Free Essays on Emma Goldman

Emma Goldman was a major figure in the history of American radicalism. â€Å"She received fame for her advocacy of both free thought and anarchism† (Emma Goldman†). She was a courageous and outspoken anarchist, as well as one of the greatest radical propagandists in the United States (â€Å"Emma Goldman†). Along with being an exceptional propagandist, Goldman was also a good organizer who campaigned for more than thirty years to define the limits of dissent and free speech during the Progressive American era (â€Å"Emma Goldman†). During the period in which she lived, expressing controversial view points were dangerous, especially for women. Many people considered her ideas to be radical and dangerous, for example she opposed involuntary military service because she believed in free choice in all aspects of life (â€Å"Emma Goldman†). Goldman also believed that a campaign to prepare for war would result in a militarized America. Furthermore, she argu ed that a complete transform of social and economic values were needed. In Goldman’s â€Å"Patriotism: A Menace to Liberty† she says, â€Å"patriotism requires allegiance to the flag, which means obedience and readiness to kill father, mother, brother, sister† (179). Patriotism, as described by Oxford American Dictionary is â€Å"love of country; devotion to the welfare of one’s country; the passion which inspires on to serve one’s country†. Furthermore, being a patriot as defined by Oxford American Dictionary is, â€Å"one who loves and defends his or her country†. Because Goldman was a radical and an exceptional propagandist she describes loving or taking pride in ones country as a willingness to kill your family for the good of the country. Moreover, Goldman’s radical view points on how the United States military funding is too much and actual size of the military is too big. The United States of America is a nation created by war; the first war was the French and Indian war when wha...

The Coffered Ceiling in Architecture and Your Home

The Coffered Ceiling in Architecture and Your Home A coffered ceiling is a pattern of indentations or recesses in an overhead surface. In architecture, a coffer is a sunken panel in a ceiling, including the interior surfaces of domes and vaults. If a surface is coffered, it is not smooth. The architectural detail has been popular since Renaissance architects imitated Classical Roman techniques. Modernist architects often play with the depth and shape of the coffer. Key Takeaways: Coffered Ceilings A coffered ceiling is a series of indentations or hollows on the surface of a ceiling. Coffered ceilings decoratively hide ceiling imperfections and create the illusion of height. Historically, the design is considered dignified and formal.Simple coffered ceilings are created by crisscrossing beams that create geometric patterns, usually squares or rectangles. The word coffer comes from the ancient Greek word kophinos, which means basket. The Latin word for basket, cophinus, was adopted by the old French to mean various types of hollowed containers. The words coffer, a chest or strongbox to hold money, and coffin, a box for the dead, are both French derivations. The Latin word capsa, meaning box, evolved into the words caisson (an ammunition chest) and casket (same as coffin). Caisson ceiling is another term used to describe this type of ceiling hollow. The Chinese name for this type of ceiling, zaojing, means a well for plants that grow in water. The Latin word lacus, meaning lake or basin of water, is also used for this type of sunken panel (lacunar) ceiling. Coffers have been used in ceilings for centuries. Sometimes they were used to disguise the architectural engineering, where one beam or brace would be structurally necessary but others were built neaby for visual symmetry and to hide the necessary beam. Although hollows are sometimes used for structural weight distribution, coffers have always been used decoratively. Historically, a coffered ceiling can make a room look larger and more regal, as it does in the Palace of Versaille. Coffered ceilings are sometimes called caisson ceilings, plafond caissons, lacunaria, cross-beamed ceilings, and zaojing. Sometimes the English refer to these ceilings as coffer ceilings but never cougher ceilings. Coffered ceilings are found throughout architecture, from the Pantheon in Rome to the mid-century modern residence called Sunnylands at Rancho Mirage, California. The architect of Sunnylands used coffers inside and outside, to visually connect interior spaces with the outdoors. Exterior Detail at Sunnylands. The Greater Southwestern Exploration Company via flickr.com, Attribution 2.0 Generic (CC BY 2.0) cropped Coffers are not to be confused with latticework, a particularly important element in Islamic architecture. Like coffers, lattice is created with crisscrossed building materials, often pieces of wood, but lattice is arranged in decorative patterns to allow air through screens and windows, as in mashrabiya and jali. Coffered ceilings also should not be confused with the popular tray ceilings found in many large suburban homes. A tray ceiling is often a feature that enlarges a small kitchen or dining room without manipulating the footprint of the room. A tray ceiling has one, large sunken area in the ceiling, like one coffer, or an inverted tray. Creating Coffers Coffers are the sunken geometric areas in a ceiling, but most ceilings begin as a flat surface. Where do the coffers come from? Coffers can be created in at least two ways: (1) place a roof beam or crossbeam framework that naturally creates a space between the beams - the space appears sunken because the beams protrude; or (2) remove ceiling material, as you would carving a hole, or press into a flat surface to create an indentation, as you might create a sunken imprint into uncured concrete. Choosing the first method will take away ceiling height. Choosing the second method gains extra space for the rooms overall volume. Most coffered ceilings are created using the first method carried out in different ways. Unfinished Coffered Ceiling. Brian Moloney The Finishing Company Richmond via flickr.com, Attribution 2.0 Generic (CC BY 2.0) cropped Creating the design framework can be handcrafted by a carpenter like Brian Moloney, owner of The Finishing Company in the Richmond, Virginia area. Maloney is a finish carpenter, but that doesnt mean he comes from Finland. In fact, he comes from Ireland. Finishing is just one of the many carpentry skills of a master carpenter. Coffered Ceiling Built by Brian Moloney, Finish Carpenter from Ireland. Brian Moloney The Finishing Company Richmond via flickr.com, Attribution 2.0 Generic (CC BY 2.0) cropped An easier drop ceiling method is often used by commercial developers, manufacturers, and do-it-yourselfers (DIYs). Companies such as Classic Coffers can be hired to install a grid (sometimes beneath a fixed ceiling), then the panel coffers are placed within the grid. These arent the tacky looking drop ceilings of your grandmothers basement. A coffered drop ceiling can be created to look exactly like the wood finishing of a master carpenter. Only Brian Moloney could tell the difference. The DIY may buy a box of polystyrene foam tiles - faux tin like tiles - that purportedly can be installed right over Pop Corn ceiling. Its your choice. A less well-known method of creating coffers is offered by none other than Michelangelo. The Renaissance master manipulated the illusion of space with trompe loeil, a painting technique that tricks the eye into believing a certain reality. Michelangelo used his artistic skills to paint many of the three-dimensional moldings and crossbeams, creating the illusion of coffers in the most famous ceiling of all time, the Sistine Chapel in Vatican City, Rome. Which is wood and which is paint? Detail of Sistine Chapel Ceiling by Michelangelo. Fotopress/Getty Images (cropped) Photo Credit Tray Ceiling, irina88w/Getty Images

