Investigating the Cause of Global Warming Essay -- Global Warming Clim

Investigating the Cause of Global Warming Many people disagree on the issue concerning global warming. Some believe that human activities, various forms of polluting, are the main cause of global warming. Others think that not only have humans not affected the planet by any significant amount, but that not much global warming has even occurred. Many scientists think that pollution is the cause of global warming and the greenhouse effect. There is a lot of evidence to support this theory. In the United States alone, almost 15,000 pounds of greenhouse gases are emitted per person each year. From 1990 to 1997, these emissions have increased by 3.4%. The burning of fossil fuels is responsible for 82% of these emissions. Since the industrial revolution first came about, the amount of carbon dioxide in the atmosphere has increased by almost 30%. The burning of fossil fuels to power vehicles, heat buildings, and to power factories is the cause of the emission of 80% of the carbon dioxide that is released into the atmosphere. The amount of methane in the atmosphere has increased by more that 100% and the amount of nitrous oxide has risen by 15%. The burning of fossil fuels is also responsible for emitting 25% of the methane and 20% of the global nitrous oxide that is released. Some other emissions are caused by the increas e of landfills, agriculture, industry, and mining. There are also other greenhouse gases that do not occur naturally. Some of these gases are chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). These are byproducts of refrigeration, air conditioning, and foam production. The increase of greenhouse gases causes the atmosphere to trap more heat than it would naturally. ... ...be able to melt ice caps. I used to believe that action should be taken immediately to stop global warming so that our planet wouldn?t be severely damaged. Now, based on the evidence I have seen, I don?t think that pollution has such a large effect on the environment. Of course I do think that it is important for us to try to cut down on pollution. It will someday affect our descendants. However, I no longer think that a huge amount of money should be spent to solve this problem immediately. I think that each individual should be careful in their everyday lives to try to cut down on pollution. I think this will make our planet a better place for the future.

Globalization In Usa - 1244 Words

Britain’s vote to exit the European Union, Opposition by the U.S. to the Trans-Pacific Partnership (TPP), and the undergoing renegotiations of the North-American Free Trade Agreement (NAFTA) are just a few examples of the increase in anti-trade sentiments in recent years. Protectionist sentiments undermine the broader economic benefits of international trade and create uncertainty among trading partners. Trade liberalization is a key component of the world economic agenda required for sustained reduction of global food insecurity, poverty, and inequality. Trade boosts productivity, spurs innovation, lowers prices, and increases access to imports. For example, Canada’s productivity is estimated to have risen by 13.6% as a result of free†¦show more content†¦The economic literature acknowledges that decisions to export are based on both productivity and on the appeal of the firm’s products to consumers and businesses. Firms with higher productivity have lo wer costs, and firms facing a higher demand, have larger market shares (Li, 2014). While new entrants are often times just as productive, or even more so, than incumbent firms, they face lower demand, and thus higher attrition rates (Haltiwanger et al. 2014). New and potential exporters might be uncertain about how consumers and other businesses will perceive their product. Over time, however, a firm that experiences higher demand than anticipated will learn about consumer preferences in the new market and expand production. A firm that experiences less demand than initially anticipated, will revise its beliefs and cut back on production, and may even find it optimal to exit the market (Arkolakis et. al, 2017). A particularly large gap in the economic literature is that productivity and learning about demand have been assumed to be two separate processes that do not affect each other (Haltiwanger et al., 2014; Timoshenko, 2015). A cursory view of export behavior, however, suggests t hat demand learning is endogenously related to productivity growth.

Perfect Competition The Market Price Of An Product

Perfect competition describes a marketplace that no one participant can set the market price of an exchangeable product. This is generally considered an ideal, rarely found in markets today. There are some approximations, such as online auctions, such as eBay. Such firms’ demand curves are perfectly elastic. These markets are theorized to have an unlimited number of buyers and sellers. There are likewise no barriers to entry or exit. Monopolistic competition describes a marketplace offering differentiated products, and as such are not perfect substitutes. This is found in restaurants, shoes and other preference-driven goods. Such firms find a high elasticity of demand (in the long run), likely excess profits in the short term, and price setting available to them (as there are no perfect substitutes for their products; competitor prices are ignored). Oligopoly refers to an industry dominated by a small number of sellers with market power. They have the ability to limit or discount competition, and artificially earn excess profits. U. S. cell phone providers are often cited as a clear example of oligopoly, as the major providers effectively control the market. They set market prices for their goods or services. Barriers to entry are high, from capital investment to government permission to enter a market. They are notable by profit levels above that driven by competitive models, as they set the market price.

