概括
对养猪场的暴露是复杂的,不同的指标给社区带来了不同的风险概况. 量身定制的空间指数为潜在的环境和健康影响提供了细微的见解.
科学领域:
- 环境健康 环境健康
- 空间流行病学 空间流行病学
- 环境正义 环境正义
背景情况:
- 靠近养猪场是评估社区接触污染物,气味和潜在健康影响的常见替代品.
- 然而,暴露的定义是复杂的,导致不同的风险概况,取决于评估方法.
- 一般的脆弱性指标,如CDC的社会脆弱性指数 (SVI) 和环境正义指数 (EJI),可能无法完全捕捉特定的环境暴露.
研究的目的:
- 开发和评估空间显式指标来量化社区对北卡罗来纳州猪场的暴露.
- 评估这些猪场特定暴露指数和通用脆弱性指数 (SVI,EJI) 之间的相关性.
- 了解不同暴露定义如何影响风险社区的识别.
主要方法:
- 在人口普查区一级开发了三个空间显式指标:家庭近距离 (IDx1),猪和湖的共同养殖 (IDx2) 和猪密度 (IDx3).
- 在这些猪场指数和CDC的SVI和EJI之间进行了相关性分析.
- 用地理绘图和统计分析来比较指数及其关系.
主要成果:
- 三个猪场暴露指数 (IDx1,IDx2,IDx3) 显示了彼此的不同相关性.
- 猪场特定指数与CDC SVI和EJI的相关性有限 (≤0.3),表明了不同的风险指标.
- 在农村地区观察到猪场指数和CDC SVI之间的轻微相关性,这表明这些地区的脆弱人口可能更集中在农场附近.
结论:
- 与一般的脆弱性指标相比,猪场特定的暴露指数提供了更为量身定制的潜在风险理解.
- 不同的暴露指标可以导致关于哪些社区面临风险最大的不同结论.
- 需要一个层次框架来量化和比较环境暴露,考虑风险修饰因素和个人级数据,以便准确的风险评估和有针对性的干预措施.

Cloning of Dolly the Sheep
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter telomeres than other...
Censoring Survival Data
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different reasons...
