In the context of transforming traditional labour-intensive industries into the service economy in China,the reuse of industrial heritage as museums has become a trend,for example,along Shanghai waterfronts,gradually fuelling the continuation of urban memory,reshaping urban cultural identity and promoting the development of the waterfront ***,the connotation of a museum is continually being expanded from an institution to a method,and the major function is gradually shifting from collection to *** studies on Shanghai waterfront industrial heritage have mostly referred to cultural factors,but these factors are still mainly included in macroscale large waterfront projects or microscale single practical project *** typology discussions between the two are ***,this paper examines eleven industrial heritage sites that have been repurposed as museums along Shanghai waterfronts to analyse the urban memory elements of industrial heritage and summarise three classes of memory interpretation strategies:translating memory information,renovating memory carriers,and relating memory ***,the advantages and disadvantages of the study cases are discussed separately,and the following corresponding recommendations are made:1)further enrich and balance memory interpretation strategies;2)enhance the rationality,service,and tolerance of the“exhibition+”mode;and 3)improve local laws and regulations related to the protection and utilisation of industrial heritage to provide references for similar reuse designs.

In this paper, we consider regularity criteria for solutions to the 3D MHD equations with incompressible conditions. By using some classical inequalities, we obtain the regularity of strong solutions to the three-dimensional MHD equations under certain sufficient conditions in terms of one component of the velocity field and the magnetic field respectively.

Neural Regeneration Research 2012年第32期7卷 2542-2547页

Previous studies have reported that individual differences in reappraisal use are associated with partJcular patterns of neural activity. We hypothesized that if ＇high reappraisers＇（individuals who use reappraisal well in a behavioral experiment） completed two training sessions, they would exhibit more reliable patterns of neural activity related to cognitive reappraisal. In the present study, 13 high reappraisers were selected from 27 healthy volunteers through an initial behavioral experiment （first training） followed by a functional MRI experiment （second training）. Emotional images selected from the International Affective Picture System were used for both the behavioral and functional MRI sessions of the experiment. The behavioral results revealed that reappraisal reduced subjective unpleasantness. The functional MRI results revealed that the cognitive reappraisal used by high reappraisers decreased the activation of emotion-responsive regions, including the amygdala, insula, and cingulate gyrus, and increased the activation of regulation-related regions, including the inferior prefrontal cortex, orbital prefrontal cortex, and dorsal medial prefrontal cortex. These findings suggest the involvement of inferior orbital and dorsal medial prefrontal cortex in constructing reappraisal strategies that modulate activity in emotion-processing systems.
