However, New Deal economics felt the greatest impact of the Cold War. By the 's, New Deal reforms were often associated with the left. Its advocates were attacked for promoting programs close to the realm of socialism. The presidencies of Truman and Eisenhower kept away from the Rooseveltian ideals of social and economic reforms. For veterans the economic future brightened as the government spent countless resources through the GI Bill, VA and FHA loans to help them buy new homes or receive an education.

Social reforms in the fields of civil rights, labor unions, working conditions, and women concerns were minimum and often ignored. In human behavior, consensus to anti-communist ideals became the norm for everyone, especially government employees. Firm anti-communist demeanor was expected from everyone, particularly those in government. Campaigns to rid government of so-called "reds" became commonplace.

In such a fervent era of anti-communism, the junior senator for Wisconsin, Joseph McCarthy, employed this hysteria to prosecute countless government officials. To promote liberal ideas, civil rights advancements or possible cooperation with communist states was enough to mark a person for persecution. Changes in the "conformity" of America however, did not occur until the end of the 's, coming slowly at first.

Radulovich had been asked to resign because his father and sister were once accused of reading "subversive newspapers. Movies became a vehicle to exhibit the discontent against the system with films by James Dean and Marlon Brandon among a few. Literature flourished with themes of individualism versus the system. With poets like Robert Lowell, critics like Dwight McDonald, movies like "Rebel Without a Cause" and "The Wild Ones", rock-and-roll music, and college student unions, "conformity" in the 's was all but secured.

These critics of "conformity" championed individualism and the younger generation's anxiety over nuclear war. Another area of criticism was the economy. Even though poverty had declined, between one-fifth to one-fourth of the nation could not survive on the income earned. The longest conflict of the twentieth century, the Cold War affected everything, from political ideology, foreign and domestic policy, to the presidency and the personal lives of Americans. With the collapse of the Iron curtain in Eastern Europe, the unification of Germany, the fragmentation and subsequent dissolution of the Soviet Union have all but eliminated the Cold War.

International cooperation during the first Gulf War demonstrated that even before the end of the Soviet Union, the rhetoric of the past no longer had any place in American foreign or domestic policy. Notes: 1. William H. The Unfinished Journey. On This Page. Drivers and passengers can: Use a seat belt in every seat, on every trip, no matter how short. Make sure children are always properly buckled in the back seat in a car seat, booster seat, or seat belt, whichever is appropriate for their age, height, and weight. Choose not to drive while impaired by alcohol or drugs, and help others do the same. Obey speed limits. Drive without distractions such as using a cell phone or texting.

Motor vehicle crash deaths in the US are still too high. Major risk factors for crash deaths in the US. Not using seat belts, car seats, and booster seats contributed to over 9, crash deaths. Drunk driving contributed to more than 10, crash deaths. Speeding contributed to more than 9, crash deaths. Seat belts saved over 12, lives in the US in , yet: The US had lower-than-average front and back seat belt use compared with other high-income countries. Some proven measures of best performing high-income countries. Some of the best performing countries: Have policies in line with best practices, including those that address: Primary enforcement of seat belt laws that cover everyone in every seat. Police officers can stop a vehicle and write a ticket for anyone not buckled up.

Requirements for car seats and booster seats for child passengers through at least age 8. Use advanced engineering and technology, such as: Ignition interlocks for all people convicted of drunk driving. This device keeps the vehicle from starting unless the driver has a BAC below a pre-set low limit. And, accordingly, bollard configurations are more predictable. Contrasted with drivers who are civil and compliant with society's norms are those who plan or carry out acts of property destruction, incite terrorism, or cause the deaths of civilian, industrial or military populations.

They are opportunistic, seeking for security system weaknesses and avoiding, where- and when-ever possible a facility's strengths. Employing crash- and attack-resistant bollards in the security design involves choices from a diverse pallet of styles. It is this versatility that influences the discussion. This Resource Page documents that the definitions of safety, security, and perimeter security design are fluid concepts; that changing threat, vulnerability, and risk assessments for any one situation can require implementation of different design scenarios.

For instance, when high profile domestic industries perceive themselves to be threatened in a manner similar to that in military environments, then security design codes and standards warrant shifts from a static to a more dynamic and fluid design. Because of their versatility bollards are important participants in changing security design. To show how bollards coordinate with other security designs e. To illustrate the emerging issue of how perimeter security design incorporates bollards randomly as a tactic to quell the impact of asymmetric terrorism.

While the metrics used for stopping effectiveness of active or passive bollards are the same see below , the differences between active and passive bollards are significant when they are compared on initial and life-cycle costs. Noticeably absent in the foregoing and next table is listing of K8 bollards. K8s, in recent times, and increasingly are being covered by K12 solutions. Illustrative manufacturer's costs in for manual and automatic retractable crash-certified active bollards vary by K-level and number of bollards per unit :. The installation time for all models in this table is three to five days for equipment and another three to four days for wiring. Following industry trends, the newest and now ascending innovation is the electric bollard design.

Being all-electric, it avoids the waste of hydraulics, doing away with waste pumps, fluid reservoirs, and hydraulic hoses. Models cover the entire crash-resistance range, operating speed matches that of hydraulics, and installation and maintenance cost are reported to be lower. Specific manufacturer information is available at:. Retractable bollards, again compared to inactive bollards, come with a price that further exceeds front-end equipment and installation costs and adds significantly to total life-cycle costing. Additional or continuing costs include:.

The potential for injury to barrier operators requires warning signs, lights, bells, and bright colors to make the presence of the barrier known, and these must be maintained. Additional costs are back-up power, emergency cut-off switches, and installation of safety options. Barrier location invites sabotage when they are left unattended in remote areas.

Additional costs are for anti-tamper switches, tamper-proof screws, and roaming security guards. When properly maintained an ongoing cost , barrier failure rate is less than three percent. Local staff, however, requires training by the manufacturer for everyday- type operations independent of contracted maintenance. Maintenance contracts inclusive of labor and parts are an indispensible cost reducing down time and system vulnerability to penetration.

Environmental Challenges. Hinges, hydraulics, or surfaces with critical tolerances to weather conditions require added attention by local operators. Architects, engineers, security designers, and end users need to understand the changing terminology associated with selecting appropriate barriers to protect their vital assets. Crash-rated barrier systems have been crash-tested and certified by a participating independent crash test facility. Barrier system installation must replicate the testing design foundation, bollard spacing and number, beam lengths, etc. Manufacturers also provide a dimensional drawing of the "as-tested" barrier system. Engineer-rated barriers are systems that have been designed and computer-analyzed but not crashed or certified to ASTM or DoS specifications.

These barriers often are interpolated from empirical data received from the results of crash-rated systems. Computer simulation can also manipulate system variations. Engineer-rated systems can differ in terms of foundation dimensions, bollard spacing, and barrier heights and widths. Engineer-stamped drawings show individual changes that have met certain requirements, or certify designs as fully meeting the requirements. The DoD and DoS publish updated lists of approved bollard and barrier vendors. Knowing the threat vehicle, the velocity it is expected to attain, and the acceptable penetration distance provides the ability to select an appropriate barrier for site specific conditions around a facility. The variables considered for different test conditions include the following:.

The three standards are summarized in the next table from which comes this example illustrating use of the ASTM standard, as the increasingly preferred metric:. Security system design still is neither codified nor regulated, in the sense that no universal codes or standards apply to all public and private sector buildings. Government agencies including all military services and private sector organizations have developed numerous security design criteria.

But these must be flexible and change in response to perceived emerging threats. There are numerous standards related to perimeter security see Resource Section. And there are just as many security system designs.
