Global Title Translation Essay Example

Global Title Translation Essay SS7 Tutorial Global Title Copryright SS8 Networks 2002 Before we get deeply into the subject of Global Title, it might help to get a very broad view of exactly what Global Title is. Simply defined, it is an address. But it is not an address of a node in the SS7 network (DPC, SSN). Instead, it is an alias for such an address that needs to be translated into an SS7 network address. With that definition out of the way, let’s quickly review what we know about SS7 addressing in general. To begin with, each User Part approaches addressing in a different way. The MTP (Message Transfer Part) has a job that is limited to reliably transferring messages over the links in a link set. That is, MTP only cares about the address of the node at the other end of the links it is tending. Therefore the only addressing the MTP requires is the SPC (Signalling Point Code) of the node at the end of its links. MTP sees this address as the Destination Point Code (DPC) of all messages it sends over the links. The only concern MTP has for any other location in the network is to be able to make use of the final destination of the message to help it pick out one link set from all the available linksets as the best one to use for sending the message. This is what MTP routing is all about. ISUP addressing is different. In normal Call Control use, ISUP addresses a switch at the other end of its trunk connections. For the SS7, this too means using a Destination Point Code (DPC).

The job of addressing all other locations falls to the SCCP. Actually SCCP could be used to address the same switching locations as ISUP. If it were used in this way, SCCP could be used for end-to-end signal routing in conjunction with ISUP. But since the usual switch-to-switch routing of ISUP provides complete circuit information for all switches along the voice path, SCCP is rarely used in this way. Like the other User Parts, SCCP can, and does, make use of DPC. This address alone can be used to get a message to any node in the global SS7 network in the same way that a telephone number can be used to address any telephone in the global telephone network. But SCCP addressing needs to go beyond this method of addressing. The reason is that at each DPC there is a â€Å"system† operating. That system may be a Call Control application or a database or some other program of some type. The problem is that within that system there may be multiple applications running. Thus a Signalling Point Code (which is addressed as a Destination Point Code) may be the home of both a Credit Card Database and an 800 Number Database. Using the DPC as the SS7 address will get the message delivered to the â€Å"system† but it won’t get the message delivered to the appropriate database application. For this purpose, a separate identifier of a system within the system is required. That identifier is the Subsystem Number (SSN). It may be tempting to think of SSN as a database identifier. And, indeed, an SSN will be applied to a database even when only one database application is available at a specified DPC. But, avoid the temptation. The truth is that SSN is also used to sub-address any location at which multiple applications are running. For example, a switch offering several features may use SSN to separately identify each feature. Think of SSN as simply an application identifier. That brings us to what you came for. The third addressing mechanism employed by SCCP is the Global Title, You might say this is the address used when the location requiring information doesn’t know the address. A Global Title implies the need for translation. Before you become too confused, let’s try an example. If you dial an 800 number, the switch to which you are connected becomes more confused than you are right now. The reason is that every number to which the switch can route has a geographical reference which the switch maintains in its own routing table. In North America, the North American Numbering Plan (NANP) provides the clues for that routing. So, for example, if you dial a â€Å"1† first, the switch knows it must make a connection to a long distance switch. The long distance switch will choose from among its connections to route the call into the region suggested by the area code. Then the routing goes to the switch in the appropriate exchange code. And, finally, that switch selects the appropriate line number. But you may have dialed 1-800-FLY-AWAY. The numbering plan is useless. The switch can’t even begin to make a connection. Instead, it sends a request into the SS7 network which essentially asks, ‘Will someone look this number up in an 800 database and translate it into an NANP number that I can route? Such a number is returned and the switch proceeds as if that number had been dialed in the first place. The switch can always get the information from such a database as long as it has the DPC and SSN of the 800 Number application in its SS7 routing table. But, therein lies a problem. Every day, new services are deployed into the SS7 network around the world. Some of them are proprietary and are, therefore, accessible on ly to the switches in the same proprietary network. Others are intended to be offered to other networks for a fee. So, here is the problem. If a service becomes universally available, does that mean that every switch on the planet needs to add the location (DPC) and identifier (SSN) to its SS7 routing table? Obviously if that were the case new services would spread slowly; and each switch would have to maintain huge tables of routing information. A better answer is to keep that information at a much more limited number of locations in the network (such as STPs) and allow the switches to identify their requests for information without identifying where, or from what applications the information can be retrieved. That means that when a switch wants a translation, it need only identify the nature of the translation needed (for example, 800 number to NANP number) and send the request to a location whose routing table tells it where such translations can be performed. A single location in the routing table of the switch (such a location as an STP) may serve to provide 800 Number translations, 900 number translations, Credit Card validation, etc. Even the first location which receives the request does not have to maintain a routing table of all locations on the globe. Instead, it may have a table which indicates that all requests in several similar categories should be sent to one location while requests in other categories can be sent somewhere else. All of this is possible because, with Global Title requests, the originator of the request does not need to know where or what application can provide the answer to the request. Global Title has even more uses. For example, the STP may be able to send Dialed Digit translation requests to either of two databases at two different database nodes. The receipt of a Prohibited signal (indicating the database is unavailable) from he SCCP at one of the database locations can tell the STP to change its lookup to another Global Title Table. The translation there, in turn, can result in address information used to send queries to the backup location The drawing below will illustrate the concept (but obviously not the coding) of Global Title queries. With the concepts firmly implanted we’ll move on to the actual coding.

