Résumé :
In a recent article inPS, Soroka and Wlezien (2008) argue that the policy preferences of low- and high-income Americans rarely differ, and therefore that “regardless of whose preferences policymakers follow … policy will end up in essentially the same place” (325). In this article, I analyze a much larger and more diverse set of policies than those examined by Soroka and Wlezien and show that income-based preference gaps are much larger and more widespread than their data suggest. In terms of federal government policy, the affluent are far better represented than the poor; the findings in this paper indicate that this representational inequality has substantial repercussions across a wide range of policy issues.

Résumé :
OBJECTIVES: to describe and analyze the centrality, the mute zone and the attitudes expressed in nurses' social representations of people with Human Immunodeficiency Virus. METHOD: the subjects were 30 nurses from a university hospital in Rio de Janeiro. The data was collected using a Likert scale. RESULTS: the data pointed to a process of representational change regarding Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome, with the assumption of a more positive attitude regarding living with this health issue. The hypothesis of the existence of a mute zone in the representation, comprising elements with a contranormative character, was strengthened. CONCLUSION: the influence of the dynamics of social normativity on how the social representations studied are expressed may contribute to a better understanding of its structuring process. It also helps in the analysis of possible gaps among the nurses' discourses and practices in relation to Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome.

Résumé :
Often, the senders and receivers of scientific communication have different knowledge bases. While such communication is essential for solving the complex social and technological problems that affect multiple stakeholders, a diversity of knowledge among communicators can create representational gaps (rGaps). rGaps occur when senders make assumptions that receivers do not, creating conflict over the meaning and value of the information communicated. Such conflict could, if managed, promote learning and innovation as communicators reconcile their assumptions. More often, however, rGaps cause conflict to transform from a debate that informs to an argument that divides. Managing rGap conflict so that it does not degrade communication requires relationship building to mitigate the negative by-products of persistent conflict while maintaining appropriate levels of cognitive distinctiveness among diverse stakeholders. Thus, we provide a framework for identifying and leveraging rGaps through managed conflict so that communication between those with different perspectives builds rather than burns bridges.

Résumé :
Abstract As the efforts of the Global Age-friendly Cities and Communities movement mature and continue to grapple with society’s shifting dynamics, blind spots and knowledge gaps are exposed. This research applies critical discourse analysis to examine the evolution of Age-friendly NYC using an intersectional lens committed to an ethics of representation. Over 1,000 pages of public records were analyzed to trace the history of this movement in relation to age, race, sexuality, gender, ability, and class. Findings suggest that Age-friendly NYC is a global leader of the age-friendly movement, yet social identities are represented neither equally nor universally in its initiatives. Discussions of race, sexuality, and gender are subtle. They also overlook how these identities may intersect and shape the aging experience for differently positioned older adults. A comprehensive understanding of the aging experiences of those with multiple intersecting identities is needed to inform future age-friendly policies and programs.

Texte intégral
Résumé :
Radar-rainfall uncertainty quantification has been recognized as an intricate problem due to the complexity of the multi-dimensional error structure, which is also associated with space and time scale. The error structure is usually characterized by two moments of the error distribution: bias and error variance. Despite numerous efforts to investigate radar-rainfall uncertainties, many questions remain unanswered. This dissertation uses two statistical descriptions (mean and variance) of the error distribution to highlight and describe some of the remaining gaps in representing radar-rainfall uncertainties. The four central issues addressed in this dissertation include: 1. Investigation of radar relative bias caused by radar calibration. 2. Statistical modeling of range-dependent error arising from the radar beam geometry structure. 3. Scale-dependent variability of radar-rainfall and rain gauge error covariance. 4. Scale-dependence of radar-rainfall error variance. The first two issues describe systematic features of main error sources of radar-rainfall. The other two are associated with quantifying radar error variance using the error variance separation (EVS) method, which considers the spatial sampling mismatch between radar and rain gauge data. This study captures the main systematic features (systematic bias arising from radar calibration and range-dependent errors) of radar measurements without using ground reference data and the error variance structure with respect to the spatio-temporal transformation of the measurements for further applications to hydrologic fields. Such consideration of radar-rainfall uncertainties represented by error mean and variance can enhance the characterization of the uncertainty structure and yield a better understanding of the physical process of precipitation.

