资产证券化的会计确认方法比较研究

资产证券化为我国融资难问题的解决提供了一种新的方式,被认为是20世纪金融市场中发展最为迅速的金融创新工具。资产证券化作为一种具有复杂结构的交易,这一交易结构的运行,需要法律、税收、会计制度、技术等层面的支持,其中会计制度是一个重要的方面。对资产证券化业务一般形式的会计业务发起人的会计处理理念进行阐述,并对我国资产证券化会计确认问题的相关会计制度进行国际比较和分析,可以为准则的应用和资产证券化在我国的进一步发展提供有益借鉴。     

基于深度学习的跳频信号识别

针对跳频信号分选存在人工提取参数特征具有复杂性的问题,提出了一种基于深度学习的识别方法。首先对跳频信号进行短时傅里叶变换,得到二维的时频矩阵;接着提取信号的轮廓特征,构造三维矩阵作等高线图,并对等高线图进行预处理;最后把预处理后的等高线图输入到卷积神经网络中进行训练、测试,进而实现分类识别。仿真结果表明,在不需要复杂的人工提取参数特征的基础上,在分选率为100〖WT《Times New Roman》〗%〖WTBZ〗时,所提方法经裁剪处理下的信噪比为-15 dB,比支持向量机和传统K-Means聚类算法都低10 dB。实测数据的算法验证表明,所提方法能够将大疆精灵4Pro、hm无人机、司马航模X8HW以及大疆悟2这四类无人机正确分类。

How entrepreneurs recognise entrepreneurial opportunity and its gaps: a cognitive theory perspective

ABSTRACT

Previous studies have verified the relationship between entrepreneurial opportunity recognition and performance. However, the influences of a perceived gap between entrepreneurial opportunities before and after launching a new venture have been neglected. This study applied the partial least square method to analyse the entrepreneurial behaviours and performance of 214 Taiwanese new ventures, and adapted the bootstrap re-sampling method for estimating the variables. The empirical results showed that entrepreneurial resource and entrepreneurial alertness significantly influence the perceived opportunity, while the entrepreneurial resource significantly affects the actual opportunity. The results further demonstrated that both the perceived opportunity and actual opportunity considerably influence new venture performance. This study offered a research framework to better understand the cognition path of entrepreneurial opportunity, and suggested the factors affecting the recognition of perceived opportunity by longitudinal method can be further evaluated. To improve performance, entrepreneurs should enrich entrepreneurial resources and allocate them appropriately, and heighten and maintain their alertness to reduce the perceived gap arising from recognising entrepreneurial opportunities.     

How does face influence the purchase of imitative new products? Moderating roles of product design characteristics

Face plays a profound role in consumption, but the question of how it impacts the purchase of imitative new products remains unanswered in the current literature. Imitative new products, which are legitimate innovations bearing similarities to existing products, are prevalent in many markets. This study investigates how two dimensions of face consciousness—the desire to gain face and the fear of losing face—influence consumers' purchase intentions regarding imitative new products by considering three product design characteristics (new product imitation locus, new product imitation scope, and product hedonism) as boundary conditions. We find through experiments carried out with adult Chinese consumers that the desire to gain face strengthens, but the fear of losing face weakens purchase intention. Moreover, the positive effects of the desire to gain face are weakened by imitation locus (form vs. function imitation) but enhanced by imitation scope (either form or function imitation vs. both form and function imitation); whereas the negative effects of the fear of losing face are strengthened by imitation locus but weakened by imitation scope. Product hedonism enhances the positive effects of the desire to gain face and augments the negative effects of the fear of losing face. This study thus contributes to the face literature by differentiating the roles of two dimensions of face consciousness in affecting consumption of imitative new products. In addition, this study contributes two important constructs—new product imitation locus and new product imitation scope—to the literature on imitative new products.
