城市雨水资源化--以太原市为例

太原市在缺水城市中具有一定代表性。该市地下水超采严重。未施行分质供水,水价偏低,浪费严重。认为仅靠节水不能解决根本问题。充分利用雨水资源才能取得很好的经济,生态和社会效益。该市年内降水集中,其中60%被无效蒸发,若发展1000km2集雨面积,则可解决全市1年的工业用水,建议加大投入。强化工程配套,鼓励用水大户自建集雨工程,回灌废弃的中浅井,增加雨水的入渗。     

Women farmers’ participation in the agricultural research process: implications for agricultural sustainability in Ethiopia

Empowering women farmers to participate in agricultural research is a key strategy for sustainable agricultural development. Women empowerment has the potential to improve their roles in agricultural production while enhancing nutrition and food security. Although new agricultural development policies are focusing on improving women engagement in agriculture, there is limited literature on women empowerment in relation to agricultural research. This study used mixed methods to analyse women farmers’ participation in four stages of the agricultural research process – design, testing, dissemination, monitoring and evaluation. Two hundred and thirty individual interviews with women farmers and 16 focus group discussions with men and women farmers were conducted in four Woredas (districts) of Ethiopia. Quantitative data were analysed using binary and multivariate probit models. Qualitative data were analysed using line-by-line coding. The results showed that several empowerment indicator variables significantly (p?≤?.001) influenced women’s participation in different stages of agricultural research. Specifically, input in production decisions, autonomy in plot management, membership to farmer groups, and ability to speak in public enhanced women’s participation in different stages, in addition to access to information and extension services, education and land size. Cultural norms hindered women’s empowerment and engagement in research. To foster sustainable agriculture development, it’s important to integrate holistic and proactive gender perspectives into research strategies to increase women’s participation in farmer research groups, access information and knowledge, have voice and challenge constraining cultural norms and traditions.

Seeking knowledge or gaining legitimacy? Role of social networks on new practice adoption by OEM suppliers

This study tests two competing views (namely, institutional theory and organizational learning theory) regarding the role of social networks on firms' new practice adoption from 1999 to 2008 in Taiwanese high-tech sector firms that operate under the Original Equipment Manufacturer (OEM) supplier model. Empirical data analysis shows that the sampled suppliers adopt customer relationship management (CRM) systems mostly to gain legitimacy, while they adopt supply chain management (SCM) systems with joint desires of gaining legitimacy and seeking knowledge in the OEM network. The findings indicate that social networks provide firms with a dedicated mechanism for assessing the logic of adopting new practices.     

Do the magnitude and asymmetry of specific asset investments matter in the supplier–buyer relationship?

Abstract

Despite a body of literature on specific asset investments, the extant literature falls short of exploring the magnitude and symmetry of specific asset investments in supplier–buyer relationships. This paper builds on prior research to identify and examine the impact of total and asymmetric specific asset investments on commitment, trust, and conflict in supplier–buyer relationships. Covariance structure analysis is used to analyse survey data. The results show that total SAI are positively related to commitment and trust, while asymmetric SAI are negatively related to trust and positively related to conflict in supplier–buyer relationships. Decision-making uncertainty affects trust, commitment, and conflict more than any other variables. Therefore, firms should work to strengthen their relationships by increasing the magnitude of specific asset investments with the aim of increasing trust and commitment. We also discuss the limitations of this study and suggestions for future research.
