从博客抄袭及不当回应事件看科研人员的心理亚健康问题
段伟文 2015-8-7 15:14
从博客抄袭及不当回应事件看科研人员的心理亚健康问题 前段博客抄袭及不当回应事件过去一段时间了。时值气候反复无常的仲夏,此事件引起了轩然大波,当事人立马成为众矢之的,也给其原单位造成了莫大的困扰。在此事件中,不容否认的是,当事人抄袭他人博文一事属实;而尤其引起网民反感的是,当事人对其不当行为引来的批评态度硬拗,其言论不仅不符合学术诚信的要求,甚至严重违背了社会公众的基本伦理认知。因此,各方的挞伐理所应当。当事人急删博客与微博相关内容,多少表明其自觉理亏或对后果的进一步发酵有所顾忌。有鉴于此,相关媒体报道的焦点是,对此恶性事件不能不了了之,并一再追问如何处理此事。由于此事事实清楚,单位的基本处理方式应该是严肃的批评教育、责令道歉并在一段时间内禁止网络发表与言论;相关网络也可以像学术期刊一样对其发表做出时限性乃至永久性的禁令;以此案例举一反三,单位与网站应制定出网络信息发布学术诚信规范及不端行为处理办法,以此规范相关言行。 在采取了这些“惩前毖后、治病救人”的必要的举措之后,还有一个问题值得深入考量,这涉及到对人本身的关怀,即当事人为什么会有这种极端不智的态度?其实,当事人“无权无势”,仅仅是一位一般的退休研究员,但又为何会做出这种搬起石头砸自己脚的事来?他早年经历坎坷,青年时代主要从事科学专业杂志翻译工作,其真正的哲学学术生涯很短,中间身体出现大问题,虽勉强通过职称等名利角逐,但不是博导,种种理想与现实的鸿沟和不够成功的事实对其的内心所造成的压力可想而知。故此事件的表象与社会观感恶劣确是事实,但深层的问题可能是不那么成功的知识人的心理亚健康问题。即便从常识的眼光来看,当事人的一些话语风格之怪异,其所编造的理由牵强还振振有词,皆可见其中存在着复杂的心理因素;这种怪异的言行实际上类似于儒林外史中的一些酸腐文人及其余绪方鸿渐、孔乙己等人的人格表现,而那些人的独白如果像今天这样拿到微博上晒,效果应该是类似的。 因此,对研究人员的心理亚健康问题给予一定的人文关怀,应该是由此事件引出的一个有价值反思视点。以人文社科研究人员与高校教师为例,特别是社科院的研究人员主要在家办公,加之教育部给社科院的研究生招生指标很少,没有多少学生可以交流,不那么有名的或业务不繁忙的大多数人其实十分寂寞。有的人耐得住寂寞做出了成就,但这种寂寞也使他们长期处于见物不见人、门朝天开的状况,其社交能力与情商的发展受到限制,很多时候容易话痨、偏激、耽于臆想、自说自话。对他们中的不少人来说,有机会说比说什么重要,而且很多时候会把臆想和猜测当作事实来讲。比方说当事人为狡辩提及的子虚乌有的学术不端行为媒体反应实验可能不是简单的杜撰,而掺杂着其关于可能的研究方法的臆想。在情绪不稳定的情况下,这些臆想的东西在其头脑中容易构建出一种自我兑现的诺言,进而在心理与言论上形成一种由“臆断式自我欺骗—自我求证—寻求更多臆想证词—反正我信了到信不信由你”的自欺与欺骗的罗生门。这些心理问题如果得不到及时有效的纾解,就会发展成严重的心理亚健康问题,它是导致很多学历、层级、文化程度高的人会在没有预兆的情况下爆发出偏执、硬拗等令人难以理解的行为的重要内因。我们应该曾经目睹或听说:一位平时很和气的领导或水平高的专业人员会因为门卫阻拦查证等大光其火、很多师生与同行合作关系最终以类似敌我关系结束...... 从科研人员的成长过程来看,很多人付出了高昂的代价却依然不那么成功是使心理亚健康情绪累积、放大乃至爆发的重要肇因。为了成就理想,科研人员特别是基础研究的学者往往牺牲良多,耽误婚嫁者有之,半路出家与中年学艺者有之,“避长扬短”与厚板钻孔者亦有之,但鉴于生涯规划、知识积累、研究方法、机遇把握、研究策略等方面的不足,使他们未能实现预想中的成功。而当自我认同和自我期许与其真实状况之间的落差大于其心理承受力时,心理亚健康的潘多拉的盒子就打开了:落寞、幽怨、孤愤、狷介、迂腐乃至狂傲与自暴自弃,这就是很多不那么成功的学者高处不胜寒的结构性人格悲剧所在。在创新驱动发展、建设创新型国家的今天,为了避免这种悲剧重演,我们应该从爱惜人才、关心人才的角度直面科研人员的心理亚健康问题,对此展开深入调研与多学科研究,寻找标本兼治的有效对策。

研究人员忙于搜罗报销凭据告诉我们什么 ? 黄安年文 黄安年的博客 / 2014 年 2 月 5 日 发布 春节期间 , 几位科学院和高校在职研究人员和教师来访和电话交谈学术研究生态 , 给我这样一种感觉,现在真有点程序员、统计员、财会员指导研究员的味道,研究人员为量化学术项目报销需搜罗各类凭据而烦恼不已。财务部门近来严格了报销手续和限制项目 , 项目立项决定通报本已滞后 , 而报销时间更加滞后,使得疏于票据准备的研究人员显得格外困难。在研究人员中,精于财务票据收集和统计的高手毕竟少之又少 , 往常无需件件商品或购物、交通活动保留发票等证据的,现在却要求件件有着落 , 活动当初并不确知这个项目究竟批了没有,自然更不在意票据完好保存 , 即使有所保存 , 时间不长 , 不能一下了像财会室那样立马找出来。报销又有限期 , 过期作废,这还不让所有需要项目费报销的人忙个不停。这样,平时不常聚在一起的研究人员,见面时的话题由学术转为集中于报表和报销凭据,可谓数钱票据真忙,一堆研究人员聚在一起数票据,交流报销诀窍,甚至互借票据的情况屡见不鲜,我这次借你几张票据应急对付,下次我得还你相应钱数的票据,因为有了可供报销的票据就等于有了钱票 , 在这没有钱万万不能的时代,能够不一丝不苟吗? 令人悲哀的是 , 这类情况还非个别,研究人员到了个个为报销发愁,单位财会人员需要验证一大堆难以笔笔刨根问底的单据,要花费多少人力?问题是并非中纪委组织专案组来查账,这样做,究竟有多大的必要呢,如果立项审批单位对于研究人员没有基本的信任,为什么要批钱呢 , 毕竟研究人员监守自盗的情况是个别的。你既然批了那么多项目费归研究人员使用 , 有材料证明项目保质保量地圆满完成了 , 不就结项了吗?至于钱怎么花需要件件有凭证吗?话说回来 , 即使提供了件件的凭证你能够保证件件是原件?这无疑是自找麻烦,因小失大 , 浪费了研究员、 统计员、 财会人的宝贵时光。这不是繁琐哲学是什么 ? 更有意思的是项目完成了 , 结果没有用完拨给的项目费,这省下来的钱 , 据说是要全部上缴的,连个分成或者让研究者继续使用都没有,这种规定同样是造成不花白不花心理的重要动因,那么请问勤俭办一切事业的精神到哪里去了 ? 同样令人不解的是没有立项或者没有项目费却有研究成果的学者没有获得丝毫的奖励 , 原因却是对于单位的 GDP 指标没有帮助,你说这种量化指标算个啥? 我确实感到了在职量化学术工作者的烦恼,也为自主学术 , 不受票据报销的烦恼而有所欣慰。不过,话说回来,再怎么烦恼,这钱本该属于自己的研究所得 , 再烦恼,还得烦恼地忙着找到足够的票据 , 并快乐地烦恼着 !

