Coastal Erosion Around the Mediterranean in Dire Need of Governmental Aid

The EU-funded Mare Nostrum Project, which aims to explore new ways of protecting and managing the Mediterranean coastline, called on governments to take immediate and coordinated action to fight cliff erosion.

Mare Nostrum partners met last week in Volos, Greece for a landmark workshop.

One of the most urgent issues to emerge from the meeting was the need for an affirmative and well-coordinated effort to protect cliffs from erosion and collapse.

Representatives of the local authorities of Alexandropoulos, Kavala, Haifa and Netanya all expressed the urgent need for government intervention to tackle the problem.

They emphasized that their cities need major investment for environmental engineering works, but that both national and regional governments are slow to respond.

According to participants, it takes years to draft and approve regulations and to receive national support and financing. Meanwhile, magnificent environmental assets are being eroded away, sometimes even endangering human life.

Everyone talks about climate change and the importance of coastline preservation, but in the meantime the beautiful cliffs of the Mediterranean are endangered by government procrastination,” said Technion Prof. Rachelle Alterman, the initiator and coordinator of Mare Nostrum. “Fighting cliff erosion requires significant investments. We call on all governments in the region to recognize this shared problem and act quickly.”

The risk of coastal erosion is shared by all Mediterranean countries,” Prof. Alterman added. “This issue pertains to the coastline, which should be viewed as national and international asset. Governments should act to meet their obligations as presented by the Integrated Coastline Zone Management (ICZM) Protocol to the Barcelona convention.

Participants of the Mare Nostrum workshop came from universities, municipalities and NGOs in Greece, Spain, Malta, Turkey, Israel and Jordan.

Smith: Zenyatta may be better than last season

Barbara D. Livingston
Saturday's Grade 1 Santa Margarita will be Zenyatta's first start since winning the Breeders' Cup Classic.

ARCADIA, Calif. - Some of the things that Mike Smith says about Zenyatta seem hard to believe.

"It never feels like I've gotten to the bottom of her," he said at Santa Anita on Thursday. "I hope I never have to find out. Other good horses, they've had to give it their all. Even when she's won by a short margin, she's playing, flicking her ears."

Smith has ridden the unbeaten Zenyatta in 11 of her 14 wins, most of which were comfortable victories. She will be expected to win again when she makes her 2010 debut in Saturday's $250,000 Santa Margarita Handicap at Santa Anita. The Grade 1 Santa Margarita will be Zenyatta's first start since her historic win in the Breeders' Cup Classic here last November, when she became the first female to win that showcase race.

The champion older female of 2008 and 2009, Zenyatta will be heavily favored to win the Santa Margarita over 1 1/8 miles on the main track. The race is designed as a prep for the Apple Blossom Handicap at Oaklawn Park on April 9 when Zenyatta is expected to face 2009 Horse of the Year Rachel Alexandra in a greatly anticipated matchup.

RELATED NEWS: Rachel vs. Zenyatta

Smith has been working Zenyatta in the last month, and has noticed a change in the 6-year-old. She seems better than last year, he said.

"I think she's more forward this year than last year," he said. "You might see a big race out of her first time back. If I didn't know better, I'd think she's stronger than last year.

"She's getting to her company really fast and being very aggressive about it. If she does that, we'll see something pretty cool."

Zenyatta will carry top weight of 127 pounds and has eight rivals in the Santa Margarita, the seventh race on a 10-race program that includes the $150,000 San Felipe Stakes for 3-year-olds, the ninth race. The Santa Margarita will be shown on HRTV and streamed live on NTRA.com.

Zenyatta's rivals lack a Grade 1 win among them, but two have won a graded stakes. Pretty Unusual won the Grade 2 El Encino Stakes in January, while Striking Dancer won the Grade 2 La Canada Stakes on Feb. 14. Gripsholm Castle and Floating Heart, second and third in the La Canada, are part of the Santa Margarita field. Dance to My Tune and Made for Magic are stakes winners, Pretty Katherine has been stakes-placed, while Powerofvoodoo, who is not a certain starter according to trainer Barry Abrams, has run in claimers at this meeting.

From any logical perspective, they are unlikely to beat Zenyatta, who wasn't even supposed to be racing this year. After the BC Classic, owners Jerry and Ann Moss said Zenyatta would be retired and bred this winter. They changed their mind on Jan. 16, two days before Zenyatta lost the 2009 Horse of the Year title to Rachel Alexandra.

Zenyatta returned to serious training that weekend, and has impressed trainer John Shirreffs in the last month with her workouts and gallops. He admits to still being a little stung by the Horse of the Year voting.

"What more can a horse do than what she's done over the last two years?" he said. "If they hold her in such little regard, we'll just enjoy it. Because we didn't get Horse of the Year, we don't have the pressure.

"Mr. Moss brought her back to have some fun with her and let the fans enjoy her."

At least 20,000 people are expected at Santa Anita on Saturday, nearly double what the track would draw on a normal Saturday. Many who were in attendance when Zenyatta won the BC Classic, or were here when she was sent off into a presumed retirement during a ceremony on Dec. 26, will be back, with cameras at the ready.

They will be the people packing the garden surrounding the paddock, cheering her name as she is led from the saddling enclosure to the walking ring.

"It's like you're walking with the most popular person at a huge party," Shirreffs said, recalling past moments in the paddock. "There are always people wishing her the best. 'Go get 'em.' She loves it, too. You don't worry what things will make her upset. She's into it."

Uber & TomTom Sign Global Multi-Year Deal For Digital Maps

Written By:

TomTom, the Dutch navigation company, has announced a multi-year contract with Uber where the company will provide digital maps and traffic data for the Uber driver app.

Uber, the ride-hailing company, is present in more than 300 cities over the world, and almost all, of Uber's markets, will receive TomTom's technology. The new technology will enable more accurate arrival time estimates and routes.

