How Geek Therapy Plays Into Expressive Arts Therapy: A Literature Review

Within this paper, I explore how geek therapy plays well with the methods of expressive arts therapy. The combination of geek therapy and expressive arts therapy can assist clinicians in immediately connecting with their clients and identifying strength-oriented narratives that honor the client’s preferences, modes of expression, and pop culture affinities. This engagement with expressive approaches utilizing affinity-based interventions can lead to a deeper sense of understanding of the client’s intra-, inter-, and extra-personal relationships. Through this literature review of expressive arts therapy and geek therapy, primarily focusing on video games in therapy, clinicians from all walks of life can explore these techniques with clients in multiple settings and within a variety of age groups. Video games are immersive, multimodal, and interactive digital experiences that can promote wellness through engaging a spectrum of cognitive processes, regulating emotion and physical states, exploring meaning, identity, and expression, and building interpersonal tools through in-person and/or virtual means. This paper explores how video games can impact bio-psycho-sociocultural-spiritual domains as well as other potentially therapeutic characteristics of video gaming, whether through in-direct/direct or active/passive experiences. Through understanding gamer motivations, this paper explores player taxonomy models and profilers that can assist in gathering assessment information. Lastly, ethical considerations and the potential for maladaptive behaviors are explored

Designing a Student Exchange Program: Facilitating Interdisciplinary, Mathematics-Focused Collaboration among College Students

Interdisciplinary collaboration is necessary for students’ professional preparation (Laird et al., 2014; Repko, 2014) and may promote effective learning transfer of course content. Such collaborations have resulted in enhanced problem-solving skills and conceptual understanding of statistics content (Dierker et al., 2012; Everett, 2016; Hammersley et al., 2019; Woodzicka et al., 2015). As a result of ongoing collaborations between faculty members in different disciplines and at different universities, we created a “Student Exchange Program” to encourage interdisciplinary collaboration between undergraduate students in mathematics and social sciences. In the current paper, we describe past research that informed the design of this program, the specific steps taken to implement the program, preliminary results, and potential challenges to implementing and maintaining such an initiative

Epidemic dynamics of respiratory syncytial virus in current and future climates.

A key question for infectious disease dynamics is the impact of the climate on future burden. Here, we evaluate the climate drivers of respiratory syncytial virus (RSV), an important determinant of disease in young children. We combine a dataset of county-level observations from the US with state-level observations from Mexico, spanning much of the global range of climatological conditions. Using a combination of nonlinear epidemic models with statistical techniques, we find consistent patterns of climate drivers at a continental scale explaining latitudinal differences in the dynamics and timing of local epidemics. Strikingly, estimated effects of precipitation and humidity on transmission mirror prior results for influenza. We couple our model with projections for future climate, to show that temperature-driven increases to humidity may lead to a northward shift in the dynamic patterns observed and that the likelihood of severe outbreaks of RSV hinges on projections for extreme rainfall

Obliquity Constraints on an Extrasolar Planetary-Mass Companion

We place the first constraints on the obliquity of a planetary-mass companion outside of the solar system. Our target is the directly imaged system 2MASS J01225093–2439505 (2M0122), which consists of a 120 Myr 0.4 M⊙ star hosting a 12–27 M_J companion at 50 au. We constrain all three of the system's angular-momentum vectors: how the companion spin axis, the stellar spin axis, and the orbit normal are inclined relative to our line of sight. To accomplish this, we measure projected rotation rates (v sin i) for both the star and the companion using new near-infrared high-resolution spectra with NIRSPEC at Keck Observatory. We combine these with a new stellar photometric rotation period from TESS and a published companion rotation period from Hubble Space Telescope to obtain spin-axis inclinations for both objects. We also fitted multiple epochs of astrometry, including a new observation with NIRC2/Keck, to measure 2M0122b's orbital inclination. The three line-of-sight inclinations place limits on the true de-projected companion obliquity and stellar obliquity. We find that while the stellar obliquity marginally prefers alignment, the companion obliquity tentatively favors misalignment. We evaluate possible origin scenarios. While collisions, secular spin–orbit resonances, and Kozai–Lidov oscillations are unlikely, formation by gravitational instability in a gravito-turbulent disk—the scenario favored for brown dwarf companions to stars—appears promising

Formate Formation and Formate Conversion in Biological Fuels Production

Biomethanation is a mature technology for fuel production. Fourth generation biofuels research will focus on sequestering CO2 and providing carbon-neutral or carbon-negative strategies to cope with dwindling fossil fuel supplies and environmental impact. Formate is an important intermediate in the methanogenic breakdown of complex organic material and serves as an important precursor for biological fuels production in the form of methane, hydrogen, and potentially methanol. Formate is produced by either CoA-dependent cleavage of pyruvate or enzymatic reduction of CO2 in an NADH- or ferredoxin-dependent manner. Formate is consumed through oxidation to CO2 and H2 or can be further reduced via the Wood-Ljungdahl pathway for carbon fixation or industrially for the production of methanol. Here, we review the enzymes involved in the interconversion of formate and discuss potential applications for biofuels production

A Tale of Four Departments: Interdisciplinary Faculty Learning Communities Informing Mathematics Education

As a result of the Curriculum Foundations Project and the SUMMIT-P consortium, faculty from four different departments at Lee University created a Faculty Learning Community (FLC) with the goal of improving students’ attitudes toward undergraduate mathematics courses, including students’ perception of the utility of mathematics in their lives and the feelings of anxiety that they experience in these courses. The interdisciplinary collaborations resulted in introducing novel activities and manipulatives in various mathematics courses (Introduction to Statistics, Concepts of Mathematics I and II, and Algebra for Calculus). This paper first describes the efforts of creating the inter-departmental FLC. Second, it discusses the interventions that were introduced in the mathematics courses. Finally, it reflects on the lessons learned while participating in the learning community. The goal is to guide and challenge readers to consider how similar collaborative opportunities can be initiated at their own institutions
