黄水是浓香型白酒发酵特有的副产物,黄水参数一定程度反映了发酵质量.基于黄水的酸度、还原糖、酒精度等关键参数,采用云模型与改进的D-S(Dempster-Shafer)证据理论,实现对白酒发酵质量的定量评估.基于黄水关键参数建立隶属度云模型,使用云模型判定样本在各发酵质量判定区间的隶属度情况.同时对D-S证据理论的冲突系数计算方式进行改进,使得信息融合结果更具代表性.提出一种浓香型白酒发酵质量的综合评估方法,降低了人工判别的主观性. 相似文献

民事案件证明责任分配不统一的问题引起学术界与司法实务界的关注。与侵权诉讼中的证明责任分配相比,合同纠纷案件的证明责任分配的争议不大。但是对同一案件或同一类案件的证明责任分配,合议庭每个成员或一审和二审或各个法院的判决持己见已经屡见不鲜。尤其是看似简单的借贷合同等案件的证明责任分配意见很难统一。运用具体诉讼具体分析、参考国外先进诉讼制度的方法探究与论证:合同案件中,客观证明责任分配不是考虑分配给原告还是被告,而是以诉讼请求为单位,在债权人和债务人之间分配的。通过验证:以上证明责任分配基准通用于各类合同案件。 相似文献

ABSTRACTProcess-tracing (PT) as a distinct case-study methodology involves tracing causal mechanisms that link causes (X) with their effects (i.e. outcomes) (Y). We trace causal mechanisms whereby a cause (or set of causes) produces an outcome to both: (1) make stronger evidence-based inferences about causal relationships because the analysis produces within-case evidence of each step of the causal process (or absence thereof) in between a cause and outcome, and (2) because tracing mechanisms gives us a better understanding of how a cause produces an outcome. Yet, when we look at the methodological literature on PT, there is considerable ambiguity and discord about what causal mechanisms actually are. The result of this ambiguity and discord about what mechanisms are clearly maps onto existing applications of PT, with most PT case studies completely ignoring the underlying theoretical causal processes. In the few PT applications where mechanisms are unpacked, they are typically only developed in a very cursory fashion, with the result that there is considerable ambiguity about what theoretical process the ensuing case study actually is tracing. If we want to claim we are tracing causal mechanisms, the causal processes in between X and Y need to be unpacked theoretically. How can we claim we are tracing a causal ’process’ when we are not told what the process (i.e. mechanism) actually is? To alleviate this problem, the article attempts to develop a clearer definition of causal mechanisms to provide scholars with a framework for theorising mechanisms in a fashion that is amenable to in-depth empirical analysis using PT. 相似文献

Using a large sample of firms listed on the Korea Stock Exchange, this paper evaluates the usefulness of a structured, programmable financial statement analysis for investment decisions. In doing so, we develop a firm valuation model which links a firm's market value with fundamental variables such as the ability of a firm to generate cash flows, growth potentials, and risk. We predict a firm's intrinsic value directly from an extensive set of financial statement variables which proxy for the theoretical variables implied by the model. We then construct a series of trading strategies with zero net investment (called D-strategies) on the basis of D-values which measure percentage differences between predicted intrinsic values and observed market values. We observe that the market-adjusted and size-adjusted (hedge-portfolio) returns to the most conservative D-strategy turn out to be in the order of 16.92% and 11.44%, respectively,for the 12-month holding period. When our sample is stratified into two sub-samples based on firm size, the D-strategy yields higher excess return for the small-firm sub-sample than for the large-firm sub-sample. The above evidence, taken as a whole, strongly indicates that one can construct a profitable trading strategy by directly predicting intrinsic values through a structured financial statement analysis such as ours. 相似文献

How could one transform structural econometrics with a view to deliver empirical models that generate reliable inferences and trustworthy evidence for or against theories or claims, as well as provide trustable guidance for economic policy makers? Nell and Errouaki, in Rational Econometric Man: Transforming Structural Econometrics, put forward their proposal on how to achieve that, by discussing the effectiveness of alternative proposals in the literature. There is a lot to agree with in this book, but the primary aim of this note is to initiate the dialogue on issues where opinions differ on how to transform structural econometrics. The discussion focuses on what I consider a crucial aspect of empirical modeling—statistical adequacy—but the authors question its practical usefulness for empirical modeling. I will attempt to make a case that ‘methodological institutionalism’ cannot be properly implemented without employing the notion of statistical adequacy. 相似文献
