Ptolemy presents only one argument for the eccentricity in his models of the superior planets, while each one of them has two eccentricities: one for center of the uniform motion, the other for the center of the constant distance. To take into account the first eccentricity, he introduces the equant point, but he provides no argument for the eccentricity of the center of the deferent. Why is the second eccentricity different from the first one? The 13 th century astronomer Quṭb (...) al-Dīn al-Shīrāzī, a member of the famous school of Marāgha, who was interested in this problem, suggests the “retrograde arcs” as the empirical origin of the second eccentricity and develops an argument to justify this conjecture. Although his argument is not without difficulty, his suggestion is in line with the suggestions made by some historians of astronomy in recent decades. Résumé Ptolémée ne donne qu'un seul argument pour expliquer dans son système l'excentricité des planètes supérieures, alors que chacune d'elles a deux excentricités: l'une par rapport au centre du mouvement uniforme, l'autre par rapport au centre de la distance constante. Pour rendre compte de la première excentricité, il introduit le point équant, mais il ne donne en revanche aucun argument pour l'excentricité par rapport au centre du cercle déférent. Or, pourquoi la seconde excentricité est-elle différente de la première? Quṭb al-Dīn al-Shīrāzī, astronome du xiii e siècle membre de l'école de Marāgha, qui s'est intéressé à cette question, a fait l'hypothèse que les “arcs de rétrogradation” constituent l'origine empirique de cette seconde excentricité. Bien que l'argument sur lequel il appuie cette hypothèse ne soit pas exempt de difficultés, sa suggestion rejoint celles faites par des historiens de l'astronomie durant les dernières décennies.

Critical realism has a reputation for requiring substantial intellectual commitment and time to gain understanding, and being difficult to operationalize as an empirical research methodology. Our paper employs the theoretical framework of ‘threshold concepts’ to explore these issues. We illustrate the five qualities of ‘threshold concepts’ using existing literature by scholars describing their journey of engagement with critical realism. We then apply the framework from three viewpoints. First, we offer the perspective of a budding critical realist scholar who transforms their (...) understanding through reflexivity. Second, we consider the role of critical realist communities of practice, peer-to-peer and social learning. Finally, we look from the standpoint of a more experienced critical realist academic advisor or supervisor working with a student. The paper concludes by asking: what kind of learning and teaching frameworks of engagement can the critical realist community build to better support apprentice critical realists? (shrink)

This paper sketches the antilogism of Christine Ladd-Franklin and historical advancement about antilogism, mainly constructs an axiomatic system Atl based on first-order logic with equality and the wholly-exclusion and not-wholly-exclusion relations abstracted from the algebra of Ladd-Franklin, with soundness and completeness of Atl proved, providing a simple and convenient tool on syllogistic reasoning. Atl depicts the empty class and the whole class differently from normal set theories, e.g. ZFC, revealing another perspective on sets and set theories. Two series of Dotterer (...) and the theorem proved by Russinoff are re-characterized in antilogistic formulas corresponding to the square of opposition and twenty-four moods of syllogism. Then the restricted equivalence between two forms of antilogism and minimal inconsistency is built up, implying the internal connection between antilogisms and minimal inconsistency and leaving two related conjectures not proved. Besides, this paper provides a new explanation for the reason why contrariety, subcontrariety, and subalternation and the nine special moods require the non-empty assumption. (shrink)

Climate change and environmental degradation are threatening the existence of humanity. The youth have the potential and capability to play a pivotal role in tackling these challenges. Therefore, the current study aims to examine how school and family environmental education can enhance environmental knowledge, willingness to take action, and pro-environmental behaviors among children and young people. The Bayesian Mindsponge Framework (BMF) analytics was utilized on a nationally representative dataset of 2069 Vietnamese primary, secondary, and high school students. The (...) analysis results suggest that school and family environmental education is beneficial for improving students’ environmental knowledge and willingness to take environmental actions. Notably, the effect of school education is more substantial for cultivating environmental knowledge, whereas family education has a stronger impact on raising students’ willingness than school education. Students with higher levels of environmental knowledge are more likely to conduct pro-environmental behaviors only when they are willing to take environmental actions. If students are unwilling to act, higher environmental knowledge is negatively associated with the likelihood of pro-environmental behavior. Following these findings, we call for coordinated education efforts of schools and families to cultivate students’ eco-surplus culture. The education efforts should be implemented along with exposing students to environmental settings and encouraging them to read environmental books. (shrink)

