Problem-solving rigidity and decision time.

"The present study failed to reveal any significant relationship between rigidity and decision time… . The present results suggest that attempts to explain behavioral rigidity may have to resort to more complex concepts than impulsivity and caution."

关于四川中小水电开发的几点意见

四川水能资源蕴藏量极其丰富,但中小型水电开发程度低,地方电力供需矛盾突出,制约了地方经济的发展。初步安排2000年内重点开发10条河流中的20多个重点项目。要重视中小水电站的勘测工作,合理选择装机容量、开发方式和机组总布置,使工程建设工期短、投资省、见效快。     

Design optimisation for weight, stress and cost on Airbus using epoxy resin models

Scale modelling is used to perform experimental stress analysis on aircraft components in order to iteratively reduce stress peaks and remove material in low stress areas. The scaling technique used is to model the components in CT200 epoxy resin and analyse them using reflective photoelastic coatings. This technique leads to structurally efficient or optimised components early in the design programme. Costs are reduced by obviating stress problems which would normally only be found much later during the fatigue testing of the real component, by that time of course expensive tooling will have been made and forgings produced. It is also sometimes possible that a less expensive manufacturing technique may be employed as a result of the high confidence stress data produced. Loading rigs etc. are also much lighter and cheaper than the equivalent for testing the metal components.     

Precautionary Money Demand in a Cash-in-Advance Economy with Capital

We use a stochastic cash-in-advance model with capital to analyze the behavior of economic agents with respect to a precautionary money demand. We show that the conditions under which agents demand more money than they actually spend in the shopping session differ according to the agent’s utility function parameter. When agents are highly risk averse, the precautionary money demand may arise under low technology shocks. The circumstances under which a nonbinding cash-in-advance constraint may appear are reversed in a model without capital. The reason of observed differences is the possibility of converting a fraction of output into capital, not only into real balances.JEL Classification: E41; E47     

On the diffusion of mobile phone innovations for financial inclusion

This article investigates nexuses between innovations in mobile money and financial inclusion. Demand and supply factors that affect the diffusion of mobile services as well as macro-level institutional and economic factors are taken in account. The focus is on 148 countries with data mostly consisting of 2010–2014 averages. The empirical evidence is based on Tobit regressions. The study finds that when the empirical analysis is robust to multicollinearity, two main tendencies are apparent: the significant findings of Lashitew et al. (2019) [1] are confirmed and many new significant estimated coefficients emerge. While this study confirms the findings of the underlying research, it also goes further to improve the harmony in narratives between the predictors and the outcome variables. Accordingly, by accounting for multicollinearity, the earlier findings are now more consistent across the set of predictors (i.e. demand and supply factors) and the attendant financial inclusion outcomes (i.e. mobile money accounts, mobile used to send money and mobile used to receive money).

基于模糊综合评价法的城市水生态PPP项目评价

水生态文明建设是当今水利建设的难题,为了缓解城市水生态公共项目建设资金压力,越来越多的地方政府引入PPP模式。目前,我国PPP项目的物有所值评价一般以定性评价为主,各地市根据自身情况自行开展定量评价。根据水生态项目特点,建立了较为完善的城市水生态项目定性评价的指标体系,采用聚类群决策多属性的层次分析法来确定权重,并结合改进的模糊综合评价模型对城市PPP项目进行了物有所值的评价,通过实例验证了模型的有效性。研究结果可为城市水生态项目中PPP模式的应用提供参考。
