旅游从业者流入动因研究——以阳朔西街为例

旅游就业机会多,门槛较低,包容性较强,劳动者流入现象颇为显著,但旅游从业者流入现象的微观研究还未引起足够重视。利用阳朔西街旅游从业者的抽样调查资料,运用SPSS13.0软件包对其流入动因量表进行因子分析,提取了9个公因子,结果表明:"追求生活方式"是西街旅游从业者最为强烈的流入动因;此外,"地方情结"在劳动者流动决策中起着举足轻重的作用。

Gene Flow from Transgenic Chinese Cabbage (Brassica campestris ssp. chinensis var.utilis) to Related Cruciferae Species Through Outcrossing

It was substantiated by morphological observation, chromosome and DNA identification that the bar gene, conferring the resistance to herbicide basta in transgenic Chinese cabbage ( Brassica campestris ssp. chinensis var. utilis Tsen et Lee), could intrude into the genomes of turnip ( B. campestris ssp. rapifera), heading Chinese cabbage B. campestris ssp. pekinensis) and other non-heading Chinese cabbage ( B. campestris ssp. chinensis in a relatively high frequency while into genome of B. napus at a low frequency via natural cross-pollination in open field. Herbicide resistant hybrids of B. nigra, B. carinata, and B. juncea could be obtained at certain frequency in the greenhouse by hand pollination. At no time did the resistant hybrid plants of transgenic Chinese cabbage with B. oleracea, R. sativus and seven wild weeds, widespread in China, gained in our experiments.
