Jacob Have I Loved Essays - Jacob Have I Loved, Human Behavior

Jacob Have I Loved Jacob Have I Loved is a great book for any child that resents their siblings, because thats how this twin sister relationship is best described. Sara Louise recalls her difficult adolescence on Rass Island and her intense jealousy of her own twin sister Caroline. Caroline is a selfish, over protected person and Sara Louise feels like her life is based on competing with the most admired sister Caroline. Caroline always got what she wanted and was considered to be the attractive one, smarter one by her mother and grandmother. Foe example one day before attending church when Sara Louise unexpectedly became a woman she stained her Sunday dress and couldnt go to church, her grandmother had a cocky attitude because she couldnt attend church that day. But when Caroline had her period she was congratulated Thats just many of the trails that made Sara Louise stronger throughout the book. Caroline is assumed to be the better sister, but in reality Sara Louise is the independent and strong sister, she never let anything stand in her way. When Caroline needs other people for almost every thing and is surprised when she doesnt get her way. For example, Sara Louise and her best friend Call, Call thought Caroline was attractive but rarely played with her. He liked Sara Louises personality, she wasnt fake and didnt pretend to be someone shes not. But when Call came back married to Caroline from the war, all of Sara Louises dreams were lost, but still remained friends with Call and kept going on and on. Yet another example of Sara Louises strengths. This book emphasizes with Sara Louise and helped me see her point of view and better understand that all people have their own talents that they may not have discovered yet. This twin sister relationship was based off of jealousy and beauty that would have never have been if they were both treated equally and their mother and grandmother didnt play favorites.

Concept and Importance of the Positive Thinking

Concept and Importance of the Positive Thinking Positive thinking refers to the act of directing one’s mind to constructive thoughts that deviate from negativity and that are characterized by hope and expectations for better things in life (Quilliam, 2008, p.21).Advertising We will write a custom essay sample on Concept and Importance of the Positive Thinking specifically for you for only $16.05 $11/page Learn More Its development involves constant practice and persistent efforts. Positive thinking is important in life because it helps manage and eradicate stress, gives more energy to carry out daily activities, improves relationships, creates peace of mind, fosters a healthy lifestyle and guarantees success (Farreer, 2004, p.18). In addition, it enhances personal happiness and fulfillment, gives hope of a better future and aids in time management and personal organization. Positive thinking is vital in management and eradication of stress in life. This comes from the habit of looking and handling things positively. It enables a person concentrate on things that create a better life and enables an individual let go of situations that are either wearisome and distressing (Peale, 2012, p.32). Stress comes from constant worry and frustration with life situations that do not serve a person’s purpose in life. Positive thinking leads to the realization that negative thinking creates more problems and complexities in life than are unnecessary. Positive thinkers are able to evaluate problems and come up with appropriate solutions while negative thinkers see problems and resign to fate because they consider them difficult and impossible to solve. Positivity keeps stress out of life and improves a person’s well being. Positive thinking improves relationships by making it easier to connect with other people. People hate negative thinkers because they focus their energies on the wrongs of life and rarely recognize the good present, which if acted upon, can improve life in a great way. Positive thinking helps build deeper and better relationships that are founded on trust, great understanding and support (Peale, 2003, p.54). In addition, this helps create a healthier lifestyle because being at peace with friends, family and society gives peace of mind that is important for a good life. It eradicates anxiety and fear because of the feeling of belonging and worth created by being at peace with every one (Peale, 2012, p.61). In addition, it creates a good mood that appeals and attracts others thus enhancing good relationships. Spending more time with positive people is important in creating better relationships. Good time management and organization is a direct result of positive thinking (Peiffer, 2002, p.77). The inward organization of thoughts reflects the outward organization of a person’s life. As such, if a person organizes his thoughts through positive thinking, then he is able to organize other aspects of life. This organization improves ef ficiency and leads to good time management. A positive thinker has no time to waste because all activities are planned based on time allocated for those specific activities. Good time management can be achieved through prioritizing and focusing on the most important things.Advertising Looking for essay on ethics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Life situations are complex and demanding. Therefore, energy is a requisite for effectiveness and high productivity. Positive thinking avails more energy to carry out life activities because it reduces fatigue that is caused by stress (Peiffer, 2002, p.84). Stress and negativity drain the energy needed for life accomplishments by bringing feelings of disinterest and boredom, fatigue and create bad moods. Finally, positive thinking guarantees success because an individual is able to prioritize and focus on important things (Sasson, 2012, p.66). In addition, peace of mind improv es concentration on tasks that determine success and well-being. References Farreer, G. (2004). A Gift of Positive Thinking. New York: Andrews McMeel Publishing.