As an alias addressing mechanism, Global Title can obviate the need for ubiquitous ponderous routing tables. (Actually I just said that to see if you were still awake). It can also hide network assets and provide greater control for conditional rerouting requirements. e9 14 45 27 17 1 SCP 10-20-05 SSN 123 Perhaps the biggest mystery surrounding the use of Global title is the meaning of each of the fields in a Global Title message. We’ll try to destroy that mystery next. Calling/Called Party Address To begin with, this contains all of the information required to identify the originator and the intended destination of the message. To understand why these values are important it might help to examine the way in which a Global Title request travels around the SS7 network. 1. An SSP receives dialed digits which it cannot use to route a call in the PSTN (e. g. an 800 number). 2. The switch consults its SS7 routing information to determine where to send the numbers for translation. If there is no information about the SS7 location of the translation table, the query may be sent to an intermediate STP whose routing table indicates where to send queries for translation. The message from the originating witch contains fields to indicate the full nature of the query. Address Indicator Foretells the type of addressing information to be found in the address field. This can be a single type of address or any combination of the address types Signalling Point Code, Global Title (e. g. Dialed Digits) and Subsystem Number. This field tells the receiving node what kind of addressing information to look for. The following tabl e indicates the significance of each of the bits in the octet with the bits numbered in the order in which they are sent/received. 8 7 6 5 3 2 1 Network Routing Indicator Indicator (Nat/Int) Global Title Indicator Point SSN Code Indicator Indicator Bits of the Address Indicator The following tables list the contents of the Address Indicator bit by bit and indicate the significance of bit placement within the octet. Bits #1-2 xxxxxxx1 xxxxxx1x Signifies: The address contains an SSN The address contains an SPC Bits #3-6 xx0000xx xx0001xx xx0010xx Signifies: No Global Title included Global Title Includes Translation Type, Numbering Plan and Encoding Scheme Global Title Includes Translation Type Only three possible combinations of bits 3 through 6 are given in the table because the remaining combinations are either spares for National/International networks, are unassigned in the U. S. , or are reserved for future use. Since multiple address elements may be used, bit #7 is used to identify which of these elements should be used for routing, Bit #7 x0xxxxxx x1xxxxxx Signifies: An SCCP translation is required. Therefore routing should be based on the Global Title in the address. An SCCP translation is not required. Therefore, routing should be based on the DPC (found in the Routing Label) and the SSN (found in the Called Party Address. Bit 8 is used to identify the address as national or international as shown in the following table. Bit #8 0xxxxxxx 1xxxxxxx Signifies: Both the address indicator and the address are coded according to international specifications. Both the address indicator and the address are coded according to national specifications. At this point it might be helpful to further explore both the Address Indicator and the actual Calling/Called Party Address. In the text preceding these tables we spoke of the actual address before we spoke of the Address Indicator. We did this in the hope of helping you to understand the need for the Address Indicator. In the message itself, the Indicator comes first. This allows the receiving side to determine how it must interpret the data in the Address before it has seen that data. Following the Address Indicator comes the actual Called/ Calling Party addressing. As can be seen from the Global Title Fields of the Address Indicator, the first octet of the Address may be a Translation Type. The next octets may be a Signaling Point Code, and the final octets may be the actual Global Title Address itself. We have repeatedly use the word may here because, as you can see from the Address Indicator, the Address may not even be a Global Title. As you can also see from the indicator, when Global Title is present, it may contain a Translation Type, a Numbering Plan, and an Encoding Scheme. We’ll examine these values next. Remember that we started by defining Global Title as an address. Subsystem Number and Signaling Point Code are also addresses. The difference is that the Global Title is an address of variable length and, perhaps of variable format which requires translation. For example, the Global Title may be the digits that were dialed which the switch was unable to use because they were not in North American Numbering Plan format. Global Title Format Following a Global Title Indicator value of 0001 In the Address Indicator Address Information N u m b e r i n g P l a n E n c o d i n g S c h e m e Translation Type Octet 3 Octet 2 ( above) Octet 1 A glance back at bits 3-6 in the Address Indicator should serve to remind you that it can indicate there is no Global Title Address in the message. It can also indicate that there is a Global Title Address and that the address includes a Translation Type. Or, it can indicate that there is a Global Title Address and that the address includes Global Title Translation Type, Numbering Plan and Encoding Scheme The previous paragraph contains some of the terms which seem to provide some of the greatest confusion over Global Title. You now have most of the information you need to understand Global Title. With a little luck, if we can clear up these final mysterious terms, all the pieces of Global Title should finally fall into place. Translation Type Global Title can be used in numerous ways. Therefore the possibility for many different applications requiring Global Title Addressing also exists. Such applications may be unique to a specific network, or they may be in use so generally that they are common to numerous networks. When the services of an application in one network are requested at a location outside that networking, certain internetworking applications may also be involved to transport requests and responses between networks. For example, telephone calls can be charged using cards issued by service providers or by banks and other types of financial institutions. The caller is required to enter a PIN number when making the call so that an application can validate the card through a database application. This is such a common application that the ANSI standard of 1996 has defined it as the Identification Card Application Group and has assigned to the Translation Type byte the value of 00000001 (decimal 1) Other applications are becoming universally available, and, a a result both the most recent ANSI and ITU standards are beginning to assign values for these services so that they may be used as standardized values across the SS7 network at large. SCP assisted services (such as 800 number translations) are another group of universal services which have been assigned their own Translation Types. Despite the growth of such commonly used services, the standards organizations have resisted the temptation to assign all 256 values which can be represented by the Translation Type byte. Indeed, under the ANSI standard an entire range of values (11000000 to 11111001) have been set aside for internal network usage. The table on the next page identifies the assignments in the ANSI standard. Translation Type Coding Decimal Value 0 1 2 3 4 5 6 7 8 9 to 31 32 192 to 249 250 251 252 253 254 255 Notes: reserved* The value 253 has been used for network specific applications as well as for the 14 digit Calling Card application while the value 251 has been used for both network specific applications and for the Call Management application. ** The value 254 is already in use for some internetwork applications such as 800 service. Network providers not using this value are cautioned to consider potential conflicts before employing the same value for network specific applications.

