概括
有更多少数民族学生的学校树冠更大,但需要高的地区的优先级较低. 种植树木的举措需要解决这些城市树冠不平等的学生健康.
科学领域:
- 环境健康 环境健康
- 城市规划是城市规划.
- 皮肤病学 皮肤病学
背景情况:
- 树冠提供显著的环境和皮肤学益处,特别是在学校校园.
- 现有的种植树的举措可能会无意中加剧在获得这些福利方面现有的差距.
- 社会经济因素可能会影响学校园区树冠阴影的分布.
研究的目的:
- 为了调查奥斯,德克萨斯州公立学校校园的树冠阴影与学生社会经济地位之间的关系.
- 评估当前的树木倡议是否有效地解决了树冠分布中发现的不平等问题.
主要方法:
- 2006年和2022年使用ArcGIS量化奥斯独立学区112个校园的树冠覆盖面的横截面研究.
- 树冠百分比与学生免费和减价餐的资格 (FRM) 的比较.
- 基于奥斯树优先级地图的"低优先级"与"高优先级"社区的FRM学生百分比分析.
主要成果:
- 与大多数FRM学生 (12.4%) 相比,具有较高少数民族比例的学校,符合FRM学生的树冠显著增加 (19.9%),而不是大多数FRM学生 (12.4%).
- 在"低优先级" (23.8%) 和"高优先级" (62.2%) 区域之间,在FRM有资格的学生百分比中发现了显著的差异.
- 这些发现表明社会经济地位,种族和树冠分布之间的复杂关系.
结论:
- 纠正公立学校学生在树冠访问方面的不平等,需要有针对性的干预.
- 使用像奥斯树优先地图这样的名称可以帮助引导公平的树种工作.
- 鼓励涉及皮肤科医生,医疗保健专业人员和城市规划人员使用GIS促进环境正义的跨学科研究.

Survival Tree
84
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Light Acquisition
8.5K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Adaptations that Reduce Water Loss
25.6K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

The Bronchial Tree
2.5K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Threats to Biodiversity
22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