BSN & MSN Program Essay Example | Topics and Well Written Essays - 750 words

BSN & MSN Program - Essay Example Moreover, the curricula designed for the bachelors degree programs in nursing are quite different from the curricula designed for the masters programs in the same field even though they may be offered in the same institution. This paper analyzes and compares the nursing degree curricula that are used for undergraduate programs as well as for the masters programs in nursing within a university college. Moreover, the paper will evaluate the curricula programs and education outcomes postulated by these designed curricula with an aim of establishing how the undergraduate programs and the postgraduate masters programs in nursing profession build on each other. II. Difference in Outcome and Content The BSN as well as MSN programs have competitive provisions that are all geared towards the production of holistic and competitive nursing professionals. There is little notable difference though between the curricula content and the outcome as shown by the nursing regulatory and management bodi es. The visionary track of a nursing education follows through the levels of a generalist, an advanced generalist that is later followed by specialization programs. The generalist nursing education is what is offered at an undergraduate level while the advanced generalists refers to what is offered at the masters level programs. ... include ‘scholarship for evidence based practice’ ‘liberal education for baccalaureate generalist nursing practice’, and‘basic organizational and systems leadership for quality care and patient safety’ (Anon, 2008). ‘Information management and application of patient care technology, healthcare policy, finance, and regulatory environments’, ‘inter professional communication and collaboration for improving patient health outcomes’ and ‘clinical prevention and population health’(Anon, 2008). Moreover, ‘professionalism and professional values and baccalaureate generalist nursing practice’ (Anon, 2008) form part of these essentials. The major notable difference between these essentials for the undergraduate programs in the contents and the outcomes expected from the courses offered. On the other hand, the masters programs in nursing education equally run on stipulated essentials, which define the el ements of the adopted curricula not based of such factors as intended practice settings, focus or major. Masters programs differ in regard to the undergraduates in that they employ programs which are different in content in order to have variations in outcomes. The outcomes for masters programs are professionals who besides practicing can address available gaps in the field. The masters essentials are ‘background for practice from sciences and humanities’, ‘organizational and systems leadership’, ‘quality improvement and safety’ and ‘translating and integrating scholarship into practice’(Anon, 2011). Moreover, ‘informatics and healthcare technologies’, ‘health policy and advocacy’, ‘inter professional collaboration for improving patient and population health outcomes’, ‘clinical prevention and population health for

