‘Stand Up Tall’ by Dizzee Rascal Evaluation Report

There are several features to our production which were included based on research in past examples. To try and create authenticity with our production became one of the aims because of he style of research done and its extensiveness on past examples. One key feature was the speed of the edited scenes. Researched examples always included a fast paced style and this was incorporated. This not only meant scenes of shorter but it increased the length of times given to develop the story. The increased number of scenes due to the nature of the music led to a development in the story which could be told to make up this number and to make up the duration of the track. One of the key strengths of our production I feel is the way in which it closely relates to its genre. With the speed of editing, the urban locations chosen and the ethnicity of the characters involved, it was a very genre specific video. One weakness however I feel is the lack of varying camera angles. Close ups were used a large percentage of the time. Understandably, due to the videos narrative nature and the fact that there are no scenes which involve speech embedded in our video, or cut-scenes, it is difficult to correctly convey feelings or reactions without needing to focus on a characters expression. However, there are more ways to do this. High angle shots can signify authority and low angle shots the adverse. Establishing shots could be used to set a whole scene to the audience. If we were given the chance to do it again, I would greatly vary the amount of types of shots used. It is important to add variety to the style of camera work to increase the size of the parameters for creativity, which is what the narrative style of our video did indirectly. An example in our video where more camera angles could have been incorporated is the scene which shows the phone call between Tariq, the main character, and his pregnant ex-girlfriend. Although the camera work here is good and it conveys successfully the message it wants to, it doesn't vary in camera angle between the two characters. It tends to stay with medium close ups. In a video I analysed called ‘Stand Up Tall' by Dizzee Rascal, the artist is in a majority of the shots but is seen from different angles such as over the shoulder, long shot, medium close ups and close ups. I think our group could have worked better as a team. The main flaw was our inability to meet up, discuss ideas and become all aware as to which stage of production we are at. We at times thought different things were occurring and we didn't all pull in the same direction until towards the end of production when editing. These are the sessions where we worked well as a group. When editing, we looked at the production and any idea brought up by one of our group members were considered. This process happened several times and this ensured us that we were all happy with the final production. Another disappointing thing about our group was the lack of met deadlines. However, this directly came as a consequence as a lack of deadlines set. Although the work was shared between the group, it was very disorganised as to when it should be done. It was very difficult for this reason to know whether we were ahead or behind schedule with the only dates determined was the final deadline for all work. Although I have no first hand experience as to how a real film production team works, I assume due to the scale of their work and the time they spend on it that they would be much more organised than we were. I feel a real film production team would make a priority a schedule to refer back to as to what should be done before a certain stage but we failed to do this. BBFC's film classifications detail parameters to meet a certain certificate. We wanted our production to be available for viewing pre-watershed and this meant it could not involve any swearing, scenes of nudity or scene of extreme violence. Our production met these criteria. I had decided to show ten members of our audience a screening of our music video in an attempt to establish how these members would appreciate its qualities and informs us of some flaws. I was happy with many of the responses because they were intelligent answers. I decided to outline nine features of our work and asked then on the questionnaire to circle one of the words excellent, good, satisfactory, disappointing and poor. And then there was a tenth open ended question asking them to detail how well they felt it went with the genre of music. The results of this investigation were positive. According to our results, our camera work and mise-en-scene features were very good. This could be down to the emphasis this took when deciding to produce a narrative music video with the absence of speech. The quality of our editing was though of well also. This could be down to the way we each combed through thr music video when editing and discussed ideas thoroughly during the editing process. However, one thing which disappointed was the lighting. It was at times unclear as to what was happening due to the poor lighting at times. The responses to the open ended question at the end of the production was positive. The most mentioned feature which related it to past examples was the use of scenes, synchronised which changes in the beat of the music and mentioned to speed of the editing. The synchronization of the beat to scenes was apparent in the very beginning when the door closes as the heavy beat drops in the music. And the fast paced editing came about as the research into previous examples showed us that it was important to music and music videos of this genre.

The Contributions of The Women of The Tragedy of Julius...

