National Parks Featured In IMAX Movie & TV Series
Dozens of national parks will be featured in an upcoming IMAX 3D film that is scheduled to be released in early 2016.
On February 12, 2016, a new giant screen film, “National Parks Adventure”, will be released around the world, and will feature narration by Robert Redford.
Produced by MacGillivray Freeman Films along with Brand USA, the destination marketing organization for the United States, the film follows mountaineer Conrad Anker, his stepson Max Lowe, and family friend Rachel Pohl as they explore the beauty and natural wonders of parks like Rocky Mountain, Devils Tower, Katmai, Canyonlands, Everglades, Congaree, Redwood, Yellowstone, and more. Many national parks helped make this filming possible.
Produced as a tribute to the National Park Service’s Centennial, the film also journeys back to the early days of the parks, recreating John Muir and Theodore Roosevelt’s famous three-day camping trip in Yosemite.
The film is the centerpiece of Brand USA’s Great Outdoors campaign, which promotes America’s lands and waters to international visitors.
While shooting “National Parks Adventure”, MacGillivray Freeman also produced an eight-part TV series in collaboration with the Travel Channel called, “America. The Beautiful.” The series is also narrated by Robert Redford and features parks, national forests, state parks, and a variety of public lands and waters. The series began airing on the Travel Channel last month. The series will likely air again in February 2016 with the release of the IMAX film.
MacGillivray Freeman has been making large screen films for fifty years, with 38 films to date, including award winners such as “Everest,” “The Living Sea,” and “To Fly.” Their films frequently focus on the natural world, inspiring audiences to both explore and protect natural resources, and each film is accompanied by uniquely designed educational outreach programs that broaden the film-going experience for students.
Below is a short overview of the movie:

Quick Tips for Viewing Elk Safely
Though they may look docile, elk are large animals capable of covering large distances quickly. Armed with sturdy antlers and powerful hooves, these animals can be very aggressive and dangerous during the fall breeding season, known as the rut, which usually takes place during the months of September and October. Find out what simple precautions you should take while viewing elk in this short video from the Great Smoky Mountains Association:

How to Climb (hike) a Mountain
Below is a short video that was featured on Outside Today a few years ago. Although the title of the video was "How to Climb a Mountain", the skills discussed in this video are actually basic mountain climbing skills that most hikers will benefit from, and should have an understanding for safer passage through the mountains. The video features Rainbow Weinstock from the Colorado Mountain School:

Additional Emerald Ash Borer Found in Shenandoah National Park
Shenandoah National Park staff have confirmed additional infestations of emerald ash borers (EAB) in the park. Adult EAB beetles were caught in surveillance traps near Mathews Arm Campground, Gravel Springs Hut, Pinnacles Picnic Area, Big Meadows Picnic Area, and South River Picnic Area. These new finds represent a significant jump from last year’s detections in the northernmost portion of the Park (Warren County) and near Park Headquarters in Page County. They also represent detections in three new Virginia counties including Rappahannock, Rockingham,and Madison.Park Superintendent Jim Northup stated, “It appears that the emerald ash borer is moving fairly rapidly through the Park from North to South, faster than our staff anticipated.This is a sad reminder of how hard it is to maintain ecological integrity, even in our National Parks.”
The emerald ash borer is a half-inch-long metallic green beetle that lays eggs on the bark of ash trees. After hatching, the EAB larvae burrow under the bark and create feeding tunnels that cut off nutrient and water flow to the tree. As a result, ash trees typically die within three to five years. EAB was accidentally introduced to North America from Asia and was first discovered in southeast Michigan in 2002 on infested wood packaging material. Since its introduction, EAB has spread to 25 states and two Canadian provinces, killing over 50 million ash trees.
Ash trees represent a significant component of Shenandoah National Park’s ecosystems. Five percent of the trees in the Park are ash. This may not sound like a lot; however, ash trees are found throughout the Park and occur in 16 of its 34 vegetation communities. Collectively, these ash-containing communities make up 65% of the Park’s forest (126,883 acres). If EAB becomes well established in Shenandoah, it could lead to upwards of 95% ash mortality.
Since the EAB is a nonnative pest, the Park is mandated to minimize its impacts on native ash trees. In April 2013, staff began conducting preventive EAB pesticide treatments on ash in developed areas and select sensitive plant communities in the northern third of the Park. Every year since, Park staff have conducted treatments in the North District and this year now include portions of the Central District. The project goals are to reduce hazard ash tree formation in developed areas and to preserve a portion of the Park’s ash trees until approved biological controls become available. Park staff treated 1,030 ash trees inspring 2015. The treatment window for effective EAB suppression in the Park is April and May. Complete eradication of EAB is not currently feasible, but Park managers are taking these actions to maintain public safety and to protect ash trees where possible.
EAB and other exotic forest pests can be transported via firewood. To minimize this pathway of introduction, Park regulations only allow heat-treated firewood (USDA approved) and firewood that is collected within the Park.

