Founded in 1851, Greenwood Cemetery is one of Humboldt County's oldest resting places, hosting hundreds, including veterans from the Civil War to modern conflicts. In preparation for Memorial Day, I've meticulously cleaned and mapped veteran gravestones over three months. This ensures accurate flag placement, honoring their service beyond symbolism. Let's preserve their legacies for generations to come.
How Ecological Restoration Affects Mammalian Species Diversity and Evenness in Coastal Dune Systems

I tested the effects of differning landscape management practices at two different coastal dune systems in Humboldt County , California. I did this to see how ecological restoration of native plant compositions affected mammalian species richness and evenness.
Burnout Syndrome an Occupational Hazard for Nurses

Burnout syndrome is an occupational hazard that can affect healthcare professionals, especially bedside nurses that work in a hospital setting. It is comprised of three main components; emotional exhaustion, depersonalization, and reduced professional efficacy. It occurs when healthcare workers experience chronic stress. It can lead to mental health issues such as depression, anxiety and PTSD. It negatively affects patient outcomes and patient satisfaction. It also increases nurse turnover which results in understaffing, therefore affecting patient safety. Improving working conditions for nurses, education and quality leadership will help decrease the prevalence of burnout syndrome.

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.
Comparing Male and Female Domestic Violence Offender Responses Regarding Experiences Related To Intimate Partner Violence

Historically, male violence has been viewed as a way to maintain power and control over a female partner within an intimate relationship while female violence has been viewed as a response to a male intimate partner’s attacks (Dobash & Dobash, 1979; Walker 1989). This community research project examines differences in attitudes and experiences related to violence among male and female domestic violence offenders. Individual interviews (N=13) were conducted to gain qualitative data specific to this topic. Participants included 5 men and 8 women enrolled in a 52-week batterer’s intervention program. The project findings will help guide a better understanding of family violence.

We found that not only did participants experiencing high self-uncertainty make fewer overall errors, but more interestingly, they demonstrated greater accuracy for self-relevant word-pairings than those low in uncertainty. This in turn affected reaction times pairing self-relevant vs. self-irrelevant words. This implies that uncertainty might not lead to cognitive load or distracted and heuristic processing. Instead, we suggest that uncertainty can create a motivated process with respect to self-relevant information, leading to more accurate judgments about the self, perhaps in an attempt to reduce uncertainty.
"Outdoorsy" Instagram Culture and 19th Century Art: Imperialism in Our National Parks

College of Arts, Humanities & Social Sciences
Curated "Outdoorsy" social media accounts rival 19th century idealized landscape paintings, allowing people to present themselves as adventurous and fulfilled by sharing beautiful photos from their travels. These visualized false landscapes present a new age of imperialist beliefs as themes of colonialism have continued to live on through generations in our culture. In western culture, landscape has often been seen as a commodity to be presented and reconstructed for our enjoyment throughout history. Although Instagram culture has contributed to many changes within our national parks, this “new” culture of objectifying and commodifying the landscape is really nothing new at all.

Anabaena Sensory Rhodopsin (ASR), a photoactive membrane protein, undergoes light induced conformational change associated with release of a transducer protein, ASRT. This complex is proposed to control transcription. However, DNA binding to ASR has not been demonstrated. We prepared ASR in soluble nanodiscs. Our data show ASR nanodiscs had a retinal absorbance shift (≈548 - 537 nm). DLS of ASR nanodiscs, separated by SEC, displayed two populations (21.9 ± 6.3 and 31.1 ± 12.5 nm). These populations may represent varying oligomeric states. Preliminary data from crosslinking studies suggest ASR exist in a trimeric state. We conclude ASR is stabilized in the nanodiscs, enabling studies of ASR.
