- 酒精政策研究 酒精政策研究
- 饮食影响研究 饮食影响研究
背景情况:
- 苏格兰在2018年实施了最低单位价格 (MUP),以制过度饮酒.
- 人们担心,增加酒精消费可能会对食物选择和饮食质量产生负面影响.
研究的目的:
- 确定MUP与饮食摄入量之间的关联,包括能量,营养素和整体饮食质量.
- 分析MUP对特定食品和营养素采购的影响.
主要方法:
- 使用家庭购买数据进行差异差异分析 (Kantar Worldpanel).
- 1987年苏格兰家庭与英格兰北部6064个家庭在MUP实施前后进行比较.
- 对各种家庭和时间因素进行调整的Poisson伪最大概率回归.
主要成果:
- 从食品和饮料中购买糖的比例减少了1.6%,相当于每个成年人每周购买糖8g.

02:23Alcohols from Carbonyl Compounds: Reduction
12.0K
Reduction is a simple strategy to convert a carbonyl group to a hydroxyl group. The three major pathways to reduce carbonyls to alcohols are catalytic hydrogenation, hydride reduction, and borane reduction.
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...

01:16Hypothesis Test for Test of Independence
7.4K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...
