The Secret Service — known for protecting the president — is now using their expertise to protect schools in the wake of a spate of deadly mass shootings.

The new guidelines on enhancing school safety are based on research from the U. Lina Alathari, the author of the operational guide, told ABC News that although guns were used the majority of the time in the crimes studied, the report also includes attacks carried out using a "lethal weapon," such as a knife, gun or explosives. After the shooting at Columbine High School in Colorado, the Secret Service approached the Department of Education and offered to use the same methods they use to study assassins to study school shooters.

The purpose of the report was to show a "blueprint" for how schools can establish threat assessment programs in their schools so that they are identifying students who may be expressing distress or engaging in concerning behavior, she said. In the operational guide, the Secret Service says there is no profile for a student attacker.

It could be male or female. It could be a good student or someone who struggles academically. It could be someone who is a loner, or well liked. The Secret Service also says that schools should establish a threat assessment team, which they say is "the first step" in developing a prevention plan.

That team, which can be for just one school or an entire school district, should be diverse. It also recommends that the team meets on a regular basis and have a clear leader.

According to Alathari, having a school resource officer on the team is helpful in identifying potential risk and they are often the first ones to respond on the scene. And in most cases, those officers have relationships with the students. They bond with them, sometimes they serve as coaches on teams, sometimes they co-teach classes; a lot of students feel comfortable having that presence in their schools.

For example, in Colorado during the school year, most incidents submitted on the Colorado Safe2Tell program, a tip line dealt with "suicide, bullying, drugs, cutting self-harm , and depression. Creating a central reporting mechanism is also important to the process of stopping student attackers, according to the report. Many of the applications schools use resemble nationwide criminal reporting apps. The team should also put in place procedures — which includes who conducts interviews with troubled students, classmates and teachers.

They should also have an evaluation process which determines which behaviors are unacceptable and warrant immediate intervention — ranging from threatening others, violence, bringing a weapon to school, bullying. If there is an immediate threat, however, like a threat to harm others or themselves, it is important to report it to someone as soon as possible.

The operational guide also says to be alert to whether a student has readily available access to weapons. For example, authorities said that the school shooter who killed 10 and injured 13 in Santa Fe, Texas used his father's weapon to carry out the attack. In fact, Alathari said that the majority of the weapons in many of the school shootings were acquired from the home.

Trump described the letter as a "very nice note" and said, "Great progress being made! That's when Secretary of State Mike Pompeo visited Pyongyang and seemingly made little progress in fleshing out details of North Korea's commitment for "complete denuclearization.

US delegation met with North Korea to discuss next steps in denuclearization Kim also agreed then to repatriate remains of U. A planned meeting Thursday between North Korean and U. It wasn't immediately clear what prompted the postponement. South Korea's Yonhap news agency, citing unnamed sources, said the North requested talks at a higher level. The talks Sunday are expected to involve officials from the Pentagon and the U.

Command, which commanded U. Pompeo told reporters after his visit to North Korea last week that the meeting in the truce village Panmunjom was set for Thursday but "could move by one day or two. Pompeo gave a rosier readout.

He reported that the two sides had substantive discussions on next steps toward denuclearization. During an official visit to Britain, Trump posted images of the Korean- language letter from Kim and its English translation.

Kim expresses "invariable trust and confidence" in the president and wishes that "epochal progress" in promoting relations will "bring our next meeting forward.

Recent reports suggest that the North has continued to expand infrastructure at nuclear and missile sites and that U. The U. Trump himself has remained upbeat about the outcome of the first summit between the leaders of the U. Earlier Thursday, after attending the NATO summit in Brussels, he told reporters that there were clear signs of progress with North Korea, most notably that no missile and nuclear tests have occurred for almost nine months.

Lederer at the United Nations contributed to this report. At least seven people associated with longtime Trump friend Roger Stone have been contacted by special counsel Robert Mueller, according to interviews with witnesses and others who say they've been contacted.

Substitute the total cost function into the demand function and solve for V. Add 25 cents to the original cost function. Add 50 cents to the original cost function. Determine the new volume of vehicles wanting to cross this bridge. Substitute the new cost function into the demand function and solve for V. Assume toll rate at T. Since the revenue generated is the toll rate, T, time the volume, V, first solve for V with the new cost function.

