description: The interplay between the quasi 1-dimensional CuO-chains and the 2-dimensional CuO2 planes of YBa2Cu3O6+x (YBCO) has been in focus for a long time. Although the CuO-chains are known to be important as charge reservoirs that enable superconductivity for a range of oxygen doping levels in YBCO, the understanding of the dynamics of its temperature-driven metal-superconductor transition (MST) remains a challenge. We present a combined study using x-ray absorption spectroscopy and resonant inelastic x-ray scattering (RIXS) revealing how a reconstruction of the apical O(4)-derived interplanar orbitals during the MST of optimally doped YBCO leads to substantial hole-transfer from the chains into the planes, i.e. self-doping. Our ionic model calculations show that localized divalent charge-transfer configurations are expected to be abundant in the chains of YBCO. While these indeed appear in the RIXS spectra from YBCO in the normal, metallic, state, they are largely suppressed in the superconducting state and, instead, signatures of Cu trivalent charge-transfer configurations in the planes become enhanced. In the quest for understanding the fundamental mechanism for high-Tc-superconductivity (HTSC) in perovskite cuprate materials, the observation of such an interplanar self-doping process in YBCO opens a unique novel channel for studying the dynamics of HTSC.

description: The purpose of this study was to explore the junior to senior transition from professional contract to an established first-team player in an English men’s professional football team. Six players were purposively sampled across four suggested phases of transition: preparation; orientation; adaptation; and stabilization . A series of three interviews explored their past and current experiences, as well as their future ambitions. Eight higher-order themes were developed using thematic analysis: performance culture; opportunity; organizational strategy; contracts; relationships; motivation; power dynamics; and dual career. Several general adaptation factors found in previous research were present, along with four unique findings. The current study sets the opportunity to play within the first team as the primary factor in career progression. Without the opportunity, a “gray period” develops when a player is in an undefined phase without specific goals. This complex transition is further complicated by the short-term nature of contracts, which influences motivation and the ability to see the big picture. Throughout the transition, receiving support from key stakeholders was challenged by their role as gatekeepers of playing time and future contracts. Organizations should seek to manage transitions through a hands-on approach, providing the necessary support throughout the gray period, while being aware of the limitations of support from those with power over opportunity. Future research should look to explore the suggested gray period and the challenges that develop without continual opportunity. Lay summary: Professional football players at different stages in their career discussed the challenges experienced in their journey to becoming a regular first-team player. Those players that were not getting the opportunity to play felt isolated and unable to discuss their concerns. Implications for football clubs managing this transition are discussed.IMPLICATIONS FOR PRACTICEProviding opportunity in the senior team while managing players with no opportunityAvailability and awareness of support systems outside of decision-makers Providing opportunity in the senior team while managing players with no opportunity Availability and awareness of support systems outside of decision-makers

Um princípio que foi esquecido no império da Cristandade e que foi corrompido pela revolução das luzes,mas que foi recuperado na ordem social contemporânea dos estados de Direito. A fundamentação ética da ordem política democrática atual assenta nesta ideiade que as religiões são concretizações históricas e relativas da universal e absoluta verdade divina.

