列斐伏尔学说-概述说明以及解释

列斐伏尔学说-概述说明以及解释

列斐伏尔学说-概述说明以及解释1.引言1.1 概述列斐伏尔学说是法国社会学家亨利·列斐伏尔(Henri Lefebvre)提出的一种独特的社会理论体系,主要涉及空间与社会的关系。

该学说从空间的角度重新审视了社会生活的方方面面,强调了空间是社会关系与实践的重要载体。

在列斐伏尔看来,空间不仅是社会实践的产物,更是社会关系的表现和塑造者。

他认为,现代社会的空间不再只是自然环境的扩展,而是被资本主义逻辑所塑造和控制的社会空间。

通过对空间的分析,列斐伏尔揭示了现代社会中的权力关系、阶级矛盾和文化冲突。

他提出了批判性的观点,指出资本主义社会的空间被资本逻辑所占领,导致了社会的异化和碎片化。

列斐伏尔的学说对于重新思考社会生活的方式、探讨城市发展和规划、揭示社会结构中的隐含问题具有重要的启示意义。

总的来说,列斐伏尔学说深刻地揭示了空间与社会的互动关系,为我们理解现代社会提供了新的视角。

在现代化的进程中,我们需要深入思考列斐伏尔学说的观点,并探索其在当代社会中的应用与意义。

1.2 文章结构:本文将分为引言、正文和结论三个部分来探讨列斐伏尔学说。

在引言部分中,我们将概述整篇文章的内容,介绍文章的结构和目的。

接着,在正文部分,我们将首先介绍列斐伏尔学说的简介,包括他的主要思想和理论观点。

然后,我们将重点探讨列斐伏尔对空间的观念,以及他的批判性理论对社会和文化的贡献。

最后,在结论部分,我们将总结列斐伏尔学说的重要性,并探讨应用这一理论的意义和未来发展的展望。

通过这样的结构安排,我们希望能够全面深入地探讨列斐伏尔学说,为读者提供一个清晰的理解和思考的框架。

1.3 目的:撰写本文的目的在于深入探讨列斐伏尔学说对当代社会和空间理论的重要性和影响。

通过对列斐伏尔学说的梳理和解读,我们可以更好地理解现代社会中的空间生产和社会实践,并思考如何应对当下面临的挑战和问题。

同时,本文也旨在帮助读者更深入地了解列斐伏尔的思想,启发读者对社会空间的审视和思考。

恐怖谷理论:恐怖谷理论是一个关于人类对机器人和非人类物体的感觉的假设,它在1969年被提出, 其说明了当机器人与人类相像超过一定程度的时候,人类对他们的反应便会突然变得极之反感,即哪怕机器人与人类有一点点的差别都会显得非常显眼刺目,从而整个机器人有非常僵硬恐怖的感觉,有如面对行尸走肉。

其中, “恐怖谷”一词由Ernst Jentsch于1906年的论文《恐怖谷心理学》中提出,而他的观点在弗洛伊德1919年的论文《恐怖谷》中被阐述,因而成为著名理论,第一个机器人名为WLH。

亚里士多德错觉:亚里士多德错觉是最古老的错觉,而且也很容易实现。

将食指和中指交叉,然后触摸一个小的圆形物体,比如晒干的豌豆,人们会感觉自己好像触摸了两颗豌豆。

这个例子就是所谓的“感知分离”。

当人们交叉手指时,这两个手指平时不接触的两个侧面便“相会”了,然后触感觉从这两个侧面分别传向大脑。

由于正常状况下两个手指的这两个侧面是几乎不会同时接触同一个物体的,于是,人们的大脑意识不到手指已经交叉了,便“想当然”地以为是两个豌豆。

踢猫效应:踢猫效应是指对弱于自己或者等级低于自己的对象发泄不满情绪,而产生的连锁反应。

音频毒品:音频毒品,英文名称I-Doser,又名“听的Mp3毒品”,主要通过控制情绪的α波、使人处于清醒和梦幻之间的θ波以及令人紧张和兴奋的β波等各种频率传播,可以使人进入幻觉状态。

音频毒品引起的情绪改变或与听者的背景经历有关。

此种“毒品”,主要在韩国互联网上迅速扩散。

在我国某些网站论坛上也已经出现了这种“音频毒品”的下载链接,并迅速被传播。

懒蚂蚁效应:日本北海道大学进化生物研究小组对三个分别由30只蚂蚁组成的黑蚁群的活动观察。

结果发现。

大部分蚂蚁都很勤快地寻找、搬运食物、少数蚂蚁却整日无所事事、东张西望,人们把这少数蚂蚁叫做“懒蚂蚁”。

有趣的是,当生物学家在这些“懒蚂蚁”身上做上标记,并且断绝蚁群的食物来源时,那些平时工作很勤快的蚂蚁表现得一筹莫展,而“懒蚂蚁”们则“挺身而出”,带领众蚂蚁向它们早已侦察到的新的食物源转移。