Background: The feeding modalities applied in countries with school meal programs are varied because these are shaped not only by the national commitments to alleviate food insecurity among children but also by resource availability from national and international agencies. In terms of financial resources, the USA plays a consistent role in providing donations, grants, loans, and loan guarantee programs to support global school feeding. The U.S. Department of Agriculture (USDA) oversees these funding sources for international school meal (...) programs. Aim: This study aims to examine the moderating effect of USDA funding on the relationship between supply purchasing methods and feeding modalities among countries implementing school meal programs. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: The findings indicated that USDA funding has the potential to positively moderate the relationship between foreign supply purchases and the feeding modalities of school meal programs. However, the direct association between foreign purchases and feeding modalities was unclear. Conversely, while USDA funding was found to have a negative moderation effect on the relationship between domestic supply purchases and feeding modalities, it is these domestic purchases that show potential for positively influencing the feeding modalities. Conclusions: Findings underscore the importance of supporting the World Bank and World Food Programme’s recommendation to rely more on local resources and capacities for developing long-term and sustainable school meal programs. Further exploration of the impact of foreign supply purchases on feeding modalities is needed. Formulating strategic plans to better leverage USDA funding for enhancing domestic supply purchases is highly recommended. (shrink)

Background: Food insecurity condition challenges the availability of food, access to food, food supply stability, and food utilization. Food banks play a major role in the food aid sector by distributing donated and purchased groceries directly to food-insecure families, thus significantly impacting food insecurity. On the other hand, school meal programs are implemented in many countries to combat food insecurity among school-aged children. The synergy between school meal programs and food banks has a great potency to combat (...) food insecurity among children effectively. Aim: This study aims to examine the association between experts’ involvement—such as nutritionists, farmers, and private sectors—and community engagement, including parents and others, with the linkage between food banks and school meal programs among implementing countries. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the involvement of nutritionists and the private sector was positively associated with the linkage between food banks and school meal programs, while farmers’ involvement showed an ambiguous association. The engagement of parents and others also showed an ambiguous relationship with this linkage. Conclusions: Findings underscore the strong need to formulate strategies for increasing the involvement of nutritionists and the private sector to successfully link the food banks with school meal programs in implementing countries, which is crucial for effectively combating food insecurity among school-aged children.

Background: School meal programs are not only government initiatives but also community-driven efforts. Aiming to combat food insecurity among school-aged children effectively, these programs are executed in conjunction with food bank initiatives. Various community groups play a crucial role in the success of both food security initiatives. There is a need to improve community engagement to successfully link school meal programs with food banks to build program synergy, combating food insecurity through a two-sided approach. Aim: This study (...) aims to examine community engagement in school meals program by analyzing its purposeful focus on creating jobs and income-generating opportunities for different community groups, i.e., youths, women, and others. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the school meals program’s purposeful focus on creating jobs and income-generating opportunities for women in the community was positively associated with community engagement, thereby supporting the linkage between the programs and food banks. In contrast, providing jobs and income-generating opportunities for youths and other community groups had an ambiguous association with community engagement in school meal programs. Conclusions: Findings underscore the importance of creating jobs and income-generating opportunities for women to improve community engagement in school meal programs. Formulating strategies that empower woman’s entrepreneurship may foster their involvement and engagement in school meal programs, promising to successfully link these programs with food bank initiatives among implementing countries.

One of the greatest philosophical disputes in Germany in the latter half of the nineteenth century concerned the value of life. Following Arthur Schopenhauer, numerous philosophers sought to defend the provocative view that life is not worth living. A persistent objection to pessimism is that it is not really a philosophical theory at all, but rather a psychological state; a mood or disposition which is the product of socio-economic circumstance. A developed and influential version of this view was advanced in (...) the 1870s by the English psychologist James Sully. Yet, as important as Sully's critique was for the pessimism dispute, it has been almost entirely overlooked in the history of philosophy. With some growing recent attention to nineteenth-century pessimism, this paper aims to reconstruct Sully's view, and what I argue is his primary argument for it in terms of the best explanation for an alleged historical correlation between pessimistic belief and social hardship in the form of frustrated ideals. The paper then presents and analyses some challenges to this argument, some of which are argued to have been at least partially anticipated in the nineteenth-century by the likes of Schopenhauer and Olga Plümacher.

