The Human Touch: How Non-Expert Users Perceive, Interpret, And Fix Topic Models, Tak Yeon Lee, Alison Smith, Kevin Seppi, Niklas Elmqvist, Jordan Boyd-Graber, Leah Findlater

Faculty Publications

Topic modeling is a common tool for understanding large bodies of text, but is typically provided as a “take it or leave it” proposition. Incorporating human knowledge in unsupervised learning is a promising approach to create high-quality topic models. Existing interactive systems and modeling algorithms support a wide range of refinement operations to express feedback. However, these systems’ interactions are primarily driven by algorithmic convenience, ignoring users who may lack expertise in topic modeling. To better understand how non-expert users understand, assess, and refine topics, we conducted two user studies—an in-person interview study and an online crowdsourced study. These studies …

Estimating Parasite Host Range, Tad Dallas, Shan Huang, Charles Nunn, Andrew W. Park, John M. Drake

Faculty Publications

© 2017 The Author(s) Published by the Royal Society. All rights reserved. Estimating the number of host species that a parasite can infect (i.e. host range) provides key insights into the evolution of host specialism and is a central concept in disease ecology. Host range is rarely estimated in real systems, however, because variation in species relative abundance and the detection of rare species makes it challenging to confidently estimate host range. We applied a non-parametric richness indicator to estimate host range in simulated and empirical data, allowing us to assess the influence of sampling heterogeneity and data completeness. After …

Position statement

The International Society of Sports Nutrition (ISSN) provides an objective and critical review regarding the timing of macronutrients in reference to healthy, exercising adults and in particular highly trained individuals on exercise performance and body composition. The following points summarize the position of the ISSN.

1. Nutrient timing incorporates the use of methodical planning and eating of whole foods, fortified foods and dietary supplements. The timing of energy intake and the ratio of certain ingested macronutrients may enhance recovery and tissue repair, augment muscle protein synthesis (MPS), and improve mood states following high-volume or intense exercise.
2. Endogenous glycogen stores …

Epigenetic Response Of Imprinted Domains During Carcinogenesis, Corey L. Bretz, Ingeborg M. Langohr, Joomyeong Kim

Faculty Publications

© 2017 The Author(s). Background: Imprinted domains have been identified as targets for aberrant DNA methylation during carcinogenesis, but it remains unclear when these epigenetic alterations occur and how they contribute to tumor progression. Epigenetic instability at key cis-regulatory elements within imprinted domains can concomitantly activate proto-oncogenes and turn off tumor suppressor genes. Thus, to further characterize the epigenetic response of imprinted domains during carcinogenesis, we compared the stability of DNA methylation at a variety of cis-regulatory elements within imprinted domains in two fundamentally different mouse tumors, benign and malignant, induced by the KrasG12D mutation. Results: We report that imprinted …

Altered Sensitivity To Social Gaze In The Fmr1 Premutation And Pragmatic Language Competence, Jessica Klusek, Joseph Schmidt, Amanda J. Fairchild, Ann Porter, Jane E. Roberts

Faculty Publications

Background: The FMR1 premutation affects 1:291 women and is associated with a range of cognitive, affective, and physical health complications, including deficits in pragmatic language (i.e., social language). This study investigated attention to eye gaze as a fundamental social-cognitive skill that may be impaired in the FMR1 premutation and could underlie pragmatic deficits. Given the high prevalence of the FMR1 premutation, efforts to define its phenotype and mechanistic underpinnings have significant public health implications. Methods: Thirty-five women with the FMR1 premutation and 20 control women completed an eye-tracking paradigm that recorded time spent dwelling within the eye region in response …

Multiphysics Simulation Of Low-Amplitude Acoustic Wave Detection By Piezoelectric Wafer Active Sensors Validated By In-Situ Ae-Fatigue Experiment, Yeasin Bhuiyan, Victor Giurgiutiu

Faculty Publications

Piezoelectric wafer active sensors (PWAS) are commonly used for detecting Lamb waves for structural health monitoring application. However, in most applications of active sensing, the signals are of high-amplitude and easy to detect. In this article, we have shown a new avenue of using the PWAS transducer for detecting the low-amplitude fatigue-crack related acoustic emission (AE) signals. Multiphysics finite element (FE) simulations were performed with two PWAS transducers bonded to the structure. Various configurations of the sensors were studied by using the simulations. One PWAS was placed near to the fatigue-crack and the other one was placed at a certain …

Reproductive And Metabolic State Differences In Olfactory Responses To Amino Acids In A Mouth Brooding African Cichlid Fish, Alexandre A. Nikonov, Julie M. Butler, Karen E. Field, John Caprio, Karen P. Maruska