To investigate the factors that affect rate of reaction Essay Example for Free

To investigate the factors that affect rate of reaction Essay I will pour one lot into the glass phial, I will then measure out five different concentrations of acid. I will do this by using a two molar acid and will vary the ratio of water, the combinations will be: Acid Water 25 ml 0 ml = 2 molar 15 ml 5 ml = 1. 6 molar 12. 5 ml 12. 5 ml = 1. 2 molar 10 ml 15 ml = 1 molar 5 ml 10 ml = 0. 8 molar Then I will pour the two molar acid into the phial, put the cork on and start the timer as soon as the cork is in place, so we are able to start timing when gas is being collected and not before as this would make it an invalid result of the first ten seconds. I will repeat this process for each concentration. After each experiment I will rinse out the phial, to make sure the marble chips wont start reacting before I pour the acid in. I will record the measurement from the syringe every ten seconds by folding the tube over to stop the gas from escaping through, and will empty the syringe of gas after each experiment. Trial Run Below is a results table showing our first trial run of our plan of action so I can see if anything needs changing. Concentration g/dm3 Time (s) 2 molar 1. 6 molar 1. 2 molar 1 molar 0. 8 molar. These results do follow the pattern predicted so I will not change my plan of action for the real experiment. Apparatus . 5 measuring cylinders to measure out the different concentrations . Water . 2 molar acid . syringe to measure the gas produced . 5 lots of small marble chips each weighing 2. 5 grams . Electronic weighing scales to weigh out the marble chips. 5 beakers to hold the marble chips . Rubber tube with a cork attached to capture the gas produced . A phial to hold the marble chips with the acid whilst reacting . Stop clock to take readings every 10 seconds Fair Test I will make sure it is a fair test by rinsing out the phial after each reaction has taken place so the next lot of marble chips wont start reacting before the experiment begins. I will use the same bottle of 2 molar acid to make sure I dont use slightly different concentrations and will repeat the experiment three times to get a good average of the results. Also I will use the same measuring cylinders so I will be measuring to the same nearest ml each time. Method . Make sure you have all the equipment stated in apparatus list . Weigh out five lots of 2. 5g of marble chips . Measure out the five different concentrations . Pour one lot of marble chips into the phial . Pour acid in the phial with the chips and place on the cork . As soon as cork is in place start the stopwatch . Every 10 seconds record the gas measurement from the syringe . Rinse out the phial and repeat for each concentration . Record all results on a table SAFETY BOX. Wear goggles and aprons to protect from acid spillage . Keep lid on acid when not in use . Make sure bags and coats are out of the way Results Concentration g/dm3 Time (s) 2 molar 1. 6 molar 1. 2 molar 1 molar 0. 8 molar Concentration g/dm3 Time (s) 2 molar 1. 6 molar 1. 2 molar 1 molar 0. 8 molar Average Results Here is a table showing the average of the three sets of results that I have recorded: Concentration g/dm3 Time (s) 2 molar 1. 6 molar 1. 2 molar 1 molar 0. 8 molar   Results Table for Rate Of CO2 Production Concentration g/dm3 ( Rate Of CO2) Time (s) 2 molar 1. 6 molar 1. 2 molar 1 molar Evaluation Overall I think that my results are reliable but not as accurate as they could be. Reasons for this are that the measuring cylinder for measuring the acid and water was only accurate to 0. 5ml and the syringe to measure the production of CO2 gas was only accurate to 1ml, or more with the human eye reading it. The balance to weigh out the small marble chips was very accurate to 0. 01g but there was no guarantee that the surface area was the same which will have affected the results. Starting the stopwatch at exactly the same time for each experiment was impossible and will have varied each time affecting the first 10 second readings. In my theory I mentioned about temperature effecting the rate of a reaction, and the room temperature wasnt the same each day during the experiment so this will also have added inaccuracys. Due to human error the gas may have leaked out through the tube whilst we were trying to read from the syringe resulting in us reading more then what we should have. With all this taken into account I have concluded that although my results follow the patterns and trends predicted they arent very accurate. If I was to do the experiment again then I would have the same amount of marble chips as well as the same weight as this would make the surface area more accurate. I would also do the experiments all in one day so that the temperature would be roughly the same. Also I would probably use a different method of tracking the mass instead of displacement. I would do this because although displacement is very clear and simple, it can also be very inaccurate and is read through the human eye, whereas mass loss would be done with a machine and would be extremely accurate. I have found no anomalous results as each graph follows the trends and patterns expected. My graphs clearly illustrate that my theory was correct. The collision theory in particular as this was the factoral that we were changing (concentration). The higher the molarity the more particles there were in the same volume of water so the faster the reaction. As you can see from my graphs that the higher the molarity went the faster the gas was produced. Conclusion In conclusion the experiment went very well and I have proved that my theory was correct and that my results are reliable. You can see this from the graphs present.

