Finding The Right Fit: Assessing The Impact Of Traditional V. Large Lecture/Small Lab Course Formats On A General Education Course, Susan M. Wildermuth, Tammy French, Edward Fredrick

International Journal for the Scholarship of Teaching & Learning

This study explores alternative approaches for teaching general education courses burdened with serving extremely large enrollments. It compares the effectiveness of a self-contained course in which each course section is taught by one instructor to a large lecture/small lab format in which all course enrollees attend one large lecture section and then are divided into several small lab sections for more intensive training experiences. The study uses the Introduction to Human Communication course at the authors’ university. Two hundred and seventy-five students enrolled in nine large lecture/small lab sections of the course and two hundred and fifteen students enrolled in …

Embodied Conflict Resolution: Resurrecting Roleplay-Based Curricula Through Dance, Nadja Alexander, Michelle Lebaron

All Faculty Publications

Moving on from the authors’ seminal 2009 critique of the overuse of role-plays in negotiation teaching, "Death of the Role-Play" (chapter 13 in Rethinking Negotiation Teaching), Alexander and LeBaron have taken the rapidly increasing enthusiasm for experiential learning in a new direction: multiple intelligences. Their particular interest is in a use of experiential learning that focuses on kinesthetic intelligence, employing actual physical movement, particularly dance, to unlock creativity in other mental domains, as well as to encourage authentic participation by people whose skills are not primarily verbal or mathematical. Those who may be inclined to be skeptical should note that …

The U.S. Department Of Agriculture As A Public Health Agency, Lindsay Wiley

Scholarly Articles in Law Reviews & Journals

Introduction: The "war on obesity" is now well into its second decade.' What began as an effort to encourage medical doctors to screen and treat patients whose weight put them at risk for health problems has transformed into a much broader public health campaign to address the root causes of obesity. A growing number of state, territorial and local health departments are currently exploring new ways to promote healthy eating and physical activity. At the federal level, the U.S. Centers for Disease Control and Prevention (CDC) has made "nutrition, physical activity and obesity" a top priority.

Pronounced Genetic Structure In A Highly Mobile Coral Reef Fish, Caesio Cuning, In The Coral Triangle, Amanda S. Ackiss, Shinta Pardede, Eric D. Crandall, Ambariyanto, Ma. Carmen A. Ablan-Lagman, November Romena, Paul H. Barber, Kent E. Carpenter

School of Natural Sciences Faculty Publications and Presentations

The redbelly yellowtail fusilier, Caesio cuning, has a tropical Indo-West Pacific range that straddles the Coral Triangle, a region of dynamic geological history and the highest marine biodiversity on the planet. Previous genetic studies in the Coral Triangle indicate the presence of regional limits to connectivity across this region. However, these have focused almost exclusively on benthic reef dwelling species. Schooling, reef-associated fusiliers (Perciformes: Caesionidae) account for a sizable portion of the annual reef catch in the Coral Triangle, yet to date, there have been no in depth studies on the population structure of fusiliers or other mid-water, reef-associated …

Visual Analysis Of E-Textbooks For Senior High School In Indonesia, Ouda Ena

Dissertations

The purpose of the study was to evaluate the visual images used as illustrations in the English electronic textbooks for grades ten, eleven, and twelve in Indonesia. Qualitative visual content analysis was employed as the methodology of the research. The analysis focused on whether these e-textbooks accommodated the religious, gender, ethnic, and socioeconomic diversity of the students. These four aspects of cultural diversity that influenced students learning in Indonesian contexts were crucial to examine because the students were so diverse as results of the geographical conditions and historical background of Indonesia. Eight English e-textbooks were examined. First, the result showed …

Effects Of Electrical Stimulation And Testosterone In Translational Models Of Peripheral Nerve Injury, Gina Monaco

Dissertations

As functional recovery following peripheral nerve injury is dependent upon successful regeneration and target reconnection, combinatorial treatments that enhance different regeneration events may be required for recovery from severe injuries. The neurotherapeutic effects of electrical stimulation (ES) and gonadal steroids have been demonstrated independently and in combination in extratemporal and intratemporal facial nerve injuries. The goals of the first aim were to develop a reliable intracranial facial nerve crush model and to investigate the therapeutic potential of combining ES with testosterone propionate (TP) in this most proximal injury model. Adult male rats were divided into intracranial sham-operated, intracranial crush, and …

The research question was explored through fourteen hypotheses.

