Map projections are an area of cartography with a firm mathematical foundation for their creation and display providing a basis for a knowledge representation. Using only variations on a single equation set, an infinite number of projections can be created, but less than 100 are in active use. Because each projection preserves specific characteristics, such as area, angles, global look, or a compromise of properties, classifications of map projections have been developed to aid in knowledge representation. These classifications are used for decision-making. They help select the correct projection for the map use. They assist users with determining the correct orientation, standard parallels and meridians. The classifications also inform the user how to adjust the selection based on size, extent, and latitude. Semantics can be used to automate map projections knowledge into a knowledge base that can be accessed by humans and machines. This work details a semantic representation of map projections knowledge and provides a simple example of a use case that exploits the knowledge base.

<p><strong>Abstract.</strong> A body of knowledge for cartography requires representing knowledge of the specific sub topics in the field. Map projections is a fundamental part of the knowledge base for cartography and a wealth of material exists on knowledge of map projections. Semantic organization of such knowledge is of primary importance to the access and use of map projections knowledge. This project builds a semantic representation for the fundamental parts of map projection knowledge. The semantics capture the concepts and relations between these concepts providing the user an easy method to access the knowledge and apply it to specific problems. The semantics represent classes of projections and the properties associated with those classes as well as the appropriate use. Such a representation can be accessed by humans or machines to arrive at appropriate selection and use of map projection theory.</p>

Although considerable effort has been devoted to building commonsense knowledge bases (CKB), it is still not available for many low-resource languages such as Uyghur because of expensive construction cost. Focusing on this issue, we proposed a cross-lingual knowledge-projection method to construct an Uyghur CKB by projecting ConceptNet’s Chinese facts into Uyghur. We used a Chinese–Uyghur bilingual dictionary to get high-quality entity translation in facts and employed a back-translation method to eliminate the entity-translation ambiguity. Moreover, to tackle the inner relation ambiguity in translated facts, we made a hand-crafted rule to convert the structured facts into natural-language phrases and built the Chinese–Uyghur lingual phrases based on the similarity of phrases that corresponded to the bilingual semantic similarity scoring model. Experimental results show that the accuracy of our semantic similarity scoring model reached 94.75% for our task, and they successfully project 55,872 Chinese facts into Uyghur as well as obtain 67,375 Uyghur facts within a very short period.

Abstract This article focuses on the challenging problem of efficiently detecting changes in mean within multivariate data sequences. Multivariate changepoints can be detected by projecting a multivariate series to a univariate one using a suitable projection direction that preserves a maximal proportion of signal information. However, for some existing approaches the computation of such a projection direction can scale unfavourably with the number of series and might rely on additional assumptions on the data sequences, thus limiting their generality. We introduce BayesProject, a computationally inexpensive Bayesian approach to compute a projection direction in such a setting. The proposed approach allows the incorporation of prior knowledge of the changepoint scenario, when such information is available, which can help to increase the accuracy of the method. A simulation study shows that BayesProject is robust, yields projections close to the oracle projection direction and, moreover, that its accuracy in detecting changepoints is comparable to, or better than, existing algorithms while scaling linearly with the number of series.

The main intention of this text is to present three inter-connected projections of the current global crisis of the postmodern capitalism: discursive, sociological and cultural/political. Discursive projection is considering the crisis of the postmodern capitalism through the perspective of the discursive paradigmatic restructuring (social link), sociological projection is giving interpretation of the postmodern social economy paradigm (society of knowledge), whilst the cultural/political projection is discussing the postmodern ideological forms of everyday life (cultural capitalism). In the last instance, all three are raising a question: Is there any good alternative?

Taiwan’s climate change projections have always presented a challenge due to Taiwan’s size and unique meteorological and geographical characteristics. The Taiwan Climate Change Projection Information and Adaptation Knowledge Platform (TCCIP), funded by the Ministry of Science and Technology, Taiwan, is a decade-long climate research project with the most predominant climate data provider and national adaptation policymaking in the country. This paper outlines the evolution of the project. It describes the project’s major achievements, including climate projection arising from participation in the WCRP Coupled Model Inter-comparison Project (CMIP), dynamically and statistically downscaled data with resolutions up to 5 km grid, impact assessments of various themes, such as flooding, as well as the support of national policies through approaches including risk maps, climate data, and knowledge brokering.