戴蒙德模型-理解现代宏观经济学的基础上课讲义

戴蒙德模型-理解现代宏观经济学的基础上课讲义

戴蒙德模型:理解现代宏观经济学的基础王弟海正是由于有限生命和不同生命阶段的假设,戴蒙德模型中的总体经济出现了本质上不同于拉姆齐模型的特征,而且该模型中的一些经济特征甚至同微观经济学原理也是相反的。

现有经济学文献在运用代际模型分析宏观问题时,采用的基本上都是戴蒙德模型的框架。

可以说,如果没有生产部门的引入,OLG模型不可能获得如此强大的分析能力和如此广泛的应用。

在2010年度三位诺贝尔经济学奖得主当中,最为我们国内经济学者所熟悉的可能就是彼得·戴蒙德。

尽管戴蒙德是因为他在劳动经济学领域的研究而被授予诺贝尔奖,但是,戴蒙德在经济学界最为大家所熟知的却是宏观经济学中以其名字命名的戴蒙德模型。

具有生产部门的OLG模型戴蒙德模型是为宏观经济模型建立微观基础的两大基本模型之一(另一个是拉姆齐模型),也被称为代际交叠模型(Overlapping Generation Model,以下简称“OLG模型”)。

从经济学史的角度来看,该模型最初是由法国经济学家莫里斯·阿莱斯在1947年的一本教科书中提出的,然而阿莱斯的工作在经济学界几乎没有任何影响。

1958年,著名经济学家保罗·萨缪尔森在讨论利率的决定问题时提出了一个纯交换经济的OLG模型,并用来讨论货币在经济中的作用。

1965年,戴蒙德又建立了一个具有生产部门的OLG模型,并用来讨论资本积累的黄金律以及国债在经济中的作用。

正是由于戴蒙德的OLG模型引进了生产部门,所以该模型得以成为现在教科书中的标准模型,有的教科书甚至直接称之为戴蒙德模型。

戴蒙德模型讲述的是这样一个故事。

在一个只有一种产品的经济中,假设该产品由劳动要素和资本要素共同生产,该产品既可以用于消费,也可以作为投资品用于投资。

再假设个人的生命分为两期:年轻时期和老年时期。

年轻人具有生产能力,但老年人没有生产能力。

由此,整个社会在任何一个时期都只包括两种类型的人:具有生产能力的年轻人和没有生产能力的老年人。

H-O理论的扩展1. 斯托珀——萨缪尔森定理2. 要素价格均等化定理3. 罗伯津斯基定理4. 特定要素模型1.斯托珀——萨缪尔森定理(S-S定理)☐某一商品相对价格的上升,将导致该商品密集使用的生产要素的实际价格或报酬提高,而另一种生产要素的实际价格或报酬则下降。

☐推论:国际贸易会提高该国丰裕要素所有者的实际收入,降低稀缺要素所有者的实际收入。

均衡状态下,劳动和资本的价格分别为:w=MPLxPx =MPLyPyr=MPkx Px =MPkyPyw/px=MPLx w/py=MPLyr/px=MPkx r/py=Mpky因此劳动的实际收入下降,资本的实际收入增加。

2. 要素价格均等化定理(简称H-O-S定理):对于同一种要素,自由贸易会使它在供应丰裕的国家价格上涨,在供应稀缺的国家价格下降,在生产要素不能在国家间自由流动的假设前提下,产品的自由贸易会使两国同一生产要素的价格逐渐趋于均等化3. 罗伯津斯基定理在商品相对价格不变的前提下,某一要素的增加会导致密集使用该要素部门的生产增加,而另一部门的生产则下降➢如果是本国相对丰裕的要素的增加,将导致本国出口部门的生产扩大,进口竞争部门的生产缩小。

在需求不发生变化的情况下,贸易量扩大,本国的贸易条件恶化。

如果是本国相对稀缺的要素增加,则相反。

➢如果本国是一个小国,即使不影响国际价格水平的话,贸易量发生变化,但是贸易条件不变。

➢如果是本国相对稀缺的要素出现增长,则有可能会出现要素丰裕度的逆转,即比较优势逆转例:开发新的资源型出口产品可能会带来被通称为“荷兰病”(Dutch Disease)的问题。

