The Benefits of Academically Oriented Peer Mentoring for At-Risk Student Populations

This article examines an academically oriented peer-mentoring program at St. John’s University. The program targeted at-risk first-year students who were having difficulty making the transition to college and matched them with trained student mentors within their major discipline. In addition to meeting with one another bi-weekly, all of the students came together for a series of organized events over the course of the academic year. The goals of the program were that mentees would (1) feel an increased sense of belonging at the university, (2) raise their GPAs, and (3) show improved retention to the second year. After examining how successful the program was relative to these goals, the authors recommend some best practices for peer-mentoring programs. These recommendations are based on both features of the program in the study that contributed to its success and areas where the program could have been improved based on the results. &nbsp

Variable Temperature Thermochromic Switching Under Varying Illumination

Award for Runner-Up Poster Presentation . Abstract Minnesota is home to some of the greatest temperature ranges in the United States, with lows reaching below -40º Celsius and highs reaching nearly 40ºC. This results in higher than average spending on the heating and cooling of buildings. We have been investigating into responsive building materials to help address this. In particular, we have been studying a thermochromic paint that can capture solar energy and transfer it into the building as heat at low temperatures and reflect the energy at higher temperatures to keep the building cooler

Dancing literacy: Expanding children’s and teachers’ literacy repertoires through embodied knowing

This paper explores dance as literacy. Specifically, it examines qualitative case study research findings and student examples from a dance artist-in-residence that explored curricular content using dance as its primary mode of inquiry and expression. Throughout the residency, students constructed meaning through their dance experiences in dynamic and autonomous ways, exhibiting complex literacy practices of inquiry and communication. Focusing on the kindergarten student participants’ experiences, the authors highlight three themes in their dance literacy practices: (a) artistic autonomy, (b) embodied knowledge, and (c) multimodality. As embodied knowledge, dance innately allowed for integrative literacy possibilities in the dance residency. The dance experiences observed and referenced in this research illustrate the complexities of dance as literacy, as both a unique literacy and in meaning-making across literacies. Drawing on the findings of this study, the authors seek to inspire teachers to foster similar experiences to develop transformative literacy practices individually in their classrooms and collaboratively in their schools

Changing the Face of STEM: Review of Literature on The Role of Mentors in the Success of Undergraduate Black Women in STEM Education

The lack of ethnic and gender diversity in STEM undergraduate programs may lead to diversity and equity issues in STEM careers. However, some research suggests that mentoring influences the career trajectory of Black undergraduate women students in STEM. The investigation into these phenomena highlights suggestions for future research on mentoring Black undergraduate women in STEM. More recently, empirical research on mentoring among Black women have gained some momentum. Furthermore, with the increasing diversity and inclusivity demands from #ShutdownSTEM, in support of the Black Lives Matter movement, there is a focus on correcting barriers to access in STEM. Therefore, this conceptual paper reviews the literature on mentoring undergraduate Black women in STEM, effective mentoring best practices, and future research and policymaking suggestions

The prevalence of cannabis use disorders in people who use medicinal cannabis : A systematic review and meta-analysis

Background The prevalence of cannabis use disorders (CUDs) in people who use cannabis recreationally has been estimated at 22%, yet there is a dearth of literature exploring CUDs among people who use medicinal cannabis. We aimed to systematically review the prevalence of CUDs in people who use medicinal cannabis. Methods In our systematic review and meta-analysis, we followed PRISMA guidelines and searched three databases (PsychInfo, Embase and PubMed) to identify studies examining the prevalence of CUDs in people who use medicinal cannabis. Meta-analyses were calculated on the prevalence of CUDs. Prevalence estimates were pooled across different prevalence periods using the DSM-IV and DSM-5. Results We conducted a systematic review of 14 eligible publications, assessing the prevalence of CUDs, providing data for 3681 participants from five different countries. The systematic review demonstrated that demographic factors, mental health disorders and the management of chronic pain with medicinal cannabis were associated with an elevated risk of CUDs. Meta-analyses were conducted on the prevalence of CUDs. For individuals using medicinal cannabis in the past 6–12 months, the prevalence of CUDs was 29% (95% CI: 21-38%) as per DSM-5 criteria. Similar prevalence was observed using DSM-IV (24%, CI: 14–38%) for the same period. When including all prevalence periods and using the DSM-5, the prevalence of CUDs in people who use medicinal cannabis was estimated at 25% (CI: 18-33%). Conclusions The prevalence of CUDs in people who use medicinal cannabis is substantial and comparable to people who use cannabis for recreational reasons, emphasizing the need for ongoing research to monitor the prevalence of CUDs in people who use medicinal cannabis