Hillgrove Monzogranite
Hillgrove is known for its mining history. The fortunes of the place have been directly related to gold and antimony mining for more than a hundred years. In fact nearby Armidale was a village in comparison with Hillgrove at its peak. Hillgrove still operates a mine for antimony and gold but is now quite a sleepy place with a handful of inhabitants. Most people working at the mine commute from Armidale. But the mine itself is not what I want to write about, it is about the attractive rock that is known as the Hillgrove Monzogranite. Despite its name the Hillgrove Monzogranite is not the extensive source of gold and antimony that is mined in the area. Most of the ore mineralisation is either directly or indirectly related to the nearby Bakers Creek Diorite.
| Hillgrove Monzogranite on the Waterfall Way |
Monzonite is unsurprisingly the dominant rock type of the Hillgrove Monzonite. It is an S-Type granite (derived from melted sedimentary rock). It is comprised mainly of quartz and feldspars (roughly equal potassium feldspar and sodium-calcium Feldspar), quartz, biotite mica and hornblende. The biotite often shows a foliation, which is a preferred alignment in the rock. The age of the Hillgrove monzogranite is estimated at between around 270 to 290 million years. To my knowledge, the age has not been directly measured but instead is based on its relationship to the surrounding rocks with their either calculate or approximate ages.
The landscape formed by the Hillgrove Monzogranite is one of my favourites. It forms a relatively large plateau which is contains low rolling hills and lovely boulder outcrops. These outcrops often form lovely torrs (see pictures) formed by “onion-skin” weathering. Water enters cracks in the rock and during winter this freezes and expands gradually wedging the layers off the boulder. This is correctly termed frost wedging.
The Bakers Creek gorge has cut into some of the unit near the Hillgrove area but overall the appearance of the country is quite gentle. The rock unit extends a long distance from the location of Argyle in the west almost to Chandler Gorge in the east. The Waterfall Way (Armidale-Dorrigo Road) crosses in and out of the Hillgrove Monzogranite and Girrakool Beds into which it has intruded. Therefore it is an easy stop on the road when travelling this route.
The soils are sandy and not very fertile leading to an area used for cattle and sheep grazing on native and improved sown pastures. The forest is the open dry sclerophyll ?????????snow-gum type bush which is one of the typical environments of the New England high country. I love the appearance of this country. It is the quintessential high-lean New England landscape.
RELIGIONS : Crois ou meurt !
Salut à tous,
Le Huffington Post Québec : Des millions de personnes soutiennent Raif Badawi, mais qui se soucie d`un pauvre jeune Mauritanien ?
¨ Au cours du mois de décembre 2013, un jeune blogueur mauritanien Mohamed Ould Cheikh M'Kheitir, 30 ans, a publié un article intitulé «Religions et Religiosité» dans lequel il défendait le droit de son peuple «artisan» en Mauritanie, utilisé et exploité au prétexte de son histoire récente de peuple esclave.
Dans son article, Mohamed Cheikh évoque le système du « deux poids, deux mesures » utilisé par le prophète Mahomet lui-même lorsqu'il traitait avec les Juifs et avec les Arabes; et explique que le prophète tuait les Juifs, mais pardonnait aux Arabes parce qu'ils sont du même sang.
Mohamed Cheikh a tenté de démontrer dans son blogue comment la religion agit en matière de hiérarchie sociale et de discrimination entre les classes sociales. Des gens sont sortis dans les rues de Mauritanie pour manifester contre l'article en criant « Mort au blogueur ». L'article a été considéré comme un blasphème envers le prophète, car il le dépeignait comme une personne injuste, qui préfère sa tribu à d'autres tribus.
Les autorités l'ont arrêté le 2 janvier 2014 et il a été présenté devant le tribunal en décembre 2014, pour y être condamné à mort le jour même. Avant l'annonce de la sentence, Mohamed Cheikh a prononcé la Shahada, indiquant ainsi clairement qu'il était musulman, et a expliqué que son intention n'était pas de critiquer le prophète Mahomet. Il a présenté ses excuses pour avoir écrit ce texte. Le juge n'a pas rien retenu de ses paroles et a prononcé la sentence de mort. Selon l'Agence France-Presse, Mohamed Cheikh, s'est «évanoui lors de la lecture du verdict, a été ranimé, puis reconduit vers la prison».
Des millions de personnes à travers le monde se sont ralliés à l'appui de Raif Badawi, mais qui prendra soin d'un pauvre jeune homme en Mauritanie? Il sera exécuté pour blasphème par ceux qui affirment que l`État islamique ne représente pas l`Islam !!! (Voir l`article au complet)