Collins scollins@sevilleta.unm.edu 505.277.6303 Scott is currently Professor of Biology Director of the Sevilleta LTER. His research interests include plant community dynamics; gradient models and structure; the role of disturbance in communities; fire ecology; patch dynamics; landscape ecology; grassland ecology; analysis of species distribution and abundance; pulse dynamics in aridland ecosystems. Welcome! Our research focuses on the impact of natural disturbances and global environmental change on mesic and arid grassland ecosystems. We are particularly interested in the interactive effects of fire, grazing and drought in mesic grasslands in North America and South Africa, and how rainfall variability, temperature change, and shrub encroachment affect aridland ecosystems in the southwestern US.

Our projects focus on terrestrial ecosystems and plant communities, links between biodiversity and human well-being, and the implications of interacting global and regional environmental changes. We work with a wide range of NGOs, government agencies, land managers and community members to bridge strong science to effective action. Hungate http://www4.nau.edu/Hungate_Lab/ Northern Arizona University Research in our group focuses on the roles of plants and microorganisms in ecosystem processes, especially carbon, water, and nutrient cycling. A major thrust of our research examines biogeochemical responses to global changes, such as rising atmospheric CO2, climate change, N deposition, and altered land use. For example, we are currently studying how elevated CO2 alters the hydrology of scrub woodlands, and how increased temperature influences the nitrogen cycle in grasslands. In addition to understanding ecosystem responses to such perturbations, we are also interested in how ecosystem responses can feed back to alter the pace and even direction of future global changes. A second major thrust of our research addresses how single species can affect ecosystem processes, for example, how infestation with the pion-needle scale alters the water budget of pion-juniper woodlands, or how mycorrhizae influence decomposition of fine roots. Harpole http://www.public.iastate.edu/~harpole/ I received my PhD from the University of Minnesota in 2005, working with David Tilman. My primary field site was at Sedgwick Reserve, near Santa Barbara, California. My dissertation focused on the role of multiple resource limitation for controlling biodiversity and invasions. I also worked at Cedar Creek Ecosystem Science Reserve in Minnesota testing niche and neutral theory. As a postdoc I worked with Katharine Suding at UC Irvine. We are applying a predictive theoretical framework to understanding the roles of cattle grazing, N-deposition and spatial processes as drivers of alternative states in Northern and Southern California grasslands. I joined the Ecology, Evolution and Organismal Biology Department at Iowa State University in 2008.

Sala Julie A. Wrigley Chair and Foundation Professor School of Life Sciences and School of Sustainability Our research revolves around three major themes that closely interact with each other: (1) the effects of changes in climate on the functioning of arid and semiarid ecosystems, (2) scenarios of changes in biodiversity and their consequences for the functioning of ecosystems, and (3) effects of woody-plant encroachment on ecosystem services. We tackled these three themes at multiple scales from the local to the regional and global. We are driven by questions and hypotheses and use multiple tools to address them; including synthesis, manipulative field experiments, and simulation modeling. We work extensively in the development of scenarios as a way of simplifying, understanding, and communicating the complex relationships that emerge from the study of social-ecological systems. We have worked in many regions of the world from the Patagonian Steppe and grasslands of the Great Plains of North America to arid ecosystems of South Africa and the annual grasslands of California. Currently, most of the experimental work is focused on the Chihuahuan Desert, at the Jornada Long Term Ecological Research site. Our research effort is closely integrated with our education and outreach mission. We collaborate with several institutions beyond Arizona State University including Asombro Institute for Science Education and SARAS .

The Hawaiian Islands are the focus of the majority of studies. Our group has looked at nutrient dynamics in the soil profile, litter, native forest ecosystems, forest and grassland systems affected by invasive species and agricultural systems. Studies have documented how an invasive grass has changed the fire frequency and suppressed the ability of the native forest to return. How an invasive nitrogen fixing tree changes the nutrient dynamics in the soil and facilitates further encroachment by other non-native plants. TERACC http://www.umaine.edu/teracc/ Terrestrial Ecosystem Response to Atmospheric Climatic Change TERACC is an international research coordination network of global change scientists that was initiated in 2001. The goals of TERACC are to: 1. Integrate and synthesize existing whole ecosystem research on ecosystem responses to individual global change drivers. 2. Foster new research on whole-ecosystem responses to the combined effects of elevated atmospheric CO2, warming, and other aspects of global change, such as changes in precipitation and increased N deposition. 3. Promote better communication and integration between empiricists, experimentalists and modelers. Through these efforts, TERRAC hopes to better integrate observational, experimental, and modeling techniques into a unified multidisciplinary approach to understanding ecosystem response to global change . LTER http://www.lternet.edu/ The Long Term Ecological Research (LTER) Network was created by the National Science Foundation (NSF) in 1980 to conduct research on ecological issues that can last decades and span huge geographical areas. UKREATE http://ukreate.defra.gov.uk/index.htm UK Research on The Eutrophication and Acidification of Terrestrial Ecosystems The UKREATE Project: The UKREATE umbrella project is funded by the Department for Environment Food and Rural Affairs (Defra) and the Natural Environment Research Council (NERC). The umbrella consists of a consortium coordinated by Prof Bridget Emmett at the Centre for Ecology and Hydrology (CEH) in Bangor, and a Defra project Officer, William Cook. The aims of the project are to: Collate dat which provide evidence for damage or recovery in a range of terrestrial habitats due to nitrogen deposition. Determine whether factors such as the form of nitrogen, grazing pressure or traits of plants present modify the impacts observed. Test proposed indicators of change in both experimental and survey settings. Clarify what determines the fate of nitrogen in soil which acts as the main sink for nitrogen. Contribute to the development of linked ecosystem model chains to forecast likelytiming responses in both soils, vegetation composition and their interdependance. Collate survey data and continue long term manipulation experiments to help test and develop model chains. Examine the potential modifying and interactive effects of climate change with the effects of nitrogen deposition. Support the UK National Focal Centre for Critical Loads Mapping. Provide knowledge transfer to a range of stakeholders and contribute to the Review of Transboundary Air Pollution (RoTAP). NutNet http://www.nutnet.umn.edu/ Nutrient Network: A Global Research Cooperative Welcome to the Nutrient Network! Two of the most pervasive human impacts on ecosystems are alteration of global nutrient budgets and changes in the abundance and identity of consumers. Fossil fuel combustion and agricultural fertilization have doubled and quintupled, respectively, global pools of nitrogen and phosphorus relative to pre-industrial levels. Concurrently, habitat loss and degradation and selective hunting and fishing disproportionately remove consumers from food webs. At the same time, humans are adding consumers to food webs for endpoints such as conservation, recreation, and agriculture, as well as accidental introductions of invasive consumer species. In spite of the global impacts of these human activities, there have been no globally coordinated experiments to quantify the general impacts on ecological systems. The Nutrient Network (NutNet) is a grassroots research effort to address these questions within a coordinated research network comprised of more than 40 grassland sites worldwide. NutNet focal research questions: How general is our current understanding of productivity-diversity relationships? To what extent are plant production and diversity co-limited by multiple nutrients in herbaceous-dominated communities? Under what conditions do grazers or fertilization control plant biomass, diversity, and composition? NutNet goals: To collect data from a broad range of sites in a consistent manner to allow direct comparisons of environment-productivity-diversity relationships among systems around the world. This is currently occurring at each site in the network and, when these data are compiled, will allow us to provide new insights into several important, unanswered questions in ecology. To implement a cross-site experiment requiring only nominal investment of time and resources by each investigator, but quantifying community and ecosystem responses in a wide range of herbaceous-dominated ecosystems (i.e., desert grasslands to arctic tundra). NutNet membership: NutNet membership is open to ecologists who are committed to either intiating a new NutNet node, collaborating with researchers at an exitisting network site, or furthering the network goals in other substantive ways. There are two primary rules of membership: You must play well with other members of the team, and You must carefully follow the research protocol for the core sampling. PrecipiNet http://precipnet.ucsc.edu/ PrecipNet is a Research Coordination Network focusing on the impacts of anthropogenic climate change precipitation timing, magnitude, and variability on biological communities, ecosystem processes, and human society. The mission of PrecipNet is to promote communication, intellectual exchange, and integration of methods and results across ecological, geographic, and disciplinary boundaries. Participants include climatologists, plant and ecosystem scientists, and social scientists. ILTER http://www.ilternet.edu/ International Long Term Ecological Research - Welcome! ILTER is a 'network of networks', a global network of research sites located in a wide array of ecosystems that can help understand environmental change across the globe. ILTER's focus is on long-term, site-based research and monitoring. ILTER’s vision is a world in which science helps prevent and solve environmental and socioecological problems ILTER can contribute to solving international ecological and socio-economic problems through question and problem-driven research, with a unique ability to design collaborative, site-based projects, compare data from a global network of sites and detect global trends. Most ILTER members are national or regional networks of scientists engaged in long-term, site-based ecological and socio-economic research (known as LTER or LTSER). They have expertise in the collection, management and analysis of long-term environmental data. Together they are responsible for creating and maintaining a large number of unique long-term datasets.

