Case Study - Essay Example The combination of satellite, cable and fiber based broadband penetration together with targeting, interactivity, and company’s knowledge of people’s physical address and other contact credentials has launched a new era in marketing, organizational communication and advertising (Institute for Innovation and Improvement, 2006). ITV (an acronym for Interactive Television) is a range of technologies which has blended data services together with the traditional television technology. It entails enhancements and interactive contents. Interactive Television is enriched with providing interactions, rich entertainments, more information regarding various shows, props together with all the personnel responsible in its creation. Basically, Interactive television combines the features of the traditional television with interactivity which is enjoyed by people through a network such as LAN, WAN and internet (Interactive Advertising Bureau, 2011). Programming of interactive Television ranges from links to websites, richer graphics, and electronic communication among online users through a back channel. As a result, there is on – demand delivery of content together with services such as shopping, banking, ticket booking, among others (Institute for Innovation and Improvement, 2006). Digital Interactive Television exists in several forms and are manufactured by different companies. One form of Digital Interactive television is the Set top Boxes. This kind of Interactive Televisions are made by companies such as Microsoft, Motorola, Scientific Atlantic and Pace. This types of televisions are designed specifically to run interactive television services. During the manufacture of these products, the interactive TV is designed in such a manner that it can collect data from the user to the service provider (Institute for Innovation and

Abigails Party Essay Example for Free

Abigails Party Essay This is shown when Beverly suggests â€Å"[getting] pissed† after having an argument with Laurence. The use of the word â€Å"pissed† as a colloquialism for drunk could be seen as being symbolic of Beverly’s true social class seeping through the performance she continuously puts on throughout the night. This is humorous for the audience as Beverly spends a great deal of time and effort in the first part of Act 1 making sure that she is able to impress guests like Angela and Tony and try to feel in the same social class as Susan. She does this by adding a copy of â€Å"[placing] a copy of Cosmopolitan magazine in the magazine rack† and â€Å"[putting] on a record (Donna Summer: Love to Love you† among other things yet after one small spat shall we say with her husband represses back to having the personality the audience believes she’s trying to hide. Some might also say that Leigh’s use of fools near the end of Act 1 is to create after a very tense moment. An example of this would be after Laurence makes quite a long speech which gives us an idea of his views about people as he says that people often â€Å"just drift through life, without any real aims†. He also describes these people as being â€Å"weak†. Both these points are extremely serious and also quite angry. This means that when Angela tells a story about the time â€Å"[she] went to a party† right after these serious points, the audience feels sorry for Laurence as no one seems to be listening to him, but they also can’t help but laugh at Angela’s complete vacancy of points Laurence was making. This makes Angela a clear example of a natural fool as she has no real knowledge about when she is making an irrelevant point. It could also be said that the comic convention of foolishness is used when Angela and Beverly doesn’t know when she is saying something inappropriate or hurtful. An example of this would be when they try to reassure Susan about her daughter Abigail’s party but end up doing the exact opposite by Beverly saying that â€Å"teenagers get over-excited† to which Angela add that â€Å"it all starts with one kiss†. This is humorous as while trying to do one thing, Beverly and Angela end up doing the exact opposite without realising it which is a classic example of a natural fool. This part of the play could also be seen as cringe comedy because of the sympathy the audience feels for innocent Susan who has been kicked out of her house by her daughter only to e made to feel even more uncomfortable in Beverly’s house with her continuous points about teenagers and their rumoured carelessness which, including the gin and tonics Beverly gives Susan, causes her to be physically sick at the very end of the act. Hypocrisy could be considered to be another comic convention that is shown at the end of Act 1. This is particularly something that Beverly shows more than anyone else as when she is describing teenagers as having â€Å"a drink in one hand, a cigarette in the other [and] they’re having a bit of a dance†. The hypocrisy of this is that Beverly throughout the act is continuously refilling people’s drinks, offering cigarettes to everyone and is described on page 42 as â€Å"[proceeding] to have a dance solo in front of the others†. This is humorous as it makes it plainly obvious that Beverly is a natural fool because she is, in many ways just as childish as the teenagers that were in Susan’s house. This is another case of the audience feeling superior to the characters on stage as they when seeing the play would mostly be middle class and therefore they would also probably not be as childish as Beverly or Angela. Leigh’s uses of comic conventions are, in my opinion, used to establish a social ladder change between when the characters are first introduced and when the act finishes which is shown with Susan coming to the house with a bottle of red wine and ending up being sick in the toilet. Leigh’s clear use of comic conventions such as hypocrisy is also to breakdown the difference between sophistication and childishness. Mostly though, Leigh uses comic conventions to get the audience to question where they stand on the social ladder and if it really matters in this world.

