The present collection of essays aims at casting light on important elements of Wittgenstein's thought and intellectual development. Some of Wittgenstein's ideas are here discussed using the «Tractatus» as a frame of reference, others by relating them to the views of G. Frege, G.E.M. Anscombe and D. Davidson.

This edited collection casts light on central issues within contemporary philosophy of mathematics such as the realism/anti-realism dispute; the relationship between logic and metaphysics; and the question of whether mathematics is a science of objects or structures. The discussions offered in the papers involve an in-depth investigation of, among other things, the notions of mathematical truth, proof, and grounding; and, often, a special emphasis is placed on considerations relating to mathematical practice. A distinguishing feature of the book is the multicultural (...) nature of the community that has produced it. Philosophers, logicians, and mathematicians have all contributed high-quality articles which will prove valuable to researchers and students alike. (shrink)

BackgroundCaregivers may play a fundamental role in the clinical pathway of cancer patients. They provide emotional, informational, and functional support as well as practical assistance, and they might help mediate the interaction and communication with the oncologists when care options are discussed, or decisions are made. Little is known about the impact of dyadic dynamics on patient-doctor communication, patient's satisfaction, or adherence to the therapies. This study protocol aims to evaluate the efficacy of a psychological support intervention on patients-caregivers relationship (...) and their alignment in the treatment decision-making process and estimate related improvement in patient' compliance/adherence to treatments.MethodsA total of 102 patients-caregivers' dyads will be involved, among breast and prostate cancer patients. The study entails a pre- post- evaluation through psychological questionnaires, with a randomization of participants in two conditions, the experimental one in which subjects participate in a psychological support consultation, and the control one, where dyads do not receive any intervention. A follow up after 6 months from the enrollment is planned.DiscussionA positive impact of the psychological support intervention on patients' anxiety, depression, distress, and perceived social support is expected. Such improvements can directly affect patients' satisfaction and adherence to treatments. Data gathered from this study may inform health care providers, policy makers, and public health managers about the importance of caregiver's involvement in the cancer care pathway, and the best way to manage it. A further impact is to develop a specific intervention protocol to support caregivers' involvement in cancer care pathway, improve patient's wellbeing, the interaction with physicians and the compliance with the cancer treatment.

Reasoning with diagrams is considered to be a peculiar form of reasoning. Diagrams are often associated with imagistic representations conveyed by spatial arrangements of lines, points, figures, or letters that can be manipulated to obtain knowledge on a subject matter. Reasoning with diagrams is not just ‘peculiar’ because reasoners use spatially arranged characters to obtain knowledge – diagrams apparently have cognitive surplus: they enable a quasi-intuitive form of knowledge. The present paper analyses the issue of diagrams’ cognitive value by enquiring (...) into the tradition of symbolic cognition developed by Leibniz, Lambert, and Kant. The proposal resulting from this enquiry is to question the idea that the cognitive value of diagrams lies solely in allowing evidence for inferences. The imaginative dimension of diagrams connects reasoning to doxastic attitudes of meditation and enquiry. (shrink)

Vardanyan’s Theorems [36, 37] state that $\mathsf {QPL}(\mathsf {PA})$ —the quantified provability logic of Peano Arithmetic—is $\Pi ^0_2$ complete, and in particular that this already holds when the language is restricted to a single unary predicate. Moreover, Visser and de Jonge [38] generalized this result to conclude that it is impossible to computably axiomatize the quantified provability logic of a wide class of theories. However, the proof of this fact cannot be performed in a strictly positive signature. The system $\mathsf (...) {QRC_1}$ was previously introduced by the authors [1] as a candidate first-order provability logic. Here we generalize the previously available Kripke soundness and completeness proofs, obtaining constant domain completeness. Then we show that $\mathsf {QRC_1}$ is indeed complete with respect to arithmetical semantics. This is achieved via a Solovay-type construction applied to constant domain Kripke models. As corollaries, we see that $\mathsf {QRC_1}$ is the strictly positive fragment of $\mathsf {QGL}$ and a fragment of $\mathsf {QPL}(\mathsf {PA})$. (shrink)

