Lab report calibration of volumetric flask Essay Example

Lab report calibration of volumetric flask Essay Example Lab report calibration of volumetric flask Paper Lab report calibration of volumetric flask Paper The accuracy of the measurement the volumes is the degree of closeness of measurements of a quantitys actual volumes while the precision of the volumes is the degree to which repeated agreements under unchanged conditions show the same results. Each of volumetric glassware is marked with its total volume, the notation of AD for to deliver and ETC for to contain and also with the temperature at which the calibration applies. For greatest accuracy, volumetric glassware should be calibrated to measure the volume that is actually contained in or delivered by a particular piece of glassware. The calibration is done by measuring the mass of water contained in or delivered by the glassware. The density of water at a particular temperature is used to convert mass into volume. Pipettes and burettes are calibrated to deliver specific volumes whereas, volumetric flasks are calibrated to contain basis. MATERIAL AND PROCEDURE The materials used in the experiment were:- 10 ml volumetric pipette 25 ml volumetric pipette 100 ml volumetric flask 50 ml measuring cylinder Distilled water Plastic dropper 100 ml beaker 250 ml beaker The procedure 1. Calibration of a volumetric pipette ( 10 ml and 25 ml ) a) An empty ml beaker was weighed to the nearest milliard using electronic weigh balance. B) The ml pipette was filled to the mark with distilled water. C) The water was drained by gravity (remove pipette bulb or pump) into the beaker and caps the bottle to prevent evaporation. D) The bottle was weighed again to find the mass of water delivered from the pipette. E) Then used the following equation to convert mass to volume. F) The above procedure was performed on each of the pipette. G) The experiment was repeated for 2 times. The calibration was done by measuring the mass of water contained in or delivered by the glassware. The density of water at a particular temperature which is measured is used to convert mass into volume. Pipettes is calibrated to deliver specific lumen whereas volumetric flasks are calibrated on a contain basis. BRIEF THEORY: In this experiment, we were exposed to a variety of important concepts related to quantitative experimentation, including the proper use of measuring cylinder, volumetric glassware, analytical balances and statistics. We calibrated a volumetric pipette that was where experimentally determined what volume a pipette or flask really delivers. We also calibrated a beaker and 50 ml burette. A table was constructed according to the result. In this experiment, accuracy and precision is important. The brief theory of calibration of glassware is accuracy and precision. Accuracy is the degree of closeness of measurements of a quantitys actual volumes while the precision of the volumes is the degree to which repeated measurements under unchanged conditions show the same results. For the accuracy and precision of the measurement, scientists need to calibrate their volumetric glassware periodically. Calibration of Volumetric Glassware experiment is designed to help participants to learn both theories and practical skills to effectively calibrate and verify their volumetric glassware. The mass of water, container and temperature is measured and recorded. From the data recorded, we can observe that all the experiment results are not in accurate and stable. For the Mimi pipette experiment, the result is increase from Trial 1 to Trial 2 but decrease from Trial 2 to Trial 3. Then for the ml pipette experiment, the result is decrease from Trial 1 to Trial 2 but from Trial 2 to Trial 3, the result is increase. After that, for ml volumetric flask the result is decrease from Trial 1 to Trial 2 but increase from Trial 2 to Trial 3. For ml measuring cylinder, the result is decrease from Trial 1 to Trial 3. When the results are compared to he theory, we can conclude that our result for experiment is not accurate but precise. It is not accurate because of the different pressure from surrounding. But then, the results are precise because all the measurement recorded shows the same results. From this experiment, there are possible error occur. Firstly, error occurs during measure on electronic weigh balance. Second, the apparatus is not dry and cleaned in a proper way. Third, parallax error occurs during measure the apparatus. CONCLUSION In conclusion, this experiment is conducted to investigate how to calibrate the quid accurately and precisely by using volumetric glassware. In order to study the problem, we did three complete trials for each of the calibration of volumetric glassware. My results showed that the trial with the highest relative standard deviation was 100 ml volumetric glassware while the lowest greatest relative standard deviation was 50 ml measuring cylinder. This can conclude that the accuracy of the volumetric glassware is affected by the sensitivity of the instruments. In order to overcome the error, we have to make sure that the eye position is perpendicular to the reading scale of the apparatus to avoid parallax error. Besides that, the beaker should be clean and dry properly so that there is no water left which can affect the mass of the next trial. Apart from that, the volumetric glassware should be weight properly in order to get the accurate and precise results. APPENDIX Questions 1 . Please tell in simplest way what calibration is.. Calibration is a comparison between measurements which is known as magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device. 2. Draw a flowchart for the calibration of 50 ml measuring cylinder. . With the reference to the capacity of the glassware you have chosen, give a set of reading to illustrate the meaning of good accuracy and poor precision. With reference to the capacity of the glassware you have chosen, give asset Accuracy is how close the measurement is to the actual measurement. Good accuracy and poor precision means the readings of the measurements are not particularly close to each other but the readings are close to the actual reading of the glassware chosen. Example: The capacity of the measuring cylinder is ml. The measurements taken: 48. Ml, 50. Ml, 49. Ml, 47. Ml, ml, 50. Ml. This distribution shows no impressive tendency toward a particular value (lack of precision) but each value does come close to the actual volume (high accuracy). . What does standard deviation, o, indicate? The standard deviation is a measure that summaries the amount by which every value within a dataset varies from the mean. Effectively it indicates how tightly the values in the dataset are bunched around the mean value. It is the most robust and widely used measure of dispersion since, unlike the range and inter- quartile range; it tak es into account every variable in the dataset. When the values in a dataset are pretty tightly bunched together the standard deviation is small.

