The term sister refers to a woman, who is either a relative, friend, or both. It is derived from the Old English word sweoster, which derives from Proto-Germanic *swester, a variant of the Proto-Indo-European *swesor. This word is cognate with West Frisian sus, German Schwester, and Latin soror. It also has Gothic origins.
The Sister Study follows the lives of a cohort of women. Every two to three years, these women complete health surveys. This data helps researchers understand how the environment affects women’s risk of developing breast cancer. In addition, researchers can identify factors that affect quality of life after breast cancer diagnosis. The Sister Study was recently reissued on 180-gram purple-marble vinyl. While the album was not commercially successful at the time of its release, it’s still considered one of the best pop albums to emerge from the American underground.
In addition to sharing the same parent company, sister companies are not direct competitors. They produce different product lines and are seldom direct competitors. Their parent company imposes separate branding strategies for sister companies to distinguish them from each other and to target separate markets. Therefore, they often work hand-in-hand. But it is important to note that sisters may not have the same market. Sometimes, it’s a good idea to establish a clear separation between sister companies.
Historically, the term sister and nun have been used interchangeably, but they do have some distinct differences. A nun lives a cloistered life in a monastery, and a sister lives more active, often engaging in apostolic work or teaching classes. In contemporary English, the term “sister” is not commonly used for biological sisters. The term is more widely accessible as a verb and instantly connotes a woman who has made a vow to serve the church.
A sister city relationship can be as simple as a cultural exchange between two cities. Some cities even have formal reciprocal relationships. Sister cities exchange ambassadors and other official recognition. Some of the most common types of exchanges include international conferences, exchange programs, and even shared research projects. While the goals of sister city relationships may vary, they all share the goal of promoting peace and understanding through people-to-people relationships. They also promote economic growth and social progress through the relationship between two cities.
According to a 2010 study, having a sister has many benefits for everyone involved in a family. Sisters provide a unique aspect to a family and make children and adults happier. The study found that individuals with a sister are generally nicer, more giving, and less likely to fight with their siblings. A sister is a gift from parents that is worth cherishing. Not only do sisters provide a second wardrobe, but they also boost physical and mental health.
