Dog Movie Stars And Dog Breed Popularity: A Case Study In Media Influence On Choice, Stefano Ghirlanda, Alberto Acerbi, Harold Herzog

Publications and Research

Fashions and fads are important phenomena that influence many individual choices. They are ubiquitous in human societies, and have recently been used as a source of data to test models of cultural dynamics. Although a few statistical regularities have been observed in fashion cycles, their empirical characterization is still incomplete. Here we consider the impact of mass media on popular culture, showing that the release of movies featuring dogs is often associated with an increase in the popularity of featured breeds, for up to 10 years after movie release. We also find that a movie's impact on breed popularity correlates …

Mapping The Methods Of Composition/Rhetoric Dissertations: A “Landscape Plotted And Pieced”, Benjamin M. Miller

Publications and Research

What methods do graduate students take up for their dissertation projects? This article shares findings from distant reading of 2,711 abstracts, suggesting that humanist approaches predominate within the Consortium of Doctoral Programs in Rhetoric and Composition, but not without some methodological pluralism. A large number of studies outside the consortium are also considered.

Long-Term Cre-Mediated Retrograde Tagging Of Neurons Using A Novel Recombinant Pseudorabies Virus, Hysell V. Oviedo, Hassasna K. Oyibo, Petr Znamenskiy, Lynn W. Enquist, Anthony M. Zador

Publications and Research

Brain regions contain diverse populations of neurons that project to different long-range targets. The study of these subpopulations in circuit function and behavior requires a toolkit to characterize and manipulate their activity in vivo. We have developed a novel set of reagents based on Pseudorabies Virus (PRV) for efficient and long-term genetic tagging of neurons based on their projection targets. By deleting IE180, the master transcriptional regulator in the PRV genome, we have produced a mutant virus capable of infection and transgene expression in neurons but unable to replicate in or spread from those neurons. IE180-null mutants showed no cytotoxicity, …

Can Culture Justify Infant Circumcision?, Eldar Sarajlic

Publications and Research

The paper addresses arguments in the recent philosophical and bioethical literature claiming that social and cultural benefits can justify non-therapeutic male infant circumcision. It rejects these claims by referring to the open future argument, according to which infant circumcision is morally unjustifiable because it violates the child’s right to an open future. The paper also addresses an important objection to the open future argument and examines the strength of the objection to refute the application of the argument to the circumcision case.

Student Reading Practices In Print And Electronic Media, Nancy M. Foasberg

Publications and Research

This paper reports a diary-based qualitative study on college students’ reading habits with regard to print and electronic media. Students used a form to record information about their reading practices for twelve days, including length of reading event, location, format used, and the purpose of reading. Students tended to use print for academic and long-form reading and to engage with it more deeply. Although electronic resources were sometimes used for academic purposes, students often used them for shorter and nonacademic reading. Students found electronic media convenient, but most of them did not wish to switch to electronic media for their …

Enzymatic Oxidation Of Cholesterol: Properties And Functional Effects Of Cholestenone In Cell Membranes, Maarit Neuvonen, Moutusi Manna, Sini Mokkila, Matti Javanainen, Tomasz Rog, Zheng Liu, Robert Bittman, Ilpo Vattulainen, Elina Ikonen

Publications and Research

Bacterial cholesterol oxidase is commonly used as an experimental tool to reduce cellular cholesterol content. That the treatment also generates the poorly degradable metabolite 4-cholesten-3-one (cholestenone) has received less attention. Here, we investigated the membrane partitioning of cholestenone using simulations and cell biological experiments and assessed the functional effects of cholestenone in human cells. Atomistic simulations predicted that cholestenone reduces membrane order, undergoes faster flip-flop and desorbs more readily from membranes than cholesterol. In primary human fibroblasts, cholestenone was released from membranes to physiological extracellular acceptors more avidly than cholesterol, but without acceptors it remained in cells over a day. …

Audience Preferences Are Predicted By Temporal Reliability Of Neural Processing, Jacek P. Dmochowski, Matthew A. Bezdek, Brian P. Abelson, John S. Johnson, Eric H. Schumacher, Lucas C. Parra

