Ernst Mayr argued that the emergence of biology as a special science in the early nineteenth century was possible due to the demise of the mathematical model of science and its insistence on demonstrative knowledge. More recently, John Zammito has claimed that the rise of biology as a special science was due to a distinctive experimental, anti-metaphysical, anti-mathematical, and anti-rationalist strand of thought coming from outside of Germany. In this paper we argue that this narrative neglects the important role played (...) by the mathematical and axiomatic model of science in the emergence of biology as a special science. We show that several major actors involved in the emergence of biology as a science in Germany were working with an axiomatic conception of science that goes back at least to Aristotle and was popular in mid-eighteenth-century German academic circles due to its endorsement by Christian Wolff. More specifically, we show that at least two major contributors to the emergence of biology in Germany—Caspar Friedrich Wolff and Gottfried Reinhold Treviranus—sought to provide a conception of the new science of life that satisfies the criteria of a traditional axiomatic ideal of science. Both C.F. Wolff and Treviranus took over strong commitments to the axiomatic model of science from major philosophers of their time, Christian Wolff and Friedrich Wilhelm Joseph Schelling, respectively. The ideal of biology as an axiomatic science with specific biological fundamental concepts and principles thus played a role in the emergence of biology as a special science. (shrink)

Whilst previous studies indicate perceived company ethicality as a driver of job seekers’ job-pursuit intentions, it is poorly understood how and why ethical market signals actually affect their application decisions. Perceptions of company ethicality result from market signals that are either within the control of the company and from market signals that are beyond the company’s control. Building on communication and information processing theories, this study therefore considers both types of ethical market signals, and examines the psychological mechanisms through which (...) they affect job seekers’ intention to apply for a job. The results from a controlled online experiment show that both types of ethical market signals increase job seekers’ job-pursuit intentions. These relationships are mediated by applicants’ attitude towards the job advertisement, their perceptions of corporate employment image and self-referencing. Consequently, the present study alerts practitioners to consider the effects of company-controlled and non-company-controlled ethical market signals, particularly when aiming to recruit highly-qualified millennial candidates.

This collective paper on radicalization and violent extremism part of the ‘Philosophy of education in a new key’ initiative by Educational Philosophy and Theory brings together some of the leading contemporary scholars writing on the most pressing epistemological, ethical, political and educational issues facing post-9/11 scholarship on radicalization and violent extremism. Its overall aim is to move beyond the ‘conventional wisdom’ associated with this area of scholarly research best represented by its many slogans, metaphors and other thought-terminating clichés. By providing (...) conceptual lenses on issues previously compartmentalized primarily [or even exclusively] in security and intelligence studies or at the fringes of scholarly interest, radicalization and violent extremism turn out to be much more complex than ‘radicalization studies’ has been eager to acknowledge.

The aim of this study was to assess nurses’ and physicians’ ethical dilemmas in clinical practice. Nurses and physicians of the Clinical Hospital Centre Rijeka were surveyed (N = 364). A questionnaire was used to identify recent ethical dilemma, primary ethical issue in the situation, satisfaction with the resolution, perceived usefulness of help, and usage of clinical ethics consultations in practice. Recent ethical dilemmas include professional conduct for nurses (8%), and near-the-end-of-life decisions for physicians (27%). The main ethical issue is (...) limiting life-sustaining therapy (nurses 15%, physicians 24%) and euthanasia and physician-assisted suicide (nurses 16%, physicians 9%). The types of help available are similar for nurses and physicians: obtaining complete information about the patient (37% vs. 50%) and clarifying ethical issues (31% vs. 39%). Nurses and physicians experience similar ethical dilemmas in clinical practice. The usage of clinical ethics consultations is low. It is recommended that the individual and team consultations should be introduced in Croatian clinical ethics consultations services. (shrink)

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

The paper is devoted to applications of algebraic logic to databases. In databases a query is represented by a formula of first order logic. The same query can be associated with different formulas. Thus, a query is a class of equivalent formulae: equivalence here being similar to that in the transition to the Lindenbaum-Tarski algebra. An algebra of queries is identified with the corresponding algebra of logic. An algebra of replies to the queries is also associated with algebraic logic. These (...) relations lie at the core of the applications.In this paper it is shown how the theory of Halmos (polyadic) algebras (a notion introduced by Halmos as a tool in the algebraization of the first order predicate calculus) is used to create the algebraic model of a relational data base. The model allows us, in particular, to solve the problem of databases equivalence as well as develop a formal algebraic definition of a database's state description. In this paper we use the term "state description" for the logical description of the model. This description is based on the notion of filters in Halmos algebras. When speaking of a state description, we mean the description of a function which realizes the symbols of relations as real relations in the given system of data. (shrink)

