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.

4 . Hazel Mayfield usually cooks the Thanksgiving meal for her extended family in Houston, Texas. She usually welcomes friends and neighbors who are eager to taste her fried turkey, green bean casserole, candied yams, homemade cornbread dressing, and dirty rice-just a few of her signature dishes. Known as Sugar Mama, because her grandchildren think she’s so sweet, the 91-year-old typically likes to do her own shopping for the ingredients to make her special dishes.

“My mother is the head cook of the family,” said Panulette Mouton, Mayfield’s daughter. “Because of her reputation, you know, there’re people in and out all day and every family comes through. They want to get some of Sugar Mama’s cooking, and some of them would like to learn from her how to cook the food.”

But Mayfield hasn’t been to the grocery store since March. And there is little about Thanksgiving in 2020 that’s usual. Because of Covid-19, the deadly virus that has killed millions in the U.S. and spoiled life around the world, everything is different. Since limiting close face-to-face contact with others is the best way to reduce its spread, hundreds of thousands of American families have re-imagined the holiday with virtual celebrations and canceled or delayed travel plans. There can only be small gatherings with people in their households in response to COVID-19.

This year, Mayfield’s family members, without exception, are lamenting the absence of a big gathering. They’ve explained to their young children and grandchildren why this year’s Thanksgiving is different. Mayfield’s youngest daughter, Michelle Sanders, says it’s tough to help her grandchildren understand why they can’t see some of their other family members and why they have to stay at home, celebrating Thanksgiving all by themselves.

“It’s really hard, trying to explain to them,” Sanders said. “When-you’re talking to them and they want to come over, you have to tell them no. They really don’t know how to be careful.” Sanders added, “And, they don’t understand that, being three, four, and six, you know they don’t really understand that. So, it’s...it’s really, really hard, and heartbreaking.”

5 . Portraits as Art

According to a dictionary, portraiture is “a representation (描绘) of a person, especially of the face by drawing or painting a likeness.” However, this definition neglects the complexities of portraiture. Portraits are works of art that engage with ideas of identity rather than just a likeness. These concepts of identity involve social rank, gender, age, profession, character of the subject, etc. It is impossible to copy all the aspects of identity. Therefore, portraits reflect only certain qualities of subjects. Portrait art has also undergone significant shifts in artistic practice. The majority of portraits are the outcome of current artistic fashions and favored styles. Therefore, portrait art is an art category providing various engagement with social, psychological, and artistic practices and expectations.

Since portraits are different from other art categories, they are worthy of separate study. During their production, portraits require the presence of a specific person, or an image of the individual. In many instances, the production of portraiture has required sittings, which result in interaction between the subject(s) and the artist throughout the creation of the work. In certain instances, portrait artists depended on a combination of different involvement with their subjects. If the sitter can’t sit in the studio regularly, portraitists could use his or her photographs. In Europe, during the seventeenth and eighteenth century, the sitting time was sometimes decreased by focusing only on the head. Theoretically, portraitists could work from impressions or memories when creating a painting, but this rarely occurred according to documented records. Nonetheless, whether the work is based on model sittings, copying a photograph, or using memory, the process of painting a portrait is linked with the model’s attendance.

Furthermore, portrait painting can be distinguished from other artistic categories by its connection with appearance, or likeness. As such, the art of portrait painting got a reputation for imitation instead of for artistic innovation. Based on Renaissance art theory, portraiture was related to the level of a mechanical exercise as opposed to a fine art. Michelangelo’s well-known protest against portraits is only one example. During the nineteenth and twentieth centuries, the attitude to portraiture was critical. Even so, artists from around the globe persisted in painting portraits despite their theoretical objections. Picasso, for example, became widely-known for cubist still-life painting (立体派静物画) early in his career, but some of his early experiments in this new style were his portraits of art dealers.
