外文翻译

五分钟搞定5000字－外文文献翻译工具大全 /node/2151在科研过程中阅读翻译外文文献是一个非常重要的环节，许多领域高水平的文献都是外文文献，借鉴一些外文文献翻译的经验是非常必要的。

由于特殊原因我翻译外文文献的机会比较多，慢慢地就发现了外文文献翻译过程中的三大利器：Google“翻译”频道、金山词霸（完整版本）和CNKI“翻译助手"。

具体操作过程如下：1.先打开金山词霸自动取词功能，然后阅读文献；2.遇到无法理解的长句时，可以交给Google处理，处理后的结果猛一看，不堪入目，可是经过大脑的再处理后句子的意思基本就明了了；3.如果通过Google仍然无法理解，感觉就是不同，那肯定是对其中某个“常用单词”理解有误，因为某些单词看似很简单，但是在文献中有特殊的意思，这时就可以通过CNKI的“翻译助手”来查询相关单词的意思，由于CNKI的单词意思都是来源与大量的文献，所以它的吻合率很高。

另外，在翻译过程中最好以“段落”或者“长句”作为翻译的基本单位，这样才不会造成“只见树木，不见森林”的误导。

注：1、Google翻译：/language_toolsgoogle，众所周知，谷歌里面的英文文献和资料还算是比较详实的。

我利用它是这样的。

一方面可以用它查询英文论文，当然这方面的帖子很多，大家可以搜索，在此不赘述。

回到我自己说的翻译上来。

下面给大家举个例子来说明如何用吧比如说“电磁感应透明效应”这个词汇你不知道他怎么翻译，首先你可以在CNKI里查中文的，根据它们的关键词中英文对照来做，一般比较准确。

在此主要是说在google里怎么知道这个翻译意思。

大家应该都有词典吧，按中国人的办法，把一个一个词分着查出来，敲到google里，你的这种翻译一般不太准，当然你需要验证是否准确了，这下看着吧，把你的那支离破碎的翻译在google里搜索，你能看到许多相关的文献或资料，大家都不是笨蛋，看看，也就能找到最精确的翻译了，纯西式的！我就是这么用的。