10 Facts About the Geography of the Pacific Northwest

10 Facts About the Geography of the Pacific Northwest The Pacific Northwest is the region of the western United States located adjacent to the Pacific Ocean. It runs north to south from British Columbia, Canada, to Oregon. Idaho, parts of Montana, northern California, and southeastern Alaska are also listed as parts of the Pacific Northwest in some accounts. Much of the Pacific Northwest consists of rural forested land; however, there are several large population centers which include Seattle and Tacoma, Washington, Vancouver, British Columbia, and Portland, Oregon. The region of the Pacific Northwest has a long history that was mainly occupied by various Native American groups. Most of these groups are believed to have been engaged in hunting and gathering as well as fishing. Today, there are still visible artifacts from the Pacific Northwests early inhabitants as well as thousands of descendants that still practice historic Native American culture. What to Know About the Pacific Northwest One of the first United States claims to the lands of the Pacific Northwest region came after Lewis and Clark explored the area in the early 1800s.The Pacific Northwest is highly active geologically. The region is dotted with several large active volcanoes in the Cascade Mountain Range. Such volcanoes include such Mount Shasta in northern California, Mount Hood in Oregon, Mount Saint Helens and Rainier in Washington and Mount Garibaldi in British Columbia.There are four mountain ranges dominating the Pacific Northwest. They are the Cascade Range, the Olympic Range, the Coast Range and parts of the Rocky Mountains.Mount Rainier is the highest mountain in the Pacific Northwest at 14,410 feet (4,392 m).The Columbia River, which begins in the Columbia Plateau in western Idaho and flows through the Cascades to the Pacific Ocean, has the second-largest flow of water (behind the Mississippi River) than any other river in the lower 48 states.In general, the Pacific Northwest has a wet and co ol climate which has led to the growth of extensive forests featuring some of the largest trees in the world. The regions coastal forests are considered temperate rainforests. More inland, however, the climate can be drier with more harsh winters and warmer summers. The economy of the Pacific Northwest is varied, but some of the worlds largest and most successful technology companies such as Microsoft, Intel, Expedia, and Amazon.com are located in the region.Aerospace is also an important industry in the Pacific Northwest as Boeing was founded in Seattle and currently  some of its operations  in the Seattle area. Air Canada has a large hub at the Vancouver International Airport.The Pacific Northwest is considered an educational center for both the United States and Canada as large universities such as the University of Washington, the University of Oregon and the University of British Columbia are located there.The dominant ethnic groups of the Pacific Northwest are Caucasian, Mexican and Chinese.

