Cancer diagnosed during pregnancy is a rare event. The most common type of malignancy diagnosed in pregnant women is breast cancer, whose incidence is expected to raise in the next future due to delayed childbirth, as well as to the increased occurrence of the disease at young age. Pregnant women diagnosed with breast cancer are exposed to multiple sources of stress, which may lead to poorer obstetric outcomes, such as preterm birth and low birth weight. In addition, pregnancy involves physiological (...) changes in the breasts that may blur the signs of cancer, with delayed diagnosis and poor prognosis. However, the lived experience of these women was investigated in very few studies. Given this scenario, we conducted this qualitative study to describe and understand women’s subjective experience of being diagnosed with breast cancer during pregnancy. The study was conducted following the principles of Interpretative Phenomenological Analysis. Participants were five women with breast cancer diagnosed during pregnancy, purposefully recruited at a public hospital during medical visits and interviewed at treatment initiation. The interview transcripts were analyzed using thematic analysis. The textual analysis led to the identification of three main themes related to: the emotional storm experienced after cancer diagnosis, and the importance of receiving appropriate information and being focused on treatment decisions; physical changes and comparisons with healthy women, associated with feelings of sadness and inadequacy; being positive, feeling free to disclose all kinds of emotions, religion and spirituality as sources of strength. The paradoxical coexistence of pregnancy and cancer represents a stressful experience for women and their loved ones. Adopting a systemic perspective may be important to understand the effects of such a complex condition, also considering its impact on healthcare workers. (shrink)

The aim of this article is to investigate the roles of commutative diagrams (CDs) in a specific mathematical domain, and to unveil the reasons underlying their effectiveness as a mathematical notation; this will be done through a case study. It will be shown that CDs do not depict spatial relations, but represent mathematical structures. CDs will be interpreted as a hybrid notation that goes beyond the traditional bipartition of mathematical representations into diagrammatic and linguistic. It will be argued that one (...) of the reasons why CDs form a good notation is that they are highly mathematically tractable: experts can obtain valid results by ‘calculating’ with CDs. These calculations, take the form of ‘diagram chases’. In order to draw inferences, experts move algebraic elements around the diagrams. It will be argued that these diagrams are dynamic. It is thanks to their dynamicity that CDs can externalize the relevant reasoning and allow experts to draw conclusions directly by manipulating them. Lastly, it will be shown that CDs play essential roles in the context of proof as well as in other phases of the mathematical enterprise, such as discovery and conjecture formation. (shrink)

This paper confronts Zagzebski’s exemplarism with the intertwined debates over the conditions of exemplarity and the unity-disunity of the virtues, to show the advantages of a pluralistic exemplar-based approach to moral education (PEBAME). PEBAME is based on a prima facie disunitarist perspective in moral theory, which amounts to admitting both exemplarity in all respects and single-virtue exemplarity. First, we account for the advantages of PEBAME, and we show how two figures in recent Italian history (Giorgio Perlasca and Gino Bartali) satisfy (...) Blum’s definitions of ‘moral hero’ and ‘moral saint’ (1988). Then, we offer a comparative analysis of the effectiveness of heroes and saints with respect to character education, according to four criteria derived from PEBAME: admirability, virtuousness, transparency, and imitability. Finally, we conclude that both unitarist and disunitarist exemplars are fundamental to character education; this is because of the hero's superiority to the saint with respect to imitability, a fundamental feature of the exemplar for character education.

The aim of this article is to investigate specific aspects connected with visualization in the practice of a mathematical subfield: low-dimensional topology. Through a case study, it will be established that visualization can play an epistemic role. The background assumption is that the consideration of the actual practice of mathematics is relevant to address epistemological issues. It will be shown that in low-dimensional topology, justifications can be based on sequences of pictures. Three theses will be defended. First, the representations used (...) in the practice are an integral part of the mathematical reasoning. As a matter of fact, they convey in a material form the relevant transitions and thus allow experts to draw inferential connections. Second, in low-dimensional topology experts exploit a particular type of manipulative imagination which is connected to intuition of two- and three-dimensional space and motor agency. This imagination allows recognizing the transformations which connect different pictures in an argument. Third, the epistemic—and inferential—actions performed are permissible only within a specific practice: this form of reasoning is subject-matter dependent. Local criteria of validity are established to assure the soundness of representationally heterogeneous arguments in low-dimensional topology. (shrink)

