Construct Development and Scale Creation Essay - 1465 Words

Part I: Construct Development and Scale Creation Choose a construct you would like to measure. I picked self-confidence. According to Brown (2004) self confidence is defined as ones ability to rely on themselves, to assert oneself socially, regarding what one thinks and possessing the skills to work independently, based on ones learning from personal experience and the ability to make use of prior knowledge. Self confidence measures include self efficacy, self esteem, knowledge and ability to work out problem situations and make informed and successful decisions, without relying on other individuals.

Therefore, it is reasonable to assume that confidence in ones ability to use the Internet positively influences the willingness to adopt and use SNS, because internal beliefs are associated with actual behavior. Nothing is more important in life than having positive self-esteem and a positive outlook on life. With positive self-esteem, a person can accomplish just about anything they put their mind to. Developing self-esteem starts from the day a baby is born and continues throughout their life, but unfortunately, this development is not always complete for some by the time they are adults. If we have low confidence in ourselves and our ability to succeed, it’s time to take another look at how we can build confidence. First of all, it’s important to recognize and believe that positive self esteem cultivates success. The greater our self esteem, the better equipped we are to deal with life’s daily challenges and stressors. Positive self esteem enables us to handle problems and bounce back from them quicker. Base on the self confidence survey, we can realize that a person’s level of self confidence recognizes that she/he is responsible for the decisions that she/he makes. If a person believes they can achieve something, then they will. But low esteem will pull them down and it will beShow MoreRelatedEssay on Construct Development, Scale Creation, and Process Analysis1202 Words   |  5 PagesConstruct Development, Scale Creation, and Process Analysis PSYCH 525 University of Phoenix Part 1: Construct Development and Scale Creation The construct that will be measure in this paper will be arrogance versus confidence.