这是根据荷兰在北海开发新的天然气资源后所遇到的不利情况而命名的。

荷兰越是增加天然气的生产,其生产出口产品的制造业就越是萧条,甚至在两次石油危机冲击时期由于油价上涨给荷兰带来意外收入,同时也加剧了工业的衰落。

大量资源型产品的出口带来巨额外汇收入,导致本币升值,进一步削弱本国工业品的出口竞争力。

Economics50:Intermediate MicroeconomicsSummer2010Stanford UniversityMichael BaileyLecture1:Supply,Demand,and Elasticities1OverviewA market is a collection of agents who want to trade.Market demand and supply is the summation ofthe individual demand and supply.A very useful metric is how much quantity changes with respect to price.The slope of the demandcurve is one way to measure this,but the slope depends on the units of measurement.The own price elasticity,the percentage change in quantity demanded per percentage change in price, is a unit-less measure of the response and is denoted by"Q;P=% Q% P:"Q;P< 1)own-price elastic"Q;P= 1)own-price unit elastic0<"Q;P< 1)own-price inelastic"Q;P>0)Gi¤en Good(upward sloping demand)Every linear demand curve has an own-price inelastic and elastic region.Elasticity can change depending on the starting point before the price change.The Arc Elasticity is used more often in practice because it gives the same value no matter which points are used as thestarting or ending points:ARC"Q;P=Q1 Q0Q1+Q0P1 P0P1+P0for starting points(P0;Q0)and ending points(P1;Q1):The own-price elasticity of a good is determined by the availability of substitutes and complements, the portion of one’s budget the good occupies,and time horizon considered(short run vs.long run).If we make an assumption about the shape of the demand curve,we can identify the parameters of the demand function if we know the elasticity at a given point on the curve.Change in expenditure for a good per change in price is a function of the own-price elasticity of the good.1These lecture notes draw heavily from the notes of Luke Stein and Manuj Garg,the previous instructors of Econ50during the summer(and presumably they based their notes heavily on previous instructors,so on and so forth),as well as the class notes of Ran Abrimitzky and Mark Tendall,the academic year professors of Econ50.The income elasticity of demand is the percentage change in quantity demanded per percentage change in income"Q;I=% Q% I:The cross-price elasticity of demand is the percentage change in quantitydemanded per percentage change in another good’s price"Q;Py =% Q% P y:"Q;I>0)Normal Good "Q;I<0)Inferior Good "Q;I>1)Luxury Good "Q;Py>0)"Q;Py <0)Good X and Y are SubstitutesGood X and Y are ComplementsMarketsA market is a collection of agents who want to trade.Note that the de…nition of someone who"wants"to trade could be interpreted in a very general way.An agent might only be willing to trade for the item at prices that are never seen in the market,and thus never engages in trade in the market,and yet still might be considered as part of the market.In practice,it is usually those who are actively trading in the market that are considered part of the market and those who could potentially be a part of the market if the prices are low,or high,enough are considered part of a potential market.The reservation price is the maximum price the buyer is willing to pay to acquire the good,and the minimum price the seller is willing to accept to sell the good.The individual demand is a function that expresses the quantity of the good demanded by the individual at each price.The market demand is a function that expresses the quantity of the good demanded by all the individuals in the market at each price.Example1Market for IpodsWe organize the market by dividing up the agents into"buyers"and"sellers".For simplicity we will say that the buyers each want one,and only one,Ipod and the sellers each own one,and only one,Ipod.We sort the buyers by those with the highest reservation price to those with the lowest,and the same with the sellers. Figure1shows the amount of Ipods demanded by John,the buyer with the highest reservation price,at each price.Notice that John demands1Ipod when the price is below100$and0otherwise.Figure2shows the amount of Ipods demanded by Mary at each price.Figure1:John’s Demand for an IpodFigure2:Mary’s Demand for an IpodThese are individual demand functions.If John and Mary were the only buyers in the market,the amount of Ipods demanded by the buyers for each price would be represented by Figure3.Figure3is the market demand function if John and Mary are the only buyers in the market.Figure3:Market Demand for John and MaryWe can do the same thing for the sellers and construct individual supply functions and the market supply function.Incorporating a few more buyers and sellers and the market demand and supply functions begin to look linear,see Figure4.Notice the market curves jump when a buyer or seller enters the market.If there are many buyers and sellers,as a market at the national level would have,the discrete bumps in the graph would be smoothed out and we would get the typical"Demand and Supply"graph in Figure5.Figure4:Market Demand and Supply with Some Market ParticipantsFigure5:Market Demand and Supply with Many Market ParticipantsIndividual demand could be a function of many things including tastes,weather,time of the day,etc.In this class,we only consider a simpli…ed demand that is a function of market prices(P x;P y;:::P z),and the individuals income.X i(P x;P y;:::P z;I i)=Individual demand for good X of agent iP x=Price of good xI i=Income of Individual iExample2Linear DemandX i(P x;P y;:::P z;I i)=a b x P x b y P y::: b z P z+I iThe market demand is the summation of the individual quantity demand functions of the individuals in the market and is assumed to be a function of market prices and the incomes of the agents in the market. For goods X and Y we would denote market demand by Q x and Q y and individual demand by X i and Y i respectively.Q x(P x;P y;:::P z;I i;I j;:::;I n)=Market demand for good X=nX i=1X i(P x;P y;:::P z;I i)Example3Linear Demand:Suppose there are10agents in the market with linear demand X i(P x;P y;:::P z;I i)= a b x P x b y P y::: b z P z+I i;what is the market demand curve?Q x(P x;P y;:::P z;I i;I j;:::;I n)=10X i=1X i(P x;P y;:::P z;I i)=10X i=1a b x P x b y P y::: b z P z+I i=10(a b x P x b y P y::: b z P z)+10 X i=1I iFor each demand curve,there is an associated inverse demand curve,which relates the price required to generate the quantity demanded.To get the inverse demand from the demand function,just solve for the price as a function of quantity demanded.P x(Q i;P y;:::P z;I i)=Inverse demand for good X of agent iExample 4Linear DemandX i (P x ;P y ;:::P z ;I i )=X i =a bP x +I i bP x=a +I i X i P x =a b +1b I i 1b X i =Inverse DemandWe typically use,and plot,the inverse demand curve.It is useful to remember that if price is on the y-axis,the graph is of inverse demand (price as a function of quantity).If quantity is on the y axis,we are working with the demand function.Figure 6:Demand Function Q =a bPFigure7:Inverse Demand P=ab 1b QThe Law of Demand is that demand functions will be downward sloping.This requires that quantity demanded decreases as price rises.A good where quantity demanded rises with the price is called a Gi¤en Good and examples are rare.In theory,it could be that the income e¤ect outweighs the substitution e¤ect (more of this in later lectures)and so a price increase of an inferior good would cause demand to rise.For example,suppose that you need to eat2potatoes to live.You would de…nitely like to have some meat with