In traditional supply chain inventory management, orders are the only information firms exchange, but information technology now allows firms to share demand and inventory data quickly and inexpensively. We study the value of sharing these data in a model with one supplier, N identical retailers, and stationary stochastic consumer demand. There are inventory holding costs and back-order penalty costs. We compare a traditional information policy that does not use shared information with a full information policy that does exploit shared information. In a numerical study we find that supply chain costs are 2.2% lower on averagewith the full information policy than with the traditional information policy, and themaximum difference is 12.1%. We also develop a simulation-based lower bound over all feasible policies. The cost difference between the traditional information policy and the lower bound is an upper bound on the value of information sharing: In the same study, that difference is 3.4% on average, and no more than 13.8%. We contrast the value of information sharing with two other benefits of information technology, faster and cheaper order processing, which lead to shorter lead times and smaller batch sizes, respectively. In our sample, cutting lead times nearly in half reduces costs by 21% on average, and cutting batchesin half reduces costs by 22% on average. For the settings we study, we conclude that implementing information technology to accelerate and smooth the physical flow of goods through a supply chain is significantly more valuable than using information technology to expand the flow of information.Inventory management is a commercial enterprise management of the core areas, Enterprises can also achieve an effective key, if we can achieve from the purchase of stock,Sales then the entire flow of goods and capital flow situation for the unified management and reasonable production, timely sales and inventory is the smallest. reduce the backlog of material, then the business will achieve the best results.1.sessionIn my experience, session word is probably second only to the extent of the abuse of transaction, even more interesting is the transaction and the session in the context of the meaning of some of the same.session, the Chinese often translated into the session, its original meaning refers to the beginnings and ends of a series of action / information, such as a phone call from the dial to pick up the phone to hang up the middle of the process can be described as a series of session. Sometimes we can see that the case "during the session in a browser session ,...", term used here is its original meaning, is open from a browser window to close the period of ①. The most confusing is the "user (client) during the first session," the words, it may refer to a series of user actions (generally with a specific purpose related to a series of actions, such as log on to buy goods from to sign out such an online shopping checkout process, sometimes also called a transaction), but sometimes may be just that a connection could also be that the meaning of ①, the difference can only be inferred by context ②.However, when the term session is associated with the network protocol when it often implies a "connection-oriented" and / or "on hold" so the two meanings, "connection-oriented" refers to both the communication in the communication prior to first establish a communication channel, such as phone calls, until the other party answered the phone communication can begin, and this is the opposite of writing, before you sent the letter, the time you and can not confirm the other side of the address is correct, communication channels Buyi Ding can be established,but the sender, the communication has already begun. "Keep state" means the communication party is able to associate a series of messages, making messages between each other depends, for example, a waiter can recognize old customers come back and remember the last time the customer still owes a store, dollar . Examples of this type, "a TCP session" or "a POP3 session"③.And to the web server flourishing, session in the context of semantic web development has a new expansion, its meaning is mean to the client and server to maintain state between the solution ④. Session is also sometimes used to refer to such solutions, storage structures, such "stored in the session to xxx where" ⑤. For various 用于web development languages are available to some extent on the support of such a solution, so in the context of a particular language 下, session also used to denote a solution on behalf of the language, such as regular Java in the provision of javax.servlet.http.HttpSession referred to as the session ⑥.In view of this confusion has been changed, in this article use the term session will have different meanings depending on the context, drew attention to the resolution.In this article, the use of Chinese "during the browser session," to convey the meaning of ①, use "session mechanism" to convey the meaning ④, use the "session" expression meaning ⑤, use specific "HttpSession" to convey the meaning ⑥Second, HTTP protocol and the state to maintainHTTP protocol itself is stateless, HTTP protocol which is consistent with the original purpose of the client only needs a simple request to download some file server, either the client or the server not have been necessary records of past behavior to each other, and each time between the request are independent, like a customer and a vending machine or an ordinary (non-membership) as the relationship between supermarkets.However, smart (or greedy?) People soon discovered that if they can provide on-demand generation of dynamic web information will become more useful, like a cable TV with on-demand the same function. This demand on the one hand to force gradually add HTML form, script, DOM and other client-side behavior, on the other hand there is the server-side CGI practices to respond to client-side dynamic request, the HTTP protocol as the transport carrier also added a file upload , cookie these characteristics. The role which cookie is to solve the stateless HTTP protocol efforts defects. As for the subsequent emergence of the session mechanism is yet another in between the client and the server state solution.Let us use some examples to describe the session cookie and the differences and similarities between the mechanisms. I once frequented a coffee shop with free gifts to drink five cups of coffee offers a cup of coffee, but a one-time consumption of five cups of coffee is remote, then need a way to record a customer's consumption. Imagine that in fact nothing less than the following several options:1, the store's staff is very powerful, able to remember each customer's consumption, as long as customers entered the cafe, shop assistants know how to deal with the. This approach is the agreement itself to support the state.2, issue customers a card recording the number of consumers in general have a validity period. Each consumer, if this card is produced, then the consumer will be with the consumer before or after linking up. This approach is maintained in the client state.3, a membership card issued to customers, in addition to any information outside the card number is not recorded, each consumer, if the card is produced, then the records clerk in the store to find the card number corresponds to the record to add some consumer information. Thisapproach is maintained in the server-side state.As the HTTP protocol is stateless, but due to various considerations do not want to become a state, therefore, the last two programs has become a realistic option. Specifically cookie mechanism is used to maintain state of the client program, which uses a session mechanism to maintain state in the server-side program. We also see that, thanks to server-side maintain state of the program in customer client but also Xuyaobaocun a logo, so mechanisms may need the help of session cookie mechanism to identify the purpose of Da Dao saved, it actually alternatives are available.Third, the cookie mechanismThe basic principle cookie mechanism as simple as the above example, but there are several issues to resolve: "membership card" how to distribute; "membership card" of the content; and customers how to use the "Member Card."Orthodox cookie distribution is by extending the HTTP protocol to achieve, and the server through the HTTP response header with a line of special instructions to prompt the browser in accordance with the instructions generates the corresponding cookie. But pure client-side scripting such as JavaScript or VBScript can also generate the cookie.The cookie used by the browser in the background according to certain principles automatically sent to the server. Check all stored browser cookie, if a cookie is greater than or equal scope statement will be the location of the requested resources, put the resources of the HTTP request cookie attached to the head sent the request to the server. Means that McDonald's membership card can only be produced in the McDonald's store, if a store has also issued its own membership card, then enter the store when the addition to produce McDonald's membership card, but also to produce a member of the store card.cookie's contents include: name, values, expiration time, path and domain.You can specify a domain in which a domain such as. , the equivalent of main store signs, such as Procter & Gamble, you can also specify a specific domain of a machine under such or , can float Flexibility to do than.Path is the name behind the URL with the path, such as / or / foo, etc., can do more than a counter Rejoice.Path