Tv And Children Essays - Dispute Resolution, Crime, Criminology

Tv And Children Television Violence and Children Thanks to the miracle of television the average American child watches 8,000 murders and 100,000 acts of violence before finishing elementary school (Early Concerns 113). Television violence is responsible for the increase in childhood violence. Watching violence is a popular form of entertainment, and watching it on television is the number one way that children are exposed to violence. Local news shows provide extensive converage of violent crimes in order to increase their ratings (Felson 96). Violence usually refers to physical aggression and aggression is usually defined as any behavior involving intent to harm another person (Sege 34). Television is a central feature of contemporary American life. American children spend more time watching television than they do in school. In 1989, the average child in the United States spent more time watching television than performing any other activity, except sleeping. In 1989 The Nielson Report on Television commented that children age 2 to 5 viewed approximately 27 hours of television per week. Children 6 to 11 years of age viewed more than 23 hours of television per week, and adolescents between 12 to 17 years of age viewed 22 hours of television per week (Sege 32). During the past several decades, violent programs have been steadily increasing in numbers on television screens. Many believe that there could be the possibility that a direct relationship exists between the violence witnessed on television and the increasingly violent behavior of children and adolescents (Palermo 23). Coming at a time when the homicide rate is rising six times faster than the population it is theorized that television violence does cause actual violence (Early Concerns 114). The year 1992 set an all-time record for violence in childrens shows, with an average of 32 violent acts per hour. The nightly dose of splattering blood, rapes, car wrecks and screaming victims on television has tripled in the last decade (Johnson 18). Only on television is there violence without pain. Sometimes, television violence is even supposed to be funny, but grownups know, or are supposed to know, that real violence causes lots of pain and sadness. A young gunshot victim is brought into an emergency room and he astonished his Doctors. He expressed surprise that his wound actually hurt. His Doctors first thought, Boy! This boy is really stupid. But it dawned on the Doctors that what the sees on television is that when the superhero gets shot in the arm, he uses that arm to hold onto a truck going 85 miles an hour around a corner. He overcomes the driver and shoots a couple of hundred people while he is at it. (Early Concerns 112) Another example of violence in childrens television is seen in the cartoon Teenage Mutant Ninja Turtles. This cartoon causes confusion between fantasy and reality. Several children really do think it is okay to use physical violence with other children because the Turtles do and the Turtles are the good guys (Early Concerns 115). Childrens cartoons are among the most violent shows on television, often exceeding 24 acts of violence per hour and earning high violence ratings from The National Coalition on Television Violence. Researchers say childrens aggressiveness increases measurably after viewing the cartoon violence of Bugs Bunny, Tom and Jerry and Woody Woodpecker, which are rated as very high violence with 55 or more acts of violence per episode. (Early Concerns 113). Just as children learn things from their older brothers and sisters, they also learn from their television heroes- even bad things. Some children who watch lots of violence on television learn to fight more and others learn to become victims. Many children learn that violence is fun to watch, even in real life. These kids encourage their friends to fight. When television characters use violence to solve their problems, then some children believe that it is okay then to use violence to solve problems that they might be having. As parents we want our children to solve their problems without fighting (Sege 33-35). Violence is a diverse problem and it is necessary to address it as such. There is no doubt that excessive and extended exposure to television violence may promote violence in some children. Television promotes violence because it