Drawing from Goffman’s original observations on stigma and the consequences of interactions between the stigmatized and supportive or stigmatizing audiences, we conduct a 20-year review of the diverse literature on stigma to revisit the collective nature of stigmatization processes. We find that studies on stigma’s origins, responses, processes, and outcomes have diverged from Goffman’s relational view of stigma as they have overlooked important relational mechanisms explaining the processes of (de)stigmatization. We draw from those conclusions to justify the need to study (...) stigma as a collective phenomenon. We develop a relational perspective on stigma based on understanding how attributes are stigmatized (or not) by audiences in their interactions. We argue that to advance stigma research, it is necessary to build on Goffman’s theory to include the stigmatizers (i.e., the normal) and supporters (i.e., the wise); how they create, sustain, or remove stigma; and how they relate to the stigmatized (i.e., the targets). Accordingly, we provide a research agenda on stigma as a collective phenomenon that theorizes a relational perspective, proposes a typology of how audiences relate to stigmatization, and identifies patterns of relations between audiences. We thus offer a missing piece to existing accounts of stigma by focusing on the key role of audiences (i.e., stigmatizers or supporters of the stigmatized) rather than on the targets of stigma (i.e., the own).

In 2020, the European Union announced the award of the contract for the biometric part of the new database for border control, the Entry Exit System, to two companies: IDEMIA and Sopra Steria. Both companies had been previously involved in the development of databases for border and migration management. While there has been a growing amount of publicly available documents that show what kind of technologies are being implemented, for how much money, and by whom, there has been limited engagement (...) with digital methods in this field. Moreover, critical border and security scholarship has largely focused on qualitative and ethnographic methods. Building on a data feminist approach, we propose a transdisciplinary methodology that goes beyond binaries of qualitative/quantitative and opacity/transparency, examines power asymmetries and makes the labour of coding visible. Empirically, we build and analyse a dataset of the contracts awarded by two European Union agencies key to its border management policies – the European Agency for Large-Scale Information Systems (eu-LISA) and the European Border and Coast Guard Agency (Frontex). We supplement the digital analysis and visualisation of networks of companies with close reading of tender documents. In so doing, we show how a transdisciplinary methodology can be a device for making datafication ‘intelligible’ at the European Union borders. (shrink)

Este artículo1 explora dos obras cinematográficas guatemaltecas, Polvo (2012) y Nuestras madres (2019), dirigidas por Julio Hernández Cordón y César Díaz correspondientemente. En ambos largometrajes la denuncia sobre la violación de derechos humanos durante el pasado conflicto armado guatemalteco, la búsqueda de padres o familiares desaparecidos y sus secuelas en las víctimas constituyen la temática central. Por tanto, el análisis se centra en la importancia que tiene la búsqueda del padre desaparecido en los hijos, quienes, a raíz de esta vivencia (...) traumática, experimentan un vacío identitario, así como estragos individuales provocados por la falta de la figura paterna. Por otro lado, también se analizan el trauma y el silencio de las madres sobrevivientes como remanente del miedo/terror experimentado durante el conflicto armado, pero también como un mecanismo de protección para sus hijos. En especial, el análisis se auxilia teóricamente con el extenso trabajo realizado por el sociólogo uruguayo Gabriel Gatti sobre la desaparición forzada. 1 Este ensayo forma parte de una serie de proyectos de investigación y se realizó con el apoyo de la beca Volgenau de la Academia Naval de Estados Unidos.

Fencing for the blind and visually impaired is an emerging sub-discipline of fencing that creates unusual conditions for meaning-making through interaction between embodied endowments and worldly affordances. With the rules of fencing slightly adjusted to the needs of the blindfolded participants – regardless of their sightedness – the discipline requires the fencers to engage in a duel by relying on other than visual cues. This article explores what an autoethnographic account of experiences of participation in fencing for the blind and (...) visually impaired brings to debates on the embodied, and specifically sensory difference. The discussion of these experiences intersects with debates on affect, affordance, and habit, with all three having important roles in related semiotic processes. Presented vignettes draw upon the author’s lived experiences of participation in fencing for the blind and visually impaired and are analyzed as part of a mixed-method autoethnographic study, accompanied by sensory methodologies, with a focus on an inquiry beyond the visual. The vignettes elucidate how we make sense of our surroundings through a complex engagement with the ecology of sensory and affective processes. In addition to exploring the role of affective and pre-conceptual aspects of our experiences, the article seeks to understand how semiosis occurs through both exposure to as well as the active pursuit of specific environmental signs available to us. The article also derives from biosemiotics to examine the complex relationship between meaning-making processes and habits. Finally, the autoethnographic account provides an insight into how we habituate the world and our embodied differences and thus enable meaning-making processes. (shrink)

This paper investigates the interpretation of counterfactual conditionals. The main goal of the paper is to provide an account of the semantic role of similarity in the evaluation of counterfactuals. The paper proposes an analysis according to which counterfactuals are treated as predications “ de re ” over past situations in the actual world. The relevant situations enter semantic composition via the interpretation of tense. Counterfactuals are treated as law-like conditionals with de re predication over particular facts. Similarity with respect (...) to particular facts is ensured by the semantics of tense in interaction with the modal, while the modal itself is responsible for invoking laws. In the paper, various arguments are provided to support a local view of similarity over the global approach found in semantics along the line of Lewis’s and Stalnaker’s. Arguments are also provided tying the evaluation of similarity to the interpretation of tense. Finally, arguments are provided to show that in key cases, the approaches make comparable predictions.

