http://thebluecarboninitiative.org Fact box 1. The colours ofcarbon: Brown, Black, Blue and Green Google translate: 事实框 1. 碳的颜色:棕色,黑色,蓝色和绿色 我的翻译:事实框 1. 碳的颜色:棕色、黑色、蓝色和绿色 Climate Change has driven widespread appreciation of atmospheric CO 2 as the main greenhouse gas and of the role of anthropogenic CO 2 emissions from energy use and industry in affecting temperatures and the climate – we refer to these emissions as “brown carbon” for greenhouse gases and “black carbon” for particles resulting from impure combustion, such as soot and dust. The Emissions Trading System of the European Union (EU-ETS) is a “black-brown carbon” system as it does not incorporate forestry credits. The Kyoto Protocol’s Clean Development Mechanism (CDM) doesin principle include forestry credits, but demand (in the absence of a linking directive and demand from the EU-ETS) and prices have always been too low toencourage success, so CDM has also become, for all practical purposes, another “black carbon” mechanism. Google translate (谷歌翻译) : 气候变化已促使大气二氧化碳作为主要温室气体和能源使用和工业的人为二氧化碳排放在影响温度和气候方面的作用的普遍欣赏 - 我们将这些排放称为温室气体的“棕色碳”和“黑色 碳“用于由不纯燃烧产生的颗粒,例如烟灰和粉尘。 欧盟的排放交易体系( EU-ETS )是一个“黑棕色碳”体系,因为它不包括林业信贷。 “京都议定书”的清洁发展机制( CDM )原则上包括林业信贷,但是需求(在没有链接指令和欧盟排放交易体系的需求的情况下)和价格一直太低而不能鼓励成功,因此清洁发展机制 ,为所有实际目的,另一个“黑碳”机制。 我的翻译:气候变化让我们普遍地意识到 大气中的二氧化碳是 主要温室气体, 由于能源使用和工业产生出来的(既人为的)二氧化碳排放 在影响温度和气候。 我们将这些排放分为 “棕色碳”(来自于温室气体排放)和“黑色 碳”(来自燃烧剩下的颗粒,例如烟灰和粉尘)。 欧盟的排放交易体系( EU-ETS )是一个“黑色-棕色碳”体系,因为它不包括林业信贷( forestry credits )。 “京都议定书”的清洁发展机制( CDM )原则上包括林业信贷,但是需求(在没有链接指令和欧盟排放交易体系的需求的情况下)和价格一直太低,而不太可能成功;因此,清洁发展机制 实际上就是另一个“黑碳”机制。 Terrestrial carbon stored in plant biomass and soils in forest land, plantations, agricultural land and pasture land isoften called “green carbon”. The importance of “green carbon” is beingrecognized through anticipated agreement at the United Nations Framework Conventionon Climate Change Conference of the Parties (COP) in Copenhagen, December 2009,which includes forest carbon – through various mechanisms, be they REDD and afforestation, REDD-Plus, and/or others (e.g. ‘Forest Carbon for Mitigation’).The world’s oceans bind an estimated 55% of all carbon in living organisms. Theocean’s blue carbon sinks – particularly mangroves, marshes and seagrassescapture and store most of the carbon buried in marine sediments. This is