The goal of cities which try to be creative is to create conditions which are open enough so urban decision makers can: Rethink potential such as turning waste into a commercial resource; revalue hidden assets such as discovering historic traditions that can be turned into a new product; reconceive and remeasure assets such as understanding that developing social capital also generates wealth; reignite passion for the city by for example developing programmes so people can learn to love their city; rekindle the desire for learning and entrepreneurship by for instance creating learning modules much more in tune with young peoples' desires; reinvest in your talent by not only importing outside talent but fostering local talent; reassess what creativity for your city actually is by being honest about your obstacles and looking at your cultural resources afresh; realign rules and incentives to your new vision rather than seeing your vision as being determined by existing rules; reconfigure, reposition and represent where your city stands and by knitting the threads together to retell your urban story that galvanises citizens to act.

The thesis consists of six chapters. In the first, the technologies of atomic force microscopy and of the measurement elasticity of biomolecules were introduced. In the second, the validity of VSPFM was confirmed by lift mode atomic force microscopy. In this chapter, the height of DNA was measured by lift mode atomic force microscopy, which demonstrated that the method of height measurement of biomolecules by VSPFM was correct and established the foundation of the method of measurement elasticity of biomolecules by vibrating mode scanning polarization force microscopy. In the third chapter, detailed work has been illustrated on the foundation of the method of measurement elasticity of biomolecules by VSPFM. And the compressive elasticity of DNA was measured. In fourth and fifth chapters, the method was applied in the measurement elasticity of proteins. Two proteins elasticity, fibre-like protein α-synuclein and global protein IgG, were measured by VSPFM, through which the method wound its way to the application of biomolecules. In last chapter, the final part of the thesis was a summary. A conclusion of the thesis and a self-comment on my work as a PhD candidate have been made, and expectation about the further works has been addressed.

If an election is to be determined by a majority of a single vote, and that can be procured by a party through artifice or corruption, the Government may be the choice of a party for its own ends, not of the nation for the national good. If that solitary suffrage can be obtained by foreign nations by flattery or menaces, by fraud or violence, by terror, intrigue, or venality, the Government may not be the choice of the American people, but of foreign nations.

The call developmental process of Psittacula agapornis consists of five instinct phases according to its call character. In the first phase （congenital cal1 phase, CCP, 0~12 day of age）, the juveniles only produce single syllable with short syllable length. The second phase（blank-model-forming phase,BMFP, 13~30 day of age） is important for formation of vocal learning pathways. During this phase, the calls characterized by more and longer syllables. In the third phase （call-model-forming phase,CMFP, 31~45 day of age）, the call development is guided by a model system for vocal learning, vocal learning is engendered so that some calls with multi-syllables with UP1 are produced, principal frequency has increased about by 920 cent, the number of note is double that of second phase. The short-term memories are transformed into long-term memories in the forth phase （call-feedback-learning phase,CFLP, 46~90 day of age）. The call of juveniles is a close match to tutor call which accompanied by double various sounds with BS and UP1, and more resonance components were formed. Second principal frequency has increased about by 970 cent, the number of note increases by 2.6~3.0 times. During the fifth phase （excellent call phase,ECP, after 91 d）, vocal motor pathway is developed and the calls are accompanied with most stable, harmonious vari-tone and complex repertoire.
