The question of how to educate a child is one of the most important a parent can ask. A basic choice that many parents struggle with is that of public vs. private school. Parents do not want to take on unnecessary expenses if they will not ultimately benefit their child. After all, many public schools do an excellent job of educating students. But while it is true that public schools do not have tuition costs (and a private school can run, on average from 12,000 to 30,000 dollars a year), the benefits of a private education can still far outweigh the costs depending on the local options parents may face.
Students who attend private schools can be more academically challenged, exposed to clearer value systems, given greater access to teachers, and may simply feel safer than local public school options. If you do decide to pursue private schooling for your child, start the research process early. Admission to private schools can be competitive, and finding a school that is a perfect fit for your child where he or she will be also be accepted, may take some time.
A Higher Bar:
A major advantage to private education is that your child will likely be challenged to a higher academic standard. Private schools can be more academically rigorous than public schools, and private school students may have to meet more criteria to keep up their grade point averages. According to The Condition of Education 2001, from the National Center for Education Statistics, Private high schools typically have more demanding graduation requirements than do public high schools.
Compared with public schools, private schools required more coursework (in 4-year high school programs). More can be expected of private school students in terms of quality of work, course workload, and special requirements such as community service or Arts participation. In some schools, what would normally be considered extracurricular activities, are prerequisites for graduation, which ultimately round out students’ high school experience. The push to meet this higher standard often results in a greater level of student performance. In a recent NAEP report it was found that, ‘Students in private schools scored significantly above the national average in grades four, eight, and twelve.
As the report put it, ‘Performance results in 2002 show that, at all three grades, students who attended nonpublic schools had higher average writing scores than students who attended public schools. ‘ In general, a student given the opportunity to attend a private school will most likely reach a higher level of academic achievement.
Student Teacher Ratio:
Private schools also tend to focus on controlling their class sizes. The NCES Schools and Staffing Survey found that, ‘Private high schools on average are less than half the size of public schools. In central cities, for example, the average size of a private high school is 398, compared to 1,083 for a public school. ‘ Students of private schools may have more opportunities to form relationships with their teachers, which can lead them to greater academic success. In such cases, a student is given help for his or her specific academic problems, which can allow the issue to be resolved quickly and correctly.
Once any issues inhibiting a student’s progress have been addressed, the child can go on to achieve at his or her highest level. In The Condition of Education 2002, it was found that, ‘Placing students in small groups tends to foster close working relationships between teachers and students, thus enhancing learning, particularly among at-risk students and those in the early grades. ‘
Also, small classes allow the teachers to have a better sense of who your child is, and what his or her specific strengths and weaknesses are. Your child will also have more opportunities to speak up and participate in class discussions. In addition, students may be offered office hours during which the teacher will be available. Students who have worked closely with their teachers are less likely to feel intimidated about using such time to actively seek help from their teachers directly.
Exposure to the Arts:
Private schools have the ability to create their own curriculum. Although, they must ultimately prepare students with the same basic course as any other school, private schools also have the option to add various elements to their programs. Private school administrators often develop programs that emphasize the Arts, perhaps more so than local public schooling options.
Schools may choose to produce elaborate plays and musicals, giving students unique opportunities to explore their talents and express themselves. Government regulations on public schools prevent them from spending more than a certain percentage of school funds on the Arts. Private schools, however, are not subject to the same regulations, and they have more freedom to develop and expand these programs as they wish. Some private schools may even offer filmmaking or video production courses which are opportunities normally reserved for college students.
Potentially More Funds:
The tuition that you and the other parents of a private school contribute often will go toward developing and funding special programs that would be restricted in public schools. The school may be able to offer other activities such as special field trips that reinforce the school’s curriculum. Such trips can give your child opportunities to form close friendships and build independence. The school may have more funds available to provide supplies to student-run clubs. The school also may create programs that better tie the arts or sciences into the overall general curriculum.
A Push Towards College:
Private high schools can instill their students with the expectation of attending college. Data from the National Education Longitudinal Study of 1988, ‘Fourth Follow-up’ (NELS: 1988/2000) show that, ‘Students who had attended private school in 8th grade were twice as likely as those who had attended public school to have completed a bachelor’s or higher degree by their mid-20s (52 versus 26 percent) and far less likely to have had no postsecondary education. ‘
With college as a focus, students can be more goal oriented, and often elements of the schools curriculum will be specifically aimed at preparing your child for college. Many private schools are even referred to as ‘college preparatory. ‘ Private schools often encourage their students to take an active role in their own college admission process. Students may be given more access to information about college options, and they may be made more aware of the requirements they must fulfill to qualify for a specific school.
Community Service and a Sense of Values:
Private schools often put a major emphasis on personal values. When choosing a private school for your child, it is possible to find a school that incorporates a great deal of your own values into its everyday curriculum. Private schools often have honor codes and stricter behavioral standards that help students develop into mature adults.
According to The Condition of Education 2001 from the National Center for Education Statistics, ‘At private schools, a greater percentage of children had parents who were very satisfied with order and discipline than with the school or teachers in 1999. ‘ Parents are often given greater say in school policies at private schools.
Many private schools require that their students complete a mandatory number of community service hours. This not only provides the obvious benefit of instilling a sense of respect for the community and the importance of making a contribution to society, but it also happens to be something colleges especially favor. Students may also find possible career options while fulfilling this service requirement such as political involvement to aid the community or counseling for endangered teens. Community service experiences teach students that education goes beyond the walls of the school, and that it sometimes requires action and initiative.
Discipline and Safety:
Beyond the fact that smaller classrooms are by their very nature easier to control, most private schools put special emphasis on discipline. Even if your child does not have discipline problems, disruptive peers could take away from your child’s valuable learning time. The Condition of Education 2002 states that, ‘Private school teachers were more likely than public school teachers to say that they had a lot of influence on setting student performance standards (63 versus 38 percent) and on student discipline policy (48 versus 30 percent). ‘
The push for discipline in private schools teaches children self control, which will ultimately be a requirement in college where the student will be far more responsible for his or her own attendance, and achievement. Also, stricter disciplinary policies mean that any major problems will be handled and eradicated quickly. Typical crimes that plague public schools are less common at private schools. The School Crime and Safety Report found that, ‘Students in public schools (37. 3 percent) were more apt to see hate-related graffiti at school than their counterparts in private schools (16. 8 percent). ‘
A Word About Teachers:
Because teachers at private schools are not required to earn the same certifications as public school teachers, some parents worry that the teachers are not as qualified. This is not necessarily true. Private schools must maintain their reputations and create positive word of mouth to survive. Toward this end, private schools are generally very selective about who they place in front of their students, and they choose educators with training specific to the subject they will be teaching.
A Community in Itself:
When you decide to enroll your child in a private school, your family becomes part of a network of families with the same goals. Parents at private schools are more involved in the lives of the students and various school events. As a parent, you may have the opportunity to connect with other parents to discuss the lives of your children. Such relationships allow parents to learn from each other and support each other.
The students also benefit from the community atmosphere of private schools. The very specific personalities of private schools often lead the students to have a strong sense of pride and loyalty to the school and its community. The student may also benefit from affiliation to the school far beyond graduation day. Many private schools have alumni mentoring programs that connect older alumni with newer ones. Recent graduates may find internship opportunities with alumni who have been working in their field of interest.
Every Family is Different:
Despite the numerous benefits of private schooling, it must be said that private school is not for every child. Some children would benefit from the diversity a public school can offer. Some parents would prefer their children to be more focused on the core subjects rather than the arts and extracurricular interests. And, of course, the financial burden that a private school brings is considerable. No student is exactly the same as another, and only a parent can know what the best option is for his or her child. Any child, whether in private or public school, will need the active participation of his or her parents in order to achieve true success.
School Choice:
The major advantage of private schooling is choice. Rather than sending your child to a public school that is required based on geography, now you have opened up a selection of several schools that may have very different educational styles and emphases, simply because you are deciding on private education. Every private school has a unique personality, and with a little research, certain schools will emerge from the pool as having more features than that will benefit your child.
Perhaps the school is affiliated with your family’s religious faith, and your child can be given a religious education along with his or her core studies. Perhaps the school emphasizes writing, or it pushes self-expression. With the vast variety of private schools available, it is easy to select a school that will help your child to shine and develop the values you find most important.
Conclusion:
No choice can guarantee that your child’s formative years will go smoothly. Parents should always remain highly active participants in the education of their children. Still, in the interest of giving a student the most advantages and opportunities possible private school can be an attractive option.
Private schools can reduce worries about safety, increase a child’s exposure to discipline, offer reduced class sizes, and offer a good environment for high academic achievement. In many cases, a private school can prove to be much more than that, providing a community environment for your family and special opportunities that your child would not have otherwise.