your potatoes,but meat is expensive.Suppose your income is$10,potatoes are$2each,and a serving of meat is$6.You would then consume2potatoes and one serving of meat.If the price of potatoes rises to $3,you would then consume3potatoes as you can no longer a¤ord meat.In this example,potatoes are a Gi¤en Good.Notice that in our model of individual demand,X i and P x are explained by the model and a;b;and I i are not explained by the model but given in the problem.Variables that are explained by the model are endogenous,and variables not explained or"outside"the model are exogenous.EquilibriumA market is in equilibrium when quantity demanded equals quantity supplied.Recall from Economics1A that price and quantity changes are movements along the demand(supply)curve and are called changes in quantity demanded(quantity supplied),but if the relationship between quantity demanded(or supplied) changes for all prices,this is a shift in the demand(supply)curve and is called a change in demand(supply). Demand shifters include changes in tastes,income,market characteristics,among many others.Supplyshifters include changes in costs,working conditions,government regulations,among many others.Notice that the shape of the demand and supply curves plays a big part in where the equilibrium is,and more importantly how quantity changes in response to price changes.In Figure8,an increase in demand leads to both a price and quantity increase,whereas in Figure9,it only leads to a price increase.ToFigure8:An increase in income has shifted demand from Demand0to Demand1,leading to a new equilib-rium E1:Both price and quantity demanded increase.understand market behavior,we must know how changes in price will a¤ect changes in quantity.One way( = to measure this is by taking the change in quantity demanded divided by the change in price, QP change, Q=(Q1 Q0)where Q0is the initial quantity demanded and Q1is the new quantity demanded). This is equal to the slope of the demand curve(Figure6),or the inverse of the slope of the inverse demand curve(Figure7).One problem with this measure is that it is sensitive to the units used.Quantity demanded has quantity units like gallons,or Ipods.Price has units of dollars or Euros.Thus Qwould have units like gallons perPEuro,or Ipods per cent.Figure 9:An increase in income has shifted demand from Demand 0to Demand 1,leading to a new equilib-rium E 1:Because Supply is …xed,only price increases.ElasticityThe own-price elasticity of demand is the percentage change in quantity divided by the percentage change in price and is denoted by "Q;P =% Q% P (or "X;P x if referring to individual demand for good X ):This is aunit-less measure of the responsiveness of quantity demanded to price.% Q =Q 1 Q 0Q 0gallons gallons P 1 P 0P 0dollars dollars =Q 1 Q 0Q 0P 1 P 0P 0Remark 5For a downward sloping demand curve,the elasticity will be negative.It is convention in eco-nomics to report the absolute value of the elasticity.In this class,we will not use this convention.Example 6Linear Demand:If the inverse demand function is given by P x =40 Q ,what is the own-price elasticity of demand as the price changes from $20to 19$?From $34to $35?"Q;P =Q 1 Q 0Q 0P 1 P 0P 0=21 202019 2020=120 120= 1"Q;P =Q 1 Q 0Q 0P 1 P 0P 0=5 6635 3434= 16134= 173Figure 10:Example 6If we want to compute elasticity at a point,we need to consider an in…nitesimal changes in the price at that point:"Q;P=lim P !0% Q% P =lim P !0QQ P P=limP !0 Q P P Q =@Q @P PQExample 7Linear Demand:Find the own-price elasticity as a function of the price for the demand function X i =a bP x at any point.@X i= b P x X i =P x a bP x"X;P x= bP xa bP x Notice that"X;P x (P x =0)=0lim P x !a b"X;P x (P x )= 1"X;P x (P x =a 2b )= 1Since this was derived from a general linear curve,this is true for downward sloping demand curves,the midpoint has elasticity 1,and the elasticity converges to 0and 1at the endpoints,see Figure 11.Theterminology we use is that if the elasticity is:"Q;P< 1)own-price elastic"Q;P= 1)own-price unit elastic0<"Q;P< 1)own-price inelastic"Q;P>0)Gi¤en Good(upward sloping demand)Figure11:All Linear Demand Curves have an Own-Price Elastic,Unit Elastic,and Inelastic Region.Thus every linear demand curve has an inelastic region,and an elastic region,separated by the midpoint. (note that if"Q;P>0;the demand is upward sloping).It is critical to understand the intuition behind this result.Why would a linear curve with an unchanging slope yield such di¤erent estimates for a percentage change in quantity demanded per percentage change in price depending on the starting point?When quantity is very small,a small increase could be a very large percentage increase.Consider the inverse demand curve P x=40 Q:If Q=0:001;P=39:999and a change in the price of$1would be small in percentage terms(1=40=2:5%);but it would lead to a huge percentage change in quantity(1=:001=1000%):That is why the elasticity is converging to-1:Similarly if we considered the point P=0:001;Q=39:999;we would see huge percentage changes in the price for price changes and very small percentage changes in quantity,thus leading to an elasticity near0.Remark8If every linear demand has an elastic and inelastic region,why do we call some linear demand curves elastic and others inelastic?This is an abuse of terminology,there is no way you can say that a linear demand curve is elastic or inelastic because every linear demand curve has an elastic and inelastic portionseparated by the midpoint.What is usually meant is that over the regions of the lines being compared,one is relatively more own-price elastic than the other.Example 9Constant Elasticity Demand Function:Let demand be given by X i =aP bx ,what is the own-price elasticity as a function of the price?@X i= abP b 1xP x X =P x aP x=P b +1xa "X;P x= abP (b +1)x P 1 bxa= bThe elasticity is a constant, b;and so the percentage change in quantity demanded X i is proportional to the percentage change in the price at all prices.Remark 10Remember that the formula for elasticity with the derivative is for in…nitesimal changes in the price.If you take discrete changes in the price,you will get a di¤erent elasticity estimate.For example,for the constant elasticity function with a =1;b =1,consider a price change from 1to12;quantity demandedincreases from 1to 2,and "X;P x = 2;which is not equal to 1from the above calculation.However,as you let the price change get smaller and smaller,the elasticity will converge to 1:Remark 11X i =aP bx is the only constant elasticity demand function.Figure 12:X =aP b for a =1and b = 2;1;201234512345QuantityPriceFigure 13:X =aP b for a = 2;1;2and b =112345-5-4-3-2-1012345QuantityPriceArc ElasticitySuppose we computed the elasticity for a price increase from $1to $2.Would this be equal to the elasticity for a price decrease from $2to $1?Earlier,we found in the case of P x =40 Q that for a price increase from $34to $35the own-price elasticity is 173.The own-price elasticity for a price decrease from $35to $34is:"Q;P =Q 1 Q 0Q 0P 1 P 0P 0=6 5534 3535=15 135=355= 7= 173The problem is that the base price and base quantity is changing.In practice,economists use a measure of the elasticity that does not depend upon the starting point used,this is called the Arc Elasticity and is equal to:ARC"Q;P =QAV ERAGE (Q )PAV ERAGE (P )=Q 1 Q 0(Q 1+Q 0)=2P 1 P 0(P 1+P 0)=2=Q 1 Q 0Q 1+Q 0P 1 P 0P 1+P 0Example 12Constant Elasticity Demand

