Objective:
CT is the mainstay imaging modality for assessing change in ventricular volume in patients with ventricular shunts or external ventricular drains (EVDs). We evaluated the performance of a novel fully automated CT registration and subtraction method to improve reader accuracy and confidence compared with standard CT.

Methods:
In a retrospective evaluation of 49 ventricular shunt or EVD patients who underwent sequential head CT scans with an automated CT registration tool (CT CoPilot), three readers were assessed on their ability to discern change in ventricular volume between scans using standard axial CT images versus reformats and subtraction images generated by the registration tool. The inter-rater reliability among the readers was calculated using an intraclass correlation coefficient (ICC). Bland–Altman tests were performed to determine reader performance compared to semi-quantitative assessment using the bifrontal horn and third ventricular width. McNemar’s test was used to determine whether the use of the registration tool increased the reader’s level of confidence.

Results:
Inter-rater reliability was higher when using the output of the registration tool (single measure ICC of 0.909 with versus 0.755 without the tool). Agreement between the readers’ assessment of ventricular volume change and the semi-quantitative assessment improved with the registration tool (limits of agreement 4.1 vs 4.3). Furthermore, the tool improved reader confidence in determining increased or decreased ventricular volume (p &lt; 0.001).

Conclusion:
Automated CT registration and subtraction improves the reader's ability to detect change in ventricular volume between sequential scans in patients with ventricular shunts or EVDs.

Advances in knowledge:
Our automated CT registration and subtraction method may serve as a promising generalizable tool for accurate assessment of change in ventricular volume, which can significantly affect clinical management.
Informational Complementarity
Authors: Ke T. Tony , Lin Song 
Published: December 2019

Many products have similar or common attributes and are thus correlated. We show that, when these attributes are uncertain for consumers, a complementarity effect can arise among competing products in the sense that the lower price of one product may increase the demands for the others. This effect occurs when consumers sequentially search for information about both common and idiosyncratic product attributes before purchase. We characterize the optimal search strategy for the correlated search problem, provide the conditions for the existence of the complementarity effect, and show that the effect is robust under a wide range of alternative assumptions. We further explore the implications of the effect for pricing. When firms compete in price, although product correlation may weaken differentiation between the firms, the complementarity effect owing to correlated search may raise equilibrium price and profit.

Tecendo tramas acerca de uma infância sem racismo
Authors: Eurico Marcia Campos 
Published: December 2019

O artigo propõe uma reflexão sobre os impactos do racismo no cotidiano das crianças negras, que têm sua infância marcada pela miséria e pela violência do Estado capitalista. Ao avançar no debate e apresentar a intersecção entre classe social, os papeis de gênero e a questão étnico-racial no processo de reprodução das relações sociais assimétricas no Brasil, é possível identificar como as expressões do patriarcado e do conservadorismo se conectam com o racismo para justificar também a desigualdade social que atinge a infância e reduz as possibilidades de transformação da realidade deste grupo geracional. E, por fim, ocorre a problematização em relação ao lugar marginal do debate sobre relações étnico-raciais e os privilégios da branquitude na área do Serviço Social, bem como sobre o modo como isso destoa do projeto ético-político profissional orientado pela defesa intransigente dos direitos humanos. Palavras-Chave: infância negra; racismo; branquitude; raça/etnia.
Repensando a circulação e a adoção de crianças negras na família brasileira
Authors: Saraiva Vanessa Cristina dos Santos 
Published: December 2019

Este estudo objetiva realizar uma análise das formas de organização, resistência e proteção adotadas historicamente pelas famílias negras brasileiras diante das ações e determinações do Estado. A partir de análise bibliográfica, retomaremos o conceito de circulação historicamente compreendido pelos operadores do direito como uma prática nociva e prejudicial às crianças, a qual era adotada, sobretudo, por famílias negras e empobrecidas do país. Partimos do pressuposto de que esse era um mecanismo adotado por essas famílias para driblar a possibilidade de institucionalização dos filhos em espaços marcados pela violência, destruição de vínculos familiares, afastamento territorial da comunidade e adoções irregulares. Constatamos que se constitui na atualidade como forma de assegurar os direitos dessas crianças quando permite o acesso à família ampliada e à convivência com família paterna. Palavras-Chave: circulação e adoção de crianças; família negra; mulheres negras; resistência; campo sociojurídico.

