Quantification of Terpenes in Various Commercial Cannabis Products by Gas Chromatography-Flame Ionization Detection and Gas Chromatography-Mass Spectrometry
Full text linkThe goal of this research project was to identify and quantify the terpenes in five commercial cannabis products (dried bud, kief, two tinctures, and a pain cream) using gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Terpene identification and quantification were conducted using GC-MS and GC-FID, with a standard sample containing 21 terpenes of known concentrations. To determine the most effective extraction conditions, three organic solvents (ethanol, acetonitrile, and ethyl acetate) were employed. Additionally, the effects of extraction time on terpene yield were investigated by analyzing aliquots collected at five different time intervals, ranging from one hour to seven days post-extraction. The results revealed that terpene concentrations varied across the five cannabis products. Although numerous terpenes were detected, myrcene, limonene, caryophyllene oxide, α-humulene, linalool, eucalyptol, and nerolidol were identified as the major terpenes. In the solvent study, ethyl acetate proved to be the most effective extraction solvent, yielding 1.5 to 1.6 times higher terpene concentrations compared to ethanol and acetonitrile, respectively. In the extraction time study, it was found that terpene concentrations decreased over time, likely due to degradation. For the dried bud sample, the concentration of myrcene decreased fourfold after seven days compared to the concentration extracted after one hour
Innotivity
Full text linkThis Master’s project focuses on rewriting the text of the first half of the book Innotivity, outlining a framework that brings together adaptability, creativity, and innovation (ACI) into a unified process. The approach explores how identity shapes creative potential and problem-solving, an aspect often overlooked in traditional creativity models. The project entails two parts: first, the text analysis and rewrite, and second, a series of feedback sessions with creativity experts to vet the model.
The project builds on the author\u27s extensive experience in creativity training and coaching, with the goal of making Innotivity more theoretically sound and academically defensible. It situates Innotivity within established mainstream creativity theories as well as more recent and esoteric ones, investigating particularly the gaps in understanding how identity influences creative blockages and breakthroughs.
Ultimately, this project aims to bring the text of the theoretical portion of the book Innotivity to a level at which it is ready for a final edit round and then publication, as a foundation for also rewriting the second, more practical part of the book. By redefining creativity through the lens of identity, Innotivity offers an approach to unlocking human potential in an era of constant change based on both structure and flexibility
Rebooting a Foundational Reading Program with Recent Evidence from the Science of Reading
Full text linkThe Science of Reading (SOR) movement has reshaped literacy education, emphasizing evidence-based instructional materials and practices. School districts have been propelled to evaluate existing instructional materials and to consider adopting new reading programs. This article examines how Road to Reading (RTR), an evidence-based program that aligns with the SOR focus on phonics and word recognition, can be updated to reflect newer research. Rather than a full overhaul, this paper proposes a “reboot”— targeted updates that refine the five-step lesson structure. Key improvements include expanded assessments, phonemic awareness integration, motivational supports, and instructional scaffolds to better meet diverse learner needs.These targeted updates preserve the integrity of RTR while ensuring its continued effectiveness in contemporary classrooms. Moreover, this reboot model can be applied to other phonics-based programs as teachers strive to balance established literacy practices with evolving research findings
Technical Study and Conservation Treatment of a Painted Wooden Figure, attributed as an 18th-Century American Sternboard
Full text linkThis study focuses on the investigation of an object owned by the Memorial Art Gallery (MAG) that was cataloged as an 18th -century American sternboard. The MAG shared concerns regarding the object’s provenance and whether the object was correctly identified. Technical analysis, including multimodal photography, x-ray fluorescence spectroscopy (XRF), scanning electron microscopy with energy dispersive x-ray spectroscopy (SEM/EDX) and wood identification, was conducted to inform the museum on the fabrication of the object and on its material components. The information collected was examined alongside historical research regarding the authenticity of the provenance, aiming to better understand the nature of the object. The research did not yield any historical evidence supporting the provenance, and it was noted that the object does not conform to sternboard conventions. Additionally, there is evidence of restorations or alterations, including a modern paint campaign that postdates the 18th century, leaving the object\u27s identity unresolved. These findings guided the decision to proceed with minimal treatment, focusing on surface cleaning and stabilization
