Revisiting the OLI Paradigm: The Institutions, the State, and China's OFDI
We propose a modified theoretical framework based on John Dunning’s classical OLI paradigm in the international business literature to analyze Chinese firms’ fast-growing and aggressive outward foreign direct investment (OFDI). In particular, from an institutional perspective, we suggest a “state-stewardship” view to incorporate state institutions into the OLI paradigm. This paper supplements our earlier work (Ren, Liang, and Zheng, 2011) on identifying the formal institutional determinants of Chinese firms’ OFDI motivations and strategies, by further looking at the impact of direct and indirect policies, and the OFDI state-controlled financial intermediaries. Under our modified OLI framework we also examine the potential concerns on China’s state-backed OFDI and its implication on long-term sustainability.outward foreign direct investment, institutions, state-stewardship view, OLI paradigm
Better synchronizability predicted by a new coupling method
In this paper, inspired by the idea that the hub nodes of a highly
heterogeneous network are not only the bottlenecks, but also effective
controllers in the network synchronizing process, we bring forward an
asymmetrical coupling method where the coupling strength of each node depends
on its neighbors' degrees. Compared with the uniform coupled method and the
recently proposed Motter-Zhou-Kurth method, the synchronizability of scale-free
networks can be remarkably enhanced by using the present coupled method.Comment: 6 pages, 6 figures; to be published in EPJ
Detectable MeV neutrinos from black hole neutrino-dominated accretion flows
Neutrino-dominated accretion flows (NDAFs) around rotating stellar-mass black
holes (BHs) have been theorized as the central engine of relativistic jets
launched in massive star core collapse events or compact star mergers. In this
work, we calculate the electron neutrino/anti-neutrino spectra of NDAFs by
fully taking into account the general relativistic effects, and investigate the
effects of viewing angle, BH spin, and mass accretion rate on the results. We
show that even though a typical NDAF has a neutrino luminosity lower than that
of a typical supernova (SN), it can reach
peaking at MeV, making them potentially detectable with the upcoming
sensitive MeV neutrino detectors if they are close enough to Earth. Based on
the observed GRB event rate in the local universe and requiring that at least 3
neutrinos are detected to claim a detection, we estimate a detection rate up to
(0.10-0.25) per century for GRB-related NDAFs by the Hyper-Kamiokande
(Hyper-K) detector if one neglects neutrino oscillation. If one assumes that
all Type Ib/c SNe have an engine-driven NDAF, the Hyper-K detection rate would
be (1-3) per century. By considering neutrino oscillations, the
detection rate may decrease by a factor of 2-3. Detecting one such event would
establish the observational evidence of NDAFs in the universe.Comment: 7 pages, 2 figures, 2 tables, accepted for publication in PR
