The current study examined the association of stress, anxiety, hopelessness and social support in undergraduate Latino and White students. The sample included 250 Latino (women = 76%) and 296 White (women = 66%) participants, with more women in the Latino group (chi2 = 5.74, p < .05). For the total sample, a hierarchical linear regression with stress as the dependent variable, age and sex entered in block one and anxiety, social support, and hopelessness in block two, resulted in an R = .772 with block two variables accounting for 57% of the variance. Separate regression analyses for Latino and White students produced similar results, R = .75 and R = .80, respectively.
Structural Determination of the Olfactory Epithelium in Terrestrial Adult Rough-Skinned Newts (Taricha granulosa)
- Amber Van HeckeDepartment of Biological SciencesUndergraduate Student
Taricha granulosa (rough-skinned newt) uses olfaction for feeding, migration, and mate choice. In this study, we are examining the olfactory epithelium with scanning and transmission electron microscopy to determine whether variation in cellular morphology exists amongst seasonally terrestrial adults and aquatic larvae.
Student Legal Lounge
- Reza SadeghzadehCommunicationUndergraduate Student
- Kimo MartinPolitical ScienceUndergraduate Student
The Student Legal Lounge (SLL) is an on-campus resource created by students for students. SLL provides the pupils of HSU with legal information, which has been researched by students in many different legal fields; such as housing rights, immigration rights, constitutional rights, and etc. In addition, SLL has commenced an attorney referral program, so that our students have the adequate tools when they are faced with a serious legal quandary. Needless to say, not only is the SLL a great on-campus resource for HSU students, but it also provides an opportunity for involvement for those who are interest in legal work a chance to gain communication, research, organizational skills.
Student Perceptions of Diversity in University Curriculum: Informing Course Design
- Irene GonzalezPsychologyUndergraduate Student
- Mariah MartinezPsychologyUndergraduate Student
- Zachary OtteyPsychologyUndergraduate Student
- Carrie AignerPsychologyFaculty
When aspects of culture and diversity are integrated into courses, students can benefit in many ways including enhanced critical thinking and greater social agency, or one’s belief in the importance of working to correct social injustice. Despite these benefits, few instructors report that they integrate diversity-related content into their course curriculum, with many citing lack of knowledge for how to do this as a primary barrier. The purpose of this study is to assess student perceptions of diversity in the curriculum using both quantitative and qualitative methodology, with the broader goal of informing future curriculum design.
Student Satisfaction with Technology
- Cassady McLaughlinPsychologyGraduate Student
- Michael WilsonMathematicsUndergraduate Student
- David MarshallComputer ScienceFaculty
The purpose of this research is to assess HSU students’ satisfaction with the various services provided by the Information Technology Services department. The services that are being assessed are computers labs, on-campus printing, technology in the classroom, on-campus wi-fi, myHumboldt, HSU Gmail accounts, Google Drive, Google Calendar, Canvas, ITS Support, online classroom scheduling (via 25live), and the virtual labs (vlab.humboldt.edu). After completion of the survey, we hope to use the data to implement changes within the department in order to increase student satisfaction with the services mentioned above.
Students’ Experiences with Diversity, Equity, and Inclusion in Research Methods Courses

Researchers have noted a historical lack of coverage of diversity, equity, and inclusion (DEI) topics in Psychology Research Methods courses (RMCs). We hypothesize that Psychology RMCs’ coverage of DEI will be positively correlated with indicators of academic integration and negatively correlated with minority stress, especially for marginalized students (e.g., students of color). DEI in RMCs were associated with greater science identities and networking in white students and perceptions of positive campus climate for all students. However, for students of color, DEI in RMCs were associated with a greater number of social climate stresses. Given the small sample, more research is needed.
Studies of Bio-Sustainable Materials by Scanning Electron Microscopy
Priscilla Gamez, Chemistry Undergraduate Student
- FrankCappuccioBiological SciencesFaculty
Biomaterials derived from plants can provide stocks for biofuels and additives for sustainable bioplastic composites. Here, scanning electron microscopy (SEM) was used to image cellulase enzyme-exposed samples vs. controlled samples, which indicated cellulose degradation. SEM examination of PLA-quinoa composites indicated successful incorporation of quinoa chaff into these biodegradable plastics. This study of cellulase contributes to understanding its role in enhancing biofuel feedstock production. Moreover, our PLA-quinoa composites show promise as biodegradable and biorenewable materials. Future studies will analyze cellulase-treated PLA-quinoa composites.
Study of Hornblende Reaction Rims in Regard to Magma Rate Through the Conduit in California's Mt. Lassen's 1915 Eruption

Interpretation of hornblende reaction rims through the use of a scanning electron microscope to establish accent rate and path of magma through Mt. Lassen's volcanic conduit in the 1915 eruption.
Studying the Connection Between X-Ray and UV Absorption in AGN Outflows

- Cm AprilPhysics/AstronomyUndergraduate Student
- Michael GibbonsPhysics/AstronomyUndergraduate Student
- Paola Rodriguez-HidalgoPhysics/AstronomyFaculty
Active Galactic Nuclei are still somewhat of an enigma; young, bright galaxies with a large range of redshifts. Our current research is focused on gas outflows from the active galactic nucleus (AGN). These outflows are identified by broad absorption lines in the spectra of AGN. Current multi-epoch observations of many active galactic nuclei (AGN) have resulted in broad absorption lines that appear and disappear over time. Current observations show that these outflows have speeds up to 0.2c. Our team’s ultimate goal is to understand the mechanism that drives quasar outflows and characterize the broad spectral absorption lines, as well as why the outflows are variable
Stylohyoid-tympanic articulation in shrews and its possible implications for echolocation

Echolocation has evolved in several mammals, including shrews. In bats, echolocation may occur through the larynx via the stylohyoid-tympanic articulation (ST-A). Using CT scans, we studied the morphology of the inner ear to determine if the ST-A is present in echolocating shrews. Of the nine sampled genera, three have behavioral data suggesting echolocation. Six species presented ST-A, including four species not known to echolocate. Given the limited behavioral data and the small data set, a few interpretations are possible, all of which highlight the need for additional research in this understudied mammalian group in order to reveal the role of the ST-A in shrew echolocation.
