saco-indonesia.com, Apabila sekarang ini mayoritas perangkat mobile telah menggunakan produk dari Corning yaitu Gorilla Glass, ada pula rumor bahwa akan dibuatnya layar berbahan safir. Kali ini muncul berita serupa yaitu layar berbahan kulit kerang.
Para peneliti dari McGill University, Kanada, ingin mencoba mengembangkan sebuah layar yang tahan banting dan benturan. Para peneliti tersebut telah terinspirasi dari kekuatan kerang.
Dikutip dari Cnet (30/01), para peneliti tersebut juga menjelaskan, "Kerang moluska telah memiliki lapisan luar yang boleh terbilang rapuh, namun apabila jika dibandingkan dengan bagian dalamnya, maka sangat berbeda, karena sangat kuat."
Oleh karena itu, para peneliti yang telah dipimpin oleh Profesor Francois Barthelat itu ingin mencoba meneliti dan meniru lapisan demi lapisan termasuk juga jaringan yang terdapat pada kerang untuk dapat diaplikasikan ke sebuah layar anti-bentur.
Barthelat juga berharap nantinya apabila penelitian yang dia lakukan bersama tim-nya itu akan berhasil, maka tidak hanya di perangkat mobile saja , penemuannya itu dapat juga digunakan di banyak hal.

DPRD DKI Disinyalir Dinas PU Korupsi Miliaran Rupiah
Komisi D DPRD DKI Muhammad Sanusi mengungkapkan, pihaknya menemukan anggaran pos tak terduga
sebesar Rp 300 miliar di Dinas Pekerjaan Umum DKI.
Indonesia.com — Anggota Komisi D DPRD DKI Muhammad Sanusi mengungkapkan,
pihaknya menemukan anggaran pos tak terduga sebesar Rp 300 miliar di Dinas Pekerjaan Umum DKI.
Menurutnya, hal itu berpotensi dikorupsi.
Ditemui di kantornya, Selasa (4/6/2013)
pagi, Sanusi mengungkapkan, temuan dana itu didapat saat Komisi D DPRD DKI melakukan rapat
kerja dengan Dinas PU DKI dan sejumlah pejabat lain. Menurutnya, Dinas PU memiliki dana
paling besar dari dinas lain di Pemprov DKI, yakni Rp 7 triliun.
penyerapannya rendah sekali. Dana tidak terprediksi atau sewaktu-waktu ada Rp 300 miliar. Ini
sangat mungkin dikorupsi," ujar Sanusi.
Sanusi menjelaskan, potensi korupsi
yang bisa terjadi adalah melalui proyek tambal sulam jalan di DKI. Dengan dana tersebut, Dinas
PU dapat sewaktu-waktu menjalankan proyek tambal sulam sejumlah jalan berlubang di DKI
Jakarta tanpa perencanaan akurat sebelumnya.
"Misalnya jalan bolong
dikit ditambal dan bolong lagi. Ini kan jadinya proyek terus. Harusnya enggak boleh,
mereka harus bisa prediksi jalan kapan habis masanya, baru itu benar," tutur Sanusi.
Sanusi menilai, persoalan ini harus ditangani oleh Gubernur DKI secara langsung. Jangan
sampai, keberhasilan Joko Widodo dan Basuki Tjahaja Purnama tercoreng dengan penyerapan
anggaran rendah hanya pada Dinas Pekerjaan Umum DKI Jakarta.
telah berusaha mengonfirmasi hal tersebut kepada Kepala Dinas Pekerjaan Umum DKI Manggas Budi
Siahaan. Namun, ponsel yang bersangkutan tak kunjung tersambung.

How Some Men Fake an 80-Hour Workweek, and Why It Matters
Imagine an elite professional services firm with a high-performing, workaholic culture. Everyone is expected to turn on a dime to serve a client, travel at a moment’s notice, and be available pretty much every evening and weekend. It can make for a grueling work life, but at the highest levels of accounting, law, investment banking and consulting firms, it is just the way things are.
Except for one dirty little secret: Some of the people ostensibly turning in those 80- or 90-hour workweeks, particularly men, may just be faking it.