called“blue carbon”. These ecosystems, however, are being degraded and disappear atrates 5–10 times faster than rainforests. Together, by halting degradation of“green” and “blue” carbon binding ecosystems, they represent an emissionreduction equivalent to 1–2 times that of the entire global transport sector –or at least 25% of the total global carbon emission reductions needed, with additional benefits for biodiversity, food security and livelihoods. It is becomingincreasingly clear that an effective regime to control emissions must controlthe entire “spectrum” of carbon, not just one “colour”. GT: 储存在植物生物 量 中的陆生碳和林地,人工林,农业用地和牧场中的土壤通常被称为“绿色碳”。 “绿色碳”的重要性正在通过 2009 年 12 月在哥本哈根举行的“联合国气候变化框架公约”缔约方会议( COP )的预期协议得到承认,其中包括森林碳汇 - 通过各种机制,无论是 REDD 和植树造林, REDD-Plus 和 / 或其他(如“森林碳减排”)。世界海洋约占活生物体中所有碳的 55 %。海洋的蓝色碳汇 - 特别是红树林,沼泽和海草捕获并储存埋藏在海洋沉积物中的大部分碳。这被称为“蓝碳”。然而,这些生态系统正在退化,消失的速度比雨林快 5-10 倍。通过阻止“绿色”和“蓝色”碳结合生态系统的退化,它们的减排量相当于整个全球运输部门的 1-2 倍 - 或至少占全球所需碳减排总量的 25 %为生物多样性,粮食安全和生计带来额外的好处。越来越清楚的是,控制排放的有效制度必须控制碳的整个“光谱”,而不仅仅是一种“颜色”。 我的翻译:储存在植物中的陆生碳,以及林地、人工林、农业用地和牧场的土壤中的碳,通常被称为“绿碳”。 “绿碳”的重要性通过 2009 年 12 月在哥本哈根举行的“联合国气候变化框架公约”缔约方会议( COP )的预期协议正在逐步得到承认,其中包括森林碳汇-通过各种机制,无论是 REDD 和植树造林, REDD-Plus 和 / 或其他(如“森林碳减排”)。所有活生物体中的 碳, (约) 55 %是 储存 在(世界)海洋中。海洋的蓝色碳汇-特别是红树林、沼泽和海草捕获并储存埋藏在海洋沉积物中的大部分碳-被称为“蓝碳”。然而,这些生态系统正在退化,其消失的速度比雨林快 5-10 倍。通过阻止这些储存着“绿碳”和“蓝碳”的 生态系统的退化,其减排量相当于全球运输系统的碳排放总量的 1-2 倍-或至少占全球所需碳减排总量的 25 %,而且还能为生物多样性、粮食安全和生计带来好处。越来越清楚的是,控制排放的有效制度必须控制碳的整个“光谱”(既各种颜色的碳),而不仅仅是一种“颜色”(的碳)。 In the absence of “Green Carbon”, biofuelcropping can become incentivized, and can lead to carbon emissions if it is notdone correctly. The conversion of forests, peatlands, savannas and grasslands to produce food-crop based biofuels in Brazil, Southeast Asia and the UnitedStates creates a biofuel carbon debt by emitting 14 to 420 times more CO 2 than the annual reductions in greenhouse gases these biofuels provide by replacing fossil fuels. In contrast, biofuels produced from waste biomass and crops grown on degraded agricultural land donot accrue any such carbon debt. GT: 在缺乏“绿色碳”的情况下,生物燃料种植可能会受到激励,如果不能正确完成,可能导致碳排放。 在巴西,东南亚和美国,森林,泥炭地,热带草原和草地转化为生产基于粮食作物的生物燃料,通过排放比年温室气体减少量多 14 至 420 倍的二氧化碳产生生物燃料碳债务这些生物燃料 通过替换化石燃料提供。 相比之下,由废弃生物质和生长在降低农业用地上的作物生产的生物燃料不会累积任何这样的碳债务。 我的翻译:如果我们忽略“绿碳”(的作用), 生物燃料的生产可能会受到激励;如果不能正确规划,可能导致碳排放。 在巴西、东南亚和美国,森林、泥炭地、热带草原和草地被转化为生产基于粮食作物的生物燃料,目的是替换化石燃料;但是, 这比不转化(这些土地)反而多排放 14 - 420 倍的二氧化碳 (既产生相反的作用),因为这些土地上的原有的植物 具有一定的减少温室气体的作用。 相比之下,由废弃生物和生长在低产农业用地上的作物生产的生物燃料,则不会造成碳排放。