The Largest Wildfires in U.S. History
Several major wildfires raging across the west have grabbed headlines around the world in recent weeks. So far this year more than 39,000 wildfires have burned nearly 6.4 million acres in the United States. The number of wildfires this year represents about 80% of the ten-year average. However, the number of current acres burned represents a roughly 38% increase over the ten-year average at this point in the year. At more than 330,000 acres, the largest wildfire currently burning in the U.S. is in central Alaska. There are three other significant wildfires of note, the Soda Fire in Idaho, the Comet-Windy Ridge Fire in Oregon, and the Chelan Complex in Washington, which are currently burning more than 283,000, 103,000, and 69,000 acres, respectively.
As a result, the National Multi-Agency Coordinating Group increased the National Fire Preparedness Level to its highest point last week.
Having looked at the current situation, I wanted to see where these fires stood when compared to the largest wildfires in U.S. history. The following are the top 10 largest wildfires in U.S. history, none of which include any of the fires currently burning:
1) The Great Fire of 1910: 3,000,000 acres - Killed 86 people, including 78 firefighters in Idaho, Montana and Washington. The fire destroyed enough timber to fill a freight train 2,400 miles long.
2) The Great Michigan Fire (1871): 2,500,000 acres - The Great Michigan Fire was a series of simultaneous forest fires that were possibly caused (or at least reinforced) by the same winds that fanned the Great Chicago Fire. Several cities, towns and villages, including Holland, Manistee, and Port Huron suffered serious damage or were lost.
3) Taylor Complex Fire (2004): 1,305,592 acres - The Taylor Complex Fire in Alaska was the largest wildfire by acreage during the 1997–2007 time period.
4) Peshtigo Fire (1871): 1,200,000 acres - The Peshtigo Fire in Wisconsin killed over 1,700 people and has the distinction of causing the most deaths by fire in United States history.
5) Silverton Fire (1865): 1,000,000 acres - Oregon's worst recorded fire.
6) Thumb Fire (1881): 1,000,000 acres - Killed more than 200 people in Michigan.
7) Yellowstone (1988): 793,880 acres - The Yellowstone fires of 1988 in Wyoming and Montana were never controlled by firefighters. They only burned out when a snowstorm hit in early September. A whopping 36% of the park was affected by the wildfires.
8) Long Draw Fire and Miller Homestead Fire (2012): 719,694 acres - Oregon's largest fire in the last 150 years.
9) Murphy Complex Fire (2007): 653,100 acres - The fire was a combination of six wildfires caused by lightning in south-central Idaho and north-central Nevada that started on July 16–17, 2007.
10) Siege of 1987 (1987): 650,000 acres - These fires were started by a large lightning storm in late August, burning valuable timber primarily in the Klamath and Stanislaus National Forests.