Roger del Moral Professor of Biology Dr. del Moral received his doctorate with C. H. Muller at the University of California, Santa Barbara, in 1968. He immediately joined the Botany Department at the University of Washington. Here he began a series of studies of vegetation patterns in forests and alpine sites. In 1976-1977, he spent a year in Australia at the CSIRO in Queensland and at Melbourne University. Along with David Ashton, he was the first to demonstrate that Eucalyptus inhibited native Australian shrubs in nature. His pioneering work on plant competition in stable alpine habitats was interrupted by the 1980 eruption of Mount St. Helens. He was among the first ecologists to begin study of the recovery of this volcano, studies which have produced one of the longest continuous records of primary succession now extant. In 1984, he worked on reclamation of derelict sites in the U.K. (with A. D. Bradshaw, A. Fitter and M. Chadwick), while in 1985 he was introduced to a wide variety of Japanese volcanoes (S. Kawano, H. Tagawa, M. Numata, M. Shizuoka). He has explored volcanoes in the Russian Far East with Sergei Grishin), in Sicily with Prof. Emilia Poli Marchese (during his Sabbatical), in Iceland (Hekla and Surtsey) with Dr. Borgthor Magnusson and in New Zealand with Professor Bruce Clarkson. In 2007, he published Environmental disasters, natural recovery and human responses , a general book on restoring the landscape using the lessons gained from nature . Research Interests Dr. del Moral has studied and described vegetation structure in forests, prairies, wetlands and meadows throughout Washington. His approach is deductive, rather than purely inductive, in that his projects test a priori hypotheses rather than merely describing communities. He has studied factors that control community structure in stable communities, but since 1980, his work has centered on primary succession and its relationship to restoration. Most of this work has explored the mechanisms of vegetation recovery on Mount St. Helens, but he has conducted research on several other volcanoes. A series of papers have combined long-term plot records, focused field experiments and laboratory trials to explore mechanisms of primary succession. Several bits of conventional wisdom have been modified or shown to be overly simple. Stochastic processes are very important during early succession and landscape effects, more than any other factor, dictate the nature of early species assemblages. In contrast to prevailing theory, abiotic amelioration is much more important that biotic facilitation, physical safe-sites are initially more important than nurse plant effects, refugia contribute little to the development of their surroundings, and mycorrhizae play a very limited role on volcanic succession. His studies in Japan and the Russian Far East have shown that similar processes have controlled succession on volcanoes in these regions. In Sicily, working on Mount Etna, he has found that there has been little vegetation convergence on lavas during eight centuries. In 2005, the 50th paper from his lab concerning primary succession was published. With Lars Walker of UNLV, he completed a book on the current concepts of primary succession that summarizes the historical and developing concepts surrounding how landscapes are recolonized after devastating disturbances. Widely recognized as a major synthesis of the state of knowledge in primary succession, the book has won praise from ecologists and restorationists alike. In 2007, he published a book on ecological responses to natural disasters intended for a more general public. He and Lawrence Walker hopes that this book stimulates a wider knowledge of ecological principles in the service of great quality of life. His doctoral students have also worked on a many projects. Rex Cates performed ground-breaking studies in plant-animal chemical interactions. Ted Hinds produced detailed energy budgets for cheat grass communities. The late Joy Belsky quantified environmental gradients in subalpine meadows, while Martha Cushman developed predictive models to relate vegetation structure to avalanche frequency. Virginia H. Dale modeled bumblebee foraging behavior in alpine habitats of Mount Rainier, while David Wood demonstrated that successional sequences were based on contingent factors. C. L. Huang showed how competition altered expected successional pathways. More recently, Jon Titus developed elegant experiments that demonstrated that primary succession on Mount St. Helens did NOT require mycorrhizae, while Dennis Riege demonstrated that old-field succession in the Olympic Rainforest was controlled largely by competition from introduced herbs. Chad Jones completed his study of invasions of glacier forelands in the North Cascades and Tara Fletcher Ramsey recently finished a though study of the mechanisms by which ivy invades natural vegetation. Current students are investigating several aspects of succession on Mount St. Helens. Mark Bradford http://bradfordlab.com/ Hi, you’ve reached the homepage of the Bradford lab group at Yale University’s School of Forestry Environmental Studies. Our research explores two main questions: How do plants and soil organisms respond to environmental change? How do these responses affect ecosystem function, especially the movement and storage of carbon in soils? Why focus on carbon and ecosystems? Soils and plants store huge quantities of carbon. Disturbances that degrade ecosystems release this into the atmosphere – in forms such as carbon dioxide – contributing to our changing climate. But soils and ecosystems are much more than reservoirs for carbon – their health is directly tied to water purification, flood prevention, maintenance of biodiversity, and agricultural production. Understanding how and why plants, animals, microbes and soils respond to environmental change will therefore help us understand the consequences for human well-being, and how we might manage them. We use experimental and observational approaches to investigate these effects of global change, both in the field and laboratory. We primarily work across forests and grasslands in the north and south of the eastern United States. The overall goal of our research is to provide the necessary mechanistic understanding required for reliable prediction of global change impacts on ecosystems, and their likely feedbacks to the climate system. Wilsey http://www.public.iastate.edu/~bwilsey/homepage.htm Brian J. Wilsey B.S. 1986 Henderson State University M.S. 1988 Louisiana State University Ph.D. 1995 Syracuse University Title and Mailing Address: Associate Professor, Department of Ecology, Evolution, and Organismal Biology, 253 Bessey Hall, Iowa State University, Ames, IA 50011-1020 Office: 131 Bessey Hall Lab: 40 Bessey Hall Phone: (515)294-0232 Fax: (515)294-1337 E-mail: bwilsey@iastate.edu RESEARCH INTERESTS OF THE WILSEY LAB In the Wilsey lab, we are interested in the ecology of prairie grasslands. Tallgrass prairies are among the most species-diverse ecosystems. We commonly count 20-30 plant species in Iowa within small quadrats (0.4 m2), and most small prairies ( 10 ha) support more than one hundred species ( Martin et al. 2005 , Wilsey et al. 2005a). It is still largely unknown how this very high species diversity develops and is maintained over time. Developing a better understanding of mechanisms behind diversity maintenance is a central focus of work in the lab (e.g. Wilsey et al. 2005, Polley et al. 2005, Martin and Wilsey 2006, Isbell et al. 2009, Wilsey et al. 2009). Furthermore, we are studying how changes in species diversity influence community stability and ecosystem process rates (i.e. ecosystem services).