together with the domain constitutes a cookie's scope. If you do not set the expiration time, then the lifetime of this cookie to the browser during the session, simply close the browser window, cookie disappears. This period of life of the cookie browser session is called session cookie. Session cookie is generally not stored on the hard disk but kept in memory, of course, provided that it is not standardized. If you set the expiration time, the browser the cookie will be saved to the hard disk, open again after closing the browser, the cookie is still valid until the expiration time exceeds a set.Stored in a cookie on your hard disk in a different browser, shared between processes, such as the two IE windows. And stored in memory for the cookie, different browsers have different approaches. For IE, open windows in a press Ctrl-N (or from the File menu) to open the window can be shared with the original window while using other means to open the IE process will not have to open the windows shared memory cookie; for Mozilla Firefox0.8, all of the process and can share the same tab the cookie. In general is the window.open javascript window will open with the original windows shared memory cookie. Browser, this cookie for the session cookiedoes not believe that people only recognize the approach to the use of the regular session of web application development mechanism causing great distress.Here is a goolge set cookie response header exampleHTTP/1.1 302 FoundLocation: /intl/zh-CN/Set-Cookie: PREF = ID = 0565f77e132de138: NW = 1: TM = 1098082649: LM = 1098082649: S = KaeaCFPo49RiA_d8; expires = Sun, 17-Jan-2038 19:14:07 GMT; path = /; domain =. google . comContent-Type: text / htmlThis is the use of HTTPLook the HTTP Sniffer HTTP communications software to capture the part of the recordGoolge browser to access the resources again, automatically send out cookieUse Firefox can easily observe the current value of cookieUse HTTPLook with Firefox cookie can easily understand the working principle.IE can be set to ask before accepting cookieThis is a dialog box asking to accept cookie.Fourth, understand the session mechanismmechanism is a server-side session mechanism, the server uses a hash table is similar to the structure (and probably is to use a hash table) to save the information.When the program needs for a client's request to create a session when the server first checks the client's request is included in a session ID - known as the session id, if the description contains a session id for this client previously Create over session, the server in accordance with the session id to retrieve the session out of the use (if not retrieved, may be the new one), if the client request does not include session id, then create a session for this client and generate a session with this associated with the session id, session id value should be a not only will not repeat, not easy to find the law to copy the string, the session id to be returned in this response to the client saved.Save the session id of the ways to use cookie, so the interaction of the browser can automatically identify this play by the rules to the server. The name of this cookie are generally similar to SEEESIONID, and. For example, web applications weblogic generated cookie, JSESSIONID = ByOK3vjFD75aPnrF7C2HmdnV6QZcEbzWoWiBYEnLerjQ99zWpBng! -145788764, Its name is JSESSIONID.As the cookie can be artificially prohibited, there must be other mechanisms to be banned in the cookie when the session id still be able to pass back to the server. Often use a technique called URL rewriting, the session id is attached to the URL path directly behind, there are two additional ways, one is the URL path as additional information, showing the form of http:// ... .. / xxx; jsessionid = ByOK3vjFD75aPnrF7C2HmdnV6QZcEbzWoWiBYEnLerjQ99zWpBng! -145788764 The other is as a URL query string appended to the back, showing the form of http://.. (xxx)jsessionid=ByOK3vjFD75aPnrF7C2HmdnV6QZcEbzWoWiBYEnLerjQ99zWpBng!-145788764Both ways is no different for users, and only a server parsing the time to deal with the different ways, using the first ways are conducive to turning one kind of session id's information and to distinguish normal program parameters.Wei Liao Zai the interaction always maintain state, we must each client may request a path to the rear of containing this session id.Another technique known as hidden form fields. Is that the server will automatically modify the form, add a hidden field, so when the form is submitted to the session id passed back to the server. Example, the following form<form name="testform" action="/xxx"><input type="text"></ Form>Being passed to client will be rewritten before<form name="testform" action="/xxx"><input type="hidden" name="jsessionid"value="ByOK3vjFD75aPnrF7C2HmdnV6QZcEbzWoWiBYEnLerjQ99zWpBng!-145788764"><input type="text"></ Form>Application of this technology is now less, I contacted the very old iPlanet6 (SunONE Application Server's predecessor) on the use of this technology.In fact this technology can simply apply to the action URL rewriting instead.When talking about the session mechanism, often heard of such a misunderstanding, "as long as the browser is closed, session disappears." In fact, imagine the example card, unless the customer to make sales on the store card, otherwise the store would not easily remove the customer information. This is also true of the session, unless the procedure to inform the server to delete a session, otherwise the server will remain on the program are generally done in the user log off when the send a command to delete the session. However, the browser will never take the initiative to notify the server will be shut off, so the server will not have the opportunity to know the browser has been the reason why there is such a misconception, the majority of session mechanism to use a session cookie to store the session id and close your browser the session id is gone, once again connect to the server will not be able to find when the original session. If the server cookie settings are saved to the hard disk, or use some means to rewrite the browser's HTTP request header sent to the original session id sent to the server, then re-open the browser can still find the original session.It is precisely because of the closure does not cause the browser session is deleted, forcing server seesion set up a failure time, as the distance between the first use of the client session for more than the failure time, the server that the client has ceased its activities, the session will be deleted to save storage space.5, javax.servlet.http.HttpSessionHttpSession session mechanism is the Java platform implementation of norms, because it isonly the interface, specific to each web application server providers, in addition to standard support, there will still be no requirement of some norms in the nuances. Here we are with BEA's Weblogic Server8.1 as an example to demonstrate.First of all, Weblogic Server provides a set of parameters to control its HttpSession implementation, including the use of cookie switch option to use URL rewriting switches, session persistence settings, session failure time setting, as well as for the cookie a variety of settings, such as set cookie name, path, domain, cookie survival time.In general, session are stored in memory, when the process is stopped, or restart the server when the memory of the session will also be empty, if you set the session persistence feature, the server will save the session to your hard drive When the server process restart or the information can be used again, Weblogic Server supports sustainable manner including documents, databases, client-side cookie preservation and reproduction.Strictly speaking not a persistent copy saved, because the session is actually stored in memory, but the same information is replicated to each server process within the cluster, so even if a server process to stop working and still available from other processes obtain session.cookie settings will affect the survival time of the browser generates a session cookie is a cookie. The default is to use a session cookie. Interested can use it to test us in the fourth quarter, as mentioned in the misunderstanding.cookie path for the web application is a very important option, Weblogic Server on the default handling of this option makes it significantly different from other servers. We will discuss the topic later.Settings on the session reference [5] /wls/docs70/webapp/weblogic_xml.html # 10368696, HttpSession Frequently Asked Questions (In this section the implications for the session mixed ⑤and ⑥)1, session is created whenA common misconception is that the session in a client visit, was created, but the fact is that until a server-side program called HttpServletRequest.getSession (true) when such a statement is created, note that if the JSP does not appear to use <% @ page session = "false"%> closed session, the JSP file will be automatically compiled into a Servlet when the inclusion of such a statement HttpSession session = HttpServletRequest.getSession (true); This is also implied in JSP session object origin.As the session will consume memory resources, so if you do not intend to use the session, all the JSP should be turned off it.2, session is deleted whenComprehensive discussions earlier, session is deleted in the following cases a. program calls HttpSession.invalidate (); or b. from the last time before the client sends the session id than the interval session timeout settings; or c. server process is stopped (non-persistent session)3, how to do delete the browser closed session。

