1. 吉他Dm7和弦的小横按有什么诀窍
不管你是对爵士乐即兴有兴趣的学习者,或是听音乐找资料的乐迷,相信一定会常常听到爵士乐手或是评论资料上说到「2-5」,这到底是什麼?为什麼大家都在谈?是的,这是在爵士乐中很重要的和声概念,所以我们先把它放到爵士曲式中来谈。
所谓的「2-5」或「Two-Five」,原出於一种和声进行上的动作,也就是低音的移动距离,会往下五度走,譬如如果是D和弦,那麼下个和弦就是G和弦,再下一个就是C和弦,这在许多被用来当作是爵士经典(标准)曲目的百老汇歌舞剧歌曲中,几乎是家常便饭,请参考本栏「使用同一和弦进行曲式的不同主题旋律」一文,观察许多曲子和弦根音(Root)的移动,便可一目了然。
这样的一个动作,便决定了许多事情,而这动作,在小调(Minor Key)中特别多,打从巴洛克时代的音乐就是如此,许多法国香颂也是如此进行,甚至在受巴洛克风影响的重金属摇滚乐中,也有数不清的例子。流行乐中,最有名的例子,莫过於Gary Moore的《Still Got The Blues》、Lionel Richie的《Hello》及兼具两首歌影子的黄品源《你怎麼舍得我难过?》︰
《Still Got The Blues》开头
Dm7 - G7 - CMaj7 - FMaj7 - Bm7b5 - Em7 - Am7
《Hello》副歌
Dm7 - G7 - CMaj7 - FMaj7 - BbMaj7 - E7 - Am7 - A7
《你怎麼舍得我难过?》副歌
Dm7 - G7 - CMaj7 - FMaj 7- Bm7b5 - E7 - Am7 - A7
请注意它们根音的走向,是不是都是往下五度?这五度不只有完全五度(Perfect 5th),还包括了调性内的五度—大多是减五度(Diminished 5th),简而言之,这样的和声模式,就是在一个小调中将调性和弦(Diatonic Chords)以五度下行的方式排列罢了!以上三首曲子,都属於A小调。在爵士乐中,各位还必须知道三首最有名的曲子,那就是原来也是法国香颂的《Autumn Leaves》、Jerome Kern的《All The Things You Are》,以及Bart Howard的《Fly Me To The Moon》,请大家自行去分析一下,证明这个“惯性”的存在。
这也是为什麼,在大多数的爵士乐教学体系中,总要我们练习「五度循环」(Cycle of Fifth)的缘故,因为这样练习能帮你克服转调的问题︰
CMaj7 - FMaj7 - BbMaj7 - EbMaj7 - AbMaj7 - DbMaj7 - GbMaj7(F#Maj7) - BMaj7 - EMaj7 - AMaj7 - DMaj7 - GMaj7 - CMaj7
Cm7 - Fm7 - Bbm7 - Ebm7 - Abm7 - Dbm7 - Gbm7(F#m7) - Bm7 - Em7 - Am7 - Dm7 - Gm7 - Cm7
C7 - F7 - Bb7 - Eb7 - Ab7 - D7 - G(F#7) - B7 - E7 - A7 - D7 - G7 - C7
尤其是第三个属七和弦的循环,我们在谈到「Rhythm Changes」时已介绍过。而转调练习的重要性,我们也已提过了,相信你一定能体会把句子、段落或曲子拿来转调练习的好处了!
那麼如果我们先回到一个大调之中,先看看它们的顺阶和弦—亦即调性内和弦—如何?
四个音的顺阶七和弦把它们分开来演奏,就是在爵士语汇里提过的「琶音」(Arpeggio)啦!根据我们上面谈到「往下五度走」的原则,最重要的就是「属到主」的进行,也就是五级到一级,从巴洛克时代确定大小调(Tonality)之後,这动作可说是影响了几百年来音乐的发展,包括你在小学时音乐课教唱的歌,或是去KTV欢唱的流行金曲,最後都会有这个「V-I」的和弦进行,在术语上我们叫它「解决」(Resolution),长一点的我们称它为一个「终止式」(Cadence),像音乐老师常常弹的和弦就是︰
C - F - G7 - C
C - F - C/G - G7 - C
用功能和声(Functional Harmony)的角度来看,这样的进行都符合「主—下属—属—主」的进行,也就是「T-SD-D-T」(Tonic-SubDominant-Dominant-Tonic),我们今天不打算钻研古典和声理论,请各位自己去找书或问音乐系的同学,我们要探讨的,是到了爵士乐里,大家会怎麼做?
