermúdez Carlos 
Published: October 2024

Abstract
Legal rules are often understood in terms of exclusionary reasons, and exclusionary reasons are normally understood as reasons for action according to Raz. In this paper, I engage with the literature on the metaphysics of reasons for action and explain how exclusionary reasons can be used in different conceptions of what reasons for action are (and not only by the one defended by Joseph Raz). To do that, I proceed as follows: In the first part, and after differentiating between factual and psychological conceptions of what reasons for action are, I engage with different approaches to reasons for action as facts (such as those claiming that reasons are explanation or evidence of “oughts”, primitive facts, and value-based instrumental and non-instrumental facts) to defend that exclusionary reasons can be accommodated inside all of those factual conceptions of reasons for action. In the second part, I engage with those claiming that reasons for action are grounded in mental states (such as will, desires, beliefs, and intentions) to explore whether exclusionary reasons can work inside those psychological conceptions of what reasons for action are. As a result, by showing how exclusionary reasons can be accommodated inside different factual and psychological conceptions of what reasons for action are, I defend that exclusionary reasons are an open concept that is not conceptually linked to Raz’s conception of what reasons for action are.
Shaping New Aims and Practices of Teaching Controversial Issues in Response to Conservative Critics
Authors: Stitzlein Sarah M. 
Published: October 2024

Abstract
While the teaching of controversial issues has generally been supported by schools and education scholars, new laws and public outcry have impacted whether and how controversial issues are taught. Calls to ban or limit teaching of controversial issues have largely been spurred by conservative parents, policymakers, and political groups. Some teachers and many education scholars are deeply concerned and want to preserve teaching about controversial issues. This situation suggests that inquiry is needed into changes in the educational aims held and practices endorsed by various stakeholders. This article reconsiders the aims used to justify teaching controversial issues and situates them within larger understandings of good citizenship, revealing important differences in the explanations and values endorsed by opposing groups. It categorizes the aims more generally held by teachers, philosophers of education, and citizenship education scholars as: reasoning, engaging, communicating, and sustaining democratic communities. Then, those aims are compared to aims circulating within the discourse of opposing parents, policymakers, and political organizations. Finally, this article argues that pragmatic adjustments to educational aims held by many teachers and education scholars are both warranted and wise. It provides potential ways to better justify the teaching of controversial issues, including through approaches that more strongly ground teaching in American principles, historical examples, and a commitment to living together well.
Application of Analytical Solutions of the Reactive Transport Equation for Underground Methanation Reactors
Authors: Hagemann Birger , Hogeweg Sebastian , Strobel Gion 
Published: October 2024

AbstractFluctuations in the production of renewable-based electricity have to be compensated by converting and storing the energy for later use. Underground methanation reactors (UMR) are a promising technology to address this issue. The idea is to create a controlled bio-reactor system in a porous underground formation, where hydrogen obtained from renewable energy sources by electrolysis and carbon dioxide from industrial sources are fed into the reactor and converted into methane. Microorganisms, known as methanogenic archaea, catalyze the chemical reaction by using the two non-organic substrates as nutrients for their growth and for their respiratory metabolism. The generated synthetic methane is renewable and capable to compete with the fossil methane. Mathematical models play an important role in the design and planning of such systems. Usually, a numerical solution of the model is required since complex initial-boundary problems cannot be solved analytically. In this paper, an existing bio-reactive transport model for UMR is simplified to such an extent that an analytical solution of the advection-dispersion-reaction equation can be applied. A second analytical solution is used for the case without dispersion. The analytical solutions are shown for both the educt (hydrogen) and the reaction product (methane). In order to examine the applicability of the analytical models, they are compared with the significantly more complex numerical model for a 1D case and a 3D case. It was shown that there is an acceptable agreement between the two analytical solutions and the numerical solution in different spatial plots of hydrogen and methane concentration and in the methane concentration in the withdrawn gas. The mean absolute error in the mole fraction is well below 0.015 in most cases. The spatial distribution of the hydrogen concentration in the comparison to the 3D case shows a higher deviation with a mean absolute error of approx. 0.023. As expected, the model with dispersion shows a slightly lower error in all cases, as only here the gas mixing resulting in smeared displacement fronts can be represented. It is shown that analytical modeling is a good tool to get a first estimation of the behavior of an UMR. It allows to help in the design of well spacing in combination with the injection rate and injected gas composition. Nevertheless, it is recommended to use more complex models for the later detailed analysis, which require a numerical solution.

