Context-Aware Prediction of Derivational Word-forms

Derivational morphology is a fundamental and complex characteristic of language. In this paper we propose the new task of predicting the derivational form of a given base-form lemma that is appropriate for a given context. We present an encoder--decoder style neural network to produce a derived form character-by-character, based on its corresponding character-level representation of the base form and the context. We demonstrate that our model is able to generate valid context-sensitive derivations from known base forms, but is less accurate under a lexicon agnostic setting

Overview: Computer vision and machine learning for microstructural characterization and analysis

The characterization and analysis of microstructure is the foundation of microstructural science, connecting the materials structure to its composition, process history, and properties. Microstructural quantification traditionally involves a human deciding a priori what to measure and then devising a purpose-built method for doing so. However, recent advances in data science, including computer vision (CV) and machine learning (ML) offer new approaches to extracting information from microstructural images. This overview surveys CV approaches to numerically encode the visual information contained in a microstructural image, which then provides input to supervised or unsupervised ML algorithms that find associations and trends in the high-dimensional image representation. CV/ML systems for microstructural characterization and analysis span the taxonomy of image analysis tasks, including image classification, semantic segmentation, object detection, and instance segmentation. These tools enable new approaches to microstructural analysis, including the development of new, rich visual metrics and the discovery of processing-microstructure-property relationships.Comment: submitted to Materials and Metallurgical Transactions

Spot Pyrometer Analysis and System Design

The primary goal of this project was to design and construct a spot pyrometer for Analog Devices, Inc. We examined commercially available remote temperature sensors to determine their operating characteristics and we evaluated individual IR sensors. We designed, constructed, and calibrated our own spot pyrometer using a thermopile sensor, analog to digital converter, and a USB interface, meeting our specifications

Behavioural economics, motivating psycho-education improvements; a mobile technology initiative in South Africa

Here we report on a health behavioural support project, using incentivised behaviour on a mobile platform through M4JAM. This was a proof of concept study to support further developments, more specifically targeted at the management of Tuberculosis and Human Immunodeficiency Virus. The study reported here examines the impact of financial rewards and app towards improving mental health outcomes in South Africa. 136 participants were recruited from a database and dichotomized into self-determined and heteronomous groups based on self-report scores. Overall the findings highlighted that personal financial incentives have a role in motivating behaviour and that individuals with higher levels of self-determinate motivation. The findings are discussed in light of the usefulness of an incentivized mobile platform in real-world practice to encourage mental health improvements in a low to middle-income countries

A photograph of four orientalists (Bombay, 1885): knowledge production, religious identities, and the negotiation of invisible conflicts

Abstract By analyzing the history of a photograph taken in a Bombay photo studio in 1885, this article explores notions of the production of knowledge on India and cultural dialogues, encounters, appropriations, and conflicts in colonial British India in the late nineteenth century. The photograph was taken after a Hindu religious ceremony in honour of the Italian Sanskritist Angelo de Gubernatis. Dressed as a Hindu Brahman, he is the only European photographed next to three Indian scholars, but what the image suggests of encounter and hybridity was challenged by the many written texts that reveal the conflicting dialogues that took place before and after the portrait was taken. Several factors were examined in order to decide who should and who should not be in the photograph: religion, cast, and even gender were successively discussed, before the category of “knowledge” became the bond that unified the four men who studied, taught, and wrote on India

Voluntary workplace genomic testing: wellness benefit or Pandora\u27s box?

Consumer interest in genetic and genomic testing is growing rapidly, with more than 26 million Americans having purchased direct-to-consumer genetic testing services. Capitalizing on the increasing comfort of consumers with genetic testing outside the clinical environment, commercial vendors are expanding their customer base by marketing genetic and genomic testing services, including testing for pharmacogenomic and pathogenic variants, to employers for inclusion in workplace wellness programs. We describe the appeal of voluntary workplace genomic testing (wGT) to employers and employees, how the ethical, legal, and social implications literature has approached the issue of genetic testing in the workplace in the past, and outline the relevant legal landscape. Given that we are in the early stages of development of the wGT market, now is the time to identify the critical interests and concerns of employees and employers, so that governance can develop and evolve along with the wGT market, rather than behind it, and be based on data, rather than speculative hopes and fears
