Non-Parental Family Members As Brokers Of Family Social Capital: Compensatory Time Use In India, Melissa Alcaraz, Ashley Larsen Gibby, Nancy Luke

Faculty Publications

Non-parental family members are understudied but important brokers of family social capital, especially in contexts without a nuclear-family norm. We used rich time diary data from a sample of 1568 South Indian adolescents to examine the relationships between any time spent with parents, parents’ residency status, and the time spent with non-parental family members. We found that adolescents with at least one non-resident parent spent significantly more time with siblings, on average, when compared to adolescents with resident parents. We further found that adolescents spent more time with siblings in educational activities, such as studying, when they had at least …

Transport Of N-Cd And Pre-Sorbed Pb In Saturated Porous Media, Salahaddin Kamrani, Vahab Amiri, Mosleh Kamrani, Mohammed Baalousha

Faculty Publications

Carbon dots (CDs) are a new type of nanomaterials of the carbon family with unique characteristics, such as their small size (e.g., <10 nm), high water solubility, low toxicity, and high metal affinity. Modification of CDs by Nitrogen functional groups (N-CDs) enhances their metal adsorption capacity. This study investigated the influences of pH (4, 6, and 9), ionic strength (1, 50, and 100 mM), and cation valency (Na⁺ and Ca²⁺) on the competitive adsorption of Pb to quartz and N-CD surfaces, the transport and retention of N-CDs in saturated porous media, and the capacity of N-CDs to mobilize pre-adsorbed Pb in quartz columns. Pb adsorption was higher on N-CDs than on quartz surfaces and decreased with increases in ionic strength (IS) and divalent cations (Ca²⁺) concentration. N-CD mobility in quartz columns was highest at pH of 9- and 1-mM monovalent cations …

A Decade Review Of Triphosgene And Its Applications In Organic Reactions, Moshood O. Ganiu, Binod Nepal, Joshua P. Van Houten, Rendy Kartika

Faculty Publications

© 2020 Elsevier Ltd This review article highlights selected advances in triphosgene-enabled organic synthetic reactions that were reported in the decade of 2010–2019. Triphosgene is a versatile reagent in organic synthesis. It serves as a convenient substitute for the toxic phosgene gas. Despite its first known preparation in the late 19th century, the upward surge in the development of organic reactions using triphosgene interestingly began only three decades ago. Despite the relatively short history, triphosgene has been proven to be very useful in facilitating the preparation of a vast scope of value-added compounds, such as organohalides, acid chlorides, isocyanates, carbonyl …

Whether you have finding aids to use as a base for your catalog record or you are working directly with the materials, guidelines for using DACS and RDA for manuscript …

Mapping Flat, Deep, And Slow: On The 'Spirit Of Place' In New Cinema History, Jeffrey Klenotic

Faculty Publications

This essay engages in a creative, heuristic, and reflexive consideration of the ‘localities’ of cinema audiences by exploring New Cinema History as a place. New Cinema History is conceptualised as a place continually produced in and through its interactions with the heterogeneous multiplicities of situated audiences and experiences of cinema that form the topoi of its landscape of inquiry. In reflecting on how this placialised landscape has been and might be represented, I argue that New Cinema History’s ‘spirit of place’ is most productive when rendered within a ‘splatial’ framework that draws upon practices of flat, deep, and slow mapping …

Two Kinds Of Polar Knowledge, Lawrence C. Hamilton

Faculty Publications

Outreach and communication with the public have substantial value in polar research, in which studies often find changes of global importance that are happening far out of sight from the majority of people living at lower latitudes. Seeking evidence on the effectiveness of outreach programs, the U.S. National Science Foundation sponsored large-scale survey assessments before and after the International Polar Year in 2007/2008. Polar-knowledge questions have subsequently been tested and refined through other nationwide and regional surveys. More than a decade of such work has established that basic but fairly specific knowledge questions, with all answer choices sounding plausible but …

Civilian Pepper Spray For Self Defense: Understanding User Perception And Impact Of Design On User Performance, David Strybel, Anil R. Kumar