Publications and Research

Naturalistic stimuli evoke highly reliable brain activity across viewers. Here we record neural activity from a group of naive individuals while viewing popular, previously-broadcast television content for which the broad audience response is characterized by social media activity and audience ratings. We find that the level of inter-subject correlation in the evoked encephalographic responses predicts the expressions of interest and preference among thousands. Surprisingly, ratings of the larger audience are predicted with greater accuracy than those of the individuals from whom the neural data is obtained. An additional functional magnetic resonance imaging study employing a separate sample of subjects shows …

Processing Government Data: Zip Codes, Python, And Openrefine, Frank Donnelly

Publications and Research

While there is a vast amount of useful US government data on the web, some of it is in a raw state that is not readily accessible to the average user. Data librarians can improve accessibility and usability for their patrons by processing data to create subsets of local interest and by appending geographic identifiers to help users select and aggregate data. This case study illustrates how census geography crosswalks, Python, and OpenRefine were used to create spreadsheets of non-profit organizations in New York City from the IRS Tax-Exempt Organization Masterfile. This paper illustrates the utility of Python for data …

Searching For Superspreaders Of Information In Real-World Social Media, Sen Pei, Lev Muchnik, José S. Andrade, Jr., Zhiming Zheng, Hernán A. Makse

Publications and Research

A number of predictors have been suggested to detect the most influential spreaders of information in online social media across various domains such as Twitter or Facebook. In particular, degree, PageRank, k-core and other centralities have been adopted to rank the spreading capability of users in information dissemination media. So far, validation of the proposed predictors has been done by simulating the spreading dynamics rather than following real information flow in social networks. Consequently, only model-dependent contradictory results have been achieved so far for the best predictor. Here, we address this issue directly. We search for influential spreaders by following …

An Examination Of Embedded Librarian Ideas And Practices: A Critical Bibliography., Carl R. Andrews

The Adverse Impact Of Racial Microaggressions On College Students' Self-Esteem, Kevin L. Nadal, Yinglee Wong, Katie E. Griffin, Kristin Davidoff, Julie Sriken

Publications and Research

Racial microaggressions are subtle (often unintentional or unconscious) forms of racial discrimination that negatively affect victims’ mental health. Utilizing an undergraduate student sample (N = 225), the current study examined the relationship between racial microaggressions and self-esteem. Results indicate that racial microaggressions negatively predict a lower selfesteem, and that microaggressions that occur in educational and workplace environments are particularly harmful to self-esteem. Finally, findings reveal that individuals of various racial and ethnic minority groups experience racial microaggressions differently. Implications for student development and recommendations for further research involving racial microaggressions and college students are discussed.

Hispanic Residential Ethnic Density And Depression In Post-Acute Coronary Syndrome Patients: Re-Thinking The Role Of Social Support, Ellen-Ge Denton, Jonathan A. Shaffer, Carmela Alcantra, Lynn Clemow, Elizabeth Denton

Publications and Research

Background: The ethnic density hypothesis suggests that ethnic density confers greater social support and consequently protects against depressive symptoms in ethnic minority individuals. However, the potential benefits of ethnic density have not been examined in individuals who are facing a specific and salient life stressor.

Aims: We examined the degree to which the effects of Hispanic ethnic density on depressive symptoms are explained by socioeconomic resources and social support.

Methods: Patients with acute coronary syndrome (ACS, N = 472) completed the Beck Depression Inventory (BDI) and measures of demographics, ACS clinical factors and perceived social support. Neighborhood characteristics, including median …

Alcohol Drinking Patterns And Differences In Alcohol-Related Harm: A Population-Based Study Of The United States, D. Antai, G. B. Lopez, J. Antai, D. S. Anthony