This includes effects of climate change, elevated atmospheric carbon dioxide, other air pollutants, land use/management, fire and biotic invasion on health, biodiversity, and sustainability of forest and grassland ecosystems both in Minnesota and globally. This work simultaneously attempts to bridge the fields of physiological, community, ecosystem, landscape, and global ecology. We tend to focus on the broad ecotone of central North America, where boreal forests, northern hardwood forests, oak woodlands/savannas, and grasslands converge and mix. However, we are involved in projects that address similar themes and issues in many other biomes and geographic locations, including work in several other continents (Australia, Europe, South America). This work includes links and joint affiliation/cooperation with other groups such as the Institute on the Environment (University of Minnesota), the Cedar Creek Long-Term Ecological Research Project (University of Minnesota—National Science Foundation), the Hawkesbury Institute for the Environment (University of Western Sydney, New South Wales, Australia), the TRY Global Database Initiative (coordinated by the Max Planck Institute for Biogeochemistry, Jena, Germany) and several others ( http://forestecology.cfans.umn.edu/reich.html ). Chapin http://terrychapin.org/ F. Stuart Chapin, III (Terry) is an ecosystem ecologist whose research addresses the sustainability of ecosystems and human communities in a rapidly changing planet. This work emphasizes the impacts of climate change on Alaskan ecology, subsistence resources, and indigenous communities, as a basis for developing climate-change adaptation plans. terry.chapin@alaska.edu Professor Emeritus of Ecology Department of Biology and Wildlife Institute of Arctic Biology University of Alaska Fairbanks Office: 193 Arctic Health Phone: 1.907.474.7922 FAX: 1.907.474.6967 Home phone: 1.907.455.6408 Cleland http://labs.biology.ucsd.edu/cleland/cleland/People.html Elsa E. Cleland, Assistant Professor I study the responses of plant communities and ecosystems to global environmental changes, such as nitrogen deposition, elevated CO 2 , shifting precipitation, and invasive species. I am also interested in strategies for restoration of native plant communities in the context of present and future environmental changes. Knapp http://rydberg.biology.colostate.edu/knapplab/index.html Research in our lab focuses on plants, with a goal of understanding ecological patterns and processes from the leaf to the ecosystem level. Our research is conducted primarily in the field utilizing the comparative approach and experimental manipulations of key ecological drivers. Key areas of interest include: plant physiological ecology, ecosystems ecology, climate change, long-term ecological research, invasive plant species, restoration ecology, fire and herbivory effects on communities and ecosytems.

I investigate physiological or plant-mediated processes from the spatial scale of cells to that of whole landscapes. A recent focus of my scholarship is understanding the dynamics of climate-ecosystem interactions and their influence in coupling of carbon and water cycles in arid landscapes, which encompass ~ 40% of Earth’s surface. I am interested in the plant processes underlying these coupling and how these patterns and mechanism are related to processes in diverse biomes from around the globe. I am excited to be involved in the newest UC Reserve site - the Steele-Burnand Anza Borrego Desert Research Center. I lead the Center for Environmental Biology at the University of California, Irvine. This is an exciting program that focuses on landscape scale research that serves issues of conservation and ecosystem management. We work with the Nature Reserve of Orange County and a number of stakeholders (city, county, state, federal and non-profit groups) to bring academic research to environmental challenges. We partner with groups to focus on science literacy and public engagement using a number of programs. From 2007 to 2012 I led the UA Biosphere 2 , an interdisciplinary department in the UA College of Science. B2 serves as a center focused on research, outreach, teaching and life-long learning about Earth, its living systems and its place in the Universe. The program excels at understanding complex environmental systems using highly controlled experimental facilities, computational modeling, and observational arrays deployed in natural landscapes. This unit houses research faculty and professional staff focused on understanding how water works in the Earth system, synthesizing and incubating important topics in environmental science, and engaging a diverse stakeholder community in science, including decision makers, practitioners, K-12 educators and the public.

My current research focuses on how nutrient input and management impacts the diversity, productivity and composition of grasslands. We have established several longterm experiments to test hypotheses about how nutrient enrichment (fertilization) impacts grasslands. In one experiment (part of the KBS LTER) we have followed community response to fertilization and disturbance for over 25 years. Another set of experiments in a low-productivity grassland in SW Michigan allows us to evaluate how the scale of soil resource heterogeneity and presence of clonal species influences plant diversity and community composition. We are particularly interested in how species traits, particularly clonality and growth form, affect responses to resource enrichment. I am also interested in the consequences of diversity in managed agricultural ecosystems. On the KBS LTER project we have been monitoring the long-term effects of different crop management systems on the composition of weed communities in different crops. We have also established an experiment (the Biodiversity Experiment) in which crop type and rotation are varied to determine the impacts of rotational diversity on crop yield, weed communities and a variety of ecosystem services. Experiments and field studies established as part of the Great Lakes BioEnergy Research Center (GLBRC) at KBS are used to test hypotheses relating diversity, productivity and management practices to the sustainability of alternative biofuel crops. I am no longer advising graduate students, but maintain a research program with postdocs, undergraduates and summer interns. I am delighted to serve on graduate student committees and to support the research of non-MSU students interested in working at KBS. As Director of KBS I am promote and support a number of programs to provide undergraduates with research and educational experiences that help define and direct their career interests.

These studies have been led by scientists at Stanford University and the Carnegie Institution of Washington's Department of Global Ecology (located on the Stanford campus) with scientists from other institutions participating. Jasper Ridge Biological Preserve, which is owned and operated by Stanford University, is located on the east side of the Outer Coast Range of central California near the Stanford campus. Jasper Ridge has a Mediterranean climate with cool, wet winters and very dry summers. The Jasper Ridge global change experiments have been designed to exploit grasslands as models for understanding how ecosystems may respond to climate change. Although many experiments have been conducted to study the effects of climate change on plant species, relatively few have been done on an ecosystem scale. Jasper Ridge grassland ecosystems where chosen as model systems for several reasons. First, they are dominated by annual grasses, which have a number of advantages for these types of experiments. Annual grasses are relatively free of historical effects of climate change; their complete life cycle can be studied each year; they are small in stature making experimental design easier; and multiyear studies can potentially reveal changes in species composition over time. Second, these grasslands are rich in both species and plant functional types. Although much of the grassland at Jasper Ridge is dominated by annual grasses, other common functional types include early and late blooming annual forbs (non-grass, herbaceous plants), perennial grasses, and perennial forbs. Third, gophers frequently disturb Jasper Ridge soils, so experiments that cause moderate soil disturbance are not unrealistic in these ecosystems. Two core experimental facilities have been central to Jasper Ridge global climate change experiments. The first were the 1992-1997 Open-top Chamber Facilities, which have been almost entirely dismantled. The second is the Jasper Ridge Global Change Experiment facility, which began baseline measurements in 1997-98 and treatment manipulations in the 1998-99 growing season, and continues operating today. Both of these facilities enabled their own set of core studies as well as a number of related studies. To learn more about these studies, please explore the links shown on the left side of this page.

Pickett Download CV 2801 Sharon Turnpike; P.O. Box AB The Buell-Small Succession Study is a long term ecological study designed to document old field succession. The study was founded in 1958 by Murray Buell, Helen Buell, and John Small. It includes ten fields that were actively farmed until released for the study. Each year a team of researchers returns to the fields and measures the percent cover of plant species in permanently marked plots. By looking at how the species in the plots and their cover change over time, researchers can learn how succession progresses in the fields. Understanding the succession of the BSS fields can help researchers determine how other abandoned fields in similar systems will change over time. Because the BSS data set is extensive in space and continuous in time, it can be used to answer a wide range of additional questions. Park Grass http://www.era.rothamsted.ac.uk/index.php?area=homepage=indexdataset=1 Park Grass Experiment The Park Grass experiment is the oldest experiment on permanent grassland in the world. Started by Lawes and Gilbert in 1856, its original purpose was to investigate ways of improving the yield of hay by the application of inorganic fertilisers and organic manure. Within 2-3 years it became clear that these treatments were having a dramatic effect on the species composition of what had been a uniform sward. The continuing effects of the original treatments on species diversity and on soil function, together with later tests of liming and interactions with atmospheric inputs and climate change, has meant that Park Grass has become increasingly important to ecologists, environmentalists and soil scientists. 附: e-RA: the electronic Rothamsted Archive The electronic Rothamsted Archive (e-RA) provides a permanent managed database for secure storage of data from Rothamsted's Classical Experiments, the oldest, continuous agronomic experiments in the world. Together with the accompanying meteorological records, associated documentation and sample archive, it is a unique historical record of experiments that have been measured continuously for nearly 170 years. Users have easy access to experimental data and specialist background information on the effects of agricultural practices on soils, crops and associated ecosystems. Currently, e-RA holds records of yields and other data for the Broadbalk winter wheat, Park Grass permanent grassland, Hoosfield spring barley and Alternate Wheat and Fallow Classical experiments. Meteorological data from Rothamsted, Brooms Barn and Woburn are also available. The links, left, will lead you to background information on the experiments or the data. All Datasets shows a full list of current datasets which are continually being added to. The data in e-RA are available for scientific research, but remain the property of Rothamsted Research and the Lawes Agricultural Trust. Most of the data held within e-RA are password-protected and access is subject to our Data Access Policy . The Open Access data are available to all, no password is required, although users are required to acknowledge Rothamsted Research as the data source. The importance of e-RA, the Long-Term Experiments and Sample Archive have been recognised by the BBSRC in awarding them National Capability (NC) status. NC is defined as being a strategic component of the international research base. NCs are by definition externally facing and engaged with the user community.