Financial terms of the Uber deal are not disclosed, and Uber representatives were heard saying they are looking forward to working with TomTom and declined to comment further.

TomTom's biggest association has been Apple, and both these companies are working together on an in-house mapping app since 2012 when Apple decided to do without Google Maps for its mobile devices.

Earlier this year, Uber was involved in a bidding war for Nokia's mapping business, HERE. Industry sources confirm Uber offered $3 billion; however, lost out to a consortium of German automakers who are seen as long-term competitors to Uber as cars incorporate self-driving technologies.

So disappointed
"I ordered these online and was so bummed when I opened the box. I wanted a more rustic look. These aren't at all. They look like cheap Nine West boots from the 90's, with the cheap looking sole and heel. I didn't even try them on and am taking them back to the store today. :( Darn it."

"I got the gray ones, in the pic they looked pretty cute. i had to exchange them for size8 because the 7 was too tight. I used them a couple of times and they stretch out horribly and the shape is completely lost. Therefore, its low quality material for the price. I wish I had returned them completely instead of getting another size. Sorry DSW but this is the worse product you may have!"

"After reading various reviews on these needing to be sized up, I decided to play it dangerous and get my normal 7 (I always go 6.5 or 7, always 7 for shoes with laces). I have what must be an exceedingly narrow foot as these were perfect when I received them. They are very comfortable and just the right size inside for my foot. I bought the herringbone ones and they are just lovely. While the sole is very comfortable I am slightly skeptical of the sole because of the material (it is just a thick foam like what you may find on the bottom of a slipper or something), but so far so good and I'm not crazy in any of my shoes, so shouldn't be an issue."

Right about this time they should be trickling into the winter wheat and peas..looks like that area will have a week of dry weather and some(light heavy trucks with trailers) fields should be driveable. Note stay off the black dirt roads and don't even think about travelling to the hayfields near the Lakshore and don't even go south near the First Nations Reserve as some black dirt roads are flooded over near the DU walkin site. Many ducks in bigger ponds. Travel only on the gravel grid roads and don't park in the ditches, stay on the approaches..Take car when travelling in an ATV with a shotgun, please read the regulations
and be safe.

Anchor Bay Blu-ray Wrap Up

My Week with Marilyn

My Week with Marilyn is the kind of Oscar baiting project Harvey Weinstein produces in his sleep, and after years of despising such material I was hesitant to care. But despite the period setting, the dead celebrity impressions, and Britonphile themes, I found myself mostly charmed by Simon Curtis’ buoyant, but not too bubbly real life story of aspiring filmmaker Colin Clark (Eddie Redmayne) and his adventures with Laurence Olivier (Kenneth Branagh) and Marilyn Monroe (Michelle Williams). Curtis peppers in just enough era nostalgia and twee quirk to flavour the pot, and does well to keep the story moving at a pace breakneck enough to give a STV action director pause. The tone is sweet without turning sickening, the characters are loveably natural without hamming it up, and the story is shockingly relatable, though it seems to me it would relate more to fans of Monroe and the filmmaking era. My problems with the film mostly revolve around its patently ‘made for BBC’ look and feel. It’s not something I can specifically put my finger on, especially since Curtis manages to successfully mix theatrical breadth with intimate handheld looks, but even the 2.35:1 framing can’t quite make me believe I’m not watching a really good Masterpiece Theatre special. It’s also quite easy to lose track of the secondary characters, especially since the brutal pace doesn’t really allow for an epic number of on-screen personalities. The production probably could’ve done away with Dougray Scott entirely, whose Arthur Miller need only appear in frame to establish his presence, and poor Emma Watson flounders as a most inconsequential love interest. Toby Jones, Judi Dench and Dominic Cooper, on the other hand, manage to really serve the focused tale well with only minutes of screen time. All in all My Week with Marilyn is an entertaining film that doesn’t stretch much deeper, or busy itself with too much subtext (both a curse and a blessing, depending on your mood).

Shot on traditional 35mm My Week with Marilyn looks quite clean, with only a hint of grain to remind us there’s actual film infolved. The colour palette changes up quite a bit throughout the production, switching between soft pastels, harsher painterly warm hues, and natural outdoor greens and browns. The general look is all a bit soft, occasionally even smoky, so superfine details are generally not an issue, but the edges of the more sharply focused shots are basically well cut, with perhaps a touch of haloing effect during the darkest scenes. Blacks are usually tinged with a bit of colour, but remain well packed in terms of crush. The DTS-HD Master Audio 5.1 soundtrack is expectedly simple based on the material, mostly coming to life in the stereo and surround channels for musical moments. There are a few crowd scenes (flashbulbs are LFE heavy) and outdoor ambiences, but this is mostly an intimate, dialogue driven affair. That said, the disc’s producers probably could’ve turned up the volume a bit. The score, which is a mixed effort from composers Conrad Pope and Alexandre Desplat gets a lot of frontal channel work, and even a hair of LFE support in its bassiest throbs. The period jazz music from the likes of Dean Martin and Frank Sinatra fair even better, and are delightfully warm. The extras include a commentary track with director Simon Curtis, and Untold Story of an American Icon (19:10, HD), a behind the scenes featurette.

