Special Education Teachers\u27 Beliefs and Perceptions of Evidence-Based Reading Instruction

The purpose of this hermeneutic phenomenological study was to identify and uncover themes that emerged from special education teachers’ experiences, beliefs, and perceptions of evidence-based reading instruction. The theoretical framework that guided this study consisted of the epistemological theory of knowledge and Bandura’s social cognitive theory. Data collection methods included semistructured in-depth interviews, documentation analysis, and classroom observations. Data analyses involved reflecting on 13 special education teachers’ collective comments, dialogues, written documentation, and interview transcripts. Three themes emerged regarding the phenomenon of teaching reading to children with disabilities (a) Knowledge sources, (b) Environmental diversity, and (c) Organizational constraints. These essential themes reflected special education teachers’ beliefs and perceptions of evidence-based reading instruction for children with disabilities

Engaging with issues of emotionality in mathematics teacher education for social justice

This article focuses on the relationship between social justice, emotionality and mathematics teaching in the context of the education of prospective teachers of mathematics. A relational approach to social justice calls for giving attention to enacting socially-just relationships in mathematics classrooms. Emotionality and social justice in teaching mathematics variously intersect, interrelate or interweave. An intervention, usng creative action methods, with a cohort of prospective teachers addressing these issues is described to illustrate the connection between emotionality and social justice in the context of mathematics teacher education. Creative action methods involve a variety of dramatic, interactive and experiential tools that can promote personal and group engagement and embodied reflection. The intervention aimed to engage the prospective teachers with some key issues for social justice in mathematics education through dialogue about the emotionality of teaching and learning mathematics. Some of the possibilities and limits of using such methods are considered

Interleukin-22 and interleukin-22 binding protein signaling axis influences intubation status in trauma

Background: Interleukin-22 is a cytokine involved in mucosal immunity, whereas interleukin-22 binding protein is a soluble receptor that can potently block interleukin-22. The role of interleukin-22 and interleukin-22 binding protein in trauma remains unclear. This study investigates whether IL-22 levels are associated with intubation in patients with trauma. We hypothesized interleukin-22 levels would be lower in intubated patients. Methods: Plasma samples were prospectively obtained in the trauma bay at consecutive Level 1 activations from November 2021 to November 2022. Patients were categorized as having respiratory failure (intubated) or as controls (nonintubated). Two-to-one case-control matching was conducted based on age, sex, mechanism of injury, and Injury Severity Score. Plasma interleukin-22 and interleukin-22 binding protein levels were measured by enzyme-linked immunosorbent assay. Results: In total, 99 patients were matched (33 respiratory failure and 66 controls), with a median age of 41 (interquartile range, 29–61). Interleukin-22 levels were lower in the respiratory failure group (32 pg/mL vs 39 pg/mL, P = .03). Lower interleukin-22 correlated with higher Injury Severity Score (r = −0.41, P \u3c .001) and longer hospital stay (r = −0.26, P = .01). Multivariate analysis showed that lower interleukin-22 levels were independently associated with intubation (odds ratio, 0.97; 95% confidence interval, 0.95–0.99, P = .02). Conclusion: Interleukin-22 may serve as a biomarker for trauma-induced respiratory failure, with lower levels associated with greater injury severity and the need for intubation. Further studies are needed to explore its potential as a therapeutic and to better understand its role in trauma care

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

The comet Halley dust and gas environment

Quantitative descriptions of environments near the nucleus of comet P /Halley have been developed to support spacecraft and mission design for the flyby encounters in March, 1986. To summarize these models as they exist just before the encounters, we review the relevant data from prior Halley apparitions and from recent cometary research. Orbital elements, visual magnitudes, and parameter values and analysis for the nucleus, gas and dust are combined to predict Halley's position, production rates, gas and dust distributions, and electromagnetic radiation field for the current perihelion passage. The predicted numerical results have been useful for estimating likely spacecraft effects, such as impact damage and attitude perturbation. Sample applications are cited, including design of a dust shield for spacecraft structure, and threshold and dynamic range selection for flight experiments. We expect that the comet's activity may be more irregular than these smoothly varying models predict, and that comparison with the flyby data will be instructive.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43774/1/11214_2004_Article_BF00175326.pd
