Early Childhood School Essay

‘Education To Be More’ was published last August. It was the report of the New Zealand Government’s Early Childhood Care and Education Working Group. The report argued for enhanced equity of access and better funding for childcare and early childhood education institutions. Unquestionably, that’s a real need; but since parents don’t normally send children to pre-schools until the age of three, are we missing out on the most important years of all? B A 13-year study of early childhood development at Harvard University has shown that, by the age of three, most children have the potential to understand about 1000 words – most of the language they will use in ordinary conversation for the rest of their lives. Furthermore, research has shown that while every child is born with a natural curiosity, it can be suppressed dramatically during the second and third years of life. Researchers claim that the human personality is formed during the first two years of life, and during the first three years children learn the basic skills they will use in all their later learning both at home and at school. Once over the age of three, children continue to expand on existing knowledge of the world. C It is generally acknowledged that young people from poorer socio-economic backgrounds tend to do less well in our education system. That’s observed not just in New Zealand, but also in Australia, Britain and America. In an attempt to overcome that educational under-achievement, a nationwide programme called ‘Headstart’ was launched in the United States in 1965. A lot of money was poured into it. It took children into pre-school institutions at the age of three and was supposed to help the children of poorer families succeed in school. Despite substantial funding, results have been disappointing. It is thought that there are two explanations for this. First, the programme began too late. Many children who entered it at the age of three were already behind their peers in language and measurable intelligence. Second, the parents were not involved. At the end of each day, ‘Headstart’ children returned to the same disadvantaged home environment. D As a result of the growing research evidence of the importance of the first three years of a child’s life and the disappointing results from ‘Headstart’, a pilot programme was launched in Missouri in the US that focused on parents as the child’s first teachers. The ‘Missouri’ programme was predicated on research showing that working with the family, rather than bypassing the parents, is the most effective way of helping children get off to the best possible start in life. The four-year pilot study included 380 families who were about to have their first child and who represented a cross-section of socio-economic status, age and family configurations. They included single-parent and two-parent families, families in which both parents worked, and families with either the mother or father at home. The programme involved trained parent ¬educators visiting the parents’ home and working with the parent, or parents, and the child. Information on child development, and guidance on things to look for and expect as the child grows were provided, plus guidance in fostering the child’s intellectual, language, social and motor-skill development. Periodic check-ups of the child’s educational and sensory development (hearing and vision) were made to detect possible handicaps that interfere with growth and development. Medical problems were referred to professionals. Parent-educators made personal visits to homes and monthly group meetings were held with other new parents to share experience and discuss topics of interest. Parent resource centres, Located in school buildings, offered learning materials for families and facilitators for child care. E At the age of three, the children who had been involved in the ‘Missouri’ programme were evaluated alongside a cross-section of children selected from the same range of socio-economic backgrounds and Family situations, and also a random sample of children that age. The results were phenomenal. By the age of three, the children in the programme were significantly more advanced in language development than their peers, had made greater strides in problem solving and other intellectual skills, and were Further along in  social development. In fact, the average child on the programme was performing at the level of the top 15 to 20 per cent of their peers in such things as auditory comprehension, verbal ability and language ability. Most important of all, the traditional measures of ‘risk’, such as parents’ age and education, or whether they were a single parent, bore little or no relationship to the measures of achievement and language development. Children in the programme performed equally well regardless of scio-economic disadvantages. Child abuse was virtually eliminated. The one factor that was found to affect the child’s development was family stress leading to a poor quality of parent-child interaction. That interaction was not necessarily bad in poorer families. F These research findings are exciting. There is growing evidence in New Zealand that children from poorer socio-economic backgrounds are arriving at school less well developed and that our school system tends to perpetuate that disadvantage. The initiative outlined above could break that cycle of disadvantage. The concept of working with parents in their homes, or at their place of work, contrasts quite markedly with the report of the Early Childhood Care and Education Working Group. Their focus is on getting children and mothers access to childcare and institutionalised early childhood education. Education from the age of three to five is undoubtedly vital, but without a similar Focus on parent education and on the vital importance of the first three years, some evidence indicates that it will not be enough to overcome educational inequity.

