Guide to Stockholm University Library

Our library offers different types of studying places and provides a good studying environment.

Zones

The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.

Computers

You can use your own computer to connect to the WiFi specially prepared for notebook computers; you can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.

Group-study Places

If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2-3 people and others can hold up to 6-8 people. All rooms are marked on the library maps.

There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

Storage of Study Material

The library has lockers for students to store course literature. When you have obtained at least 40 credits, you may rent a locker and pay 400 SEK for a year’s rental period.

Rules to Be Followed

Mobile phone conversations are not permitted anywhere in the library. Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls.

Please note that food and fruit are forbidden in the library, but you are allowed to have drinks and sweets with you.

If art preserves the culture of the Crow people, then Crow women are the keepers of that culture, cultivating it to reflect the modern day.

Fashion designer Bethany Yellowtail grew up riding horses and running in the fields and swimming in the river and being around her people in the Crow Nation and Northern Cheyenne Indian reservations in southeastern Montana. She knows first-hand the importance of art to maintaining native traditions. In 2015 she turned that knowledge into her own brand: B. Yellowtail. A year later, she created the B. Yellowtail Collective, made up of native artists, to foster economic opportunities for their communities. Many of those artists are women from different tribes but all of them preserve their culture and move it forward through their medium of choice.

Yellowtail and her team work for the native-owned business that’s rooted in community. Artists within the Collective typically receive 70% of profit from retail sales, and for a portion of the pandemic (流行病) the brand has upped that to 100%. The extra money has, of course, increased artists’ income in the past year, but the relationship is interdependent: without the work of those artists, B. Yellowtail wouldn’t exist and native culture would feel the loss.

Dewanda Little Coyote is Yellowtail’s mother. Family is deeply important to their tribe. So is art, which often runs in the family — and along the matriarchal (母系的) side. Little Coyote picked up her entrepreneurial spirit from her parents, who owned a gift shop. “My parents said, ‘If you have hands, create something. Do something, and make a living off of that,’” she said. After her parents passed away, the artist began learning beading (串珠) earrings herself. Dentalium, a tusk shell often used in native jewelry, caught her eye in particular. “I love it, because back in the day, our Cheyenne women wore a lot of dentalium,” she said. “So I wanted to give a contemporary look to that — to what our ancestors wore.”

Yellowtail herself learned sewing from her aunts and grandmothers before moving to Los Angeles in 2007 to study fashion design. Now, native women support native women — and matriarchal art evolves.

Researchers out of Australia’s Flinders University recently studied various physical reactions during sleep when exposed to noise. They found that certain levels of noise while sleeping, even those below recommended safe levels, may affect a person’s cardiovascular (心血管的) response. When slowly activated during sleep, these responses “could potentially have adverse effects on the cardiovascular system,” said researchers.

Researchers exposed 20 adult participants to various decibels (分贝) of wind farm and road noise while asleep, and then monitored physical responses including blood flow and heart rates as well as sleep awakenings. Although asleep, participants reacted to these noises, as found by the researchers.

For example, a 48-decibel (dB) noise, which is quieter than the 50-dB hum of a refrigerator, was 3. 4 times more likely to cause a change in participants’ pulse wave amplitude (脉搏波振幅), which is a measurement that relates to blood flow. Participants’ heart rates responded to the noise as well. After being exposed to a noise of over 40 dB, they experienced an increase followed by a decrease in their heart rates. The study noted that these sound levels are under the recommended 70 dB limit by the World Health Organization.

Physiological reactions that the study monitored, such as heart rates and blood flow, may root in the proper responses that may be “potentially needed to defend against threats during sleep,” researchers said.

Sleep is typically a time for the body to rest and recover, and noise-caused activation of these cardiovascular responses during sleep may prevent a person from getting the proper amount of healthy sleep they need.

Researchers noted that being exposed to noise pollution during sleep may increase the risk of cardiovascular disease, such as hypertension, heart disease, and other harmful health effects. To help reduce the potential increased health risks caused by frequent noise-caused sleep disturbances, researchers note that their findings help create public policies around noise levels during sleep.