5 Days of War

When was the last time you even thought about Renny Harlin, let alone enjoyed one of his films? The Long Kiss Goodnight? Deep Blue Sea? Or, like me, do you have to admit a guilty affection for Driven? My point being that even Harlin’s most diehard fans (excuse the pun) have mostly written him off as a has been. According to his latest release, Harlin has fallen below the straight-to-video poverty line, and is making pseudo-propaganda films for Eastern European countries. 5 Days of War (also known as 5 Days of August for its international release) isn’t any kind of revelation, or even a particularly good movie, but as an unabashed fan of Harlin’s brand of cinematic junk food I’m happy to see the guy achieving something just this side of prestigious, at least in terms of visual impression. Harlin employs a bit of the Paul Greengrass shaky-cam approach, but generally speaking his fingerprints are all over the film, specifically in his use of the widescreen frame, and the flow of his cameras. If the estimated $12 million budget listed on wikipedia is accurate, Harlin gets a solid bang for his buck (so to speak), which is impressive following his downfall at the hands of notoriously over-budget flops like Cutthroat Island and Driven. As a director his biggest shortcoming is found in his pacing. Considering the subject matter an epic telling seems appropriate, but generally speaking this would be better served with a taught, 90 minute teardown. Mikko Alanne and David Battle’s screenplay is welcome considering how generally under-covered the Georgian/Russian conflict is, and they’re smart to approach the material from the Western press’ perspective, at least where Western audiences are concerned. Unfortunately, the meat of the conflict ends up lost in the clichéd melodrama of fictional characters, and the intricacies of the politics behind the battling are more or less entirely lost with the heavily Georgian slant, which paints the country as peaceful victims and nothing else (rumour has it that the film was partially funded by the Georgian government). 5 Days of War is an uneasy mix of gung-ho propaganda and Hollywood happy ending bullshit, but will likely find a happy audience among war action fans.

This Blu-ray comes fitted with a solid and sharp 1080p, 2.40:1 transfer that revels in its occasional mixed media approach (Red One digital HD for the bulk of the film, lower res digital for the faux-documentary footage, and even some heavily banded older style video chat footage). Generally speaking Harlin and cinematographer Checco Varese opt for a warm, high contrast look, and lean heavily on golden hues, with poppy green and red highlights. These colours are quite vibrant and remain pure without blocking or major bleeding effects. Detail levels are impressive, especially when Harlin revels in the complex textures of the Georgian countryside. The high contrast blacks look spectacularly deep, and the glowing highlights are smooth, with only minor edge haloes on a couple of the most heavily gold-hued shots. My only real complaint pertains to a handful of ghosting effects. The Dolby TrueHD 5.1 soundtrack is aggressive during times of war, and subtly busy between action beats. The war bits are clearly the most impressive, and run a gamut from extremely bombastic, to punchy, dynamic extremes, and soft, rumbling LFE representations. Trevor Rabin’s musical score actually misses more than it hits with its heavy-handedness, but is warmly and effectively mixed among the more aggressive intensity of war noise. Extras include a deleted scene/b-roll reel (11:00, HD), and Anchor Bay trailers.

Anchor Bay Blu-ray Wrap Up

Sinners and Saints

Sinners and Saints takes place during the hurricane Katrina flood, and ties into the Iraq War, but that’s mostly where the political intrigue and modernity begins and ends. This is just about as generic as a hard R-rated cop thriller can get, featuring nary an iota of unique content to put it beyond its competition. The violence is pretty graphic, even shocking in its take-no-prisoners, any-poor-background-character-could-get-it approach, but never wild or consistent enough to fully impress as anything but a decent imitation of better filmmakers. Co-writer/director William Kaufman has been co-writing and directing indiscernible crime/action films I’ve never heard of since 1999, and clearly has a working knowledge of the cinematic process. He knows how to point and shoot, and though somewhat hyperbolically edited, his action sequences make sense and are nominally thrilling. He’s especially good at shooting precision killers doing their thing crisply and efficiently. However, I’d say Sinners and Saints looks generally sub-television in terms of production value. Breaking Bad, for example, looks more cinematic than anything here. Despite decent performances (Johnny Strong has real B-star charisma, and it’s unfortunate that he disappeared from the acting scene for a decade), none of the characters are memorable, which is especially unfortunate since the film is more character driven than narrative driven. Some of the villains ooze enough grotesque cheer to stand with the best ‘classic’ Steven Seagal and Jean-Claude Van Damme baddies (there’s an amusing hierarchy of villains similar to a video game), but the protagonists are treated like the heroes of a big budget Scorsese flick, and fall spectacularly flat in serious comparison. There is a story, occasional mystery, and couple of amusing one-liners, but I honestly struggle to recall a single outstanding plot point or piece of dialogue. With a touch of comedy, and a more wacky visual sense (I’m thinking something along the lines of Wayne Kramer’s Running Scared) Sinners and Saints might have been an entertaining diversion, but as is I can’t imagine it pleasing anyone outside the most bored and uncritical action lovers.

I can’t find specs to verify if Sinners and Saints was shot digitally or on film, but I’m going to guess Kaufman and cinematographer Mark Rutledge shot 35mm, and digitally tinkered with the colour timing in post. The 1080p, 2.35:1 frame is caked in fine, fluttering grain, the contrast levels are tweaked so high that any semblance of black is crushed to its absolute darkest, and the pallet features almost cartoonish levels of saturation. These harsh colours and unforgiving black and white levels are about as clean as can be expected given the grain levels, and detail levels follow suit, appearing sharpish in close-up, but pretty blown out in medium and wide shots. The bigger problems include weird, jittery frame rate issues during some of the wider establishing shots, and some pretty heavy sharpening artefacts. The Dolby TrueHD 5.1 soundtrack matches expectations with a generally clean and busy sound. The shootouts feature a fair amount of dynamic range, and are reasonably eclectic from sequence to sequence. The stereo and surround speakers play a decent role here, and directional movement is particularly impressive when bullets are flying by characters’ heads, or when the camera angle changes mid shot. I’m not super impressed by this rock, pop, and classical infused score, but it’s pretty good for a first time theatrical composition, and I’m pleasantly surprised to learn the composer in hand was star Johnny Strong. The music is a consistent hum throughout the dialogue sequences, is a bit under-mixed during the action sequences, and makes its best impression when it’s rocking the LFE during montage sequences. There were a few moments I caught the video getting ahead of the sound, but otherwise there’s nothing to complain about here. Extras include Sinners and Saints: Behind the Scenes (3:40, HD), seven deleted scenes (7:00, HD), and trailers for other Anchor Bay releases.

