Application of Situational Teaching Method in Primary Oral Teaching of Chinese as a Foreign Language

With the acceleration of our country’s internationalization process, international students from all over the world are constantly pouring into China, with different purposes to learn Chinese. In international students’ daily life, it is impossible to completely avoid using Chinese, especially spoken Chinese. However, in actual teaching, we found that many teaching methods in oral Chinese classes are either very similar to reading and writing classes, or there are too many blind activities and games, which is very detrimental to the improvement of Chinese learning and oral communication skills of international students. In recent years, the application of situational teaching method of second language teaching has attracted increasing attention. How to use situational teaching method correctly to improve students’ oral expression ability and Chinese level is particularly important

Twist angle effects on the dynamic response of in-plane-switching liquid crystal displays

Twist angle effect on the response time of in-plane-switching liquid crystal displays are analyzed. We propose a device configuration whose top and bottom boundary liquid crystal layers are symmetric to each other with respect to the electric field direction. The analytical results of this device configuration indicate that the response time is improved at least 4X faster than that of a conventional in-plane-switching twisted-nematic mode and normal in-plane-switching mode.Comment: 12 Pages, 3 Figures. will be appeared in Appl.

Silt Resource Utilization and Benefit Analysis of Silt Fired Perforated Brick Production: Take Nantong, China for Example

Resource utilization of silt dredging from rivers and other lake is an important issue that related to many government departments like water conservancy, shipping, land resources, construction management and other industries. It involves social, economic and environmental effects. With the encouragement of national policy of protecting arable land, make use of dredging silt to producing clay wall material is a higher value-added resource utilization than used for fill material and land use. Combined with the practice of producing fired perforated brick in Jiangsu Nantong, the economic, social and environmental benefits were analyzed based on the Summary of all these resource utilization. And the recommendation of regional development of the industry was presented at last. Key words: Silt; Resource utilization; Fired perforated brick; Benefit analysis; Water dredgin

Examining Factors Influencing Colorectal Cancer Screening of Rural Nebraskans Using Data from Clinics Participating in an Accountable Care Organization: A Study Protocol.

BACKGROUND: Although mortality rates of colorectal cancer (CRC) can be significantly reduced through increased screening, rural communities are still experiencing lower rates of screening compared to urban counterparts. Understanding and eliminating barriers to cancer screening will decrease cancer burden and lead to substantial gains in quality and quantity of life for rural populations. However, existing studies have shown inconsistent findings and fail to address how contextual and provider-level factors impact CRC screening in addition to individual-level factors. PURPOSE: The purpose of the study is to examine multi-level factors related to CRC screening, and providers\u27 perception of barriers and facilitators of CRC screening in rural patients cared for by accountable care organization (ACO) clinics. METHODS/DESIGN: This is a convergent mixed method design. For the quantitative component, multiple data sources, such as electronic health records (EHRs), Area Resource File (ARF), and provider survey data, will be used to examine patient-, provider-, clinic-, and county-level factors. About 21,729 rural patients aged between 50 and 75 years who visited the participating ACO clinics in the past 12 months are included in the quantitative analysis. The qualitative methods include semi-structured in-depth interviews with healthcare professionals in selected rural clinics. Both quantitative and qualitative data will be merged for result interpretation. Quantitative data identifies what factors influence CRC screening, while qualitative data explores how these factors interact with CRC screening. The study setting is 10 ACO clinics located in nine rural Nebraska counties. DISCUSSION: This will be the first study examining multi-level factors related to CRC screening in the new healthcare delivery system (i.e., ACO clinics) in rural communities. The study findings will enhance our understanding of how the ACO model, particularly in rural areas, interacts with provider- and patient-level factors influencing the CRC screening rate of rural patients

Effects of distance from home to campus on undergraduate place attachment and university experience in China

First-year students in transition from hometown to campus are generally confronted by intellectual and social challenges as well as disruption and the formation of the place attachments associated with relocation. Understanding the variables affecting student place attachment helps address the widespread concern about student transition. Interactions between place attachment to hometown and campus, and the effects of endogenous and exogenous variables on place attachments, were analysed using covariance analysis, based on questionnaire data gathered at a Chinese university. Campus identity acts as a predictor for the other three dimensions of place attachment to hometown and campus: hometown identity, hometown dependence and campus dependence. Place attachment to campus exerts a direct effect on place attachment to hometown, while the latter indirectly impacts on the former through mediators including academic self-efficacy and peer relationships. Gender, household registration record and duration of dormitory stay were also identified as statistically significant predictors of student place attachment

Reflective in-plane switching liquid crystal displays

The performance of a reflective in-plane switching (IPS) liquid crystal display is simulated by the parameter space method. The IPS electrodes and reflectors can be separately fabricated on the top and bottom substrates. The normally black reflective in-plane switching display shows wide viewing angle, high contrast ratio, weak color dispersion, and fast response time

Determining Singularity-Free Inner Workspace through Offline Conversion of Assembly Modes for a 3-RRR PPM

The existing singularity avoidance methods have deficiencies, such as the conditionality of the online conversion of the assembly modes (AMs) and the kinematically redundant manipulator with the predicament of the prototype design and added complexity of the mechanism. To address these issues, a method to determine a singularity-free inner workspace through offline conversion of the AMs of the 3-RRR planar parallel manipulator (PPM) is presented. Based on the geometric relations among rods of the manipulator during the occurrence of singularity, and the singular points at or near the boundary of the workspace are permitted, the AMs and ranges of the orientation angle of the moving platform corresponding to the inner singularity-free workspace are determined through a three-dimensional search method. The simulation and experimental comparisons indicate that singular-free paths related to the constant or variable orientation angle of the moving platform can be planned on the singularity-free inner workspace
