现代社会职业存在的模式探析   总被引:1,自引:0,他引:1  
人类社会具有宏观社会系统的客观存在性、社会子系统的功能存在性的特点.通常,社会子系统的功能存在性具有:功能效果必然存在性、功能价值的积极与消极意义并存性、功能界定的主观模糊性、功能存在的历史变迁性四类主要特征.各个职业类别作为一类社会子系统,人的职业存在作为一种特殊的社会存在,同样具有功能存在性的特征.总结起来,现代社会个人的职业存在规律,可以用"职业存在的功能--受益模型"加以概括,即个体功能对社会需求和职业收益对个人需要的双重满足.  相似文献

“存在性”问题是指判断满足某种条件的事物是否存在的问题,形如“是否存在……”、“证明存在…·。·”、“总存在……”等命题形式.“存在性”问题是探索性问题的重要形式,它要求根据题设条件,把握特征,对“是否存在”要作出准确的判定和正确的推理.解决这类问题时,一般要遵循这样的思路艰0:假设“存在”——演绎推理——得出结论(合理或矛盾). 常见的存在性问题有方程的存在性问题、抛物线的存在性问题、三角形的存在性问题、直线的存在性问题等,现举例予以说明. 一、关于方程的-存在性”问回 例I(威都市中考试题B卷第三题)已知…  相似文献

教学性存在是保证在线学习成功的重要决定因素.忽视教学性存在,简单地要求学生参与网络课程论坛的活动,不能带来良好的效果.本文借助QSRN、Nvivo软件,根据探究社区理论模型而形成的内容分析编码体系,对三个课程论坛中与教学性存在有关的语意单元进行量化处理,并从设计与组织、促进对话和指导教学三个方面分析和比较其教学性存在.发现所选择的课程论坛样本中的教学基本属于无结构状态,整体教学性存在水平很低;教师忽视在线教学过程的设计与组织,在促进对话和指导教学时受灌输式教学的影响较大,缺乏必要的在线教学技能,没有把握好教师的有限存在.建议重视并提高在线教学的教学性存在,对在线教师开展关于教学性存在的培训,注重有限存在以促进协作学习开展.  相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.  相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?  相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.  相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献
