The authors present the main ideas of the computer-assisted proof of Mischaikow and Mrozek that chaos is really present in the Lorenz equations. Methodological consequences of this proof are examined. It is shown that numerical calculations can constitute an essential part of mathematical proof not only in the discrete mathematics but also in the mathematics of continua.

ABSTRACT This article concentrates on the care for people who suffer from progressive dementia. Dementia has a great impact on a person’s well‐being as well as on his or her social environment. Dealing with dementia raises moral issues and challenges for participants, especially for family members. One of the moral issues in the care for people with dementia is centred on responsibilities; how do people conceive and determine their responsibilities towards one another? To investigate this issue we use the theoretical (...) perspective of Margaret Walker. She states that ideas about identity play a crucial role in patterns of normative expectations with regard to the distribution of responsibilities in daily practices of care. The results of this study show how the identity of a family‐member is put under pressure and changes during her loved one’s illness that leads to difficulties and misunderstandings concerning the issue of responsibility. These results offer an insight into the complexities of actual practices of responsibility and highlight the importance for those caring for people with dementia of attending carefully to how they see themselves and how they see other people involved (Who am I? Who do I want to be for the other?). Answers to such questions show what people expect from themselves and from one another, and how they, at any rate, are distributing responsibilities in a given situation. Professional caregivers should take into account that family members might have different ideas about who they are and consequently about what their responsibilities are. (shrink)

Strategic games require reasoning about other people’s and one’s own beliefs or intentions. Although they have clear commonalities with psychological tests of theory of mind, they are not clearly related to theory of mind tests for children between 9 and 10 years of age “Flobbe et al. J Logic Language Inform 17(4):417–442 (2008)”. We studied children’s (5–12 years of age) individual differences in how they played a strategic game by analyzing the strategies that they applied in a zero, first, and (...) second-order reasoning task. For the zero-order task, we found two subgroups with different accuracy levels. For the first-order task, subgroups of children applied different suboptimal strategies or an optimal strategy. For the second-order task only suboptimal strategies were present. Strategy use for all tasks was related to age. The 5- and 6-year old children were additionally tested on theory of mind understanding and executive functioning. Strategy-use in these children was related to working memory, but not to theory of mind after correction for age, verbal ability and general IQ. (shrink)

Since Carol Gilligan's In a Different Voice (1982) the ethics of care has developed as a movement of allied thinkers, in different continents, who have a shared concern and who reflect on similar topics. This shared concern is that care can only be revalued and take its societal place if existing asymmetrical power relations are unveiled, and if the dignity of care givers and care receivers is better guaranteed, socially, politically and personally. In this first volume of a new series (...) leading care ethicists from Europe and the United States focus on the moral significance of two concepts in the debate that ask for further reflection. In discussion with the work of Axel Honneth on recognition and the work of Emmanuel Housset on compassion a contribution is made to a reconsideration of recognition and compassion from an ethics of care perspective. This volume contains contributions by Andries Baart, Estelle Ferrarese, Chris Gastmans, Mieke Grypdonck, Emmanuel Housset, Carlo Leget, Hilde Lindemann, Axel Liegeois, Christa Schnabl, Joan C. Tronto, Annelies van Heijst, Linus Vanlaere, Frans Vosman and Margaret Urban Walker. (shrink)

Background: Clinical genomic implementation studies pose challenges for informed consent. Consent forms often include complex language and concepts, which can be a barrier to diverse enrollment, and these studies often blur traditional research-clinical boundaries. There is a move toward self-directed, web-based research enrollment, but more evidence is needed about how these enrollment approaches work in practice. In this study, we developed and evaluated a literacy-focused, web-based consent approach to support enrollment of diverse participants in an ongoing clinical genomic implementation study. (...) Methods: As part of the Cancer Health Assessments Reaching Many (CHARM) study, we developed a web-based consent approach that featured plain language, multimedia, and separate descriptions of clinical care and research activities. CHARM offered clinical exome sequencing to individuals at high risk of hereditary cancer. We interviewed CHARM participants about their reactions to the consent approach. We audio recorded, transcribed, and coded interviews using a deductively and inductively derived codebook. We reviewed coded excerpts as a team to identify overarching themes. Results: We conducted 32 interviews, including 12 (38%) in Spanish. Most (69%) enrolled without assistance from study staff, usually on a mobile phone. Those who completed enrollment in one day spent an average of 12 minutes on the consent portion. Interviewees found the information simple to read but comprehensive, were neutral to positive about the multimedia support, and identified increased access to testing in the study as the key difference from clinical care. Conclusions: This study showed that interviewees found our literacy-focused, web-based consent approach acceptable; did not distinguish the consent materials from other online study processes; and valued getting access to testing in the study. Overall, conducting empirical bioethics research in an ongoing clinical trial was useful to demonstrate the acceptability of our novel consent approach but posed practical challenges. (shrink)