The objective of this article is twofold. First, a methodological issue is addressed. It is pointed out that even if philosophers of mathematics have been recently more and more concerned with the practice of mathematics, there is still a need for a sharp definition of what the targets of a philosophy of mathematical practice should be. Three possible objects of inquiry are put forward: (1) the collective dimension of the practice of mathematics; (2) the cognitives capacities requested to the practitioners; (...) and (3) the specific forms of representation and notation shared and selected by the practitioners. Moreover, it is claimed that a broadening of the notion of ‘permissible action’ as introduced by Larvor (2012) with respect to mathematical arguments, allows for a consideration of all these three elements simultaneously. Second, a case from topology – the proof of Alexander’s theorem – is presented to illustrate a concrete analysis of a mathematical practice and to exemplify the proposed method. It is discussed that the attention to the three elements of the practice identified above brings to the emergence of philosophically relevant features in the practice of topology: the need for a revision in the definition of criteria of validity, the interest in tracking the operations that are performed on the notation, and the constant and fruitful back-and-forth from one representation to another in dealing with mathematical content. Finally, some suggestions for further research are given in the conclusions. (shrink)

The current “exemplarist turn” within virtue ethics is increasingly shedding light on the importance of exemplars both as enabling one to identify the virtues and for the importance they bear for orienting one’s conduct, as well as for educating the novice. However, even if categorizations of exemplars have already been proposed, there seems to be a lack of discussion on the kind of imitation different exemplars are supposed to elicit. In order to offer a preliminary answer to this question, in (...) this paper I present three paths to flourishing via imitation of exemplary individuals: The Platonic, the Stoic, and the Aristotelian. Then, I sketch an attempt to reconcile these models. In conclusion, I suggest that, when it comes to education, this reconciliation becomes necessary. Along these lines, I recommend that a multi-step educational program is elaborated. (shrink)

There is empirical evidence suggesting a positive link between direct experiences in nature and people’s environmental attitudes (EA) and behaviors (EB). This has led researchers to encourage more frequent contact with nature, especially during childhood, as a way of increasing pro-environmentalism (i.e., pro-EA and pro-EB). However, the association between experiences in nature and EA/EB is complex, and specific guidelines for people’s everyday contact with nature cannot be provided. This article offers an overview of the research conducted until know about the (...) relation between experiences in nature and pro-environmentalism, and opens up new inquiries for future research. We begin with an introduction to people’s current tendency toward an alienation from the natural world and set out the objectives of the article. It is followed by three main sections. The first one reports on what experiences in nature refer to, how and where they occur. The second section describes the different approaches used to investigate and interpret the experiences in nature-EA and EB relation. The last section provides suggestions for future research. We close by making some final remarks about the importance of (re)stablishing a greater interaction with nature for people’s pro-EA and EB. (shrink)

Schwichtenberg showed that the System T definable functionals are closed under a rule-like version Spector’s bar recursion of lowest type levels 0 and 1. More precisely, if the functional Y which controls the stopping condition of Spector’s bar recursor is T-definable, then the corresponding bar recursion of type levels 0 and 1 is already T-definable. Schwichtenberg’s original proof, however, relies on a detour through Tait’s infinitary terms and the correspondence between ordinal recursion for α < ε₀ and primitive recursion over (...) finite types. This detour makes it hard to calculate on given concrete system T input, what the corresponding system T output would look like. In this paper we present an alternative (more direct) proof based on an explicit construction which we prove correct via a suitably defined logical relation. We show through an example how this gives a straightforward mechanism for converting bar recursive definitions into T-definitions under the conditions of Schwichtenberg’s theorem. Finally, with the explicit construction we can also easily state a sharper result: if Y is in the fragment Tᵢ then terms built from BR^ℕ,σ for this particular Y are definable in the fragment T_i+max{1,level(σ)}+2.

In this paper we develop the notion of formal precover in a topos by defining a relation between elements and sets in a local set theory. We show that such relations are equivalent to modalities and to universal closure operators. Finally we prove that these relations are well characterized by a convenient restriction to a particular set.