Faculty Publications

Pepper spray is widely used in the US, and is marketed as an effective self-defense device. While pepper spray can be useful in deterring an attacker, many pepper spray owners do not have any experience using it. There is a dearth of published studies that focus on civilian pepper-spray use, not to mention first time pepper-spray users. A study to analyze pepper-spray designs with first-time users, to see how the design, specifically the safety mechanism, affects response time and overall performance would be helpful. The study was conducted in 2 parts – a survey to understand user perception, and a …

Guy, Ashley N. Payan, Fuqiang Ban, Artem Cherkasov, Marc B. Cox, Dong Liang, Huan Xie

Faculty Publications

Background: GMC1 (2-(1H-benzimidazol-2-ylsulfanyl)-N-[(Z)-(4-methoxyphenyl) methylideneamino] acetamide) effectively inhibits androgen receptor function by binding directly to FKBP52. This is a novel mechanism for the treatment of castration resistant prostate cancer (CRPC). Methods: an LC-MS/MS method was developed and validated to quantify GMC1 in plasma and urine from pharmacokinetics studies in rats. An ultra-high-performance liquid chromatography (UHPLC) system equipped with a Waters XTerra MS C18 column was used for chromatographic separation by gradient elution with 0.1% (v/v) formic acid in water and methanol. A Sciex 4000 QTRAP® mass spectrometer was used for analysis by multiple reaction monitoring (MRM) in positive mode; the specific …

Chain-Selective Isotopic Labeling Of The Heterodimeric Type Iii Secretion Chaperone, Scc4:Scc1, Reveals The Total Structural Rearrangement Of The Chlamydia Trachomatis Bi-Functional Protein, Scc4, Thilini O. Ukwaththage, Samantha M. Keane, Li Shen, Megan A. Macnaughtan

Faculty Publications

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Scc4 is an unusual bi-functional protein from Chlamydia trachomatis (CT) that functions as a type III secretion system (T3SS) chaperone and an RNA polymerase (RNAP)-binding protein. Both functions require interactions with protein partners during specific stages of the CT developmental cycle. As a T3SS chaperone, Scc4 binds Scc1 during the late stage of development to form a heterodimer complex, which chaperones the essential virulence effector, CopN. During the early-middle stage of development, Scc4 regulates T3SS gene expression by binding the σ66-containing RNAP holoenzyme. In order to study the structure and association …

Microbiological, Physicochemical, And Immunological Analysis Of A Commercial Cashew Nut-Based Yogurt, Christopher P. Mattison, Kayanush Aryana, Kristen Clermont, Eric Prestenburg, Steven W. Lloyd, Casey .. Grimm, Richard L. Wasserman

Faculty Publications

Nut-based milks and yogurts are gaining popularity, but may not offer the same benefits as dairy yogurts to consumers. Cashew nuts often cause severe allergic reactions, and cashew nut allergens are stable to several types of processing. To compare its characteristics to dairy yogurt and characterize the effects of fermentation on the Ana o 1-3 cashew nut allergens, a commercial yogurt made from cashew nuts (Cashewgurt) was evaluated for microbiological, physiochemical, and immunological properties. Average counts for lactobacilli and Streptococcus thermophilus were greater than 10 million colony forming units per milliliter, indicating the capacity to provide a health benefit. Cashewgurt …

Speciation-By-Depth On Coral Reefs: Sympatric Divergence With Gene Flow Or Cryptic Transient Isolation?, Carlos Prada, Michael E. Hellberg

Faculty Publications

The distributions of many sister species in the sea overlap geographically but are partitioned along depth gradients. The genetic changes leading to depth segregation may evolve in geographic isolation as a prerequisite to coexistence or may emerge during primary divergence leading to new species. These alternatives can now be distinguished via the power endowed by the thousands of scorable loci provided by second-generation sequence data. Here, we revisit the case of two depth-segregated, genetically isolated ecotypes of the nominal Caribbean candelabrum coral Eunicea flexuosa. Previous analyses based on a handful of markers could not distinguish between models of genetic exchange …