My Top 11 Tips For Beginner Cyclists
As you're probably already aware, this blog is primarily focused on hiking. However, when I'm not out on the trail, my favorite form of exercise is cycling. I've been riding on a regular basis (5 or 6 times a week) for almost 30 years. At a family gathering a few weeks ago my brother-in-law announced that he was going to take up cycling. As a result, I was inspired to write this blog and impart some advice to him, and anyone else who's thinking about taking up this wonderful sport, or anyone who's recently caught the bug.
To help newbies dive into the sport, the following are my top 11 tips for beginner cyclists:
1) Buy the right bike (Part 1): Before dipping your toes in, the first thing you need to consider is what kind of bike to purchase. The answer to that question will be determined by what kind riding you plan to do: off-road trail riding, dirt/gravel roads, cruising around the neighborhood, or venturing out to do one or two-hour rides on urban and rural roads. Answering that question will determine whether you need to purchase a mountain bike, hybrid, touring or road racing bike. The difference in the latter two will be determined by the amount of riding you plan to do. Although you may never race, a road racing bike will be the preferred choice if you plan to ride several times a week, and especially if you wish to progress by going farther and faster as time goes by.
2) Buy the right bike (Part 2): After determining the style of bike, the next thing you'll have to do is determine the correct bike size. To do this you'll have to measure your inseam, which will determine the correct size as measured by the frame size.
3) Get a proper fit: Once you've purchased your bike it's extremely important to have it properly fitted to your own body measurements. Having a seat set too high or too low is a recipe for knee problems down the road. An incorrect fore-aft seat position could cause back problems. If you purchase the bike from a reputable bike shop they should be able to help you through this process. You can also find out how to do this on your own by clicking here or here.
4) Before hitting the road: After purchasing your bike you're going to need some additional gear before hitting the trail or road. You'll definitely want to purchase a CPSC certified bike helmet, seat fanny pack, water bottle cage(s), an extra inter tube and a flat tire repair kit. Although frame air pumps were quite common several years ago, I much prefer CO2 cartridges for re-filling a fixed flat tire. The cartridges easily fit into your seat fanny pack, and are very easy to use. Other items to strongly consider include: bike gloves, jerseys, cycling shorts, a floor air pump for home (tire tubes tend to lose significant air pressure after a week or two), chain oil (to keep your chain spinning efficiently), and a bike computer. Although it may not be apparent to a beginner, most of these items serve a variety of important functions.
If you do plan to ride frequently I would also strongly recommend purchasing clipless pedals and cycling shoes. Clipless pedals allow you to apply pressure throughout the entire pedal motion, while standard pedals only allow you to apply pressure during the downward stroke. Because of this, clipless pedals are far more efficient and make cycling a lot easier as they allow you to spin, rather than push your pedals.
5) Choose safe routes: Once your entire "kit" is ready to go, it's time to hit the road or trail. As a beginner you'll definitely want to ride on bike friendly roads and trails. Fortunately, with the internet, there are many resources for finding safe routes. It's possible your own city or town has published a map on their website showing all the safe routes in town. Google Maps has a function for finding bike-friendly routes. TrailLink and MapMyRide are also great resources. You can also try checking with your local bike club or bike shop for recommendations as well.
6) Hold your head up: To quote the old Argent song, "hold your head up!" While riding it's extremely important to know everything that's going on around you. Don't stare down at your pedals, or your computer. Look ahead to know where traffic is, or where any obstacles might be on the road or trail, such as broken glass, a pothole, gravel (be especially cautious while turning corners), or a tree branch, etc.. Look from side to side to make sure a dog, wild animal, child, or even lawn professionals (for some reason these folks regularly step out onto the road without looking) don't decide to walk in front of your path.
7) Your butt will hurt: Unfortunately your butt will definitely hurt during the first couple of rides. Actually, the same holds true for experienced cyclists after we emerge from a long winter's rest. The best thing to do is to limit your rides to less than 30 minutes on the first couple of rides. You'll also be better off by not riding on consecutive days for the first week or so. Padded cycling shorts will be of help as well. Although you'll feel a little discomfort the first couple times out, don't worry, in no time you'll get used to it and will find that sitting on a bicycle seat is no longer a problem.
8) Never assume a driver can see you: With our epidemic of distracted and inconsiderate motorists texting and yapping on cell phones, you should never assume a driver can see you. Just because you made it to a stop sign first, make sure you make eye contact with a driver before crossing an intersection. Also, just because you don't have to stop at another intersection, don't assume the driver approaching from a perpendicular street is going to stop. Over the years I've seen numerous drivers ignore stop signs right in front of me. Luckily I slowed beforehand to make sure they were going to stop first. Also, don't assume someone crossing your path while turning into or out of a driveway or parking lot can see you. Finally, watch for parked cars. It's possible that someone is in that car and about to open up their door - you don't want to test your ability to strip a door from a car.
9) Hold that line!: As an example, let's say you're riding one foot from the side of the road. You should try to maintain that distance (called "holding your line") as much as possible. Not only will you be more predictable for drivers approaching from behind, but you never know when another cyclist might approach you from behind without saying anything. If you cross paths (touching tires), it's likely one or both of you will go down. If riding in a group this rule is even more important. Obviously there will always be obstacles along the course. In those situations be sure to look quickly behind you to make sure it's alright to alter your line. Also, as a reminder, cyclists are considered to be a vehicle in the eyes of the law, so you must obey all traffic laws.
10) Let the terrain dictate your gears: To be an efficient cyclist you need to maintain a fairly constant pedal speed, as measured in RPMs. This is the number of "Revolutions Per Minute", or complete pedal strokes in a one minute time period. The most efficient pedal speed is in the 90-100 RPM range. Take the time to count your RPMs to get a feel for what 90-100 RPMs feels like. Over time this pedal speed will be instinctive and will come naturally to you. If you're only doing 70 or 80 RPMs it's likely you're in too large of a gear. Over time it will feel like your simply grinding out the miles. Maintaining 90-100 RPMs is the most optimal range, and will allow your legs to feel fresher for longer periods of time, thus allowing you to ride longer and faster. As the terrain changes adjust your gears to maintain that optimal range. Obviously, on steep hills, it will be impossible to maintain that pedal speed. Simply shift down to your lowest gear and try to spin as much as possible.
11) Avoid the death grip: Many new cyclists will hold onto their handlebars as if they were about to fall off a cliff. This is a big mistake, as this only causes tension and will result in a stiff upper back. It's best to relax your upper body and let your legs do all the work. Learn to have a light touch while holding onto the handlebars. Use different parts of the handlebars as well, such as the break hoods, the outside and inside portion of the tops, as well as the drops. Switching around on different areas of the handlebar will allow you to use and rest different muscles in your arms, shoulders and back, thus helping to prevent them from stiffening up. Here's pretty good video that shows how and when to use the different positions.
In my view these are the top things you need to know to get started in the sport of cycling. There are many other tips and techniques to make cycling safe and fun, but are beyond the scope of this article. Reading online articles, books and magazines will be of help, but experience will be your best guide. I also recommend taking beginner type rides with your local bike club. More often that not you'll be able to find someone who is more than willing to teach you the ropes.

