基于LASSO-LARS的上市公司财务危机预警模型研究     

吴若唯  李凡群  廖国威 《安顺学院学报》2019,(2):130-135

目前,我国企业面临较大的竞争压力与风险。财务风险是影响企业经营的重要因素,故企业需要建立财务危机预警机制,对未来可能发生的风险进行管理和控制。文章从沪深A股市场中选取共80家ST与非ST上市公司的财务指标数据作为样本,运用机器学习LASSO-LARS算法提取样本中的特别变量,并求得特别变量的系数,最终形成上市公司财务危机预警模型,为上市公司决策者提供决策方向。  相似文献

Universities responding to policy: Organisational change at the University of Namibia     

Robert Kirby-Harris 《Higher Education》2003,45(3):353-374

In this article the development of the University of Namibia since itsestablishment (8 years ago) has been studied within the context of theformation of the newly-independent Southern African state of Namibia. Ahybrid framework, based on the major theoretical perspectives ofneo-institutionalism and resource dependency, has been utilized toanalyse the accounts of key respondents involved in these developmentsand hence derive an explanatory narrative of the changes involved inresponse to (government) policy.It is suggested that the major themes within this narrative may be ofexplanatory value when studying organizational change in small(developing) countries with relatively young institutions. Inparticular, the following concepts are worth highlighting: thenormatively strong but operationally weak state interacting with thenormatively weak but operationally strong institution; the commonpolitical elite, with institutional leaders sharing government values;and the relative informality of policy formulation and pluralism ofgovernment, with leading institutional actions having a policy sensingand shaping role.The loose set of themes devised from the interpretation ofsemi-structured interviews with a relatively small number of respondentscan also be considered as providing a conceptual framework for furtherresearch both within the specific institution and on a broadercomparative basis.  相似文献   

PRESSURE DROP IN THE VERTICAL PNEUMATIC PIPE FOR POWDER CONVEYING     

于荣宪  王文琪 《东南大学学报》1989,(1)

Based on the former research work of the authors,the resistance of differentsolid particle suspension flow in a vertical pipe is analysed,and investigatedexperimentally.The applicable formulas of pressure drop are presented.Two types of par-ticles,talcum powder and glass beads,are convcyed in the test which has been carried outat various air vclocities of 10 to 28 m/s and at the ratio of solids-air mass flow rateranged from 0 to 2.The experimental results show a good agreement with the calculatedones.  相似文献

INTRODUCTION The rapidly increasing application of radio fre- quency identification (RFID) includes supply chain management, access control to buildings, public transportation, airport baggage, and express parcel logistics (Karthaus and Fischer, 2003; Feldhofer, 2004; Glidden et al., 2004). Using an RFID system is a good approach for automated identification of products. RFID system consists of two major components, an interrogator (reader) and a transponder (tag), composed of an ant…  相似文献
