description: Research Summary: This article brings together the competitive dynamics and strategy-as-practice literatures to investigate relational competition. Drawing on a global ethnography of the reinsurance market, we develop the concept of micro-competitions, which are the focus of competitors’ everyday competitive practices. We find variation in relational or rivalrous competition by individual competitors across the phases of a micro-competition, between competitors within a micro-competition, and across multiple micro-competitions. These variations arise from the interplay between the unfolding competitive arena and the implementation of each firm's strategic portfolio. We develop a conceptual framework that makes four contributions to: relational competition; reconceptualizing action and response; elaborating on the awareness-motivation-capability framework within competitive dynamics; and the recursive dynamic by which implementing strategy inside firms shapes, and is shaped by, the competitive arena. Managerial Summary: Competition is often seen as war: “attack,” “retaliation,” and “dethronement.” Yet competition can also be relational, incorporating collaboration and reciprocity. We show these dynamics in a syndicated financial market, reinsurance, where multiple competitors get the same price for a share of the same deal. Our competitors have rivalrous motivations to win business and relational motivations to ensure buoyant pricing, maintain market health, and enable long-standing client relationships to persist. These motivations are grounded in the strategizing practices with which firms implement their strategic portfolios and compete on deals. Competitors’ rivalrous or relational motivations are highly dynamic, shifting throughout the competition on any deal and across the multiple deals on which they compete. Cumulatively these practices shape the entire market for these volatile, uncertain financial products.
Violent realities: Stories from an Irish Minority
Creators: name: Walsh, Tony John
Publisher: name: Narrative and Conflict: Explorations in Theory and Practice
Year: 2016

description: The small Irish Protestant minority has had complex, blurred and dramatically changing relationships with roles of both victimizer and victim. It has moved from an alignment with forces of British colonial power to extreme marginality, persecution and the threat of extinction following Irish political Independence. In the last decade it is coping with sudden acceptability and growth. It has moved from being mildly aligned to Britain to being quite fiercly Irish and has been variously (and often simultaneously) execrated, marginalized, silenced, silent, depressed, superior, patronized and patronising.
Utilising Foucaultâ€™s notions of discourse, power and resistance, this paper explores a small number of vignettes emerging from a recent narrative research inquiry into Irish Protestant identity. The paper draws also on Bronwyn Daviesâ€™ concept of positioning through language and social interaction to increase, challenge and complicate our understanding of the layered, nuanced and often contradictory dynamics of victimhood and victimizer in that evolving scenario.

description: Salient object detection (SOD) is a long-standing research topic in computer vision and has drawn an increasing amount of research interest in the past decade. This paper provides the first comprehensive review and benchmark for light field SOD, which has long been lacking in the saliency community. Firstly, we introduce preliminary knowledge on light fields, including theory and data forms, and then review existing studies on light field SOD, covering ten traditional models, seven deep learning-based models, one comparative study, and one brief review. Existing datasets for light field SOD are also summarized with detailed information and statistical analyses. Secondly, we benchmark nine representative light field SOD models together with several cutting-edge RGB-D SOD models on four widely used light field datasets, from which insightful discussions and analyses, including a comparison between light field SOD and RGB-D SOD models, are achieved. Besides, due to the inconsistency of datasets in their current forms, we further generate complete data and supplement focal stacks, depth maps and multi-view images for the inconsistent datasets, making them consistent and unified. Our supplemental data makes a universal benchmark possible. Lastly, because light field SOD is quite a special problem attributed to its diverse data representations and high dependency on acquisition hardware, making it differ greatly from other saliency detection tasks, we provide nine hints into the challenges and future directions, and outline several open issues. We hope our review and benchmarking could help advance research in this field. All the materials including collected models, datasets, benchmarking results, and supplemented light field datasets will be publicly available on our project site https://github.com/kerenfu/LFSOD-Survey.

description: Accessing and understanding contemporary and historical events of global impact such as the US elections and the Olympic Games is a major prerequisite for cross-lingual event analytics that investigate event causes, perception and consequences across country borders. In this paper, we present the Open Event Knowledge Graph (OEKG), a multilingual, event-centric, temporal knowledge graph composed of seven different data sets from multiple application domains, including question answering, entity recommendation and named entity recognition. These data sets are all integrated through an easy-to-use and robust pipeline and by linking to the event-centric knowledge graph EventKG. We describe their common schema and demonstrate the use of the OEKG at the example of three use cases: type-specific image retrieval, hybrid question answering over knowledge graphs and news articles, as well as language-specific event recommendation. The OEKG and its query endpoint are publicly available.