To help newbies dive into the sport, the following are my top 11 tips for beginner cyclists:
1) Buy the right bike (Part 1): Before dipping your toes in, the first thing you need to consider is what kind of bike to purchase. The answer to that question will be determined by what kind riding you plan to do: off-road trail riding, dirt/gravel roads, cruising around the neighborhood, or venturing out to do one or two-hour rides on urban and rural roads. Answering that question will determine whether you need to purchase a mountain bike, hybrid, touring or road racing bike. The difference in the latter two will be determined by the amount of riding you plan to do. Although you may never race, a road racing bike will be the preferred choice if you plan to ride several times a week, and especially if you wish to progress by going farther and faster as time goes by.
2) Buy the right bike (Part 2): After determining the style of bike, the next thing you'll have to do is determine the correct bike size. To do this you'll have to measure your inseam, which will determine the correct size as measured by the frame size.
3) Get a proper fit: Once you've purchased your bike it's extremely important to have it properly fitted to your own body measurements. Having a seat set too high or too low is a recipe for knee problems down the road. An incorrect fore-aft seat position could cause back problems. If you purchase the bike from a reputable bike shop they should be able to help you through this process. You can also find out how to do this on your own by clicking here or here.
If you do plan to ride frequently I would also strongly recommend purchasing clipless pedals and cycling shoes. Clipless pedals allow you to apply pressure throughout the entire pedal motion, while standard pedals only allow you to apply pressure during the downward stroke. Because of this, clipless pedals are far more efficient and make cycling a lot easier as they allow you to spin, rather than push your pedals.
5) Choose safe routes: Once your entire "kit" is ready to go, it's time to hit the road or trail. As a beginner you'll definitely want to ride on bike friendly roads and trails. Fortunately, with the internet, there are many resources for finding safe routes. It's possible your own city or town has published a map on their website showing all the safe routes in town. Google Maps has a function for finding bike-friendly routes. TrailLink and MapMyRide are also great resources. You can also try checking with your local bike club or bike shop for recommendations as well.
6) Hold your head up: To quote the old Argent song, "hold your head up!" While riding it's extremely important to know everything that's going on around you. Don't stare down at your pedals, or your computer. Look ahead to know where traffic is, or where any obstacles might be on the road or trail, such as broken glass, a pothole, gravel (be especially cautious while turning corners), or a tree branch, etc.. Look from side to side to make sure a dog, wild animal, child, or even lawn professionals (for some reason these folks regularly step out onto the road without looking) don't decide to walk in front of your path.
7) Your butt will hurt: Unfortunately your butt will definitely hurt during the first couple of rides. Actually, the same holds true for experienced cyclists after we emerge from a long winter's rest. The best thing to do is to limit your rides to less than 30 minutes on the first couple of rides. You'll also be better off by not riding on consecutive days for the first week or so. Padded cycling shorts will be of help as well. Although you'll feel a little discomfort the first couple times out, don't worry, in no time you'll get used to it and will find that sitting on a bicycle seat is no longer a problem.
8) Never assume a driver can see you: With our epidemic of distracted and inconsiderate motorists texting and yapping on cell phones, you should never assume a driver can see you. Just because you made it to a stop sign first, make sure you make eye contact with a driver before crossing an intersection. Also, just because you don't have to stop at another intersection, don't assume the driver approaching from a perpendicular street is going to stop. Over the years I've seen numerous drivers ignore stop signs right in front of me. Luckily I slowed beforehand to make sure they were going to stop first. Also, don't assume someone crossing your path while turning into or out of a driveway or parking lot can see you. Finally, watch for parked cars. It's possible that someone is in that car and about to open up their door - you don't want to test your ability to strip a door from a car.
9) Hold that line!: As an example, let's say you're riding one foot from the side of the road. You should try to maintain that distance (called "holding your line") as much as possible. Not only will you be more predictable for drivers approaching from behind, but you never know when another cyclist might approach you from behind without saying anything. If you cross paths (touching tires), it's likely one or both of you will go down. If riding in a group this rule is even more important. Obviously there will always be obstacles along the course. In those situations be sure to look quickly behind you to make sure it's alright to alter your line. Also, as a reminder, cyclists are considered to be a vehicle in the eyes of the law, so you must obey all traffic laws.
10) Let the terrain dictate your gears: To be an efficient cyclist you need to maintain a fairly constant pedal speed, as measured in RPMs. This is the number of "Revolutions Per Minute", or complete pedal strokes in a one minute time period. The most efficient pedal speed is in the 90-100 RPM range. Take the time to count your RPMs to get a feel for what 90-100 RPMs feels like. Over time this pedal speed will be instinctive and will come naturally to you. If you're only doing 70 or 80 RPMs it's likely you're in too large of a gear. Over time it will feel like your simply grinding out the miles. Maintaining 90-100 RPMs is the most optimal range, and will allow your legs to feel fresher for longer periods of time, thus allowing you to ride longer and faster. As the terrain changes adjust your gears to maintain that optimal range. Obviously, on steep hills, it will be impossible to maintain that pedal speed. Simply shift down to your lowest gear and try to spin as much as possible.
11) Avoid the death grip: Many new cyclists will hold onto their handlebars as if they were about to fall off a cliff. This is a big mistake, as this only causes tension and will result in a stiff upper back. It's best to relax your upper body and let your legs do all the work. Learn to have a light touch while holding onto the handlebars. Use different parts of the handlebars as well, such as the break hoods, the outside and inside portion of the tops, as well as the drops.

