本研究以缅甸良乌镇(Nyaung Oo)部分高中的教师教学自我效能感和校长领导风格为主要研究对象。本研究采用定量研究和定性研究相结合的方法。研究涉及100名高中教师,分别来自于不同水平的高中。为评估校长的领导风格和教师的教学自我效能感,研究人员采用了Bass和Avolio于1994年设计的多因素领导问卷(MLQ-5X)以及Tschannen-Moran和Woolfolk Hoy于2001年开发的俄亥俄州教师效能感量表(OSTES)。定量研究结果表明,就本研究所涉高中而言,校长领导理念与教师教学自我效能感量级之间不存在关联。为补充定量研究结果、了解中学教师对校长领导风格的看法以及他们自身所秉持的教学美德,本文同时也呈现了定性研究结果。本研究建议,就针对不同情境的各项领导策略,校长应学习其应用方法,并利用相关著作及研究分析报告的所得经验,学习如何与教师建立积极的联系并进行适时调整,以促进学生成才、推动学校繁荣发展。缅甸教育部及其他教育工作者(特别是培训学校的教育工作者)可利用本研究的分析结果,以提高校长选举培训工作的效能,进而优化校长领导风格对教师教学自我效能感的影响。

The environs of Taungoo Township, Bago Region are one of the high biodiversity areas in Myanmar, locating eastern side of the high mountain ranges of Middle Yoma. The dense of every green and deciduous forest in the middle Middle Yoma were logging since 10 - 20 years ago. The birds inhabiting in that area have to refuge in suitable habitats nearby. The resent status of bird species is needed to assess the diversity of birds with the respect to distribution and seasonal variation after the construction of Yangon-Nepyitaw, Myanmar after twenty years ago. A total of 50 species of 27 genera, 22 families under nine orders were recorded. That represented 44 resident species (32 terrestrial species and 12 water bird species), and 6 species of migratory birds (1 terrestrial species and 5 water bird species). As habitat utilization, 24 bird species in paddy fields, 21 species in scattered trees, 33 species in wetland and 25 species in forest habitat types were investigated. Some species used more than one habitat types. According to the assessment of abundance categories based on the calculation of individual numbers of the birds, abundant category (3 species), common bird (1 species), frequent category (5 species), uncommon category (3 species) and rare species (28 species) were categorized. Hence, bird community was still sustainable in this area. In the aspect of conservation status, all recorded bird species were under least concern categories, according to the IUCN Redlist in the study area.

This paper examines dependencies of voice and video contents on human perception of group (or inter-destination) synchronization error in remote learning by Quality of Experience (QoE) assessment. In our assessment, we use two videos and three voices (two voices for one video and one voice for the other video). We also investigate influences of silence periods in the voices and temporal relations between the voices and videos (called the tightly-coupled and loosely-coupled contents here). The voices are spoken by a teacher according to the videos. Each subject as a student assesses the group synchronization quality by watching each lecture video and the corresponding explanation voice, and then the subject answers whether he/she perceives the group synchronization error or not. As a result, assessment results illustrate that silence periods mitigate the perception rate of the error, and we can also find that we can more easily perceive the error for tightly-coupled contents than loosely-coupled ones.

如果科学家们有效地选择科研项目并公平分配荣誉,那么科学界将因此受益。脑力分配模型可以用于研究这个问题。这个问题是由金切尔首先提出并展开研究的。然而,金切尔提出的模型做了很多假设,其中很多假设与实际情况相差甚远。我们在论文中的主要贡献包含三个部分。首先,我们对金切尔提出的模型中的参数的误差对系统的影响提出了理论解释。由于在一般情况下建模的复杂性,我们在论文中主要分析了一些包含少数的科学家和项目的特殊情况。分析的结果表明,当我们假定不精确参数的情况下,得出的解可能偏离原来的分布,并导致总的成功概率的损失。另外,我们对该模型进行了修改,研究了信用共享的开放式同行评议制度。如今随着科技论文变得越来越开放,传统的同行评议也逐渐朝着开放式同行评议系统转变。在开放式同行评议系统中,信用不仅是针对作者,还针对评审者。所以我们研究开放式评议系统中作者和评审者的关系,并详细分析了开放式同行评议系统中一些特殊情况下评审者的信用分享问题。其中,我们综合考虑了作者和审稿人的名气。最后,我们研究了不公平信用分配方式的效率问题。信用对于科学家和研究人员起着激励作用,马太效应完成的科学奖励系统是在科学研究工作中分配信用的一种复杂模式。尽管在科学中不公平信用分配方式经常发生,我们仍然坚信科技信用的分配应该和科学家的贡献或者科学项目提高社会福利的成功度和重要性成正比。我们构造了一个参数用来表示随着权重的调整而增加的社会福利,同时也分析了不同参数对于它的影响。分析结果表明,不公平信用分配方式有可能达到社会最优,但是效率可能低下。本研究根据数学模型改善了在科研中资源和信用的分配,同时为社会资源和信用等福利的分配提供一种最优的分配方法。

