[00:00.04]New research suggests
[00:02.60]that nearly half of American teenagers
[00:06.00]say they use the internet "almost constantly."
[00:10.88]The United States-based Pew Research Center
[00:15.48]released a study this month.
[00:18.00]It found that the share of teens who say
[00:21.64]they are online almost all the time
[00:25.00]rose from 24 percent in 2015 to 46 percent.
[00:31.80]The results were based on a Pew public opinion study
[00:37.24]carried out from April 14 to May 4.
[00:41.48]The study involved 1,316 teens aged 13 to 17 years old.
[00:52.68]The research found that about 95
[00:56.48]percent of American teens have smartphones.
[01:02.08]The study also asked teens about their social media behavior.
[01:07.84]It found that the number of teens using Facebook
[01:12.32]has dropped to 32 percent, down from 71 percent in 2015.
[01:19.88]The research shows that teens have moved away from Facebook
[01:25.56]to spend time on the video sharing services YouTube and TikTok.
[01:32.16]About 95 percent of teens said they use Google-owned YouTube,
[01:38.84]while 67 percent said they use TikTok.
[01:44.52]About 62 percent of the teens said they use Instagram,
[01:50.20]which is owned by Facebook's parent company Meta.
[01:54.80]About 59 percent said they use Snapchat.
[01:59.12]Less than one fourth of teens said they use Twitter.
[02:04.64]"A quarter of teens who use Snapchat or TikTok
[02:09.32]say they use these apps almost constantly,
[02:13.52]and a fifth of teen YouTube users say the same," the study said.
[02:20.04]The research found that teen boys are more likely
[02:24.80]than teen girls to use YouTube, or the services Twitch and Reddit.
[02:32.44]Teen girls were more interested
[02:35.12]in using TikTok, Instagram and Snapchat.
[02:40.12]In addition, higher shares of Black and Hispanic teens
[02:44.56]reported using TikTok, Twitter
[02:47.76]and WhatsApp compared to white teens.
[02:52.28]About 54 percent of teens questioned
[02:55.92]said it would be "somewhat hard" to give up social media,
[03:00.36]while 46 percent said it would be "somewhat easy."
[03:05.28]About 25 percent of teen boys said
[03:09.92]giving up social media would be "very easy."
[03:14.08]But just 15 percent of teen girls said the same.
[03:19.92]Experts in online technology behavior
[03:23.48]have accused large technology companies
[03:26.92]of targeting teens with methods to get them
[03:30.72]to spend more time on their social media services.
[03:34.84]One method uses algorithms
[03:38.32]to repeatedly suggest content
[03:41.28]to keep users on the services for longer periods of time.
[03:47.16]Child rights groups and U.S. Congress members
[03:51.00]have warned that heavy use of social media services
[03:55.48]can harm the mental health of young users.
[03:59.60]They have called on large technology companies
[04:03.52]to take steps to reduce such harm.
[04:08.00]Several services – including Instagram, Snapchat and TikTok
[04:13.88]– have introduced features that they say are designed
[04:18.52]to make their services safer and more fitting for young users.
[04:24.88]The tools do offer some help,
[04:27.76]such as blocking unknown individuals from messaging children.
[04:32.60]But experts say the measures also come with weaknesses.
[04:38.48]For example, teens can get around limits if they lie about their age.
[04:44.64]The services also largely depend on parents to enforce rules.
[04:51.04]And the measures do little or nothing to limit inappropriate
[04:56.76]and harmful material suggested by algorithms.
[05:02.40]"These platforms know that their algorithms
[05:06.28]can sometimes be amplifying harmful content,
[05:10.56]and they're not taking steps to stop that," said Irene Ly.
[05:16.20]She is a privacy advisor at the nonprofit group
[05:20.92]Common Sense Media based in San Francisco, California.
[05:26.12]Ly said the more teens keep scrolling,
[05:29.88]the more involved they get in the services.
[05:34.64]She added that the longer teens spend on the services,
[05:39.08]the more profitable the technology companies become.
[05:43.40]"I don't think they have too much incentive
[05:46.96]to be changing that," Ly said.

END OF TRACK. "END OF TRACK." The two men bowed. "Whoever was that person you were talking to?" she enquired, as soon as they stood together. The took of triumph faded from her eyes, she had grown worn and weary. The roses were wilting on the walls, the lights were mostly down now. Hetty, looking in to see if anything was wanted, found herself driven away almost fiercely. I only saw Master Jervie once when he called at tea time, The year 1747 was opened by measures of restriction. The House of Lords, offended at the publication of the proceedings of the trial of Lord Lovat, summoned the parties to their bar, committed them to prison, and refused to liberate them till they had pledged themselves not to repeat the offence, and had paid very heavy fees. The consequence of this was that the transactions of the Peers were almost entirely suppressed for nearly thirty years from this time, and we draw our knowledge of them chiefly from notes taken by Horace Walpole and Lord Chancellor Hardwicke. What is still more remarkable, the reports of the House of Commons, being taken by stealth, and on the merest sufferance, are of the most meagre kind, sometimes altogether wanting, and the speeches are given uniformly under fictitious names; for to have attributed to Pitt or Pelham their[112] speeches by name would have brought down on the printers the summary vengeance of the House. Many of the members complained bitterly of this breach of the privileges of Parliament, and of "being put into print by low fellows"; but Pelham had the sense to tolerate them, saying, "Let them alone; they make better speeches for us than we can make for ourselves." Altogether, the House of Commons exhibited the most deplorable aspect that can be conceived. The Ministry had pursued Walpole's system of buying up opponents by place, or pension, or secret service money, till there was no life left in the House. Ministers passed their measures without troubling themselves to say much in their behalf; and the opposition dwindled to Sir John Hinde Cotton, now dismissed from office, and a feeble remnant of Jacobites raised but miserable resistance. In vain the Prince of Wales and the secret instigations of Bolingbroke and Doddington stimulated the spirit of discontent; both Houses had degenerated into most silent and insignificant arenas of very commonplace business. "It certainly will be. Miss Widgeon," answered Maria, with strictly "company manners." "One who has never had a brother exposed to the constant dangers of army life can hardly understand how glad we all feel to have Si snatched from the very jaws of death and brung back to us." "Just plug at 'em as you would at a crow, and then go on your way whistlin'?" persisted Harry. "Hurroo!" echoed Hennessey; "that's the ticket." "Come forward, keeper," continued the baron, "and state how these arrows came into your hands!" "Yes." HoMEJULIA京香2018下载