ABSTRACT “Dusting Off that Old Projector: Preservation through Projection” makes the case that institutions that hold film prints and projectors—especially rarities, one-offs, and nonstandard gauges—should consider projecting films in an effort to preserve and perpetuate knowledge about the history of film technology. The authors use the success of Home Movie Day as a model for considering preservation through projection and to question absolutist protective strategies. Their aim is to expand the way that archivists, scholars, and the general public think about the significance of unusual film formats and equipment in relation to film history.

Map projections are one of the foundations of geographic information science and cartography. An understanding of the different projection variants and properties is critical when creating maps or carrying out geospatial analyses. The common way of teaching map projections in text books makes use of the light source (or light bulb) metaphor, which draws a comparison between the construction of a map projection and the way light rays travel from the light source to the projection surface. Although conceptually plausible, such explanations were created for the static instructions in textbooks. Modern web technologies may provide a more comprehensive learning experience by allowing the student to interactively explore (in guided or unguided mode) the way map projections can be constructed following the light source metaphor. The implementation of this approach, however, is not trivial as it requires detailed knowledge of map projections and computer graphics. Therefore, this paper describes the underlying computational methods and presents a prototype as an example of how this concept can be applied in practice. The prototype will be integrated into the Geographic Information Technology Training Alliance (GITTA) platform to complement the lesson on map projections.

nfluenced by factors like mud, frame, rivet, space mark and plate slant, plate character segmentation tends to be inaccurate and even results in mistakes. In order to tackle these problems, this paper puts forward a plate character segmentation algorithm based on projection feature and prior knowledge. That is, firstly of all, to carry out horizontal coarse segmentation by horizontal projection, then use both vertical projection and prior knowledge to conduct vertical segmentation. At last, to carry out horizontal fine segmentation by local projection. The experiment demonstrates that such algorithm can solve the above mentioned problems accurately and practically with high-efficiency.

The shoulder is a complex anatomical structure and imaging plays an important role in the diagnosis and management of shoulder conditions. The complexity of the shoulder’s anatomy has led to the development of multiple radiographic projections and techniques within plain film imaging with each projection intended to demonstrate specific aspects of the anatomy of the shoulder. However, reproducing the required projections can be difficult especially if radiographers are not familiar with the projections and their evaluation criteria. Literature has revealed the importance of a comprehensive knowledge and understanding of anatomy, patient positioning, beam direction and centring point, and evaluation criteria to ensure a quality projection for accurate diagnoses. The aim of the study was to determine the knowledge and understanding of radiographers with regard to the supraspinatus outlet projection (SOP) for shoulder impingement syndrome (SIS) and its evaluation criteria. The inferences derived from the research findings were used to develop guidelines for a structured in-service training programme for practising radiographers to optimise their knowledge and understanding of the supraspinatus outlet projection in shoulder impingement syndrome. The proposed study followed a quantitative approach. Furthermore, a descriptive, exploratory, contextual design was employed. The research population consisted of practising radiographers working in the public and private hospitals of the Nelson Mandela Bay Municipality. The data were collected by means of a structured self-administered questionnaire. The questionnaire comprised of three sections. The first section requested demographic information from the participants. The second section assessed their knowledge and understanding regarding the scapular ‘Y’ and the supraspinatus outlet projections and shoulder impingement syndrome. The third section assessed their knowledge and understanding of anatomy and image evaluation/critiquing. The reliability and validity of the data collection instrument was ensured by conducting a pilot study and comparing the results with those of the main study. In addition, the expertise and guidance of a radiographer experienced in the clinical training of radiographers, the supervisor (who has twenty years’ experience in the teaching of radiographers) and a statistician was obtained. Descriptive and inferential statistical analyses were performed by means of a statistical programme and with the guidance of a statistician. The researcher ensured that the study was conducted in an ethical manner by adhering to the ethical principles of beneficence, justice and respect for persons.

Explaining the mechanism behind a genetic disease involves two phases, collecting and analyzing data associated to the disease, then interpreting those data in the context of biological systems. The objective of this dissertation was to develop a method of integrating complementary datasets surrounding any single biological process, with the goal of presenting the response to a signal in terms of a set of downstream biological effects. This dissertation specifically tests the hypothesis that computational projection methods overlaid with domain expertise can direct research towards relevant systems-level signals underlying complex genetic disease. To this end, I developed a software algorithm named Geneset Enrichment and Projection Displays (GSEPD) that can visualize multidimensional genetic expression to identify the biologically relevant gene sets that are altered in response to a biological process.