A mixed method approach was employed. For the first phase, 54 first-generation Asian Indians were recruited from four sites using a purposive convenience sampling method, the SAFE-R standardized questionnaire was used to measure acculturative stress, the COPE scale to measure coping strategies, and a culturally grounded Socio-Demographic Information …

A Study Of The Therapeutic Potential Of Af4 Mimetic Peptides, Nisha N. Barretto

Dissertations

Mixed lineage leukemias (MLL) are a group of acute and aggressive leukemias. They account for over 70% of infant leukemias, and 10% of acute adult leukemias. Pediatric ALL and therapy related MLL leukemias carry poor prognosis in spite of several advancement in the field of leukemia research. Therefore, new therapies for MLL leukemias are needed.

Majority of MLL leukemias arise due to the balanced translocations of the MLL gene. As a result of these translocations, chimeric MLL fusion proteins are expressed. The most frequently occurring MLL fusion proteins are known to aberrantly recruit the super elongation complex (SEC) resulting in …

Biophysical Characterization Of Tryptophan Locales, Mg²+ Binding And Protein Folding In Gα Subunits, Matthew Najor

Dissertations

The objective of this study is to understand the structure of guanine nucleotide - binding (G) proteins using a variety of spectroscopic tools. G proteins are membrane-bound proteins consisting of α, β, and γ subunits required for the transduction of extracellular signals to various intracellular effectors. Activation of G protein coupled receptors by neurotransmitters or hormones result in a conformational change of a G protein that is triggered by the exchange of guanosine 5'- diphosphate (GDP) bound to the  subunit for guanosine 5'- triphosphate (GTP) and concomitant dissociation of the  dimer.

Wild type (WT) Giα1 has three tryptophan …

Particulates Initiate Immune Response Via Inducing Oxidative Stress-Mediated Nlrp3 Inflammasome Activation, Zhenyu Zhong

Dissertations

Liposomes are lipid particles formed by self-aggregated phospholipids. They are clinically used both as delivery vectors and immune adjuvants to treat many human infectious and cancerous diseases. However, how liposomes interact with host immune system remains poorly understood. Particularly, little is known about whether an innate immune receptor exists to sense liposomes. I hypothesize that liposomes activate NLRP3 inflammasome in macrophages, which results in the release of interleukin 1β (IL-1β), a proinflammatory cytokine that plays a key role in innate and adaptive immune responses.

To test my hypothesis, I determined the ability of inducing IL-1β secretion from macrophages by differentially …

Menthol Binding And Inhibition Of A7-Nicotinic Acetylcholine Receptors, Abrar Ashoor, Jacob C. Nordman, Daniel Veltri, Keun-Hang Susan Yang, Lina T. Al Kury, Yaroslav M. Shuba, Mohamed Magoub, Frank Christopher Howarth, Bassem Sadek, Amarda Shehu, Nadine Kabbani, Murat Oz

Mathematics, Physics, and Computer Science Faculty Articles and Research

Menthol is a common compound in pharmaceutical and commercial products and a popular additive to cigarettes. The molecular targets of menthol remain poorly defined. In this study we show an effect of menthol on the α7 subunit of the nicotinic acetylcholine (nACh) receptor function. Using a two-electrode voltage-clamp technique, menthol was found to reversibly inhibit α7-nACh receptors heterologously expressed in Xenopus oocytes. Inhibition by menthol was not dependent on the membrane potential and did not involve endogenous Ca2+-dependent Cl− channels, since menthol inhibition remained unchanged by intracellular injection of the Ca2+ chelator BAPTA and perfusion with Ca2+-free bathing solution containing …

