整体·动态·系统基模:论“落后生”的诊治

“落后生”是指那些某些方面明显落后于班级总体或是不能完成自己的学习计划未能达到本应达到的发展水平的学生。必须用整体和动态的观点来考察“落后生”的“落后”。用雷达图法、木桶原理和心理测量的有关手段可以对落后生的落后进行剖析。运用系统基模可以对“落后生”落后的原因及对策做静态和动态的探讨。

有些事不怕落后

有些事不怕落后刘双发有位指导员调到新单位上任时，听副连长汇报说连队节约伙食费五万多元，在全团名列第一。他想，那连队伙食一定不错吧。可连吃几天，都是土豆、白菜和萝卜“老三样”。经了解才知道，连队的这个“第一”是硬从官兵嘴里“抠”出来的。指导员当即与连长...

浅谈体育“落后生”存在的原因及转化途径

怎样转化体育教学中的“落后生”，是体育教师一直思索和探讨的问题。 1体育“落后生”存在的原因 1．1思想认识不明确 很多学生在思想、认识上对于身体健康的标准存在一种错觉，误认为能吃、能睡、没病就是身体好；有的认为学习忙，没有时间锻炼，体育锻炼又影响学习；还有的认为锻炼又苦又累。多吃点富有营养的食品，身体照样好；也有的认为体育课不重要。学好专业课才是主要的。体育只求60分及格就行。

不信“落后”不变样——记河北省威县人武部部长张少川

在河北省威县,熟悉人武部部长张少川的人都说他有胆识,想问题总是比别人看得远,工作抓得细,是个能干大事的人。1996年人武部转换建制时,威县人武部的整体建设水平还处于落后状态,一座灰头土脸的办公楼,两排低矮的旧瓦房,干部、职工吃饭没食堂,征兵自己没有体检站。张少川坐不住了,他决定改变这一面貌。 说干就干。张少川请了个懂行的给估算了一下,要想把人武部这座机关小院整得像回事,少说了得一二百万。作为县委常委他心中清楚。

Load-bearing characteristics and energy evolution of fractured rock masses after granite and sandstone grouting

Experiments on grouting-reinforced rock mass specimens with different particle sizes and features were carried out in this study to examine the effects of grouting reinforcement on the load-bearing characteristics of fractured rock mass.The strength and deformation features of grouting-reinforced rock mass were analyzed under different loading manners;the energy evolution mechanism of grouting-reinforced rock mass specimens with different particle sizes and features was investigated;the energy dissipation ratio and post-peak stress decreasing rate were employed to evaluate the bearing stability of grouting-reinforced rock mass.The results show that the strength and ductility of granite-reinforced rock mass(GRM)under biaxial loading are higher than that of sandstone-reinforced rock mass(SRM)under uniaxial loading.Besides,the energy evolution characteristics of grouting-reinforced rock mass under uniaxial and biaxial loading mainly could be divided into early,middle,and late stages.In the early stage,total,elastic,and dissipation energies were quite small with flatter curves;in the middle stage,elastic energy increased rapidly,whereas dissipation energy increased slowly;in the late stage,dissipation energy increased sharply.The energy dissipation ratio was used to represent the pre-peak plastic deformation.Under uniaxial loading,this ratio increased as the particle size increased and the pre-peak plastic deformation of grouting-reinforced rock mass became larger;under biaxial loading,it dropped as the particle size increased,and the pre-peak plastic deformation of grouting-reinforced rock mass became smaller.The post-peak stress decline rate A_(v) was used to assess the post-peak bearing performance of grouting-reinforced rock mass.Under uniaxial loading,parameter A_(v) exhibited reduction as the particle size kept increasing,and the ability of post-peak of grouting-reinforced rock mass to allow deformation development was greater,and the bearing capacity was greater;under biaxial loading,A_(v) increased with the particle size,and the ability of post-peak of grouting-reinforced rock mass to allow deformation development was low and the bearing capacity was reduced.The findings are considered instrumental in improving the stability of the roadway-surrounding rock by granite and sandstone grouting.