Countries That Lie on the Earths Equator

Countries That Lie on the Earths Equator Although the equator stretches  24,901 miles  (40,075 kilometers) around the world, it travels  through the territory of just 13 countries- and yet the landmasses of two of these countries do not touch the Earths  equator. Did You Know? The equator is an imaginary line that circles the Earth, splitting it into northern and southern hemispheres. Any location that lies along the equator is equidistant from the North and South Poles. The 13 Countries That Lie on the Equator Of the 13 countries that lie on the equator, seven are in Africa- the most of any continent- while South America is home to three of the nations (Ecuador, Colombia, and Brazil). The remaining three (Maldives, Kiribati, and Indonesia) are island nations in the Indian and Pacific oceans.   The countries of Sao Tome and Principe, Gabon, Republic of the Congo, the Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia, Kiribati, Ecuador, Colombia, and Brazil all lie along the equator. The landmasses of Maldives and Kiribati, however, do not touch the equator itself. Instead, the equator passes through water controlled by these two island countries. Latitude and Longitude The equator is one of five lines of latitude that help provide relative locations on an atlas. The other four include  the Arctic Circle, the Antarctic  Circle, the Tropic of Cancer, and the Tropic of Capricorn.  Because the Earth bulges at the center, the equator is significantly longer than any of the other lines of latitude. Along with the lines of longitude which run from pole to pole, they make it possible for cartographers and navigators to locate any spot on the globe. The plane of the equator passes through the sun at the March and September equinoxes. The sun appears to travel directly north to south over the equator at these times. Because of this, people living along the equator experience the quickest sunrises and sunsets as the sun travels perpendicular to the equator most of the year, with the length of days being almost entirely the same throughout- daylight lasting 14 minutes longer than nighttime. Climate and Temperatures Most countries that lie along the equator experience much warmer temperatures year-round than other areas of the world that share the same elevation. Thats because of the equators near-constant exposure to the same levels of sun exposure regardless of the time of year. As a result, the countries that lie along the equators include almost half of the worlds rainforest; they are concentrated in the African nations of Congo, Brazil, and Indonesia. Even so, the equator offers a surprisingly diverse climate due to the geographical features of countries that lie along it. There is little fluctuation in temperature throughout the year, though there may be dramatic differences in rainfall and humidity, which are determined by wind currents. In fact, the terms summer, fall, winter, and spring dont really apply to regions along the equator. Instead, people who live in the especially humid tropic regions refer to only two seasons: wet and dry. Equator Extremes Its reasonable and largely accurate to assume that the weather is uniformly warm or hot around the equator. But of course, weather and climate relate not only to latitude but also to geography. Some countries that lie on the equator are flat and warm but others, like Ecuador, include high mountains where the weather is extremely cold. In fact, you will find snow and ice year-round on  Cayambe, a volcano in Ecuador that reaches to 5,790 meters (nearly 19,000 feet). It is the only place on the equator where snow lies on the ground year-round.