Publications and Research

Alcohol use and associated alcohol-related harm (ARH) are a prevalent and important public health problem, with alcohol representing about 4% of the global burden of disease. A discussion of ARH secondary to alcohol consumption necessitates a consideration of the amount of alcohol consumed and the drinking pattern. This study examined the association between alcohol drinking patterns and self-reported ARH. Pearson chi-square test (χ2) and logistic regression analyses were used on data from the National Comorbidity Survey Replication (NCS-R). The NCS-R is a cross-sectional nationally representative sample. Data was obtained by face-to-face interviews from 9282 adults aged ≥18 years in the …

Impedimetric Detection Of Mutant P53 Biomarker-Driven Metastatic Breast Cancers Under Hyposmotic Pressure, Menglu Shi, Nataly Shtraizent, Alla Polotskaia, Jill Bargonetti, Hiroshi Matsui

Publications and Research

In cancer cells, the oncogenic mutant p53 (mtp53) protein is present at high levels and gain-of-function (GOF) activities with more expression of mtp53 proteins contribute to tumor growth and metastasis. Robust analytical approaches that probe the degree of metastasis of cancer cells in connection with the mtp53 activity will be extremely useful not only for establishing a better cancer prognosis but also understanding the fundamental mechanism of mtp53 oncogenic action. Here we assessed the influence of mtp53 in breast cancers to the mechanical property of breast cancer cells. Recently, ovarian and kidney cancer cell lines have been shown to have …

Practicing Patienthood Online: Social Media, Chronic Illness, And Lay Expertise, Collette Sosnowy

Publications and Research

The use of digital technologies and social media by people with serious illness to find, share, and create health information is much celebrated but rarely critiqued. Proponents laud “Health 2.0” as transforming health care practice and empowering patients. Critics, however, argue that a discourse of developing lay expertise online masks the disciplinary practices of the neoliberal state’s emphasis on individual responsibility. Notably, the perspectives of people who are engaging with social media related to their health and illness are under-represented in this debate. This research examines the experiences and perspectives of women who blog about their lives with Multiple Sclerosis …

Teaching Writing In The Context Of A National Digital Literacy Narrative, Kelly S. Bradbury

Publications and Research

Despite commitments by composition studies and English education to using technology in the writing classroom and to developing teachers’ “critical technological literacy” (Selfe, 1999), not much has been written about how graduate programs can help secondary English teachers develop their own critical perspective on digital literacy and on teaching with technology. Recognizing this gap in scholarship, I created a series of assignments (The National Digital Literacy Narrative Project) to engage aspiring secondary English teachers in critical considerations of how public rhetoric about technology and literacy complicates composition studies scholarship and the contexts in which they will teach.

Bxpc3 Pancreatic Cancer Cells Express A Truncated Smad4 Protein Upon Pi3k And Mtor Inhibition, Onica Legendre, Ayisha Sookdeo, David A. Foster

Publications and Research

Smad4 is a critical regulator of transforming growth factor (TGF)-β signaling and is defective in numerous human cancers. In total, 30% of pancreatic cancers harbor a homozygous deletion of Smad4. The human pancreatic cancer cell line, BxPC3, has been reported to be Smad4-null due to a homozygous deletion and has been widely used as a Smad4-null model. The present study reports that Smad4 DNA is present in BxPC3 cells, and under conditions of suppressed mammalian target of rapamycin complex 1 (mTORC1) and phosphatidylinositol-3-kinase, a truncated Smad4 protein is expressed. While a high level of Smad4 protein can be expressed in …

Skin Cancer Prevention Coverage In Popular Us Women’S Health And Fitness Magazines: An Analysis Of Advertisements And Articles, Corey Hannah Basch, Danna Ethan, Grace Clarke Hillyer, Alyssa Berdnik

Publications and Research

The desire to be tan is a phenomenon that public health researchers have investigated, as exposure to UV radiation increases the chances of developing skin cancer. Media messages in women’s magazines have been shown to contribute to this problem. Much less is known about the prevalence of skin cancer prevention messages in these magazines. This study's aim was to identify the number and type of articles and advertised products devoted to skin health (sun protection and skin cancer prevention in particular) within five popular U.S. greater than women’s health and fitness magazines. We analyzed articles and advertisements over seven months …