Anchor Bay Blu-ray Wrap Up

Texas Killing Fields

Texas Killing Fields is most notable among those of us that haven’t seen it for two reasons – it is the feature directorial debut of Ami Canaan Mann, daughter of Michael Mann, and it features a pretty great cast for a movie that never got much of a theatrical release. Mann has some of her father in her, but I actually see more or the Coen Brothers and David Fincher influence in this particular film, with perhaps a hint of David Lynch for flavour. The problem is that Mann shares only texture and pacing with these filmmakers, not their quirky sense of visuals, and overall Texas Killing Fields looks a bit made for TV to me. The script, which follows a grizzled police detective and his volatile partner as they investigate a series of murders in Texas, doesn’t do a whole lot to distinguish itself from any number of modern murder mysteries/cop procedural films/TV shows either. At best the story touches upon an eerie sense of inevitability, and at her best Mann picks up on this and presents a lot of the film as a semi-gothic horror story. At worst the story makes no sense, and Mann loses the connections through awkward editing. The A/high B-list cast includes Sam Worthington, Jeffery Dean Morgan, Jessica Chastain, Chloë Grace Moretz, Jason Clarke, and Stephen Graham, most of whom had jobs on much more prestigious and impressive projects in 2011. Everyone has a fun time practicing their Texas accents, and generally maintains an even keel, as if the Texas heat prevents them from emoting anywhere beyond a sigh, except for Worthington, who perpetually yells his way through the film. The characters have humanity, especially Morgan (who deserves a better place in Hollywood right now), but mostly fill out boring tropes, and I found it incredibly difficult to care about any of their personal subplots or interconnections, despite Moretz’s redneck family elements showing the most promise. Too bad Winter’s Bone already got to that well and ruined it for everyone else by being so damn good.

It fortunately appears that Mann doesn’t share her father’s affection for the digital look. She and cinematographer Stuart Dryburgh use digital Panavision Genesis HD cameras, and utilize the system’s grainy, 35mm look to a strong effect. This is a very dark film, generally defined by deep blacks, dry greens, golden browns, soft blues, and red highlights. The colours are consistent and pure, and when intended, plenty vibrant. Details are dependent on the amount of light in a scene, but generally reveal plenty of texture (including that grain), and relatively complex backgrounds. Contrast levels are high and sharp without much edge enhancement. The soundtrack is presented in Dolby TrueHD 7.1 is a bit low on volume and general stuff happening, but generally speaking, impresses with its natural tones. The aural style keeps things smooth and rich, with consistent, light environmental ambience, and even vocal tones. Unfortunately the bulk of the ambience is centered, with only a few pieces escaping into the stereo and surround channels (specifically the omnipresent thunder). There are a handful of effective directional effects, a strong, throbby LFE presence, and Dickson Hinchliffe’s spooky music is given a decent stereo presence. The only extra is a trailer, and trailers for other Anchor Bay releases.

Something Wild: The Criterion Collection

A straitlaced businessman meets a quirky, free-spirited woman at a downtown New York greasy spoon. Her offer of a ride back to his office results in a lunchtime motel rendezvous - just the beginning of a capricious interstate road trip that brings the two face-to-face with their hidden selves. Featuring a killer soundtrack and electric performances from Jeff Daniels (Terms Of Endearment, The Squid And The Whale), MelanieÂ Griffith (Body Double, Working Girl), and Ray Liotta (Field Of Dreams, Goodfellas), Something Wild, directed by oddball American auteur Jonathan Demme (Stop Making Sense, The Silence Of The Lambs), is both a kinky comic thriller and a radiantly off-kilter love story.

Conservatism Bias: How to know what new information to focus on

Traditional finance famously makes lot of incorrect assumptions about how humans make decisions. They assume that we are fully rational, and process infinite information almost instantly.

There’s also a whole wing of behavioral finance that tells us that our brains are simply not up to the task of the modern financial world so we should just quit. We should just admit that we are unfit to manage our affairs and submit wholesale to a passive mentality.

The study of behavioral finance shouldn’t be relegated to the extremes of each view. We demonstrate on a daily basis that we are quite suited to modern life, but we also see bad financial decision on a pretty consistent basis. The point is to understand the circumstances that get us into trouble, optimize decision-making when we can, and avoid the situations when we can’t.

This post is the first in a multi-part series examining different behavioral biases. For each bias, we will break it apart so you can identify it and either correct or avoid it.

This series is as much for our benefit as it is yours. Hope you enjoy and get something out of it.

Bias Class: Believe Perseverance

There is a whole class of biases that can be lumped into the category of belief perseverance (in the face of conflicting evidence). Some people refer to this as “cognitive dissonance.” When evidence changes in relation to an investment decision, we have a choice in how we act. Most people would rather cling to their original beliefs than admit they were wrong. So they resolve the dissonance by cherry picking what sources or information they take in (aka burying their head in the sand) when conflicting information comes their way. Or they tilt the weights of the information so that new information that doesn’t conform to our view can be dismissed or minimized. The phrases, “nobody cares about [insert important development],” or “[important development] is already priced into the market” come to mind.

Conservatism Bias

Conservatism bias has nothing to do with politics. It occurs people maintain their prior view without properly incorporating new information. You consider your original opinion and the information that formed to be quite meaningful, but new information learned after the opinion has been formed is considered to be not as important. The consequence of this is that likely you took action to old information, but aren’t willing to take action on new information that may conflict with it. Rationally when you read this you can see how ridiculous this sounds.

Practical implications: People are more likely to be slow at taking action on new information than they rationally should. Why is this? First, information can be hard to process. Second, truly bad information is sometimes difficult to come to grips with if, especially if you’ve publicly shared your thesis. It means you were wrong and doesn’t feel good at all.

