In this paper we consider the logics L(i,n) obtained from the (n+1)-valued Lukasiewicz logics L(n+1) by taking the order filter generated by i/n as the set of designated elements. In particular, the conditions of maximality and strong maximality among them are analyzed. We present a very general theorem that provides sufficient conditions for maximality between logics. As a consequence of this theorem, it is shown that L(i,n) is maximal w.r.t. CPL whenever n is prime. Concerning strong maximality (i.e. maximality w.r.t. (...) rules instead of only axioms), we provide algebraic arguments in order to show that the logics L(i,n) are not strongly maximal w.r.t. CPL, even for n prime. Indeed, in such case, we show that there is just one extension between L(i,n) and CPL obtained by adding to L(i,n) a kind of graded explosion rule. Finally, using these results, we show that the logics L(i,n) with n prime and i/n < 1/2 are ideal paraconsistent logics. (shrink)

There is a renewed interest amongst scholars in the practice of pil- grimage. Over the past two decades, pilgrim -/- numbers have risen significantly, whilst forms of ''implicit'' or ''alternative'' spirituality have gained visibility and now coexist with -/- organised religions, sometimes sharing the same ritualistic space. There is probably no better place to look at the coexistence of -/- old and new forms of ritual expression than in the Camino to Santiago. To better understand the meanings attributed to this (...) -/- pilgrimage, we undertook a survey with over 470 pilgrims at various locations along the Camino. The findings confirm that -/- individuals with various, often contrasting, motivations and expectations walk side by side on this pilgrimage route. We -/- suggest that the results cannot be read simplistically as either confirming a ''post-secularisation'' trend or a religious revival. (shrink)

We address Steel’s Programme to identify a ‘preferred’ universe of set theory and the best axioms extending ZFC by using his multiverse axioms MV and the ‘core hypothesis’. In the first part, we examine the evidential framework for MV, in particular the use of large cardinals and of ‘worlds’ obtained through forcing to ‘represent’ alternative extensions of ZFC. In the second part, we address the existence and the possible features of the core of MV_T (where T is ZFC+Large Cardinals). In (...) the last part, we discuss the hypothesis that the core is Ultimate-L, and examine whether and how, based on this fact, the Core Universist can justify V=Ultimate-L as the best (and ultimate) extension of ZFC. To this end, we take into account several strategies, and assess their prospects in the light of MV’s evidential framework. (shrink)

A holobiont is a composite organism consisting of a host together with its microbiome, such as a coral with its zooxanthellae. To explain the often intimate integration between hosts and their microbiomes, some investigators contend that selection operates on holobionts as a unit and view the microbiome’s genes as extending the host’s nuclear genome to jointly comprise a hologenome. Because vertical transmission of microbiomes is uncommon, other investigators contend that holobiont selection cannot be effective because a holobiont’s microbiome is an (...) acquired condition rather than an inherited trait. This disagreement invites a simple mathematical model to see how holobiont selection might operate and to assess its plausibility as an evolutionary force. This paper presents two variants of such a model. In one variant, juvenile hosts obtain microbiomes from their parents (vertical transmission). In the other variant, microbiomes of juvenile hosts are assembled from source pools containing the combined microbiomes of all parents (horizontal transmission). According to both variants, holobiont selection indeed causes evolutionary change in holobiont traits. Therefore, holobiont selection is plausibly an effective evolutionary force with either mode of microbiome transmission. The modeling employs two distinct concepts of inheritance, depending on the mode of microbiome transmission: collective inheritance whereby juveniles inherit a sample of the collected genomes from all parents, as contrasted with lineal inheritance whereby juveniles inherit the genomes from only their own parents. A distinction between collective and lineal inheritance also features in theories of multilevel selection. (shrink)

The authors developed this textbook in response to an increasing interest in ethics, and a growing number of courses on this topic that are now being offered in educational leadership programs. It is designed to fill a gap in instructional materials for teaching the ethics component of the knowledge base that has been established for the profession. The text has several purposes: First, it demonstrates the application of different ethical paradigms (the ethics of justice, care, critique, and the profession) through (...) discussion and analysis of real-life moral dilemmas that educational leaders face in their schools and communities. Second, it addresses some of the practical, pedagogical, and curricular issues related to the teaching of ethics for educational leaders. Third, it emphasizes the importance of ethics instruction from a variety of theoretical approaches. Finally, it provides a process that instructors might follow to develop their own ethics unit or course. * Part I provides an overview of why ethics is so important, especially for today's educational leaders, and describes a multiparadigm approach essential to practitioners as they grapple with ethical dilemmas. * Part II deals with the dilemmas themselves. Ethical dilemmas written by the authors' graduate students bring readers face-to-face with the kinds of dilemmas faced by practicing administrators in urban, suburban, and rural settings in an era full of complexities and contradictions. * Part III focuses on pedagogy and provides teaching notes for the instructor. The authors discuss the importance of self-reflection on the part of both instructors and students, and model how they thought through their own personal and professional ethical codes as well as reflected upon the critical incidents in their lives that shaped their teaching and frequently determined what they privileged in class.