Differential Modulation Of Functional Dynamics And Allosteric Interactions In The Hsp90-Cochaperone Complexes With P23 And Aha1: A Computational Study, Kristin Blacklock, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Allosteric interactions of the molecular chaperone Hsp90 with a large cohort of cochaperones and client proteins allow for molecular communication and event coupling in signal transduction networks. The integration of cochaperones into the Hsp90 system is driven by the regulatory mechanisms that modulate the progression of the ATPase cycle and control the recruitment of the Hsp90 clientele. In this work, we report the results of computational modeling of allosteric regulation in the Hsp90 complexes with the cochaperones p23 and Aha1. By integrating protein docking, biophysical simulations, modeling of allosteric communications, protein structure network analysis and the energy landscape theory we …

Injunctive Peer Misperceptions And The Mediation Of Self-Approval On Risk For Driving After Drinking Among College Students, Shannon R. Kenney, Joseph W. Labrie, Andrew Lac

Heads Up!

Of the alcohol-related risks faced by college students, it is arguable that none presents a greater public health hazard than driving after drinking (DAD). The present study examined the extent to which students’ injunctive misperceptions toward DAD predicted the likelihood to engage in DAD and how this relation was mediated by self-approval of DAD. Participants were 2,848 college students (59.1% female, 64.6% Caucasian) from two U.S. West Coast universities who completed confidential web-based surveys assessing DAD beliefs and behaviors. Results revealed that respondents tended to overestimate their peers’ approval toward DAD. Moreover, the subgroups likely to engage in DAD—men, 21+ …

Metals And Bacteria Partitioning To Various Size Particles In Ballona Creek Storm Water Runoff, J. S. Brown, E. D. Stein, D. Ackerman, John H. Dorsey, J. Lyon, P. M. Carter

Center for Urban Resilience Scholarship

Many storm water best management practice (BMP) devices function primarily by capturing particulate matter to take advantage of the well‐documented association between storm water particles and pollutants. The hydrodynamic separation or settling methods used by most BMP devices are most effective at capturing medium to large particles; however, these may not be the most predominant particles associated with urban runoff. The present study examined particle size distribution in storm water runoff from an urban watershed in southern California and investigated the pollutant–particle associations of metals (Cu, Pb, Ni, and Zn) and bacteria (enterococci and Escherichia coli). During small storm …

The Next Generation Of Scientists: Examining The Experiences Of Graduate Students In Network-Level Social-Ecological Science, Michele Romolini, S. Record, R. Garvoille, Y. Marusenko, R. S. Geiger

Center for Urban Resilience Scholarship

By integrating the research and resources of hundreds of scientists from dozens of institutions, network-level science is fast becoming one scientific model of choice to address complex problems. In the pursuit to confront pressing environmental issues such as climate change, many scientists, practitioners, policy makers, and institutions are promoting network-level research that integrates the social and ecological sciences. To understand how this scientific trend is unfolding among rising scientists, we examined how graduate students experienced one such emergent social-ecological research initiative, Integrated Science for Society and Environment, within the large-scale, geographically distributed Long Term Ecological Research (LTER) Network. Through workshops, …

Development Of Alternative Host Models To Assess Virulence Potential Of Vibrio Parahaemolyticus, Jeffrey Sun

Master's Theses and Capstones

V. parahaemolyticus infection from ingesting shellfish is a global problem and incidence rates are on the rise in the U.S. Current detection methods are ineffective due to the lack of definite pathogenic marker thus studies to elucidate virulence mechanism are crucial and impeded by the lack of an efficient high-throughput model that emulate disease. Of multiple alternative models investigates, only C. elegans was able to discern different virulence potential among V. parahaemolyticus strains. In addition, the pandemic strain had greater colonization ability when in direct competition with the pre-pandemic strain in C.elegans intestine. A transposon insertion mutant library was generated …

Population Ecology Of American Marten In New Hampshire: Impact Of Wind Farm Development In High Elevation Habitat, Alexej Peder Kelly Siren

Master's Theses and Capstones

This study examined marten ecology relative to wind farm development using radio-marked marten, camera trapping, and snow track surveys to meet study objectives. The local population was mostly breeding adults and was considered near carrying capacity. Mortality (predation) was biased towards females and young. Seasonal home ranges were small overall, and largest during summer and when marten used more regenerating and softwood forest. Selection at the landscape scale was more pronounced than at the stand scale; regenerating forest was selected against year-round. Stand selection for mature mixed-wood and softwood occurred in winter. Disturbance from wind farm construction resulted in less …