Domestic Terrorism Essay Example | Topics and Well Written Essays - 750 words - 1

Domestic Terrorism - Essay Example The burning of churches, houses, and farms, and animals and property, as well as the lynching of human beings is without question cowardly and sociopathic, but had these acts been committed by individuals living in a jurisdiction in which their crimes were not just excused by the highest echelons of local jurisprudence, but actually extolled as a method of preserving the fabric of society and the foundation of liberty and democracy, those actions would lost their truly tragic dimension. That tragic dimension is expressed in the concept of a continuing pattern that would never have been stopped without the intervention of outside forces. Part of the tragedy engendered by the Klan’s willingness to murder, burn, and intimidate is expressed in the movie: the passage of ignorance and fear from generation to generation. That the violent activities engaged in by the Ku Klux Klan qualify as terrorism is without question. The Klan burns down a farm purely for the purpose of intimidation. The fact that the fire kills valuable horses as well as other property and that no money or items are stolen indicates the motivation. Terrorism is defined by nothing else more than motivation. If terrorism can be defined as acts of violence intended to maintain or change a system of social order, then clearly the murders, fires and collusion of protection offered by the sheriff’s department and the local judge indicates that terrorism is exactly what is taking place in among the white residents of the Mississippi town that is the setting of the film. If it can be determined that the specific actions of lynching, beating, and destruction of property were committed to ensure that black residents could not exercise their right to vote because the implicit assumption would be that they would cast their vote in an effort to change the social order of a segregated

