普碳钢超大总压下量可逆冷轧工艺技术及生产实践

针对目前我国部分钢企由于现有工艺装备投产较早、技术落后、机组能力不足，只能采取中间退火+二轧程工艺生产0.12～0.15 mm薄规格冷轧产品，生产成本增加、周转周期长，不能灵活应对复杂多变的冷轧市场需求的状况，开发了普碳钢单轧程可以实现95%以上超大总压下量的单机架六辊可逆冷轧机组。结合国内新投产的某1 150 mm单机架六辊可逆冷轧机组的稳定规模化生产实践，阐述了机组工艺设备选型、主要工艺技术参数配置和生产需解决的核心关键技术难点，同时列举了几种市场需求量大、附加值高的薄规格冷轧产品的现场实际生产工艺参数，以说明该机组的实际应用效果。

大凌河流域初始水权分配实践评价

结合大凌河流域初始水权分配实践,从分配范围、分配机制、分配原则、分配模型等方面,对现有研究成果进行全面梳理。在此基础上,结合大凌河流域特点,借鉴我国流域水资源配置评价指标体系,从公平性、效率性、可持续发展、政府宏观调控4个维度,设计了一套水权分配评价指标体系,进而构建了初始水权分配实践效果的耦合评价模型,并应用于大凌河流域。结果表明,在政府和大凌河流域水行政管理部门的宏观调控作用下,通过加强大凌河流域所在区域的政治民主协商,流域内各区域水权分配结果充分体现了与其社会经济发展之间的匹配性,且各区域之间的耦合协同发展效度均达到较高水平。     

Structuration bridging diffusion of innovations and gender relations theories: a case of paradigmatic pluralism in IS research

This paper discusses the adoption of a pluralist theoretical framework – one that is also multiparadigmatic – for conducting and publishing information system (IS) research. The discussion is illustrated by a single case study involving the Australian cotton industry. The theoretical framework is informed by three sociological theories, each with its particular paradigmatic assumptions: structuration theory as a meta‐theory, and diffusion of innovations and gender relations as lower‐level theories from notionally opposing paradigms. Theoretical pluralism helped to produce rich findings, illuminating both the social nature of women farmers' roles, the materiality of the cotton farming context, the characteristics of the decision support systems in use and the recursive way in which human agency and institutional pressures shape each other. Because users of so‐called divergent paradigms often face criticism based on the incommensurability issue, one of the main contributions of this paper is to discuss the value of a pluralist and multiparadigmatic theoretical framework in dealing with complex IS social phenomena.     

A comprehensive approach to evaluating watershed models for predicting river flow regimes critical to downstream ecosystem services

Selection of strategies that help reduce riverine inputs requires numerical models that accurately quantify hydrologic processes. While numerous models exist, information on how to evaluate and select the most robust models is limited. Toward this end, we developed a comprehensive approach that helps evaluate watershed models in their ability to simulate flow regimes critical to downstream ecosystem services. We demonstrated the method using the Soil and Water Assessment Tool (SWAT), the Hydrological Simulation Program–FORTRAN (HSPF) model, and Distributed Large Basin Runoff Model (DLBRM) applied to the Maumee River Basin (USA). The approach helped in identifying that each model simulated flows within acceptable ranges. However, each was limited in its ability to simulate flows triggered by extreme weather events, owing to algorithms not being optimized for such events and mismatched physiographic watershed conditions. Ultimately, we found HSPF to best predict river flow, whereas SWAT offered the most flexibility for evaluating agricultural management practices.