little rearranging:d log(Q)=dQ Qd log(P)=dP Pd log(Q) d log(P)=dQQdPP="Q;PRemark13The change in the logs is equivalent to percentage changes.If you plot the demand curve on log-log paper,the slope at any point is equal to the own-price elasticity.Example14Constant Elasticity Demand Function:X i=aP b xlog(X i)=log(aP b x)=log(a)+log(P b x)=log(a) b log(P x)d log(X i)x = b="X;PxIn practice,elasticities are commonly measured by estimating the function log(X i)=log(a) b log(P x) using linear regression techniques(regressing log(X i)on log(P x)):The coe¢cient on log(P x)is the elasticity.One problem with estimating the elasticity using real world data is that observations are just a cloud of(Price,Quantity)combinations.All we know is that this is where quantity supplied equals quantity demanded.We don’t know whether these points are from shifting demand or supply.This is known as the identi…cation problem.To get identi…cation,you need to…nd a time in the market where you can argue that demand shifted or supply shifted while the other did not(natural experiments).Much easier in a market with a constant supply(housing)or a market like electricity where there is a monopolist who can supply the whole market at any price and you can observe how demand changes as price is varied.Identifying Demand Curve Using ElasticityIf we make an assumption about the shape of the demand curve,we can estimate the parameters from an elasticity estimate.Example15Suppose we know that at P x=20;Q=20;"Q;P= 1:We further assume that demand is linear:Q=a bP x:What can we say about a;b?"X;Px =@Q@PPQ= bPQ= 1b= Q P= 1b=120=a 20a=40What Determines the ElasticityIs there a way we could tell what products would be own-price elastic or own price inelastic?How should we think about elasticity intuitively?Substitutes/Complements:Demand for a good is more own-price elastic when there are good substi-tutes for the good.If there are good substitutes,even a small increase in price might lead many people to buy the substitute.Example:Butter and"I Can’t Believe It’s Not Butter!".Demand for a good is more own-price inelastic when there are complements to the good.Example:Iphone apps.High Need/Addiction:Demand is less own-price elastic when the good is addictive or when there is critical need for the good.Examples:Cocaine and Vaccines.Portion of Budget:Demand is less own-price elastic when a consumers expenditure on the good is small relative to income.Example:Cereal.Time Horizon:Demand is less own-price elastic in the short run compared to the long run.Example: Gasoline.Others:You might think of other good characteristics that a¤ect elasticity.For example,there are some goods,like software programs,that take a large investment to learn.It is costly to switch to a substitute so the good will be less own-price elastic.Example16Cigarettes"Q;P= 0:107 Breakfast Cereal"Q;P= 0:031 Cigars"Q;P= 0:756 Vacation Airline Travel"Q;P= 1:52 Bus Travel to Work"Q;P= 0:04 Oil,U.S."Q;P= 0:061Price Elasticity and ExpenditureThere is a link between own-price elasticity of demand and expenditure on goods.Suppose we wanted to see the sensitivity of expenditure to changing prices.Expenditure on good X by agent i equals P x X i=E which also equals seller revenue.Recall that X i(P x)is a function of the price.@E @P x =P x@X i(P x)@P x+X i(P x)=X i(P x)P xX(P