Life and Work of Maud Lewis, Canadian Folk Artist

Maud Lewis (March 7, 1903 – July 30,  1970) was a 20th-century Canadian folk artist. With a focus on subjects in nature and ordinary life and a folk style of painting, she became one of the best-known artists in Canadian history. Fast Facts: Maud Lewis Occupation: Painter and folk artistBorn: March 7, 1903 in South Ohio, Nova Scotia, CanadaDied: July 30, 1970 in Digby, Nova Scotia, CanadaParents: John and Agnes DowleySpouse: Everett LewisKey Accomplishments: Despite physical limitations and poverty, Lewis became a beloved folk artist, known for her brightly colored paintings of animals, flowers, and outdoor scenes.Quote:  Ã¢â‚¬Å"I paint all from memory, I don’t copy much. Because I don’t go nowhere, I just make my own designs up.† Early Life Born Maud Kathleen Dowley in South Ohio,  Nova Scotia, Lewis was the only daughter of John and Agnes Dowley. She had one brother, Charles, who was older than her. Even as a child, she suffered from rheumatoid arthritis, which limited her movements, even down to her hands. Despite this, she began making art at an early age under the tutelage of her mother, who taught her to paint watercolor Christmas cards, which she then sold. Maud dealt with multiple physical disabilities that left her hunched over. At the age of fourteen, she dropped out of school for unknown reasons, although it is possible that the bullying of her classmates (due to her visible birth defects) was at least partially at fault. Family and Marriage As a young woman, Maud became romantically involved with a man named Emery Allen, but they never married. In 1928, however, she gave birth to their daughter, Catherine. Allen abandoned Maud and their daughter, and they instead continued to live with her parents. Because Maud had no income and no means to support her child, a court required Catherine to be placed up for adoption. Later in life, an adult Catherine (now married with a family of her own and still living in Nova Scotia) attempted to get in touch with her mother; she was never successful in her attempts. Maud’s parents died within two years of each other: her father in 1935 and her mother in 1937. Her brother Charles inherited everything, and while he allowed his sister to live with him for a short while, she soon moved to Digby, Nova Scotia, to live with her aunt. In late 1937, Maud answered an advertisement placed by Everett Lewis, a fish peddler from Marshalltown, who was seeking a live-in housekeeper. While she was unable to perform her job well, due to the advancement of her arthritis, Maud and Everett married in January 1938. Painting Every Surface The painted interior of Maud Lewis home, as it is preserved in the Art Gallery of Nova Scotia.   Courtesy of the Art Gallery of Nova Scotia. The Lewises lived mostly in poverty, but Everett did encourage his wife’s painting – especially once he realized they could make a small profit. He procured  painting supplies  for her, and she then accompanied him on selling trips, starting with small cards like those she had painted as a child and eventually expanding to other, larger media. She even painted nearly every suitable surface in their small home, from typical sites such as walls to more unconventional ones (including their stove). Because canvas was difficult to come by (and expensive), Maud worked on beaver boards (made of compressed wood fibers) and Masonite, among other things. These smaller items, early in her career or for personal use, were full of bright colors and designs of flowers, birds, and leaves. This aesthetic would carry over into her later work as well. Early Sales Maud Lewis,  White Cat (2), 1960s, oil on pulpboard, 31.1 x 33.8 cm. Collection of the Art Gallery of Nova Scotia, gift of Johanna Hickey, Vancouver, BC, 2006.   Maud’s paintings, throughout her career, focused on scenes and items out of her own life, experiences, and surroundings. Animals appeared frequently, mostly domestic or farm animals such as cows, oxen, cats, and birds. She also portrayed outdoor scenes: boats on the water, winter sleigh or skating scenes, and similar moments of ordinary life, often with a playful and cheerful tone. The greeting cards of her youth came back again, this time as inspiration for her later paintings. Bright, pure colors are a hallmark of her paintings; in fact, she was known to never blend colors, but only use the oils as they came originally in their tubes. Most of her paintings are quite small, not exceeding eight by ten inches. This is mostly due to the constraints of her arthritis: she could only paint as far as she could move her arms, which was increasingly limited. However, there are a few of her paintings that are larger than that, and she was commissioned to paint a large set of shutters by American cottage owners in the early 1940s. Gaining Wider Attention Maud Lewis,  Fall Scene with Deer,  c. 1950, oil on pulpboard, 29.5 x 34.9 cm. Collection of the Art Gallery of Nova Scotia, purchase 1974. During her lifetime, Maud’s paintings did not sell for large amounts. By the late 1940s, tourists had begun to stop at the Lewises’ home to purchase her paintings, but they rarely sold for more than a few dollars. In fact, they wouldn’t sell for even close to ten dollars until the final years of her life. The Lewises continued to live a meager existence, with Everett taking on the lion’s share of work around the house as Maud’s arthritis continued to degenerate her mobility. Despite the attention of the occasional tourist, Lewis’s work remained fairly obscure for the majority of her life. All that changed in 1964, when the Toronto-based national newspaper  Star Weekly  wrote an article about her as a folk artist and brought her to the attention of audience across Canada, who quickly embraced her and her work. The attention only increased the following year, when the broadcasting network CBC featured her on its program  Telescope, which featured Canadians of varying degrees of notoriety who had made a difference in some way. In the final years of her life and following these major public mentions, Lewis was on the receiving end of commissions from a wide array of important figures – most notably, American president  Richard Nixon  commissioned a pair of paintings from her. She never left her home in Nova Scotia and was unable to keep up with the demand for artwork. Death and Legacy Maud Lewis,  Maud Lewis House, mixed media, 4.1 x 3.8 m. Collection of the Art Gallery of Nova Scotia, purchased by the Province of Nova Scotia, 1984.   Maud’s health continued to deteriorate, and in the late 1960s, she spent most of her shuttling between painting in her home and visiting the hospital for treatment. Her declining health was exacerbated by the wood smoke of their home and the constant exposure to paint fumes without proper ventilation, and the lung issues this caused left her susceptible to pneumonia. She died on July 30, 1970, after battling pneumonia. After her death, demand for her paintings skyrocketed, as did the appearance of forgeries. Several paintings purported to be Maud’s were eventually proven to be fakes; many are suspected to be the handiwork of her husband Everett in an attempt to continue cashing in on her prominence. In recent years, Maud’s paintings have only grown more valuable. She has become something of a folk hero in her home province of Nova Scotia, which has long embraced artists with authenticity and unusual styles, and in Canada as a whole. In the 21st  century, her paintings have sold at prices well into five figures. After Everett’s death in 1979, the Lewises’ house began to fall into disrepair. In 1984, it was purchased by the Province of Nova Scotia, and the Art Gallery of Nova Scotia took over the care and preservation of the house. It now dwells in the gallery as part of a permanent exhibit of Maud’s works. Her paintings have made her a folk hero among the Canadian art community, and the bright joyfulness of her style, combined with the humble, often harsh realities of her life, have resonated with patrons and fans worldwide.

