The Anchor, Volume 131.14: January 24, 2018, Hope College

The Anchor: 2018

The Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor's history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). In recent years The Anchor moved to monthly print issues and a more frequently updated website. The Anchor is now published in print twice per academic semester. Occasionally, the volume and/or issue numbering is irregular.

Discounting And Digit Ratio: Low 2d:4d Predicts Patience For A Sample Of Females, Diego Aycinena, Lucas Rentschler

Economics and Finance Faculty Publications

Inter-temporal trade-offs are ubiquitous in human decision making. We study the relationship between preferences over such trade-offs and the ratio of the second digit to that of the forth (2D:4D), a marker for pre-natal exposure to sex hormones. Specifically, we study whether 2D:4D affects discounting. Our sample consists of 419 female participants of a Guatemalan conditional cash transfer program who take part in an experiment. Their choices in the convex time budget (CTB) experimental task allow us to make inferences regarding their patience (discounting), while controlling for present-biasedness and preference for smoothing consumption (utility curvature). We find that women with …

Evaluating The Impact Of An Exotic Plant Invasion On Rodent Community Richness And Abundance, Trinity N. Smith, Eric M. Gese, Bryan M. Kluever

Wildland Resources Faculty Publications

Cheatgrass (Bromus tectorum), Russian thistle (Salsola kali), and tall tumblemustard (Sisymbrium altissimum) are nonnative plants widely distributed throughout the desert and shrubsteppe communities of the western United States. The impact of these invaders on plant community structure, form, and function has been well documented, but investigations determining the impacts of this cumulative invasion on terrestrial vertebrates have not been undertaken. Our objective was to assess community-level rodent responses to changes in plant community features, with an emphasis on dominance of invasive plant species. We sampled rodent and plant communities in the Great Basin Desert …

Informing Efforts To Develop Nitroreductase For Amine Production, Anne-Frances Miller, Jonathan T. Park, Kyle L. Ferguson, Warintra Pitsawong, Andreas S. Bommarius

Chemistry Faculty Publications

Nitroreductases (NRs) hold promise for converting nitroaromatics to aromatic amines. Nitroaromatic reduction rate increases with Hammett substituent constant for NRs from two different subgroups, confirming substrate identity as a key determinant of reactivity. Amine yields were low, but compounds yielding amines tend to have a large π system and electron withdrawing substituents. Therefore, we also assessed the prospects of varying the enzyme. Several different subgroups of NRs include members able to produce aromatic amines. Comparison of four NR subgroups shows that they provide contrasting substrate binding cavities with distinct constraints on substrate position relative to the flavin. The unique architecture …

Experimental Evidence Of A Pathogen Invasion Threshold, Tad A. Dallas, Martin Krkošek, John M. Drake

Faculty Publications

© 2018 The Authors. Host density thresholds to pathogen invasion separate regions of parameter space corresponding to endemic and diseasefree states. The host density threshold is a central concept in theoretical epidemiology and a common target of human and wildlife disease control programmes, but there is mixed evidence supporting the existence of thresholds, especially in wildlife populations or for pathogens with complex transmission modes (e.g. environmental transmission). Here, we demonstrate the existence of a host density threshold for an environmentally transmitted pathogen by combining an epidemiological model with a microcosm experiment. Experimental epidemics consisted of replicate populations of naive crustacean …

Horizon Scanning: Survey And Research Priorities For Cultural, Historical, And Paleobiological Resources Of Santa Cruz Island, California, Torben C. Rick, Todd J. Braje, Jon M. Erlandson, Kristina M. Gill, Laura Kirn, Lynn Mclaren-Dewey

Western North American Naturalist

Santa Cruz Island contains a remarkable array of cultural and biological resources and a rich tradition of research across the social and biological sciences and humanities. Given dramatic changes in climate forecast in the coming decades of the Anthropocene, however, many questions remain about the sustainability and future of island ecosystems and cultural resources. Here, we focus on a new interdisciplinary initiative, Island Rediscovery (IR), that was the subject of 2 recent workshops. Drawing on a variety of disciplines and approaches, IR seeks to utilize research on Santa Cruz Island’s past and present to help better prepare for the future …

Temporal Changes In Phytoplankton Biomass And Cellular Properties; Implications For The Imo Ballast Water Convention, Mct Castro, M Veldhuis

School of Biological and Marine Sciences

In the Wadden Sea, the Netherlands, and at L4 in the English Channel, UK, the size class distribution of phytoplankton was investigated with respect to the size range >10–=50 µm identified by the IMO Ballast Water Convention. Size fractionation using 10 µm mesh filtration showed considerable size bias; 23.1% of >10 µm cells were still present in the <10 µm, but 21.8% of the smaller size cells were also retained on the mesh, resulting in an overestimated number of cells/mL by as much as a factor of 5.4. Flowcytometry measurements indicated that the phytoplankton in the size range 2–50 µm was dominated by the smaller size (<10 µm) at both sites. For the >10–=50 µm size, these were on average 3.6% and 2% in the Wadden Sea and at L4, respectively. In terms of chlorophyll biomass, they represented 28.7% and 12%, respectively. The filtration method resulted in much higher chlorophyll values for 10–50 µm size …