This article sheds light on moral education from an exemplarist perspective. Following Linda Zagzebski's Exemplarist Virtue Theory, we relate several fundamental exemplarist intuitions to the classical virtue ethical debate over the unity-disunity of the virtues, to endorse a pluralistic exemplar-based approach to moral education ("Empe"). After a few preliminary remarks, we argue that Empe amounts to defending "a prima facie" disunitarist perspective in moral theory, which admits both exemplarity in all respects (moral sainthood) and single-domain exemplarity (moral heroism). Then, we (...) evaluate the effectiveness of heroes and saints for moral education, according to four criteria derived from Empe. This analysis allows us to conclude that moral education should value both kinds of exemplars and, therefore, adopt weaker standards of exemplarity than the unitarist's ones. (shrink)

Conrad Gessner was town physician and lecturer at the Zwinglian reformed lectorium in Zurich. His approach towards the world and mankind was centred on his preoccupation with the human soul, an object of study that had challenged classical writers such as Aristotle and Galen, and which remained as important in post-Reformation debate. Writing commentaries on Aristotles De Anima was part of early-modern natural philosophy education at university and formed the preparatory step for studying medicine. This article uses the case study (...) of Gessners commentary on De Anima to explore how Gessners readers prioritised De Animas information. Gessners intention was to provide the students of philosophy and medicine with the most current and comprehensive thinking. His readers responses raise questions about evolving discussions in natural philosophy and medicine that concerned the foundations of preventive healthcare on the one hand, and of anatomically specified pathological medicine on the other, and Gessners part in helping these develop.

Identity criteria are used to confer ontological respectability: Only entities with clearly determined identity criteria are ontologically acceptable. From a logical point of view, identity criteria should mirror the identity relation in being reflexive, symmetrical, and transitive. However, this logical constraint is only rarely met. More precisely, in some cases, the relation representing the identity condition fails to be transitive. We consider the proposals given so far to give logical adequacy to inadequate identity conditions. We focus on the most refined (...) proposal and expand its formal framework by taking into account two further aspects that we consider essential in the application of identity criteria to obtain logical adequacy: contexts and granular levels.

The relevance of preschool children's understanding of nature, its elements, how it affects the behavior of human beings and how human being influences it, it helps to the identification of the necessary elements for the design of programs that have a significant impact in the development of environmental identity and the implementation of environmental education in the school curriculum in Mexico, in order to achieve the derivation of attitudes to preserve the environment from an early age. Under this logic, the (...) objective of the present study was to identify the components of the concept Nature, from drawings made by preschool children in a desert environment, this through a visual discursive analysis. It was made by 118 preschool students, whose ages range between 5 and 6 years; enrolled in four different schools in Hermosillo, Mexico, three located in the urban area and one on the coast of the State of Sonora. Participants were asked to draw the first thought that came to their minds when they heard the word nature. As a result, it was obtained with the representations of the images, that all the drawings present categories such as plants, animals, water bodies, celestial bodies, abiotic factors, natural locations, locations made by man and others. Finally, it was discovered that the analyzes showed a generalized idea of what nature represents by including elements of known flora and fauna, however, they did not capture elements of the desert region in which they live.

This work promotes the thesis that humans are naturally transhuman. In order to achieve this, we present in the first two sections some examples of technological devices assembled to human beings, and we critically review the assumptions and dichotomies on which the idea of human enhancement is based according to the ordinary transhumanist vision. Thirdly, we present the thesis of the Extended Mind to support our intuition. Fourthly, we dismantle the most relevant philosophical dichotomies that structure the transhumanist position. Finally, (...) we recapitulate the reasons why we should wake up from the transhumanist dream. (shrink)

This book addresses current threats to citizenship and democratic values posed by the spread of post-truth communication. The contributors apply research on moral, civic, and epistemic virtues to issues involving post-truth culture. The spread of post-truth communication affects ordinary citizens' commitment to truth and attitudes toward information sources, thereby threatening the promotion of democratic ideals in public debate. The chapters in this volume investigate the importance of helping citizens improve the quality of their online agency and raise awareness of the (...) risks social media poses to democratic values. The book moves from two initial chapters that provide historical background and overview of the present post-truth malaise, through a series of chapters that feature mainly diagnostic accounts of the epistemic and ethical issues we face, to the complexities of virtue-theoretic analyses of specific virtues and vices. Virtues, Democracy, and Online Media will be of interest to scholars and advanced students working in virtue ethics, epistemology, political philosophy, and media studies. (shrink)

_A resolute defense of philosophy and hermeneutics against the threats of dogmatism and relativism._.

