职业院校产教融合质量评价是以职业院校产教融合行为作为对象,依据一定的评价原则与标准,以满足利益相关方要求为目的开展的系统性价值判断。CIPP评价作为一种全过程评价,与职业院校产教融合质量评价思路高度吻合。有必要以CIPP模式作为框架,借助SPSS和AMOS等分析工具,构建职业院校产教融合质量评价指标,同时,以层次分析法(AHP)确立评价指标权重,最终形成基于CIPP模式的职业院校产教融合质量评价指标体系。

目的完整、系统介绍断点回归设计(RDD)原理及统计方法,为其在公共卫生领域应用提供参考。方法在介绍断点回归设计原理基础上,用室内甲醛干预的实例演示了利用Stata软件实现断点回归统计方法的过程,介绍和比较属于参数法的多项式回归和属于非参数法的局部线性回归的分析方法和结果。结果RDD是一种准实验设计,对研究对象没有随机分组,而是选择一个与干预措施有关的变量,根据该变量的取值选择切点划分干预组和对照组。RDD在内部有效性方面优于其他准实验设计,但外部有效性受到一定限制。基于观察性资料的RDD不仅可控制可观测的混杂因素,还可控制无法观测的混杂因素,也更符合伦理道德。在本文实例中,多项式回归和局部线性回归两种分析方法的结果基本一致。结论RDD在公共卫生领域的真实世界研究中有广阔的应用前景,为科学评估干预政策和提供高质量决策依据提供新的思路和方法。

Soil microbes play essential roles in the biogeochemical processes of organic carbon and nutrient cycling. Many studies have reported various short-term effects of fertilization on soil microbes. However, less is known about the effects of longterm fertilization regimes on the rhizosphere. Therefore, the objective of this study was to explore how the soil microbial communities in the rhizosphere respond to different long-term fertilization strategies. Based on a 21-year field treatment experiment in Guizhou, China, we extracted phospholipid fatty acids(PLFAs) to determine the microbial community structure in both the non-rhizosphere(NR) and rhizosphere(R). Six treatments were included: no fertilizer(CK), mineral nitrogen fertilizer(N), N with potassium(NK), phosphorus with K(PK), NPK, and NPK combined with manure(MNPK). The results showed that total PLFAs under unbalanced mineral fertilization(N, NK and PK) were decreased by 45% on average in the NR compared with CK, whereas MNPK increased fungi and G~– bacteria abundance significantly in both the NR(by 33 and 23%) and R(by 15 and 20%), respectively. In addition, all microbial groups in the R under these treatments(N, NK and PK) were significantly increased relative to those in the NR, except for the ratio of F/B and G^+/G~–, which might be due to the high nutrient availability in the R. Soil pH and SOC significantly regulated the soil microbial community and structure, explaining 51 and 20% of the variation in the NR, respectively. However, the rhizosphere microbial community structure was only significantly affected by soil pH(31%). We concluded that the soil microbial community in the NR was more strongly affected by long-term fertilization than that in the R due to the rhizosphere effect in the agricultural ecosystem. Rhizosphere nutrient conditions and buffering capacity could help microbial communities resist the change from the long-term fertilization.

Trivium is an international standard of lightweight stream ciphers(ISO/IEC 29192-3:2012).In this paper,the Trivium-like NFSRs,a class of Galois NFSRs generalized from the Galois NFSR of Trivium,are studied from the perspective of Fibonacci *** is shown that an n-stage Trivium-like NFSR cannot be equivalent to an n-stage Fibonacci NFSR,which is proved by showing the existence of“collision initial states”.As an intermediate conclusion,a necessary and sufficient condition for a kind of linear degeneracy of a Trivium-like NFSR is obtained from the persepective of interleaved ***,the smallest stage number of a Fibonacci NFSR that can generate all the output sequences of an n-stage Trivium-like NFSR is shown to be greater than n-7 and this value is no less than 371=287+min{93,84,111}specifically for the 288-stage Galois NFSR used in *** results contradict the existence of a equivalent Fibonacci model of Trivium NFSR of small stage,which implies that Trivium algorithm possesses a fair degree of immunity against“structure attack”.
