Purpose: To evaluate teacher knowledge and perceptions of the development and management of stuttering, as well as bullying. Method: A 32‐item web‐based survey was created to address the purposes of this investigation. Participants were recruited in 5 states representing diverse geographic regions by sending an e‐mail with an attached information letter and an embedded e‐mail link. A total of 84 teachers completed the survey. Results: Teachers demonstrated a general understanding of the cause and characteristics associated with stuttering; however, teachers indicated some feelings of discomfort surrounding stuttering and there were some indications that they are not clear on the best ways to manage it, nor do they have access to materials. The majority identified bullying as a problem at their schools and encountered bullying of children who stutter. Conclusions: The results from this investigation were mixed in that teachers demonstrated insight into some areas of stuttering and bullying, but decreased awareness or misperceptions in others. The findings highlight the critical role of the speech‐language pathologist in the continued need for in‐services and information provision on the nature and management of childhood stuttering as well as bullying.

Insight Into

This article analyses the growing participation of UK Christians in climate initiatives over the last five years. In many cases, climate science is cited as a necessary consideration for the fulfilment of already-existing Christian commitments. This represents a significant shift in the ways UK Christians understand the role of dialogue between theology and the sciences; previous science and theology dialogue has usually been treated as an area of expert concern, primarily offering insight into apologetics or specific ethical problems. By contrast, the dialogue between climate science and theology has seen the emergence of non-technical leadership amid the expectation that climate science plays a critical role in re-examining the meaning of Christian life, both for individuals and as communities.

This study describes the design of a real-time interactive multimedia teleradiology system and assesses how the system is used by referring physicians in point-of-care situations and supports or hinders aspects of physician-radiologist interaction. We developed a real-time multimedia teleradiology management system that automates the transfer of images and radiologists’ reports and surveyed physicians to triangulate the findings and to verify the realism and results of the experiment. The web-based survey was delivered to 150 physicians from a range of specialties. The survey was completed by 72% of physicians. Data showed a correlation between rich interactivity, satisfaction, and effectiveness. The results of our experiments suggest that real-time multimedia teleradiology systems are valued by referring physicians and may have the potential for enhancing their practice and improving patient care and highlight the critical role of multimedia technologies to provide real-time multimode interactivity in current medical care.

AbstractHypoosmotic conditions activate volume-regulated anion channels in vertebrate cells. These channels are formed by leucine-rich repeat-containing protein 8 (LRRC8) family members and contain LRRC8A in homo- or hetero-hexameric assemblies. Here we present single-particle cryo-electron microscopy structures of LRRC8A in complex with the inhibitor DCPIB reconstituted in lipid nanodiscs. DCPIB plugs the channel like a cork in a bottle - binding in the extracellular selectivity filter and sterically occluding ion conduction. Constricted and expanded structures reveal coupled dilation of cytoplasmic LRRs and the channel pore, suggesting a mechanism for channel gating by internal stimuli. Conformational and symmetry differences between LRRC8A structures determined in detergent micelles and lipid bilayers related to reorganization of intersubunit lipid binding sites demonstrate a critical role for the membrane in determining channel structure. These results provide insight into LRRC8 gating and inhibition and the role of lipids in the structure of an ionic-strength sensing ion channel.

In a curriculum system, instructional materials and their enactment impacts students learning of school mathematics. In this chapter, the authors re-examine enacted curriculum in light of research on Digital Instructional Materials (DIMs) and the critical role of the mathematics teacher. This chapter documents research from two different studies suggesting that, while effectively leveraging digital materials may require teachers to think outside of their traditional views of how mathematics content is learned and communicated, doing so requires more than the resources themselves. In order to seize upon the potential for DIMs to support student learning in mathematics, teacher preparation must offer opportunities for teachers to develop and transform their technological pedagogical content knowledge (TPACK) knowledge for and with DIMs. To this end, the authors propose specific recommendations for teacher preparation programs in the digital age.

Preperformance routines are microlevel performance processes utilized by athletes to facilitate the attainment of an optimal state and enhance the chance for successful performance. Despite continued examination of these routines, only a small proportion of research has been directed toward the cognitive component of these routines. This study explored the cognitive component of elite high jumpers’ preperformance routines, and specifically the consistency of the cognitive content (i.e., psychological skills and strategies). Data were acquired over an 8-week high-jump season and subjected to inductive thematic analysis. Results revealed the consistent implementation of the cognitive content (e.g., visualization) but an inconsistent design of this content (i.e., the content of the visualization). Furthermore, results underline the critical role of high-jump coaches and an athlete’s need to be adaptable and competent in utilizing various types of preperformance routine. This study offers valuable insight into the complexities and inconsistencies of the cognitive component of high jumpers’ preperformance routines.

Insight Into

The 90S preribosome is a large, early assembly intermediate of small ribosomal subunits that undergoes structural changes to give a pre-40S ribosome. Here, we gained insight into this transition by determining cryo–electron microscopy structures of Saccharomyces cerevisiae intermediates in the path from the 90S to the pre-40S. The full transition is blocked by deletion of RNA helicase Dhr1. A series of structural snapshots revealed that the excised 5′ external transcribed spacer (5′ ETS) is degraded within 90S, driving stepwise disassembly of assembly factors and ribosome maturation. The nuclear exosome, an RNA degradation machine, docks on the 90S through helicase Mtr4 and is primed to digest the 3′ end of the 5′ ETS. The structures resolved between 3.2- and 8.6-angstrom resolution reveal key intermediates and the critical role of 5′ ETS degradation in 90S progression.

The historical background for the development of the local mode approach is reviewed, including the critical role of the radiation field. The harmonically coupled anharmonic oscillator model is described. Local modes have been used in the interpretation of XH stretching overtone spectra. These spectra can be used as sensitive probes of molecular properties such as bond length and molecular conformation. Examples of these spectral features are discussed. An intensity theory has been developed that permits the accurate calculation of relative and absolute overtone intensities. In molecules with low barriers to methyl rotation, torsional states contribute to the XH stretching band profile. A successful theoretical approach is presented that accounts for these effects and provides insight into the vibrational dynamics. The application of calculated local mode overtone spectra to atmospheric chemistry is discussed.Key words: local mode, overtone, vibrational intensity.

Autophagy fights against harmful stimuli and degrades cytosolic macromolecules, organelles, and intracellular pathogens. Autophagy dysfunction is associated with many diseases, including infectious and inflammatory diseases. Recent studies have identified the critical role of the NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasomes activation in the innate immune system, which mediates the secretion of proinflammatory cytokines IL-1β/IL-18 and cleaves Gasdermin D to induce pyroptosis in response to pathogenic and sterile stimuli. Accumulating evidence has highlighted the crosstalk between autophagy and NLRP3 inflammasome in multifaceted ways to influence host defense and inflammation. However, the underlying mechanisms require further clarification. Histone deacetylase 6 (HDAC6) is a class IIb deacetylase among the 18 mammalian HDACs, which mainly localizes in the cytoplasm. It is involved in two functional deacetylase domains and a ubiquitin-binding zinc finger domain (ZnF-BUZ). Due to its unique structure, HDAC6 regulates various physiological processes, including autophagy and NLRP3 inflammasome, and may play a role in the crosstalk between them. In this review, we provide insight into the mechanisms by which HDAC6 regulates autophagy and NLRP3 inflammasome and we explored the possibility and challenges of HDAC6 in the crosstalk between autophagy and NLRP3 inflammasome. Finally, we discuss HDAC6 inhibitors as a potential therapeutic approach targeting either autophagy or NLRP3 inflammasome as an anti-inflammatory strategy, although further clarification is required regarding their crosstalk.