The Message of the Torah Essay Example | Topics and Well Written Essays - 750 words

The Message of the Torah - Essay Example Therefore, it is kept and dressed in Synagogue. The significance of Torah can be substantiated by the message conveyed in it, which is about blessing i.e. God will always bless human beings1; which contains an abysmal severity of magnitude and importance for the mankind, particularly the followers. The literal meaning of the term Torah is to teach. The book teaches Jewish people how to pray, eat, and live2. The message of the Torah is that God provides all that mankind needs and give commands to choose the way of life. â€Å"The Torah conveys the message that God has blessed the humanity by providing them the required guidance in the form of this scripture† â€Å"male and female created He them, and blessed them, and called their name Adam, in the day when they were created â€Å"3 The Torah delivers the message that God has blessed us by keeping us alive and sustained in this earthly environment. The message it conveys is about self-satisfaction. Everything that human beings need in order to be happy has been provided by God. No matter how many difficulties we face in our lives, the recitation of Torah will fill ourselves with happiness and satisfaction. This shows that Torah is the source of solace and a means to achieve contentment in this highly materialistic world of today. In the present times, when materialism has heightened to extreme extents, individuals have forgotten to find happiness in nature and to be thankful with what one has. Torah acts as a reminder which aids to achieve contentment and inner peace. â€Å"and He said: If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in His eyes, and wilt give ear to His commandments, and keep all His statutes, I will put none of the diseases upon thee, which I have put upon the Egyptians; for I am the LORD that healeth thee†4 The central message is predominantly preoccupied with human actions. It further teaches individuals to follow the commands of God

Kublai Khan Essay Example | Topics and Well Written Essays - 2500 words

Kublai Khan - Essay Example As Emperor, Khan initiated a symbiotic relationship between the Chinese and the Mongols, promoting a nation of tolerance and cross-cultural interaction that allowed for a flourishing of diverse arts as well as militaristic might. He exercised both military and political savvy in his actions, which contributed to a successful unification of the two primary peoples of his empire. Kublai’s power, military and political success attests to his military intelligence and daring. He was a strong man who understood strategy and possessed the ability to command respect and obedience from his subjects and people, ruling with a strong hand when necessary and promoting tolerance when possible. It was in this latter instinct that he gained perhaps his most lasting contributions, but it is also that instinct that nevertheless led to his downfall. Although he likely would not have been as successful as he was, had he not possessed political intelligence and agility, his instincts were often t owards indulgence of this tendency. He well understood the profound importance of catering to the Chinese majority, and thus took on Chinese advisors and officials as well as made a point of upholding important Chinese traditions, cultural values, and administrative practices. He commanded all his concubines, sons, daughters, and all the royal family members to adopt the Han culture and acquire the Chinese language and customs. Thus, the new China flourished under Kublai’s rule and experienced a heavy restructuring of political configuration. However, although Kublai Khan overcame many difficulties and barriers and ultimately achieved what he endeavored to do, in the end he became a disillusioned and embattled man. Through the struggles to convince his own conservative Mongol community of the need for the tolerance he promoted with the Chinese culture, he was increasingly isolated and frustrated at the end of his life. Both his military and political strength portrays his cap acity for leadership and as well as his ability to properly run a nation and allow it to flourish, but his personal failures and ideas eventually left lonely and embittered. In this essay, his contributions and legacy will be reviewed in order to see this in more depth. Family Background and Early Beginnings Genghis Khan, Kublai’s grandfather, united many of the nomadic tribes of northeast Asia and in that way founded the Mongol Empire. As Paul Ratchenevsky writes, the nomadic tribes in their territory were loosely linked tribal groups who would make stronger but still temporary confederations whenever some regional purpose called for it. Such purposes often involve war, but these were traditionally wars of a defensive nature. The tribal bands would come together whenever an outside force posed some impending danger, but their need for mobility as nomadic peoples generally prohibited any stronger or more lasting associations because of the nature of their lifestyles. Genghis Khan, through force of personality and visionary leadership managed to unite these tribes and begin offensive wars that allowed the empire to expand across Asia. Eventually, he initiated many invasions within Eurasia, thereby extending the reach and impact of his territory. In these ways, he was to be emulated by his grandson, with a combination of imaginary and charismatic leadership that led to the establishment of greater territories. Through the influence of Genghis Khan,