Mindfulness-based interventions have proved effective in reducing various clinical symptoms and in improving general mental health and well-being. The investigation of the mechanisms of therapeutic change needs methods for assessment of mindfulness. Existing self-report measures have, however, been strongly criticized on various grounds, including distortion of the original concept, response bias, and other. We propose a psychophysiological method for the assessment of the mindfulness learned through time-limited mindfulness-based therapy by people who undergo meditation training for the first time. We use (...) the individual pre-post-therapy changes (dERPi) in the event-related brain potentials (ERPs) recorded in a passive meditation task as a measure of increased mindfulness. dERPi is computed through multivariate assessment of individual participant's ERPs. We tested the proposed method in a group of about 70 recurrently depressed participants, randomly assigned in 1.7:1 ratio to mindfulness-based cognitive therapy (MBCT) or cognitive therapy (CT). The therapy outcome was measured by the long-term change (dDS) relative to baseline in the depression symptoms (DS) assessed weekly, for 60 weeks, by an online self-report questionnaire. We found a strong, highly significant, negative correlation (r = -0.55) between dERPi (mean = 0.4) and dDS (mean = -0.7) in the MBCT group. Compared to this result, the relationship between dDS and the other (self-report) measures of mindfulness we used was substantially weaker and not significant. So was also the relationship between dERPi and dDS in the CT group. The interpretation of dERPi as a measure of increased mindfulness was further supported by positive correlations between dERPi and the other measures of mindfulness. In this study, we also replicated a previous result, namely, the increase (dLCNV) of the late contingent negative variation (LCNV) of the ERP in the MBCT group, but not in the control group (in this case, CT). We interpreted dLCNV as a measure of increased meditative concentration. The relationship between dLCNV and dDS was, however, very week, which suggests that concentration might be relatively unimportant for the therapeutic effect of mindfulness. The proposed psychophysiological method could become an important component of a "mindfulness test battery" together with self-report questionnaires and other newly developed instruments. (shrink)

Im 2009 erschienenen Buch "Philosophie des Leidens" versucht Boris Wandruszka, jene immanente Lebensstruktur und Lebensdynamik aufzudecken, die zu den einfachsten und fundamentalen Strukturmomenten des Leidens vorstosst; diese erste "Wissenschaft vom Leiden" transzendierte daher nicht die Grenzen der Anschaubarkeit, sondern verblieb in der "Immanenz des 'inneren Lebens' bzw. des Erlebens". Im aktuellen Buch "Metaphysik des Leidens" werden die "realen Bedingungen der Moglichkeit von Leiden" ermittelt: Wie muss eine Welt beschaffen sein, damit darin ein leidendes Wesen erscheinen konne? Welche Rolle hat (...) das Leiden in Bezug zum fundamentalen Widerfahrnis-, Resonanz- und Responsivitatscharakter des Lebens? Es wird gezeigt, dass menschliches Leben, das einer plural-agonalen Welt ausgesetzt ist, nicht leidfrei moglich ist, dass aber andererseits das Leid nicht das letzte Wort sein kann, sondern notwendig auf Ganzheit, Reifung, Erlosung und Harmonie bezogen ist. Nur auf dem Hintergrund der Spannung zwischen absoluter Seins-, Sinn- und Lebensfulle und der stets problematischen und fragilen Teilhabe von Menschen am "absoluten und leiduberwindenden Urleben" kann Leiden entstehen, durchlitten, verstanden, aber auch uberwunden werden. Hier erreicht der "Opfergedanke", in dem das unvermeidliche Leid frei angenommen und dadurch transformiert wird, seine reinste und hochste Ausformung. Erst nach Klarung dieser Verhaltnisse wird die "Theodizeefrage" als "das Problem der Probleme" angegangen und am Leitfaden der Hiob-Erzahlung diskutiert. Letztlich erweist sich, dass trotz allem Schmerz, Mangel, Unrecht und Unsinn ein "Potential des Unendlichen" im Leiden verborgen liegt, das auf seine Uberwindung durch Sein-, Sinn- und Werterfullung, durch Tat, Erkenntnis und Liebe verweist und dass diese drei "Machte" der Leidensherausforderung bedurfen, um ihre Weite, Tiefe und Hohe auszuloten.

