Identifying Struggling Readers in Middle School with ORF, Maze and Prior Year Assessment Data

Response to Intervention (RTI) is a framework with the primary purpose of early identification and prevention of learning problems. Screening procedures identify students in need of targeted intervention, but current screening research is limited to the elementary grades. This study explored the use of screening measures: prior year assessment data, oral reading fluency (ORF), and maze, to predict performance on Georgia’s Criterion-Referenced Competency Test (CRCT-8) for 236 eighth grade students from one district in Georgia. Logistic regression analyses compared the accuracy of the predictor variables. Overall classification accuracy was 96.6% for ORF and maze and 97.1% for CRCT-7; however, this was primarily due to the low base rate of poor performance on the CRCT-8 in the sample. A combination of screens did not significantly improve classification accuracy. A screening process that used CRCT-7 data followed by fall ORF resulted in 100% sensitivity and 90% specificity. Implications for practice are discussed

Paul Austin Johnsgard: Memories of an Exceptional Naturalist

On May 28, 2021 the world lost one of its most dogged advocates, and we lost an amazing teacher, naturalist, and friend. Paul has told you in his own words in the previous pages where he was from, where he was educated, about the immense number of scholarly articles and books he published, and about his beautiful art that brought the wild to all of us (https://digitalcommons.unl.edu/zeabook/30/), but we wanted to share the person we knew Paul to be, and to relive some of our memories of him. While Paul’s body of work will continue to impact the ornithological and scientific communities for years to come, the man that Paul was – enthusiastic, caring, and deeply passionate about the natural world – changed the lives of everyone he met, and that too deserves celebration. Paul was the pre-eminent teacher. As a professor at the University of Nebraska-Lincoln (UNL), he taught many university students, and through his writings, he reached even more people beyond the university. There are many of us who met him on the Platte River and had the opportunity to learn from him there, and to take the enthusiasm and love he had for the ecology of the Great Plains and spread it to our own friends and family. For the two of us, Paul was never officially our teacher, but our meeting on the Platte helped to shape our love of Nebraska’s wild places, influenced our science, and provided a model for how we share knowledge with others

Haemosporidian parasite diversity in an under-surveyed Australian avifauna

Haemosporidian parasites of birds are geographically widespread, have been detected in a phylogenetically diverse array of hosts, and have been the focus of extensive research due to both their impacts on birds and their similarity to vector-borne diseases of humans. Advances in molecular diagnostic tools have created a greater awareness of the genetic diversity of haemosporidian infections. Yet in spite of their more or less global distribution, comparatively little is known about the haemosporidians affecting birds in Australia. We screened blood from 889 birds (23 species) for haemosporidian blood parasite infections during the 2019 breeding season at Brookfield Conservation Park, South Australia. We examined the genetic (lineage) diversity of haemosporidian infections in this behaviorally and ecologically diverse host assemblage and examined the congruence between parasite and host phylogenies. We identified seven Haemoproteus mitochondrial cytochrome b lineages, five of which were novel. Four birds had simultaneous co-infections by two Haemoproteus lineages each. The Haemoproteus lineages clustered at the host family level. Two Plasmodium lineages were also identified, each of which had been previously detected in different avian host species in Australasia. We did not detect any Leucocytozoon infections in our sample. This study supplies critical baseline data on host–parasite associations in a poorly-surveyed geographic region

Validation of spallation neutron production and propagation within Geant4

Using simulations to understand backgrounds from muon-induced neutrons is important in designing next-generation low-background underground experiments. Validation of relevant physics within the Geant4 simulation package has been completed by comparing to data from two recent experiments. Verification focused on the production and propagation of neutrons at energies important to underground experiments. Discrepancies were observed between experimental data and the simulation. Techniques were explored to correct for these discrepancies.Comment: 12 pages, 6 figures, 5 tables, submitted to NIM A. 6 Aug 200

Gill's model of the Antarctic Circumpolar Current, revisited: the role of latitudinal variations in wind stress