Hiv-1 Frameshift Efficiency Is Primarily Determined By The Stability Of Base Pairs Positioned At The Mrna Entrance Channel Of The Ribosome, Kathryn Mouzakis

Chemistry and Biochemistry Faculty Works

The human immunodeficiency virus (HIV) requires a programmed -1 ribosomal frameshift for Pol gene expression. The HIV frameshift site consists of a heptanucleotide slippery sequence (UUUUUUA) followed by a spacer region and a downstream RNA stem-loop structure. Here we investigate the role of the RNA structure in promoting the -1 frameshift. The stem-loop was systematically altered to decouple the contributions of local and overall thermodynamic stability towards frameshift efficiency. No correlation between overall stability and frameshift efficiency is observed. In contrast, there is a strong correlation between frameshift efficiency and the local thermodynamic stability of the first 3-4 bp in …

Torsion In One-Term Distributive Homology, Alissa S. Crans, Józef H. Przytycki, Krzysztof K. Putyra

Mathematics, Statistics and Data Science Faculty Works

The one-term distributive homology was introduced by J.H.Przytycki as an atomic replacement of rack and quandle homology, which was first introduced and developed by R.Fenn, C.Rourke and B.Sanderson, and J.S.Carter, S.Kamada and M.Saito. This homology was initially suspected to be torsion-free, but we show in this paper that the one-term homology of a finite spindle can have torsion. We carefully analyze spindles of block decomposition of type (n,1) and introduce various techniques to compute their homology precisely. In addition, we show that any finite group can appear as the torsion subgroup of the first homology of some finite spindle. Finally, …

A Method Based On Total Variation For Network Modularity Optimization Using The Mbo Scheme, Huiyi Hu, Thomas Laurent, Mason A. Porter, Andrea L. Bertozzi

Mathematics, Statistics and Data Science Faculty Works

The study of network structure is pervasive in sociology, biology, computer science, and many other disciplines. One of the most important areas of network science is the algorithmic detection of cohesive groups of nodes called “communities.” One popular approach to finding communities is to maximize a quality function known as modularity to achieve some sort of optimal clustering of nodes. In this paper, we interpret the modularity function from a novel perspective: we reformulate modularity optimization as a minimization problem of an energy functional that consists of a total variation term and an $\ell_2$ balance term. By employing numerical techniques …

An Examination Of Opuntia Littoralis Fruit Volume, Sugar Concentration, Number Of Seeds And Average Seed Mass In Relation To Fitness, Victor D. Carmona, Kathleen Foster, Carolyne Hoey

Biology Faculty Works

Organisms cannot maximize all life functions and therefore must allocate resources to maximize reproductive fitness such that they produce the highest number of surviving offspring. The object of the experiment was to evaluate variation of fruit morphology to determine how Opuntia littoralis optimizes reproductive investment. The experiment focused on fruit volume, sugar concentration, number of seeds and average seed mass on two different aspects (polar-facing and equatorial-facing slopes) in Temescal Canyon Gateway Park, Pacific Palisades, California. The results revealed fruit volume was positively correlated with number of seeds, sugar concentration was positively correlated with number of seeds, and average seed …

A Preliminary Study Of Ricinus Communis Survivorship At Ballona Wetlands And Temescal Canyon, Los Angeles, California, Victor D. Carmona-Galindo, Daryle Hinton-Hardin, Jodi Kagihara, Mary Rose Pascua

Biology Faculty Works

Invasive plants such as Castor bean (Ricinus communis) are known to threaten ecosystems due to their competition for resources. The Ballona Wetlands and Temescal Canyon managers employ different techniques to manage the spread of R. communis, potentially resulting in differences in plant survivorship. To investigate this possibility, height of the stems of individual R. communis plants at each site were recorded in order to assign them to cohort groups. Based on the hypothesis predicted that R. communis would have a similar cohort structure at both sites but would exhibit higher survivorship at Temescal Canyon, where R. communis …