Faculty Publications

© 2017. Published by The Company of Biologists Ltd | Journal of Experimental Biology. Olfaction mediates many crucial life-history behaviors such as prey detection, predator avoidance, migration and reproduction. Olfactory function can also be modulated by an animal's internal physiological and metabolic states. While this is relatively well studied in mammals, little is known about how internal state impacts olfaction in fishes, the largest and most diverse group of vertebrates. Here we apply electroolfactograms (EOGs) in the African cichlid fish Astatotilapia burtoni to test the hypothesis that olfactory responses to food-related cues (i.e. L-amino acids; alanine and arginine) vary with …

Faculty Publications

We aimed to examine the association between the Alternative Healthy Eating Index updated in 2010 (AHEI-2010), the Dietary Inflammatory Index (DIITM) and risk of mortality in the Whitehall II study. We also conducted a meta-analysis on the DII-based results from previous studies to summarise the overall evidence. Data on dietary behaviour assessed by self-administered repeated FFQ and on mortality status were available for 7627 participants from the Whitehall II cohort. Cox proportional hazards regression models were performed to assess the association between cumulative average of AHEI-2010 and DII scores and mortality risk. During 22 years of follow-up, 1001 participants died …

Listeria Occurrence In Poultry Flocks: Detection And Potential Implications, Michael J. Rothrock Jr., Morgan L. Davis, Aude Locatelli, Aaron Bodie, Tori G. Mcintosh, Janet R. Donaldson, Steven C. Ricke

Faculty Publications

Foodborne pathogens such as Salmonella, Campylobacter, Escherichia coli, and Listeria are a major concern within the food industry due to their pathogenic potential to cause infection. Of these, Listeria monocytogenes, possesses a high mortality rate (approximately 20%) and is considered one of the most dangerous foodborne pathogens. Although the usual reservoirs for Listeria transmission have been extensively studied, little is known about the relationship between Listeria and live poultry production. Sporadic and isolated cases of listeriosis have been attributed to poultry production and Listeria spp. have been isolated from all stages of poultry production and processing. Farm studies …

If Gandhi Was Your Marriage Therapist, Jason B. Whiting

Faculty Publications

Mohandas Gandhi was born in India in 1869. As a young man he left to study law in Great Britain, and later he moved with his wife and children to South Africa, where he began a legal practice. There he experienced painful discrimination and abuse, and once was beaten by a stagecoach driver for refusing to give up his seat for a European. This galvanized Gandhi’s resolve to fight injustice through principles of satyagraha (“truth and firmness”) he had learned from his mother.

Future Orientation, Social Support, And Psychological Adjustment Among Left-Behind Children In Rural China: A Longitudinal Study, Shaobing Su, Xiaoming Li, Danhua Lin, Maoling Zhu

Faculty Publications

Existing research has found that parental migration may negatively impact the psychological adjustment of left-behind children. However, limited longitudinal research has examined if and how future orientation (individual protective factor) and social support (contextual protective factor) are associated with the indicators of psychological adjustment (i.e., life satisfaction, school satisfaction, happiness, and loneliness) of left-behind children. In the current longitudinal study, we examined the differences in psychological adjustment between left-behind children and non-left behind children (comparison children) in rural areas, and explored the protective roles of future orientation and social support on the immediate (cross-sectional effects) and subsequent (lagged effects) status …

© 2017 The Author(s). Using nationwide survey data, we investigate U.S. meat goat producer preferences and willingness to pay for meat goat breeding stock attributes. Discrete choice experiments were employed, and mixed logit and latent class models were used for analysis. Results showed that producers preferred animals that were highly masculine/feminine, had good structure and soundness, and were of the Boer breed, whereas they preferred fewer animals that were older, of Kiko and Spanish breeds, and priced higher. Significant preference heterogeneity was found among the respondents. Larger-scale producers had greater preference for high masculinity/femininity, good structure and soundness, and Boer …

Retinoic Acid Inhibits White Adipogenesis By Disrupting Gadd45a-Mediated Zfp423 Dna Demethylation, Bo Wang, Xing Fu, Mei Jun Zhu, Min Du

Faculty Publications

© The Author (2017). Retinoic acid (RA), a bioactive metabolite of Vitamin A, is a critical mediator of cell differentiation. RA blocks adipogenesis, but mechanisms remain to be established. ZFP423 is a key transcription factor maintaining white adipose identity. We found that RA inhibits Zfp423 expression and adipogenesis via blocking DNA demethylation in the promoter of Zfp423, a process mediated by growth arrest and DNA-damage-inducible protein alpha (GADD45A). RA induces the partnering between retinoic acid receptor (RAR) and tumor suppressor inhibitor of growth protein 1 (ING1), which prevents the formation of GADD45A and ING1 complex necessary for locus-specific Zfp423 DNA …

Varietal Preferences And Within-Orchard And Tree Distribution Of Newly Recorded Gall Midges, Dasineura Amaramanjarae And Procontarinia Mangiferae (Diptera: Cecidomyiidae), From Commercial Mango Cultivars In Pakistan, H. M. Rehman, R. Mahmood, M. Razaq, R. Saeed, M. Jamil, G. V.P. Reddy