很简单!先找出这个调的属七和弦,再解决到主和弦,以C大调来说,就是G7-Cmaj7,接下来,再援引五度下行的原则,回头去找调性内哪个和弦应该摆在G7之前?Yes!就是Dm7和弦,这样我们就找到了「Dm7-G7-CMaj7」,也就是调性里标准的II-V-I。(注︰别忘了五度下行就等於四度上行,我们在音程里有提过)请注意这个Dm7,跟正宗的下属和弦才差一个音而已,因此它也是属於下属类的和弦,也就是变成「SD-D-T」,不一定要从一级主和弦开始。所以,在爵士乐里,这样的动作变得非常重要,聆听数百首标准曲目,都涵盖了这样的和声进行,几乎只要看到IIm7-V7-IMaj7,我们就快就可以确定调性,这也称作「张力—解决」(Tension-Release),相信只要在钢琴或吉他上一弹,各位就可以感受到。您还必须练习转位(Inversions),把每一组和弦的转位都找出来,这里还是只有C大调的而已,重点是要熟悉它们的声响︰
>>
可是,这样我们就满足了吗?当然不!爵士乐是一种即兴的艺术,而这种艺术来自於音乐家如何即时创作与互动反应,所以它具备的特性,就是「四两拨千斤」的效果,等於是看准走势、最小投资、最大利润(这是在教人家玩股票吗?…),而在此处它的秘密到底在哪里呢?就在两个重要的关节,中文我们译之为「导引音」(Guide Tones),也就是每个和弦的3音与7音︰
IIm7-V7-IMaj7的导引音,正如连环扣一般,让每一步动作都有了依据,而且用最少的移动,就可以获得最大的效果,共享的音(Common Tones)不动,动一子而定全身,和声进行的色彩就这麼地勾勒出来,请赶快试试看!现在,你就可以藉由这种导引音顺畅进行的原理,把转位重新整理一遍罗︰
>>
帅呀!这样弹奏才会有好的和弦进行效果(Voice Leading),爵士的基本声响才会出来,先不要管什麼9音、11音、13音等等,这些能练好最重要,这年头我实在看到太多光说不练的人了!这个部份先巩固好,才有谈下去的可能,各位也会藉由对和声色彩的了解,而对旋律即兴更加地掌握,别忘了,连小号大师Dizzy Gillespie都要Miles Davis去练习钢琴哦!
接下来,就是转调练习的部份了,各位要很认真地把以上谈到的和弦配置(Voicing)十五个调都转来练,不能有一丝的犹豫,以下谨提供三种最实用的练法,如果你有任何的II-V-I小乐句(Lick),也必须要这样练,诀窍在於︰「从第一个和弦的哪个音开始,到第三个和弦的哪个音结束」的相对音程记法︰
一、照著五度循环走(四上五下)—
这是最基本的转调,也因此可以练到爵士乐最常见的降记号调,如此可将十二个调循环完毕,但如果您是指板弦乐器(Fretboard)如吉他、贝斯、提琴的话,建议再多想些指法,把十五个调练齐。记忆的诀窍在於把根音进行想成平行四边形◢◤。
bm7 (G#m7)Db7 (C#7)GbMaj7 (F#Maj7)Dbm7 (C#m7)Gb7 (F#7)CbMaj7 (BMaj7)F#↖
二、大二度下行—
所有的和弦配置与小乐句都会以大二度的距离平行往下移动,在爵士作曲中常会碰到这样的「Major7转Minor7」,亦即第一个调的CMaj7,进入下一个调时根音不动,和声色彩改为minor7,依此类推,请先练习,我们以後再慢慢归纳出来。请注意这样的跑法会有两个循环。
Dm7G7CMaj7↓7C#m7F#7BMaj7F#
三、小二度下行—
难度较高,所有的和弦配置与小乐句全部半音往下移动,强迫乐手克服盲点,这对指板弦乐器可能还好一点,只要往下移一格,但对管乐器跟键盤乐器来说是很辛苦的,因为都是不同的指法,不过练到这里能练好,II-V-I大概就很扎实了,请记得同样运用相对音程的方式记忆练习。
Dm7G7CMaj7C#m7F#aj7F#↖
依据「和声节奏」(Harmonic Rhythm)的概念,各位可以一小节IIm7、一小节V7、然後两小节IMaj7来弹奏并思考句子;和声节奏密集些,就是两拍的IIm7、两拍的V7,然後进到下一小节的四拍IMaj7,希望大家能花时间感受,这没有捷径,只能帮你减少胡乱摸索的时间。
那麼,如果只是单纯的IIm7-V7,可否单独存在?当然可以!而且还会更多,原来在百老汇经典曲的时代,这样的和声节奏大多出现在曲末时,以比较密集的感觉来迈向结尾,但从Bebop时期开始,一小节两个和声已经不足为奇,更不用提Hard Bop的作曲及即兴手法中,几乎就是“二五决定论”,看到什麼就想IIm7-V7,有二想五、有五加二,且待我们日後再慢慢深入。OK,那麼去掉了IMaj7,我们一样要练习以下三种「二五串」(II-V Chains)︰
四、五度循环—
请以属七和弦为主来往下走循环,这样IIm7就等於是相关二级七和弦(Relative IIm7),这会在谈到「延伸属和弦」(Extended Dominant Chords)时再拿出来强调,目前建议的快速记忆法为「Dominant7转Minor7」,对於和声色彩能尽快地掌握。
(C#m7)Gb7 (F#7)F#m7B7Bm7E7Em7A7Am7D7Abm7Db7↖
五、大二度下行—
跟第二项练法相同,只是去掉了Maj7,一样有两组。这会在谈到「装饰属和弦」(Secondary Dominant Chords)时再拿出来强调,各位可以先参考「Rhythm Changes的介绍与应用」一文,这也是很常听到的「III-VI-II-V」「Turnaround」和声进行之最佳练习法。
Dm7G7↓#m7F#7F#m7B7Bm7E7Em7A7Am7D7
六、小二度下行—
保证在运用「降二代五」(Substitute Dominant Chords)时得心应手,这项练习同样比较难,请参照「爵士乐中常用的调性及判断应用」一文中段,有很清楚的说明。
Dm7G7C#m7F##m7B7Fm7Bb7Em7A7Ebm7Ab7↖
