Evaluating Human Resource Management Essay Example | Topics and Well Written Essays - 2000 words - 1

Evaluating Human Resource Management - Essay Example After hiring these employees, it is their role to improve the performance of the staff and make sure that their contribution to the company gets larger and larger as they prolong their stay in the entity. Moreover, the management should also make sure that the employees they hired abide by the rules set by the company and to know the demands of these employees to avoid conflict against the company. Aside from employee selection and hiring, the human resource management is also responsible for the benefits and compensation each and every employee is entitled of. The management has to make sure that they meet the needs of these personnel to avoid labour unions forming that ought to go against the company policy. According to McNamara [2005], small scale businesses do not usually have their own human resource management because they cannot afford to acquire either part-time or full-time help from independent contractors. These small scale businesses do the function and activities of the human resource management on their own. The managers of these small businesses have to monitor the employees they hired and make sure they follow the rules and regulations. Although they are small-sized businesses, it is also their responsibility to provide employee’s manuals to their staff to let them know the rules and policies and the rights that they are entitled of. In addition to what McNamara [2005] said, the human resource management have undergone some big changes over the past 20 to 30 years. Before, the human resource department was even called personnel department, which is in charge of just the employee paper works, hiring and giving salaries to personnel. However, drastic changes occurred which improved and gave a bigger responsibility to the management. This big change include staffing, personnel management, giving out extensive training to the

Kmarts Downfall Essay Example | Topics and Well Written Essays - 750 words

Kmarts Downfall - Essay Example The competition model established by Porter is an analytical tool for studying industry behavior and corporate strategies. It is derived from industrial organization economics and includes five forces. These forces, in turn, determine the level of competition, and thus that profitability of a market. These five forces comprise of substitutes, competitors, new entering firms, bargaining power of suppliers and customers. The facts of this case study reveal that Kmart was facing intense competition from Wal-mart and Target. Wal-Mart initiated the movement of every day low prices, which was a more worthy substitute for products in Kmart. In addition, Wal-Mart utilized information technology to keep a record of sales in all of their stores and for ordering stocks of fast moving items. Wal-mart heavily invested in information technology by installing new registers with barcode scanners in every store during the 1970s and early 1980s, which fed the sales data into the back-end computers. This information, in turn, assisted them in planning future strategies, deciding which products reap more profit. Thus, they gained a competitive advantage. By 1983, Wal-Mart was able to receive goods for only two cents whereas Kmart had to pay five cents per dollar for getting goods to stores. This meant that Wal-Mart was in a position to sell products at a price three percent lesser in contrast to Kmart. Then, another c ompetitor Target began a new campaign in which they depicted themselves as a low-cost source of quality and style mart. They focused on merchandising. These attractive schemes took away Kmart’s market share. This demonstrates that Kmart was under intense pressure of substitutes, competitors, and lost customers. In 1987, Kmart undertook investments worth 1 million to modernize their systems.  

Viola Assignment Example | Topics and Well Written Essays - 250 words

Viola - Assignment Example In describing her love for Orsino, she states that â€Å"†¦ she sat like patience on a monument. Smiling at grief. Was not this love indeed?† (II. iv. 60). This shows how sincere her love for Orsino was. She claimed that her state was desperate for her master’s love. Viola is also used to illustrate how violent and frustrating love can be. Although Viola, who disguises as Cesario, is in love with her master, she remains loyal to him. This makes Olivia, the Orsino’s lover, like her for her boldness, thinking she is a man. This makes Orsino accuse Viola (Cesario), of taking Oliviia away from him. This leads to a chaotic confrontation between Orsino and Viola. Shakespeare is thus able to portray the good and bad side of love through Viola. Finally, because of her disguise, Viola is able to influence other characters in the play. She is used to highlight the kind of love men have for women and vice versa. For instance, the fact that she acts as a man, she is able to reveal to the audience the kind of love that exists between Olivia and Orsino, and the feelings they have for one