GÉOPOLITIQUE : Course aux armements au Moyen-Orient !
Salut à tous,
Du site le Huffington Post Québec :
¨ Tout comme les ventes de pétrole, les ventes d'armes jouent un rôle prépondérant dans les orientations politiques des grandes puissances au Moyen-Orient. Ces ventes influencent grandement leur position respective dans cette région du monde et expliquent certains de leurs réalignements de l'heure.
Au temps de la Guerre froide !
De 1965 à 1989, les achats d'armes se faisaient dans le contexte qualifié de Guerre froide. Les États-Unis voulaient protéger les pays pétroliers et l'URSS cherchait à cerner et à déstabiliser ces derniers. Les principaux acheteurs d'armes furent l'Irak (93 G$), l'Arabie saoudite (62 G$), l'Iran (51 G$), la Syrie (46 G$).
Le marché iranien !
À la suite du démantèlement de l'Union soviétique, l'alignement des pays de l'Europe de l'Est par rapport à l'Union européenne et à l'OTAN a grandement frustré la Russie. En outre, aux yeux des Russes, l'intervention de l'OTAN en Libye leur a fait perdre un marché lucratif de plusieurs milliards de dollars. C'est la raison pour laquelle la Russie s'accroche aux ventes d'armes à l'Iran, qui finance également les achats d'armes de la Syrie. Depuis 1995, 70% des armements iraniens proviennent de la Russie (la livraison du système de défense anti-aérien S-300 est à l'ordre du jour). Le maintien du statu quo en Syrie garantit à la Russie le monopole des marchés syriens et iraniens.
Le désengagement américain !
Les États-Unis sont déçus du comportement de la Turquie à son égard*, particulièrement en ce qui a trait à la guerre contre l'État islamique, la Turquie ne permettant pas l'utilisation des bases américaines sur son territoire. Le bilan de l'intervention américaine en Irak et en Afghanistan, coûteuse à bien des égards, est désastreux. Par ailleurs, des pays pétroliers financent des mouvements islamiques radicaux antiaméricains.
Le marché croissant des ventes d'armes !
À elle, seule, l'Arabie saoudite a dépensé 500 G$ pour son budget de défense au cours des vingt dernières années. Les ventes d'armes globales pour l'année 2014 se sont chiffrées à 64,4 G$, soit une augmentation de 15% par rapport à l'année précédente. Les États-Unis viennent en tête des exportateurs d'armes avec 23,7 G$, suivis par la Russie (15 G$). L'Arabie saoudite a été en tête des importateurs d'armes (6,5 G$), suivie par l'Inde (5,8 G$), la Chine et les Émirats arabes unis. Les ventes d'armes durant l'année 2014 mettent en évidence l'augmentation substantielle des achats d'armes des pays pétroliers, achats que l'on peut attribuer à la crainte du désintérêt relatif des États-Unis de cette région du monde, de même qu'à celle de l'expansion iranienne¨...

Programming Note: Friends Across the Mountains Telethon is Thursday Night
This Thursday, August 20th, is the 21st annual Friends Across the Mountains Telethon. The event will be broadcast on WBIR-TV Channel 10 in Knoxville, TN and WLOS-TV Channel 13 in Asheville, NC from 7:00 PM - 8:00 PM.
The broadcast will highlight projects and programs that Friends of the Smokies has funded over the years. It's a fun event that raises awareness of both the Park's needs (as the only major national park without an entrance fee), and the ways that Friends of the Smokies helps to fulfill some of those needs every year. The telethon raises roughly $200,000 each year, and has raised more than $3 million dollars over the last 20 years.
Volunteers will be on hand to help answer phones and keep running totals of the money raised throughout the evening.
If you wish, you can make a donation right now by clicking here.

Celebrate the 99th Birthday of the National Park Service: All National Parks Will Offer Free Admission on August 25
The National Park Service is turning 99 years old on August 25, 2015, and everyone is getting a present, free admission! Visit a park in your neighborhood or plan a trip to one of the 408 National Park Service sites across the country to join the party! To inspire visitors, the National Park Service and the National Park Foundation, the official charity of America’s national parks, have created a birthday list of 99 Ways to Find Your Park.
“The National Park Service’s 99th birthday is an opportunity to reflect on and celebrate the role of national parks in the American story,” said National Park Service Director Jonathan B. Jarvis. “And it’s also a time to look ahead to our centennial year, and the next 100 years. These national treasures belong to all of us, and we want everyone – especially the next generation of park visitors, supporters and advocates – to discover and connect with their national parks.”
In preparation for the centennial celebration next year, the National Park Service and the National Park Foundation are partnering to help audiences nationwide Find Your Park. To encourage visitors to discover everything a park experience can be, the list of 99 Ways to Find Your Park includes a wide range of activities: from urban hikes and taking a sunrise selfie, to earning a Junior Ranger Badge and writing poetry. Visitors are encouraged to share their park experiences with friends and family by using #FindYourPark on social media.
On August 25, 1916, President Woodrow Wilson signed legislation to create the National Park Service, which preserves and protects 408 sites throughout the country. Each one, whether it’s a national park, a historic site or a national seashore, was established by a president or Congress to protect, preserve and share its national significance for future generations. Some parks commemorate notable people and achievements; others conserve magnificent landscapes and natural wonders; and all provide a place to have fun and learn.
The National Park Service waived all of its entrance fees on nine days in 2015. The remaining entrance fee free days are August 25 for the National Park Service’s birthday, September 26 for National Public Lands Day, and November 11 in honor of Veterans Day. The entrance fee waiver does not cover amenity or user fees for activities such as camping, boat launches, transportation, or special tours.

