论社会主义市场经济与社会主义民主政治

社会主义市场经济体制与其民主政治的关系不能等同于经济基础与上层建筑的关系，而是一种具体的经济制度与民主制度特别是民主的具体运行体制和内容之间的关系。市场经济对民族政治的发展有积极影响的一方面，也有消极影响的一方面。在大力发展市场经济促进民族政治发展的同时，必须对政治体制进行改革，以实现市场经济与民主政治的共同发展。

"全国统一考试是国家意志的体现"这一提法的回顾

"全国统一考试是国家意志的体现",这一提法既有积极意义,也有历史局限,对以科学发展观来审视统一考试制度的改革完善、兴废、发展,有所裨益。     

多滞量具有正负系数的一阶中立型时滞微分方程的稳定性

本文考虑一阶中立型时滞微分方程(1): [x(t)+sum from i=1 to n_1ci(t)x(t-r_i)]~′+sum from k=1 to n_2Pk(t)x(t-τ_k)-sum from j=1 to n_3qj(t)x(t-σ_j)=0的稳定性。这里均为非负实数,我们建立了此方程的一个稳定性结果,较文献[6]讨论得更广泛,所得结论更深刻。

Inclusion of pupils with ADHD symptoms in mainstream classes with PBS

Inclusion is never only a practical issue of placement. School-wide systemic change, together with well-functioning, multi-tiered support, can promote the inclusion of all pupils. This paper draws on research conducted in two mainstream primary schools in Finland. The primary focus was to gain insight into practical solutions to facilitate the inclusion of pupils with attention-deficit hyperactivity disorder (ADHD) in mainstream teaching. Using an experimental, multiple-baseline, single-case design, we examined the effects of Check-in Check-out (CICO) support on changes in the behaviour of two pupils who displayed ADHD-type behaviours. The key features of CICO are brief morning and afternoon meetings with an adult, the use of a daily report card, regular positive feedback during the day, and parental involvement. This study examined if behavioural gains made during the implementation of CICO support can be maintained. Visual data analysis revealed differences in two CICO-ending strategies on maintenance in pupils with ADHD symptoms. The results suggest that consistent universal positive behaviour support systems together with additional behavioural support can facilitate the successful inclusion of pupils observed by teachers to have even severe disruptive behaviours in a mainstream learning environment.     

Goal Setting,Academic Reminders,and College Success: A Large-Scale Field Experiment

This article presents an independent large-scale experimental evaluation of two online goal-setting interventions. Both interventions are based on promising findings from the field of social psychology. Approximately 1,400 first-year undergraduate students at a large Canadian university were randomly assigned to complete one of two online goal-setting treatments or a control task. In addition, half of treated participants were offered the opportunity to receive follow-up goal-oriented reminders through e-mail or text messages to test a cost-effective method for increasing the saliency of treatment. Across all treatment groups, we observed no evidence of an effect on grade point average, course credits, or second-year persistence. Our estimates are precise enough to discern a 7% standardized performance effect at a 5% significance level. Our results hold by subsample, for various outcome variables, and across a number of specifications.     

新议清朝人口剧增的原因及影响

清朝人口剧增包括多方面原因,既有社会政治稳定、社会经济发展等一般原因,也有历史遗留人口基数比较大、人口统计范围扩大、高产农作物大量种植等特殊原因。赋税制度的变革在刺激人们生育的同时也使人口统计的真实性加强。庞大的人口既给清朝社会经济发展带来了负面影响,也提升了清朝的综合国力,转变了人们的生育观念,更使得大量的人口为了生存而转向工商业领域。