This study aimed to determine the health practices among the secondary school teachers during the Covid-19 pandemic in Ichon National High School. This considered the socio - demographic profile of the teachers in terms of age, sex, civil status and teaching load and the extent of practice employed by the teachers in the said health dimensions. A total of 53 teachers from Ichon National High School participated as respondents in the evaluative method of research that consists in three parts questionnaires. (...) The statistical treatment used in the computation and analysis of gathered data to determine the socio-demographic profile of the respondents are the descriptive statistics such as frequency and percentage. As to the significance of health practices during COVID-19 pandemic, Kruskal Wallis and Mann-Whitney U test was used to analyze the significant differences on the extent of practices among the different health dimensions. The very high extent of the implementation on the health practices during COVID-19 pandemic shows that the teachers are frequently practiced the health practices. The highest mean in mental aspect is conclusive that teacher during the pandemic exert effort to stay healthy on this and other areas as well. It is recommended to conduct further study regarding on the health practices among the secondary school teachers. (shrink)

Comentaba en el Prólogo a la 1ª edición que nos cuesta distinguir las técnicas de los métodos y aceptar que la buena investigación clínica es la que se realiza con método riguroso. Este método reposa en cuatro pilares: que la pregunta o cuestión formulada sea relevante, que esté enunciada de manera precisa y operativa, que sea abordada o respondida con el mejor medio disponible en cada circunstancia, y que evite redundancias o repeticiones de cuestiones que ya han sido examinadas por (...) otros investigadores. Añadía que es imprescindible una dosis de curiosidad y de entusiasmo por lo que se examina. Como se ha dicho con frecuencia, el ensayo clínico es, entre los métodos de investigación clínica, el "patrón oro", el que, gracias a su característica inherente (la distribución aleatoria), está sujeto a menores posibilidades de sesgos. Esta consideración no ha cambiado. Sin embargo, mayor validez interna del método no implica mayor relevancia de los resultados obtenidos. Actualmente es común examinar protocolos de ensayos clínicos bien diseñados, cuyo "único" problema es que pretenden evaluar aspectos de escaso interés farmacológico, terapéutico, epidemiológico o sanitario. ¿Qué interés tiene la evaluación del quinto fármaco de una serie en una indicación para la que ya hay cuatro análogos que le han precedido en su desarrollo? ¿Qué interés tiene la evaluación de un nuevo hipocolesterolemiante o de un nuevo fármaco para la osteoporosis si no se conocen, respectivamente, el impacto de la hipercolesterolemia como factor de riesgo de cardiopatía isquémica o la epidemiología de las fracturas en mujeres postmenopáusicas en nuestro medio? En relación con estos ejemplos, tendría mucho más interés conocer los determinantes epidemiológicos y la historia natural de la cardiopatía isquémica en nuestro medio y conocer la epidemiología de las fracturas "espontáneas" y su impacto sobre la demanda asistencial; para ello serían de mucha utilidad métodos de investigación cuya validez intrínseca podría ser considerada "subóptima" en comparación con el ensayo clínico. En los últimos años ha irrumpido con fuerza en numerosísimas publicaciones el concepto de la "medicina basada en pruebas". Esta moda refleja en parte la importancia que de manera creciente reguladores e industria farmacéutica han concedido a los ensayos clínicos: se ha alcanzado un consenso global sobre la necesidad de demostrar la "eficacia" de los nuevos medicamentos por medio de ensayos clínicos controlados. De este modo, los organismos reguladores y autoridades sanitarias exigen ensayos clínicos como uno de los elementos necesarios para obtener el registro de un nuevo medicamento. Como consecuencia, se realizan y publican muchos más ensayos clínicos que antaño, y actualmente se pueden encontrar ensayos que sustentan la eficacia de la mayoría de los medicamentos disponibles en indicaciones específicas. Si hace unos años bastaba con examinar si había ensayos clínicos que demostraran la eficacia de un determinado medicamento antes de adoptarlo como uno de los de uso común (o de incluirlo en el formulario de un hospital), en la actualidad estas decisiones son más complejas, y se basan sobre todo en una consideración atenta de los objetivos, los métodos y los resultados de cada ensayo o de otros estudios destinados a evaluar eficacia, seguridad, conveniencia o comodidad y coste. Un buen clínico debe saber a la vez leer críticamente las publicaciones científicas y producir información relevante. Leer críticamente significa evaluar la pertinencia de los problemas investigados, los métodos aplicados y la interpretación de los resultados obtenidos. Producir información relevante implica saber identificar los problemas que deben y pueden ser objeto de investigación, formularlos, y ser protagonista (generalmente como parte de un equipo) de la elaboración del plan de investigación. En los últimos años se han publicado varios textos similares al que tiene en sus manos, todos ellos de gran calidad. El presente no pretende ser el más exhaustivo, sino sobre todo interesar a los profesionales sanitarios en el apasionante campo de la investigación clínica, en su sentido más amplio, estimulando la autonomía del lector para investigar un problema o una situación, y para aprender a leer las publicaciones científicas clínicas. Su lectura debe contribuir a que términos como "doble ciego", "p<0,05", "casos y controles", etc. dejen de ser fetiches-misterios, para convertirse en herramientas conceptualmente sencillas, útiles para la evaluación de la actividad asistencial. Esta nueva edición está muy ampliada respecto a la anterior. Se han reorganizado las generalidades sobre los objetivos y métodos de la investigación clínica, se han ampliado algunos aspectos del ensayo clínico, como el análisis de subgrupos, los aspectos estadísticos y éticos y las publicaciones sobre ensayos clínicos, se han añadido cuatro nuevos capítulos, sobre efectividad y eficacia, metaanálisis, ensayos en un solo paciente y farmacoeconomía, y el Glosario ha sido revisado y ampliado (sobre todo con términos de farmacocinética, desarrollo preclínico de fármacos, estadística y biotecnología genética), e incluye casi 750 términos. Para su elaboración me he basado en numerosos textos y diccionarios,a aunque he reformulado la mayoría de las definiciones y he optado por añadir en ocasiones algún comentario personal a muchas de ellas. Carles Vallvé ha escrito el capítulo sobre Normas de Buena Práctica Clínica. Agradezco asimismo las precisones y comentarios de Eulalia Dalmau, Javier Jiménez, Josep Maria Castel y Xavier Vidal, así como los comentarios a versiones anteriores de Fernando Antezana y Jorleny Rojas. Eduard Diogène me sugirió la idea de la portada, El sueño de la razón produce monstruos, que Goya comentaba así: " La fantasía abandonada de la razón produce monstruos imposibles: unida con ella es madre de las artes y origen de sus marabillas" La 1ª edición de este libro, que fue promovida por Zeneca, tuvo una amplia difusión, en España y en América Latina. AstraZeneca me propuso preparar esta 2ª edición del mismo modo abierto que en ocasión de la primera; su actual Director Médico Ramón Estiarte me ha ayudado en la selección de términos para el Glosario. A él y al anterior Director Médico de Zeneca, Manuel Martín, agradezco su idea inicial, su estímulo y ayuda, y las facilidades que han dado para la difusión de este libro. Joan-Ramon Laporte.