Experiential education produces numerous benefits to students in terms of higher order thinking skills such as the ability to evaluate, analyze, and synthesizeinformation , engagement , and work-readiness . Partnering with community organizations provides a means to create experiential education opportunities for students. In this symposium, we discussed three examples of experiential education to promote learning around themes of sustainability, providing a brief outline of the activities, the intended outcomes, and the lessons learned from our experiences. We concluded with a (...) meditation on the importance of working with community partners and managing expectations so that students, the community, and the institutions gain the best possible outcomes when creating town-gown partnerships for sustainability education.

Schools are an essential part of students’ lives and can promote and facilitate their well-being. Although research on well-being among school-aged children and adolescents has distinguished subjective well-being from social well-being, very few studies examined student’s social well-being at school. SWS is understood as students’ valuation of the circumstances and functioning of their school. This framework posits that the context of the schools can shape students’ perception of feeling integrated and making significant contributions to their schools. However, not much is (...) known regarding the joint contribution of individual, family, and school characteristics to students’ SWS. This study analyzed these joint contributions in a nationally representative sample of 6,389 children and adolescents enrolled in 5th–11th grades. Findings show that being female and younger were individual predictors of SWS. Students’ satisfaction with their family and fewer changes of schools were also significant contributors. When students’ perceptions of their schools were incorporated, the individual and family characteristics decreased or lost significance. In the full model, the highest contribution to SWS was explained by the school-level aggregated perception of school climate. These findings call for integrated policies and practices to foster students’ sense of belonging, feeling integrated, and contribution to their schools, with a focus on school-level interventions to improve SWS through positive and engaging school climates that foster students’ sense of agency.

Making adaptive choices between solution strategies is a central element of contemporary mathematics education. However, previous studies signal that students make suboptimal choices between mental and written strategies to solve division problems. In particular, some students of a lower math ability level appear inclined to use mental strategies that lead to lower performance. The current study uses a pretest-training-posttest design to investigate the extent to which these students’ choices for written strategies and performance may be increased. Sixth graders of below-average (...) mathematics level (N = 147) participated in one of two training conditions: an explicit-scaffolding training designed to promote writing down calculations or a practice-only training where strategy use was not explicitly targeted. Written strategy choices and performance increased considerably from pretest to posttest for students in both training conditions, but not in different amounts. Exploratory results suggest that students’ strategy choices may also be affected by their attitudes and beliefs and the sociocultural context regarding strategy use. (shrink)

What is animal welfare? Why has it proved so difficult to find a definition that everyone can agree on? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as 'health and animals having what they want', a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we (...) need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare. But, can we really understand what animals want? A consistent theme running through the book is that not only is it possible to establish what animals want, but that this information is vital in helping us to make sense of the long and often confusing list of welfare measures that are now in use such as 'stress' and 'feel good hormones', expressive sounds and gestures, natural behaviour, cognitive bias, and stereotypies. Defining welfare as 'health and what animals want' allows us to distinguish between measures that are simply what an animal does when it is alert, aroused, or active and those measures that genuinely allow us to distinguish between situations the animals themselves see as positive or negative. Sentience (conscious feelings of pleasure, pain, and suffering) is for many people the essence of what is meant by welfare, but studying consciousness is notoriously difficult, particularly in non-human species. These difficulties are discussed in the context of our current - and as yet incomplete - knowledge of human and animal consciousness. Finally, the book highlights some key ideas in the relationship between animal welfare science and animal ethics and shows how closely the well-being of humans is linked to that of other animals. The Science of Animal Welfare is an ideal companion for undergraduate and graduate students taking courses in animal behaviour and welfare, as well as for professional researchers, practitioners and animal welfare consultants. At the same time, it is easily understandable to non-scientists and anyone without prior knowledge but with an interest in animals and the rapidly evolving science of animal welfare. (shrink)

