A Brief Look at Breast Cancer Essay - 1736 Words

BREAST CANCER Introduction/Background Cancer is characterized by unregulated/uncontrolled growth and spread of abnormal cells. The etiological factors of Cancer include both external factors (tobacco, infectious organisms, chemicals, and radiation) and inherent factors (inherited mutations, hormones, immune conditions, and mutations that occur from metabolism). The etiological factors may act together or in sequence to trigger the development of cancer. It may take several years for the manifestation of the disease to be obvious after the initial trigger. CDC: Female Breast Cancer Incidence Rates by State, 2010 Incidence/Mortality Breast cancer is the most common non-cutaneous malignancy, it accounts for one third of all†¦show more content†¦The incidence rates of in situ breast cancer increased by 2.8% every year between 2005 and 2009. It is estimated that 40,030 deaths from breast cancer (39,620 women, 410 men) are will occur in 2013. Breast cancer is second only to lung cancer as the leading cause of cancer deaths in women. Breast cancer death rates have been decreasing steadily since 1989, rates decreased by 3.0% per year in women younger than 50 and by 2.0% per year in women 50 and older between 2005 and 2009. This decline is attributed to prevention, early detection, improved healthcare services and reduced use of MHT. CDC: Female Breast Cancer Death Rates by State, 2010 CDC: Female Breast Cancer Death Rates by Race and Ethnicity, U.S., 1999–2010 Signs and symptoms There are no symptoms at the early stages of breast cancer which makes early detection even more difficult. When tumors become large there is an obvious breast mass which is mostly not painful. Symptoms of breast cancer include breast thickening, skin irritation, tenderness, swelling, breast scales, distortion, redness tenderness, nipple retraction and ulceration, There may also be abnormal discharge. Risk factors for breast cancer Age: Breast cancer incidence increases with age, it doubles about every 10 years until the menopause, after which the rate of increase slows dramatically.

Systems Outsourcing Relationship Factors †Free Samples to Students

Question: Discuss about the Systems Outsourcing Relationship Factors. Answer: Introduction: Offshoring is the mechanism most information technology related firms have been capitalizing on not only to increase profits but also to expand their business. It has become a norm for the information system (IS) company's activities and functioning (King, 2008). Much of the success of the successes of this strategy can be attributed to relations in the products and functioning if the offshoring sites. There has been understanding that in offshoring and outsourcing to be successful there had to be stable interdependence and continued the exchange of information. However, it worth noting that some companies have reaped and achieved a lot in offshoring without interlinking their offshore companies. The interdependence between the companies declines with time as their activities continue to be distinct. An example is the two-phase offshoring exhibited by an Irish site for the Pennysoft and Semicon global companies of the U.S. (Conchuir, Holmstrom, Agerfalk, Fitzgerald, 2008). Competiti on is taking center stage in the business, and this will progressively lead to an advance from two-stage offshore sourcing to multistage offshoring. Based on the study by Conchuir, Holmstrom, Agerfalk, Fitzgerald (2008) I have realized there are different designs can adopt offshoring. For example, the Semicon Company fends off any interdependence in offshore sourcing at early stages of their projects as opposed to Pennysoft that advocates for a relationship of its activities to the finishing line. My understanding has been, for the offshore sites to continue running they will have to depend on their mother company of a bridge site. In Semicon, the Irish and Indian sites are independent of the U.S. site in conducting their day-to-day activities. Reducing cross-site interdependence consequently, reduces the communication and coordination costs of the cross-sites. It's only in unique projects that require the skills of the other site relationship can exist. I have been holding to the idea that communication at all levels should be emphasized between the sites. The Semicon company communication between the team is limited to a certain degree, that is, at managerial level. Their engineers have no communication with others, which is an effort to minimize overhead communications. Coordination cross-sites is another aspect of importance for the running of sites that are in different locations. The Irish places in both companies are bridging between the U.S. and the Indian sites to enhance the smooth running. The three locations, in this case, carry out different activities that contribute to the accomplishment of various projects. I have a firm believe that geographical separation between the gaps has to be bridged to ensure successes in the business. However, the in Semicon company, there is little coordination between the U.S, Irish and Indian sites since little communication is exercised between them. Limited communication thwarts coordination. Surprisingly, the Semicon Company is managing its activities well with little focus on cooperation. I have an understanding that a hierarchal organization enhances the proper execution of duties (Goles Chin, 2005). For example, the U.S site being the main company should delegate responsibilities to the Irish site which will then transfer them to the Indian site. Like the Pennysoft activities are chiefly run by the U.S site, to the Irish and then appointed to the Indian site. At Semicon, this is different since every site operates as an independent entity and does not adopt a hierarchal form of organization. Even without following such organization Semicon manages to run its activities. References Goles,T., Chin,W.W. (2005).