This paper attempts to show that mathematical knowledge does not grow by a simple process of accumulation and that it is possible to provide a quasi-empirical (in Lakatos's sense) account of mathematical theories. Arguments supporting the first thesis are based on the study of the changes occurred within Eudidean geometry from the time of Euclid to that of Hilbert; whereas those in favour of the second arise from reflections on the criteria for refutation of mathematical theories.

The present article aims at showing that it is possible to construct a realist philosophy of mathematics which commits one neither to dream the dreams of Platonism nor to reduce the word ''realism'' to mere noise. It is argued that mathematics is a science of patterns, where patterns are not objects (or properties of objects), but aspects, or aspects of aspects, etc. of objects. (The notion of aspect originates from ideas sketched by Wittgenstein in the Philosophical Investigations.).

Mary Livermore'sMy Story of the Waris a valuable piece of travel writing written from the point of view of a nurse who documented her unexpected personal and professional journey to administer the Sanitary Commission of the United States Union Army and provide nursing care during the American Civil War. Although Livermore's pre‐war background had not been solely limited to the domestic sphere, her wartime experience involved a public negotiation between the traditional domestic realm assigned to women and new nursing professional (...) functions that emerged during the war. In a context in which the general access of women to public writing was rather limited and in which nursing was not a formally regulated professional activity, Livermore's triumphal narrative reflects the increasing connection between progressively professional nursing functions that emerged in the context of war and a new women's rights leadership forged during her autobiographical journey.

Cette étude vise à comprendre les spécificités sémantiques des lexèmes _manipuler_ et _modifier_ afin d’éclairer l’usage qui en est fait en bioéthique lorsque les actions désignées ont comme objet l’embryon, le cerveau, l’ADN, l’Homme, le vivant ou la procréation. En s’appuyant sur les définitions des dictionnaires et sur les réponses à un questionnaire soumis aux locuteurs, et en se servant de concepts de la sémantique combinatoire, de la sémantique argumentative, de la sémantique des cadres et de l’aspect sémantique, l’étude identifie (...) les éléments de signification propres à chacun des deux lexèmes. Ces éléments sont étroitement liés au potentiel de signification des lexèmes et aux traits aspectuels des procès qu’ils désignent. À l’issue de cette étude, un ensemble de traits sémantiques caractéristiques de chaque lexème est proposé, dans une perspective contrastive. (shrink)

The coronavirus disease 2019 pandemic had a negative psychological impact on the population at scale, yet it is possible that vulnerable patient populations may experience a heavier burden with increased feelings of anxiety and distress. Cancer patients have to trade-off between the fear of exposing themselves to the virus and the need to continue life-saving medical procedures. The present study investigated the prevalence of generalized anxiety and post-traumatic stress symptoms in a population of Italian cancer patients and healthy participants in (...) the months following the COVID-19 outbreak. Using standardized measures of PTSS and generalized anxiety, we found that patients experienced higher levels of adverse mental health outcomes. Several variables were found to negatively affect PTSS and anxiety in this population, including the younger age of respondents, having children, and the impossibility to attend regular medical check-ups. These findings stress the importance of maintaining a clear and regular communication with patients throughout future waves of the pandemic and ensure continuity of care in this vulnerable population. Furthermore, this study indicates the need to establish psychological interventions aimed at patients with cancer, targeting especially younger generations who are more likely to experience adverse psychological outcomes.

Margaret Archer plays a leading role in the sociological analysis of the relation between structure and agency, and particularly in the study of reflexivity. The main aim of this article is to discuss her approach, focusing on the main contributions and limitations of Archer’s theory of reflexivity. It is argued that even though her research is a pioneering one, proposing an operationalization of the concept of reflexivity in view of its empirical implementation, it also minimizes crucial social factors and the (...) dimensions necessary for a more complex and multi-dimensional study of the concept, such as social origins, family socialization, processes of internalization of exteriority, the role of other structure–agency mediation mechanisms and the persistence of social reproduction.