Abstract
Purpose
Accurate clinical staging of potentially resectable pancreatic ductal adenocarcinoma (PDAC) is critical for establishing optimal treatment strategies. While the efficacy of fluorine-18-fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) in clinical staging is unclear, PET/CT detecting fibroblast-activation protein (FAP) expression has recently received considerable attention for detecting various tumors, including PDAC, with high sensitivity. We explored the efficacy of [18F]FDG and [18F]AIF-FAPI-74 PET/CT in the initial evaluation of potentially resectable PDAC.

Procedures
Between 2021 and 2022, twenty participants with newly diagnosed potentially resectable PDAC were enrolled. After the initial evaluation with pancreatic CT, [18F]FDG PET/CT, and [18F]AIF-FAPI-74 PET/CT, treatment strategies were determined considering the participant’s general status, clinical staging, and resectability. Pathological information from the surgical specimens was only available in 17 participants who underwent curative-intent surgery. Head-to-head comparisons of quantitative radiotracer uptake and diagnostic performance were performed among imaging modalities.

Results
[18F]AIF-FAPI-74 PET/CT showed a significantly higher maximum standardized uptake value than [18F]FDG PET/CT did in evaluating primary pancreatic lesions (median [interquartile range]; 12.6 [10.7–13.7] vs. 6.3 [4.8–9.2]; P < 0.001). In contrast, [18F]AIF-FAPI-74 PET/CT showed a significantly lower mean standardized uptake value than [18F]FDG PET/CT did in evaluating background organ (median [interquartile range]) 0.8 [0.7–0.9] vs. 2.6 [2.3–2.7]; P < 0.001). In addition, the sensitivity of [18F]AIF-FAPI-74 PET/CT in detecting metastatic lymph nodes was higher than that of [18F]FDG PET/CT (50.0% vs. 0.0%; P = 0.026).

Conclusion
This study demonstrated that [18F]AIF-FAPI-74 PET/CT could improve the clinical staging of potentially resectable PDAC.
Forest Owner Attitudes Toward Climate-Proof Forest Management in Sweden and the Netherlands—Between Forest Strategies and Practical Measures
Authors: Sikkema Richard , Wilhelmsson Erik , Ellison David , Petersson Hans 
Published: October 2024

AbstractOur research targets the role of forests under the international Paris Climate Agreement, the EU Green Deal and Forest Strategy. In line with the latter objectives, Member States are expected to encourage forest owners to contribute to international climate goals via national strategic plans and new management measures. How forest owners will respond, however, to a range of climate smart forestry (CSF) measures in the near future, is not well known. After postal and email distribution in 2020, 98 Swedish (response rate 21%) and 241 Dutch forest owners (24%) filled out a forest-climate survey. Based upon specific CSF measures, several hypothetical climate-related scenarios were incorporated into the survey. Dutch forest owners are planning to introduce new tree species, more mixed species stands (a gradual shift to broadleaved species) and additional water reservoirs in anticipation of increased drought periods, all part of a hypothetical climate adaptation package for 2030. Swedish forest owners prefer earlier thinning and salvaging activities. Zooming in on Dutch scale differences, small forest owners rely less on current public subsidy packages and show significantly less interest in committing to the adaptation package than large forest owners. In Sweden, preferences for the high forest management intensity scenario is significantly affected by size class: more intensive activities are the least popular with the smallest forest owners. The greatest difference between both countries is the way in which CSF measures should be financially supported. In general, Dutch forest owners would prefer to maintain subsidy schemes but adapt them to new circumstances, while Swedish forest owners benefit from timber and bioenergy markets.
A Convergent Semi-Lagrangian Scheme for the Game $$\infty $$-Laplacian