Oberon and Titania Character Analysis

Oberon and Titania Character Analysis The Oberon and Titania characters play an essential role in A Midsummer Nights Dream. Here, we take an in-depth look at each  character so we can better understand what makes them tick as a couple. Oberon Oberon is angry with Titania as she is spending all her time with a changeling boy and will not give him over to Oberon to be used as a henchman. He could be considered to be quite spiteful in exacting his revenge upon her: â€Å"Well, go thy way. Thou shalt not from this grove/Till I torment thee for this injury† (Act 2 Scene 1, Line 146-147). Titania accuses Oberon of being jealous: â€Å"These are the forgeries of jealousy† (Act 2 Scene 1, Line 81). Oberon is powerful but Titania appears to be just as headstrong, and they seem equally matched. We know they have had a good relationship up until now, as he and Titania would â€Å"dance our ringlets to the whistling wind† (Act 2 Scene 1 Line 86). Oberon asks Puck to get the juice from a herb he once showed him and anoint the eyes of Titania with it so that she falls in love with something ridiculous. Oberon is angry with his queen for disobeying him and exacts a kind of revenge, but it is quite harmless and humorous in its intent. He loves her and wants to have her all to himself again. Consequently, Titania falls in love with Bottom with an Ass’ head stuck on his. Oberon eventually feels guilty about this and reverses the magic which demonstrates his mercy: â€Å"Her dotage now I do begin to pity† (Act 3 Scene 3, Line 46). Oberon also shows compassion when he sees Helena being scorned by Demetrius and orders Puck to anoint his eyes with the potion so that Helena can be loved: â€Å"A sweet Athenian lady is in loveWith a disdainful youth: anoint his eyes;But do it when the next thing he espiesMay be the lady: thou shalt know the manBy the Athenian garments he hath on.Effect it with some care, that he may proveMore fond of her than she upon her love† (Act 2 Scene 1, Line261-266).​ Unfortunately, Puck gets things wrong, but Oberon’s intentions are good, and he is ultimately responsible for everyone’s happiness at the end of the play. Titania Titania is principled and strong enough to stand up to her husband (in a similar way to Hermia standing up to Egeus). She has made a promise to look after the little Indian boy and doesn’t want to break it: â€Å"Not for thy fairy kingdom. Fairies away!/We shall chide downright, if I longer stay† (Act 1 Scene 2, Line 144-145). Unfortunately, Titania is made to look foolish by her jealous husband and is made to fall in love with the ridiculous Bottom with an ass’ head: â€Å"Thou art wise as thou art beautiful† (Act 3 Scene 1, Line 140). She is very attentive to Bottom and proves herself to be a kind and forgiving lover: Be kind and courteous to this gentleman.Hop in his walks and gambol in his eyes;Feed him with apricots and dewberries,With purple grapes, green figs, and mulberries;The honeybags steal from the humble-bees,And for night tapers crop their waxen thighsAnd light them at the fiery glow-worms eyesTo have my love to bed, and to arise;And pluck the wings from painted butterfliesTo fan moonbeams from his sleeping eyes.Nod to him, elves and do him courtesies (Act 3 Scene 1, Line 156-166). As Titania is intoxicated with the love potion, she gives the changeling boy to Oberon, and he gets his way. He then takes pity on her and undoes the magic. Together Oberon and Titania are the only couple in the play who have been married for a while. The other couples are just starting with all the passion and excitement a new relationship brings. Oberon and Titania represent an older, more weathered relationship. They have possibly taken each other for granted and when the love potion is removed, and Titania realizes that she has been doting and fawning over an ass, she is made to realize that, perhaps, she has neglected her husband somewhat and this will renew their passion: â€Å"Now thou and I are new in amity† (Act 4 Scene 1, Line 86).

Human Race Past and Future in Anthropology Essay

Human Race Past and Future in Anthropology - Essay Example Agriculture means man’s interference in animal and plant reproduction as well as the distribution system-reaching peak in ecologically simplified and genetically susceptible monoculture. Dependency on few cultivated and domesticated plants decrease dependability on wild resources. The dependency makes it necessary for the society to maintain food producing economy and transformation of conventional base of society or even change of the physical environment. Change in dependency of cultivated food makes increases impossibility of returning to the gathering economy; thus, village farming communities resulted in cities and eventually countries hence attributes of civilization are firmly established and with uninterrupted material progress (Khatry 20). Therefore, agriculture was never an idea of an individual or group of individuals it developed in various ways in different parts of the world. Some of the consequences are far-reaching and similar to all people everywhere. The vari ous consequences of food production include increased carrying capacity of land, growth of sedentary society, transformation of social structure, specialization in craft and rise of civilization. Thus, whatever is visible in the modern civilization is a product of man’s shift to agriculture; moreover, not all consequences are favorable to human society. Agriculture brought a lot of pressure, chain of problems and deficiencies for man to handle particularly when the production of food moved beyond the incipient level. The significant consequences resulting from food production include increase of numbers and density of human population, the rise of political organization, conflicts and exchange, human health and biology and impact on physical environment (Haviland 300). The shift to food production though not a planned event, it has not been able to handle some of the problems it creates. While gatherers still live above starvation with less effort to procure food, agriculture struggles to feed the population despite utilization of technology. Agriculture cause damage to natural vegetation since it kills plants by use of biochemical elements. Therefore, civilization together with technology, state government increased problems in man’s life. Since narrowing of food resources to few plants and animals man’s healthy condition deteriorated (Khatry 22-23). Q2 The future of human race has been a point of concern to writers for centuries with some arguing the human race is destined to evolve into super-beings, while other writers argue that human beings are changing into goblins incapable of nothing more demanding. Nevertheless, leading geneticists believe that these observations are wrong since human evolution has halted. According to Jones, a professor at University College London believes that the forces driving evolution like natural selection and gene