Elective mathematics has been an extra mathematics subject for pilot students of Eduardo Barretto Sr. National High School for quite some time now. Through this, many alumni testified how this helped them understand senior high school and college math. However, the teachers have also been struggling with the resources for specific areas of mathematics, such as Business Math, Statistics, Analytic Geometry, Trigonometry, and Calculus. When the pandemic hit the Philippines, contextualized learning material aligned with the Most Essential Learning Competencies (MELC) (...) helped elective mathematics teachers. The contextualized learning material was developed from April to August 2020 and was first validated in February 2021 by the students who participated in the pilot testing. However, following the due process, it was suggested that I revalidate the IDEA-formatted Analytic Geometry and Trigonometry instructional material. It examines Eduardo Barretto Sr. National High School mathematics teachers and SDO Calamba City experts' evaluation of the content's topics, objectives, concepts, directions, and activities and the format's prints, illustrations, design, and layout. Participants' perceptions of learning material were assessed using a 4-point Likert Scale survey. Hence, descriptive quantitative design. Participants were surveyed using a 4-point Likert Scale to assess their learning content impression. The findings reveal that the participants found the format and content of the developed learning material to be very satisfactory. The indicators "localized" and "can be done independently" were viewed as Fair and Satisfactory, respectively. The learning material was enhanced by localizing the activities and giving directions that could facilitate self-learning. (shrink)

Although the map of technology ethics is expanding, the growing subdomains within it may raise misgivings. In a recent and very interesting article, Sætra and Danaher have argued that the current dynamic of sub-specialization is harmful to the ethics of technology. In this commentary, we offer three reasons to diminish their concern about ethical proliferation. We argue first that the problem of demarcation is weakened if we attend to other sub-disciplines of technology ethics not mentioned by these authors. We claim (...) secondly that the logic of sub-specializations is less problematic if one does adopt mixed models (combining internalist and externalist approaches) in applied ethics. We finally reject that clarity and distinction are necessary conditions for defining sub-fields within ethics of technology, defending the porosity and constructive nature of ethical disciplines.

Dos filósofos dialogan sobre cómo definir en nuestros días la barbarie desde la filosofía política actual. Barajan para ello tres tipos de respuestas. La respuesta ilustrada es la que considera que la diversidad de concepciones del bien de nuestras sociedades es un hecho pernicioso para el desarrollo de la Humanidad, y que hay que imponer sobre ese batiburrillo de opiniones bárbaras la concepción sobre lo bueno más racional, la que en Occidente se propugna desde la Ilustración dieciochesca. La respuesta liberal, (...) por el contrario, acepta gustosa la pluralidad de concepciones morales y metafísicas de nuestras sociedades, y lo único que propone es evitar la barbarie haciendo que, en las cuestiones sobre cómo organizar nuestra sociedad, estas diferencias queden de lado y se intente encontrar un mínimo acuerdo entre todos. Por último, la respuesta postmetafísica sugiere aceptar que las cosmovisiones sobre el bien y el mundo no pueden quedar tan totalmente aparte de nuestros modos de organizar la sociedad como quiere el liberal; pero para evitar el conflicto bárbarico entre ellas, persigue hacer plausible sobre las demás una concepción concreta, que, a diferencia de la del ilustrado, aspiraría mucho más modestamente a sólo expandir un escepticismo para con el resto de nuestras propias creencias; autoironía que nos abriría al diálogo con las creencias de los demás y evitaría en ese juego de conversaciones la violencia de la imposición bárbara.