In 1976, I met John Bell several times in CERN and we talked about a possible violation of optical theorem, purity tests, EPR paradox, Bell’s inequalities and their violation. In this review, I resume our discussions, and explain how they were related to my earlier research. I also reproduce handwritten notes, which I gave to Bell during our first meeting and a handwritten letter he sent to me in 1982. We have never met again, but I have continued to discuss (...) BI-CHSH inequalities and their violation in several papers. The research stimulated by Bell’s papers and experiments performed to check his inequalities led to several important applications of quantum entanglement in quantum information and quantum technologies. Unfortunately, it led also to extraordinary metaphysical claims and speculations which in our opinion John Bell would not endorse today. BI-CHSH inequalities are violated in physics and in cognitive science, but it neither proved the completeness of quantum mechanics nor its nonlocality. Quantum computing advantage is not due to some magical instantaneous influences between distant physical systems. Therefore one has to be _cautious in drawing-far-reaching philosophical conclusions from Bell’s inequalities_. The true resource for quantum computing is contextuality and not nonlocality. (shrink)

In a world increasingly concerned with the human species and its future, Marian Stamp Dawkins argues that we need to rethink some of the fundamental questions regarding animal welfare. How are we justified in projecting human emotions on to animals? What kind of mental lives do they have? What can science tell us about their quality of life?

I this paper I give minimal axioms for the ontology of time, especially A-theories and B-theories and I derive philosophically interesting lemmas. The exercise is set-theoretical, defining all notions and indicating assumptions and philosophical points of disagreement, while being easy to translate to other formal expressions . The issue of a logic for A-theories of time is treated towards the end, where I sketch ‘copresent’ operators for capturing the idea of temporal passage. The main conclusion will be that, while circularity (...) threatens both families of theories, the growing block theory (belonging to the A-theory) is the least objectionable philosophically.

Ota Weinberger was a Czech-Austrian jurist, whose core academic work on issues of democracy was mostly published in the 1990s. In his writings, he focused primarily on legal philosophy from a positivist perspective. However, there are also significant overlaps with the field of political theory as Weinberger examined the conditions for the functioning of contemporary democracies. In this paper, some of the main features of his conception of the so-called “structured democracy” are clarified. The conception opposed several other democratic theories, (...) especially the elitist (Schumpeterian), the majoritarian, but also the discursive one, as represented by Jürgen Habermas, with whom Weinberger fundamentally disagreed. The paper focuses on several key elements of his theory, such as the leading ideas, the role of institutions, open society, and his critique of marketing methods in politics. (shrink)

This article serves as an introduction to the special issue discussing the usefulness of philosophy in managerial practice. We present the papers included in this special issue and identify keynote directions for further research. The initial intention of the call for papers was to promote this topic on research agendas by offering a platform for discussing if, why, and how philosophy can complement and enhance management practice. Now that this special issue has been published, we see a broader significance: the (...) arguments explored here are a starting point for more in-depth studies of the connections that can occur between specific philosophical concepts, theories, methods on the one hand, and concrete managerial practices on the other.

I aim to develop a tool for comparing theories of vagueness, using Structured Query Language. Relevant SQL snippets will be used throughout.

It is sometimes argued that contextualism cannot explain (dis)agreements concerning matters of personal taste because it treats sentences involving predicates of taste as indexical. I aim to weaken this charge. Given the idea that people sometimes use indexical sentences to express (dis)agreements about taste, two kinds of (dis)agreement are distinguished, namely doxastic and non-doxastic. Taste (dis)agreements are better explained in terms of the later kind, in which case they become amenable to contextualist treatment. It is argued that if something instantiates (...) a taste property (like being tasty for A), it has to instantiate a corresponding attitudinal property (like being liked by A). Based on this, utterances of taste sentences express propositions that concern tastiness of something (e.g., that X is tasty for A) and these propositions entail other propositions that concern non-doxastic attitudes the speakers bear toward something (e.g., that X is liked by A). One speaker is claimed to (dis)agree with another speaker provided their respective entailed propositions feature (in)compatible non-doxastic attitudes. Although this explanation is similar to hybrid accounts that are currently growing in popularity, it departs from them in some notable respects. (shrink)

Using a religious studies methodology, this paper offers a detailed contextual mapping and a structural configuration of how collective violence is justified in Orthodox Christianity. The research design is explanatory, whereby the functional perspectives of doctrine, ethics and worship are all investigated and probed as phenomena of lived religion and orthopraxy. While predominantly initiatory and pedagogical, the paper also proposes a systematic platform for advanced research on this subject, by flagging contexts, themes and areas of inquiry that a researcher might (...) examine in order to untangle the inner workings of the justification of violence in the mind of the Orthodox. Given the ongoing Russian War on Ukraine, relevant samples are drawn from this case.Contribution: This paper outlines the Orthodox Christian justification of violence from the perspectives of doctrine, ethics and ritual and identifies pivotal areas of ambiguity between orthodoxy and orthopraxy.

