Lead and The Environment
Some materials are so commonplace that we take them for granted. One of those materials is a grayish metal that has been with us for thousands of years.
That metal is lead, still one of the world's most useful substances, and one that never ceases to find a role in human society.
Lead has the atomic symbol of Pb (for plumbum, lead in Latin). The atomic number for lead is 82 and the atomic mass is 207.19 AMU. It melts at about 327.502 oC and boils at 1740 oC. Lead is a heavy, ductile, soft, gray solid. It is soluble in nitric acid and insoluble in water. It is found in North,
Central and South America, Australia, Africa and Europe. In modern times, lead has found a wide range of uses, and world demand for lead and its products has steadily increased. Lead's usefulness stems from the metal's many desirable properties: softness, high density, low melting point, ability to block radiation, resistance to corrosion, readiness to form alloys and chemical compounds, and ease of recycling. Its versatility, as well as its physical and chemical properties, accounted for its extensive use. Lead can be rolled into sheets which can be made into rods and pipes. It can also be molded into containers and mixed with other metallic elements.
Lead was used in ancient times for making coinage, art objects and water pipes. One of the first known toxic substances, lead was used by the Romans for lining aqueducts and in glazes on containers used for food and wine storage; and it is suspected to have resulted in widespread lead poisoning. Members of the famous Franklin Expedition to the Northwest Passage in the mid-1840s met a similar fate, being poisoned from lead in solder, widely used at the time to seal tins used to store foods. Until recently, one of the most significant uses was an anti-knock additive in gasoline. In the 1970s and 1980s, steps were taken to reduce the use of leaded gas. By 1990, these actions had virtually eliminated the use of lead in gasoline. Lead is also one of the best and earliest examples of recycling about 55 percent of the lead used in Canada comes from recycled material. One particular category of toxic tort is injury caused by exposure to lead-based paint. The hazards of lead-based paint have been known since the early 1900s, when the use of lead in the manufacture of paint was banned in
Australia. The lead mining and lead pigment industries in the United States were able, however, to forestall the banning the use of lead in the manufacture of
lead and mercury. Still others were more based in superstition such as wearing amulets made of
The news media rejects the fact that they are biased. They claim that they are the “middle of the road,” and are neutral on the stories that they cover. Publishers also claim that they are the watchdog for the political system, and they make sure that the system is free of any corruption, or wrongdoing. Th...
... prejudice, bias, and in a general manner that imposes their views onto an audience. Yet, it is an entirely different story when stories are written in a specific manner for other reasons than to impose individual politics. The reasons mentioned throughout this paper are just some of the many ways in why a journalist might account for the story’s bias, and why news organizations thrive and depend upon such methods. Also, one of the most important key concepts to keep in mind when discussing bias in the media is that much has changed with new technologies. Just for example, budgets have been more restricting, consumer expectations have changed, and the audience expects stories to be shorter and more visual. With this being said, there are not always internal pressures, but there are physical and external restrictions and limitations that encourage bias as well.
Commitments include a lifetime of learning, following standards, participating in memberships of professional organizations, and ensuring that nursing care is being provided at the highest quality levels (Finkelman & Kenner, 2016). The American Nurses Association (ANA) and its members developed the Nursing: Scope and Standards of Practice (ANA, 2010a). The ANA defines The Standards of Professional Nursing Practice as “authoritative statements of duties that all registered nurses, regardless of role, population, or specialty, are expected to perform competently” (ANA, 2010a). These standards are important to nursing and the delivery of healthcare as they maintain safe, clinically capable and competent nursing practice. Equally, they are imperative to our nursing profession as they guide and promote clinical practices as well as influence the quality of those practices. Professional standards are utilized to provide structure for developing clinically competent checklists and proficiency evaluations (Davis, 2014). Furthermore, professional standards of practice aid in the development of safe practices by defining a scope of practice. The definition of “who, what, where, when, why, and how” (Finkelman & Kenner, 2016) that a scope of practice defines, helps determine safe nursing
To understand if what you are tuning into or what you are reading is bias to something in particular then you must understand all the different types of biases that occur in the media. The biases in media
Today, many types of media bias are used as a strategy by reporters and politicians to sway the public into agreeing with their views. They have gone far enough to make the U.S. public recognize the bias and distrust the Media. First off, there is bias by omission. This consists of leaving out one side of an article to make their views seem more credible. For example, a republican may focus on facts that support conservative beliefs, and leave out liberal supporting facts. Next, there is bias by selection of sources. In this bias, the selected source will support the views of the selector. For instance, a republican would choose a conservative “expert” to report. Another bias is that of story selection. For this bias, an individual would highlight and share stories supporting their views and ignore the stories against their views.
