The World Health Organisation has emphasised that misinformationspreading rapidly through social mediaposes a serious threat to the COVID-19 response. Drawing from theories of health perception and cognitive load, we develop and test a research model hypothesising why people share unverified COVID-19 information through social media. Our findings suggest a person's trust in online information and perceived information overload are strong predictors of unverified information sharing. Furthermore, these factors, along with a person's perceived COVID-19 severity and vulnerability influence cyberchondria. Females were significantly more likely to suffer from cyberchondria, with males more likely to share news without verifying its reliability. Our findings suggest that to mitigate the spread of COVID-19 misinformation and cyberchondria, measures should be taken to enhance a healthy scepticism of health news while simultaneously guarding against information overload.

The objective of this research is to explore the existing mobile applications developed for the COVID-19 pandemic. To obtain this research objective, firstly the related applications were selected through the systematic search technique in the popular application stores. Secondly, data related to the app objectives, functionalities provided by the app, user ratings, and user reviews were extracted. Thirdly, the extracted data were analyzed through the affinity diagram, noticing-collecting-thinking, and descriptive analysis. As outcomes, the review provides a state-of-the-art view of mobile apps developed for COVID-19 by revealing nine functionalities or features. It revealed ten factors related to information systems design characteristics that can guide future app design. The review outcome highlights the need for new development and further refinement of the existing applications considering not only the revealed objectives and their associated functionalities, but also revealed design characteristics such as reliability, performance, usefulness, supportive, security, privacy, flexibility, responsiveness, ease of use, and cultural sensitivity.

Background: Lack of usability can be a major barrier for the rapid adoption of mobile services. Therefore, the purpose of this paper is to investigate the usability of Mobile Health applications in Bangladesh. Method: We followed a 3-stage approach in our research. First, we conducted a keyword-based application search in the popular app stores. We followed the affinity diagram approach and clustered the found applications into nine groups. Second, we randomly selected four apps from each group (36 apps in total) and conducted a heuristic evaluation. Finally, we selected the highest downloaded app from each group and conducted user studies with 30 participants. Results: We found 61% usability problems are catastrophe or major in nature from heuristic inspection. The most (21%) violated heuristic is aesthetic and minimalist design. The user studies revealed low System Usability Scale (SUS) scores for those apps that had a high number of usability problems based on the heuristic evaluation. Thus, the results of heuristic evaluation and user studies complement each other. Conclusion: Overall, the findings suggest that the usability of the mobile health apps in Bangladesh is not satisfactory in general and could be a potential barrier for wider adoption of mobile health services.

In the present study, five Black Bengal goats (Capra hircus) were used to investigate the bones of fore limb during January to June 2006. It was observed topographically that the scapula was more or less similar to other ruminant animal topographically with exception that, the presence of very short coracoid process, more or less oval shaped glenoid cavity and more extensive subscapular fossa. The humerus of adult Black Bengal goat was 12.06 ± 0.27cm in length. The diameter of shaft at the level of nutrient foramen was 4.24 ± 0.05 cm. The breadth of humerus was 1.66 ± 0.06 cm. The deltoid tuberosity was less prominent and there was shallow radial and olecranon fossa. The radius of adult Black Bengal goat was 11.12 ± 0.23 cm in length. The diameter of shaft of radius-ulna just below the interosseous space was 3.86 ± 0.12cm. The total length of ulna of adult Black Bengal goat was 14.20 ± 0.20 cm. The interosseous space was found very narrow in the present study. Six carpal bones arranged in two rows, four in proximally and two in distally were found in Black Bengal goat. Two fully developed digits were found in Black Bengal goat. Each digit had three phalanges. The total length of proximal phalanx of adult Black Bengal goat was 2.88 ± 0.08 cm, in the middle phalanx it was 1.88 ± 0.03 cm and in distal phalanx the length was2.56 ± 0.05 cm. In conclusion the present data suggest that, the anatomy of the bones of fore limbs of Black Bengal goat was differed slightly, both structurally and morphometrically with other ruminants and varied widely with non-ruminant animals.