History of the camera Essay Example | Topics and Well Written Essays - 750 words

History of the camera - Essay Example Nevertheless the photographic technology does not stand still, and over time people have learned how to stop the moment by invention of more convenient in use and less bulky camera. Through a variety of research projects, scientists moved to our contemporary – the portable camera, which bears little resemblance to its historical brother. The innovation has stepped so far ahead that the camera skillfully built into the phone can be found in the pocket of almost every person. In our research project, we review the features of the innovative technologies and the use of different techniques for improvement of prototype camera, having studied the history from the invention of the camera to its modern digital similar. The first notes and ideas about the reflection of objects are rooted in ancient times of China and Greece with the continuation in the 11th century experimental work of Arab scientist Ibn al-Haytamnd. These notions are about the first pinhole camera (or the camera obscura) that is able only reflect an image with its next observation or tracery by hand [Fig.1]. Then Frenchman Joseph Nicephore Niepce enters the timeline of cameras. â€Å"The first experimenter who puts a camera obscura together with permanent images made by light – who both captures and saves an image – is where the real story of camera begins† [4]. He invents the one with a lens and a sliding tube which looks like a box of illusionist and really creates miracles – Niepce has received his first photo in 1826. It is the first time a picture is made by the machine not by an artist; it is the birth of photo. Alas, the authors name is undeservedly forgotten as according to the world encyclopedi as Daguerre is considered to be a pioneer of photography. â€Å"Jacques Daguerre, another Frenchman, developed a process that used copper plates to record an image, and daguerreotypes quickly became the preferred photographic medium for portraits and other subjects† [2].

Portfolio risk management Assignment Example | Topics and Well Written Essays - 2250 words

Portfolio risk management - Assignment Example In this relation the overall comparison of the risk and return from the different investment alternatives that comprise of real estate investment and portfolio without real estate investment and correlating the same with the current weighing of investment certain result has been derived. In this relation, making the portfolio of investment through 10% investment in real estate along with 41% in SCS and 49% in LTGB is regarded to be highly efficient investment alternative or portfolio, as the relative return of such portfolio is 2.61 and risk is 4.50. Moreover, the overall analysis reveals the fact that different portfolio provides different risk and return scenario but investing the RE with relative weighting of 0.10 in RE, 0.41 in SCS and 0.49 in LTGB will provide relative lower amount of risk and higher return over the similar risk category. This is why the particular portfolio has been mentioned. Portfolio is an important concept of financial management, which refers to the combination of various investment tools including stocks, bonds, shares, mutual funds, and cash that varies based on the income, budget and period of the investor (Reilly & Brown, 2011). Additionally, the art of selection of appropriate investment approach in terms of minimal amount of risk along with maximum return is regarded as the approach of portfolio management. Moreover, the key importance of portfolio management is to derive superior investment plan for the investors. Furthermore, managing the entire budget of investor based on the different alternative will enable them to minimize the risk in comparison to investing the fund in single investment proposal and increase the likelihood of profitability. In relation to the portfolio theory, it has been assumed that investor is risk adverse and they like to select the investment proposal from the given set of investments with equal rate of return havin g minimal amount of risk. The ability to combine and form the investment based on

