Summary
De-globalization trends are reshaping international investment networks. Countries are forming smaller, closer regional financial communities, indicating a shift towards geographically influenced cooperation.
Area of Science:
- Economics
- International Finance
- Network Theory
Background:
- Increasing global protectionism and market-seeking behaviors challenge traditional global trade.
- Existing studies on international investment networks often lack detailed bilateral data.
Purpose of the Study:
- To analyze the impact of de-globalization on international investment relationships.
- To examine the structural evolution of the international investment network (IIN).
Main Methods:
- Systematic analysis of the IIN across 127 economies (2005-2016).
- Estimation of bilateral international investment data using a matrix-based iteration approach.
- Application of complex network theory and development of a 'node similarity' indicator.
Main Results:
- The IIN exhibits heterogeneous and hierarchical structures, with most economies forming tight, regional groups.
- A trend towards smaller, closer communities and developing regional financial cooperation is observed.
- The IIN structure is evolving geographically, with increasing community division over time.
Conclusions:
- De-globalization influences the IIN structure geographically, fostering regional financial cooperation.
- Regional cooperation positively impacts international investment.
- Governments should support liberal financial policies and enhance regional financial cooperation.

02:55The Evidence for Evolution
47.7K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

01:28Internal Loadings in Structural Members: Problem Solving
1.7K
When designing or analyzing a structural member, it is important to consider the internal loadings developed within the member. These internal loadings include normal force, shear force, and bending moment. Engineers can ensure that the structural member can support the applied external forces by calculating these internal loadings.
To illustrate this, let's consider a beam OC of 5 kN, inclined at an angle of 53.13° with the horizontal and supported at both ends. Determine the internal...

01:31Internal Receptors
74.4K
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.

Wood's structural properties derive from fibers aligned along the tree's length, contributing significantly to its mechanical strength. Wood exhibits up to twenty times greater tensile strength along these fibers compared to across them, and generally shows better performance under compression than tension. The length of fibers varies, with hardwoods having fibers around one twenty-fifth inch long and softwoods ranging from one-eighth to one-third inch.

Introduction:
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.

01:54Convergent Evolution
31.6K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.
