Effects of fixed costs in two-person sequential bargaining

Rubinstein (1982) considered the problem of dividing a given surplus between two players sequentially, and then proposed a model in which the two players alternately make and respond to each other's offers through time. He further characterized the perfect equilibrium outcomes, which depend on the players time preferences and order of moves. Using both equal and unequal bargaining cost conditions and an unlimited number of rounds, two experiments were designed to compare the perfect equilibrium model to alternative models based on norms of fairness. We report analyses of final agreements, first offers, and number of bargaining rounds, which provide limited support to the perfect equilibrium model, and then conclude by recommending a shift in focus from model testing to specification of the conditions favoring one model over another.

A hybrid ARIMA and support vector machines model in stock price forecasting

Traditionally, the autoregressive integrated moving average (ARIMA) model has been one of the most widely used linear models in time series forecasting. However, the ARIMA model cannot easily capture the nonlinear patterns. Support vector machines (SVMs), a novel neural network technique, have been successfully applied in solving nonlinear regression estimation problems. Therefore, this investigation proposes a hybrid methodology that exploits the unique strength of the ARIMA model and the SVMs model in forecasting stock prices problems. Real data sets of stock prices were used to examine the forecasting accuracy of the proposed model. The results of computational tests are very promising.     

基于提前期的多阶通用件库存模型

针对单个企业内部应用通用件的环境,在假定一个多阶生产系统的基础上,对应用通用件的库存量水平及其成本进行了分析,建立了多阶通用件库存模型,提出通过对采用通用件和不采用通用件的成本差异的比较,来决策多阶生产系统中在哪一阶工序采用通用件,并求解出每一阶工序优化的基本库存水平。

江苏省基层医务人员工作压力研究

对905名基层医务人员进行问卷调查,了解基层医务人员工作压力情况及其影响因素,为建立适合基层卫生机构的良性人才发展机制提供依据。基层医务人员整体工作压力得分为56.54分;单因素方差分析显示,不同性别、年龄、婚姻状况、学历、职称、机构类型、工作量、工作年数、受患者尊重程度和社会地位的医务人员工作压力得分差异具有统计学意义;多元线性回归分析结果显示,社会地位、工作量、工作年数、受患者尊重程度、最高学历和性别对基层医务人员工作压力的影响具有统计学意义。需要着重关注乡镇卫生院医生的工作压力情况,重点应放在提升基层医务人员社会地位、及时关注中坚力量等方面,从而减轻其工作压力,提高工作积极性。