description: Topic detection is the task of determining and tracking hot topics in social media. Twitter is arguably the most popular platform for people to share their ideas with others about different issues. One such prevalent issue is the COVID-19 pandemic. Detecting and tracking topics on these kinds of issues would help governments and healthcare companies deal with this phenomenon. In this paper, we propose a novel, multi-agent, communicative clustering approach, so-called ComStreamClust for clustering sub-topics inside a broader topic, e.g., COVID-19. The proposed approach is parallelizable, and can simultaneously handle several data-point. The LaBSE sentence embedding is used to measure the semantic similarity between two tweets. ComStreamClust has been evaluated on two datasets: the COVID-19 and the FA CUP. The results obtained from ComStreamClust approve the effectiveness of the proposed approach when compared to existing methods.

description: This paper explains how dynamic client portfolios can be a source of ambidexterity (i.e., exploration and exploitation) for knowledge-intensive firms (KIFs). Drawing from a unique qualitative dataset of firms in the global reinsurance market, we show how different types of client relationships underpin a dynamic client portfolio and become a source of ambidexterity for a KIF. We develop a process model to show how KIFs attain knowledge by segmenting their client portfolios, use that knowledge to explore and exploit within and across their client relationships, and dynamically adjust their client portfolios over time. Our study contributes to the literature on external sources of ambidexterity and dynamic management of client knowledge within KIFs.

description: Lightweight and low latency security schemes at the physical layer that have recently attracted a lot of attention include: (i) physical unclonable functions (PUFs), (ii) localization based authentication, and, (iii) secret key generation (SKG) from wireless fading coefficients. In this paper, we focus on short blocklengths and propose a fast, privacy preserving, multi-factor authentication protocol that uniquely combines PUFs, proximity estimation and SKG. We focus on delay constrained applications and demonstrate the performance of the SKG scheme in the short blocklength by providing a numerical comparison of three families of channel codes, including half rate low density parity check codes (LDPC), Bose Chaudhuri Hocquenghem (BCH), and, Polar Slepian Wolf codes for n=512, 1024. The SKG keys are incorporated in a zero-round-trip-time resumption protocol for fast re-authentication. All schemes of the proposed mutual authentication protocol are shown to be secure through formal proofs using Burrows, Abadi and Needham (BAN) and Mao and Boyd (MB) logic as well as the Tamarin-prover.

Between proper and strong edge-colorings of subcubic graphs

description: In a proper edge-coloring the edges of every color form a matching. A matching is induced if the end-vertices of its edges induce a matching. A strong edge-coloring is an edge-coloring in which the edges of every color form an induced matching. We consider intermediate types of edge-colorings, where edges of some colors are allowed to form matchings, and the remaining form induced matchings. Our research is motivated by the conjecture proposed in a recent paper of Gastineau and Togni on S-packing edge-colorings (On S-packing edge-colorings of cubic graphs, Discrete Appl. Math. 259 (2019), 63-75) asserting that by allowing three additional induced matchings, one is able to save one matching color. We prove that every graph with maximum degree 3 can be decomposed into one matching and at most 8 induced matchings, and two matchings and at most 5 induced matchings. We also show that if a graph is in class I, the number of induced matchings can be decreased by one, hence confirming the above-mentioned conjecture for class I graphs.