Ratio Analysis to Determine Corporate Health Essay Example for Free

Ratio Analysis to Determine Corporate Health Essay One must consider many factors before deciding whether or not to invest in a company. The following is an analysis and comparison of the health of two well known companies, Exxon and Wal-Mart. Some of the factors that were analyzed include current ration, inventory turnover, accounts receivable turnover, and days’ sales in inventory. Most of the values used for the calculations were obtained from Yahoo Finance. Current ratio evaluates a company’s ability to pay its short-term obligations (Wild, 2008). Exxon’s current ratio of 1. Â  indicates that it should not have any issues paying its short-term obligations. In contrast, Wal-Mart’s current ratio of 0. 88, indicates that the company’s current liabilities exceed current assets and thus investors should be doubtful of its ability to pay short-term obligations. Inventory turnover is another indicator of a company’s ability to pay short-term debt. Specifically, it is the number of times a company’s average inventory is sold during a period (Wild, 2008). Wal-Mart’s inventory turnover of 9. Â  indicates that it may be holding more inventory than it needs, and thus it may be using its assets in efficiently. Exxon’s inventory turnover of 28. 31 is more preferable, as long as inventory adequately meets demand (Wild, 2008). These numbers show that Wal-Mart may be having difficulties paying its short-term debt and thus caution should be warranted. Accounts receivable turnover measure the quality and liquidity of accounts receivable. Thus it indicates how often receivable are received and collected during the period (Wild, 2008). Exxon’s accounts receivable turnover is 15. Â  while Walmart’s is 107. 3. Exxon’s low turnover suggests management should consider stricter credit terms and more aggressive collection efforts to avoid its resources being tied up in accounts receivables. On the other hand, Wal-Mart’s high turnover implies the opposite; management should consider using more liberal credit terms. While accounts receivable turnover measures the liquidity of accounts receivables, days’ sales in inventory is useful in evaluating liquidity of inventory (Wild, 2008). Exxon’s days’ sales in inventory is 13. 2 and Wal-Mart’s is 38. Â  Exxon’s lower days’ sales in inventory value indicates that the company uses its resources more efficiently. Conclusion All things considered, Exxon appears to be a more solid company in which a first time stock-buyer should invest. While both are major companies, which appear to have solid numbers, Exxon seems to be the more stable and reliable company. Specifically Exxon seems to manage its assets better and seems more likely to be able to pay its short term debt. Nonetheless, one should invest in stock that he or she feels better represents his or her goals.

Marfan Syndrome Essay -- Health, Diseases

Marfan syndrome is a primarily an autosomal dominant disorder that affects 1 in 5000 people worldwide. Marfan syndrome is connective tissue disorder that results in a mutation in the Fibrillin 1 gene. The life expectancy of an individual with Marfan syndrome is close to normal with early detection, but Marfan syndrome still remains underestimated due in large part to characteristics similarities that are common in general public. This is compounded by the 25 percent of individuals with a new gene mutation on Fibrillin 1. It is imperative that nurses have a greater understanding of Marfan syndrome in order to facilitate a genetic referral for an early and accurate Marfan syndrome diagnosis. This should include the mechanism of how this genetic mutation manifests thought out the body, the presenting symptoms, the risk factors, treatment, and education needs of the patient. Marfan syndrome Marfan syndrome (MFS) is a fairly common inherited connective-tissue disorder. The syndrome can be found in 1 in every 5000 births worldwide (Giarelli, Bernhardt, & Pyeritz, 2010). MFS has been recognized for more than 100 years, in fact it was speculated that Abraham Lincoln had the disorder (Amado & Thomas, 2002). There is still no current cure, but early recognition and intervention can play a key role in the prevention of the sudden cardiac complications (Midla, 2008). For those Marfan patients diagnosed the life expectancy is close to normal, yet tends to be under diagnosed (Pyrietz, 2000). The nurse should have a broader understanding of MFS since recognition is essential for the diagnosis. Since MFS is primarily an inherited disorder, it of equal importance that the nurse understands that a referral to a geneticist is an imperative n... ...ssion, and anxiety can occur (Giarelli et al., 2010). Athletes who wish to play sports should have a clinical and cardiac evaluation before allowed to play. Women who are considering getting pregnant should be given have a cardiovascular risk assessment before conceiving and genetic counseling should be recommended to establish the patient’s risk of passing on the syndrome (Lippincott Williams & Wilkins, 2005). While significant advances have provided MFS patients with a greater life expectancy, the fact still remains that early detection is imperative in improving of care for the MFS patient . As MFS patients live longer and symptoms become evident. Nurses need to recognize that these patients will often present in a routine clinical setting, where their clinical expertise and genetic knowledge may open the door to early diagnosis and treatment.