This dissertation highlights a problem of data interpretation facing the medical research community, and shows how computational sciences can help. By bringing annotation and expression datasets together, a new analytical and software method was produced that helps unravel complicated experimental and biological data.

The dissertation shows four coauthored studies where the experts in their field have desired to annotate functional significance to a gene-centric experiment. Using GSEPD to show inherently high dimensional data as a simple colored graph, a subspace vector projection directly calculated how each sample behaves like test conditions. The end-user medical researcher understands their data as a series of somewhat-independent subsystems, and GSEPD provides a dimensionality reduction for high throughput experiments of limited sample size. Gene Ontology analyses are accessible on a sample-to-sample level, and this work highlights not just the expected biological systems, but many annotated results available in vast online databases.

Un des enjeux actuels de la recherche en cryptographie est la mise au point de primitives cryptographiques avancées assurant un haut niveau de confiance. Dans cette thèse, nous nous intéressons à leur conception, en prouvant leur sécurité relativement à des hypothèses algorithmiques bien étudiées. Mes travaux s'appuient sur la linéarité du chiffrement homomorphe, qui permet d'effectuer des opérations linéaires sur des données chiffrées. Précisément, je suis partie d'un tel chiffrement, introduit par Castagnos et Laguillaumie à CT-RSA'15, ayant la particularité d'avoir un espace des messages clairs d'ordre premier. Afin d'aborder une approche modulaire, j'ai conçu à partir de ce chiffrement des outils techniques (fonctions de hachage projectives, preuves à divulgation nulle de connaissances) qui offrent un cadre riche se prêtant à de nombreuses applications. Ce cadre m'a d'abord permis de construire des schémas de chiffrement fonctionnel; cette primitive très expressive permet un accès mesuré à l'information contenue dans une base de données chiffrée. Puis, dans un autre registre, mais à partir de ces mêmes outils, j'ai conçu des signatures numériques à seuil, permettant de partager une clé secrète entre plusieurs utilisateurs, de sorte que ceux-ci doivent collaborer afin de produire des signatures valides. Ce type de signatures permet entre autres de sécuriser les portefeuilles de crypto-monnaie. De nets gains d'efficacité, notamment en termes de bande passante, apparaissent en instanciant ces constructions à l'aide de groupes de classes. Mes travaux se positionnent d'ailleurs en première ligne du renouveau que connait, depuis quelques années, l’utilisation de ces objets en cryptographie
One of the current challenges in cryptographic research is the development of advanced cryptographic primitives ensuring a high level of confidence. In this thesis, we focus on their design, while proving their security under well-studied algorithmic assumptions.My work grounds itself on the linearity of homomorphic encryption, which allows to perform linear operations on encrypted data. Precisely, I built upon the linearly homomorphic encryption scheme introduced by Castagnos and Laguillaumie at CT-RSA'15. Their scheme possesses the unusual property of having a prime order plaintext space, whose size can essentially be tailored to ones' needs. Aiming at a modular approach, I designed from their work technical tools (projective hash functions, zero-knowledge proofs of knowledge) which provide a rich framework lending itself to many applications.This framework first allowed me to build functional encryption schemes; this highly expressive primitive allows a fine grained access to the information contained in e.g., an encrypted database. Then, in a different vein, but from these same tools, I designed threshold digital signatures, allowing a secret key to be shared among multiple users, so that the latter must collaborate in order to produce valid signatures. Such signatures can be used, among other applications, to secure crypto-currency wallets. Significant efficiency gains, namely in terms of bandwidth, result from the instantiation of these constructions from class groups. This work is at the forefront of the revival these mathematical objects have seen in cryptography over the last few years