description: Purpose: Organizational ambidexterity brings together the paradoxical tensions between exploration and exploitation. Embracing such paradoxical tensions depends on both separating the poles to appreciate their distinct elements and integrating them to appreciate their synergies. This paper explores integrative ambidexterity that focuses on the synergies between exploration and exploitation and theorizes these as a single, paradoxical mode of learning. Design/methodology/approach: The authors provide conceptual commentary that aims to expand the attention within the ambidexterity literature from emphasizing separation to further accommodating integration. Findings: The authors outline that attention to separating exploration and exploitation needs to be complemented with a focus on integration, hence, the notion of integrative ambidexterity. Research limitations/implications: The authors surface three processes that advance integrative ambidexterity – novelty via memory; agility via focus; and the potential for improvisation. Together, these dynamics enable organizations to achieve an alternative approach to learning and adaptation. Practical implications: Understanding “integrative ambidexterity,” stressing the synergies between exploration and exploitation, extends the understanding of the nature and approaches to creating learning organizations. The authors three practices offer a potential blueprint to do so. Originality/value: Previous scholarship emphasized how leaders can separate exploration and exploitation by allocating these learning modes to distinct organizational units or addressing them in different time horizons. However, extant authors have less insight about the integration and synergies between exploration and exploitation, and the organizational factors that advance such integration.

description: The star formation history (SFH) of galaxies is critical for understanding galaxy evolution. Hydrodynamical simulations enable us to precisely reconstruct the SFH of galaxies and establish a link to the underlying physical processes. In this work, we present a model to describe individual galaxies' SFHs from three simulations: TheThreeHundred, Illustris-1 and TNG100-1. This model divides the galaxy SFH into two distinct components: the "main sequence" and the "variation". The "main sequence" part is generated by tracing the history of the $SFR-M_*$ main sequence of galaxies across time. The "variation" part consists of the scatter around the main sequence, which is reproduced by fractional Brownian motions. We find that: 1) The evolution of the main sequence varies between simulations; 2) fractional Brownian motions can reproduce many features of SFHs, however, discrepancies still exist; 3) The variations and mass-loss rate are crucial for reconstructing the SFHs of the simulations. This model provides a fair description of the SFHs in simulations. On the other hand, by correlating the fractional Brownian motion model to simulation data, we provide a 'standard' against which to compare simulations.

description: Contrail and cirrus that evolve from contrails represent the largest share of the climate impact from aviation, even larger than the contribution from CO2. In order to reduce this climate impact and the uncertainties related to it, the fundamental science of contrails and their impact on the atmosphere from a present and future aircraft fleet needs to be based on accurate and reliable airborne measurements. Research at DLR has focused on the detection of contrails in a suite of measurement campaigns in the past decade. Different evolution stages of contrails from the first second behind the aircraft until they evolve into contrail cirrus have been measured with national and international partners like NASA and NRC. The lecture covers recent results on contrail properties measured with DLR’s unique research aircraft fleet. The observations are further used to guide model evaluation from the plume to the global scale. While new carbon-free technologies like hydrogen powered engines now come into perspective, their impact on contrail formation is largely unknown. The lectures comments on the importance of airborne measurements of these new type of contrails, the challenges and potentials that come with it to frame a sustainable future air traffic.

description: Future beyond fifth-generation (B5G) and sixth-generation (6G) mobile communications will shift from facilitating interpersonal communications to supporting Internet of Everything (IoE), where intelligent communications with full integration of big data and artificial intelligence (AI) will play an important role in improving network efficiency and providing high-quality service. As a rapid evolving paradigm, the AI-empowered mobile communications demand large amounts of data acquired from real network environment for systematic test and verification. Hence, we build the world's first true-data testbed for 5G/B5G intelligent network (TTIN), which comprises 5G/B5G on-site experimental networks, data acquisition & data warehouse, and AI engine & network optimization. In the TTIN, true network data acquisition, storage, standardization, and analysis are available, which enable system-level online verification of B5G/6G-orientated key technologies and support data-driven network optimization through the closed-loop control mechanism. This paper elaborates on the system architecture and module design of TTIN. Detailed technical specifications and some of the established use cases are also showcased.

description: System operators are faced with increasingly volatile operating conditions. In order to manage system reliability in a cost-effective manner, control room operators are turning to computerised decision support tools based on AI and machine learning. Specifically, Reinforcement Learning (RL) is a promising technique to train agents that suggest grid control actions to operators. In this paper, a simple baseline approach is presented using RL to represent an artificial control room operator that can operate a IEEE 14-bus test case for a duration of 1 week. This agent takes topological switching actions to control power flows on the grid, and is trained on only a single well-chosen scenario. The behaviour of this agent is tested on different time-series of generation and demand, demonstrating its ability to operate the grid successfully in 965 out of 1000 scenarios. The type and variability of topologies suggested by the agent are analysed across the test scenarios, demonstrating efficient and diverse agent behaviour.

