One of the most contentious areas in creativity theory is the question of domain specificity. How we conceptualize creativity — as something that transcends content domains, or as something that varies depending on the domain in question — has important implications for both creativity research and creativity training programs. The Amusement Park Theoretical (APT) model of creativity is the first creativity theory to successfully bridge the gap between these contrasting views of creativity. The APT model uses the metaphor of an amusement park to explore creativity. There are four stages: Initial requirements, general thematic areas, domains, and micro‐domains. The first level (initial requirements) is very general, and each subsequent level gets more and more domain‐specific. The APT model can provide a powerful framework for creativity assessment, selection of students for gifted education programs, and the development of creativity training programs. 相似文献

In this work, we introduce a method for the soft-lithography-based fabrication of rigid microstructures and a new, simple bonding technique for use as a continuous-flow cell lysis device. While on-chip cell lysis techniques have been reported previously, these techniques generally require a long on-chip residence time, and thus cannot be performed in a rapid, continuous-flow manner. Microstructured microfluidic devices can perform mechanical lysis of cells, enabling continuous-flow lysis; however, rigid silicon-based devices require complex and expensive fabrication of each device, while polydimethylsiloxane (PMDS), the most common material used for soft lithography fabrication, is not rigid and expands under the pressures required, resulting in poor lysis performance. Here, we demonstrate the fabrication of microfluidic microstructures from off-stoichiometry thiol-ene (OSTE) polymer using soft-lithography replica molding combined with a post-assembly cure for easy bonding. With finite element simulations, we show that the rigid microstructures generate an energy dissipation rate of nearly 107, which is sufficient for continuous-flow cell lysis. Correspondingly, with the OSTE device we achieve lysis of highly deformable MDA-MB-231 breast cancer cells at a rate of 85%, while a comparable PDMS device leads to a lysis rate of only 40%. 相似文献

Women students are one of the fastest growing populations on today's community college campuses and universities. Because of the number of female undergraduates over 25 continues to grow it is important for community colleges to become aware of the various reasons women participate in various stages of their lives. It is imperative that educators address the characteristics of women learners who participate and what programs and/or courses will best meet the needs of the women learners. By recognizing the appropriate programs for adult women students the community college will continue to be the leader of meeting and assisting women in their educational goals. 相似文献