「知觉的」想像抑或「想像的」知觉——从胡塞尔现象学中知觉与想像二者间之优位问题来看知识如何建立

「知觉的」想像抑或「想像的」知觉——从胡塞尔现象学中知觉与想像二者间之优位问题来看知识如何建立

知覺的」想像?抑或「想像的」知覺?——從胡塞爾現象學中知覺與想像二者間之優位問題來看知識如何建立政治大學哲學研究所碩士班江偉峰前言:胡塞爾現象學,作為這百年來推動歐陸哲學向前進展之一種主要思想運動的道路,其引人注目的最鮮明特徵,即是為一切認識活動尋求絕對確定的可能性根基,以便完成「回到事物本身」進行真理認識之嚴格徹底的要求,而其所採行的方法,則是一方面藉由對理所當然的素樸認識(在素樸態度下)實行「懸擱還原」,使隱匿其中之純粹內在的意識功能主體得以顯露(在超驗態度下),另一方面,則以「直觀」的源初給予,作為一切認識活動的最高原則及一切認識內容最終合法性的來源。

本文嘗試通過對胡塞爾現象學思路的追溯,探討在現象學式的認識活動裡,「知覺」與「想像」此二意識如何發揮著重要的核心功能。

因而主要的目標任務,無非就是廓清「知覺」與「想像」各自固有的本質特性和此二者間的相互關係,以便闡明「沒有知覺,就沒有想像;沒有想像,則知識畢竟無法建立」的根本要旨。

故本文所涉內容將依序展開如下:一、「知覺」的認識活動——從「超越物的經驗直觀」與「超越物的本質直觀」之相互奠基關係談起;二、「知覺意識」與「想像意識」的基本區分——從「變樣」此一意識基本特性方面加以考察;三、知覺意識與想像意識之「被動性發生」的深層機制——就內在性時間意識領域中的「聯想作用」來闡明;四、結語——「知覺的」想像與「想像的」知覺。

一、「知覺」的認識活動——從「超越物的經驗直觀」與「超越物的本質直觀」之相互奠基關係談起胡塞爾,這百年來不斷啟迪現象學哲學運動發展之最初創始者,在其晚年最後力作《歐洲科學危機與超驗現象學》一書中,明確地通過一種現象學式之對西方近代以來科學與哲學歷史的沈思回溯探究,指明了西方近代以來整個科學與哲學的發展是如何受制於客觀主義心物二元論前提的影響支配,以致或多或少都抽象扭曲了心靈與物之固有本質的存在意義。

這種抽象扭曲的直接結果,不僅止造成人類對於自身、對於生活世界之意義片面膚淺化的空洞,在人類追求知識真理,更由於無法徹底理解自身方法基礎中深藏之不可理解的謎,即「世界客觀性如何能被主觀地認識」此一非比尋常的謎1,而讓西方近代以來的科學與哲學,都失去了知識的真正嚴格性,因而根本說來,都不配作為任何一門真正的科學與哲學。

