How many times have parents had to argue with their young son or daughter about getting their face out of their phone and focusing on the world around them? It's completely normal for parents of growing children to be concerned about their child's safety, but their     1     to social media is really harming them.

Social media was created to connect people with others online and has recently been added to smartphones, making it far more accessible than it     2     was. This new way to easily be able to use social media has encouraged children and teens to begin to use sites such as Facebook, Twitter and Instagram frequently. Maturing teens and children are usually very timid when it comes to     3     with their families, which they sometimes view as "annoying”. So, what do these kids use as a solution or a(n)“     4     " The answer is simple social media.

However when they use social media for a large amount of time, parents tend to show concern for their child and blame social media for     5     their attention.

The word, "social", was entered into the term, social media, for a reason. Parents of growing teens don't seem to understand that. When they see their child using Twitter or Instagram they think that they are using it to get away from real world     6     .The truth, however, is that they are using it to connecteded with their close friends, make new friends, and receive information about what is currently happening in the modern world

Children and teens are     7     accused for using social media only for entertainment purposes and for huge amounts of time. Sure everyone who uses social media enjoys contacting their friends and viewing entertaining things, but how come children receive all of the     8     for abusing it? Parents should really think about how social media can help children and teens learn and grow in the real world rather than it just being another    9    .

Social media as a whole has both positive and negative aspects, but after all of the     10     from pre-teens, teens, and parents is put together, it shows that media is actually helping the newer generations in their lives.

Facial Recall

Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people’s names only adds to the stress. A new facial-recognition app could come to the rescue-but privacy experts recommend    1    with caution.

The app, called Social Recall, connects names with faces via smartphone cameras and facial recognition,    2    eliminating the need for formal introductions. “It breaks down these social barriers we all have in terms of    3    the policy of politeness to meet somebody,” says Barry Sandrew, whose start-up, also called SocialRecall, created the app and tested it at an event attended by about 1,000 people.

After receiving an invitation to download SocialRecall from an event organizer, a(n)    4    user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee’s face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have given their    5    And the app's creators say it    6    wipes users’ data after an event.

Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence at Ryerson University in Toronto, commends the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be    7    consequences down the road with that information being used in another context that might come back to    8    you.”

The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone’s face, from either the smartphone’s camera or a photograph, and then    9    it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user’s phone, according to the team behind the app.

Jason Schultz, a professor of clinical law at New York University, who was not involved with the app's creation, remains    10    , “The cost to everyone whom you are surveilling with this app is very, very high, and I don't think it respects the consent politics involved with capturing people's images.”

The Rise of the Smart City

The information revolution is changing the way cities are run and the lives of its residents. Cities have a long way to go before they can be considered geniuses. But they're getting smart pretty fast.

In just the past few years, mayors and other officials in cities across the country have begun to draw on     1     about income, traffic, fires, illness, parking tickets and more—to handle many of the problems of urban life. Whether it's making it easier for residents to find parking places, or giving smoke alarms to the households that are most likely to suffer fatal fires, big-data technologies are beginning to     2     the way cities work.

Cities have just scratched the surface in using data to improve operations, but big changes are already under way in     3     smart cities, says Stephen Goldsmith，a professor of government and director of the Innovations in Government Program at the Harvard Kennedy School.“In terms of city     4     we are at one of the most consequential periods in the last century,” he says.

Although cities have been using data in various forms for decades，the modern practice of civic analytics (民情分析) has only begun to take off past few years, thanks to the     5     changes. Among them: the growth of cloud computing, which dramatically lowers the costs of storing information; new developments in machine learning, which put     6     analytical tools, in the hand of city officials, the Internet and the rise of inexpensive sensors that can keep     7     of vast amount of information such as traffic or air pollution; and the widespread use of smart phone apps and mobile devices that enable citizens and city workers alike to monitor problems and feed information about them back to city hall.

All this data collection raises understandable privacy     8    . Most cities have policies designed to safeguard citizen privacy and prevent the release of information that might     9     any one individual. In theory, anyway. Widespread use of sensors and video can also present privacy risks unless     10     are taken. The technology “is forcing cities to face questions of privacy that they haven't had to face before,” says Ben Green, a fellow at Harvard's BerkmanKlein Center for Internet and Society and lead author of a recent report on open-data privacy.