Impact of Slope Incline on Cart Roll

Impact of Slope Incline on Cart Roll Parth Mahajan Acceleration Cart The Aim of this practical report is to roll a car on a slope of 15 °, 30 °, 45 °. The Results then used to make a Ticker-tape graph, Displacement-time graphs, and Velocity-Time graphs with the results that have been obtained. This will show the effects on the cart and how the different aspects of the cart can be effected, (such as the Velocity of the cart, Displacement of the cart and the acceleration of the cart.) Ticker-timers will help analyze the carts motion as the dots on the ticker tape can tell various things which include: The displacement of the cart, the time taken for its total journey, the acceleration of the cart and the velocity of the cart. The Incline plane is a tilted surface which an object (in this case a cart) will slide down. The angle of the incline plane is measured from the horizontal surface to the plank used for the cart to roll down. The Greater the incline of the plank results to a greater acceleration while the smaller the incline of the plank will lead to a smaller acceleration. If friction is deduced then at least 2 forces are acted upon an object to move the object, the force of gravity and the normal force. The force of gravity The force of gravity is also known as the weight acts in a downward direction.The normal force The normal force acts in a direction perpendicular to the surface. Galileo had put this to the test and conducted appointment with the inclined planes. After he had completed the prac several times he had observed that the amount of time it took for the ball to roll down the entire length of the ramp equal to double the amount of time it took for the same ball to only roll a quarter of the distance. He had concluded with: If an object is released from rest and gains speed at a steady rate, then the total distance travelled by the object is proportional to the time squared needed for that travel. Ticker Timer, Power Pack, Wires (2), G clamp. Paper Tape, Sticky Tape Wooden Ramp Trolley Find a place to put the wooden ramp. Secure the Ticker timer with a G-clamp to the wooden ramp. Connect the ticker timer to the power pack. (Make sure you connect to the AC ports and have your volts set to 12V) Get some ticker tape, 60 cm should be enough, and attach it to your cart with some tape. Thread the tape through the ticker timer, making sure the tape goes under the carbon paper and not over. Turn the power bank on, which should turn the ticker timer on and let go of the cart. Make sure someone is there to catch the cart or it could damage the cart. Remove the tape from the cart and you should have a ticker tape with multiple blue dots. Do this for each group member Repeat the process for different angles You should do for angles 15 °, 30 ° and 45 °. 15 ° Incline The ticker tape for the cart going down a 15 ° incline has the least space between the dots out of the 3 inclines tested. This is because the acceleration on the 15 ° incline is the least. As the acceleration is the least this means that the velocity would be the smallest at a given time out of the 3 inclines. The shape of the displacement-time graph shows that the cart is accelerating, this can be seen as the graphs gradient is increasing. For the Ticker-Tape Graph, there is a constant increase in the gradient showing that the cart is accelerating at a constant acceleration. Lastly the Velocity-Time Graph the line is mostly the same gradient showing that there is a constant acceleration. 30 ° Incline The ticker tape for the cart going down 30 ° incline has averagely sized spaces between the dot out of the 3 different inclines tested. The shape of the displacement-time graph is like the 15 ° incline graph but this graph picks has a greater gradient in the end and reaches a higher velocity, this is because since the incline is greater than it means there will be more acceleration. For the Ticker-timer graph the spaces between the different parts of the tapes are similar meaning that the gradient is constant. This is the same for Velocity-Time graph, as the gradient varies a little bit but is mainly constant. 45 ° Incline The ticker tape for the cart going down a 45 ° has the most space meaning that this cart was travelling the fastest out of all the three carts. The shape of the Displacement-Time Graph for the 45 ° incline has the biggest gradient out of the three meaning that it had reached the highest velocity out of the three. The shape of the Ticker-Timer is having a steady increase in the velocity meaning it had constant acceleration. This can be seen in the Velocity-Time Graph. The Gradient of the Displacement-time graph shown the velocity of the cart, since the line is a curved line to find the gradient tangent would need to be calculated to find the instantaneous velocity. The gradient of a Velocity-Time graph shows the acceleration of the cart.       When all 9 graphs are compared, it can be seen that the greater the incline means the create the velocity reached and the greater the acceleration of the cart. The results for this prac can vary within the classroom as of human error, the angles measured werent 100% accurate meaning that there could be variations for the angles which leads to variations of the speed reached by the carts. This Prac had been completed successfully and without any major errors. It was learnt that in an Incline is plane is a tilted surface which an object will slide down, it was also learnt that the angle of the incline is measured from the horizontal surface to the planked used.   Galileo had put this to the test and conducted various experiments using the incline plane. Improvements that could be made are that the measuring of the angle could greatly be more accurate as the protractors used for the prac were just rough estimates for the angle.

