包头市地下水－地表水联合调度多目标管理模型

运用管理模型对地下水和地表水资源优化调度，解决包头市水资源短缺问题。首先建立双层含水层地下水流数值模拟模型，并求得地下水系统单位脉冲响应函数。考虑水资源与社会、经济和环境的关系，构建地下水－地表水联合调度多目标管理模型。决策变量为潜水和承压水开采量、各地表水厂向各管理子区的供水量，主要目标为最大限度完成工业总产值、供水费用最小、最优控制地下水位和尽量满足农业灌溉用水。模型归结为求解线性目标规划问题。结果表明，优化总供水量为66638.9?104m3?a-1，其中地下水供水量为13506.2?104m3?a-1；优化方案最大限度地满足规划需水量，使有限的水资源发挥最大的经济效益；通过对地下水开采量的控制，地下水流场趋于合理。最后根据优化方案提出了宏观水资源管理对策。

伦敦、里约奥运会中国男篮进攻方式与得分效率比较研究*

通过比较中国男篮30、31届奥运会所有比赛,找出伦敦、里约奥运会中国男篮进攻投篮方式与得分效率差异,为中国队下一届奥运会比赛做参考.采用录像观察法等,运用新奥特喜马拉雅非线性编辑软件和Adobe Premiere Pro CS3非线性编辑软件,将两届奥运会中国男篮所有比赛每一次进攻投篮切割出并做分类统计,计算出中国队每名球员进攻方式及技术数据,再使用SPSS13.0进行统计分析.得出结论,30届奥运会中国队提高了进攻速度,注重个人强攻,依靠突破寻找得分机会.31届里约奥运会,队员中距离得分较为稳定,个人突破进攻稳定性有明显提高, 把握快攻机会较好,但外线队员三分远投得分能力偏低,突破分球为同伴创造投篮机会不多,创造快攻能力不足.     

“互联网+”背景下宪法国民教育新态：特征、目标与转向

政府主导推进下的宪法教育取得显著成就,但在推进过程中凸显出的教育内容不全面、教育对象覆盖面窄、教育主体单一、教育形式不丰富等问题,影响了宪法教育成效的进一步提升。以互联网为代表的现代信息技术与宪法教育的跨界融合,既可实现教育规模的全民性、终身性,又可实现教育模式的多元化、个性化,从而提升宪法国民教育实效,培养宪法信仰。"互联网+"宪法国民教育将促进灵活、开放、互助、终身、个性化宪法教育体系的构建,对宪法教育的主体、模式、对象等产生系统性变革,成为培养具有行权担责意识和能力的法治公民的创新手段。

Writing about personal goals and plans regardless of goal type boosts academic performance

Academic underachievement is a problem for both our education system and general society. Setting personal goals has the potential to impact academic performance, as many students realize through reflection that studying is a path towards realizing important life goals. Consequently, the potential impact of a brief (4–6 h), written, and staged personal goal-setting intervention on undergraduate academic performance (earned European Credit Transfer and Accumulation System credits) was investigated. Using a time-lagged quasi-experimental design, our model was tested with two first-year university goal-setting cohorts and two control cohorts (total n = 2928). The goal-setting cohorts (n = 698 and 711) showed a 22% increase in academic performance versus the control cohorts (n = 810 and 707). This increase depended on (1) the extent of participation in the 3-stage goal-setting intervention, (2) number of words written in the exercise, and (3) the specificity of students’ goal-achievement plans (GAP). Contrary to goal-setting theory, which necessitates goal-task specificity, the results revealed that it did not matter whether the students wrote about academic or non-academic goals, or a combination of both. Rather, it appeared to be the overall process of writing about their personal goals, the specificity of their strategies for goal attainment, and the extent of their participation in the intervention that led to an increase in their academic performance. This study suggests an important modification to goal-setting theory, namely a potential contagion effect of setting life goals, an academic goal primed in the subconscious, and subsequent academic performance.     

Academic,social, and well-being goals in the classroom: The dynamic interplay between multiple goals and self-regulatory processes

Much attention has been given to investigating specific self-regulatory processes within a single goal context, yet little is known about how students manage to pursue multiple goals. We adopted a multi-method approach to examine the content of college students’ (N = 365) multiple goals, interrelations of goals in a goal network, and the role of self-regulatory processes during multiple goal pursuit. First, using thematic coding of qualitative data, we identified different types of academic, social, and well-being goals that students pursue within a particular college course. Second, using data visualization, we illustrated how these goals are dynamically connected to each other within a goal network. Finally, using mediation analysis of quantitative data, we found that students’ perceptions of the interrelations of goals were associated with academic, social, and well-being outcomes, either directly or indirectly through the use of motivational regulation strategies.     

论高校人才培养框架下的创业教育目标——兼论高校创业教育课程的设置

创业教育目标既要从高校整个人才培养框架中来考察和确定,也要结合生活实际考虑目标的发展与分步实现,即在培养创业素质人才这一总体目标指引下,从低到高分层培养具有良好创业素质的社会公民、自我工作岗位的创造者以及新型企业的创办者。创业教育目标这一理论特质,要求高校创业教育课程的设置不能脱离整个人才培养的体系框架,要加强与其他课程的融合与贯通,并与创业教育的分层目标结合起来。     

Evidence‐based practice and evaluation: from insight to impact

With the growing emphasis on accountability and evidence‐based practice, evaluation has become increasingly important in the contexts in which educational psychologists (EPs) practice. This paper describes a Target Monitoring and Evaluation (TME) system, derived from Goal Attainment Scaling (GAS) which was developed to evaluate outcomes of a wide range of interventions that were established as a result of an EP and an assistant EP involvement in two local authorities. Pupils made progress on between 94% and 97% of targets, and outcomes were significantly better than the baseline for both groups. Results are considered in terms of the value and usefulness of TME as an evaluation system and key issues relating to its implementation within EP practice are discussed.     

Goal orientations and metacognitive skills of normal technical and normal academic students on project work

In 2000, the Singapore Ministry of Education launched Project Work (PW) to encourage the application of knowledge across disciplines, and to develop thinking, communication, collaboration and metacognitive skills. This preliminary findings of a large scale study examines the role of goal orientations (achievement goals and social goals) in predicting metacognition and enjoyment in project work of Secondary Two Normal Technical (NT, less academically inclined students) and Normal Academic (NA) students. Both achievement goals and social goals are significant predictors of metacognition and enjoyment of PW. NA students adopt more mastery approach and performance avoidance goals than NT students whilst NT students tend to value more social approval from others. Implications of the findings will be discussed with practical suggestions to help teachers design successful PW for the less academically inclined students.
