基于web需求的图片处理系统设计研究

随着网络技术的发展,在资料交换和信息获取的过程中,图片资料占据了越来越大的比重,然而上传前图片的处理功能相对比较单一,无法满足人们未来发展的需求,越来越多的网络用户希望在图片上传过程中,借助web页面就可以对图片进行处理和修饰。因此本文将会对web页面图片处理系统设计与研究进行介绍,以实现图片处理的人性化,提升用户工作效率。     

Lifesource XL-18 pedometer for measuring steps under controlled and free-living conditions

The primary aim was to examine the criterion and construct validity and test–retest reliability of the Lifesource XL-18 pedometer (A&D Medical, Toronto, ON, Canada) for measuring steps under controlled and free-living activities. The influence of body mass index, waist size and walking speed on the criterion validity of XL-18 was also explored. Forty adults (35–74 years) performed a 6-min walk test in the controlled condition, and the criterion validity of XL-18 was assessed by comparing it to steps counted manually. Thirty-five adults participated in the free-living condition and the construct validity of XL-18 was assessed by comparing it to Yamax SW-200 (YAMAX Health & Sports, Inc., San Antonio, TX, USA). During the controlled condition, XL-18 did not significantly differ from criterion (P > 0.05) and no systematic error was found using Bland–Altman analysis. The accuracy of XL-18 decreased with slower walking speed (P = 0.001). During the free-living condition, Bland–Altman analysis revealed that XL-18 overestimated daily steps by 327 ± 118 than Yamax (P = 0.004). However, the absolute percent error (APE) (6.5 ± 0.58%) was still within an acceptable range. XL-18 did not differ statistically between pant pockets. XL-18 is suitable for measuring steps in controlled and free-living conditions. However, caution may be required when interpreting the steps recorded under slower speeds and free-living conditions.

唐代两蕃的考古学文化研究

契丹与奚在唐代被称为两蕃,两蕃对于辽西地区的历史文明进程产生过重要影响。两者具有相同或相似的族源、驻牧范围、生业方式、文化习俗、民族关系,尤其在族源认同上及其与中原王朝及周边民族政权的关系中,两者具有共同的族源记忆和文化认同。故本文将两蕃界定为一个文化共同体,从考古学文化的角度,对两蕃的遗存进行考察与研究,并对唐代两蕃的驻牧范围、墓葬分期与分区、早期墓葬制度、文化交流及其生业方式与生态环境变迁之间的关系等问题的研究提出自己的看法。     

网络学习社区中学习者的社会行为及其影响的教学论阐释

网络学习社区是与学校教育与课堂教学相区别的另一种教育社会和教学时空,从教学社会学的视角来诠释网络社区中学习者行为的社会性及其对网络教育的影响是非常重要的研究范式。学习者通过最常见的6组基本行为建构着网络学习社区中的知识与情境,这些基本行为既是社区学习者从个体行为演绎成从众活动和学习懈怠等群体行为的基本途径,也是实现学习者之间竞争与合作交互行为、师生之间控制与服从交互行为的基本途径。上述学习者社会行为是网络中教育主体的社会关系与教学活动的主要呈现方式,设计与把握学习者的这些社会行为是网络教育绩效提升的关键,很值得网络教育管理者重视。     

南庄头遗址与白洋淀地区史前村居生活的萌芽

南庄头遗址距今约一万年,属于中国新石器时代早期遗存的重大发现,具有显著科学价值。该遗址显示出旷野型的生存环境,具有多方面生活场所要素和相对集中的人类活动空间,多元化和稳定性较强的生业经济能够支撑基本的社会发展,原始家庭手工业有一定呈现。总的来看,南庄头先民生活内容迥异于旧石器时代人类社会,与后世村居生活具有较强的连续性,展示出万年前白洋淀地区村落和定居史的萌芽状态,成为本地史前社会演进的一个重要开端。这一转变过程是人类发展和环境变化交互作用的结果。     

An explorative study of shopper-based salient e-servicescape attributes: A Means-End Chain approach

This study aims to address the gaps inherent in existing studies by exploring the salient e-servicescape attributes. Employing the Means-End Chain (MEC) approach, empirical evidence was obtained through in-depth interviews with online shoppers using laddering technique to determine the most frequently mentioned attributes from four servicescape dimensions: (1) ambient; (2) design; (3) signs, symbols and artifacts; and (4) interaction. Accordingly, we laddered three levels of online shoppers’ responses from concrete to less concrete abstractions, i.e. attributes, benefits, and end-desirable beliefs. As a result, seven salient e-servicescape attributes were identified. Each of the four dimensions suggests the attributes’ linkage to benefits and end-desirable beliefs. Specifically, the study finds quality photograph, as the salient attribute of the ambient dimension, may set the point of initial attraction and move shoppers from understanding the product to linking the web site contents. In the design dimension, navigation bar, categorization, and simple arrangement are the salient attributes. Company logo represents the most salient attribute under the signs, symbols and artifacts dimension because it not only facilitates recognition and recall of prominent web sites, it also acts as the determinant of perceived risks. In the interaction dimension, although pricing information is the salient attribute that evokes happiness and confidence among online shoppers, it may dilute their perception on web site's success. Instead, confirmation mail can possibly act as a determinant to web site's success. By offering a finer granularity of information, our findings provide insights to online sellers on the salient attributes to consider in order to effectively promote their shopping web sites to create positive emotional response and buying behavior among the online shoppers.