Mere Common Ownership And The Antitrust Laws, Thomas A. Lambert

Faculty Publications

"Common ownership," also called "horizontal shareholding," refers to a stock investor's ownership of minority stakes in multiple competing firms. Recent empirical studies have purported to show that institutional investors' common ownership reduces competition among commonly owned competitors. "Mere common ownership" is horizontal shareholding that is not accompanied by any sort of illicit agreement, such as a hub-and-spoke conspiracy, or the holding of a control-conferring stake. This Article considers the legality of mere common ownership under the U.S. antitrust laws. Prominent antitrust scholars and the leading treatise have concluded that mere common ownership that has the incidental effect of lessening market …

A Theory Of Multiformat Communication: Mechanisms, Dynamics, And Strategies, Jordan W. Moffett, Judith Anne Garretson Folse, Robert W. Palmatier

Faculty Publications

Extant communication theories predate the explosion of digital formats and technological advances such as virtual reality, which likely explains their predominant focus on traditional and format-level (e.g., face-to-face, email) rather than digital or characteristic-level (e.g., visual cues, synchronicity) design decisions. Firms thus lack insights into how to create and use emerging digital formats, individually or synergistically. To establish a holistic framework of bilateral multiformat communication for relationship marketing, this article reviews communication theory to establish a foundation for understanding multiformat communication and to identify any gaps (e.g., AI agents, simulated cues). The authors then review bilateral communication research in light …

Potential Link Between Compromised Air Quality And Transmission Of The Novel Corona Virus (Sars-Cov-2) In Affected Areas, M. G. Manoj, M. K. Satheesh Kumar, K. T. Valsaraj, C. Sivan, Soumya K. Vijayan

Faculty Publications

The emergence of a novel human corona virus disease (COVID-19) has been declared as a pandemic by the World Health Organization. One of the mechanisms of airborne transmission of the severe acute respiratory syndrome corona virus (SARS-CoV-2) amid humans is through direct ejection of droplets via sneezing, coughing and vocalizing. Nevertheless, there are ample evidences of the persistence of infectious viruses on inanimate surfaces for several hours to a few days. Through a critical review of the current literature and a preliminary analysis of the link between SARS-CoV-2 transmission and air pollution in the affected regions, we offer a perspective …

Towards A Scalable And Distributed Infrastructure For Deep Learning Applications, Bita Hasheminezhad, Shahrzad Shirzad, Nanmiao Wu, Patrick Diehl, Hannes Schulz, Hartmut Kaiser

Faculty Publications

Although recent scaling up approaches to train deep neural networks have proven to be effective, the computational intensity of large and complex models, as well as the availability of large-scale datasets require deep learning frameworks to utilize scaling out techniques. Parallelization approaches and distribution requirements are not considered in the primary designs of most available distributed deep learning frameworks and most of them still are not able to perform effective and efficient fine-grained inter-node communication. We present Phylanx that has the potential to alleviate these shortcomings. Phylanx presents a productivity-oriented frontend where user Python code is translated to a futurized …

Financial Socialization: A Decade In Review, Ashley B. Lebaron, Heather H. Kelly

Faculty Publications

The financial socialization individuals receive is associated not only with their future financial wellbeing but also relational, mental, and physical wellbeing. This paper is a review of the literature on financial socialization, especially papers published between 2010 and 2019 in the Journal of Family and Economic Issues. We first review family financial socialization theory and then review empirical documentation for the theory, organized by (a) family socialization processes (e.g., parent financial modeling, parent-child financial discussion, and experiential learning as three primary methods of financial socialization) and (b) financial socialization outcomes (e.g., financial attitudes, financial knowledge, financial behaviors, and financial wellbeing). …

Development Of Metallic Nuclear Material Purification Process Via Simultaneous Chlorination And Volatilization, Parker Okabe, Devin Rappleye, Matthew Newton, Michael F. Simpson

Faculty Publications

A purification process involving simultaneous chlorination and volatilization is reported using aluminum, iron, gallium, and uranium separation from cerium metal as the demonstration system. Anhydrous Cl₂ gas was reacted with the metal after it had been converted to small particles of hydride at temperatures ranging from 523 to 973 K. Each of the impurities should form chlorides with relatively high saturated vapor pressures. The objective of the process was to volatilize these chlorides after first achieving near-complete conversion of the metals to hydride and then chlorides. Complete conversion of hydrides to chlorides could not be achieved using …