The term ‘intelligence’ as used in this paper refers to items of knowledge collected for the sake of assessing and maintaining national security. The intelligence community (IC) of the United States (US) is a community of organizations that collaborate in collecting and processing intelligence for the US. The IC relies on human-machine-based analytic strategies that 1) access and integrate vast amounts of information from disparate sources, 2) continuously process this information, so that, 3) a maximally comprehensive understanding of world actors (...) and their behaviors can be developed and updated. Herein we describe an approach to utilizing outcomes-based learning (OBL) to support these efforts that is based on an ontology of the cognitive processes performed by intelligence analysts. Of particular importance to the Cognitive Process Ontology is the class Representation that is Warranted. Such a representation is descriptive in nature and deserving of trust in its veridicality. The latter is because a Representation that is Warranted is always produced by a process that was vetted (or successfully designed) to reliably produce veridical representations. As such, Representations that are Warranted are what in other contexts we might refer to as ‘items of knowledge’. (shrink)

This paper describes an AFOSR-supported basic research program that focuses on developing a new framework for combining hard with soft data in order to improve space situational awareness. The goal is to provide, in an automatic and near real-time fashion, a ranking of possible threats to blue assets (assets trying to be protected) from red assets (assets with hostile intentions). The approach is based on Conceptual Spaces models, which combine features from traditional associative and symbolic cognitive models. While Conceptual Spaces (...) are revolutionary, they lack an underlying mathematical framework. Several such frameworks have attempted to represent Conceptual Spaces, but by far the most robust is the model developed by Holender. His model utilizes integer linear programming in order to obtain an overall similarity value between observations and concepts that support the formation of hypotheses. This paper will describe a method for building Conceptual Spaces models for threats that utilizes ontologies as a means to provide a clear semantic foundation for this inferencing process; in particular threat ontologies and space domain ontologies are developed and employed in this approach. A space situational awareness use-case is presented involving a kinetic kill scenario and results are shown to assess the performance of this fusion-based inferencing framework. (shrink)

This paper provides a method for characterizing space events using the framework of conceptual spaces. We focus specifically on estimating and ranking the likelihood of collisions between space objects. The objective is to design an approach for anticipatory decision support for space operators who can take preventive actions on the basis of assessments of relative risk. To make this possible our approach draws on the fusion of both hard and soft data within a single decision support framework. Contextual data is (...) also taken into account, for example data about space weather effects, by drawing on the Space Domain Ontologies, a large system of ontologies designed to support all aspects of space situational awareness. The framework is coupled with a mathematical programming scheme that frames a mathematically optimal approach for decision support, providing a quantitative basis for ranking potential for collision across multiple satellite pairs. The goal is to provide the broadest possible information foundation for critical assessments of collision likelihood. (shrink)

This study aims to find out the factors that hinder students in learning Integrated Art Education. A descriptive research design was utilized in the conduct of the study. The researcher prepared a questionnaire with 15 closed-ended- questions that could be answered objectively.

Interests in a subject also matter, the more you are interested in a particular subject, the more you will learn (...) the material. Parent support marks an impact on the student's interest in learning Arts. Therefore, personal interest in a subject must be given attention and managed properly. Parent's support also plays a vital role in reinforcing the students on what to pursue in order to maintain their motivation. (shrink)

Casgevy, the world’s first approved CRISPR-based cell therapy, has been priced at $2.2 million per patient. Although this hefty price tag was widely anticipated, the extremely high cost of this and other cell and gene therapies poses a major ethical issue in terms of equitable access and global health. In this Perspective, we argue that lowering the prices of future CRISPR therapies is an urgent ethical imperative. Although we focus on Casgevy as a case study, much of our analysis can (...) be extrapolated to the controversies over affordable access to other gene and cell therapies. First, we explain why this first-of-its-kind CRISPR therapy might be so expensive. We then analyze the ethical issues of equity and global health of early CRISPR treatments. Next, we discuss potential solutions to lower the prices of CRISPR gene therapies. We conclude that the approval of CRISPR transforms our obligations of justice and compels us to bring future gene therapies to the maximum possible number of patients with serious genetic diseases at affordable prices.

As we look beyond our terrestrial boundary to a multi-planetary future for humankind, it becomes paramount to anticipate the challenges of various human factors on the most likely scenario for this future: permanent human settlement of Mars. Even if technical hurdles are circumvented to provide adequate resources for basic physiological and psychological needs, Homo sapiens will not survive on an alien planet if a dysfunctional psyche prohibits the utilization of these resources. No matter how far we soar into the stars, (...) our psychologies for future generations will be forever tethered to the totality of our surroundings. By shaping our environment toward survival and welfare during the voyage to Mars and in a Martian colony, we indirectly shape our psyches and prepare them for a mission of unprecedented alienation and duration. Once on Mars, human factors such as leadership structure, social organization and code of conduct, group size, gender balance, developmental cycle, mobility, length of stay and the ecological settings and type and manner of subsistence, will create a novel Martian culture. The degree that settlers are severed from the Earth will affect how radically foreign this culture will be when compared with cultures on Earth. (shrink)

The study of belief is expanding and involves a growing set of disciplines and research areas. These research programs attempt to shed light on the process of believing, understood as a central human cognitive function. Computational systems and, in particular, what we commonly understand as Artificial Intelligence (AI), can provide some insights on how beliefs work as either a linear process or as a complex system. However, the computational approach has undergone some scrutiny, in particular about the differences between what (...) is distinctively human and what can be inferred from AI systems. The present article investigates to what extent recent developments in AI provide new elements to the debate and clarify the process of belief acquisition, consolidation, and recalibration. The article analyses and debates current issues and topics of investigation such as: different models to understand belief, the exploration of belief in an automated reasoning environment, the case of religious beliefs, and future directions of research.