description: Future aircraft design may require the use of laminar wing in order achieve the targets for emission reduction set by the ACARE Vision 2020 and FlightPath 2050 strategies for future air transport. The integration of high lift system for laminar wing remains one of the main challenges in the field. Classical high lift configuration using slat devices are proscribed with laminar wing due to the introduction of turbulence into the flow over the upper side of the wing. In addition, there is a need to shield the leading edge of the wing during low altitude flight where pollution and insect could adversely impact the laminarity of the main wing for cruise conditions [1]. The Unsteady High-lift Aerodynamics Unsteady RANS Validation project (UHURA) investigates a Krueger flap leading edge devices both experimentally and numerically. The Krueger is represented by an additional lift surface concept that is deployed during the flight from the lower side of the wing for take-off and landing [2]. The concept of the Krueger was initiated in the 1940s [3] and was first found to be promising high-lift system for laminar wing technology during the NASA B757 laminar wing flight test program [4]. However, due to its complexity and the potential development of critical unsteadiness within the flow during the deployment, the classical slat device was preferred by aircraft manufacturer [1] and was highly investigated in the literature [5, 6]. Today, the Krueger devices capability to shield the leading edge of the wing during take and its promising performances makes it a suitable candidate for laminar wing device. Within the UHURA project, a recent wind tunnel test campaign was conducted at the ONERA L1 wind tunnel [7] using the DLR-F15 [8] Airfoil model that features a full span Krueger device, which can be actuated at high deflection rates up to 180/s. The tests include the measurements steady and unsteady static pressure as well as phase-locked Particle Image Velocimetry (PIV) on the lower section of the wing. The high spatial resolution synchronous measurement permits a detailed assessment of the flow velocity and unsteadiness to provide a first step in understanding the dynamic flow field during the Krueger deployment and retraction phases. The high number of static pressure measurements will allow to calculate the variation of aerodynamic forces over the Krueger during multiple cycles. The impact of the deployment speed and flow velocity will also be investigated.

Consider a commutative linear algebraic group G=G_m^r\times G_a. We study equivariant G-embeddings, i.e. normal G-varieties X containing G as an open orbit. We prove that X is a toric variety and all such actions of G on X correspond to Demazure roots of the fan of X. In these terms, the orbit structure of a G-variety X is described.

description: Network operators spend significant effort in ensuring that the network meets their intended policies. While recent work on checking reachability and isolation policies have taken giant strides in this regard, they do not handle context-dependent policies that operators implement via stateful data plane elements. To address this challenge, we present the design and implementation of BUZZ, a testing framework to ensure that a network with stateful data plane elements meets complex context-dependent policies. In designing BUZZ, we address significant challenges in: (1) modeling stateful data plane elements, and (2) tackling the state-space explosion problem in generating test scenarios. We also implement practical heuristics to resolve interference from background traffic and to localize sources of policy violations. We demonstrate the scalability of BUZZ in localizing policy violations on networks with more than 100 nodes.

description: We combine measurements of the longitudinal ($ρ_{xx}$) and Hall ($ρ_{xy}$) resistivities of disordered two dimensional amorphous indium-oxide films to study the magnetic-field tuned superconductor to insulator transition (H-SIT) in the $T \to 0$ limit. At the critical field, $H_c$, the full resistivity tensor is $T$ independent with $ρ_{xx}(H_c) = h/4e^2$ and $ρ_{xy}(H_c)=0$ within experimental uncertainty in all films (i.e. these appear to be "universal" values), this is strongly suggestive that there is a particle-vortex self-duality at $H=H_c$. The transition separates the (presumably) superconducting state at $H H_c$, at which the Hall resistance is $T$ independent and roughly equal to its classical value, $ρ_{xy}\approx H/nec$, marks an additional crossover to a highfield regime (probably to a Fermi-insulator) in which $ρ_{xy} > H/nec$ and possibly diverges as $T\to 0$. We also highlight a profound analogy between the H-SIT and quantum-Hall liquid to insulator transitions (QHIT).

description: We analyse numerically a pinch-type instability in a semi-infinite planar layer of inviscid conducting liquid bounded by solid walls and carrying a uniform electric current. Our model is as simple as possible but still captures the salient features of the instability which otherwise may be obscured by the technical details of more comprehensive numerical models and laboratory experiments. Firstly, we show the instability in liquid metals, which are relatively poor conductors, differs significantly from the astrophysically-relevant Tayler instability. In liquid metals, the instability develops on the magnetic response time scale, which depends on the conductivity and is much longer than the Alfvén time scale, on which the Tayler instability develops in well conducting fluids. Secondly, we show that this instability is an edge effect caused by the curvature of the magnetic field, and its growth rate is determined by the linear current density and independent of the system size. Our results suggest that this instability may affect future liquid metal batteries when their size reaches a few meters.