Education Fiesta :: Technology Internet Technological Essays

Education Fiesta In Today’s competitive society, we all strive for the ideal occupation, and the best learning skills. Technology is a prevalent tool for us, and the Internet especially has helped bring about efficiency. Distance education is not something that I have personally experienced, but through various information sources, I now am fully aware of what online education is all about. To put my research into play I chose to narrate a scenario in which the authors of the sources I used came to my house for a dinner party. Then I provided my own ideas in an analysis of the facts that these authors presented. I tied it up with a personal reflection of everything that I learned. My dining room table pushed against the wall, buffet style, with steaming chaffing dishes, a basket of assorted fresh baked breads, a caddy filled with festive cutlery, pretty napkins laid out in a crescent shaped pattern, and various plates and bowls with the evenings fixings, anxiously I awaited my five guests of honor for tonight’s dinner: Pam Dixon, Emily Weiner, Marcia Williams, Kenneth Paprock, and Barbara Covington; all experts on the topic and field of distance education. They were to arrive at seven o’ clock, which was in ten minutes. I meticulously set up a table of beverages, and a bucket of ice. I also invited a few of my own friends and family members who were interested and about the subject, and wanted more information about online learning. My mother, who is considering finishing up her degree online, my aunt and uncle who are both in the field of computer technology and programming, my neighbor who is also doing research for school on online lea rning, and my friend Lauren who had just decided to come for the discussion, information and appetizing meal. I finished up some last minute preparation work, as the arrival time of my guests got closer. Distance learning is an alternative method of education in our society, which values time and convenience. Online learning, although not a tangible way to attend a university, allows those with families, people with busy lives, those with jobs, those with physical disabilities, and those who do not have access to universities or the right classes to learn the r skills they need, and attain the right degree, in order to work in our field of choice.

Essay on Enzymes Ph and Hydrogen Peroxide

Essay on Enzymes Ph and Hydrogen Peroxide Essay on Enzymes: Ph and Hydrogen Peroxide Investigating a factor that affects the rate if enzyme activity S(a) Possible Independent Variables * Concentration of substrate – different concentrations of the substrate can have an effect on the rate of reaction due to more particles in the solution therefore increasing chance of the particles colliding. * pH – different pH levels can have an effect on the rate of reaction due to the interference of bonds that hold the enzyme together in the active site. Therefore the specific substrate will not fit into the active site * Temperature - the temperature can have an effect on the rate of reaction. This is because when a substance is heated the particles will move faster therefore increasing the chance of collisions between the particles. * Concentration of enzyme – different concentrations of the enzyme can have an effect on the rate of reaction due to more particles in the solution therefore increasing the chance of the particles colliding. * Source of catalase – depending on the source of catalase you are using can also have an effect on the rate of reaction. There are many different sources of catalase such as potato, liver and spinach. Depending on which source you are using for your catalase can produce different results. I have chosen to investigate the effect of changing the concentration of enzyme on the rate of catalase activity. I have chosen this independent variable because it will be easy to monitor and change considering that the experiment is kept as fair as possible. It is also easy to measure with the equipment that is available to us. Hypothesis I predict using the information researched that the rate of reaction for the enzyme will be directly proportional to the enzyme concentration. I think the optimum rate of reaction will depend on the enzyme concentration. This is because enzymes can only react with a specific amount of substrate at a given amount of time. Therefore if you were to decrease the amount of enzyme concentration then the reaction would take longer. This is due to the fact that there will not enough particles to react with the substrate. For example if I put in 2g of potato then the reaction will be slower than if I put in 20g, which will then react faster. Variables Independent Concentration of enzyme Dependent Volume of oxygen (cm3) Control * Volume of hydrogen peroxide (cm3) * Volume of pH buffer solution (cm3) * Temperature of water in the tray * Time (seconds) It is important that all the control variables of the experiment are kept the same. This is to ensure that all of the results are accurate and reliable, and that any changes to the enzyme are caused by the change of the concentration of enzyme and no other factors. This will help to make the experiment a fair test. S(b) Equipment list * Potatoes – This is the source of the catalase enzyme. It is important that each sample is taken from the same potato to avoid any variation in catalase levels due to different potatoes. We will be using diced potatoes. This will make it easier to adjust when measuring for the concentration. It will also break open the cells, which releases more enzyme and will speed up the rate of reaction. * Hydrogen Peroxide – This is the solution we will be using as the substrate for the catalase. The volume of solution we use will be the same each time. * Safety Goggles and Lab Coats – this is to make sure that we protects our eyes and clothes from the hydrogen peroxide and the pH buffers. This is because hydrogen peroxide is a bleaching agent. * Buffer Solutions – These are the pH buffers that we will be using. We will be using the level 7 buffer solutions each time. * Boiling Tubes – The size and depth of the boiling tube will be kept the same so that the volume of solution will not vary each time we do the experiment. * Delivery Tube – The delivery tube will be used to transfer the oxygen in to the measuring cylinder

The Shifting Heart ¡Ã‚ ¨ This play  ¡Ã‚ §The Shifting Heart ¡Ã‚ ¨ was set in 1950s, in a community where many people did not accept any migrants. The main, theme of this play shows Bianchi family moved to Australia from Italy and how the issues raised regarding to lifestyles in Australia. The racial discrimination was one of the major issues Bianchi family faced since they moved to Australia. For example, Mr. Wilson who works at the s ¡Ã‚ §hop, thinks it is amusing to call Mrs. Bianchi, Momma Macaroni. This sees it as discrimination and it is an insult and prejudice. And in Act 1, Momma does not see the other neighbours actions as humorous and retaliates by blocking the sewer with stinking fish. And also there are people who throw rubbish. People do this rather than speak to Momma. They have never spoken for eight years since Bianchi family came to Australia. This because neighbours are obviously jealous that the Bianchi own their home through their hard work, and still other neighbours have to pay for their rant. However, this play reveals that the attitudes in today ¡Ã‚ ¦s Australia towards migrants have changed significantly. They are more migrants in Australia compared to back in 1950s.

Television Interview with Bill Mckibben - Essay Example Human being shave not left the earth alone. They are carrying out activities that may significantly change not only the earth but also its climate. In this regard, carbon dioxide has been recognized as the main culprit. In fact, the single activity that would be most likely to have a significant impact on climatic conditions is burning of gas, oil, coal and other fossil fuels. Fossil fuels are made up of carbon and therefore burning them would produce carbon dioxide. Since the early 19th century, when the burning of fossil fuels in large quantities began, the levels of carbon dioxide in the atmosphere have increased by more than thirty percent. This has led to an increase in global temperatures from 1 to 2 degrees Fahrenheit. While this may appear to be a minor and even inconsequential increase in temperatures, it has had devastating effects. Numerous books, journals, essays and magazines have been written to this effect and an equally large number of propositions made on how to salv age the situations to save planet earth or even mitigate the effects. No other book captures more graphically the grim picture pertaining to climate change as Eaarth: Making a Life on a Tough New Planet, by Bill McKibben. The following is an excerpt of a television interview in which Bill McKibben talks about the book in particular and climate change in general. With him is a panel of media pundits (Stanley who is hosting the show, Joyce and Craig) and Richard (from Africa), all bound to express their views on the issue as well. Stanley: Bill, thank you for honoring our invitation and welcome to this show. Quite a lot has been said about climate change and your book has extensively touched on the issue. Please enlighten us on the views expressed in the book. Bill: Thank you Stanley. As you have said, climatic changes have been a major concern more so in the recent times. While most of our governments are flirting with the issue, it is important to acknowledge that the implications o f climate change and global warming are quite severe. Look at the changes that have been experienced in many parts of the world. The environmental news has actually deteriorated. Have we not seen ice caps vanishing, oceans acidifying and crops failing more than we have ever seen in the past? Can our forefathers recognize this earth if they were to rise from their graves? I doubt that. We are no longer living in planet earth as they knew it but rather Eaarth. Unfortunately all this has been caused by insensitive human activity. Craig: With all due respect Bill, don’t you think we are overlooking quite a number of things in this respect. I definitely agree that there has been a significant rise in the temperatures as to cause all those things that you have talked of. However, it is important to acknowledge that we know very little about the environment, pertaining to its history, its current state or even how we can protect and conserve it. The debate that we hold actually over states the level of existing knowledge as well as its certainty. Of course I agree that carbon dioxide levels are increasing in the atmosphere and human activity is actually the main culprit. However, how can you be sure that this is the cause of increase in temperature and the consequent changes while we are in the middle of a natural trend of global warming that kicked of around mid 19th century just when we were emerging from the â€Å"Little Ice Age†