International Business - Culture Essay Example | Topics and Well Written Essays - 2250 words

International Business - Culture - Essay Example Social structures are values that were established long time ago. They define the organization of the society members into small units to meet necessities of the given society (Hyland 2012). The organization is mainly family and classes based. Social classes rank people in order of the important aspects like wealth, job, and education. In some societies, recruitments of people for jobs and promotions are based on competencies (Ajami & Goddard 2006). The contrast is based on sex, age, and family from which an individual come from. Different countries have different defined attitudes towards male and female as part of the social structure. This affects education and level of participation for the inferior gender. The inferior gender in most countries is that of women. Therefore, for a woman thinking of doing business in such environments will have to consider working with a male partner to act as the face of the business. This will increase cost of operation since the individual will have to be paid. Another factor to consider is Age. A country like Japan ascribes wisdom to be proportional to age (Ajami & Goddard 2006). Therefore, in this country, retirement for the old was not applicable which closed out young and energetic people for the opportunities. Another thing is family background of an individual. In some societies, for example Nigeria, a person’s effectiveness and acceptance is accepted or rejected based on the social status of the family from which the individual comes from (Aswathappa 2010). For the individuals coming from high profiled families, acceptance is not an issue as compared to the poor and low statured people.

She was able to make lots of sales and her expenses were only a little over half her revenue, which means that she made quite a substantial net profit. Wintz’ biggest expense was salaries, but even then this was only one-third of the net income. Other expenses, such as rent, supplies, and repair expenses, only cost a small portion of the total expenses. For the Retained Earnings Statement, Wintz was able to make back more than double her initial investment. For a business that was only open for four months, this is very impressive. Wintz also paid out some dividends to shareholders, but there was still enough retained earnings left at the end of August that Wintz could return to college feeling satisfied with her summer’s work. For the balance sheets, th e assets column looks very healthy. Added to this is the fact that there are very few liabilities, which means that the business does not have any worries.

Gender representations in The Big Bang Theory Essay

Gender representations in The Big Bang Theory - Essay Example This study aims at giving insight on how the use of gender representation is utilized in The Big Bang Theory to attract a large audience. As indicated by the title, this project explores the gender representations in The Big Bang Theory. There have been other studies about this subject too. However, what makes The Big Bang Theory a classical study is the controversial sexist position it adapts. This is the reason why this research aims at conducting a scientific inquiry on the unbalanced gender portrayal. One of the sets of questions that urgently require addressing is the relationship of discourses of gender in the media. For instance, what contributes to the popularity of The Big Bang Theory show notwithstanding the unsurpassed gender misrepresentation overriding in the show? This study will compare, contrast, investigate, examine, develop, and evaluate the subject matter. An proper indulgent of the facts contributing to the popularity of the show is quite significant as it would i ndicate the exact reasons as to why the various attempts to fight for egalitarianism have never been prolific. . It is beneficial to gain an appreciation regarding gender representations, the values and ideologies presented in The Big Bang Theory as this might aid in formulation and implementation of effective policies to circumvent the menace, change people’s psychological perspectives on gender and improve societal welfare and amalgamation.

