概括
新的轻轨交通 (LRT) 并没有显著增加附近居民的整体体力活动或交通使用. 然而,它导致了步行特别用于过境访问的适度增加.
科学领域:
- 城市规划和公共卫生
- 运输科学 运输科学
- 身体活动研究研究.
背景情况:
- 增加交通基础设施可以促进体力活动,如果它鼓励积极前往车站.
- 很少有研究对附近居民的身体活动和交通使用变化进行了纵向评估.
研究的目的:
- 检查新轻轨交通 (LRT) 对居住在新车站附近或更远的居民体力活动和交通使用的影响.
- 为了比较体力活动 (总体,步行,运输相关) 和运输使用在LRT实施之前和之后的变化.
主要方法:
- 招募了722名在西雅图/金县新LRT站附近 (暴露) 和远离 (未暴露) 的居民.
- 在LRT开放前和3-4年后使用加速度计,GPS,旅行日志和调查评估参与者.
- 使用差异分析来比较暴露和未暴露组之间的纵向变化.
主要成果:
- 两组之间没有观察到整体体力活动,休步行或实用步行的显著差异变化;大多数参与者活动减少.
- 与没有暴露的组相比,在暴露于LRT的组中发现了与过境相关的步行时间的适度增加 (<2分钟/天).
- 在居住在新LRT附近和远处的居民之间,没有检测到总体运输使用的实质性差异变化.
结论:
- 新轻轨交通 (LRT) 暴露并没有显著改变附近居民的整体交通使用或体力活动水平.
- 在暴露于新LRT的居民中,观察到过境通道的步行量略有增加.
- 该研究强调,尽管靠近新的运输基础设施,但对整体体力活动的影响有限.

Longitudinal Studies
494
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Travelling Waves
6.9K
A wave is a disturbance that propagates from its source, repeating itself periodically, and is typically associated with simple harmonic motion. Mechanical waves are governed by Newton's laws and require a medium to travel. A medium is a substance in which a mechanical wave propagates, and the medium produces an elastic restoring force when it is deformed.
Water waves, sound waves, and seismic waves are some examples of mechanical waves. For water waves, the wave propagation medium is...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Traveling Waves: Lossless Lines
471
The provided content explores the behavior of traveling waves on single-phase lossless transmission lines. It begins with a single-phase two-wire lossless transmission line of length Δx, characterized by a loop inductance LH/m and a line-to-line capacitance C F/m. These parameters result in a series inductance LΔx and a shunt capacitance CΔx.

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...