Update on Wildfires in Pisgah National Forest
The Southern Area Gold Team and the North Carolina Forest Service are now in unified command, managing both the Bald Knob and Wolf Creek Fires. Yesterday was the first day of full management of the incidents under this command. Both the Bald Knob Fire (confirmed lightning start on July 17th) and Wolf Creek Fire (likely lightning start on July 31st) started on the Pisgah National Forest. The cause of the fire was likely lightning, although the ignition source remains unconfirmed.
The team will continue to use a “confine and contain” strategy to manage both fires for multiple objectives. Limited access, rough terrain and heavy fuel loading make direct access unviable for firefighters on the Bald Knob Fire. Firefighter crews will work to construct and enforce fire lines using dozers and hand crews where they have access.
The Bald Knob fire is now estimated to be 1019 acres, and is 0% contained. 163 firefighters are currently fighting this blaze.
The Wolf Creek fire is 305 acres in size, and is 60% contained. 47 firefighters are working on this wildfire.
A temporary closure of a section of the Mountains to Sea Trail between the footbridge over the North Fork of the Catawba River and Dobson Knob Road (Forest Service Road 106) remains in place.

PSYCHOLOGIE : D'où vient la motivation ?
Salut à tous,
Du site Sciences Humaines :
¨ Un siècle de recherche en psychologie n’a pas suffi à percer l’énigme de la motivation. Elle a pourtant donné lieu à une centaine de théories ! Tour d’horizon des principaux modèles.
La notion de motivation a pris une place considérable dans nos sociétés. Le prof se demande comment motiver ses élèves, le manager ses équipes ; le marchand rêve de comprendre les motivations des consommateurs, le politique celle des électeurs. Son usage semble si courant qu’il semble difficile d’imaginer comment il a été possible de s’en passer.
Des instincts darwiniens aux pulsions freudiennes !
Historiquement, la notion d’instinct a été la première mobilisée pour comprendre ce que les psychologues appellent la direction du comportement. Il en subsiste encore toute une terminologie. Par exemple, on ne dira pas d’une mère qu’elle est motivée ou non pour s’occuper de son enfant mais qu’elle a ou non l’instinct maternel. William James est l’un de ces pionniers en psychologie qui, dès 1890, a proposé une liste composée d’une dizaine d’instincts pour expliquer les mystères du comportement humain : la peur, la colère, la sympathie, la curiosité, l’amour, etc.
Le béhaviorisme et les besoins physiologiques !
Ce courant de recherche, connu également sous le nom de comportementalisme, va dominer la psychologie jusqu’au milieu du 20e siècle. Pour lui, l’ensemble des comportements, qu’ils soient humains ou animaux, s’expliquent par des associations entre un stimulus (un signal) et un comportement (une réponse). Le premier à mettre en évidence cette association chez le chien a été le célèbre physiologiste Ivan Pavlov. Dans ses recherches, il a montré qu’il était possible dans un premier temps d’associer un son à de la nourriture pour que dans un deuxième temps, le son seul (le stimulus) soit en mesure de provoquer le comportement de salivation (la réponse) en l’absence de toute nourriture.
Les approches cognitives !
Depuis les années 1950, la psychologie a connu un autre changement paradigmatique, le cognitivisme, qui a introduit le concept de motivation non seulement dans le champ de la psychologie mais aussi plus largement dans le langage courant. L’un des premiers psychologues à utiliser ce terme, d’un point de vue scientifique, est Kurt Lewin qui a montré que la valeur d’une réussite dépend des attentes ou expectations des individus. Si l’individu réussit une performance facile, sa victoire a peu de valeur à ses yeux alors que s’il réussit à faire quelque chose où il s’attend à échouer, celle-ci en aura beaucoup.
Les théories de la motivation ont aussi pu mettre en évidence des mécanismes motivationnels liés à la prise de décision (comment on fait ses choix), ou encore aux stratégies qui conduisent les individus à adopter certains comportements.

Don't you hate it when...
Don't you just hate it when you have information to share but you are not permitted by contracts and commercial in confidence so share it? Our society is more and more being constrained by bureaucratic regulations set up by people who are career managers but have very little understanding of the real world. Little understanding that science and engineering knowledge benefit all people and that some perceived public image issue is more important than the wider good. This means that innovation can be stifled... at least in my personal opinion. The perceived public perception of scientific discoveries hinders the development of knowledge from Climate Change to Panadol!
By way of one a specific local example, I was helping an environmental centre have a ground water bore installed. The Department of Education which runs the environmental centre put absurd restrictions on access to the groundwater. One such limitation was that school children had to wear gloves when touching the groundwater in case it was contaminated. After running some tests it is apparent that the groundwater is actually better quality than the filtered tank water that they are currently drinking... but still the safety controls need to be in place! I'm happy to drink the water but the children must still wear gloves... go figure!
Another example is a cutting edge research project in the Woodburn-Evans area. The information gained from this research is very important for most coastal sand groundwater systems in eastern Australia. Alas, the words from a senior manager in a NSW government department are that no scientific information gained from the research is to be released to the public in the short term. What a shame. I understand that people are risk adverse today especially with regards to perceived public opinion but I don't think scientific knowledge should not be hidden away.
On a slightly different note I have received a copy of an in-press paper on Coal Seam Gas monitoring in the Northern Rivers area. I provided some minor assistance in the paper and so an author kindly showed me before it was published. It is expected to be released in a few weeks and is likely to be in the newspapers too. Keep an eye out for those three letters C, S & G.

