Heterogeneous world model

Graph neural networks (GNNs) have achieved superior performance and gained significant interest in various domains. However, most of the existing GNNs are considered for homogeneous graphs, whereas real-world systems are usually modeled as heterogeneous graphs or heterogeneous information networks (HINs).

INPRO has developed heterogeneous global model to capture countries’ different policies regarding the back end of the nuclear fuel cycle in regional and global scenarios of nuclear energy evolution and applied in a number of studies performed by participants of the project. This paper will highlight the model and major conclusions obtained in the studies.

A competitive partial-equilibrium spatial model with heterogeneous goods is constructed to evaluate effects of the removal of tariffs, tariff-rate quotas, and sanitary regulations on world poultry trade. The model distinguishes between ìhigh-valueî (mostly white meat) and ìlow-valueî (mostly dark meat) poultry products and simulates the trade flows between eight exporting and importing countries and regions. Removing all barriers simultaneously has larger impact on trade than only removing tariffs and tariff-rate quotas.

A heterogeneous good, spatial partial-equilibrium model with perfect competition affected by non-technical and sanitary trade barriers is used to represent the global poultry sector. There are eight regions in the model: United States (US), Brazil, the EU, Japan, China, Russia, a rest-of-world poultry exporting region (ROWE), and a rest-of- world poultry importing region (ROWM).

To evaluate the policy effects on world poultry trade, a perfectly competitive, spatial partial-equilibrium model with heterogeneous goods is constructed to simulate the trade flows between six key non-composite exporting or importing regions (five countries and the European Union (EU)) and two rest-of-world region aggregates. The model incorporates several extensions of previous work. First, most previous analysis of the economic effects of technical barriers has examined bans on product shipments across a single border (Calvin and Krissoff; Paarlberg and Lee).

Having lived with the World Wide Web for twenty years, surfing the Web becomes a way of our life that cannot be separated. From latest news, photo sharing, social activities, to research collaborations and even commercial activities and government affairs, almost all kinds of information are available and processible via the Web. While people are appreciating the great invention, the father of the Web, Sir Tim Berners-Lee, has started the plan for the next generation of the Web, the Semantic Web....
