We revisit the notion of deniability in quantum key exchange (QKE), a topic that remains largely unexplored. In the only work on this subject by Donald Beaver, it is argued that QKE is not necessarily deniable due to an eavesdropping attack that limits key equivocation. We provide more insight into the nature of this attack and how it extends to other constructions such as QKE obtained from uncloneable encryption. We then adopt the framework for quantum authenticated key exchange, developed by Mosca et al., and extend it to introduce the notion of coercer-deniable QKE, formalized in terms of the indistinguishability of real and fake coercer views. Next, we apply results from a recent work by Arrazola and Scarani on covert quantum communication to establish a connection between covert QKE and deniability. We propose DC-QKE, a simple deniable covert QKE protocol, and prove its deniability via a reduction to the security of covert QKE. Finally, we consider how entanglement distillation can be used to enable information-theoretically deniable protocols for QKE and tasks beyond key exchange. [less ▲]

The finite-time attitude synchronization problem is considered in this paper, where the rotation of each rigid body is expressed using the axis-angle representation. Two discontinuous and distributed controllers using the vectorized signum function are proposed, which guarantee almost global and local convergence, respectively. Filippov solutions and non-smooth analysis techniques are adopted to handle the discontinuities. Sufficient conditions are provided to guarantee finite-time convergence and boundedness of the solutions. Simulation examples are provided to verify the performances of the control protocols designed in this paper. [less ▲]

An indicator of pro-poorness of a growth profile associated with a distribution of income is a measure of the extent to which growth is biased towards the poor. This paper proposes a general approach to pro-poorness, called the progressive sequential averaging principle (PSA), relaxing the requirement of rank preservation due to growth. An endogenous benchmark for evaluating the growth of poor comes out naturally from this principle. A dominance relation on the basis of the above approach for a class of growth profiles is introduced through a simple device, called the PSA curve and its properties are examined in relation to the standard dominances in terms of the generalized Lorenz curve and the inverse generalized Lorenz curve. The paper concludes with an application to evaluate growth profiles experienced by the United States between 2001-2007 and 2007-2013. [less ▲]

Mutation analysis is a well-studied, fault-based testing technique. It requires testers to design tests based on a set of artificial defects. The defects help in performing testing activities by measuring the ratio that is revealed by the candidate tests. Unfortunately, applying mutation to real-world programs requires automated tools due to the vast number of defects involved. In such a case, the effectiveness of the method strongly depends on the peculiarities of the employed tools. Thus, when using automated tools, their implementation inadequacies can lead to inaccurate results. To deal with this issue, we cross-evaluate four mutation testing tools for Java, namely PIT, muJava, Major and the research version of PIT, PITRV, with respect to their fault-detection capabilities. We investigate the strengths of the tools based on: a) a set of real faults and b) manual analysis of the mutants they introduce. We find that there are large differences between the tools’ effectiveness and demonstrate that no tool is able to subsume the others. We also provide results indicating the application cost of the method. Overall, we find that PITRV achieves the best results. In particular, PITRV outperforms the other tools by finding 6% more faults than the other tools combined. [less ▲]

This chapter explores how time and temporality – that is, the rhythms and tempos of social and environmental change – have been considered in social theory before going on to explore the conceptual frameworks and practices through which policy-makers seek to influence temporal processes in the specific context of climate change policy. The chapter highlights conflict between the temporalities of climate change and the temporalities of politics, as well as conflict between the temporalities of competing political and decision-making processes. While policy-makers advocate strategies to depoliticize climate policy in response to these conflicts, the chapter argues this is neither possible nor desirable. Instead, it advocates more democratic and deliberative approaches to the challenge of synchronizing ever more visible ecological temporalities with the multiple temporalities of the social. [less ▲]

Objective: Impulsivity is a multifaceted construct known to play a crucial role in the development and maintenance of a wide range of problematic behaviors and psychological disorders in children. Method: In this study, we adapted the short French adult version of the UPPS-P Impulsive Behavior Scale for use with children (short UPPS-P-C) and tested its psychometric properties. Results: Confirmatory factor analyses conducted on a sample of 425 children (aged from 8 to 14 years) supported the five-factor structure of the scale. Additional analyses emphasized the good internal and test-retest reliability of the short UPPS-P-C. Furthermore, our results also revealed that lack of premeditation and urgency subscales were able to discriminate between children diagnosed with attention-deficit/hyperactivity disorder (ADHD) and their matched controls. Conclusion: These results suggest that the short UPPS-P-C may be considered as a promising time-saving tool to assess impulsivity traits in healthy children and in children with psychiatric disorders.

countries. It views educational institutions as a key producer of social cohesion by supplying the shared beliefs that generate shared cultural meanings. To most institutionalists, education (schools, colleges, universities, but also home schooling, religious, and informal education) stands out as one of only a handful of key social institutions next to the family, the economy, religion, science, and government. Higher education takes its place in this nexus of institutions, as it globally expands in size and grows in strategic importance. [less ▲]

Tax Treaty dispute resolution through the Mutual Assistance Procedure (MAP) is particularly relevant in Luxembourg. Luxembourg has, as of May 2018, 81 Double Tax Convention (henceforth, “DTC”) out of which only 12 provide for arbitration clauses. In contrast, while the Arbitration procedure is also available, it is barely used in practice as the MAP procedure proves to be the most common form of resolution of tax treaty dispute resolutions in Luxembourg.