与其坐在那清谈,不如赶快练习吧!这种有练就有得、没练啥都不晓得的硬底子功夫,将会成为我们爵士乐手往音乐深处探索的重要根基喔!
注︰除以上连结栈内文章之外,在爵士语汇各文中所提供的II-V-I例句,以及采谱分析中的曲子都有成堆的II-V-I,请用它们来转调练习!
2. 老百姓怎样炒股
老百姓炒股技巧如下:
要冷静持股 不要盲目售出
正确实施卖出操作,其学问并不在总想着如何高卖,频繁操作,而在于冷静持有,加强对与自己结缘股票的管理。不盲动、不躁动、不悸动,待时机出现时方从容售出。时常听到一些投资者埋怨,“手中的股票不卖它不涨,刚一卖就涨,甚至大涨”。其盲点在哪里,怎么才能把握住卖的时机呢?一是要看“季节”。如果我们仔细研究中国股市的变化规律,就不难看出其变化的周期性。而且这种周期性与自然界的变化很相似,其每个周期都是四季分明的。与此种周期性相适应,正确的操作策略应当是“春管、夏收、秋闲、冬储”,坚持在股价高企的股市夏天卖股票,在股市低迷的寒冬把手中的钱变成股票,这是股市盈利的正道。二要细分类。股市中的股票就其内在价值而言,客观上存在着好中差之分。首先按基本面把股票分为“好中差”三类,而后把每类股票按照“适中”、“向上背离”和“向下背离”分别做出估值状态分析,再根据它们背离的特点和背离值的大小做出其“即将修正”还是会“继续加深背离”的趋势判断。三观“风潮”。俗话说,无风不起浪。为什么股市中那么多垃圾股价格高高在上,而业绩和回报都较好的股票价格却很低?为什么同一支股票在很短的时间内股价相差几倍、十几倍?其实“山也还是那座山,梁也还是那道梁”,都是各种“风”吹出来的结果。
要有中途谋划 不要攻守失当
散户投资者在中局最容易犯的错误往往有三种,一是错把洗盘震荡当头部,惊慌失措掉下马。许多散户投资者受尽了底部长期套牢煎熬,好不容易盼到股价上涨,见了点儿盈利,一遇回调就心惊肉跳,仓皇出手。结果,股票刚一售出,股价就调头向上,不得已再去追高,形成连环错。折腾来折腾去,大盘指数涨了不少,而自己的账户资金却没有增加。二是盲目跟风追热点,一头撞入地雷阵。股市和实体经济是一种间接联系,股市的热点一般都是想象出来、制造出来的。三是错把后发当垃圾,扔掉黄金捡砖头。
散户在中局若要避免以上失误,把握投资主动权,需要很周密的计划性和较高的综合技战术水平。首先,要有股价上涨和下跌的两种心理准备,制订进退两套方案。其次,要锁定手中现有品种,分批分段,交替掩护,滚动操作。其三,要开阔视野,把握住轮动机会。由于受资金量的限制和吸筹控盘程度的影响,主力既不会把战线拉的太长,全面开花,也不会在吸筹不足的情况下盲目拉升,这就造成了不同板块、不同个股涨跌先后和程度的差异。但先涨不能总涨,后涨也不是不涨,市场的比价效应使不同板块的估值总是趋于平均。投资者依据个股纵向波动规律,实施波段滚动操作,把资金做多,是一种基本的获利模式。

给你 中文与英文两个版本 英文有没有翻译错的 对照你自己整理下
影响股票价格的因素
影响股票价格变动的因素很多,但基本上可分为以下三类:市场内部因素,基本面因素,政策因素。
(1)市场内部因素它主要是指市场的供给和需求,即资金面和筹码面的相对比例,如一定阶段的股市扩容节奏将成为该因素重要部分。
(2)基本面因素包括宏观经济因素和公司内部因素,宏观经济因素主要是能影响市场中股票价格的因素,包括经济增长,经济景气循环,利率,财政收支,货币供应量,物价,国际收支等,公司内部因素主要指公司的财务状况。
(3)政策因素是指足以影响股票价格变动的国内外重大活动以及政府的政策,措施,法令等重大事件,政府的社会经济发展计划,经济政策的变化,新颁布法令和管理条例等均会影响到股价的变动
Affect stock price factor Affect stock price changes by many factors, but basically can is divided into the following categories: market internal factors, fundamental factors, policy factors. (1) the market internal factors, it mainly refers to the market supply and demand, namely financing area and the relative proportion chips, such as certain stages of the stock market expansion rhythm will become the factors important parts. (2) fundamental factors include macroeconomic factors and internal factors, macroeconomic factors that can influence the market is mainly in stock prices of factors, including economic growth, economic cycle, rates, budgetary revenues and expenditures, money supply, price, international payments and so on, our company internal factors mainly refers to the financial position of the company. (3) policy factor is enough to affect stock price changes of important domestic and international activities and government policies, measures and laws to major events, the government's social and economic development plan, economic policy changes, the newly issued decrees and regulations etc all can affect stock price changes