Dans ce travail, nous proposons un système de recalage géométrique possibiliste qui fusionne les connaissances sémantiques et les connaissances au niveau du gris des images à recaler. Les méthodes de recalage géométrique existantes se reposent sur une analyse des connaissances au niveau des capteurs lors de la détection des primitives ainsi que lors de la mise en correspondance. L'évaluation des résultats de ces méthodes de recalage géométrique présente des limites au niveau de la perfection de la précision causées par le nombre important de faux amers. L’idée principale de notre approche proposée est de transformer les deux images à recaler en un ensemble de projections issues des images originales (source et cible). Cet ensemble est composé des images nommées « cartes de possibilité », dont chaque carte comporte un seul contenu et présente une distribution possibiliste d’une classe sémantique des deux images originales. Le système de recalage géométrique basé sur la théorie de possibilités proposé présente deux contextes : un contexte supervisé et un contexte non supervisé. Pour le premier cas de figure nous proposons une méthode de classification supervisée basée sur la théorie des possibilités utilisant les modèles d'apprentissage. Pour le contexte non supervisé, nous proposons une méthode de clustering possibiliste utilisant la méthode FCM-multicentroide. Les deux méthodes proposées fournissent en résultat les ensembles de classes sémantiques des deux images à recaler. Nous créons par la suite, les bases de connaissances pour le système de recalage possibiliste proposé. Nous avons amélioré la qualité du recalage géométrique existant en termes de perfection de précision, de diminution du nombre de faux amers et d'optimisation de la complexité temporelle
In this work, we propose a possibilistic geometric registration system that merges the semantic knowledge and the gray level knowledge of the images to be registered. The existing geometric registration methods are based on an analysis of the knowledge at the level of the sensors during the detection of the primitives as well as during the matching. The evaluation of the results of these geometric registration methods has limits in terms of the perfection of the precision caused by the large number of outliers. The main idea of our proposed approach is to transform the two images to be registered into a set of projections from the original images (source and target). This set is composed of images called “possibility maps”, each map of which has a single content and presents a possibilistic distribution of a semantic class of the two original images. The proposed geometric registration system based on the possibility theory presents two contexts: a supervised context and an unsupervised context. For the first case, we propose a supervised classification method based on the theory of possibilities using learning models. For the unsupervised context, we propose a possibilistic clustering method using the FCM-multicentroid method. The two proposed methods provide as a result the sets of semantic classes of the two images to be registered. We then create the knowledge bases for the proposed possibilistic registration system. We have improved the quality of the existing geometric registration in terms of precision perfection, reductionin the number of false landmarks and optimization of time complexity

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1989.
Includes bibliographical references (p. 105-109).
This thesis is an effort to begin to understand some of the problems and possibilities of architectural production in an age of advanced information technologies. The driving concern behind this work is the increasing distance between our environmental understandings, as they are affected by these new technologies, and the immediate physicality of the world around us. This increasing distance has been further exaggerated by our shift into more and more complex systems of architectural production, making us less and less likely to stay in touch with the full informational content of the physical materials and processes involved in that production. This thesis strives toward an attitude toward design which respects the information and knowledge content of the components and processes of architecture as a complex artifact Part of the attempt here is to consider the opportunities for relaxing the tendency to impose our will insensitively on the true nature of things. It seems that as we alieviate this tendency, we might begin to construct environments which sustain us in more meaningful ways. The thesis itself is composed of six parts: -- Section One discusses developments in the cultural role of museums in recent years and the importance of museums as a way of transferring knowledge. Also introduced in this part is the notion of a host museum; responding to a perceived need for local forums LO foster greater awareness of our physical and cultural environments. -- Section Two introduces the site in Cambridge as an urban setting, including some of its history and its physical and social significance. -- Section Three presents general architectural concerns addressed in the project, illustrated through references and diagrams of design decisions, grouped into five categories of issues, from urban context lO material deployment. -- Section Four elaborates on the setting of these design decisions within the larger context of 'forming', regarding the process of design as a decision structure for the management of physical information. -- Section Five presents the specific design decisions realized in the project (in accord with the five categories established in Section Three) illustrated through plans, sections, detail studies, etc. -- Section Six proposes an understanding of architectural artifacts as manifestations of their decision structure and offers the beginnings of a theory of production based on the exploitation of "cheap information."

