Model construction of Chinese preservice physical education teachers’ perception of social media: A grounded theory approach

(1) Background: Pre-service physical education teachers commonly embrace social media for multiple purposes. However, little is known about their perception of social media, which could affect the appropriate use of social media in their future professional work. This study aims to explore a theoretical model of how pre-service physical education teachers perceive social media in order to provide a basis for educators to guide their appropriate use of social media. (2) Methods: Qualitative data were collected in diverse ways, mainly from interviews. Seventeen Chinese preservice physical education teachers were selected as participants by a purposive sampling technique. The interview questions focused on participants’ motivation, expectations, and experiences in social media usage. Grounded theory was used to analyze the data by ROST CM and Nvivo 12. (3) Results: The perception of social media among teachers includes three subsidiary categories made up of 10 sub-categories, 70 concepts, and 307 labels. The three categories are (a) value perception, including the perspective of intelligent function, interaction, and rich information, (b) risk perception, involving psychological risk, information risk and privacy risk and (c) overall perception, like development trends, current status and basic elements. (4) Conclusions: Chinese preservice physical education teachers perceive social media as having similarities and differences compared to other countries. Future research should consider a large sample survey to revise and verify the initial exploration of perception and study diverse groups of teachers’ perceptions of social media.</p

Dataset for: CHLORIDE INTRACELLULAR CHANNEL 1 (CLIC1) CONTRIBUTES TO MODULATION OF CYCLIC AMP-ACTIVATED WHOLE CELL CHLORIDE CURRENTS IN HUMAN BRONCHIAL EPITHELIAL CELLS

Chloride channels are known to play critical physiological roles in many cell types. Here we describe the expression of anion channels using RNA Seq in primary cultures of human Bronchial Epithelial Cells (hBECs). Chloride intracellular channel (CLIC) family members were the most abundant chloride channel transcripts, and CLIC1 showed the highest level of expression. In addition, we characterise the chloride currents in hBECs and determine how inhibition of CLIC1 via pharmacological and molecular approaches impacts these. We demonstrate that CLIC1 is able to modulate cyclic AMP-induced chloride currents and suggest that CLIC1 modulation could be important for chloride homeostasis in this cell type