There is broad acknowledgement that NCEAS has significantly altered the way ecological science is conducted, towards being more collaborative, open, integrative, relevant, and technologically informed. Different from the scientific tradition of solitary lab or fieldwork, NCEAS fosters collaborative synthesis research – assembling interdisciplinary teams to distill existing data, ideas, theories, or methods drawn from many sources, across multiple fields of inquiry, to accelerate the generation of new scientific knowledge at a broad scale. NCEAS has helped create a large community of scientists from multiple disciplines, eager to collaborate to answer some of the toughest environmental questions facing society. Through collective Working Group projects scientists share data and methods, synthesize vast amounts of information, and discover new insights and understanding to improve lives and the environment.

A present concern is how resistant organisms and ecosystems are under the rapid rate of current climate change. Changes of the ecosystems will also affect humans in many ways. However, it is not simple and straightforward to understand the effects of climate change. Since all organisms are affected by many factors, including interaction of organisms and other environmental changes, the effects of a change in climate might sometimes be counterintuitive. Human utilization of nature and this response to climate change also needs to be taken into account. The research at our department includes among other things studies on population ecological and evolutionary responses to climate change, the understanding of species distribution in relation to climate, and the effects on species interactions and whole ecosystems. We address questions related to temperature change, CO2 increase and sea-level rise.

科学研究应是在好奇心驱使下自由自在的研究 作者: 嵇少丞 人不同于动物,不能光想着什么东西好吃? 从2012年第8期“读者”杂志上读到一篇文章——《一个外国人眼中的新华字典》,开始我还不相信,后来拿出《新华字典》(商务印书馆)找出猪、牛、驴、羊、鸡的中文解释,不看不知道,一看真地吓一跳。 “猪:一种家畜, 体肥多肉,肉可食,鬃可制刷,皮可制革,粪是很好的肥料!” “牛:家畜名,力量很大,能耕田、拉车,肉和奶可食,角、皮、骨可作器物!” “驴:一种家畜,像马,比马小,耳朵和脸都较长,能驮东西、拉车、耕田、供人骑乘,皮可制阿胶。” “羊: 家畜名, 毛、皮、骨、角都可作工业上的原料,肉和乳供食用。” “鸡: 一种家畜,公鸡能报晓,母鸡能下蛋。” …… 当下大城市里的孩子,吃过很多猪肉,没看过一次猪跑。作为权威性中文字典,至少应对猪、牛、驴、羊等动物给予一定的动物学、形态学和生态学的描述,让孩子即使没有见过这些动物从今之后也能认识这些动物,不要一上来就是杀了吃肉,再把它们身体什么部位可以做成什么产品,活着的时候用来做啥劳动工具等说给孩子们听。《新华字典》这样的解释已经由来已久,反映我们中华文化十足的功利性。 一个国家最权威的字典,不应站一个屠夫或大厨的立场,对动物的描述主要就是哪个部分可以做成什么菜吃,社会上甚至还有吃啥补啥的食疗说法(猪头肉,耳丝、红烧猪蹄、炒肝尖、烀猪心、油炸肥肠、紫色血料、五香酱驴肉……),另外还强调哪些动物死后做成什么器件,实在是一个民族文化的悲哀! 似乎基于同样的文化基础,我们中国人谈生意甚至谈工作也要到饭桌上谈,不在一起吃喝,不足联络感情,无法相互信任,无法买卖产品。 有学者【见 Richard E. Nisbett: The Geography of Thought:《 思维的版图:东西方思维差异及其原因》】 做过如下心理测验:给受试人看三幅图画,分别是鸡、牛、青草,让他们将其分为两类。结果大部分中国人把牛和青草分为一类,而把鸡分到另一类;而大部分西方人把牛和鸡归为一类,而把青草分为另一类,西方人这么分类是认为,牛和鸡都是动物,而青草是植物。然而,中国人基于功利性,首先看到的是牛要吃草这个利益关系。 从这样的文化土壤,让我联想起我们中国人科学研究的驱动力。真正的科学研究是在好奇心驱使下的自由自在的研究,而不是各种功利性的驱动:职称、职务、工资、奖励、做官、院士、头衔....国内有的研究人员甚至觉得研究做好了,若不得国家级大奖、不做官、不当院士,研究就是白做了,亏了。 系统的近代科学与现代科学为什么不能诞生并蓬勃发展在中国文化的土壤上?不能不与中华文化过分的功利性有关。即使中国古人的“仰望星空”也不是真正的天文学研究,而是为皇帝观天象,为统治政治服务;中国古代道士的炼(仙)丹也不是真正意义上的化学工程与采矿冶金的研究,而是为了皇帝的长生不老,万岁万岁万万岁。就是当下中国,国家对科研的投入和实验条件都不比其他国家差,但是研究人员中又有多少不为名、不为钱、不为利、真正献身科学事业的人?许多科研人员一出了几篇国际SCI文章,就要申报各种奖励,就瞄准当院士的大目标飞奔而去。一旦为钱与名利做研究,这“研究”就掺水了,弄虚作假与浮躁吹牛就会趁虚而来。文革中科研条件那么差,中国科研人员还是做出一些国际一流的成果(例如, 青蒿素的发现、 三氧化二砷治疗白血病的发现、 哥德巴赫猜想的证明、一比 20 万地质填图,等等) , 现在条件这么好,真正的成果倒出不来, 令人深思啊。 最近,北京大学名教授陈平原先生提及王鸿飞博士几年前的一个观点: “以我在Columbia的学术标准来衡量,我所在的研究所和中国最好的大学99%的研究员教授和毕业的博士是不合格的。以美国三流大学的学术标准来衡量,中国大陆99%的研究员、教授和毕业的博士是不合格的。”陈平原写道,“让我惊讶不已的是,读科学网上的争辩文字,竟有不少人认为王文在理,只是不该说得那么透彻、那么决绝”。其实,任何不带偏见和对西方大学有足够了解的人,也都看到王鸿飞提到的问题,只是不想说出而已,当然即使不是99%,至少也有90%。然而, 正是这90%的人正在花费国家80%以上的科研经费、正是承担着中国科研与大学教学主要任务的主力军呢。 以前我曾写过一篇文章,题目是“追求真理是科学研究和高等教育的使命”,发表在海外一个华文报纸上,说的几乎是同样的问题,迄今还没过时。 追求真理是科学研究和高等教育的使命 据说,当年牛顿讲微积分,有位小商人发问道:“这学问有什么用?”,牛顿仿效古希腊最负盛名、最有影响的数学家欧几里德先前的做法,气愤地扔给他一英镑,讽刺他道:“这位先生还想从学问里找好处啊!”又过了很多年,爱因斯坦讲相对论,有位珠光宝气的富妇问:“这有什么用?”,爱因斯坦引用Benjamin Franklin的话反问道:“刚出生的婴儿有什么用?” 时至今日,那位鄙薄小商人和无知富妇关于科学的提问有时也会挂到政府官员和教育行政管理人员的口头。他们似乎只关注科学与引进人才的物质功能,完全不顾科学的内在精神价值。他们只欣赏科学之树上有实用价值的果实,为果树浇水施肥也只是为了日后采摘大批果实,而要将科学森林中暂时不结果或不以结果为目的的树木不屑一顾,或统统砍倒,这是一个可悲的事实。由此带来的严重后果就是人类再也不认为科学更崇高的使命正是在于对真理的追求。 科学家常常发牢骚:“我们这个时代是工程师和企业家的时代,绝不是真正科学家的时代。人类在进入二十一世纪之后,能满足食欲和肉欲就够了,他们用不着以追求真理为目的的科学家。现代生活追求利润和效率,真理、心灵、思想,再没人要了。” 太急功近利,势必鼠目寸光。整天直愣愣地想什么树上结什么果实,什么果实好吃,这是任何猿猴都能有的想法,只有大智的人类才会想到宇宙的起源,地球的演化,物质的组成,人为什么要活着,人类能变得更聪明吗?这类问题。所以,科学更深层的本质表现为科学研究的目的不是通常意义上那种有益于人生活得更好些,而是使人类对真理的沉思更完美,这正是人类比动物更高尚的一面。 整天直愣愣地想什么树上结什么果实,什么果实好吃,这是小松鼠都能有的想法。 加拿大有位世界著名的教授,在学科的年会上遇到几位已成名的他过去的研究生,晚上一起下馆子吃饭。大家围着桌子坐好,等了二十分钟也不见服务员送菜单来,有位高足打趣地说:“看,饭馆都不愿为我们服务了,因为我们是搞纯理论研究的科学家,一帮无用的人。”。他那低沉的声音像一片阴云掠过了餐桌。谁也没再说话,谁都在想自己作为科学家对社会有什么贡献,难道这社会真的用不着我们了?老教授看着大家一板一眼地说:“科学家是唯一能够愉快地、自觉自愿地干自己本行的人。现在就是把你们的工资消减百分之五十,你们还会选择干科研这一行,而这正是我们同时代人所缺少的。他们只是硬着头皮为了挣钱苦应付而已。假使社会上的各行各业的职工,都像科学家追求真理一样热爱自己的工作,以尽善尽美的精神做好自己的本职工作,并以此为最大的快乐,那么这个社会、这个国家、这个民族,将大有希望了。我们科学家在追求真理的过程中,既享受了乐趣,又表现了自我。” 我的一位同事说:“我死时要带上两道难题去问上帝。”。科学家在天堂里享受永生的极乐还嫌不够,还要在那里和上帝讨论科学。科学家在从事科学研究的同时,沉浸在一种与宇宙、与真理同在的激情之中。思维活动给科学家带来乐趣,而这在鄙薄的小商人和无知的二奶眼中则毫无乐趣,就如同一个太监面对三千后宫佳丽。 宇宙星辰与我们吃喝拉撒睡没关系,我们就不该研究吗? 仰望星空,人类的好奇心 笔者曾是位德国亚历山大·洪堡学者,在波茨坦爱因斯坦塔边的地球科学研究所学术度假一年。德国现代教育体制的奠基人 -- 威廉·冯·洪堡 洪堡有句名言:“大学是研究学问、追求真理的地方,而不是职业或技术培训中心,更不是卖文凭的机构。”。目前,中国大学教育的现状好像和洪堡的思想正好相反,把大学“改革”成一种新兴的产业、商业和生意,学生成为顾客,父母为他们买单,教授变成“摆地摊儿的”,教育的源头活水——“学”正在逐渐枯竭,科学终极价值的东西,在这里也正演变成找份工作的敲门砖。如此戕害教育和科学,其实不就是戕害一个伟大的民族走向世界文明前列的未来吗?

