"Der Band vereinigt 20 Studien zu Nietzsche von Werner Stegmaier, der in den vergangenen drei Jahrzehnten der internationalen Nietzsche-Forschung starke Impulse gegeben und zuletzt achtzehn Jahre lang, zusammen mit Günter Abel, die Nietzsche-Studien, das international führende Organ der Nietzsche-Forschung, geleitet und die Monographien und Texte zur Nietzsche-Forschung herausgegeben hat. Die Studien handeln von Grundfragen der Philosophie Nietzsches. Sie setzen ein (I) mit seiner Neubestimmung der Wahrheit und der Philosophie und (II) seiner Verzeitlichung des Denkens unter (III) Verzicht auf ,die Vernunft' bei der Bestimmung des Menschen, interpretieren von hier aus (IV) die Anti-Lehren von Nietzsches Zarathustra, umreißen (V) Nietzsches Ethik für ,gute Europäer' und schließen (VI) mit der Interpretation von Nietzsches Selbsteinschätzung als Schicksal der Philosophie und der Menschheit (Ecce homo, Warum ich ein Schicksal bin 1) und einer Einschätzung von Nietzsches Zukunft, die schon seit über einem Jahrhundert begonnen hat. Werner Stegmaier, Jahrgang 1946, war Gründungsdirektor des Instituts für Philosophie der Universität Greifswald nach dem Zusammenbruch der Sowjetunion und baute das Nord- und osteuropäische Forum für Philosophie auf, das Institute für Philosophie rund um die Ostsee neu miteinander ins Gespräch brachte und dort zu philosophischen Neuorientierungen beitrug. Er hat auf vielfältigen Gebieten gearbeitet, unter anderem zur Metaphysik und ihrem Grundbegriff der Substanz, zu großen Philosophen von der Antike bis zur Gegenwart, zur philosophischen Aktualität der jüdischen Tradition, vor allem aber zur Philosophie Nietzsches. Dabei ging es ihm stets um Fragen der Ersten Philosophie, insbesondere die, was unsere Realität ausmacht, wie sie durch Zeichen und Kommunikation vermittelt wird, wie Begriffe in der Zeit existieren und womit man es beim Denken zu tun hat. Er führte den Begriff der Orientierung als elementaren Begriff der Philosophie ein und entwickelte eine umfassende Philosophie der Orientierung."--Publisher's website

The volume presents, in a synergistic manner, significant theoretical and practical contributions in the area of social media reputation and authorship measurement, visualization, and modeling. The book justifies and proposes contributions to a future agenda for understanding the requirements for making social media authorship more transparent. Building on work presented in a previous volume of this series, Roles, Trust, and Reputation in Social Media Knowledge Markets, this book discusses new tools, applications, services, and algorithms that are needed for authoring content in a real-time publishing world. These insights may help people who interact and create content through social media better assess their potential for knowledge creation. They may also assist in analyzing audience attitudes, perceptions, and behavior in informal social media or in formal organizational structures. In addition, the volume includes several chapters that analyze the higher order ethical, critical thinking, and philosophical principles that may be used to ground social media authorship. Together, the perspectives presented in this volume help us understand how social media content is created and how its impact can be evaluated. The chapters demonstrate thought leadership through new ways of constructing social media experiences and making traces of social interaction visible. Transparency in Social Media aims to help researchers and practitioners design services, tools, or methods of analysis that encourage a more transparent process of interaction and communication on social media. Knowing who has added what content and with what authority to a specific online social media project can help the user community better understand, evaluate and make decisions and, ultimately, act on the basis of such information

Most users on social media have intrinsic characteristics, such as interests and political views, that can be exploited to identify and track them, thus raising privacy and identity concerns in online communities. In this article, we investigate the problem of user identity linkage on two behavior datasets collected from different experiments. Specifically, we focus on user linkage based on users' interaction behaviors with respect to content topics. We propose an embedding method to model a topic as a vector in a latent space to interpret its deep semantics. Then a user is modeled as a vector based on his or her interactions with topics. The embedding representations of topics are learned by optimizing the joint-objective: the compatibility between topics with similar semantics, the discriminative abilities of topics to distinguish identities, and the consistency of the same user's characteristics from two datasets. The effectiveness of our method is verified on real-life datasets and the results show that it outperforms related methods. We also analyze failure cases in the application of our identity linkage method. Our analysis shows that factors such as the visibility and variance of user behaviors and users' group psychology can result in mis-linkages. We also analyze the details of the behaviors of some representative users to understand the essential reasons for their identity being mis-linked. We find that these users have high variance level in their behaviors. According to the above experimental results, we introduce a confidence score into identity linkage to provide information about the accuracy of the method results.

