Juvenile Justice - Essay Example Juvenile court proceedings were not open to the public and were left to the discretion of the juvenile court judge. Records were confidential to protect the juvenile’s privacy and promote his/her chances for rehabilitation, reuniting with family and rejoining into society. Because of some tensions, such as concentration on the juvenile’s welfare against concentration on his/her incapacities, deserved punishment, and the protection of society from the juvenile’s misdemeanors; different juvenile justice systems were established in every state and jurisdiction (McCord, Widom & Crowell 154). All systems of the states of California, North Dakota and South Carolina have the same goal: the treatment and rehabilitation of young delinquents. Shown in this paper are similar or different ways of addressing juvenile crimes in these states. In California, juveniles age 17-24 years old are detained for infringements of court orders; evasion from obligation; if the juvenile has a possibility to escape; for the protection of the juvenile or society; and if the juvenile is incriminated in certain felonies. As a disposition or as a sanction for breach of trial, aside from holding young offenders in protected detention before juvenile court judgment, sentencing, disposition and consignment, a court may take a delinquent to a juvenile hall, foster care or group care; or released to parents for home confinement. In North Dakota, 17-20 year-old offenders are held in detention for his or society’s protection; if there is a possibility of escape or from being removed from court rule; in cases when the offender has no parent or guardian; or in cases when the juvenile court has issued a detention order. The state’s detention is given in 7 regional juvenile detention centers managed by the county or associations of var ious counties, or by the North Dakota Division of Juvenile Services provided at the Youth Correctional Center.

Transmission of Sound Waves in Ocean Water Essay Example for Free

Transmission of Sound Waves in Ocean Water Essay Ocean acoustics is the study of the behavior of sound in the sea water. When underwater species and objects move and vibrate, they create sound-pressure waves which compress and decompress water molecules. These sound waves travel through the sea and radiates in all directions away from their source and thus forming ripples on the water surface. The three basic components of sound waves which explain the behavior of sounds are wavelength, frequency and amplitude. Frequency is the number of pressure waves that pass by a reference point per unit time (NOAA Ocean Explorer). Higher frequency means a higher pitched sound and vice versa. Wavelength is the distances between the two peaks of sound waves. It is a rule that longer wavelength means lower frequency. Lastly, amplitude is the height of the sound-pressure wave or it is the loudness of a sound (measured in decibels). If there are only small variations in amplitude (short pressure waves), the sound is said to be weak or quiet, and vice versa. Temperature, pressure and the degree of salinity also affect the speed of sound. The spread of sound waves in sea water can be directly affected by suspensions of particle matter that can scatter, absorb and reflect waves. This means that the more obstructions there are beneath the water, the more random sound waves can be. It has been proven that wavelength and frequency are inversely proportional (i. e. the longer the wavelength, the lower the frequency). When long wavelength sounds encountered few particles as they pass through the medium, they are not as subject to absorption, reflection or scattering. Therefore, low frequency sounds are able to travel farther without any significant loss of signal strength. The speed of sound in the deeper regions is influenced more by high pressure than any other factors. On the other hand, temperature is the factor that governs the speed of sound in shallower surfaces. In short, the greater the temperature of water the faster sound can travel and the greater the pressure, the slower the sound can travel.