Food Processing Technology and Methods for Cereal

Food Processing Technology and Methods for Cereal Most of the principles of making breakfast cereals are similar to all products. Trix cereal is made with corn. The process of converting corn into the delicious product many children as well as adults will be discussed in this section. The corn from the field is dried milled, sifted and cleaned to separate the germ from the bran, oils and debris collected from the field and the milling process. The goal of this separation is to get to the endosperm where most of the starch that will be used for production is located. Most cereals produced are produced as flakes. Prior to flaking the grits are cooked and mixed with sugar, malt syrup, proteins, and salt into a large amount of water to create what is called cooking liquor. This cooking liquor provides the Milliard reaction that occurs during cooking and is what provides most of the flavor to the flakes or in the case of Trix, corn puffs. This mixture is loaded into a cylindrical industrial steam pressure cooker for about two hours at a 15-18 psig steam pressure (Smith Hui, 2004). In the case of Trix the cooking process is done by puffing. Puffing is done either through high temperature ovens, guns or extrusion. The use of any of these three methods is to expose the moist grain to high temperatures where its moisture will be converted to steam. The steam released by the grain expands and puffs the kernel. Prior to placing the grits into any of these three methods, the grains are delumped in lump-breaking machines which incorporate large volumes of air. The air supplied through the machine helps with the cooling of the product. The cooling of the grit in the lump-breaking machine helps with the initial drying step of the process of making ready to eat cereal. Grits usually have a moisture content of 28-34% (Smith Hui, 2004) are dried to about 14-17% through the use of forced air dryers at a temperature of 250 °F (Smith Hui, 2004). Once the grains have gone through this initial drying, the grains are controlled cooled to 100 °F to prevent hardening of the grain and to allow the grain to return to ambient temperature. (Smith Hui, 2004). Once the grain is dried to the moisture levels desired, the grain is tempered. Tempering of the grits takes about 2-3hours, helps reduce the darkening the product that occurs during Milliard reactions, and allow the grit to retrograde. This process uses temperature of 80o F and increases the firmness of the cooked grit (Smith Hui, 2004). From this point the grit is ready for flaking, shredding, or any of the methods of puffing grits. General Mills utilizes puffing guns to make Trix cereals. The science behind the puffing gun utilized by General Mills and some of its competitors, works by introducing the grains to high (500-800  °Ã‚  F) temperatures. This high temperature evaporates the moisture within the granules creating a steam pressure build up (100 to 200 psi) inside the chamber. When this pressure is released the moisture attempting to escape the grain, causes the endosperm to expand and simultaneously puff. Puffing guns have come long ways from when they were first introduced in the cereal business. Today General Mills utilizes a continuous puffing gun systems and extrusion puffing. Continuous puffing guns work the same way as it predecessors. The continuous gun contains a rotating cylinder that is set a specific angle. The cylinder is heated either by gas flames or electrically, and it is fed through a rotary valve. The pressure in the cylinder remains constant via the exit, thus continuously discharging the product. The contents explode into a bin provided with a floor opening leading to a conveyor belt. The product is directed to a rotating heating cylinder to dry, and then cooled. At this point the product is visually inspected for stickiness and color and sent to the packaging line. Direct expansion or extrusion puffing is the other method used by many cereal manufacturers. This type of technology was received with open arms by the cereal industry because it allows the combination of the steps in the process into one. Cereals ingredients are introduced in one batch into long barrels equipped with single or twin screws. The screws mix, shear, and pressurize the barrel and transport the â€Å"dough† to a forming die. As the mixture flows through the extruder, vitamins, flavors and colors are introduced and then the mixture exits through the die. The same principle of the puffing gun is applied to extruders. As the moisture vapor expands and the excess pressure is released, the volume of the mixture increases. The temperature in the barrel increases the mixture to about 300o-350 o F and the pressure to about 350-500 psi at the die head. As the dough exits through the orifices of the die, it is sliced off in to the different shapes and the slices expand immediately. Despite this quick expansion, the pieces still maintain moisture content of about 27% and are further dried on vibrating screens in hot air puffing ovens where the final cooking of the product occurs (Smith Hui, 2004). Pieces are inspected and sent to the packaging line. Although extruded and gun puffed mixtures products are enriched and fortified during the cooking process, the puffs receive a final spray of vitamins, sugar and flavors inside rotating spray drums. Both