Through social media, historical content is presented in a more engaging and relevant manner, contributing to a shift in how individuals interact with and interpret historical information.
What are different patterns of refugees and migrants utilization?
5 answers
Refugees and migrants exhibit distinct patterns in healthcare utilization. Research in Austria shows that refugees have notably higher healthcare expenditures compared to natives, especially in the first year post-arrival, indicating generally poorer health status. In Sweden, young refugees and non-refugee immigrants have lower psychiatric care utilization rates for most disorders compared to Swedish-born individuals, except for conditions like schizophrenia and stress-related disorders. Additionally, a study in the Nyarugusu refugee camp in Tanzania revealed that refugees underwent a majority of surgical procedures, with a significant increase in surgeries post a large refugee influx in 2015, impacting host population utilization differently. Arab refugees in the United States also demonstrate higher healthcare utilization rates compared to immigrants, with refugees reporting a greater need for services.
How does the amount of food waste vary by sector (i.e., households, restaurants, grocery stores)?
5 answers
Household food waste varies by sector due to different factors. Research indicates that online grocery shopping is associated with greater quantities of food waste, particularly fruit and vegetable waste. Additionally, proximity to different types of food stores influences household food waste, with increased distance to large food stores leading to more waste, especially among households without cars. In China, household food waste proportions are highest for fruits and vegetables, influenced by factors like label cognition and population size. Moreover, urban households in Nigeria exhibit significantly higher monthly food waste proportions compared to rural households, with reasons such as leftovers and lack of proper storage differing between the two sectors. Understanding these sector-specific dynamics is crucial for developing targeted interventions to reduce food waste effectively.
