Compass01:23

Compass

564
The compass is a fundamental instrument that operates by aligning its magnetic needle with Earth's magnetic field. This alignment facilitates navigation and orientation, offering a means to determine direction relative to magnetic north. However, the magnetic needle points to magnetic north, which differs slightly from true geographic north due to magnetic declination, which is the angular deviation between these two points. Declination varies based on geographic location and shifts over time...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

228
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Pareto Chart00:52

Pareto Chart

7.3K
A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

Pie Chart01:04

Pie Chart

15.0K
A pie chart (or a pie graph) is a circular graphical chart or a pictorial representation of categorical data. It is divided into slices of pie each indicating numerical proportions. It is also used to show the relative sizes of data in a single chart.
In a pie chart, the central angle, the arc length of each slice, and the area are directly proportional to the quantity or percentage it represents. Some real-world examples that can be depicted using pie charts include marks obtained by students...

Design Example: Marking Boundaries of a Site Using a Compass01:12

Design Example: Marking Boundaries of a Site Using a Compass

123
Marking site boundaries using a compass is a precise surveying technique that ensures the accuracy of boundary delineation. The process begins by using provided site details, including the bearings and lengths of each boundary line. The initial step involves calculating latitudes and departures for all sides of the site. This computation verifies that the traverse is free of errors, ensuring a closed and accurate boundary.The process starts at a known point, such as Point A, which is often...

Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

253
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Area of Science:

  • Public Health
  • Health Policy
  • Epidemiology

Background:

  • Leaders face challenges balancing economic/social restoration with public health during the COVID-19 pandemic.
  • The COVID Compass project aims to guide local decisions by tracking policies and their impacts.
  • Key outcomes include health metrics, economic trends, and social hardship indicators.

Purpose of the Study:

  • To track state and local policies and their impact on health, economic, and social hardship outcomes.
  • To provide data for informed decision-making during the COVID-19 pandemic.
  • To develop a balanced set of indicators for monitoring pandemic-related harms.

Main Methods:

  • Selected local-level health, economic, and hardship outcomes.
  • Linked outcomes to local actions mitigating COVID-19 effects and economic hardship.
  • Planned frequent data releases (weekly/monthly) on outcomes and actions.

Main Results:

  • Initial analytic and visualization prototypes for COVID Compass are under development.
  • Prototypes are being created at national, state, and local levels.
  • The project is progressing towards a functional data platform.

Conclusions:

  • An integrated database platform is needed to link policies, actions, and outcomes.
  • This platform will provide a comprehensive view for decision-makers and citizens.
  • It will enable more effective monitoring and mitigation of pandemic-related harms.