Jak i dlaczego powstał Wszechświat? Problem z naukowym wyjaśnieniem istnienia Wszechświata polega na tym, że zakłada ono pewną fizyczną przyczynę jego istnienia. Ale jakakolwiek fizyczna przyczyna Wszechświata musi być częścią Wszechświata, którego zaistnienie ma wyjaśnić. Z tego powodu każde czysto naukowe wyjaśnienie istnienia Wszechświata jest skazane na zapętlenie. Być może żadna teoria naukowa nie może przerzucić mostu pomiędzy absolutną nicością a istniejącym już Wszechświatem.Okazuje się jednak, że gdy metafizyczne pytanie typu: dlaczego istnieje Wszechświat? zamienimy na „bardziej naukowe”: w jaki sposób (...) powstał Wszechświat?, to mamy szansę na gruncie fizyki przedstawić współczesną wersję „historii” powstania Wszechświata. Kosmolog Lawrence M. Krauss twierdzi, że w tym celu wystarczy porzucić mętne – z punktu widzenia fizyki – pojęcie absolutnej nicości i za punkt wyjścia uznać fizyczną próżnię. Ponieważ – jak wynika z mechaniki kwantowej – kwantowa próżnia to dalece nie to samo co nicość metafizyczna, możliwe jest – w świetle naszej współczesnej wiedzy – powstanie Wszechświata z „niczego”.

Ostatnie osiągnięcia w kosmologii i fizyce cząstek prowadzą do zaskakujących wniosków. Sugerują istnienie wielu odmiennych – od naszego – wszechświatów. Hipoteza multiwszechświata pojawia się jako wynik rozważań przeprowadzanych zarówno w największej skali na gruncie tzw. teorii wiecznej, chaotycznej inflacji jak i w skali najmniejszej z możliwych – jako wniosek płynący z teorii superstrun, wyartykułowany jako propozycja tzw. kosmicznego „krajobrazu”. Koncepcja multiwszechświata mogłaby w racjonalny sposób wyjaśnić pochodzenie naszego Wszechświata, sposób jego zaistnienia a także szczegóły jego funkcjonowania, w szczególności kwestię jego (...) „dostrojenia” dla rozwoju życia. Ale czy spekulacje na temat wszechświatów, których nigdy nie będziemy mogli zobaczyć oparte na teoriach, które być może nigdy nie będą testowalne empirycznie są jeszcze nauką czy już filozofią?

Celem artykułu jest przedstawienie nauczania Kościoła jako wykraczającego poza błędny i rozłączny podział etyki na deontologię i teleologię. Autor przypomina szerokie tło przemian kulturowych, które towarzyszyły kontrowersjom wokół encykliki bł. Pawła VI "Humanae vitae". Teologiczna kontestacja nauczania Magisterium była powodem napisania przez św. Jana Pawła II encykliki "Veritatis splendor". Papież rozwiewa doktrynalne wątpliwości zasiane przez proporcjonalistów, przedstawiając im niezwykle przemyślaną i tradycyjną koncepcję źródeł moralności. Wychodząc od priorytetu celowości ludzkiego działania Papież podkreślił wagę przedmiotu czynu. Dla moralnego dobra ludzkiego czynu (...) konieczne jest jego podwójne właściwe odniesienie: wertykalnie do celu ostatecznego, czyli Boga, oraz horyzontalnie wobec człowieka poprzez przedmiotową zgodność działania z ludzkim dobrem. Papieskie rozważania zostają uzupełnione komentarzem do "Summy Teologii" św. Tomasza, który w analogiczny sposób przedstawia źródła moralności ludzkiego czynu. Rozróżniając wewnętrzny i zewnętrzny akt woli, św. Tomasz pokazuje właściwe źródła moralności każdego z tych aktów. W pierwszym przypadku jest to właściwy przedmiot woli, który jest tożsamy z dobrem; natomiast w drugim – konieczny jest ponadto właściwy przedmiot innych władz. Właściwa antropologia przywraca fundament pod adekwatne rozumienie zarówno prawa naturalnego, jak i potrzebę etyki cnót, która okazuje się wielką praktyczną pomocą dla człowieka w drodze do właściwej mu doskonałości. Przedstawione podstawowe prawdy nauczane od lat przez Magisterium o tyle domagają się przypomnienia, że współczesna dominująca kultura wytrwale dekonstruuje racjonalny porządek tego nauczania czyniąc zeń karykaturę. Papieskie analizy pozwalają oczyścić etyczne kryteria rozeznawania dobra i zła, przypominając o zaproszeniu do piękna teologalnego życia w Chrystusie. Umożliwia ono zdrowy krytyczny osąd konkretnych sytuacji, jak również możliwość uniknięcia rozpowszechnionych współcześnie błędów i wynikającego z nich kryzysu tożsamości. (shrink)

The PhD thesis advances a new approach to vagueness as dispersion, comparing it with the main philosophical theories of vagueness in the analytic tradition.