In a cast of over 30 characters, there are only two women. This is a statement describing the world renown play The Tragedy of Julius Caesar by William Shakespeare. These two female characters are Calpurnia, the wife of Julius Ceasar, and Portia, the wife of Marcus Brutus. Other than these two women, the cast is composed entirely of male characters. In a work of literature so populated by men, one may ask why Shakespeare takes the time to include any women at all. However, after further reflection, it is clear to see the reason as to why they are included. Upon including Calpurnia and Portia in The Tragedy of Julius Caesar, William Shakespeare deepens our understanding of their husbands, highlights the social values of the time, and†¦show more content†¦Asking this of Mark Antony displays clearly that Caesar believes Calpurnia to be at fault for them not, yet having any children. This shows that the men of Rome thought highly of themselves in every way. They were full of pri de and saw no flaws within themselves. With Caesar’s actions in Calpurnia’s presence we see the gentler, slightly less arrogant side to his personality. Also in having Portia’s presence, we see the more compassionate side of Brutus, her husband. We are shown Caesar’s gentler, less arrogant behavior when Calpurnia pleaded with Caesar that he not leave home that day, a request made due to her suspicions sparked by the soothsayer’s warning to beware the Ides of March. Caesar dismisses her feeling confident that the Soothsayer’s words were unimportant. However she continues in her attempts to convince him. â€Å"Mark Antony shall say I am not well,/ And for thy humor I will stay at home† (cite). Then, although he sees staying home on this day as a sign of cowardice, Caesar chooses to stay home. Although shortly after, Caesar reverts to his original plan, the fact remains true that for at least a moment, Caesar had made the less arrogant choice. Making this choice showed Caesa r is capable of changing his arrogant way of thinking under certain circumstances.In having Portia, Brutus’s wife, we see a new characteristic in Brutus as well.After Portia’s death Brutus says to Cassius, â€Å"No man bearsShow MoreRelatedAnalysis Of Shakespeare s Julius Caesar 1008 Words   |  5 PagesJulius Caesar Assignment Tess Macintyre IGCSE English Literature Discuss the contribution made by the two women, Portia and Calpurnia, to the play as a whole.

How Gangs And Their Social Meshwork - 1661 Words

When examining and analyzing gangs and their social meshwork, it is without a doubt that gangs are seen by the majority as social pests in the community. As a whole, these numerous gangs throughout the country are more than just a bunch of criminals covered in tattoos, they are people, with feelings, who just need positivity in their lives. Most gang members, living in impoverish conditions, grew up in households were they were abused, unloved, and neglected. They grow up with no positive social support and become accustom to violence and negativity. More often than not, these children grow up in family’s were gang life is the only life they know, because their family members are gang members as well. They witness domestic abuse, and disarray, and a large majority grow up in households were a father figure is nowhere to be found. Mostly raised by single mothers, these children become hyper-masculine, and feel the need to make up for not having a father, and also because gang l ife is masculinized by violence and gang-banging. They come to believe that violence is normal and all of this creates a domino effect of involvement into gang life. With no social support, and no clear direction, children take it amongst themselves to find a connection with anyone willing to show them some sort of family structure. Impressionable children find themselves turning to gang life as a means to have that sense of family they never had. In a gang they feel that they are protected and feel in

The Bombing Of Hiroshima And Nagasaki - 1593 Words

Bombing of Hiroshima On August 8th 1945 the first atomic weapon, a fission bomb, was dropped on the city of Hiroshima in an attempt to force the Japanese to surrender in World War II (Bombing of Hiroshima and Nagasaki, 2009). This event exposed the danger of nuclear energy. This massive explosion demolished 90 percent of the city and immediately killed 80,000 people. This was only the beginning though, tens of thousands of innocent people died due to the aftermath of radiation exposure for another generation (Rosenberg, n.d). This day marks one of the most controversial in history. While some argue that Truman’s decision to drop the bomb was in America’s best interest, others question the ethics of dropping the most destructive weapon in the history of war on a city filled with innocent civilians (Pavlik 1995). In 1939, President Franklin D. Roosevelt received a letter from Albert Einstein. In this letter, Einstein outlined a new field of physics in which the element u ranium could undergo nuclear fission, releasing an incredible amount of energy (Katayma, n.d). Einstein stressed the military importance of this new field of study, as Germany seemed to be on the verge of similar discoveries. He described the probability that a sustained nuclear reaction could be produced and the possibility of the construction of extremely powerful bombs (The Manhattan Project, 2014).

