The theories of pre-existence and epigenesis are typically taken to be opposing theories of generation in the seventeenth and eighteenth centuries. One can be a pre-existence theorist only if one does not espouse epigenesis and vice versa. It has also been recognized, however, that the line between pre-existence and epigenesis in the nineteenth century, at least, is considerably less sharp and clear than it was in earlier centuries. The debate (1759-1777) between Albrecht von Haller and Caspar Friedrich Wolff on (...) their theories of generation is usually taken to be a debate between a pre-existence theorist and an epigeneticist, and the supposed fact that these two theories of generation are mutually exclusive explains (so the story goes) the divide between Haller and Wolff. However, it’s not clear that Haller endorsed an especially robust form of pre-existence, and nor is it clear that Wolff’s theory of generation -- once he considered it carefully -- is clear epigenetic. Rather, Haller’s theory of generation is marked by traces of epigensis and Wolff’s theory has elements of pre-existence theory. This is not to say that their theories of generation are basically the same, but the debate between the two ought not to be framed in terms of pre-existence versus epigenesis. Their points of difference must be explained in some other way. In this way, their controversy bears characteristics of similar disputes over generation in the nineteenth century more than it resembles those in the seventeenth century. In this paper, I argue that (a) Haller’s and Wolff’s theories both blend elements from pre-existence and epigenesis; (b) but there are still deeply-rooted differences between the two generation theories; (c) one source of these differences is that Haller and Wolff have divergent conceptions of what an adequate explanation is; (d) we can see that they have different conceptions of what constitutes an adequate explanation by paying heed to their evaluations of Descartes’ epistemology and methodology in his theory of generation (such as it is); and (e) this shows that one of the main differences between Haller’s generation theory and that of Wolff is the degree to which each thinks we need to (and indeed can) explain the nature of the causes -- both efficient and final -- at play during the formation of organic beings.

In this paper we consider the effect of unitarity bounds sb⩾s≡(E1+E2) cms 2 for the recently proposed types of nonderivative 4-fermion contact interactions. To this purpose we decompose the helicity amplitudes at c.m.s. into partial waves. The bounds are defined to hold for all reaction channels due to the same type of contact interaction. We find sb=τ4π/κ. Here κ is the coupling constant. The factor τ depends on the type of coupling and on the different cases to identify the fermions. (...) It ranges from 1/3 to 4. (shrink)

ZusammenfassungIn der Antike wie in der zeitgenassischen Philosophie wird die Frage diskutiert, ob sprachli‐che Bedeutungen auf Übereinkunft beruhen. In unserer Zeit heisst die Frage, inwieweit sprachliche Verständigung durch Konventionen bestimmt ist. Ich versuche zu zeigen, dass in den Regelbrauch, der sprachliches Verhalten teitet, zwar übereinkünfte eingehen können, ihn aber nicht wesentlich auszeichnen. Von da her erhält auch die Behandlung der Frage im Kratylos neue Aspekte: Der Regelbrauch, in den die ursprüngliche Übereinkunft zwar einge‐gangen ist, garantiert den Bezug der Narnen, aber (...) nicht auch die Bedeutung der Wörter.SummaryIn Antiquity, just as in contemporary philosophy, it was asked whether linguistic meaning is a matter of convention. Nowadays the question takes the following form: “to what extent is linguistic communication determined by convention?” I attempt to show that although there may be conventions among the rules governing linguistic behavior, they are not in any essential way distinctive of those rules. As a result of this view there are also new aspects to be considered in the treatment of the question in the Cratylus: the rules, which the initial convention indeed concerns, guarantee the reference of names but not the meaning of other kinds of words.RésuméDans ľAntiquité tout comme dans la philosophie contemporaine, on s'est demandé si Ies significations linguistiques reposent sur une convention. Aujourd'hui, la question se pose sous la forme suivante: dans quelle mesure la communication linguistique est‐elle déterminée par convention? J'essaye de montrer que, parmi les régies qui gouvernent le comportement linguistique, il peut y avoir des conventions, mais que le caractère conventionnel n'en est pas un critère distinctif. De ce point de vue, le traitement de la question dans le Cratyle révèle de nouveaux aspects: les règies, qui tiennent certes compte de la convention primitive, garantissent la référence des noms mais ne garantis‐sent pas celle des autres mots.

Darwins bahnbrechendes Werk 'Über die Entstehung der Arten' (1859) löste eine neue Debatte aus, die weniger durch wissenschaftliche Forschung als durch weltanschauliche Proklamationen geprägt war. Sie nahm in Deutschland einen anderen Verlauf als in England: Die dort noch starke Physikotheologie war in Deutschland bereits einflußlos geworden, und der vorangegangene Materialismus-Streit hatte den Boden für die Rezeption der Lehre Darwins vorbereitet. Von Seiten des weltanschaulichen Materialismus wurde der Darwinismus wegen seiner Eliminierung eines zwecksetzenden göttlichen Verstandes als unverhoffte Bestätigung angesehen und als (...) eine neue und zudem wissenschaftlich abgesicherte "Schöpfungstheorie" rezipiert und zum Schlüssel für die Lösung aller wissenschaftlichen und philosophischen Rätsel stilisiert.