Why Parents Say No To Having Their Children Vaccinated Against Measles: Social Determinants Of Parental Perceptions To Vaccine Hesitancy, M. Lelinneth B. Novilla, Michael C. Goates, Mallory Showalter, Lynneth Kirsten B. Novilla, Tyler Leffler, Russell B. Doria, Michael T. Dang, Katelyn Aldridge

Faculty Publications

Background: Although national and state immunization coverage rates are high, the resurgence of measles points to local pockets of under-vaccination that correspond with higher non-medical exemptions and lower parental confidence on vaccines. The reported geographic clustering of vaccine hesitancy, particularly against MMR, points to social drivers that shape parental perceptions and decisions on immunization.

Objectives. To analyze: (1) why parents delay or refuse vaccination, specifically MMR; (2) social context of vaccine hesitancy and perceived reliable sources of vaccine information between vaccine-hesitant and vaccine-compliant parents/guardians; (3) role of families in countering vaccine hesitancy; (4) strategies at the public health, primary care, …

Terminal Logic Behavior And Strategic Defection Of Governmental Officials During Presidential Transitions In Guatemala: Implications For The Sustainability Of Food And Nutrition Security Policy, Jessica L. Escobar-Alegria, Edward A. Frongillo Jr., Christine E. Blake

Faculty Publications

Background: Presidents with no possibility of re-election overvalue far-future rewards and succumb to terminal logic behavior (TLB), responding to end-of-tenure legacy concerns despite political context. Government authorities perceiving the outgoing government is losing power at the end of term behave under the logic of strategic defection (SD), dissociating from the outgoing government once it is perceived powerless. In countries where re-election is impossible and government turnover and inconstant political parties are concerns, governmental officials at all levels may show TLB and SD during transitions that affect policy sustainability. Objectives: This study aimed to understand the context during presidential transitions that …

Ten Years Of Marriage And Cohabitation Research In The Journal Of Family And Economic Issues, Jeffrey P. Dew

Faculty Publications

I reviewed the 36 marriage and cohabitation studies from the Journal of Family and Economic Issues articles published between 2010–2019. Nearly all of the studies used quantitative methods, and two-thirds of them used publicly available nationally-representative data. The studies fell into roughly five, unevenly sized groups: family structure, relationship quality, division of labor/employment, money management, and an “other” category. Suggestions for future research include applying some of the important questions within the articles to underrepresented groups, further examining the process of how finances and relationship quality interrelate and doing more applied and translational research.

“When Someone Sees Me, I Am Nothing Of The Norm”: Examining The Discursive Role Power Plays In Shaping Lgbtq+ Health Information Practices, Vanessa L. Kitzie, Travis L. Wagner, A. Nick Vera

Faculty Publications

This paper examines how discursive power shapes LGBTQ+ community health information practices. Informed by analysis of 10 information world maps drawn by SC LGBTQ+ community leaders, our findings indicate that while community can be a valuable construct to reject mainstream discourses of regulation and correction, it inevitably is fraught and not representative of all LGBTQ+ individuals. Findings can inform strategies for community leaders to facilitate more equitable information flow among members by identifying key structural elements impeding this flow at the community level.

The Protective Role Of Couple Communication In Moderating Negative Associations Between Financial Stress And Sexual Outcomes For Newlyweds, Jocelyn S. Wikle, Chelom E. Leavitt, Jeremy B. Yorgason, Jeffrey P. Dew, Heather M. Johnson

Faculty Publications

This study longitudinally examined the sexual costs of economic distress in newlywed couple relationships. Family stress theory posits an association between economic pressure and family relationships. The ability of financial strain to contaminate non-financial aspects of a marriage is troubling considering that many newlyweds report difficulty with financial adjustments after marriage. Positive communication may be a skill that enables young couples to alleviate economic pressure, and the study evaluated the moderating roles of financial communication, sexual communication, and relational communication. Utilizing an actor-partner interdependence moderation model, hypotheses were tested using dyadic data from 2044 couples from a nationally representative sample …