<!– @page { size: 8. 5in 11in; margin: 0. 79in } P { margin-bottom: 0. 08in } –>There are times when technology ventures into the realm of the weird. Yet, the spin-offs ultimately benefit mankind in unimaginable ways. Today?s consumer electronic news yields two such instances- both exotic and incredible. One is a humanoid from Computer Graphics International and the other is the robotic snake, the brainchild of Dr Gavin Miller. The idea of a humanoid probably germinated around 250 BC. Today?s humanoid robot does not need any maintenance, learns on its own and can coexist in a safe human environment. But, that?s not all. The technology to develop these humanoids with fuzzy logic has benefited the huge industry of gaming computers. There is more. The spin-offs are most impressive. Today?s Harry Potter films among others are a result of this technology. Enter Emily O?Brien the actress. The Emily Project resulted in a human like animation which could copy Emily?s live video images using diverse parameters like hand-eye-body coordination, lip synchronization and the like. The technology will also benefit the Security Industry in recognizing faces. Consumer electronic news talks about the robotic snake. This is an incredible marvel to help locate survivors post earthquake, house collapse or any such mishaps. The technology actually replicates not only the slithering motion of the snake but also its sharp sensory perception for changes in external conditions. The mechanical snake has its own computers and power source. Normally, it is powered and guided through an umbilical cord which can be disengaged and the mode changed to radio control when required. The need for artificial intelligence having been obviated, the snake has a sensitive camera and sound transducers. It also has a ranging facility involving IR for sensing body heat. The scales on its body permit an all terrain travel. The prime ability is perhaps the empowerment of explosive technology in order that the robot can make a 10 cm hole after retreating and enter the hole after clearing up the debris!! Today each technological find will be assessed on its utility scale. The robotic snake and the humanoid have justified their technologies on account of the widening of horizon which has resulted.