Faculty Publications

Gall midges (Diptera: Cecidomyiidae) damage mango by feeding on flowers and fruit tissues, inducing galls on leaves, and providing inoculums of anthracnose. Dasineura amaramanjarae Grover and Procontarinia mangiferae (Felt), two gall midges that damage flowers in all mango-growing areas of the world, have recently been recorded in Pakistan, and studies were conducted in 2011 and 2012 on the within-tree and orchard distribution patterns and cultivar preference of both species in Pakistan at one location (Rahim Yar Khan). Both gall midge species were found on all mango cultivars examined (Chaunsa, Fajri, Dusehri, Surkha, Sindhri, and Anwar Ratul), with the most damage …

Role Of The Aphid Species And Their Feeding Locations In Parasitization Behavior Of Aphelinus Abdominalis, A Parasitoid Of The Lettuce Aphid Nasonovia Ribisnigri, Govinda Shrestha, Henrik Skovgård, Gadi V.P. Reddy, Tove Steenberg, Annie Enkegaard

Faculty Publications

Aphid species feeding on lettuce occupy distinct feeding sites: the lettuce aphid Nasonovia ribisnigri prefers to feed on heart leaves, whereas the potato aphid Macrosiphum euphorbiae feeds only on outer leaves. The aphid parasitoid Aphelinus abdominalis, known to be able to regulate M. euphorbiae on many crops, has recently been indicated as a promising biocontrol candidate also for use against N. ribisnigri, a major pest of lettuce. This study therefore examined A. abdominalis parasitization preference between N. ribisnigri and M. euphorbiae and its ability to parasitize aphids feeding on different parts of lettuce plants. In addition, life history traits of …

Economic Growth And Mortality: Do Social Protection Policies Matter?, Usama Bilal, Richard Cooper, Francis Abreu, Claudia Nau, Manuel Franco, Thomas A. Glass

Faculty Publications

Background: In the 20th century, periods of macroeconomic growth have been associated with increases in population mortality. Factors that cause or mitigate this association are not well understood. Evidence suggests that social policy may buffer the deleterious impact of economic growth. We sought to explore associations between changing unemployment (as a proxy for economic change) and trends in mortality over 30 years in the context of varying social protection expenditures. Methods: We model change in all-cause mortality in 21 OECD (Organization for Economic Cooperation and Development) countries from 1980 to 2010. Data from the Comparative Welfare States Data Set and …

Low-Income Childless Young Adults' Marriage And Fertility Frameworks, Heather M. Rackin, Christina M. Gibson-Davis

Faculty Publications

The authors investigated how low-income young adults without children understand marriage and fertility. Data come from the Becoming Partners and Parents Study (N = 69), a qualitative study of African American adults aged 18 to 22 in a mid-size southern city. This is the first study to analyze young, low-income, childless, and unmarried Black respondents' frameworks (i.e., internal understandings of the world) of marriage and fertility. In contrast to research conducted on parents, this research on childless adults indicated a narrative in which there were close connections between marriage and fertility and an economic bar adhered to both marriage and …

Genistein Crosses The Bioartificial Oviduct And Alters Secretion Composition, Constantine A. Simintiras, Roger G. Sturmey

Faculty Publications

The dietary derived isoflavone and oestrogen analogue, genistein, is known to perturb fundamental reproductive events such as implantation and embryo cleavage. However the question of whether genistein is able to traverse the oviduct epithelial monolayer and impact oviduct fluid secretion remains unclear. This study tests these research questions using a bioartificial oviduct to show that genistein permeates the oviduct lumen in vitro with a biphasic (burst and plateau) kinetic profile, faster than spontaneous diffusion, and alters the amino acid composition of in vitro derived oviduct fluid (ivDOF) but not as an oestrogen analogue. In addition to offering insights into the …

Oviposition Preference And Offspring Performance In Container Breeding Mosquitoes: Evaluating The Effects Of Organic Compounds And Laboratory Colonisation, David W. Allgood, Donald A. Yee

Faculty Publications

1. The preference–performance hypothesis (PPH) predicts that organisms lacking parental care should oviposit in habitats that optimise offspring performance. Preference–performance relationships were investigated for the Asian tiger mosquito (Aedes albopictus Skuse) and the southern house mosquito (Culex quinquefasciatus Say) (Diptera: Culicidae), two medically important container-breeding species, in response to an organic chemical blend mimicking decaying plant matter. Additionally, the effects of long-term laboratory colonisation of Cx. quinquefasciatus using wild and laboratory strains were evaluated.

2. Oviposition bioassays were conducted by releasing gravid mosquitoes into field enclosures with automobile tires containing low and high concentrations of the chemical blend, …