Mali Empire and New World Encyclopedia Essay Example for Free

Mali Empire and New World Encyclopedia Essay Timbuktu was established by the Taureg, a nomadic group, in the tenth- eleventh century along the caravan routes that were along the west coast of Africa (New World Encyclopedia 2007). Timbuktu was in a good spot for trade but not for defending against attacks, and Timbuktu was constantly attacked by Taureg raiders (New World Encyclopedia 2007). Timbuktu was never able to grow due to the raids, but Gao, Timbuktu’s neighboring city grew to be the political capital (New World Encyclopedia 2007). As Timbuktu developed and became a city that traded gold, ivory, slaves, and salt Timbuktu became immensely wealthy (New World Encyclopedia 2007). Since Timbuktu was so wealthy it was a target for many European empires seeking wealth (New World Encyclopedia 2007). It started to decline in the 16th century by the Portuguese traders choosing to send the goods upriver instead of down river (New World Encyclopedia 2007). As Timbuktu developed into a more intellectual center in the early 15th century it became known for its religious study of Islam (New World Encyclopedia 2007). While Islam was the main religion of Timbuktu, most of the rural population were non-Muslim traditionalists (New World Encyclopedia 2007). The University of Sankore, also known as the most prominent Islamic institution, was established in 1581 C. E. and taught mostly centered around the Qur’an (New World Encyclopedia 2007). In Timbuktu there were more than 120 library’s in which housed millions of books, and some of which have not been found yet (New World Encyclopedia 2007). As stories of Timbuktu’s wealth reached Europe many explorers journeyed downward into Africa to have their own taste of the wealth (Timbuktu: The El Dorado of Africa 2013). As countless European explorers journeyed to Timbuktu and never returned The Geographic Society of Paris offered a reward to whatever explorer that could make it there and 2 back and live to tell the tale (Timbuktu: The El Dorado of Africa 2013). The first explorer to reach Timbuktu was Gordon Laing in 1826, but he didn’t make it back alive (Timbuktu: The El Dorado of Africa 2013). The first explorer to reach Timbuktu was Rene-Auguste Caillie in 1828, by disguising himself as an Arab traveling in a caravan (Timbuktu: The El Dorado of Africa 2013). When Rene returned to Europe he wrote three volumes over how unimpressed he was about the city in that it being a mud-walled city, in the middle of the desert, and not having any gold (Timbuktu: The El Dorado of Africa 2013). Although in 1512 when Timbuktu was at its peak and Leo Africanus visited he stated: The rich king of Tombuto hath many plates and sceptres of gold, some whereof weigh 1300 pounds He hath always 3000 horsemen (and) a great store of doctors, judges, priests, and other learned men, that are bountifully maintained at the kings expense. (New World Encyclopedia 2007) Although from Shabeni’s point of view of Timbuktu in 1787 he stated: On the east side of the city of Timbuctoo, there is a large forest, in which are a great many elephants. The timber here is very large. The trees on the outside of the forest are remarkable they are of such a size that the largest cannot be girded by two men. They bear a kind of berry about the size of a walnut, in clusters consisting of from ten to twenty berries. Shabeeny cannot say what is the extent of this forest, but it is very large. (New World Encyclopedia 2007) In 1591 Timbuktu started to slowly decline due to the Morisco mercenaries armed with guns (New World Encyclopedia 2007). One of the few reasons Timbuktu is still in existence is 3 because it is a major tourist attraction that attracts people from all over the world to see the mystical city (New World Encyclopedia 2007). 4 Alistair Boddy-Evans (2013).

Women Have the Right to Choose Abortion Essay -- Papers Argumentative

Women Have the Right to Choose Abortion An abortion is a woman's option to terminate a pregnancy. It is an induced miscarriage. Abortion has become an extremely controversial topic in the past 3 decades since it has been legalized. There has been extreme violence stemming from this issue that we as a country need to put under control, regardless of our personal stances on the issue. There are many reasons why a woman would choose to have an abortion. She does not feel she is ready to be a parent, she can not afford a baby, and being too young or immature to be responsible for another life are only three of these reasons. If a woman becomes pregnant due to a rape or from incest would be another reason. It has been found that almost fifty per cent of all women will have an abortion by the time they reach 45. Is this number increasing since the legalization of abortion? Probably not, considering the fact that before abortions were legal they were still being preformed. The only difference is now they are safer. Before 1965, abortion was somewhat taboo. No one dared to even discuss the issue. Abortion was frowned upon and considered "evil"; therefore it remained a very private issue. Abortions were performed by doctors, nurses, midwives, even chiropractors. Being that abortions were not performed in a hospital or clinic, anyone who felt like it could become an abortionist. These abortions were referred to as back- alley abortions. They were unsafe and lead to the deaths of many women, but in 1933 it was estimated that nearly 2 million were performed (Grisey). This proves to us that regardless if abortion is legal or not, if a woman feels she needs to have one she is going to. The prices of thes... ... to an increase in child abuse and neglect. I am not encouraging the use of abortion as a method of birth control, but accidents will happen. Some people are responsible enough to deal with these accidents, but some feel that they are not ready to bring a child into this world. If a mother feels she can not properly care for a child, isn't it better for the fetus to be aborted before it is brought into a world where it can not be properly loved, cared for and supported?  Bibliography: Works Cited 1.