Previous work has shown that the Complex Conceptual Spaces − Single Observation Mathematical framework is a useful tool for event characterization. This mathematical framework is developed on the basis of Conceptual Spaces and uses integer linear programming to find the needed similarity values. The work of this paper is focused primarily on space event characterization. In particular, the focus is on the ranking of threats for malicious space events such as a kinetic kill. To make the Conceptual Spaces framework work, (...) the similarity values between the contents of observations on the one hand and the properties of the entities observed on the other needs to be found. This paper shows how to exploit Dempster-Shafer theory to implement a statistical approach for finding these similarities values. This approach will allow a user to identify the uncertainty involved in similarity value data, which can later be propagated through the developed mathematical model in order for the user to know the overall uncertainty in the observation-to-concept mappings needed for space event characterization.

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

Amidst the challenges that teachers are facing nowadays, teachers resiliency in this new tough learning environment seemed to be an unexplored area. Thus, it is crucial to conduct studies that would explore factors that increase teachers resiliency particularly amidst teachers work-related stress and emotional exhaustion. This study explores the moderating effect of social support to self- efficacy and stress management strategies toward teachers resiliency employing descriptive-correlational with moderation design. teachers resiliency. The respondents were one hundred one (101) public elementary school (...) teachers who are currently associated with the four (4) public elementary schools in San Francisco District for the school year 2022-2023 using online survey questionnaire as the main instrument in gathering the data. The findings revealed that both teachers self-efficacy and stress management strategies have a significant relationship in teachers resiliency. This suggests that teachers must also be persistent in strengthening their self-efficacy and developing their stress management strategies to sustain their resiliency. Results also showed that social support effectively moderates the relationship between self-efficacy and teachers resilience. At the same time, it indicated that the higher self-efficacy of teachers was associated with a lower level of social support. Likewise, social support effectively moderates the relationship between stress management strategies and teachers resilience. Results also indicated that the higher level of stress management strategies was associated with lower level of social support. Individuals in the workplace especially supervisors and co-workers must consider providing their colleagues especially those with lower level of self- efficacy and stress management strategies with the necessary social support that they need to be resilient.

The overall goal of the approach developed in this paper is to estimate the likelihood of a given kinetic kill scenario between hostile spacebased adversaries using the mathematical framework of Complex Conceptual Spaces Single Observation. Conceptual spaces are a cognitive model that provide a method for systematically and automatically mimicking human decision making. For accurate decisions to be made, the fusion of both hard and soft data into a single decision framework is required. This presents several challenges to this data (...) fusion framework. The first is the challenge involved in handling multiple complex terminologies, which is addressed by drawing on a set of Space Domain Ontologies. Another challenge is the complex combinatorics involved when considering all possible feature combinations. This can be mitigated by using integer linear programming optimization that is outlined by the Complex Conceptual Spaces Single Observation mathematical model framework. A third challenge is the complicated physics that is involved in a spacecraft collision that must be addressed to obtain a better understanding of threat assessment. Overcoming these various challenges allows for a quantitative ranking for the potential of a kinetic kill collision across multiple spacecraft pairs. In addition to overcoming these challenges this paper will break down threat assessment into four domains and identify a ranking of threat both for each individual domain and for the four domains combined. Simulation results are shown to verify the developed concepts. (shrink)

In pornography, standard modelling contracts often require a performer to surrender rights over their public image and sexual media in perpetuity and across mediums. Under these contracts, performers are unable to determine who accesses, for what duration, and under what conditions, their sexual media. As a result, pornography has been described by some performers as a “life sentence” - a phrase which, if true, violates some strong intuitions we share about the importance of autonomy in sexual activity. Using the framework (...) of “affirmative consent,” I argue that these contracts violate performers' rights to sexual autonomy, and ought therefore to be considered objectionable. Overall, I argue that the legal regimes we create have a strong impact on people’s lives, and more important than legislating individual outcomes, the type of infrastructure we build around people’s decisions has the potential to radically empower - or disempower - those engaged in sex work.

Animal technique has occupied a marginal position in reflections on technique, and in the philosophical literature there is no strict definition of it. However, it is of great importance to understand the limits and the distinctive features of our own technique. This work argues that it is possible to establish a solid definition of animal technique based on two definitions of human technique (prosthetic notion of technique and material culture) and one particular dimension of human tools (cognitive tools). This paper (...) takes a naturalistic approach that enables to review different study cases focused on animals’ capacity to make and use tools. (shrink)

We examine the notion of cognitive artifact and its possible application to the animal technic. Although the issue of animal technic is not very much discussed, the case studies focused on the capacity of using and manufacturing tools suggest that some animals deploy cognitive skills. Could the tools employed by animals be considered genuine cases of cognitive artifacts? In this paper we propose a definition of “cognitive artifact” based on the notion of “proper function,” which allows us to develop a (...) gradual scale where we place different kinds of artifacts according to the prevalence of the cognitive function (in opposition to the prac-tical one). Applying this scale to the non-human sphere, we defend the idea that there exists a range of non-human technical phenomena of use and artifacts and tools manufacturing, and that some of this artifacts have an incipient proper cognitive function. In order to defend these theses, we examine the examples of the cobwebs, the nests and the honeycombs. (shrink)

