An effective formalism is developed to handle decaying two-state systems. Herewith, observables of such systems can be described by a single operator in the Heisenberg picture. This allows for using the usual framework in quantum information theory and, hence, to enlighten the quantum features of such systems compared to non-decaying systems. We apply it to systems in high energy physics, i.e. to oscillating meson–antimeson systems. In particular, we discuss the entropic Heisenberg uncertainty relation for observables measured at different times at (...) accelerator facilities including the effect of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\mathcal{CP}$\end{document} violation, i.e. the imbalance of matter and antimatter. An operator-form of Bell inequalities for systems in high energy physics is presented, i.e. a Bell-witness operator, which allows for simple analysis of unstable systems. (shrink)

Collapse models predict the spontaneous collapse of the wave function, in order to avoid the emergence of macroscopic superpositions. In their mass-dependent formulation, they claim that the collapse of any system’s wave function depends on its mass. Neutral K, D, B mesons are oscillating systems that are given by Nature as superposition of two distinct mass eigenstates. Thus they are unique laboratory for testing collapse models that are sensitive to the mass. In this paper we derive—for the single mesons and (...) bipartite entangled mesons—the effect of the mass-proportional CSL (Continuous Spontaneous Localization) collapse model on the dynamics on neutral mesons. We compare the theoretical prediction with experimental data from different accelerator facilities. (shrink)

Today, after the family, the school is the first institution in which children experience the implementation of social rules and the behaviors that follow from them. It is useful, therefore, to insert paths that favor the consolidation of a system made up of rules, inspired by the principles of transparency, fairness and solidarity, which can be the first and most effective lesson of democratic legality. In this perspective, teaching activities can appropriately refer to the programmatic contents of the disciplines which, (...) not only with regard specifically to civic education and law, but also with regard to other cultural areas, are bearers of explicit information and formative experiences. Particular attention is paid today to the planning of “Percorsi per le Competenze Trasversali e l’Orientamento” [Paths for Soft Skills and Guidance] (PCTO), which will also have an implicit educational value, that consisting in showing, through field experiences, the convergence of multiple cultural interests towards the purpose of education to legality.

Diesen Ausführungen liegt eine Auswahl von Leibniz' Briefen und Aufsätzen zugrunde‚ die sein Interesse an der Aufhebung der Zensur des kopernikanischen Systems bekunden. Die hier gesammelten Dokumente stammen aus den Jahren 1684 bis 1705 und enthalten Auszüge aus der Korrespondenz mit dem Landgrafen Ernst von Hessen-Rheinfels sowie Briefe und Memoranda von der italienischen Reise und Passagen aus dem Specimen Dynamicum und den Nouveaux Esseais. Im besonderen wird gezeigt, daß der von Louis Couturat als Vorrede zum Phoranomus herausgegebene Aufsatz als ein (...) vom Phoranomus unabhängiges Werk betrachtet werden muß.Ferner wird ein neuer Korrespondent von Leibniz als der italienische Jesuit Antonio Baldigiani identifiziert. Sodann wird die sogenannte „Zweite Bearbeitung“ vom Tentamen de Motuum Coelestium Causis datiert und es wird dargelegt‚ daß dieser Aufsatz im Rahmen der Auseinandersetzung Leibnizens mit der Zensur zu verstehen ist.

The purpose of this paper is to show the argument-establishing features of a Renaissance altarpiece. Looking to Panofsky’s seminal studies and to more recent contributions, this essay shows how in a special environment like the Florentine pre-Renaissance, people could easily relate to the evocative and contrastive potential of images. In the Santa Lucia de’ Magnoli Altarpiece painted by Domenico Veneziano we see an interesting dialogue between the main piece and the predella panels. This juxtaposition can be formalized into a (...) basic argumentative text. (shrink)

Despite the burgeoning literature on the governance and impact of cross-sector partnerships in the past two decades, the debate on how and when these collaborative arrangements address globally relevant problems and contribute to systemic change remains open. Building upon the notion of wicked problems and the literature on governing such wicked problems, this paper defines harnessing problems in multi-stakeholder partnerships as the approach of taking into account the nature of the problem and of organizing governance processes accordingly. The paper develops (...) an innovative analytical framework that conceptualizes MSPs in terms of three governance processes harnessing three key dimensions of wicked problems. The Roundtable on Sustainable Palm Oil provides an illustrative case study on how this analytical framework describes and explains organizational change in partnerships from a problem-based perspective. The framework can be used to better understand and predict the complex relationships between MSP governance processes, systemic change and societal problems, but also as a guiding tool in organizing governance processes to continuously re-assess the problems over time and address them accordingly.

