公共产品理论视野下图书馆产品的生产与供给问题研究

图书馆产品的本质属性是准公共产品。其生产可不以营利为目的，也可以营利为目的；可由政府投资，也可由社会力量投资；可采取公共生产方式，也可采取非公共生产方式；可实行事业型生产，也可实行产业型生产。公共供给、市场供给和混合供给是图书馆产品供给的三种基本方式。混合供给方式较之公共供给方式和市场供给方式有更高的效率。图书馆产品生产与供给有多种组合方式。

The construction of women’s social spaces through physical exercise in urban China

Abstract

By applying feminist geographical theories and qualitative research methods, this article reveals Chinese women’s exercise experiences in urban spaces and discusses how women, through physical activity in neighbourhoods, public places and commercial facilities, constructed social spaces of their own. The findings show that exercise spaces are potentially sites for women’s health, well-being, social networking and collective empowerment. They challenge traditional gendered urban spaces by deconstructing the dual structure of ‘public’ and ‘private’ spheres, inducing women to gradually shift from the ‘edge’ to the ‘centre’. Though the spatial differences in women’s physical activities reflect the diversity and dynamics of women’s spatialities, they also imply the continuous social powers on women in exercise fields, where gendered disparities and class stratification may be sustained.     

Simultaneous changes in seed size,oil content and protein content driven by selection of SWEET homologues during soybean domestication

Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed. Soybean domestication involved parallel increases in seed size and oil content, and a concomitant decrease in protein content. However, science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes. Here, re-sequencing data from >800 genotypes revealed a strong selection during soybean domestication on GmSWEET10a. The selection of GmSWEET10a conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content. The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans. Moreover, GmSWEET10b was found to be functionally redundant with its homologue GmSWEET10a and to be undergoing selection in current breeding, leading the the elite allele GmSWEET10b, a potential target for present-day soybean breeding. Both GmSWEET10a and GmSWEET10b were shown to transport sucrose and hexose, contributing to sugar allocation from seed coat to embryo, which consequently determines oil and protein contents and seed size in soybean. We conclude that past selection of optimal GmSWEET10a alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEET10b may further improve the yield and seed quality of modern soybean cultivars.