In this volume, Maher contextualizes the work of a group of contemporary analytic philosophers—The Pittsburgh School—whose work is characterized by an interest in the history of philosophy and a commitment to normative functionalism, or the insight that to identify something as a manifestation of conceptual capacities is to place it in a space of norms. Wilfrid Sellars claimed that humans are distinctive because they occupy a norm-governed "space of reasons." Along with Sellars, Robert Brandom and John McDowell have tried (...) to work out the implications of that idea for understanding knowledge, thought, norms, language, and intentional action. The aim of this book is to introduce their shared views on those topics, while also charting a few key disputes between them. (shrink)

The tendency to get involved in helping one’s family, friends, school, and community has many potential benefits such as greater compassion, concern for others, and social responsibility. Research interest in the benefits of contribution in adolescents has increased recently, but there are not many studies examining the effect of contribution on adolescents’ mental health. The present study focused on whether the contribution is associated with fewer self-rated depression symptoms in adolescents. We further tested whether self-regulation and academic performance can (...) have a mediating role in this association. A total of 423 secondary school students (233 female) from eastern Croatia participated in the study. Mean age was 16.78 (SD= 1.21). Students completed measures of self-regulation, depression symptoms, and contribution (helping one’s family, friends, or neighbors, mentoring peers, volunteering in one’s community, and participating in school organizations or boards), and gave information about age, gender, and academic performance. A hierarchical regression analysis revealed that contribution, self-regulation, and academic performance were related with lower levels of self-rated depression symptoms. Furthermore, mediation analysis indicated a significant indirect effect through two mediators, self-regulation and academic performance, which was stronger than a path containing only self-regulation. Academic performance alone was not a significant mediator. Our findings suggest that contribution could protect against depression by promoting self-regulation, leading to higher academic performance, and consequently fewer depression symptoms. (shrink)

Immigrant and refugee presence in western nation-states challenges symbolic national boundaries and is perceived as a threat to the dominant majorities. In this context, hate speech is reinforced in the form not only of violent racist acts (hard hate speech) but mostly of mitigated rejection and covert discriminatory practices (soft hate speech). In both cases, hate speech draws on and simultaneously entrenches national discourse aiming to represent the nation as a linguaculturally homogeneous entity. Studies concentrating on hate speech usually investigate (...) public discourse produced by adults. The present study explores the reproduction of (soft) hate speech among immigrant students within the Greek educational context. Adopting a critical discourse-analytic perspective, we employ analytical tools from the Discourse-Historical Approach allowing us to trace how specific discursive strategies contribute to the reproduction of soft hate speech, which seems to draw on national discourse in the form of either racist discourse or humanitarian discourse.

Commercial video games are popular entertainment media and part of students’ media reality. While commercial video games’ main purpose is not learning, they nonetheless could and should serve as objects of reflection in formal educational settings. Teachers could guide student learning and reflection as well as motivate students with commercial video games, but more evidence from formal educational settings is required. We conducted two mixed methods case studies to investigate students’ reflection processes using commercial video games in regular formal high (...) school teaching. In a double lesson, 29 students of a 10th-grade biology course and 17 students of a 12th-grade advanced course on history played and discussed a commercial video game related to the current curricular topic. We examined the reflection processes of students in terms of their reactions to the teachers’ game-related statements and questions. Regarding teachers’ statements, students discussed several topics related to game enjoyment and the games’ representation of topic-related content. Regarding teachers’ questions, students discussed multiple goals in each game, how the games represented topic-related content, and how the games could be appropriate for learning. In Study 2, students additionally discussed emotions, stereotypes, violence, and the narrative related to the digital history game. We found that the discussions provided students opportunities to reflect on their game experiences and the current curricular topic as well as to practice media criticism. We further provide quantitative results on students’ perceived topic knowledge, on several facets of their learning motivation, and on their acceptance of video games. Overall, our findings illustrate the educational value of using commercial video games as objects of reflection. (shrink)

Zoos attract millions of visitors every year, many of whom are schoolchildren. For this reason, zoos are important institutions for the environmental education of future generations. Empirical studies on the educational impact of environmental education programs in zoos are still rare. To address this issue, we conducted two studies: In study 1, we investigated students’ interests in different biological topics, including zoos ( n = 1,587). Data analysis of individual topics revealed large differences of interest, with advanced students showing less (...) interest in zoos. In study 2, we invited school classes of this age group to visit different guided tours at the zoo and tested connection to nature before and after each educational intervention ( n = 608). The results showed that the guided tours are an effective tool to raise students’ connection to nature. Add-on components have the potential to further promote connection to nature. The education programs are most effective with students with a low initial nature connection. (shrink)