Films that were enjoyed and disliked :: essays research papers

Films that were enjoyed and disliked   Ã‚  Ã‚  Ã‚  Ã‚  The DVD The Movies Begin by Kino video is a testament to the early beginnings of film history. The series outlines man’s earliest attempts to create visual representations of the world around them, with great success. There are many short films on the disc that range from real events to staged minute long â€Å"stories.† There are some films that are enjoyable on levels of artistic creativity, while others lack motivation and are tedious (despite their short length).   Ã‚  Ã‚  Ã‚  Ã‚  The film that sticks out most in terms of creativity is Georges Melies’ A Trip To The Moon (1902). This film chronicles the short but adventure filled flight of men to the moon. They make a large steel vessel, and travel to the moon where they encounter hostile alien beings. The film gave early audiences the fantasy of what was at the time impossible. This was primarily because of the use of special effects and a creative set design. This happened to be the result of Melies’ work as a magician. He also made use of editing to aid in his visual interpretation, making the audience believe that the aliens mysteriously evaporated after being hit with an umbrella. Melies also created a structure that was comprehensible. A simple venture into space; aliens and danger; escape to earth. This seemed to represent the three-act structure comparable to today’s films. All these elements created a landscape most audiences had never envisioned.   Ã‚  Ã‚  Ã‚  Ã‚  Another short film that warrants mention for simple creativity yet has underlying political tones is Ferdinand Zecca’s The Golden Beetle (1907). This film uses special effects as its main draw, showing a man enticed, then killed by a beautiful woman (beetle). Color tints on the film gave it an unusual look, as the woman appears to have an aura of gold around her body. The film’s climax sees the demise of the man in a fiery death. This was most probably the result of the cultural attitudes toward women during this period. The film suggests that a woman could be mysterious and alluring, yet simultaneously destructive and overwhelming.   Ã‚  Ã‚  Ã‚  Ã‚  One film that was pioneering in its technical attributes was the Lumiere brothers’ film Leaving Jerusalem By Railway (1896). This was a short film where the camera was at the rear of a train as it pulled away. This was revolutionary for the period because it took the camera away from the common stationary position somewhat, creating a tracking shot.