Destacaremos os principais textos e ideotemas do grande pregador jesuíta onde são cinzeladas visões de Portugal e do futuro da europa e do mundo, de modo a ensaiarmos a compreensão do seu significado no contexto da sua produção retórica e tendo em conta as preocupações nacionalizantes e/ou religiosas que estão na base do discurso em torno do continente em que o seu país se situava e onde estava situada a sede temporal da sua igreja. Portanto, a compreensão da ideia de Portugal em vieira será umbilicalmente interligada com o seu ideário católico fundamental, isto é, com a sua eclesiologia, e coma sua afeção nacionalizante, ou seja, com a sua lusitanologia.

description: The current Internet routing landscape presents a number of challenges, especially in the configuration of routing policies. There have been numerous proposals to tackle the misconfiguration problem: configuration checking, policy language (re)design, and clean-slate routing architecture. In this paper, we present an analysis of routing policies and a misconfiguration detection mechanism. With an operational perspective, we first present a study on the configuration and evolution of routing policies, using data from three different types of networks. Our results show that configurations are changed frequently and mostly incrementally. We found that the most commonly used and changed commands are related to route tagging and filtering, and there are substantial amount of duplication in policy configurations within a network. More interestingly, based on these results, we develop a data mining method to find inconsistencies in a network’s configurations of routing policies. Our method is able to detect local, network-specific rules automatically, and differs from existing approaches that are based on universally applicable rules. In our evaluation, we found 30 confirmed errors and 29 warnings in three networks. More than half of the errors are related to route tagging. Our findings show that the next generation configuration language and routing platform should be sufficiently flexible to allow a network to express and frequently modify its route tagging, yet restrictive enough as this aspect is often misconfigured.
Identidade e alteridade em Teixeira de Pascoaes: Leitura estético-metafísica da figura do Santo como estrangeiro
Creators: name: Carvalho, Sofia

Year: 2014

description: A presente análise estético-metafísica do pensamento de Teixeira Pascoaes, figura incontornável da cultura portuguesa, parte de uma dialéctica de precipitações entre as categorias de identidade e alteridade que não se dissocia de uma cartografia do estrangeiro. A figura do santo recusa a (in)existência pessoal e difunde, no excesso de um processo de saída de si, a admiração do mundo e da alteridade, não como espectador,mas como categoria criativa de todos os existir. O santo propulsiona a tensão plástico-cósmica entre temporal/intemporal e integração/desintegração, numa hierarquia ontocosmogónica que se fundamenta numa metafísica amorosa do procurar(se). Trata-se de uma escatologia do desmascarar ontológico do eu e do absolutamente Outro, o tornar-se estrangeiro nos aspectos plurais de libertação e reclusão.

description: Opresente trabalho visa abordar a fundação do Candomblé, a partir do comércio transatlântico de escravos (do Golfo da Guiné para o brasil), nos séc. XVIII e XIX, e na posterior diáspora, com os casos português e alemão, reconhecendo que tais permissasoperam em função da resposta a estímulos exteriores (processos de alteridade),pelo que a acomodação e a adaptação serão tratadas a partir das noções de ‘adaptação criativa’ (taylOr e lee, s.d.) e ‘hibridismo’ (burKe, 2003; berND, 2004). Ao mesmo tempo, importa observar tal ‘adaptação criativa’ em termos de saudosismoe referenciais imaginários em relação a África e brasil, lugares percebidos como ‘lares imaginados’ (HOWe, 1999). Considera-se que a presente reflexão se constitui da maior importância em função da transnacionalização das religiões africanas e afrodescendentes a meio dos movimentos migratórios. Tal processo não reproduz apenas mecanismos de adaptação mas também novas realidades, i. e., os agentes religiosos são também agentes de transformação social. Transnacionalização, adaptação criativa, hibridismo e mudança social, são conceitos em análise, em referência à Bahia, Lisboa e Berlim.

