农村居民收入差距的双重经济效应分析

作为中国经济改革的切入口———收入分配领域,平均主义的剔除一开始就蕴含着拉开收入差距的必然趋势,经济学界对收入差距或者收入分配与经济增长的关系主要有两种观点:一种认为收入差距太大不会对经济增长会产生不利影响。一种认为收入差距太大对经济增长会产生不利影响。伴随着农村居民收入水平的提高,农村居民的收入差距也渐次拉开,对此的经济学分析表明,收入差距对经济增长的负效应远大于其对经济增长的正效应,直接影响到农村和谐社会的建设。

Laplace-normal mixtures fitted to wind shear data

A mixture model with Laplace and normal components is fitted to wind shear data available in grouped form. A set of equations is presented for iteratively estimating the parameters of the model using an application of the EM algorithm. Twenty-four sets of data are examined with this technique, and the model is found to give a good fit to the data. Some hypotheses about the parameters in the model are discussed in light of the estimates obtained.

The development and construct validation of a consumer satisfaction questionnaire for psychiatric inpatients.

A consumer satisfaction scale was developed for psychiatric inpatients. The scale was administered to a state-wide sample of (n = 366) patients discharged from acute psychiatric units throughout Missouri. The scale was factor analyzed and given to another sample of (n = 390) discharges. Three out of five factors that were found in the first sample were replicated in a factor analysis of data from the second sample. Acceptable coefficient alphas were obtained on all three factors, demonstrating internal reliability. The three factors were labeled Treatment Effectiveness, Trust of Staff, and Hospital Environment. Comparable levels of satisfaction with prior studies were found on the first general satisfaction factor of Treatment Effectiveness. Subjects discriminated areas of satisfaction by expressing higher levels of dissatisfaction on the factors of Trust of Staff and Hospital Environment.
