Maps that provide pragmatic geographic and location information can also be used to document and describe fictional places. Readers have used the affordances of Google Maps to add settings from favorite books to this online information resource, demonstrating a complex form of reader response that I call readerly cartography. This practice aligns with an interdisciplinary scholarship on maps as culturally constructed texts. The effect of readerly cartography is to document and collocate communities of actual readers. KEYWORDS: literary mapping, reader response, reading culture, digital culture, digital humanities, There is a long tradition of mapping imagined worlds. Seen in the frontispieces and endpapers of books, this permutation of mapping a constructed world rather than the world around us [...]

[Objective] To study the difference of amino acid composition of Eriocheir sinensis from different habitats (Yangcheng Lake, Taihu Lake, Hongze Lake and Gucheng Lake) in Jiangsu and Zhejiang provinces. With advanced chemometrics analysis, an amino acid map database for identifying Eriocheir sinensis from different habitats was established. [Method] The sample was hydrolyzed by hydrochloric acid, purified and then determined the amino acid composition in the sample by amino acid analyzer. ChemPattern software was used to make chemometric analysis on amino acid profiles of Eriocheir sinensis from different habitats, and a recognition model was established. [Result] The amino acid composition of Eriocheir sinensis in Yangcheng Lake, Taihu Lake, Hongze Lake and Gucheng Lake was significantly different. We established a sample classification and identification model to accurately identify Eriocheir sinensis from different habitats. [Conclusion] The identification system of Eriocheir sinensis from different habitats (Yangcheng Lake, Taihu Lake, Hongze Lake and Gucheng Lake) established in this paper has the advantages of simplicity, stability, accuracy and good reproducibility. It could provide a scientific scheme for the origin discrimination of Eriocheir sinensis in Jiangsu and Zhejiang provinces. [ABSTRACT FROM AUTHOR]

Abstract A dynamic nonline-of-sight (NLOS) angle discrimination method is proposed to address the insufficiency of current research on the NLOS error characteristics of ultrawideband (UWB) signals in dynamic environments as well as the problem that UWB signals frequently suffer from occlusion, leading to poor or impossible localization. The experimental results indicate that the degree of UWB signal occlusion increases as the horizontal angle decreases, and when the horizontal angle is less than 167°, the UWB ranging error is so large that no ranging value is available. On this basis, a tightly integrated UWB/MEMS IMU positioning algorithm incorporating NLOS angle discrimination and map constraints is proposed; it employs horizontal angles to discriminate UWB ranging values in NLOS environments in accordance with the dynamic NLOS characteristics of UWB signals to assign better weights to UWB observations. Through comparative analysis of the results from both groups of experiments, the algorithm achieved northward, eastward, and planar positioning errors of 0.189 m and 0.126 m, 0.119 m and 0.134 m, 0.243 m and 0.211 m, respectively. Compared to the Robust Adaptive Kalman Filtering algorithm, the positional accuracy in the plane improved by 22.9% and 28.5%, respectively.

Critically conscious care theories provide a framework for teacher candidates to name, analyze, and challenge structural injustice within and beyond the classroom during their teacher education. To support teacher candidates' enactment of such a critically conscious praxis in the postpandemic era, teacher educators must understand how teacher candidates during the COVID-19 pandemic adopted, appropriated, or resisted discourses of care that may enable or limit how they become critically caring teachers. This study examines how three elementary teacher candidates during the COVID-19 pandemic (co)constructed and (re) negotiated their identities as critically caring teachers through collaborative and individual body mapping exercises during online asynchronous coursework in the southeastern United States. The way that the participants drew and narrated their mapped bodies shows that participants positioned themselves in multiple, evolving, and sometimes conflicting ways in relation to the discourses of care across their education and work contexts and professional relationships. This study contributes to teacher education scholarship by shedding light on the affordances and challenges that discursive and semiotic tools like body mapping pose for teacher educators, who need to scaffold teacher candidates' understanding of care and rehearse pedagogical possibilities during emerging crises like the COVID-19 pandemic., Introduction The way that teachers practice care affects their students' academic performance and affects their students' trust in them (Noddings, 2012). For teachers to reach their full potential as caring [...]