[转载]最不抱希望的青基居然中了(三流学校,第一次申请)
zhao1198 2011-8-22 07:25
说实话,一直都不抱好大的希望,我们这种学校中个基金太难了。当初给自己定的目标是35岁之前中个青基,总共有5次机会,没想到第一次就中了。 之前看着坛子里有路子的朋友早早知道消息,心想今年又会当观众看一群人的狂欢。不想昨天得知中了,心里那个狂喜啊,一天都感觉像做梦一样,就像当初得知老婆怀了宝宝一样。 标书是博士内容的延伸,但对自己来说是一个较新的方向,所以参阅了不少资料,但我们这种学校看个全文都难,只有动用关系,厚着脸皮到处求。标书在交之前还 大改过,把原来的两部分内容砍掉一半,集中力量写好自己不熟悉那一部分。感觉这样目标更明确,更有深度。还有,虽然自己对该方向不是特别熟悉,但参加过该 方向的国基,并且自己主持了一个有关的省基金,在标书后面详细地说明了课题与前两个基金的不同之处。开始一直犹豫要不要列出来,怕列出来后专家会觉得先把 那两个课题做好再来申请。但思考再三还是列了出来,并着重强调了侧重点不一样,心想另一方面还会让专家觉得有这方面的研究经验。 感觉在申请时还是不要刻意隐瞒什么,真诚或许也会感动专家。此外,自己研究基础一般,论文也不是太多,但有一片4.8的;还有一些没发表的数据列在标书里当作了前期基础。 感谢坛子里的朋友提供的优秀标书,看了后感觉收获不小。感谢科研处的同志,他们放假还在坚守岗位,并且之前聘请专家给标书提出了宝贵意见。感谢漂亮的老婆给我生了个可爱的宝宝,让我成为了lucky dog. 接下来感觉压力也不小啊,要高质量地完成标书的目标还有很长的路要走。中了的朋友我们一块加油吧;暂时没中的也不灰心,人生的路还很长,机会总是有的。我觉得先把家庭经营好更重要,毕竟那才是心灵的港湾,事业的加油站。

Green Bay
热度 2 chemicalbond 2011-2-8 13:36
Green Bay
Green Bay 是美国威斯康星州的一个人口只有十万左右的城市。在美国职业橄榄球联盟(NFL)32个球队所在城市里面,Green Bay 是最小的一个。可是他们的球队却在本赛季一路过关斩将,最后在昨天晚上获得了超级杯。【注:1.球队名为 Pakers,起源于最早的一个生产包装品的赞助商。2.超级杯在美国是收视率最高的电视节目,每年都几乎在春节前后,也差不多是北方最寒冷的日子。】 更让我和很多我的朋友们难忘的是,Pakers 两次击败了费城的鹰队(Eagles)。第二次是在淘汰赛的第一轮,让无数球迷对曾经让大家看好的 Eagles 大失所望。 Green Bay 球队很有特色,不过最值得称道的当然是今年超级杯的 MVP, Aaron Rodgers。记得几年前第一次看他的比赛就为他的沉着和自信所吸引----大概那就是传说中的成熟男人的魅力。在未来的很多年里面,这个具有超高传球命中率的80后球星将始终成为很多人的粉丝,以及无数人的恶梦。 我自己对Green Bay也有些特殊的感情。那是因为它是我在芝加哥学会开车之后远行的第一个城市。Green Bay坐落在威斯康星北部,靠近密西根湖,湖边的风景非常优美。在那之后的很多年,直到游览了美加边境的千岛湖,我才重新有了步入仙境的感觉。。。。。。 期待着再次游览Green Bay,最好在那里看一场Pakers 和 Eagles之间的比赛。至于谁赢谁输,那都将是一个不太重要的结果。

Red tide, green tide, ... and black tide?
热度 1 zuojun 2011-1-10 09:48
The year 2011 started well, with more work than I can handle and none for free. (Yes, I work for free some time.) Among the things I have done so far (less than 10 days into the new year) is to lightly edit an article of more than 10, 000 words, in 24 hrs. I could have done it if it were truly light editing. Instead, I was doing re-translation half of the time. So, I asked for 48 hrs. As I edited along, I saw "black tide invasion." I stopped: "I have heard of red tide and green tide. But, what is this black tide?" Well, I had the Chinese version right in front of me, so I checked. Guess what it was supposed to be? 黑潮入侵 Happy translating!