The Effect of Osmosis on Potato Cells free essay sample

In this experiment I am going to investigate the effect of varying concentration of a differing glucose solution on the amount of osmotic activity, between the solution and a potato tuber of a given size. The purpose of this experiment is to demonstrate how living cells rely on osmosis, the diffusion of water. Osmosis is the movement of water molecules (H20) from a region in which they are highly concentrated to a region in which they are less concentrated. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules, such as water, through but does not allow bigger molecules, such as glucose, to do so. The molecules will continue to diffuse until the area in which they are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than another. Investigation – Preliminary Experiment Strategy In my preliminary experiment I am going to be seeing how potato tubers react when placed in of 0m (distilled water) 0. 5m and 1m (glucose solution). I am doing this to gain some knowledge about how the potato tubers will be affected; so when I do my main experiment I will have basic knowledge on what will happen, this means I will be able to spot outliers more easily and learn from any mistakes which may have been made in the preliminary. Molar = (m) Mass/weight = (g) Depending on certain factors the osmotic activity between the potato tuber and glucose solution will either increase, decrease, or unaffect the mass of the potato, such as – whether the sugar to water ratio inside the potato and outside of the potato differ or not. Variables that could affect the amount of osmotic activity include factors such as: o Temperature Cells move quicker at higher temperatures, therefore the higher the temperature the higher the rate of osmosis. o Variety of Potato Different varieties of potatoes may vary in the quantity of water and/or glucose inside them. The more solution there is the larger quantity the glucose has to equalize over. o Pressure Areas of different pressure have different water potentials. o Surface area The larger the surface area, the more water can be absorbed into the cells, therefore altering the rate of osmosis. All of these factors will affect the experiment due to the nature of the potato cells, but the only variable I will be changing is the concentration of the glucose solution. Reliability Fair testing is essential in all investigations. If this experiment is not a fair test, i will obtain incorrect results, which could lead us to the wrong conclusions as they are not providing a true representation of the data at hand. Prediction My prediction is that when the potato tubers are put into the distilled water, it will increase in mass; I believe this because there are more water molecules in the water than there is in the potato cells, the water molecules will move by osmosis into the potato cells through the partially permeable membrane to create equilibrium. This means that the mass of the potato piece will increase and the potato will feel turgid. When the potato tubers are put into a high concentrated glucose solution there are more water molecules in the potato cells then in the solution; therefore the water molecules move by osmosis from the potato into the highly concentrated solution. This means that the mass of the potato tuber will decrease, and its appearance will be flaccid. The stronger the concentration of the glucose solution the more it will decrease in mass. Collecting Data Plan For this experiment I am choosing a set size for the potato tuber to be 3cm. This will ensure that it is a fair test throughout. I have also made sure that the first solution is distilled water, the second a concentration of 0. 5m and the third and final solution 1m. A potato tuber will be left in each solution for a period of 24 hours, I repeated each concentration twice times to try and get consistent results for each one. I will then work out an average of these three times, this helps to get as accurate results as possible. Results I created a graph compiled of all the evidence in the tables in a concentration (m) and mass change % (g) comparison. I have done a line graph as I believe this is the best way to portray my results accurately and clearly. Note: The graph and table have been attached overleaf. Interpreting Data Evaluating Evidence I believe that the experiment was successful as the results were as expected and were all in a similar range of one another; from looking at my graphs I can see that changing the concentration of the glucose solution affects the potato in differing ways according to the strength of the solution. The potato tuber in the 0m solution (distilled water) reacted as I expected it to, its mass increased as the concentration of glucose inside of the potato was greater than on the outside, thus the water entered the potato to try and create equilibrium. In the experiment with 0. 5m glucose solution, the mass of the potato decreased by a substantial amount, the average percentage change was -9. 53%; considering it wasn’t an extremely strong solution, it is a useful and unexpected result. The potato tuber that was placed in the glucose solution with a concentration of 1m lost even more mass than the 0. m solution; this was to be expected. The average mass change percentage was -17. 28%. This is a good result because the average of 1m is almost double the average of 0. 5m, this helps to show that the results are reliable as they follow the pattern they are expected to take. My graph and table were quite conclusive as they seemed to follow extremely closely to the line of best fit; the aero-bars are very close to the average which makes me believe that the experiment was accurate and reliable as the results are all very similar and follow the predicted ‘route’. Conclusion The potato tuber in the distilled water was the only one to gain in mass. This is because the potato became turgid as it soaked up the water molecules, by osmosis. The others decreased in mass. This is because the concentration of the solution was higher than the concentration of glucose inside the potato, this made them contract and shrink; whereas if the concentration of the solution had been lower, they would have expanded. Evaluation Generally, I think my results obtained were fairly accurate. From my preliminary test I have learnt that the three solutions were not enough, so I decided to have 6 solutions instead. This would make the graphs clearer and easier to notice any trends or patterns. During my preliminary test I also found that leaving the potato tuber in the test tube for 24 hours was not long enough to ensure that the process of osmosis was complete. So for my actual investigation I have decided to keep them in for four days, this would give the potato tuber enough time to complete osmosis as best it can achieve; it would also give me a bigger range between each result recorded. Investigation – Main Experiment Strategy Depending on certain factors the osmotic activity between the potato tuber and glucose solution will either increase, decrease, or unaffect the mass of the potato, such as – whether the sugar to water ratio inside the potato and outside of the potato differ or not. Molar = (m) Mass/weight = (g) Variables that will affect the amount of osmotic activity include factors such as: o Temperature Cells perform quicker at higher temperatures, therefore the higher the temperature the higher the rate of osmosis. Variety of Potato Different varieties of potatoes may vary in the quantity of water and/or glucose in them. o Volume of Glucose Solution The more solution there is the more the glucose has to equalize over. o Pressure Areas of different pressure have different water potentials. o Surface area The larger the surface area, the more water can be absorbed into the cells, therefore altering the rate of osmosis. All of these factors will affect the experiment due to the nature of the potato cells. The only variable I will be changing is the concentration of the glucose solution. Equipment ? ‘Number 5’ Cork Borer I decided to use this particular cork borer because it was a good size for the experiment, it wasn’t too large or too small. I needed a medium sized cork borer to allow sufficient osmotic activity to take place and for the changes in weight and length to be measured accurately. ? Potatoes of the same breed and age A reactant. The potatoes need to be the same breed and of a similar age because if a potato is old compared to another its water content could be lower.