Aspirin Sample free essay sample

Lab Report Introduction This lab has the following two concepts: synthesis of acetylsalicylic acid and analysis of acetylsalicylic acid. Synthesis is a purposeful execution of chemical reactions to obtain a product. This concept is used in the first part of the lab; when we have to produce crystals of aspirin. Analysis is the separation, identification, and quantification of the chemical components of natural and artificial materials. This concept is used throughout the lab when we are analyzing different reactions that are happing during the duration of the lab. The goal of this lab is to synthesize a sample of acetylsalicylic acid, otherwise known as aspirin. This is the most important goal of the lab. This, however, has side goals that go along with the main one. One is finding the percent yield of the synthesis. Another is measuring the melting point of the aspirin sample, which will in turn indicate the purity of the sample. The last is conducting a colorimetric analysis on the aspirin sample. The educational goals of this lab are to find the structural formulas for salicylic acid, acetic anhydride, and aspirin and to use these structural formulas to construct a reaction equation by describing the synthesis of aspirin. In addition, you have to be able to use your percent purity calculations to determine the percent yield of your synthesis of aspirin. Methods and Materials Part I: Synthesis Aspirin Goggles were obtained and put on before entering the lab area. 2. 0 grams of salicylic acid should be measured and placed into a 125 mL Erlenmeyer flask. 5. 0 mL of acetic anhydride and 5 drops of 85% phosphoric acid was added to the Erlenmeyer flask. Drops of distilled water were added to rinse down bits of solids that were on inner wall of the flask. Mixture was heated on the hot plate for fifth-teen minutes, at 75 degrees Celsius. Two mL of distilled water was added 10 minutes into heating. Buchner funnel and filter were set up for the filtration process. Reaction was completed and 20 mL of distilled water was added to the flask. Flask was cooled for 5 minutes in an ice bath. Aspirin crystals were formed after cooling of the flask. Contents were transferred into Buchner funnel assembly. The mixture was filtered with the assistance of the vacuum. When all liquid had drained out, suction was stopped. Then 5 mL of cold distilled water was added and after 15 seconds the vacuum was turned back on. This procedure was repeated two more times in the same manner. Aspirin crystals were stored in a safe place for purity test. Part II: Test the Melting Temperature of an Aspirin Sample Temperature Probe was connected to the Lab Quest deceive and new file was opened. About 0. 2 grams of aspirin was placed into the mortar. The pestle was used to pulverize the aspirin inside the mortar. A capillary tube was obtained. Aspirin was packed to the 1 cm marked inside the capillary tube. Capillary tube was fastened to the temperature probe by a rubber band. A mineral bath was heated up on the hot plate. Capillary tube-Temperature Probe was immersed inside mineral oil bath. The melting point was recorded as precise as possible. A second test was conducted with a new sample of aspirin in a new capillary tube. Part III: Test the Colorimetric Absorbance of an Aspirin Sample Next, about 0. 20 g of salicylic acid was recorded. It was then transferred to a 250mL beaker and 10mL of 95% ethanol was added and swirled until it was all dissolved. 150mL of distilled water was then added and mixed with the solution in the beaker. The contents were then placed into a 250mL volumetric flask. Distilled water was added until it hit the 250mL mark on the flask. The molar concentration was calculated and recorded. Next, four standard solutions of varying concentrations were created. 100mL of the standard solution was prepared with 10mL of the previously made solution into a volumetric flask. 0. 025 M Fe(NO3)3 solution was added to make precisely 100mL. The first trial used 10. 0mL salicylic acid and 0mL water, the second used 7. 5mL salicylic acid and 2. 5mL water, the third used 5. 0mL salicylic acid and 5. 0mL water, and the fourth used 2. 5mL salicylic acid and 7. 5 mL water. Now the calorimeter was used to collect data. The cuvette was removed and the water inside of it was removed and it was rinsed out twice. Next the device was calibrated. Afterwards, use each of the four solutions, separately, and place it in the cuvette to determine the molar concentration. This is repeated until all needed concentrations are found. Next the graph of absorbance vs. concentration was viewed on the LabQuest. Each point on the graph shows the concentration as well as absorbance. The results were recorded. â€Å"Curve Fit† was selected from the Analyze menu. Linear as the Fit Equation was selected and the equation was recorded. Next, the aspirin sample was prepared for testing. 0. 40g of the sample was massed and transferred to the 250mL beaker. 10mL of 95% ethanol and 150mL distilled water was added and mixed into the solution. This solution was put from the 250mL volumetric flask to a 100mL volumetric flask. 0. 025 M Fe(NO3)3 was added until there was precisely 100mL in the flask. Next the absorbance of the aspirin was recorded using the calorimeter. The cuvette was filled 3/4 with the sample. It was then placed into the device and measured. This was repeated two times. All of the materials were then cleaned up, put away, and discarded as directed Results Part I: Synthesis of Aspirin Sample Trial 1 Mass of Salicylic acid used (g) Volume of acetic anhydride used (mL) Mass of acetic anhydride used (vol *1. 08 g/ml) Mass of aspirin synthesized (g) Trial 1 Mass of Salicylic acid used (g) Volume of acetic anhydride used (mL) Mass of acetic anhydride used (vol *1. 08 g/ml) Mass of aspirin synthesized (g) Part II: Melting Temperature Data Trial 1 Melting Temperature (Celsius ) Trial 1 Melting Temperature (Celsius ) Part III Salicylic Acid Standard Stock Solution Sample Initial mass of salicylic acid Moles of salicylic acid (mol) Intial molarity of salicylic acid (M) Initial mass of salicylic acid Moles of salicylic acid (mol) Intial molarity of salicylic acid (M) Part III Beer’s Law Data for Salicylic Acid for Sample Standard Solutions Trial Concentration (M)Absorbance 1 2 3 4 Trial Concentration (M)Absorbance 1 2 3 4 Best-fit line equation or the salicylic acid standards Best-fit line equation or the salicylic acid standards Test of the Purity of the Synthesize Sample Aspirin Initial mass of aspirin sample (g) Absorbance of aspirin sample Moles of salicylic acid in aspirin sample (mol) Mass of salicylic acid in aspirin sample (g) Mass of aspirin in sample (g) Percent aspirin in sample (%) Initial mass of aspirin sample (g) Absorbance of aspirin sample Moles of salicylic acid in aspirin sample (mol) Mass of salicylic acid in aspirin sample (g) Mass of aspirin in sample (g) Percent aspirin in sample (%) Questions and Calculations 1.