The recent interest in the upgrade and enhancements of metro transport networks and the availability of transponder cards with coherent receivers is opening the way to filterless solutions employing only passive splitters/couplers and optical amplifiers, potentially achieving significant capital expeditures and operating expenditures savings. However, the filterless option suffers from inefficiencies, mainly due to the broadcasting constraint and the reduced optical reach. To overcome such limitations, this paper proposes three complementary strategies to upgrade optical filterless metro networks (FMN). First, the number of supported channels is incremented by exploiting the full

-band. To this end, two design architectures (i.e., Single and Dual Region) are proposed and evaluated, targeting double capacity with respect to the standard C-band and an upgrade to cost reduction. Second, we investigate a dual-architecture solution, extending metro deployments with a low-cost filterless and unamplified L-band system. Its design trade-offs are evaluated to determine its suitability in providing direct low-latency connectivity between metro-access nodes with the aim of supporting edge-computing platforms. Finally, the flexibility of the FMN is extended by introducing disaggregated transponders with different bitrates (i.e., 100 Gbps and 400 Gbps) and configurable transmission parameters, such as the modulation format and the forward error correction). Such flexibility is exploited through the extension of the OpenConfig YANG model of the optical line system, thus enabling automatic spectrum and transmission parameter assignment by means of a centralized software-defined-network controller and achieving better resource utilization. Simulation and experimental results are provided, showing the effectiveness and the potential impact of filterless metro solutions in future deployments and low-cost network upgrades supporting edge/fog clusters and 5G.
Hybrid art: Towards a new scepticism
Authors: Laskari Iro , Mavrommati Irene , Glinou Eleni 
Published: December 2019

Abstract
In Hybrid artwork, whereby the digital and the real are mixed, the artist/creator has to additionally manage interaction. Interaction is seen as an added dimension to narration: the art piece turns from being a means towards a narration (or an understanding) to a path towards an experience. It is argued that strong metaphysical concepts give place to new more fragmented ones. This nihilism and fragmentation can be seen as a cause of concern but also as an opportunity.
Curatorial perspectives on contemporary art and science dealing with interspecies connections
Authors: Linn Olga Majcen , Ostoić Sunčica 
Published: December 2019

Abstract
This article addresses a curatorial position on specific bioart projects dealing with the topic of interspecies relationships of humans and other mammals, insects and plants through three works by Slovenian authors Saša Spačal, Špela Petricˇ and Maja Smrekar. All the artworks are based on a posthumanist perspective, strongly advocating possibilities of equality in interspecies relations and coexistence, and yet also bear a potential for monstrosity. The subjects, modes and procedures of the artworks analysed are compatible with a curatorial practice able to contribute to and facilitate the development of the concepts of life and species. Representing provocative projects is a challenge not only for the artists but also for the curators who are in the position of having to find adequate production, presentation and promotion support for fringe artistic experiments that infiltrate meaningful topics. Curating that involves taking on the responsibility of endorsing risk-taking artistic practices and posthumanist ideas, dealing with ethical, legal and conceptual challenges is referred to as intense curating.
Symbiotic fictional experiments in the visual arts
Authors: Carvalho Ana 
Published: December 2019

Abstract
Sameness and difference, seen through the use of the term symbiosis, are tooled for the construction of other, future realities. Two examples from literature will describe how symbiosis is, in science fiction, used as means to propose connections with Otherness, through a return to a nature recovered, and as part of rational human deliberate actions towards the recovery of our present damaged planet. Science fiction is where the methodological approach is formulated, as thought experiments, within Ursula Le Guin's literature, from where to develop the process to create two visual artworks. These visual artworks, both different series of images, depart from the term symbiosis, to reflect on what is different within the same, and on the construction of sameness in what is different.
A stride towards sentient cities: Architecture as performance art
Authors: Trickett Terry 
Published: December 2019

Abstract
My researches into 'architecture as music' have led me to investigate how a synchronicity of sound and space, acting together, can enable buildings to become not only smart but also sentient. It was one particular building in the City of London that prompted me to join the patterns of architecture with the rhythms of music in an experimental audio-visual performance called Citirama. Each of the piece's three movements throws some new light on what makes a building 'musical' – i.e. capable of exerting some power over our emotional response. I take a journey back in time to find that architecture is a world of relationships very close to that of the performing musician but, if we are to apply the lessons of music more widely, it will be necessary that we obtain some understanding of how our brains' pathways and neural mechanisms enable us to see and hear through a process of pattern recognition. Only then will the indelible links between architecture and music enable architects to act more as composers in rebalancing the challenges that underpin the future of our cities. I illustrate what I mean by 'musicality' with reference to a specific urban community that is close to home – the Barbican.

