根据低聚糖、明列子、魔芋等原料的特点,在孝感老字号米酒的基础之上,采用相应的工艺处理过程,生产孝感保健型系列米酒,有很高的药用价值和社会经济效益。其关键控制点:选用孝感传统优质米酒曲;浸泡水温25~30℃,时间6~8小时,米吸水量45%~50%;蒸煮压力0.08~0.2Mpa,时间10~20m in;发酵环境温度25~28℃;保健材料与米酒的调配应掌握温度,比例与PH值,温度控制在40~50℃,搅拌转速在20 r/m in以下;杀菌温度95~100℃,时间在30m in以内。 相似文献

The relationship between research and policymaking has been discussed repeatedly. However, the debate tends to be in general, abstract terms or from a macroeconomic perspective with any examples described in a fairly cursory way. Despite the inherent complexity of the research-policy interface, analyses tend to homogenise ‘research’ and ‘policy’ as coherent entities with discussions often focusing on products (research and policies) rather than on the relationships between producers (researchers and policymakers). Here, we take one piece of research on qualifications that has influenced policy rhetoric over the last 5 years. We trace the career of the research from its production in the late 1990s in order to understand the conditions of its dormancy, re-emergence and use over the ensuing years. The paper serves to document the case, which is important in its own right, but also proposes a typology of ways in which research gets adopted and adapted into policy. 相似文献

环境犯罪严重而刑罚少,环境犯罪构成要件难以确定是关键因素。而国内对其研究者颇少,对环境犯罪构成要件的界定探讨可以为立法司法实践与理论研究提供材料。为此,首先明确其概念,确定界定的原则依据,然后对环境犯罪构成要件三方面内容及其层次、排列顺序进行论证,最后分析了环境犯罪构成要件应该包括的要素,通过国内外对比分析,突破传统犯罪四要件说,确立了环境犯罪构成要件三要素说。 相似文献

There is an increasing emphasis on the importance of social competence for children's development, well-being, and learning. Thus age- and context-appropriate measures are needed. This study addresses the structural validity of the Lamer Social Competence in Preschool (LSCIP) scale, developed to accommodate the Nordic model of early childhood pedagogy. The authors specify the theoretical basis for a bi-factor model of social competence. This model is tested in a large (n?=?1157), community based sample of Norwegian children, including teacher- (at age 2, 3, and 4), mother- (at age 4), and father- (at age 3) reports. A model with a main factor for social competence, and three bi-factors fit data across ages and reporters, with factorial, but not strong, invariance over time. 相似文献

Moving beyond academic achievement goal measures: A study of social achievement goals 总被引:1,自引:0,他引:1
S. Jeanne Horst Sara J. Finney Kenneth E. Barron 《Contemporary educational psychology》2007,32(4):667-698
The current research explored the theory of social goal orientation. More specifically, we conducted three studies utilizing six-independent university student samples to evaluate the construct validity of the Social Achievement Goal Orientation Scale (SAGOS; Ryan & Hopkins, 2003), a measure representing the construct of social goal orientation. The purpose of Study 1 was to: (1) compare the three-dimensional (mastery, performance-approach, and performance-avoidance) model of social goal orientation to three theoretically based competing models, (2) examine item functioning, and (3) assess generalizability of the factor structure. The fit of the proposed three-factor model was promising; however, areas of misfit and problematic items were identified. Stronger support for the three-factor structure of goal orientation was found using scores from an abbreviated 13-item SAGOS. In Study 2, item wording was altered slightly to evaluate a revised Social Achievement Goal Scale (SAGS), yet resulted in similar findings. Study 3 examined external validity evidence for the SAGS, garnering some support for the meaning of the scores. Although continued refinement of the SAGOS and SAGS is recommended, the findings help contribute to our general understanding and conceptualization of social goal theory and the role that social goals may play in academic contexts. 相似文献
