基于分层构权主成分分析的皖北地下水水质评价研究

针对皖北地下水水质评价,以水文地质调查数据以及取样分析结果为依据,在主成分分析的基础上,构造分层构权主成分分析评价法,并借助Arc GIS描述地下水水质区域差异性。结果表明:分层构权主成分分析方法较传统主成分分析法更具有针对性和区分度,特别针对F-含量高的地下水,可靠性和准确度更高。针对皖北地区地下水水质,东部整体优于西部,其中泗县-灵璧-宿州-雌溪一带地下水水质较好,符合饮用水卫生标准;颍上-阜南-阜阳-临泉-界首-太和一带和砀山-淮北一带属于高氟地下水区域,应采取适宜的降氟措施方可作为饮用水水源,而固镇、蒙城地区地下水受TDS、Cl-和TH含量影响,地下水水质较差,不宜作为饮用水水源。     

论北曲对魏良辅改良昆腔之影响

治曲者向从南曲层面考察魏良辅的昆腔改良,而对北曲对改良之影响关注不够。本文由魏良辅习唱北曲的经历出发,对比探析了北曲与魏良辅改良之昆腔在曲律、曲唱、曲论的共同点,指出北曲从分宫别调、考究字声、曲唱技法和经验、协调弦管等四个方面,对改良产生了具体的影响,而融北入南正是促成昆腔质变的重要因素之一。     

Shared future – shared values? Taking stock of the peace process in Northern Ireland: teenagers’ perspectives

ABSTRACT

Although preceded by years of political and policy developments, the signing of the Good Friday Agreement (or Belfast Agreement) in 1998 is generally regarded as marking the end of conflict and the beginning of the transition to peace. However, this transition has been neither linear nor straightforward. Divisions, both physical and symbolic, reflecting collective identities and ‘otherness’, remain resistant to change and continue to foster sectarianism, mistrust and outbreaks of violence. Despite some positive change, not least of which is the absence of sustained violence, the majority of neighbourhoods and schools remain either Protestant or Catholic. Drawing on data from the Young Life and Times (YLT) survey, an annual attitudinal survey of 16-year-olds in Northern Ireland that has been running since 2003, this article explores what young people's perspectives reveal about the complexities and the challenges involved in transitioning to a more shared society. Where relevant and possible, their attitudes are compared with those expressed by adults in the annual Northern Ireland Life and Times (NILT) survey. A primary focus on tracking teenagers' attitudes is important for a number of reasons. While often regarded as a ‘post-conflict’ generation, segregation and polarisation remain features of teenagers' everyday lives and the political landscape. Children and young people are one of the four key strategic priorities in the latest government strategies to build united communities and achieve change and are embedded in the Programme for Government 2016–2021. If these government commitments are to be realised, the voices of young people must become central rather than peripheral. It is important, therefore, that their opinions are not only sought, but also interrogated and fed into policy.     

The development of pattern recognition ability in children

Pattern recognition development was studied in high and low ability preschool, kindergarten, and first-grade youngsters. Pattern recognition was assessed by the administration of 96 pattern tasks which measured the ability of a youngster to find: (a) duplicate patterns and elements to a model; (b) the opposite pattern to a model; and (c) duplicate patterns but different elements than in the model. Aside from main effects for grade level, ability level, and pattern task, a significant three-way interaction was noted. This interaction was analyzed in terms of its component simple effects. The implication of these simple interaction effects for Piagetian theory and educational practice were discussed.

魏晋时期武职官受鄙夷原因初探

魏晋南朝的武职官，官位较高，在朝中的班次较前。地方武职官，较之民政官，品秩更高，职权更大。所以武职官政治地位较高。由于政治地位占优，经济地位也占优。但魏晋南朝人们对武职官则是轻视与鄙薄。这不在于武职官的地位，而主要关乎人们的观念。这些观念与士族的文化条件有关，也与这一时期的清浊观念有关，还与个人好尚有关。实际上，士族也离不开军功，武力。     

从《颜氏家训》看南北朝时期的某些世风

《颜氏家训》素以专著家训之祖而著名,因此人们往往从教育学的角度对之予以研究,从而忽视了它具有考世之资的文献学价值的一面。从文献学的角度出发对《颜氏家训》一书中反映南北朝时期学习风尚、士大夫风尚及其它风尚的材料进行研究,可以窥见当时在这些方面的世风。     

从语言看金庸如何塑造韦小宝

金庸塑造的众多小说人物形象中,《鹿鼎记》里的韦小宝无疑是最成功的一个,也是最复杂的一个。在韦小宝身上,可以看到我们许多人的影子,但他更是一个特立独行的、实实在在的人。拟从韦氏语言的特色来分析韦小宝的性格特征,进而管窥中国俗文化。     

略谈南北朝宦官的军事表现

南朝宦官的品秩要比北朝低得多,这就决定了南朝宦官的政治地位和社会地位远远不能和北朝宦官相比。南朝宦官在军事方面的表现,多为个别偶然现象,北朝宦官的军事职务往往是与刺史、郡守等地方官联系在一起的。北朝宦官的军事职位的品秩比较高,都在四品以上,这样品秩的军事职务,加重了宦官的社会政治身份,同时也使宦官拥有军权,进而为影响北魏的政治生活提供了必要的军事因素。