Digital Fortress Chapter 5

â€Å"Where is everyone?† Susan wondered as she crossed the deserted Crypto floor. Some emergency. Although most NSA departments were fully staffed seven days a week, Crypto was generally quiet on Saturdays. Cryptographic mathematicians were by nature high-strung workaholics, and there existed an unwritten rule that they take Saturdays off except in emergencies. Code-breakers were too valuable a commodity at the NSA to risk losing them to burnout. As Susan traversed the floor, TRANSLTR loomed to her right. The sound of the generators eight stories below sounded oddly ominous today. Susan never liked being in Crypto during off hours. It was like being trapped alone in a cage with some grand, futuristic beast. She quickly made her way toward the commander's office. Strathmore's glass-walled workstation, nicknamed â€Å"the fishbowl† for its appearance when the drapes were open, stood high atop a set of catwalk stairs on the back wall of Crypto. As Susan climbed the grated steps, she gazed upward at Strathmore's thick, oak door. It bore the NSA seal-a bald eagle fiercely clutching an ancient skeleton key. Behind that door sat one of the greatest men she'd ever met. Commander Strathmore, the fifty-six-year-old deputy director of operations, was like a father to Susan. He was the one who'd hired her, and he was the one who'd made the NSA her home. When Susan joined the NSA over a decade ago, Strathmore was heading the Crypto Development Division-a training ground for new cryptographers-new male cryptographers. Although Strathmore never tolerated the hazing of anyone, he was especially protective of his sole female staff member. When accused of favoritism, he simply replied with the truth: Susan Fletcher was one of the brightest young recruits he'd ever seen, and he had no intention of losing her to sexual harassment. One of the cryptographers foolishly decided to test Strathmore's resolve. One morning during her first year, Susan dropped by the new cryptographers' lounge to get some paperwork. As she left, she noticed a picture of herself on the bulletin board. She almost fainted in embarrassment. There she was, reclining on a bed and wearing only panties. As it turned out, one of the cryptographers had digitally scanned a photo from a pornographic magazine and edited Susan's head onto someone else's body. The effect had been quite convincing. Unfortunately for the cryptographer responsible, Commander Strathmore did not find the stunt even remotely amusing. Two hours later, a landmark memo went out: EMPLOYEE CARL AUSTIN TERMINATED FOR INAPPROPRIATE CONDUCT. From that day on, nobody messed with her; Susan Fletcher was Commander Strathmore's golden girl. But Strathmore's young cryptographers were not the only ones who learned to respect him; early in his career Strathmore made his presence known to his superiors by proposing a number of unorthodox and highly successful intelligence operations. As he moved up the ranks, Trevor Strathmore became known for his cogent, reductive analyses of highly complex situations. He seemed to have an uncanny ability to see past the moral perplexities surrounding the NSA's difficult decisions and to act without remorse in the interest of the common good. There was no doubt in anyone's mind that Strathmore loved his country. He was known to his colleagues as a patriot and a visionary†¦ a decent man in a world of lies. In the years since Susan's arrival at the NSA, Strathmore had skyrocketed from head of Crypto Development to second-in-command of the entire NSA. Now only one man outranked Commander Strathmore there-Director Leland Fontaine, the mythical overlord of the Puzzle Palace-never seen, occasionally heard, and eternally feared. He and Strathmore seldom saw eye to eye, and when they met, it was like the clash of the titans. Fontaine was a giant among giants, but Strathmore didn't seem to care. He argued his ideas to the director with all the restraint of an impassioned boxer. Not even the President of the United States dared challenge Fontaine the way Strathmore did. One needed political immunity to do that-or, in Strathmore's case, political indifference. Susan arrived at the top of the stairs. Before she could knock, Strathmore's electronic door lock buzzed. The door swung open, and the commander waved her in. â€Å"Thanks for coming, Susan. I owe you one.† â€Å"Not at all.† She smiled as she sat opposite his desk. Strathmore was a rangy, thick-fleshed man whose muted features somehow disguised his hard-nosed efficiency and demand for perfection. His gray eyes usually suggested a confidence and discretion born from experience, but today they looked wild and unsettled. â€Å"You look beat,† Susan said. â€Å"I've been better.