River flows and profit flows: the powerful logic driving local news

The importance of local news is gaining traction with industry and in journalism scholarship. But there is a need for careful analysis of what it means to be “local” and how we might theorise the role and place of news organisations and journalists who serve local audiences. This paper draws on three qualitative case studies of local newspapers serving small towns and cities in Australia to generate concepts that can be used to deepen understanding about this form of news. Our research highlights that to be local is practical and embodied. It requires individuals, groups, organisations or institution to be anchored in a particular locale and have in-depth understanding of that place that has developed over time. We extend the scholarship of Pierre Bourdieu to suggest this may be understood as local habitus—a powerful set of dispositions and practical logic developed within a place—that the small newspaper is inherently tied to. Reading a newspaper is part of one's local habitus while an individual who possesses it in the journalistic field may have a significant advantage in their day-to-day practices. We suggest this theoretical lens can offer rich insights into the future of local news production across the western world.

El dialogo Socratico como razonamiento colegiado

Thinking with clarity and avoiding contradictions are some of the contributions of philosophy to bioethics, politics or the public sector.  Through philosophical practice, some of the subjects generally treated in educational contexts are now applied within the world of industry or the private company.  Thus, Socratic Dialogue turns into a very powerful tool to reveal deeper levels of group decision making.  The author explains the steps of this particular appraoch and how this methodology works in reality using an example of his personal practice.

"Everything was designed to make sure that this thing endured" : Processus de légitimation et la Responsabilité de protéger

L’objet de cette thèse est la « Responsabilité de protéger » (RdP), son émergence et les processus de légitimation qui ont contribué à son acceptation dans les arènes de la politique globale. Le principe d’une intervention militaire à des fins humanitaires gagne en légitimité dans les années 1990, bien qu’il soit marqué par d’intenses polémiques dans la pratique. Les situations de conflits où les civils sont brutalement persécutés et les interventions demandées et organisées pour y répondre sont maintenant largement justifiées dans les termes de la RdP. Est donc apparu d’abord un changement normatif. Ce changement s’est cristallisé dans le rapport de la Commission internationale sur l’intervention et la souveraineté des États (CIISE) qui a forgé l’expression « responsabilité de protéger ». Le point de départ ici est cependant que la RdP marque un changement discursif dans la manière de parler et de justifier ces pratiques. Je montre comment les termes de la RdP en sont venus à être ceux qui dégagent le plus large consensus autour de la question de l’intervention à des fins humanitaires. La thèse centrale de cette recherche est que le relatif succès de la RdP tient au fait que les architectes de la CIISE et les entrepreneurs de la RdP ont déployé un sens pratique aiguisé du champ de la politique globale. Le procédé principal employé est de mettre en lumière les processus de légitimation activement mis en oeuvre pour stimuler ce changement discursif. J’avance que les agents ont su placer la RdP, et par extension le principe de l’intervention à des fins humanitaires, dans le domaine du non problématique en déployant un langage et des pratiques vus comme ne posant pas problème. Concrètement, il s’est agi de choisir les agents à qui serait accordée la reconnaissance de parler, mais qui seraient aussi en mesure de proposer une solution d’une manière considérée comme légitime dans les arènes de la politique globale. Traquer les processus de légitimation est un procédé analytique qui permet de comprendre le succès de la RdP, mais qui révèle également des éléments fondamentaux du fonctionnement formel et informel de la politique globale.

Medienvermittelte transnationale Öffentlichkeiten im Zeitalter praktischer Hybridisierung (English title: Mediated transnational publics in environments of practical hybridisation)

This article is concerned with the repercussions of societal change on transnational media. It offers a new understanding of multilingual programming strategies by examining “Radio MultiKulti” (RM), a public service radio station discontinued from 1/1/2009 by Rundfunk Berlin-Brandenburg. In its fourteen years of existence, “RM” had to implement a well-intended and politically-motivated logic of ‘multiethnic, intercultural service station’. However, as we demonstrate, such a direction, despite some achievements, has resulted in the constraints to RM’s journalistic activities and language policy, drawing criticism for the station’s economic viability. This paper proposes that multilingual media services are to be framed by the concept of practical hybridity that allows a necessary responsiveness towards an ever-changing media environment, at the moment within digital culture. Our approach draws on Mikhail Bakhtin’s and Yuri Lotman’s theoretical approaches to hybridity, as well as in-depth interviews conducted with “RM” staff from 2005 onwards, further interviews with key agents outside RM and a continuous monitoring of the public debate which culminated at the end of 2008 in the controversial decision to close the radio station. Against this background, the concluding remarks are meant to contribute to the scholarly debate on hybridization as well as to inform multilingual media policy in the 21st century.

Purposeful program theory: Effective use of theories of change and logic models [Book Review]

The purpose of this book by two Australian authors is to: introduce the audience to the full complement of contextual elements found within program theory; offer practical suggestions to engage with theories of change, theories of action and logic models; and provide substantial evidence for this approach through scholarly literature, practice case studies together with the authors' combined experience of 60 years.