Transformative green marketing:Impediments and opportunitiesMichael Jay Polonsky ⁎School of Management and Marketing,Deakin University,70Elgar Road,Burwood VIC 3125,Australiaa b s t r a c ta r t i c l e i n f o Article history:Accepted 22January 2011Available online 18February 2011Keywords:Green marketingMarketing and society Sustainability Systems thinkingTransformative marketingGreen marketing is not achieving its potential for improving the quality of life of consumers,while improving the natural ecosystem.The failure is the result of the inability of consumers,firms and governments to adopt systems thinking,in which macro-marketing perspectives are integrated into their respective micro-decisions,that is,the anthropocentric view of the natural world is disregarded.The paper discusses why the three groups above have had dif ficulties in embracing environmental issues,thus impeding real transformative green marketing from occurring.To address the dif ficulties three proposed actions need to be undertaken:(1)Marketers need to look for new ways of calculating and communicating value that integrates environmental value,thereby moving away from financial measures which have no real environmental meaning.(2)Change the discourse regarding the environment,highlighting the importance of action and inaction,which needs to be based on increased education about the human –environment interface.(3)Marketing needs to refocus its emphasis on want satisfaction,shifting away from the acquisition of goods,thereby enhancing how marketers create value.Making these changes will allow marketers to operationalize transformative green marketing so the human condition and the natural system that humans operate within are both improved and bring about transformative green marketing.©2011Elsevier Inc.All rights reserved.1.IntroductionMarketing academics'and practitioners'interest in how environmental issues impact marketing activities continue to grow (Chamorro et al.,2009),but is certainly not new (Fisk,1974;Henion and Kinnear,1976).A range of marketing contexts examines the interface between the natural environment and;consumer behavior (i.e.,Diamantopoulos et al.,2003),marketing strategy (i.e.,Menon and Menon,1997),public policy initiatives (i.e.,Press and Arnould,2009)and macromarketing (i.e.,Kilbourne and Carlson,2008).Fisk (1974)suggests marketing is at least partly to blame for most of the world's environmental ills that often arise from consumption and over-consumption.Other authors suggest that marketing can assist in addressing environmental and other social problems (Sheth and Sisodia,2006).Unfortunately,much of the existing research fails to embed environmental issues as a core tenet of marketing thinking.Thus,marketing strategists often incorporate environmental considerations as an extra feature to be leveraged for competitive advantage (Ginsberg and Bloom,2004),rather than using the environment to shape strategy-improving market conditions and social welfare.Scholars de fine green marketing using a range of terms (e.g.,green marketing,ecological marketing,environmental marketing,and even responsible marketing).These de finitions have a common focus on theexchange process (i.e.,choices and decisions),with a proviso that exchange considers and minimizes environmental harm (where all parities are assumed to be aware of all potential environmental harm).Whether or not these de finitions (and associated practices)seek to improve the quality of life of the world's citizens,or improve the natural environment,remains unclear.An effective de finition of green marketing,therefore,must integrate transformative change that creates value for individuals and society,as well as for the natural environment (i.e.,environmental restoration and improvement).Thus,transforma-tive green marketing is very different from a marketing perspective that focuses on not producing societal harm,as,at present,most marketers focus on meeting human needs rather than enhancing mankind's quality of life and improving the natural environment.Marketers and society rely on nature and natural resources;nature does not rely on humanity,even though society can negatively impact on it.Therefore,mankind (and,thus,marketing)and the natural environment are interdependent.While some might debate the extent of mankind's contribution to environmental problems,if the doomsayers are correct,failure to act in the medium term will result in the inability of the ecosystem to support present day consumption,potentially eliminating marketing as presently practiced (and possibly mankind).Therefore,it is surprising that the practice of marketing (and business strategy more generally)does not explicitly integrate and address environmental issues and how they impact society (Smart,2010).In the not-so-distant past,businesses were quick to respond to less signi ficant marketing-related problems.For example,firms,consumers and governments reportedly spent hundreds of billions,if not trillions,of dollars dealing with theJournal of Business Research

