In recent years, an increasing number of data platforms have been built to facilitate historical information storage, display, management and analysis. In such a context, the geographic information system(GIS) begins to contribute to the study of Chinese history. Its contribution is highlighted in nine areas: historical climate, fluvial landforms, town economies, rural settlements, hydraulic societies, environmental changes, ancient cities, ancient maps and HGIS-enabled research methods. The application of GIS to the study of Chinese history initiates a reform in research methods and at the same time upgrades the philosophy of history studies, facilitating the utilization of a diversity of historical data(documents, ancient maps, remote-sensing images, archaeological information, etc.) for dynamic tracing and multi-factor comprehensive research. At present, restricted by traditional disciplinary boundaries, the construction of HGIS platforms remains slow and insufficient, making it difficult to extensively apply GIS to the study of Chinese history.展开更多

Methodology: A prospective, qualitative study with a phenomenological approach was carried out at the Brachytherapy unit of the National Institute of Oncology in Rabat, Morocco. Purposive sampling was used to recruit 31 patients undergoing high dose-rate brachytherapy for cervical cancer from July 2020 to August 2020. Semi-structured, one-to-one interviews were conducted by a female radiation oncologist in Arabic, guided by a theme list. The interviews were translated and a thematic analysis was performed. Results: Data saturation was achieved having interviewing 31 participants, aged 27 - 70 years. Findings on patients’ informational needs were the overarching theme and form the focus of this article. The informational needs included: providing patients with disease- and treatment-related information in their home language;adequate information concerning pre-treatment preparation, possible side-effects, and sexual intercourse;and providing patients with informative material adapted to their needs as standard procedure. Conclusion: This study has identified unmet women’s informational needs during brachytherapy for cervical cancer. Providing patients with sufficient and understandable information, adequate preparation before the procedure, more sensitive support during the procedure, and debriefing afterward could lessen feelings of fear and anxiety towards treatment delivery. Guidelines with a patient-centered approach could thus be developed to be used as a tool to assist members of multidisciplinary teams in providing quality care to this group of women.展开更多

INTRODUCTION Changbai Mountain is situated between E127°54′-128°08′, N40°58′-42°06′ about 2700 meters above sea level. It is the typical area of the mountainous climate in the monsoon area of the temperate zone on the globe. The well reserved primeval vertical distribution of natural landscape belts and the Natural Conservation of Changbai Mountains adopted by the UNESCO′s MAB Program cause the worldwide attention of geographers. Beside the complexity of the climatic structure itself, the mechanical effection of the high mountain body also effect the climate in the eastern part of China. In the mountain area where short of meteorological observation data, the climatic study by remote sensing is favorable for discovery and representation of climatic law in large area.展开更多

文摘通过健康信息传播和教育说服公众形成健康行为意愿是一个现实课题。本文以精细加工可能性模型(elabo‐ration likelihood model,ELM)为理论基础,将说服路径分为中心路径和外围路径,同时引入短期的时间纵向数据追踪。本文实施了10天左右持续使用健康信息的日记报告实验,基于30名大学生提交的377条健康信息日记数据,建立个体层面与信息线索、时间层面的多层线性回归模型(hierarchical linear modeling,HLM),探究健康信息对个体健康行为意愿的说服机制。研究结果表明,健康行为意愿的说服过程主要是信息质量和来源可信度的混合式说服路径;在7天周期内,健康信息说服效果逐渐增强,其中信息质量的说服效果更为稳定,来源可信度的说服效果则随着时间推移逐渐被抵消;健康信息说服路径随个体特征和接触时机而变;健康意识调节来源可信度和信息热度对说服效果的影响,且具有时间效应;卷入度调节信息质量和来源可信度对信息说服效果的影响,但不存在时间效应。本文的研究结果有助于深入理解健康信息对健康行为意愿改变的说服机制,为建立“以人为本”的个性化健康信息传播和健康教育方案提供了参考。
