Lead is a naturally occurring metal found in the earth's crust. Lead can be found everywhere, because of human activities such as burning fossil fuels, mining, and manufacturing. Lead is a soft, heavy, toxic metal. Lead is found in many products we use every day, it is even found in toys. It is also in the paint in many houses and in some dirt and dust. Lead Poisoning means having lead in the body in an amount that can cause serious health and development problems. It is much more dangerous for children than adults because it affects kids’ developing brains and nervous systems. The younger the child, the more harm lead can cause. Lead can cause serious health effects: kidney problems, anemia, hearing loss, development delay and growth problems. The only way to know for sure if you have lead poisoning is to have blood test.
People who are most at risk of harmful effects from lead in their body include (Risk Factor, 2010): * Babies and children under 6 years of age. Infants and young children are more likely to be exposed to lead than are older children. They may chew paint chips, and their hands may be contaminated with lead dust. Young children also absorb lead more easily and sustain more harm from it than do adults and older children. * Children living in older homes. Although the use of lead-based paints has been banned since the 1970s, older homes and buildings often retain remnants of this paint. * Children living below the poverty level. Although any child can be exposed to lead, children from low-income families are disproportionately affected, often because they live in older or unrenovated housing. Nonwhite children tend to have higher rates of lead poisoning. * People with lead amalgams in their teeth. Although lead is no longer used to fill cavities in children's teeth, some adults may still have these fillings. *…...

Module One Case

...Module 1 Case 9/5/2012 The Disconnection of Being Connected Martin Carnoy wrote: “Thanks to a communications and software revolution, we are more ‘connected’ than ever before—by cell phone, email, and video conferencing—yet more disconnected than in the past from social interaction.” In the past, any time you needed information or help doing something, you had to walk or ride into town and speak to whoever specialized in what you wanted to know. Face to face discussion was the only way to tell people things or to find things out. It later developed into calling one another, which no longer needed face to face but still required a decent amount of social skills. Now, social networks, the internet, and texting creates a world that many people can tap into for hours without ever seeing another human being. They can update hundreds of people in the split of a second on Facebook and Twitter using a smartphone, which I’ve seen people as young as 8 years old own. Angela Mollard blogged about this issue and stated, “But, recently I’ve felt disconnected, which is absurd because last year I received 13,506 emails, sent 432 tweets and became Facebook ‘friends’ with someone I kissed in 1989. I’m so connected that I go online the second I wake up. I’m linked in, favourited, retweeted, liked” (Mollard, 2012). As Mollard states, I also believe that all of this technology connection has done nothing but pull us in closer to the virtual people while in all reality, pushing the people in......

Module 5 Case Study

...Module 5 Case Study Scott Daniels’ job was to lead a team of people from both the medical instruments company and his own firm to identify and resolve quality-related issues with the EIS and to develop a plan to help prevent quality problems from happening on future projects. According to the case study the first thing Scott’s team did was to research the problem with the EIS. I am underlining this because the first step in any problem solving situation is critical. Also, Scott’s team created a cause-and-effect diagram similar to the one in figure 8-2, they also created pareto chart to help analyze the many complaints the help desk received and documented about the EIS. So I asked myself if there is any reason why they used only the cause-and-effect diagram and the pareto chart among the seven Basic tools of Quality. Did Scott daniels and his team apply the basic problem-solving technique or process. I found out through my researches that there are SEVEN STEP PROBLEM SOLVING TECHNIQUE The History The method was developed by The Quality Management Center in Cambridge, Massachusetts, USA, with its purpose being to find suitable solutions to problems identified. The Principle The method is based upon PDCA (Plan-Do-Check-Act) and SDCA (Standard-Do-Check-Act). It looks for the causes of problems, aimed at improvement. It is process-oriented. The original wording of the method consists of the following steps: Problem – Data – Cause – Solution – Results – Deployment –......

Module 4 Exercise 36

...null hypothesis is that the mean mobility scores for both groups are the same, since the p-value 0.005 < 0.05 the null hypothesis can be rejected. Therefore the mean difficulty with mobility score for both groups must be different. “3. The researchers stated that the participants in the intervention group reported a reduction in mobility difficulty at week 12. Was this result statistically significant, and if so at what probability?” Yes, the result was statistically significant at probability p < 0.001. “4. If the researchers had set the level of significance or α= 0.01, would the results of p = 0.001 still be statistically significant? Provide a rationale for your answer.” Yes, the results will still be statistically significant because 0.001 < 0.01 “5. If F(3, 60) = 4.13, p = 0.04, and α = 0.01, is the result statistically significant? Provide a rationale for your answer. Would the null hypothesis be accepted or rejected?” In this case the result would not be considered statistically significant because 0.04 > 0.01 “6. Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group? Provide a rationale for your answer.” No, ANOVA cannot be used to test proposed relationship or predicted correlations between variables in a single group because ANOVA is a technique that is used to compare the means or averages of more than two groups. You are comparing and contrasting your interpretation with your......