Les smooth (ou universal) projective hash functions ont été introduites par Cramer et Shoup, à Eurocrypt'02, comme un outil pour construire des schémas de chiffrement efficaces et sûrs contre les attaques à chiffrés choisis. Depuis, elles ont trouvé de nombreuses applications, notamment pour la construction de schémas d'authentification par mot de passe, d'oblivious transfer, de signatures en blanc, et de preuves à divulgation nulle de connaissance. Elles peuvent êtres vues comme des preuves implicites d'appartenance à certains langages. Un problème important est de caractériser pour quels langages de telles fonctions existent.Dans cette thèse, nous avançons dans la résolution de ce problème en proposant la notion de diverse modules. Un diverse module est une représentation d'un langage, comme un sous-module d'un module plus grand, un module étant un espace vectoriel sur un anneau. À n'importe quel diverse module est associée une smooth projective hash function pour le même langage. Par ailleurs, presque toutes les smooth projective hash functions actuelles sont construites de cette manière.Mais les diverse modules sont aussi intéressants en eux-mêmes. Grâce à leur structure algébrique, nous montrons qu'ils peuvent facilement être combinés pour permettre de nouvelles applications, comme les preuves implicites à divulgation nulle de connaissance (une alternative légère aux preuves non-interactives à divulgation nulle de connaissance), ainsi que des preuves non-interactives à divulgation nulle de connaissance et one-time simulation-sound très efficaces pour les langages linéaires sur les groupes cycliques
Smooth (or universal) projective hash functions were first introduced by Cramer and Shoup, at Eurocrypt'02, as a tool to construct efficient encryption schemes, indistinguishable under chosen-ciphertext attacks. Since then, they have found many other applications, including password-authenticated key exchange, oblivious transfer, blind signatures, and zero-knowledge arguments. They can be seen as implicit proofs of membership for certain languages. An important question is to characterize which languages they can handle.In this thesis, we make a step forward towards this goal, by introducing diverse modules. A diverse module is a representation of a language, as a submodule of a larger module, where a module is essentially a vector space over a ring. Any diverse module directly yields a smooth projective hash function for the corresponding language, and almost all the known smooth projective hash functions are constructed this way.Diverse modules are also valuable in their own right. Thanks to their algebraic structural properties, we show that they can be easily combined to provide new applications related to zero-knowledge notions, such as implicit zero-knowledge arguments (a lightweight alternative to non-interactive zero-knowledge arguments), and very efficient one-time simulation-sound (quasi-adaptive) non-interactive zero-knowledge arguments for linear languages over cyclic groups

Mestrado em Gestão de Projetos
Para o Project Management Institute (PMI) "governação é definida como o processo de desenvolvimento, comunicação, execução e acompanhamento assegurando as políticas, procedimentos, estruturas organizacionais e práticas associadas a um determinado programa?. No contexto organizacional, proporciona um quadro para a tomada de decisões e ações de gestão éticas, baseadas na transparência, responsabilidades e papeis bem definidos (Too & Weaver, 2014b). No âmbito específico da gestão de projetos é um garante que o portfólio de projetos está alinhado com os objetivos da organização, e é entregue de forma eficiente e sustentável suportando os meios pelos quais a gestão e outras importantes partes interessadas, recebem a informação oportuna, relevante e fiável (APM, 2004). No presente trabalho é usada para classificar os modelos postos em prática pelo Project Management Office, no apoio a projetos ou programas através dos processos de partilha de conhecimento (Garland, 2009). Na medida em que estudos anteriores referem consistentemente lacunas na investigação nesta área, o objetivo da presente dissertação será assim de examinar o papel estratégico da governança do Project management office e qual a sua verdadeira influência nos processos de partilha do conhecimento entre projetos. Serão ainda observadas as barreiras e motivações para a real e positiva transferência de conhecimento, numa perspetiva em como os gestores de projeto percecionam as políticas implementadas.
For the Project Management Institute (PMI), "governance is defined as the process of development, communication, implementation and monitoring, ensuring the policies, procedures, organizational structures and practices associated with a particular program." In the organizational context, provides a framework for decision making and ethical management actions based on transparency, responsibility and well-defined roles (Too & Weaver, 2014b). In the specific scope of project management it is a guarantee that the project portfolio is aligned with the organization's goals, and is delivered in an efficient and sustainable manner, supporting the means by which management and other key stakeholders receive timely, relevant and reliable information (APM, 2004). In this study it is used to classify the implemented models of the Project Management Office, to support projects or programs in knowledge sharing processes (Garland, 2009). As previous studies consistently refer research gaps in this area, the purpose of this dissertation will be to examine the governance strategic role of the Project Management Office and what is its real influence on knowledge sharing processes between projects. Both obstacles and motivations will also be observed for the real knowledge transfer, in the perception how project managers understand the implemented policies.

