Social ties and international entrepreneurship: Opportunities and constraints affecting firm internationalization

Abstract: International entrepreneurship involves the identification and exploitation of opportunities for international exchange. Yet little is known about the entrepreneurial methods used for opportunity recognition. While previous work emphasizes effects operating at the level of the business network, I propose that the recognition of exchange opportunities is a highly subjective process, shaped by entrepreneurs’ existing ties with others. Based on interview data collected from 41 managers, I develop a comprehensive measure for classifying different methods of opportunity recognition. I then use this measure to classify 665 international exchange ventures set up by entrepreneurs in four Chinese cities. In contrast with past research I find virtually no role for blind luck. Although the majority of exchange opportunities were discovered rather than sought, these discoveries were intentional rather than accidental. I also find that entrepreneurs’ idiosyncratic connections with others both promote and inhibit international exchange. Tie-based opportunities lead to higher-quality and more valuable exchanges that are constrained in terms of geographic, psychic and linguistic distance. From this I conclude that entrepreneurial networks have distinct opportunity horizons that limit the reach of tie-based exchanges and potentially lead to sub-optimal internationalization trajectories.

Structural transformation and ferroelectromagnetic behavior in single-phase Bi1−xNdxFeO3 multiferroic ceramics

Abstract: Single-phase Bi1−xNdxFeO3 (BNFOx) (x=0–02) multiferroic ceramics were prepared to study the effects of Nd substitution on their crystal structure and ferroelectromagnetic behavior Rietveld refinement of x-ray diffraction data showed a continual transformation of crystal structure from the rhombohedral structure of BNFOx=0 (BiFeO3) to a triclinic structure in BNFOx=005–015 and a pseudotetragonal structure in BNFOx=0175–02 Ferroelectromagnetic measurements revealed the existence of ferroelectricity with remnant polarization of ∼9μC∕cm2 in BNFOx=0–0175, paraelectricity in BNFOx=02, and weak ferromagnetism with remnant magnetizations of 007–0227emu∕g in BNFOx=015–02 Magnetoelectric coupling was obvious in BNFOx=015–0175 near the Neel temperature of ∼380°C