Spin is a fundamental and distinctive property of the electron, having far-reaching implications. Yet its purely formal treatment often blurs the physical content and meaning of the spin operator and associated observables. In this work we propose to advance in disclosing the meaning behind the formalism, by first recalling some basic facts about the one-particle spin operator. Consistently informed by and in line with the quantum formalism, we then proceed to analyse in detail the spin projection operator correlation function \=\left\langle (...) \left \left \right\rangle \) for the bipartite singlet state, and show it to be amenable to an unequivocal probabilistic reading. In particular, the calculation of \\) entails a partitioning of the probability space, which is dependent on the directions \.\) The derivation of the CHSH- or other Bell-type inequalities, on the other hand, does not consider such partitioning. This observation puts into question the applicability of Bell-type inequalities to the bipartite singlet spin state. (shrink)

We explore the distinctive characteristics of Mexico's society, politics and history that impacted the establishment of genetics in Mexico, as a new disciplinary field that began in the early 20th century and was consolidated and institutionalized in the second half. We identify about three stages in the institutionalization of genetics in Mexico. The first stage can be characterized by Edmundo Taboada, who was the leader of a research program initiated during the Cárdenas government (1934-1940), which was primarily directed towards improving (...) the condition of small Mexican farmers. Taboada is the first Mexican post-graduate investigator in phytotechnology and phytopathology, trained at Cornell University and the University of Minnesota, in 1932 and 1933, respectively. He was the first investigator to teach plant genetics at the National School of Agriculture and wrote the first textbook of general genetics, Genetics Notes, in 1938. Taboada's most important single genetics contribution was the production of "stabilized" corn varieties. The extensive exile of Spanish intellectuals to Mexico, after the end of Spain's Civil War (1936-1939), had a major influence in Mexican science and characterizes the second stage. The three main personalities contributing to Mexican genetics are Federico Bonet de Marco and Bibiano Fernández Osorio Tafall, at the National School of Biological Sciences, and José Luis de la Loma y Oteyza, at the Chapingo Agriculture School. The main contribution of the Spanish exiles to the introduction of genetics in Mexico concerned teaching. They introduced in several universities genetics as a distinctive discipline within the biology curriculum and wrote genetics text books and manuals. The third stage is identified with Alfonso León de Garay, who founded the Genetics and Radiobiology Program in 1960 within the National Commission of Nuclear Energy, which had been founded in 1956. The Genetics and Radiobiology Program rapidly became a disciplinary program, for it embraced research, teaching, and training of academics and technicians. The Mexican Genetics Society, created by de Garay in 1966, and the development of strains and cultures for genetics research were important activities. One of de Garay's key requirements was the compulsory training of the Program's scientists for at least one or two years in the best universities of the United States and Europe. De Garay's role in the development of Mexican genetics was fundamental. His broad vision encompassed the practice of genetics in all its manifestations. (shrink)

Prominent tuberculosis (TB) actors are invoking solidarity to motivate and justify collective action to address TB, including through intensified development and implementation (D&I) of technologies such as drugs and diagnostics. We characterize the ethical challenges associated with D&I of new TB technologies by drawing on stakeholder perspectives from 23 key informant interviews and we articulate the ethical implications of solidarity for TB technology D&I. The fundamental ethical issue facing TB technological D&I is a failure within and beyond the TB community (...) to stand in solidarity with persons with TB in addressing the complex sociopolitical contexts of technological D&I. The failure in solidarity relates to two further ethical challenges raised by respondents: skewed power dynamics that hinder D&I and uncertainties around weighing risks and benefits associated with new technologies. Respondents identified advocacy and participatory research practices as necessary to address such challenges and to motivate sustained collective action to accelerate toward TB elimination. We present the first empirical examination of bioethical accounts of solidarity in public and global health. Our study suggests that solidarity allows us better to understand and address the ethical challenges that arrest the D&I of new TB technologies. Solidarity lends credence to policies and practices that address the relational nature of illness and health through collective action. (shrink)

Online education has become an essential component of education. Thus, several factors, such as the student’s learning strategy and motivation, generally contribute to their academic success. This study investigates the relationship between learning strategies, motivation, and online learning environment among 150 first-year college students. Employing correlational design, the statistical findings of the study reveal that the r coefficient of 0.59 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision (...) to reject the null hypothesis. Hence, a significant relationship exists between learning strategies, motivation, and the online learning environment. (shrink)

The somatic mutation theory (SMT) of cancer has been and remains the prevalent theory attempting to explain how neoplasms arise and progress. This theory proposes that cancer is a clonal, cell‐based disease, and implicitly assumes that quiescence is the default state of cells in multicellular organisms. The SMT has not been rigorously tested, and several lines of evidence raise questions that are not addressed by this theory. Herein, we propose experimental strategies that may validate the SMT. We also call attention (...) to an alternative theory of carcinogenesis, the tissue organization field theory (TOFT), which posits that cancer is a tissue‐based disease and that proliferation is the default state of all cells. Based on epistemological and experimental evidence, we argue that the TOFT compellingly explains carcinogenesis, while placing it within an evolutionarily relevant context.magnified imagemagnified imageAna Soto and Carlos Sonnenschein are at Tufts University School of Medicine, Boston, MA, USA.