Tartuffe Summary 2 Essays - Film, Tartuffe, Vocal Music,

Tartuffe Summary 2 Molire was born Jean-Baptiste Poquelin Molire was born in 1622 in Paris, France and died there in 1673 (Molire, p.1). He spent his life writing plays, acting, and managing the stage, according to Encyclopedia Britannica and is known as the greatest of all writers of French comedy (p. 1). Recently, I was able to see one of his best known plays of all times on campus at Oklahoma Baptist University in Shawnee, Oklahoma. According to the program given to me at the theatre that evening, the play was transcribed into the English language by a man by the name of Richard Wilbur (Molires Tartuffe). Tartuffe (also sometimes referred to as The Imposter) is set in the realm of seventeenth-century Parisian high society during the reign of King Louis XIV (Tartuffe, p.1). This paper is a summary of my experience at the theatre. The cast of the play at Oklahoma Baptist University was performed by current students and previous students and consisted of thirteen different people in acting roles. In addition, there were eight members of the artistic staff and twelve members of the production staff who helped to make the production a huge success. The director for this production was Dr. Jeffrey Wells, PhD who is an Associate Professor of Performance and the Director of OBU Theatre and has been the director for greater than twenty different full-length plays at the college level (Molires Tartuffe). The characters in the play were few but, they were extremely powerful. There was Tartuffe, the villain who deceived everyone into thinking he was a devout Christian focused only on the things of the Lord. In reality, he was a hypocrite who took advantage of all of the other characters as used them as a means to his own end. Then, there was the father, who believed everything that Tartuffe said and allowed him to move into his home and entrusted him with his most valuable possessions. Ironically, Tartuffe had been making secret advances to the fathers wife all along. There were also male and female siblings present in the play who tried to tell their father that this man was not to be trusted. The son was especially vocal about it. Another character in the play was the mother of the Orgon, the father. She too had fallen totally for everything that Tartuffe had told them. In addition, there was Valre, who was to marry the daughter, Mariane. One of the calmest and most endearing charact ers was the brother-in-law who tried to keep the rest of the family calm and acting with reason. One of the funniest of characters was the daughters maid, Dorine. Additionally, there were a few of other characters M. Loyal, the process server who brought them eviction papers, the two maids of the grandmother, and the kings man who gave them the greatest news of all. When the play began, the grandmother was singing the praises of the houseguest Tartuffe and encouraging her family members to become more like him because he was above reproach. She rails at them when the house members try to tell her differently concerning Tartuffe. She refuses to believe and leaves the castle. Then, the members of the castle discussed Tartuffe and how Orgon was being deceived. They came up with a plan to confront him about it. Soon, the father enters, going about his business. As various members try to talk to him, he can think of nothing but Tartuffe. It was during this scene that the father told his daughter that he would like for her to marry Tartuffe instead of her fianc. Mariane was extremely distraught by this; however, she did not have the guts to speak up to her father about it. Before long, Orgon takes his leave and the fianc comes barreling in because he has heard the news of his broken engagement with the daughter of Orgon. Dorine, having overheard all t hat had surpassed, deemed to join with the young couple and started to formulate a plan to expose the hypocrisy of Tartuffe. The next scene, found the wife in the dining room and Tartuffe coming into the room. At that time, Tartuffe begins to talk about his love for