final sprays assist with the reduction of lipid oxidation and moisture which improve the overal l quality of the product as it relates to its texture and crispiness. One aspect of producing cereal is its quality. The cereal industry uses multiple methods to assess the quality of its product during the production process. The biggest issue for a good cereal product is moisture. Moisture is measured through near infrared analysis (NIR), wet chemistry, and image analysis. During the process the product the raw material is analyzed for moisture to ensure it can be flaked, shredded, shaped, maintained for control of oven temperatures, and to control the sugar content applied to the product. This type of testing can also be done to the final product where the fat, sugar, and moisture are analyzed to ensure the operation is working at optimum conditions. These test is necessary due to any unacceptable moisture content could lead to poor product quality as well as possible bacteria growth. At present, cereal industries are performing little or no analytical testing, and are relying on the vendors to provide them with highest quality level of product for their market. This can present a problem in production process. Despite the fact that the cereal industry does little or no analytical testing, most of the moisture content testing is performed as the product exits the oven using a 16 hour vacuum oven method or a moisture balance method (Unity Scientific, 2014). According to Unity Scientific, â€Å"both methods use loss on drying to measure moisture content.† The main problem with the 16 hr oven method is the time it takes to get results, and when these are received they â€Å"have no impact on real time process control† (Unity Scientific, 2014). When it comes to the moisture balance method Unity Scientific says, although the sample can be â€Å"analyzed in 15 minutes it is â€Å"2-3 times less accurate the vacumm oven method.† The key to cereals i s the control of its moisture and texture. Moisture as mentioned previously, is critical to maintaining a cereal’s integrity, and it is crucial that the moisture of a cereal product is not greater than 3%. Anything less or greater could reduce its crunchiness as well as make it brittle. Therefore, NIR is one of the best methods of testing for moisture as well as fat content in any step of the process. In regards to its crunchiness the cereal industry uses mechanical as well as sensory evaluation methods to ensure the products texture. Nonetheless, sensory evaluations can be subjective. One of the best ways to analyze texture is the use of mechanical instruments as these provide a quantitative measure of texture. Currently instruments used by the cereal industry include Stevens, Instron and Ottawa Texture Analyzer. The purpose of these crunch evaluation methods is to find the bowl life by exposing the product to milk for a small period of time and then performing a shear test. Other equipments used are the multiple crunching probes and the Ottawa Cell shearing test. The final step in the production process is packaging. Different equipment and films are used across the board in the cereal industry. Some of the machinery used include Ishida multi-head weighers, Bosch vertical form fill seal machines and Triangle bag in box packaging. When it comes to films, they either use wax paper or various polymer films (Smith Hui, 2014). However, before selecting a packaging film, cereal manufacturers consider whether the location the product is going to be sold is humid or arid. Based on these conditions the film is selected and used for production. One of most common packaging materials used in the cereal industry is polyethylene films (Smith Hui, 2014). The packaging film must protect from water vapor transmission and flavor loss. As mentioned previously, moisture plays a big role in the process and any sign of moisture gain could lead to potential loss of crispiness and acceptability of the product. Another issue for cereals is the instability of lipid s. Lipid oxidation leads to rancidity thus, creating a bad aroma in the product. To prevent lipid oxidation and moisture gain in the product, the cereal industry utilizes different antioxidants. The antioxidants commonly used are butylated hydroxyanisole (BHA) and butylated hydrooxytoluene (BHT) (Smith Hui, 2004). Although their use is limited in the production process, these can be added before cooking. However, after several trials, it was discovered that due to their non polarity and their volatility these would not hold during the manufacturing process. Nonetheless, it was discovered it was better to apply these antioxidants to the packaging material as the antioxidants would transfer to product after packaging (Smith Hui, 2014). Packaging does more than protect from decay, it provides the identification, and it provides consumer attraction and appeal to the product. Producing cereals entails more than what is see in the grocery store shelves or what is consumed at homes. Essentially behind all of this manufacturing process is the effort to make profit, but no matter what idea the manufacturer may have, protecting the product and providing the best quality of product to consumer becomes primordial. Accurate shelf lives, quality of stored cereal, its freshness are what attract and appeal the consumer. References How Products Are Made. Cereal. 2014.

