基于卫星云图的视场坐标转化模型

利用卫星云图的灰度矩阵,可以换算出经纬度等信息,并由此对不同时刻的卫星数据进行有效的风矢度量。本文运用地心坐标系统,构建了几何模型,结合lagrange插值法给出了灰度矩阵元素行列号对应于经纬度坐标的换算公式;借助Matlab软件得出了灰度矩阵中对应行、列的经纬二维数组;并用Matlab将灰度矩阵转化为卫星云图,并添加经纬信息,统一坐标系统后用Matlab绘制海岸线。     

研究生心理素质教育现状及对策探析

加强研究生心理素质教育对于提高高校研究生整体素质将起到巨大的推动作用,但由于目前对于研究生心理素质教育认识不够,管理教育措施不到位,使得相关制度不够健全.因此,高校应加大对研究生心理素质教育研究的力度,制定研究生心理素质评价指标体系,并建立一支心理素质好的专业教育队伍,同时,发挥研究生心理素质教育社团的作用,以促进研究生心理素质教育工作顺利开展.     

Adjusted empirical likelihood models with estimating equations for accelerated life tests

This article proposes an adjusted empirical likelihood estimation (AMELE) method to model and analyze accelerated life testing data. This approach flexibly and rigorously incorporates distribution assumptions and regression structures by estimating equations within a semiparametric estimation framework. An efficient method is provided to compute the empirical likelihood estimates, and asymptotic properties are studied. Real-life examples and numerical studies demonstrate the advantage of the proposed methodology.     

Maximum Likelihood Estimation of Input Demand Models with Fixed Costs of Adjustment

Traditional models of input demand rely upon convex and symmetric adjustment costs. However, the fortune of this highly restrictive approach is due more to analytical convenience than to empirical relevance. In this note we examine the model under more realistic hypothesis of fixed costs, show that it can be cast in the form of a Double Censored Random Effect Tobit Model, derive its likelihood function, and finally evaluate the performance of the ML estimators through a Monte Carlo experiment. The performances, although strongly dependent on the degree of censoring, appear to be promising.     

公司价值评估方法新思考

自19世纪60年代以来,公司并购与重组不断发生,导致对公司价值的重新评估,而评估方法的选择一直是理论界与实务界争论的焦点。因素分析法作为一种新型的方法,根据影响公司的内部因素与外部因素,分别设置详细的标准与计算公式,结合信息计算公司价值。因素分析法试图规避传统方法存在的缺陷,为公司并购双方、投资者等对公司价值的评估提供方法论借鉴。     

论仪式在生命过渡阶段的心理治疗价值

仪式作为一种社会文化现象引发了多学科的研究兴趣。在心理治疗领域,仪式的交流和变化特征使其可以成为一种治疗手段,尤其在帮助人们顺利完成生命过渡、避免心理疾病方面具有重要价值。在人们出生、成年、结婚等重要节点,仪式带给我们的心理作用不可忽略,不做处理的生命过渡会带来心理危机。仪式化的心理治疗通过意义的传递、给予心灵稳固支撑、建构自我、增强控制感、面向未来、促进联系等机制实现。     

艾米莉·狄金森的死亡美学及深层意蕴探究

美国女诗人艾米莉·狄金森被推崇为西方现代派诗歌的先驱。在其遗留下来的1 700余首诗稿中,有大约近600首诗歌是以死亡为题材的,是其一生诗作总数的三分之一。诗人从不同角度、不同层面描写死亡,向世人展现了其对死亡的独特理解。在艾米莉·狄金森的笔下,死亡主题被赋予了更深层次的意蕴。艾米莉·狄金森通过对死亡的描述,阐释了生命的终极意义,她对死亡价值的判断体现了探讨生命真谛、扩展生命张力、让精神永恒的美学思想。     

陕西省地方政府行政管理支出实证研究

在厘定统计口径的前提下,依据公开的数据、资料,从纵向和横向两个维度对陕西省政府行政管理支出进行了计算、分析和比较,并增加了行政支出对GDP占比数、人均行政支出等测算维度;研究数据表明:陕西省地方政府行政管理支出目前在全国范围内居于中等略偏下的位置,说明陕西省行政管理效率在逐步提高,行政改革也取得了一定的成效;同时,针对陕西省地方政府行政支出中的不合理因素提出解决思路。     

The “Silent Dog” Method: Analyzing the Impact of Self-Generated Rules When Teaching Different Computer Chains to Boys with Autism

The purpose of the study was to extend the literature on verbal self-regulation by using the “silent dog” method to evaluate the role of verbal regulation over nonverbal behavior in 2 individuals with autism. Participants were required to talk-aloud while performing functional computer tasks.Then the effects of distracters with increasing demands on target behavior were evaluated as well as whether self-talk emitted by Participant 1 could be used to alter Participant 2''s performance. Results suggest that participants'' tasks seemed to be under control of self-instructions, and the rules generated from Participants 1''s self-talk were effective in teaching computer skills to Participant 2. The silent dog method was useful in evaluating the possible role of self-generated rules in teaching computer skills to participants with autism.