Green tides off China (4): More needs to be done and can be done …
zuojun 2010-7-21 08:28
After LIU's presentation in Yantai, my first thought was to pay the nori farmers to clean up the mess after they harvest the nori. I was laughed at, literally, for being so naive. Ok, I was, because someone showed me an estimate for such a payment, too much RMB to be realized, unless Bill Gates took interest in this experiment. Then, I read something else, including this article at EarthSky: Daniel Sigman on ocean algae and global cooling ... Daniel Sigman: Algae require nitrogen to grow, and their bodies, in turn, fuel the rest of the ocean food web. Sigman explained that by measuring algaes use of nitrogen, he can gauge how much these ancient organisms used another important element carbon dioxide, or CO2. All earthly plants use CO2 for photosynthesis. CO2 is also a major greenhouse gas in Earths atmosphere. Excess CO2 warms the Earth. Daniel Sigman: The ocean is responsible for lowering carbon dioxide in the atmosphere as much as forests on land are. Thats because algae take CO2 out of surface water. And, when the algae die, Sigman said, they sink. Daniel Sigman: After the algae sink, they transfer the CO2 where it cannot escape into the atmosphere. This helps cool the planet. Dr. Sigman is currently working to determine the role the ocean played in the global cooling that caused the last ice age. His early research indicates that algae in polar oceans might have played a role. This illustrates how the collective activity of many small creatures can exert a big influence on climate, he said. Daniel Sigman: If you imagine more organic matter being produced in the worlds ocean surface waters and sinking to the deep ocean, that means more carbon removal from the atmosphere. That also means a lower concentration of carbon dioxide in the atmosphere. Sigman described the combined activity of many small creatures the algae as a biological pump. In other words, these living creatures acted to remove carbon dioxide from the atmosphere and bury it in ocean sediments. He said that because carbon dioxide acts to cool Earths atmosphere this biological pump acting in Earths oceans might have helped triggered past ice ages. ...

互联网版参考文献管理软件NoteFirst 欢迎各界朋友测评
热度 1 paperopen 2010-7-16 15:05
  经过近2年的开发,互联网版参考文献管理软件NoteFirst终于结束了内测阶段,今天Ver1.2发布了,因此敢让朋友和用户进行试用了。   NoteFirst的主要功能包括个人文献管理软件(文献分类、搜索、价值度标定、和全文文件的关联等)和论文写作助手(把收藏文献作为引文插入到Word文档,自动形成规范的参考文献列表)。 1开发NoteFirst的初衷   国内外已经有类似的软件,如EndNote,RefWorks,国内的NoteExpress。为什么还要开发呢? 1.1开放存取绿色道路的实践者   目前开放存取的绿色道路中,有很多作者由于对发表的文章进行自存档时,需要填写标题、作者、摘要、期刊等很多元数据,影响了大家自存档的积极性。如果能提供一种增值工具,让大家不用再花费额外时间做额外工作,就能实现自己发表论文的自存档。   NoteFirst可以自动识别那些论文是用户自己的,那些是用户收集的,实现用户自有版权文献在NoteFirst上的自存档。   这是我开发NoteFirst最原始的动机。希望通过NoteFirst,另辟蹊径,进行开放存取绿色道路的实践,建设有世界影响的中国的开放存取绿色仓储平台。这项工作对作者、期刊社来讲都是有积极作用的,毕竟大多数的作者和期刊是以提高学术影响为主要目的。 1.2目前国内外参考文献管理软件尚不能满足要求   国外参考文献管理软件对中文期刊参考文献格式不能很好的支持,会出现这样的问题:    杨卫娟, 周俊虎, 刘建忠, et al. 选择催化还原SCR脱硝技术在电站锅炉的应用 . 热力发电 2005;34(9):10-14.   国标要求参考文献中,3个作者后应该使用,等代替其他作者,在英文文献中才使用et al来代替其他作者。   国内参考文献解决了这样的问题,但是国标的理解还是不到位,会出现这样的问题:    Wan Q J ,Wang X X , Wang X. Poly(malachite green) film: Electrosynthesis, characterization ,and sensor application . Polymer, 2006, 47:7684-7692.   国标要求,中文作者的汉语拼音不得缩写。上面的参考文献满足国外标准,但不能自动区别英文文献中那些作者是中文作者的汉语拼音。   图1是用NoteFirst自动形成的参考文献示例。   图1 采用NoteFirst自动形成的参考文献示例 1.32NoteFirst的特点 2.1互联网版论文助手   不同计算机上登录同一账户时可实现数据自动同步,这样家中计算机上收集的文献(包括对应的全文文件)会自动出现在办公室的计算机中。   目前国内的参考文献软件是单机版。   NoteFirst为大互联网软件,不像国外网络版参考文献管理软件那样,要求用户所在机构必须购买架设专用的参考文献管理服务器,用户只要在NoteFirst上注册账号即可使用。   国外也有大互联网版软件,但没有客户端,文献管理全部基于浏览器,工作效率受网络环境的制约。   国外也有对带客户端的大互联网版参考文献软件,但对中文期刊参考文献格式的支持不够好。 2.2对参考文献国家标准的全面支持   NoteFirst支持多语言方案,一个引文样式中可以为不同语言的引文提供不同的样式,例如,国标GB/T 7714-2005《文后参考文献著录规则》中规定,期刊论文作为参考文献时,如果作者超过3个,可以只列出前面3个作者,如果是中文文献,省略的作者用 ,等代替,如果是英文文献,省略的作者要用 et al代替。这是大多数国外软件做不到的。   此外,即便参考文献为英文时,如果作者是中国人,要求采用汉语拼音的中国作者姓名一定不缩写。但是大多数期刊在参考文献格式中,要求英文作者采用姓 名缩写规范,这一点和国标是冲突的。NoteFirst不仅仅能区分题录的语言,还要区分作者的国籍。即便是国内的参考文献管理软件业目前也无法支持。 2.3支持EI、SCI中文收录期刊的双语参考文献   EI、SCI收录的中国期刊要求提供中英双语参考文献。例如:    马志刚.基于小波分析的车辆噪声特征提取方法研究 .电子设计工程,2010,18(1):3-7.    MA Zhi-gang. Research of feature extraction of vehicle noise based on wavelet analysis .Electronic Design Engineering, 2010,18(1):3-7. 2.4NoteFirst提供永久免费的普及版版本   NoteFirst的普及版没有使用期限限制。   普及版的限制就是在单文档中只能插入20个引文,可以管理500个文献。这对于一般的期刊论文作者来说基本够用了。 3欢迎各界朋友进行测评和指导   大家知道,一个软件的成熟需要时间,更需要用户的参与。   欢迎科技界和期刊界朋友来对我们的产品进行测评。   NoteFirst的下载地址: http://www.notefirst.com/download   可以为测评的期刊届朋友设定期刊引文样式。