...achievement of the organization’s objectives.3 3 4— S T R A T E G I C C O R P O R A T E S O C I A L R E S P O N S I B I L I T Y Simply put, a firm’s stakeholders include those individuals and groups that have a stake in the firm’s operations. Such a broad view has not always been the norm, however. Over time, as the impact of business on society has grown, the range of stakeholders whose concerns a company needs to address has fluctuated—from the initial view of the corporation as a legal entity that is granted societal permission to exist by charter, to a narrower focus on the rights of owners, to a broader range of constituents (including employees and customers), and back again and at the end of the 20th century, to a disproportionate focus on shareholders. Increasingly, however, companies are again adopting a broader stakeholder outlook, extending their perspective to include constituents such as the communities in which they operate. Today, companies are more likely to recognize the degree of interdependence between the firm and each of these groups, leaving less room to ignore stakeholders’ pressing concerns. Just because an individual or organization meets this definition of an “interested constituent,” however, does not compel a firm (either legally or logically) to comply with every stakeholder demand. Nevertheless, affected parties who are ignored long enough may take action against the firm, such as a product boycott,4 or they may turn to government for......

...Brenda Crain Sept. 14, 2014 Writing Module 2 Exmplification Essay final draft Marriage Versus living together I choose this topic because it is a difficult decision that many of us make in todays world. Statistics say that married people are healthier, happier, live longer, have higher income, less violence and more fulfilled then couples living together. I feel it may be true for some couples but not all. Couples might choose to live together instead of geeting married because one has a huge amount of debt. Marrying them will have collection agencies going after their money. When you are married both incomes are counted when applying for grants, loans and state help. Its somtimes much easier not to marry, rather thann not ge help ones family needs because of combined incomes. I think couples might choose to live together without marriage because of their financial situation. Now in days people can not make ends meet living alone. Some couples live together in case the marriage does not work. They do not have to worry about cost of divorce and all the paper work that is involved. Now in days most of the population live together firs before becoming marry. I know young people age around 18 and 20 are more likely to move in together or start a relationship faster than older adults. This day in time alot of adults are waiting later years to make this commitments. Because of younger age lack of maturity. My...

Research Methods Module 4

...John Adams Research Methods Module 4 Research I am a lover of music and everything that goes with it. I consider myself an early 90’s Sony Walkman baby, a true audiophile at heart. One of my passions in life is to collect headphones and portable media players. Also I need good music to go with all that gear. One of my peeves is the quality of the music I am listening to. Not in the sense of album artist and the songs they sing but the media it’s presented on and the overall quality of the music itself. In the near future I would like to spoil myself with a new media player. The media player comes from a company called Astell & Kern. Astell & Kern are the leaders in portable audio equipment. One of two key features I like most about their players is the ability to play High-Resolution Audio. High-Resolution Audio is in a class of its own when comparing quality to an mp3 file. The second is quality of the DAC chip inside the player. The DAC or Digital Audio Converter turns the digital signal into an analog signal thus creating a more natural sounding tone. One of the more recent releases is their new AK JR model PMP (Portable media player). Two key features of this specific model id thin and light design and an increase output with lowered impedance. As a “portable” device its design and weight is very important to me. I carry these devices with me all day, every day and being too heavy or an eyesore is very important to me. With an increased output and lower......

While by the definition we have seen so far in this course of a project being successful by being completed within the original timeframe and on budget, there are many outcomes that can also be considered a success even if the project busts the initial timeline and has had extra accumulated costs. Cost estimates and project timelines are not an exact science and the Project Manager goes into the project using the best available estimates and must build in flexibility throughout the schedule to ensure if things do go off path that they can steer things back in the right direction. This is true in the high-rise construction case at the center of discussion as well as IT projects that you and I may see take place within our organization. For this......

