Relapse Prevention/Substance Use Disorder Group
Danilo Mullins
Social Work
Graduate Student
College of Professional Studies
This project concists of my participation as a co-facilitator in a substance abuse relapse prevention group through the Redwood Community Action Agency (RCAA) located at Waterfront Recovery Services in Eureka. This group meets once a week with participants who are in the early stages of recovery and who are ready to learn new coping skills that will enhance the rate of success and minimize relapse incidents. Evidence-based practice methods as they pertain to the five models of group therapy used in substance abuse treatment is being utilized in addition to traditional cultural elements congruent with the Native American worldview.
Watershed Base Plane

Surveying Campbell creek watershed, located in north eastern Humboldt county on the edge of the Hoopa Indian Reservation, implementing mitigation plans for conservation and restoration. There are many environmental impacts that are hazardest to the water runoffs and aquifers such as legal/ illegal cannibus grow, illegal solid waste dumping, and sedimentation from old logging roads. Building maps would provide baseline information for measuring activity that can be harmful to the ecosystem that provides an abundance of resources for a complex bio-diversity and cultural resources for the Hupa Tribe.
University Singers

College of Arts, Humanities & Social Sciences
HSU's choirs have found ways to make music together despite the huge obstacle of not being able to rehearse together as we normally do. We have been primarily working on "virtual choir" projects and performances. For these projects, we rehearsed together online and then the students each recorded their part for each piece we worked on individually. The individual recordings were then compiled to create the performance videos shown here. These videos are from Fall 2020: University Singers performs "Safe with Me," a new and poignant piece by Bryan Sharpe, as well as a fun arrangement of "Feeling Good," the iconic tune made famous by Nina Simone.

This study examines the land-use changes along the south-east coast of Sri Lanka before and after the 2004 Tsunami to spot vulnerable areas for future monitoring efforts. A time-series vegetation change: (i) immediately after Tsunami between 2004-2005, (ii) pre-Tsunami & long-term between 2004 -2016 and (iii) post-Tsunami & long-term between 2005-2016 were mapped using Landsat TM images. The resulting series of multiple change detection models became a series of maps displaying a considerable disturbance of vegetation patterns and agricultural activity at the coastal and inland areas.
Effects of Ramorum Leaf Blight on Tanoak and California Bay Foliage

Redwood National Park, CA has recently been infected with Phytophthora ramorum, the pathogen that causes sudden oak death and ramorum leaf blight. Two common understory hardwoods, tanoak and California bay, are commonly infected by ramorum leaf blight. Foliage samples were collected from Tall Trees Grove and, photosynthetic capacity, stomatal conductance, and water potential readings were taken. Ramorum leaf blight decreased the photosynthetic capacity in both of the study species without affecting water use efficiency. The decline in photosynthesis leaves plants vulnerable, increasing the chances of further infection from separate pathogens.

The CB2 G-protein coupled receptors (GPCR) is found in the brainstem & hippocampus and is devoid of psychotropic effects but is less studied than the CB1 receptor. CB2 is inducible in CNS microglia following inflammation or injury, indicating a role in pain response. Here we sought to analyze CB2 using ChimeraX structures and overcome GPCR protein insolubility in extraction. The pET28a-CNR2, plasmid created and transformed into E.coli pLysS, was confirmed by restriction digest. Purification of CB2 micelles was achieved by affinity chromatography with detergent (43 kD). We aim to utilize nanodiscs to stabilize CB2, allowing studies of the molecular underpinnings informing treatment options.

Trace metal bioaccumulation negatively impacts marine ecosystem health and increases the risk of human exposure to contaminants. Pollution trends can be investigated by measuring trace metal bioaccumulation in algae, but little is known about which algal groups are the most reliable bioindicators. The objectives of this study were to use dry ashing, wet digestive, and spectroscopic techniques to determine the concentrations Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn across major macroalgae groups in Humboldt Bay, and evaluate bioindicator ability using BSAF values. Our results indicate that Chlorophyta and Rhodophyta are the most sensitive and suitable bioindicators for trace metal pollution.
Colorectal Cancer Disparities and Physical Activity Distribution Among Hispanics and Non-Hispanic Whites in New Mexico
Nathaniel McGuigan
University of New Mexico-Epidemiology and Biostatistics Department
Undergraduate Student
College of Natural Resources & Sciences
We studied changes in physical activity among Hispanic and Non-Hispanic Whites (NHW) to examine the difference in colorectal cancer (CRC) related risk factors between these 2 groups across time.
The UNM ColorectalDisease Prevention Study (M. Gonzales PI) surveyed the intensity of work and leisure physical activity at age 18, 30, 50 and/or year before diagnosis among 176 Hispanic and NHW CRC patients including additional risk factors which are known to differ between Hispanics and NHWs in New Mexico (Gonzales 2012).
Due to racial ethnic differences in CRC related risk factors, the need to raise awareness about CRC prevention is essential for the Hispanic communities in New Mexico.
Theatrical Folkloric Dance in Egypt

College of Arts, Humanities & Social Sciences
This poster showcases theatrical folkloric dance styles and companies representing diverse regions in Egypt. Dance, music and cultural arts began serving as a source of nationalistic pride in the years following Egypt's independence in the 1950's. This was the first time an appreciation of dance and dancers as folk artists was included in such a prominent role. Based on research and recent travels to explore folkloric dance in Egypt last year, this poster presents Maleya Leff, Fellahin, Raqs Sharqi, Tahtib, and Nubian dance forms. These vibrant regional dances have been developed and celebrated since the work of Mahmoud Reda's Reda Troupe in the 1960's and continues today.
Sequoia Park Zoo Youth Assistant Keepers
Savanna Schaffer

College of Arts, Humanities & Social Sciences
I have partnered with the Sequoia Park Zoo to revise their Youth Assistant Keeper Program to create a sustainable, impactful program that can be implemented with the use of a binder. Local, 11-15 year-olds will be guided through various aspects of zoos and animal husbandry while being asked to observe, critique, and explore the work of the Zoo and related work for best practices in animal care, equity, and accessibility. This unique opportunity for personal and academic development encourages autonomy and ownership over individual work, promotes leadership and diversity, cultivates a cooperative, team-centered environment, and inspires connection with and conservation of the natural world.