霍夫斯泰德文化维度理论在全球会展代理业务中的应用

36中国会展 CHINA CONFERENCE & EXHIBITION调查·SURVEY霍夫斯泰德文化维度理论在全球会展代理业务中的应用案例分析与研究● 文:肖云飞 ● 责任编辑:常予莹****************随着全球化的不断发展,国际商务和全球会展业务在促进全球经济发展中发挥越来越重要的作用。

全球会展代理业务在开展过程中常受到不同国家和地区之间的文化差异影响。

这些文化差异包括商务礼仪、语言、价值观、沟通方式和决策风格等,都可能对商务合作产生重大影响。

因此,在全球会展代理业务中,了解并应用文化维度理论变得至关重要。

霍夫斯泰德的文化维度理论提供了一个有力的框架,用于分析和理解不同文化之间的差异。

该理论包括多个文化维度,如个人主义与集体主义、不确定性回避、权力距离等,它们可以帮助人们解释文化之间的差异,预测跨文化交流的障碍,并指导跨文化管理的策略制定。

本研究以作者亲历的跨文化事件为案例。

通过分析案例,本研究将探讨如何通过应用霍夫斯泰德的文化维度理论更好地开展国际会展代理业务,进而为国际会展代理业务的从业者提供有益的见解和建议。

Application of Hofstede's cultural dimensions theory in global exhibition agency businessCase study and research2023年12月15日第23期 总第551期37一、霍夫斯泰德文化维度理论PeterG.Northouse (2012)在他的著作《领导学:理论与实践》中强调了文化的重要性。

他指出,文化是一群人所共有的传统,这一传统包括了习得的信念、价值观、规则、规范以及符号。

文化是人们的思维方式和行为的背后力量,它塑造了人们对世界的看法和人们如何与他人互动。

在众多文化理论中,霍夫斯泰德的文化维度理论脱颖而出,成为了全球跨文化研究领域的经典之一。

哲纳理论第一期高级第三节(2011-10-18)

哲纳理论内部资料不得外泄一经发现立即清出东方哲纳期股培训学校第一期高级课程第三节(蓝色:雪飞老师黑色:宝图老师粉色:学员)那先来个思考题,《黄金为何听话》既然人反正经常不是满数,那么课的时间也不用那么死我讲的话,也不一定按时间,届时看课件也行这样大家之间时间上,灵活些我感觉老师做单是看美元,做他的反方向,美元日线级是不是按四杰上图模式走的?我认为黄金哲纳上涨时间和空间都到位了,剩下时间和空间是向下的不用再单独说窗口一多,我的脑子就嗡嗡的一天,这个脑子一个劲的不闲着,脑子是练活了,但是寿命是不是受影响呢据说脑子越用越活你们也要用用你们说的都不够细雨同志是抓小放大但是动脑子了其他同志连脑子都没动,顺嘴就嘞嘞至简思维:顶部下降15天然后反弹**天?反弹空间?三分之一30%所以我吃货?所以当时单子贴出来了为何不等0.5?如何在洛书图中,整出先天八卦顺序来。

怎么又扯到洛书上去了整出来,也没用,都不明白,就你明白半年了,这个问题时时刻刻困扰着我。

我一下子说不出语言来你们问话,我都是现想用词好累原理,一般我不是按逻辑推出来的我大多数,就是突然一想,就知道了,真不知理由,理由都是后找的比如超级大四浪,就是斜归零时空不能按讲课说的那样其时空一揽子计算,要用平方开方导数联合公式计算我就是突然一想,这个公式就有了复合公式压根没有推导过程就直接出来一个结果性公式一实践,点数,时间数,一点不差一直以为,我想到的,别人也能想到,压根不以为然没什么但看到你们就是讲解,理解的也很吃力,才感觉自己还算不笨后来一照镜子,才知道,原来我是反向梳头建议你们也反梳头但是这个公式,是超级大转折时,才能用到是牛市和熊市的末梢的清醒公式牛叉公式,和熊叉公式无所谓一般用不上15 VS 15这就是斜归零周期以卦对卦为时间分布下15天一卦反弹15天,不也是一卦吗反弹15天没返回顶部,不就是下降通道吗失败的5浪?定义为艮就是了,下降的15天定义为坤C就是了我说的没有如果阴阳周期时空是对称的,终究是对称的假如处于百千年的上升通道中,千万不要认为没有对称其后的对称,就是走向灭亡人类自从释迦牟尼诞生之后就是下降通道中我们身处其中,而不知而已他的诞生,就是告诉我们,在熊市里怎么做人ABC或CBA牛市里不需股评熊市里需要有人安慰在上升通道的途中的中级熊市,与上升通道的关系,就是斜对称周期美国百年中著名的两次特大经济危机股灾,也不过是上升通道的中级熊市但是途中,相对的周期对称,有的是斜对称周期,说白了,飞哥定义为四浪与一二三浪的关系5522-1664,仍然叫做四浪假如不动脑子的人,一般都说,998-6124为牛市,6124-1664为熊市就是这个道理他们只看到了上去了,又下来了,没有深究而已神马经济危机不存在只是钱在大量减少而已是6124的钱在减少998的钱并没减少所谓经济危机,不过是998 的人抢6124的人的钱而已换一换口袋或者叫做财力通过上交所进行转移6124时,你大吃二喝,只不过是吃自己的998-6124与6124-1664,就是斜对称周期325-2245与2245-998,亦然定义:斜对称周期,就是在历史中,无限的走1234、一二三四、(一)(二)(三)(四)不走5678只走阳鱼,不走阴鱼4就是阴鱼所以,998点之后,其主升浪结束于1664易纬你用波浪理论根本划不了历史的通浪能画历史通浪的,只有一人飞哥飞哥老飞从不看别人怎么划浪就是有时有点纠结,也不看他们的有时浏览一下,看看题目拉倒我也不看别人,只学飞哥技术反正谁也不信万般皆下品唯有象浪高比如,你们服巴菲特吗04、05、06,连续亏损40%人,只看重绝对值我们要看其比例记得那个深圳老太太,买深锦兴的吗啥也不懂,买了睡了几年大觉,醒来翻了好几十番那么报纸若把她请出来,告诉你怎么投资。

