Reading Loss in Arabic Language During COVID-19 in the UAE and Proposed Solutions:The Perspectives of Primary-Grade Arabic Language Teachers

The COVID-19 pandemic caused significant disruptions in the field of education worldwide,including in the United Arab Emirates.Teachers and students had to adapt to remote learning and virtual classrooms,leading to various challenges in maintaining educational standards.The sudden transition to remote teaching could have a negative impact on students’reading abilities,especially in the Arabic language.To gain insight into the unique challenges encountered by Arabic language teachers in the UAE,a survey was conducted to explore their assessment of teaching quality,student-teacher interaction,and learning outcomes amidst the COVID-19 pandemic.The results of the survey revealed a significant decline of student reading abilities and identified several major issues in online Arabic language teaching.These issues included limited interaction between students and teachers,challenges in monitoring students’class participation and performance,and challenges in effectively assessing students’reading skills.The results also demonstrated some other challenges faced by Arabic language teachers,including a lack of preparedness,a lack of subscription to relevant platforms,and a lack of resources for online learning.Several solutions to these challenges are proposed,including reevaluating the balance between depth and breadth in the curriculum,integrating language skills into the curriculum more effectively,providing more comprehensive teacher professional development,implementing student grouping strategies,utilizing retired and expert teachers in specific content areas,allocating time for interventions,and improving support from both teachers and parents to ensure the quality of online learning.

Mobility and the Experiences of Loss-Gender and Identity Crisis in Doris Lessing’s The Summer before the Dark

In the 1950s,international division of labor began to expand in the context of globalization,which is illustrated by the expansion of labor division in the global Coffee industry in The Summer before the Dark.From the perspective of globalization,Lessing vividly reproduced the urban division space caused by the influence of mobility(generally referring to the horizontal flow of mobile individuals and capital)in Britain when widespread inflation and strikes happening,resulting in social polarization and a series of loss of experiences.They not only reflect the declining imperial image of Britain while the colonies successively declare independence,but also indicate the mental state of British citizens under the impact of globalization.

<i>In Vitro</i>Simulation of Tooth Mobility Resulting from Periodontal Attachment Loss

In our previous studies, we developed the normal periodontal ligament index (nPLI) and the residual periodontal ligament index (rPLI), to estimate residual periodontal ligament support for individual teeth during treatment planning for partially edentulous patients. The purpose of the current in vitro study was to analyze tooth mobility resulting from periodontal attachment loss, and to determine the application range of both nPLI and rPLI. The association of horizontal load-displacement and conditions of attachment loss was measured in triplicate for each anatomical tooth model at 10-minute intervals, using a universal tester at a crosshead speed of 0.05 mm/min, and a load of 0.1 N. The conditions of attachment loss were: (I) 0 mm (cementoenamel junction), (II) 2 mm attachment level, and (III) two-thirds, and (IV) one-half lengths of normal attachment. Except for the upper first molar, lower lateral incisor, lower first premolar, and the lower first molar, the displacement of each tooth type was increased significantly relative to Level I (P P < 0.01). The results indicated that nPLI at two-thirds of normal attachment and greater, and rPLI at less than two-thirds of normal attachment should be applied, respectively.

The RCT Approach for Cell Coverage Prediction (Ⅱ): Experiment and Early Results

We study on the implementation flow of the radio computerized tomography (RCT) prediction method. A case in real cellular mobile radio (CMR) system together with the prediction results are also presented. As shown by the results, the RCT prediction method is marked for its convenience and rapidity, as well as its relative high precision even when the prediction procedure is highly simplified. Since it is developed according to the characteristics of wireless communication environments of our country and has concurrently merits from both statistical and deterministic prediction models, the RCT prediction method is in good agreement with engineering practices in cellular mobile communication in cities at home. Optimized by combining with other techniques, further improvement could be achieved in the stability and precision of the RCT prediction method which now serves as the core part of a software tool for commercial use in CMR system analysis and optimization.