The Appalachian Trail Conservancy Launches Video Series Aimed at Educating Hikers
Volunteers and staff at the Appalachian Trail Conservancy (ATC) have created a series of entertaining and informative videos that will teach visitors how to reduce their imprint on the Appalachian Trail (A.T.). The videos, titled “Don’t Be That Guy – Appalachian Trail - Leave No Trace,” were released this past weekend.
Filmed by professional videographer and former thru-hiker Tara Roberts with support from the U.S. Forest Service, the Leave No Trace Center for Outdoor Ethics, the ATC’s Tennessee License Plate Fund, and the ATC volunteers, the series illustrates the proper practices for hiking and camping that minimize impacts on the A.T.
“‘Leave No Trace’ is a great program that encourages everyone to minimize their impacts on the outdoors. These methods are needed on the Appalachian Trail, especially due to its popularity,” said Tom Banks, video producer and director. “There’s a lot of good information available from the Leave No Trace Center for Outdoor Ethics teaching the principles, and what these videos add is information that applies specifically to the Appalachian Trail. We illustrate the techniques in a direct, but entertaining, way.”
The series features a clip on each of the seven principles of Leave No Trace, which include plan ahead and prepare, travel and camp on durable surfaces, dispose of waste properly, leave what you find, minimize campfire impacts, respect wildlife, and be considerate of other visitors. Additional videos, to be released later in the month, will also include engaging elements like interviews with recent hikers and actors in the series as well as a lighthearted bloopers and outtakes reel. “We have to be vigilant. Our duty is to take care of the Appalachian Trail,” explained Sarah Jones Decker, a creative consultant, actor in the videos, and former A.T. thru-hiker. “As the Trail becomes more popular, we need to make sure that we are working diligently to spread the ‘leave no trace’ message."
The video series is one way the ATC is preparing for a surge in Trail use following the release of the film A Walk in the Woods, a comedy adventure starring Robert Redford and Nick Nolte as old friends who make the improbable decision to hike the 2,190-mile Trail. The film will be released September 2 by Broad Green Pictures. The ATC acted as a consulting organization during production and assisted with the film’s environmental messaging.
“Effort will be necessary to keep the Appalachian Trail in its natural state, especially given the increased attention that the Trail is receiving,” said Javier Folgar, the ATC’s director of Marketing and Communications. “Whether you are new to hiking or are an experienced 2,000-miler on the Appalachian Trail, everyone can benefit from watching these videos as a reminder of how to reduce impact.”
Here's an intro from the video series that explains "the Story Behind the Videos":
And here's a short clip of the "bloopers and outtakes" from the series:

Two Wildfires Burning in Pisgah National Forest
There are currently two wildfires burning in Pisgah National Forest.
The Bald Knob Fire, burning on land in McDowell County north of Marion, NC, increased to 190 acres over the weekend. The fire grew in size as weather patterns brought dry, less humid conditions to the area.
The Bald Knob Wildfire was reported on July 17th in a remote area near Dobson Knob, north of Lake James. Wetter weather kept the fire activity low for the first two weeks. With dry conditions over the weekend, fire activity and smoke have increased. Members of the public near Marion, NC and those traveling along State Highway 221 can expect to see and smell smoke, with heaviest smoke likely to occur in the afternoons when temperatures are high and humidity low.
With no significant rain forecasted over the next several days, officials expect the fire to continue to move north-west towards Dobson Knob. Firefighters are scouting for potential containment lines on the west side of the fire and improving existing lines on the south end.
The fire is moving naturally across the terrain in an area where damage from Southern Pine Beetle created high levels of fuels, leading to increased smoke from the fire. This area is adjacent to multiple prescribed burn areas that have recently been treated as part of the Grandfather Restoration Project which will limit the fire’s ability to spread rapidly. The Columbine Wildfire Module, a specialized unit experienced in managing fires for multiple objectives, is assisting with the “confine and contain” strategy currently being employed.
A temporary closure of a section of the Mountains to Sea Trail between the footbridge over the North Fork of the Catawba River and Dobson Knob Road (Forest Service Road 106) remains in place.
The cause of the fire was likely lightning though the ignition source remains unconfirmed.
Firefighters are also working to contain the Wolf Creek wildfire, which is also burning land in McDowell County. With dry conditions and low humidity, the fire grew Sunday afternoon and Monday morning and is now estimated at 75 acres and 30 percent contained. The Wolf Creek fire is located northwest of Old Fort, NC in steep terrain between Heartbreak Ridge and Jarrett Creek.
Firefighters completed containment lines on the south and west sides of the fire and are currently conducting burn-out operations. Crews are using low-intensity fire within the containment lines to reduce fuels in between the fire lines and the wildfire edge. Firefighters are also continuing to monitor the fire line along Jarrett Creek.
Members of the public can expect to see increased smoke today in the Old Fort area and along Interstate 40 and U.S. Highway 70. Travelers along I-40 between Ridgecrest and Marion, NC should use caution as smoke may settle along the highway this evening. The NCDOT has installed signs on I-40 westbound near Exit 81 and eastbound near Exit 66 warning travelers of the potential for smoke. With no significant rain forecasted over the next several days, officials expect the fire to continue to grow within containment lines.
Heartbreak Ridge Trail (208) and Star Gap Trail (209) remain closed to public use and will be in effect until further notice. Jarret Creek Road (FS4030) is also closed to public use. Forest Service officials are asking the public to avoid this area for their own safety and the safety of emergency response personnel on scene.