影响股票价格重要经济因素
股票价格是指在证券市场上买卖股票的价格。实际上股票只是一种凭证,本身并没有价格,它之所以具有价格,能够在市场上进行买卖,是因为它可以给持有者带来股息收入。股票内在的价值的大小取决于未来预期实现盈利、贴现率和未来反复的年限。企业未来盈利越多,其现值越大,股票价格也越高,而贴现越高,股票内在价值就越低,股票价格也越低。所以,在西方股票市场上,人们都密切注视着企业未来盈利的状况。但事实上,股票价格的确定十分复杂,因为人们对一个企业未来盈利状况的看法并不全相同,有估计得比较悲观,股票在他们眼里的价值就低些,就要卖出;有的认为企业有发展的希望,股票在他们眼里价值就高些,就要买进。当买者多于卖者时,股票的价格就上升;当买者少于卖者时,股票的价格就下跌。所以,股票的市场价格与内在价格更多的时候表现为一致,投资者往往寻找那些内在价值大于市场的股票。
这样以来,就使股票的市场价格处于不断变化之中。它不仅要受各种经济因素的影响而且要受政治局势、政府政策、投资者心理、报刊杂志的消息以及谣言等社会因素的影响。下面着重分析一下影响股票价格的主要经济因素。
Affect stock price important economic factor Stock price "means in the stock market of stock price. Actually the stock is a certificate, does not itself, it is the price has price in the market, can be traded, because it gives the holder bring dividend income. Stock inner value depends on the size of the realization of the expected future earnings, the discount rate and future repeated the fixed number of year. Enterprise future earnings, the more its present value, the greater the stock price is higher also, and discount, the higher the stock intrinsic value will be lower, and stock prices also lower. So, in the west, people in the stock market is closely watched enterprise future earnings situation. But in fact, the determination of stock price is quite complex, because people to an enterprise future profitability opinion is not all the same, has an estimated more pessimistic, shares in their eyes the value of some lower, will sell, Some think the enterprise have the hope for the development of stock in their eyes, value as some taller, will buy. When buyers than sellers, stock prices went up, When buyers less than sellers, stock prices will fall. So, the price of stock market and inner price more of the time performance is consistent, investors tend to seek those intrinsic value than market shares. Since such, you will make the price of stock market is constantly changing. It should not only affected by various factors that influence the economic and political situation, by government policy, investor psychological, magazine, newspaper, news and rumors of social factors influence. Below are emphatically analyzed the influence of stock prices main economic factors.
