Definition of Typification in Sociology

Typification is the process of relying on general knowledge as a way of constructing ideas about people and the social world. As we participate in social life, most of what you know of other people does not take the form of direct personal knowledge, but rather general knowledge about the social world. Examples When you go to a bank, you do not usually know the bank teller personally, and yet you enter the situation with some kind of knowledge of the teller as a type of person and of banks as a type of social situation. This enables you to predict what you can expect and what will be expected of you.

How Violent Media Affects Children - 949 Words

There is a very important social issue that must be addressed to save our future generations from decline. The social issue I will be analyzing is how violence in media affects children. â€Å"Thus brutality itself becomes at once the means to success and the content of success –a success that is defined in its most general terms, not as accomplishment or specific gain, but simply as the unlimited possibility of aggression† (Warshow 433). Doing evil deeds to reach a certain level of success is how a gangster reaches success and this perception of â€Å"bad† being â€Å"good† clouds children’s judgement to do the right thing. Children are wrongly influenced by many mediums including drug abuse in movies, anger management and video game violence. Violence in media affects children in a negative way by influencing them to use drugs, become bullies and mature into abusive adults because it gives people a false sense of reality towards violent behavior. The main reason is how children use violence to stand out in a negative way among other Children. Using violence to fit in with a group of people by doing drugs or being a bully towards others is a very common example. Many groups use peer pressure to appeal to the crowd. Using drugs has attracted many people to groups that deal drugs or promote the usage of drugs. â€Å"The studies also discovered that more than 14 percent of prime-time television shows portray tobacco use without any negative consequences, and more than 11 percent of AmericanShow MoreRelatedResearch Paper Outline on Violence in Media Contributes to Violence in Children888 Words   |  4 PagesIntroduction The media is generally seen by people as a way of conveying the truth.