The unique solution $Θ$ is also shown to be stable in the sense: any solution of the evolutionary Quasi-Geostrophic equation driven by $f$ and starting with finite energy, will return to $Θ$.

description: American teenagers are spending much of their time online. Online communities offer teens perspective, acceptance, connection, and education that were once more limited by geography. However, the online world also opens teens to risks. Adults must decide how to guide teen online behavior in a space that they may not understand. We interviewed 16 experts about teen online behavior, related benefits and risks, and risk mitigation methods. We found that experts agree on certain mitigation methods, especially communication and education about online behavior, but are divided over monitoring. We propose a set of possible solutions that promote online safety while preserving teens’ privacy.

description: We propose STRIDE, a new Internet architecture that provides strong DDoS defense mechanisms for both public services and private end-to-end communication. This new architecture presents several novel concepts including long-term static paths, bandwidth allocation through a top-down topology discovery protocol, dynamic bandwidth allocation via network capabilities, and differentiated packet prioritization. In concert, these mechanisms provide 1) a strong static class bandwidth guarantee, 2) strongly guaranteed capability establishment for private end-to-end communication, and a linear waiting time guarantee in the number of malicious source domains for capability establishment for public services, and 3) globally fair bandwidth allocation for capability-protected flows. STRIDE addresses the denial-of-capability problem and defends against a Coremelt attack by preventing a botnet from crowding out other flows on bottleneck network links. We demonstrate these properties through formal analysis and simulation.

description: We study the dynamics of a mechanical oscillator with linear and cubic forces -the Duffing oscillator- subject to a feedback mechanism that allows the system to sustain autonomous periodic motion with well-defined amplitude and frequency. First, we characterize the autonomous motion for both hardening and softening nonlinearities. Then, we analyze the oscillator's synchronizability by an external periodic force. We find a regime where, unexpectedly, the frequency range where synchronized motion is possible becomes wider as the amplitude of oscillations grows. This effect of nonlinearities may find application in technological uses of mechanical Duffing oscillators -for instance, in the design of time-keeping devices at the microscale- which we briefly review.

description: We propose the continuous-variable quantum key distribution protocol based on the Gaussian modulation of a single quadrature of the coherent states of light, which is aimed to provide simplified implementation compared to the symmetrically modulated Gaussian coherent-state protocols. The protocol waives the necessity in phase quadrature modulation and the corresponding channel transmittance estimation. The security of the protocol against collective attacks in a generally phase-sensitive Gaussian channels is analyzed and is shown achievable upon certain conditions. Robustness of the protocol to channel imperfections is compared to that of the symmetrical coherent-state protocol. The simplified unidimensional protocol is shown possible at a reasonable quantitative cost in terms of key rate and of tolerable channel excess noise.

description: Semi-active suspensions have drawn particular attention due to their superior performance over the other types of suspensions. One of their advantages is that their damping coefficient can be controlled without the need for any external source of power. In this study, three control approaches are implemented on a quarter-car model using MATLAB/Simulink. The investigated control methodologies are Acceleration Driven Damper, Power Driven Damper, and H_infinity Robust Control. The three controllers are known as comfort-oriented approaches. H_infinity Robust Control is an advanced method that guarantees transient performance and rejects external disturbances. It is shown that H_infinity with the proposed modification, has the best performance although its relatively high cost of computation could be potentially considered as a drawback.

description: Background: A primary goal of deuteron electrodisintegration is the possibility of extracting the deuteron momentum distribution. This extraction is inherently fraught with difficulty, as the momentum distribution is not an observable and the extraction relies on theoretical models dependent on other models as input. Purpose: We present a new method for extracting the momentum distribution which takes into account a wide variety of model inputs thus providing a theoretical uncertainty due to the various model constituents. Method: The calculations presented here are using a Bethe-Salpeter like formalism with a wide variety of bound state wave functions, form factors, and final state interactions. We present a method to extract the momentum distributions from experimental cross sections, which takes into account the theoretical uncertainty from the various model constituents entering the calculation. Results: In order to test the extraction pseudo-data was generated, and the extracted "experimental" distribution, which has theoretical uncertainty from the various model inputs, was compared with the theoretical distribution used to generate the pseudo-data. Conclusions: In the examples we compared, the original distribution was typically within the error band of the extracted distribution. The input wave functions do contain some outliers which are discussed in the text, but at least this procedure can provide an upper bound on the deuteron momentum distribution. Due to the reliance on the theoretical calculation to obtain this quantity any extraction method should account for the theoretical error inherent in these calculations due to model inputs.