On the Necessity of Rationalism

In the process of considering the various means of justification, a relativistic conception of reality assumes that the truth and hence the validity of a statement may only be assessed in relation to the perspective of the discipline which holds a particular belief. In this sense, truth is dependent upon the internal coherence of beliefs within a system of thought. In his The Last Word, Nagel claims that such is not the case. He argues that the truth and hence the validity of statements are dependent upon an unqualified notion of reason.He claims that the truth of a statement is independent upon any particular perspective. If such is the case, it follows that the truth of any statement is independent from the schema [truth schema] presented by any system of thought. In relation to scientific claims, it thereby follows that the truth of scientific claims ought to be assessed through the unqualified notion of reason as opposed to merely their internal coherence within the scientific co nception of reality [scientific framework].The aforementioned argument is based upon the critique of the intrinsic limits to subjectivist doubt since challenges to the independent validity of reason must themselves assume the independent validity of reason. Any explanation of reason deriving from outside the mind can itself be explained only from inside the mind, as having its own independent validity. In the case of scientific knowledge, he argues that it is mistaken to assume that the scientific discipline has freed itself from the limits of the Cartesian problem through the replacement of judgments about rules of practice from objective judgments.Nagel argues that if science will continually adhere to a subjectivistic and hence relativistic framework, the discipline will fail to provide an objective account of reality. He claims, â€Å"the general aim of such reasoning [scientific reasoning] is to make sense of the world in which we find ourselves and how it appears to us and ot hers† (81). If such is the case, it is necessary to conceive of the conception of the world which is not based upon an a priori conception of reality dependent upon a preconceived and limited conception of the word. According to Nagel, such an account is not provided by science.The reasons for this lies in the subjectivism of science (Nagel 84). Subjectivism within science [scientific methods] is apparent if one considers that the scientific â€Å"demand for order cannot itself be rationally justified nor does it correspond to a self-evident necessity† (Nagel 84). He notes that scientific subjectivism can only end if it adheres to rational means of knowledge acquisition. It is only through the defense of rationalism that an objectivist account of evidence is possible.Nagel further argues that the appeal of subjectivism arises out of a certain reductionist impulse in modern explanation as this reductionist impulse enables the explanation of things to hinge on their reduc tion to local and finite terms thereby ensuring subjectivist conclusions. Although this enables the assurance against rationalist explanations that refuse to make reason into something irrational or that conceive of reason as a capacity for grasping the universal and infinite principle, the reductionist explanation is in itself dependent on an irreducibly nonlocal and objective understanding of reason. Nagel argues that doubt about reason presupposes reason’s independent validity hence reason’s independent validity cannot be coherently doubted.He rightly argues that to object to reason on the grounds we cannot strictly explain it in naturalistic terms is to misunderstand the irreducible nature of the concept since reason cannot be so explained without losing its meaning or validity and that, as such, it is justified in a different way, by showing it to be necessary to intelligible thought and action. Science thereby must opt for a rationalistic as opposed to a subjecti vistic account of reality for it to maintain its value as a discipline.Work CitedNagel, Thomas. The Last Word. New York: Oxford University Press, 1997.Essay Number TwoEdmund Gettier’s Counterargument Against thePlatonic Tripartite Account of Propositional KnowledgeThe Platonic tripartite definition of propositional and fallibilist knowledge found in the last section of the Theaetetus states that knowledge of P occurs when an epistemic agent S knows that P if and only if (1) P is true, (2) S believes that P, and (3) S is justified in believing that P (90). A well-known opposition to such an account of propositional knowledge questions the sufficiency of the aforementioned conditions.It is argued that although the aforementioned conditions are necessary in the definition of propositional knowledge such conditions are insufficient due to their failure to ensure S against conditions wherein knowledge of P occurs as a result of mere epistemic luck (Gettier 123). This critique is b est known as the Gettier type counter examples towards the tripartite definition of propositional knowledge mentioned above.A logical problem is posited by the Gettier type counter examples. This logical problem is evident in the lack of successful coordination between the truth of P and the reasons that justify S in holding P. Floridi notes that Gettier type counter examples arise â€Å"because the truth and the justification of P happen to be not only independent but also opaquely unrelated that they happen to fail to converge or agree on the same propositional content P†¦without S realizing it† (64). In order to understand this, it is important to lay down the main assumptions of Gettier’s counter argument that seeks to explicate the aforementioned logical problem.Gettier’s argument against the tripartite account of propositional knowledge, which involves the conception of knowledge as justified true belief arose as a result of the following claim: knowl edge [propositional knowledge] does not merely involve justified true belief. Such a claim is based upon the following assumptions. First, there are instances wherein the warrant is not a sufficient condition for a belief in P. This is evident if one considers that instances of belief and knowledge of P are in some respects epistemically different [other than in terms of truth] from belief of P without knowledge of P. Second, there are instances wherein warrant is fallible.This is due to the insufficiency of truth and justification as warrants for knowledge. The evidence of such, according to Gettier is apparent if one considers that it is possible for P to be false even if S believes that P possesses epistemically significant properties such that whenever a belief possesses such properties and is true the belief may thereby qualify as knowledge. Lastly, there is the closure of knowledge under obvious and known entailments. The last assumption argues that if S is justified in believ ing P and a deductively valid inference is drawn from P to another belief Q then S is justified in believing Q. This is a result of the entailment of Q from P.From what was stated above, it is possible to present the usual form of Gettier’s attack against the tripartite account of knowledge. Gettier’s counter argument is based upon the critique of warrant, fallibility, and closure. Note that combination of the three claims mentioned above leads to a contradiction. From what was mentioned above it follows that it is possible to believe in an obvious deductive consequence of P, which is Q, while in the process retaining the epistemically significant properties of the belief in P.If such is the case, it is possible to have a justified true belief of any property which has led S to have a belief in Q or any other type of belief which has Q’s epistemic characteristics. Note that this contradicts the assumed necessity that P and Q differ from each other since one qual ifies as knowledge [S believes and has knowledge of P] whereas Q merely qualifies as a belief [S believes but does not have knowledge of Q].Works CitedFloridi, L. â€Å"On the Logical Unsolvability of the Gettier Problem.† Synthese 142(2004): 61-79.Gettier, E. â€Å"Is Justified True Belief Knowledge?† Analysis 23(1963): 121-23.Plato.