Sinusoidal Current Control Strategy Based Active Power Engineering Essay

Abstract- In this article describe the public presentation of a sinusoidal current accountant based three-phase shunt active power line conditioners ( APLC ) for power quality betterments such as harmonics and reactive power compensation due to imbalanced and non-linear tonss. The electromotive force deformations are compensated by positive-sequence electromotive force sensor and harmonic extracted from changeless instantaneous existent power control scheme, this attack is different from the conventional methods. The shunt APLC is implemented with PWM current controlled electromotive force beginning inverter and connected to the point of common yoke for extinguish the current harmonic and do sinusoidal current to the beginning. The mention current ( s ) are extracted from sinusoidal current accountant algorithm and PWM-VSI gate control signals are generated from hysteresis current accountant ( HCC ) . The relative integral ( PI ) -controller used to keep the changeless DC-side electr ical capacity electromotive force of the PWM inverter. The shunt APLC is investigated in footings of order of harmonics, VDC subsiding clip and assorted parametric quantities under the assorted non-linear burden conditions. Keywords- Shunt Active Power Line Conditioners ( APLC ) , Hysteresis Current Controller ( HCC ) , Sinusoidal current accountant, Positive sequence electromotive force sensor.IntroductionPower transmittal and distribution systems are criticized by power quality jobs due to the non-linear tonss, such as power convertors, rectifiers, arc furnaces and other industrial applications like variable velocity thrusts. These non-linear tonss introduce harmonic deformation in the power distribution system [ 1 ] . The current harmonics cause the malfunctions in sensitive equipment, overvoltage by resonance and harmonic electromotive force bead across the web electric resistance that consequence is hapless power factor. Traditionally these jobs were solved by LC inactive filters. But in practical applications these inactive filters introduce aging and tuning jobs, resonance, big size and it ‘s besides limited to few harmonics. The different constellations of inactive VAR compensators ( SVCs ) have been participated for solve these jobs of power-factor rectification. Unfortunately some SVCs produce lower-order harmonics themselves and response clip of some SVCs may be excessively long to be acceptable for fast-fluctuating tonss [ 2-3 ] . Recently active power filters ( APF ) or active power-line conditioners ( APLC ) are developed for compensate the current-harmonics and reactive power at the same time due to power factor rectification [ 4 ] . The APLC has the ability to maintain the brinies current balanced after counterbalancing regardless of either the burden is non-linear and/or imbalanced conditions. The APLC can be connected in series for operate as electromotive force beginning and in analogue for operate as current beginning, but the series APF is non found in common practical usage, so this paper concentrate the shunt APLC system [ 5 ] . Controller is the sole of the active power filter and presently batch of research is being conducted and proposed assorted control schemes [ 6-7 ] . The sinusoidal current accountant algorithm is widely applied for active filter design, because simple mathematical computation, hardiness and good dynamic response. This accountant contains of positive sequence electromotive force sensor and instantaneous power theory ( p-q theory ) concept [ 3 ] . The footing of instantaneous power theory is supplying good compensation features. Current harmonics is achieved by shooting equal but opposite current harmonic constituents at the point of common yoke ( PCC ) , there by call offing the original deformation and bettering the power quality on the connected power system. This paper presents sinusoidal current accountant based shunt APLC for current harmonics and reactive power compensation under non-linear and imbalanced tonss. The shunt APLC is implemented with three stage PWM electromotive force beginning inverter and connected to the Ac mains web at the point of common matching for compensate the harmonics by shooting equal but opposite harmonic counterbalancing current. The mention currents are generated utilizing sinusoidal current accountant and PWM-VSI gate control signals are derived from hysteresis current accountant, this attack is different from conventional methods. The Proportional Integral ( PI ) accountant used to keep the dc-side electrical capacity electromotive force of the PWM inverter invariable. The shunt APLC is investigated and measured assorted parametric quantity values under different tonss.Sinusoidal Current Control schemeShunt APLC system designShunt active power filter is connected in analogue with the distribution supply and the non-linear tonss at the point of common yoke. The three stage active power filter consist of six power transistors with drifting rectifying tubes, a District of Columbia capacitance, RL filter, compensation accountant ( sinusoidal current accountant ) and gate signal generator ( hysteresis current accountant ) shown in the fig 1. The mention current generated utilizing sinusoidal current accountant and this accountant contains the positive sequence electromotive force sensor and instantaneous power theory computations. The RL-filter suppresses the harmonics caused by the switching operation of the IGBTs inverter. Current harmonics is achieved by shooting equal but opposite current harmonic constituents at the point of common yoke, there by call offing the original deformation and bettering the power quality on the affiliated power distributed system.PWM-VSIHysteresis Current ControllerVDCVDC, refVsa, Vsb, Vscisa, isb, iscica, icb, Interstate Commerce CommissionRs, LsPCCFilt erisa* , isb* , isc*NitrogenUnbalanced burdenRL, LL3-Phase BeginningABacillusCRL LLCBacillusANon-sinusoidal LoadCurrentDetectorVoltageDetectorABacillusCGramPI ControllerVdc SensorInstantaneous Power theory computationSinusoidal current controlPositive sequence electromotive force sensorCDCFig 1 Shunt APLC implemented with PWM-VSI ConfigurationSinusoidal current control schemeThe block diagram of the sinusoidal current control scheme is shown in fig 2. This block contains the Positive sequence electromotive force sensor, PI accountant, Clarke transmutation, Instantaneous power computation, Low base on balls filter ( LPF ) , current computation and Inverse Clarke transmutation. The deformed or unbalanced electromotive force beginnings involved the cardinal positive sequence electromotive force sensor ( shown in fig 3 ) , which uses a PLL circuit ( shown in fig 4 ) locked to the cardinal frequence of the system voltages. It should synchronising angle to bring forth unitary and balanced sinusoidal electromotive force signals. These instantaneous 3-phase co-ordinate e lectromotive forces are transformed into the co-ordinates by utilizing the Clarke transmutation, it can be written as [ 3 ] The instantaneous beginning current besides transformed into the co-ordinates by Clarke transmutation ; Whereand axes are the extraneous co-ordinates and are on the-axis and are on the-axis. Let the instantaneous existent power calculated in the -axis and the -axis of the current and electromotive force severally. They are given by the conventional definition of existent power as follows: This instantaneous existent powerallows merely the cardinal frequence with the set of Butterworth design based 50 Hz low base on balls filter for calculate the existent power losingss and it ‘s defined as The DC power losingss calculated from PWM-voltage beginning inverter electrical capacity electromotive force and compared with coveted mention electromotive force.