Jugendliche aus stationären Einrichtungen (z.B. Heime) sind häufig von der Chronifizierung einer psychischen Störung bedroht [Schmid, 2007]. Unter anderem aufgrund von Traumatisierungen sind externalisierende Verhaltensprobleme, z.B. wiederholter unangemessener Ärgerausdruck, festzustellen, die einen Behandlungserfolg in Frage stellen. Erforderlich ist es daher problematische Ärgerreaktionen von Jugendlichen zu thematisieren, und den Umgang mit Ärger zu verändern. In dieser Falldarstellung wird die Umsetzung eines 10-wöchigen kognitiv-verhaltenstherapeutischen Ärgerbewältigungstrainings [Schwenkmezger et al., 1999] bei einem fremdplatzierten verhaltensauffälligen Jugendlichen aufgezeigt [Steffgen et al., 2014]. Die eingesetzten testdiagnostischen Verfahren belegen, dass die Bereitschaft zu aggressiven Verhaltensweisen sowie des nach außen gerichteten Ärgerausdrucks reduziert, und die Ärgerkontrolle erhöht wurde. Insgesamt konnte die Wirksamkeit der programmgestützten Intervention am Einzelfall nachgewiesen werden. Jugendliche in der Heimunterbringung können somit durch die Teilnahme an einer Ärgerintervention Nutzen ziehen, indem sie lernen ihre Emotionsregulation zu optimieren, um dadurch ihre soziale Kompetenz zu erhöhen. Ihre gesellschaftliche Eingliederung ließe sich dadurch erleichtern. [less ▲]

Die hohe und gestiegene Bedeutung inklusiver Bildung – für Individuen und Gesellschaften gleichermaßen – wird global, national, regional und lokal von verschiedensten Akteur*innen hervorgehoben sowie zunehmend auch wissenschaftlich multidisziplinär diskutiert. Fragen der Steuerung, der Governance, hingegen, sind bisher im deutschsprachigen Raum nur wenig systematisch oder umfassend analysiert worden, obwohl mehrere Wissenschaftsdisziplinen sich zunehmend mit diesen Fragen auseinandersetzen. Während politikwissenschaftliche Analysen die Machtstrukturen, Pfadabhängigkeiten und Entscheidungsprozesse fokussieren haben soziologische Analysen die globale Diffusion von Diskursen und Normen sowie systembedingte Komplexitäten und Umsetzungsschwierigkeiten vielfältiger Reformen verdeutlicht. Die Erziehungswissenschaft, nicht nur in der deutsch-sprachigen Welt, hat sich lange Zeit schwer getan, sich eindeutig zu den brisanten bildungs- als auch sozialpolitischen Fragen der inklusiven Bildung – auch die zentrale Frage der Governance – zu positionieren, weil es das fundamentale Verhältnis von Allgemeiner und Sonderpädagogik hinterfragt sowie in letzter Konsequenz die Transformation des gegliederten und hochgradig selektiven Bildungswesen verlangt. Dieser Band beleuchtet eben dieses Spannungsverhältnis aus verschiedenen Perspektiven; in diesem Beitrag wird deshalb versucht, verschiedene Dimensionen der Governance auf der Forschungsagenda zu platzieren, wie auch in zwei konkreten Fällen – Deutschland und Luxemburg – zu vertiefen.

Over the past decade, a flourishing number of concepts and architectural shifts appeared such as Industrial Internet of Things (IIoT), Industrial CPS or even Industry 4.0. Unfortunately, today’s IoT as well as Industry 4.0 environments, look more like a collection of isolated “Intranets of Things”, also referred to as “vertical silos”, rather than a federated infrastructure. Breaking down these silos is a key challenge in both the IoT and Industry 4.0 communities. This paper is intended to present and discuss two open and standardised mes- saging protocols designed for IoT applications, namely: MQTT and O-MI/O-DF. First, a traffic load’s analytical model derived from the MQTT standard specifications is presented. Second, a comparison study between MQTT and O-MI/O-DF standards is carried out based on a real-life industrial implementation. This study brings a deep understanding of the extent to which these protocols are performant (from a traffic load perspective) and how they can impact on future architectural designs. [less ▲]