How do we acquire a mental representation of our own face? Recently, synchronous, but not asynchronous, interpersonal multisensory stimulation between one’s own and another person’s face has been used to evoke changes in self-identification . We investigated the conscious experience of these changes with principal component analyses that revealed that while the conscious experience during synchronous IMS focused on resemblance and similarity with the other’s face, during asynchronous IMS it focused on multisensory stimulation. Analyses of the identified common factor structure (...) revealed significant quantitative differences between synchronous and asynchronous IMS on self-identification and perceived similarity with the other’s face. Experiment 2 revealed that participants with lower interoceptive sensitivity experienced stronger enfacement illusion. Overall, self-identification and body-ownership rely on similar basic mechanisms of multisensory integration, but the effects of multisensory input on their experience are qualitatively different, possibly underlying the face’s unique role as a marker of selfhood.

Croatia is a transitional society in that it is a country emerging from a socialist command economy toward a market-based economy with ensuing structural changes of a social and political nature—some extending into the healthcare system. A legacy from our past is that, until now, Croatian healthcare institutions have had no real experience with clinical ethics support services. When clinical cases arise presenting complex ethical dilemmas in treatment options, the challenges presented to the medical team are substantial. The case described (...) below recently occurred on a ward in a university hospital in Croatia. An unexpected request from the patient’s parents created a number of issues that needed to be addressed by the medical team, which was made more difficult by the lack of clinical ethics support services. Such cases press the question currently being debated as to what type of ethics support services would be suitable for Croatia and why. (shrink)

The present paper aims at showing that there are times when set theoretical knowledge increases in a non-cumulative way. In other words, what we call ‘set theory’ is not one theory which grows by simple addition of a theorem after the other, but a finite sequence of theories T1, ..., Tn in which Ti+1, for 1 ≤ i < n, supersedes Ti. This thesis has a great philosophical significance because it implies that there is a sense in which mathematical theories, (...) like the theories belonging to the empirical sciences, are fallible and that, consequently, mathematical knowledge has a quasi-empirical nature. The way I have chosen to provide evidence in favour of the correctness of the main thesis of this article consists in arguing that Cantor–Zermelo set theory is a Lakatosian Mathematical Research Programme (MRP).

How can we feel at home in this world without clinging to false certainties? This book offers a humanist re-reading of philosophical pragmatism and explores its potentials for a worldview that relies only on human resources. Thinking along with authors like William James and F.C.S. Schiller, it highlights a fundamentally humanist strand of pragmatism aimed at fostering human creativity and transformative action. It is grounded in everyday experience and underlines our responsibility to strive for the better. Ana Honnacker traces perspectives (...) on science, religion, and ethics in the light of a pragmatic understanding of humanism. Furthermore, she suggests how to address the existential challenges we face today. Thus, pragmatic humanism is explored not only as a philosophy for critical minds, but also as a way of life.

Codes of medical ethics (codes) are part of a longstanding tradition in which physicians publicly state their core values and commitments to patients, peers, and the public. However, codes are not static. Using the historical evolution of the Canadian Medical Association's Code of Ethics as an illustrative case, we argue that codes are living, socio-historically situated documents that comprise a mix of prescriptive and aspirational content. Reflecting their socio-historical situation, we can expect the upheaval of the COVID-19 pandemic to prompt (...) calls to revise codes. Indeed, Alex John London has argued in favour of specific modifications to the World Medical Association's International Code of Medical Ethics (which has since been revised) in light of moral and scientific failures that occurred during the COVID-19 pandemic. Responding to London, we address the more general question: should codes be modified to reflect lessons drawn from the COVID-19 pandemic or future such upheavals? We caution that codes face limitations as instruments of policy change because they are inherently interpretive and ‘multivocal’, that is, they usually underdetermine or provide more than one answer to the question, ‘What should I do now?’ Nonetheless, as both prescriptive and aspirational documents, codes also serve as tools for reflection and deliberation—collective practices that are necessary to engaging with and addressing the moral and scientific uncertainties inherent to medicine.