If the mistake current is exceed the upper bound of the hysteresis set ( h=0.5 ) , the upper switch of the inverter arm is turned OFF and the lower switch is turned ON. As a consequence, the current starts to disintegrate. If the mistake current crosses the lower bound of the hysteresis set ( h=-0.5 ) , the lower switch of the inverter arm is turned OFF and the upper switch is turned ON. As a consequence, the current gets back into the hysteresis set. The scope of the mistake signaldi rectly controls the sum of ripple electromotive force in the end product current from the PWM-VSI.Consequence and analysisThe public presentation of the proposed sinusoidal current control scheme based shunt APLC is evaluated through Matlab tools in order to pattern and prove the system under non-linear and/or imbalanced burden conditions. The system parametric quantities values are ; Line to line beginning electromotive force is 440 V ; System frequence ( degree Fahrenheit ) is 50 Hz ; Source electric resistance of RS, LS is 1 ? and 0.1 mH ; Filter electric resistance of Rc, Lc is 1 ? and 0.5 mH ; Diode rectifier RL, LL burden is 20 ? and 200 mH ; Unbalanced three stage RL, LL burden electric resistance is R1=10 ? , R2=50 ? , R3=90 ? and 10 mH severally ; DC side electrical capacity ( CDC ) is 1200 ?F ; Reference electromotive force ( VDC, ref ) is 400 V ; Power devices build by IGBT/diode.