The easy thing psychologically is to see the new information but subtly dismiss it as not important enough to change your original thesis. The hard thing to do is figure out if the information is important and whether you need to take action which might mean changing course and admitting your were wrong.

Fun fact: Let’s say you’re faced with two new pieces of information on the same company. The first piece of new info is easy to understand and explain like changing the company’s product, which is a major consumer good that you understand. The other is an accounting change in the way it tracks inventory. 99% of people will subconsciously weight the information that is easy to understand as more important.

This phenomenon of weighting easy to process info as more important is directly responsible for the problem we see on cable news shows. The only things that people want to discuss are things that can be explained easily in a narrative format. The audience doesn’t want to have complex issues that don’t have a clear answer thrust in their face. Spreadsheet screen grabs are notorious ratings killers. Narrative information is much easier to rationalize into a supporting argument.

But we’re living in a world where there is a constant flow of information spewed at us. How is anyone expected to know if what we’re hearing or reading is useless noise or critically important?

There’s a very simple rule for overcoming the problem of not knowing how to weight information. Ready for it?

Information weighting shortcut rule: If the new information involves math, or is difficult to uncover, verify or explain, ASSUME the weighting of importance is higher than new information you can easily understand.

A heavier weighting does not mean that you instantly take act or assume that it is negative before you analyze the information. It means that the information deserves to be looked at carefully. Especially if there is concurrent new information that is universally considered positive, and has the advantage of being easy to explain released around the same time. The only purpose of this rule is to short circuit the tendency we all have to underweight complex information that has a high mental load and overweight simple narrative information.

When you find yourself ignoring information because it is difficult to understand, you need to either take the time to figure it out or reach out to a professional that can explain what is happening.

Nobody can arrive at a perfectly optimal decision. The goal should be to make less less-bad decisions than everyone else.

Up next: Confirmation bias, representative bias, and illusion of control.

Pre-Term Babies Require Dietary Boost to Strengthen Bones

Health & Fitness

0  Updated at 9:06 am, May 4th, 2013 By: ABC Digital
Share This Story

Photodisc/Thinkstock(NEW YORK) — According to a new study, pre-term infants have different diet requirements than full-term infants.

The study, released by the American Academy of Pediatrics and published in the journal Pediatrics, says that babies born premature require additional calcium, vitamin D, and phosphorus in order to maintain healthy bones. Particularly for babies under 4.4 pounds, breast milk and formula simply aren’t enough.

Researchers recommend preemies receive 200 to 400 IU per day of vitamin D both during and after hospitalization.

The study determined that pre-term babies have unique bone mineral requirements. Because calcium is accreted in large amounts during the third trimester, pre-term births often require a boost to strengthen their bones.

Compressive sensing is a new signal processing paradigm that aims to encode sparse signals by using far lower sampling rates than those in the traditional Nyquist approach. It helps acquire, store, fuse and process large data sets efficiently and accurately. This method, which links data acquisition, compression, dimensionality reduction and optimization, has attracted significant attention from researchers and engineers in various areas. This comprehensive reference develops a unified view on how to incorporate efficiently the idea of compressive sensing over assorted wireless network scenarios, interweaving concepts from signal processing, optimization, information theory, communications and networking to address the issues in question from an engineering perspective. It enables students, researchers and communications engineers to develop a working knowledge of compressive sensing, including background on the basics of compressive sensing theory, an understanding of its benefits and limitations, and the skills needed to take advantage of compressive sensing in wireless networks.

A manual for opening the doors of perception and directly engaging the intelligence of the Natural World

• Provides exercises to directly perceive and interact with the complex, living, self-organizing being that is Gaia

• Reveals that every life form on Earth is highly intelligent and communicative

• Examines the ecological function of invasive plants, bacterial resistance to antibiotics, psychotropic plants and fungi, and the human species

In Plant Intelligence and the Imaginal Realm, Stephen Harrod Buhner reveals that all life forms on Earth possess intelligence, language, a sense of I and not I, and the capacity to dream. He shows that by consciously opening the doors of perception, we can reconnect with the living intelligences in Nature as kindred beings, become again wild scientists, nondomesticated explorers of a Gaian world just as Goethe, Barbara McClintock, James Lovelock, and others have done. For as Einstein commented, “We cannot solve the problems facing us by using the same kind of thinking that created them.”

Buhner explains how to use analogical thinking and imaginal perception to directly experience the inherent meanings that flow through the world, that are expressed from each living form that surrounds us, and to directly initiate communication in return. He delves deeply into the ecological function of invasive plants, bacterial resistance to antibiotics, psychotropic plants and fungi, and, most importantly, the human species itself. He shows that human beings are not a plague on the planet, they have a specific ecological function as important to Gaia as that of plants and bacteria.

Buhner shows that the capacity for depth connection and meaning-filled communication with the living world is inherent in every human being. It is as natural as breathing, as the beating of our own hearts, as our own desire for intimacy and love. We can change how we think and in so doing begin to address the difficulties of our times.

Author Biography

Stephen Harrod Buhner is the senior researcher for the Foundation for Gaian Studies. Described as both an Earth Poet and a Bardic Naturalist, he is the award-winning author of 19 books, including The Lost Language of Plants, The Secret Teachings of Plants, and Sacred Plant Medicine. Before retiring from the road in 2013, he taught for over 30 years throughout North America and Europe. He lives in Silver City, New Mexico.

Putting BCP on Your Holiday To-Do List

By Lisa Smith,
Thursday, November 14th, 2013

We all have “to-do lists,” and we all have our own way of managing how and what gets done. Having BCP on my to-do list is easy; this is what I think about every day and all day. But not everyone has the same responsibility. However, business continuity is like health insurance; it needs to be active. We all need it, but it’s not something we think about every day.Putting BCP on Your To Do List

Disruptions can occur at any time and without warning, which is why we should always be thinking about what we need and how we would respond during a disaster. Let’s not forget the tsunami that hit Thailand in 2004 during the holiday season. Thousands of foreign tourists were in Thailand during that disaster, and many were unaware of the risks within the area, evacuation routes and how to receive assistance.

