Risks Matrixes Risks Assessment Tools of Small and Medium-Sized Enterprises： The Case of Latvia

The enterprises need to assess the risk dynamic of financial instability and its impact on small and medium-sized enterprises＇ development, because it is important for enterprises to extend commercial activity and to open a new structural subdivision. We have researched types of risks, their identification, classification, and assessment possibilities in activities of small and medium-sized enterprises. We have used our own algorithm of identification, classification, and assessment of enterprises＇ risks. The goal of this research is to study the economic and financial risks＇ impact on small and medium-sized enterprises＇ development in Latvia. For study purpose, we have carried out the questionnaire of representative small and medium-sized enterprises about the economic and financial risks＇ impact on enterprises＇ development in Latvia. We have created classification of Latvian services sectors＇ economic and financial risks in the period from 2011 to 2012. Those risks have been included in the questionnaire. The risks matrix is a quantitative assessment tool of risks. We have created Latvian service sector economic and financial risks matrix. We have arranged risks by their sizes of possible losses for enterprises. For each risk has been assessed its probability of realization. We have created Latvian accommodations （hotel） and food services technological process risks map. Several parts of the risk map （segments） make it possible to assess each type of the risk separately in its segment. Risks matrix can be used to choose enterprises＇ strategy of risk management. Enterprise＇s strategy of risk management is developed by analysing zones of risk level.     

信息固有价值与其新闻价值内在关系的研究

文章从信息流入公众的途径以及根据接受到的信息溯源媒体形式,从正反两方面探讨信息的本身固有价值与其新闻价值的内在关系。文章建立了"影响力函数"并利用改进了"贝叶斯模型",两模型相结合,再根据信息的固有价值、信息的传播途径、信息的传播速度以及公众兴趣这几个影响因子将数以万计的信息分类,最终筛选出可被当作新闻报道的有新闻价值的信息。     

马尔科夫链在股票价格预测中的应用

论文首先对马尔科夫链模型的数学原理进行了概述,然后在当前股票市场的背景下,应用马尔科夫链模型对沪深300指数的波动进行了预测,通过马尔科夫的平稳分布和最终的稳态条件,计算出股指下跌、持平、上涨三个状态的概率分布,为马尔科夫模型应用的拓广和股票价格的概率估计预测提供理论依据和实际应用的参考。     

从财政风险矩阵看公办高校债务风险化解

高校扩招政策的实施,对我国高等教育的发展起了巨大推动作用,实现了中国高等教育从精英教育到大众化教育的过渡。但高校扩招也带来了一系列问题,教学用房和学生宿舍紧张、教学仪器设备落后、图书资料陈旧短缺等现象,已影响到了学校教学质量的提高和可持续发展。为解决这一问题,在财政拨款和学校自筹资金有限的情况下,向银行贷款来解决基本建设中资金不足的问题已成为各公办高校的通行做法。但过度负债反过来又阻碍了公办高校又好又快发展,形成了极大的财务风险。因此,如何化解和防范公办高校债务风险,已成为摆在理论界和高校财务管理部门面前一个亟待研究解决的问题。     

基于主客观组合群决策的权重区间确定方法

提出了一种确定权重区间的方法,即将由多位专家确定的主观权重和用多种方法计算的客观权重相结合,形成权重区间,通过分析主客观权重区间的重合关系,计算权重区间的置信度和精确度,据此对权重区间进行循环优化。最后用算例表明了该方法的科学性和可操作性。

Countermeasures of adaptation to climate change： establishment and application for implementation matrix

In the conceptual framework of adaptation policy assessment to climate change, adaptation measures can be categorized as two groups：facilitation and implementation. Facilitation measures refers to activities that enhance adaptive capacity, while implementation refers to activities that actually avoid adverse climate impacts on a system by reducing its exposure or sensitivity to climatic hazards, or by moderating relevant non-climatic factors. This paper aims to establish a matrix of implementation measures of adaptation to climate change, through four different ways how adaptation can influencc the relevant elements of climate change. reducing the exposure, reducing the sensitivity, alleviating the adverse impacts and reducing the negative non-climatic factors, and then further discuss the particular implementation measures of adaptation to climate change, through application studies on the selected sub-systems, intend to organize the disordered implementation measures in existent, and put forward some new measures under the guidance of this matrix, which could enrich and promote the system and content of implementation measures of adaptation.     

城市表层土壤重金属污染分析

城市重金属元素已越来越成为人们关注的焦点本文就城市表层土壤重金属污染分析建立了相应的数学模型，采用单项污染指数与综合污染指数评价方法分析了五个区域的重金属的污染程度，及其传播特征，最后确定了污染源的位置本文对模型进行综合，为使模型更符合实际情况，我们对数据进行补充，重新建立了双权重因子的模糊数学模型。