AbstractWe propose a new semi-Lagrangian scheme for the game $$\infty $$
∞
-Laplacian. We demonstrate the convergence of the scheme to the viscosity solution of the given problem, showing its consistency, monotonicity, and stability. The proof of this result is established following the Barles-Souganidis analysis. This analysis assumes convergence at the boundary in a strong sense and is applied to our proposed scheme, augmented with an artificial viscosity term.
Beekeeping and agropastoralism interactions through floral resources in the French Mount Lozère
Authors: Gonella Gabriel , Leoni Estelle , Mouillard-Lample Léo , Aubron Claire , Decourtye Axel , Deconchat Marc , Barnaud Cécile 
Published: October 2024

AbstractBeekeeping has faced increasing difficulties during the past decades, among which is the decline in floral resources. Agriculture provides essential floral resources for beekeeping, but some farming practices have also been shown to be responsible for their decline. To provide floral resources for beekeeping, what type of agricultural transformation should be promoted, and how? To answer these questions, we still lack knowledge about the floral resources that are used by beekeeping and about the technical-economic obstacles that farmers face in implementing more favorable farming practices, particularly in agropastoral settings. To help fill these gaps, we develop a novel approach that frames both agropastoral farming and beekeeping as farming systems, by characterizing the beekeeping systems of a given place, the floral resources they use, and the impacts these farming systems have on floral resources. This approach is applied to the agropastoral landscapes of Mount Lozère, southern France, using a methodology based on semi-structured interviews with farmers and beekeepers addressing the agronomical functioning of their farms. We demonstrate that the floral resources used by beekeepers on Mount Lozère are threatened by the current dominant agricultural development paths, which seek to maximize the material productivity of labor. Such paths lead to the intensification of agricultural practices in harvested areas and the extensification of rangelands. These pathways are reinforced by the low remuneration of agropastoral labor and by the current rules of the European Union Common Agricultural Policy. “Frugal” farming, a farming system based on reduced inputs and investments, and labor-intensive practices, namely, a labor-intensive use of pasture, seems an effective way to produce floral resources. Both, agropastoral farmers and beekeepers, would benefit from an increase in the number of agricultural workers in agropastoral landscapes. This calls for public policies that promote a better remuneration of agropastoral labor, either directly or by driving market mechanisms.
ProbFuzzOnto: A Fuzzy Ontology-Driven Uncertainty Approach Using Fuzzy Bayesian Networks
Authors: Riali Ishak , Fareh Messaouda , Bobillo Fernando 
Published: October 2024

Abstract
The need to deal with uncertain semantics is rising in importance in most of the important technology trends, and consequently, many proposals have emerged as solutions in recent years. Fuzzy ontologies were proposed to remedy the limitations of standard ontologies using fuzzy logic to deal with vague and imprecise knowledge. Nevertheless, fuzzy ontologies cannot deal with probabilistic knowledge which is an important characteristic of most real-world applications. This paper proposes a novel solution that aims at enhancing the knowledge representation and reasoning in fuzzy ontologies. Indeed, the proposed solution is a probabilistic extension of fuzzy ontologies with Fuzzy Bayesian Networks (FBN) that we named Probabilistic Fuzzy Ontologies (ProbFuzzOnto). It takes into account vague, imprecise, and probabilistic knowledge simultaneously. Moreover, this paper proposes a process to guide ontology engineers step by step in building ProbFuzzOnto. Also, it provides reasoning algorithms to drive implicit knowledge by utilizing explicit knowledge stored in a fuzzy ontology based on fuzzy Bayesian inference. To show the usefulness of the proposed solution, a case study in Renal Cancer is presented.
Measuring the Collective Community Capacity of a Network to Address Health Inequities during a Public Health Emergency: Findings from the National COVID-19 Resiliency Network

Published: October 2024

Abstract

Objective
This study assesses the collective community capacity of the National COVID-19 Resiliency Network (NCRN), a multisectoral network mitigating the disproportionate impact of COVID-19 on minoritized populations.