一、股息
投资者之所以购买股票,是因为它能带来不低于存款利息的股息。股份公司发行股票的数量,不是取决于它的实际资本拥有量,而是取决于股息的派发量。股息越高,购者越踊跃,股票的价格也越高。但是,股息的增加又取决于企业收益的增长。如果企业发行股票的数量增加了,而增资后的利润却为同步增长,股息将无法维持原有水平,必然要减少,股票价格也会随之下降。欧美国家的一些企业,为了不断发展业务,使企业收益日益增长,把公司的净利润大部分或全部留下,以扩大资本积累,用于生产和经营,只发放少量股息或不发放股息,并且,国家在税收制度上也积极整套这样伏。由于企业的股票以即使不发或少发股息,这种股票对投资者也仍有很大的吸引力。
A, dividends Investors had to buy shares, because it can bring not less than deposit interest of dividends. The number of shares of the company shares, not depend on its actual capital ownership, but on the dividend amount distributed. The higher the dividend, buy more enthusiastically, the price of a stock is higher also. But, dividend increase depends on enterprise earnings growth. If the number of shares issued by companies increased, and add endowment hind profits but for increased dividends will not be maintained original level, it's necessary to rece, stock price also is met subsequently decline. Some of the enterprise, European and American countries for continuous development business, make the business income increasing, the company's net income all or most left, in order to enlarge capital accumulation, for the proction and operation, only a few dividends or not issue stated dividend, and national taxation system also actively package of such volts. Because enterprise stock to even not hair or less dividend, stock to send the investor is still very attractive.
二、金融资本和税收
股份公司常常向银行借款,随着借款额的增多,银行对企业的控制也就逐渐加强并取得了相当的发言权。在企业收益减少的情况下,虽然他们希望能够稳定股息,但银行为了自身的安全,会支持企业少发或停发股息,因而影响了股票的价格。税收对投资者影响也很大,投资者购买股票是为了增加收益,如果国家对某些营利事业在税收给以优惠,那么就能使这些企业的税后利润相对增加,使它们的股票升值。
Second, financial capital and revenue Joint-stock company often borrow from Banks, with the loan sum increase, bank of enterprise control also graally strengthened and made it quite claims. In the business income decrease case, although they hope to stabilize dividend, but bank for his own safety, will support enterprises or hair hair less dividend, thus affecting the stock prices. Tax on investors are significantly affected, investors buy stocks for increases the income, if the country for some profit-seeking enterprise in tax give preferential, then can make the enterprise's after-tax profits relative increase, make their stock appreciation.
三、经济周期
在经济繁荣时期,企业盈利多,股息高,股票则猛涨;在经济危机时期,企业生产萎缩,股息下降,股价则猛跌;在经济萧条时期,股价渐有转机;在进入复苏时期后,股价又开始上涨。所以,资本主义股票价格的变动,一般是与资本主义经济周期相适应的。
Third, economic cycle In the economic boom, corporate profits, dividends, stock is soaring high, In the economic crisis periods, enterprise proction decline, stock dividend atrophy, is tumbled, In the economic depression, share price graally a swift, Before entering the recovery period, prices began to rise. So, capitalism stock price movements are generally capitalism and adapt to the economic cycle.
