Democratic leadership is the best leadership style for today essays

Democratic leadership is the best leadership style for today essays Democratic leadership style is the advisable leadership style which encourages participation in decision-making and it can be persuasive or consultative. However, there is no best leadership style because nothing can be absolute right and comprehensive. In this assignment, I will illustrate the successful case about GLANZ GROUP which adopted autocratic leadership style in the beginning of its foundation. Furthermore, I will also show the successful cases by adopting democratic leadership or combination the different leadership styles in their company in order to support to my opinion. The cases from the books and from internet will also be illustrated. Strong leadership, no matter how well intentioned and benevolent, can foster dependency and subvert democracy. Yet absence of any leadership will lead to confusion, drift, and tension. As many progressive activists have remarked, there can be a "tyranny of structurelessness" as well as of autocracy. Mr. Qinde leung, Chairman of the board of directors and CEO of GLANZ GROUP who built up his own factory using 300 thousand RMB in 1978: Guizhou Feather and Down Factory, the former one of GLANZ GROUP. Soon after, he quickly realized that it was more beneficial for these down stream enterprises which used their products for further dress business. He decides to do the same business without any techniques and any skillful persons at that time. It was a big risk so that a lot of employees were against this plan. But Mr. Leung insisted on his own schedule and finally he got complete success depending on his own experience and special views. It cant be denied that at the developing stage of the company, facing the complicated situation and unbalanced quality of employees, Mr. Leung had to mange his company in autarchy. With the revolution of modern enterprises system in 1990, Mr. Leung became the CEO of GLANZ GROUP, his decision was un-challenged, but luckily, he has the spe...

Léon Foucault, Physicist Who Measured Speed of Light

Là ©on Foucault, Physicist Who Measured Speed of Light French physicist Là ©on Foucault played an essential role in measuring the speed of light and proving that Earth rotates on an axis. His scientific discoveries and contributions remain significant to this day, particularly in the field of astrophysics. Fast Facts: Là ©on Foucault Born: September 18, 1819 in Paris, FranceDied: February 11, 1868  in Paris, FranceEducation: University of ParisOccupation: Physicist Known For: Measuring the speed of light and developing the Foucault pendulum (which proved Earths rotation on an axis) Early Life Là ©on Foucault was born to a middle-class family in Paris on September 18, 1819. His father, a well-known publisher, died when his son was only nine years old. Foucault grew up in Paris with his mother. He was frail and often sick, and as a result he was educated at home until he entered medical school. He decided early on that he couldnt handle the sight of blood, and so left medicine behind to study physics. During his work with mentor Hippolyte Fizeau, Foucault became fascinated with light and its properties. He was also intrigued by the new technology of photography being developed by Louis Daguerre. Eventually, Foucault began to study the Sun, learning about the physics of sunlight and comparing its spectrum to that of other light sources such as lamps.   Scientific Career and Discoveries Foucault developed experiments to measure the speed of light. Astronomers use the speed of light to determine the distances between objects in the universe. In 1850, Foucault used an instrument developed  in partnership with Fizeau- now known as the Fizeau-Foucault apparatus - to prove that the once-popular corpuscular theory of light was not correct. His measurements helped establish that light travels slower in water than in air. Foucault continued improving his equipment to make ever-better measurements of light speed. At the same time, Foucault was working on an instrument that became known as the Foucault pendulum, which he devised and installed at the Pantheon de Paris. The large pendulum is suspended overhead, swinging back and forth all day in a motion known as oscillation. As Earth rotates, the pendulum knocks over small objects placed in a circle on the floor underneath it. The fact that the pendulum knocks over these objects proves that Earth rotates on an axis. The objects on the floor spin with the Earth, but the pendulum suspended overhead does not. Foucault was not the first scientist to build such a pendulum, but he brought the concept to prominence. Foucault pendulums exist in many museums to this day, providing a simple demonstration of our planets spin. The Foucault pendulum in the Pantheon de Paris. Public domain Light continued to fascinate Foucault. He measured polarization (the geometry of light waves) and improved the shape of telescope mirrors in order to properly light. He also continued to strive to measure the speed of light with greater accuracy. In 1862, he determined that the sped was 298,000 kilometers per second. His calculations were quite close to what we know as the speed of light today: just under 300,000 kilometers per second.   Later Life and Death Foucault continued to carry out his experiments throughout the 1860s, but his health deteriorated. He developed muscular weakness and had difficulty breathing and moving, all signs of what could have been the degenerative disease multiple sclerosis. He was also reported to have suffered a stroke the year before his death. There have been some suggestions that he suffered from mercury poisoning after being exposed to the element during his experiments. Là ©on Foucault died on February 11, 1868, and was buried in the Montmartre Cemetery. He is remembered for his wide-ranging and influential contributions to science, particularly in the field of astrophysics.
