PROBLEM: (CNN) -- Ollanta Humala, a left-leaning Peruvian politician who promises reforms in education and services to the poor, was sworn in as the nation's president Thursday. In his first address as president, Humala stressed equality, saying he wants Peru to be "a place where everyone enjoys the same rights to abundance and happiness." "Economic growth and social inclusion must march together," he said of his governing philosophy. He succeeds Alan Garcia, who oversaw a period of robust economic growth as president, but who nonetheless was unpopular and criticized for promoting business at the expense of indigenous groups and the environment. Humala, an ex-army officer who ran unsuccessfully for president in 2006 as a leftist ally of Venezuela's Hugo Chavez, reinvented himself as a more moderate leader. He calmed markets and worries that his moderation was a facade to win the election by naming a Cabinet made up of political moderates. The new president has promised to spread the benefits of Peru's economic boom to the poor. He has cited needs to improve the nation's infrastructure, water, sanitation and education, particularly in rural areas. A number of presidents from other Latin American countries, including Ecuador, Chile and Brazil, were on hand to witness the swearing-in ceremony. There was a small oddity during the swearing in of Humala and his two vice presidents, when they all swore allegiance to Peru's 1979 Constitution. That document, however, was replaced in 1993 by a new one drafted during the presidency of strongman Alberto Fujimori. Humala defeated Fujimori's daughter, Keiko, to win the presidency. The slap at the current Constitution resulted in boos and shouts from members of Fujimori's party. Several times in his speech, Humala talked about the importance of unity. "Reality requires a new social contract that makes it possible for all Peruvians to live together," he said. He added that he wants "to be seen as a defender of human rights and of freedom of the press and expression." Other leftist leaders in Latin America, such as Ecuadorian President Rafael Correa and Venezuela's Chavez, have been criticized by press freedom organizations for clamping down on the media. Humala promised change, but warned that it would not be as swift as his critics fear, or as some of his supporters desire. To be lasting, he said, "any changes must be gradual and rational." In another minor controversy, the outgoing president, Garcia, did not attend the swearing-in ceremony to pass the presidential sash to his successor. Garcia, who was also president in a disastrous term from 1985 to 1990, was booed and heckled by Congress when he bid farewell. According to local media, he decided not to attend this time to avoid another round of heckling.

Humala is a former army officer .
He is a leftist who has moderated his stance .
He promises to spread the benefits of Peru's economic boom to the poor .

PROBLEM: Washington (CNN) -- Investigators searching a Washington, D.C., park for a missing 8-year-old girl found the body of a man matching her suspected kidnapper's description, police said Monday. Relisha Rudd has been missing since March 1, when she was last seen with Kahlil Tatum, a 51-year-old janitor at the homeless shelter where Relisha lived. Although the body has not been positively identified, "everything we have is consistent with what (investigators) know about (Tatum's) appearance," D.C. Police Chief Cathy Lanier told reporters Monday, adding that the death was "most likely a suicide." The search for Relisha intensified last week when authorities began combing Kenilworth Park and Aquatic Gardens. The search was prompted by evidence that Tatum had spent time there after Relisha's disappearance. "On March 2, we know that Mr. Tatum purchased, among other items, a carton of black, 42-gallon, self-tie contractor trash bags within the District of Columbia," Lanier said Thursday. "Not long after that purchase, Mr. Tatum was in the area of the aquatic gardens for a period of time." Lanier said after Relisha was last seen, Tatum continued to go to work and was seen around the capital several times between March 2 and March 20. Lanier said Relisha was not with Tatum in any of those sightings. Tatum had not been seen since March 20. Tatum was a janitor for the homeless shelter where Relisha's family had been staying, and it appears Tatum had permission to be with the girl. The case took on new urgency when police discovered the body of Tatum's wife, Andrea Denise Tatum, 51, at a suburban Maryland motel earlier this month. That discovery prompted police to issue an Amber Alert for Relisha. The possible discovery of Tatum's body will not end the search for Relisha, according to Lanier. "We're still here for the reason we came to be here, to find Relisha." The search for the girl has been extensive. Lanier told reporters "hundreds of police officers and firefighter cadets" had been pulled to help with the search, along with divers, underwater cameras, aerial surveillance, search dogs, and cadaver dogs. "Our primary focus here was to find Relisha," Lanier said Monday. "We're not finished. That search is continuing."

