Summary
Global non-traditional security (NTS) challenges surged in 2012 and 2016, driven by terrorism and instability. NTS risks are now more dispersed globally, requiring adaptive cross-border governance.
Area of Science:
- Global Security Studies
- International Relations
- Data Science
Background:
- Non-traditional security (NTS) challenges have escalated globally since the 21st century.
- Existing research often lacks a comprehensive, data-driven global perspective on NTS evolution.
Purpose of the Study:
- To analyze the spatiotemporal evolution of global non-traditional security (NTS) issues from 2000 to 2023.
- To quantify the frequency and impact of NTS activities using novel indicators.
- To identify distinct phases and evolving patterns of NTS challenges worldwide.
Main Methods:
- Utilized event data from the Global Database of Events, Language, and Tone (GDELT).
- Constructed a global panel dataset for 153 countries (2000-2023).
- Developed and applied the CEN (count event number) and NSII (NTS impact index) indicators to measure NTS scale and severity.
Main Results:
- Identified five distinct phases in global NTS evolution, with peaks in 2012 and 2016.
- Peaks were primarily driven by terrorism and social instability in the Middle East, South Asia, and Africa.
- Observed a shift in NTS hotspots towards more dispersed and transregional patterns, indicating risk diffusion.
Conclusions:
- NTS risks are increasingly interconnected and transregional, necessitating adaptive, cross-border governance.
- Continuous monitoring mechanisms are crucial for effective policy responses to evolving NTS threats.
- The study provides a data-driven framework for tracking and understanding global NTS dynamics.

Entropy Changes Accompanying Specific Processes

Entropy, a measure of disorder in a system, changes during phase transitions like freezing or boiling. At the transition temperature Ttrs, where two phases are in equilibrium, the phase transition is a reversible process. The entropy change can be calculated from a substance's enthalpy of transition using the equation ΔStrs = ΔtrsH /Ttrs.When a perfect gas expands isothermally from one volume to another, entropy increases logarithmically with volume. Conversely, isothermal compression...

State Space Representation

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