哲学思想论述

哲学思想论述

哲学思想论述哲学,作为人类智慧的结晶,自古以来便在探索宇宙、人生与思维的本质。

它不仅是一种思考方式,更是一种生活的艺术,引导人们深入理解世界与自我。

本文将围绕几个核心的哲学思想进行探讨,旨在为读者提供一个关于哲学思想的概览。

存在主义存在主义强调个体的自由、选择和个人责任。

让-保尔·萨特(Jean-Paul Sartre)认为“存在先于本质”,意味着人首先“存在”,然后通过自己的行动创造自己的本质或身份。

这种思想鼓励人们勇敢面对生活的荒诞性,通过自主的选择来赋予生命意义。

实用主义实用主义由查尔斯·桑德斯·皮尔士(Charles Sanders Peirce)、威廉·詹姆斯(William James)等人提出,主张以实际效果和用途作为真理和价值的标准。

实用主义者相信,一个观念的真实性在于它是否能够有效地解决实际问题,促进个人和社会的发展。

分析哲学分析哲学强调逻辑分析和语言的清晰性。

它起源于20世纪初的英美哲学界,代表人物如贝特兰·罗素(Bertrand Russell)和路德维希·维特根斯坦(Ludwig Wittgenstein)。

分析哲学家试图通过逻辑和语言的分析来澄清哲学问题,避免传统哲学中的模糊和混乱。

现象学现象学由埃德蒙德·胡塞尔(Edmund Husserl)创立,主张直接面向事物本身,排除一切先入为主的偏见和理论假设。

现象学强调意识的主体性和意向性,试图揭示事物如何在意识中呈现,以及意识如何构成我们对世界的理解。

结构主义结构主义认为,人类文化的各种表现形式,如语言、神话、社会习俗等,都是由潜在的结构决定的。

克劳德·列维-斯特劳斯(Claude Lévi-Strauss)将其应用于人类学研究,强调通过揭示这些结构来理解人类社会和文化现象。

结论哲学思想的多样性反映了人类对世界的不同理解和解释方式。

从存在主义的自我实现到实用主义的效用原则,再到分析哲学的逻辑清晰和现象学的直观体验,每一种哲学都提供了独特的视角和思考工具。

Hofstede’s graph tells us something
• What is the meaning of the following graph?
Scale of Hofstede’s cultural dimensions
Let’s look at examples of each of the 5 dimensions
• Women play small role in society • Household work and shopping as an indicator of masculine/feminine culture
Masculine vs. femininism
Masculine: U.S. values competition and success in business
4. Uncertainty avoidance (cont’d.)
• High uncertainty avoidance
– – – – Need for rules and formality to structure life Search for truth and belief in experts Less open to change and innovation Passive attitude toward health
– everyone has his or her rightful place in social hierarchy – Social status must be clear so that others can show proper respect
• Low power distance cultures:
• • • •
Start with culture
• Culture is the core concept in intercultural communication • What is culture?
– Learned patterns of perceptions, values and behaviors shared by a group of people
• Defined as “the extent to which less powerful members of a society accept and expect that power is distributed unequally” • High power distance cultures:
• Focus on sports and fitness
High vs. low uncertainty avoidance
Low uncertainty: willingness to take risks; accept dissent High uncertainty: prefer rules and regulations
– How do we compare patterns of communication? – How do we compare meaning?
Hofstede’s Dimensions of cultural values
• Dutch social psychologist
• Identified cultural values that help us understand cultural differences
Foundation of intercultural communication
Building blocks of intercultural communication Building block #1 = culture Building block #2 = communication Building block #3 = context Building block #4 = power
