Healthy See, Healthy Do
Visit the grocery store on an empty stomach, and you will probably come home with a few things you did not plan to buy. But hunger is not the only cause of additional purchases. The location of store displays (摆放) also influences our shopping choices.1.
The checkout area is a particular hotspot for junk food. Studies have found that the products most commonly found there are sugary and salty snacks.2. A 2012 study in the Netherlands found that hospital workers were more likely to give up junk food for healthy snacks when the latter were more readily available on canteen shelves, for example. In 2014 Norwegian and Icelandic researchers also found that replacing unhealthy foods with healthy ones in the checkout area significantly increased last-minute sales of healthier foods.
3. It has been working with more than 1,000 store owners to encourage them to order and promote nutritious foods. “We know that the stores are full of cues (暗示) meant to encourage consumption,” says Tamar Adjoian, a research scientist at the department, “Making healthy foods more convenient or appealing can lead to increased sales of those products.”
Adjoian and her colleagues wondered if such findings would apply to their city’s crowded urban checkout areas, so they selected three Bronx supermarkets for their own study. 4. Then they recorded purchases over six three-hour periods in each store for two weeks.
Of the more than 2,100 shoppers they observed, just 4 percent bought anything from the checkout area. Among those who did, however, customers in the healthy lines purchased nutritious foods more than twice as often as those in the standard lines.5. The findings were reported in September in the Journal of Nutrition Education and Behavior.
The potential influence may seem small, but Adjoian believes that changing more checkout lines would open customers’ eyes to nutritious, lower-calorie foods. Health department officials are now exploring ways to expand healthy options at checkout counters throughout New York City.
A. These foods give people more energy.
B. They bought unhealthy foods 40 percent less often.
C. And it may make or break some healthy eating habits.
D. The supermarkets began to offer nutritious, lower-calorie foods.
E. These findings caught the attention of New York City Department of Health.
F. They replaced candies and cookies with fruits and nuts near the checkout counter.
G. And a few studies have suggested that simply swapping in healthier options can change customer behavior.
Overtourism: A growing global problem
The summer holidays are in full swing—and protests against overtourism have begun in a number of popular European cities. Barcelona, in particular, is at the centre of these mounting concerns about the rapid growth of tourism in cities, especially during peak holiday periods. In fact, there were 30 million overnight visitors in 2017, compared to a resident population of 1,625,137 in Barcelona.
While many tourists want to “live like a local” during their visits, the residents of many tourism-dependent destinations are seeing the unique sense of place that characterised their home towns vanish beneath a wave of souvenir shops, crowds, tour buses and noisy bars. Overtourism is harming the landscape, damaging beaches, and pricing residents out of the housing market. It is a hugely complex issue that is often oversimplified.
It can have an impact in multiple ways. The international cruise(游轮) industry, for example, delivers thousands of passengers daily to destination ports. While comparatively little is returned to communities, cruise activity creates physical and visual pollution.
City residents also bear the cost of tourism growth. As cities transform to offer service to tourists, the global travel supply chain advances. This goes with increasing property speculation(房产投机) and rising costs of living for local communities. Airbnb, for example, has been accused of reducing housing affordability and displacing residents.
In addition, overcrowding and the establishment of typical tourism-focused businesses, such as clubs, bars and souvenir shops, overpower local businesses—and noisy and unmanageable tourist behaviour is common. This weakens the uniqueness of destinations and leads to crowd and waste management pressures.
Clearly, tourism brings jobs, investment and economic benefits to destinations. But overtourism occurs when tourism expansion fails to acknowledge that there are limits. Local government and planning authorities have so far been powerless to deal with the irresistible influence of the global tourism supply chain. This has led to widespread “tourist-phobia”—first described by Manuel Delgado more than a decade ago as a mixture of rejection, mistrust and disrespect for tourists.
Dealing with overtourism must now be a priority. Managing the flow of tourists seems an improbable and unwelcome task. But some cities have taken extreme measures to limit the effects of overtourism, including the introduction of new or revised taxation arrangements, fines linked to new local laws, and “demarketing”, whereby destinations focus on attracting fewer, high-spending and low impact tourists, rather than large groups.
Overtourism is a shared responsibility. City administrators and destination managers must acknowledge that there are definite limits to growth. Putting the wellbeing of local residents above the needs of the global tourism supply chain is vital. Primary consideration must be given to ensuring that the level of visitation fits within a destination’s capacity. We need to urgently rethink the way cities are evolving to uphold the rights of their residents.

Love the way you walk
Listen carefully to the footsteps in the family home, and you can probably work out who is walking about. The features most commonly used to identify people are faces, voices and fingerprints. But the way they walk is also a giveaway.
Researchers have used video cameras and computers to analyze people’s gaits, and are now quite good at it. But translating such knowledge into a practical identification system can be tricky. Cameras are often visible, are difficult to set up, require good lighting and may have their view blocked by other people. A team led by Dr. Ozanyan and Dr. Scully have been looking for a better way to recognize gait. Their answer: pressure-sensitive mats.
Such mats are nothing new. They have been part of security systems. But Ozanyan and Scully use a complicated version that can record the amount of pressure applied in different places as someone walks across it. These measurements form a pattern unique to the walker. The researchers turned to an artificial-intelligence system to recognize such patterns, and it seemed to work. In a study in 2018, they tested the system on a database of footsteps of 127 people. They found its error rate in identifying who was who was a mere 0.7%. And Scully says even without a database of footsteps to work with, the system can determine someone’s sex and, with reasonable accuracy, a subject’s age.
One application of the mat-based gait-recognition system might be in health care, particularly for the elderly. A mat placed in a nursing home or an old person’s own residence could monitor changes in an individual’s gait that indicates certain illnesses. That would provide early warning of someone being at greater risk of falling over.
Gait analysis might also be used as a security measure in the workplace, monitoring access to restricted areas, such as parts of military bases, server farms or laboratories dealing with dangerous materials.
Perhaps the most interesting use of the mats, though, would be in public places, such as airports. For that to work, the footsteps of those to be recognized would need to have been stored in a database, which would be harder to arrange than the collection of photographs and fingerprints that existing airport security systems rely on. Many aircrew or preregistered frequent flyers would welcome anything that speeded up one of the most tiresome parts of modern travel.