Cybersecurity Insurance Evolving to Protect Businesses From Increasing Threats

By Kaleigh Alessandro,
Thursday, November 7th, 2013

Last month, former Secretary of Homeland Security Michael Chertoff said the most significant threat we face as a nation is cybersecurity. That’s a pretty jarring statement given the threats our country faces in terms of terrorism and war, for instance. But the reality is, cyber networks have become the gateway for risks both on the global terrorism front as well as within our internal circles at our places of business.Security Headlines
With watchful eyes geared towards security threats, interest in cybersecurity insurance continues to rise. The Department of Homeland Security and the Department of Commerce have identified cybersecurity insurance as a viable opportunity to thwart the effects of security breaches and attacks by:

  • Promoting widespread adoption of preventative measures;

  • Encouraging the implementation of best practices by basing premiums on an insured’s level of self-protection; and

  • Limiting the losses that companies face following a cyber-attack.

Why Hedge Fund Data Center Selection Processes Matter

By Mary Beth Hamilton,
Tuesday, November 5th, 2013

Data center facilities are at the heart of any cloud offering and, as such, are getting more scrutiny as hedge funds evaluate who the right cloud provider is for them.

Earlier this year we created a pretty infograpic that mapped what firms should look for in a colocation facility. Remember this?Hedge Fund Colocation Evauation Map

Since not everyone loves infograpics, we decided to spell out what we look for in a colocation facility. Our due diligence is extensive, but here are some of the high points.

Ownership, Operation & Support: Eze Castle Integration seeks a colocation facility that is owned and operated by a reputable organization with vast industry knowledge and experience. Additionally, the personnel and client support must be of the highest quality in order to ensure that all Eze Castle colocation clients receive the best service and support possible.

Atmospheric Chemistry: Nitrogen Dioxide

The ECN protocol for atmospheric chemistry: nitrogen dioxide (AN)

Protocol file

Site types that use this protocol

Natural and man-made sources emit oxides of nitrogen in approximately equal quantities, but, whilst the former tend to have equal world-wide distribution and are relatively constant over time, the latter are concentrated in or around centres of population.  Nitric oxide (NO) and nitrogen dioxide (NO2) are the most important oxides of nitrogen in urban atmospheres and it is NO2 which has the more significant health and ecosystem effects.  Major sources of NO2 in urban areas result from fuel combustion in motor vehicles, power generation, heating plants and industrial processes, mostly by oxidation of NO emissions from these sources.  NO2 is a respiratory tract irritant, is toxic at high concentrations and is involved in the formation of photochemical smog and acid rain.  It can also cause direct damage to crops and other vegetation, together with SO2 and ozone (UNEP/WHO 1994).  High concentrations of NO2 can have an indirect effect on ecosystems by providing an increased nitrogen input and this is important in the context of systems with a low natural nitrogen demand.

Passive diffusion tubes are used to measure the concentration of Nitrogen Dioxide (NO2).  The tubes are left out for a two-week period.

Crown entity and other statutory board appointments

We manage the process of appointments to a number of Crown entities, statutory boards and advisory boards on behalf of the responsible Ministers. These are important governance roles where members can make a real difference to education both nationally and internationally.

Current board appointments

Apply for a position on the Tertiary Education Commission (TEC) board - applications open 20 February and close 13 March 2013.

Board appointments process

We assist responsible Ministers in identifying candidates who have the required skills and experience for a board role. In general, board members must have an appreciation of the Crown’s role as the key stakeholder as well as meeting key competencies that apply to the position.

Boards also need to represent the diversity and demographic makeup of New Zealand.  To ensure this we encourage individuals as well as government agencies, community organisations and industry bodies to submit nominations.

We assist with appointments to the following boards:

Statutory appointments are made by the responsible Minister, or the Governor-General on the recommendation of the responsible Minister.  The Minister must present candidates to the Cabinet Appointment and Honours Committee.

If you have been nominated for a position, the outcome of the process cannot be confirmed until after appointments have been considered by the Cabinet Appointment and Honours Committee and Cabinet.  This is likely to be several months after your nomination was submitted.

Public servants are not usually appointed to statutory boards. The Cabinet Office circular CO (02) 5 Appointment of Public Servants to Statutory Boards [PDF; 55kb] has further information.

Board members are paid fees, according to the board’s roles and responsibilities.  Education Crown board fees are set by Ministers using the Cabinet Fees Framework.  This document is reviewed periodically.

Create Activities For Children About Maps Using Google Maps

No matter what subject you're teaching in the classroom, there is always a place for activities for children about maps. If you want to describe mathematics, you can teach students about calculating distances and elevations, or converting units. If you are teaching history, you can use maps to show how different areas change over time. Even if you're teaching a subject like literature, maps can let you experience stories by exploring the places where those plots are set.

A map is a unique tool that you can use for a whole multitude of purposes. Google Maps itself is a perfect resource for a lot of these activities, but in some cases, Google Maps doesn't offer all of the features of functionality that you might need for certain subjects, like diving into the science behind climate, or exploring important social issues like population.

Thankfully, in addition to Google Maps, there are also websites that offer what are called "Google Maps Mashups", which are essentially additional tools that have been "mashed up" with Google Maps to provide a bit of added functionality or information to Google Maps. Some of these mashups are wonderfully creative, and extremely useful in a classroom environment.

The following list includes six creative ideas for activities you could do with your children in the classroom using either Google Maps, or a Google Maps mashup.

Google Maps

When most people think of Google Maps, they think of trying to get driving directions to some destination. However, there's a lot more to Google Maps than just simple navigation.