Myoglobin In The Utilization Of Oxygen In Animals Biology Essay

Myoglobin In The Utilization Of Oxygen In Animals Biology Essay Myoglobin is an oxygen-binding globular protein which is vital in facilitating the acquisition and utilization of oxygen in animals. Myoglobin was isolated and purified from ground water buffalo extract. The Myoglobin was isolated by cation-exchange chromatography, and concentration of Myoglobin is measured by spectrophotometry. Total concentration of protein was determined by performing Bradford protein assay. Iron analysis was performed by atomic absorption spectrophotometry (AAS). Molecular weight of Myoglobin was determined by running SDS-PAGE. A total amount of 144 ug Myoglobin was purified by the cation-exchange chromatography with a relative purity of 25.9%. The concentration of the purified Myoglobin was determined to be 0.072 ug/uL. The molecular weight of Myoglobin was determined to be 18204 Da And 0.423 mg of iron were detected in the acid digested extract Introduction Myoglobin is a globular protein which contains a single polypeptide chain of about 153 amino acids and an iron-porphyrin complex, or the heme group (3). And it has a molecular weight of 16700 Da and 153 amino acids (4). The non-covalently bound heme group, which resides in the hydrophobic interior of the native globin chain, is able to unfold under acidic condition and consequently weakens the interaction between the heme group and the globin (5). Myoglobin is an oxygen-transport protein which can be found in muscle tissues of all mammles. Myoglobin is critical in mammalian cell in that it is responsible for storage and distribution of oxygen, and possibly carrying energy (4). Diving animals such as seals and whales have excessive amount of Myoglobin that help them travel undersea by storing and transport oxygen (9). It plays a significant role in the physiological function of heart and skeletal muscle (2). Elevated consumption of oxygen during exercise necessitates the production of myoglobin in red muscle and heart cells, and the transportation of oxygen by myoglobin from the sarcolemma to the mitochondria in vertebrate heart and red muscle cells. (1) Spectrophotometry studies the interaction of electromagnetic radiation with molecules, atoms and ions (10). It can shed light on the physical and chemical properties by measuring the emission or absorption of electromagnetic radiation (10). Besides, it is also used to identify biomolecules from their individual absorption spectrum. In the meantime, spectrophotomoetry can quantitatively measure the concentration of molecules in solution According to the Beer-Lambert law, the fraction of incident light absorbed by a solution at a given wavelength is indicative of the concentration of the absorbing species (10) . Tryptophan and tyrosine can absorb ultraviolet light, which accounts for the characteristic strong absorbance of light at wavelength of 280 nm by most proteins (9). Atomic absorption spectroscopy (AAS)can be used to determine the identity and concentration of chemical elements in the gaseous state by measuring the light radiation absorbed by the elements (10). Ion-exchange chromatography is a technique for separating biomolecules capable of being involved in electrostatic interactions (10). Molecules can be separated based on their sign and magnitude of net charge at a given pH and formation of electrostatic linkages between thee resin and the protein of interest (9). Ion exchange separations take place in columns packed with an iron-exchange resin (10). Resins with bound anionic groups are cation exchanges whereas those with bound cationic groups are anion exchangers (9). Selection of ion exchange resin depends on what is to be purified, the pH to be used in the column, and the strength of the functional group (10). Electrophoresis is the separation of proteins based on the motion of the charged proteins under the influence of an electric field (9). The migration of the protein depends on its shape, size, charge and chemical composition (10). An electrophoretic method, polyacrylamide gel electrophoresis (SDS-PAGE) can be used to estimate the purity and determine the molecular weight of the protein (9). Treatment of the protein by the ionic detergent sodium dodecyl sulfate (SDS) can give it a uniform net charge, and protein can then be separated based solely on its mass (10). In this experiment, Myoglobin is extracted and purified by cation-exchange chromatography from ground water buffalo using Beffer A (20 nM, pH 5.6, KH2PO4) and Buffer B (20mM, Tris buffer, pH 7.5). Absorbance of the eluent fractions is measured at 280nm and 417nm. Total amount of protein and the concentration of Myoglobin are determined using Bradford assay from BSA protein. Molecular weight of Myoglobin was determined by performing SDS-PAGE. Iron content in the acid digested extract is measured by atomic absorption spectrophotometry (AAS). A total amount of 144 ug Myoglobin was purified by the cation-exchange chromatography with a relative purity of 25.9%. The molecular weight of Myoglobin was determined to be 18204 Da. 0.757 mmol of iron and 39.5 nmol of myoglobin were detected in the acid digested extract, with a ration of 20:1. Results A total of five samples were collected from a solution of 10.02g thawed ground buffalo mixed with 20.0mL, 20mM, pH 5.6, KH2PO4 (Buffer A): 1.0 mL of crude extract (sample C), 1.0 mL of filtered extract (sample D), 2.0 mL of Buffer A sample solution (sample A), 2.0 mL Buffer B sample solution (sample B) and 5.0 mL acid digested extract solution. Chromatogram for the purification of myoglobin carried out by cation-exchange chromatography shows a large peak from fraction number 5 to fraction number 12. (Figure 1). The figure also indicates another peak at fraction number 23, with smaller peaks at fraction number 19 and fraction number 25 (Figure 1). Fraction number 23 has the highest 417 nm/ 280 nm (3.766) and the highest absorbance 90.278) at 280 nm (Figure 1). Discussion When myoglobin was separated by cation-exchange chromatograph, purity of the myoglobin in the eluent fractions collected at specific volumes was examined by spectroscopy. Absorbance of Myoglobin, specifically, was measured at 417 nm and other proteins was measured at 280 nm, due to the presence of Tyrosine and Tryptophan Most proteins absorbs at a wavelength of 280 nm (10). Phophyrin has an absorbance spectrum of 414nm to 418 nm, and intensity and wavelength of the absorption can be influenced by the peripheral substituents on the porphryin and the protonation state of the nitrogen atoms (6). Sincemyoglobin consists of a iron-containing heme prosthetic group with an iron-contained porphyrin ring (9), it can absorb at a wavelength of 417. Myoglobin has a PI value of 7, so it will have a net positive charge when pH is below its PI and a net negative charge when pH is above its PI. When myoglobin is positively charged when buffer A (pH=5.6) is used to wash the column, it binds to a column containing negatively charged beads in cation-exchange chromatography. The positively charged Myoglobin can then be eluted by washing the column with buffers having higher pH value than 7 (Buffer B, pH= 7.5). Raising the pH of the mobiles phase buffer renders the Myoglobin less protonated and thus negatively charged. As a result, the Myoglobin is not be able to form an ionic interaction with the negatively charged stationary phase and then elutes from the column (10). 144 ug Myoglobin was recovered form the column, which accounts for 10.7% of the myoglobin that was loaded onto the column. Loss of Myoglobin could be attributed to diffusion spreading of Myoglobin and other contaminant proteins within the mobile phase, as a result of the increase in time length (9). Recovery of myoglobin can be improved by using narrow columns, longer column (7). The molecular weight of Myoglobin (18204 Da) obtained from the SDS-PAGE was similar to the literature value, 16700 Da (4), which indicated that the purified protein in the Buffer B sample was Myoglobin. The clear band generated from Lane B migrated the same distance as the band from the Myoglobin standard, which further confirms that the purified protein was Myoglobin (Figure 3). The stoichiometric relationship between iron and hemoglobin is 20:1 instead of 1:1 according to the fact each molecule of Myoglobin has only one molecule of ion. The excessive amount of Fe might be present in oxygen-carrying protein such as hemoglobin, which contains four heme prosthetic groups. Electron carriers in the mitochondrial respiratory chain have Fe incorporated in their prosthetic group, and examples of them include cytochomr c, ubiquinone and cytochrome oxidase. Besides, another hemeprotein, ferritin might also be present in the protein sample. Hemeprotein functions to stores and release iron atoms in biologically available form for use in heme and nonheme proteins and biochemical reactions (8). In conclusion, a ratio of 1:20 for Myoglobin and iron was obtained from the ground water buffalo. 144 ug Myoglobin was purified from the filtered extract with a relative purity of 25.9%. According to SDS-PAGE, the molecular weight of Myoglobin was determined to be 18402 Da.

