Nature Healing Mental Stress: What U.S. Healthcare Can Learn From Other Nations, Shannon Frank-Richter, Lindsay Gietzen

Pacific Journal of Health

The United States healthcare system lags many developed nations in healthcare access and practices, especially surrounding ecotherapy [1]. Ecotherapy is the practice of mindfulness in tandem with intentional immersion among natural spaces or with natural elements. Research from Asia, Europe and Canada indicate immense benefits from ecotherapy, or mindful nature immersion, as an effective treatment for burnout and stress. By adopting regular nature engagement, the U.S. could significantly improve mental health and reduce occupational stress. This literature review examines how nature immersion, especially with mindfulness, positively affects the brain and nervous system. Key components in nature are identified, such as …

Water In The Middle East. A Geographyof Peace By A. Amery And Arron T. Wolf (Eds.)., C. Nicholas Raphael

The Geographical Bulletin

Despite the image that "it is all the same" the Middle East is a paradox in context and poorly understood. Oil rich and the center of three monotheistic religions in the Middle East contrast with political disarray and the availability of resources such as water. The arid empty 61 spaces contrast with the urbanization occurring throughout the region

Seeing The Blind: Humanism And The Experience Of Place, Joshua F. J Inwood

The Geographical Bulletin

Since much of our world is visually based, many researchers question how the "non-sighted " fit into this larger framework. Whereas many geographers have looked at navigation this paper will explore how the blind ascribe a practical understanding of the world that is constructed largely by and for those with sight. Because much of the relevant data involve perceptions not easily understood, this paper relies on qualitative methods, specifically the open-ended interview, to construct personal narratives. These narratives are analyzed using a humanistic perspective.

An Analysis Of Attacks By Grizzly Bears (Ursus Arctos Horribi/Is) In Glacier National Park, Montana, Lisa M. Dechano, David R. Butler

The Geographical Bulletin

Grizzly bears inhabit several popular recreation areas in the American West, including Glacier National Park, Montana. The likelihood of a grizzly bear-human confrontation increases as annual visitation continues to increase.

Pink1-Deficiency Facilitates Mitochondrial Iron Accumulation And Colon Tumorigenesis, Mariella Arcos, Lavanya Goodla, Hyeoncheol Kim, Sharina P. Desai, Rui Liu, Kunlun Yin, Zhaoli Liu, David R. Martin, Xiang Xue

Pathology Research and Scholarship

Mitophagy, the process by which cells eliminate damaged mitochondria, is mediated by PINK1 (PTEN induced kinase 1). Our recent research indicates that PINK1 functions as a tumor suppressor in colorectal cancer by regulating cellular metabolism. Interestingly, PINK1 ablation activated the NLRP3 (NLR family pyrin domain containing 3) inflammasome, releasing IL1B (interleukin 1 beta). However, inhibiting the NLRP3-IL1B signaling pathway with an IL1R (interleukin 1 receptor) antagonist or NLRP3 inhibitor did not hinder colon tumor growth after PINK1 loss. To identify druggable targets in PINK1-deficient tumors, ribonucleic acid sequencing analysis was performed on colon tumors from pink1 knockout and wild-type mice. …

The Farmer Stress Production Meeting Model: Acceptability And Feasibility Of An Intervention, Anna Scheyett, Andrea Scarrow, Jennifer Dunn, Stephanie Hollifield, Justin Shealey, Brian Hayes

Journal of Extension

Farmers experience high stress levels, but are often reluctant to participate in mental health-specific programming. We tested providing stress supports to farmers by embedding information and resources within existing Extension production meetings. During meetings, farmers were offered blood pressure screenings where providers would also discuss stress; were offered an information packet on stress and health, and listened to a brief talk from a therapist with local roots. Farmers accepted screenings and resources, and several later contacted the therapist. Extension agents, initially cautious about addressing the topic of farmer stress, expressed greater confidence in talking about the issue after these meetings.

The Challenges Of Co-Developing Climate-Smart Strategies, Practices, And Technologies Among Research And Extension Teams, Michelle R. Worosz, Hannah Stewart, Mckayla Robinette, Brenda Ortiz, Rishi Prasad, Audrey Gambel, Leah Duzy

Journal of Extension

With climate-smart agriculture as the context, we explore one aspect of transdisciplinarity, the co-development of knowledge (CDK). Challenges were identified via matrix coding and word frequency queries of field day, meeting, and interview transcripts. Focusing on the Research-Extension team, we found they highly value collaboration and participatory-based projects, but developing trust-based relationships, enhancing long-term stakeholder investment, and understanding both team and stakeholder capacity was difficult. This paper informs transdisciplinary projects aimed at climate adaptation by illustrating the need for Research-Extension teams to take incremental steps towards CDK, to engage stakeholders before program planning, and to increase both interaction and reflexivity.