Discussions My beginning question before I started this lab was â€Å"What will happen if you do not measure and record the absorbance of the treated aspirin sample within five minutes? † I did not get an answer to my question because I recorded and measured my aspirin way under the five minute period. If I did go over, however, I would think that my substance would become useless and I would have to start all over again. Also in the direction it says that this aspirin must be done quickly. Another question that came to my prior to starting the lab was â€Å"Does adding distilled water affect the overall purity of the substance? † In my case, yes adding distilled water does affect the overall purity of the aspirin. Why? That’s because throughout the lab I had to constantly add more distilled water. In part II when we had to but the crystals into the funnel, in my case the crystals were frozen to the bottom. So I had to keep adding water for it to come out and I had to add even more water to get out the crystals that were stuck on the side of the funnel. Although I followed the directions to the best of my ability, they were quite confusing which caused numerous amounts of errors. It was all going well until part II, which involved the capillary tube. This part was absolutely ridiculous because it was extremely difficult to get the beat up aspirin inside the tube. Once we finally got it filled and put it in the mineral oil bath, the rubber band melted before the aspirin; which made no sense. After many try however, we finally got it all to work in our favor and got a pretty good melting point. Another error that occurred in my lab due to the direction was in the preparation of the stock salicylic. The way it was written kept confusing me, so much that I took me five times to finally make the solution properly. It was not only a waste of material but also time. There were also case that were out of my reach. The first being the evacuating of the room because someone solution started to smoke up. Also, the unexpected fire drill that throw almost everybody off. In my opinion to avoid all of this, the lab should be split into two days. The first day being Part 1 and 2 because that took a little less than 2 hours. The next day only consisting of part 3 because it was extremely complicating. My overall performance in this lab was a little above average. It seemed that I had a good start because I got an amazing yield on my overall aspirin crystal. In my opinion if I could have somehow avoided all the errors that caused me to waste my time, the lab would have been a success. Conclusion In the end, this lab helped me understand some key concepts that I didn’t have a good understanding of before. This also helped me important laboratory procedures and techniques. I also learned a very important lesson; which was that you need to read the lab more than just once or else you will not be able to conduct it smoothly. Other than that, this lab was a very interesting type of learning experience and I hope we do many labs like this in the future.