MARY FLANNERY OCONNOR :: essays research papers

MARY FLANNERY O'CONNOR Flannery O'Connor was a Southern writer especially noted for 32 incisive short stories before a tragic death at the age of 39. Mary Flannery O'Connor was born March 25, 1925 in Savannah, Georgia, the only child of Francis and Regina O'Connor. The family lived on Lafayette Square at 207 East Charlton Street in Savannah, adjacent to the Cathedral of St. John the Baptist, where Mary Flannery was baptized into the Catholic faith on April 12, 1925. She attended school at St. Vincent's grammar school, taught by the Sisters of Mercy from Ireland. She received national media attention at the age of five when she trained a chicken to walk backwards. The summers were often spent visiting her mother's family, the Clines, in Milledgeville, Georgia. Because of financial difficulties with his real estate business, her father, who had developed health problems as well, took a federal job in Atlanta in 1938, when Mary Flannery was 13. However, settling in Atlanta proved difficult for the family, and Mary Flannery and her mother Regina Cline O'Connor moved to the mother's family home in Milledgeville in fall of the same year. Her father's health continued to decline, and it was not until shortly before his death on February 1, 1941 that he was diagnosed with systemic lupus erythematosis, the same disease that would claim Flannery. Following graduation from Peabody High School and the Georgia State College for Women in Milledgeville, she began attending the State University of Iowa, where she began her writing career and introduced herself as Flannery. While in Iowa City, she attended Mass daily at St. Mary's Church; throughout her life, she remained true to her Catholic faith. During graduate school, her short story The Geranium was accepted for publication by Accent in 1946. She submitted her thesis in 1947, entitled The Geranium: a Collection of [Six] Short Stories, and received her Masters of Fine Arts degree on June 1, 1947. Flannery O'Connor's writings offer deep insight on the fallen nature of mankind through original sin, but redemption through the grace of Jesus Christ. Flannery O'Connor's first novel, Wise Blood, published in 1952, achieved only a modest reception. However, she received critical acclaim and popular success with the 1955 publication of A Good Man is Hard to Find, a collection of 10 short stories, the first story bearing the same name. A second novel, The Violent Bear it Away, was published in 1960.