The presence of ibuprofen in wastewater is a topic of global interest, and the mechanisms and behavior of its correlation with its elimination in ecological systems, such as constructed wetlands, is a little known topic. The objective of this study was to perform a correlational analysis of the behavior of the emerging contaminant ibuprofen in a horizontally constructed wetland in a tropical climate planted with the ornamental plant Spathiphyllum blandum. 10 experimental units were used at the mesocosm level of 20 (...) L, 5 planted with Spathiphyllum B., and 5 without plants. The elimination of ibuprofen was measured and the correlation was analyzed using computational methods and neural networks. Spathiphyllum blandum was used in this study. The removal of ibuprofen in HC was significantly improved by up to 23% compared with that in non-planted systems. Based on the prediction obtained from ibuprofen in the effluent, it can be concluded that it has an exponential decay behavior tending to zero, and the model obtained explains in an acceptable way the relationship between the height of the plant and the concentration of ibuprofen in the effluent, reaffirming that this relationship is inverse. Further studies should be conducted to understand the behavior of these compounds in relation to different species of tropical plants. (shrink)

There is a growing trend in European countries for childbearing to occur later in women’s lives. The recent increase in the use of ART, together with the long-term trend towards later childbearing, raises questions as to the acceptable age of childbearing in contemporary society. ART legislation varies considerably across Europe and age limits for access to fertility treatment are rarely defined. The legislation takes into account the preferences of potential parents; children’s preferences, however, are not ascertained. The article discusses a (...) research method used in a survey of older children and young adults. The objective of the survey was to answer the following questions: What age would children prefer their parents to be if they could choose? What are their reasons? Respondents were asked the following question: “How old would you like your mother and father to be when you are 20 (version for respondents younger than 16) or 25 (version for those older than 16) if you could wave a magic wand?” Furthermore, their reasons for wishing a change were identified through an open question, “Why would you like to change the age of your parents?”.

Starting from the idea that functions are formally similar to actions in that they are described and explained in a similar way, so that both admit of an accordion effect, I turn to Anscombe’s insight that the point of practical reasoning is to render explicit the relation between the different descriptions of an action generated by the accordion effect. The upshot is, roughly, that an item has a function if what it does can be accounted for by functional reasoning. Put (...) differently, a part of a system has a function if what it does is a functional part of what the system does. (shrink)

Boris Kment takes a new approach to the study of modality that emphasises the origin of modal notions in everyday thought. He argues that the concepts of necessity and possibility originate in counterfactual reasoning, which allows us to investigate explanatory connections. Contrary to accepted views, explanation is more fundamental than modality.

This study aims to characterise Human Research Ethics Committee (HREC) members’ perceptions on five main themes associated with ethics reviews, namely, the nature of research, ethical/moral issues, assent, participants’ risk and HREC prerogatives issues. Three hundred and sixteen HREC members from over 200 HRECs throughout Australia responded to an online questionnaire survey. The results show that in general, HREC members’ beliefs are reasoned and align with sound principles of ethical reviews. There seems to be a disposition for living up to (...) ethical/moral values, avoiding the issue of consent waivers and respecting participants’ welfare, as well as a sense of ambiguity about HREC prerogatives. Problematic areas were a tendency towards over-valuing quantitative research methods for their perceived validity and a neutral view on issuing consent waivers to participants with intellectual disability and, finally, the belief that research that limits disclosure, plans deception or actively conceals is morally unjustifiable. Implications for professional development and policy-making are discussed. (shrink)

We further investigate a divisibility relation on the set of BN ultrafilters on the set of natural numbers. We single out prime ultrafilters (divisible only by 1 and themselves) and establish a hierarchy in which a position of every ultrafilter depends on the set of prime ultrafilters it is divisible by. We also construct ultrafilters with many immediate successors in this hierarchy and find positions of products of ultrafilters.

As Sartre pointed out, philosophical questions are questions that each generation must ask themselves because only this promotes the feeling of being alive, which is especially true for existential questions closely related to time–space, the moment, and our society. Sartre placed his philosophy of existentialism in wartime and the social conditions of the time at the beginning of the 20th century. We can equate these conditions with today’s conditions; we are once again facing threats of war, and once again, we (...) are facing chaotic conditions that increasingly lead to absurdity but are also entirely different. Today, at the beginning of the 21st century, the clarity and disambiguation of the 20th century no longer exist, as the relationships between beings and the world have drastically changed. We can observe that (1) the world is not one; there are two worlds, the physical and the cyber world and (2) being is not one; there are two beings (entities), human and AI-based forms of artificial life (ALF), between which there is a permanent tension. We advocate the thesis that in the society of the future, man must still play a master role; he must still be the being who will guide this society. Also, as Sartre claimed, each era must create its philosophy and consider real time–space. Responses to changes in this time–space also relate to existentialism in the 21st century. In this context, it is necessary to redefine the view of the future and the guidelines for the development of future society. (shrink)
