Forecasting The Onset And Course Of Mental Illness With Twitter Data, Andrew G. Reece, Andrew J. Reagan, Katharina L.M. Lix, Peter Sheridan Dodds, Christopher M. Danforth, Ellen J. Langer

College of Engineering and Mathematical Sciences Faculty Publications

We developed computational models to predict the emergence of depression and Post-Traumatic Stress Disorder in Twitter users. Twitter data and details of depression history were collected from 204 individuals (105 depressed, 99 healthy). We extracted predictive features measuring affect, linguistic style, and context from participant tweets (N = 279,951) and built models using these features with supervised learning algorithms. Resulting models successfully discriminated between depressed and healthy content, and compared favorably to general practitioners' average success rates in diagnosing depression, albeit in a separate population. Results held even when the analysis was restricted to content posted before first depression diagnosis. …

In the section Method, subsection Improving data quality, the sentence ‘We also excluded participants with CES-D scores of 22 or higher. should read as We also excluded participants with CES-D scores of 21 or lower. This has now been acknowledged and corrected in this erratum. …

Instagram Photos Reveal Predictive Markers Of Depression, Andrew G. Reece, Christopher M. Danforth

College of Engineering and Mathematical Sciences Faculty Publications

Using Instagram data from 166 individuals, we applied machine learning tools to successfully identify markers of depression. Statistical features were computationally extracted from 43,950 participant Instagram photos, using color analysis, metadata components, and algorithmic face detection. Resulting models outperformed general practitioners’ average unassisted diagnostic success rate for depression. These results held even when the analysis was restricted to posts made before depressed individuals were first diagnosed. Human ratings of photo attributes (happy, sad, etc.) were weaker predictors of depression, and were uncorrelated with computationally-generated features. These results suggest new avenues for early screening and detection of mental illness.

Sentiment Analysis Methods For Understanding Large-Scale Texts: A Case For Using Continuum-Scored Words And Word Shift Graphs, Andrew J. Reagan, Christopher M. Danforth, Brian Tivnan, Jake Ryland Williams, Peter Sheridan Dodds

College of Engineering and Mathematical Sciences Faculty Publications

The emergence and global adoption of social media has rendered possible the real-time estimation of population-scale sentiment, an extraordinary capacity which has profound implications for our understanding of human behavior. Given the growing assortment of sentiment-measuring instruments, it is imperative to understand which aspects of sentiment dictionaries contribute to both their classification accuracy and their ability to provide richer understanding of texts. Here, we perform detailed, quantitative tests and qualitative assessments of 6 dictionary-based methods applied to 4 different corpora, and briefly examine a further 20 methods. We show that while inappropriate for sentences, dictionary-based methods are generally robust in …

Evaluating Spatial Variability In Sediment And Phosphorus Concentration-Discharge Relationships Using Bayesian Inference And Self-Organizing Maps, Kristen L. Underwood, Donna M. Rizzo, Andrew W. Schroth, Mandar M. Dewoolkar

College of Engineering and Mathematical Sciences Faculty Publications

Given the variable biogeochemical, physical, and hydrological processes driving fluvial sediment and nutrient export, the water science and management communities need data-driven methods to identify regions prone to production and transport under variable hydrometeorological conditions. We use Bayesian analysis to segment concentration-discharge linear regression models for total suspended solids (TSS) and particulate and dissolved phosphorus (PP, DP) using 22 years of monitoring data from 18 Lake Champlain watersheds. Bayesian inference was leveraged to estimate segmented regression model parameters and identify threshold position. The identified threshold positions demonstrated a considerable range below and above the median discharge—which has been used previously …

Upstream Watershed Condition Predicts Rural Children's Health Across 35 Developing Countries, Diego Herrera, Alicia Ellis, Brendan Fisher, Christopher D. Golden, Kiersten Johnson, Mark Mulligan, Alexander Pfaff, Timothy Treuer, Taylor H. Ricketts

Rubenstein School of Environment and Natural Resources Faculty Publications

Diarrheal disease (DD) due to contaminated water is a major cause of child mortality globally. Forests and wetlands can provide ecosystem services that help maintain water quality. To understand the connections between land cover and childhood DD, we compiled a database of 293,362 children in 35 countries with information on health, socioeconomic factors, climate, and watershed condition. Using hierarchical models, here we find that higher upstream tree cover is associated with lower probability of DD downstream. This effect is significant for rural households but not for urban households, suggesting differing dependence on watershed conditions. In rural areas, the effect of …

Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore

Psychology Faculty Publications

Attentional bias to alcohol-related stimuli is believed to be an important contributor to the development and maintenance of drug abuse. There is a considerable body of research examining attentional bias, much of which has typically utilized image-display tasks as a means to assess the phenomenon. Little, however, is known about the nature of this bias in an individual’s natural environment. The current study sought to implement a novel approach to assessing attentional bias in vivo. Participants wore portable eye-tracking glasses that recorded video from their point of view and measured fixation time to objects they observed. They entered a room …

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Effects Of Environmental Enrichment On Self-Administration Of The Short-Acting Opioid Remifentanil In Male Rats, Rebecca S. Hofford, Jonathan J. Chow, Joshua S. Beckmann, Michael T. Bardo

Psychology Faculty Publications

Background

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil.