Résumé :
In the era of digital transformation, an increasing number of organizations are start ing to think in terms of business processes. Processes are at the very heart of each business, and must be understood and carried out by a wide range of actors, from both technical and non-technical backgrounds alike. When embracing digital transformation practices, there is a need for all involved parties to be aware of the underlying business processes in an organization. However, the representational complexity and biases of the state-of-the-art modeling notations pose a challenge in understandability. On the other hand, plain language representations, accessible by nature and easily understood by everyone, are often frowned upon by technical specialists due to their ambiguity. The aim of this thesis is precisely to bridge this gap: Between the world of the techni cal, formal languages and the world of simpler, accessible natural languages. Structured as an article compendium, in this thesis we present four main contributions to address specific problems in the intersection between the fields of natural language processing and business process management.
A l’era de la transformació digital, cada vegada més organitzacions comencen a pensar en termes de processos de negoci. Els processos són el nucli principal de tota empresa i, com a tals, han de ser fàcilment comprensibles per un ampli ventall de rols, tant perfils tècnics com no-tècnics. Quan s’adopta la transformació digital, és necessari que totes les parts involucrades estiguin ben informades sobre els protocols implantats com a part del procés de digitalització. Tot i això, la complexitat i biaixos de representació dels llenguatges de modelització que actualment conformen l’estat de l’art sovint en dificulten la seva com prensió. D’altra banda, les representacions basades en documentació usant llenguatge natural, accessibles per naturalesa i fàcilment comprensibles per tothom, moltes vegades són vistes com un problema pels perfils més tècnics a causa de la presència d’ambigüitats en els textos. L’objectiu d’aquesta tesi és precisament el de superar aquesta distància: La distància entre el món dels llenguatges tècnics i formals amb el dels llenguatges naturals, més accessibles i senzills. Amb una estructura de compendi d’articles, en aquesta tesi presentem quatre grans línies de recerca per adreçar problemes específics en aquesta intersecció entre les tecnologies d’anàlisi de llenguatge natural i la gestió dels processos de negoci.

Texte intégral
Résumé :
This thesis explores how the changing masculinities of the 21st century have affected how young men connect to musical theatre as a genre that has been stereotypically seen as gay. The investigation is first located in the theoretical framework of masculinities, utilising the concepts of the male sex role, hegemonic masculinities and inclusive masculinity to chart how the performance of the male gender has changed over the past century. The project then adopts an empirical approach to a group of 161 men and 25 women, establishing a methodological framework for correlating sexual orientation with attitudes towards musical theatre. There is a further honing of this methodology through the adoption of Jenifer Toksvig's 'The Fairytale Moment' exercise, which identifies how each participant connects to narrative through a core emotional drive. Finally, this data is tested through three case studies of how individual participants connect to 'Les Misérables', 'Wicked' and 'Soho Cinders', concluding that the emotional content of musical theatre is now as desirable to straight men as it is to women and LGBT men.

Résumé :
This thesis explores the automatic extraction of musical information from live performances - with the intention of using that information to create novel, responsive and adaptive performance tools for musicians. We focus specifically on two forms of musical analysis - harmonic analysis and beat tracking. We present two harmonic analysis algorithms - specifically we present a novel chroma vector analysis technique which we later use as the input for a chord recognition algorithm. We also present a real-time beat tracker, based upon an extension of state of the art non-causal models, that is computationally efficient and capable of strong performance compared to other models. Furthermore, through a modular study of several beat tracking algorithms we attempt to establish methods to improve beat tracking and apply these lessons to our model. Building upon this work, we show that these analyses can be combined to create a beat-synchronous musical representation, with harmonic information segmented at the level of the beat. We present a number of ways of calculating these representations and discuss their relative merits. We proceed by introducing a technique, which we call Performance Following, for recognising repeated patterns in live musical performances. Through examining the real-time beat-synchronous musical representation, this technique makes predictions of future harmonic content in musical performances with no prior knowledge in the form of a score. Finally, we present a number of potential applications for live performances that incorporate the real-time musical analysis techniques outlined previously. The applications presented include audio effects informed by beat tracking, a technique for synchronising video to a live performance, the use of harmonic information to control visual displays and an automatic accompaniment system based upon our performance following technique.

Résumé :
"This study is predicated on a strong belief that the gender make-up of African parliamnets must relfect the gender demographics of African states. It is only when that is achieved that the concepts of equality, non-discrimination and democracy can gain their true meaning. As a departure point, the study makes a case that statistically women are under-represented across the overwhelming majority of African parliaments. The study asserts that the under-representation is prevalent amid the existence of international, regional and domestic instruments, all providing for women's right to representation in decision-making processes. Thus, the study demonstrates that there is a gap between de jure and de facto representation. The study then argues that the convoluted ideology of patriarchy, sacrosanct cultures, inviolable religions, the constructed public/private dichotomy, low levels of education, and the negative impact of globalisation all act in concert to deny African women their rightful place in decision-making institutions, particluarly parliaments. In a bid to investigate how this can be reserved, the study explores the Rwandan and South African models for purposes of gaining insights on how they have contrived to reach and surpass the critical mass of women in their parliaments. These two models demonstrate that a combination of temporary special measures and gender mainstreaming are effective tools for emancipating women and ensuring their representation in parliaments. These have to be buttressed by strong legal and institutioanl frameworks, which operate in a conducive socio-political environment." -- Abstract.