Energy Harvesting and Nanotechnology Free Essays

Energy Harvesting and Nanotechnology| April 28 2011 | Energy harvesting generators are attractive as unlimited replacements for batteries in electronic devices and have been the focus of new researches for past years. This paper reviews the principles behind this technology and their integration to harvest energy. Also proposes a greener alternative for the production of quantum dots before the integration to new technologies. We will write a custom essay sample on Energy Harvesting and Nanotechnology or any similar topic only for you Order Now | Nanowires and Quantum Dots| Energy Harvesting with Nanowires and Quantum Dots Introduction Harvesting energy is the core of our modern human existence. We need to power our cars, homes, and personal electronics. T o power our technology we need energy. Most electrical energy is harvested in one of two ways. These ways are mechanically harvested or harvested from solar power. Mechanically harvested energy needs moving parts, for example, to turn a generator. Solar energy can be harvested through solar cells via the photoelectric effect. As technology becomes smaller and more compact, power conversion technology needs to also adapt to this changes. Nanotechnology has shown great promise to become the power generator for future nanotechnology. 1 That is the purpose of this paper to show how this technology works and is integrated to the production of energy. Nanowires have a diameter in between 20 nm and 100 nm. They can be made from many types of material, however most research is being done on silicon nanowires1-2 3 4 5 6 ; carbon and CdS/CdTe7 nanowires also are being researched. These nanowires can convert solar energy into electrical energy with enough efficiency to power small devices. This technology can create self sufficient nanotechnologies that do not need batteries or need to be connected to a power source. This new technology will be completely different to the macro-technology we have today, were we have to change out batteries or plug them into a wall. Self-sustaining technology is very green, because they do not need a non-renewable outside energy sources. Quantum dots are being researched as a viable alternative to silicon based solar cells. Quantum dots are small particles, or â€Å"nanoparticles†, of a semiconductor material, most common chalcogenides (selenides or sulfides) of metals like cadmium or zinc (CdSe or ZnS), which are usually from 2 to 10 nanometers in diameter. Because of their size, quantum dots display unique optical and electrical properties that are different in character to those of the corresponding bulk material. The most relevant of these is the emission of photons under excitation, which are visible to the human eye as light. Moreover, Quantum dots can be tuned to certain wavelengths based on their size and are able to produce more than one electron per absorbed photon. These molecules are generally made out of CdSe and are cheap, their synthesis is relatively green, and they have great stability over many years. They do not bleach like other dyes and their efficiency does not fade nearly as quickly as normal dyes. 7 Nanowires and quantum dots have become very interesting topics in chemical research. They have potential to start a new wave of technology and may be the future power source of almost every technology. This article is about how scientists can harvest solar power on a nanoscale, with quantum dot technology showing much promise as a green solution. Solar Power. Today, solar power is harvested by large photovoltaic cells (a solid state electrical device that converts the energy of sunlight directly into electricity) that are made of crystalline silicon; the generation of electricity from the sun was a landmark in Green Chemistry. However, these large panels are bulky and expensive. Silicon nanowires use the same mechanism for power generation, but are smaller and more portable. The coaxial silicon nanowires operate by using coaxial shells selectively doped to absorb photons and produce electrons. 1,3 Coaxial silicon nanowires have 2 shells and a core, figure 1 shows the nanowire and a view of the cross section of the nanowire. Figure 1. The blue outer shell is the n-type shell, the inner yellow shell is in the i-type shell, and the pink core is the p-type core. The diagram on the right shows how the holes (h+), and the photo generated electrons (e-) flow across the nanowire. (Adapted from figure 1 in Nature 2007, 449, 885-889) The outer shell is crystalline in structure which enables the wire to absorb photons. The semiconductor material construction made this nanowire operate like a diode. Diodes allow current to flow one way but not another. Diodes are very common in household electronics and circuits. This means that self-powered circuits can be created from these nanowires. , 3-4 Quantum Dots are able to emit three excitons from one photon through an effect called the Multiple Exciton Effect. An exciton is an electron and its hole. Quantum dots can be tuned to many different wavelengths of light, because the wavelength they absorb is based on the diameter of the dot. The material for quantum dots is more cost effective than silicon-based solar panels. Theoretical limits for power conversion efficiency are approximately 60% 7. This is an amazing efficiency, but there are some debates about how true this efficiency is. There is not much known about quantum dots still, the organic outer layer that is used to separate these particles seem to have photo-electronic effects as well. Figure 2, shows an experimental power generator utilizing quantum dots and a mechanical piezoelectric generator. Figure 2 This is a power generator that uses both solar and mechanical means to harvest power. The quantum dots are interlaced in the ZnO nanowires. The solar cell power conversion efficiency of this device was 15. 8%. Unfortunately, the process of making heavy metal quantum dots is not very green. Some processes require high temperatures and heavy material loss. Current production methods have seen some LCA assessments of quantum dots. There is a lot of waste developed during the production and purification of quantum dots. Mass-by-mass comparison with silicon solar cells, show that quantum dots require far more energy and solvent. However, since only a small amount of quantum dots are being used in technology and the long lasting and high efficiency of power generation gives quantum dots a better assessment in all environmental aspects except heavy metal emission. Since emerging technologies rapidly change, this assessment could be outdated in six months with a new greener synthesis. Proposal Greener QDs: Cadmiun free quantum dots In many parts of the world there are legislation that restrict and in some cases ban heavy metals such as Cd in many household appliances such as Lighting equipment , Electrical electronic tools, sport telecommunication equipment and entertainment devices. Many reports have shown that cadmium-based QDs were toxic at the tissue and cellular levels when their surfaces are not carefully functionalized. 1, 12 CuInS2 is a direct band gap semiconductor material with a band gap of 1. 45 eV. Thus, by tailoring their composition and size, it is possible to fabricate CuInS2 QDs that emit from the visible to near-infrared (NIR) region, with high quantum yield. More importantly, CuInS2 QDs are more suitable for biomedical imaging applications and integration in household devices because the particles are free from toxic elements such as cadmium, lead, mercury. The properties of these nanoparticles are very similar to those of CdS quantum dots, but the overall efficiency and shifts in spectra are still lower that the ones obtained by cadmium QD’s. More research needs to be done to increase the overall properties of this nanoparticles and their integration to electronic devices, but some ideas that are being currently tried are coating CuInS2 with organic materials that enables the particles to be more efficient and increases their luminescence. Currently this QD’s are being mass produced for example by Nanoco is a nanotechnology company located in Manchester, United Kingdom that uses a molecular seeding method adapted for other compound semiconductor materials, which have similar optical properties to those of CdSe quantum dots (such as the family of III-V materials), but do not contain heavy metals. So the possibilities for the implementation of this technology on devices that are in constant contact with humans are infinite, if new alternatives like this are implemented in future designs. Conclusion Self-sustaining technology is the end goal for these nanogenerators; this can lead to a green revolution in technology and reduce the emissions into our atmosphere. Currently, quantum dots are beginning to show amazing properties that may one day replace batteries and carbon- based energy production. Unfortunately, the current process for the synthesis of quantum dots generates too much solvent waste and uses too much power, but there is research trying to quantify the environmental impact and reduce it. Since quantum dots are an emerging technology, the production and utilization may drastically change in the coming years and hopefully a strong emphasis on low environmental impact will be on the forefront. Meanwhile this technology is being introduced in the solar energy production and medical procedures like targeting cell and biomarkers, giving results that promise a change in the way energy is produced.