The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

Die Physikotheologie leitet Gottes Schöpferkraft, Weisheit und liebende Vorsorge aus Schönheit, Funktionalität und Ordnung seiner Schöpfung ab. Diese Theologierichtung - Vorläufer des Intelligent Design Movement? - wird, von Natürlicher Theologie und Naturrecht ausgehend, von Cicero über Calvin, Luther, Kant, Barth und Gogarten besprochen. Ist diese Theologierichtung ein Zugang zu Gott neben der Offenbarung? Der Berner Anatom und Botaniker Albrecht von Haller (1708-1777), ein physikotheologisch denkender Gelehrter, hat als Calvinist das Christentum gegen Voltaire und materialistischen Atheismus kämpferisch verteidigt. Hallers Interpretation (...) der Bibel als von Gott eingegebenes Menschenwort - nicht als Verbalinspiration - ist gerade in der Kreationismus-Diskussion lesenswert. Man würde heute Haller als Anhänger des Intelligent Design einordnen: dass es eine evolutionäre Entwicklung zum Überleben der Schöpfung gibt, ist Gottes Plan zu danken. (shrink)

SummaryThis article approaches eighteenth-century views on scientific academies by examining Haller's utterances, public and private, especially those occasioned by the founding of the Göttingen Society. It deals in turn with his understanding of the distinctive purpose of academies, with his explanation of the chief ways in which they realized this end, with his thoughts on their broader usefulness, and finally with his various reasons for considering close ties with the state to be essential to their productive and harmonious operations.

This paper describes the perspectives of stakeholders within the North American dairy industry on key issues affecting the welfare of dairy cattle. Five heterogeneous focus groups were held during a dairy cattle welfare meeting in Guelph, Canada in October 2012. Each group contained between 7 and 10 participants and consisted of a mix of dairy producers, veterinarians, academics, students, and dairy industry specialists. The 1-h facilitated discussions were audio-recorded and transcribed verbatim. Content analysis of the resulting transcripts showed that participants (...) across all stakeholder categories identified lameness as the most important welfare issue facing dairy cattle. Other prominent issues of concern included cow comfort, disease, on-farm mortality, stockmanship, painful procedures, injuries, cull cow management, calf management, and restriction of behavioural freedoms. Participants typically gave several reasons for why they considered issues problematic. Underlying reasons were grouped according to animal-centered concerns [at both the individual and at the herd level ] and industry-centered concerns . This analysis identified areas of shared concern among diverse stakeholder groups, which should aid in the development of standards and policies that satisfy stakeholders within and external to the dairy industry.

Mitochondrial dysfunction has long been considered a key mechanism in the ageing process but surprisingly little attention has been paid to the impact of mitochondrial number or density within cells. Recent reports suggest a positive association between mitochondrial density, energy homeostasis and longevity. However, mitochondrial number also determines the number of sites generating reactive oxygen species (ROS) and we suggest that the links between mitochondrial density and ageing are more complex, potentially acting in both directions. The idea that increased density, (...) especially when combined with mitochondrial dysfunction, might accelerate ageing is supported by a negative correlation between mitochondrial density and maximum longevity in an interspecies comparison in mammals, and by evidence for an intimate interconnection between cellular ROS levels, mitochondrial density and cellular ageing. Recent data suggest that retrograde response, which activates mitochondrial biogenesis, accompanies cellular ageing processes. We hypothesise that increased mitochondrial biogenesis, and possibly also impaired degradation and segregation of mitochondria, if occurring as adaptation to pre‐existing mitochondrial dysfunction, might aggravate ROS production and thus actively contribute to ageing.

ABSTRACTWe often use our own emotions to understand other people’s emotions. However, emotional egocentric biases, namely the tendency to use one’s own emotional state when relating to others...

In recent years, scholars have come to understand emotions as dynamic and socially constructed—the product of interdependent cultural, relational, situational, and biological influences. While researchers have called for a multilevel theory of emotion construction, any progress toward such a theory must overcome the fragmentation of relevant research across various disciplines and theoretical frameworks. We present affect control theory as a launching point for cross-disciplinary collaboration because of its empirically grounded conceptualization of social mechanisms operating at the interaction, relationship, and cultural (...) levels, and its specification of processes linking social and individual aspects of emotion. After introducing the theory, we illustrate its correspondence with major theories of emotion construction framed at each of four analytical levels: cultural, interactional, individual, and neural.

Die Entwicklung der Philosophie in Österreich unterscheidet sich in markanter Weise von der Hauptlinie der philosophischen Entwicklung in Deutschland. Dabei fällt bei der österreichischen Philosophie vor allem die konsequente Orientierung an den Wissenschaften auf. In der philosophiegeschichtlichen Forschung sind für diese Besonderheit der österreichischen Philosophie z. B. von Otto Neurath, Rudolf Haller, Friedrich Stadier und J.C. Nyiri verschiedene Erklärungen vorgeschlagen worden. In diesen spielen in jeweils unterschiedlicher Weise Faktoren der spezifisch österreichischen Entwicklungen in historischer, institutioneller, politischer und religiöser Hinsicht (...) eine Rolle. Der vorliegende Aufsatz kritisiert demgegenüber bereits die diese Erklärungsversuche tragende Fragestellung: Die philosophischen Entwicklungen in Österreich bedürfen - so lautet die neue These - gar nicht einer besonderen Erklärung; denn sie stellen den geistesgeschichtlichen Normalfall dar. Vielmehr ist eine Erklärung dafür notwendig, daß sich die wissenschaftliche Philosophie und die mit ihr verbundenen Charakterzüge stilistischer Klarheit, technischer Kompetenz, systematischer Orientierung, Spezialisierung und Professionalisierung im gleichen Zeitraum nicht auch in Deutschland entwickelt haben. Eine solche Erklärung läßt sich - so eine weitere These des Aufsatzes - ziemlich leicht aus der besonderen Rolle der (traditionellen idealistischen) Philosophie im deutschen Nationalbewußtsein herleiten.
