“Not Conducive To Good Education”: Insights From Interviews With High School Math Teachers About The Academic Impacts Of Covid-19 In The Classroom, Thomas G. Holtmeier, Brook K. Batch, Rebecca J. Allen

Mid-Western Educational Researcher

This study explores the academic impacts of COVID-19 and virtual learning on high school math students in the United States. Previous research has found that COVID-19 led to significant declines in engagement and test scores, alongside a widening opportunity gap among students of different backgrounds. This study interviewed high school math teachers from two private schools to understand what they have observed of students both during the pandemic and now. The findings reveal that the virtual learning experience had a limited negative impact on most students in these two schools, but teachers expressed concerns about the limitations of the …

Comparison Of Kinematic Outputs And Reliability Of Plug-In Gait Versus Conventional Gait Model 2 During Cycling, Erin Mccallister, Nicholas Russell

International Journal of Exercise Science

International Journal of Exercise Science 18(7): 712-726, 2025. Motion analysis is used to measure proper bicycle fit, avoid injury, and improve cycling performance. Small changes in position can impact joint kinematics and risk for overuse injury. Concerns regarding the often-used biomechanical model Plug-in-Gait (PIG) resulted in the creation of Conventional Gait Model 2 (CGM2). This study aims to compare kinematic outputs of these two models for cycling biomechanics plus between-day reliability of each model. Thirty-five participants participated in two experimental sessions. PiG and CGM2 marker sets were applied, and data was collected while cycling between 80-90 rpm. Model outputs were …

A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin

The Great Lakes Entomologist

Diameter at breast height (dbh) , of ten tree parameters tested, was most highly correlated with the number of shoots per tree in six red pine plantations in the central Wisconsin sand plains. Tree height, frequently used as an estimator of shoot number in young conifers, was not highly correlated with shoot number. A strong, nonlinear correlation existed between branch diameter and number of shoots per branch. Multiple regressions using several tree parameters yielded the highest R2 values, however, dbh was judged the simplest and most practical estimator of shoot number for central Wisconsin red pine plantations.

Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default

The Great Lakes Entomologist

Broccoli plants were artificially defoliated at varying plant growth stages and defoliation intensities to determine bases for control decisions with lepidopterous defoliators. Low levels of defoliation (<25%) did not significantly depress head weight at any treatment date. Higher levels of defoliation severity (50%) depressed head weight when inflicted following the development of small (<2 cm) heads. Only complete defoliation (100%) consistently affected head weights. Because of the great ability of broccoli plants to compensate for leaf loss, most pre heading insecticide applications should be able to be eliminated in Minnesota without yield losses.

Sewage Sludge Application Linked To Increase In Eastern Tent Caterpillar Populations (Lepidoptera: Lasiocampidae), Louis F. Wilson, John H. Cooley, William J. Mattson

The Great Lakes Entomologist

Numbers of Malacosoma americanum caterpillar tents were positively correlated with average numbers and biomass of cherry trees as well as with amount of sludge applied. The enhancing effect of sewage sludge on amounts of black cherry biomass and foliar nitrogen may have been the principal factors leading to higher tent caterpillar populations on fertilized plots.

The Great Lakes Entomologist

The components of the nesting and provisioning behavior of Calicurgus hyalinatus are delineated chronologically. The unique cachement of the prey, whereby the spider is suspended from vegetation by its own silken threads, is described. The nesting and provisioning components we observed are compared with those described in the Nearctic and Palearctic literature.

Cleptes Speciosus In The Great Lakes Region (Hymenoptera: Chrysididae: Cleptinae), Mark F. O'Brien

The Great Lakes Entomologist

Cleptes (Melanocleptes) speciosus Aaron is newly recorded from Michigan, with records from five counties in the Upper and Lower peninsulas. A New York record from near Lake Ontario suggests this western species also has a Great Lakes distribution.

Nearctic Epiblema: A New Synonymy, A Revised Identity, And Two New Species (Lepidoptera: Tortricidae), William E. Miller

The Great Lakes Entomologist

New findings are reported for four species: Epiblema naoma Clarke is a junior synonym of E. iowana McDunnough; E. numerosana (Zeller) is currently misidentified; E. chromata, currently identified as the preceding, is described from Texas and differentiated from E. grossbecki Heinrich by maculation and female genitalia; and E. arctica, recently discovered in the Alaskan tundra, is described and differentiated from the boreal E. lyallana McDunnough by maculation and male genitalia.

Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie

The Great Lakes Entomologist

The cold hardiness of 'Winoka' and 'Genesee' winter wheats was each significantly less (P = 0.05) when fed upon by bird-cherry oat aphids, Rhopalosiphum padi, than non-infested seedlings. Aphid feeding also reduced the amount of fructans in crown tissue ca. 20% compared to extracts from crowns of non-infested seedlings. It appears that the cold hardiness of these wheat cultivars may have been reduced because of fructan depletion by insect feeding.

Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster

The Great Lakes Entomologist

llyadaphis tataricae causes witches-brooming to the growing tips of Zabelii and other large bush-type honeysuckles in the north central states. Insecticide tests show that acephate (Orthene), dimethoate (Cygan), or oxydemeton-methyl (Metasystox-R) sprayed monthly in June and July will reduce witches-brooming. Malathion was not effective in reducing damage. Host plant resistance observations indicate that Lonicera x notha, L. x muendeniensis, L. x amoena 'Alba', L. x ).;ylosteoides, and L. tatarica 'Arnold Red' are ll. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.

Vulnerability Of Hybrid Populus Nursery Stock To Injury By The Tarnished Plant Bug, Lygus Lineolaris (Hemiptera: Miridae), Louis F. Wilson, Lincoln M. Moore

The Great Lakes Entomologist

The tarnished plant bug injured 21 Populus clones in the clonal nursery of the Packaging Corporation of America in Michigan. Degree of injury ranged from 0.5 to 81.09<. Clone 'Wisconsin 5' sustained the heaviest attack, followed by Imperial Carolina poplar. 'Wisconsin 5' was salvaged by changing the standard and accepting shorter cutting stock for outplanting.

Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver

The Great Lakes Entomologist

[Excerpt] Interspecific interactions are relatively rare among coinhabiting Orthoptera. Most records are of overzealous males courting females not of their species or, for that matter, inanimate objects. Less frequent are reports of two signalling males interacting, yet these are of interest. Calling songs are used to distinguish species (Alexander 1956). The possibility then exists that the "interference" or, more correctly, the competition for broadcast space that occurs when two closely related species with similar songs interact, may have been influential in shaping aspects of song delivery or pattern.

State Records And Confirmations Of Odonata From Illinois And Missouri, T. E. Vogt, J. E. Mcpherson

The Great Lakes Entomologist

The occurrence of several species of Odonata in Illinois and Missouri is reported for the first time including Telebasis byersi Westfall, Tachopteryx thoreyi (Hagen), Aeshna mutata Hagen, Celithemis fasciata Kirby, fodona deplanata (Rambur), and Dythemis fugax Hagen for Illinois; and Cordulegaster obliqua (Say), Gomphus quadricolor Walsh, Helocordulia uhleri (Selys), C. fasciata, and C. verna Pritchard for Missouri. Also, the presence of several species is confirmed including Archilestes grandis (Rambur), C. obliqua. Hagenius brevistylus Selys, and Anax longipes Hagen for Illinois; and Lestes eurinus Say, H. brevistylus, Stylogomphus albistylus (Hagen), Arigomphus villosipes (Selys), A. longipes, and L. deplanata for Missouri.

Systematics Of Anepeorus (Ephemeroptera: Heptageniidae), W. P. Mccafferty, A. V. Provonsha

The Great Lakes Entomologist

The enigmatic genus Anepeorus has a confused and complex taxonomic history that is discussed and clarified. The genus is redefined and described in the adult stage. Although laryae have been assigned to Anepeorus, these larvae cannot be shown at the present to be Atnepeorus. Two North American species are known from a total of 10 adult specimens . . -tnepeorus rusticus McDunnough and A. simplex (Walsh) are redescribed, and a neotype is designated for the latter species. Genitalic differences are diagnostic, but the penes may be found in different states of inflation and rotation that should not be interpreted as …

A Decade-Wide View Into Medical Student Professional Identity Formation Using The Career Eulogy: Are Gen Zs Different?, William J. Crump Md, Kristin L. Wickham Md, Craig Ziegler Phd, Nicholas T. Duncan Mba, Mph

Marshall Journal of Medicine

Introduction

Students born after 1996 (Gen Z) perceive themselves as distinct from millennials. Earlier surveys described Gen Z as valuing relationships, meaningful work, financial security, and happiness. Over the past decade, medical school populations have shifted from predominantly millennial to Gen Z. This study examined changes in professional identity formation across this period, using a validated career eulogy instrument.

Methods

From 2015 to 2024, 113 medical students at a rural regional medical school completed an annual career eulogy (98% participation). Students responded to the prompt: “Imagine you are retiring from medicine. In about 50 words, what would you like to …

The Glymphatic System And Sleep: Functional Relevance For Brain Homeostasis And Beyond, David Gozal

Marshall Journal of Medicine

It has been less than 15 years since the glymphatic system was identified. The discovery has revolutionized the understanding of the unique functions of cerebrospinal fluid (CSF) and the extracellular fluid within the central nervous system (CNS) and their unique connectivity to the rest of the body. The role of sleep in regulating glymphatic clearance from the brain and the potential reciprocal role of the glymphatic system in modulating regional neuronal activities, including sleep states, is rapidly emerging. It is shedding light on the role of sleep and the glymphatic system as toxic waste clearance facilitators for the brain, revealing …

Unusual Wave Morphologies In Ulnar Neuropathy With Marinacci Anastomosis: A Case Report, Micaela Owens

Marshall Journal of Medicine

Marinacci anastomosis is a normal but rare anatomic variant of the median and ulnar nerves, consisting of an interconnection from the ulnar nerve to the median nerve within the proximal forearm. This is a case of Marinacci anastomosis occurring in the presence of both median and ulnar neuropathies, producing unusual waveform characteristics. Knowledge of normal anatomic variation can improve diagnostic accuracy in nerve conduction studies.