Chemistry Notes

Everything is made of particles. Particles in solid are not free to move around. Liquids and gases can. As particles move they collide with each other and bounce off in all directions. This is called random motion. In 2 substances, when mixed, particles bounce off in all directions when they collide. This mixing process is called diffusion. It's also the movement of particles without a force. The smallest particle that cannot be broken down by chemical means is called an atom. ;In some substances, particles are Just single atoms.For example the gas argon, mound in air, is made up of single argon atoms. ;In many substances, particles consist of 2 atoms Joined together. These are called molecules. ;In other substances, particles consist of atoms or groups of atoms that carry a charge. These particles are called ions. Solids liquids and gases Solid Properties: Definite shape and volume ; Normally hard and rigid Large force required to change shape High Density ; Incompressible Model: ; Closely packed ; Occupy minimum space Regular pattern ; Vibrate in fixed position Not free to move Liquid Properties: ; Definite volume but no shape.Not compressible Occur in clusters with molecules slightly fury Free to move about within a confined vessel WPAD W. Transmigrate crossover Demand: Pu. Researcher's www. PDFWatermarkRemover. Com to remove the watermark Gas Properties: No Fixed volume and no fixed shape ; Low density ; Compressible Very far apart ; Travel at high speed ; Independent and random motions Negligible forces of attraction between them Diffusion in Gases Gases diffuse in different rates. Those rates depend on their factors: 1. Mass of the particles The lower the mass of its particles the faster a gas will diffuse. Why?Because the lighter the molecules†¦ He faster it will travel (obviously†¦ ) 2. The temperature The higher the temperature, the faster a gas will diffuse. Why? Because particles gain energy as they are heated Mixtures, Solutions, and Solve nts Mixture: Contains more the one substance. They are Just mixed together and not chemically combined. Example: Sand and water. Solution: It is when a solute and a solvent mix. The solute dissolves in the solvent making a solution. Example: sugar (solute) dissolves in water (solvent) making a solution of sugar and water. The solubility of every substance is different.To help a solute dissolve you could: ; Stir it Rise the temperature If you add excess amount of sugar in a small amount of water†¦ It won't dissolve as there is no space for it. The solution becomes saturated. Solvent: A substance that allows solutes to dissolve in Example: Water, Ethanol Pure substances and impurities A pure substance is a substance that has no particles of any other substance mixed with it. An unwanted substance, mixed with a wanted substance, is called an impurity. To check if a substance is pure, you have to check its melting and boiling points.A pure substance has a definite, sharp, melting p oint. When a substance is impure, the letting point falls and its boiling point rises. So the more impurity present, the wider and bigger the change in melting and boiling point. Separation methods: Filter – -? Solid from liquid Centrifuge -? Solid from liquid Evaporation -? Solid from its solution Crystallization Solid from its solution Distillation -? Solvent from a solution Fractional distillation Liquid from each other Chromatography solution Separation methods – Different substances from a 1.Filtering Example: A mixture of chalk and water†¦ 1. A filter paper is placed in a funnel, the funnel placed on a flask. 2. The mixture is poured on the filter paper. The chalk (the residue) will remain in the filter paper and the water (the filtrate) will fall down in the flask. 2. Centrifuging This method is used to separate small amounts of solid and liquid. Inside a centrifuge (it's a machine), test tubes are spun very fast so the solid gets flung to the bottom. 3. Ev aporation This method is used to separate a solution in which the solid is dissolved in the liquid. . The solution is heated so that the liquid evaporates and the solid remains in the bottom of the evaporating dish. 4. Crystallization This method is similar to evaporation but here the solid forms crystals then the rascals are left to dry. Separating a mixture of two solids 1. This can be done by dissolving one in an appropriate solvent. 2. Then filtering one and extracting the other from the solution by evaporation. 5. Simple distillation 1. The impure liquid is heated. 2. It boils, and steam rises into the condenser. 3. The impurities are left behind. . The condenser is cold so the steam condenses to the pure liquid and it drops out on the beaker. 6. Fractional distillation . The mixture is heated. The wanted substance boils and evaporates 2. (some of the unwanted liquid will evaporate too) and rises up the column. 3. The substance will condense on the beads in the column causing t hem to heat. 4. When the beads reach a certain temperature when the wanted liquid wont condense anymore (That's the boiling point) it will rise while the unwanted liquid will condense and drop.The wanted liquid will make its way through the condenser where it will condense and drop down in the beaker. 7. Chromatography This method is used to separate a mixture of substances. For example you can use it to find how many colored substances there are in black ink. Steps: 1. Drop the black ink on to the center off filter paper and allow it to dry. 2. Drop water on to the ink spot, one drop at a time. 3. Suppose there are three rings: yellow, red and blue. This shows the ink contains 3 colored substances. The substances travel across the paper at different rates.That's why they separate into rings. The filter paper showing the separate substances is called a chromatogram. This method works because different substances travel at different speeds because they have different levels of attrac tion to it. Uses of chromatography: Separate mixtures of substances ; Purify a substance by separating the impurities from it ; Unit 2: The Atom Identify a substance Atoms are the smallest particles. Each atom consists of a nucleus and a cloud of particles called electrons that whiz around the nucleus. An element is a substance that contains only one kind of atom.The periodic table is the â€Å"map/address book† for elements where each element is given a symbol (E. G. K for potassium). The group of elements that have similar properties are put in a numbered column. For example, if you know how one element in group 1 behaves, you can easily guess how the others in the same group will behave. The rows are called periods. The gig-gag line separates metals from non-metals, with the non-metals on the right. So most elements are metals. A compound contains atoms of different elements