AbstractUsing three photobooks by Ricardo Cases, Allison Stewart, and Stephen Gill, I explore the question of whether visual lists can exist. I investigate what operations must be involved in conceptualizing a semantically open and polysemous artifact like photography as a discrete enumeration and then consider which aesthetic practices might be associated with it. My thesis is that, through reductionist and abstracting practices, enumerative photography has found a way to rethink the problem of figural representation in documentary photography. As a serial work, the Conceptual Documentary photobook (CDp) can be both politically and conceptually coherent in emphasizing the interpretive gaps between individual images and thus creating a receptive autonomy, which is an important representational goal in approaches to Postdocumentary Art.

This chapter gives a summary of recent works on interpreting deep generative models. The methods are categorized into the supervised, the unsupervised, and the embedding-guided approaches. We will see how the human-understandable concepts that emerge in the learned representation can be identified and used for interactive image generation and editing.

Résumé :
AbstractUsing appropriate diagrams is generally considered efficacious in communication. However, although diagrams are extensively used in printed and digital media, people in general rarely construct diagrams to use in common everyday communication. Furthermore, instruction on diagram use for communicative purposes is uncommon in formal education and, when students are required to communicate what they have learned, the usual expectation is they will use words – not diagrams. Requiring diagram inclusion in essays, for example, would be almost unheard of. Consequently, current understanding about student capabilities in this area is very limited. The aim of this study therefore was to contribute to addressing this gap: it comprised a qualitative exploration of 12 undergraduate students’ diagram use in two essays (in which they were asked to include at least one diagram). Analysis focused on identifying the kinds of diagrams produced, and the effectiveness with which those diagrams were used. Useful functions that the diagrams served included clarification, summarization, integration of points, and provision of additional information and/or perspectives in visual form. However, there were also redundancies, as well as unclear, schematically erroneous, and overly complicated representations in some of the diagrams that the students constructed. These findings are discussed in terms of needs, opportunities, and challenges in instructional provision.

Résumé :
The problems of verification and realizability are two central themes in the analysis of reactive systems. When multiagent systems are considered, these problems have natural analogues of existence (nonemptiness) of pure-strategy Nash equilibria and verification of pure-strategy Nash equilibria. Recently, this body of work has begun to include finite-horizon temporal goals. With finite-horizon temporal goals, there is a natural hierarchy of goal representation, ranging from deterministic finite automata (DFA), to nondeterministic finite automata (NFA), and to alternating finite automata (AFA), with a worst-case exponential gap between each successive representation. Previous works showed that the realizability problem with DFA goals was PSPACE-complete, while the realizability problem with temporal logic goals is in 2EXPTIME. In this work, we study both the realizability and the verification problems with respect to various goal representations. We first show that the realizability problem with NFA goals is EXPTIME-complete and with AFA goals is 2EXPTIME-complete, thus establishing strict complexity gaps between realizability with respect to DFA, NFA, and AFA goals. We then contrast these complexity gaps with the complexity of the verification problem, where we show that verification with respect to DFAs, NFA, and AFA goals is PSPACE-complete.

Résumé :
While Generative Adversarial Networks (GANs) have accelerated the use of generative modelling within the machine learning community, most of the adaptations of GANs are restricted to images. The use of GANs to generate clinical data has been rare due to the inability of GANs to faithfully capture the intrinsic relationships between features given a small amount of observational data. We hypothesize and verify that this challenge can be mitigated by incorporating rich domain knowledge in the form of expert advice in the generative process. Specifically, we propose human-allied GANs that uses correlation advice from humans to create synthetic clinical data. We construct a system that takes a symbolic representation of the expert advice and converts it into constraints on correlation of the features during the generative process. Our empirical evaluation demonstrates (a) the superiority of our approach over other GAN models, (b) the importance of incorporating advice over instance noise and (c) an initial framework for incorporation of privacy in our model while capturing the relationships between features.

