高校BBS活跃用户信息行为分析

高校BBS中的活跃用户发帖量大,而且都积极回复他人的帖子。根据所发主题帖数和获得回帖数的不同,可将活跃用户分为领袖型、实力型、热情型和回应型4类。活跃用户的点入度和点出度呈显著正相关关系,活跃用户的回帖数和获回复数显著正相关,活跃用户所发主题帖数与他们回复的主题帖数也显著正相关。     

基于地域识别的城市定位及发展模式——广东省徐闻县的实证分析

城市定位是城市发展和竞争战略的核心,发展模式是城市定位的体现和多元化的发展路径,二者通过“自构”和“被构”相互作用,推动城市发展螺旋提升,城市定位与发展模式的科学准确凸显重要。地域识别是城市定位的科学依据和逻辑起点,以其为视角分析徐闻自然地域特征与发展态势,徐闻发展现状呈现典型“十字哑铃”态势,处于发展“洼地”,应以琼州海峡为切入点和突破口,体现两岸地脉相连、文脉相近、血脉相通、经济相关、发展相促的特点。从地理学综合、系统、区域差异的视角,构建圈层扇面分析模型,科学梳理徐闻县的城市定位和发展模式。研究表明：①从国际、国家、省域和区域圈层,以及环北部湾经济圈、南海北部海洋经济区、雷州半岛和海口扇面,进行圈层扇面分析,徐闻城市战略定位可以概括为,国际海峡城市,国家生态城市,滨海生态型城市、休闲宜居城市,临港工业城市、海洋经济特色城市,港口物流城市、海峡北岸旅游城市;②产业定位应结合战略定位和资源禀赋,重点发展旅游业、蓝色经济和现代农业;③相应的主要发展模式有生态旅游与海峡联动发展模式、蓝色经济与港城互动发展模式和现代农业与休闲观光一体化发展模式三种。     

Electrophoretic separation of neurotransmitters on a polystyrene nano-sphere∕polystyrene sulphonate coated poly(dimethylsiloxane) microchannel

In this paper, a poly(dimethylsiloxane) microchip with amperometric detector was developed for the electrophoretic separation and determination of neurotransmitters. For increasing the separation efficiency, the microchannel is modified by polystyrene sulphonate∕polystyrene nano-sphere self-assembly coating. A stable electro-osmotic flow (EOF) and higher separation efficiency are obtained in proposed modified microchannel. Under optimized conditions, dopamine, epinephrine, catechol, and serotonin are acceptably baseline separated in this 3.5 cm length separation channel with the theoretical plate number from 4.6?×?10(4) to 2.1?×?10(5) per meter and resolution from 1.29 to 12.5. The practicability of proposed microchip is validated by the recovery test with cerebrospinal fluid as real sample which resulted from 91.7% to 106.5%.

Muscle dysmorphia, gender role stress, and sociocultural influences: an exploratory study

Our study explored the contribution of gender role stress (GRS) and sociocultural appearance demands to symptoms of muscle dysmorphia (MD) in a college sample of 219 women and 154 men. For women, five GRS subscales, sociocultural appearance demands, age, and frequency of aerobic exercise predicted MD symptoms (model R2 = .33; F(8,210) = 12.81, p < . 001); for men, only one GRS subscale, age, and sociocultural appearance demands predicted MD symptoms (model R2 = .40; F(3,150) = 9.52, p < .001). Post hoc analyses revealed that a small number of items explained a substantial portion of the variation, suggesting that MD may be more related to specific perceptions of pressure to attain an attractive body than to global gender role stress.     

考古出土构件文化价值呈现的艺术手法——以千年古城严州府保护工程为例

突破传统将考古出土构件陈列在博物馆的做法,让构件走出展馆,将历史文脉渗透进室外的街巷细景,游客和市民在移步换景中充分感受古城的文化底蕴和魅力.以千年古城严州府综合保护工程为例,基于类型学方法应用于考古构件分类评价,深入研究考古出土构件在街巷景观、牌坊复建、室外展陈、新技术应用中文化价值呈现的艺术手法,阐述这一创新手法及其所实现的"让历史说话,让文物说话,让文化说话"良好效果,让文物的生命以另一种形式得以延续.     

顶管工程润滑泥浆性质研究

顶管机在顶进过程中受到管节与土之间的摩擦力,泥浆性质直接影响管节表面的摩擦力.本文通过调整泥浆液中膨润土及增稠剂的掺量,采用流变仪分析计算了宾汉方程与幂律方程的4个参数及漏斗粘度.结果 表明:当膨润土的掺量在8％～12％时,泥浆的流变性能较为适合;膨润土和CMC含量增加,泥浆变浓稠内摩擦增大,易形成网状结构,因此动切力增大,尤其当膨润土和CMC掺量在较高水平时,这一现象更为显著;流性指数随膨润土含量增高而降低;稠度系数会随膨润土含量提升而增大;膨润土及CMC掺量增加会使漏斗粘度上升.     

地方本科高校强化职业技术教育的发展趋势——以黔中经济区为例

随着经济社会发展和高等教育已进入大众化的实际,贵州地方本科高校人才培养与黔中经济区对高层次技能型人才需求之间产生了较大错位,已成为制约区域经济发展的重要因素。地方本科高校强化职业技术教育是高等教育服务经济社会发展的客观趋势。地方本科高校应通过创新人才培养模式、加强＂三师型＂专业教师队伍建设、促进产学研合作等方式强化职业技术教育,构建本科高校与地方经济社会协调发展的良性互动机制。