Abstract A massive bloom of macroalgae occurred in the western Yellow Sea at the end of May, 2008, and lasted for nearly 2months. The surface-drifting macroalgae was observed to accumulate in a pattern dominated by linear bands. The maximum length of individual algal bands exceeded 10km and the distance between neighboring bands ranged from hundreds of meters to 6km. Seven satellite images were analyzed to determine the distances between neighboring bands. Proportions of about 24%, 38%, and 22% are responsible for the separation distances smaller than 1km, between 1 and 2km, and between 2 and 3km, respectively. The separation of about five percent of the bands exceeds 4km. The probability distribution of the separation distance is quite close to log-normal which is that found in Langmuir circulation. However, the observed algal band separation greatly exceeds the distances between convergence lines reported in Langmuir circulation. References Csanady, 1994 G.T.

[转载] Green tides off China (2): The latest research paper on these green tides

If you search under keywords Qingdao via Web of Science, you can find a JGR paper by Hu et al. JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 115, C05017, 8 PP., 2010 doi:10.1029/2009JC005561 On the recurrent Ulva prolifera blooms in the Yellow Sea and East China Sea On the recurrent Ulva prolifera blooms in the Yellow Sea and East China Sea Chuanmin Hu College of Marine Science, University of South Florida, St. Petersburg, Florida, USA Daqiu Li College of Marine Science, University of South Florida, St. Petersburg, Florida, USA Institute for Environmental Protection Science at Jinan, Jinan, China Changsheng Chen SMAST, University of Massachusetts Dartmouth, New Bedford, Massachusetts, USA Jianzhong Ge State Key Laboratory of Estuarine and Coastal Research, East China Normal University, Shanghai, China Frank E. Muller-Karger College of Marine Science, University of South Florida, St. Petersburg, Florida, USA Junpeng Liu Ocean Remote Sensing Institute, Ocean University of China, Qingdao, China Feng Yu Ocean Remote Sensing Institute, Ocean University of China, Qingdao, China Ming-Xia He Ocean Remote Sensing Institute, Ocean University of China, Qingdao, China A massive bloom of the green macroalgae Ulva prolifera (previously known as Enteromorpha prolifera ) occurred in June 2008 in the Yellow Sea (YS), resulting in perhaps the largest green tide event in history. Using a novel index (Floating Algae Index) and multiresolution remote sensing data from MODIS and Landsat, we show that U. prolifera patches appeared nearly every year between April and July 20002009 in the YS and/or East China Sea (ECS), which all originated from the nearshore Subei Bank. A finite volume numerical circulation model, driven by realistic forcing and boundary conditions, confirmed this finding. Analysis of meteorological/environmental data and information related to local aquaculture activities strongly supports the hypothesis that the recurrent U. prolifera in the YS and ECS resulted from aquaculture of the seaweed Porphyra yezoensis (or nori ) conducted along the 200 km shoreline of the Subei Bank north of the Changjiang (Yangtze) River mouth. Given the continuous growth in aquaculture efforts in the region, similar macroalgae bloom events, such as the summer 2008 event, are likely to occur in the future, particularly between May and July. This was confirmed by the 2009 bloom event in the same regions and the same period. The profit of the local P. yezoensis aquaculture industry (16,000 Ha in 2007) is estimated as U.S. $53 million, yet the cost to manage the impact of the summer 2008 U. prolifera bloom exceeded U.S. $100 million. Therefore, better strategies are required to balance the economic benefit of seaweed aquaculture and the costs of environmental impacts.