Barriers in the Game of Volleyball-Free-Samples for Students

Question: Write an essay under exam conditions. In your essay, you must evaluate which level/s of Figueroas Framework created the greatest barriers to your opportunity to participate equitably in Volleyball (past), and which currently (present) impact on your involvement and improvement in the game. You must also recommend ways in which these barriers could have (past), and can now (present) be removed. Answer: Professor Peter Figuero has developed an important tool that helps in investigating the different issues that mainly remains based on the equity, access and equality in sports. This has been constructed over five levels that are cultural, structural, institutional, interpersonal and individual (Figueroa An, 2017). Each of the levels of the framework is seen to be connected with each other that in turn help in assessing the physical activities of individuals. The main purpose of the essay is to discuss mainly two important levels of the framework (interpersonal and individual) that had created significant barriers for my participation in the volleyball game. I will mainly conduct an evaluation about how these levels had affected my performance in the long run and the initiatives that I will take to overcome the barriers in the game of volleyball. One of the levels is the interpersonal level. This level is mainly seen to affect my behavior, my personal progress as well as my access to effective participation in the game (Mezzadri et al., 2017). This level will help to discuss how my relationships with my parents, peers, sport models, coaches and siblings had been influencing in my career and the sporting opportunities I had in volleyball. My families role is highly impacting as they are the agents who are directly associated with my attitudes, behaviors, access and participation. They provide resources like money, time, enthusiasm, courage and people skills that are very important for an individual like me who is progressing with volleyball game opportunity. I often used to fall on the ground while practicing as I had a poor balance and hurt myself several times. This made me bed-ridden for several days for which I had to miss volleyball classes in schools. I used to be weak initially and feared to lead the team. My coach used to treat me badly as I performed poorly and had no enthusiasm. My other teammates used to make fun of me when I used to fall while playing. This affected me mentally and emotionally resulting in poor self-esteem and lack of confidence. This delayed my entire sports career. Moreover, several stereotypes had affected me when I came to hear that such sports have no future by my friends who were not engaged with sports. At one time, I had succumbed to the societal pressures and got depressed and anxious. These societal pressures were acting as barriers. All these had cumulative effect on me both physically and mentally and I felt like leaving this obsession finally. Another level that I would discuss is the individual aspects that had affected my progress in volleyball. I cannot take up much stress at a time. Volleyball required me to practice the game in open sun that harmed my skin as well. As my immunity system was weak, I often used to fall sick and suffered from severe back pain, pain in limbs and arms and many others. Moreover, my skin was sensitive and so I developed skin problems. All these made me lose my enthusiasm on the game. My physical and mental weakness acted as barriers in my volleyball game. Researchers have stated that athletes should have zeal and enthusiasm to overcome all barriers that come in the way (Barron et al., 2018). I will not be blown away by the stereotypes of my friends and will stick to my aim. In order to develop my physical stamina, I will regularly exercise and will join a gymnasium after I get attain financial stability. Regular exercises increase physical stamina (Pedersen Saltin, 2015). Moreover, I will also undertake meditation and yoga sessions. These help individuals to overcome their anxious nature and will help them to calm down mentally (Saini Lahange, 2017). It will increase my concentration that will have better effect on my game. I have understood that self-esteem and self-confidence are the only ways that would help me overcome all the barriers. Therefore, I will try to be confident in the decisions I take and will handle all my life problems successfully. I will not let pressure destroy my zeal and will overcome all barriers not by esca ping from them but facing them with strength and vigor. Moreover, I will try my best to develop a team with my coach that will promote equity among team members irrespective of skills, gender, race and others. This will prevent any individuals from being bullied by others unlike the situations I faced. All these will increase my self-esteem and my performance will develop. Therefore, the framework had helped me two analyze two important levels and how it had helped me in shaping as a sports person. I will try my best to dedicate myself fully so that I can achieve success in my life. References: Barron, D.M., Alvarez, C.C., Kulkarni, S.