Geospatial data play a key role in a wide spectrum of critical data management applications, such as disaster and emergency management, environmental monitoring, land and city planning, and military operations, often requiring the coordination among diverse organizations, their data repositories, and users with different responsibilities. Although a variety of models and techniques are available to manage, access and share geospatial data, very little attention has been paid to addressing security concerns, such as access control, security and privacy policies, and the development of secure and in particular interoperable GIS applications. The objective of this paper is to discuss the technical challenges raised by the unique requirements of secure geospatial data management and to suggest a comprehensive framework for security and privacy for geospatial data and GIS. Such a framework is the first coherent architectural approach to the problem of security and privacy for geospatial data.

AbstractThis paper describes collaborative commerce (c‐commerce); it essentially combines e‐commerce, knowledge management and collaboration to carry out transactions and other activities within and across organizations. We first discuss the building blocks for c‐commerce. Then we describe models and federated architectures. Next we analyze the strategic role of knowledge management for c‐commerce as well as discussing managerial and business implications. Finally, we provide directions for c‐commerce.

O presente artigo busca analisar as relações tecidas entre o regime internacional de direitos humanos e o regime internacional relativo aos refugiados –ambos estruturados no contexto do pós-Segunda Guerra Mundial –, lançando luz, sobretudo, para a influência ocidental na construção da definição de refugiado cunhada pela Convenção Relativa ao Estatuto dos Refugiados de 1951. A proposta é ressaltar os termos notadamente marcados por uma perspectiva individualista e liberal dos direitos civis e políticos, a qual já estava presente na Declaração Universal dos Direitos Humanos de 1948, reverberando na elaboração da Convenção de 1951. Sustenta-se, nesse sentido, que a categorização da perseguição individualizada por motivos de nacionalidade, religião, raça, filiação a determinado grupo social ou opinião política privilegia direitos civis e políticos, tornando-os elementos centrais no regime internacional relativo aos refugiados – em detrimento a outros direitos reconhecidos como econômicos, sociais e culturais. A argumentação desenvolvida no texto se ampara em revisão bibliográfica da literatura especializada na área de estudos sobre refugiados, pesquisa documental sobre a Declaração Universal, a Convenção de 1951 e outros instrumentos jurídicos correlatos, além de artigos de relevância acadêmica e dados disponibilizados pela Organização das Nações Unidas.

Este artigo busca investigar a nova conjuntura do movimento feminista do Sul-Global, a qual poderia constituir uma mudança significativa no feminismo global – o Neofeminismo. Pretendemos investigar quais são as razões que fundamentam esta perspectiva, partindo da teoria pós-moderna. Os resultados apontam uma conjuntura essencialmente diferente das fases anteriores, na qual movimentos do Sul Global caminham em direção a uma atuação transnacional e anti-globalização. A partir de uma abordagem explicativa, a construção teórica foi baseada na revisão bibliográfica de livros e artigos relacionados ao tema.