In this dissertation I offer a global and detailed reconstruction of the logic developed by Gottlob Frege throughout his career. Even though Frege's logic suffered profound modifications from his initial formulation in Begriffsschrift to its revised version in Grundgesetze, the significant differences between these two works have been rarely taken at face value. I not only argue that these differences exist, but I also explain how they should be understood in the light of the evolution of Frege's thought. First, I (...) suggest a new reconstruction of Begriffsschrift's logic, which amounts to a completely novel reading of its formal system—one that contradicts the core of modern historical studies. In particular, I defend that this logic is not—as it has been repeatedly said—a second-order logic and provide the following reasons. (1) The language is not properly a formal language. (2) In Begriffsschrift there is only one sort of quantification: quantification over arguments. (3) Begriffsschrift's logic does not have a semantics in the modern sense. Second, I offer an explanation of the reasons that drive the evolution of Frege's logic. The transition from Begriffsschrift to Grundgesetze has been seldom addressed and never fully explained. According to my historical analysis, the switch from Frege's position concerning logic in Begriffsschrift to his later conception—finally established in Grundgesetze—can be articulated through the adoption of the distinction between concept and object as the basic element of the formal system. This leads to a formalisation of the notion of concept, which in the end drives to Grundgesetze's notion of function. Finally, I put forward a global analysis of Grundgesetze's logic. In this work, Frege develops a formal system that resembles in many relevant ways a second-order one. I suggest a reconstruction of this formal system that allows us to compare it with Begriffsschrift's. In particular, I formulate precisely every rule of inference proposed by Frege and especially focus on the rules of substitution. Moreover, I reflect on several meta-logical results that can be drawn from this reconstruction. (shrink)

Who is feminism for? The question reverberates frightfully in feminist discourse. Despite decades of theorizing that the unified feminist subject is an impossibility (given differences in race, class, sexuality, etc.), the question remains all too relevant in praxis—much to the detriment of the movement as a whole. Or at least, so argues Éléonore Lépinard in her new book, Feminist Trouble: Intersectional Politics in Post-Secular Times.

I critically discuss Dale Jacquette’s Frege: A Philosophical Biography. First, I provide a short overview of Jacquette’s book. Second, I evaluate Jacquette’s interpretation of Frege’s three major works, Begriffsschrift, Grundlagen der Arithmetik and Grundgesetze der Arithmetik; and conclude that the author does not faithfully represent their content. Finally, I offer some technical and general remarks.

This study focused on the adaptability and attitude of Grade 6 students in the Modular Learning Approach. This study aims to create a comprehensive review of the adaptability and attitude of elementary students in the Modular Learning Approach Especially. It seeks to describe and analyze the following: the profile of the respondents in terms of sex and education of the parents; the adaptability of the respondents toward the relationship between the student's profile in terms of their sex and educational attainment (...) of parents; the attitude of the respondent's significant relationship between sex and educational attainment. The researcher used the quantitative survey questionnaires to gather data from 128 Grade 6 students in five Elementary Schools in Bongabon, Nueva Ecija who enrolled during the School Year 2020-2021. The study revealed that the respondent's demographic profile in sex has no significant relationship to their adaptability and attitude in the modular learning approach. Yet the parents' educational attainment of the respondents has a significant relationship to adaptability in terms of learning assistance and support in the modular learning approach. The results further signified that parents' educational attainment is a basis for adaptability in modular learning. -/- . (shrink)

El objetivo de este artículo es clarificar la noción de «vida auténtica» tal y como es descrita por Joan Roura-Parella en su última obra Tema y variaciones de la personalidad (1950). Por «vida auténtica» se entiende una vida autogobernada, que permite al individuo realizar su propia singularidad y, por tanto, preservar su autonomía y dignidad como persona. Una vida dominada por factores ajenos al propio individuo, sean cuales sean éstos, es una vida alienada, que no permite el desarrollo del (...) individuo en tanto la persona que es. Se señala la relevancia filosófica de la propuesta de Roura-Parella, que es la de ofrecer una justificación no-evidencial para una forma de vida cristiana, agapística. De acuerdo con Roura-Parella, una forma de vida basada en la entrega amorosa para con el prójimo está justificada en tanto que ésta es el resultado último de nuestra propia condición natural, constituyendo así un acto de afirmación personal y siendo, por tanto, condición necesaria para gozar de una vida auténtica — «la vida alcanza su hondo sentido al salirse de sí misma para darse a los demás» (Roura-Parella, Tema y variaciones de la personalidad, 1950, p. 229). Se señalan las diferencias y semejanzas de la propuesta de Roura-Parella con respecto a las de Miguel de Unamuno y Joaquim Xirau, autores que fueron cercanos a Roura-Parella y quienes, aunque partiendo de razonamientos distintos a los de Roura-Parella, también concibieron la entrega amorosa para con el prójimo como un acto de afirmación personal.

La ciudadanía y lo político. Ciudadanía y crisis de la democracia liberal en un mundo en transformación es un texto provocador, que desafía directamente a las esferas de poder económico, político y social en el marco de la corrupción. Deja al descubierto las entrañas cancerígenas de una política enferma de poder, donde priman los intereses particulares o políticos sobre los intereses del pueblo. El libro es una lanza que atraviesa las profundidades que erosionan nuestra sociedad, realizando así un análisis riguroso (...) desde distintas aristas, que tienen un elemento común: la corrupción política. A lo largo de las páginas se ofrece un enorme panorama sobre el papel de la ciudadanía dentro de la sociedad, que reclama a gritos una revolución desalienante frente a la cleptoestructura. Es así como, el papel de la ciudadanía es el centro de la reflexión analítica que nos presenta Joan Lara Amat y León. (shrink)

When the cluster on “Sexual Expressions” began to take shape, one of the first people I thought of to serve as a referee was Joan Mason-Grant, given her longstanding philosophical and activist interest in pornography. It was with great sorrow that I learned, when I contacted her, that she had been diagnosed with a fast moving cancer. Joan was most interested to hear about this emerging “found cluster”; “it sounds like an interesting issue of Hypatia to look forward (...) to, but unfortunately my own academic work has had to be suspended” (May 17, 2009). She died just four days later. (shrink)