description: Conditions affecting the brain are the second leading cause of death globally. One of the main challenges for drugs targeting brain diseases is passing the blood-brain barrier (BBB). Here, the effectiveness of mesoporous silica nanostars (MSiNSs) with two different spike lengths to cross an in vitro BBB multicellular model was evaluated and compared to spherical nanoparticles (MSiNP). A modified sol-gel single-micelle epitaxial growth was used to produce MSiNS, which showed no cytotoxicity or immunogenicity at concentrations of up to 1 μg mL-1 in peripheral blood mononuclear and neuronal cells. The nanostar MSiNS effectively penetrated the BBB model after 24 h, and MSiNS-1 with a shorter spike length (9 ± 2 nm) crossed the in vitro BBB model more rapidly than the MSiNS-2 with longer spikes (18 ± 4 nm) or spherical MSiNP at 96 h, which accumulated in the apical and basolateral sides, respectively. Molecular dynamic simulations illustrated an increase in configurational flexibility of the lipid bilayer during contact with the MSiNS, resulting in wrapping, whereas the MSiNP suppressed membrane fluctuations. This work advances an effective brain drug delivery system based on virus-like shaped MSiNS for the treatment of different brain diseases and a mechanism for their interaction with lipid bilayers.

The measured cross sections exhibit clear signatures of direct double detachment, including double K-hole creation. The shapes of the double-detachment cross sections as a function of photon energy are in accord with Pattard's [J. Phys. B 35, L207 (2002)] empirical scaling law. We have also followed the complex deexcitation cascades that evolve subsequently to the initial double-detachment events by systematic large-scale cascade calculations. The resulting theoretical product charge-state distributions are in good agreement with the experimental findings.

description: Let $V$ be a valuation domain of rank one with quotient field $K$. We study the set of extensions of $V$ to the field of rational functions $K(X)$ induced by pseudo-convergent sequences of $K$ from a topological point of view, endowing this set either with the Zariski or with the constructible topology. In particular, we consider the two subspaces induced by sequences with a prescribed breadth or with a prescribed pseudo-limit. We give some necessary conditions for the Zariski space to be metrizable (under the constructible topology) in terms of the value group and the residue field of $V$.

Introducing our Fall 2016 Volume: A Special Issue on The Politics of Victimhood in Conflict Resolution
Creators: name: Cobb, Sara
name: Winslade, John
Publisher: name: Narrative and Conflict: Explorations in Theory and Practice
Year: 2016

description: We are pleased to present the 4th volume of Narrative & Conflict: Explorations in Theory and Practice, a collection of papers that emerged out of a conference hosted by the Center for Narrative and Conflict Resolution at the School for Conflict Analysis and Resolution,Â  George Mason University. The conference, entitled â€œThe Politics of Victimhood in Conflict Resolutionâ€ was intended to create a dialogic space for inquiry into the complexities of violence and the treatment of victims and perpetrators in research, theory, and practice.

That conference was an opportunity for scholars and practitioners to challenge assumptions about â€œvictimâ€ and â€œvictimizerâ€ roles. As we account for violence, we often formulate victims as passive and perpetrators as agents, a dichotomy that obscures the nuances of political subjectivity and identity in the aftermath of violence, whether genocide, civil war, rape, torture, or interpersonal. As scholars and practitioners puzzle over how to redress suffering in the aftermath of violence, exploration of the dichotomy between victim and perpetrator challenges our emancipatory theories that undergird of feminism, post-colonial studies, oppression and racism. Our inquiry into victims and victimhood becomes ambiguous, calling for a broader discussion of the â€œlanguage gamesâ€ we use to account for violence.

The conference theme and the resulting publication of this Special Issue have relevance for understanding how narratives about victims/perpetrators circulate, as meta-narratives, colonizing and sculpting the public sphere, what can and cannot be said. The papers included in the Special Issue are intended to continue conversations around these complex issues and to highlight the contributions of a narrative lens to our understanding of how the politics of victimhood, and the way in which victims and perpetrators are storied, can open-up or foreclose opportunities for conflict transformation.

We hope you will find this volume of Narrative & Conflicts interesting, challenging and relevant. We invite you to submit your own papers on this topic to the journal and conribute to the extpanson of this conversation.