Nusap4 Regulates Chromosome Segregation In Trypanosoma Brucei By Promoting Bipolar Spindle Assembly, Qing Zhou, Ziyin Li

Faculty, Staff and Student Publications

Faithful chromosome segregation in eukaryotes requires the assembly of a bipolar spindle and the faithful attachment of kinetochores to spindle microtubules, which are regulated by various spindle-associated proteins (SAPs) that play distinct functions in regulating spindle dynamics and microtubule-kinetochore attachment. The protozoan parasite Trypanosoma brucei employs evolutionarily conserved and kinetoplastid-specific proteins, including some kinetoplastid-specific nucleus- and spindle-associated proteins (NuSAPs), to regulate chromosome segregation. Here, we characterized NuSAP4 and its functional interplay with diverse SAPs in promoting chromosome segregation in T. brucei. NuSAP4 associates with the spindle during mitosis and concentrates at spindle poles where it interacts with SPB1 and MAP103. …

Impact Of Stolon Removal On Yield And Fruit Quality Of Day-Neutral Fragaria X Ananassa “Cabrillo” Grown In Outdoor Soilless Conditions, Kate Fessler, Emily E. Hoover, Neil O. Anderson

Journal of Extension

Strawberries are among the most consumed fruits in the U.S. and demand for locally grown fruit is high. Although most production in Minnesota is dominated by June-bearers, new techniques for growing day-neutral strawberries are becoming increasingly prevalent. These techniques include in-ground plasticulture and soilless tabletop production, and growers are generally advised to remove stolons (runners) from day-neutral plants. There is relatively little information available to confirm that this practice, and its attendant labor increase, is a necessity in soilless tabletop production. This study’s objective was to determine whether this practice is necessary to maximize yield and fruit quality, using the …

Management Of The Invasive Honeysuckle (Lonicera Maackii), Mesa Grine, Daniel Hazelett, Cassie Healy, Padma Deepika Kandregula

Runkle Woods Symposia

This presentation addresses the ecological threat posed by invasive honeysuckle in the Runkle Woods on Wright State's campus. Originally from Europe and Asia, honeysuckle aggressively outcompetes native flora due to its rapid growth, shade tolerance, and allelopathic properties. The students observed widespread honeysuckle in both new and old growth forest areas, with greater density in younger regions. Ineffective control methods—such as cutting without herbicide—often worsen infestations. Drawing on a regional study, the students propose a targeted management plan involving cutting and herbicide application, stem injection for larger plants, and reintroducing native species like spicebush. Their strategy aims to reduce honeysuckle …

Old Growth In The Runkle Woods, Madeline Greene, Lindsay Smith, Matt Tyren, Leif Walters

In this conservation proposal, Wright State students focus on protecting the old growth areas of Runkle Woods—a rare and ecologically significant habitat in the Eastern United States, where only about 1% of such forests remain. Home to trees over 200 years old and critical species like endangered bats and white oaks, this 100-acre area faces threats from invasive species, deer overpopulation, littering, and urban runoff. Currently, only 15 acres are legally protected. The students propose expanding the easement, involving experts and graduate students in ongoing research and stewardship, and increasing public engagement through educational walks and increased and updated signage. …

Up In Smoke: Indigenous Techniques To Combat Climate Change And Increase Biodiversity, Brad Kerry

Runkle Woods Symposia

Brad Kerry explores how Indigenous land management practices—particularly the use of prescribed fire—can be reintroduced to restore the Runkle Woods to its pre-colonial ecological state. Drawing on archaeological evidence, historical tree surveys, and ecological data, the presentation highlights how periodic, low-intensity fires historically maintained the forest’s biodiversity, promoted fire-adapted species like oak and hickory, and suppressed invasive plants. Kerry advocates for carefully planned, small-scale burns to combat "mesophication"—a shift toward shade-tolerant, fire-averse species—while increasing forest resilience to drought, invasive species, and climate change. The presentation underscores the ecological benefits of fire and outlines practical considerations for reintroducing controlled burns as …