The Presentation of the Epicurean Virtues
Authors: Robitzsch Jan Maximilian 
Published: December 2019

AbstractThis paper discusses the presentation of the Epicurean virtues offered in theLetter to Menoeceusand in Cicero’sOn Ends. It evaluates the proposals advanced by Phillip Mitsis and Pierre-Marie Morel. Against Morel, it is argued that Torquatus’ presentation of the virtues inOn Endsis not part of an elaborate dialectical strategy. Instead, the paper sides with Mitsis’ more modest proposal: while Torquatus, like any good speaker, with high likelihood adapts his presentation to his audience, his ideas also have a strong foundation in Epicureanism. Given the extant state of textual evidence, it is difficult to determineprecisely, however, to what degree his presentation of the virtues (1) directly draws on ideas already present in the founder of the Garden himself, (2) reflects a later development in the Epicurean school, or (3) falsifies Epicurean ideas to make them more palatable for a Roman audience.
The practicality of ELF-informed teaching: Attitudes and perceptions of Chinese business English teachers
Authors: Si Jinghui 
Published: December 2019

Abstract
Research on English as a lingua franca (ELF) has proposed a shift from ENL-based (English as a native language) to ELF-informed teaching. This study intends to add empirical evidence on Chinese business English teachers’ perceptions and understanding of the practicality of ELF-informed teaching. Based on interviews with 12 business English teachers, this study presents one main conflict and three subsidiary conflicts regarding the implementation of ELF-informed teaching in the Business English Program. The main conflict is between teachers’ general awareness of ELF and their expressed preference for native-English based teaching. The three subsidiary conflicts are between (i) ENL-based learning and ELF-informed teaching; (ii) English for tests and English for use; (iii) intervention and innovation. Following this, four barriers that impede the implementation of ELF-informed teaching are summarized. This study also discusses course-of-actions that could address the conflicts and barriers in implementing ELF-informed pedagogy in the Chinese context.
Systematicity in linguistic feature selection: Repair sequences and subsequent accommodation
Authors: O’Neal George 
Published: December 2019

AbstractThis study examines linguistic feature selection and its relationship with repair sequences in a longitudinal corpus of Japanese–Filipino business ELF interactions. In the corpus, Japanese employees communicate once a month with Filipino employees via computer software to confirm infrastructure status at a Filipino company’s factories. Comparative constructions frequently appear in the corpus because of the nature of the interactions, but the kinds and frequencies of comparative constructions change month to month. This study demonstrates that early in the corpus, the speakers utilized a multitude of comparative constructions, but after 12 months, the speakers have settled on one preferred comparative construction. Furthermore, the preferred construction emerged from repair sequences, which suggests that repair is significantly related to linguistic feature selection. Accordingly, this study hypothesizes that repair sequences do far more than just resolve an interactional problem; repaired linguistic features are more likely to be selected again the next time a similar linguistic feature is relevant to the progression of the interaction.
An asymptotic property of branching-type overloaded polling networks
Authors: Wang Yuejiao , Liu Zaiming , Chu Yuqing , Li Yingqiu 
Published: December 2019

