The exploration of chemical periodicity over the past 250 years led to the development of the Periodic System of Elements and demonstrates the value of vague ideas that ignored early scientific anomalies and instead allowed for extended periods of normal science where new methodologies and concepts are developed. The basic chemical element provides this exploration with direction and explanation and has shown to be a central and historically adaptable concept for a theory of matter far from the reductionist frontier. This (...) is explored in the histories of Prout’s hypothesis, Döbereiner Triads, element inversions necessary when ordering chemical elements by atomic weights, and van den Broeck’s ad-hoc proposal to switch to nuclear charges instead. The development of more accurate methods to determine atomic weights, Rayleigh and Ramsey’s gas separation and analytical techniques, Moseley’s X-ray spectroscopy to identify chemical elements, and more recent accelerator-based cold fusion methods to create new elements at the end of the Periodic Table point to the importance of methodological development complementing conceptual advances. I propose to frame the crossover from physics to chemistry not as a loss of accuracy and precision but as an increased application of vague concepts such as similarity which permit classification. This approach provides epistemic flexibility to adapt to scientific anomalies and the continued growth of chemical compound space and rejects the Procrustean philosophy of reductionist physics. Furthermore, it establishes chemistry with its explanatory and operational autonomy epitomized by the periodic system of elements as a gateway to other experimental sciences. (shrink)

Angesichts der Globalisierung und der von ihr aufgeworfenen Probleme für das nationale und das internationale Recht gewinnt die Rechtsphilosophie immer stärker an Bedeutung. Zugleich verbinden sich rechtstheoretische Fragen wieder zunehmend mit philosophischen Überlegungen. Der vorliegende Band versammelt 20 Beiträge namhafter Rechtstheoretiker und Philosophen, die die eigenständige Begriffsbildung und die Entwicklung neuer Theorieansätze auf dem Gebiet der Rechtsphilosophie zum Ziel haben. Das Spektrum reicht dabei von grundbegrifflichen Klärungen bis hin zu konkreten Problemstellungen des globalisierten Rechts und bietet einen umfassenden Überblick über (...) die aktuelle deutsche und internationale Debatte. Mit Beiträgen u. a. von Robert Alexy, Klaus Günther, Gunther Teubner, Otfried Höffe und Jürgen Habermas. (shrink)

Why are negative emotions so central in art reception far beyond tragedy? Revisiting classical aesthetics in the light of recent psychological research, we present a novel model to explain this much discussed (apparent) paradox. We argue that negative emotions are an important resource for the arts in general, rather than a special license for exceptional art forms only. The underlying rationale is that negative emotions have been shown to be particularly powerful in securing attention, intense emotional involvement, and high memorability, (...) and hence is precisely what artworks strive for. Two groups of processing mechanisms are identified that conjointly adopt the particular powers of negative emotions for art's purposes. The first group consists of psychological distancing mechanisms that are activated along with the cognitive schemata of art, representation, and fiction. These schemata imply personal safety and control over continuing or discontinuing exposure to artworks, thereby preventing negative emotions from becoming outright incompatible with expectations of enjoyment. This distancing sets the stage for a second group of processing components that allow art recipients to positively embrace the experiencing of negative emotions, thereby rendering art reception more intense, more interesting, more emotionally moving, more profound, and occasionally even more beautiful. These components include compositional interplays of positiveandnegative emotions, the effects of aesthetic virtues of using the media of (re)presentation (musical sound, words/language, color, shapes) on emotion perception, and meaning-making efforts. Moreover, our Distancing-Embracing model proposes that concomitant mixed emotions often help integrate negative emotions into altogether pleasurable trajectories. (shrink)

This article examines rival strategies employed by public, private and civil society actors to promote fair trade organic commodity chains. The article analyses the case of fair trade organic cotton as a produce that is on the brink of reaching a mass market, and compares this with patterns of the more widely documented fair trade organic fruit case. It is shown how variations in commodity chain configurations and interfaces reflect different stakeholder positions and interests, as well as development philosophies. The (...) case of fair trade organic cotton chains illustrates how stakeholder involvement may speed up learning and thus facilitate mass-market entry. Finally, it is argued that rival commodity chain configurations make it difficult to agree upon common fair trade organic cotton certification strategies. (shrink)

Microscopy allows us to observe objects we cannot see with our eyes alone. With a light microscope, we can distinguish objects at the scale of the wavelengths of visible light just under a micrometer. Around 1870 Ernst Abbe, who laid the foundation of modern optics, suggested that the resolution of a microscope would improve by using some yet-unknown radiation with shorter wavelengths than visible light, that is, below 390 nanometers (1 nm = 10−9 m). Electrons can have wavelengths near 1 (...) picometer (1 pm = 10−12 m) and should therefore allow atoms to be distinguished since they are typically at least a few hundred pm apart. In this oversimplified view, further decreasing the wavelength of the radiation should allow us to increase the resolution of electron microscopy even more. However, this can only be done by increasing the energy of the radiation, which would ultimately destroy the samples. Other factors also affect the resolution of electron microscopes, among them non-ideal imaging properties of electromagnetic lenses, which result in false images. It took more than half a century to understand and control these aberrations and separate objects less than 1 Ångstrom (1 Å = 10−10 m) apart. (shrink)

Nicht nur die Politik, auch die Demokratietheorie thematisiert die Partizipation der Bürger seit Jahren vorwiegend unter dem Gesichtspunkt der Rationalität. Demgegenüber diskutiert der vorliegende Band, ausgehend vom Denken Hannah Arendts, wie sich demokratische Politik noch als Praxis, d.h. als ein um seiner selbst willen geschätztes Handeln unter Freien und Gleichen denken lässt.