Ritalin: Abuse Essay -- essays research papers

Ritalin: A Miracle Drug, or Another Cocaine?   Ã‚  Ã‚  Ã‚  Ã‚  If the term â€Å"Attention Deficit Hyperactivity Disorder†(ADHD) is mentioned, the first thing that comes to many people’s minds is a drug called Methylphenidate, commonly referred to as â€Å"Ritalin†. Most people know Ritalin is prescribed for ADHD, and they most likely know at least one person who is currently taking it. However, in the 1960s, Ritalin and many other amphetamines were recognized as abusive substances, so many new controls were introduced to more closely monitor the prescribing of these drugs. Despite these new restrictions, the abuse and over-prescribing of Ritalin has re-emerged from the shadows.   Ã‚  Ã‚  Ã‚  Ã‚  One way the over-prescribing of Ritalin has emerged is its constant use for treating ADHD in children and adolescents. ADHD is a behavioral disorder and generally infects boys between the ages of six and fourteen (United Nations Warning on Ritalin, 1). Data shows that 10-12% of all boys in this range are taking Ritalin for the treatment of diagnosed ADHD. Since 1990, the number of people taking Ritalin has increased by 500%. As of now, the United States has the highest level of Ritalin use and production. Canada uses just under half of what the U.S. uses of Ritalin and no other countries have come close. 7-10% of the U.S.’s boys are on this drug, which is an overwhelming number compared to other countries around the world. As a result of this, the gover...

Man’s Flaw in War of the Worlds and Present Day Earth Essay

An interesting quote taken from Kepler starts out the book War of the Worlds by H. G. Wells: But who shall dwell in these worlds if they be inhabited?†¦ Are we or they the Lords of the World?†¦ And how are all things made for man? (Kepler, the Anatomy of Melancholy). This quote serves as a foreshadowing to what Wells considers to be man’s fundamental flaw, a flaw that still exists today on modern man, more than a century after War of the Worlds’s first publication and centuries more after Kepler’s time. According to Wells’s introduction, man’s first fundamental flaw is complacency â€Å"With infinite complacency men went to and fro over this glove about their little affairs, serene in their assurance of their empire over matter† (Chapter 1, p. 3). In War of the Worlds, man thought that they are the only inhabitants of the universe and remain complacent over the dangers that might be coming from places other than what they can comprehend. Little did they know that they are being watched by creatures from space just like how a scientist examines a microscopic organism under a microscope. Unfortunately today, man still suffers from this complacency. We have abused nature for the longest time thinking that its resources and its tolerance to our actions are boundless. Now, we are facing the ill effects of our wrong doings, our resources are dwindling, and our climate is rapidly changing. Vanity is the next flaw that Wells talk about in his introduction of the book. â€Å"Yet so vain is man, and so blinded by his vanity, that no writer, up to the very end of the nineteenth century expressed any idea that life might have developed there far† (Chapter 1, p. 4). Man became too preoccupied with his achievements that he hadn’t put it into thought that Mars is older than Earth and therefore could be more advanced than humans if indeed there is life on the red planet. Vanity is one of the oldest flaws of man, the Greeks shows this flaw perfectly through the myth of Narcissus, a mythological character whose name means self-admirer. Vanity is still among man’s flaw today, some people are so vain that they are willing to spend ridiculous amounts of money on cosmetics. They could have just used the money on other necessary things or better yet, to help the needy. Last is man’s flaw for being judgmental. â€Å"And before we judge them too harshly we must remember what ruthless and utter destruction our own species has wrought† (Chapter 1, p. 6). Wells questions that the Martians’s intent to take over the earth isn’t any different than what the humans has done over animals and even our own species. The same could still be applied today. Man by virtue, does not have the right to complain if indeed Martians invade the earth and do all those things that we do to our animals. In the book, Martians are just doing what they can do to survive, but man (in the real world) harms creatures even if it is not necessary for survival. All these flaws can be summed up to pride. In ancient Greek literature pride or hubris as they call it, is the fundamental flaw of man that causes his demise. Kepler and Wells advocate the same thing in their works