Adrian Gill’s (1968) model of the Antarctic Circumpolar Current (ACC) is reinterpreted for a stratified, reduced-gravity ocean, where the barotropic streamfunction is replaced by the pycnocline depth, and the bottom drag coefficient by the Gent and McWilliams eddy diffusivity. The resultant model gives a simple description of the lateral structure of the ACC that is consistent with contemporary descriptions of ACC dynamics. The model is used to investigate and interpret the sensitivity of the ACC to the latitudinal profile of the surface wind stress. A substantial ACC remains when the wind jet is shifted north of the model Drake Passage, even by several thousand kilometers. The integral of the wind stress over the circumpolar streamlines is found to be a useful predictor of the magnitude of the volume transport through the model Drake Passage, although it is necessary to correct for basin-wide zonal pressure gradients in order to obtain good quantitative agreement

Phenotypic diversity in an international Cure VCP Disease registry

BACKGROUND: Dominant mutations in valosin-containing protein (VCP) gene cause an adult onset inclusion body myopathy, Paget\u27s disease of bone, and frontotemporal dementia also termed multisystem proteinopathy (MSP). The genotype-phenotype relationships in VCP-related MSP are still being defined; in order to understand this better, we investigated the phenotypic diversity and patterns of weakness in the Cure VCP Disease Patient Registry. METHODS: Cure VCP Disease, Inc. was founded in 2018 for the purpose of connecting patients with VCP gene mutations and researchers to help advance treatments and cures. Cure VCP Disease Patient Registry is maintained by Coordination of Rare Diseases at Sanford. The results of two questionnaires with a 5-point Likert scale questions regarding to patients\u27 disease onset, symptoms, and daily life were obtained from 59 participants (28 males and 31 females) between June 2018 and May 2020. Independent of the registry, 22 patients were examined at the Cure VCP Disease annual patient conference in 2019. RESULTS: In the questionnaires of the registry, fifty-three patients (90%) reported that they were with inclusion body myopathy, 17 patients (29%) with Paget\u27s disease of bone, eight patients (14%) with dementia, two patients (3%) with amyotrophic lateral sclerosis, and a patient with parkinsonism. Thirteen patients (22%) reported dysphagia and 25 patients (42%) reported dyspnea on exertion. A self-reported functional rating scale for motor function identified challenges with sit to stand (72%), walking (67%), and climbing stairs (85%). Thirty-five (59%) patients in the registry answered that their quality of life is more than good. As for the weakness pattern of the 22 patients who were evaluated at the Cure VCP Disease annual conference, 50% of patients had facial weakness, 55% had scapular winging, 68% had upper proximal weakness, 41% had upper distal weakness, 77% had lower proximal, and 64% had lower distal weakness. CONCLUSIONS: The Cure VCP Disease Patient Registry is useful for deepening the understanding of patient daily life, which would be a basis to develop appropriate clinical outcome measures. The registry data is consistent with previous studies evaluating VCP patients in the clinical setting. Patient advocacy groups are essential in developing and maintaining disease registries

(Mis)perceptions of ethnic group size and consequences for community expectations and cooperation with law enforcement

The changing composition of race and ethnic group size has been noted for Western nations over the last 15 years. Analysis of this change has linked fear of crime and attitudes toward immigrants and prejudice. Changes in ethnic composition are associated with movement of White residents out of traditionally White communities, rising ethnic tension as the ethnic mix shifts, and a heightened sense of injustice regarding the justice system. (Mis)perceptions of ethnic groups size shape attitudes toward minority groups, as well as policy, practice, and individual behavior in the context of the community. This study seeks to understand the extent of such misperceptions in the Australian context and whether misperceptions of race and ethnic composition are associated with beliefs and attitudes toward formal and informal social control. Utilizing Blalock’s racial threat hypothesis, this study analyzes whether perceived relative ethnic group size is associated with self-reported willingness to cooperate with police as a way to minimize perceived threat. Findings suggest that respondents overestimate the size of minority populations while underestimating the majority White composition and that these misperceived distortions in ethnic group size have consequences for informal and formal social control