Fk506-Binding Protein 12.6/1b, A Negative Regulator Of [Ca2+], Rescues Memory And Restores Genomic Regulation In The Hippocampus Of Aging Rats, John C. Gant, Eric M. Blalock, Kuey-Chu Chen, Inga Kadish, Olivier Thibault, Nada M. Porter, Philip W. Landfield

Pharmacology and Nutritional Sciences Faculty Publications

Hippocampal overexpression of FK506-binding protein 12.6/1b (FKBP1b), a negative regulator of ryanodine receptor Ca²⁺ release, reverses aging-induced memory impairment and neuronal Ca²⁺ dysregulation. Here, we tested the hypothesis that FKBP1b also can protect downstream transcriptional networks from aging-induced dysregulation. We gave hippocampal microinjections of FKBP1b-expressing viral vector to male rats at either 13 months of age (long-term, LT) or 19 months of age (short-term, ST) and tested memory performance in the Morris water maze at 21 months of age. Aged rats treated ST or LT with FKBP1b substantially outperformed age-matched vector controls and performed similarly …

Treatment And Outcomes Of Non-Small-Cell Lung Cancer Patients With High Comorbidity, Jorge Rios, Rahul Gosain, Bernardo H. L. Goulart, Bin Huang, Margaret N. Oechsli, Jaclyn K. Mcdowell, Quan Chen, Thomas Tucker, Goetz H. Kloecker

Biostatistics Faculty Publications

Background: The life expectancy of untreated non-small-cell lung cancer (NSCLC) is dismal, while treatment for NSCLC improves survival. The presence of comorbidities is thought to play a significant role in the decision to treat or not treat a given patient. We aim to evaluate the association of comorbidities with the survival of patients treated for NSCLC.

Methods: We performed a retrospective study of patients aged ≥66 years with invasive NSCLC between the years 2007 and 2011 in the Surveillance, Epidemiology, and End Results Kentucky Cancer Registry. Comorbidity was measured using the Klabunde Comorbidity Index (KCI), and univariate and multivariate logistic …

Crayfish Harvesting Practices In The Southern Atchafalaya River Basin: Quantitative And Qualitative Assessment Of Harvester Techniques And Hydrologic Connectivity Influence On Harvesting Strategies, Ivan A. Vargas-Lopez

LSU Master's Theses

Fisheries produce important impacts around the world through the exploitation of a wide range of species. In Louisiana, crayfish is the most emblematic crustacean and supports a multi-million industry based on pond culture and harvest from natural habitats. Although the economic value (USD) of wild-harvested crayfish has decreased from 10% to 3% of total crayfish value from 2013 to 2015, wild harvested crayfish are highly desired by many consumers and have a strong socio-cultural importance in Louisiana and other Gulf of Mexico coastal regions. This project evaluated harvesting practices by: 1) field observation and mapping of harvest sites in southwestern …

Investigating Sociodemographic Disparities In Cancer Risk Using Web-Based Informatics, Hong-Jun Yoon, Georgia Tourassi

Journal of Human Performance in Extreme Environments

Cancer health disparities due to demographic and socioeconomic factors are an area of great interest in the epidemiological community. Adjusting for such factors is important when developing cancer risk models. However, for digital epidemiology studies relying on online sources such information is not readily available. This paper presents a novel method for extracting demographic and socioeconomic information from openly available online obituaries. The method relies on tailored language processing rules and a probabilistic scheme to map subjects’ occupation history to the occupation classification codes and related earnings provided by the U.S. Census Bureau. Using this information, a case-control study is …

Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña

Journal of Human Performance in Extreme Environments

Exposure to extreme environments is both mentally and physically taxing, leading to suboptimal performance and even life-threatening emergencies. Physiological and cognitive monitoring could provide the earliest indicator of performance decline and inform appropriate therapeutic intervention, yet little research has explored the relationship between these markers in strenuous settings. The Rim-to-Rim Wearables at the Canyon for Health (R2RWATCH) study is a research project at Sandia National Laboratories funded by the Defense Threat Reduction Agency to identify which physiological and cognitive phenomena collected by non-invasive wearable devices are the most related to performance in extreme environments. In a pilot study, data were …

Direct Detection Of Shigella In Stool Specimens By Use Of A Metagenomic Approach, Jie Liu, Mathieu Almeida, Furqan Kabir, Sadia Shakoor, Shahida Qureshi, Anita K. M. Zaidi, Shan Li, Boubou Tamboura, Samba O. Sow, Inacio Mandomando