Supporting the “Feelings and Language of Thinking” and Meaning-Making in Elementary Student-Directed Inquiry Projects
Full text linkThis qualitative study investigates how three teachers attend to and pedagogically support socioemotional aspects of fifth-grade students’ learning during student self-directed inquiry projects called the Kids Inquiry Conference (KIC) using Spradley’s domain and taxonomic analyses of classroom observation and interview data. Theoretical underpinnings meet at the intersection of affective neuroscience, socioemotional competencies, and a Deweyan perspective of inquiry learning, emplacing this study within literature exploring the range of affective factors impacting elementary learners engaged in student-centered inquiry projects (e.g., identity work, motivation, self-regulation, etc.). KIC involved students self-selecting and developing research questions, designing a science activity, writing up a scientific article, and giving a multimodal presentation of their findings. Findings focused on teachers recognizing and supporting students’ increased emotional vulnerability in self-directed inquiry learning, teaching language to support feeling while thinking, and providing pedagogical supports for emotions and feelings involved with inquiry learning. In short, if we are to enable our students’ agency and autonomy in such self-directed inquiries into the world around them, we must first recognize and support their emotional realities in our classrooms
Using Facebook to Discuss the Science of Reading
Full text linkStudents in U.S. elementary schools continue to experience difficulty learning to read, with some attributing these difficulties to a lack of alignment with the Science of Reading (SOR). Social media plays a prominent role in disseminating information about the SOR, serving as a platform for discussion and debate that reflects many tenets of effective online professional development (OPD). The current study examines how one group of educators on social media sought out and discussed information related to the SOR. Content analysis was utilized to determine how contributors engaged with the group and what pedagogical content knowledge and SOR topics were addressed in alignment with two major tenets of effective OPD. Our analyses revealed a relatively large number of educators participated minimally, most often requesting suggestions for phonics-focused material. Posts were mostly neutral or positive in tone, with the majority functioning as lists rather than discussions. Research was rarely cited to support assertions or suggestions. Analyses reveal the group functions primarily as a triage site rather than as an effective OPD venue. Findings are discussed in relation to future directions and critiques of using social media as OPD to understand the SOR

Comparisons of Terpenes in Cannabis Flowers via Gas Chromatography-Flame Ionization Detection and Gas Chromatography-Mass Spectrometry
No full textThe increasing legalization of recreational cannabis across the United States has resulted in the rapid growth of cultivators, processors, and dispensaries offering a wide variety of cannabis products. In response, federal and state agencies have implemented policies that require rigorous laboratory testing of commercial cannabis. These tests typically include the quantification of specific cannabinoids, terpene profiling, and the detection of residual pesticides and heavy metals.
This research project focuses on the identification and quantification of terpenes in four commercially available cannabis flower strains using gas chromatography–flame ionization detection (GC-FID) and gas chromatography–mass spectrometry (GC-MS). To determine the most effective extraction solvent, three organic solvents – ethanol, acetonitrile, and ethyl acetate – were evaluated. Additionally, the effects of extraction time on terpene extraction were investigated by analyzing aliquots collected at five different time intervals, ranging from one hour to seven days after sample preparation. The results indicated that extracted terpenes and their concentrations varied among the different cannabis strains, with β-caryophyllene identified as one of the most prevalent terpenes, with concentrations ranging from 170.7 – 2674.6 μg/g. Among the solvents tested, ethyl acetate proved to be the most efficient, yielding terpene concentrations approximately 1.35 and 1.27 times higher than those extracted with ethanol and acetonitrile, respectively. Furthermore, terpene concentrations declined over time, with an approximate 1.5-fold decrease observed between 48 hours and seven days of extraction, regardless of the solvent used. This was presumably due to the degradation of extracted terpenes over the time