For example, if you want to research an area of the world with your students, Wikipedia is often an excellent resource. Luckily, Google Maps has incorporated a Wikipedia layer, so that you can actually access Wikipedia articles that apply to the region of the world that you're viewing with Google Maps.

activities for children about maps
The Wikipedia Layer on Google Maps

This is an excellent way for students to do research about a region in a format that allows the student to see where those articles and the described history geographically applies.

This can not only help students learn more about world history in a way that is interesting and fun, but it also improves geography skills so that students will more easily recognize regions throughout the world much more easily.

activities for children about maps
Wikipedia Articles on Google Maps

Whenever you hover your mouse over any of the Wikipedia icons on the Google Map, you'll see a pop-up excerpt of the article about that area. If you want to read more, all you have to do is click on the "Full Article" link.

You'll find that nearly every inch of the world is populated by interesting and informative Wikipedia articles. It's like your personal tour guide for that part of the world.

Another similar method to explore the world without the need to spend a fortune on field trips is to use the "Photo" layer on Google Maps. Enabling the photo layer will show all of the photos that other people have taken and posted to Google Maps while visiting that part of the world.

Great Pyramids on Google Maps

What better way to learn more and see more of the natural, beautiful wonders of the world than to browse through the sort of photo slideshows that you can find on Google Maps?

In the area of Mashups, one of the best is HealthMap. The motto of the site is "Global Health. Local Knowledge." This is because through learning about global healthy issues and epidemics, students can learn more about how local communities around the world need to respond to the threat of disease and other health issues.

The HealthMap mashup overlays recent, breaking health events, such as where clusters of diseases or outbreaks have occurred.

The HealthMaps Mashup

Each pin on overlaid on top of the Google Map represents a health event. By clicking on any of the pins, you'll see a pop-up that provides the date of the event, and other details such as the specific disease or illness, the location, and sometimes the source of the information.

The very bottom of the main HealthMap page lists hundreds of the most recent alerts, which you can scroll through to learn more about the latest disease outbreaks and health crisis throughout the world.

Flood Maps

If you're teaching your students about climate change, one great Google Maps mashup to use is the Sea Level Rise map.

This tool lets you move to any continent in the world by clicking on one of the links at the top of the page. Then, change the sea level rise dropdown from 0 meters up to 60 meters, and watch how such a sea level rise will impact coastlines and islands all around the world.

world maps for children
The Sea Level Rise Map

The nice thing about this Google Map mashup is that you can zoom right in to local areas, and observe how sea level rises might impact local communities. Students will be fascinated to see how towns and cities that they might have visited would be virtually wiped off of the map by the rising ocean waters.

This exercise would do well followed by an examination of climate predictions, and what scientists say may be the reasons for these dramatic climate changes.

Cloud Maps

Another great resource for a science class where the discussion may be different cloud types, would be DaylightMap.com's Clouds mashup.

This tool shows weather patterns over the entire world using data from Google Earth's weather layer, NASA's Earth Science Office, and xplanet's cloud layer.

maps for children
Watching the Clouds

The amazing thing about this map is that it is regularly updated, so that the clouds you and your students are observing very likely looked like that no more than six hours in the past.

This is a great tool to use to observe cloud patterns with kids, and to teach them how to identify cloud types, not only from the ground but from overhead satellite photography such as this.

Earthquakes in the Last Week

A fascinating Google Maps mashup to explore with students is the Earthquakes Last Week tool.

This website overlays an Earthquake marker layer onto Google maps, with marker types showing the magnitude of earthquake that took place at that location within the past week.

activities for children about maps
Viewing Recent Earthquakes

All of the earthquakes featured on this map are from the last seven days, so students can expect to see markers for many earthquakes that they've probably even read about in the news.

This is an excellent tool to use when you are teaching your students about the Earth's fault lines, volcanoes and interactions between elements of the planet Earth itself.

As you can see, maps can prove to be an invaluable educational tool if they are applied in concert with other educational materials in the classroom. Google Mashups maps are particularly useful, because they give students a view of the world in an interactive way that will hopefully make the lesson more memorable.

Magnet schools alone may not help school districts meet diversity goals in areas where districts were released from court-ordered school desegregation plans, suggests a study published in the Education Policy Analysis Archives.

The study—conducted by researcher Emily Arcia of the Miami-Dade County Public Schools—examined that school system, a 350,000-student urban district that had been released from a court-ordered desegregation plan. The study compared enrollment statistics for magnet and nonmagnet schools in the district in the year it was released from court-ordered desegregation and four years later. The study found that within four years of the release, gains the magnet schools had made in black and white student integration had been lost.

Fickle winds, intermittent sunshine start to stress U.S. power system

The growth of U.S. wind power has begun to create operating challenges for nuclear and coal plants that must be ramped up and down as wind speeds vary, panelists at a Massachusetts Institute of Technology energy conference reported last week.

The MIT Energy Initiative symposium on integrating large-scale wind and solar power attracted executives of utility and transmission companies, senior government officials and academic researchers, whose comments were off the record. Some papers prepared for the conference were made public by their authors, and they define a growing challenge of matching the current U.S. mix of power plants with new requirements to respond quickly to changes in wind and solar resources.

"The power system needs more flexibility to handle the short-term effects of increasing levels of wind," said Ignacio Pérez-Arriaga, a professor at Spain's Comillas University and a visiting professor at MIT.

He and other speakers predicted the expansion of renewable power will continue as a clear option for reducing power plant carbon emissions. Nearly half of global electricity supply will have to come from renewable sources if world carbon dioxide emissions are to be cut to half of current levels by 2050, according to the International Energy Agency, he noted.

But utility regulation has not adapted to a future of high renewables, he warned. And a high penetration of wind and solar generation is likely to make wholesale electricity prices more volatile. These and other potentially disruptive issues "raise concerns about attracting sufficient investment in ... flexible plants" in competitive power markets, he said.