Cow disaster :: essays research papers

OTTAWA (CP) - Canada's $8-billion mad cow disaster can be squarely attributed the failure of the Canadian Food Inspection Agency to assess economic consequences of even a single infection, says a leading expert. ADVERTISEMENT I'm a WomanMan seeking a ManWoman Age: to Postal Code: William Leiss of the University of Ottawa, who is also a past president of the Royal Society of Canada, said the CFIA assessed the risk of mad cow to animal health and human health, but not the risk of losing export markets. Yet Canada was party to an international agreement providing for a ban on exports from any country with even a single case of the disease. The policy was known as "one cow and you're out." "What would be the economic impact of one or just a few cases of BSE (bovine spongiform encepalopathy) in the Canadian herd?" Leiss asked at a World Health Organization conference on risk management. "We failed completely to manage or even to recognize this risk at our great cost." He said Canada followed U.S. policies in adopting a minimal testing program. But Canada's risk profile is completely different from that of the United States. At the time, Canada exported 75 per cent of beef production while the United States exported only 10 per cent. Losing export markets was not a serious problem for the Americans, he said. "In food issues we are cursed with the political attitude that we've just got to be onside with the U.S. and nothing else matters." He said the CFIA also followed the U.S. lead in making a half-hearted effort to stop recycling infected protein in ruminant food, which is widely believed to be the cause of mad cow disease. Leiss said the CFIA ban on feeding proteins from ruminants to ruminants remains "full of holes." Leiss said the United States conducted a full risk assessment in 1997-98, but Canada did not do one until six years later. CFIA spokesman Marc Richard said the agency didn't include economic consequences in its assessment because that is not the agency's mandate. "We don't usually address the economic stuff," said Richard in an interview. "The risk assessment was based strictly on the disease. Overall we're the administrators of the Animal Health Act. "The CFIA's risk assessments have to do with animal disease. That is our mandate and in our mandate we specifically don't address economics." But another CFIA official, senior veterinarian Darcy Undseth, said economic consequences of a mad cow infection in Canada were considered in a 2002 risk assessment even though they were not quantified.

Cell Phones: The Good, The Bad, and The Ugly

The prevalence of cell phones in American culture shouldn't come as much of a surprise to anyone. Cell phone use has risen In the united States from approximately 91,000 users 985 to In 2007 and n 2009 was somewhere In the neighborhood of 280,000,000, which means that approximately 90% of Americans own cell phones. And Americans arena the only ones. According to a February 2010 article on www. Cobwebs. Com, there are approximately 4. 6 billion cell phone subscriptions worldwide and that number is expected to surpass five billion by the end of the year.I had to wonder, what are the advantages and disadvantages of 90% of Americans (New York Times, May 13, 2010) and nearly 85% of the world's population using cell phones? I figure there had to be quite a few advantages for so many people to have cell phones, so I asked around. The number one answer I found was the convenience. Peoples' ability to be reached at all times, able to reach others at all times, and how fast communication with others has become. Can't reach someone by phone? Send a text. Text messages are delivered almost Instantaneously and there's no need to eave a message and Walt for a call back anymore.Many others cited having a cell phone In case of emergency. According to Pew Internet, In 2006, 74% of cell phone users reported using their cell phones in emergency situations. While cell phone bills are usually not lower than landlines bills alone, the long distance cost is significantly less for cell phone users. Long distance costs are included in the overall minute usage for most cell phone subscriptions, whereas many landlines providers charge by the minute for long distance calls. As cell phone technology advances, so o the tools available to cell phone users.A growing number of users report using their phones for such things as listening to music, checking email, keeping their daily calendars, making grocery lists, and even keeping track of daily calorie intake. (New York Times, May 13, 2010). There are many organizational tools available on the new generation of â€Å"smart phones† as well as many different navigational tools. GAPS locators In phones are subscribed to by many parents of underage cell phone users. Cell phones can also be used as cameras and video recorders and those photos and ideas are easily emailed to others or uploaded to sites such as Twitter and Faceable.Entertainment is even making the list of advantages to having a cell phone these days. As I mentioned previously, users can listen to music on their cell phones, but it doesn't stop there. Technology has advanced so much that users can now watch television shows and movies on their phones. So it seems I was correct about how many advantages must be out there, but what about the downside? The very first thought I had was about the ban on cell phones in schools and what a huge disruption cell phones must be In the classroom. That issue Is Just part of the larger issue of the widespread distract ion cell phones cause.Everywhere you go you see cell phones In use – In the coffee shop, the movie theater, the grocery store, even church, and while driving. Going back to the cost of cell phones, while heavy long distance users may notice a relief in their long distance landlines. There are costs for air time usage, text message usage, broadband usage, music purchases, games purchases, and app purchases, not to mention the dreaded overage costs. Some cell phone companies charge as much as sixty cents per minute or every minute of air time over your allotted plan.Add that to long contracts and hefty fees for canceling contracts and cell phones become quite an expensive venture. The ever-increasing technology is adding to these costs as well. Newer, smarter phones released every few months are of course attractive to users, but on top of the cost of upgrading phones on a regular basis is the added cost of the service provider's data package. In order to utilize these newer sm art phones, the data package is a requirement and on average costs something like an additional $30 ere month. Aside from financial impact, what about health impact?There seems to be quite a bit of worry over the radio frequency radiation given off by cell phones and cell phone towers. There is much argument about whether or not this sort of radiation is of any real concern, but according to www. Contemporaries. Com, there are many very serious health concerns to think about. There are reports that cell phone use can cause disturbances in sleep and concentration, fatigue, and headache. According to a BBC News report (wry. News. BBC. Co. UK), â€Å"Cell phones image key brain cells and could trigger the early onset of Alchemist's disease †¦Researchers have found that radiation from cell phone handsets damages areas of the brain associated with learning, memory and movement. † Reports linking cell phones to sterility in men, eye tissue damage, and increased chances of depr ession and cancer have also been published. In researching the negative effects of cell phones, I happened across some even more sinister effects. Take â€Å"setting† – â€Å"the act of sending, receiving, or forwarding sexually explicit messages, photos, or images via cell phone, computer, or other chital device.These messages, photos, and images are then often being further disseminated through email and internet-based social networking websites well beyond their original intended recipients. † (wry. Mass. Gob) There have been hundreds of reported cases of setting – a handful of those cases involving suicide and/or sex offense criminal charges such as child pornography in the cases involving high school students. According to www. Masc.. Com, 39% of high schools students admit to sending these types of messages and 48% say they've received them.Another very dangerous habit Americans have developed is talking on their cell phone while driving. Muff have four times the risk of being in a crash if you're on the phone while driving. † (www. Unfathomable. Com) What's even scarier are the results of a Car and Driver Magazine study that found testing while driving is much worse than driving while intoxicated. The results of this study showed that unimpaired, it took the test driver . 54 seconds to brake when indicated to do so. Add four feet to that time for legally drunk drivers, thirty six feet for drivers reading email and events feet for drivers reading a text. Http://www. Zinc. Com/id/31 545004/site/ 14081 545). According too report by the National Safety Council, 28% of accidents involve talking or testing on cell phones. I couldn't help but notice that the risks seem to outweigh the benefits considerably, but I also admit that I'm still addicted to my cell phone. There has been their use elsewhere and I think there needs to be much more, although, I'm not certain how feasible that would be to accomplish. At any rate, we all make our own choices and we all need to make smarter choices about our cell phone use.