Cordially,

Sara Cobb & John Winslade, Editors

description: Increasing participation of prosumers in the electricity grid calls for efficient operational strategies for utilizing the flexibility offered by Distributed Energy Resources (DER) to match supply and demand. This paper investigates the coordination performance of a recently proposed coordination scheme for deferrable loads: Forecast Mediated Market Based Control (F-MBC). Enhancements are made to the simulation setup to enable an analysis of performance in realistic scenarios, with heterogeneous loads and an open-ended simulation horizon. Operational scenarios were formulated to showcase the ability of F-MBC to schedule heterogeneous populations of deferrable loads with dynamic load profiles, supported by a mix of renewable and flexible generation. Availability patterns of devices were generated to take into account varying user preferences. Simulation results indicate that F-MBC was able to achieve good distributed scheduling performance for devices with a high initial power consumption. However, performance for devices with low initial power consumption has been found to be less satisfactory. Several directions for further improvement of the F-MBC scheme and its applications are identified.
Victimización de los perpetradores, y criminalización de las victimas

description: La literatura actual acerca de la resolución de conflictos tiende a considerar a los crímenes en comunidades domesticas “libres de conflicto” como un problema de escasa pertinencia para el análisis y la intervención en conflictos. Hay, por ejemplo, poco cuestionamiento acerca de las supuestos normativos acerca de la criminalidad, y, cuando existe, los trabajos operan como si las narrativas de “criminalidad” fueran la variable independiente y el “crimen” fuera una consecuencia unidireccional de la primera. Usando un análisis narrativo, este articulo arguye que el encarcelamiento masivo en los Estados Unidos es el producto de un conflicto latente de larga data, mantenido claramente por la violencia estructura y cultural sostenida por generaciones de narrativas públicas. Nuestro argumento ilustra cómo el encarcelamiento masivo reside mas allá de las conceptualizaciones estándar de conflictos, con frecuencia victimizando a los criminales, criminalizando a las victimas y ofuscando la dicotomía perpetrador/victima. Usamos como objeto de nuestro análisis el proceso de revisión de la libertad condicional iniciado en junio de 2014 por Terry McAuliffe, Gobernador del Estado de Virginia. Con todo, el método y los resultados pueden ser aplicables en escala mayor a todos los Estaos Unidos. “Crimen,” tal cual es considerado en los EEUU, depende de la existencia de una victima, así como de un perpetrador identificable. Concebir al crimen desde una perspectiva narrativa, e integrarlo al campo del análisis de  conflictos tiene consecuencias profundas, ya que ofrece herramientas conceptuales y practicas mas refinadas para identificar y responder a las complejidades del crimen en el contexto norteamericano: nos provee una perspectiva novedosa acerca de raza y clase social en las que la emerge la política de la victimización.

description: Convection is a key transport phenomenon important in many different areas, from hydrodynamics and ocean circulation to planetary atmospheres or stellar physics. However its microscopic understanding still remains challenging. Here we numerically investigate the onset of convective flow in a compressible (non-Oberbeck-Boussinesq) hard disk fluid under a temperature gradient in a gravitational field. We uncover a surprising two-step transition scenario with two different critical temperatures. When the bottom plate temperature reaches a first threshold, convection kicks in (as shown by a structured velocity field) but gravity results in hindered heat transport as compared to the gravity-free case. It is at a second (higher) temperature that a percolation transition of advection zones connecting the hot and cold plates triggers efficient convective heat transport. Interestingly, this novel picture for the convection instability opens the door to unknown piecewise-continuous solutions to the Navier-Stokes equations.

description: Identifying future congestion points in electricity distribution networks is an important challenge distribution system operators face. A proven approach for addressing this challenge is to assess distribution grid adequacy using probabilistic models of future demand. However, computational cost can become a severe challenge when evaluating large probabilistic electricity demand forecasting models with long forecasting horizons. In this paper, Monte Carlo methods are developed to increase the computational efficiency of obtaining asset overload probabilities from a bottom-up stochastic demand model. Cross-entropy optimised importance sampling is contrasted with conventional Monte Carlo sampling. Benchmark results of the proposed methods suggest that the importance sampling-based methods introduced in this work are suitable for estimating rare overload probabilities for assets with a small number of customers.