Give It Up vs. Applaud

Give It Up vs. Applaud Give It Up vs. Applaud Give It Up vs. Applaud By Maeve Maddox A reader asks, Lately, I hear announcers introducing acts by saying GIVE IT UP FOR, rather than   LETS HAVE A ROUND OF APPLAUSE FOR. Is this a new expression? The verb give/gave/given has been in the English vocabulary for more than a thousand years. The earliest OED citation is from Beowulf: Beowulf 1719 Nallas beagas geaf Denum à ¦fter dome. Note: The reference is to Heremod, a Danish king who did not honor his men by giving them treasure as custom required. A literal translation of this example is â€Å"Not at all rings gave [he] to the Danes for honor.† The OED entry for give requires more than a hundred items to clarify the various ways in which this verb is or has been used throughout the centuries. The expression â€Å"give it up for so-and-so† is just one of the verb’s more recent uses. The earliest OED citation for â€Å"give it up† in the sense of â€Å"applaud,† dated 1990, is from a Web source: Hey folks, lets give it up for Andy! One huge round of applause please!- Re: ShrinkIt 3.0 in comp.sys.apple2 (Usenet newsgroup). The basic meaning of give is â€Å"to make another person the recipient of something in the possession of the giver.† When an audience is asked â€Å"to give it up† for a speaker or performer, they are being asked to show appreciation by applauding. In this way, they give their approval. An earlier expression referring to the act of applauding links give with hand. At the end of Shakespeare’s A Midsummer Night’s Dream, Puck (aka Robin Goodfellow) asks for applause this way: Give me your hands, if we be friends: And Robin shall restore amends. Audiences are said to â€Å"give a hand† to performers. Performers hope to â€Å"get a big hand† from their audiences. No one seems to mind such established circumlocutions for applaud, but the latest expression provokes annoyance: Does anybody else hate the expression, â€Å"give it up† for whoever it is instead of just clapping? It drives me mad. Oh, I must say that I  hate  the recent,  Put your hands together for. Or the even more egregious,  Lets give it up for â€Å"Give it up† annoys me too. I hate this new age talk, it just sounds lazy. I hate â€Å"give it up for [so-and-so]† when announcers introduce entertainment acts. Love it or hate it, â€Å"give it up for† in the sense of â€Å"please applaud† has caught on with large numbers of speakers. Note to ESL learners: In some contexts, â€Å"give it up† or â€Å"give up† can also mean surrender, abandon, and quit: The house is completely surrounded. You might as well give it up. Eventually he took a huge risk and  gave himself up to  the Chicago  police. Unable to overtake the planes,  he gave up  the chase three miles from his own lines. How  many  people do something just once and are  ready to give up?   Give it up! You can’t win. Want to improve your English in five minutes a day?