Many of them were, at least, at one elite consulting firm studied by Erin Reid, a professor at Boston University’s Questrom School of Business. It’s impossible to know if what she learned at that unidentified consulting firm applies across the world of work more broadly. But her research, published in the academic journal Organization Science, offers a way to understand how the professional world differs between men and women, and some of the ways a hard-charging culture that emphasizes long hours above all can make some companies worse off.
Ms. Reid interviewed more than 100 people in the American offices of a global consulting firm and had access to performance reviews and internal human resources documents. At the firm there was a strong culture around long hours and responding to clients promptly.
“When the client needs me to be somewhere, I just have to be there,” said one of the consultants Ms. Reid interviewed. “And if you can’t be there, it’s probably because you’ve got another client meeting at the same time. You know it’s tough to say I can’t be there because my son had a Cub Scout meeting.”
Some people fully embraced this culture and put in the long hours, and they tended to be top performers. Others openly pushed back against it, insisting upon lighter and more flexible work hours, or less travel; they were punished in their performance reviews.
The third group is most interesting. Some 31 percent of the men and 11 percent of the women whose records Ms. Reid examined managed to achieve the benefits of a more moderate work schedule without explicitly asking for it.
They made an effort to line up clients who were local, reducing the need for travel. When they skipped work to spend time with their children or spouse, they didn’t call attention to it. One team on which several members had small children agreed among themselves to cover for one another so that everyone could have more flexible hours.
A male junior manager described working to have repeat consulting engagements with a company near enough to his home that he could take care of it with day trips. “I try to head out by 5, get home at 5:30, have dinner, play with my daughter,” he said, adding that he generally kept weekend work down to two hours of catching up on email.
Despite the limited hours, he said: “I know what clients are expecting. So I deliver above that.” He received a high performance review and a promotion.
What is fascinating about the firm Ms. Reid studied is that these people, who in her terminology were “passing” as workaholics, received performance reviews that were as strong as their hyper-ambitious colleagues. For people who were good at faking it, there was no real damage done by their lighter workloads.
It calls to mind the episode of “Seinfeld” in which George Costanza leaves his car in the parking lot at Yankee Stadium, where he works, and gets a promotion because his boss sees the car and thinks he is getting to work earlier and staying later than anyone else. (The strategy goes awry for him, and is not recommended for any aspiring partners in a consulting firm.)
A second finding is that women, particularly those with young children, were much more likely to request greater flexibility through more formal means, such as returning from maternity leave with an explicitly reduced schedule. Men who requested a paternity leave seemed to be punished come review time, and so may have felt more need to take time to spend with their families through those unofficial methods.
The result of this is easy to see: Those specifically requesting a lighter workload, who were disproportionately women, suffered in their performance reviews; those who took a lighter workload more discreetly didn’t suffer. The maxim of “ask forgiveness, not permission” seemed to apply.
It would be dangerous to extrapolate too much from a study at one firm, but Ms. Reid said in an interview that since publishing a summary of her research in Harvard Business Review she has heard from people in a variety of industries describing the same dynamic.
High-octane professional service firms are that way for a reason, and no one would doubt that insane hours and lots of travel can be necessary if you’re a lawyer on the verge of a big trial, an accountant right before tax day or an investment banker advising on a huge merger.
But the fact that the consultants who quietly lightened their workload did just as well in their performance reviews as those who were truly working 80 or more hours a week suggests that in normal times, heavy workloads may be more about signaling devotion to a firm than really being more productive. The person working 80 hours isn’t necessarily serving clients any better than the person working 50.
In other words, maybe the real problem isn’t men faking greater devotion to their jobs. Maybe it’s that too many companies reward the wrong things, favoring the illusion of extraordinary effort over actual productivity.
Ghostly Voices From Thomas Edisonís Dolls Can Now Be Heard
Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.
The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.
In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.
Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.
Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.
The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.
In 2014, the technology was made available for the first time outside the laboratory.
“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”
Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.
The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.
“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.
The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.
Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.
Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.
At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.
Recently, the conservation center turned up another surprise.
In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.
Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.
“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.
The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.