Methods
From January to April 2022, we used two concurrent data collection methods: a Collective Community Capacity (C3) survey (n=65) and key informant interviews (KIIs) (n=26). The C3 assessed capacity for creation of a shared vision, engagement in community change, and distributive leadership. KIIs assessed perspectives on network formation and implementation. We used a convergent design and triangulation for interpretation.

Results
NCRN has growing collective community capacity. The C3 survey found high capacity for establishing a shared mission and evidence of mutual commitment, trust, and accountability. About three-quarters of respondents strongly agreed that partners addressed social, economic, and cultural barriers related to COVID-19. Interviewees valued NCRN leaders’ openness, availability, and willingness to listen. Partners learned from one another, increased their health communication capacity, and supported sustainability. They sought greater opportunities to partner and support decision-making.

Conclusions
NCRN developed a collaborative network with a shared vision of improving health equity during and beyond the COVID-19 pandemic, while identifying areas for improvement in distributive leadership. Findings can support other organizations seeking to build collective community capacity to address equity in public health emergencies.
Viewing Violence through a Partisan Lens: How Electoral Violence Shapes Citizens' Support for Democracy
Authors: Fjelde Hanne , Olafsdottir Gudlaug 
Published: October 2024

Abstract
In many elections across the world, the regime in power uses violence to influence electoral dynamics and outcomes. What is the effect of such violence on citizens' attitudes to democracy? We argue that the effect of government-perpetrated electoral violence on citizens' democratic commitment will diverge depending on whether the individual supports the ruling or opposition party. While those affiliated with the opposition should become more likely to support democracy in the wake of government violence, we expect those affiliated with the incumbent to support more power concentrated in the hands of the executive. We examine these expectations using cross-national, geo-referenced survey data from the Afrobarometer, alongside event data on electoral violence. We find that while incumbent supporters generally display lower baseline support for democracy in the absence of violence, violent elections do not further erode their democratic commitment. Violence is, however, associated with increased support for democracy amongst opposition supporters.

Trade, Slavery, and State Coercion of Labor: Egypt during the First Globalization Era
Authors: Saleh Mohamed 
Published: October 2024

AbstractI investigate the effects of trade on labor coercion under the dual-coercive institutions of slavery and state coercion. Employing novel data from Egypt, I document that the cotton boom in 1861–1865 increased both imported slaveholdings of the rural middle class and state coercion of local workers by the elite. As state coercion reduced wage employment, it reinforced the demand for slaves among the rural middle class. While the abolition of slavery in 1877 increased wages, it did not affect state coercion or wage employment. I discuss the political effects of the abolition as a potential explanation for these findings.“The barbarism of the [U.S.] South, while destroying itself, [appeared] in the providence of God to be working out the regeneration of Egypt.”North American Review 98, no. 203 (1864, p. 483), quoted in Earle (1926)
Party ideology in Nigeria's Four Republics: a case of right-wing convergence
Authors: Husaini Sa'eed A. 
Published: October 2024

ABSTRACTDo Nigerian political parties take left/right ideological positions? Perspectives in comparative politics see party competition in Africa's ‘third wave’ democracies as devoid of disagreement on class or economic grounds – and thus as ‘absent’ of left/right ideology. Yet, a dearth of disagreement among governing parties can also suggest ideological agreement or ‘convergence’. This article maps the development of the left/right cleavage in Nigeria's party system, examining the evolution of economic pledges in the manifestos of parties that took power across Nigeria's four attempts at electoral democracy. It finds that relative to the deeper levels of economic disagreement voiced in earlier periods, the governing parties of Nigeria's Fourth Republic are now largely unanimous in the enunciation of their economic visions. Evidence of such convergence troubles a strict insistence on either the polarisation or ‘absence’ of economic ideology among governing parties in Africa's largest electoral democracy.
