主体性与主导性相统一:思想政治教育的创新之基

针对当前思想政治教育面临的教学话语、教育理念、教学主体及教学评价等方面的创新困境,高校和思想政治教师应从多方入手,以学生主体和教师主导为依据,转化教学话语和教育理念,以主导性和主体性相统一为导向选择合适的教学模式、明确教学评价机制,促进学生主体性作用、教师主导性作用及二者相统一作用的实现,进而帮助思想政治教育提升教学效果,实现创新。     

优势分析:确定回归方程预测指标相对重要性的统计方法

确定多元回归方程中各预测指标相对重要性的传统方法具有模型依赖性特征 ,无法在多元回归模型衍生出的不同子模型中使相对重要性指标保持恒定不变。 Budescu(1993)近来提出的优势分析 ,则克服了上述缺点。优势分析将各预测指标对因变量总方差的贡献分解为已预测方差百分比 ,从而使各预测指标的相对重要性得以更精确地表现出来 ;同时 ,优势分析产生的各预测指标的已预测方差百分比还具有模型独立性特征 ,不受多元回归模型中不同预测指标不同组合的影响。通过运动员生活满意感的一个研究实例讨论了优势分析的操作过程、统计意义和应用前景。     

谈伊拉克战事中美国反常规的舆论控制方式

此次伊拉克战争中 ,美军所采取的反常规舆论控制方法达到甚至超过了预期的效果。这种“反常规控制”对来自不同信息源的信息不封锁 ,不设限 ,有意创造一种透明而对称的信息传播环境 ,让各种声音同时存在 ,彼此碰撞 ,又相互补充 ,提供一种多样化的报道视角和全方位的战事新闻景观 ;同时避免了单一信息环境下非正式渠道虚假信息传播带来的负效应 ,在对比和相互印证的基础上强化了主体传媒的权威性和可信度。这种更具策略性的舆论控制方式为我们提供了一个成功的案例。     

基于集值信息系统的扩充粗糙集模型

借助于属性集值的相似程度在集值信息系统上定义了一种新的带有参数的优势关系-α-优势关系,并研究了其性质;同时比较了两类优势关系,得到的结论是:只要合理地设置阈值α就可以提高分类的精度,从而提高对数据预测、分类的准确度.     

以实验为主导的高职有机化学教学模式的探索与实践

基于有机化学课程目前的教学现状。针对高职学生特点,提出了以“实验为主导”的教学模式替代传统教学模式的改革试验。即同样的知识内容通过实验、实训来开展,理论与实践教学基本同步,实现课堂教学“理实一体化”。教学实践证实,该种教学模式更符合高职教育的特点和规律,能充分调动学生学习积极性和主动性,在对照的几个班级教学中取得明显的效果。     

Association between knee-to-hip flexion ratio during single-leg vertical landings,and strength and range of motion in professional soccer players

Abstract

The aim of this study was to test the correlation between knee-to-hip flexion ratio during a single leg landing task and hip and knee strength, and ankle range of motion. Twenty-four male participants from a professional soccer team performed a continuous single leg jump-landing test during 10s, while lower limb kinematics data were collected using a motion analysis system. After biomechanical testing, maximal isometric hip (abduction, extension, external rotation), knee extension and flexion strength were measured. Maximum ankle dorsiflexion range of motion was assessed statically using the weight bearing lunge test. Pearson correlation coefficients were calculated to determine the associations between the predictor variables (knee and hip strength, and ankle ROM) and the main outcome measure (knee-to-hip flexion ratio). Correlation between knee-to-hip flexion ratio and hip abductors strength was significant (r = ?0.47; p = 0.019). No other significant correlations were observed among the variables (p > 0.05). These results demonstrated that a lower hip abductors strength in male soccer players was correlated with a high knee-to-hip flexion ratio during landing from a single leg jump, potentially increasing knee overload by decreasing energy absorption at the hip. The results provide a novel proposal for the functioning of hip muscles to control knee overload.     

Hemispheric laterality in music and math

Hemispheric laterality may be a useful concept in teaching, learning, training, and in understanding more about human development. To address this issue, a measure of hemispheric laterality was compared to musical and mathematical ability. The Human Information Processing Survey (HIPS) instrument, designed to measure hemispheric laterality, was administered to 101 participants who were then asked to provide a measure of their conceptual aptitude for mathematics and music. Scores were then compared through canonical correlation to test the hypothesis that perceived mathematical ability may be explained by left-brain hemisphere preference and musical by the right hemisphere. A relatively strong correlation was found between music ability and right-brain hemisphere preference. A relationship between math and left-brain hemisphere preference or integrated brain processing scores was found to be marginal. Ramifications to learning are discussed.     

思想政治理论课主导性与主体性相统一的反思与探索

坚持主导性与主体性相统一是推进新时代思政课改革创新的关键所在。但在思政课教学过程中,依然存在着教师自身发展受限导致主导性不强,学生缺乏动力导致主体性不足;片面强调主导性走向教师中心,片面强调主体性走向主体泛化等现象,因而导致主导性与主体性相脱节的现实问题。对此,要把握好“两力”作用、处理好“两要”关系、构建“双向”模式,推动师与生的教学相长,教与学的有机统一,从而加强新时代思政课的思想性、理论性和针对性。     

有限的概念术语 无限的发展前景——论王希杰先生的"三一"修辞学理论

当代语言学、修辞学大家王希杰先生的“三一”修辞学理论，反愉部修辞学的问题建立在以下三组概念之上：四个世界、零度和偏离、显性和潜性。这个理论体系抽象出了当代修辞学最重要最基本的概念，提高了 修辞学的科学品位和社会功能，因此，可望为21世纪的修辞学研究带来无限广阔的发展前景。     

试析古代东北民族文化与其入主中原

中国古代东北民族主要有秽貊、肃慎、东胡、汉4大族系,基于独特的地理、气候条件,古代东北民族在长期的历史发展过程中形成了以游、猎经济为主,游牧、渔猎、农耕3种生产方式并存的经济特征。在此基础上,古代东北民族共同缔造了独具特色的东北文化圈,其逐水草而轻迁、尚竞技而强悍、轻礼法而自然的民族性格和民族文化,从文化学角度解释了古代东北民族入主中原这一独特的历史现象。