A constant of Frege’s writing is his rejection of indeterminate predicates as found in natural language. This paper follows Frege’s remarks on vagueness from the early "Begriffsschrift” to his mature works, drawing brief parallels with the main contemporary theories of vagueness. I critically examine Frege’s arguments for the inconsistency of natural language and argue that the inability to accommodate vagueness in his mature ontology is mainly due to heuristic rules of thumb which Frege took as essential, not to a deep (...) problem in his fundamental apparatus.

As cardiopatias congênitas são caracterizadas por anormalidade na estrutura cardiovascular, presente desde a vida fetal, sendo estimados 30 mil casos por ano, no Brasil. Apresentam alta taxa de mortalidade, requerendo, muitas vezes, hospitalizações, intervenções e cirurgias. É necessário atentar para necessidades das figuras maternas e paternas e suas formas de enfrentamento, pois fazem parte do suporte na recuperação da criança. Este estudo transversal objetivou identificar as estratégias de enfrentamento adotadas pelos pais, durante a hospitalização da criança, verificar se existe diferença (...) entre os gêneros. Foram avaliados 20 cuidadores, em acompanhamento ao filho hospitalizado para tratamento de cardiopatia congênita. Responderam questionário sociodemográfico e Escala de Enfrentamento de Problemas. Verificou-se que não há diferença na adoção de estratégias entre cuidadores materno e paterno, entretanto observou-se correlação entre fatores sociodemográficos e predominância do enfrentamento focado no problema e religiosidade.

Every professionally managed project is performed accordingly to precise defined principles, methods and a plan. As well, IT projects, which are major business ventures globally these days, are governed with similar approach. Defining objectives and project framework, selecting resources, drafting schedules are a fundamental skills, which can be taught at every basic business course. It seems to be that it is enough to acquire appropriate knowledge in area of project management to be successful IT manager in spite of the size (...) and the type of the venture. Still, only 16% ERP projects are successful, 84% projects do not meet deadlines and business goals and 78% projects overrun budgets. By paradox, to solve above presented business, economic problem it is necessary to address it by developing axiological research. It is based on the principle that empathy is the third perspective that is build in to the well know Game Theory model which consists of two perspectives: trust and loyalty (Deutsch). In this case, in the process of selecting an appropriate type of the game, between a customer and a vendor, we have to base on a better understanding of needs and axiological profiles on both sites. In other words, if the business goal of the partner is better defined and understood and if it is assumed that the success of one site depends on the other, the final effect, by definition, is almost guaranteed. To achieved that, it is a must for every IT manager to work on developing, the so called business empathy instead of just useless promoting the assertive business philosophy. (shrink)

The main objective of the Flemish research project ‘Nanotechnologies for tomorrow’s society’ (NanoSoc) is to develop and try out an interactive process as a suitable methodology for rendering nanoresearchers aware of underlying assumptions that guide nanotech research and integrating social considerations into the research choices they face. In particular, the NanoSoc process should sustain scientists’ capacities to address growing uncertainties on the strategic, scientific and public acceptance level. The article elaborates on these uncertainties and involved dilemmas scientists are facing and (...) proposes a process approach which addresses strategic uncertainty by alternating between ‘visioning’ and ‘technology assessment’; a process design which manages complexity by promoting reflexivity among scientists by exposing them to deliberations in civil society (social experts, stakeholders, citizens) on plausible futures with nanotechnologies; and as an answer to societal ambivalence, certain process quality requirements such as an attitude of perplexity or openness towards ‘plurality’ and an attitude of ‘temporary closure’, both in support of understanding and learning from differences.

Naturalized bioethics represents a revolutionary change in how health care ethics is practised. It calls for bioethicists to give up their dependence on utilitarianism and other ideal moral theories and instead to move toward a self-reflexive, socially inquisitive, politically critical, and inclusive ethics. Wary of idealisations that bypass social realities, the naturalism in ethics that is developed in this volume is empirically nourished and acutely aware that ethical theory is the practice of particular people in particular times, places, cultures, and (...) professional environments. These essays situate the bioethicist within the clinical or research context, take seriously the web of relationships in which all human beings are nested, and explore a number of the different kinds of power relations that inform health care encounters. Naturalized Bioethics aims to help bioethicists, doctors, nurses, allied health professionals, disability studies scholars, medical researchers, and other health professionals address the ethical issues surrounding health care.