Methods

Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of …

Negative Outcomes Of Teen Sexual Activity: Is There A Regional Effect?, Hannah Latta, Said Shahtahmasebi, Hatim A. Omar

Pediatrics Faculty Publications

A recent victory with respect to teen sexual behavior is the reduction of the national teen birth rate. In 1991, there were 61.8 births per 1000 females aged 15-19. By 2014, this rate plummeted to 24.2 births per 1000 adolescent females. Averages, however, do not reflect state-level variation. For example, in 2014, Kentucky reported 35.3 births per 1000 adolescent females, while New York reported a teen birth rates of 16.1 births per 1000 adolescent females. This report asks: are these discrepancies due to regional factors, and are these differences statistically significant? To examine rural and urban differences in outcomes of …

Portraits, Preservation & Pedigrees: An Introduction To Photographic Portraiture, Photographs As A Means Of Genealogical Research, And A Preservation Case Study Of The Howard D. Beach Studio Collection Of Glass Plate Negatives, Kirsten Feigel

Museum Studies Theses

Photography is an established art form that combines the knowledge of chemistry, light, and optics to render an image. Initially, the image is captured on a flat surface coated with emulsion and combined with an exposure to sunlight or another illuminating source. Today, images are captured by digital methods. Artistically, the photograph may reveal sceneries of landscapes, of treasured belongings and of people, as they are seen to the human eye. Photographic portraiture is the oldest style of photography next to landscape imagery, due to commercial photographers setting up studios and experimenting with photography’s many cameras, plates, and emulsions. In …

Higher And Lower Order Factor Analyses Of The Temperament In Middle Childhood Questionnaire., Yuliya Kotelnikova, Thomas M Olino, Daniel N Klein, Sarah V M Mackrell, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

The Temperament in Middle Childhood Questionnaire (TMCQ) is a widely used parent-report measure of temperament. However, neither its lower nor higher order structures has been tested via a bottom-up, empirically based approach. We conducted higher and lower order exploratory factor analyses (EFAs) of the TMCQ in a large ( N = 654) sample of 9-year-olds. Item-level EFAs identified 92 items as suitable (i.e., with loadings ≥.40) for constructing lower order factors, only half of which resembled a TMCQ scale posited by the measure's authors. Higher order EFAs of the lower order factors showed that a three-factor structure (Impulsivity/Negative Affectivity, Negative …

Prismatic Blade Production In The Lower Cacaulapa Valley, Honduras: Implications For A Late Classic Political Economy, William J. Mcfarlane, Edward M. Schortman

Anthropology Papers and Presentations

Investigations of ancient political economies frequently focus on craft production. How manufacturing is organized can provide critical insights on more than the economy because social interactions and political processes are also involved. Here we consider how the acquisition, fabrication, and distribution of obsidian blades figured in the political strategies of craftworkers and elites within the Late Classic (AD 600–800) lower Cacaulapa Valley, northwestern Honduras. This evidence provides insights into the organization of craft manufacture across southeastern Mesoamerica and suggests that current models do not capture the varied production strategies that may be pursued within the same polity.

Morphologically-Directed Raman Spectroscopy For Forensic Soil Analysis, Brooke Weinger Kammrath, Andrew Koutrakos, Josemar A. Castillo, Cathryn Langley, Debbie Huck-Jones

Forensic Science Publications

Morphologically-directed Raman spectroscopy (MDRS) is a novel yet reliable analytical technique that can be used for a variety of forensic applications, enabling scientists to gain more information from samples than they obtain using more traditional methods. In soil forensics, MDRS delivers particle size distribution and microscopic morphological characteristics for the particles present, and at the same time allows secure mineral identification. In this article, we explore the benefits of utilizing soil in forensic investigations, and demonstrate the value of applying MDRS. Two case studies illustrate the real-life potential and applications of this technology.

Russian Foreign Policy And National Identity, Monica Hanson-Green

Senior Honors Theses

National identity provides the interpretive framework through which foreign policy makers understand their role in the world and the actions of other states, and can also be utilized as a tool to mobilize public support behind foreign policy maneuvers. Foreign policy in turn is both shaped by constructions of national identity, and often used to forge and substantiate the narratives of national identity which best serve the regime’s domestic interests. This thesis will seek to establish the mutually constitutive relationship between national identity and foreign policy through an analysis of the interaction of these elements in the Russian Federation under …

Innovation Influences Liking For Chocolates Among Neophilic Consumers, Christopher R. Loss, Debra Zellner, Francisco Migoya

Department of Psychology Faculty Scholarship and Creative Works

The fear of trying new foods is a major barrier for entry for innovative ingredients, foods, flavors, or cuisines into the market place. We explored the relationship between perceived innovation and liking for chocolates and degree of neophobia. Line scales were used to measure: innovation, liking, and perceived dollar value for three chocolate confections. One was a traditional confection (palette d′or), and two others were designed to be more innovative (white miso with dark chocolate and white chocolate with candied black olive). An analysis of variance found that panelists (n=44) perceived significant (p<0.01) differences among the chocolates in innovation, and liking, but not dollar value or estimated caloric content. The chocolate rated as the most innovative was also rated as the least liked. This finding is significant since the mean neophobia score of our subjects was quite low and very few of them would have been classified as neophobic. This current work suggests that acceptance of innovative new foods is dependent, in part, upon factors that transcend neophobic mindsets. Chefs and product developers should be aware of the fact that even among neophilic consumers who are quite willing to consume novel foods, there is a possibility that a food might be too innovative, resulting in a negative impact on liking.
