Abstract:
The ultimate goal of any DSM is a scalable and accurate representation of lexical semantics. Recent developments due to Bullinaria &amp; Levy (2012) and Caron (2001) indicate that the accuracy of such models can be improved by redistribution of weight on the principal components. However, this method is poorly understood and barely replicated due to the computational expensive dimension reduction and the puzzling nature of the results.

Abstract:
Machine learning methods have been successfully used to analyse neuroimaging data for a variety of applications, including the classification of subjects with different brain disorders. However, most studies still rely on the labelling of the subjects, constraining the study of several brain diseases within a paradigm of pre-defined clinical labels, which have shown to be unreliable in some cases. The lack of understanding regarding the association between brain and behaviour presents itself as an interesting challenge for more exploratory machine learning approaches, which could potentially h

In parametrized continuous state-space models, one can obtain estimates of the likelihood of the data for fixed parameters via the Sequential Monte Carlo methodology. Unfortunately, even if the likelihood is continuous in the parameters, the estimates produced by practical particle filters are not, even when common random numbers are used for each filter. This is because the same resampling step which drastically reduces the variance of the estimates also introduces discontinuities in the particles that are selected across filters when the parameters change.

The present study was a systematic investigation of hierarchical skill sequences in the design copying domain. The factors associated with possible variations in task difficulty were delineated. Five hierarchies were developed to reflect variations in rule usage, the structuring of responses, presence of angles, spatial orientations, and stimulus complexity. Three-hundred thirty four subjects aged five through ten years were administered a 25 item design copying test. The data were analyzed using probabilistic models. Latent trait models were developed to test the hypothesized skill sequences.

The foundation for the work in this dissertation is built upon visualizing generative models' latent spaces to gain deeper understanding of data, analyze faults, and propose solutions.

Roll compaction is a continuous process commonly used in the pharmaceutical industry for dry granulation of moisture and heat sensitive powder blends. It is intended to increase bulk density and improve flowability. Roll compaction is a complex process that depends on many factors, such as feed powder properties, processing conditions and system layout. Some of the variability in the process remains unexplained. Accordingly, modeling tools are needed to understand the properties and the interrelations between raw materials, process parameters and the quality of the product. It is important to

Este artículo estudia el efecto del envejecimiento de los vecinos sobre las organizaciones locales en San Felipe, un barrio de clase media en Lima, Perú. Ilustro el efecto de este fenómeno usando el caso del control del espacio público en el barrio. Para esta investigación realicé observación participante durante un año. Durante ese año observé la dinámica de las asambleas locales, entrevisté a 46 vecinos de distintas características y observé una gran cantidad de situaciones y controversias entre vecinos en los espacios públicos de San Felipe. Encuentro que los adultos-mayores son los que imp

Abstract:
This study seeks to renew interest in the poetically constructed landscapes of Ovid’s Metamorphoses. Far from existing as mere background to the epic, close investigation and analysis reveals the reflective relationship and mutually exerted force between landscape and narrative. Detailed readings show how the landscapes are created in order to reveal Ovid’s poetic programme, especially as concerns the intersection of genre; landscape descriptions are read as interpretive strategies for understanding the crossing of genres that comprise Ovid’s hyper-Alexandrian epic. I argue for this interest a

Abstract:
<p> This project proposes to re-conceptualize the city of Buenos Aires through the works of three Argentine authors. This work will move away from a univocal understanding of the city, and will re-think Buenos Aires as a confluence of meanings that subjects navigate and negotiate daily to destabilize metanarratives of urban space. In this work, the tropes of the (in)visible and performance/movement will bridge the three chapters, challenging us to distance ourselves from the oversimplified understandings that rely heavily on the visual. As such, urban space will be seen as under construction b

Abstract:
Questions have been shown to aid in student understanding of mathematics, particularly "novel" questions (Mesa, Celis, & Lande, 2013) that do not have a predetermined answer. However, students do not always understand what is intended by questions posed by teachers, particularly those students who come from different cultural and lingual backgrounds than those dominant in the classroom discourse. This project investigated the relationship between how a mathematics teacher acknowledged students funds of knowledge in her questions and how Latina/o students responded. It shows some research based

Abstract:
Since 1994, Mexico has seen a proliferation of largely indigenous social movements asserting their right to land and territory, most notably within the southern part of the country. This thesis seeks to analyse why this has been the case by placing these movements within a theory of the production of space, and examining its role within the global political economy. It is submitted that events in southern Mexico can be explained as a clash between two distinct spatial projects; the spaces of capital on the one hand, and the spaces of resistance on the other. In order to make this argument, the
