商业促成话术的会话含义推导及其说服力分析

从语言本质上看商业促成话术产生了促进购买决定的会话含义,并顺应了消费者的购买心理,有助于提高交易成交率。在解读合作原则、语言顺应论基础上,理解商业促成话术是语言理论在社会生活中的实际运用;用合作原则的违反来推导会话含义并用语言顺应理论来分析商业话术,解释其语言理论和实践价值。     

新乡市四区六县土壤田间持水量抽样调查

对新乡市四区六县（凤泉区、红旗区、卫滨区、牧野区、获嘉县、原阳县、封丘县、延津县、新乡县、长垣县）的各种土壤类型田间持水量抽样调查结果表明：1.不同质地土壤的耕层（0～20 cm）田间持水量不同,砂土田间持水量范围8.45%～11.30%;壤土田间持水量范围11.49%～26.90%;粘土田间持水量范围24.83%～32.53%;2.相同质地土壤不同层次的田间持水量也不尽相同,砂土20～40cm土层的田间持水量7.23%～9.57%,40～60 cm土层的田间持水量9.88%～10.71%;壤土0～20 cm土层的田间持水量14.84%～25.78%,40～60 cm土层的田间持水量11.49%～26.90%;粘土20～40 cm土层的田间持水量24.83%～27.80%,40～60 cm土层的田间持水量32.16%～33.12%.     

新乡市人民公园景观分析与评价

以新乡市人民公园景观照片为样本,应用风景质量评价法中的心理物理学派的SD法对公园的景观资源进行量化评价;并借助SPSS17.0分析软件,运用因子分析法对量化数据进行分析,得出了人民公园景观视觉效果的评价结构.研究结果表明：公园美感突出,景观资源丰富,植被覆盖率和自然化程度高,但空间层次感差,色彩变化度单一.研究结果对新乡市人民公园今后的改造与建设有一定的借鉴意义.     

谈话语体中“你比如说”的话语功能探析

谈话语体中语用标记＂你比如说＂具有语篇组织功能和交际互动功能。其语篇组织功能主要由＂比如说＂来实现,首先体现为用作举例标记,后来发展为两个方向：第一,举例标记兼话题标记;第二,假设标记。其交际互动功能主要由＂你＂来承担。＂你比如说＂是谈话中发话者采取两种积极的言语策略而形成的话语功能的组合,是谈话语体中一个凝固化的习语。     

美国、俄罗斯和我国台湾地区短期高教学生培养模式比较及启示

大力发展短期高等教育已成为国际高等教育改革和发展的共同趋势.各国短期高等教育虽各有特色,但均有规律可循.通过对短期高等教育学生培养目标与计划、入学要求与学习期限、课程设置与学业要求、考核要求与学位授予等进行比较研究,总结出有益经验,针对大陆高职高专学生培养存在的问题,提出今后改革的方向是:培养目标需明确定位;课程设置需突出职业能力培养;考核要求需注重实践教学环节;学习期限需调整以适应社会多样化需求和学生个性化成长等建议.     

幼儿的入园焦虑及其影响因素

梯度入园模式能够在一定程度上缓解幼儿的入园焦虑,但幼儿个体差异较显著,尤其表现在入园第一周与家长分离时。本研究以118名新入园的托班幼儿为被试,探讨不同焦虑类型幼儿的分离焦虑水平以及入园前的交往水平对幼儿入园焦虑类型的影响,为缓解幼儿入园焦虑提供应对依据。结果发现:(1)各入园焦虑类型的幼儿按分离焦虑由高到低依次排列是:缠人型、狂暴型、封闭型和一般型,前三种类型幼儿的分离焦虑水平显著高于一般型幼儿。(2)幼儿与陌生成人的交往水平显著高于与同伴的交往水平,封闭型幼儿的两种交往水平均显著低于其他类型的幼儿。缓解幼儿的入园焦虑应根据不同类型幼儿的焦虑表现作不同的应对。关注入园前幼儿交往能力的培养,尤其是与同伴交往能力的培养,有助于幼儿更好地适应幼儿园生活。     

大学生印象整饰与人际信任的相关性研究

以徐州师范大学340名大学生为被试,使用Snyder的自我监控量表个人反应问卷和人际信任量表(ITS)作为研究工具,探讨大学生印象整饰与人际信任之间的关系,结果显示:1.不同性别的大学生在自我监控总分上差异不显著;2.不同年级大学生在自我监控总分上的差异不显著;3.不同生源地区大学生在自我监控总分上差异显著,来自城市的大学生自我监控总分明显高于来自农村的大学生;4.大学生印象整饰水平与人际信任水平不存在显著相关。     

FARMER: A novel approach to file access correlation mining and evaluation reference model

File semantic has proven effective in optimizing large scale distributed file system. As a consequence of the elaborate and rich I/O interfaces between upper layer applications and file systems, file system can provide useful and insightful information about semantic. Hence, file semantic mining has become an increasingly important practice in both engineering and research community. Unfortunately, it is a challenge to exploit file semantic knowledge because a variety of factors could affect this information exploration process. Even worse, the challenges are exacerbated due to the intricate interdependency between these factors, and make it difficult to fully exploit the potentially important correlation among various semantic knowledges. This article proposes a file access correlation miming and evaluation reference (FARMER) model, where file is treated as a multivariate vector space, and each item within the vector corresponds a separate factor of the given file. The selection of factor depends on the application, examples of factors are file path, creator and executing program. If one particular factor occurs in both files, its value is non-zero. It is clear that the extent of inter-file relationships can be measured based on the likeness of their factor values in the semantic vectors. Benefit from this model, FARMER represents files as structured vectors of identifiers, and basic vector operations can be leveraged to quantify file correlation between two file vectors. FARMER model leverages linear regression model to estimate the strength of the relationship between file correlation and a set of influencing factors so that the “bad knowledge” can be filtered out. To demonstrate the ability of new FARMER model, FARMER is incorporated into a real large-scale object-based storage system as a case study to dynamically infer file correlations. In addition FARMER-enabled optimize service for metadata prefetching algorithm and object data layout algorithm is implemented. Experimental results show that is FARMER-enabled prefetching algorithm is shown to reduce the metadata operations latency by approximately 30%–40% when compared to a state-of-the-art metadata prefetching algorithm and a commonly used replacement policy.