It is desired to increase the toll to a point where revenue will be maximized. Write the expression for travel demand on the bridge. Substitute the above expressions into the revenue function and differentiate with respect to x, setting the derivative equal to zero.

Now, substitute the new toll, x, into the demand function developed in part a. Determine the total revenue with the new toll. First, solve for the revenue to be generated by the new toll. For practical purposes and traveler convenience, round the toll increase to 75 cents.

Next, determine the resulting volume after the new toll increase. Simply substitute the new toll into the demand function above. The manufacturer uses a utility formula that rates each mode.

Discuss at least two. Let Utruck be the dis utility function for the trucks and Urail the dis utility function for the railroad. Reliability: Does the mode consistently operate on schedule? Convenience: Which mode can deliver the freight to a serviceable location? Security: Which mode reduces the risk of pilfering.

Rideability: Which mode provides the best ride for the product? In other words, which mode is less likely to cause damage to the product while in transit? Three possibilities exist: air, rail, or auto.

Determine the total cost initial cost plus time cost for each mode. Other factors to consider, other than costs, when selecting a mode to travel might include the following: personal comfort the modes have to offer, whether additional connections need to be made to reach the final destination, the level of stress that can be anticipated by traveling by that mode, or whether the reason for travel is for business or pleasure.

The long-term viability of the fuel tax is affected by crude oil shortages, improved automobile efficiency, use of alternative energy sources, and shifts to public transportation.

Additionally, the availability of revenue is reduced by diversion of fuel taxes to support transit, ethanol, and government general funds. Several financing concepts, including road use metering, electronic toll collection, and value pricing, may help to offset ineffectiveness in the fuel tax as vehicles become more fuel-efficient.

Road use metering involves charging highway users according to consumption vehicle-miles traveled , similar to many utilities. Electronic tolling is a related concept that can be applied on toll roads. Value pricing involves payment for values of service rendered as a function of demand. The secretary is also the chairperson of the Commonwealth Transportation Board, a 16 member policy board that functions as a board of directors to i oversee the construction of highways and make regulations governing the use of state highways, ii ensure compliance with transportation-related federal laws, iii collect transportation statistics, iv regulate the location of outdoor advertising, v oversee the administration of the Transportation Trust Fund, and vi generally oversee the operation of the Virginia Department of Transportation VDOT.

This includes the daily maintenance and repair, design and engineering of future road projects, and the long range planning based on future demand projections. This organization has its central headquarters located in Richmond, Virginia, and nine other District offices strategically located in other areas of the state. These District offices employ individuals to maintain the roads and the right-of-way year round, which includes the mowing of grass in the summer and plowing snow in the winter.

In addition to the roadways, VDOT is also responsible for all of the roadway signs, signals, and street lighting. The activities focus around the phase of transportation project development: planning, design, construction, operations, and maintenance.

Organizational structure supports these responsibilities. Department of Transportation website and identify the name and location of highways in your state that are included as part of the National Highway System.

According to data, Virginia has approximately 3, miles of the NHS. In Urban areas, there are 1, miles of highways: miles of Interstates, miles of other Freeways and Expressways, miles of other Principal Arterials, 36 miles of Minor Arterials, 6 miles of Major Collectors, and 2 miles of Local roads. This includes Interstates 64, 77, 81, 85, 95, and Principal Arterials and strategic connectors, such as U.

United Airlines: Provides passenger airline service to several cities outside the state. Norfolk Southern Corporation: Provides freight rail service throughout the eastern U.

The results of contractor-performed tests on in-place properties of hot-mix asphalt are increasingly used in the acceptance decision in many states. Results of tests performed by contractors and state departments of transportation DOTs in North Carolina, Florida, and Kansas consistently indicate that differences between contractors and state DOT test results for hot-mix asphalt concrete mat density are statistically significant.

Furthermore, these comparisons consistently indicate less variable and more favorable contractor test results, relative to specification limits, that give more favorable acceptance outcomes. Details of quality assurance processes sampling and testing frequencies, test methods, verification procedures, and acceptance procedures appear to have little if any effect on these comparisons.

These findings provide information for state DOTs to consider in structuring their quality assurance programs, specifically the role of contractorperformed tests in acceptance decisions.
