Improving Langscape's Text-based Language Identification Tool

Text-based language identification (LID) is the task of determining the language a piece of text\ud is written in. Although modem LID tools achieve high accuracy using the widely-accepted\ud n-gram method, there are several areas of LID that remain more difficult, particularly the task\ud of distinguishing between closely related languages. Langscape, a project of the University\ud of Maryland's Language Science Center, has an LID tool that uses a variation on the n-gram\ud method. In this thesis, 1 propose and test a modification to Langscape's LID tool to improve its\ud ability to distinguish between closely related languages

Neuroplasticity after Sexual Experience in the Nucleus Accumbens of Syrian hamsters

Research over the past three decades has demonstrated that many neural changes occur in response to rewarding stimuli and behavior. However, most of this research has focused on the changes that occur following drug use and their role in addiction. Less research has investigated the neural changes in response to everyday rewarding behaviors such as eating, exercising, and sexual behavior, and even less has explored whether these changes differ in male and female brains. The goal of this study was to investigate the changes in brain circuitry that occur in Syrian hamsters after exposure to sexual experiences and to identify any possible sex differences involved. Specifically, levels of delta FosB, a transcription factor that is important for long-term neural plasticity following rewarding experiences, was measured in the Nucleus Accumbens (NAc) as a way to quantify these neural changes. This study also aimed at investigating whether the efficiency with which hamsters mate is improved with experience, as measured by the time the hamsters are actively having sex and the amount of sex-related behaviors they perform. It was expected that sexual experiences would lead to an up-regulation of delta FosB in the NAc, that this up-regulation would not differ between the sexes, and that mating efficiency would improve with experience. The results demonstrated that sexual experience led to higher delta FosB levels in the NAc than controls, and that there were no differences in delta FosB levels between males and females of the same group. This study also found that mating efficiency was not improved with experience. The results obtained in this study suggest that the normal rewarding behavior of sexual experience leads to neuroplastic changes in the NAc of Syrian hamsters and that male and female Syrian hamsters likely have similar neuroplastic changes following sexual experiences. This research has the potential to provide a better understanding of how drugs of abuse take advantage of reward pathways, and eventually lead to better treatments for addiction

Arts Foundation-Photography

This course will introduce students to the fundamentals of fine art photography with the goal of developing artistic perception and a unique vision. Technical workshops will be scheduled outside of class to give students proficiency with the camera and darkroom. Slide lectures, readings, and work with Haverford’s photography collection will prepare students for critical discussion of their own work, as well as for critical analysis of another artist’s work in a final paper

Cross-Cultural Lament Traditions

This course surveys lament traditions, broadly defined, across a range of cultures. In this course we will read a selection of ancient, medieval, and early modern lament; taking Greek lament traditions as our starting point, we will conclude by examining the role of modern social media in the expression and sharing of grief. The focus of the course will be the rich traditions of lament and elegy in medieval and early modern Britain, Ireland, and Scandinavia.Topics to be considered include the relationship between gender and lament, the intersection of orality, performance, and literacy, the societal function and purpose of mourning rituals,restrictions on mourning, and the social role of the professional mourner in some cultures.While we will primarily be concerned with textual evidence, we will also listen to recordings of funeral laments, and consider the evidence for the modern decline of traditional mourning practices

Introduction to Economics

The course begins with introductory topics in microeconomics: the analysis of individual economic decision-making units, such as firms and households, and the market in which they exchange goods and services. We examine several market structures: perfect competition,monopolistic competition, monopoly, and oligopoly, before briefly discussing scenarios in which markets may fail, such as in the presence of externalities.We then turn to macroeconomics: the study of the economy as a whole. Focusing on the United States, we will survey topics such as unemployment, inflation, growth, and the tools used by governments to impact the economy. We will also discuss the role of monetary policyin trying to control inflation while encouraging robust economic growth