为制定有效的草地贪夜蛾防控措施,分别自缅甸、柬埔寨和我国云南省采集4、2和8个种群共542个草地贪夜蛾样品,基于mtCOI基因序列分析这14个种群的遗传多样性指数、遗传分化系数及基因流。结果表明,缅甸草地贪夜蛾种群的单倍型多样性指数和平均核苷酸差异数分别介于0.273~0.396和4.643~6.727之间,高于我国云南省的草地贪夜蛾种群,分别介于0.047~0.214和0.791~3.636之间;除ZT种群、LS种群和TO种群外,其它11个种群的Fu’s F均为显著正值,表明缅甸、柬埔寨和我国云南省的草地贪夜蛾种群未经历种群扩张事件;在14个种群中,LS种群与其它种群分化较明显,TK种群、MY种群、CP种群、MS种群和KY种群有效迁入个数和有效迁出个数之和较高,分别为699.41、682.50、855.76、684.56和701.31,推测这5个种群在草地贪夜蛾基因交流中起着类似"中转站"的作用。

AIM To study whether Helicobacter pylori is naturally transformable. METHODS Transformation was performed in BHI broth supplemented with horse serum and yeast extract. Genomic DNA extracted from a metronidazole resistant H. pylori strain was added to H. pylori broth culture. The mixture was incubated at microaerophilic atmosphere. The DNA treated cells were plated on blood agar containing 8mg/L metronidazole to select for transformants. Sterile distilled water was used as a negative DNA control. The DNA profiles of transformants were compared with that of their parent strains by randomly amplified polymorphic DNA (RAPD) fingerprinting. RESULTS Transformation of H. pylori with DNA from a metronidazole resistant strain as a marker was demonstrated. Out of the 12 strains of H. pylori tested, 9 (75%) strains were found to be transformable. The transformation frequencies ranged from 3 4×10 -6 to 2 4×10 -4 . By RAPD, DNA fingerprints of the transformants and their parent strains showed no change in DNA profiles though transformants were all resistant to metronidazole as compared with their metronidazole sensitive parent strains. CONCLUSION Helicobacter pylori is naturally transformable which might be one of the ways that H. pylori develops resistance to metronidazole.

Background: The recent surge in economic development in Myanmar will also contribute to accelerating the health burden shift from acute infectious to chronic non-communicable diseases (NCDs) across the country. With just 11 years to achieve its goal of universal health coverage by the year 2030, significant efforts will be needed to quantify the scale of the burden facing decision-makers about health system strengthening and redevelopment. Convergence of the health systems will be an additional challenge in Myanmar. Methods: Results from a WHO study in 2009 and 2014, combined with data from the 2016 Global Burden of Disease Study, were compiled and analysed for Myanmar to assess the levels and trends of selected NCDs and NCD risk factors. Results: The prevalence of major NCDs in Myanmar are in general higher than global and regional averages, with a significant increase in diabetes mellitus and chronic obstructive pulmonary diseases in the last 25 years. Major NCD risk factors in Myanmar include smoking, use of smokeless tobacco, alcohol consumption among men, low level of fruit and vegetable consumption, hypertension, and emerging of overweight and obesity, especially among women. Tobacco use increased in both sexes between 2009 and 2014, but only significantly in men. Rates of hypertension increased for both men and women, including those currently on medications—suggesting a need for better treatment regimens. Overweight and obesity rates increased in both men and women, although the increase in obesity for men was not significant. Alcohol consumption results were mixed—with lower levels of high level drinking in men, but generally increased consumption by women. Intake of fruit and vegetables increased slightly between 2009 and 2014 and rates of high levels of physical activity also increased. Diabetes prevalence rates increased significantly in women (X2 = 11.3;p = 0.01) and men (X2 = 9.6;p = 0.02) between 2009 and 2014. Conclusions: Improved awareness of risk

中国在仅仅三十年之内转变为世界第二大经济体及世界最大出口国,人民币的使用率越来越普遍,也逐渐国际化。因此,关于汇率波动及传递对于国内物价水平和通货膨胀上的影响成为了一个值得探讨的主题。本文使用了2016年1月至2020年11月的月度数据,共59个样本;且采用向量自回归模型（VAR模型）来检视汇率对国内通货膨胀的传递效应,并发现了:（1）汇率对通货膨胀的传递存在一定的滞后性;（2）汇率波动与通货膨胀之间存在反对比关系;（3）汇率的传递是不完全的。