Julius Caesar Vs Mark Anthony Essay Example For Students

Julius Caesar Vs Mark Anthony Essay Mark Antony is often seen as a confident, and devoted follower of Julius Caeser. Yet there is more to him then the eye can see. As the play progresses his characteristic changes. He began as a loyal follower of Caeser, to a shrewd flatterer, and finally a ruthless tyrant. Furthermore, Antony uses these various qualities to make him successful. Within the play, Antony uses flattering to achieve his goals. Following after Caesers death, Antony quickly learned that he must deal with Brutus, and he has the shrewdness to take advantage of Brutuss gullibility. Antony began by having his servant say, Brutus is noble, wise, valiant, and honest (III i 126). Beginning from this point, Antony intends to flatter Brutus and to work upon those personal qualities of Brutus, which represent his weaknesses. He later went to the capitol to flatter the other conspirators by shaking their hands and by saying, Friends am I with you all, and love you all.. . (III i 220) With this, it may seem that he had created a new friendship and trust with the conspirators, but he is actually plotting to seek revenge so he can take over Rome. He then uses his flattery to persuade the crowds at Caesers speech. He first started by making them feel sorry for him. This is evident as one of the plebeian responded, Poor soul, his eyes are red as fire with weeping (III ii 116). Thus he is now able to turn the crowds to go against Brutus and the conspirator by teasing them with Caesers will. In his speech he said, And being men, hearing the will of Caesar, it will inflame you, it will make you mad (III ii 144-145). With this he provokes the crowds to wanting him to read it. Although Antony uses flattery to get what he wants, he will also show respect for others with his devotion and loyalty. One of Antonys strong traits is his affectionate loyalty to Caeser. His devotion toward him goes beyond a simple friendship, but politically also. This is most evident when he presented Caeser the crown of Rome three times. This enactment depicted his dedication toward Caeser because he is willing to live under the rule of an ambitious tyrant. Later as Antony was left alone with Caesers body, he shows his true feelings about the conspirator and Caeser. As he kneels down toward Caeser he said, Thou art the ruin of the noblest man that ever lived the tide of times(III i 256-257). To prove his loyalty, Antony gives a confident and persuasive speech at Caesars funeral despite extreme danger on his own life. He began by expressing his grief and sadness. As the speech progresses Antonys emotion changed to extreme anger toward the conspirators when he told the crowd, Look you here, here is himself/Marred as you see with traitors (III ii 197-198). The crowd was so moved by his speech that they were willing to go to war against the conspirators, thus again Antony risked his life by creating a civil war. To Antony, loyalty was an advantageous quality a person could have. He emphasized this when he chose not to kill Lucilius, for he risked his own life to save his master, Brutus. This is not Brutus, friend, but, I assure you, a prize no less in worth(V iiii 26-27). Realizing the value of having loyal followers, Antony orders that Lucilius join his army and be protected. Eventually, Antonys loyalty will change into an envy of Caesars ambition and he will follow the path of the ruthless tyrant. .ufebe66ff86d4b9360861f8f6aed27189 , .ufebe66ff86d4b9360861f8f6aed27189 .postImageUrl , .ufebe66ff86d4b9360861f8f6aed27189 .centered-text-area { min-height: 80px; position: relative; } .ufebe66ff86d4b9360861f8f6aed27189 , .ufebe66ff86d4b9360861f8f6aed27189:hover , .ufebe66ff86d4b9360861f8f6aed27189:visited , .ufebe66ff86d4b9360861f8f6aed27189:active { border:0!important; } .ufebe66ff86d4b9360861f8f6aed27189 .clearfix:after { content: ""; display: table; clear: both; } .ufebe66ff86d4b9360861f8f6aed27189 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ufebe66ff86d4b9360861f8f6aed27189:active , .ufebe66ff86d4b9360861f8f6aed27189:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ufebe66ff86d4b9360861f8f6aed27189 .centered-text-area { width: 100%; position: relative ; } .ufebe66ff86d4b9360861f8f6aed27189 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ufebe66ff86d4b9360861f8f6aed27189 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ufebe66ff86d4b9360861f8f6aed27189 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ufebe66ff86d4b9360861f8f6aed27189:hover .ctaButton { background-color: #34495E!important; } .ufebe66ff86d4b9360861f8f6aed27189 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ufebe66ff86d4b9360861f8f6aed27189 .ufebe66ff86d4b9360861f8f6aed27189-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ufebe66ff86d4b9360861f8f6aed27189:after { content: ""; display: block; clear: both; } READ: Hsc Visual Arts: Artists Who Use Bodily Fluids EssayAs the play builds up, we begin to see Antonys ruthless state of mind. Antony first began to show his fierceness in his speech. He speaks of the conspirators sarcastically as honorable men. He then enrages the crowd by telling them that Caesars assassination was morally wrong, and that the conspirators are traitors. And again he showed his ruthlessness when he condemned his nephew to death by saying, He shall not live; look, by the spot I damned him(IV i 6). Antony is willing to ignore all ethical and moral considerations in order to concentrate on political practicality. Also at Phillipi,