Leonardo da Vinci’s †The Last Supper Essay

The Last Supper is a unique painting. One of the reasons it is so different is that the canvas it is painted on is much wider than it is tall. By looking at the painting you can see that da Vinci is painting a gathering of people with the one in the middle of the table receiving most of the attention. The painting is most likely done on a canvas with simple oil paints. One feature a viewer might notice is Leonardo’s use of rectangles. Whether this is intentional or serves any purpose is unclear, but other than the humans in the scene everything is a rectangular shape. The work is organized with all of the focus of the viewer falling on the meal, or even more specifically on the man in the middle. da Vinci draws us to this man because he has placed three windows as a source of light in the background. The windows are directly behind him, drawing our attention to the contrast between the two. The viewer may also notice that all of the characters around the focal point lean slightly in one direction or another, while the character we are intended to focus on remains erect. The artist is conveying the message that something has shocked the men around this, one. One can assume that it may be surprising news or something to that extent. However, since this is a well-known painting there are not many that don’t know what it is actually about. The painting of â€Å"The Last Supper† is Leonardo da Vinci’s portrayal of Jesus’ last meal with his disciples. That night Jesus would tell the disciples that later one of them would betray him. Jesus’ honesty and forwardness shocked the disciples, and in turn they all began to question themselves. In da Vinci’s masterpiece one can see that perhaps Jesus has just delivered this message and that the disciples are taken aback by his accusation. In my opinion this painting lives up to its hype. The artistry is pure genius. Leonardo da Vinci makes the viewer see exactly what he wants them to see. The focus is all on Jesus, but if you take the time to look at each disciple you can almost feel what they are feeling. The crowd at the table appears much like a lunchroom rumor fluttering about a high school  cafeteria. The way Jesus lays his hands on the table is symbolic. His palms turned upwards toward the heavens with his arms fully extended, yet dropped heavily onto the table. Jesus is offering himself up, da Vinci captures the moment perfectly.

