The House and Senate essays

The House and Senate essays In 1781 at the Constitutional Convention was where it all began. Everything was put on the table for the hope of a new and improved well working government. Since there was already a preview (The Articles of Confederation) of what our government was shaping out to be 55 men strived, persuaded, compromised and worked diligently for a strong constitution. Thanks to the Great compromise out came the solution. There was to be three branches of national government: Legislative, Executive and Judicial. In todays constitution Article 1 is discussing the first of the three branches, the Legislative Branch. This is in fact the longest article of the Constitution; there is much to cover. The Legislative Branch consists of the Congress, the Senate and The House of Representatives. There are many duties and details to this powerful branch but its main and major job is to make our countries laws. The lawmaking process is quite a lengthy process. The law (bill) must be purposed to either house and then is sent to a committee. From there it is either re-written as a recommend passage or ignored. After this it is read over and if the bill has made it this far then the whole house votes on the bill. If it passes favorably then the second house votes on it after this the bill goes to the president. The president has some choices he can pass the law by signing it, reject it or veto it. Though the House and the Senate play a large role in the lawmaking process they have different duties. I n the Senate their duties consist of: passing bills, approving treaties by the President, jury of impeachment process and they also approve the selection of certain federal officers. The duties of the house are, pass bills to the Senate and President, sole power of impeachment process and they also have the important duty of selecting the president if there is no majority vote. All of these processes and details make our laws and leg ...

Most of what Miebach does to perfect her art is extremely interesting. However, the most fascinating fact is when she utilizes vertical and horizontal elements of baskets and carefully constructing three-dimensional frameworks of weather basing on real-life weather patterns. It is also interesting that the natural phenomenon called storms can be transformed into musical compositions and sculptures. From Nathalie’s work, I can define art as an innovation and development of basic principles of nature into gorgeous forms suitable for human use. It resides in the quality of doing, a process that needs creativity and understanding of different `occurrences around

New Product Questionnaire Essay Example for Free

New Product Questionnaire Essay As a woman you are created with a special gift, it’s like little extra ingredients that all women have within them. The poem â€Å"Phenomenal Woman† by Maya Angelou, she speaks about the elegance of a woman, her inner being the way she glow without saying a word Maya expressed how men are amazed by her presence â€Å"men themselves have wondered what they see in me† (line 31-32). It’s hard to put your finger on it all women were born with the power. In the poem â€Å"Still I rise† by Maya Angelou she described the struggles of life trials and tribulations you face in society and the way people may judge you. As if she was writing about a woman â€Å"does my sassiness upset you? †She also wrote in another stanza â€Å"does my sexiness upset you? †She used this comparison to show she is a sexy woman who demands respect. Maya’s attitude in this poem is portraying a confident black African American woman. She is really laughing at men challenging them. They cannot stop her from rising above all expectation. This poem gives you not only inspiration encouragement to be fearless; to the end of it all you must believe you still rise above it all. The title gives a sense of entity and power. This masterpiece the poem â€Å"phenomenal woman† has also empowered women to get more in touch with their inner beauty. Maya describes in great detail the mystery of women and the behavior of men and their reaction. It shows women to not only love your-self but to embrace every aspect of your mind, body and soul. Maya show that sexuality isn’t only related to outer beauty, or by the way you dress it more about how you feel within your own skin . she shows you instead of hating your body love it from the crown of your head to the sole of your feet. In society today women enhances their body by doing plastic surgery to feel accepted. She feels inferior clearly stating that every part of a woman is beauty. In comparisons to â€Å"Phenomenal Woman† and â€Å"Still I Rise† both poems Maya speaks about not bowing to the â€Å"oppressor†. You can feel her compassion in every word in Phenomenal Woman â€Å"now you understand why my head’s not bowed† (lines 47). Still I Rise forth stanza â€Å"with head bowed and eyes lowered? †Within these lines she stresses that she will not conform to what society made her out to be, that she will soar above and beyond everyone expectations. The little gives a sense of entity and power. In conclusion these two poems have few similarities; Maya characterized the strength of an African American woman. By using powerful words she described the emotional aspect of inner beauty, standing proud professing no one will ever bring her down not by the color of her skin nor the fact of being a woman that there’s more within.

Alarm Fatigue and its Effects on Quality Patient Care Essay example --

Hospitalized patients are often hooked up to monitoring devices such as heart monitors, which monitor the electric activity of the heart, or connected to a physiological monitor so their vital signs are constantly being measured. These monitors are intended to continuously assess the patients’ status, and alarm if the patients’ status drops below what is considered normal. The increased use of monitoring devices has created a new phenomenon known as alarm fatigue. According to the ECRI institute (2011), â€Å"alarm fatigue occurs when the sheer number of alarms overwhelms staff and they become desensitized to the alarms resulting in delayed alarm response and missed alarms-often resulting in patient harm or even death.† Alarm fatigue has become a major problem within the nursing community and has already had a negative impact on patient safety. Due to the adverse effects alarm fatigue is having on quality patient care, there has been a call to action to find s olutions that may deter alarm fatigue. Evidence-based practices involving quality improvement initiatives have been put into effect. The problem has also gained national attention from such institutions as the Food and Drug Administration (FDA) and The Joint Commission (TJC). Relevance to the Profession of Nursing According to the Registered Nurse (RN) Scope of Practice Position Statement, â€Å"the RN is responsible for providing safe, compassionate, and comprehensive nursing care to patients and their families with complex healthcare needs† (Texas Board of Nursing, 2011). Nurses often care for five to six patients at one time; therefore, in order to provide the best quality care, patients are often connected to monitoring devices such as, physiological monitors, venti... ...ientSafetyOrganization/Documents/PSO_Monthly_ Brief/ECRI%20Institute%20PSO%20Monthly%20Brief%20v1.pdf Graham, C.

Waking up is never the highlight of my day, but never the less tat time of day always comes every morning. This morning was no different. Black and Yellow blared through my phone at 0630 like I asked it to, but it just seemed too early. I fought to truly wake up right away, then I laughed at myself for thinking that thought. Seeing how being out of the house was the goal that morning, I decided to get out of bed at 0700. When I woke up that morning it was not my goal to nag my husband to death, but lucky him it happened. He decided to make chili in the dining room. I am not sure why he did it, and when I asked him he just said that he wanted to. I don’t think the dining room is a place to cook, but he thought so this morning. The roles that I play on any given day range from all sorts of things. When I wake up I am always a mom and a wife. I am here for my husband to help him and guide him when things don’t happen the way that I want. Being a mom is the best thing, and knowing that when I wake up I get both of those roles is why I get up in the morning. The hardest part that I have in these roles is being the person that I want to be. I know that I can do the best that I can and that is how things should be, but I know and feel like I can be better and I want to be that person. Another role that I most recently started playing was cashier at the commissary. That one is a tough one. I need to be able to hold my tongue when need be, but be able to speak my mind occasionally.