Kyrgyzstan :: essays research papers

The collapse of the Soviet Union created 15 new states. These states over the last 5 years have all struggled with economic, ethnic, political and territorial problems left to them by the Soviet empire. Kyrgyzstan, is a former Soviet Republic (FSR) located in the Central Asia. This paper will give a statistical representation of the state, Kyrgyzstan. The statistical data will reflect the basic geography of the subject country containing population, size and location. This miniature report will also contain brief descriptions of current political and economic situations. Included in the current information section of this report, is an outlook for possible near future events concerning both political stability and economy. Kyrgyzstan is located in the southern area of the former Soviet Union. Its boarders are defined by China to the east (& South), Kazakhstan to the north (& Northwest), Uzbekistan directly west and Tajikistan to the south (& Southwest). Kyrgyzstan features 76,641 square miles of land, which consisted of .9% of the former USSR's land-mass. The land is primarily used for pastoral purposes. Only 7% of the farmable land is cultivated. The population is approximated to be 4,258,000 people (see Figure A). The Kyrgyzstan populace has experienced a 25.3% growth in population during the last 12 years (Population Growth Data from 1979-1991), and a birthrate at 29.1/1000. Population distribution is 61.9% in rural areas and 38.1% in urban centers. City & Population The top 4 cities are: Bishkek (formally Frunze) 616,000 (Capitol) Osh 213,000 Przhevalsk 64,000 Naryn 26,000 In June of 1990 ethnic violence arose in the city of Oh. Kyrgyz clashed with Uzbeks resulting in a bloody conflict which was eventually suppressed by Soviet Interior Ministry troops. This clash outlined political and economic problems present in Kyrgyzstan even when the USSR was still existent. These ethnic clashes in Oh served to cement political groups who were organizing outside of the communist party during Perestroika. It also gave voice to the large economic problems in central Kyrgyzstan. The "head of state" and leader of the communist party in Kyrgyzstan was Absamat Masaliev. Masaliev invoked policies which were rigid and served to enhance the existing social problems. Because of the decline present in the government's abilities to meet the expectations of the populace, the allowances granted by the Perestroika police and ethnic tensions, communist authority in Kyrgyzstan was challenged. The communist party's rule came to an end in October of that same year.

Isolation of Single Human Hematopoietic Stem Cells Capable

Isolation of Single Human Hematopoietic Stem Cells Capable of Long-Term Multilineage Engraftment A variety of distinct progenitors arising from self-renewing hematopoietic stem cells (HSCs) allow for the production of mature blood cell lineages. Human HSCs are poorly understood due to their rarity and difficulty to segregate them from multipotent progenitors (MPPS) to obtain a pure population for analysis. This study investigates the determining factors of HSCs.It appears that the majority of HSCs are CD34+, as hown by transplantation and xenograft repopulation assays, however most of these cells are lineage-restricted progenitors and HSCs are therefore rare. Enrichment of HSCs seems reliant on CD45RA, Thyl and CD38 expression. Further study into the role of each of these factors in HSC differentiation is required. In this study a range of assays were carried out in an attempt to identify and separate HSCs from MPPs. Recently it was shown that a depletion in Thyl expression in the CD 34+CD38-CD45RA- compartment of lineage-depleted cord blood was ufficient to separate HSCs from MPPs.However, further studies gave rise to concern surrounding this theory. They then used an optimized HSC xenograft assay and flow- sorted cord blood HSCs and MPPs into functionally characterized fractions. Data obtained from this assay suggested that cells with extensive self-renewal potential exist in both Thyl+ and Thyl- subsets. However, more extensive research was required to investigate the disparity in secondary transfer efficiency between subsets. To distinguish the cause of such disparity the Thyl subsets were sorted intoThyl+ and Thy- cells and cultured with stroma cells known to express HSC supportive ligands. The results demonstrated that the Thyl- compartment is heterogeneous and contains a small fraction with repopulating activity and a larger fraction with MMP- like activity and therefore may account for the differences in efficiency between subsets. To further distinguish HSCs in both Thy+ and Thy- subsets they analysed cell surface markers and found only CD49f to be differentially expressed between subsets.Next they investigated whether HSCs could be identified using CD49f expression. Data recovered indicated that human HSCs are indeed marked by CD49f. Further tests were carried out on Thyl-CD49f+ and Thyl-CD49f- subsets. Results revealed Thyl-CD49f- cells are short term HSCs as they fail to engraft long-term, indicating that these are MPPs. Investigation into the role of mitochondrial dye rhodamine-123 (Rho) in HSC enrichment. Results indicated twofold enrichment for HSCs compared to Thyl+ alone as opposed to Thyl +Rholo.The next aspect nvestigated was whether the addition of Rho to Thyl +CD49f+ would permit robust engraftment of single human HSCs. This investigation was carried out using single cell transplantation with two separate experiments focusing on engraftment and Thyl +RholoCD49f+ cells provides evidence that human HSCs express CD49f. Th ese findings illustrated by Notta et al. will aid in identifying gene regulatory networks that govern human HSC function and therefore allow manipulation of human HSCs ex vivo with the aim of overcoming the barriers associated with transplantation.

