When Cultures Collide - Mergers and acquisitions has become an important part of the American commerce, which communication plays an important role in reducing the negative impacts. While Schweiger agrees that failure to communicate with employees during a merger will increase employee uncertainty and anxiety, he highlights that previous researchers (Napier et al., 1989) did not measure uncertainty nor any of the supposed dysfunctional outcomes said to follow uncertainty. Communication is also suggested by others to be avoided, as it might alert competitors or cause employees to leave an organization rather than endure painful changes (Buono & Bowditch, 1989)....   [tags: mergers, acquistions, american commerce]

Threads, Quanta, and Technostuff: Theory of Loop Quantum Gravity - Threads, Quanta, and Technostuff The Theory of Loop Quantum Gravity is the lone, valid competition for the Superstring Theory. This theory quantifies Einstein’s Theory of Relativity by breaking down spacetime into sections called quanta at the Plank Scale. The Plank Scale, named after Max Plank, is the absolute most minuscule, microscopic measurement in the fabric of spacetime that physicists can only dream to observe. At this level, the very large and very small collide in what is known as quantum gravity....   [tags: Physics, Creation] 841 words

Using the Laws of Physics to Decrease Car Collisions - Every year, thousands of people lose their lives in car crashes. There are many factors that come into play when a car collision occurs, however only one factor stays constant throughout every single collision, and that is the laws of physics. The laws of physics are the fundamental base of understanding the world we live in, but unfortunately many people seem to be completely oblivious to them. A lot of the time, we try to deny our ignorance to physics but usually end up proving the opposite. For example, how believable is it that someone could have any knowledge of the physics in cars and have a pet and their lap while driving....   [tags: reconstruction, collision, momentum, force] 1369 words

Gas: The Kinetic Molecular Theory - Gas is one of three states of matter. The gas state is composed of a group of molecules that move freely, independent of each other. There are certain properties that define gas and separate the state of matter from the other two states: solid and liquid. Many different energies, forces, and amounts greatly affect the behavior of any type of gas. These differences consist of pressure, temperature, volume and even the number of molecules of a gaseous element. There is a mathematical relationship between all of these properties that affect all the properties when only one is changed....   [tags: Boyle and Charles Laws] 1245 words

Myriad Details of Black Holes - Introduction Definition: Black holes are rapidly spinning stellar bodies of incredible mass. A typical black hole has a mass many times that of our own sun , but the size approaches point density. For all intents and purposes, black holes are singularities, a fact that many physicists find contradictory, since in general the universe abhors a singularity. They are formed when a large sun exhausts its fuel and collapses to a very small volume. Of course, conservation of angular momentum and mass hold true, so as the star shrinks, it rotates faster and faster, and its density becomes greater and greater....   [tags: physics science space] 1520 words

Rates of Reaction - Rates of Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to collide with each other in order to react. However, they do not react if they collide without sufficient energy, and therefore the more energy a particle has, the more likely it is to react. The activation energy is the minimum amount of energy required by a particle in order to react....   [tags: Papers] 733 words

The Merging of Galaxies - A dwarf galaxy is, “a small galaxy composed of up to several billion stars—a smaller amount compared to our own Milky Way’s Galaxy’s 200-400 billion stars” (Wikipedia). On February 23, 2014, it was reported that two galaxies that had once orbited around the Andromeda Galaxy were merging together. The collision created a stream of stars in one of Andromeda’s dwarf galaxies, Andromeda II. Researchers then observed the stream of stars by separating them into categories and trying to analyze which could be members of Andromeda II versus those that could be “dwarf foreground stars from the Milky Way halo” (Amorisco et al, 2014, p 4)....   [tags: Astronomy, Universe] 713 words