Essay Sample on Proteomics What is the Interest for Researchers

Essay Sample on Proteomics What is the Interest for Researchers Proteins are a basic building block of life on earth. They are the molecules that provide structure, produce energy, and allow communication, movement and reproduction within a cell. They, along with carbohydrates, amino acids, and phospholipids, are the key macromolecules that make up organisms. The body of proteins that make up an organism is referred to as its proteome. Proteomics is the study of these proteomes, including the identification of the proteins and their physiological functions. The study of proteomics had declined in recent years, but the inception of the Human Genome Project ten years ago revived interest for many researchers. Since then, the proteomes of numerous organisms have been determined. The Human Genome Project determined that the human body contains 30,000 genes. This translates to anywhere from 300,000 to one million possible proteins. The importance of proteomics largely lies in drug design and synthesis. Hopefully, new disease markers and drug targets can be identified that will help design products to prevent, diagnose and treat disease. This cannot be accomplished without knowledge of the proteome, however. A protein is a biological polymer that usually consists of hundreds of amino acid monomers. The general structure of an amino acid is a carbon atom to which four functional groups are bonded. Three of the groups include a hydrogen atom, an amine group, and a carboxylic acid group. The fourth group, or ‘R’ group, is a hydrocarbon chain. This R group is unique to each particular amino acid and is what determines one amino acid from another. The primary structure of a protein is its linear sequence of amino acids bound by peptide bonds between a nitrogen atom of one monomer and a carbon atom of another. Disulfide bonds between cysteine residues within the molecule stabilize it. This structure determines the secondary, tertiary, and quaternary structures of the protein as well. Proteins are highly specialized, and a single change in an amino acid monomer can result in a completely different function, or no function at all for the protein. Thus, the primary structure is of utmost importance. The secondary structure of proteins consists of the primary structure formed into two possible regular structures. These are an alpha helix or a pleated sheet. These structures can organize themselves in a repeating fashion or randomly. Disulfide bonds determine the secondary structure, while hydrogen bonding also stabilizes the conformation. A protein’s tertiary structure is the overall 3-D configuration of the complete protein. Amino acid residues that are far apart in a primary structure can have steric relationships in 3-D form, and the tertiary structure considers this. The tertiary structure is the most thermodynamically stable for the protein in a certain environment; it can change with environmental changes. This is how proteins are denatured. A protein may consist of several subunits. The quaternary structure of a protein is made up of all of these subunits bound together by electrostatic and hydrogen bonds. Multisubunit proteins are called oligomers and all of the component parts are monomers or subunits. Proteins may also contain non-amino acid functional structures such as a lipid or a carbohydrate. In order for proteins to be studied, they must first be isolated. In one dimension, the proteins are separated by charge based on their isoelectric points. The migration of different proteins in an electrically charged environment of graduated pH can separate them when their isoelectric points are different. The proteins move toward the pH at which they have no net charge. The main way this has been achieved is through 2-D polyacrylamide gel electrophoresis, or 2-D PAGE. This experiment can achieve the separation of several thousand different proteins in one gel, while high resolution 2-D PAGE can resolve up to 10,000 proteins per gel. Coomassie blue, silver, and SYPRO Ruby Red stains are typically used to visualize the proteins’ migrations. Mass spectrometry is a technique used for the determination of the mass of a compound; however, it is also useful in protein identification. The spectrometer ionizes the protein, and this charged molecule is sent into an analyzer on the basis of charge repulsion. This analyzer resolves the proteins based on their mass to charge ratio, thus separating them. The detector passes the information to the computer for analysis and identification. Fragmentation can cause problems in protein separation, so ionization methods that minimize formation of fragments are most useful. These methods include matrix-assisted laser desorption/ ionization, or MALDI and electrospray ionization, or ESI. Once a protein has been isolated, its structure must be determined. Secondary and tertiary protein structures can be found by two methods: X-ray crystallography and nuclear magnetic resonance. Both methods require that the protein be better than 95% pure for the best