Department of Paediatrics and Child Health

The underestimation of Shigella species as a cause of childhood diarrhea disease has become increasingly apparent with quantitative PCR (qPCR)-based diagnostic methods versus culture. We sought to confirm qPCR-based detection of Shigella via a metagenomics approach. Three groups of samples were selected from diarrheal cases from the Global Enteric Multicenter Study: nine Shigella culture-positive and qPCR-positive (culture⁺ qPCR⁺) samples, nine culture-negative but qPCR-positive (culture^- qPCR⁺) samples, and nine culture-negative and qPCR-negative (culture^- qPCR^-) samples. Fecal DNA was sequenced using paired-end Illumina HiSeq, whereby 3.26 × 10⁸ ± 5.6 × 10 …

Helicobacter Pylori Moderates The Association Between 5-Mthf Concentration And Cognitive Function In Older Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Objective: To explore potential interactions between folate-cycle factors and Helicobacter pylori seropositivity in the prediction of cognitive function. Methods We used data obtained from the 1999–2000 continuous National Health and Nutrition Examination Survey produced by the United States’ Centers for Disease Control and Prevention. Using Ordinary Least Squares regression, we tested for associations between multiple folate-cycle factors, Helicobacter pylori seropositivity, and cognitive function assessed by the digit symbol coding subtest of the Wechsler Adult Intelligence Scale-III. We then tested for interactions between each of the folate-cycle factors and Helicobacter pylori in the prediction of cognitive function.

Results: Although Helicobacter pylori …

Understanding Abrupt Climate Change Over The Last 100,000 Years, Jennifer Hertzberg

Sustainability Seminar Series

Unlike the relatively stable climate Earth has experienced throughout the Holocene, Earth's climate system underwent a series of abrupt oscillations and reorganizations during the last glacial period and termination.

The first part of this seminar will investigate the trigger for the atmospheric CO2 rise that occurred during the last deglaciation, beginning 17,500 years ago. I will show that abrupt changes in the Atlantic Meridional Overturning Circulation occurring synchronously with the initial CO2 rise may have altered the oceanic biological pump, allowing CO2 to accumulate in the surface ocean and atmosphere. Records of surface and intermediate water foraminiferal δ13C suggest that …

Backpacks: A Program For Improving Children’S Readiness To Learn And Family Food Security, Lauri Wright

Showcase of Faculty Scholarly & Creative Activity

An increasing gap has been seen between the government food assistance programs and need. One program filling the deficit is Feeding America’s BackPack Program. The Backpack provides nutritious food to children to eat on the weekends when they may not have access to an adequate amount of food. This study evaluated the impact of the program on children’s food security, readiness to learn, and behavioral and mental health. A mixed methodology was utilized. Results showed improved food security and increased readiness to learn among participants. BackPack may be an effective program for meeting the gap in food assistance.

Development And Sex Ratio Of Melittobia Australica And M. Digitata (Hymenoptera: Eulophidae) On Megachile Rotundata (Hymenoptera: Megachilidae) And Trypoxylon Politum (Hymenoptera: Sphecidae), Jorge M. Gonzalez, Robert W. Matthews

The Great Lakes Entomologist

Life history, development time, and sex ratio of Melittobia australica Girault and M. digitata Dahms on Megachile rotundata (Fabricius) and Trypoxylon politum Say are presented and compared with previous reports. Total development time and sex ratio differs slightly among the different hosts but falls within the expected range reported for different hosts and Melittobia species. The slightly longer development times and higher proportion of males recorded for both species on M. rotundata hosts probably reflects poorer host nutritional quality, relative to T. politum. We confirm that the one unusually extended development time reported by Schmieder for Melittobia chalybii Ashmead …

Ground Beetles (Coleoptera: Carabidae) Inhabiting Stands Of Reed Canary Grass Phalaris Arundinacea On Islands In The Lower Chippewa River, Wisconsin, Paula K. Kleintjes, Anita M. Christensen, William J. Barnes, Lori A. Lyons

The Great Lakes Entomologist

We used pitfall traps to assess ground beetle diversity (Coleoptera:Carabidae) on two islands in the lower Chippewa River, Eau Claire County, Wisconsin, with rapidly expanding populations of reed canary grass, Phalaris arundinaceae. We collected 233 individuals belonging to 17 species over four, 3-9 day sampling periods, May-August 1994. All species have been documented in Wisconsin and most are considered habitat generalists. Agonum fidele, A. extensicolle, Anisodactylus harrisii and Bembidion quadrimaculatum oppositum comprised 70% of all species collected. Seven species were common to both islands, with 13 species collected on Canarygrass Island and 11 species on Ski Jump Island. Carabid …