† Strathmore sighed. I'll say, she thought. Strathmore looked as bad as Susan had ever seen him. His thinning gray hair was disheveled, and even in the room's crisp air-conditioning, his forehead was beaded with sweat. He looked like he'd slept in his suit. He was sitting behind a modern desk with two recessed keypads and a computer monitor at one end. It was strewn with computer printouts and looked like some sort of alien cockpit propped there in the center of his curtained chamber. â€Å"Tough week?† she inquired. Strathmore shrugged. â€Å"The usual. The EFF's all over me about civilian privacy rights again.† Susan chuckled. The EFF, or Electronics Frontier Foundation, was a worldwide coalition of computer users who had founded a powerful civil liberties coalition aimed at supporting free speech on-line and educating others to the realities and dangers of living in an electronic world. They were constantly lobbying against what they called â€Å"the Orwellian eavesdropping capabilities of government agencies†-particularly the NSA. The EFF was a perpetual thorn in Strathmore's side. â€Å"Sounds like business as usual,† she said. â€Å"So what's this big emergency you got me out of the tub for?† Strathmore sat a moment, absently fingering the computer trackball embedded in his desktop. After a long silence, he caught Susan's gaze and held it. â€Å"What's the longest you've ever seen TRANSLTR take to break a code?† The question caught Susan entirely off guard. It seemed meaningless. This is what he called me in for? â€Å"Well†¦Ã¢â‚¬  She hesitated. â€Å"We hit a COMINT intercept a few months ago that took about an hour, but it had a ridiculously long key-ten thousand bits or something like that.† Strathmore grunted. â€Å"An hour, huh? What about some of the boundary probes we've run?† Susan shrugged. â€Å"Well, if you include diagnostics, it's obviously longer.† â€Å"How much longer?† Susan couldn't imagine what Strathmore was getting at. â€Å"Well, sir, I tried an algorithm last March with a segmented million-bit key. Illegal looping functions, cellular automata, the works. TRANSLTR still broke it.† â€Å"How long?† â€Å"Three hours.† Strathmore arched his eyebrows. â€Å"Three hours? That long?† Susan frowned, mildly offended. Her job for the last three years had been to fine-tune the most secret computer in the world; most of the programming that made TRANSLTR so fast was hers. A million-bit key was hardly a realistic scenario. â€Å"Okay,† Strathmore said. â€Å"So even in extreme conditions, the longest a code has ever survived inside TRANSLTR is about three hours?† Susan nodded. â€Å"Yeah. More or less.† Strathmore paused as if afraid to say something he might regret. Finally he looked up. â€Å"TRANSLTR's hit something†¦Ã¢â‚¬  He stopped. Susan waited. â€Å"More than three hours?† Strathmore nodded. She looked unconcerned. â€Å"A new diagnostic? Something from the Sys-Sec Department?† Strathmore shook his head. â€Å"It's an outside file.† Susan waited for the punch line, but it never came. â€Å"An outside file? You're joking, right?† â€Å"I wish. I queued it last night around eleven thirty. It hasn't broken yet.† Susan's jaw dropped. She looked at her watch and then back at Strathmore. â€Å"It's still going? Over fifteen hours?† Strathmore leaned forward and rotated his monitor toward Susan. The screen was black except for a small, yellow text box blinking in the middle. TIME ELAPSED: 15:09:33 AWAITING KEY: ________ Susan stared in amazement. It appeared TRANSLTR had been working on one code for over fifteen hours. She knew the computer's processors auditioned thirty million keys per second-one hundred billion per hour. If TRANSLTR was still counting, that meant the key had to be enormous-over ten billion digits long. It was absolute insanity. â€Å"It's impossible!† she declared. â€Å"Have you checked for error flags? Maybe TRANSLTR hit a glitch and-â€Å" â€Å"The run's clean.† â€Å"But the pass-key must be huge!† Strathmore shook his head. â€Å"Standard commercial algorithm. I'm guessing a sixty-four-bit key.† Mystified, Susan looked out the window at TRANSLTR below. She knew from experience that it could locate a sixty-four-bit key in under ten minutes. â€Å"There's got to be some explanation.† Strathmore nodded. â€Å"There is. You're not going to like it.† Susan looked uneasy. â€Å"Is TRANSLTR malfunctioning?† â€Å"TRANSLTR's fine.† â€Å"Have we got a virus?† Strathmore shook his head. â€Å"No virus. Just hear me out.