Distracted driving Essay Example for Free

Distracted driving Essay Introduction – Distracted driving is a growing and dangerous problem in today’s society that can lead to accidents causing injury and even death. Risk factors with distracted driving: Talking on a cell phone while driving Younger, inexperienced drivers under the age of 20 may be at increased risk; they have the highest proportion of distraction-related fatal crashes. There are three main types of distraction:  ·Visual: taking your eyes off the road;  ·Manual: taking your hands off the wheel; and  ·Cognitive: taking your mind off of driving. Statistics on distracted driving: 69% of drivers in the United States ages 18-64 reported that they had talked on their cell phone while driving within the 30 days before they were surveyed. In Europe, this percentage ranged from 21% in the United Kingdom to 59% in Portugal. Conclusion Mobile phones have immense public utility, improving communication in social and commercial interactions. Nonetheless, their role in driver distraction and consequently in road traffic crashes means that some measure of â€Å"reining in† their use while driving is required.

Gallium :: essays research papers

Gallium 1871 Dmitrii Ivanovich Mendelev predicts the existance and properties of the element after zinc in the periodic table. He Gives it the name "eka aluminium". 1875 Paul Emile Lecoq de Boisbaudran discovers gallium. Its properties closely match those predicted by Mendelev. Gallium, atomic number 31, is very similar to aluminum in its chemical properties. It does not dissolve in nitric acid because of the protective film of gallium oxide that is formed over the surface by the action of the acid. Gallium does however dissolve in other acids, and alkalies. Gallium was discovered (1875) by Paul Emile Lecoq de Boisbaudran, who observed its principal spectral lines while examining material seperated from zinc blende. Soon after he isolated the metal studied its properties, which coincided those that Dmitrii Ivanovich Mendelev had predicted a few years earlier for eka-aluminium, the then undiscovered element lying between aluminum and indium in his periodic table. Though widely distributed at the Earth's surface, gallium does not occor free or concentrated in independant minerals, except for gallite. It is extracted as a by-product from zinc blende, iron pyrites, bauxite, and germanite. Silvery white and soft enough to be cut with a knife, gallium takes on a bluish tinge because of superficial oxidation. Unusual for its low melting point ( about 30 degrees C, 86 degrees F ), gallium also expands upon solidification and supercools readily, remaining a liquid at temperatures as low as 0 degrees C ( 32 degrees F ). Gallium has the longest usefull liquid range of any element. The liquid metal clings to glass and similar surfaces. The crystal structure of gallium is orthorhombic. Natural gallium consists of a mixture of two stable isotopes: gallium-69 ( 60.4 percent ) and gallium-71 (39.6 percent ). Somewhat similar to aluminum chemically, gallium slowly oxidizes in moist air until a protective film forms, and it becomes passive in cold nitric acid. Gallium has been considered as a possible heat-exchange medium in nuclear reactors, although it has a high neutron cross section. Radioactive gallium-72 shows some promise in the study of bone cancer; a compound of this isotope is absorbed by the cancerous portion of the bone. The most common use of gallium is in a gallium scan. Gallium scans are often used to diagnose and follow the progression of tumors or infections. Gallium scans can also be used to evaluate the heart, lungs, or any other organ that may be involved with inflammatory disease.

Ethical Leadership – Analysis

Reader also used the â€Å"waiter rule† to explain that a lot can be said about a person's character by the way they treat the waiter, which is much like the golden rule, treat others as you wish to be treated. This piece of advice relates to the business world, because professionals should respect one another, tell the truth, and conduct themselves in an ethical manner. Furthermore, Reader discussed the leadership and ethical leadership. He described leadership as someone who inspires people to achieve a goal.He elaborated on this concept by stating that ethical leadership is when a person leads y Influencing their followers and use Input from the followers to shape goals and purposes. Moreover, an ethical leader should be consistent In both words and actions, lead by example, and can be referred to as a role model. These ethical leaders are extremely Important to employees. Reader shared some astounding statistics as to why employees need role models: 56% of employees person ally observed misconduct and out of those who observed it, 42% did not report it.This shows that the tone at the top is extremely important in firms. If the management is more likely to behave unethically, then this attitude trickles down and negatively effects the ethical values of everyone in the company. In addition, he discussed how peer commitment is important. For example, most times, an employee will look to see what colleagues are doing in order to make a decision. This information relates to me professionally because I will be starting my career as an auditor soon and the attitudes and ethical culture of the company and my colleagues will definitely affect how I perform my Job.Reader also discussed how a leader can promote and ethical culture. These ten pieces of advice would definitely help me in a professional setting because at one mint I will be leading a group of people on an audit engagement. The first piece of advice is to walk the walk, which means that the leader n eeds to lead by example. Next, he states that the leader should keep people in the loop. This means that the leader needs to involve the employees and inform them on various changes and adjustments happening in the organization.Reader suggests that the leader should also encourage thoughtful dissent and show the employees that he/she truly cares. Furthermore, Reader states that in order to promote and ethical culture, the leader would not sweep problems under the rug, but should deal with each problem In an ethical manner. In Dalton, the leader should celebrate the successes In the organization and be fair to all employees. Also, the leader should make ethics a priority.Often times In the professional world, leaders behave ethically but do not truly make ethics a priority. Although sometimes difficult, leaders need to make tough the leader should â€Å"get the right people eon the bus and keep them,† which means that the leader should find employees that share the same ethica l values and do whatever is possible to keep them on board. Overall, I think Reader provided some great examples and advice on ethics and ethical leadership.All of the examples and advice he discussed relate to a professional environment and especially auditing. Auditors do not have the best reputation because of unethical behaviors by professionals, like Arthur Andersen, in the past. Often times the auditing profession can really challenge and test an individual's ethical and moral compass. However, Reader's speech reminded me what I need do to make sure I maintain ethical relationships and become an ethical leader in my audit career.

Moral Correctness And Its Effects On Society Essay

Societies have traditionally set up a system of laws that a culture learns to accept as the moral and just norm. Cultures and societies then learn right and wrong from this system of laws and rules and soon accept them as the moral truth. However, some individuals choose to side with innate morals of emotions and of nature, rather than the learned system of moral ‘truths’. These people would believe that there is no such thing as inherent good and evil in the world, as defined by law, that those labels are simply artificial constructs of their society. Right and wrong are so often determined by the people who hold positions of authority: that is the way it has always been so how then can anyone know the ‘truth’ of right and wrong or the ‘truth’ or morality? The world is, in fact, one big moral ‘grey area’; it cannot be carefully categorized into good and bad or good and evil as people would like it to be. Moral correctness cannot be as simple a matter of obeying the laws and rules set up by authority while ignoring one’s emotional and natural code of ethics. This idea of good and evil and of moral correctness is explored within Herman Melville’s novella, Billy Budd, Sailor. Captain Vere, who serves as the authority aboard the ship, Bellipotent, although believing he was upholding the proper morals of the situation at hand, from the view of the laws upon his ship and under the king and country he serves, made the morally wrong decision in sentencing Billy Budd, an ethicallyShow MoreRelated Is Charles Perrault’s Little Red Riding Hood Relevant to the Modern World?1470 Words   |  6 Pagesgroups, recognizing that they would also like a seat on their starship to salvation, have fought for their civil rights and equality through various social reform movements.