Around the world, many schools were closed as one of the measures to contain the spread of the COVID-19 pandemic. School closure brought about important challenges to the students' learning process. This context requires strong self-regulatory competences and agency for autonomous learning. Moreover, online remote learning was the main alternative response to classroom learning, which increased the inequalities between students with and without access to technological resources or for those with low digital literacy. All considered, to level the playing (...) field for students without digital resources, there is an urgent need to promote self-regulatory competences through offline intervention solutions. The current paper describes a project with this purpose, using radio broadcasting and letters to reach elementary students without digital resources. Moreover, potential reach and participants' perspectives of the project implementation are presented and discussed. The project draws on a prior evidence-based story-tool intervention grounded on a self-regulated learning framework. The original intervention was set previous to the COVID-19 pandemic and was implemented in the classroom context (N= 1,103 students). Once the schools had been closed down, the mode of intervention was adapted with the collaboration of the community. Alternative solutions were developed as follows: (i) story chapters were read on the radio and students received to their homes a printed script, prompting reflection, and suggesting related activities; (ii) students were provided with the story-tool to read autonomously and received letters from the main characters of the story which included, for example, suggestions for activities and reflection. These two alternative modes of intervention delivery potentially reached 394 elementary students, including students with digital resources. Interviews conducted with a group of students were provided information about the positive aspects of these two modes of intervention delivery, perceived learning (e.g., planning), constraints, and suggestions to improve the project. The current work is likely to merit attention from researchers and educational practitioners, given the need to use offline alternatives to provide support for students without digital resources to engage in autonomous learning during the pandemic period. This project may also be used as an alternative or a complementary solution to online modality. (shrink)

Despite all methodological efforts made in the last three decades, Western instruction grounds on traditional principles. Most educational programs follow theories that are mentalistic, i.e., they separate the mind from the body. At school, learners sit, watch, listen, and write. The aim of this paper is to present embodied learning as an alternative to mentalistic education. Similarly, this paper wants to describe embodied learning from a neuroscientific perspective. After a brief historical overview, I will review studies highlighting the behavioral (...) effectiveness of embodied instruction in second language learning, mathematics and spatial thinking. On this base, I will discuss some of the brain mechanisms driving embodied learning and describe its advantages, clearly pleading in favor of instructional practice that reunites body and mind.

In the Confucian tradition, sages are moral reference points. They may serve as models against which we measure our own behaviours, and help us imagine how we can improve the quality of our moral lives. This defining feature of Confucian philosophy has persisted though the subsequent development of the tradition to the present. Yet, little has been said about the important epistemological issues that underlie the Confucian modelling process. In order to uphold sages as moral reference points, people need to (...) recognize sages as sages and to deem the ways in which their lives embody virtue as desirable. This paper draws on a form of knowing, namely, knowing-as, to illuminate the process of learning from sages in the Confucian tradition. It will also help us better understand the process of modelling more generally. (shrink)

This article seeks to critically question the internal logic and coherence of ‘anti-doping’ through the case study of advantage-seeking practices in the sport of Brazilian Jui-Jitsu (BJJ). We provide an analysis of the recent controversy between high-profile fighters Gordon Ryan and Nicky Rod involving the relative morality of image and performance enhancing drug (IPED) use compared with ‘greasing’, whereby BJJ athletes apply substances, such as oil or lubricants, to the body to make it harder for opponents to establish a grip (...) or maintain control during grappling exchanges. We employ this case study to highlight the impasse between the World Anti-Doping Agency’s (WADA) ethical foundation of the ‘spirit of sport’ and the anti-doping industry’s ‘anti-policy’ stance. We then query why a host of non-chemical advantage-seeking practices are normalised and overlooked within the rigid and constrictive systems. Ultimately, we characterise WADA as a myopic compliance system that stifles moral debate around advantage-seeking in sport and is hamstrung by an ethical discord between anti-policy and the neo-Aristotelian ideal of the spirit of sport. We close with a call for a holistic ethical understanding of advantage-seeking in sport and the need to encourage stakeholders to ‘think institutionally’ in order to establish a malleable and reactive response to doping.