January12000,computers would incorrectly believe the year was1900which would cause systems to crash.The process of greening marketing seems to be viewed with significantly less urgency on the part of most consumers,organizations and governments,even though the potential costs of inaction are much more serious and pervasive(Smart,2010;Varey,2010).Whether or not the marketing discipline(both academics and practitioners)truly understands and embraces the profound significance of environmental issues remains unclear.A number of marketing academics call for a change in thinking about marketing,in which transformative green marketing would be included. For example,early in the discipline's history Kotler and Levy(1969) suggested that there needs to be a broadening of the marketing concept. More recently,others are questioning whether marketing needs to be reformed(Sheth and Sisodia,2006).In the consumer behaviorfield, there is growing chorus of transformative consumer researchers(TCR) calling for marketing to make a positive social impact(Mick et al., forthcoming).The integration of environmental issues into marketing would extend the TCR view.For example,the Journal of Public Policy and Marketing has a forthcoming special issue focusing on TCR,and the Journal of Macromarketing recently published a special issue on sustainability,examining how marketing can assist in addressing the environmental ills faced today(Kilbourne,2010).Transformative green marketing extends this perspective incorporating environmental issues into core marketing activity,in the same way mankind is part of the natural system and not separated from the natural environment(Fisk, 1974;Smart,2010).2.The core problem:micronization of environmental issuesThe natural environment is a complex,all-encompassing system that integrates the atmosphere(air),geosphere(land),hydrosphere(water) and biosphere(all living species)(Neace,1995).Marketers understand the importance of business systems and use systems and network thinking extensively to address exchange issues,particularly in the business-to-business context(e.g.,Håkansson et al.,2009).Marketers, however,frequently ignore such broader system approaches to understand or integrate the natural environment into strategy formulation.The consideration of marketing's impact on the natural environment is often classified as macro-marketing,that is,how micro-marketing impacts society,society's influence on the broader macro-system and how systems interact(Fisk,1982).Unfortunately,academics and practitioners sometimes perceive a disconnection exists between macro-marketing and micro-marketing,which lies at the core of green marketing's inability to become transformational.The traditional micro-formation of marketing(Sheth et al.,1988)cannot easily capture environmental issues because classical micro-economics suggests that consumers(or individuals more generally)seek to maximize their own welfare(Russell and Russell,2010).Potentially,the welfare of society and the natural world is excluded unless they are embedded in individuals'values,that is,people integrate environmental issues in their decision-making because the environment is important to them. As will be described below,this perspective assumes that mankind controls their environment,which is clearly not the case.The fact that sustainability and environmental issues are generally macro-focused is at the core of the dilemma that transformational green marketing faces(van Dam and Apeldoorn,1996).How do marketers and society encourage micro-focused individuals and organizations to integrate broader macro issues and systems into their individual thinking?One might argue that this disconnection is one of the reasons why governments are forced to regulate activities to prevent distortions in the market from being exploited(Harris and Carman,1984).The lack of a macro-focus may also be why social marketers need to encourage consumers to change their behavior to create fewer negative personal impacts(Rothschild,1999),as short-term self-interest appears to outweigh the longer term benefits.For example,the classic tragedy of the commons suggests that because no-one owns the shared communal space(i.e.,the commons)no individual has an incentive to protect the shared space.Thus,the aggregation of self-interested,individualist behavior destroys the value(i.e.,the shared space)for all(Libecap,2009).As a result,some regulation of individual behavior is needed so that the commons are available in perpetuity for all users.When considering environmental issues,the tragedy of the commons is a metaphor that can be translated to consumer behavior in markets,firms within countries,or even countries within regions, as in each case,the broader ecosystem is used by all but truly controlled by none.Are humans like the elephants in Africa?When unfettered by mankind,the elephants roamed the African plains with nature keeping their numbers in check.However,when they are artificially constrained on game reserves,culling is needed to ensure they do not eat themselves into starvation(van Aarde and Jackson, 2007).The barriers relating to transformational green marketing arise from this fundamental conflict between benefits for the individual(person,firm,or nation)and benefits for society,more broadly defined as including the natural environment.The next section discusses how these economic actors'(i.e.,consumers,firms and governments)lack of a macro-focus lies at the heart of the green marketing dilemma.Then the article offers suggestions as to how marketers can possibly assist in using transformational green marketing to address the issue,and ends with some concluding remarks.3.Barriers associating with consumers,firms and governments3.1.Adopting transformative green marketingA network or stakeholder approach argues that within green marketing all economic actors are interconnected(Polonsky,1995), and the actors have the ability to facilitate or impede green marketing from becoming transformational.Marketers usually discuss the role of three main stakeholders–consumers,firms and governments–in enabling or regulating exchange processes(Fry and Polonsky,2004). The following three sub-sections seek to explain how existing(i.e., traditional)marketing perspectives inhibit the effective integration of the natural environment into marketing theory and processes,as well as identifying issues that need to be addressed for transformative green marketing to occur.3.2.ConsumersThe early green marketing research sought to better understand how to motivate consumers to behave in more responsible ways.Early authors initially placed an emphasis on motivating consumers to integrate environmental issues into their decision-making,for example, motivating people to recycle(Henion and Kinnear,1976).While macro-marketers suggested such changes in consumer orfirm behavior would lead to wider benefits to society,micro-marketers focused on whether such environmental values could be leveraged to better target new segments of consumers(Ginsberg and Bloom,2004),thereby increasing loyalty(Shrum et al.,1995),reducing price sensitivity(D'Souza et al., 2007),or improving communication(Polonsky et al.,1997).Classical economic and consumer behavior theory suggests individuals make consumption decisions that maximize their own welfare.This,however,is done within a framework in which consumers usually think of themselves as the central actor in the exchange system. In such a view,the natural environment is a resource to facilitate this satisfaction(Varey,2010)rather than a stakeholder to whom consumers are responsible(Starik,1995).Such a human-centered1312M.J.Polonsky/Journal of Business Research64(2011)1311–1319perspective(i.e.,anthropocentric)possibly arises from the religious foundations of Western society:…Be fruitful,and multiply,and replenish the earth,and subdue it: and have dominion over thefish of the sea,and over the fowl of the air,and over every living thing that moveth upon the earth.(Genesis1:28,italics added)Seeing nature as subservient to human needs inhibits consumers from taking a systems view,as man(and woman)is only one part of the natural system and,clearly,not the focal actor.As a result,leading authors such as Kilbourne and his numerous co-authors(e.g.,Kilbourne et al.,2002;Kilbourne and Carlson,2008)highlight that the core problem with consumption is the anthropocentric value system underlying the Western dominant social paradigm(DSP).This view suggests that micro-changes to consumption will be doomed to fail(or at least have a significant uphill battle)if the anthropocentric view within the DSP is not changed(Kilbourne and Polonsky,2005).Even if environmental concern could be integrated as a cornerstone of the consumer psyche,the problem may still not be solved.Consumers will act in an environmentally-responsible fashion only if they believe such actions are in their best interest.Of course,some consumer segments do already seek to act in a way that considers their impact on the natural environment.For example,increasing numbers of consumers exist who“have freely chosen a frugal,anti-consumer life-style that features low resource use and environmental impact,i.e.,they are voluntary simplifiers”(McDonald et al.,2006,p.515).Such consumers believe that value accrues to them from behaving responsibly.However,why this realization has arisen in some consumers and not others is unclear.The degree to which consumers believe environmental issues are or will become problematic,is possibly related to the disagreement regarding the causes,responses and timeframes in which remedial action must be taken.In the case of the Y2K bug,a clear deadline for the potential disaster existed–12:01AM on1January2000,and the potential disaster was prominently discussed in the business and popular media(Tewksbury et al.,2004).For environmental issues,no fixed deadlines exist and there is no media promotion(or even discussion)of the impending environmental Armageddon.In most cases,consumers believe environmental problems are somewhere in the future and,thus,are not something to worry about today.Even when consumers agree that environmental problems exist,there is no guarantee appropriate responses will occur.For example,the scientific community generally agrees that society will run out of key natural resources in the foreseeable future,such as oil.This concept has been referred to as Peak Oil and will occur when world resources of oil decline below the level needed to meet world demand(Gardi,2009).However, this has not resulted in wholesale changes in today's consumer behavior, and,in fact,dwindling oil reserves are not an issue that receives wide publicity in the press or policy debates.Consumers generally have difficulty with integrating future outcomes and consequences in their decision-making.For example, the fact that millions of people continue to take up smoking is surprising given the unequivocal evidence that smoking is bad for one's health,but consumers simply discount the future health consequences(Rindfleisch and Crockett,1999).Unfortunately for environmental marketing, researchers have found that consumers discount future environmental problems more so than other types of risk(Hendrickx and Nicolaij, 2004).Can marketers assist in making environmental problems more current and urgent in consumers'minds,thus stimulating action and providing real transformative solutions?The tragedy of the commons where all members of a community are interconnected is another issue impacting individual behavior,as consumers frequently see systems thinking(i.e.,connections amongst activities)as a barrier to behavior–How does my individual behavior impact on the wider natural system which is all encompassing?On the flip-side,a problem occurs when individuals ask–How can my individual behavior make a difference?The perceived inability to make a difference in terms of environmental problems was an early impediment to a range of environmental behaviors,including increasing recycling behavior(Scholder-Ellen et al.,1991).While attempts can be made to change the way people think about environmental issues or to enable less environmentally-harmful behavior to occur,more success might be achieved using market mechanisms that increase the pressure for individual action(i.e.,change).For example,Linderhof et al.