THE ROUND RIVER Essay Example For Students

THE ROUND RIVER Essay In the essay the Round River Aldo Leopold was trying to say many different ideas that related together in the fight for nature preservation and restoration. One of Aldo Leopolds main points in his essay was that we as humans can not replace, rebuild nature. So before it goes to far, and gets to destroyed we must restore it. As people though we can only do so much and we cant restore it with foreign plants, but only the natural plants that originated there. So if we destroy an areas ecosystem then we can never restore, and replenish it to its original state and land consistency. In his essay Leopold said that we have radically modified the biotic system because we had to. Food chains now begin with corn, and alfalfa instead of oaks and bluestem, flows through cows, hogs, and poultry instead of into elk, deer, and grouse. Therefore we can never restore damage done but only reroute it. Another point in his essay is that all land is one mechanism and if you damage one part then you inter n damage or affect another part. So we cannot fully preserve land because our scientists cannot recognize all of the earths mechanisms. For instance if you kill the wolves then the rabbit and deerpopulation may rise without as high of predation. We will write a custom essay on THE ROUND RIVER specifically for you for only $16.38 $13.9/page Order now Another major point in his essay is that if we are going to prevent a species from extinction we must do it everywhere not just in one specific place. The worlds whale population is not going to rise if only the United States bans whale hunting. And if we dont enforce poaching laws and regulations. This also refers to if you tamper with one organism you affect a lot more. If we kill all the whales not only can we not use them but larger sea predators like sharks cant either. So they will be forced to feed on smaller sea life and then damage our sea food supply by eating other fish that we eat. So we as a whole must conserve on our supplies of natural objects with our exponentially growing population. We are also over concerned with now compared to the future which I believe to be more important . The world is to caught up in todays tinkerings to think about the end effects. Leopold stated that with each substitution of a tame plant or animal for a wild one, or an artificial waterway for a natural one is accompanied by a readjustment in the circulating system of the land. We do not foresee or understand these things unless it affects us . The essay has defiantly stood the test of time well, or why else would I have to read and write about it now? All of his major points in the essay have proved themselves true and are still being referred to by scientists and naturalists today. Bibliography:
