Engineering and Constructions Executive Summary Essay

Engineering and Constructions Executive Summary - Essay Example The input is first amplified and then converted to digital signal, before the signal is listened through the speaker it is converted back to analog. Circuit explanation The power supply section converts the alternating wave to a direct wave. A transformer, Rectifier Bridge and a voltage regulator are the main components of the power supply. A mixer mixes two signal and produce a mixed wave. A graphic equalizer has basically three sections; a splitter, filters and a combiner. Splitter splits a signal and filter filters a particular frequency. Combiner combines the frequencies after filtration. Voltage and power amplifiers are utilized to enhance the power and quality of the signal. Circuit calculation Assumptions are made and values for mixer transistor, input, power supply, graphic equalizer, and voltage and power amplifiers are calculated to produce the circuit. Circuit test The calculated values are tested on the circuit and it is found that the calculated values have approximately same results on the circuit. Project cost The total cost of the components is almost $36.24. The industry partner cost is about $4800 and the total student cost is about $11200. Review of Risks The risks involved in the utilization of electricity and other electric instruments could be minimized by following the rules and regulations of electric safety.

Project should be divided into various parts and each part is scheduled accordingly. Conflicts will be minimized by considering a ll the options. A change strategy should be there and industry partners could impose any changes in the project. INTRODUCTION The word ‘Karaoke’ is taken from the Japanese language, where ‘kara’ and ‘oke’ are combined to drive the meaning of ‘karaoke’. The word ‘kara’ means ‘blank’ and ‘oke’ is derived to term orchestra. In general, a machine that eliminates the lead vocalist from a song or a music video is known as karaoke machine. The karaoke machines were developed to provide a singer with the full orchestra. At places where there is a need of orchestra and it is impossible to provide a singer with the full orchestra, karaoke machines are utilized to fulfill the lacking of band or orchestra. Audio cassette tapes and video cassette tapes were employed by the early karaoke machines. By the advancements in the technology, karaoke machines used compact disks, video compact disks and DVDs. Now a day the digital electronics revolutionized the technology and the basic structure of karaoke machine is changed as compared to its early version. The title of our project is â€Å"Transistor Level Implementation of Karaoke Machine with six-band Graphic Equalizer†. In the project our mission is to develop a karaoke machine with a six band equalizer. The karaoke machine is utilizing transistor instead of op-amps. The circuitry is not a complex one. The concept of six band graphic equalizer has enhanced the division of frequency into its various

Incident Response Essay Example for Free

Incident Response Essay Any network can be subjected to security compromise. There is no amount of coding or access control that can ultimately prevent an attack to a network. However, there is a need for any organization to ensure that their networks are safe and their incidence responses are effective. There are many tactics and tools that are employed by attackers to evade any detection by the investigation or incidence response teams, remain anonymous and to avoid attracting any attention by looking like normal users. If this fails, the attacker has the ability to degrade the system to make investigations more complicated. It is also important to note that the attackers are always technically more advanced than the security staff managing the network security monitoring systems and in some cases may be more sophisticated than the investigators (Mobrien, 2003). There are a many tools that are available to intruders that can be used to penetrate the network security monitoring systems. These tools are available in the internet including vulnerability of different software and how to develop programs that can penetrate networks. Other than being readily available, these tools are becoming increasingly easy to use making it possible for anybody with basic knowledge to be able to attack a computer network. Some of these tools include programs such as remote penetration and local penetration that can control a computer in the network without any authorization, network and vulnerability scanners, password crackers and sniffers (Mobrien, 2003). The attacker employs different tactics to promote anonymity. This is by using all means to separate all possible ties between the computer to which the attack is directed and the computer in which the attack is launched. This can be done by first compromising a system that is then used as a stepping stone, forging the IP address (spoofing) or using a service provider’s netblock. He can also remain anonymous by launching the attack from a trusted host who may be a close business associate or exploiting the vulnerability of the client rather than the server. To frustrate any investigation or incidence response to the attack, the attack may prefer to use public intermediaries such as an IRC channels. Rather than trying to remain anonymous, the attacker may evade detection by providing false leads to the incidence response or investigation team. This can be done by properly timing the attack to ensure that the duration between probes is sufficient to confuse the investigators. Other methods of evading detection include distributing the attack or blocking the web defacer. Moreover, it is important to note that by the attacker appearing normal or a legitimate user of the system is an effective way of frustrating incidence response (Bejtlich, 2004). Although protecting the network from such sophisticated malicious attack is in many instances considered a trivial task, there are some incidence responses considerations that need to be incorporated in the network security monitoring systems. Some of these security measures include an intrusion detection system that detects an intruder in the network and strict security policies in the organization. The staff dealing with the systems must also be well equipped with incident response handling abilities. The staff should be aware of when to inform the police or called emergency incidence response. The staff should also be able know when the network has been broken and the most appropriate measure to take. It is also suggested that administrators or consultants with high level of knowledge and experience in systems vulnerability and management should handle incident responses (Mobrien, 2003).

History Of Cambodia In The 20th Century History Essay

History Of Cambodia In The 20th Century History Essay Cambodia is a country that is about the size of Missouri which is 69,898 square miles or 181,036 square kilometers. Cambodia is located in Southeast Asia on the Indochinese peninsula. Thailand borders Cambodia on the northwest side, Vietnam borders Cambodia on the southeast side, and to the southwest is the gulf of Thailand. Phnom Penh is the kingdoms capital and is the largest city. Phnom Penh is the center of political, commercial, industrial and cultural activities. Cambodia in the 20th Century was under French rule. There were some economic developments that took place in Cambodia. Some of these economic developments were roads and railways were built and the rubber industry grew up. Unfortunately the Cambodians were forced to pay high taxes and from the 1930s Cambodian nationalism grew. The Japanese then occupied Cambodia in 1941. At the beginning the Japanese allowed the French officials to remain in their posts but in March 1945 as the Japanese were losing the war they were very desperate and tried to befriend the Cambodians. Finally they arrested French officials and then Cambodia was declared as independent. When the Japanese surrendered the French took over Cambodia again in October 1945. When the French gain control over Cambodia for the second time they did not allow them to have political parties and a constitution. A treaty of 1949 made Cambodia semi-independent. King Sihanouk dismissed the government in 1952. He took personal control of Cambodia and formed his own political movement. Between the years of 1955 to 1970 he took complete domination of politics that this era was often referred to as the Sihanouk era. His father died in 1960 and he named himself Chief of State. He called this movement Buddhist Socialism. The interesting fact was that this really was not a socialist at all. Sihanouks control started to dwindle in 1968 when the communists began a civil war. In Sihanouk left Cambodia in 1970. After Sihanouk left the country the National Assembly voted to remove his title as chief of state. Cambodia was then renamed Khmer Republic. The communists were in the spot light. Cambodia was bombed by Americans. America bombed this country to try and stop the communists. Then on 17 April 1975 Phnom Phen was finally captured. In the year of 1975 a horrible and devastating incident occurred. In the reign of the Khmer Rouge they were led by Pol Pot who is also known as Brother Number One. Millions of people were killed by Pol Pot and the Khmer Rouge. The exact number is not known for certain but the estimated amount is 1.5 million and it may have been as many as 3 million. Pol Pot stated that history would begin again in Cambodia. The first revolution was now the first year of history for Cambodia. Cambodia was mostly an agricultural country in 1975. Pol Pot decided he wanted it to be completely agricultural. All the people who resided in towns and cities were forced to move to the countryside. He also stated that agricultural output should be doubled within four years. This is completely an unrealistic target. He put a banned on private property and collective farms were formed. Workers on these farms were forced to work long hours to try and grow extra rice. They were mistreated because they werent given enough food to eat and many got sick from illness and died from a combination of exhaustion and malnutrition. Pol Pot also banned religion. Any people who were caught practicing Buddhism were automatically executed for it. Family relationships were also banned because he felt that parents exploited their children. If anyone broke a rule even if it was a small rule they would be executed. People were also being executed for being lazy and for complaining. Khmer Rouge also murdered intellectuals. People who spoke a foreign language or who were glasses were executed. This horrible situation was finally ended by the Vietnam War. The Vietnamese invaded Cambodia in December of 1978 and they prevailed very quickly. After Pol Pots capture he escaped and he passed away in 1998. The soldiers that worked under Pol Pot fled to Thailand and they were welcomed by the Thais who feared an invasion by the Vietnamese. The Khmer Rouge still continued to try and cause chaos. They continued a guerrilla war against the Vietnamese. Thankfully the Vietnamese forces withdrew from Cambodia in 1989. After the forces withdrew several different parties decided to try and negotiate amongst one another. The negotiations lead to a Paris Peace Accords of 1991. They abandoned Communism in Cambodia and a provisional government ruled until 1993. After the provisional government was ruled elections were held and a constitution was framed. Sihanouk was made a constitutional monarch and in 1999 Cambodia joined ASEAN. Today Cambodia is still a very poor country. There is hope for this country about its future. In the early years of the 21st Century the Cambodian economy grew very fast and with good results. The fastest growing industry for Cambodia is tourism. Cambodia also has a clothing industry and this industry is beginning to rise as well. Some events that have had an impact on Cambodias economy would have to be Pol Pot and his leadership. Pol Pot tried to make the country into a completely agricultural economy and he tried to do this unrealistically. He wanted production to happen overnight and this was nearly impossible. I also believe the war in Cambodia created a huge impact on Cambodia. Anytime you have leaders who are doing no good for a country and are doing bad it has a huge impact on a country. Many of the Cambodians died when Pol Pot was in charge of the country. Also when a country goes to war this too leads to a poor economy. This is because the country normal has to start all over again from scratch. They have to try and build up their country again or try and make their country more prosperous than it was in the beginning. In doing so this takes time and I believe this is what Cambodia is trying to do now. The current economic system is mainly agricultural but they are also trying to build up their industrial system as well. As mentioned before Cambodia has clothing industry which is helping the country builds up their economic system. The clothing industry is expected to rise within the next few years. Also tourism is the countrys most successful means of industry today. The countrys economic system is a reflection of its history in different ways. For example tourism helps Cambodias economy. This is because many tourists want to visit this country because they are intrigued with the countries. Pol Pot ruined the countrys economy by his controlling leadership style and his unrealistic idea of changing the countrys economic system. Many tourists visit and learn about the countrys history of when Pol Pot was in control and find this very intriguing and this brings many tourists to this country. Tourism is the highest means of industrial success for this country. Therefore I believe this country will be able to have a successful economic system despite their history. I am very optimistic in believing this because I believe that with all the tourism this country is gaining this will help stabilize their economy. However I believe this country might face some problems in doing so. Cambodia is still a very poor country. It is very hard to make a poor country into a successful one. I dont think that Cambodia will ever be a prosperous country but I think they could be successful and be stable. I also think another problem that could result is that another powerful leader could try and take over this country. They banned communism but who is to say that this might be allowed again. If a powerful leader tries to take control of this country this could result in bigger issues than what Cambodia is facing today. This could either mean that the country would go back to being under someone elses power and end up even worse off than what they already are . If this doesnt happen then the country might go to war again to protect their country from a future leader and their control. I dont believe this will happen but it is a concern. I think with that this country has potential it will not happen overnight but I believe that it will be a successful country in the future.

American Cultural Myths Essays -- ideal families, ideal lifestyles, id

The United States and cultural myths pertaining to this country have been a topic of discussion for many years. Stephanie Coontz’s â€Å"The Way We Wish We Were†, David Brooks’ â€Å"One Nation Slightly Divisible† and Margaret Atwood’s â€Å"A Letter to America† are all essays about different American cultural myths. Each author focuses on a different cultural myth that pertains to the United States. They explain how these myths are thwarting a realistic view of America. As well as changing the perception of the country as a whole. The major cultural myths of America among the texts are about â€Å"ideal families†, â€Å"ideal lifestyles, and a â€Å"ideal country.† Many couples in the United States idealize the myth of a â€Å"tradition family†. The idea that a woman can spend quality time with her child while maintaining an effective sexual life with her partner seemed to have caused a lot of stress during the 1950s. Coontz’s says â€Å"this hybrid idea drove thousands of women to therapists, tranquilizers, or alcohol when they tried to live up to it.† (Coontz, 569). Which explains that it is merely impossible to try to mold a family to be â€Å"ideal.† Many families still strive for a traditional life, which they define as life â€Å"back in the day.† They need to forget the past and start living in the 21st century. â€Å"Two-thirds of respondents to one national poll said they wanted more traditional standards of family life.†(Coontz, 582). Which goes to show that many families want to change to what once used to be perceived as an â€Å"ideal family† but â€Å"the same percentage of people rejected the idea that women should return to their traditional role.†(Coontz, 582). Families want to take bits and pieces from what used to be â€Å"traditional families† over time and create their own i... ...United States once had amongst the world has lessened, which is also why seeing America as an ideal country would be thwarting a realistic view of the country. If the United States just takes a step back from trying to be the most dominant country, it can regain its status among other nations. Stephanie Coontz’s, David Brook’s, and Margaret Atwood all discuss American cultural myths in their respective essays â€Å"The Way We Wish We Were,† â€Å"One Nation, Slightly Divisible,† and â€Å"A Letter to America.† All three authors elaborate on specific cultural myths, whether it is about an ideal family, an ideal lifestyle, or an ideal country as a whole. As a result of analyzing the three texts, it is clear that the authors critique Americas image in their own was. As well as elaborate on why the realistic view of the United States is being squelched by major cultural myths.

Drugs in Lebanon

Facts and Official Action Cannabis has been grown in the Beak valley ever since the Roman Empire, despite the laws prohibiting it. A long-running measure by the government before the Civil War was to burn the fields before the yearly harvest. The war stopped that action and the country became one of the most prominent in the world in the production & export of illicit drugs, reaching its peak in the late sass's at 1000 tons of cannabis resin and 3 to 5 tons of heroin, which had only been introduced a few years earlier.In the early says, after the war ended, the eradication began again, but with the absence of alternative income sources and the promise of international aid that never materialized, this action plunged the local population in dire poverty, so much so that they have nothing more to lose and so they replant their crops every year. The culture and production had been In steady decline, and by 2002, most of It was Limited to the extreme north of the valley. But due to the r ising political unrest since 2005, it has significantly increased again.With the close watch of the land and sea borders for the traffic of arms, whisking of drugs out of the country has become harder, thereby forcing the growers to broaden local markets, increasing the local consumption, which has now become a serious epidemic amongst the Lebanese youth. In 1998, Lebanon passed Law 673, which stated that drug addiction was not a crime in itself. But there was no real implementation of the policy, and the Government continued offering only two choices: prison or abstinence.With some of the dealers being politically protected, and thus unreachable. Punishment came hard on users. They were caught, trialed, and held in conventional prisons for varying periods. However, recently, the Minister of Internal Affairs and the Minister of State for Administrative Reform stated clearly that addiction should be placed midway between crime and Illness, and that the addict should be treated Instea d of imprisoned with criminals, murderers, & traffickers which will be nothing but an additional cause for drug use.They are starting to promote cooperation between Government and No's where the addicts is caught and sent to rehab for proper treatment. Many dealers were and continue to be seized, as fortunately, action now concentrates on the root of the problem rather than the consequence. However, the Government still has a long way to go, as no official studies have Eden conducted on menders, prattles, Ana correct governmental reenrolled processes, and no rehabilitation centers are government-based.Numbers and Non- Governmental Organizations There are currently 7 available rehabilitation centers in Lebanon, all No's, offering awareness, prevention, non-residential programs to short or long residential programs. Their success rates are more or less high, depending on the programs they offer and their social reintegration processes. The centers are Mum el Nor, Skunk, Jejuneness Ant i Drogue DAD), Jejuneness Centre la Drogue COD), Bonjour du Ceil, Cancel De la Lumpier, and Horizons.To report accurate numbers would be impossible, as no serious official study of the matter has ever been conducted. Some incomprehension studies conducted by unofficial bodies, namely rehabilitation enters, and mainly in the region of Beirut alone show the following statistics: There are 10,000 to 15,000 estimated drug addicts in Lebanon, of which 2000 are female. This number could rise significantly if studies on other regions are conducted. 24% of prison inmates are drug users. Around 700 addicts receive treatment per year.A soaring 49% of all addicts fall in Beirut, with the other 51% divided amongst 6 other regions. Drug-related deaths are very underreported, and that for several reasons, mainly pertaining to the taboo nature of the issue, where families prefer to disguise he reason of death, when disclosing it might help other users. Average age for first time use has dropped dr amatically from 28 years in 1996 to 17 in 2000, to 15 in 2009, with 60% between 14 and 19, to 22% between 20 and 24, to 9% between 25 and 29, to small portions after that.As for educational level, the highest rate falls within people who have reached complementary school with 31%, but this does not indicate that education prevents addiction, as lower levels like primary school and illiteracy together represent only 18% whereas higher levels like some or full university education represents 27%. Socio-economical status seems to be more defining, as medium class contains 57% of addicts, versus 38% for low class, and only 6% for high class. But it is also important to note that the classes themselves are not equally divided.What is most interesting is that 80% of all addicts are single, divorced, or separated, with only 20% married, which clearly states that people with less responsibility and sense of purpose tend to fall deeper into that abyss. As for drug- related diseases, 43% of a ddicts show psychopathology diseases, whether before he addiction and leading to it, or after it, as effects of it, 25% have other chronic diseases, 20% Cardiovascular, 17% Hepatitis C, 7% Pulmonary, 2% allergies, 2% Diabetes, and 0. 5% AIDS. Needle sharing is not uncommon, and if it happens with AIDS or HIVE patients, these diseases will soon become an epidemic in Lebanon.Cannabis has the highest abuse rate at 66% but is considered a soft drug, less harmful than Heroin, which has a high rate of 65%, versus Cocaine 56%, Alcohol 47%, Ecstasy 20%, Amphetamines 13%, LSI 8%, and inhalants 2%. It is clear that poly substance use is very common. Cocaine and LSI are rising fast. It is very important to note that all the above numbers represents addicts, not occasional users. It is not uncommon to see people at parties having smoked cannabis, snorted cocaine, or popped ecstasy. So what makes an addict? Addiction is a disease, but it in not contagious.In order to develop, it needs the right accommodation AT assistance, personality, Ana solo-cultural Doctors. I en assistance needs to have addictive properties and has to meet the specific needs of the user. For example, Cocaine will satisfy a person with underlying low self-esteem, while Heroin would be the drug of choice for an overly sensitive person. The person needs to have genetic predispositions, psychological fragility, problematic relationships, and some sort of frail social skills, and of course certain expectations of what the drug would do for them.An antisocial or aggressive personality or morbid traits would also be determining factors. The socio-cultural factors should reflect some chaos and uncertainty, like a chaotic home or ineffective parenting, low communication, war, unemployment, or poverty in a consumer society, failures, loss of values, and the availability of the drug, affiliations with drug abusing peers, or peer pressure. Put together, these three factors are a fertile ground where addiction wil l grow and thrive until the person realizes that instead of solving his problems, it is making things much worse.What starts as an attempt to self-medicate ultimately backfires. Instead of treating the problem, drugs simply mask the symptoms. The problem is still there, but now, there are more issues at hand. Relationships are worse, poverty is accentuated, performance is hindered, and added to all the previous drawbacks is he acquired dependency to a substance that is potentially fatal. By then, it is too late, but only to an extent. An addict typically tends to be in denial as a strong defense mechanism for the substance that has now become his life.It matters more than anything else, more than friends, than family, than loved ones, than life itself. More than him. He has forgotten how to function without it, and even if he does realize that he is not really functioning, and that he is in a fast cycle of self- destruction, he cannot do much about it on his own. The drugs have alte red his rain, literally altered the way it looks and functions. Overcoming the addiction is not simply a matter of willpower. It is a disease and should be treated by professionals. In Utopia For a society to be free of drug addiction, the grounds have to be made infertile.Of course, the substance has to be made unavailable, the dealers caught and punished, the laws applied, the pharmacists infused with conscience, or at least punished so hard that they fear doing wrong. But even if the substance were hard to control, the other factors could be dealt with. The government would concentrate on the people it as elected to serve in the first place. It would strive to provide political and economic stability, health care, Job opportunities, and a secure future, giving the people a sense of pride, values, patriotism, and the feeling of belonging.If it weren't perfect in the first place, and suddenly acquires a conscience, it could contain addicts and treat them by opening rehabilitation c enters or helping existing ones grow, setting solid reintegration processes, and providing free psychological support and treatment to both addicts and their families (and other citizens). After all, it did argyle have a hand in their misfortunes in the first place. Finally, parents would know better than to become parents if they are unstable. They would treat their own issues before having children and passing on to them the troubles acquired from their own parents and past experiences.They would seek treatment to rid themselves of the frustration, the intolerance, and the shattered values caused by years of strife and instability. They would understand the importance of a stable none, loving support, detective responsibility, g values, Ana realistic expectations. Sadly, Lebanon is no Utopia. The Government continues to arrogantly refuse to assume its role as rightful servant and protector, and parents continue to ignore their responsibility of providing love before money, and sec urity before comfort.So it falls on our shoulders, yours and mine, to act with continuous awareness and assume the responsibility of grace. A closer look Most common international narcotics can be found in Lebanon. Taking a closer look at their nature and their effects will help a better understanding of why they are used. A drug, or psychoactive substance is any natural or synthetic chemical that has he ability to affect thinking, feeling, senses, and/or behavior, by acting in the brain on mechanisms that normally exist to regulate the functions of mood, thoughts, and motivations.

Media Violence and Children Essay

Your children are surrounded by violence. From video games and television to the news itself, bloodshed is everywhere. Many parents and educators fear that violence seen on the media will at the very least desensitize children, and that it may even make children more likely to commit atrocities themselves. Other people claim the violence seen on the media is not real, and that children understand this. So who’s right? In order to better understand this crucial issue, we need to examine the history of violence in entertainment as well as revelations made possible by modern science. Violence in entertainment is not new. Even in ancient Rome, people gathered to watch gladiators. In gladiator combats, two trained men (usually criminals or slaves) would fight each other in front of a cheering crowd. Sometimes, men would also be forced to fight wild animals. These shows were incredibly popular; in order to accommodate the huge masses of people eager to watch the combat, Roman officials built the Colosseum, which could seat 50,000 spectators, in 80 CE. The opening of the Colosseum was celebrated with 100 days of games, during which thousands of men and animals were seriously injured or killed. Long before children watched violent cartoons, they listened to violent stories. Even our most cherished fairy tales often contain bloodshed. In fact, modern versions of fairy tales tend to be a lot less violent than the originals. For example, in Hans Christen Anderson’s The Little Mermaid, the little mermaid has her tongue cut out, almost stabs her prince, and dies; Disney’s famous version of this classic tale is significantly happier and less violent. But why is violence such a popular form of entertainment? There are several possible answers, and they are probably all true to some extent. People like watching violence because it is, at least to some degree, forbidden; all functioning societies need to have laws against murder. Seeing other people’s pain also makes your own problems seem insignificant. Finally, some violence in the media was meant to teach a practical lesson. Many gladiators were condemned criminals, so their violent and entertaining death served as a warning against would-be criminals. Public executions have served the same purpose throughout history. Fairy tales also warned children against the dangers of misbehaving. For example, the little mermaid disobeyed the rules of her father and her people, and she suffered as a result. Modern violence in the media is not that different from what occurred in the past. People enjoy watching violence because it is forbidden, distracting, and it can teach lessons about reality. At the same time, violence is becoming more and more prevalent. Additionally, much of the violence shown in video games, movies, and television is completely unrealistic; real consequences are very rarely shown, especially in cartoons. As a result, the violence may be too glamorized to teach real life lessons. Even if violence does teach a morality lesson, children may still be negatively affected. Vincent P. Mathews, a professor of radiology at Indiana University School of Medicine, discovered that watching violence on the media might actually alter brain function. Functional magnetic resonance imaging (fMRI) showed that watching violent images decreased frontal lobe brain activity in children whether or not they had previous problems of aggression. Decreased frontal lobe activity is associated with attention and self control problems. Also using fMRI, Klaus Mathiak at the University of Aachen in Germany discovered that playing violent video games and thinking about actually participating in real violent activities stimulate the same part of the brain. In other words, an individual’s brain cannot distinguish between violent actions that are committed by the individual and violent activities that are purely make believe. Additionally, violent video games may be training the brain for real life violent behavior. So what does all of this mean for parents? Children, like adults, are naturally drawn to violent images, and it is possible for children to learn valuable lessons from violent stories. However, exposure to too much violence, especially glamorized violence, probably does have a negative impact of children. Although more scientific research needs to be conducted before conclusive answers can be given, children may have a hard time distinguishing between real violence and fake violence, and simply watching violence may lead to increased behavioral problems. If you are worried that your children are watching too much violence, you should monitor exactly what they are watching. Movies and video games both have rating systems, and all televisions 13 inches or larger that were manufactured in the United States since January 2000 contain V chips. V chips allow parents to control what programs are watched, even when the children are unsupervised. You could also limit the amount of time that your children are allowed to spend watching television or playing video games, regardless of whether or not the programs or games contain violent content. Finally, you can discuss the reality of violence with you children to make sure that they can differentiate between make believe and reality.
