Impact Of Open Educational Resources (Oer) On Student Academic Performance And Retention Rates In Undergraduate Engineering Departments, Yonchao Zhao, Ashwin Satyanarayana, Cailean Cooney

Publications and Research

To students and families already struggling to afford college tuition and fees, spending an additional $1,240 per year on books and supplies can be a breaking point. This cost constitutes as much as 39% of tuition and fees at a community college and 14% of tuition and fees at a four- year public institution (data obtained from the 2019-20 College Board survey for full-time undergraduate students). Moreover, due to the coronavirus pandemic, the demand for digital textbooks is surging and the problem is compounded by the fact that without on-campus resources, including library reserve textbook collections, students are facing more …

A New Beginning: Early Refugee Integration In The United States, Van C. Tran, Francisco Lara-García

Publications and Research

The U.S. refugee population not only has grown dramatically, but the countries from which the refugees are fleeing have also diversified over the last decade. Focusing on five recent refugee groups—Bhutanese, Burmese, Iraqis, Somalis, and Cubans, we examine how premigration characteristics and postmigration integration policies shape early socioeconomic integration in the United States. Our analyses point to three findings. First, early socioeconomic outcomes show only modest differences across refugee groups, despite significant variation in premigration selectivity in human capital. Second, the two possible pathways toward integration are schooling and employment. Third, postmigration integration policies matter. Our findings highlight the role …

Polydopamine Antioxidant Hydrogels For Wound Healing Applications, Naphtali A. O'Connor, Abdulhaq Syed, Madeline Wong, Josiah Hicks, Greisly Nunez, Andrei Jitianu, Zach Siler, Marnie Peterson

Publications and Research

Antioxidants are known to improve the wound healing process and are researched as a therapeutic strategy to treat chronic wounds. Dopamine is a known neurotransmitter with antioxidant properties that can be polymerized to form polydopamine (PDA). Herein, polydopamine is demonstrated as an antioxidant biomaterial. In prior work, we developed methodology to prepare hydrogels by crosslinking polysaccharides with polyamines via epichlorohydrin and NaOH. Using this previously developed methodology, dextran hydrogels crosslinked with polydopamine were prepared. Darkening of the gels indicated the increasing incorporation of polydopamine within the hydrogels. In addition to basic pH, polydopamine can be formed by reaction with polyethylene …

Hypogean Communities As Cybernetic Systems: Implications For The Evolution Of Cave Biotas, Aldemaro Romero Jr.

Publications and Research

Ramón Margalef proposed in 1968 that ecosystems could be better understood if they were viewed as cybernetic systems. I tested this hypothesis in the case of hypogean ecosystems using available pieces of evidence. I looked on how information on feedbacks, stability, succession, organization, diversity, and energy flows in the hypogean environment fit the cybernetics hypothesis. The results were that there are convincing arguments that the application of the concept of cybernetics in biospeleology can be beneficial to broadening our understanding of cave biota in terms of their structure. I also make the case that this approach can provide more clarity …

Introduction: Allostatic load (AL) defines cardiometabolic, inflammatory, and neuroendocrine changes in the body in response to internal and external stressors. It is largely unknown whether gestational diabetes mellitus (GDM) alters maternal and fetal AL, which in turn affects GDM outcomes. Whether dietary intakes and quality can modify AL and thus influence GDM progression is also unknown.

Research: design and methods In this study, we recruited 35 GDM and 30 non-GDM women in gestational week 25–33. Fasting blood samples were collectedat enrollment, and cord venous blood samples were collected at delivery for the measurement of a series of AL biomarkers to …

Beyond The Capitalist Workplace: How The Production Of Surplus Across The Economy Keeps Producers Divided, Costas Panayotakis

Publications and Research

This article analyzes the public and household sectors of the economy as sites of surplus production within contemporary capitalist societies. It also shows how the coexistence of structurally distinct spheres of surplus production creates divisions among workers in the private, public, and household sectors of the economy, thus amplifying the racial, gender, and other divisions which have often in the past kept working people divided. Fueling these cross-sector divisions is the appearance that private-sector workers are paid for their labor rather than for their labor-power. Thus, this article also explores an implication of this appearance which Karl Marx, the thinker …

A Putative Chordate Luciferase From A Cosmopolitan Tunicate Indicates Convergent Bioluminescence Evolution Across Phyla, Michael Tessler, Jean P. Gaffney, Anderson G. Oliveira, Andrew Guarnaccia, Krista C. Dobi, Nehaben A. Gujarati, Moira Galbraith, Jeremy D. Mirza, John S. Sparks, Vincent A. Pieribone, Robert J. Wood, David F. Gruber

Publications and Research

Pyrosomes are tunicates in the phylum Chordata, which also contains vertebrates. Their gigantic blooms play important ecological and biogeochemical roles in oceans. Pyrosoma, meaning “firebody”, derives from their brilliant bioluminescence. The biochemistry of this light production is unknown, but has been hypothesized to be bacterial in origin. We found that mixing coelenterazine—a eukaryote-specific luciferin—with Pyrosoma atlanticum homogenate produced light. To identify the bioluminescent machinery, we sequenced P. atlanticum transcriptomes and found a sequence match to a cnidarian luciferase (RLuc). We expressed this novel luciferase (PyroLuc) and, combined with coelenterazine, it produced light. A similar gene was recently predicted from a …

“Helping Me Learn New Things Every Day”: The Power Of Community College Students’ Writing Across Genres, Tanzina Ahmed

Publications and Research

Although community colleges are important entry points into higher education for many American students, few studies have investigated how their students engage with different genres or develop genre knowledge. Even fewer have connected students’ genre knowledge to their academic performance. In the present article, 104 ethnically, culturally, and linguistically diverse students reported on classroom genre experiences and wrote stories about college across three narrative genres (Letters, Best Experience, Worst Experience). Findings suggest that students’ engagement with classroom genres in community college helped them develop rhetorical reading and writing skills. When students wrote about their college lives across narrative genres, they …

Discriminating Global Orientation Of Two Element Sets, Aytaç Karabay, Daniel D. Kurylo

Publications and Research

Perceived global organization of visual patterns is based upon the aggregate contribution of constituent components. Patterns constructed from multiple sources cooperate or compete for global organization. An investigation was made here of interactions between two interspersed element sets on global orientation. It was hypothesized that each set would operate as an integrated unit, and contribute independently to global orientation. Participants viewed a 10 x 10 array of Gabor patches, and indicated the predominant orientation of the array. In Experiment 1 all elements were rotated. Rotation up to 23° had little effect, whereas greater rotation produced a progressive shift on global …