(2001)find that when the cost of home-based waste removal is calculated on volume or weight,people reduce their waste and increase their recycling behavior.Thus,forcing increases in prices through regulation might bring about desired outcomes better than getting consumers to identify that waste is an environmental problem.While this may or may not result in an increase in underlying environmental awareness and concern,raising consumer costs may bring about the same environmental benefit(i.e.,reduced waste).Finally,one of the core tenets of consumer marketing is that marketers frequently promote ownership as a way to achieve satisfaction,but increased consumption often results in environmental problems.The perceived need to consume is further exacerbated in some sectors where technological advances mean products are considered obsolete in18months or less(e.g.,in the computer and mobile phone sectors).Marketing assumes that value is created in buyer–seller exchanges,but wanting satisfaction and the ownership of goods are not necessarily the same.Consumers can meet their needs in a variety of ways(i.e.,alternatives exist)or even modify the wants that they have,for instance by practicing voluntary simplicity(Craig-Lees and Hill,2002). Therefore,consumers do not necessarily have to own the want-satisfying goods to extract want-satisfying value.Research even suggests that one's quality of life(as measured by happiness)and increased consumption can impede sustainable development(Zidansek,2007).The increased economic importance given to the service sector is an example of how wants can be met without ownership.Opportunities exist to expand this sector beyond renting homes,furniture or appliances,to renting all types of value creation.The potential hindrance is that,in some cases,goods have an inherent value that can appreciate over time in addition to satisfying wants(i.e.,some items may become ‘rare’and collectable,and thus have value outside want satisfaction). Other goods may continue to have,primarily,a functional value(e.g.,the newest plasma television)which is not necessarily maintained through ownership of the good.Consumers'preoccupation with goods rather than the underlying want-satisfaction means increased production is required to address consumers'desire to have ready access to want-satisfying goods that they may use infrequently(i.e.,a handyman might want to own all the tools he might ever need,rather than renting or collectively sharing those used infrequently).3.3.FirmsAt the most basic level,firms are collectives of individuals that,in many ways,suffer from the aggregation of individual problems at the corporate level.Taking a neoclassical economic perspective meansfirms have a responsibility to create value for the shareholders,although many argue that broader types of performance are also important(Hillman and Keim,2001).The core issue revolves around defining the value of what is created.Marketing and management theorists propose that multi-dimensional measures of value can be developed,and this would include things such as the triple bottom line(TBL)that includes social and environmental value,in addition tofinancial value(Robins,2006).Unfortunately,afirm'sfinancial performance is still the main focus. For example,research comparing the performance of traditional and responsiblefirms still uses traditionalfinancial measures,not multi-dimensional TBL-type measures(Johnson,2003).The focus,therefore,is on how to increase thefinancial bottom line,which explains why researchers are more interested in targeting green consumers and1313M.J.Polonsky/Journal of Business Research64(2011)1311–1319extracting more value from them,than focusing solely on the societal impact of marketing.In the alternative view,green marketing becomes transformational and contributes to consumers,society and the environment.Unfortunately,profit,sales and otherfinancial/marketing measures have no relevance to the environment.Mother Nature does not have a checkbook,financial balance sheet or a demand for traditional goods and,thus,unfortunately is not represented on corporate management boards nor is nature considered in most corporate decisions.The question of how to define corporate value in a meaningful way that integratesfirms'environmental impact is less frequently discussed in research.However,some academic areas such as social accounting seek to quantify the social value offirms(Knirsch and Székely,2005). But,again,these alternatives often revert to dollar assessments that may not capture the importance of environmental issues.Other areas,such as research into stakeholder theory,have partly begun to address these multi-faceted measures as well(Hillman and Keim,2001),but they too often fall back ontofinancial measures of performance(Berman et al., 1999).Greening can be seen to createfinancial value in a number of ways,and extensive research examines how reducing harm can cut costs,reduce risk and,thus,increase the bottom line(Porter and Reinhardt,2007).Such approaches still use human-focused metrics to try and assign value to the environment(or,in reality,the costs of not looking after the environment).Marketing,as a change agent in the wider economic system,is not usually the focus of corporate or consumer activities.However, marketing innovations are bringing about significant cultural changes (good and bad).For example,birth control advances change the dynamic between males and females in society,and the Internet is changing how information is created and communicated.Thus, embracing transformative environmental marketing can serve as an organizational stimulus for innovation,thereby improving value more widely,including citizens'quality of life.Although some of the problems identified earlier,such as a lack of perceived urgency,or the fact that not all environmental costs are assigned to producers,mean corporations are not pressured to address their negative environmental impacts.Shocks to the economic system can clearly have an impact on businesses.Take,for example,the rapid innovations to increase the fuel efficiency of automobiles.The innovations have resulted in lighter automobiles;more efficient engines,alternative types of engines and fuels,systems to capture the pollution created,and even the development of alternative modes of transportation.Thus,somefirms within the transportation sector have been quick to exploit aspects of the environmental debate,although changing corporate direction needs to be a long-term strategy(Menon and Menon,1997).Unfortunately, the most recent turmoil in the US car market suggests that USfirms failed to embrace the impending environmental changes.Even when manufacturers have acted,they have not sought to redefine personal travel and the need to travel,but rather they still focus on the individual automobile to address travel options(Kadirov and Varey,2010).Of course,some would argue thatfirms are making incremental attempts to redefine the need for cars through video conferencing that allows people to meet without travel,and purchasing goods and services on the Internet,requiring fewer shopping trips.Increased public transportation alternatives also mean fewer cars are needed.Corporate and industry innovations can be more proactive and bring about environmental improvements.For example,the US-based Leadership in Energy and Environmental Design referred to as LEED building certification(US Green Building Council,2010)is designed to produce buildings that have smaller environmental footprints and lower operating costs(Muse and Plaut,2008).While still more expensive to build,as its adoption increases,economies of scale will mean that costs will drop,further increasing the benefits.All these actions are positive steps,firms still appear to be more focused on innovation and change that reduce costs,while complying with regulation or creating market value.Firms tend to be less focused on the environmental issues because of an underlying lack of value placed on responsible behavior,although examples exist of where these values are espoused(Hillman and Keim,2001).Given that businesses want to stay in business,they are more driven by economic forces than are their consumers.Unfortunately,without well-defined performance measures that incorporate non-financial benefits to the environment, businesses will be unlikely to redefine their activities,as such action would not create measurable value(even using theflawedfinancial measures available).In afirm's quest for profits,a potential problem can arise regarding the extent to which new products deliver substantive additional value to consumers,after taking into consideration the environmental impact associated with production,use and consumption.Marketers have long been criticized for producing goods that have built-in obsolescence (Guiltinan,2009)or trivial differentiation.This problem has been exacerbated by the decline in innovation cycles and rapid advancements in technology(Guiltinan,2009).For example,Moore's law suggests that computer capacity doubles every18months(Schaller,1997).While continuous product change can deliver incremental value to consumers,the question is at what environmental cost?Arefirms seeking to generate value through churn(i.e.,new purchases)or adding significant consumer value?If the latter,firms might look at how products can be designed so they can be upgraded rather than replaced.Upgradable products would,in fact,deliver additional consumer value,as consumers would be able to extract additional value from existing investments rather than purchasing extra value by buying new products.Of course, consumers would need to value upgradability rather than owning the newest product.Marketers also tend not to think about the environmental costs of replacing goods.For example,why don't all retailers of mobile phones or computers automatically incorporate trade-ins through which they can then facilitate recycling or,at the very least,provide a reverse logistics system where extraction of the value from waste products can more easily occur?Somefirms seeking to recycle components of their products have found them to be a highly valuable income stream that also reduces the environmental costs associated with producing remanufac-tured components(McConocha and Speh,1993).In some countries, governments have imposed requirements onfirms to take back unused goods or packaging from the consumers(Livingstone and Sparks,1994). However,firms seem not to have knowledge about the full life-cycle environmental impacts of their actions.In some instances(i.e.,reverse logistics)managing the life-cycle could generate income streams and,in this area,the lack of corporate systems thinking about value and environmental impacts is highlighted(i.e.,failing to recognize the interdependence of mankind,production,consumption,and the environ-mental system).Thefinal corporate issue revolves around the question of growth. Businesses want to expand their markets and profitability,but can growth occur in an environmentally sustainable fashion(van Marrewijk,2003)? This comes back to the very nature of the Western economic system. Investors want a reasonable return on their investments and,because of the competition amongstfirms for assets,those that increase their return attract more resources,and expectations for further growth are increased. Unfortunately,a value concept that is based onfinancial returns and discounts the natural environment will see the environment as a resource to exploit rather than a partner in existence.Just as service-dominant logic has emerged as a new perspective(Vargo and Lusch,2004),a need exists for an environmental dominant logic in which corporate and environmental values are intertwined.Unless the environment is given value,either as a resource or a cost to be minimized,the environment will continue to be under-considered in corporate decision-making.The impending introduction of regulated carbon abetment schemes will see this potential loophole partlyfilled because the environment(or rather pollution of the environment)will have a cost that must be addressed byfirms.However,such costs will not necessarily reflect the true value of the environment.Carbon pricing will stimulate innovation to reduce this cost,although,if carbon is1314M.J.Polonsky/Journal of Business Research64(2011)1311–1319。