Five Ways to Write Faster

Five Ways to Write Faster Five Ways to Write Faster Five Ways to Write Faster By Ali Hale Whether you need to clear a backlog of emails, write an important document at work, finish a short story, or do your homework, spending hours staring at a blank screen and struggling to come up with words won’t help. If you know you could get twice as much done if only you could write faster, try some of the following methods. Don’t worry about the quality of your first draft Whether you’re writing fiction or non-fiction, many experts recommend just getting the first draft done before starting to edit. That means keeping the momentum going as you write, rather than going back to change words or delete sentences. If you’re a perfectionist and write slowly because you worry about getting every little detail right the first time round, giving yourself the freedom to produce a â€Å"rubbish first draft† can triple your writing speed. Once you’re done, go back and edit: often, you’ll be surprised that your first draft really isn’t too bad! In his book Do It Tomorrow (which I strongly recommend for anyone who struggles to manage their time and attention), Mark Forster recommends writing a series of quick drafts: When I first learnt the techniqute of writing in a series of rapid drafts, my first draft would usually consist of nothing more than a few words jotted down. My second draft would add a bit more and I would go on revising it until I had it in the form I wanted. There are two great advantages to doing it this way. First of all it gets rid of the perfectionist feeling that it has to be got right first time. If I think a sentence is a bit clumsy, what does it matter? There’ll be another draft along in a moment. The second advantage is that engaging with the material in this way allows new thoughts and insights to appear. Outline the piece before starting With bigger projects, it’s easy to get stuck because you’ve come to a standstill or gone off on a tangent. Jot down some notes before you begin: that might be subheadings for a blog post or article, paragraphs for an essay, or plot points for a short story. Type these onto your computer screen – you’ll no longer be staring at a blank document, and seeing the next subheading or paragraph point ahead will help keep you on track. Set a timer for ten minutes and write non-stop until it goes off Have you noticed how much faster you write when you need to finish something before a set time (perhaps lunch, or an essay deadline)? It’s amazing how much your brain can focus when you’ve only got a few minutes. Mark Forster calls this the â€Å"end effect† – speeding up at the end of a piece of work – and recommends using a timer to produce it consistently. Challenge yourself to see how much you can produce in ten minutes. Do your research and preparation separately from the writing Something that can really slow things down is stopping to look up a fact, find a quote, or check a figure. When you write the outline for your piece (see #2), you should have a good idea of what references you’ll need to make. Look these up before you start writing, and have them all to hand. Alternatively, if the process of writing sparks off ideas of websites, books or people you want to refer to, don’t stop to find them part-way through writing the piece. Leave a note in the text to remind yourself of what you want to include; you might want to highlight this in some way so you don’t forget to go back and put it in! For example, in the first draft of this article, I wrote [Quote from Mark Forster on drafting process] and looked it up when I revised the first draft. The same applies if you’re unsure of how to spell a word, or if you can’t quite think of the right phrase: highlight it in some way, and come back to it once the first draft is complete. Turn off distractions (instant messenger, Twitter, email.) If you’re constantly interrupted by friends wanting to chat on instant messenger, by incoming emails, by new posts coming through to your RSS reader – turn everything off. I can write at least twice as fast – and often even faster – without any distractions. You might think it only takes a few seconds to read each message, but every time you turn your attention away from what you’re writing, you lose momentum. I’m great at procrastinating when I should be writing and so I write most of my blog posts first thing in the morning, before I even connect my computer to the internet. This also helps with #4 – I’m not tempted to stop and search for some missing piece of information on Google every few minutes. Have you got any great tips on speeding up your writing? Can you dash off an essay in an hour, or race through your inbox with ease? Let us know what tips and tricks you’ve discovered – or, alternatively, if you’re a slow writer, tell us where you think you’re going wrong! Want to improve your English in five minutes a day?