9 Pieces of Celebrity Advice That Will Inspire You to Succeed in 2017

9 Pieces of Celebrity Advice That Will Inspire You to Succeed in 2017 Love them, hate them, or roll your eyes when you see them make news for ridiculous things, famous people have something in common: they’re good at what they do, or you probably wouldn’t know who they are. And while you probably shouldn’t, say, take medical advice from George Clooney or legal advice from Justin Timberlake, it’s worth seeing what kind of celebrity advice they have to offer. As we look to the new year with its blank slate, let’s also look at how some household names in business, Hollywood, and politics approach career, success, and life balance. On Finding Purpose and DirectionOne of the first things you should do in the new year is figure out what you  want your  goals to be. To do that, it’s important to figure out what motivates you, and what you really want to be doing with your professional life. A new year is a chance to take a look at what motivates you now, because that may not be the same thing that motivated you in the past. Take the opportunity to look at who you are now, and what forces are moving you forward.â€Å"Stop chasing the money and start chasing the passion. - Tony Hsieh, CEO of Zapposâ€Å"’May the Force be with you’ is charming but it’s not important. What’s important is that you become the Force- for yourself and perhaps for other people.† - Harrison Ford, actorOn Being Your Own Biggest AssetNot to get all sappy on you, but your best ally in this process is, well, you. Networks are important, but as you get ready to ramp up your career in the new year, make sure you’re putting enough value and emphasis on the skills, experience, and expertise that you already have. 2017 should be a year of moving forward with confidence, not stalling out due to self-doubt.â€Å"Don’t discount yourself, no matter what you’re doing. Everyone has a unique perspective that they can bring to the world. Just have faith in yourself and trust yo urself.† - Mark Zuckerberg, CEO of FacebookOn Achieving SuccessSuccess is not an instant result, no matter who you are or what you do. People who achieve that success have gotten there because they stuck it out, and threw everything they had at the process. CEOs, entertainers, thinkers†¦the version of â€Å"success† is different for each of them, but they have one thing in common: effort + time.â€Å"When I was 15, I left school to start a magazine, and it became a success because I wouldn’t take no for an answer.† - Richard Branson, CEO of the Virgin Groupâ€Å"There’s no such thing as overnight success. That’s my concern with a show like American Idol. It encourages the false belief that there’s a kind of magic, that you can be ‘discovered.’ That may be the way television works, but it’s not the way the world works. Rising to the top of any field requires an enormous amount of dedication, focus, drive, talen t, and 99 factors that they don’t show on television. It’s not simply about being picked. Which, by the way, is why very few of the anointed winners on American Idol have gone on to true success. Most have flamed out and gone away. That should tell us something.† - Malcolm Gladwell, authorâ€Å"Success is just a war of attrition. Sure, there’s an element of talent you should probably possess. But if you just stick around long enough, eventually something is going to happen.† - Dax Shepard, actorâ€Å"Do the work. Out-work. Out-think. Out-sell your expectations. There are no shortcuts.† - Mark Cuban, entrepreneurOn Why You Should Never Give UpIf you give up on your goals because you’re seeing too many challenges or it feels too hard, no one is going to run up to you, shouting, â€Å"come back! Just kidding, here’s what you want.† Once you figure out what you want to achieve and start devising your plan to get there, itâ₠¬â„¢s crucial to stick to that, whether things get tough or are taking longer than you thought they would. You’re tougher than you think you are, so don’t let setbacks deter you from those bigger goals.â€Å"I’m very glad my mother didn’t let me quit piano lessons at age 10. She said I wasn’t old enough or good enough to make that decision, and she was right. I remember at the time I was shocked. I did not like that my mother said those things to me. But when I got a chance to play with Yo-Yo Ma or more recently with Aretha Franklin, I thought, I’m really glad she said what she did.† - Condoleezza Rice, former Secretary of StateOn Seizing OpportunitiesIn 2017, be ready to size up and grab potential opportunities. Do research, talk to people in your network, and always keep an eye out for new jobs, new skill-building opportunities, anything that can help you along the way. If you’re not proactive, you’ll either miss poten tial opportunities entirely, or watch them slip right by you and turn into someone else’s chances.â€Å"People ask, ‘What’s the best role you’ve ever played?’ The next one.† - Kevin Kline, actorâ€Å"Put your head down and work hard. Never wait for things to happen make them happen for yourself through hard graft and not giving up.† - Gordon Ramsay, chef, entrepreneur, and TV personalityâ€Å"If I can’t make it through one door, I’ll go through another door- or I’ll make a door. Something terrific will come no matter how dark the present is.† - Joan Rivers, comedianâ€Å"I feel that luck is preparation meeting opportunity.† - Oprah Winfrey, entrepreneur and world dominatorOn Why It’s Okay to FailNobody likes failure- but it’s inevitable at some point. You know that song â€Å"Everybody Hurts,† by R.E.M.? The career version of it is, â€Å"everybody flops, sometimes.† Itâ₠¬â„¢s going to happen, it’s going to hurt, and you should be ready to take that failure and learn from it so you can keep moving forward. Don’t let minor failures derail your year of progress.â€Å"Failure is not the opposite of success; it’s a stepping stone to success.† - Arianna Huffington, founder of The Huffington Postâ€Å"Failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me. Had I really succeeded at anything else, I might never have found the determination to succeed in the one arena I believed I truly belonged.† - J.K. Rowling, authorOn Overcoming Career Obstacles2017 will have obstacles. That’s non-negotiable. But when you’re faced with those challenges, don’t let them stop your progress. Instead, ask yourself how they can factor into your journey.â€Å"When faced with sexism or ageism or lookism or even really aggressive Buddhism, ask yourself the following question, ‘Is this person between me and what I want to do?'† - Tina Fey, comedian and writerOn Why Being a Lone Wolf Doesn’t WorkIf you think your 2017 journey is all about you, you’re mistaken. You are the most important piece of it, yes. But being a good team member, and knowing when to rely on others is a skill that you should start practicing as early in the year as possible. It’s not just that others can help you directly (although many can); it’s just as much learning what you can from others to apply to your own professional life.â€Å"What I have discovered, is this: You can’t do it alone. As you navigate through the rest of your life, be open to collaboration. Other people and other people’s ideas are often better than your own. Find a group of people who challenge and inspire you, spend a lot of time with them, and it will change your life.† - Amy Poehler, comedian and writerâ€Å"I look for a positive attitude and are they easy to work with, are people gonna like working with them? It’s very important to like the people you work with, otherwise life [and] your job is gonna be quite miserable.† - Elon Musk, entrepreneur and CEO of Tesla Motors and SpaceXâ€Å"The best advice I ever got is: You’re the average of the five people you associate with the most.† - Tim Ferriss, author and entrepreneurOn Achieving Balance While Pursuing Your GoalsIf you have some aggressive professional goals in 2017 (new job, promotion, new approach to your existing job), don’t let those crowd out everything in your life. Making room for your personal growth, development, and happiness is just as essential. This may involve some creative thinking and sacrifices, but when you get to the other side of 2017, you don’t want to be thinking, â€Å"I wish I’d made time for thi ngs that make me happy.†Ã¢â‚¬Å"Believe you can do anything. This is important for everyone and especially for women. Don’t let anyone tell you can’t have both a meaningful professional career and a fulfilling personal life. When you hear someone say you can’t do something, know that you can and start figuring out how. Ask yourself, ‘What would I do if I weren’t afraid?’† - Sheryl Sandberg, COO of FacebookAs you gear up for 2017 and the banner career year you’re going to have (whether you’re looking for new opportunities or working on growing in the role you already have), think about these bits of advice given by people who’ve reached the top of their fields. And more importantly, think about how you can make these recommendations work for you, and seize your next great opportunity!

