新媒体文化的生存悖论审视

山东社会科学 2010年第10期 31-34页

作者：宫承波中国传媒大学电视与新闻学院北京100024

新媒体文化彰显出前所未有的生机和活力,但其目前的生存也存在着诸多悖论。这些悖论主要体现为:对传统文化拓展与冲击的悖论;自由狂欢与侵权、乱世的悖论;草根性与精英化的悖论;全球化与民族性的悖论。

Correctly locating the tunnel lining cavity is extremely important tunnel quality ***-accuracy imaging results are hard to obtain because conventional one-way wave migration is greatly aff ected by lateral velocity change and inclination limitation and because the diff racted wave cannot be accurately returned to the real spatial position of the lining *** paper presents a tunnel lining cavity imaging method based on the groundpenetrating radar(GPR)reverse-time migration(RTM)*** principle of GPR RTM is described in detail using the electromagnetic wave *** finite-difference timedomain method is employed to calculate the backward extrapolation electromagnetic fi elds,and the zero-time imaging condition based on the exploding-reflector concept is used to obtain the RTM *** this basis,the GPR RTM program is compiled and applied to the simulated and observed GPR data of a typical tunnel lining cavity GPR model and a physical lining cavity *** of RTM and Kirchhoff migration results reveals that the RTM can better converge the diff racted waves of steel bar and cavity to their true position and have higher resolution and better suppress the eff ect of multiple interference and clutter scattering *** addition,comparison of RTM results of diff erent degrees of noise shows that RTM has strong anti-interference ability and can be used for the accurate interpretation of radar profi le in a strong interference environment.

一直到江户时期汉学始终为日本学术的最高境界。但进入明治时代之后,日本将中国看“成落后”的国家,汉学已不再作为达到“先王之道”的学问,随之汉学渐渐地分成几门客观的、科学的学术领域。一批研究中国经典的学者及爱好汉学的作家,虽然一方面对传统中国有憧憬、向往的心情,但另一方面他们一致认为应该用从近代化获得的优势,对中国施加压力,进而改变它。在这一过程中,秉承西方列强,形成了为日本帝国主义获得殖民地提供理论支持的日本式东方学话语。

Objective Lymphedema-Distichiasis(LD, OMIM 153400), a rare autosomal dominant disorder, is mainly characterised by lower limbs lymphedema and distichiasis(referred to as double rows of e yelashes at the rim of the eyelids). Congenial distichiasis is the most conspicuous manifestation o f LD. Affected individuals may also suffer from other ocular complications, including corneal irritati on, recurrent conjunctivitis, photophobia, exotropia, ptosis, congenital ectropion, and congenital c ataracts. According to previous studies, the FOXC2 protein is indispensable for the development of the vascular and lymphatic systems, mutations in FOXC2 could lead to LD. The purpose of the present study was to report the clinical features of a Chinese family with LD, and to screen for no vel genetic mutations in FOXC2. Method A three-generation family from China was recruited in this study. All of the 9 family memb ers underwent complete and comprehensive physical examinations. Among them, 3 members we re diagnosed with LD. Genomic DNA was collected from peripheral blood of all the participants. T he entire coding sequence of FOXC2 was amplified by polymerase chain reaction(PCR), followe d by direct DNA sequencing. We validated the absence of the novel mutation in the normal memb ers of the family and in other 300 ethnically matched normal *** A novel frameshift mutation(c.936 dup CGCCGCC;***313 Argfs X464) in exon 3 of FOX C2 was identified in all the affected family members, but not in the normal family members or the 300 ethnically matched controls. Bioinformatic analysis suggested this frameshift mutation resulte d in premature stop codon thus produced truncated FOXC2 protein. Conclusion FOXC2 protein is characterized by a conserved DNA-binding domain known as the f orehead domain(FHD). This frameshift mutation could lead to truncated FOXC2 protein, which m ay subsequently impair the DNA-binding of FHD, and compromise the transcriptional activation a bility of the