Snowflake Chemistry - Common Questions

Snowflake Chemistry - Common Questions Have you ever looked at a snowflake and wondered how it formed or why it looks different from other snow you might have seen? Snowflakes are a particular form of water ice. Snowflakes form in clouds, which consist of water vapor. When the temperature is 32 ° F (0 ° C) or colder, water changes from its liquid form into ice. Several factors affect snowflake formation. Temperature, air currents, and humidity all influence shape and size. Dirt and dust particles can get mixed up in the water and affect crystal weight and durability. The dirt particles make the snowflake heavier  and can cause cracks and breaks in the crystal and make it easier to melt. Snowflake formation is a dynamic process. A snowflake may encounter many different environmental conditions, sometimes melting it, sometimes causing growth, always changing its structure. Key Takeaways: Snowflake Questions Snowflakes are water crystals that fall as precipitation when its cold outside. However, sometimes snow falls when its slightly above the freezing point of water and other times freezing rain falls when the temperature is below freezing.Snowflakes come in a variety of shapes. The shape depends on the temperature.Two snowflakes can look identical to the naked eye, but they will be different on the molecular level.Snow looks white because the flakes scatter light. In dim light, snow appears pale blue, which is the color of a large volume of water. What Are Common Snowflake Shapes? Generally, six-sided hexagonal crystals are shaped in high clouds; needles or flat six-sided crystals are shaped in middle height clouds, and a wide variety of six-sided shapes are formed in low clouds. Colder temperatures produce snowflakes with sharper tips on the sides of the crystals and may lead to branching of the snowflake arms (dendrites). Snowflakes that grow under warmer conditions grow more slowly, resulting in smoother, less intricate shapes. 32-25 ° F - Thin hexagonal plates25-21 ° F - Needles21-14 ° F - Hollow columns14-10 ° F - Sector plates (hexagons with indentations)10-3 ° F - Dendrites (lacy hexagonal shapes) The shape of a snowflake depends on the temperature at which it formed. 221A / Getty Images Why Are Snowflakes Symmetrical (Same on All Sides)? First, not all snowflakes are the same on all sides. Uneven temperatures, presence of dirt, and other factors may cause a snowflake to be lop-sided. Yet it is true that many snowflakes are symmetrical and intricate. This is because a snowflakes shape reflects the internal order of the water molecules. Water molecules in the solid state, such as in ice and snow, form weak bonds (called hydrogen bonds) with one another. These ordered arrangements result in the symmetrical, hexagonal shape of the snowflake. During crystallization, the water molecules align themselves to maximize attractive forces and minimize repulsive forces. Consequently, water molecules arrange themselves in predetermined spaces and in a specific arrangement. Water molecules simply arrange themselves to fit the spaces and maintain symmetry. Is It True that No Two Snowflakes Are Identical? Yes and no. No two snowflakes are exactly identical, down to the precise number of water molecules, spin of electrons, isotope abundance of hydrogen and oxygen, etc. On the other hand, it is possible for two snowflakes to look exactly alike and any given snowflake probably has had a good match at some point in history. Since so many factors affect the structure of a snowflake and since a snowflakes structure is constantly changing in response to environmental conditions, it is improbable that anyone would see two identical snowflakes. If Water and Ice Are Clear, then Why Does Snow Look White? The short answer is that snowflakes have so many light-reflecting surfaces they scatter the light into all of its colors, so snow appears white. The longer answer has to do with the way the human eye perceives color. Even though the light source might not be truly white light (e.g., sunlight, fluorescent, and incandescent all have a particular color), the human brain compensates for a light source. Thus, even though sunlight is yellow and scattered light from snow is yellow, the brain sees snow as white because the whole picture received by the brain has a yellow tint that is automatically subtracted.

Exit strategy in monetary economics Essay Example | Topics and Well Written Essays - 750 words

Exit strategy in monetary economics - Essay Example It emphasizes on the significance of the models in determining the uncertain future expectations by incorporating the current macroeconomic outlook. Primarily, the general equilibrium of the model presents the connection between the agents’ behavior and policy action (25). Similarly, the comprehensive specification of the stochastic shocks contributes to the economic fluctuations that facilitate the identification of the transmission of the shocks to the economy (23). The monetary policymakers employ the dynamic stochastic general equilibrium models in conjunction with other statistical tools to determine policies quantitatively. The main characteristic of the DSGE models is the generality in nature. The implication of the general nature of the DSGE is evident in prices and interest rates. In effect, the price and interest rate tend to adjust to the point where the supply and demand in a given market become equal. For instance, the demand of services equals the supply of the same. Similarly, the incorporation of the random components in the model is critically significant in expounding on the cyclical patterns of the economy. The common behaviors in the economy encompass shocks that affect the patterns of financial markets and adjustments in the economic production (28). In turn, the shocks influence the efficiency of production. The dynamic stochastic general equilibrium models estimate the shocks, as well as the proportions adjustments in economic activity that emanate from certain market disturbances. For instance, the models can be crucial in assisting the economists to decipher the nature of the shocks during economic downturns. Notably, the DSGE models can offer answers to the recent economic recession by determining whether the economic downturn was due to financial or fiscal shocks. The supply and demand blocks, as well as the rate, comprise the structure of DSGE models. The central banks employ the models to
