Convenience Sampling Method00:55

Convenience Sampling Method

8.9K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population.
Convenience sampling is a non-random method of sample selection; this method selects individuals that are easily accessible and may result in biased data. For example, a marketing...

Regulation of Water Intake01:25

Regulation of Water Intake

545
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Water and Mineral Acquisition02:34

Water and Mineral Acquisition

33.1K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Carbonation Shrinkage01:24

Carbonation Shrinkage

161
Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...

Quality of Water01:19

Quality of Water

117
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Area of Science:

  • Public Health
  • Nutritional Science
  • Health Policy

Background:

  • Sugar-sweetened beverages (SSBs) are linked to adverse health outcomes.
  • Community-level interventions are crucial for reducing SSB consumption.
  • Documenting long-term impacts on beverage sales is essential for public health strategies.

Purpose of the Study:

  • To evaluate the long-term effects of a 6-year intervention campaign on beverage sales.
  • To assess changes in sales of sugar-sweetened beverages, diet soda, and 100% juice.
  • To analyze trends in plain water sales following the intervention.

Main Methods:

  • A difference-in-differences regression analysis compared sales data from intervention (Howard County, MD) and control supermarkets (2013-2018).
  • Outcome variables included average weekly sales of regular soda, sports drinks, fruit drinks, diet soda, and 100% juice.
  • Linear regression modeled trends in water sales from 2016-2018.

Main Results:

  • Significant decreases in sales of regular soda (29.7%), fruit drinks (7.5%), and 100% juice (33.5%) were observed between 2012 and 2018.
  • A growing trend of reduced regular soda sales was noted over time.
  • Sales of plain water significantly increased from 2016 to 2018.

Conclusions:

  • Multicomponent, community-based efforts are effective in reducing SSB consumption.
  • Coordinated messaging, community organizing, and policy advocacy can drive sustained improvements in retail beverage sales.
  • Interventions can lead to significant shifts towards healthier beverage choices.
