对近代中国旅游史研究的回顾与反思

近年来我国近代旅游史研究取得了喜人的成绩,主要表现在国内旅游和国际旅游两个方面。其中对国内旅游的研究包括整体性、区域性等研究,国际旅游活动的研究多从境内和境外着手。至于研究中存在的不足之处,体现在研究内容、方法、理论等方面。只有在这几方面都有相当改观的前提下,该领域的研究才能达到一个较高的水平。     

海洋生物学微生物教学中研究型人才培养的探索和思考

海洋生物学是研究海洋中生命现象、过程及其规律的科学,是海洋药学专业人才培养过程中讲授的一门重要基础课程。它解释了海洋中生命体的起源、分类、形态、结构特征、进化与演替特征等。该课程培养学生对海洋生物的基础认识,是海洋药学专业课程体系的基石。我们在海洋生物学教学过程中,有意加入研究型人才培养的理念,进行了尝试。本文根据海洋生物学课程中海洋微生物教学特点,依据研究型人才培养的理念,在实践教学中尝试探究式和互动式两种教学方法,并进行归纳总结。

课堂细节描述——推进校本教研有效实施的新技术

观察大量的校本教研现场后,我们在和学校管理者和教师们的交流中发现,对校本教研的规范开展大家都持肯定态度,但同时流露出对校本教研的“质”的担忧。他们把现状归因在缺乏“专业引领”,希望通过专家的介入去改变这种局面。这的确是解决问题的一种办法,但同时也是目前校本教研     

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.     

主客观信息融合的港口综合能源系统评价指标体系

为建立绿色港口,实现港口的节能环保,对港口综合能源系统(port integrated energy system,PIES)的评价方法进行研究,提出一种主客观信息融合的PIES评价指标体系,将主观评价与数理统计模型进行结合,兼顾评价过程中的主客观因素,并采用基于马氏距离的统计检验方法对评分矩阵进行修正,实现对PIES的全面评价。通过青岛港董家口港区的调研数据,验证该方法的有效性。     

基于无人机激光点云的树障检测与砍伐树木数量估算

电力走廊的树木生长会对输电线路的安全运营造成巨大影响,精确检测出影响线路安全的树木并将其砍伐至关重要。因此,提出一种基于无人机激光点云的树障检测与砍伐树木数量估算方法。首先,对激光点云进行快速自动化处理,先后精确提取地面点、电力线点与植被点;其次,基于电力线点进行分段,并分析电力线与植被点的安全距离,进而确定树障区域的位置和范围;最后,对树障区域植被点云进行单木分割,并统计单木数量,最终实现砍伐树木数量的精准估算。研究结果表明,无人机激光点云可以实现输电通道树障的有效检测与砍伐树木数量的精确估算,总体树木砍伐数量估算精度可达92.3%,可为输电线路安全运营提供遥感技术支撑,也可为电网运维单位制订树木砍伐计划提供可靠依据。     

从涌泉寺古籍被淹看当前古籍保护工作的紧迫性

2005年涌泉寺在抢救受灾经书时采取了夹宣纸去湿、酒精去霉变、空气除湿等科学有效的抢救措施,避免了破坏性抢救的发生.涌泉寺经书普遍存在霉变、破损、虫蛀、裂口等问题,应采取建立恒温恒湿藏经库、去霉杀菌修复、制作夹板、限制开放藏经殿等措施加以保护;针对目前全国古籍保存保护现状,应制订防灾应急预案、加强古籍保护意识、发挥政府职能和社会力量.