This thesis is about the mobilities of geographical knowledge in the material form of lantern-slides and the forces exerted on these by technological and human factors. Owing to its concern with matter, human- and non-human, and its circulation, the thesis addresses the physics of geographical knowledge. The chapters below investigate the Royal Geographical Society’s (RGS) ongoing tradition of telling stories of science and exploration through words, objects and pictures in the final quarter of the nineteenth century and as geography professionalized and geographical science developed. These processes occurred within the context of a plethora of technological innovations, including the combination of the older medium of the magic lantern and photographic lantern-slides, integral to a wide range of entertainment, scientific and educational performances across Britain. In 1886 the RGS began to engage with the magic lantern. Via this technology and the interactive lecture performances in which it featured, I argue that the Society embraced the medium of photography, thereby engendering transformations in methods of knowledge making and to the RGS collections. I study how these transformations influenced the discipline of Geography as it was re-established at the University of Oxford in 1887. I demonstrate the evolution of the RGS’s Evening, Technical and Young Persons’ lectures, their contingent lantern-slide practices and, consequently, how these moulded, and were moulded by, the RGS Fellowship between c. 1885 and 1924. The chapters below explore how these innovations in visual technologies and practices arose, how they circulated knowledge and their effect on geographies of geographical knowledge making. By harnessing the lantern the RGS attracted an expanding and diversifying audience demographic. The thesis demonstrates the interactive nature of RGS lantern-slide lectures and audiences' important role in shaping the Society’s practices and geographical knowledge. The chapters below argue that it was via the use of the lantern that geography was disseminated to new places. The thesis therefore brings additional perspectives and dimensions to understandings of the circulation of geographical knowledge.

L'angiographie par rayons X est la modalité d'imagerie médicale la plus utilisée pour l'exploration des pathologies des vaisseaux coronariens. La routine clinique actuelle repose sur l'utilisation brute des images angiographiques. Pourtant, ces images présentent des défauts tels que le raccourcissement des longueurs, l'effet de grandissement ou la présence de superpositions. Ces faiblesses peuvent fausser le diagnostic et le choix thérapeutique. Nous proposons d'exploiter un nouveau mode d'acquisition angiographique, le mode rotationnel, pour produire des modélisations tridimensionnelles et dynamiques de l'arbre coronaire. Ces modélisations permettraient de s'affranchir des défauts intrinsèques aux images. Notre travail se compose de trois étapes. Dans un premier temps, une reconstruction 3D multi-oculaire donne un modèle statique des lignes centrales des artères coronaires, prenant en compte le mouvement respiratoire. Par la suite, un mouvement 4D des artères coronaires est determiné sur l'ensemble du cycle cardiaque. Enfin, la connaissance des mouvements respiratoire et cardiaque permet de réaliser la reconstruction tomographique des artères coronaires. Nous avons testé notre approche sur une base de 22 patients et avons proposé de nouveaux outils et applications cliniques à partir de ces modélisations tridimensionnelles et dynamiques. Ces outils diagnostiques ont été prototypés et feront l'objet d'une validation clinique.

The collapse of Charles I’s Personal Rule did not end projecting activities. This chapter uses the well-documented case of the reforming circle of Samuel Hartlib during the 1640s and 1650s to explore how public distrust of the projector came to condition the promotion of useful knowledge, especially the evaluation of credibility and the practices of collaboration and exclusion in the reforming network. Many promoters came to avoid the style of fiscal impositions reminiscent of early Stuart projectors. The chapter discusses how projecting activities thereby began to evolve away from the early Stuart model, with far-reaching implications for subsequent developments, not only in terms of political economy, but also of natural and experimental philosophy.