Abstract
Remerova et al. [Random fluid limit of an overloaded polling model, Adv. Appl. Probab., 2014, 46, 76–101] studied the fluid asymptotics of the joint queue length process for an overloaded cyclic polling system with multigated service discipline by exploiting the connection with multi-type branching processes. In contrast to the heavy traffic behaviors, the cycle time of the overloaded polling system increases by a deterministic times over times under passage to the fluid dynamics and the fluid limit preserves some randomness. The present paper aims to extend the overloaded asymptotics in Remerova et al. [Random fluid limit of an overloaded polling model, Adv. Appl. Probab., 2014, 46, 76–101] to the corresponding polling system with general branching-type service disciplines and customer re-routing policy. A unifying overloaded asymptotic property is derived. Due to the exhaustiveness, the property is a natural extension of the classical polling model with multigated service discipline in Remerova et al. [Random fluid limit of an overloaded polling model, Adv. Appl. Probab., 2014, 46, 76–101] and provides new exact results that have not been observed before for rerouting policy. Additionally, a stochastic simulation is undertaken for the validation of the fluid limit and the optimization of the gating indexes to minimize the total population is considered as an example to demonstrate the usefulness of the random fluid limit.
What Simulations Teach Us About Ordinary Objects
Authors: Schwaninger Arthur C. 
Published: December 2019

AbstractUnder the label ofscientific metaphysics, many naturalist metaphysicians are moving away froma prioriconceptual analysis and instead seek scientific explanations that will help bring forward a unified understanding of the world. This paper first reviews how our classical assumptions about ordinary objects fail to be true in light of quantum mechanics. The paper then explores how our experiences of ordinary objects arise by reflecting on how our neural system operates algorithmically. Contemporary models and simulations in computational neuroscience are shown to provide a theoretical framework that does not conflict with existing fundamental physical theories, and nonetheless helps us make sense of the manifest image. It is argued that we must largely explain how the manifest image arises in algorithmic terms, so that we can pursue a metaphysics about ordinary objects that is scientifically well founded.

A Self-Made Man: Hard Times and the Dickensian Impostor
Authors: Schwanebeck Wieland 
Published: December 2019

Abstract
This essay examines the impostor trope within the works of Charles Dickens, focusing on the example of Josiah Bounderby, the villain of Hard Times (1854), in particular. As a product of the Victorian age’s obsession with character-building and the spirit of industriousness as epitomised in the work of Samuel Smiles, Bounderby not only embodies much of what Dickens found objectionable about utilitarian thought but also a number of tropes that were and remain crucial to the cultural imaginary of the United States (even though Hard Times only briefly alludes to America). As a charismatic rogue who tinkers with his own biography, Bounderby foreshadows the coming of the impostor in turn-of-the-century European literature, an aspect of Hard Times that has so far been overlooked in critical accounts of the novel.
Weimar Wallace: Three Early German Screen Adaptations of Novels by Edgar Wallace (1931–1934)
Authors: Kronshage Eike 
Published: December 2019

AbstractThe article analyzes three little-known films from the early 1930s which are based on novels by British crime thriller writer Edgar Wallace. It presents the films and their genre as a case study for crime cinema and politics in the transition from the Weimar Republic to Nazi Germany by contextualizing them within the rapidly changing film market after January 1933. The series of popular Weimar Wallace films ended abruptly with Hitler’s rise to power, which also put a stop to most of the country’s transnational cinema practices, including film adaptations of novels which were then considered as un-German.
Changes in motor competence over four decades in 10 to 14-year-old Austrian boys
Authors: Greier Klaus , Riechelmann Herbert , Ruedl Gerhard , Drenowatz Clemens 
Published: December 2019

Background: Data on secular trends in motor competence in children and adolescents has been equivocal. While several studies have shown a decline in motor competence over the last several decades there is also research that showed no change or even an increase in motor competence in youth.Methods: Motor competence was assessed via 6 test items in 10- to 14-year-old Austrian boys in the years 1972, 1987 and 2015. At each measurement time participants performed 20m sprint, 800m run, sit ups, jump and reach, one-leg stand and stand and reach tests in the school gymnasium during regular school time. Data across measurement times was compared using weighted means across 5 age groups with pooled standard deviations.Results: Average performance on the 20m sprint, jump and reach test and one leg stand improved significantly (p<0.05) from 1972 to 2015 by 0.3 seconds, 3.9 cm and 3.5 seconds, respectively. Time for the 800m run increased significantly by 15% (p<0.01), indicating a decline in endurance. Flexibility, measured by the stand and reach test, also declined significantly (p=0.02) from 1972 to 2015. There was no significant difference in the number of sit ups performed at the 3 measurement times. Conclusion: Results of the present study do not show a general decline in motor competence in male middle-school students over the last 4 decades. Rather, secular trends differ by specific components contributing to overall motor competence with declines in flexibility and endurance but increases in power, speed and balance.