Ruptured Internal Mammary Artery Perforator After Reduction Mammoplasty: A Case Report, Carol Wright Becker, Abigail Roop, Daniel Sutphin, Roger Tillotson

Marshall Journal of Medicine

A 60-year-old female who was 10 days post-reduction mammoplasty presented to the emergency department due to the sudden onset of swelling and pain in her left breast. A contrast-enhanced CT scan of the chest revealed active arterial bleeding. The patient was emergently taken to the operating room, where she underwent evacuation of a large hematoma as well as ligation of a left internal mammary perforator artery. This case represents a rare occurrence of life-threatening postoperative bleeding into the chest wall/breast after reduction mammoplasty, which developed 10 days postoperatively. The successful outcome and complete recovery were attributed to the timely recognition …

Use Of Naltrexone For Treating Binge Eating And Food Obsession Related To Trauma: A Case Report And Literature Review, Rebecca K. Hicks, Iram Kingson, Jordan Gaal, Suzanne Holroyd

Marshall Journal of Medicine

Impulse-control disorders, including those related to eating behaviors, are complex conditions with limited pharmacologic treatment options. While naltrexone is primarily used for opioid and alcohol dependence, emerging research suggests it may also be effective in managing a variety of impulse-driven conditions. As a pure opioid antagonist, naltrexone’s mechanism of action involves the inhibition of opioid receptors on dopaminergic neurons involved in the reward pathway of the brain, thereby reducing the reinforcing effects of substances such as alcohol and opioids. Research suggests that through this mechanism of action, naltrexone shows promise in treating impulsive behaviors also driven by the reward pathway, …

Potential Impact Of Artificial Intelligence In Cardiovascular Medicine, Katherine Konczak, Elizabeth G. Dieter, Robert S. Dieter Ii, Robert S. Dieter Md, Rvt, Alm, Aravinda Nanjundappa Md

Marshall Journal of Medicine

Artificial intelligence (AI), particularly machine learning (ML), is increasingly transforming cardiovascular medicine by enhancing diagnostic accuracy, imaging analysis, risk prediction, and treatment planning. AI applications in imaging, such as echocardiography, cardiac computed tomography (CT), and magnetic resonance imaging (MRI), improve detection, automate measurements, and reduce variability. Deep learning models interpret electrocardiograms (ECGs) with high accuracy in electrophysiology, aiding early diagnosis of arrhythmias and inherited syndromes. In cardio-oncology, AI identifies cardiovascular risk markers in cancer patients and monitors therapy-related cardiotoxicity. AI-driven tools also support real-time procedural guidance and individualized therapy using electronic health records and imaging data. Despite promising outcomes, concerns …

Will There Be A Pill For That? ‘Money Dysmorphia’ And The Medicalization Of Struggles For Subsistence, Bojan Savic

Emancipations: A Journal of Critical Social Analysis

This article questions the rationality, operation, and effects of money dysmorphia as an emerging mental health diagnosis. It critiques the medicalization of financial angst amid the capitalist “polycrisis”, showing how the individuation and somatic pathologization of class subordination, socioeconomic precarity, and struggles for subsistence obscure capitalist inequalities, depoliticize them, and shield them from critique. I identify five concurrent strategies through which struggles for subsistence are medicalized: trivialization, reversal of social import, repetition, direct depoliticization, and the substitution of inequality with poverty. Furthermore, I show how the medicalizing discourse reifies money dysmorphia by constructing its social costs. The article concludes by …

Progress And Regression, Modernity And Social Evolution, José Maurício Domingues

Emancipations: A Journal of Critical Social Analysis

This paper deals with progress and evolution. Regarding progress, it in particular critically engages with recent works (Wagner, Allen, Jaeggi), arguing that we need a more assertive perspective. Our immersion in an evolutionarily and contingently created but globally established (modern) imaginary is found to underpin that more assertive perspective of progress. To articulate its perspective more generally, the paper draws upon a former elaboration on evolutionary homology and homoplasy regarding power. Thereby it tackles the development of morals/ethics, leading to a discussion of progress – and regression – including but going beyond material and cognitive issues. It grapples with evolutionary …
