We develop and describe a framework for research in a particular segment of digital advertising. Internet Advertising Paid Slots and Spaces (IAPS) is a neologism and work almost like a stock exchange for buying and selling advertising in various formats on designated spaces around web and make a significant contribution to Internet advertising revenues. These paid spaces were found to encompass diverse areas of Internet advertising that include search engine marketing, social media advertising and display advertising. Given the complexity of the modern digital advertising eco system, this literature review seeks to provide clarity, up-to-date knowledge and ongoing insights into Internet advertising channels, for managers making investment decisions in this context.  相似文献

城郊乡村的乡土景观面临"重写",而其间的乡土住宅正在经历一种自发的转型,其"自组织"的生成机制值得研究。本文以科尔沁右翼前旗地区的若干村镇的当代乡土住宅为样本,从组织机制的角度,分析其受控过程,分别从基因、共享、突变和蔓延四个方面展开分析,总结该地区的当代乡土住宅从无序向有序的演变过程。  相似文献

研究表明:碱滩山东花岗闪长岩LA-ICP-MS锆石U-Pb年龄为323.6±3.2 Ma,时代为早石炭世,岩石样品SiO2含量介于66.37×10-2~69.44×10-2之间,具富钠(Na2O>K2O),弱过铝(铝饱和指数(A/CNK)介于1~1.1之间)的特征,属弱过铝钙碱性岩石系列;岩石球粒陨石标准化稀土配分曲线呈右倾斜曲线,斜率较大,属轻稀土富集型;微量元素蛛网图表明岩石明显富集Rb、Ba、Th、U、K等大离子亲石元素,亏损Nb、P、Ti等高场强元素。综合区域背景分析表明:碱滩山东花岗闪长岩具有岛弧花岗岩地球化学特征,在R1-R2图解中落入碰撞前花岗岩区,其与研究区广泛分布的晚石炭世早期石英闪长岩、花岗闪长岩、二长花岗岩、奥长花岗岩等共同构成了类似于TTG岩石组合的特征,暗示了研究区在石炭世可能处于大陆边缘弧的构造环境。  相似文献

广告是一门说服的艺术,其目的是让消费者自觉自愿地购买商品或服务,Banner(旗帜广告)当然也不例外。Banner是继传统媒体(如广播、电视节目、报刊杂志等)最为有效的宣传方式。然而,由于缺乏对Banner宣传固有特点的充分认识或存在一些认知误区,用户在Banner的设计与制作方面有时会提出一些不恰当的设计要求,这些设计往往不仅不能引起访问者的关注,更有可能大大降低了Banner推广的效果。  相似文献

The effect of internet advertising has been a controversial issue, especially on the topic of how to effectively draw more attention from internet users. According to traditional attention theory, we know people pay lesser attention on other objects if the main browsing contents occupy more of the viewer’s mental resources. Therefore, we know different information types of webpage should have different influences on users’ attention. On the other hand, an effect called ‘banner blindness’ makes viewers naturally overlook the advertising based on their previous experience. It is therefore becoming more and more difficult to increase viewer’s attention on advertisement simply by adding salient features on the advertisements. In light of this new challenge in Internet advertising, verifying the different influences of the information types on advertising attention is the main goal of this study.Great amounts of previous studies relevant to internet advertising focused on the advertisement itself, like the form, color, size and location. However, this study put focus on how the information types and the webpage structure influence the viewer’s attention on banner advertising. This research tested the effect on user attention of four common information types on Internet webpages: (1) text-based webpage; (2) text-picture mixed webpage; (3) picture-based webpage; and (4) video-based webpage. This study hopes to provide valuable information for matching advertising with viewing tasks that will stimulate the most user attention.  相似文献

准好来铜矿床位于大兴安岭南段成矿带中段,产于晚古生代弧后盆地内"双峰式"海相火山岩地层中。通过对大地构造环境、地层层序、含矿建造岩石组合及岩石化学成分等分析研究,总结了矿床地质特征,并对矿床的成因进行了探讨。结果表明,该矿床形成于晚古生代弧后盆地发育阶段的海底喷流沉积作用,与古生代活动大陆边缘成矿系统相关,属广义上的块状硫化物矿床,具有层控性、分带性等特点,其成因与岩性、火山机构及后期断裂构造密切相关,找矿标志明显,找矿潜力较大。  相似文献

Many advertising repetition studies have demonstrated wear-out effects, and found several moderating variables. In the context of Internet banner ads, this study examines the effects of repetition on attention, memory, and attitude, and identifies the moderating role of animation. By analyzing data on users’ actual visual attention, we found attention wear-out occurs with static but not with animated banner ads, which consequently influences the downstream effects: Compared to a static banner ad, an animated ad barely attracts consumers’ attention initially, resulting in worse memory performance and attitude in the beginning. However, with repeated brief exposures, animated banner ads eventually catch up with the static ads on memory and generate even better performance in terms of attitude. To summarize, animations signal the users the existence of ads and lead to ad avoidance behavior, but after repetitive exposures they induce positive user attitude through the mere exposure effect. Both the theoretical and practical implications are explored for using animation on the banner ads.  相似文献

植物胶冲洗液在东乌旗阿吉勒铅锌矿钻探施工中的应用   总被引:2,自引:0,他引:2  
内蒙古东乌旗阿吉勒铅锌矿区地层复杂,钻进过程中经常遇到多个构造破碎带,以凝灰岩和碳质板岩为主,蚀变发育,在泥质、硅质胶结段极易遇水膨胀、水化分散,造成坍塌、缩径等护壁难题。在采用多种冲洗液效果不理想的情况下,试验应用了植物胶低固相冲洗液,达到较好的防塌效果,且适应性强、粘度适中,形成的泥饼薄而致密且有韧性,成功地解决该矿区钻孔护壁难题。以ZK1507钻孔为例,阐明了所采用的冲洗液在水敏性地层取得明显的防塌效果。  相似文献