Holiday Sales May Be Frightful Essay

The article â€Å"Holiday Sales May Be Frightful, But Discounts Will Be Delightful† discusses tough holiday season for retailers because Christmas sales are expected to increased up to 4%. Nevertheless, the season is claimed to be soft and sluggish. This season is, actually, slower compared with sales of the previous year. The decrease in sales is explained by macroeconomic problems as, for example, house slump and credit crunches which negatively affect customers. The author cites Niemira who argues that â€Å"a huge worry facing the holiday season is that the home-price decline and housing wealth decline will cut into consumer spending broadly†. I think the article is informative and provides up-to-date information as practically all people are interested in making purchases. It is known that one of the most popular leisure activities in American consumer is shopping. People are ready to spend money on things they are willing to possess, but housing problems make it less affordable for many citizens. All aspects of consumerism are paid thorough attention by marketing workers and economic analysts. I think the author is very logical and unbiased as the author firstly defines the problem and then explains what reasons have led to it. Credit crunch and housing problem, in my opinion, are two the most serious problems. For example, the author says: â€Å"the credit crunch makes it harder for all households, especially low-income families, to refinance and get other credit†. Apparently, the poor have been disproportionately hurt by high fuel prices. I think that the author does sense in his argument and suggestions. Moreover, all his ideas are properly supported by evidence and explanations of analysis and economists.

Definition and Examples of a Grammatical Category

Definition and Examples of a Grammatical Category A grammatical category is a class of units (such as noun and verb) or features (such as number and case) that share a common set of characteristics. They are the building blocks of language, allowing us to communicate with one another. There are no hard and fast rules for what defines these shared traits, however, making it difficult for linguists to agree on precisely what is and is not a grammatical category. As the linguist and author R.L. Trask put it, the term category in linguistics is so varied that no general definition is possible; in practice, a category is simply any class of related grammatical objects which someone wants to consider. That said, there are some strategies you can use to group words into categories based on how they function in the English language (think of parts of speech). Identifying Grammar Groups One of the simplest ways to create grammatical categories is by grouping words together based on their class. Classes are word sets that display the same formal properties, such as inflection or verb tense. Put another way, grammatical categories can be defined as sets of words with similar meanings (called semantics). There are two families of classes, lexical and functional. Nouns, verbs, adjectives, adverbs, and adjectives fall into this class. Determiners, particles, prepositions, and other words denoting position or spatial relationships are part of the functional class. Using this definition, you can create grammatical categories like this:   Verbs denote actions (go, destroy, buy, eat,  etc.)Nouns denote entities (car, cat, hill, John,  etc.)Adjectives  denote states (ill, happy, rich,  etc.)Adverbs  denote manner (badly, slowly, painfully, cynically,  etc.)Prepositions  denote location (under, over, outside, in, on,  etc.) Grammar groups can be further divided, depending on a words defining properties. Nouns, for instance, can be further subdivided into  number,  gender,  case, and  countability. Verbs can be  subdivided  by tense,  aspect, or  voice. Grammar Tips Unless youre a linguist, you probably wont spend much time thinking about how words can be classified based on how they function in the English language. But just about anyone can identify basic parts of speech. Be careful, though. Some words have multiple functions, such watch, which can function as both a verb (Watch out over there!) and a noun (My watch is broken.). Other words, such as gerunds, may appear to be one part of speech (a verb) and yet function differently (as a noun). In these cases, youll need to pay close attention to the context in which such words are used in writing or speech. Sources David Crystal,  A Dictionary of Linguistics and Phonetics, 4th ed.

Ethics and the Role of Nurses Article Example | Topics and Well Written Essays - 750 words - 1

Ethics and the Role of Nurses - Article Example This group of professionals is required to make critical and delicate decisions in the performance of their day to day duties. The decision s they make in most cases determine the care or treatment a patient is going to receive, hence, they determine the final outcome of the treatment process. The making of the right decisions is an action that strongly requires the application of ethics (Butts & Rich, 2013). It is true that by understanding one’s own ethical behavior, one is able to through the professional assessment; one is able to know and understand those of others. This makes it important for nurses to understand their ethical behavior not just in terms of their relationship with patients, but also with that of colleagues, employers, and junior staff as well as the community. According to Guido (2006), understanding the importance of ethics is a crucial component of specialized health care delivery. Ethics makes part of every aspect of nursing and nursing care. For nurses to be able to act according to the expected ethical standards there is need for them to analyze and comprehend the various ways through which they can assess ethical behavior (Butts & Rich, 2013). This view is further supported by Chaloner (2007) who is of the opinion that it is important for individual health care givers and teams to perform an ethical analysis, based on their knowledge, skills and experience, in their continuous professional practice. This according to the author is an important element to an informed process of making decisions. The ethics self assessment is one important way through which one can identify the various ethics. It was therefore a right choice of means for you to assess your ethical behavior. It is true that through the assessment one can be able to identify one’s strengths and weaknesses and as a result be able to identify the various areas that need improvement.