Mastering Audio free essay sample

Music, in most of its styles and forms that is targeting commercial distribution now undergoes a ? nal process of transformation and quality veri? cation known as Mastering. For those working within the audio industry, this process is an unavoidable step to pass through. The role of the mastering engineer is almost unknown and often unheard of. This status of the mastering process has over the years gathered itself an almost mythical status in the industry. The art itself is quite often misunderstood and in certain cases considered unimportant. Through this essay I hope to explore further into the role of the mastering process and the position it has held over decades with changes in styles, technology and mediums of media distribution. Mastering is the set of activities in the audio chain between the ? nal production of the music on an intermediary format and its transfer to a distribution format. (Dominique Bassal, 2005) ! During the early days, the process of mastering was not a separate discipline that was followed by a different engineer. We will write a custom essay sample on Mastering Audio or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page A recording engineer’s pro? le would involve recording onto a disc cutting lather. Before the year 1925, the tools used to cut records was unsophisticated and worked in a fairly mechanical manner without the use of electricity. By the 1930’s the advent of electricity in the audio industry like many other markets changed the way media was recorded, processed and ? nally distributed. The rise of the radio stations, microphones and the ampli? cation of the stylus that was previously driven just by a diaphragm into an acoustical horn has changed the way mastering works. The discs cut onto wax were used as stampers to press 78rpm discs using shellac-composite. This was the method of cutting/producing records before the advent of tape. Mastering/cutting Engineer ! Post the second world war, the recording of tape and micro groove LP were ? rst introduced. The introduction of tape recording changed the norm of master recordings almost always being cut direct to disc. This was the beginning of a separate engineer being in charge of using the session tapes to cut master discs. This person was not initially known as a mastering engineer but a â€Å"dubbing engineer† or rather â€Å"transfer engineer†. â€Å"mastering was a black art practiced by technical curmudgeons who mysteriously made the transfer from the electronic medium of magnetic audio tape to the physical medium of vinyl. † (Owsnski, 2007) Tejas Nair 106552 205. 1 BAP250. 1 Mastering Essay ! This change brought about the industrial belief that the process of cutting the master discs from recording session tapes was not a very different technical skill than the vinyl pressing operation. ! The biggest problem as such with vinyl has been to safeguard the largest possible part of the audio ? delity of the master tape, by troubleshooting and working around the numerous downfalls and obstacles brought about by the medium itself. The technology of cutting vinyl from tape came with its own set of limitations to a huge degree. To explain the groove on the record, the thickness of the hair carries pitch and tonal information laterally and the amplitude information vertically. ! The problems brought about by this system was that the bass frequencies would drastically affect the total width of the groove. This in turn would affect the determined length of the information being cut onto the vinyl. the thickness of the vinyl similarly affected the dynamic range available for each cut. The recording onto analog tape helped with these ? aws to a certain extent through having a tendency to roll off the distinctly sharp high intensity transients. This tendency was due to the saturation that occurred when hit with too much level, which would result in the stylus jumping out of groove or often burn the disc cutter head itself. ! Around this time larger record companies dealing with pop music were prioritizing the automation of the tape to disk transfer as much as possible in the interest of production ef? ciency. One of the biggest advancements this brought about was the possibility to determine the thickness of the grooves using analog computer circuitry. It eventually brought about the possibility of having record sides of up to, and in some cases beyond, 30 minutes. The equipment being used for the mastering process also had to be speci? cally developed for use in record production. The idea behind this was to protect the companies from the expensive cutter heads blowing up as well as to ensure a more quality consistent product.! The birth of the Mastering Plant ! It was not long before a few engineers in this industry realized that there might me a market out there for mastering that is done with superior care and skill. This brought about the birth of the ? rst independent mastering lab in Los Angeles during the late 60’s. The art of mastering became more about the attention to detail, skillful use of the highest grade equipment available and a devotion to artistic satisfaction. This trend soon grew into a business where a master tape sent to a mastering plant run by a credible engineer such as Bob Ludwig, Doug Sax or Bob Katz would result in a disc that sounded phenomenal. It was during this time that the name of the mastering engineer was listed on to the credits of the albums. Tejas Nair 106552 205. 1 BAP250. 1 Mastering Essay Mastering trivia: ! â€Å"A signi? cant step in this extension of the role of the mastering engineer, even if ephemeral and exclusively linked to a speci? c musical style, was the dance mix fad, today devolved, in a modi? ed form, to the DJ. A rhythmic pop song is delivered to the mastering studio with, along with its of? cial mix, a series of excerpts, sub-mixes of rhythm sections, solo voices, etc. The mastering engineer constructs an extended version of the song, destined for, among others, nightclubs, adding as required supplemental effects and even sounds from other sources. † (Dominique Bassal, 2005) Mastering today ! Mastering is still very much a part of the industry, although most of them no longer cut master discs from analog reel tape. The CD generation has de? nitely caused a huge change in the mastering process. This process is now known as mastering where the recording in its ? nal stage is brought in recorded on to a digital medium and is then sent for pressing. ! In the older days, each record company would have its own in house engineers working to a pre determined standard set by the company itself. These standards were for the calibration of recorders, level and metering standards, interfacing and conversion equipment, etc. A number of engineers would also custom build some of the equipment used in their studio. This time saw that the tapes that were sent to these mastering studios could have a consistency to quality and ? delity. The order of the songs on the record, short pauses between tracks and equalization would have already been dealt with. ! Today the mastering business is a very different market compared to back then. The material for an album made these days could have been sourced from a variety of different places, ranging from large studio rooms to a bedroom studio. The mixing on the record could have been done using just a computer and sometimes by the artist themselves. These changes make it a completely contrasting market to when the big record companies were around. It opens a new realm of artistic space to play with as well. This freedom however also affected the technical aspects of the production. ! It is due to these reasons that mastering engineers began to expect their clients to provide them the recorded and mixed product with certain measures taken into account. The client is requested to not ? nish aspects of the process such as song spacing, fades and ? nal master levels for each song. It is in the bene? t of the client to trust the mastering engineer to take care of such detailed aspects with the necessary skill set and experience. A fundamental point to remember in today’s technological free market is that technical competence cannot be taken for granted. ! Tejas Nair 106552 205. 1 BAP250. 1 Mastering Essay ! Today’s mastering engineers are expected to take a body of work that is recorded, produced and mixed and transform it into a sonic piece that is well balanced and is aurally pleasing to listen to. It involves a meticulous binding, processing and reinforcing of sound to translate the artistic vision onto various forms of playback. Mastering Equipment ! ! The equipment used in the process of mastering is a range of extremely high quality units that perform very speci? c tasks in the overall chain. The most important tool however is and will always be the attention to detail through years of experience and critical listening. ! Equipment used at this stage today is very relative to what is being achieved through the process itself. The aspects that are of prime importance through mastering are the conversion of audio information from analog to digital domains, the consistent but not squashed dynamic range, equalization and balance of the songs with respect to each other and the intricately combined ampli? cation done using consoles, compressors and limiters. Acoustics: ! Mastering is the last and ? nal stage between the product and its dispatch for replication and distribution. This is where the sonic ? delity of the album or any other work is judged technically to suite the various listening conditions and environments that audiences consume music in. Acoustics is amongst the most important tools to achieving a neutral space where the engineer can fully understand the strengths and weaknesses of the pre master. Monitors: ! Reference monitoring systems for mastering plants are very different from the ones used in the mixing and play back stages. Monitoring systems for mastering rooms can be two way or three way systems that divide the frequency ranges to separate drivers so that they are individually emphasized to then pay special attention to. Plants usually run two or three sets of references. Adam audio, Barefoot sound and Earthworks are some of the biggest names in Audio reference monitors for mastering. Ampli? cation: ! Ampli? cation is an important stage in the mastering chain and is integral to driving the sound clean and transparent through and out of the monitors. Another reason for ampli? cation is to have a palette of colors to pass the audio through. There are usually at least two different ampli? cation systems in a mastering plant. Tejas Nair 106552 205. 1 BAP250. 1 Mastering Essay Console: ! The console is the heart of the mastering chain where everything comes together. It is the Hub for the audio that is passing through the outboard equipment, convertors and the DAW. Manley, TK Audio and Maselec are highly renowned mastering console manufacturers. DAW: ! DAWs are the software environments within which the Audio is contained and worked with. There is a wide variety of programs that specialize in different need of the mastering process, For example Pro tools HD, DDP creator pro, Sequoia. EQ’s: ! Equalization is the process of treating speci? c ranges of the audio to strike a smooth balance that will translate the music onto systems that may not always reproduce the entire spectrum from 20Hz to 20KHz such as earphones and car audio systems. Buzz Audio, Prism Sound and GML are amongst the biggest names for EQ’s with regards to mastering. Dynamics processors: ! Dynamic range is an integral part of preparing music and audio to a level of industry standard distribution. These processors are categorized into Compressors, Limiters, Exciters, Expanders and Gates. They are used to gradually make the audio translate with a benchmark RMS and Peak level that varies in ratio across music, ? lm, television and radio broadcast. Manley, Cranesong, API and Tubetech make extremely high grade Hardware Dynamics processors for mastering. Convertors: ! Convertors are arguably the most important tools in the mastering chain today. The amount of media that is generated completely in the digital domain is signi? cantly huge. Converting this information to analog in order to be processed and worked with requires precision based high quality convertor components that can be very expensive. The conversion process also plays a huge factor in converting analog to digital considering the fundamental differences that exist between them such as hardware circuitry and software coding. Lavry Engineering and Apogee is at the forefront of building high quality convertors for mastering. Tejas Nair 106552 205. 1 BAP250. 1 Mastering Essay Digital Processors: ! An integral part of todays Mixing and Mastering is Digital Signal Processing. The tools available for use within a computer are much more cost effective and pretty close to replicating the results of analog gear and circuitry. The biggest names that have been developing the tools of this digital era are Universal Audio, Waves and McDSP, using modern technology and speci? cally designed chipsets to treat audio without losing its ? delity. Conclusion: ! The art of Mastering as a discipline was ? rst considered to be a technical process within the larger process of making a record. Over the decades this art form came to recognition when its artistic impact was noticed by people from the industry such as the artist and producers themselves. This brought about the Mastering Plant Revolution. The skill set and aesthetic value brought into the production process by mastering engineers have grown to be invaluable in this day and age of digital distribution. It is through this evolution across almost ? ve decades that todays mastering studio serves as the last and ? nal stage of technical and artistic quality control for most recorded media.
