从羊草的螺旋扩张策略看企业的生存与发展

通过对羊草的生长过程观察,发现其生存策略为:巩固策略、扩张策略、占领策略、克隆区隔避险策略、有性繁殖避险策略,二八战术,建立了羊草螺旋扩张规律图。类比分析表明,严格按照羊草生存发展策略运行的企业,如海尔集团,阿里巴巴网络公司等都遵循螺旋扩张战略而得到了发展壮大;宝洁集团由于违背了克隆区隔避险策略造成了产品市场占有率的急剧下降,百年老企业王麻子盲目进行品牌延伸(盲目扩张),削弱消费者对"王麻子"品牌的忠诚维系,导致了最后以破产收场;曾经辉煌的巨人集团只进行扩展和占领,没有有效实施巩固和避险策略,造成企业分崩瓦解;因此羊草螺旋扩张战略对企业的生存和发展相关问题具有积极长远的指导意义。     

Accidental injuries among the elderly within the Vienna community: Epidemiology,risk factors and preventive measures

Abstract

Unintentional injuries ('accidents’) among elderly people are a significant burden in public health because such accidents happen frequently and because the proportion of older age groups in the population will continue to rise during the coming decades. One aim of this study, which was done in Vienna, the capital of Austria, was to broaden the preventive concept, adding lifestyle and living conditions to already well-known risk factors following the health promotion approach. Furthermore, characteristics that predispose older residents to accidents should be identified in order to design preventive measures for reducing injuries in this age group.

809 interviews with people 60 years of age and over were conducted, concerning accidents, outcomes of accidents, physical fitness, drug intake, type of house or dwelling, equipment in the household incorporating safety features, psychological well-being and social relations. The information collected was used to draw cross-sectional comparisons between participants who reported having experienced at least one accident in the previous 12 months and those who did not. Furthermore, the accident incidents were classified into 2 groups: incidents without injuries and injurious accidents. The latter served as a base for the epidemiology of injuries for people 60 years of age and over within the Vienna community.

20% of all senior citizens suffer at least one unintentional injury every year, in addition to which 8% experience critical incidents (mostly falls) without injury. Most accidents occur at home or involve pedestrians in public traffic areas. Over 90% of all accidents are falls, and 20% result in fractures. The most important risk factors for accidents in the elderly are gender, increasing age, poor physical fitness and low physical activity, the type of household and household equipment, poor psychological well-being, low income and loneliness.

The findings regarding falls suggest some possible opportunities for reducing the risk of falls by improving buildings and dwellings of the elderly. A promising attempt at practical implementation of these findings is being conducted by the Vienna-based Austrian Institute for Home and Leisure Safety in cooperation with the Vienna City Council. These two organizations are implementing a long-term program that aims at mobilizing institutions and organizations involved in working with the elderly.     

Risk reporting quality: implications of academic research for financial reporting policy

In this paper, I survey empirical research on the relevance of firms’ financial report information for the evaluation of their risk. I recommend that financial reporting policymakers require or encourage firms to enhance their risk reporting quality in four ways. First, firms should report comprehensive income statements that: (1) use fair value or a similarly information-rich accounting measurement attribute and (2) separate the components of comprehensive income that are primarily driven by variation in cash flows from those that are primarily driven by variation in costs of capital. Such comprehensive income statements would provide users of financial reports with the flexibility to calculate alternative summary accounting numbers and to perform different types of risk assessment analyses. Second, firms should conduct and disclose the results of back-tests of prior significant accrual estimates, indicating any identified trends in and drivers of revisions to those estimates, and describing the effects of those revisions on current or future summary accounting numbers. Third, firms should aggregate and present risk disclosures in tabular or other well-structured formats that promote the usability of the information. Identifying existing best disclosure practices and encouraging new best practices are the most natural way to do this. Fourth, for model-dependent risk disclosures, firms should disclose the primary historical and forward-looking attributes of the models and their implementation in practice, sensitivity of the model outputs, and benchmarking of the models to standard portfolios of exposures.

金融资产规模、公允价值会计 与管理层过度自信

本文以2004-2009年持有证券资产的A股上市公司为样本，对金融资产规模的决定因素进行了理论和实证研究，得到以下研究结论：（1）公允价值会计是上市公司金融资产规模显著增加的解释因素；（2）管理层过度自信在成本计量模式下与金融资产规模只有弱相关性，但在公允价值会计下却与金融资产规模显著正相关；（3）受政府控制的公司、大股东持股比例高的公司在成本计量模式下有显著更低的金融资产规模，但在公允价值会计下，特别是当管理层过度自信时，金融资产规模却呈现为显著增加。上述结论解释了会计理念、管理层行为与金融风险的内在关联性：公允价值计量模式遵循的是价值相关性原则，要求把证券持有利得也计入资产价值和会计收益，这个未来价值理念激励了公司管理层和控股股东的金融投资行为。     

Risk management strategies - before Hominization and after

Selected examples, ranging from birds to pastoralistic nomads and subsisting peasants, indicate that the higher animals adopt foraging strategies similar to individual decision makers in economies without market (subsistence economies): in contrast to actors in (ideal neoclassical) market economies, maximizing expected utility, they operate in such way as to optimize long-term survival of genetically related groups. This can be seen as a strategy of (maximum) ruin avoidance, played by 'selfish genes'. In the sense of conjectural history the parallelism between risk behaviour of animals and early men may be regarded as the continued existence of principles of natural evolution beyond hominization up to the historical emergence of complex societies where pursuit of surplus production replaced ruin avoidance as the primary orientation in the older subsistence economies.     

我国中小商业银行的操作风险问题研究

商业银行作为经营金融资产和负债的机构,风险也随之诞生。近年来,作为商业银行风险之一的操作风险在银行业金融机构日常的经营业务过程中所造成的损失日益严重,越来越受到银行业金融机构与有关监管部门的重视。在现代竞争激烈的社会,降低操作风险造成的损失也就是间接地提高金融机构的竞争力,提升金融机构的服务质量。中小银行发展初期注重业务的快速发展,操作风险管理起步较晚,操作风险管理水平较低,操作风险管理体系仍需不断完善。     

Incorporating sustainability criteria into credit risk management

Does a commercial debtor's economic, environmental and social performance in terms of sustainability affect its credit risk rating? Does adding criteria aimed at assessing a lender's environmental, social or sustainability practices provide added value to traditional financial rating criteria? Many analyses have reported that a correlation exists between companies' environmental and their financial performance. We checked out the assertion that it ‘pays to be sustainable’ by analyzing the role that criteria pertaining to sustainability and environmental orientation play in the commercial credit risk management process. Our results show that sustainability criteria can be used to predict the financial performance of a debtor and improve the predictive validity of the credit rating process. We conclude that the sustainability a firm demonstrates influences its creditworthiness as part of its financial performance. Copyright © 2008 John Wiley & Sons, Ltd and ERP Environment.