Self Recovery of Localization Loss for Indoor Mobile Robot

In order to solve the problem of localization loss that an autonomous mobile robot may encounter in indoor environment,an improved Monte Carlo localization algorithm is proposed in this paper.The algorithm can identify the state of the robot by real time monitoring of the mean weight changes of the particles and introduce more high weight particles through the divergent sampling function when the robot is in the state of localization loss.The observation model will make the particle set slowly approach to the real position of the robot and the new particles are then sampled to reach the position.The loss self recovery experiments of different algorithms under different experimental scenarios are presented in this paper.

AB030.Usability of ArtontheBrain:A visual-arts based mobile health solution to promote quality of life in older adults with low vision due to age-related macular degeneration

Background:Taking part in productive and enjoyable recreational activities has been shown improve quality of life for people of all ages and capabilities.However,vision loss can have a significant impact on participation in important leisure activities.This is especially the case for the elderly,whose lowered mobility is further impacted by vision loss.Technology can offer solutions to bridging some barriers caused by these deficits by bringing leisure activities to the user in the form of mobile applications.As such,the purpose of the present study was to evaluate the accessibility and usability of the ArtOnTheBrain application,a visual art based mobile health solution to promote brain health and well-being,by older adults with low vision due to age-related macular degeneration(AMD).Methods:There were a total of 16 participants(age range,65-93 years,M=79,10 males).All had a diagnosis of AMD with visual acuities in the better eye between 20/60 and 20/200.Additionally,all participants had accessed rehabilitation services and most had experience using a computer at home.Using an Apple iPad Air(2013),they were asked to interact with the ArtOnTheBrain website’s Learn(e.g.,Listen to artwork description)and Play(e.g.,complete a word-search game)features with either the Safari or Google Chrome Internet apps.Using the Concurrent Think Aloud method,participants were asked to continuously comment on their activities and experiences with the app and verbalize their internal monologue while being audio and video recorded.These recordings were later transcribed verbatim and analysed using qualitative description and thematic analysis.Results:Participants’behaviours and verbal feedback were divided based on whether they presented as barriers or facilitators.Beginning with barriers,these were mostly related to the accessibility of the visual aspects of the applications interface(i.e.,contrast and font size),whereby participants requested additional control over the magnification options,both for text as well as images of the artwork.The main facilitator was the audio option built into the Learn tab,which allowed participants to listen to the artwork descriptions.Facilitators also included the aesthetics of the app,the perceived boost in confidence in interacting with technology,and the educational and leisure benefits.Conclusions:Older adults with low vision are faced with a decreased ability to engage in leisure activities.The development of technologies aimed at increasing the accessibility of leisure activities for these individuals is an important step in increasing their quality of life.As such,despite some of the accessibility challenges,the majority of participants viewed ArtontheBrain positively.Identifying the barriers and facilitators to its use is an important step in the development of this application in order to optimize its accessibility for older adults with low vision.Future work to be done with this application will be to evaluate the cognitive impact of ArtontheBrain on low vision users.

高校教师自愿性流动的效应、困境与出路

高校教师合理有序流动对促进高等教育高质量发展具有重要的现实意义,然而,我国高校教师自愿性流动率长期偏低。高校教师自愿性流动是社会主义市场经济精神的内在要求,对教师具有利益最大化效应、对高校具有促进学科发展效应和“倒逼改革”效应,对国家建设具有推动人才辈出效应。高校教师自愿性流动的困境主要体现在高校教师自愿性流动意愿不足和高校阻碍教师自愿性流动两个方面。前者根源于受教师人力资本水平、学术市场需求、流动机会成本及心理成本的制约;后者根源于高校追求组织利益最大化、高校在与教师的博弈中具有优势地位及制度对高校的阻碍行为缺乏必要的硬性约束。提升高校教师自愿性流动的出路在于:教师应增强自愿性流动能力和意识;高校应消除对教师年龄和学历歧视、“不拘一格”引人才;政府应加大对教师自愿性流动权益的保障力度。