A Prognostic Model Based on Colony Stimulating Factors-related Genes in Triple-negative Breast Cancer

Objective Triple-negative breast cancer(TNBC)is the breast cancer subtype with the worst prognosis,and lacks effective therapeutic targets.Colony stimulating factors(CSFs)are cytokines that can regulate the production of blood cells and stimulate the growth and development of immune cells,playing an important role in the malignant progression of TNBC.This article aims to construct a novel prognostic model based on the expression of colony stimulating factors-related genes(CRGs),and analyze the sensitivity of TNBC patients to immunotherapy and drug therapy.Methods We downloaded CRGs from public databases and screened for differentially expressed CRGs between normal and TNBC tissues in the TCGA-BRCA database.Through LASSO Cox regression analysis,we constructed a prognostic model and stratified TNBC patients into high-risk and low-risk groups based on the colony stimulating factors-related genes risk score(CRRS).We further analyzed the correlation between CRRS and patient prognosis,clinical features,tumor microenvironment(TME)in both high-risk and low-risk groups,and evaluated the relationship between CRRS and sensitivity to immunotherapy and drug therapy.Results We identified 842 differentially expressed CRGs in breast cancer tissues of TNBC patients and selected 13 CRGs for constructing the prognostic model.Kaplan-Meier survival curves,time-dependent receiver operating characteristic curves,and other analyses confirmed that TNBC patients with high CRRS had shorter overall survival,and the predictive ability of CRRS prognostic model was further validated using the GEO dataset.Nomogram combining clinical features confirmed that CRRS was an independent factor for the prognosis of TNBC patients.Moreover,patients in the high-risk group had lower levels of immune infiltration in the TME and were sensitive to chemotherapeutic drugs such as 5-fluorouracil,ipatasertib,and paclitaxel.Conclusion We have developed a CRRS-based prognostic model composed of 13 differentially expressed CRGs,which may serve as a useful tool for predicting the prognosis of TNBC patients and guiding clinical treatment.Moreover,the key genes within this model may represent potential molecular targets for future therapies of TNBC.

贫困地区的含义和分类

一、贫困地区的含义 贫困地区大体包括以下四层含义:首先,贫困地区是一个经济范畴,即指生活资料缺乏。“贫困”通常与“落后”一词连用,称为贫困落后地区。贫困与落后之间存在着相互依存、互为因果的关系,即在实际社会经济生活中,既不存在着只贫困而不落后的地区,又不存在着只落后而不贫困的地区,但是,贫困和落后之间也存在着差别。落后地区是一个广义的概念,它除包括经济落后外,还包括文化落后、教育落后、科技落后、管理落后。换言之,落后中包含着贫困在内,既不能把二者同等看待,也不能把二者截然分开。

石月专栏:文坛风景之六——“回到自己”与“走向世界”

近代以来,炎黄子孙的自尊心只要没有畸变成阿Q式的“精神胜利”,那么,这种自尊心就成了一种动力,趋动这个古老民族急起直追,激励人们自强不息。中国的屈辱,千言万语归于一,中国落后。要摘掉这顶“落后”的帽子,除了自己努力,还能指望什么呢?因此,这—个多世纪以来,文化上的反省、政治上的革命、经济上的改革等等一系列的风云变幻,都是为了寻求一条切实的复兴之路,尽管也屡屡陷入误区,左右奔突、误入歧途,但有时候是不可避免的。人,没有先知者,也不是神仙上帝,只能在实践中摸索。 如果说,自“五四”开始,文学便和中国社会的进步、中国复兴之道的寻求宿命般地纠缠在了一起,文学的肩上自觉地负起了这样一种沉重的、使文学力不从心的使命。文学有时候被这种“使命”压弯了“腰”,然而,半个多世纪以来,伟大的、杰出的作家、诗人。

文学批评发展的征兆

文学批评落后于文学创作的发展——这是多少年来人们早已习惯了的说法。也许正因为它已经成为一个“习惯用语”,所以,人们往往就不再去详究它所指的是什么,不再去细致地分析近几年来文学批评的实际状况,而只顾笼统地把一顶“落后”的帽子扣在文学批评的头上。其实,如果我们把建国三十五年来的文学创作和文学批评。

台湾“青年诗人”的界定及研究

台湾诗坛对“青年诗人”的概念,有多种不同划分和称谓。有的称为“青年诗人”,有的称为“第三代、第四代诗人”,有的称为“新世代诗人”,有的称为“新生代诗人”,也有的称为“新锐诗人”等。其中称为“青年诗人”的,看不出有什么特别的含意,而称之为第三代、第四代诗人”的,则是包含着对台湾整个新诗人的断代划分内涵。比如张默在《台湾青年诗选》导言中写道;“假如从一九四九年算起,几乎十年为一代,目前正是四代诗人并列,各自开辟自己的道路。