Connecting Virtues examines the significant advances within the fast-growing field of virtue theory and shows how research has contributed to the current debates in moral philosophy, epistemology, and political philosophy. It includes groundbreaking chapters offering original solutions to long-standing issues, such as the plausibility of different lists of virtues, the relationship between virtues and the vices that oppose them, and the connection between moral and intellectual virtues. In addition, the volume offers insights into cutting-edge areas of application of the topic (...) of virtue, such as the role of intellectual virtues in an age of neuromedia, virtuous dispositions related to social epistemology, and the value of some neglected virtues for political philosophy. The book breaks down barriers between different philosophical perspectives on the study of the virtues—both to highlight the interplay and overlap among virtues pertaining to different philosophical areas, and to stress the peculiarity of specific virtues within their own fields. It is a unique and insightful collection of essays composed by some of the leading philosophers working on the topic. (shrink)

Background:Psychological abuse of older people is difficult to recognise; specifically, nursing home residents have been documented to be at higher risk of psychological abuse during daily care, such as during feeding. Healthcare professionals adopt positive and negative verbal prompts to maintain residents’ eating independence; however, negative prompts’ purposes and implications have never been discussed to date.Research aims:To critically analyse negative verbal prompts given during mealtimes as forms of abuse of older individuals and violation of ethical principles.Research design:This is a secondary (...) analysis of three cases of negative prompts that emerged in a large descriptive study based upon focus group methodology and involving 13 nursing homes and 54 healthcare professionals.Participants and research context:This study included 3 out of 13 nursing homes caring for residents with moderate/severe functional dependence in self-feeding mainly due to dementia; in these nursing homes, we conducted three focus groups and 13 healthcare professionals participated.Ethical considerations:This study was conducted in accordance with the Human Subject Research Ethics Committee guidelines after being approved by the Review Board of the Trust.Findings:With the intent of maintaining self-feeding independence, negative verbal prompts have been reported as being used by nursing home teams. By critically analysing these negative prompts, it turned out they could trigger intimidation, depression and anxiety and thus could be considered as forms of abuse; moreover, negative prompts can threaten the ethical principles of autonomy using a paternalist approach, beneficence and non-maleficence as with the intent to act in the best interests of residents they are harmed in their dignity and justice, given that residents who received negative prompts are treated differently from those who received positive prompts.Discussion:Eating should be a pleasant experience with a positive impact on physiological, psychological and social well-being. However, negative prompting can lead to abuse and violation of basic ethical principles, destroying the healthcare professional resident and relative relationships strongly dependent on trust.Conclusion:Negative verbal prompting must be avoided.

Usually within the context of computer simulations in quantum chemistry practices, there is a distinction between ab initio and semi-empirical methods. Related to this, a controversy within the scientific and philosophical communities came about regarding the superiority of the ab initio methods due to their theoretical rigor. In this article we re-evaluate the condition of the semi-empirical simulations in this area of research. We examine some of the aspects of this debate that have been considered in philosophy and provide additional (...) elements to the analysis. (shrink)

The first part of this paper will provide a reconstruction of Francis Bacon’s interpretation of Academic scepticism, Pyrrhonism, and Dogmatism, and its sources throughout his large corpus. It shall also analyze Bacon’s approach against the background of his intellectual milieu, looking particularly at Renaissance readings of scepticism as developed by Guillaume Salluste du Bartas, Pierre de la Primaudaye, Fulke Greville, and John Davies. It shall show that although Bacon made more references to Academic than to Pyrrhonian Scepticism, like most of (...) his contemporaries, he often misrepresented and mixed the doctrinal components of both currents. The second part of the paper shall offer a complete chronological survey of Bacon’s assessment of scepticism throughout his writings. Following the lead of previous studies by other scholars, I shall support the view that, while he approved of the state of doubt and the suspension of judgment as a provisional necessary stage in the pursuit of knowledge, he rejected the notion of acatalepsia. To this received reading, I shall add the suggestion that Bacon’s criticism of acatalepsia ultimately depends on his view of the historical conditions that surround human nature. I deal with this last point in the third part of the paper, where I shall argue that Bacon’s evaluation of scepticism relied on his adoption of a Protestant and Augustinian view of human nature that informed his overall interpretation of the history of humanity and nature, including the sceptical schools.
