The struggle against discrimination based on gender identity has also won some significant victories. In 2014, the U.S. Department of Education ruled that schools receiving federal funds may not discriminate against transgender students, and a board within the Department of Health and Human Services decided that Medicare should cover sexual reassignment surgery. Although very few people eligible for Medicare are transgender, the decision is still important, because private insurance companies often base their coverage on what Medicare considers appropriate and necessary forms of treatment for various conditions. Undoubtedly, the fight for greater rights for LGBT (lesbian, gay, bisexual, transsexual) individuals will continue.

Violence

Another running debate questions the easy accessibility of firearms. Between the spring of 1999, when two teens killed twelve of their classmates, a teacher, and themselves at their high school in Columbine, Colorado, and the early summer of 2014, fifty-two additional shootings or attempted shootings had occurred at schools ( [link] ). Nearly always, the violence was perpetrated by young people with severe mental health problems, as at Sandy Hook elementary school in Newtown, Connecticut, in 2012. After killing his mother at home, twenty-year-old Adam Lanza went to the school and fatally shot twenty six- and seven-year-old students, along with six adult staff members, before killing himself. Advocates of stricter gun control noted a clear relationship between access to guns and mass shootings. Gun rights advocates, however, disagreed. They argued that access to guns is merely incidental.

Another shocking act of violence was the attack on the Boston Marathon. On April 15, 2013, shortly before 3:00 p.m., two bombs made from pressure cookers exploded near the finish line ( [link] ). Three people were killed, and more than 250 were injured. Three days later, two suspects were identified, and a manhunt began. Later that night, the two young men, brothers who had immigrated to the United States from Chechnya, killed a campus security officer at the Massachusetts Institute of Technology, stole a car, and fled. The older, Tamerlan Tsarnaev, was killed in a fight with the police, and Dzhokhar Tsarnaev was captured the next day. In his statements to the police, Dzhokhar Tsarnaev reported that he and his brother, who he claimed had planned the attacks, had been influenced by the actions of fellow radical Islamists in Afghanistan and Iraq, but he denied they had been affiliated with any larger terrorist group.

America and the world

In May 2014, President Obama announced that, for the most part, U.S. combat operations in Afghanistan were over. Although a residual force of ninety-eight hundred soldiers will remain to continue training the Afghan army, by 2016, all U.S. troops will have left the country, except for a small number to defend U.S. diplomatic posts.

The years of warfare have brought the United States few rewards. In Iraq, 4,475 American soldiers died and 32,220 were wounded. In Afghanistan, the toll through February 2013 was 2,165 dead and 18,230 wounded. By some estimates, the total monetary cost of the wars in Iraq and Afghanistan could easily reach $4 trillion, and the Congressional Budget Office believes that the cost of providing medical care for the veterans might climb to $8 billion by 2020.

In Iraq, the coalition led by then-Prime Minister Nouri al-Maliki was able to win 92 of the 328 seats in parliament in May 2014, and he seemed poised to begin another term as the country’s ruler. The elections, however, did not stem the tide of violence in the country. In June 2014, the Islamic State of Iraq and Syria (ISIS), a radical Islamist militant group consisting of mostly Sunni Muslims and once affiliated with al-Qaeda, seized control of Sunni-dominated areas of Iraq and Syria. On June 29, 2014, it proclaimed the formation of the Islamic State with Abu Bakr al-Baghdadi as caliph, the state’s political and religious leader.

Section summary

Despite Republican resistance and political gridlock in Washington during his first term in office, President Barack Obama oversaw the distribution of the TARP program’s $7.77 trillion to help shore up the nation’s banking system, and Congress authorized $80 billion to help Chrysler and General Motors. The goals of Obama’s Patient Protection and Affordable Care Act (Obamacare) were to provide all Americans with access to affordable health insurance, to require that everyone in the United States had some form of health insurance, and to lower the costs of healthcare. During his second term, the nation struggled to grow modestly, the percentage of the population living in poverty remained around 15 percent, and unemployment was still high in some areas. Acceptance of same-sex marriage grew, and the United States sharply reduced its military commitments in Iraq and Afghanistan.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