Linking the process of rational decision making to emotions, an award-winning scientist who has done extensive research with brain-damaged patients notes the dependence of thought processes on feelings and the body's survival-oriented regulators. 50,000 first printing.

We characterize the collapse of Buss' bounded arithmetic in terms of the provable collapse of the polynomial time hierarchy. We include also some general model-theoretical investigations on fragments of bounded arithmetic.

This paper explores the relationship between business experience in cross-sector partnerships and the co-creation of what we refer to as ‘dynamic capabilities for stakeholder orientation,’ consisting of the four dimensions of sensing, interacting with, learning from and changing based on stakeholders. We argue that the co-creation of dynamic capabilities for stakeholder orientation is crucial for CSPs to create societal impact, as stakeholder-oriented organizations are more suited to deal with “wicked problems,” i.e., problems that are large, messy, and complex. By means (...) of a grounded theory approach of inductive research, we collected and interpreted data on four global agri-food companies which have heterogeneous experience in participating in CSPs. The results of this paper highlight that only companies’ capability of interacting with stakeholders continually increases, while their capabilities of sensing, learning from, and changing based on stakeholders first increase and then decrease as companies gain more experience in CSP participation. To a large extent, this can be attributed to the development of corporate strategies on sustainability after a few years of CSP participation, which entails a shift from a reactive to a proactive attitude towards sustainability issues and which may decrease the need or motivation for stakeholder orientation. These findings open up important issues for discussion and for future research on the impact of CSPs in a context of wicked problems. (shrink)

Legends and stories about fabulous races that dwelt in India or in Africa circulated in Iran probably since the Achaemenid times. Unfortunately, scholarship on this topic has neglected some late Iranian and, especially, Zoroastrian sources, such as Draxt ī āsūrīg, the Bundahišn, the Ayādgār ī Jāmāspīg, and the New Persian epic Šāhnāme. This article examines the aforementioned sources and discusses their accounts of five fabulous races from an Iranian, and especially Zoroastrian, perspective and through a comparative approach to some similar (...) neighboring traditions.

The relations between the Iranian, in particular Zoroastrian, and Jewish apocalyptic literature as well as their mutual influences have, since the beginning of the twentieth century, constituted a rich and exciting battlefield for the scholars of these respective traditions. This article aims to present some topics concerning the definition of Iranian apocalyptics and its relation with its Jewish counterpart, as well as to establish an updated starting point for a new scholarly debate.

We show that every model of IΔ0 has an end extension to a model of a theory where log-space computable function are formalizable. We also show the existence of an isomorphism between models of IΔ0 and models of linear arithmetic LA.

Perhaps no philosopher is more of a conundrum than Nietzsche, the solitary rebel, poet, wayfarer, anti-revolutionary Aufklärer and theorist of aristocratic radicalism. His accusers identify in his 'superman' the origins of Nazism, and thus issue an irrevocable condemnation; his defenders pursue a hermeneutics of innocence founded ultimately in allegory. In a work that constitutes the most important contribution to Nietzschean studies in recent decades, Domenico Losurdo instead pursues a less reductive strategy. Taking literally the ruthless implications of Nietzsche's anti-democratic (...) thinking - his celebration of slavery, of war and colonial expansion, and eugenics - he nevertheless refuses to treat these from the perspective of the mid-twentieth century. In doing so, he restores Nietzsche's works to their complex nineteenth-century context, and presents a more compelling account of the importance of Nietzsche as philosopher than can be expected from his many contemporary apologists.

In this paper we argue that data science is a coherent and novel approach to empirical problems that, in its most general form, does not build understanding about phenomena. Within the new type of mathematization at work in data science, mathematical methods are not selected because of any relevance for a problem at hand; mathematical methods are applied to a specific problem only by `forcing’, i.e. on the basis of their ability to reorganize the data for further analysis and the (...) intrinsic richness of their mathematical structure. In particular, we argue that deep learning neural networks are best understood within the context of forcing optimization methods. We finally explore the broader question of the appropriateness of data science methods in solving problems. We argue that this question should not be interpreted as a search for a correspondence between phenomena and specific solutions found by data science methods; rather, it is the internal structure of data science methods that is open to precise forms of understanding.

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)