results, so the isolation methods are extremely important. The experimental technique can include gel or column separation, dialysis, differential centrifugation, salting out, or HPLC. The choice and order of experiments is modified to suit the protein of interest. In order to study a protein’s structure through X-ray crystallography, it must be crystallized. The most common methods of crystallization are batch methods and vapor diffusion. A supersaturated solution is formed which causes the protein to associate with other protein molecules. The formation of this solution often requires the addition of precipitants such as polyethylene glycol or certain salts. The identification of the amino acids in the protein are again important here, since they can determine the exact reagents and chemical and physical conditions used to crystallize the protein. The crystals are then mouted and snap frozen. This is accomplished by exposing them to cryogenic liquid or gas. In X-ray crystallography, the crystals are subjected to X-rays containing a heavy metal atom. This method can determine the protein’s secondary and tertiary structure. The X-rays are scattered by the crystal in a pattern unique to the protein. One drawback is that the radiation can damage or backscatter; keeping the crystals supercooled minimizes this side effect and allows the crystals to be stored and reused. A model of the protein is then constructed using the data translated into electron density maps. This method is highly important in drug design, since it is very precise and can reveal crucial structural data. Nuclear magnetic resonance, or NMR, spectroscopy involves the alignment of nuclear dipoles of a sample in a magnetic field. These dipoles can change orientation back and forth in a magnetic field and absorb and emit energy for each turn. The spectrometer contains an antenna within the magnet; radio waves are pulsed by this antenna through the magnet. The sample absorbs these pulses as energy and then emits them sometime later. This time is measured and stored on the computer. Most often, pulse sequences are used that take advantage of the strong nuclear dipole of the hydrogen nucleus. The information gained from this experiment allows researchers to map the chemical bond connectivity and the spatial orientation of the proteins. This method is particularly useful in determining the function of active sites on enzymes. NMR spectroscopy has several advantages over X-ray crystallography. One is that NMR requires no crystallization in order for the protein’s structure to be studied. Currently, this method can resolve proteins with molecular weights up to 30,000 Daltons; it is predicted that structures with molecular weights of up to 100,000 Daltons can soon be determined through this method in the coming years. Another advantage is that NMR is sensitive to motions on the millisecond to second range, which can be directly studied. Even motions as small as those of the nanosecond to microsecond scale can be studied indirectly. X-ray crystallography is also an extremely time-consuming process, and the crystalline structures can be difficult to maintain. However, the greatest advantage of NMR over X-ray crystallography is NMR’s ability to reveal the details of specific structural sites without solving the entire structure. Current studies in proteomics include the research being done by biochemists at the University of Washington in Seattle. These scientists are studying environmental effects on the transcription and translation of the mRNA molecule. This is the nucleic acid that codes for the manufacture of proteins within the cell. In an earlier study, they reported the use of Translational State Array Analysis, or TSAA. This method allowed for the simultaneous study of mRNA level and translation. They chose Saccharomyces cereviciae as their model and arrested it with the temperature-sensitive cdc 15-2 allele. A control was run in which forty-eight mRNA molecules changed upon release from arrest. However, when the temperature of the cdc 15-2 allele was lowered from 37 C to 25 C, fifty-four molecules of mRNA were affected. Therefore, regulating the translational level seems to affect directly the response of yeast cells to external cues. Another study done recently again involves the use of Saccharomyces cereviciae. This study, completed at Johns-Hopkins University, attempted to investigate whether indexing a proteome according to its C-terminal sequences could be of use in functional classification of proteins. The basis for this experiment is that the protein C-termini are capable of being recognition signatures for many biochemical processes. The extent to which carboxyl terminal sequences are conserved within the proteome is unknown, but this may be related to certain biological functions and therefore has great importance. The researchers analyzed the terminal sequences of Saccharomyces cereviciae and found that known and unknown terminal sequences existed. This result supports that there may be additional carboxyl terminal signals whose biological functions are not yet known.

