非遗语境下传统戏台的当代传承与艺术转化

四川戏剧 2024年第4期 107-110页

作者：秦煜明程苑中央戏剧学院舞台美术系复旦大学新闻学院

传统戏台作为一种公共文化空间,是民俗节日、民间信仰、戏曲等非物质文化的实际载体。由于功能、地域的不同,传统戏台呈现出世俗性与神圣性交叠的复杂样态,但无论如何发展,都始终与民众日常生活联系紧密,并在一定程度上推动了戏曲艺术... 详细信息

传统戏台作为一种公共文化空间,是民俗节日、民间信仰、戏曲等非物质文化的实际载体。由于功能、地域的不同,传统戏台呈现出世俗性与神圣性交叠的复杂样态,但无论如何发展,都始终与民众日常生活联系紧密,并在一定程度上推动了戏曲艺术的繁荣发展。近年来,随着非遗话语的兴起,对传统戏台保护与发展的讨论日益受到人们的重视,对存续其中的建筑艺术等物质文化遗产和信仰、风俗、戏曲等非物质文化遗产的聚焦,实际上是对其中所蕴含的物质文明和精神内涵的探寻。从传统戏台自身文化特性出发,我们需要重视地方性的维系及标志性文化元素的挖掘,积极探索多种形式的传播路径与转化渠道。

目的了解山西省MSM新精神活性物质使用状况与艾滋病性病感染的相关影响因素,为MSM艾滋病精准防控提供依据。方法2022年9月至2023年10月,在山西省晋城、临汾和长治市通过面对面访谈、网络调查的形式收集MSM相关信息。采用SPSS 23.0统计软件分析数据,分别使用Pearsonχ^(2)检验和Logistic回归分析进行单因素和多因素分析。结果共收取724份有效问卷,MSM新精神活性物质使用率为27.49%(199人),HIV感染率为7.73%(56人);性病检测阳性126人(17.40%),不同性病阳性率分别为:梅毒6.49%(47人),生殖道沙眼衣原体8.43%(61人),淋球菌4.56%(33人)。校正年龄、婚姻状况、文化程度后,多因素Logistic回归分析结果显示,MSM最近6个月内发生同性商业性性行为、最近6个月内发生同性无保护性肛交、最近6个月内使用新精神活性物质、既往进行HIV检测者HIV感染风险高,文化程度为大专/本科及以上人群的HIV感染风险低;最近6个月内发生同性无保护性肛交、最近6个月内发生同性商业性性行为、使用新精神活性物质的MSM感染性病的风险高。结论山西省研究地区MSM新精神活性物质的使用率较高,是感染艾滋病性病的高风险人群,应加强该人群的艾滋病宣传教育、干预以及HIV/STD检测工作,通过MSM同伴教育来引导该人群坚持正确使用安全套从而减少高危性行为的发生。

芒果属全球约有69个种,我国主要分布有8个种。我国悠久的芒果栽培历史形成许多具有地方特色的天然杂交种。在不断与环境协调发展的过程中,芒果枝叶、果实等外观形态发生了一定的变化,其花粉在保持遗传保守性和稳定性下却形成了独特的形态特征。为了深入研究芒果属植物花粉形态的分类学意义,理清芒果天然杂交种之间的系统发育关系,本研究基于花粉微观特征,对芒果属种质开展孢粉学研究及遗传关系分析。利用扫描电镜系统观察芒果属2个种32份芒果材料的花粉外部形态和花粉外壁纹饰等形态特征,在此基础上,对花粉6个数量性状进行聚类分析。结果表明:32份芒果种质花粉均属于N3P4C5型,极面观呈3裂三角形,赤面观呈近椭圆形,萌发沟孔为3条,萌发沟孔开裂度几乎到达花粉粒的两极;各材料的花粉形状大小、萌发脊宽窄、花粉纹饰、花粉外壁网孔密度和大小均存在差异;条纹状或网状纹饰和纹孔布满花粉粒表面,大多数芒果花粉属于网状纹饰,网孔形状多样,主要是圆形和长条形,纹脊粗糙,网孔分布密度在不同材料间存在差异。根据花粉粒大小、花粉形态、萌发脊宽、网孔大小和网孔密度等数量性状对参试材料进行聚类分析,32份芒果种质在相似距离为15时可分成三大类群,来自东南亚的马切苏、暹罗芒、仁和吕宋等芒果资源在谱系图中聚为一类,显示出一定的地域特征;萌发脊较窄的云南土芒、布鲁斯和象牙芒26号聚为一类;扁桃、收集的扁桃–芒与国内常见芒果栽培种聚为一类。原始的野生种白花本地芒与扁桃1号、扁桃2号、扁桃3号、扁桃4号聚为一组,该类资源具有原始型、野生型的特点。本研究可为芒果花粉形态的分类、亲缘关系和演化研究提供孢粉学依据。

In this paper,we consider the two-dimensional(2D)Prandtl-Hartmann equations on the half plane and prove the global existence and uniqueness of solutions to 2D Prandtl-Hartmann equations by using the classical energy methods in analytic *** prove that the lifespan of the solutions to 2D Prandtl-Hartmann equations can be extended up to T_(ε)(see Theorem 2.1)when the strength of the perturbation is of the order of ε.The difficulty of solving the Prandtl-Hartmann equations in the analytic framework is the loss of x-derivative in the term vδ_(y)*** overcome this difficulty,we introduce the Gaussian weighted Poincaréinequality(see Lemma 2.3).Compared to the existence and uniqueness of solutions to the classical Prandtl equations where the monotonicity condition of the tangential velocity plays a key role,which is not needed for the 2D Prandtl-Hartmann equations in analytic ***,the existence and uniqueness of solutions to the 2D MHD boundary layer where the initial tangential magnetic field has a lower bound plays an important role,which is not needed for the 2D Prandtl-Hartmann equations in analytic framework,either.