Is traditional virtue epistemology a kind of idealised epistemology? Is that a bad thing? Some supporters of the virtue epistemology of liberatory virtues seem to answer these questions affirmatively. H. Battaly also argues that to avoid idealization virtue epistemologists should adopt a kind of normative contextualism according to which one and the same character trait is a virtue in some contexts, and a vice (or at least not a virtue) in other contexts. In this paper, I defend traditional virtue epistemology (...) against some, but not all, of these charges. I argue that the examples that motivate its critics are best explained by invoking particularism about actions rather than normative contextualism about character traits. I also show that a particularist virtue epistemology of inquiry provides an account of the difference that social circumstances and power relations make to epistemically virtuous (and vicious) conduct that is superior to those that can be offered by resorting to normative contextualism.

The problem of intentional identity, as originally offered by Peter Geach, says that there can be an anaphoric link between an indefinite term and a pronoun across a sentential boundary and across propositional attitude contexts, where the actual existence of an individual for the indefinite term is not presupposed. In this paper, a semantic resolution to this elusive puzzle is suggested, based on a new quantified intensional logic and game-theoretic semantics (GTS) of imperfect information. This constellation leads to an expressive (...) intensional language with a property of informational independence, argued to produce a purely semantic explication to intentional identity statements. One consequence is that various extra-logical and pragmatic factors become of secondary concern; it is possible to solve the puzzle by logico-semantic methods, albeit somewhat radically renewed ones.

In this article, I examine the inversion of essential cultural values, such as physical perfection and the sports spirit, in 20th-century Europe. Periods emerged when physical perfection, once celebrated, morphed into tools for eugenics, racial theories, and ideological segregation. Similarly, the sports spirit became entangled in political and ideological conflicts. I approach this through the Marxist lens of ‘base—superstructure’ relations, focusing on the biological ‘base’, often misinterpreted through social Darwinism. This base is not subject to dialectical changes, does not develop (...) spirally but remains a constant fundament of human existence. It anchors pre-human and human interactions centered on physical fitness and interpersonal competition rooted in sexual selection. From this premise, I propose a philosophical model progressing from the general to the specific, built on four levels. At its foundation lies the unchanging physicality-agonistic ‘base’. From this base emerge three enduring cultural ‘structures’: physical culture, agonistic culture, and the uniting of these two sports cultures. These structures produce two cardinal values—physical perfection and sports spirit—while also giving rise to inversive superstructures that veer toward cultural distortions. I connect these inversions to the influence of elite groups shaping public opinion, aligning this analysis with Antonio Gramsci’s theory of hegemony. In this last stage, this perspective finds synergy with traditional Marxism, highlighting the role of elites in steering societal values and cultural frameworks. (shrink)

The U.S. military is developing augmented reality (AR) capabilities for use on the battlefield as a means of achieving greater situational awareness. The superimposition of digital data—designed to expand surveillance, enhance geospatial understanding, and facilitate target identification—onto a live view of the battlefield has important implications for virtuous conduct in war: Can the soldier exercise practical wisdom while integrated into a system of militarized legibility? Adopting a virtue ethics perspective, I argue that AR disrupts the soldier’s immersion in the scene (...) such that he is blinded to features beyond those identified in advance by the military’s system of cybernetic judgment. I turn to Michael Walzer’s classic account of the “naked soldier” dilemma to illustrate how AR capabilities radically shrink the bounds within which the soldier can cultivate the capacity for right conduct. By transforming the ambiguous ethical matter of killing an enemy combatant into the straightforward application of a rule, AR hollows out the soldier’s potential for virtuous action. The “smart battlefield” leaves no space for deliberative judgments that transcend the technical and legal determinations already written into the soldier’s view of the scene. (shrink)

Following the Gaza events of 2023/24, this study examines how Palestinians understand mass death and mass destruction, exploring how can such a humanitarian catastrophe be framed within a coherent narrative. The focus is on the concept of sacrifice, analysed through a theoretical framework that distinguishes between meaningful sacrifices and absurd, meaningless deaths that categorises the victims as homo-sacer. Hence, this study aims to investigate the language and literature of the Palestinian people that regards to the 2023/24 Gaza events, and the (...) way it re-conceptualises the mass death and destruction and its victims, between the concepts of sacrifice and homo-sacer. A sample of 120 literary and creative texts from the cultural magazine ‘Fusha for Palestinian Culture,’,Footnote1 was examined using the methodology of thematic analysis. Four primary themes emerged from the texts: the active documentation, the speed and intensity of death and destruction, the form of death, namely handling of bodies and burial rituals, and lastly the implementation of myths from various traditions, including the duality of mythologising and demythologising Gaza and its inhabitants. I conclude that these four themes were elemental in the rhetoric process of sanctification of the mass and random death and destruction. (shrink)
