GENETICS - Essay Example Myra was diagnosed with cancer at the age of 48, indicating that it is likely that her cancer was sporadic rather than inherited, however this does not rule out the possibility of the cancer being heritable. In contrast, her mother died from cancer at a ‘young’ age, which suggests the possibility that this was an inherited susceptibility. The fact that there is a chance that the susceptibility may have been inherited means that I would have raised the possibility of a referral with Myra on the basis of her family history alone. The presence of a defective gene, which can be passed from parent to child, results in the child having up to an 80% probability of getting cancer at some point in their lifetime . There are many benefits to genetic counselling, including an increased understanding of whether the disease is inherited and what the chances that offspring will inherit it are . Many different things are inherited genetically; a child may inherit his mother’s bl ue eyes, or his father’s nose shape as well as the susceptibility to a particular disease that is present on his father’s side of the family. ... Many people consider that a child is ‘more like his mother’ or ‘more like his father’ based on their physical appearance. However, while this is a common belief it is not true, children inherit approximately half of their DNA from their mother and half from their father (only approximately due to the presence of maternally inherited mitochondrial DNA) . Consequently, while the gene for breast cancer susceptibility (such as BRCA1 or BRCA2) may have an increased likelihood of being inherited with a feature of appearance such as hair colour, there is no basis for believing that a child has an increased likelihood to inherit susceptibility because of the presence of particular physical characteristics. Individuals have a wide range of beliefs about the origins of disease, many of which do not agree with the known scientific basis. These beliefs are based on factors such as prejudice, tradition and ignorance of the scientific basis for inheritance. Some factors t hat are often considered to be causative of disease include education, economic class, and weight . Consequently, Myra attributing the similarity in physical characteristics to a similarity in disease susceptibility does not have strong scientific basis, however, matches trends that are seen in the population, especially among lay people. Scenario Two Being able to work with colleagues and patients who have different cultural beliefs is an important part of nursing, especially in modern society. It is not enough to promote our own, predominantly Westernised, views on the rest of the world without considering their viewpoints and different expectations . In recent years, there has been a trend towards increasing cultural awareness and the development of cultural

Rimsky-Korsakov - Essay Example The Russian composer Rimsky-Korsakov in 1888 set one of these wonderful stories, the tale of Schaherazade to music. It should be noticed that "based on The Book of One Thousand and One Nights, this orchestral work combines two feature common to Russian music, and of Rimsky-Korsakov in particular in particular: dazzling, colorful orchestration and an interest in the East, which figured greatly in the history of Imperial Russia". Through all the movements of the suite run the theme of gorgeous women and wonderful teller, Schaherazade. Emotional, sensuously winding and full of inscrutability melody for violin solo, which is accompanied by harp, perform this theme. This is not just some excerption from an ancient eastern melody. It was composed by Rimsky-Korsakov himself, in the way that it is really seems the melody combines all the enchantment and inviting mystique of eastern lyrics. The same may be said about all other themes: orchestral, lyric-singing etc. They all synthesize eurhyth mics, figuration, and diversity of color of eastern music. Rimsky-Korsakov is best known for his mastership to paint beautiful pictures in music by using the colors of sound made by each instrument of orchestra. He had a color ear for music, and perceived the notes associating them with particular colors2. Note C D Eb E F G A Color white yellow dark bluish-grey sparkling sapphire green rich gold rosy colored The whole first movement depictures the sea, which appears again in the ending section of the final. In such way the composer margined his suite with glaringly blue, and sparkling sapphire colors. The theme of sea is falling from the theme of overbearing Sultan. The theme of Sultan is built on four notes of the describing whole tone scale. Immediately following this theme, almost interrupting it, is the gentle and passionate violin solo of Scheherazade. This is one of the loveliest melodies ever penned. "Listening to these two themes, and the sweeping music of Schaherazade's tales that transports us bodily into the magic of the 1001 Tales of the Arabian Nights, one can only wish that Rimsky-Korsakov had had the time to produce settings for the other 997"3. Some time after we forget about fearful governor as Allegro starts painting the picture of the sea. Accordingly changes the character of the first movement: now it sounds stately and on an even keel. This calmness is underlined with figuration of accompaniment, in which we hear decuman ocean waves. The main theme of the first movement is added by two accessory themes. One of them is a theme of Sinbad's ship. The other one is a theme of Scheherazade, Sultan's wife, who used to please her husband with the marvelous stories. It is remarkable that the wavy accompaniment, which appears as an essential element of the main part, disappears just for a while and then comes again, sounding almost throughout whole first movem
