Assessing the Risk of Secondary Transfer Via Fingerprint Brush Contamination Using Enhanced Sensitivity DNA Analysis Methods

Experiments were performed to determine the extent of cross‐contamination of DNA resulting from secondary transfer due to fingerprint brushes used on multiple items of evidence. Analysis of both standard and low copy number (LCN) STR was performed. Two different procedures were used to enhance sensitivity, post‐PCR cleanup and increased cycle number. Under standard STR typing procedures, some additional alleles were produced that were not present in the controls or blanks; however, there was insufficient data to include the contaminant donor as a contributor. Inclusion of the contaminant donor did occur for one sample using post‐PCR cleanup. Detection of the contaminant donor occurred for every replicate of the 31 cycle amplifications; however, using LCN interpretation recommendations for consensus profiles, only one sample would include the contaminant donor. Our results indicate that detection of secondary transfer of DNA can occur through fingerprint brush contamination and is enhanced using LCN‐DNA methods.     

毛笔书法作品的著作权保护——以《刑法修正案(八)》为视角

毛笔书法是中华文化宝库中的瑰宝。当前,随着国家对发展文化事业的不断重视,中华文化也在不断的复兴和崛起,并一天天的走向国际化。因此,为了方便国际间的文化保护和交流,我国近些年对著作权法及其实施条例做了多次修订。可见,我国对于文化产业的保护也在不断的加强。因此,在这样的时代背景下,对于传统文化著作权保护的研究就显得尤为重要。笔者旨在结合毛笔书法的艺术特性和我国著作权法的相关规定,对其著作权保护的理论进行初步研究。

Lost Childhood

正EVERY school day Dongdong wakes up at 6:20.Still half asleep,his mother has to force him to drag on his clothes and brush his teeth.Within 15 minutes he has to be in the car,ready to leave,which means his breakfast has to be consumed on the way.If it is winter,the sun has not yet risen.
