The Political Consequences of Ambivalence: The Case of Democratic Reform in Hong Kong

Recent research has shown that attitudinal ambivalence has importantimplications on political attitudes and behavior. The conceptholds one of the keys to understanding complicated and seeminglycontradictory opinions of the public. This article examinesambivalence in public opinion regarding democratic reform inHong Kong. Analysis of a representative survey (N = 600) showsthat common citizens indeed have a significant degree of ambivalencetoward the government's political reform bill proposed in 2005.Regarding consequences, objective ambivalence is shown to havegreater predictive power than subjective ambivalence. The formerrelates negatively to attitude extremity and weakens the attitude–behaviorlinkage. However, contrary to the usual finding in the literature,objective ambivalence also relates positively to protest participationintention. The theoretical and social implications of the findingsare discussed. Received for publication June 29, 2007. Accepted for publication October 8, 2008.

Microfluidic fabrication of polymeric core-shell microspheres for controlled release applications

We report a facile and robust microfluidic method to fabricate polymeric core-shell microspheres as delivery vehicles for biomedical applications. The characteristics of core-shell microspheres can be precisely and easily tuned by manipulating the microfluidic double emulsion templates. The addition of a shell can significantly improve the versatility as well as functionality of these microspheres as delivery vehicles. We demonstrate that the nature of the shell material plays an important role in the properties of the core-shell delivery vehicles. The release kinetics is significantly influenced by the material of the shell and other characteristics such as the thickness. For example, by adding a poly(lactic-co-glycolic acid) (PLGA) shell to an alginate core, the encapsulation efficiency is enhanced and undesired leakage of hydrophilic actives is prevented. By contrast, adding an alginate shell to PLGA core can lead to a reduction of the initial release rate, thus extending the release period of hydrophobic actives. Microfluidic fabrication enables the generation of precisely controlled core-shell microspheres with a narrow size distribution, which enables the investigation of the relationship between the release kinetics of these microspheres and their characteristics. The approach of using core-shell particles as delivery vehicles creates new opportunities to customize the release kinetics of active ingredients.