6 págs.; 4 figs.; 1 tab. ; Rotationally mediated focused inelastic resonances (RMFIR's) in the angular distributions of D2 scattered from Cu(001) are observed. The FIR effect involves a phonon-assisted focusing of an incident beam of arbitrary energy and direction into a final channel of one single well-defined energy and direction. Surprisingly for an incident energy Ei = 27 meV the RMFIR conditions for the scattered beam coincide with the kinematic conditions required for a further elastic selective adsorption mechanism called the rotationally mediated critical kinematic (RMCK) effect. By taking advantage of the RMFIR and elastic RMCK effects, three effective bound states of energy ¿n,J = -21.5 meV, -12.4 meV, and -10.3 meV are determined. They are attributed to the lowest bound states ¿0 = -28.9 meV and ¿1 = -19.8 meV combined with the rotational excitation energy for J = 1 to be BrotJ(J + 1) = 7.41 meV, respectively, and ¿3 = -10.3 meV combined with the rotational ground state (J = 0). While the ¿1 and ¿3 states appear as maxima in the angular distribution at RMFIR conditions, the ¿0 yields a striking minimum which represents the first evidence of what we call an anti-FIR feature. Theoretical arguments to explain the different FIR signatures observed are provided. A fit of a phenomenological interaction potential to the experimental bound-state values yields a value for the well depth D = 32.5 meV which is somewhat deeper than that found previously. © 1997 The American Physical Society ; S.M.A. acknowledges the Alexander von Humboldt Stiftung for support.

O presente artigo se propõe a debater um novo conceito no campo de estudos migratórios – as migrações de crise –, o qual traz à luz os processos, motivos e fatores vivenciados por populações afetadas por crises e que podem contribuir para processos migratórios de indivíduos, famílias e comunidades como um todo. Introduzindo diversas categorias correlatas – como a eventualidade, a imobilidade (ou enclausuramento) e a não escolha –, adota-se um direcionamento metodológico e conceitual que aponta para as crises como propulsoras das migrações. Dessa maneira, busca-se tensionar a ideia de que as migrações geram crises aos Estados-nação receptores de movimentos significativos de pessoas – a qual notavelmente se consolida peladisseminação do termo "crise migratória", em especial, nos discursos políticos e midiáticos correntes. A delimitação do novo conceito proposto e da sua metodologia de estudo pautou-se pela revisão bibliográfica da literatura especializada na área, com foco em pesquisas recentes sobre as migrações de crise e suas implicações tanto na esfera local como na internacional. Ao final do texto, levantamos os desafios e as contribuições de tal conceito, envolvendo debates centrais no campo das migrações, inobstante questões teórico-metodológicas ainda não suficientemente superadas dentro deste.

Comunicació presentada a: AAAI Conference on Artificial Intelligence celebrat del 27 de gener a l'1 de febrer de 2019 a Hawaii, Estats Units d'Amèrica. ; In this paper we introduce an extension of context-free grammars called answer set grammars (ASGs). These grammars allow annotations on production rules, written in the language of Answer Set Programming (ASP), which can express context-sensitive constraints. We investigate the complexity of various classes of ASG with respect to two decision problems: deciding whether a given string belongs to the language of an ASG and deciding whether the language of an ASG is non-empty. Specifically, we show that the complexity of these decision problems can be lowered by restricting the subset of the ASP language used in the annotations. To aid the applicability of these grammars to computational problems that require context-sensitive parsers for partially known languages, we propose a learning task for inducing the annotations of an ASG. We characterise the complexity of this task and present an algorithm for solving it. An evaluation of a (prototype) implementation is also discussed. ; This research was sponsored by the U.S. Army Research Laboratory and the U.K. Ministry of Defence under Agreement Number W911NF-16-3-0001.

International audience ; Data about the regulatory approaches to donor human milk (DHM) in European countries are lacking. The aim of this study is to describe the various regulations of DHM within European countries, to assess its legislative context and its impact in relation to donor milk banking. We performed a cross-sectional survey using a semistructured online questionnaire addressing 29 national European milk-banking representatives from June 2020 to February 2021. Representatives of 26 national DHM services participated in this study. The legal classification and regulatory status of DHM were defined in 9 out of 26 areas of jurisdiction (35%) as either food product (n = 6), product of human origin according to a blood, tissue, cell regulation (n = 2), or medicinal product (n = 1). In the remainder, DHM remains unclassified. Most legislations did not provide a comprehensive framework concerning DHM and costs to cover milk bank operations were rarely reimbursed. In general, the lack of national legislative governance and the actual legislative regulations in place do not support the use of DHM in European countries. National medical guidelines for the use of DHM have been issued in only 11 countries. The current number and distribution of milk banks (n = 239) within participating countries may not provide an equitable access to DHM for eligible infants. These findings could guide stakeholders aiming to establish a regulatory framework for DHM.