description: We consider massive half-integer higher spin fields coupled to an external constant electromagnetic field in flat space of an arbitrary dimension and construct a gauge invariant Lagrangian in the linear approximation in the external field. A procedure for finding the gauge-invariant Lagrangians is based on the BRST construction where no off-shell constraints on the fields and on the gauge parameters are imposed from the very beginning. As an example of the general procedure, we derive a gauge invariant Lagrangian for a massive fermionic field with spin 3/2 which contains a set of auxiliary fields and gauge symmetries.

description: Policymakers struggle to determine the proper tradeoffs between data accessibility and data-subject privacy as public records move online. For example, Allegheny County, Pennsylvania recently eliminated the ability to search the county property assessment database using property owners' names. We conducted a user study to determine whether this strategy provides effective privacy protection against a non-expert adversary. We found that removing search by name provides some increased privacy protection, because some users were unable to use other means to determine the address of an individual. However, this privacy protection is limited, and interface usability problems presented a comparable barrier. Our analysis suggests that if policymakers use removal of search by name as a privacy mechanism they should attempt to mitigate usability issues that can hinder legitimate use of public records databases.

description: With the increasing popularity of Near field communication (NFC) in consumer-off-the-shelf devices, more and more applications are taking advantage of the technology in innovative ways. Unfortunately, with the rise of NFC applications, there emerges a variety of vulnerabilities that could leave an unwitting user vulnerable to a data breach. One such potentially devastating attack is mobile pickpocketing, in which an attacker uses a standard NFC-enabled device to read, store, and transmit unprotected personally identifiable information from cards carried by unsuspecting bystanders.
In this paper, we detail the mobile pickpocketing threat, describe inherent vulnerabilities in today’s NFC landscape, and explain how easy it is for a malicious user to exploit them. We define physical and distributed models of the attack. We walk through our experience developing a mobile pickpocketing application, including the capabilities of the application on particular NFC-enabled devices. Finally, we explore short-term and long-term defenses against mobile pickpocketing attacks.
title: Family Business Succession Planning into the Second Generation

description: The sustainability of businesses depends on the ability to create the right succession path that will guide the conduct of executives both present and future. In most firms that are held by shares, the shareholder model makes it possible to elect successors who lead and run affairs to achieve continuity. No such arrangements exist for family businesses and so having a succession plan is of primary importance to such businesses if they want to ensure continuity and sustainability of their operations. Decades of research point to the fact that a good number of family businesses fail to continue to exist after the first-generation owners die. This is due to poor succession planning. The study was conducted with the purpose of facilitating the development of an action plan for a family business to undertake a succession plan. I adopted the case study research strategy. As part of the case study strategy, the company used is SPC, a family business owned by my father, where I was informally managing the business without any formal and clear succession plan. An action research data collection method was used to pursue the purpose of the study. As part of the action research, series of interviews were conducted among with my father, my sister, my brother, and two employees of the family business. There were two phases of the interview. The first phase was the pre-intervention phase. At the pre-intervention phase, the goal behind the interviews was to identify, situate and contextualize the problem that I had perceived due to my personal involvement in the family business. Results from the pre-intervention interviews confirmed the problem and proved that the depth of the problem was worrying and one that needed immediate solution. Most members were also not ready to support a succession plan because they felt there were several intra-family relationship issues that would negatively affect a successful succession plan. The intervention was introduced after the pre-intervention interviews, leading to the second and third interviews at the post-intervention stage. The intervention was in the form of a workshop aimed at equipping members with knowledge about succession planning and brainstorming with them on the need to have a succession plan at SPC. After the post-intervention interview, it was found the knowledge of members about succession planning had increased and they had collectively proposed ways of solving their differences. They were therefore now more willing to design and roll out an action plan of their own. Contributions made from this study are specific to SPC but future researchers can build on it to extend the applicability of its findings to the larger context of family businesses in the country.