Joined together where the atoms are chemically combined.For example carbon dioxide is a compound of carbon and oxygen (1 carbon and 2 oxygen molecules). The symbol for compound is made from the symbols of the elements in it. So the formula for carbon dioxide is CO. Isotopes and Radioactivity You can identify an atom by the number of protons in it. For example, only sodium atoms have 11 protons. Isotopes are atoms of the same element, with different numbers of neutrons. Some isotopes are radioactive. That means its nucleus is unstable, sooner or later the toms breaks down or decays, giving out radiation in the form of rays and tiny particles, as well as large amount of energy.Like carbon-14, a number of other elements have radioisotopes that occur naturally and eventually decays. But the other two isotopes of carbon (like most natural isotopes) are non-radioactive. You can know when radioisotopes decay by looking at there half life. Radiation affects humans as it may causes them radiation sickness but radiation also has some uses. Uses of radiation: 1. Check for leaks in pipes (in dustry) This is done by adding a radioisotope to the oil or gas. At a leak, the radiation is detected using an instrument. Radioisotopes used in this way are called tracers. 2. N cancer treatment (Medical) Radioisotopes can cause cancer but yet also can cure it. Using radiotherapy the radioisotope will decay and give out rays that can kill cancer cells. These rays will be aimed exactly at the cancer cells. 3. To find the age of old remains A tiny percentage of a living thing contains carbon-14 atoms. When living thing dies it no longer takes in new carbon atoms. But existing carbon-14 atom decay over time – we can measure the faint radiation from them. How electrons are arranged The electrons in an atom circle fast around the nucleus, at different levels from it.These energy levels are caller electron shells. The further the shell is from the nucleus, the higher the energy level. Each shell can hold a limited number of electrons. First shell can hold up to 2 electrons Second shell can hold up to 8 electrons The third shell can also hold up to 8 electrons Electronic configuration means the arrangement of electrons in an atom. Argon has the electronic configuration : 2,8,8 Magnesium has the electronic configuration : 2,8,2 Important points: ; The shells fill in order, from lowest energy level to highest energy levelAll the elements in a group have the same number of electrons in their outer shells. These are called Valence electrons. ; The group number is the same number of outer shell electrons ; The period number shows how many shells there are. ; If an element posses a full outer shell, the element become enervative Unit 3: Atoms combining Most elements form compounds because they want a full outer shell and to achieve that they must react with other atoms. For example, sodium has Just one electron in its outer shell.It can obtain a full outer shell by losing this electron to anther atoms and by that it becomes a sodium ion. Now because sodium lost a e lectron†¦ It now has 10 electrons but 11 protons†¦ So it has a 1 positive charge. An ion is a charged particle. It is charged because it has an unequal number of protons and electrons. The ionic bond Sodium and chlorine react together; sodium gives its electron to chlorine. Now both elements have a full outer shell, but with a charge. Now they are ions. Sodium now has 10 electrons but 11 protons so it has a positive charge.Chlorine now has 18 electrons but 17 protons so it has a negative charge. The two ions have opposite charges, so they attract each other. The force of attraction between them is strong. It is called an ionic bond. When sodium reacts with chlorine, billions and billions of sodium and chlorine ions form and they attract each other. But the ions don't stay in pairs. They cluster together so that each ion is surrounded by 6 ions of opposite charges. The pattern grows until a giant structure of ions is formed. The overall charge of the structure is O since 1 positive charge and 1 negative charge neutralize each other.The ionic bonding is only between metals and non-metals. Important notes: Hydrogen and the metals form positive ions Non-metals form negative ions, and their names end in -did ; Group 4 and 5 do to usually form ions because they would have to lose or gain several electrons and that takes too much energy ; Group O elements do not form ions; they already have full outer shells ; Some of the transition metals form more than one ion. Some ions can be formed from groups of Joined atoms. These are called compound ions. Properties of ionic compound 1.Ionic compounds have high melting and boiling points. This is because ionic bonds are very strong, so it takes a lot of heat energy to break up the lattice. 2. Ionic compounds are usually soluble in water. The water molecules can attract the ions away from the lattice. The ions can then move freely, surrounded by water molecules. 3. Ionic compounds can conduct electricity when they ar e melted or dissolved. When melted the lattice breaks up and the ions are free to move. Since they are charged, this means they can conduct electricity.The solutions of ionic compounds conduct electricity too because they are also free to move. The covalent bond Giving and losing an electron is not the only way to gain full outer shells since atoms can also share electrons. Covalent bonding is for non-metals only since only non-metals need to gain electrons. A molecule is a group of atoms held together by covalent bonds. When a pair of electrons is shared, it is called a single covalent bond, or Just single bond. When 2 pairs of electrons are shared, it is called a double covalent bond, or Just double bond.When 3 pairs of electrons are shared, it is called a triple covalent bond, or Just triple Covalent compounds A covalent compound is when atoms of different elements share electrons with each other. The molecules in a covalent compound isn't flat because each electron repel each ot her and try to get as far apart from each other. Molecular substances Most molecular substances are gases or liquids at room temperature. Molecular lids are held in a lattice but the forces between the molecules are weak. All molecular solids have similar structure.The molecules are held in regular pattern in a lattice. So the solids are crystalline. When you cool down a molecular liquid or gas the molecules lose energy so they start moving slowly and at the freezing point, they form a lattice (a good example would be ice) Properties of covalent bonding 1. Covalent compounds have low melting and boiling point This is because the forces between the molecules are weak. 2. They do not conduct electricity This is because molecules are not charged, so they cannot conduct, even when melted