† Susan was flabbergasted. TRANSLTR had never hit a code it couldn't break in under an hour. Usually the cleartext was delivered to Strathmore's printout module within minutes. She glanced at the high-speed printer behind his desk. It was empty. â€Å"Susan,† Strathmore said quietly. â€Å"This is going to be hard to accept at first, but just listen a minute.† He chewed his lip. â€Å"This code that TRANSLTR's working on-it's unique. It's like nothing we've ever seen before.† Strathmore paused, as if the words were hard for him to say. â€Å"This code is unbreakable.† Susan stared at him and almost laughed. Unbreakable? What was THAT supposed to mean? There was no such thing as an unbreakable code-some took longer than others, but every code was breakable. It was mathematically guaranteed that sooner or later TRANSLTR would guess the right key. â€Å"I beg your pardon?† â€Å"The code's unbreakable,† he repeated flatly. Unbreakable? Susan couldn't believe the word had been uttered by a man with twenty-seven years of code analysis experience. â€Å"Unbreakable, sir?† she said uneasily. â€Å"What about the Bergofsky Principle?† Susan had learned about the Bergofsky Principle early in her career. It was a cornerstone of brute-force technology. It was also Strathmore's inspiration for building TRANSLTR. The principle clearly stated that if a computer tried enough keys, it was mathematically guaranteed to find the right one. A code's security was not that its pass-key was unfindable but rather that most people didn't have the time or equipment to try. Strathmore shook his head. â€Å"This code's different.† â€Å"Different?† Susan eyed him askance. An unbreakable code is a mathematical impossibility! He knows that! Strathmore ran a hand across his sweaty scalp. â€Å"This code is the product of a brand-new encryption algorithm-one we've never seen before.† Now Susan was even more doubtful. Encryption algorithms were just mathematical formulas, recipes for scrambling text into code. Mathematicians and programmers created new algorithms every day. There were hundreds of them on the market-PGP, Diffie-Hellman, ZIP, IDEA, El Gamal. TRANSLTR broke all of their codes every day, no problem. To TRANSLTR all codes looked identical, regardless of which algorithm wrote them. â€Å"I don't understand,† she argued. â€Å"We're not talking about reverse-engineering some complex function, we're talking brute force. PGP, Lucifer, DSA-it doesn't matter. The algorithm generates a key it thinks is secure, and TRANSLTR keeps guessing until it finds it.† Strathmore's reply had the controlled patience of a good teacher. â€Å"Yes, Susan, TRANSLTR will always find the key-even if it's huge.† He paused a long moment. â€Å"Unless†¦Ã¢â‚¬  Susan wanted to speak, but it was clear Strathmore was about to drop his bomb. Unless what? â€Å"Unless the computer doesn't know when it's broken the code.† Susan almost fell out of her chair. â€Å"What!† â€Å"Unless the computer guesses the correct key but just keeps guessing because it doesn't realize it found the right key.† Strathmore looked bleak. â€Å"I think this algorithm has got a rotating cleartext.† Susan gaped. The notion of a rotating cleartext function was first put forth in an obscure, 1987 paper by a Hungarian mathematician, Josef Harne. Because brute-force computers broke codes by examining cleartext for identifiable word patterns, Harne proposed an encryption algorithm that, in addition to encrypting, shifted decrypted cleartext over a time variant. In theory, the perpetual mutation would ensure that the attacking computer would never locate recognizable word patterns and thus never know when it had found the proper key. The concept was somewhat like the idea of colonizing Mars-fathomable on an intellectual level, but, at present, well beyond human ability. â€Å"Where did you get this thing?† she demanded. The commander's response was slow. â€Å"A public sector programmer wrote it.† â€Å"What?† Susan collapsed back in her chair. â€Å"We've got the best programmers in the world downstairs! All of us working together have never even come close to writing a rotating cleartext function. Are you trying to tell me some punk with a PC figured out how to do it?† Strathmore lowered his voice in an apparent effort to calm her. â€Å"I wouldn't call this guy a punk.† Susan wasn't listening. She was convinced there had to be some other explanation: A glitch. A virus. Anything was more likely than an unbreakable code. Strathmore eyed her sternly. â€Å"One of the most brilliant cryptographic minds of all time wrote this algorithm.