description: We consider inverse potential scattering problems where the source of the incident waves is located on a smooth closed surface outside of the inhomogeneity of the media. The scattered waves are measured on the same surface at a fixed value of the energy. We show that this data determines the bounded potential uniquely.

description: The rising demand for high-quality online services requires reliable packet delivery at the network layer. Data-plane fault localization is recognized as a promising means to this end, since it enables a source node to efficiently localize faulty links, find a fault-free path, and enforce contractual obligations among network nodes. Existing fault localization protocols cannot achieve a practical tradeoff between security and efficiency and they require unacceptably long detection delays, and require monitored flows to be impractically long-lived. In this paper, we propose an efficient fault localization protocol called Short-MAC which leverages probabilistic packet authentication and achieves 100 - 10000 times lower detection delay and overhead than related work. We theoretically derive a lower-bound guarantee on data-plane packet delivery in ShortMAC, implement a ShortMAC prototype, and evaluate its effectiveness on two platforms: SSFNet simulator and Linux/Click router. Our implementation and evaluation results show that ShortMAC causes negligible throughput and latency costs while retaining a high level of security.

description: For circuit-based quantum computation, experimental implementation of universal set of quantum logic gates with high-fidelity and strong robustness is essential and central. Quantum gates induced by geometric phases, which depend only on global properties of the evolution paths, have built-in noise-resilience features. Here, we propose and experimentally demonstrate nonadiabatic holonomic single-qubit quantum gates on two dark paths in a trapped $^{171}\mathrm{Yb}^{+}$ ion based on four-level systems with resonant drives. We confirm the implementation with measured gate fidelity through both quantum process tomography and randomized benchmarking methods. Meanwhile, we find that nontrivial holonomic two-qubit quantum gates can also be realized within current experimental technologies. Compared with previous implementations on three-level systems, our experiment share both the advantage of fast nonadiabatic evolution and the merit of robustness against systematic errors, and thus retains the main advantage of geometric phases. Therefore, our experiment confirms a promising method for fast and robust holonomic quantum computation.

description: Gewaltbetroffene Frauen und ihre Kinder erhalten in einem Frauenhaus Sicherheit, Schutz und Begleitung durch Professionelle der Sozialen Arbeit. Rund 40 % der Frauen kehren nicht zum gewaltausübenden Partner zurück. Sie beginnen ein neues Leben. Im Zentrum dieser Arbeit steht dieser Übergang vom Frauenhaus in den Alltag. Aus sozialarbeiterischer Sicht ist es wichtig, diesen Übergang sicher zu gestalten. So ist denn auch die leitende Forschungsfrage, welche Gelingensfaktoren die betroffenen Frauen rekonstruieren. Die vorliegende Arbeit gibt einen Einblick in das Erleben und Gestalten des Übergangs. Die empirische Grundlage bilden drei narrative Interviews mit betroffenen Frauen. Die Datenauswertung folgt mittels Grounded Theory. Unterschiedliche Forschungsfelder zum Phänomen der häuslichen Gewalt wurden bereits bearbeitet. Wissenschaftliche Arbeiten zur unmittelbaren Zeit nach einem Frauen-hausaufenthalt fehlen weitgehend. Durch die Analyse konnten wichtige Faktoren identifiziert werden, welche den Übergang vom Frauenhaus in den Alltag positiv beeinflussen und die soziale Integration der betroffenen Frauen möglich machen. Die Erkenntnis, dass alle Gelingensfaktoren, wie beispielsweise die Sicherheit in einer neuen Wohnung, entscheidend durch gesellschaftliche Strukturen bestimmt und in diesem Sinne politisch verhandelbar sind, ist zentral für die Soziale Arbeit.
