Published in the journal Research in Developmental Disabilities, the study discovered that text with increased space between each letter provided a benefit to both groups of children. On average, the dyslexia group showed a 13% increase in reading speed, while the comparison group of non-dyslexic children showed a 5% increase in reading speed.
Participants read four texts with either standard or extra-large letter spacing, both with and without a coloured overlay. The children were instructed to read the text out loud while being recorded. The recording was used to measure the number of errors they made -- specifically missed words, added words, wrong words, and pronunciation -- as well as the participants' reading time.
In addition to improved reading speed for both children with dyslexia and the non-dyslexic group, the larger letter spacing also resulted in a significant reduction in the number of words being missed by the children with dyslexia. However, the study found that coloured overlays had no significant impact on reading speed or the reduction of errors for either group of children.
Dr Stagg, Senior Lecturer in Psychology at Anglia Ruskin University (ARU), said: "We found that extra-large letter spacing increases the reading speed of children both with and without dyslexia, and significantly reduces the number of words that dyslexic children skip when reading.
"While we found that colour overlays provided little benefit, we suggest that children should be encouraged to use overlays if they find these help their reading. Colour overlays may not increase reading speeds, but they may extend reading stamina. Previous research suggests their benefits may not become apparent if reading time is less than 10 minutes and the short reading duration of the tests in our study may have put colour overlays at a disadvantage."
It can seem like a lot on top of the cost of your Pass, but trains that ask for mandatory reservations normally save you a lot of time, and have plenty of extra features like wifi and power sockets, so you can sit back and relax while you speed to your next destination.
If you're traveling on a budget, remember that most slower national and regional trains don't require seat reservations, so if you're willing to take the scenic route you can often avoid the extra cost.
The Speed item resembles a winged boot. Upon activation, it increases nearly every action of the hero using it. Movement, shot speed, melee attack speed, all increase in tempo; it also stacks with every other item. As such, it's valuable to have when fighting tougher monsters such as Golems and Gargoyles and various bosses. They are very useful for slower heroes when collecting Coins in Treasure Rooms, to ensure that all the coins are found before time runs out.
Cutting through the ocean like jets through the sky, giant bluefin tuna are built for performance, endurance, and speed. Just as the fastest planes have carefully positioned wings and tail flaps to ensure precision maneuverability and fuel economy, bluefin tuna need the utmost control over their propulsive and stabilizing structures as they speed through the ocean.
The footage allowed the researchers to establish how the tuna changed the area and shape of these fins in order to execute different maneuvers. Paired with computer model simulations, the team also showed how fluid flowed across the tuna, impacting the forces generated by the fin at different swimming speeds.
Cost/Gallon: When driving 50 mph, price per gallon is assumed to be the same as the pump price. At higher speeds, the estimated price per gallon is increased based on the additional fuel you use by driving faster. The price of fuel doesn't actually go up, but this is a useful way to put the cost of driving faster in context.
Save Money: This graph shows how much money you can save by slowing down. Cost per gallon and cost per 100 miles show the difference in cost at your typical highway speed and the cost at the reduced speed.
We estimate vehicle MPG at steady-state cruising speeds based on the vehicle's EPA "highway" fuel economy rating. These estimates are typically higher than both the EPA highway MPG ratings and the MPG consumers experience in on-road highway driving. Therefore, our cost and savings estimates should be conservative.
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by about 1%.6 The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
Skateboarders in half-pipes and bowls have a need for speed. The faster they go, the higher they can fly up over the lip. Achieving greater heights is not only impressive on its own, it's necessary for pulling off acrobatic tricks like Caballerials and McTwists.
On flat ground, the conventional method for gaining speed is to push off with one foot. But the curved surfaces of half-pipes and bowls present a much more elegant option for the speed-hungry skater. It's called pumping.
To pump, a skater first drops down into a crouch while traversing the more-or-less flat bottom of the U-shaped pipe or bowl. Then, as she enters the sloped part of the ramp or bowl, called the transition, she straightens her legs and rises up. By raising her center of mass just at the beginning of the arc, the skater gains energy and thereby increases her speed.
From a physics point of view, the extra speed that comes from both kinds of pumping is a result of the equivalence of work and energy. As you move into the bottom the arc, centripetal force makes it harder than normal for you raise yourself. The net work you perform in lifting yourself is equivalent to a net energy gain. This energy gain translates into extra speed and greater height at the top of the swing or ramp.
No person shall drive a vehicle on a highway at a speed greater than is reasonable and prudent under the conditions. Every driver is responsible for becoming and remaining aware of the actual and potential hazards then existing on the highway and must use due care in operating a vehicle. In every event speed shall be so restricted as may be necessary to avoid colliding with any person, vehicle or other conveyance on or entering the highway in compliance with legal requirements and the duty of all persons to use due care.
The driver's license of a person who violates any speed limit established in this section, by driving in excess of 100 miles per hour, is revoked for six months under section 171.17, or for a longer minimum period of time applicable under section 169A.53, 169A.54, or 171.174.
(a) The driver of any vehicle shall, consistent with the requirements, drive at an appropriate reduced speed when approaching or passing an authorized emergency vehicle stopped with emergency lights flashing on any street or highway, when approaching and crossing an intersection or railway grade crossing, when approaching and going around a curve, when approaching a hill crest, when traveling upon any narrow or winding roadway, and when special hazards exist with respect to pedestrians or other traffic or by reason of weather or highway conditions.
(b) A person who fails to reduce speed appropriately when approaching or passing an authorized emergency vehicle stopped with emergency lights flashing on a street or highway shall be assessed an additional surcharge equal to the amount of the fine imposed for the speed violation, but not less than $25.
On determining upon the basis of an engineering and traffic investigation that any speed set forth in this section is greater or less than is reasonable or safe under the conditions found to exist on any trunk highway or upon any part thereof, the commissioner may erect appropriate signs designating a reasonable and safe speed limit thereat, which speed limit shall be effective when such signs are erected. Any speeds in excess of such limits shall be prima facie evidence that the speed is not reasonable or prudent and that it is unlawful; except that any speed limit within any municipality shall be a maximum limit and any speed in excess thereof shall be unlawful. On determining upon that basis that a part of the trunk highway system outside a municipality should be a zone of maximum speed limit, the commissioner may establish that part as such a zone by erecting appropriate signs showing the beginning and end of the zone, designating a reasonable and safe speed therefor, which may be different than the speed set forth in this section, and that it is a zone of maximum speed limit. The speed so designated by the commissioner within any such zone shall be a maximum speed limit, and speed in excess of such limit shall be unlawful. The commissioner may in the same manner from time to time alter the boundary of such a zone and the speed limit therein or eliminate such zone.
When local authorities believe that the existing speed limit upon any street or highway, or part thereof, within their respective jurisdictions and not a part of the trunk highway system is greater or less than is reasonable or safe under existing conditions, they may request the commissioner to authorize, upon the basis of an engineering and traffic investigation, the erection of appropriate signs designating what speed is reasonable and safe, and the commissioner may authorize the erection of appropriate signs designating a reasonable and safe speed limit thereat, which speed limit shall be effective when such signs are erected. Any speeds in excess of these speed limits shall be prima facie evidence that the speed is not reasonable or prudent and that it is unlawful; except that any speed limit within any municipality shall be a maximum limit and any speed in excess thereof shall be unlawful. Alteration of speed limits on streets and highways shall be made only upon authority of the commissioner except as provided by law.