Paulo Freire Essay

The chapter provides detailed overview of life and activities of Paulo Freire. The chapter is of historical and cultural significance, because it aims at expanding existing knowledge about one of the key figures in history. It goes without saying that Paulo Freire is considered one of the most respected and known persons in the history of radical education. The chapter starts from biography of famous educator and proceeds to his activities, occupations and career in related sphere. Firstly, it is necessary to admit that Paulo Freire was born in Brazil, Rectife, in 1921 and he spent many years working in poor regions of his homeland. Therefore, he was aware of poverty and difficulties connected with it. Actually, he couldn’t remain indifferent to people’s suffering and decided to develop methods how to teach illiterate people. It is a common knowledge that many poor people in those times didn’t known how to read and to write. Freire decided to devote his life to improve literacy among poor population. He taught not only children, but also adults how to think critically and, what was more important, how â€Å"to take power over their lives†. Moreover, he created his own classroom to make the process of teaching more comfortable, easier and more interesting. Students and teachers in that class were provided with equal rights and power. They were treated with dignity and respect. Such method of teaching was later considered a model for educating around the world. The net moment to mention is that Paulo Freire taught people in Europe, the United States of America. He worked even for the government in Chile. There, as it is mentioned, he â€Å"trained the teachers whose job it would be to bring modern agricultural methods to the peasants†. Of course, Freire’s mission is honorable and should be respected. He worked out education programs for UNESCO, World Council of Churches, the Chilean Institute of Agrarian Reform, etc. Further, his famous works are â€Å"Education for Critical Consciousness†, â€Å"The Politics of Education†, â€Å"The Pedagogy of the Oppressed†, etc.

