商品个性标志的定义及其在美国流行文化中的角色

在过去的一个多世纪,商品的个性标志一直是美国人钟爱的广告工具。各种各样被广告商作为传播体系的＂会说话的动物＂和＂会跳舞的产品＂已悄无声息地蔓延在美国的流行文化中。1982年,有人在做调查后发现,凡是商品特征明显的广告,在改变品牌偏好的能力上要比同行业其他品牌强。这一点表明社会正在接收商品个性标志这样的讯息。然而,尽管商品个性标志的运用在广告商和消费者中大受欢迎,却几乎被完全遗忘在广告和流行文化研究的角落。本文将从相关文学的角度解析什么是商品个性标志,以及其如何运用在现代广告业中,并与消费者进行交流。     

Evaluating effects of atmospheric CO2 on stability of global climate: a cell-to-cell mapping approach

Atmospheric carbon dioxide concentration [CO2], incoming solar radiation and sea ice coverage are among the most important factors that control the global climate. By applying the simple cell-to-cell mapping technique to a simplified atmosphere-ocean-sea ice feedback climate model, effects of these factors on the stability of the climatic system are studied. The current climatic system is found to be stable but highly nonlinear. The resiliency of stability increases with [CO2] to a summit when [CO2] reaches 290 μL/L which is comparable to the pre-industrial level, suggesting carbon dioxide is essential to the stability of the global climate. With [CO2] rising further, the global climate stability decreases, the mean ocean temperature goes up and the sea ice coverage shrinks in the polar region. When the incoming solar radiation is intensified, the ice coverage gradually diminishes, but the mean ocean temperature remains relatively constant. Overall, our analysis suggests that at the current levels of three external factors the stability of global climate is highly resilient. However, there exists a possibility of extreme states of climate, such as a snow-ball earth and an ice-free earth.     

体力活动与癌症生存研究的10大问题

摘要：今天的美国有1 400万的癌症存活者,其中的很多存活者中都接受了多种治疗,包括手术、放疗、化疗、靶向治疗等。这些治疗能够延长生存时间,但同时也会带来很多急慢性的副作用,危害健康,影响生活质量。体力活动（PA）与癌症生存这一领域发展迅速,主要研究PA对癌症患者的影响。基于该领域的研究进展,提出了以下10大研究问题：1）PA能够降低癌症复发风险、和/或提高存活吗？2）PA能够影响癌症治疗决策、完成率、和/或患者对治疗的反应吗？3）癌症存活者的最佳运动处方是什么？4）静坐少动行为对癌症存活者有何影响？5）癌症存活者最有效的体力活动干预方案是什么？6）哪些癌症会影响病人对PA的反应？7）癌症存活者进行体力活动时需要注意的安全问题有哪些？8）哪些具体的癌症症状可以由PA解决？9）对于癌症晚期患者,体力活动还有何作用？10）如何将体力活动研究结果转化到临床和社区肿瘤实践中来？上述问题的回答至关重要,这不仅关系到体力活动和癌症存活这一研究领域的发展,更重要的是,能够为每年数百万新诊断为癌症的病人、正在接受癌症治疗的病人、治疗结束处于恢复中的病人或是那些正在与晚期癌症抗争的病人带来福音。     

迷上练习场

在许多职业赛事上,你不用破费很多就可以大有所获。乔·狄克逊的下巴紧紧贴在球场的钢丝网上,场内的罗杰·费德勒现在离她只有不到5码远。这位她最喜爱的网球选手,在她的注视下练习完上旋发球后,接着开始练习正手抽击。这是一记典型的费德勒式正拍,球"嗖"地飞出,刚刚过网,狠狠地砸在了边线上。狄克逊情不自禁地吹了个口哨,费德勒轻     

巴黎风情画——Blizzard WWI 2008赛场日记

很荣幸参加2008 Blizzard Enter- tainment Worldwide Invitational,作为WE魔兽世界竞技场战队的成员。第一次参加《魔兽世界:燃烧的远征》(World of WarCraft:The Burning Crusade)的竞技场大赛,虽然最后没能取得理想的成绩,但从魔兽世界目前极少的线下赛来看,WWI确实是一次难得的锻炼机会,这次失败也促使我更加努力的练习,对胜利的渴望,遗憾绝对不会留到下次!     

分析VS山寨DotA 6．57C火爆的原因

Data我已经近一年没有怎么碰过了,不是说我不喜欢DatA,我确信我一直都在深深的喜欢。但是自从两年前我把自己的爱好转变成了职业（一直做编辑嘛）,玩DatA的时候却一直提不起来兴趣。也难怪,天天看DatA相关的东西,想不审美疲劳都难,再也回不到当初把DatA当爱好的年代了。最近才感觉稍微好了一点,每天下班回家路人娱乐逐渐恢复水平。     

浅谈初级DotA CW阵容与节奏的掌握

DotA游戏基本可以分为以下几个层次：单机AI、路人战、IH、CW比赛。当你厌倦了每天在路人房里孤军备战,而有时队友又让你无奈。或许会找到一个小团体进行IH、内战、开黑,而开黑时往往双方实力悬殊,不能良好地发挥个人实力,基本会养成一些路人战的坏习惯。这时找一个大的平台,进行CW吧!这更正式、更有竞技性,双方都有很强实力的比赛是非常精彩的。其中在IH以后就要考虑阵容问题了,而高等CW还要考虑相互克制关系,团战破解对方优势的打法,这里主要谈一下目前较热的初级CW的一些细节。     

《电子竞技》专访：走近波兰战神NEO

今天《电子竞技》特约记者N.n为大家带来一个neo的独家采访。采访的过程其实是一波三折的,早在一个月前我们打算为这位憨态可掬的战神小朋友（呃,憨态可掬,原谅我用了这个词,暂时没有想到别的形容他可爱的词）做一个特别专访。     

Kinetic comparison of a side-foot soccer kick between experienced and inexperienced players

The aim of this study was to identify critical kinetic variables that lead to increased ball velocity during a side-foot passing kick in soccer. Seven experienced male soccer players and eight inexperienced players participated in the experiment. They were instructed to perform side-foot kicks along the ground with maximum effort with an eye on the target line. The joint angles, angular velocities, and torques of the kicking leg were determined based on the three-dimensional kinematic data. The mean ball speed of the experienced group (21.4 +/- 1.5 m/s) was significantly faster than that of the inexperienced group (16.0 +/- 1.0m/s; P < 0.001). The motions of the inexperienced players tended to be less dynamic than those of the experienced players. The most noticeable difference in the kinetics of the kick was found in the hip flexion torque throughout the back-swing phase until the leg-cocking phase. The mean peak value of the experienced group (168 +/- 20 N x or m) was significantly greater than that of the inexperienced group (94 +/- 17 N x or m; P < 0.001). To increase ball speed during a side-foot passing kick, the generation of hip-flexion torque during the earlier stage of kicking is critical.     

俄罗斯高等教育现代化进程中的质量问题

在欧洲高等教育一体化进程的影响下,正在经历转折阶段的俄罗斯高等教育领域开展了国家统一考试和国家记名投资试验,并开始实行学分制,但这些举措在实施过程中还存在一系列问题,需要做大量的工作,以切实保障高等教育的现代化、国际化的实现,提高高等教育质量。