Classical Projections theorizes a new term, “film quotation,” for the medium-specific repurposing, re-framing, and re-viewing of preexisting films within subsequent films. As a visual corollary to literary quotation, film quotation embeds film fragments within on-screen televisions, movie theaters, and computer screens. Quotation accesses the way the humanities make meaning; the pull-quote, epigraph, and quotation are standard for citing evidence, invoking authority, or interrogating literary and scholarly writing. Film studies has yet to seriously examine how film quotations convene interaction and create new knowledge across time. Classical Projections focuses on film quotations of classical Hollywood film—mainstream American studio production, 1915–1950—as quoted in post-classical Hollywood, roughly 1960 to present. Though film quotation has been used since early silent cinema, this strategic historical frame asks, How does post-classical cinema visualize its own “belatedness,” its awareness of coming after a “classical” or “golden age”? How do post-classical filmmakers claim or disavow classical history? How do historically disenfranchised post-classical filmmakers, whether marginalized by gender, sexuality, or race, grapple with exclusionary and stereotype-ridden canons? As a constitutive element of post-classical authorship, film quotations amass and manufacture “classical” Hollywood in retrospective, highly strategic ways. Considering both archival quotations and “created-quotations,” which are fabricated by the quoting filmmakers, uncovers the images, voices, and fragments of the “classical” canon that either never existed, were never preserved, were mired in caricature, or that classical Hollywood could not “image/imagine.” By revealing how quotational tellings of film history build and embolden exclusionary, myopic canons, Classical Projections uncovers opportunities to construct more capacious cultural memory.

In anesthesia, situation awareness (SA) represents the degree to which an anesthetist perceives the information in her or his environment, comprehends the patient’s situation, and projects the patient’s situation into the future. There are three levels of SA: perception, comprehension, and projection. After perception, basic information has to be integrated, and several cognitive mechanisms enable correct, complete, and quick development of SA. These processes require long-term memory content such as mental models, similar (prototypical) situations that have been experienced earlier, automaticity, and medical knowledge including guidelines and algorithms. Several tools have the potential to provide qualitative and quantitative assessment of SA in anesthesia, including goal-directed task analysis (GDTA) and SA error taxonomy. In this chapter, the role of SA in anesthesia is illustrated, and factors are described that have the potential for either enhancing or hindering the development of adequate SA.

Abstract Most statistical agencies consult with experts in some manner prior to formulating their assumptions about the future. Expert judgment is valuable when there is either a lack of good data, insufficient knowledge about underlying causal mechanisms, or apparent randomness in trends. In this paper, we describe the expert elicitation protocol developed by Statistics Canada in 2018 to inform the development of projection assumptions. The protocol may be useful for projection makers looking to adopt a formal approach to eliciting expert judgments, or for producing probabilistic projections, where it is necessary to obtain plausible estimates of uncertainty for components of population growth.

The supposed benefits of hypersonic missile technology and the reconsideration of the European security landscape following Russia’s 2022 invasion of Ukraine may act as a catalyst for multiple European states to acquire or develop high-speed systems. Although these systems are currently challenging to develop, trends in other missile technology point towards a gradual diffusion of explicit and tacit knowledge that ultimately lowers production costs, resulting in greater affordability and accessibility. Coupled with inefficient non-proliferation barriers and the gradual erosion of the cold war arms control architecture, it is likely that these systems will be fielded by several European countries in the next 10 to 15 years. Reflecting this projection, this paper considers in detail various European hypersonic missile programmes and explains the applications of these systems and their possible implications for European stability, including existing technical and policy barriers that impede proliferation. In unravelling these, the paper proposes how policymakers can strengthen these mechanisms, achieve deterrence without undermining stability and better manage this emerging security issue.

Data management systems impose structure on data via a static representation schema or data structure. Information from the data is extracted by executing queries based on predefined operators. This paradigm restricts the searchability of the data to concepts and relationships that are known or assumed to exist among the objects. While this is an effective and efficient means of retrieving simple information, we propose that such a structure severely limits the ability to derive breakthrough knowledge that exists in data under the guise of “unknown unknowns.” A dynamic system will alleviate this dependence, allowing theoretically infinite projections of the data to reveal discoverable relationships that are hidden by traditional use case-driven, static query systems. In this paper, we propose a framework for a data-responsive query algebra based on a dynamic hyperbolic surface model. Such a model could provide more intuitive access to analytics and insights from massive, aggregated datasets than existing methods. This model will significantly alter the means of addressing the underlying data by representing it as an arrangement on a dynamic, hyperbolic plane. Consequently, querying the data can be viewed as a process similar to quantum annealing, in terms of characterizing data representation as an energy minimization problem with numerous minima.