I honestly feel that if these two stories were switched and put into other places. The readers may be expecting to read something totally different and may be let down when it is time to start reading. 3. Which kind of profile would you most enjoy writ- ing? Or would you rather write something that falls between the two? Explain your choice. I would enjoy writing a profile that falls in between the two. Something that is informative and gives plenty of historic facts, while also telling a good story that will entice and catch the reader’s attention to keep on reading. 4. “Welcome to the Jungle” has more energy and snap partly because it tells a story.

...Module 4 6. In animal cells a cleavage furrow forms during cytokinesis. While in plant cells a cell plate forms in the middle of the cell. The furrow in animal cells is a contractile ring of actin microfilaments associated with molecules of the protein myosin. Action reacts with myosin causing ring to contract. The furrow deepens until parent cell divides into two producing two separate cells with their own nucleus and share of cytosol, organelles, and other subcellular structures. In plant cells vesicles from the Golgi apparatus move along the microtubules to the middle of the cell, where they coalesce, producing a cell plate. The plate enlarges until its surrounding membrane fuses with the plasma membrane along the perimeter of the cell. Two daughter cells result, each with its own plasma membrane. Meanwhile, a new cell wall arising from the contents of the cell plate has formed between the daughter cells. 7. Eukaryotic cells have a true nucleus, bound by a double membrane Prokaryotic cells have no nucleus. Eukaryotic DNA is linear; prokaryotic DNA is circular (it has no ends). Eukaryotes go through every phase of Mitosis including prophase, metaphase, anaphase, and telophase. Prokaryotic cell simply divides by cytokinesis after DNA replication which is known as binary fission. 8. Checkpoints make sure that the eukaryotic cell completes each phase with no problems. Without checkpoints it may affect cell growth which is very important. 9. The Hershey-Chase......

Whether we are talking about marketing information, cost projections, accounting results, or internal quality reports, every company depends on knowledge to support its planning, decision-making, and control. So how does knowledge fit into the picture? The emergence of the field called knowledge management has highlighted some key propositions in the last 10 years or so. All organizations are storehouses of knowledge that operate in information-rich environments made up of people and things both inside and outside the organization itself Organizations organize, interpret, and evaluate this information to solve organizational problems Knowledge is the primary mechanism for processing and utilizing information People's brains are the key knowledge resource of any organization Codified knowledge stored in books, audio, videotapes, and computer systems can be an important knowledge resource as well There are organizational processes and strategies for IT management and management in general.

Mgt599 Module 1 Case

...Trident University Module 1 CASE Assignment MGT599: Strategic Management Process/Vision, Mission, Goals and Objectives Dr. Nanette Metz June 19, 2016 Executive Summary Coca Cola Company has executed the most successful beverage strategy of the past 50 years. Its strategic communications, however, fall short of the success of its underlying strategy. Coca Cola advertises a formal mission statement that does little to communicate its strategy to its stakeholders, and should therefore reshape a more specific formal mission statement. Its vision statement is hidden deep within its website, and also falls short of guiding the company's future. While the vision statement more closely aligns with the company strategy, it should also be reshaped in order to provide a more specific tract for future growth and goals. Introduction Coca Cola Company is the most successful beverage enterprise in the United States-it is the largest (as measured by customer volume), among the oldest (125 years in business), and most profitable (with 59 consecutive years of dividend growth), (Coca Cola, 2016). Coca Cola operates under a winning strategy- and when a strategy is working, it should be largely left alone. All that remains is synchronizing all the elements of an organization in order to execute such a strategy with efficiency. The most fundamental purpose of a strategy, after all, is to "inform each of the many thousands of things that get done in an organization every day, and......

...Research Methods for the Health Sciences – Module 1: Case The Research Question, Literature Review, and Research In any research plan devising the research question is a critical step in the research process. It helps in determining what, where, when and how data will be collected. A properly developed question can help focus ideas and ensure the collection of appropriate data. In this case study I will discuss how descriptive research questions differ from questions of relationship and questions of comparison. Then I will discuss how a researcher should determine if prior research exists on the intended topic. I will also discuss what factors should be used to gauge the quality of previous research as well as the importance of the assessment. Finally I will discuss if the formulation of a research question should precede or follow consultation with scholarly literature Descriptive, Relationship, and Comparison Research Questions. There is a distinct difference between descriptive and relationship research questions. According to Newton, Bower, and William (2004), the descriptive research describes data and characteristics of information being studied by answering question of who, what, when, where, and why. It contains factual information but does not determine the cause or create a relationship between the information. In contrast the relationship question uses the......