一、 ChinaAccess4EU 研讨会 自我从德国回来后,就比较关心欧盟国家的情况。今年11月1日应邀参加了在紫光国际科技交流中心召开的题为ChinaAccess4EU的研讨会,其主题是关于“支持欧盟进入中国的研究与创新项目”(Supporting the EU to access to the Chinese research innovation programmes)。据我在清华工作的小朋友讲,这次的会并不像想象中的那么成功,因为他们没能请到中国的“腕儿”级官员。虽然这个研讨会是由欧盟赞助的,但重点就是清华大学和葡萄牙创新学会(SPI)的一家咨询公司在操办。在中国的文化背景下,没有官员到场,这根本就不算是个什么会。欧洲人很讲实际,他们认为中国在对外开放的过程中,门只开了很小的缝,理应开得更大些。我对这个题目是没有兴趣的兴趣,因为这涉及到国家的大政方针,不是我们这些普通人所能定夺的。 上午的话题就是向像我们惯常开会那样,上面有人讲,下面大家听,然后提问。以前也开过这样的研讨会,曾经请来科技部的某司长,欧盟国家的人对该司长很不客气,提了若干非常直接而尖锐的问题,让该司长很难堪。我想自然会是这样,首先,司长级的官员在北京大概不少,欧盟提出的诉求绝对不是科技部一个部门能够解决的。其次,这种会又是面向企业的,那科技部就更难协调了。第三,我想司长这一级的官员恐怕更担心的是说错话而丢掉帽子。因此,科技部这回只派来了个处长,我看他讲完就走了,完全是应付一下而已。研讨会到了下午基本就没什么人了。我作为旁观者很希望了解欧盟国家为什么那么想进入中国的研究与创新项目,为什么又进不来。我下午参加了几个圆桌会议。这些圆桌也基本上是务虚的,例如,信息通讯技术;医疗和生物化学;纳米技术与新材料;清洁能源;技术转移。 这些话题都是漫无边际得大,根本就不可能在这种会议上解决。我最感兴趣的是“技术转移”因此就重点参加了这个圆桌的讨论。发现他们担心的首要问题就是害怕他们的知识产权(IPR)在华无法得到保障。那么对于企业而言,某知识产权恐怕就是他们赖以生存的命根子,尤其是对中小企业而言。在担心IPR遭到侵权的情况下,同时又抱怨中国在这方面的口子开得不大,因而陷入前怕狼,后怕虎的二难境地,使得欧盟国家的企业很难进入中国,当然也不乏成功的合作范例,但毕竟不是很多,或许有很多我不知道。其他各个圆桌似乎应该找到更加对口的单位去谈,因为这里来的都是些学者,他们对中国的企业了解不多。但他们希望了解,可是却又无法得到更准确的信息。给我的感觉是那次会议也就是浮皮潦草,没有实质上的意义 。 二、 Mobility of European Researchers to China研讨会 昨天(12月7日)我又应邀参加了在欧盟驻京办事处召开的Mobility of European Researchers to China的China Links Meeting。这次的主题是关于如何调动欧盟国家研究者的积极性,让他们来中国找到相应的资助并进行相应的研究。我倒是认为,这次会议有点儿意思。欧盟国家也面临人才的流失的问题,他们培养的学生大都流向美国、日本甚至韩国这样的发达经济体。现在他们发现,中国也是个不错的出路,而且可能未来还是不错的出路,只是他们以前没有认识到(known)。还有就是欧盟国家似乎也有一套他们的“潜规则”,就是年轻人在正式进入研究圈子之前,必须有个历练的过程,或是做博士后,或是做其他与研究相关的研究。当然那些出类拔萃者另当别论。这个“潜规则”,如果是的话,倒让我想起爱因斯坦对年轻人的忠告,大概是说,毕业之后不要急于到研究单位谋职,最好在其他地方做些工作,然后发现一下自我,看看是否是块做研究的料,最后决定是否献身科研事业。 俗话说,远来的和尚好念经。这次便请来一些远来的年轻和尚,让他们谈一下自己在中国的经历。有的成功,有的不成功。这个Workshop分为三个session。第一个是关于鼓励更多的欧盟国家的研究人员来中国做研究。这当然主要是指,年轻人。其主旨有二个,其一是获得项目资助的动力:给力的的地方;吃力的难处;未来的趋势等。其二是让欧盟国家的研究团体了解中国:是缺乏信息还是没有机会。这个session来了二位中国的相关部门的人,一位来自国家留学基金委;一位是中国自然科学基金会的,向与会者介绍了中国向国外开放的政策以及研究经费的资助等具体细节,我看与会的年轻人都听得很来劲。另外二人则是德意志学术交流中心北京办事处主任Stefan Hase-Bergen,另一位是个女孩子,Kate Woodcock是Marie Curie Fellow,来北京大学做有关心理学研究。这些都是政策层面的东西,中国讲得更加宏观,而西方人则更加微观,尤其是Dr. Woodcock,讲的就是她个人的经历。 第二个session我认为对外国人有些益处。重点讲如何让欧洲的研究人员成功到融入到中国的研究环境。包括四个方面:一、研究系统的结构与运作方式的不同;二、欧洲与中国在研究优先性上的不同;三、在研究团队中所遇到的文化差异问题;四、与想要来中国的人的支持和个人事项等。这个session请来了三位成功者,一位中国女士,来自中国科学院纳米科技中心的纳米材料与纳米安全性的生物效应实验室;专门讲了这些年该实验室与国际同行的合作,这次研讨会上只有她采用了ppt来展示该实验室的研究活动。另一位是法-中粒子物理实验室法方主任Olivier Martineau-Huynh,此人年龄也不大,但对中国颇有了解,说如果你申请一个小的,很具体的课题的话,没人会理睬你。你必须申请一个大课题,组织庞大的班底,才能说服政府掏钱。我想他这种invent a big story的办法,的确说到了点子上。但话又说回来,就是有宏大叙事,果真能弄到钱吗?最后一位是清华大学材料科学与工程系的Andry Godfrey教授。我看他倒是顺风顺水,在中国搞科研还是比较滋润。另外值得一提的是这个session的主持人David G. Evans在中国已经有15年的工作经历,虽然不能说他是中国通,但我想他一定属于外国专家局的贵宾。 最后一个session讲的内容是欧盟国家在中国继续进行研究人员的事业流向的问题。说白了,这个session讲的净是所谓的sad stories。也就是说,这些人希望在中国发展,却发现很困难。具体而言有二个方面,首先,打道回府或到其他地方去;其次,在中国克服困难并激励自己在事业上有所成就。先从年纪较大的Josef Reinhard Wählen讲,他现在供职于华为集团公关部,已做到集团的高级主管层,他就是几次转行找到了华为的,例如,最初是做研究,其次又到摩托罗拉任职,最后由于女儿来中国,才把他也带进来了。我觉得他就是面临曲折而不放弃的人之一。另外二位则不那么让人乐观,一位是国家自然科学基金委资助的前博士后人员,Cedric Larricq,来自中国商用飞机有限责任公司(COMAC),他觉得这清华的日子挺不好过,我就听他说骑车在清华转悠,我估计他要到其他地方去了。最后一位我深表同情,早在上个世纪90年代便到了中国,现在供职于德国卡尔斯鲁尔Frauhofer系统与创新研究所,是位副教授(Associate professor)。目前在中国科学院政策所负责国际合作项目的管理。她的最大一个困惑就是非常难以融入中国的科研体制中,我觉得她说的是实话,我对她提了一个问题,问她能否举例说明她的最大困难,她就是说,有一年我带着丈夫和二个孩子来中国,大家对他们全家都客客气气,吃饭时也都到他们的桌旁坐坐,然后说,“嗨,好久不见你了,最近还好吗?”然后就把她全家撂在一旁,到其他地方去应酬去了。她的挫败感很强,估计她果真要打道回府了。 欧盟这次主办的研讨会的目的达到了,至少从它设定的主旨来看。我在会上还结识了新朋友,会见了老朋友。算是有收获。研讨会之后的Buffet由欧盟驻中国办事处副主任Carmen Cano女士的良好祝愿下结束。