Music lovers may argue long and hard over which form of music is the better and lovers of jazz, opera, classical, rock, pop and country etc will all have differing opinions depending on where their allegiance lies. However, one area where all who appreciate music will agree is that whatever the type of music listened it is always better heard live. And who could argue that point? A concert or performance creates an atmosphere and excitement that cannot be reproduced remotely. However, Linn have spent the last three decades perfecting their Hi-fi systems in an attempt to bring the ?live? experience, just, that little bit closer. Music should never be, merely, a feast for the auditory system (ears), but, should engage our minds, through our interpretation of how it makes us feel (happy, sad etc) and, perhaps, what the composer wishes to invoke us to hear, and should affect our hearts, through fond memories and experiences we associate with our choice of musical intercourse. With the combination of precision engineering, quality sound reproduction and Ivor Tiefenbrun?s (Linn?s founder) own quest for musical sound perfection, Linn Hi Fi systems have built a world-renowned reputation for superior performance music systems. The Klimax Hi Fi music system is the flagship model in Linn?s impressive line-up and provides authentic musical accuracy through its DS digital music player, its Kontrol pre-amplifier and its 350A loudspeaker system. This Gold standard Linn Hi-Fi is for the connoisseur who values quality above everything. Akurate is Linn?s silver standard music Hi-Fi, which gives you surround sound or stereo excellence over a range of musical format formats. The Majik Hi Fi system sets the bronze standard with its straightforward approach to music deliverance of ?near? live performance quality. Adding the Linn turntable to Linn?s Hi-Fi systems allows your vinyl collection to be dusted off and enjoyed at a level of sound perfection never imagined. Rococo System and Design can assist you to make the most of your Linn Hi Fi experience, by helping you choose the correct stand alone Hi Fi product or by integrating into your Linn Knekt multi-room system. Whilst listening to your favourite music, if you can close your eyes and feel the emotional intensity of a live performance, then you are listening through or Linn music product or you are actually there in the front row.

