Surface and Content Validity of the Mentoring Function Scale for Novice Nurses

This study aimed to examine the surface and content validity of the Mentoring Function Scale for Novice Nurses, used to assess the mentoring of entry-level nurses, and to refine the scale items. In Study 1, six nurse education researchers, selected using convenience sampling, with five or more years of nursing experience and experience teaching novice nurses, were invited to an expert meeting in July 2015. A group interview was conducted that lasted approximately 120 minutes. Study 2 examined the content validity index. Between September and November 2015, we distributed a self-administered questionnaire survey to 11 participants selected by convenience sampling. The participants included five nurse education researchers with a minimum of five years of nursing experience and experience teaching novice nurses, as well as six clinical nurses with a master’s degree or higher. Finally, 81 questionnaire items were retained from the initial 125 items. The 81-item Mentoring Function Scale for Novice Nurses had higher content validity than the original scale. To further increase the scale’s applicability, future studies should assess its reliability, construct validity, and criterion-related validity.

Monitoring Soil Salt Content Using HJ-1A Hyperspectral Data: A Case Study of Coastal Areas in Rudong County, Eastern China

Hyperspectral data are an important source for monitoring soil salt content on a large scale. However, in previous studies, barriers such as interference due to the presence of vegetation restricted the precision of mapping soil salt content. This study tested a new method for predicting soil salt content with improved precision by using Chinese hyperspectral data, Huan Jing-Hyper Spectral Imager(HJ-HSI), in the coastal area of Rudong County, Eastern China. The vegetation-covered area and coastal bare flat area were distinguished by using the normalized differential vegetation index at the band length of 705 nm(NDVI705). The soil salt content of each area was predicted by various algorithms. A Normal Soil Salt Content Response Index(NSSRI) was constructed from continuum-removed reflectance(CR-reflectance) at wavelengths of 908.95 nm and 687.41 nm to predict the soil salt content in the coastal bare flat area(NDVI705 < 0.2). The soil adjusted salinity index(SAVI) was applied to predict the soil salt content in the vegetation-covered area(NDVI705 ≥ 0.2). The results demonstrate that 1) the new method significantly improves the accuracy of soil salt content mapping(R2 = 0.6396, RMSE = 0.3591), and 2) HJ-HSI data can be used to map soil salt content precisely and are suitable for monitoring soil salt content on a large scale.

基于TEC数据的含电离层闪烁卫星导航信号模拟

电离层闪烁导致卫星导航信号在传播过程中幅度与相位发生随机波动,严重影响接收机的性能。为模拟真实的受电离层闪烁影响的卫星导航信号,以供接收机进行性能测试,提出了基于电离层总电子含量(Total Electron Content,TEC)数据的电离层闪烁仿真方法。该方法通过输入卫星观测文件与导航电文获得电离层的TEC和仰角,利用TEC数据和各卫星仰角,估计出受电离层闪烁影响的各卫星导航信号幅度闪烁指数和相位闪烁指数,结合Cornell模型实现卫星导航信号模拟。该方法充分考虑了卫星导航信号闪烁指数获取困难,以及电离层闪烁对不同卫星导航信号的影响,能够高保真反演卫星导航信号。试验结果表明,该方法反演的电离层闪烁与实际发生的闪烁具有良好的一致性。

Epistemological Attitudes Towards Sources of Knowledge Semantic Questionnaire

Given the everlasting significance of knowledge in society and academia,this article proposes a theoretical and methodological perspective on conceptualizing and investigating it.Specifically,it aims to explore the epistemological attitude(EA)theory and its semantic approach to assessing sources of knowledge.The article provides a concise overview of the EA theory,which advocates for a systemic perspective on cognition and knowledge.It introduces and elaborates on the core concept and model,which serve as the foundation for the proposed methodology.This methodology suggests examining knowledge objects through subjective,contextual,and epistemological realms as multi-level knowledge constructs.Emphasizing the importance of semantics in studying knowledge,categories,and meanings,the article proposes an epistemological attitude towards sources of knowledge semantic questionnaire.The article delves into the methodology,reflecting on its four consecutive stages.It begins with the formal and substantive stages,which involve selecting sources,choosing academic experts as target participants,and developing content.The procedural stage follows,in which an expert review approach is employed to assess the content validity of the method.Finally,the article discusses the semantic method,elucidating its structure,features,semantic categories,and assessment procedure.The proposed method provides a unique contribution by enabling the analysis of the epistemological and socio-psychological meanings of sources,representing them as semantic constructs.