Résumé :
Saliency prediction refers to the computational task of modeling overt attention. Social cues greatly influence our attention, consequently altering our eye movements and behavior. To emphasize the efficacy of such features, we present a neural model for integrating social cues and weighting their influences. Our model consists of two stages. During the first stage, we detect two social cues by following gaze, estimating gaze direction, and recognizing affect. These features are then transformed into spatiotemporal maps through image processing operations. The transformed representations are propagated to the second stage (GASP) where we explore various techniques of late fusion for integrating social cues and introduce two sub-networks for directing attention to relevant stimuli. Our experiments indicate that fusion approaches achieve better results for static integration methods, whereas non-fusion approaches for which the influence of each modality is unknown, result in better outcomes when coupled with recurrent models for dynamic saliency prediction. We show that gaze direction and affective representations contribute a prediction to ground-truth correspondence improvement of at least 5% compared to dynamic saliency models without social cues. Furthermore, affective representations improve GASP, supporting the necessity of considering affect-biased attention in predicting saliency.

Résumé :
Change detection and analysis (CDA) is an important research topic in the joint interpretation of spatial-temporal remote sensing images. The core of CDA is to effectively represent the difference and measure the difference degree between bi-temporal images. In this paper, we propose a novel difference representation learning network (DRLnet) and an effective optimization framework without any supervision. Difference measurement, difference representation learning and unsupervised clustering are combined as a single model, i.e., DRLnet, which is driven to learn clustering-friendly and discriminative difference representations (DRs) for different types of changes. Further, DRLnet is extended into a recurrent learning framework to update and reuse limited training samples and prevent the semantic gaps caused by the saltation in the number of change types from over-clustering stage to the desired one. Experimental results identify the effectiveness of the proposed framework.

Texte intégral
Résumé :
The flow of polymers in micromolding applications is dominated by shear stresses. At high flow velocities and small wall thicknesses, the shear rates can exceed the typical characterization scheme of 10,000 reciprocal seconds. Yet, the effective design of micromolded parts and micromolding processes requires a correct understanding of the flow dynamics. In this paper, analytical models assuming power law fluid behavior are developed and experimentally validated for wall thicknesses of 10, 20, and 100 micro meters. A design of experiments is conducted to consider the effect of wall thickness, channel width, melt temperature, and pressure on flow rate in an isothermal molding process. The results indicate that the power law model is a valid representation for viscous polymer flow in very thin gaps under isothermal conditions, though further work is required to validate the non-isothermal dynamics.

Résumé :
This rapid literature review collates evidence from academic, policy focussed and grey literature on progress on incorporating gender perspectives in peace operations since 2018, including the deployment of female peacekeepers, and the emerging issues in this field. Key messages that emerge from this review include: The focus on women’s participation in peace processes has led to several initiatives and efforts to promote increased representation, the multidimensional nature of the UN’s women, peace, and security (WPS) agenda is illustrative of the complexity of contemporary peace operations. The new and emergent issues in National Action Plans (NAP) on Women, Peace and Security. Critiques of Resolution 1325 suggest that while the resolution provides some examples of what a gender perspective means in the context of a peace agreement, it does not define what it means to apply a gender perspective to peace processes. Gender perspectives are largely absent from peace negotiations. Despite the evolution of this agenda, most contemporary peace processes are still top-down, elite-driven exercises that contribute to marginalisation and exclusion. Whilst there is high-level commitment towards the strategy and what it aims to achieve, institutional barriers, assumptions, and politics undermine its implementation. Key challenges identified in the literature, related to incorporating Gender Perspectives in Peace Operations include. Buy-in from leadership, Mandate and context, Gender and expertise, Terminology, Under-representation of women in peacekeeping. Meaningful participation, Gap between norms and provisions, and Practical/logistical/training issues in implementing the WPS agenda.

Résumé :
The role of neural network modeling in the learning сontent of special course “Foundations of Mathematic Informatics” was discussed. The course was developed for the students of technical universities – future IT-specialists and directed to breaking the gap between theoretic computer science and it’s applied applications: software, system and computing engineering. CoCalc was justified as a learning tool of mathematical informatics in general and neural network modeling in particular. The elements of technique of using CoCalc at studying topic “Neural network and pattern recognition” of the special course “Foundations of Mathematic Informatics” are shown. The program code was presented in a CofeeScript language, which implements the basic components of artificial neural network: neurons, synaptic connections, functions of activations (tangential, sigmoid, stepped) and their derivatives, methods of calculating the network`s weights, etc. The features of the Kolmogorov–Arnold representation theorem application were discussed for determination the architecture of multilayer neural networks. The implementation of the disjunctive logical element and approximation of an arbitrary function using a three-layer neural network were given as an examples. According to the simulation results, a conclusion was made as for the limits of the use of constructed networks, in which they retain their adequacy. The framework topics of individual research of the artificial neural networks is proposed.