History of St. Valentines Day in the 1800s

History of St. Valentines Day in the 1800s Commemorations of St. Valentine’s Day are rooted in the distant past. In the Middle Ages the tradition of choosing a romantic partner on that particular saints day began because it was believed that birds began mating on that day. Yet there doesnt seem to be any evidence that the historical Saint Valentine, an early Christian martyred by the Romans, had any connections to either birds or romance. In the 1800s, stories abounded that the roots of St. Valentine’s Day reached back to Rome and the festival of Lupercalia on the 15th of February, but modern scholars discount that idea. Despite the holidays mysterious and puzzling roots, it is obvious that people have observed St. Valentine’s Day for centuries. The famed London diarist Samuel Pepys mentioned observances of the day in the mid-1600s, complete with elaborate gift-giving among the wealthier members of society. The History of Valentine Cards It seems that the writing of special notes and letters for Valentine’s Day gained widespread popularity in the 1700s. At that time the romantic missives would have been handwritten, on ordinary writing paper. Papers made especially for Valentine greetings began to be marketed in the 1820s, and their use became fashionable in both Britain and the United States. In the 1840s, when postal rates in Britain became standardized, commercially produced Valentine cards began to grow in popularity. The cards were flat paper sheets, often printed with colored illustrations and embossed borders. The sheets, when folded and sealed with wax, could be mailed. The American Valentine Industry Began in New England According to legend, an English Valentine received by a woman in Massachusetts inspired the beginnings of the American Valentine industry. Esther A. Howland, a student at Mount Holyoke College in Massachusetts, began making Valentine cards after receiving a card produced by an English company. As her father was a stationer, she sold her cards in his store. The business grew, and she soon hired friends to help her make the cards. And as she attracted more business her hometown of Worcester, Massachusetts became the center of the American Valentine production. St. Valentines Day Became a Popular Holiday in America By the mid-1850s the sending of manufactured Valentine’s Day cards was popular enough that the New York Times published an editorial on February 14, 1856 sharply criticizing the practice: Our beaux and belles are satisfied with a few miserable lines, neatly written upon fine paper, or else they purchase a printed Valentine with verses ready made, some of which are costly, and many of which are cheap and indecent. In any case, whether decent or indecent, they only please the silly and give the vicious an opportunity to develop their propensities, and place them, anonymously, before the comparatively virtuous. The custom with us has no useful feature, and the sooner it is abolished the better. Despite the outrage from the editorial writer, the practice of sending Valentines continued to flourish throughout the mid-1800s. Popularity of the Valentine Card Boomed After the Civil War In the years following the Civil War, newspaper reports indicated that the practice of sending Valentines was actually growing. On February 4, 1867, the New York Times interviewed Mr. J.H. Hallett, who was identified as the â€Å"Superintendent of the Carrier Department of the City Post Office.† Mr. Hallett provided statistics which stated that in the year 1862 post offices in New York City had accepted 21,260 Valentines for delivery. The following next year showed a slight increase, but then in 1864 the number dropped to only 15,924. A huge change occurred in 1865, perhaps because the dark years of the Civil War were ending. New Yorkers mailed more than 66,000 Valentines in 1865, and more than 86,000 in 1866. The tradition of sending Valentine cards was turning into a big business. The February 1867 article in the New York Times reveals that some New Yorkers paid exorbitant prices for Valentines: It puzzles many to understand how one of these trifles can be gotten up in such shape as to make it sell for $100; but the fact is that even this figure is not by any means the limit of their price. There is a tradition that one of the Broadway dealers not many years ago disposed of no less than seven Valentines which cost $500 each, and it may be safely asserted that if any individual was so simple as to wish to expend ten times that sum upon one of these missives, some enterprising manufacturer would find a way to accommodate him. Valentine Cards Could Hold Lavish Gifts The newspaper explained that the most expensive Valentines actually held hidden treasures hidden inside the paper: Valentines of this class are not simply combinations of paper gorgeously gilded, carefully embossed and elaborately laced. To be sure they show paper lovers seated in paper grottoes, under paper roses, ambushed by paper cupids, and indulging in the luxury of paper kisses; but they also show something more attractive than these paper delights to the overjoyed receiver. Receptacles cunningly prepared may hide watches or other jewelry, and, of course, there is no limit to the lengths to which wealthy and foolish lovers may go. In the late 1860s, most Valentines were modestly priced, and targeted toward a mass audience. And many were designed for humorous effect, with caricatures of particular professions or ethnic groups. Indeed, many Valentines in the late 1800s were intended as jokes, and the sending of humorous cards was a fad for many years. Victorian Valentines Could Be Works of Art The legendary British illustrator of children’s books  Kate Greenaway designed Valentines in the late 1800s which were enormously popular. Her Valentine designs sold so well for the card publisher, Marcus Ward, that she was encouraged to design cards for other holidays. Some of Greenaway’s illustrations for Valentine cards were collected in a book published in 1876, ​Quiver of Love: A Collection of Valentines. By some accounts, the practice of sending Valentine cards fell off in the late 1800s, and only revived in the 1920s. But the holiday as we know it today firmly has its roots in the 1800s.