Nurses are always doing new things like procedures, answering questions asked by family members, facing challenges in their day-to-day routine and often questioning the legitimacy the of their actions. Most guidelines are found in the policy and procedure handbook of the nurses’ hiring facility. These actions are usually within the scope of the Nurse Practice Act (NPA) and Board of Nursing (BON). The State Board of Nursing is a government agency and responsible for regulating nursing practice and defining the responsibilities of the nurse and the scope of nursing practice, which are qualifications that the nurse has for practice. "The scope of practice statement describes the "who," "what," "where," "when," "why," and "how" of nursing practice. Each of these questions must be answered to provide a complete picture of the dynamic and complex practice of nursing and its evolving boundaries and membership. The profession of nursing has one scope of practice that encompasses the full range of nursing practice pertinent to general and specialty practice. The depth and breadth in which individual registered nurse
This type of bias means to leave out or omit one side of an article that the media owners disagree with or does not fulfill their interests.
Do you believe the argument was good enough to support the conclusion? Would you be able to use this article if you had to do a research paper on media bias? The article was not good enough to support its conclusion because it talks a lot about different subject and does not focus just on one subject it talks about all not giving enough information about the main topic being read. I would not be able to use this in a research paper because in my opinion it’s not good enough to use.
I'm going to analyze two different articles based on the same topic to distinguish the different bias within media and compare the bias within the two. The two articles discuss the U.S. Senate voting on the Keystone XL Pipeline. The Keystone XL Pipeline is project
College can be a fun and exciting part of your life. But fun and excitement usually cost money. You have to pay for movie tickets, the late runs to Taco Bell, snacks, soda, and all the extras you want to decorate your new place with. Money is hard to come by in college. You spend most of your day in classes and if your parents have decided to not give you lots of money, you spend most nights working part-time. Working while attending school is not fun at all. It leaves you with little time to study or get homework done. And the little time you have is usually in the early hours of the morning, depending on how late you stay up. But you have to work in order to buy the things you want and to be able to eat out instead of eating the dorm food (which is surprising just as bad as high school lunch).
Lead is a lustrous, silvery metal that tarnishes in the presence of air and becomes a dull bluish gray. Soft and flexible, it has a low melting point (327 °C). Its chemical symbol, Pb, is from plumbum, the Latin word for waterworks, because of lead's extensive use in ancient water pipes. Itsatomic number is 82; its atomic weight is 207.19.
Being biased is having a preference for one thing, usually in an unfair way. This is when someone has an one-sided opinion and does not have any room for considering alternative viewpoints. Views that are biased may be directed towards an individual, religion, political party, social class, nation, species, or any other distinct group. Biased acts may be expressed in many forms, but the most common is in the mass media. The media use this based on the perception of the producer or reporter within the media in the events that are being personally covered. When media bias is present in a news source, it is using a prejudiced approach and is leading to leaving out important sections of the whole truth. The source chooses to leave out these facts just because it does not support the message that corresponds to

Nurse practitioners (NP) are healthcare providers that are licensed and practice in an arrays of healthcare locales. According to the Association of Nurse Practitioners (2015), nurse practitioners can practice as autonomous practitioners in acute, ambulatory, and long-term facilities as either a primary providers or specialty providers. Each nurse practitioners’ state board of nursing plays a considerable role in their scope of practice with focal point on the community at large fortification and healthcare safety. Furthermore, the ability of the nurse practitioners to practice to fullest extent of their knowledge are structured, or governed and regulated by state law and the individual’s state Board of Nursing scope of practice (Xue, Ye,