† Susan was more doubtful than ever; the most brilliant cryptographic minds of all time were in her department, and she certainly would have heard about an algorithm like this. â€Å"Who?† she demanded. â€Å"I'm sure you can guess.† Strathmore said. â€Å"He's not too fond of the NSA.† â€Å"Well, that narrows it down!† she snapped sarcastically. â€Å"He worked on the TRANSLTR project. He broke the rules. Almost caused an intelligence nightmare. I deported him.† Susan's face was blank only an instant before going white. â€Å"Oh my God†¦Ã¢â‚¬  Strathmore nodded. â€Å"He's been bragging all year about his work on a brute-force-resistant algorithm.† â€Å"B-but†¦Ã¢â‚¬  Susan stammered. â€Å"I thought he was bluffing. He actually did it?† â€Å"He did. The ultimate unbreakable code-writer.† Susan was silent a long moment. â€Å"But†¦ that means†¦Ã¢â‚¬  Strathmore looked her dead in the eye. â€Å"Yes. Ensei Tankado just made TRANSLTR obsolete.†

Perspective of song lyrics and poems Essay Example | Topics and Well Written Essays - 750 words

Perspective of song lyrics and poems - Essay Example Both forms of writing do share similarities, but by no means are they exactly the same. Despite the differences between the two formats of writing, they can be transferred to each other with a little work. Poems can somewhat more easily be turned into songs with a little work and tweaking. Just the same as if a person was trying to convert numbers, or convert any format or style of writing to another, it does take a little finesse, but none the less, it can be done. Vaughn Daniel, a published writer from MusicCity answered when asked about the topic: â€Å"If I gave someone a poem and asked them to put it to music, I would expect the poem to either be added to or some of it ending up on the cutting room floor. Song lyrics are dictated by the direction the music has taken with the melody. There are also formulas of structure in writing a song. Examples are as follows: These calculated lyric structures may also dictate what the song will sound like musically. If the lyrics are structured correctly, music can be invented just by the way the lyrics flow. Take any popular song and try singing it another way. Chances are you wont like what you hear. Lyrics often take on a life of their own musically† (http://www.musesmuse.com/poem-vs-lyric.html. Daniel shows that with a little work and finesse, a poem can be turned into a song, just that you may loose some of the original impact of the poem in the final version. There are also many similarities between poems and song lyrics. Both poems and lyrics require a person to have a strong command of what ever language they are writing in. These art forms also require the person to be expressive, and to be able to shed their feelings through their medium and express themselves. This is not an easy task, but one that comes though much work for many writers. Also, â€Å"Both poems and song lyrics rely on the potent use of language, Both engage their readers and

Pros and Cons of a Person With a Mental Illness as a US President Essay

Pros and Cons of a Person With a Mental Illness as a US President - Essay Example Some mental disorders have symptoms which may negatively affect not only the patient him or herself but also the other people around which is classified as a violation of one’s freedom and certain right in every individual case. Delusions of the President would negatively affect his decisions making: the decision made in a condition of delusion would be characterized by nonsense, for example, to close all the universities or increase the taxes by 1000 times. Obviously, these ideas are not realistic, but the person with a mental illness would not react to such statements and would go on reckoning that only he or she is right. Hallucinations are also negative things for the person acting as a US President: for example, some decision may be taken properly, but it may turn out to be that the patient with a mental disorder has taken advice from a phantom, not from a real person, and revealing this fact would create concern among the public. Disorganized behavior is also a symptom which makes a person unpredictable: for example, today the President feels excited and makes good presents and treats the people around good, but tomorrow he or she may become very aggressive and apply the behavior model which is not proper for a country leader. Taking the above said into consideration, it is possible to state that there are more cons than pros in the possibility of a mentally ill person becoming the US President, and they all concern the way the other people may be affected by a person subjected to a certain mental illness.