In 1937 Joan Robinson proposed that “when capitalism is rightly understood, the rate of interest will be set at zero and the major evils of capitalism will disappear”. A permanent zero rate would abolish capitalist profit except in limited cases, leaving nearly all output to be claimed by labour as wages. It would allow capital to be allocated on the basis of prospective social benefit rather than short-term profitability and a collateral basis that favours the wealthy. It would remove (...) some of the economic pressure to use resources unsustainably. So why not do this? I argue that the few available philosophical arguments for positive interest rates are unsatisfactory. Those who want a just and sustainable form of capitalism should target net zero for the interest rate. (shrink)

Bertrand Russell was never to forget the course he gave in Barcelona in the spring of 1920. In the bitter title-page of An Inquiry into Meaning and Truth (1940), after the legal ruling which had suspended him from teaching at City College, New York, he expressly mentions his lectures in Barcelona, along with those he had given at the Universities of Uppsala and Copenhagen and at the Sorbonne. He also alludes briefly to them in his Autobiography (Russell 1990, II, 143), (...) but their circumstances and import have received no attention to date. The aim of this paper is to bring to light the available information on this subject in the Russell Archives (McMaster University, Canada) and the papers left by Joan Crexells (1896-1926) and Eugenio d'Ors (1881-1954), the two Catalan philosophers behind Russell's visit, and to put forward an assessment of Russell's influence on Spanish philosophy.

Dance, as a mode of physical interaction, offers opportunities to care and be cared for, but this does not mean that dancers will, in fact, care. There may be no moral motivation underlying a lift, dip or intricate sequence of coordinated action. Choreographic scores may (knowingly or not) encourage merely perfunctory movements that are a poor simulacrum to care. Moreover, the caring that is expressed through dance need not transfer to other walks of life. I am not alone in knowing (...) spectacularly talented dancers whose behaviour off the dance floor is far from ethical – from the arrogant and petty to the flagrant abuse that plagues institutions of art and culture. This article considers how dance can illuminate both the acts and sentiments of care, conveying particular ethical orientations that trouble straightforward, absolute moral reasoning. The article frames an enquiry into the relation between ethics and aesthetics of care, drawn from feminist epistemologists Joan Tronto, Maurice Hamington, and Nel Noddings, as well as my own performance research on partnering. I frame a zone between technique and competence, foregrounding care in dance as both a technical and ethical issue. I will consider the necessary conditions by which dancing together can manifest care, rather than suggest blanketly that it always does or even that it should. To make this argument, I will describe and analyse Considered Care, a duet I created in the autumn of 2021 in collaboration with Boston Ballet. This performance research project provided the material from which to consider the concept of need, a condition of care in a dancing situation. I will conclude by considering the relationship between needs and trust in conceptualizing care within partnering. (shrink)

Among issues considered in contemporary ethics, apart from concepts such as good, value and justice, there is also the concept of care, discussed extensively in feminism. The article presents and analyses this ethical concept. It shows some problems with the translation of the English word ‘care’ into the Polish equivalent ‘troska’. The focus here, however, is mainly on the way of understanding the concept of care among feminist ethicists, such as Virginia Held, Nel Noddings, Joan Tronto, Diemut Bubeck, and (...) Sara Ruddick. For all of them, care is a relation, though they differ in their account of the specificity and meaning of this relation. (shrink)

From Joan Lindsay and cinematic master Peter Weir to Ted Kotcheff and Warwick Thornton, over past decades authors, screenwriters and filmmakers have produced films that depict the vast Australian landscape—simply referred to as terra nullius during colonial times by settlers literally confronting a continent vastly different from anything they were culturally and geographically accustomed to—as mysterious, impenetrable and ominous. Just like the dark cold of Scandinavia lends itself perfectly to contemporary Nordic Noir, the Australian New Wave or Australian Film (...) Revival of the 1970s and 1980s saw the release of films that encapsulated the eeriness of this largely rugged, arid and windswept continent, which opens up possibilities for anything to happen within those very, limitless, territories. This article analyses Weir’s Picnic at Hanging Rock (1975), Kotcheff’s horror flick par excellence Wake in Fright (1971); "the best and most terrifying film about Australia in existence" and with a TV-series remake in 2017, and Thornton’s more recent portrayal of Aboriginal misery and poverty Samson and Delilah (2009) set against a hostile urban backdrop, from a Foucauldian perspective. In its theoretical framework it also draws primarily on Freud. Heterotopia is used as a term to refer to strange, bewildering spaces that are disturbing and undecipherable—also described as “an unimaginable space, representable only in language, and as a kind of semimythical real site” (as articulated in Knight, 2017, 141). Foucault’s concept is applied in a cinematic context and used in conjunction with Freud’s notion of the uncanny as a feeling of uneasiness; or, as has been explained in his seminal text “The Uncanny” (1919), “that class of the terrifying that leads back to something long known to us, once very familiar.” We argue that these eerie, fear-induced screened narratives represent a nation whose weather-beaten, freedom-loving yet at heart anxiety-ridden people are most definitely a product of their environment.