Stability of hybrid system limit cycles: application to the compass gait biped RobotIan A. Hiskens'Department of Electrical and Computer EngineeringUniversity of Illinois at Urbana-ChampaignUrbana IL 61801 USAAbstractLimit cycles are common in hybrid systems. However the non-smooth dynamics of such systems makes stability analysis difficult. This paper uses recent extensions of trajectory sensitivity analysis to obtain the characteristic multipliers of non-smooth limit cycles. The stability of a limit cycle is determined by its characteristic multipliers. The concepts are illustrated using a compass gait biped robot example.1 IntroductionHybrid system are characterized by interactions between continuous (smooth) dynamics and discrete events. Such systems are common across a diverse range of application areas. Examples include power systems [l], robotics [2, 3], manufacturing [4] and air-traffic control [5]. In fact, any system where saturation limits are routinely encountered can be thought of as a hybrid system. The limits introduce discrete events which (often) have a significant influence on overall behaviour.Many hybrid systems exhibit periodic behaviour. Discrete events, such as saturation limits, can act to trap the evolving system state within a constrained region of state space. Therefore even when the underlying continuous dynamics are unstable, discrete events may induce a stable limit set. Limit cycles (periodic behaviour) are often created in this way. Other systems, such as robot motion, are naturally periodic.Limit cycles can be stable (attracting), unstable (repelling) or non-stable (saddle). The stability of periodic behaviour is determined by characteristic (or Floquet) multipliers. A periodic solution corresponds to a fixed point of a Poincare map. Stability of the periodic solution is equivalent to stability of the fixed point. The characteristic multipliers are the eigenvalues of the Poincare map linearized about the fixed point. Section 4 reviews the connection between this linearized map and trajectory sensitivities.Poincare maps have been used to analyse the stability of limit cycles in various forms of hybrid systems. However calculation of the underlying trajectory sensitivities has relied upon particular system structures, see for example [7, 8], or numerical differencing, for example [6]. This paper uses a recent generalization of trajectory sensitivity analysis [9] to efficiently detemine the stability of limit cycles in hybrid systems.A hybrid system model is given in Section 2. Section 3 develops the associated variational equations. This is followed in Section 4 by a review of stability analysis of limit cycles. Conclusions and extensions are presented in Section 5.2 ModelDeterministic hybrid systems can be represented by a model that is adapted from a differential-algebraic (DAE) structure. Events are incorporated via impulsive action and switching of algebraic equations, giving the Impulsive Switched (DAIS) modelwheren x R ∈ are dynamic states and my R ∈ are algebraic states;(.)δ is the Dirac delta;(.)u is the unit-step function;,:n mnj f h RR +→；(0)(),:i n mng gR R ±+→; some elements of each(.)gwill usually be identicallyzero, but no elements of the composite g should be identically zero; the()i g± aredefined with the same form as g in (2), resulting in a recursive structure for g;,dey yare selected elements of y that trigger algebraic switching and state reset(impulsive) events respectively;dyandeymay share common elements.The impulse and unit-step terms of the DAIS model can be expressed in alternative forms:Each impulse term of the summation in (1) can be expressed in the state reset formwhere the notation x+denotes the value of x just after the reset event, whilstx-andy-refer to the values of x and y just prior to the event.The contribution of each()i g± in (2) can be expressed aswith (2) becomingThis form is often more intuitive than (2).It can be convenient to establish the partitionswherex -are the continuous dynamic states, for example generator angles, velocities andfluxes;z are discrete dynamic states, such as transformer tap positions and protection relay logic states;λ are parameters such as generator reactances, controller gains and switching times. The partitioning of the differential equations f ensures that away from events,x -evolves according to .(,)x y f x --=, whilst z and λ remain constant. Similarly,the partitioning of the reset equationsjhensures thatx -and λ remain constantat reset events, but the dynamic states z are reset to new values given by(,)jh y x z--+=-. The model can capture complex behaviour, from hysteresis and non-windup limits through to rule-based systems [l]. A more extensive presentation of this model is given in [9].Away from events, system dynamics evolve smoothly according to the familiardifferential-algebraic modelwhere g is composed of(0)gtogether with appropriate choices of()i g- or()i g+ ,depending on the signs of the corresponding elements of yd. At switching events (2),some component equations of g change. To satisfy the new g = 0 equation, algebraic variables y may undergo a step change. Reset events (3) force a discrete change in elements of x. Algebraic variables may also step at a reset event to ensure g= 0 is satisfied with the altered values of x. The flows of and y are defined respectively aswhere x(t) and y(t) satisfy (l),(2), along with initial conditions,3 'Ikajectory SensitivitiesSensitivity of the flowsxφandyφto initial conditionsxare obtained bylinearizing (8),(9) about the nominal trajectory,The time-varying partial derivative matrices given in (12),(13) are known as trajectory sensitiuities, and can be expressed in the alternative formsThe formxx ,xy provides clearer insights into the development of thevariational equations describing the evolution of the sensitivities. The alternative form 0(,)x t x φ, 0(,)yt x φ highlights the connection between the sensitivities and the associated flows. It is shown in Section 4 that these sensitivities underlie the linearization of the Poincare map, and so play a major role in determining the stability of periodic solutions.Away from events, where system dynamics evolve smoothly, trajectory sensitivities 0xx andxy are obtained by differentiating (6),(7) withrespect to 0x.This giveswhere/xf x f≡∂∂, and likewise for the other Jacobian matrices. Note that,,,xyxyf fg gare evaluated along the trajectory, and hence are time varyingmatrices. It is shown in 19, 101 that the numerical solution of this(potentially high order) DAE system can be obtained as a by-product of numerically integrating the original DAE system (6),(7). The extra computational cost is minimal. Initial conditions forxx are obtained from (10) aswhere I is the identity matrix. Initial conditions for 0zy follow directly from(17),Equations (16),(17) describe the evolution of the sensitivitiesxx andxybetween events. However at an event, the sensitivities are generally discontinuous. It is necessary to calculate jump conditions describing the step change inxx andxy . For clarity, consider a single switching/reset event, so the model (1),(2) reduces(effectively) to the formLet （(),()x y ττ） be the point where the trajectory encounters the triggering hypersurface s(x,y) = 0, i.e., the point where an event is initiated. This point is called the junction point and r is the junction time. It is assumed the encounter is transversal.Just prior to event triggering, at time τ-, we haveSimilarly,,y x++are defined for time τ+, just after the event has occurred. It isshown in [9] that the jump conditions for the sensitivitiesxx are given byThe assumption that the trajectory and triggering hypersurface meet transversally ensures a non-zero denominator for 0x τ The sensitivitiesxy . immediatelyafter the event are given byFollowing the event, i.e., for t τ+>, calculation of the sensitivities proceeds according to (16),(17) until the next event is encountered. The jump conditions provide the initial conditions for the post-event calculations.4 Limit Cycle AnalysisStability of limit cycles can be determined using Poincare maps [11, 12]. This section provides a brief review of these concepts, and establishes the connection with trajectory sensitivities.A Poincark map effectively samples the flow of a periodic system once every period. The concept is illustrated in Figure 1. If the limit cycle is stable, oscillations approach the limit cycle over time. The samples provided by the corresponding Poincare map approach a fixed point. A non-stable limit cycle results in divergent oscillations. For such a case the samples of the Poincare map diverge.To define a Poincare map, consider the limit cycle Γshown in Figure 1. Let ∑ be a hyperplane transversal to Γ at*x. The trajectory emanating from*xwill again encounter ∑ at*xafter T seconds, where T is the minimum period of the limit cycle. Due to the continuity of the flowxφwith respect to initial conditions, trajectories starting on ∑ in a neighbourhood of*x. will, in approximately T seconds, intersect ∑ in the vicinity of*x. Hencexφand ∑define a mappingwhere()kT x ττ≈ is the time taken for the trajectory to return to ∑. Complete details can hefound in [11,12]. Stability of the Paincare map (22) is determined by linearizing P at the fixed point*x, i.e.,From the definition of P(z) given by (22), it follows that DP(*x) is closely related to thetrajectory sensitivities***(,)(,)xxT T x x xφφ∂≡∂. In fact, it is shown in [11] thatwhereσ is a vector normal to ∑.The matrix*(,)xT x φis exactly the trajectory sensitivity matrix after one period of the limitcycle, i.e., starting from*xand returning to*x. This matrix is called the Monodromymatrix .It is shown in [11] that for an autonomous system, one eigenvalue of *(,)xT x φ isalways 1, and the corresponding eigenvector lies along **(,)f y x The remaining eigenvalues*(,)xT x φof coincide with the eigenvalues of DP(*x ), and are known as the characteristicmultipliers mi of the periodic solution. The characteristic multipliers are independent of the choice of cross-section ∑ . Therefore, for hybrid systems, it is often convenient to choose ∑ as a triggering hypersurface corresponding to a switching or reset event that occurs along the periodic solution.Because the characteristic multipliers mi are the eigenvalues of the linear map DP(x*), they determine the stability of the Poincarb map P(kx), and hence the stability of the periodic solution.Three cases are of importance: 1. Alli m lie within the unit circle, i.e., 1im<,i ∀.The map is stable, so the periodicsolution is stable. 2. Allim lie outside the unit circle. The periodic solution is unstable.3. Someim lie outside the unit circle. The periodic solution is non-stable.Interestingly, there exists a particular cross-section*∑, such thatwhere *ς∈∑.This cross-section*∑is the hyperplane spanned by the n - 1 eigenvectors of*(,)xT x φthat are not aligned with **(,)f y x . Therefore the vector *σthat is normal to*∑ is the left eigenvector of *(,)xT x φ corresponding to the eigenvalue 1. The hyperplane*∑is invariant under*(,)xT x φ, i.e., **(,)f y x maps vectors *ς∈∑back into*∑.5 ConclusionsHybrid systems frequently exhibit periodic behaviour. However the non-smooth nature of such systems complicates stability analysis. Those complications have been addressed in this paper throughapplication of a generalization of trajectory sensitivity analysis. Deterministic hybrid systems can be represented by a set ofdifferential-algebraic equations, modified to incorporate impulse (state reset) action and constraint switching. The associated variational equations establish jump conditions that describe the evolution of sensitivities through events. These equations provide insights into expansion/contraction effects at events. This is a focus of future research.Standard Poincar6 map results extend naturally to hybrid systems. The Monodromy matrix is obtained by evaluating trajectory sensitivities over one period of the (possibly non-smooth) cyclical behaviour. One eigenvalue of this matrix is always unity.

