高职教育实践性教学初探 总被引:3,自引:1,他引:3
赵敬明 《广东农工商职业技术学院学报》2004,(3)
加强高等职业教育的实践性教学,是高等职业教育教学改革的一个关键的突破口。只有加强实践性教学的探讨和创新,才能突出高职教育的特色。要积极探讨建立实践性教学为主的模式和运行机制,如实践性教学导师制、学生模拟实习公司等。同时,要处理好理论教学与实践教学的关系,处理好培养人才"宽"与"窄"的关系。 相似文献

We compare the performance of a wide set of regression techniques and machine-learning algorithms for predicting recovery rates on non-performing loans, using a private database from a European debt collection agency. We find that rule-based algorithms such as Cubist, boosted trees, and random forests perform significantly better than other approaches. In addition to loan contract specificities, predictors that refer to the bank recovery process — prior to the portfolio’s sale to a debt collector — are also shown to enhance forecasting performance. These variables, derived from the time series of contacts to defaulted clients and client reimbursements to the bank, help all algorithms better identify debtors with different repayment ability and/or commitment, and in general those with different recovery potential. 相似文献

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural
resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical
general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced
domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite
goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare
under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than
in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and
domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare
and private consumption rise. We provide magnitudes for different parameter values.

This paper presents the theoretical development of a new threshold autoregressive model based on trended time series. The theoretical arguments underlying the model are outlined and a nonlinear economic model is used to derive the specification of the empirical econometric model. Estimation and testing issues are considered and analysed. Additionally we apply the model to the empirical investigation of U.S. GDP.This paper is the result of work carried out for the author's Ph.D. thesis.

Noisy chaotic dynamics in commodity markets 总被引:2,自引:1,他引:2
Catherine?Kyrtsou Walter C.?LabysEmail author Michel?Terraza 《Empirical Economics》2004,29(3):489-502
The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003 相似文献

Hedonic models and air pollution: Twenty-five years and counting 总被引:2,自引:1,他引:2
This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper. 相似文献