四、通货膨胀
社会货币供应量的增减是影响股票价格的原因之一。通常,货币供应量增加,社会一部分闲置资金就会投向证券交易,从而抬高股价;相反,货币供应量减少,社会购买力降低,股价也必然下跌。由货币供应量不断增大而导致的通货膨胀,在一定限度内对生产有刺激作用,因为它能促进企业销售收入和股票投资名义收益的增加,所以在银行利率不随物价同比例上升的条件下,人们为了保值,将不再热心于存款,而转向投资股票,使股票价格再提高。但是,如果通货膨胀上升过猛,甚至了超过两位数,那么将造成人们实际收入下降和市场需求不足,加剧生产过剩,导致经济危机,使股票价格下跌。
Four, inflation Social money supply and decrease of stock price is to influence factor. Normally, the money supply increase, and the society of idle fund will to securities trading and thus increase share, Instead, money supply decrease, social purchasing power is reced, stocks also inevitable decline. By increasing the money supply to inflation, within limits to proce a stimulating effect, because it can promote the enterprise sales revenue and stock investment income increase, so the name in bank interest rates are with the price with ratio rose, under the condition of people to value, will no longer eager to deposit, and turned to invest in stocks and shares to raise price again. But, if inflation rising vastly, even more than two digits, so will cause people to real income decrease and market demand, aggravate overproction, cause economic crisis, make share prices.
五、贴现率与利率
贴现是银行放款的一种形式,贴现率与存款利率有密切的联系。存款率越高,贴现率也越高。由于股票的价格与企业未来预期盈利成正比,与贴现率(利息率)成反比,所以贴现率(或利息率)的提高,会导致股票价格的下降。但西方国家往往在银行利率上升时,股票市场依然活跌,原因是投资者常常在两者之间选择:银行存款风险小,利率高,收入稳定,但不灵活,资金被固定在一段时间内不能挪作他用,并且通俗读物以抵销通货膨胀造成的损失。而股票可以买卖,较为灵活,风险虽大,但碰上好运,可获大利。所以,在银行利率提高的情况下,仍然有一些具有冒险精神的投资者热心于股票交易。
Five, the discount rate and interest rate Discount is a form of bank lending, the discount rate and deposit rates are closely linked. Deposit rate is high, the discount rate is higher also. Because the price of the stock and the enterprise the expected future earnings is proportional to the discount rate (interest) is inversely proportional to the discount rate (or interest rates, so the promotion of, will lead to stock price falls. But in western countries have often bank interest rate rises, the stock market is still alive, reason is that investors often dropped in between choice: bank deposit small risk, higher interest rates, the income is stable, but not agile, the fund was fixed in a period of time inside cannot be used for other purposes, and popular literature to offset the loss caused by inflation. Stock can be bought, more flexible, though large, but the risk can be awarded with good luck, Italy. So, in the case of higher bank interest rate, there are still some adventurous investors keen on stock trading.
六、科技发明
在产业结构调整和转移时期,新产品的开发显得越来越重要,股价也会受到它们的强烈冲击。
新产品从开发完成至股价下跌这段时间,可分成三个阶段:
1、当消息传出以后,成了热门话题,此时股价自然会上扬,尤其一旦有人用投机手段,则更容易暴涨。
2、已经成为人们争相投资的对象,而这种新发明要普及化,需要很长时间,届时还销不出去的话,股价便会下跌。
3、假如新发明能够提高公司的业绩和利润率,股价会上涨,若没有预期效果,则跌幅很大。
因此,股票交易者必然充分注意这种规律,牢牢掌握股价的主动权。
Six, technological invention In the adjustment of instrial structure and the transfer of The Times, new proct development is becoming more and more important, share price is also under their strong impact. New procts from development completed to share fall this period of time, can be divided into three stages: 1 and when the news spread later, became a hot topic, when share prices will naturally rise, especially when someone with speculative method, then more easily boom. 2, has become people rushed to the object, but this kind of investment to popularize new invention, takes a long time, when we pin not go out, share price will decrease. 3, if new invention can improve the company's sales and profitability, price will rise, if do not have expected effect, then drop greatly. Therefore, stock traders must full attention to such laws, grip shares of the initiative.