Dependence Logic: Investigations into Higher-Order Semantics Defined on Teams

This thesis is a study of a rather new logic called dependence logic and its closure under classical negation, team logic. In this thesis, dependence logic is investigated from several aspects. Some rules are presented for quantifier swapping in dependence logic and team logic. Such rules are among the basic tools one must be familiar with in order to gain the required intuition for using the logic for practical purposes. The thesis compares Ehrenfeucht-Fraïssé (EF) games of first order logic and dependence logic and defines a third EF game that characterises a mixed case where first order formulas are measured in the formula rank of dependence logic. The thesis contains detailed proofs of several translations between dependence logic, team logic, second order logic and its existential fragment. Translations are useful for showing relationships between the expressive powers of logics. Also, by inspecting the form of the translated formulas, one can see how an aspect of one logic can be expressed in the other logic. The thesis makes preliminary investigations into proof theory of dependence logic. Attempts focus on finding a complete proof system for a modest yet nontrivial fragment of dependence logic. A key problem is identified and addressed in adapting a known proof system of classical propositional logic to become a proof system for the fragment, namely that the rule of contraction is needed but is unsound in its unrestricted form. A proof system is suggested for the fragment and its completeness conjectured. Finally, the thesis investigates the very foundation of dependence logic. An alternative semantics called 1-semantics is suggested for the syntax of dependence logic. There are several key differences between 1-semantics and other semantics of dependence logic. 1-semantics is derived from first order semantics by a natural type shift. Therefore 1-semantics reflects an established semantics in a coherent manner. Negation in 1-semantics is a semantic operation and satisfies the law of excluded middle. A translation is provided from unrestricted formulas of existential second order logic into 1-semantics. Also game theoretic semantics are considerd in the light of 1-semantics.

Rethinking Service Companies’ Business Logic: Do We Need a Customer-Dominant Logic as a Guideline?

Purpose –This paper explores and expands the roles of customers and companies in creating value by introducing a new a customer-based approach to service. The customer’s logic is examined as being the foundation of a customer-based marketing and business logic. Design/methodology/approach – The authors argue that both goods-dominant logics and service-dominant logics are provider-dominant. Contrasting the customer-dominant logic with provider-dominant logics, the paper examines the creation of service value from the perspectives of value-in-use, the customer’s own context, and the customer’s experience of service. Findings –Moving from a provider-dominant logic to a customer-dominant logic uncovered five major challenges to service marketers: Company involvement, company control in co-creation, visibility of value creation, locus of customer experience, and character of customer experience. Research limitations/implications – The paper is exploratory. It presents and discusses a conceptual model and suggests implications for research and practice. Practical implications –Awareness of the mechanisms of customer logic will provide businesses with new perspectives on the role of the company in their customer’s lives. We propose that understanding the customer’s logic should represent the starting-point for the marketer’s business logic. Originality/value – The paper increases the understanding of how the customer’s logic underpins the customer-dominant business logic. By exploring consequences of applying a customer-dominant logic, we suggest further directions for theoretical and empirical research.

Tailoring Plasmonic Metamaterials for DNA Molecular Logic Gates

Structural and functional information encoded in DNA combined with unique properties of nanomaterials could be of use for the construction of novel biocomputational circuits and intelligent biomedical nanodevices. However, at present their practical applications are still limited by either low reproducibility of fabrication, modest sensitivity, or complicated handling procedures. Here, we demonstrate the construction of label-free and switchable molecular logic gates that use specific conformation modulation of a guanine- and thymine- rich DNA, while the optical readout is enabled by the tunable alphabetical metamaterials, which serve as a substrate for surface enhanced Raman spectroscopy (MetaSERS). By computational and experimental investigations, we present a comprehensive solution to tailor the plasmonic responses of MetaSERS with respect to the metamaterial geometry, excitation energy, and polarization. Our tunable MetaSERS-based DNA logic is simple to operate, highly reproducible, and can be stimulated by ultra-low concentration of the external inputs, enabling an extremely sensitive detection of mercury ions.

Tools for Finding Inconsistencies in Real-world Logic-based Systems

Currently there is extensive theoretical work on inconsistencies in logic-based systems. Recently, algorithms for identifying inconsistent clauses in a single conjunctive formula have demonstrated that practical application of this work is possible. However, these algorithms have not been extended for full knowledge base systems and have not been applied to real-world knowledge. To address these issues, we propose a new algorithm for finding the inconsistencies in a knowledge base using existing algorithms for finding inconsistent clauses in a formula. An implementation of this algorithm is then presented as an automated tool for finding inconsistencies in a knowledge base and measuring the inconsistency of formulae. Finally, we look at a case study of a network security rule set for exploit detection (QRadar) and suggest how these automated tools can be applied.

Tailoring Plasmonic Metamaterials for Ultrasenstive Detection of Mercury Trace Contaminants via Molecular Logic Gates

Structural and functional information encoded in DNA combined with unique properties of nanomaterials could be of use for the construction of novel biocomputational circuits and intelligent biomedical nanodevices. However, at present their practical applications are still limited by either low reproducibility of fabrication, modest sensitivity, or complicated handling procedures. Here, we demonstrate the construction of label-free and switchable molecular logic gates (AND, INHIBIT, and OR) that use specific conformation modulation of a guanine- and thymine-rich DNA, while the optical readout is enabled by the tunable metamaterials which serve as a substrate for surface enhanced Raman spectroscopy (MetaSERS). Our MetaSERS-based DNA logic is simple to operate, highly reproducible, and can be stimulated by ultra-low concentration of the external inputs, enabling an extremely sensitive detection of mercury ions down to 2×10-4 ppb, which is four orders of magnitude lower than the exposure limit allowed by United States Environmental Protection Agency