Green tides off China (1): Remember the news about Qingdao in summer 2008?
zuojun 2010-7-15 08:20
Remember this dramatic photo at BBC News website? Well, if you look at the lower-right corner, the photo is credited to LIU Dongyan (yic.ac.cn), a female marine biologist I met in mid June this year in Yantai. Liu is also featured in this BBC report below; she is the lead author of the research paper this report is based on. Origin of giant bloom discovered By Matt Walker Editor, Earth News (Page last updated at 14:06 GMT, Wednesday, 6 May 2009 15:06 UK) Related articles: Algae invade China Olympic venue (look to the right of the photo for the corresponding link) (Page last updated at 10:25 GMT, Tuesday, 1 July 2008 11:25 UK) Tackling Qingdao's invading algae (look to the right of the photo for the corresponding link) By Quentin Sommerville BBC News, Qingdao (Page last updated at 08:28 GMT, Thursday, 3 July 2008 09:28 UK) Algae cleared from Olympic venue (look to the right of the photo for the corresponding link) By Quentin Sommerville BBC News, Qingdao (Page last updated at 11:55 GMT, Tuesday, 15 July 2008 12:55 UK) How should I put it? China is re-writing the history. As you can tell from this Web site by Ifremer: Introduction to the green tides phenomenon You may wonder why I am writing a Blog on this old stuff. Well, I am hoping that you can help, because these green tides are not going away unless we do something about them. (To be continued.)

你是真的爱环保产品吗?
热度 2 lulush 2010-6-4 14:41
你是否买过以下产品:再生纸笔记本?节水的抽水马桶?环保灯泡?无氟冰箱? 在一股环保的浪潮下,是什么促使你购买这些产品,而它们又会给你的行为带来哪些影响? 最近发表在 Journal of Personality and Social Psychology(JPSP) 和 Psychological Science 上的两篇文章,分别从不同角度探讨了这个问题,结果使人惊讶。 Griskevicius 及其同事的研究发表在 JPSP 上,他们认为,对地位的追求会促使人们购买环保产品。跟其他的同类产品比,环保产品往往价美物廉,所以人们购买环保产品,实际上是牺牲自身利益而造福他人。这种行为恰恰符合进化心理学 昂贵信号 (costly signal) 理论 的预期。该理论认为,为了向其他人传达关于自己的正面信息,需要采用难以作假的信号。如,一个人经常请邻居大吃大喝,这种行为就在向他人传递一个信号,用于说明自己是个慷慨靠谱可依赖之人,又如,一个小伙儿给女朋友买了很多衣服首饰,也是在传递我很爱你,我愿意为你付出的信号。