基于模糊影响图评价算法的创业企业价值评估方法

由于创业企业具有成长性强、历史数据少、财务数据不够可靠等特性,依赖于企业历史数据的一般企业价值评估算法对创业企业来说并不适用。因此,结合创业企业的特点,对创业企业价值评估所涉及的指标进行整理与筛选,之后应用模糊影响图算法构建适合创业企业的价值评估模型,并对模型的应用作出说明。

Demystifying blockchain: A critical analysis of challenges,applications and opportunities

The blockchain is considered to be the potential driver of the digital economy. The Blockchain technology outweighs the challenges associated with the traditional transaction business governed and regulated by the third trusted party. There is a growth in the interest among the researchers, the industry, and the academia to study and leverage the potential of Blockchain. Blockchain provides a decentralized and distributed public ledger for all the participating parties. Though it seems that blockchain is a viable choice and solution for all the centralized governed and regulated transactions (in digital online space), it has potential challenges that need to be resolved; opportunities to be explored, and applications to be studied. This paper utilizes a systematic literature review to study several research endeavors made in the domain of blockchain. To further research on blockchain adoption, the paper theoretically constructs an integrated framework of the blockchain innovation adoption process in an organization considering organizational and user acceptance perspectives. This would facilitate its widespread adoption, thereby achieving sustained leadership solutions. The paper offers 23 propositions to information systems (IS)/information management (IM) scholars with respect to innovation characteristics, organizational characteristics, environmental characteristics, and user acceptance characteristics. Further, the paper explores several areas of future research and directions that can provide deep insights for overcoming challenges and for the adoption of blockchain technology.     

Business models shifts: Impact of Covid-19

No amount of crystal ball gazing may help us fathom the full impact of the Covid-19 (C-19) crisis on business organizations in a distinct manner. Given the lack of precedence, any such analyses seem to demand routine revisions as we progress further up the “number of infected” curve. Most countries of the world have imposed restrictions on social congregations or even people working in close proximity to each other. Industries that produce and deliver information products and services therefore, have continued to function while those that manufacture physical products especially labor-intensive firms were forced to minimize operations or temporarily shut down. However, in most countries, physical products which were essential in nature were reluctantly permitted to be manufactured given the need for them in people’s everyday life. In this viewpoint, I draw upon three dimensions – information intensity of product/service, information intensity of process/value chain; along with a third dimension – essential nature of the product/service to help understand the immediate implications of C-19. I also present some anecdotal evidences of attempts to alter business models in these circumstances in order to address the challenges that certain product characteristics impose but at the same capitalize on the business opportunities presented by the essentiality of the products.     

企业孵化器发展的国际比较研究

企业孵化器的概念自20世纪80年代引入中国,逐渐成为中国高新技术产业化支撑服务体系的重要组成部分.但是从总体上讲,中国企业孵化器还没有形成良好的运行机制及管理规范,制约了孵化器作用的进一步发挥.通过对欧美国家及以色列企业孵化器发展的比较研究,揭示其企业孵化器成功发展的经验,为中国企业孵化器进一步发展提供借鉴.     

基于FPGA的DDS实现的几种方式

直接数字频率合成器(DDS)采用的是一种新的频率合成技术,它具有频率分辨率高、频率转换快、相位噪声小等一系列优点。本文根据DDS的基本原理,提出了基于FPGA的DDS设计与实现。利用Quartus II、MATLAB/Simulink、DSP Builder等功能强大的开发工具,分别从不同的角度给出了几种基于FPGA的DDS的实现方式。最后,就这几种实现DDS的方式,对其优缺点进行讨论。

森林生态系统服务流量过程研究

生态系统服务研究是生态学和生态经济学研究的热点和前沿,但迄今为止对生态系统服务流量过程的研究在世界范围内仍处于薄弱环节。本文以千烟洲中亚热带人工林生态系统为例,以2005年-2007年3年的定位监测数据为基础,研究了4类典型生态系统服务的流量过程。研究表明,千烟洲森林生态系统的年均生物量生产、气体调节、水源涵养和土壤保持服务价值的范围分别为（497.48±33.66） 元/（hm²·a）、（2189.21±247.18） 元/（hm²·a）、（1432.40±454.32）元/（hm²·a）和（224.55±8.82）元/(hm²·a)。4类典型生态系统服务流量均表现出显著的季节变化,生物量生产、气体调节和水源涵养服务表现为连续性实现,而土壤保持服务为离散型实现。年内某些日,森林生态系统产生负的气体调节和水源涵养流量。就各月平均流量而言,水源涵养和土壤保持服务的最大流量发生在6月份,分别为274.74 元/（hm²·month）和47.89元/（hm²·month）,生物量生产的最大流量出现在8月,为65.19元/（hm²·month）,最大的气体调节服务流量出现在7月,为303.67元/（hm²·month）。对于生物量生产、气体调节、水源涵养和土壤保持服务,夏季产生的相应服务价值分别占38.11%、37.15%,25.67%和42.53%。本研究有助于增进对生态系统服务形成机理与强度的认知,同时能为生态系统服务的保育提供依据。     

Business schools,the anxiety of finance,and the order of the ‘middle tier’

Financial imagination plays a fundamental, yet ambivalent role in the establishment of hierarchies within and between business schools, and in business life at large. This study examines this process in the ‘middle tier’ of business education: that is, in the social space in which students and instructors understand themselves to occupy a ‘mid-range’ position within an order of excellence and success. Largely articulated through business school rankings, this order strongly relies on the centrality of the financial curriculum, proficiency in which is understood as both a proxy for smartness and a sign of moneymaking capacity. In the ‘middle tier’, this order manifests in the form of an anxiety: an order that, though legitimate, is thought not to be attained, or hardly attainable. The study draws from ethnographic investigation in a ‘middle tier’ business school with attention to how finance is made sense of in relation to an alternative curriculum, and in connection with the aim of ‘making it to the top’. A comparison with a ‘top tier’ business school allows furthering understanding of how the order of business schools relies on the anxiety of finance in order to reproduce an acquiescence to dominant financial imagination.     

Managing Disagreement while Managing not to Disagree: Polite Disagreement in Negotiation Discourse

This paper explores the exercise of politeness by Malays in business negotiations with Japanese. The study looks at how disagreement is realized linguistically. Its linguistic configurations in the form of speech acts and discourse strategies and their underlying politeness strategies are identified and described. The study also reports on how Malay cultural values are reflected in the language use. The implications of the study for negotiation in general and the expression of disagreement in particular are then discussed. The findings are significant for an understanding of disagreement by Malays, particularly when interacting in English. Additionally it provides insights into how Malay cultural values impinge on Malay interaction styles vis-à-vis styles of disagreement. The findings work towards an understanding of how Malay values are manifested in the discourse of disagreement in oral communication.