Benito Cereno essays

Benito Cereno essays After reading Herman Melvilles Benito Cereno, it is clear to me that Melville views the institution of slavery as a cruel and inhumane act. Slavery is the evil of the story. The slaves on the San Dominick rebelled because they were treated cruelly. It is wrong for one person to own another and look down upon them and treat them poorly. Evil seems to breed evil, and therefore, the slaves revolted with violence. In the story there are two captains; Benito Cereno and Captain Delano. Cereno is captain of the San Dominick, and although he is the captain of the ship which holds the slaves, he is truly a good man. He too seems to be a victim of evil. The slaves rebellious behavior turned him into a very edgy and nervous man. Although he may not seem like a good guy, Cereno showed his goodness when he jumped into Delanos boat to warn him of the danger that lied ahead for his crew and himself. Delano is alo a simple, good-hearted man. He is a good captain and runs his ship well. While on the other hand it seems that Cereno does not have that much experience. That is why Delano immediately went and offered his assistance to Cereno when he saw the San Dominick aimlessly wandering about the waters. Delano does not always see things as they really are because he is a very naive person, and it is because of this trait that he does not really realize all that is happening aboard the San Dominick. At the times when he did have a suspicion about the happenings of the ship, he would just tell himself he was being silly and forget about it. After he actually realized the chaos that was happening aboard Cerenos ship, Delano sent his crew to take down the slaves, and it is he who saved Cereno and the ship. ...

Ping-Pong Ball Bounces Essays

Ping-Pong Ball Bounces Essays Ping-Pong Ball Bounces Paper Ping-Pong Ball Bounces Paper This section is mainly based on putting my planning into action, hence all of the practical work and not a lot of written work. The averages in the table are recorded to the nearest cm. Observations My results table shows that as the height of the drop increases, so does the average bounce. This is illustrated in the table whereby at 50cm the average bounce height is 36. 6cm, and then at 120cm the average bounce height is 75. 2cm. If I take away the height of drop from the height of bounce I can see that for each height the energy lost in sound and heat is fairly similar each time the ball is dropped. Height of Drop (cm) Potential Energy. (J) Kinetic Energy (J) 50 1200 1200 60 1440 1440 70 1680 1680 80 1920 1920 90 2160 2160 100 2400 2400 110 2640 2640 120 2880 2880 I can see from my table on potential and kinetic energy that as the height increases the potential energy increases and as this increases so does the kinetic energy as more energy is been converted. Analysis My graph has a straight line of best fit, which suggests that my results are proportional. This means that whatever happens to one factor, it does the same to the other. In my experiment, as I increased the height of the drop, the height of the bounce increased as well; therefore my prediction was correct. This trend occurred, because the higher the ball was dropped the more potential energy it had. When the ball was dropped the potential energy was converted into kinetic energy and since energy can neither be created or destroyed, only converted it will move at a faster speed; therefore when the ball hit the bench some of the energy was transformed into sound and heat. The energy left after impact and the fact that the upward force is dominating the downward force causes the ball to be forced back up into the air. The more kinetic energy at the bottom, the more can be converted back into potential energy, therefore the ball bounces higher. There are no obvious anomalous results and there is strong positive correlation between the height of the drop and the height of the bounce, as the points are fairly close to the line of best fit. Evaluation My experiment went reasonably well and efficiently, due to the plan that I had drawn up beforehand. I received fairly reliable results from which I drew a firm conclusion. I would not alter the amount of results next time as I managed to gain a maximum outcome in the time selected. I think that the experiment was fair to some extent, because I controlled all other identified variables and only varied the height. However there were some problems that occurred, which fortunately did not affect the results dramatically; therefore there were no anomalies. I can see from my plan that I conducted a fair test, whereby I used a ruler as a marker each time to help in gaining more reliable results, I repeated the experiment three times and took five readings for each height, I kept the angle of the ruler constant each time, I used the same equipment each time, I kept the mass and the temperature constant each time and I dropped the ball on the same surface each time. The problems that occurred when doing this experiment were those, the ball didnt bounce in a straight line some of the time; therefore it was difficult to receive good readings. This was most likely to have been caused by the wooden bench being uneven and I could restrict this from occurring next time by using a spirit level. The results could have also been affected slightly, because there could have been a crack on the section of the bench where the ball was dropped. I could varnish the bench next time so that there arent going to be any cracks that are liable to affect the results next time. The ruler that I used as a marker was not as efficient as using a light beam or a video camera, because by using a light beam I would have been able to read off the readings more accurately and with a video camera I could record the experiment and then use pause to freeze the picture and then read off the values. I could extend my investigation further by doing the experiment again, under exactly the same conditions, but this time I would investigate how a different mass of ping-pong ball affects how high it bounces. Even though I havent varied the mass in this present experiment, by doing this extended investigation I can determine how mass may be another major factor, which might affect how high a ping-pong ball bounces. Accordingly I can progress further in this area of physics and this will help me in my understanding of this subject.