信号的昂贵也可以通过其他方面表达,如为了证明对姑娘的爱,小伙儿投河了,割腕了这也算是昂贵的信号之一。当一个人购买环保产品时,他向周围传递的信号是:我是一个关心他人、乐于为大众而牺牲自己的人而这,往往与高地位有关。 研究者通过让被试阅读一个小故事,来启动他们对地位的渴望。故事描述的是被试大学毕业后进入一家大公司,高档的办公环境,有前景的工作,以及超越其他同龄同事的升迁机会。阅读后,被试对社会地位的渴望以及对名望的渴望显著高于控制组。在实验一中,在环保产品与其他产品价格相同的情况下,被启动了渴望地位的被试,更愿意选择环保产品。 实验一的结果并不出乎意料,有趣的是实验二。根据信号理论,如果是信号,重要的是要有观众,所以购买产品是在公开场合还是在私底下,会影响被试的购买决策。在实验二中,被试除了被分到地位组和控制组,在每个组内还进一步的细分为在公共场合购买,或在家网络购物。发现地位组的被试,如果是在公共场合购物,那么他们选择环保产品的可能性则大大增加;如果是在家购物,那么他们更有可能选择非环保产品。 实验一和实验二中的环保产品与其他产品价格相同。根据昂贵信号理论,如果为了展示自己有实力,那么渴望地位的被试则更愿意买贵的东西。实验者将环保产品设定为比较贵或比较便宜,发现地位组的被试确实更愿意购买更为昂贵的环保产品。 另外一组实验发表在著名的心理学娱乐杂志 Psychological Science 上, Mazar 及其同事发现,尽管人们认为购买环保产品的人通常更为友善及乐于合作,但是,接触环保产品和购买环保产品却是两个概念:即接触环保产品会让人更加友善,而购买环保产品会让人有 更爱骗人 以及 更不合作 。 研究一很简单,是请被试对购买环保产品及一般产品的人在合作性乐于助人及有道德方面进行打分,发现人们认为购买环保产品的人在以上方面确实高出一筹。 研究二有趣一些。将被试分为了接触组及购买组。购买组在网上虚拟的采购 25 元的货品,而接触组则是对这些货品的设计、描述等进行打分。他们看到的货品里面,一组是绿色产品比较多,一组是普通产品比较多。然后,所有被试进行独裁者游戏(是行为经济学非常非常常见的一个实验,经常用来测友善性、乐于助人等)。结果发现, 接触 了环保产品的人,在独裁者游戏中倾向于给他人更多钱;而 购买 了环保产品的人,在独裁者游戏中倾向于给他人更少钱。 研究三进一步测试了环保产品的效果,前一启动步骤同研究二,然后测量被试 Cheating 的情况(分别用我前文提到的判断红点的测试和拿钱的测试)。研究发现,购买了环保产品的人,更容易作弊;而接触了环保产品的人,更不容易作弊。即购买环保产品就仿佛给自己买了一张好人证明,顶着我是好人的证明,就好干坏事儿了。 文章讨论了环保产品 启动 (priming) 与许可 (licensing) 两种不同的作用。启动是指接触环保产品可以激发人的助人意识;而许可是指既然被试已经买了环保产品,已经向大家展示了自己是个有道德的人,所以私底下来说,干点坏事儿也情有可原。文章点出了买和看同一产品产生的不同的启动效果。 Comments : 1 ,读全文可以看出 JPSP 和 Psychological Science 风格的不同。 JPSP 仿若大家闺秀,娓娓道来,精致细腻。而 Psychological Science 则更像大波妹,简单性感。 2 , Mazar 的研究二里两个主效应都不显著,但交互作用显著。学学人家是怎么从不显著的研究二、整出显著的实验三来的。 3 , Prime 的方法有很多种,测各种特点品质的行为实验也有很多种。需要再积累积累这些,收集利弊。其实,如果能自己整出个好用的行为测试 / 启动方法来,还是挺考验创造力的。 4 ,问卷的研究方法已经在心理学里渐渐被摒弃,多做做行为实验,争取再加上脑啊,认知啊之类的才是主流王道。 以后在每篇文章里再挑一些可以改进 / 进一步研究的地方: 1 ,人们传递了昂贵的信号之后,是否都更有可能做不道德的行为? 如给女朋友买了昂贵首饰后,脚踏两只船的可能性更高? --licensing effect 的进一步扩展。我命名为道德不应期 (Moral refractory )-- 这个题目很 sexy 吧,哈哈 。 2 ,我对独裁者游戏吐槽无力其中一个原因是这个测验使用的太过频繁,基本上学过心理学或行为经济学都会对此了解一二,如果这些人做被试,就仿佛打一副谜底已经被揭开的牌,效果不太好。在 Mazar 的研究结果中不太显著可能也与此有关吧。 Griskevicius, V., Tybur, J., Van den Bergh, B.