A mechanism with severing near barbed ends and annealing explains structure and dynamics of dendritic actin networks

Single molecule imaging has shown that part of actin disassembles within a few seconds after incorporation into the dendritic filament network in lamellipodia, suggestive of frequent destabilization near barbed ends. To investigate the mechanisms behind network remodeling, we created a stochastic model with polymerization, depolymerization, branching, capping, uncapping, severing, oligomer diffusion, annealing, and debranching. We find that filament severing, enhanced near barbed ends, can explain the single molecule actin lifetime distribution, if oligomer fragments reanneal to free ends with rate constants comparable to in vitro measurements. The same mechanism leads to actin networks consistent with measured filament, end, and branch concentrations. These networks undergo structural remodeling, leading to longer filaments away from the leading edge, at the +/- 35𝑜 orientation pattern. Imaging of actin speckle lifetimes at sub-second resolution verifies frequent disassembly of newly-assembled actin. We thus propose a unified mechanism that fits a diverse set of basic lamellipodia phenomenology

Mild propofol sedation reduces frontal lobe and thalamic cerebral blood flow: An arterial spin labeling study

Mechanisms of anesthetic drug-induced sedation and unconsciousness are still incompletely understood. Functional neuroimaging modalities provide a window to study brain function changes during anesthesia allowing us to explore the sequence of neuro-physiological changes associated with anesthesia. Cerebral perfusion change under an assumption of intact neurovascular coupling is an indicator of change in large-scale neural activity. In this experiment, we have investigated resting state cerebral blood flow (CBF) changes in the human brain during mild sedation, with propofol. Arterial spin labeling (ASL) provides a non-invasive, reliable, and robust means of measuring cerebral blood flow (CBF) and can therefore be used to investigate central drug effects. Mild propofol sedation-related CBF changes were studied at rest (n = 15), in a 3 T MR scanner using a PICORE-QUIPSS II ASL technique. CBF was reduced in bilateral paracingulate cortex, premotor cortex, Broca’s areas, right superior frontal gyrus and also the thalamus. This cerebral perfusion study demonstrates that propofol induces suppression of key cortical (frontal lobe) and subcortical (thalamus) regions during mild sedation

Understory 2014

“Art is the struggle to be, in a particular sort of way, virtuous.” —Iris Murdoch Indeed, when we embark on any creative adventure it is with the purpose of conveying a certain truth; an emotion, an idea that brings us together and reminds us of the innate consciousness that dwells within. Understory is emblematic of this; where individuals intent on honing their craft can join others to become a part of something greater, their work immortalized to become a time capsule. Decades from now a volume of Understory may be discovered on a dusty bookshelf in some forgotten corner and the lucky explorer who finds it shall be enlightened by pages of gold. We, as editors of Understory 2014, have worked very hard this year to put together a journal that showcases the very best of the University of Alaska Anchorage undergraduate student work. We hope you enjoy your journey through this issue as much as we have enjoyed ours. Thank you to the English and Art Departments, for the staff and faculty’s unerring support of our club; to Provost Baker, for seeing and believing in the vision of Understory; and to our club’s faculty advisor, Douglass Bourne, for his guidance and tireless assistance. Finally, thank you to the wonderful students who submit such excellent work each year. Without your passion for the arts, we would not be here.Staff / Letter from the Editors / Glass Blower / Writing / Obsolete Evolution / Permafrost / Phoenix / Untitled / Ratio / Tripping / Abiogenesis / My Heart Beats for You / Meeting of the Fingerprint Lines / You Are No Stranger / Nightmare Fuel / Cane-Sugar / Gossamer Strands / Panthera Gold / Butterfly / A Mantis Too Far / Long and Winding Road / Chasing Shadows / Merisunas / Chequer Grove / Modzilla / Beans / Little Red and Mr. Wolf / In Memoriam, Joel Fletcher Armstrong / Glance / Courage / Uranium Waltz / Danger / Journey to the West / Antumbra / Roaring Like a Lion / Pre-boarding / Untitled / How Do You Say a Word / Fishing for Doom/ Contributor
