Summary
Companies tend to form supply chain partnerships with firms that are similarly internationalized and from their own country. Understanding these internationalization patterns is crucial for national economic resilience.
Area of Science:
- Economics
- Network Science
- International Business
Background:
- Rising global economic globalization is accompanied by increasing domestic protectionism.
- Understanding drivers and barriers of economic internationalization is vital for national economic productivity and resilience.
- Traditional theories struggle to explain individual firm internationalization, necessitating aggregate pattern analysis.
Purpose of the Study:
- To analyze corporate internationalization patterns using a network-centric perspective.
- To develop and apply novel assortativity metrics for quantifying internationalization tendencies in firm networks.
- To compare internationalization behaviors across different countries.
Main Methods:
- Utilized the Factset Revere dataset capturing global supply chain relationships.
- Designed assortativity metrics based on Newman's coefficient for firm network analysis.
- Quantified companies' internationalization appetite relative to their partners' internationalization levels.
Main Results:
- Identified countries with high and low levels of corporate internationalization.
- Demonstrated that subtle differences in assortativity metrics significantly alter country rankings.
- Revealed that firms generally prefer supply chain partners with similar internationalization levels and from the same country.
Conclusions:
- Corporate internationalization exhibits country-specific patterns and preferences.
- Assortativity metrics provide nuanced insights into internationalization strategies.
- Results inform national economic policy regarding global corporate relationships.

02:03Law of Independent Assortment
62.5K
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

4.5K
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,...

02:00Internal Energy
36.7K
The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

01:31Internal Receptors
74.6K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

01:28Electron Transport Chains
112.0K
The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle.

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...