外文原文 1Building Materials Selection and SpecificationFae'q A. A. RadwanFaculty of Engineering, Near East University, KKTC, Lefkosa, Mersin 10, TurkeyAbstract: The limitations in the selection of the building materials and to the sustainability of any building construction materials that can be used are presented. The practices and techniques that can be used in reducing and minimizing the environmental impacts of building are discussed. Recommendations of using secondary and recycled materials in the construction of buildings are given. Framework for methods of assessment of the sustainability in building construction for environmental performance is presented.Key Words: Limitations, sustainability, environmental impacts, framework, climate.1. IntroductionThere is an apparently unbounded range of possibilities for the selection of building materials for the construction of structures of almost any shape or stature. Its quality will affect the structure function and long life, and requirements may differ with climate, soil, site size, and with the experience and knowledge of the designer. The factors that have the most outstanding solutions are impermeability, control of heat, air, and water flow, and the stability of the structure [1-3].Raw materials extraction, manufacturing processes, and the transportation of the materials to the project site have a multitude of impacts on the environment. These include the disruption of habitats and ecological systems, use of water, and, through energy use, the emissions of air pollutants and climate change gases. Building materials also have major impacts on the building occupants manufacture, construction of buildings and the use of building materials make a significant environmental impact internally, locally and globally. But it is not easy to deliver information to make adequate inclusion decisions considering the whole life cycle of a building. Decisions on sustainable building integrate a number of strategies during the design, construction and operation of building projects. Selection of sustainable building materials represents an important strategy in the design of a building.2.SustainabilityIn recent years, the concept of sustainability has been the subject of much disputation by academics and professionals alike. In 1987, the World Conference on Environment and Development defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs (WCED, 1987).Sustainability must address ecological impacts, regardless of conflicting interpretations of the WCED definition.A good sustainable product must give as much satisfaction as possible for the user. If not, it will be unsuccessful on the market and an economic failure.It is also important to inform people as to what basis a certain product is considered to be sustainable or not and why they should buy it [4- 5].When developing a new product, it is illustrative to move between the three corners Ecology, Equity and Economy in order to obtain a suitable balance so that each category can be fulfilled in the best way.·Ecology (environmental protection).·Equity (social equity).·Economy (economic growth).2.1 Materials Selection and SustainabilityAmong the notable technological developments of the 20th century has been the development of tens of thousands of new materials for use in construction and engineering. The construction industry has also grown to the point where it is a very large consumer of energy and materials. Concern for the environment and the impact of human activity on the Earth's ecological systems has now become clear sighted.We are faced with the problems of material selection and the environmental consequences of their use. Environmentalists have proposed various methods for assessing the impact of materials and energy use, these include ecological foot printing, ecological rucksacks, embodied energy and carbon dioxide values, and so on. Engineers have put forward rational selection methods for the choice of materials. These techniques will be reviewed and explored in an attempt to provide an environmentally-aware, materials selection method- logy for use in construction.Strictly, the term sustainable means that something is capable of being sustained not for an hour, or a day, or a week, month or year, but indefinitely.The implication is that if some process which uses materials and energy is described as sustainable, then the materials and energy which are consumed arecapable of being replaced by natural or other processes as fast as they are consumed. In many cases materials and energy appear to be consumed at a faster rate than they are being replaced. However, to make a judgment, we would need to know what the respective supply and consumption rates are in other words we need some quantitative or numerical index to help us [2].2.2 Environmental CriteriaSince construction uses such large quantities of materials, it has a major impact on the environment. In order to assess and evaluate such impact, a number of criteria or indices have been devised by economists, engineers and environmentalists, and the more important of these are the following [2].2.2.1 Embodied EnergyThis is quite simply the amount of energy consumed in manufacturing a unit quantity of a material, and it is usually expressed in kJ/kg. Its value is determined by the efficiency of the manufacturing plant. Values range from 275 GJ/tonne for aluminum (a high value) to 0.1 GJ/tonne for gravel aggregates (a low value) [2].2.2.2 Embodied Carbon DioxideEmbodied C02 is similar to embodied energy. It is the weight of C02 emitted during manufacture of unit weight of the material, and is usually expressed as kg of C02 per ton.Again, the value will depend upon the efficiency of the manufacturing plant [2].2.2.3 Ecological RucksackThe ecological rucksack concept was devised as a way of assessing material efficiency by F. Schmidt一Bleek [6]. He recognized that many tonnes of raw material could be extracted and processed to make just one kilogram of material. For example, the environmental rucksack for the precious metal platinum is 250,000:1.2.3 Rational Selection MethodThere are various approaches to the problem of selecting materials from the huge numbers now available. Designers can have recourse to materials property charts and data books. Alternatively, they can talk to their colleagues, hoping that by widening the knowledge circle, they will not omit a significant group of materials. Another strategy is simply to specify the same or a similar material to those used in previous, similar designs. All these are valid approaches, but they may result in the specification of a less than ideal material and overall, a less than optimal solution to the problem [3-5].The basis of the rational selection methods devised to date is a recognition that the performance of a component, artifact or structure is limited by the properties of the materials from which it is made. It will be rare for the performance of the item to depend solely on one material property; in nearly all cases, it is a combination of properties, which is important. To give an example, in lightweight design, strength to weight ratio of, and stiffness to weight ratio E/pwill be important. Ref. [3] has put forward the idea of plotting material properties against each other to produce material property maps. On these maps, each class of material occupies a field in material property space, and sub-fields map the space occupied by individual materials.These materials property charts are very information-rich they carry a large amount of information in a compact but accessible form. Interestingly, they reveal correlations between material properties, which can help in checking and estimating data, and they can also be used in performance optimization, in a manner such as that set out as follow.If we consider the complete range of materials, it immediately becomes apparent that for each property of an engineering material there is a characteristic range of values, and this range can be very large. For example, consider stiffness (Young's Modulus E). Materials range from jelly (very low stiffness) up to diamond (very high stiffness). The properties can span five decades (orders of magnitude),A number of conclusions can be drawn, including:(1) A rational selection method such the one put forward by Ashby is capable of incorporating environmental parameters such as embodied energy and C02 or the environmental rucksack concepts, thereby making possible rational selections based on environmental considerations.(2) This method is not as simple to use as the environmental preference method or the environmental profiles method. However, this rational method could be used to generate data for the environmental profiles and preference methods.(3) The construction industry needs to take steps to better integrate itself into the materials cycle. The quantity of demolition waste needs to be reduced, and more of it should be recycled. To this end, the building designers need to keep full records of materials of construction, and buildings need to be designed for easy dismantling at the end of their useful lives.2. 4 Ashby's Materials Selection MethodologyMaterials selection charts一Property interaction (not always causal)一First order optimization●Performance indices●Multiple constrains●Multiple design goals●Shape and material interaction一“Enhanced" performance indicesProcess selection [3, 4].3. Foundations and Construction ComponentIn any consideration of which building materials and alternatives can feasibly be integrated into the foundations of a large-scale development there are several limitations that must be considered.In terms of the actual materials that may be used, there are three main limitations. First, because of the large scale and heavy loads that the foundations must support, strength is imperative. Any materials must be consistently strong and able to effectively distribute the weight of the structure. The second major limitation is climate. In areas with sub-zero winter conditions, frost heave is a major consideration. For this reason, foundations must be deep enough to support the structure despite any changes in near-surface volume; shallow foundations will be insufficient unless certain innovative steps are taken. The limitation of climate also influences any decision on insulating foundations. Finally, there is the consideration of cost. This consideration is reliant on material availability, cost per unit, and building techniques and associated labor. For these reasons, the only materials that can feasibly be used are concrete and steel. Therefore, the alternatives for minimizing impact lie more in the methods of construction and any realistic structural changes that can be made.The three main foundation components of concrete, steel, and insulation will be examined as the only reasonable materials for the construction of a building with limitations such as the foundations [1].3.1 ConcreteIt is the fundamental component of the foundation construction, receiving the building loads through walls or posts and distributes them down and outwards through the footings. Concrete and cement have ecological advantages which include durability, long life, heat storage capability, and (in general) chemical inertness [8].The life cycle concerns of concrete are as follows. First, there is land and habitat loss from mining activities. Furthermore, the quality of both air and water quality suffer from the acquisition, transportation, and manufacture. Carbon dioxide emissions are also a negative environmental impact accrued through the production and use of concrete. Similarly, dust and particulate are emitted at most stages of the concrete life-cycle. $oth carbon dioxide and particulate matter have negative impacts on air quality [1]. Water pollution is also another concern associated with the production of concrete at the production phase. Fly ash is by-product of the energy production from coal-fired plants and increasing its proportion in cement is environmentally beneficial in two ways. First, it helps in reducing the amount of solid waste which requires disposal. As well, fly ash in the cement mixture reduced the overall energy use by changing the consistency of the concrete. Fly ash, increases concrete strength, improves sulfate foundation, decreases permeability, reduced the water ratio required, and improves the pump ability and workability of the concrete [9]. Now in the United States, the Environmental Protection Agency requires that all buildings that receive federa funding contain fly ash and most concrete producer: have access to this industrial waste [9].There are alternative methods of both making concrete and building foundations with this concrete that have environmental benefits, no matter the structure scale or climate. These include Autoclaved Aerated Concrete, the increased integration of fly ash into the cement mixture, and the use of pre-cast foundation systems to reduce resource use. Through consideration and possible integration of these alternatives, impacts could potentially be reduced.3.2 SteelAs wood resources are becoming limited, steel is increasingly popular with builders. In the case of a large-scale building, steel reinforcement is basically a necessity for overall strength and weight distribution.The initial life cycle impacts of steel use are similar to those of concrete. These include land and habitat loss from mining activities, and air and water quality degradation from materials acquisition and manufacture [1]. However, the largest proportion of steel used nowadays contains a percentage of recycled materials. In terms of improving environmental conditions by reducing impacts, this is the only real recommendation for the use of steel in building foundations; to purchase recycled steel products. Not only would this reduce industrial and commercial solid waste,such a decision would also reward the manufacturers of such products.3. 3 InsulationNew and innovative pre-cast building foundations are becoming increasingly available and feasible for implementation. These new systems can reduce the overall raw material use, as well as conserve energy through the creation of an efficient building envelope. A further used of this rigid insulation as a skirt around the building foundations helps to eliminate any potential frost problems, improve drainage, and help further reduce heat loss. A polyethylene air and water vapor barrier is applied above the insulating layer, as is a three to four inch layer of sand. These shallow foundation systems have excellent insulating properties, decreased use of raw materials for concrete, and comparatively low demands for labor. However, the use of rigid insulation is increased. Also, in soils where frost and drainage is a consideration additional piles in the centre of the foundation may be required to prevent movement. This increases the relative land disturbance, although it remains still much less than that of deep foundation systems. Shallow foundations are structurally sound and are becoming increasingly common in colder climates. There are strength considerations associated with these new techniques which must be addressed by someone with the technical ability to do so, before they can be feasibly recommended for the building of the new residence.As discussed above, there are limitations to the sustainability of any foundation construction materials used. In other words, there are environmental impacts associated with all types of foundations. For these reasons, a primary recommendation is the use of secondary materials (fly ash and recycled steel) in the construction of foundations.4. FrameworkThe material components of the building envelope, that is, the foundation, wall construction, insulation and roof, have been analyzed within a framework of primarily qualitative criteria that aim to evaluate the sustainability of alternate materials relative to the materials cited in the current foundation design. This analytical process has enabled the identification of several construction materials that can be feasibly integrated into current design and construction standards of the building envelope.The tools and strategies described below are useful in analyzing the relative benefits of different materials[9-14].Life-Cycle Assessment (LCA). LCA is a comprehensive analysis that takes intoconsideration all aspects of a material over its entire lifetime: raw materials extraction; manufacturing and processing; transport; use; and post-use recycling, reuse, or disposal. This approach enables a true "apples to apples" comparison between materials.The BEES system (Building for Environmental and Economic Sustainability) developed by the National Institute of Standards and Technology is the most widely used methodology. BEES provides materials with a score that can be compared to other similar products. At this time, however, a fairly limited number of materials have completed the BEES analysis.Life-Cycle Costing. Life-Cycle Costing is an analysis of the short- and long-term costs associated with a material, from purchase to ultimate recycling or disposal. This includes frequency of replacement, maintenance costs, and costs that are avoided through use of the material (or system). LCC is useful in looking beyond a comparison based solely on first costs. Similar to LCA, this type of analysis is not available for all materials, but a back-of-the-envelope calculation is usually fairly easy to work up.Certification. Many conventional building products are approved or certified by independent third party or government groups. The Forest Stewardship Council certifies the certifiers (Smart Wood and SCS) that assess whether forestry companies are using sustainable management practices to harvest wood. The Carpet and Rug Institute provides a Green Label for carpets that meet certain low-VOC criteria. Green Guard certifies products that meet strict indoor air quality criteria. The Department of Energy's Energy Star label identifies equipment and appliances that meet or exceed standards for energy efficiency. Scientific Certification Systems and Green Seal certify recycled-content claims and other green product claims made by manufacturers.5. ConclusionOver-consumption, resource utilization, pollution and over-population are examples of the perhaps most basic problems for the environment in the future. A more sustainable future can be achieved by producing more sustainable products causing less environmental impact. Materials and design are and will always be very important areas when developing more sustainable products.The Life Cycle Assessment concept might be the most effective way of determining the environmental impacts for all product stages from extract of material to the product disposal stage. A price must be set for restoration on everyenvironmental impact. Information can be received from official authorities pertaining to the environment in different countries. Renewable and easy recyclable materials are preferably used together with a design for easy recycling and repair of the products. Minimization of the energy connected to the product is also important. Full sustainability can never be achieved for products according to thermodynamic laws. However, the attempt to achieve more sustainability is a requisite if we want to preserve the earth for the coming generations. Education, research and spreading of information will be very important for the future in order to receive more sustainable products especially because the market demand is important in order to develop successful sustainable products.References[1] M.