A paper by the Brattle Group says the expansion of renewable energy requires "more generation ... that can quickly ramp up and down, possibly with short start-up times and minimal cool-down times." Whether those needs for more cycling and peaking energy can be met by existing generators is not clear and must be given detailed study, the Brattle Group paper says.

Regulation, finance and operational changes needed

In the United States, the drop in demand for power that began with the recession in 2008 has left spare generation capacity that can be used to balance power supply to demand in this decade. But regulation, capital investment policies and operating practices all must change to maximize that potential, speakers said.

And right now, the difference in the peak demand for daytime power is growing in the United States, adding to the need for a more flexible system. Grid operators must plan for a future worst-case scenario of several consecutive days with very low wind and solar power coinciding with very high summer power demand, Pérez-Arriaga said. This is a key challenge in designing the long-term generation mix.

A major focus of the April 20 symposium was the impact of more frequent start-stop cycling of coal-fired generators, as they are called on to balance peaks and valleys in wind output.

Putting coal plants on a more rapid cycling schedule exposes valves, piping and other components to more extreme temperature shifts and potentially damaging changes in steam operation chemistry, said Steve Hesler, a program manager at the Electric Power Research Institute, in a conference paper. These can accelerate wear and tear and induce corrosion and stress, raising the risks of cracking and failure of metals and welds, he noted.

Hesler said that increased cycling of coal plants is already evident, resulting from the recession-caused drop in power demand, lower natural gas prices, and expansion of renewable generation. The bulk of the balancing services from U.S. coal plants is being met by smaller units built before 1970 that are typically run at relatively low capacities, rather than newer and larger coal plants whose owners run them as much possible to supply baseload power, Hesler wrote.

The smaller, older plants are most at risk from U.S. EPA regulation and competition from natural gas generation that currently benefits from low gas prices. As these older coal plants are retired, current flexibility of the generation fleet is likely to suffer, speakers said. "We're running out of flexible coal units," one participant said. "The newer plants aren't built well enough to do load following" in response to variations in renewable energy output.

"I can't imagine owners of coal plants ... making significant capital investments around ramping," said another participant.

Who pays for needed adjustments?

Both large coal units and nuclear plants are intended to be run full time, and the utility industry has spent decades training operators to do that. If they now are required to run the plants at varying outputs to respond to ups and downs in renewable energy, the risk of human error may rise, one conference participant said. "I'm sure they'll get there, but the human factor is not be underestimated."

Another participant said that manufacturers have designs for faster-responding gas-fired generators that would be better suited to handle the temperature and pressure stresses of ramping operations. But the industry has not seen utilities "rushing to the door" to purchase more adaptable but more expensive generators. "It's an economic decision."

The regulation of the U.S. electric power industry is still aimed at securing power at the lowest cost. But the changes in store for the power sector won't come for free, one speaker said. "There is no way we can accomplish this at a lower cost. So the question is, who pays?"

Officials of the American Wind Energy Association sparred with a representative of the Bentek Energy consulting firm, who presented a new analysis, "The Wind Energy Paradox." It asserts that increased wind energy output forces coal generation into inefficient start-stop operations that increase emissions of nitrogen- and sulfur-oxide pollutants.

To the extent that wind power will be backed up by gas-fired generators rather than coal, the gains in carbon emission reductions from wind are diminished, the Bentek report says.

The paper says that the increase in pollutant emissions caused by frequent cycling of coal- and gas-fired generation undermines the wind industry's claims about the emission reduction benefits from renewables. "It's not a very cost effective way" of saving carbon, SOx and NOx, the sulfur and nitrogen oxide pollutants, the report says.

AWEA responded via email, "There are more than two dozen different peer-reviewed wind integration studies from the U.S. and Europe, mostly by utilities. They show that the U.S. can accommodate a lot more renewable generation than we have today, at relatively modest integration costs and with significant emissions reductions."

"Similarly, their [Bentek's] model only looks at hourly snapshots and would therefore exclude the vast majority of the emissions savings caused when wind energy causes emitting sources to turn off for an extended period of time," AWEA said.

"The Bentek report overstates coal cycling costs and impacts by extrapolating from an extreme case of ramping a generator down from 100 to 40 percent of capacity in an hour which almost never happens. While it is fair to incorporate coal ramping costs and impacts, the study greatly overstates those impacts and does not reflect the way generators are committed and dispatched by grid operators," AWEA said.

'Fractured decisions' expected from states and regions

The conference concluded with the question of whether the patchwork of federal and state regulation and the stalemate over national climate and transmission policies in Congress would help or hinder a transition to more renewable power.

"Considerable progress" is being made by the Federal Energy Regulatory Commission, state regulators, regional transmission organizations and utilities in planning to accommodate more renewable power, tuning market incentives to create a more flexible system, and fairly allocating costs for this transition, the Brattle Group report says.

The reality is that states and regions will have the most to say about this process. "We do not see any grand, unifying theory of cost allocation for the costs of renewable variability, nor do the institutional differences, legacy generation, or indigenous resources across regions of the U.S. ... lend themselves to uniform solutions," the report says.

"While the road ahead may be contentious and laborious, there seems to be no technical or economic reason why a well-functioning regulatory system cannot find its way to a sustainable, reliable and economical destination."

Other conference participants were far less optimistic that a divided Congress and White House can rationalize climate and energy policies.

A larger, more sophisticated transmission network, including long-haul high-voltage direct-current lines, would expand the footprint for solar and wind generation, smoothing the daily and hourly variations in renewable energy output, speakers noted.

One industry executive said that many papers submitted to the conference assume that a stronger inter-regional transmission network would ease the integration of renewable power into the grid. With some exceptions, notably in Texas, that goal faces huge political and industry opposition, the speaker said.

"We have no right to that assumption in the U.S., and we shouldn't make it. We should assume instead we will be making fractured decisions."