Nurse Practitioner vs. Registered Nurse What’s the difference

Nurse Practitioner vs. Registered Nurse What’s the difference You’ve probably heard that nursing jobs are hot right now. And it’s true. But even within the general nursing world there are tons of specialties, so it’s important to know who does what before you commit to the career path. There are emergency nurses, pediatric nurses, travel nurses, nursing assistants, etc. You name the health care specialty, there’s probably a specific type of nurse attached. But what about nursing jobs that aren’t as clear? If you’re not yet super-familiar with different kinds of nurses, you may hear â€Å"registered nurse† and â€Å"nurse practitioner† and think that the terms are interchangeable. After all, both types of nurses work with patients to monitor their health and provide direct medical care. Let’s walk through how to tell the difference between these two important nursing careers.Prescribing medicineNurse practitioners have greater flexibility when it comes to prescribing medicine and per forming duties normally handled by physicians. Licensed nurse practitioners are legally able to prescribe medications and have greater flexibility in diagnosing and treating illnesses. Registered nurses cannot prescribe medications and often work under the direction of a physician when it comes to determining patient care and follow-up.Work environmentNurse practitioners often work in more private practice-style settings like community clinics, government agencies, nonprofits, or educational settings. A nurse practitioner may take on more of a physician-style in a clinical setting. Registered nurses typically work in hospitals or surgical clinics. Because of the nature of private clinics vs. the realities of working in a hospital, nurse practitioners often have more standard hours, while registered nurses work a greater variety of shifts.Level of educationRegistered nurses usually need a bachelor’s degree in nursing to get started in the field, but nurse practitioners typical ly hold a master’s degree or higher. This makes nurse practitioner a logical next step for nurses who’ve been in the field for a while and want to take on more of an independent leadership role. But it can also mean additional investment of time and resources in an additional degree, so it’s important to consider whether becoming a nurse practitioner is truly what you want to do.SalaryBecause of the additional education and training for nurse practitioners, salaries tend to be higher for nurse practitioners than registered nurses on average. Per the U.S. Bureau of Labor Statistics, registered nurses make a median annual salary of $68,450 per year, while nurse practitioners take home a median annual salary of $100,910.If you’re thinking about a career in nursing, both nurse practitioner and registered nurse have the potential to be great, fulfilling career options. And if you’re not sure yet which one would better suit your career goals, we have a q uiz for you to help figure out your next steps. Good luck!

35 Literary Devices and Literary Terms (with Definitions and Examples)

35 Literary Devices and Literary Terms (with Definitions and Examples) 35 Literary Devices and Literary Terms (with Definitions and Examples) A clear list of literary devices is a good resource for any writer to have on hand. Strong device usage can help elevate a book from a story people forget, to a piece of literature that stays with them long after they've turned the final page.After all, in  As You Like It, Shakespeare could have simply written, "Everyone has a role in life." But instead, he used a literary device and penned one of the famous metaphors of all time:All the world’s a stage And all the men and women merely playersAnd the rest is history. 35+ literary devices to turn you into Shakespeare What are literary devices?Literary devices are tools writers use to express their ideas with artistic depth. These devices can clarify and emphasize concepts, create resonance within a narrative, and invite readers to dig a little deeper into the story’s themes.While all of the tools below fall under the umbrella of â€Å"literary devices,† the purpose and impact of them varies wildly. Some might underscore a narrative and work on an intellectual level, while others have more of a subtle, visceral, or emotional effect. Finally, they might also work to simply enhance the flow and pacing of your writing. No matter what, if you're looking to inject something special into your prose, literary devices are a great place to start. You can also check out our list of 30 rhetorical devices right here!List of literary devices1. AllegoryThe Tortoise and the Hare is about more than just a turtle, a rabbit, and a race. It also aims to teach the lesson: slow and steady wins the race. That’s what an allegory does  - it’s a type of narrative that uses characters and plot to exemplify abstract ideas and themes, such as patience. In an allegorical story, events and characters tend to represent more than they appear on the surface.Example: Animal Farm by George Orwell. This dystopian novella is one of modern literature’s best-known allegories. A commentary on the events leading up to Stalin's rise and the formation of the Soviet Union, the pigs at the heart of the novel blatantly represent figures such as Stalin, Trotsky, and Molotov. Litotes (pronounced lie-toe-teez) is the signature literary device of the double negative. Writers use litotes to express certain sentiments through their opposites, by saying that that opposite is not the case. Don’t worry, it makes more sense with the examples.
