Domination is a structural complexity of chemical molecular graphs. A dominating set in a graphG=V,Eis a subsetS⊆Vsuch that each vertex inV\Sis adjacent to at least one vertex inS. The domination numberγGof a graphGis the minimum size of a dominating set inG. In this paper, computer-aided approaches for obtaining bounds for domination number on torus graphs are here considered, and many new exact values and bounds are obtained.

Boomerang employment has become an increasingly significant third way to obtain employees, yet little research has focused on why does ex-employee want to come back. Drawing from social identity theory, we propose that legacy identification could increase boomerang intention and both perceived corporate prestige and psychological contract violation could affect boomerang intention through legacy identification. The cooperative relationship between the former organization and the current organization could enhance these effects. Results from a two-time points survey of 202 Chinese employees showed (...) that legacy identification could increase boomerang intention, perceived corporate prestige could increase boomerang intention via legacy identification, psychological contract violation could decrease boomerang intention via legacy identification. Besides, the positive effect of legacy identification on boomerang intention, the positive indirect effect of corporate prestige on boomerang intention via legacy identification, and the negative indirect effect of psychological contract violation on boomerang intention via legacy identification are all stronger when there is a cooperative relationship. Theoretical and practical implications are discussed. (shrink)

Das weit uber die Zeit seiner Abfassung und uber die Grenzen seines Entstehungslandes hinaus unter dem Namen "Qabusname" bekannte, literarisch wie kulturgeschichtlich bedeutsame Werk heisst wortlich "Buch der Ratschlage," persisch "nasihat-name." Sein Verfasser Kej Kawus wurde um 1021/22 n.Chr. geboren und genoss die fur die persischen Furstensohne seit Jahrhunderten vorgeschriebene Erziehung, bei der eine Synthese von ritterlichen und geistigen, vornehmlich religiosen Tugenden angestrebt wurde. Es handelt sich um eines der interessantesten und eigenartigsten Erzeugnisse der mittelalterlichen iranischen Literatur. Mit Recht werden (...) der intime Ton des Werks und die reizvolle Schlichtheit der hubschen Anekdoten sowie die auf Schmuck verzichtende Einfachheit der Erzahlkunst geruhmt. Die vorliegende Ubersetzung des "Qabusname" ist die erste in deutscher Sprache, die nach dem persischen Original vorgenommen wurde. Die einzige fruhere deutsche Ubersetzung des Orientalisten H. F. von Diez erfolgte aus dem Turkischen und wurde 1811 veroffentlicht. Schon Goethe beschaftigte sich bei seiner Begegnung mit dem klassischen Schrifttum der Perser unter der Fuhrung H. F. von Diez eindringlich mit dem Qabusname. Der Beziehung des Dichters zu diesem so bedeutsamen Stuck der persischen Literatur ist daher ein besonderes Kapitel gewidmet. (shrink)

This volume explores the reorganisation of knowledge taking place in the course of Galileo's research process extending over a period of more than thirty years, pursued within a network of exchanges with his contemporaries, and documented by a vast collection of research notes. It has revealed the challenging objects that motivated and shaped Galileo's thinking and closely followed the knowledge reorganization engendered by theses challenges. It has thus turned out, for example, that the problem of reducing the properties of pendulum (...) motion to the laws governing naturally accelerated motion on inclined planes was the mainspring for the formation of Galileo's comprehensive theory of naturally accelerated motion.

How should we share the truth about the environmental crisis? At a moment when even the most basic facts about ecology and the climate face contestation and contempt, environmental advocates are at an impasse. Many have turned to social media and digital technologies to shift the tide-but what if their strategy is not only flawed, but dangerous? The Truth about Nature follows environmental actors as they turn to the internet to save nature. It documents how conservation efforts are transformed through (...) the political economy of platforms and the algorithmic feeds that have been instrumental to the rise of post-truth politics. Developing a novel account of post-truth as an expression of power under platform capitalism, Bram Büscher shows how environmental actors attempt to mediate between structural forms of platform power and the contingent histories and contexts of particular environmental issues. Bringing efforts at wildlife protection in Southern Africa into dialogue with a sweeping analysis of truth and power in the twenty-first century, Büscher makes the case for a new environmental politics: one that radically reignites the art of speaking truth to power.

Die Bildwissenschaft, so scheint es, steckt in einer Sackgasse: Teile von ihr sind zur antiaufklärerischen Ideologie geworden, die Interpreten erlaubt, autoritäre Positionen der Auslegung als Macht des Bildes zu beschreiben. Zeit, sie vom Kopf auf die Füsse zu stellen. Um dies einzulösen, rekonstruiert Martin Büchsel akribisch die wichtigsten bildwissenschaftlichen Theorien der letzten Jahrzehnte inklusive ihrer impliziten Ideologien und Mythen und kontrastiert diese mit aufklärerischen Positionen. Dabei bezieht die sorgsam ausgearbeitete Monographie alle international relevanten Theoretiker und Theorien in seine Überlegungen mit (...) ein. Geleistet wird eine fundamentale Kritik der Bildwissenschaften, gleichermassen kann das Buch aber auch als vertiefende Einführung in dieselben dienen. Womit das Potenzial dieser Studie noch keineswegs ausgeschöpft ist: In einem zweiten Teil entwirft Büchsel Eckpfeiler einer zukünftigen, vorstellungskritischen Bildwissenschaft, die Philosophie, Philologie und Kunstgeschichte höchst produktiv miteinander ins Gespräch bringt.

'Symbolizing existence' deals with the current rapidly happening deterritorialization of everything which was once regarded stable and binding. What we today regard as statistically encoded information is capable to explicate and index the entire realm of what can be expressed and represented through a cascade of geometrical, functional, or finally logified schemes. We are currently experiencing a rapid loss of grounding of that which we once considered binding in our cultural and intellectual history. How can we obtain an articulate, cultivate (...) way of thinking about instances that does not fall back into a schematic model Platonism (thereby falling behind Plato), and that does not remain enmeshed in an Aristotelian realization dynamics with a naturalism organized by original genus, kinds, and specific marks of distinction? The central phenomenon considered was the technological process of doping material: At the quantum level, a particle or its representation, the point, is no longer "that which has no parts" (Euclid).

This study combined conservation of resources theory with the job demands-resources model to explore the influence of leader mindfulness on the emotional exhaustion of university teachers Using a time-lagged research design, 388 paired data sets were gathered. Multiple regression and bootstrapping were used to test each hypothesis. The results showed that first, leader mindfulness significantly reduces the emotional exhaustion of university teachers. Second, the results showed that workplace telepressure partially mediates the relationship between leader mindfulness and the emotional exhaustion of (...) university teachers. Third, university teacher mindfulness positively moderates the relationship between leader mindfulness and workplace telepressure. Finally, the results of this study indicate that self-efficacy in managing negative emotions negatively moderates the relationship between workplace telepressure and the emotional exhaustion of university teachers. This study empirically examined the interpersonal influence of leader mindfulness and the initial resources effect of university teacher mindfulness and self-efficacy in managing negative emotions from the bilateral perspective of leaders and university teachers.