一个青年研究人员(25-40岁)的中科院之梦
热度 12 chenbinmse 2011-5-30 09:25
非常荣幸承蒙科学网赵总编的邀请,谈谈心中的中科院。本人没有在中科院学习或工作过,可以说完全是一个局外人,再加上自己的阅历有限,写的只是自己的一点拙见。下文若有偏颇之处,还请大家批评指正。总之,衷心祝愿中科院的未来更加辉煌! 依稀记得,我的第一次亲密认识中科院是在大四准备考研的时候。我学的专业是材料学,国内设置有该专业的大学非常多,但有此专业背景的中科院研究所却只有那么几所。我和当时班里一个非常要好的朋友一同复习考研,他选的就是我们这个专业久负盛名的中科院上海硅酸盐研究所。而我之所以和中科院失之交臂,主要是因为我想实现我从小的梦想:上清华大学。后来,我们双双如愿。就这样,初高中以及大学阶段对中科院懵懂未知的我,通过考研这件事,一下子对中科院有了初步的认识。 中科院从成立到现在,为我国科技的发展做出了杰出的贡献。展望未来,她又再为下一个更宏远的目标而奋斗。作为一名青年研究人员,我想就我的那么一点点阅历,谈谈我心中的中科院之梦。这里,我把从 25 到 40 岁之间的研究人员统称为青年研究人员,这个划分基本上囊括了一个人从刚开始读博士到最终挑起大梁的整个过程。当然啦,有些杰出的人才可能在 30 多岁就已经挑起了大梁。我选择青年研究人员作为切入点,一来自己就属于这一类,可以从自己的亲身经历来聊聊;二来,历来大家可能趋向于认为青少年就是祖国的未来,包括各国政要知名人士等的演讲也有提及,这里就不再列举了。 虽然没有在中科院学习或工作过,但我身边有很多来自中科院的朋友们,大多数也属于青年研究人员,从他们那里耳濡目染了一些有关中科院的情况。此外,我在类似于中科院的 2 个日本研究机构工作过。一个是 National Institute for Materials Science (NIMS) ,此研究机构主要做基础方面的研究;另一个是 National Institute of Advanced Industrial Science and Technology (AIST) ,此研究机构主要偏重于应用研究。因此,我就以在偏重于基础和偏重于应用的研究所的工作经历,说说我的中科院之梦。由于有些观点得益于我从朋友那里的所见所闻,所以可能部分代表了这个青年研究群体的梦想。 (a) 中科院朝着更加一流的国际声誉努力,因此 建议取消研究所前面的地名 。目前,如果中科院的研究所坐落在某个地方,习惯在研究所的前面冠个地名,如某某地方某某研究所。这样做感觉中科院研究所比较 local ,不太国际化。俗话说,人靠衣装马靠鞍。个人认为,一个好的名字应该简洁明了,其简称也容易记住。举个我们专业的世界知名的研究所, Institute for Materials Research (IMR) ,一目了然。 (b) 青少年是祖国的未来, 建议加大力度资助培养青年研究人员 。我和朋友们闲聊的时候,大家普遍认为国家是非常需要人才的,但这里所说的人才是已经功成名就的人才,如千人,百人等。诚然,每个研究所是需要这方面的杰出人才,他们可以带领某个学科方向的前进,但绝大部分实干的且正处风华正茂的还是青年研究人员们。以我曾工作过的 NIMS 为例,里面有一个研究中心 International Center for Young Scientists ( ICYS ),它专门资助一个研究人员的 early career 阶段。你可以说它是一个博士后,但与普通博后不同的是,进入 ICYS 的人员要写自己的 proposal ,有自己的项目和资金。也就是说, ICYS 的研究人员已经开始在做独立研究了,不再是简单的“打工者”呢。日本国内也有 类似资助青年研究人员的奖项: JSPS Fellowships ,资助的人数更多。大家可能听说过一些在牛实验室打过工的人,当时发表的文章很多,一旦独立工作后,反而大不如从前,这正说明了尽早培养独立研究能力的重要性。 (c) 青年研究人员的启动研究很难,因此梦想中的中科院有一个 更加公平的,大力合作的科研制度和氛围 。众所周知,青年研究人员正处在人一生中的黄金时期,但如何启动研究却是一个老大难的问题,一个显而易见的原因就是没有科研设备。很多人可能会说,赶紧加盟大老板啊,其实谁不愿意找大老板呢。关键是大老板手下从不缺人,即使暂时缺人,他那么多毕业的学生也会有巨大优势。那么,是不是建立了一个更加公平的,大力合作的科研制度和氛围就能解决问题呢?不敢说能从根本上,但至少能从一定程度上解决此问题。我以前所在的 NIMS 是这样做的:所里都有一些常见的研究设备,这类研究设备要么很贵要么非常常用,它们的一个特点就是公共的,最主要的一点就是一年的使用费可能还不到一个博后一个月的工资。举个例子来说,做材料的可能都要用到电镜来标准。我所了解的是国内做一个电镜样品就要超过一个人一个月的工资,更何况一年的使用费呢。此外,如果你要使用 NIMS 其他研究组的专业设备,也很容易促成合作的,而且这类合作可能都不用掏什么钱,最后发文章的时候把对方挂为 合作 作者。别人为什么会愿意呢?这将在下面的评价机制中说说。所以,有这么低的进入门槛,青年研究人员的启动研究就变得相对容易多了。 (d) 要保证一个公平的,好的科研合作氛围,一个 合理的评价机制 必不可少。其实,一个研究所内,绝大部分的科研设备都很齐全了,只不过是分配在不同的课题组里。个人感觉,国外做科研大多拼的是 idea ,国内拼的是如何拥有资源(设备等)。那么如何促进各课题组之间乃至跨所之间的有效合作,一个合理的良性评价机制就显得尤为重要了。我以前所在的 AIST 给我印象深刻。每发一篇文章或申请一个专利,都会评定每个作者的贡献,有多种选项,当然一种最常见的选项是第一作者多少,老板多少,剩下的贡献由其他作者均分,这样其他作者也不会在乎排名先后呢。即是说,每个作者在这样的评价体制中都会分到一杯羹。有了这样的机制,很多人也愿意合作了。另外,评定工作的重要性时,也不是按影响因子来,也不是分专业,而是分领域。就材料专业来说,常见的顶级期刊有 Nature , Science , Nano Lett , Adv Mater , Phys Rev Lett 等,一流期刊如 Appl Phys Lett , Acta Mater 等,如果按此划分的话,有的材料专业方面的领域一辈子也发不了这样的杂志。我在 AIST 的 SiC 半导体研究中心的时候,连大家很不起眼的杂志 Mater Sci Forum 都归为很重要的贡献,可能这个杂志现在连 SCI 都不收录了。 (e) 一项研究最终的是要服务社会,因此 建议加大力度和工业方面的合作 ,尤其是做偏重于应用方面的研究。我曾工作过的 AIST 的 SiC 研究中心,主要是偏重于应用研究,它在申请课题经费的时候,必须要拉到一些大公司共同来参与。这样,研究中心设计出好的参数,并不断优化,最终由大公司来做出最终的产品,最后服务于社会。这种由制度规定下的研究所和企业合作模式,既能让研究所提升研究能力,又能让企业不断升级,并最终达到服务社会大众的目的。 结合自己的经历,写了这么一点点感想,可能有些建议并不适合,但不管怎样,我们由衷的祝愿中科院越来越辉煌!