Role Of A Leader In Managing Crisis. Toyota case study Essay

Role Of A Leader In Managing Crisis. Toyota case study - Essay Example A leader’s primary role is to set the goals for the crisis management strategy which requires to be based on the organisation’s values. Leadership qualities are measured through the commitment involved in drafting crisis problem along with the firm’s top management. Further identifying the levels of problem related to crisis management will enable a leader to create a friendly and supportive environment in the organisation. The next step for the leader lies in identifying the team to lead the crisis management. The purpose of the team will be to identify the crisis in the organisation. The main role of the leadership here will lie in empowering the team and making the team competent to analyse the crisis by different components such as process, location, pressure, market place and industry (Goel, 2009, p. 247). The tertiary role of the leadership is to implement strategy leading to effective communication with both internal and external sources such as employees, stakeholders, partners, etc. Apart from this regular training to the employees regarding crisis management is another important aspect to measure the leadership attributes. External forces An organisation’s ability to identify external forces which can impact the internal environment of the organisation is an important mechanism related to crisis management. This requires the incorporation of scrutinising mechanism by the leadership to continuously analyse the external forces and convert them into values for the organisation and the members associated with it. ... Example: A hospital’s ability to foresee the impact of technology advancement and the ability to adopt the latest technology in its various departments can be adjudged as the modification in its internal atmosphere to convene the fundamental change in the external force related to technology (Porter-O’Grady & Malloch, 2010, p. 230). Internal forces Like external forces, the internal forces too have an impact on the organisation and its ability to adapt itself in the changing environment. It is important for the leadership to maintain a balance between work and process to be able to change the work mechanism as demanded by both internal and external forces. This concept of liveliness is very important for the leadership to understand the current dynamics of work. Example: Distribution channel of pharmacy, supply chain management of materials are the representatives of internal work structures and needs to change with the changing environment. Akio Toyoda’s respons e in related to the Toyota crisis can be examined in a more illustrated manner in the following manner: Dysfunctional organisation culture The leaders of Toyota are the main culprits as they are the ones responsible for the crisis. Akio Toyoda took the control of the organisation when it was not in best of shape; expert advice was often neglected over safety measures which ultimately had an impact on organisation. Crisis cannot always be spun Akio Toyoda made the mistake of taking the situation lightly and not paying much heed to the consequences. Instead of responding that the organisation is replacing the faulty parts and will keep doing the same in the near future, Akio Toyoda should have

Holographic Design Essay Example | Topics and Well Written Essays - 250 words

Holographic Design - Essay Example This is where the people are in the process of learning to see the organization as a whole (Senge, 1990). Organizational reality is linked to the understanding of uncertainty of the organizational environment by the key executives and their ability to drive the organization in a particular direction (Stacey, 2010). The concept of a learning organization is taken to the next level by a particularly organic approach to systems thinking (Hà ¤mà ¤là ¤inen & Saarinen, 2008). This emergent approach is called the Holographic design of an organization. The principles of the Holographic design (Morgan, 2006) are used hereunder to conceptualize the organization from a holographic perspective: The first principle of the holographic design represents the incorporation of the vision and values of the whole organization in to the individual parts. The principle directs organizations to integrate the above values into a corporate DNA and achieve a networked intelligence structure. The structure so achieved is has an inherent ability to duplicate itself. Wherein teams with holistic visions of the organization are created. The x organization can achieve a collective sensory perception of the vision and values and enable its employees to see things in individual and collective gaze as one. The second principle of Holographic design underlines the importance of redundancy in processing of organizational information and design of skill set and the work of the team members. The X organization can enable and encourage its employees to help discard old thinking systems and bring in fresh approach and thought processes. The third holographic principle emphasizes the requisite variety in the sense that internal complexity of an organization should be in consonance with the external variety. The X organization shall foster the inherent variety of ideas and capabilities of the members of the organization to match that of the external