Films are an audio visual version, yet most film makers focus solely on the visual part. They tend to forget that without a good audio quality the film would totally loose its impact!
None of your scenes would create that horror or terror or tickle without the right background score! Some of you might think that it can happen just like that – like a magic ? but, the news is that nothing in film making happens like a magic!
For a good audio impact what you need is a trained audiophile – a professional who loves to handle the boom of several wanted and unwanted noises with a microphone all through the day.
You must know that almost all the cameras have an in-built mic that records all the dialogues delivered and the other sounds during the shoot but this mic is one of a very poor quality. So, ultimately every film maker lands up working with some external mics.
Here are a few tips to understand your external mics better and enhance the audio quality of your film:
1. Look for a professional in the field who would guide you through all the technical requisites.
2. In case you are planning a lower budget, try working with a friend who is a fresher in the field. He might be inexperienced. But a well trained young talent works wonders at times, better than the far experienced ones.
3. Invest in atleast 2 good quality remote mics that must sync in with your camera. You make your actors wear these remote mics on their body. In order to make them work well, you must place them correctly.
4. Placing the remote mic is rather tricky, but once you know the right way, it is just another daily job for you. You must use your fist with the thumb extended up & pinkie extended down just like the ol’ hang’s loose hand sign. Now, place your thumb under the actor’s chin. Now where your extended pinkie ends, is where you place the mic. It means that the mic close enough in order to capture good sound, but far from enough from the actor’s mouth thereby preventing popping and sibilance.
5. For the group scenes, a mic with a boom is just excellent. The audiophiles have a real tough job that is to handle a boom for days together. But these professionals are trained for the same and are really passionate about it.
6. After the shoot and the recording of the sound done there simultaneously, these sounds are carried back to the studio. Here the film maker edits these sounds so as to match with the images. Unlike the olden days of film making, now the filmmakers have ‘the Non-Linear Systems to Edit the Non-Linear Sounds. ‘ Popularly this technology is known as the NLE ? it enables you to move your sound clips back & forth within the video itself.
7. The sound tracks and sound effects add mood and life to the film. It is always advisable to create fresh music for the film rather than copying it from some where else. Using recorded music could lead to major legal hassles that would affix your film in the post production stage only.
8. Copyrighting laws are quite strict and violating them could cost you far too much to imagine. Remember, anything that belongs to another artist/s or their agent/s, that is if they have an ownership right to the music, no one can use the same without their written permission. There are some ways around this law but not as many and not that easy as well.
9. You can only use the music that is from the public domain. You can only use the music piece or image with no ownership attached to the same, that is there are no person/s or organization/s to claim the proprietary interest of that music or image.
10. To get original work it is always good to hire a professional. To go economical and work rather comfortable try working with a fresher or a friend who is talented enough to compose interesting soundtracks and effects. These days you shall find many budding composers & musicians in search of a chance to work for a film to expose their talent and art.

The UPS is meant to only give you sufficient power to either help you switch on the alternate power like a generator / alternator or save your work and shut down the system that you are working on. When one is quite engrossed in his / her work one may not notice that the main power has failed and will continue to work with the UPS power if there are no indications.

This is where the necessity of a warning comes up. Standard UPS incorporates both audio and visual warnings for the user to understand that the power is being consumed form the battery and not from the main line.

Visual warning:

There are UPS that have one LED, two LED?s and three LED?s. For UPS with a single LED, the LED glows a green color, indicating the system is working on the main power line. When the power fails, the LED turns either amber or a red with blinking at an interval of thirty seconds indicating that the UPS is working with back up power; power being supplied from the battery that is in the UPS. After for a particular duration of time and if by then the power is not restored by switching on a generator / alternator, the light turns a bright red along with continuous blinking indicating that you have a critical two minutes left for the power of the battery to drain out and crash abruptly.

For UPS with two LED?s the green is a solo type indicating mains; and the type, then only one green light is visible. If the UPS is having two lights then the green LED is ?ON? and the other LED is off indicating main power line consumption. When the power main power fails, the other LED i. e. either a red or amber comes on indicating the power is of last two minutes. This is accompanied by continuous blinking of the LED indicator.

For UPS that have three LED?s , the green indicates UPS working from main lines, the amber indicates the UPS working from battery back up and the red LED indicates UPS working from critical backup. As mentioned in the UPS with two LED?s the blinking of the UPS is the same here too. For back up it is blinking at the rate of thirty seconds per blink and for critical power it is blinking at the rate of almost one second per blink.

Audio warning:

Almost all UPS have an audio warning incorporated into the circuit. The audio warning is a beep, which during critical back up power being consumed the beep is continuous with a frequency that is equal to the blink rate. The audio warning gives one an indication that it is high time you shout down your UPS after saving critical data.

Audio and Visual evidence is becoming more and more prevalent in court cases around the world.   In the UK there are more CCTV cameras than in any other country, some would say this is big brother watching over everything we do, others would see past the scaremongers and see that everyone is using it as it can be an effective way of getting convictions in court. The main issue with visual evidence in particular is the quality of the recording.   There are high definition quality cameras, but these are still relatively scarce due to their cost.   Visual forensic analysis can extract data from seemingly unusable digital video content and lead the way to vital information that can solve criminal cases and stand up in court. Audio forensic analysis is similar in that by examining audio that may at first listen seem inaudible; experts can extract sounds and clear any background noise to give a clear stream of audio evidence.   Such recordings can come from any number of sources including mobile telephones or recorded conversations. As an extended arm of digital forensics, audio and visual forensic experts will also look to recover audio and video information that was thought to have been deleted.   With many people storing digital data on computer hard drives or other removable media, it is often the job of computer forensic experts to first recover the data from deep inside the computer?s memory.   This multi-step recovery process, from first getting hold of the hardware that is storing the data, to recovering the data to then clean it up so that it can be clear what its contents are can be a large undertaking, but is often ultimately worth it.