Résumé :
Review question / Objective: This study will investigate the question: what is maternal morbidity from the perspective of women and people with pregnancy experience? The objectives of this study are to: 1. describe the conditions and events that WPPE conceptualize as maternal morbidities, 2. identify the themes that arise across WPPE’s experiences, such as regional and cultural differences and similarities, and 3. produce a schematic representation of how WPPE conceptualize maternal morbidity. Background: Maternal morbidity is primarily concerned with adverse pregnancy-related outcomes, excluding mortality, among the pregnant and postpartum population. Although presently a global concern, maternal morbidity was not always prioritized in healthcare and research. The increased attention towards maternal morbidity in recent decades was preceded by the initial prioritization of maternal mortality as the dominant indicator of maternal health, leading to its decreasing trend over the decades.(1) Standards of maternal care are no longer solely defined by preventing mortality; they now include preventing and better treatment of maternal morbidity to improve patient outcomes. However, there are no universally accepted criteria for describing maternal morbidity. Less evidence is available on the views of Women and People with Pregnancy Experience (WPPE), and a knowledge gap exists in conceptualizing maternal morbidity from their perspective.

Texte intégral
Résumé :
A hydrostratigraphic framework has been developed for southern Ontario consisting of 15 hydrostratigraphic units and 3 regional hydrochemical regimes. Using this framework, the 54 layer 3-D lithostratigraphic model has been converted into a 15 layer 3-D hydrostratigraphic model. Layers are expressed as either aquifer or aquitard based principally on hydrogeologic characteristics, in particular the permeability and the occurrence/absence of groundwater when intersected by a water well or petroleum well. Hydrostratigraphic aquifer units are sub-divided into up to three distinct hydrochemical regimes: brines (deep), brackish-saline sulphur water (intermediate), and fresh (shallow). The hydrostratigraphic unit assignment provides a standard nomenclature and definition for regional flow modelling of potable water and deeper fluids. Included in the model are: 1) 3-D hydrostratigraphic units, 2) 3-D hydrochemical fluid zones within aquifers, 3) 3-D representations of oil and natural gas reservoirs which form an integral part of the intermediate to deep groundwater regimes, 4) 3-D fluid level surfaces for deep Cambrian brines, for brines and fresh to sulphurous groundwater in the Guelph Aquifer, and the fresh to sulphurous groundwater of the Bass Islands Aquifer and Lucas-Dundee Aquifer, 5) inferred shallow karst, 6) base of fresh water, 7) Lockport Group TDS, and 8) the 3-D lithostratigraphy. The 3-D hydrostratigraphic model is derived from the lithostratigraphic layers of the published 3-D geological model. It is constructed using Leapfrog Works at 400 m grid scale and is distributed in a proprietary format with free viewer software as well as industry standard formats.

Texte intégral
Résumé :
A systematic approach to tree planting and management globally is hindered by the limited synthesis of information sources on tree uses and species priorities. To help address this, the authors ‘mined’ information from 23 online global and regional databases to assemble a list of the most frequent tree species deemed useful for planting according to database mentions, with a focus on tropical regions. Using a simple vote count approach for ranking species, we obtained a shortlist of 100 trees mentioned in at least 10 of our data sources (the ‘top-100’ species). A longer list of 830 trees that were mentioned at least five times was also compiled. Our ‘top-100’ list indicated that the family Fabaceae (syn. Leguminosae) was most common. The information associated with our mined data sources indicated that the ‘top-100’ list consisted of a complementary group of species of differing uses. These included the following: for wood (mostly for timber) and fuel production, human nutrition, animal fodder supply, and environmental service provision (varied services). Of these uses, wood was most frequently specified, with fuel and food use also highly important. Many of the ‘top-100’ species were assigned multiple uses. The majority of the ‘top-100’ species had weediness characteristics according to ‘attribute’ invasiveness databases that were also reviewed, thereby demonstrating potential environmental concerns associated with tree planting that need to be balanced against environmental and livelihood benefits. Less than half of the ‘top-100’ species were included in the OECD Scheme for the Certification of Forest Reproductive Material, thus supporting a view that lack of germplasm access is a common concern for trees. A comparison of the ‘top-100’ species with regionally-defined tree inventories indicated their diverse continental origins, as would be anticipated from a global analysis. However, compared to baseline expectations, some geographic regions were better represented than others. Our analysis assists in priority-setting for research and serves as a guide to practical tree planting initiatives. We stress that this ‘top-100’ list does not necessarily represent tree priorities for the future, but provides a starting point for also addressing representation gaps. Indeed, our primary concern going forward is with the latter.
