Resumen

Las asociaciones público-privadas (APP) en China forman una red compleja con propiedades de mundo pequeño. Los ataques dirigidos, en particular los basados en el grado y la intermediación, son más eficaces para desestabilizar esta red que los ataques aleatorios.

Área de la Ciencia:

Ciencia de Redes
Políticas Públicas
Economía

Sus antecedentes:

La asociación público-privada (APP) es un modelo de contratación en crecimiento para infraestructura y servicios públicos a nivel mundial.
Las APP atraen un interés significativo de los sectores académico e industrial.
Comprender la estructura y la resiliencia de las redes de APP es crucial para una política eficaz.

Objetivo del estudio:

Construir y analizar la complejidad topológica, la robustez y la estructura geográfica de la red de accionistas de APPs de China.
Identificar las características clave de la red, incluido el comportamiento de mundo pequeño y la distribución de grado.
Evaluar la vulnerabilidad de la red a diferentes estrategias de ataque.

Principales métodos:

Construcción de una red de accionistas de APPs para China.
Análisis de la topología de la red utilizando métricas de complejidad y de mundo pequeño.
Aplicación de múltiples medidas de centralidad para evaluar la robustez de la red bajo ataques dirigidos y aleatorios.
Examen de la distribución geográfica y la jerarquía espacial de la red.

Principales resultados:

La red de accionistas de APPs de China exhibe características de mundo pequeño y una distribución de grado de cola pesada.
Los ataques dirigidos (basados en grado e intermediación) son significativamente más efectivos para desestabilizar la red que los ataques aleatorios.
La red muestra una estructura geográfica jerárquica con Beijing como centro principal y las capitales provinciales como centros regionales.

Conclusiones:

Los hallazgos resaltan la vulnerabilidad de las redes de APPs a la desestabilización estratégica.
La estructura jerárquica sugiere una influencia concentrada y riesgos sistémicos potenciales.
Las implicaciones para la formulación de políticas enfatizan la necesidad de una mayor supervisión de las empresas dentro de los proyectos de APP para garantizar la estabilidad y la eficiencia.

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Levels of Communication II: Organizational, Public, and Group Dynamics

Effective communication is the foundation of a good organization. Communication is the lifeblood of an organization that connects the group with messages. In an organization, communication occurs in upward, downward, and horizontal lines. Downward communication travels from the administrative and senior levels to the staff through official channels such as manuals, rules and regulations, and organizational charts. Staff members initiate upward communication, which is addressed to executives and...

Protein Complex Assembly

Protein Complex Assembly

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Protein Complexes with Interchangeable Parts

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...