PROBLEM: (CNN) -- Having established itself as Apple's top tablet competitor by going smaller and cheaper, Amazon will now go head to head with the category-defining iPad on its own turf. Even as Google's new Nexus 7 challenges the Kindle Fire for dominance in the small-tablet category, Amazon CEO Jeff Bezos on Thursday introduced a new, 8.9-inch Kindle Fire HD. That pits the new device, which will ship in late November, against a device with which Apple has, thus far, squashed all direct competition. No tablet that has tried to match the iPad feature-for-feature has gained more than a token foothold in the market. So, how do the latest version of the iPad and the Kindle Fire HD stack up? Because only a few people have gotten their hands on the new device, some questions can't be answered yet. But here's a look at what we do know so far: . Price . The Fire comes out way ahead on this one, as is to be expected from Amazon, which has targeted customers looking for the basic features of a tablet but not willing to pay Apple's heftier price tag. For $499, the cost of the lowest-end iPad (the 16GB, WiFi-only model), a buyer can get a 32GB version of the Fire HD with a 4G LTE connection on an upgraded cellular network. The 16GB version of the Fire comes in at $299, or $200 less than the comparable iPad. Size . While Amazon obviously closed the gap significantly, the iPad still has a bigger screen than the Fire. Apple's iPad screen measures 9.7 inches diagonally, while the Fire is at 8.9 inches. That's less than the difference between the screen sizes on the iPhone 4S and the larger Samsung Galaxy S III smartphones. (There's speculation the iPhone 5 will have a larger screen). But competition between Apple and Amazon could heat up on another front if rumors that Apple plans to release an "iPad Mini" turn out to be true. Display . Both tablets feature high-definition screens, although the details vary. The iPad's "retina display" featured a total of 3.1 million pixels, with a resolution of 2,048 by 1,536. By contrast, the Fire HD measures 1,920 x 1,200 pixels, with custom features designed to reduce glare and improve color saturation. Both Apple and Amazon boast that the resolution on their tablet is so sharp that it's impossible for the human eye to discern individual pixels. Data plans . Until now, the Kindle Fire has been a WiFi-only device, and some of its new models remain that way. But Bezos announced that the top-end version of the Fire HD is available in 4G. The plan is offered at an attractive price of $50 a year. But that price gets you 250 MB of data per month -- not a lot for a device designed in large part to stream movies and other media. It was unclear Thursday what the charges will be for going over the allotted data. The $50 is well under what AT&T and Verizon charge for a year of data on the iPad. When the first iPad launched, AT&T offered data plans starting at $15 per month, or $180 per year, for 250 megabytes of data. Currently, Verizon offers a variety of plans, from 1GB of data per month for $20 (or $240 per year) all the way up to a massive 8GB per month for $80 ($960). AT&T offers a 250MB per month plan (the same as the Fire) for $15, or $180 per year. For $5 more, customers can get up to 2GB per month. There are obviously lots of permutations of plans customers can seek out for iPads, based on carrier and special offers. It's safe to say Amazon's is going to be less expensive, although it offers a minimal amount of data. Apps . It's hard to compete with Apple's App Store. There are more than 225,000 apps designed specifically for the iPad. Many work to take advantage of its display and screen size. Add the more than a half-million apps that run on mobile devices and you've got a lot from which to choose. Amazon, of course, likes to play up the movies and books that make up its universe of content (and the sale of which make Kindle prices possible). Bezos lumped together more than 22 million movies, TV shows, songs, apps, games, books, audiobooks and magazines available from Amazon's store. He showcased a few, nice-looking new apps. But while the Kindle Fire runs a modified version of Google's Android operating system, it only runs apps available from Amazon. That cuts the number available down to several thousand -- more than enough for many users, but nowhere near what the iPad offers.

Amazon's Kindle Fire HD goes head-to-head with the iPad .
The Fire wins on price, coming in $200 less than Apple's cheapest tablet .