“不一样”的秘密与价值
kejidaobao 2011-3-18 15:46
文/杨书卷 “我们发现了一种名为Grb10的基因,与通常的基因表达规则不符的是,如果来自父母双方的不同,可以有完全不同的功能。”英国巴斯大学再生医学研究中心Andrew Ward所在的研究小组,发现并证明了一种基因的异常之处,这一研究成果刊登在近期出版的英国Nature杂志。 所有动物的细胞中,每个基因组都是成对出现:一条来自父亲,另一条来自母亲。同源染色体基因表达活性不同的现象,称为基因印记。多数情况下这两条基因都是活跃的,但对某些基因而言,其中一条被关闭时,基因仅能表达来自一方的同源基因,而另一方不表达。Ward的研究小组正是根据这一状况设计小鼠行为实验研究,揭示出了基因背后这条令人吃惊的“幕后花絮”。 在这项强制遭遇测试中,研究人员发现,缺乏父方Grb10基因表达的小鼠更喜欢控制其他小鼠,与脑中父方Grb10基因活跃的小鼠相比,更有可能获得同伴的“尊重”,这在哺乳动物中可是一种处于统治地位的标志。此外,这些小鼠还更有攻击性,可能扯断同笼的正常小鼠的胡须。而缺乏母方Grb10基因表达的小鼠通常会变得又大又重。 “好像是父母双方以不同的策略来帮助后代,一方致力于身体,而另一方致力于精神:即母亲的基因表达涉及胎儿成长、新陈代谢、脂肪储存,而父亲的基因表达调控着成人的社会行为。”Ward对这一现象也充满迷惑,从而激发出他下一步的探索计划:“一种基因居然能影响大脑和肌肉两个方面,这太让人惊讶了。Grb10与胚胎发育有关,对人类健康非常重要,今后我们将主要研究Grb10基因如何进化出这种双重功能。”(3月2日《科技日报》) 生命体中成千上万的基因,储存着生命孕育生长、凋亡过程的全部信息,这一“生命的密码”,在记录和传递着遗传信息,其复杂设计很多时候远远超出了我们的想象!那么,生命体中,还有哪些我们不知道的“不一样”的秘密呢? 美国德州大学西南医学中心的研究人员在2月25日出版的Science杂志上报告说,老鼠实验表明,新生哺乳动物的心脏在受损后完全能够自我愈合。现今,心脏病已成为发达国家威胁人们健康的头号杀手,这一发现为治疗人类心脏病提供了“不一样”的思路。 实验中,研究人员将刚出生1周的小鼠15%的心脏切除,结果发现,在3周内,受损的心脏重新完好地长出来,其外观和功能与正常心脏无异,而心脏中的心肌细胞是新生细胞的主要来源。 此前的研究已经证明,一些能够重新长出鳍和尾巴的鱼类和两栖类动物等低等生物,可以部分再生其受损的心脏。该研究报告作者之一、内科医学助理教授希Hesham Sadek说,“此次发现,新生哺乳动物的心脏也能够自我修复,只不过,它在发育老化的过程中‘忘记’了这一技能。”Sadek也对下一步的计划信心满满:“我们认识到,哺乳动物的心肌再生是有可能的,这使得未来将可以通过药物、基因或者其他方法以唤醒成年老鼠乃至成人的心肌再生能力。现在,我们将趁心脏仍具备再生能力时对这个短暂的‘窗口期’加以研究,并找出心脏是如何以及为什么会在生长发育的过程中‘关闭’这一非凡能力的答案。”(2月25日美国Science)。 几十年来,材料科学家试图造出一种“不一样”的金属,既能比钢坚硬,又能像塑料一样轻易被模压成各种复杂形状。现在,由Jane Schloer带领的美国耶鲁大学材料科学小组就研制出“刚柔相济”的块体金属,使这一梦想初步实现。 这种合金材料与普通金属的晶体结构不一样的是,它的原子排列没有规则,在低温低压条件下,不会像普通金属那样晶化,这样它就能像塑料一样随意塑形。该小组已造出一些具有复杂形状的物品,这些物品不到一分钟就能成形,而且比普通钢材坚硬一倍。由于实际应用的深度需求,材料科学的发展令人瞩目,许多看似“不可能完成”的任务都取得了完美的成功(2月28日美国每日科学网站)。 不过,中国科技大学地球和空间科学学院教授沈延安的关于地球历史上最大一次生命灭绝事件的原因“不一样”的研究,带给人类的则是更多的“警示”作用。 古生物化石记录表明,在过去5.4亿年,地球上共发生了5次生物大灭绝事件。其中发生在距今2.5亿年前的二叠纪末生命灭绝事件最为惨烈,造成了超过90%的海洋生物物种消失和大量陆地生物灭亡。长期以来,世界各国地球科学家对此次大灭绝事件的现象和原因莫衷一是。沈延安通过对阶段性异常的多种硫同位素研究发现,提出了新的理论模式:硫同位素异常是厌氧海水(海水中缺少氧气)的间歇性上涌造成的,而二叠纪末富集CO2的大气、厌氧海水的间歇性上涌等造成了当时地球表层环境的不断恶化,从而导致生命大灭绝。这一结论对研究现代全球气候变化具有重要启示意义:大气中CO2的不断升高有可能导致海洋缺氧,如果此类海洋环境进一步恶化,将对人类的生态环境 造成灾难性的破坏(2月22日Natural Communication)。 越来越多地知晓自然界“不一样”的秘密,就是了解其潜藏的价值,可能会带给人们巨大的惊喜;但在另一方面,也表明有更多的自然现象,其复杂性人类还无法把握。从某种意义上说,我们知道的越多,我们不知道的也就越多,因此,当人类在探索自然规律、呈现出杰出的创造性的同时,也必须对大自然保持必要的敬畏之情,这也是人类作为自然界最高智慧应有的理智态度。■