Joan McGregor argues that “colleges and universities should adopt as part of their core mission the development of skills of civil discourse” rather than engaging in the practice of restricting controversial speakers from making presentations on campuses. I agree with McGregor concerning the need for increased civil discourse. However, this does not mean universities should welcome speakers to publicly present any material they wish without restriction or oversight. In this paper, I make three main arguments: (i) Colleges and universities (...) have a duty to protect members of the campus community from the harm and exclusion resulting from hateful or harmful speech, in the same way that they must protect them from sexual assaults and concussions. (ii) In the vast majority of cases, this duty can be fulfilled by holding speakers to standards of discourse that prevail in academic debate, and insisting on a number of procedural requirements. (iii) We should be wary of conservative arguments framed in terms of free speech, because they can be deployed to undermine important functions of the university in a democratic society, namely, to teach students how to be discerning citizens, and to protect thinkers willing to be critical of the government and the ruling classes.

William Faulkner (1897-1962), one of the United States’ most renowned authors, was born on Sept. 25, 1897, in New Albany, Mississippi. He initially focused on poetry, culminating in his first publication: The Marble Faun (1924). Subsequently, he transitioned to prose, producing novels such as The Sound and the Fury (1929), As I lay Dying (1930), Light in August (1932) and Absalom, Absalom! (1936), which are considered his most significant works. Like most of his oeuvre, these novels are set in a (...) fictional Southern region that Faulkner termed ‘Yoknapatawpha county.’ Nearly all works set in this fictional county are characterized by themes of race, incest, the American Civil War, and the decline of the antebellum South. Faulkner frequently employs diverse perspectives and techniques that directly represent the consciousness of his characters. Recognition for his literary achievements came relatively late in his career. The primary catalyst for this recognition was the Nobel Prize for Literature awarded to him in 1949, when he had arguably passed the zenith of his writing career. Faulkner’s extensive oeuvre, which spans from 1924 to 1962, also encompasses lesser-known works, such as Sanctuary (1931) and Intruder in the Dust (1948). In addition to novels, Faulkner authored numerous short stories that are considered among the finest in American literature. These include the story translated here, “Barn Burningr” originally published in 1939, in the June issue of Harper’s magazine. Faulkner died July 6 in Byhalia, Mississippi, of a heart attack. -/- In Dutch: William Faulkner (1897-1962) …, een van de beroemdste schrijvers uit de Verenigde Staten, werd geboren op 25 september 1897 in New Albany, Mississippi. Hij begon aanvankelijk met het schrijven van poëzie, wat resulteerde in zijn eerste publicatie: The Marble Faun (1924). Kort daarna liet hij poëzie voor wat het was en stortte hij zich op het proza. Dit leidde tot romans als The Sound and the Fury (1929), As I lay Dying (1930), Light in August (1932) en Absalom, Absalom! (1936) die als zijn belangrijkste werken worden beschouwd. Net als het merendeel van zijn oeuvre spelen deze romans zich af in een fictioneel Zuiden dat door Faulkner ‘Yoknapatawpha county’ genoemd werd. Vrijwel alle werken die zich in deze fictieve streek afspelen, worden gekenmerkt door thema’s als ras, incest, de Amerikaanse burgeroorlog en de teloorgang van het oude Zuiden. Faulkner maakt vaak gebruik van verschillende perspectieven en technieken die direct het bewustzijn van zijn personages representeren. Pas relatief laat in zijn carrière kreeg hij erkenning voor zijn literaire verdiensten. De belangrijkste stimulans hiervoor was de Nobelprijs voor de literatuur die hem werd toegekend in 1949, toen hij als schrijver eigenlijk al over zijn toppunt heen was. Faulkners omvangrijke oeuvre, dat ontstond in de periode van 1924 tot 1962, omvat ook minder bekende werken, zoals Sanctuary (1931) en Intruder in the Dust (1948). Naast romans schreef Faulkner echter ook nog een groot aantal korte verhalen die tot de absolute top van het Amerikaanse verhaal gerekend worden. Daartoe behoort ook het hier vertaalde verhaal ‘In vlammen op’ (‘Barn Burning’), dat oorspronkelijk werd gepubliceerd in 1939, in het juninummer van het tijdschrift Harper’s. Faulkner stierf op 6 juli in Byhalia, Mississippi, aan een hartaanval. -/- . (shrink)

This paper presents and discusses design studio outcomes developed in response to a studio brief linked to the Fun Palace Futures initiative of the Royal British Institute of British Architects (RIBA) in honour of architect Cedric Price and artist Joan Littlewood. The studio brief was collaboratively developed by the authors. Its core question was: How could the thoughts that guided the development and design of the Fun Palace – a project that was never built but is still today cited (...) as a model for thinking flexible and open architecture – be re-interpreted and renewed for the future? This line of thinking guided the initial and experimental research phase, during which students developed an understanding of what indeterminacy is or could be. The paper shows that through the translation of some of the essential principles of the Fun Palace project into pedagogical instruments, students were enabled to approach the questions of indeterminacy in an open and innovative manner. The paper argues that the use of a variety of media, which often went far beyond the conventional architectural pallet, and the introduction of media shifts were crucial in assisting the students in developing their own tools for creating a new kind of open and flexible architecture. The paper presents this pedagogic approach. We show that the conditions of indeterminacy, uncertainty, chance and change, hold potential for framing the design and creation of a new kind of dynamic architecture, and for initiating experimental architectural thinking in a design studio setting.

In my paper I make a summary assessment of the connection between Eugeni Crexells and Eugeni d'Ors and that of both of them with pragmatism. I organize it in three sections: 1. First, the philosophical formation of Crexells and its relation with D'Ors; 2. Eugeni d'Ors and pragmatism, and 3. Joan Crexells and pragmatism.
