基于二元语义的企业员工满意度评价研究

针对采用语言信息量度的企业员工满意度评价问题,提出了一种将二元语义信息处理方法运用于企业员工满意度评价的方法。首先给出了企业员工满意度的评价项目,并介绍了二元语义概念及其算子,在此基础上提出了基于二元语义的企业员工满意度评价方法与处理步骤,最后通过算例验证方法的可行性和有效性。     

旅游合同中旅游营业人的界定

通说认为旅游合同是旅游者与旅游营业人之间订立的合同。在旅游合同已经成为典型合同的国家或地区对旅游合同设有诸多特别调整规则。然对于旅游营业入的资格则有诸多争议,通过从比较法的角度并结合现行法对旅游营业人进行深入的分析,以组织特质以及旅游服务为标准进行界定,并对旅游营业人进行类型化,力求在旅游合同意义上对旅游营业人进行界定。     

辛亥鼎革士子的政治选择及其对革命的认知——以云南绅耆为例

辛亥鼎革,清季士子大部分以积极的姿态融入民国,即使自况为＂遗老＂、＂遗民＂者,其身份界定亦大有讨论余地,其中曲折甚有探讨之处。以云南绅耆在鼎革之际的政治选择的过程及其对辛亥革命的认知为例,我们可以看到清朝与民国之间存在明显的延续性,民国建立的特殊方式,为清季士子接受和进入民国创造了一个更为宽松的环境。     

满足一类Hormander型条件的奇异积分算子交换子的端点估计

设T是奇异积分算子,[b,T]是它与Lipschtz函数b生成的交换子。该文讨论了核函数满足一类变形的Hrmander条件时,交换子[b,T]的端点估计,即[b,T]是从Ln/β（Rn）到BMO（Rn）有界的。     

基于Sobel算子预处理的变分水平集曲线演化目标跟踪方法

针对变分水平集在曲线演化目标跟踪方法中,直接计算得到的模值图较杂乱,利用Gaussian函数首先对图像进行平滑处理,然后利用中心差分计算梯度,并推导出二者的作用等价于Sobel算子与图像作运算.实例表明该算法使得曲线在演化过程中能够准定位,从而实现目标的正确跟踪.

利用强单调映象原理和临界点理论讨论2m阶微分方程边值问题{（-1）^m·u^（2m）（t）=f（t,u（t））,t∈[0.1] u^（2i）（0）=u^（2i）（1）=0 （i=0,1…,m-1）,其中f：[0,1]xR^1→R^1连续,得到其解的存在性和多重性．     

粗糙核向量值奇异积分算子的几个加权赋范不等式

向量值奇异积分算子的核决定着算子的性质和加权不等式．标准核向量值奇异积分算子的研究内容已经日趋完善,弱Dini型核以及粗糙核向量值奇异积分算子也有所研究,但研究内容不够完善,现继续研究粗糙核向量值奇异积分算子,得到了这类算子的几个加权赋范不等式,丰富了向量值奇异积分算子的理论．     

Schooling sexualities and gendered bodies. Experiences of LGBT students in Icelandic upper secondary schools

In this paper, we study how Lesbian, Gay, Bisexual and Transgender people (LGBT) students in Icelandic upper secondary schools interpret their experience of heteronormative environment and how they respond to it. The aim is to explore how sexualities and gendered bodies are constructed through ‘schooling’. The article draws on interview data with seven LGBT students who attended five different upper secondary schools. We also use visual data collected during fieldwork at one upper secondary school and exemplify the results with a poster and a digitalised short-film, produced by the students, to substantiate what participants told us in the interviews. All of the students experienced heteronormative discourse and lack of respect and indicated that they did not feel fully accepted in school. Upon entering the classroom, the visibility of LGBTs and discussion about different performances of gender and sexuality seem to disappear, whether in terms of textbooks, course content, teaching practices and school environment. Furthermore, LGBTs and those who do not conform to the hegemonic performances of gender are often constructed as deviations from the norm, strange, and even depicted as the abjected other. This applies in particular to the informal school, which embraces the traditions, culture and social interactions among students and teachers. This othering occurs, despite relatively positive attitudes towards LGBT people in Icelandic society in general. The results signify a gap between policy and practice as regards the positioning of LBGT students, which affects their schooling and well-being.
